[Low concentration level of total serum cholesterol as a risk factor for suicidal and aggressive behavior] [Article in Polish]

Ainiyet J, Rybakowski J. Kliniki Psychiatrii Doroslych AM w Poznaniu.

Psychiatr Pol 1996 May-Jun;30(3):499-509

The data have been presented for possible association between low total serum cholesterol concentration and the increased risk of suicidal and aggressive behavior. The analysis of results from some long-term epidemiological studies shows an excess of suicides and violent death cases among persons with low baseline total serum cholesterol level and in those in whom this level was lowered by means of pharmacotherapy or dieting. In patients hospitalized on psychiatric wards, having low total serum cholesterol concentration, a higher intensity of suicidal thoughts and tendencies was found. Such relationship was most evident in patients with depression. In some populations, an association between low total cholesterol level and the tendency to aggressive behavior was also found. Higher intensity of aggression was also observed in animals receiving low-cholesterol diet. A hypothesis was discussed, postulating the connection between low cholesterol level and lower activity of central serotonergic structures responsible for the inhibition of impulsive behavior.

Nutrition and depression: the role of folate.

Alpert JE, Fava M. Department of Psychiatry, Harvard Medical School, Boston, MA 02114, USA.

Nutr Rev 1997 May;55(5):145-9

A relationship between folate and neuropsychiatric disorders has been inferred from clinical observation and from the enhanced understanding of the role of folate in critical brain metabolic pathways. Depressive symptoms are the most common neuropsychiatric manifestation of folate deficiency. Conversely, borderline low or deficient serum or red blood cell folate levels have been detected in 15-38% of adults diagnosed with depressive disorders. Recently, low folate levels have been linked to poorer antidepressant response to selective serotonin reuptake inhibitors. Factors contributing to low serum folate levels among depressed patients as well as the circumstances under which folate and its derivatives may have a role in antidepressant pharmacotherapy must be further clarified.

Babyak M, Blumenthal JA, Herman S, Khatri P, Doraiswamy M, Moore K, Craighead WE, Baldewicz TT, Krishnan KR. Department of Psychiatry and Behavioral Sciences, Duke University Medical Center, Durham, NC 27710, USA.

Psychosom Med 2000 Sep-Oct;62(5):633-8

OBJECTIVE: The purpose of this study was to assess the status of 156 adult volunteers with major depressive disorder (MDD) 6 months after completion of a study in which they were randomly assigned to a 4-month course of aerobic exercise, sertraline therapy, or a combination of exercise and sertraline. METHODS: The presence and severity of depression were assessed by clinical interview using the Diagnostic Interview Schedule and the Hamilton Rating Scale for Depression (HRSD) and by self-report using the Beck Depression Inventory. Assessments were performed at baseline, after 4 months of treatment, and 6 months after treatment was concluded (ie, after 10 months). RESULTS: After 4 months patients in all three groups exhibited significant improvement; the proportion of remitted participants (ie, those who no longer met diagnostic criteria for MDD and had an HRSD score < 8) was comparable across the three treatment conditions. After 10 months, however, remitted subjects in the exercise group had significantly lower relapse rates (p = .01) than subjects in the medication group. Exercising on one's own during the follow-up period was associated with a reduced probability of depression diagnosis at the end of that period (odds ratio = 0.49, p = .0009). CONCLUSIONS: Among individuals with MDD, exercise therapy is feasible and is associated with significant therapeutic benefit, especially if exercise is continued over time.

Changes in the pituitary-testicular system with age.

Baker HW, Burger HG, de Kretser DM, Hudson B, O'Connor S, Wang C, Mirovics A, Court J, Dunlop M, Rennie GC

Clin Endocrinol (Oxf) 1976 Jul;5(4):349-72

In order to provide a comprehensive account of pituitary-testicular function in man, 466 subjects, ranging in age from 2 to 101 years, were studied to examine blood levels of the pituitary gonadotrophins (LH and FSH), the sex steroids testosterone and oestradiol, the binding capacity of the sex hormone binding globulin (SHBG), the free testosterone and oestradiol fractions, and the transfer constant for the peripheral conversion of testosterone to oestradiol. The results were compared with clinical indices of testicular size, sexual function and secondary sex hair distribution. Serum LH and FSH were low before puberty, increased in pubertal adolescents to levels somewhat above those of adults and subsequently increased progressively over the age of 40 years. Testosterone levels fell slowly after the age of 40, while there was a slight rise in plasma oestradiol with increasing age. FSH and testosterone showed small seasonal variations in young adult men, the lowest values being seen in winter. SHBG binding capacity was high in two prepubertal boys, fell in adult men, but increased in old age. Free testosterone and oestradiol levels fell in old age. The metabolic clearance rates (MCR) of testosterone and oestradiol also fell in old age, while the conversion of testosterone to oestradiol was increased. Many correlations were observed between various hormonal and clincial measurements. The evidence is consistent with a primary decrease in testicular function over the age of 40 years.

Bioavailable testosterone and depressed mood in older men: the Rancho Bernardo Study.

Barrett-Connor E, Von Muhlen DG, Kritz-Silverstein D. Department of Family and Preventive Medicine, School of Medicine, University of California, San Diego, La Jolla 92093-0607, USA.

J Clin Endocrinol Metab 1999 Feb;84(2):573-7

A cross-sectional population-based study examined the association between endogenous sex hormones and depressed mood in community-dwelling older men. Participants included 856 men, ages 50-89 yr, who attended a clinic visit between 1984-87. Total and bioavailable testosterone, total and bioavailable estradiol, and dihydrotestosterone levels were measured by radioimmunoassay in an endocrinology research laboratory. Depressed mood was assessed with the Beck Depression Inventory (BDI). Levels of bioavailable testosterone and bioavailable estradiol decreased with age, but total testosterone, dihydrotestosterone, and total estradiol did not. BDI scores increased with age. Low bioavailable testosterone levels and high BDI scores were associated with weight loss and lack of physical activity, but not with cigarette smoking or alcohol intake. By linear regression or quartile analysis the BDI score was significantly and inversely associated with bioavailable testosterone (both Ps = 0.007), independent of age, weight change, and physical activity; similar associations were seen for dihydrotestosterone (P = 0.048 and P = 0.09, respectively). Bioavailable testosterone levels were 17% lower for the 25 men with categorically defined depression than levels observed in all other men (P = 0.01). Neither total nor bioavailable estradiol was associated with depressed mood. These results suggest that testosterone treatment might improve depressed mood in older men who have low levels of bioavailable testosterone. A clinical trial is necessary to test this hypothesis.

Brief communication. Vitamin B1, B2, and B6 augmentation of tricyclic antidepressant treatment in geriatric depression with cognitive dysfunction.

Bell IR, Edman JS, Morrow FD, Marby DW, Perrone G, Kayne HL, Greenwald M, Cole JO. Department of Psychiatry, Harvard Medical School.

J Am Coll Nutr 1992 Apr;11(2):159-63

This was a 4-week randomized placebo-controlled double-blind study to assess augmentation of open tricyclic antidepressant treatment with 10 mg each of vitamins B1, B2, and B6 in 14 geriatric inpatients with depression. The active vitamin group demonstrated significantly better B2 and B6 status on enzyme activity coefficients and trends toward greater improvement in scores on ratings of depression and congnitive function, as well as in serum nortriptyline levels compared with placebo-treated subjects (Ss). Without specific supplementation, B12 levels increased in Ss receiving B1/B2/B6 and decreased in placebo Ss. These findings offer preliminary support for further investigation of B complex vitamin augmentation in the treatment of geriatric depression.

Mood alteration with yoga and swimming: aerobic exercise may not be necessary.

Berger BG, Owen DR. Department of Physical Education, Brooklyn College, City University of New York 11210.

Percept Mot Skills 1992 Dec;75(3 Pt 2):1331-43

The mood benefits of Hatha yoga and swimming, two activities that differ greatly in aerobic training benefits, were examined. College students (N = 87) in two swimming classes, a yoga class, and a lecture-control class completed mood and personality inventories before and after class on three occasions. A multivariate analysis of variance indicated that both yoga participants (n = 22) and swimmers (n = 37) reported greater decreases in scores on Anget, Confusion, Tension, and Depression than did the control students (n = 28). The consistent mood benefits of yoga supported our earlier observation that the exercise need not be aerobic to be associated with mood enhancement. However, underlying and causal mechanisms remain uncertain. Among the men, the acute decreases in Tension, Fatigue, and Anger after yoga were significantly greater than those after swimming. Yoga may be even more beneficial than swimming for men who personally select to participate. The women reported fairly similar mood benefits after swimming and yoga. It seems that aerobic exercise may not be necessary to facilitate the mood benefits. Also, students with greater mood changes attended class more regularly than those who reported fewer psychological benefits. Maximizing the immediate psychological benefits of exercise might be one way to encourage adults to be physically active.

Familial gynecomastia with increased extraglandular aromatization of plasma carbon19-steroids.

Berkovitz GD, Guerami A, Brown TR, MacDonald PC, Migeon CJ

J Clin Invest 1985 Jun;75(6):1763-9

We evaluated a family in which gynecomastia occurred in five males in two generations. In each affected subject, gynecomastia and male sexual maturation began at an early age. The ratio of the concentration of plasma estradiol-17 beta to that of plasma testosterone was elevated in each affected subject. In the three siblings with gynecomastia, the transfer constant of conversion of androstenedione to estrone (i.e., the fraction of plasma androstenedione that was converted to estrone as measured in the urine) was 10 times that of normal persons. The transfer constant of conversion of testosterone to estradiol-17 beta in the one subject studied also was 8-10 times that of normal men, whereas the transfer constants of conversion of estrone to estradiol-17 beta and of estradiol-17 beta to estrone were normal. Despite the elevation in extraglandular aromatase activity, there was a normal response of the hypothalamic-pituitary axis to provocative stimuli. This is the second documentation of gynecomastia that is associated with increased extraglandular aromatase activity, and the first time that the defect was found to be familial with a probable X-linked (or autosomal dominant, sex limited) mode of inheritance.

Efficacy of S-adenosyl-L-methionine in speeding the onset of action of imipramine

Berlanga C, Ortega-Soto HA, Ontiveros M, Senties H Special Studies Clinic, Mexican Institute of Psychiatry, Tlalpan. Psychiatry Res 1992 Dec;44(3):257-62

A double-blind clinical trial was carried out to evaluate the efficacy of S-adenosyl-L-methionine (SAMe) in speeding the onset of action of imipramine (IMI). SAMe is a naturally occurring substance that has been shown to possess antidepressant activity with a rapid mode of onset and minimal side effects. Sixty-three outpatients with moderate to severe depression were included in the study. After an initial 1-week placebo period, only 40 patients entered the active treatment phase. During the first 2 weeks of the trial, half of these patients received 200 mg/day of SAMe intramuscularly, while the other half received placebo. Simultaneously, oral IMI was administered to all patients at a fixed dose of 150 mg/day. The onset of clinical response was determined by evaluating patients every second day. By the end of week 2, the parenteral treatment was suppressed and IMI was adjusted according to individual needs. Depressive symptoms decreased earlier in the patients who were receiving the SAMe-IMI combination than in those who were receiving the placebo-IMI combination.

5-Hydroxytryptophan: a clinically-effective serotonin precursor.

Birdsall TC. 73541.2166@compuserve.com

Altern Med Rev 1998 Aug;3(4):271-80

5-Hydroxytryptophan (5-HTP) is the intermediate metabolite of the essential amino acid L-tryptophan (LT) in the biosynthesis of serotonin. Intestinal absorption of 5-HTP does not require the presence of a transport molecule, and is not affected by the presence of other amino acids; therefore it may be taken with meals without reducing its effectiveness. Unlike LT, 5-HTP cannot be shunted into niacin or protein production. Therapeutic use of 5-HTP bypasses the conversion of LT into 5-HTP by the enzyme tryptophan hydroxylase, which is the rate-limiting step in the synthesis of serotonin. 5-HTP is well absorbed from an oral dose, with about 70 percent ending up in the bloodstream. It easily crosses the blood-brain barrier and effectively increases central nervous system (CNS) synthesis of serotonin. In the CNS, serotonin levels have been implicated in the regulation of sleep, depression, anxiety, aggression, appetite, temperature, sexual behaviour, and pain sensation. Therapeutic administration of 5-HTP has been shown to be effective in treating a wide variety of conditions, including depression, fibromyalgia, binge eating associated with obesity, chronic headaches, and insomnia.

L-deprenyl plus L-phenylalanine in the treatment of depression.

Birkmayer W, Riederer P, Linauer W, Knoll J.

J Neural Transm 1984;59(1):81-7

The antidepressive efficacy of 1-deprenyl (5-10 mg daily) plus 1-phenylalanine (250 mg/day) has been evaluated in 155 unipolar depressed patients. Both oral and intravenous administration showed beneficial effects in 90% of outpatients and 80.5% of inpatients. It is concluded that this combined treatment has a potent antidepressive action based on the accumulation of 1-phenylethylamine in the brain.

Dehydroepiandrosterone treatment of midlife dysthymia.

Bloch M, Schmidt PJ, Danaceau MA, Adams LF, Rubinow DR. Behavioral Endocrinology Branch, National Institute of Mental Health, Bethesda, MD 20892-1276, USA.

Biol Psychiatry 1999 Jun 15;45(12):1533-41

BACKGROUND: This study evaluated the efficacy of the adrenal androgen, dehydroepiandrosterone, in the treatment of midlife-onset dysthymia.

METHODS: A double-blind, randomized crossover treatment study was performed as follows: 3 weeks on 90 mg dehydroepiandrosterone, 3 weeks on 450 mg dehydroepiandrosterone, and 6 weeks on placebo. Outcome measures consisted of the following. Cross-sectional self-ratings included the Beck Depression Inventory, and visual analogue symptom scales. Cross-sectional objective ratings included the Hamilton Depression Rating Scale, the Cornell Dysthymia Scale and a cognitive test battery. Seventeen men and women aged 45 to 63 years with midlife-onset dysthymia participated in this study. Response to dehydroepiandrosterone or placebo was defined as a 50% reduction from baseline in either the Hamilton Depression Rating Scale or the Beck Depression Inventory.

RESULTS: In 15 patients who completed the study, a robust effect of dehydroepiandrosterone on mood was observed compared with placebo. Sixty percent of the patients responded to dehydroepiandrosterone at the end of the 6-week treatment period compared with 20% on placebo. A significant response was seen after 3 weeks of treatment on 90 mg per day. The symptoms that improved most significantly were anhedonia, loss of energy, lack of motivation, emotional "numbness," sadness, inability to cope, and worry. Dehydroepiandrosterone showed no specific effects on cognitive function or sleep disturbance, although a type II error could not be ruled out.

CONCLUSIONS: This pilot study suggests that dehydroepiandrosterone is an effective treatment for midlife-onset dysthymia.

Effects of exercise training on older patients with major depression.

Blumenthal JA, Babyak MA, Moore KA, Craighead WE, Herman S, Khatri P, Waugh R, Napolitano MA, Forman LM, Appelbaum M, Doraiswamy PM, Krishnan KR. Department of Psychiatry and Behavioral Sciences, Duke University Medical Center, Durham, NC 27710, USA. blume003@mc.duke.edu

Arch Intern Med 1999 Oct 25;159(19):2349-56

BACKGROUND: Previous observational and interventional studies have suggested that regular physical exercise may be associated with reduced symptoms of depression. However, the extent to which exercise training may reduce depressive symptoms in older patients with major depressive disorder (MDD) has not been systematically evaluated.

OBJECTIVE: To assess the effectiveness of an aerobic exercise program compared with standard medication (ie, antidepressants) for treatment of MDD in older patients, we conducted a 16-week randomized controlled trial.

METHODS: One hundred fifty-six men and women with MDD (age, < or = 50 years) were assigned randomly to a program of aerobic exercise, antidepressants (sertraline hydrochloride), or combined exercise and medication. Subjects underwent comprehensive evaluations of depression, including the presence and severity of MDD using Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition criteria and Hamilton Rating Scale for Depression (HAM-D) and Beck Depression Inventory (BDI) scores before and after treatment. Secondary outcome measures included aerobic capacity, life satisfaction, self-esteem, anxiety, and dysfunctional cognitions.

RESULTS: After 16 weeks of treatment, the groups did not differ statistically on HAM-D or BDI scores (P = .67); adjustment for baseline levels of depression yielded an essentially identical result. Growth curve models revealed that all groups exhibited statistically and clinically significant reductions on HAM-D and BDI scores. However, patients receiving medication alone exhibited the fastest initial response; among patients receiving ombination therapy, those with less severe depressive symptoms initially showed a more rapid response than those with initially more severe depressive symptoms.

CONCLUSIONS: An exercise training program may be considered an alternative to antidepressants for treatment of depression in older persons. Although antidepressants may facilitate a more rapid initial therapeutic response than exercise, after 16 weeks of treatment exercise was equally effective in reducing depression among patients with MDD.

The clinical potential of ademetionine (S-adenosylmethionine) in neurological disorders

Bottiglieri T, Hyland K, Reynolds EH Metabolic Disease Center, Baylor Research Institute, Dallas, Texas.

Drugs 1994 Aug;48(2):137-52

This review focuses on the biochemical and clinical aspects of methylation in neuropsychiatric disorders and the clinical potential of their treatment with ademetionine (S-adenosylmethionine; SAMe). SAMe is required in numerous transmethylation reactions involving nucleic acids, proteins, phospholipids, amines and other neurotransmitters. The synthesis of SAMe is intimately linked with folate and vitamin B12 (cyanocobalamin) metabolism, and deficiencies of both these vitamins have been found to reduce CNS SAMe concentrations. Both folate and vitamin B12 deficiency may cause similar neurological and psychiatric disturbances including depression, dementia, myelopathy and peripheral neuropathy. SAMe has a variety of pharmacological effects in the CNS, especially on monoamine neurotransmitter metabolism and receptor systems. SAMe has antidepressant properties, and preliminary studies indicate that it may improve cognitive function in patients with dementia. Treatment with methyl donors (betaine, methionine and SAMe) is associated with remyelination in patients with inborn errors of folate and C-1 (one-carbon) metabolism. These studies support a current theory that impaired methylation may occur by different mechanisms in several neurological and psychiatric disorders.

Homocysteine, folate, methylation, and monoamine metabolism in depression.

Bottiglieri T, Laundy M, Crellin R, Toone BK, Carney MW, Reynolds EH. Department of Neurology, King's College Hospital, London, UK.

J Neurol Neurosurg Psychiatry 2000 Aug;69(2):228-32

OBJECTIVES: Previous studies suggest that folate deficiency may occur in up to one third of patients with severe depression, and that treatment with the vitamin may enhance recovery of the mental state. There are, however, difficulties in interpreting serum and red cell folate assays in some patients, and it has been suggested that total plasma homocysteine is a more sensitive measure of functional folate (and vitamin B12) deficiency. Other studies suggest a link between folate deficiency and impaired metabolism of serotonin, dopamine, and noradrenaline (norepinephrine), which have been implicated in mood disorders. A study of homocysteine, folate, and monoamine metabolism has, therefore, been undertaken in patients with severe depression.

METHODS: In 46 inpatients with severe DSM III depression, blood counts, serum and red cell folate, serum vitamin B12, total plasma homocysteine, and, in 28 patients, CSF folate, S-adenosylmethionine, and the monoamine neurotransmitter metabolites 5HIAA, HVA, and MHPG were examined. Two control groups comprised 18 healthy volunteers and 20 patients with neurological disorders, the second group undergoing CSF examination for diagnostic purposes.

RESULTS: Twenty four depressed patients (52%) had raised total plasma homocysteine. Depressed patients with raised total plasma homocysteine had significant lowering of serum, red cell, and CSF folate, CSF S-adenosylmethionine and all three CSF monoamine metabolites. Total plasma homocysteine was significantly negatively correlated with red cell folate in depressed patients, but not controls.

CONCLUSIONS: Utilising total plasma homocysteine as a sensitive measure of functional folate deficiency, a biological subgroup of depression with folate deficiency, impaired methylation, and monoamine neurotransmitter metabolism has been identified. Detection of this subgroup, which will not be achieved by routine blood counts, is important in view of the potential benefit of vitamin replacement.

Comparison of an extract of hypericum (LI 160) and sertraline in the treatment of depression: a double-blind, randomized pilot study.

Brenner R, Azbel V, Madhusoodanan S, Pawlowska M. St. John's Episcopal Hospital, Far Rockaway, New York 11691, USA.

Clin Ther 2000 Apr;22(4):411-9

BACKGROUND: Hypericum (St. John's wort) has been shown to be as efficacious and well tolerated as standard antidepressants in the treatment of depression but has not been compared with selective serotonin reuptake inhibitors (SSRIs).

OBJECTIVE: This study compared hypericum and the SSRI sertraline in the treatment of depression.

METHODS: In a double-blind, randomized study conducted in a community hospital, 30 male and female outpatients (19 women, 11 men; mean age, 45.5 years) with mild to moderate depression received 600 mg/d of a standardized extract of hypericum (LI 160) or 50 mg/d sertraline for I week, followed by hypericum 900 mg/d or sertraline 75 mg/d for 6 weeks.

RESULTS: The severity of symptoms, as assessed by scores on the Hamilton Rating Scale for Depression (HAM-D) and the Clinical Global Impression scale, was significantly reduced in both treatment groups (< 0.01). Clinical response (defined as a < or =50% reduction in HAM-D scores) was noted in 47% of patients receiving hypericum and 40% of those receiving sertraline. The difference was not statistically significant. Both agents were well tolerated. A post hoc power analysis indicated that failure to reach statistical significance between treatments resulted primarily from an absence of clinical differences rather than the small sample size.

CONCLUSION: The hypericum extract was at least as effective as sertraline in the treatment of mild to moderate depression in a small group of outpatients.

S-adenosyl-l-methionine (SAMe) as antidepressant: Meta-analysis of clinical studies

Bressa GM Department of Psychiatry, University Cattolica Sacro Cuore School of Medicine, Rome, Italy.

Acta Neurol Scand Suppl 1994;154:7-14

Introduction - S-adenosyl-l-methionine (SAMe) is a naturally-occurring substance which is a major source of methyl groups in the brain. Material and methods - We conducted a meta-analysis of the studies on SAMe to assess the efficacy of this compound in the treatment of depression compared with placebo and standard tricyclic antidepressants. Results - Our meta-analysis showed a greater response rate with SAMe when compared with placebo, with a global effect size ranging from 27% to 38% depending on the definition of response, and an antidepressant effect comparable with that of standard tricyclic antidepressants. Conclusion - The efficacy of SAMe in treating depressive syndromes and disorders is superior with that of placebo and comparable to that of standard tricyclic antidepressants. Since SAMe is a naturally occurring compound with relatively few side-effects, it is a potentially important treatment for depression.

[Effect of pyridoxine on the psychopathology and pathochemistry of involutional depressions] [Article in Russian]

Bukreev VI.

Zh Nevropatol Psikhiatr Im S S Korsakova 1978;78(3):402-8

In agreement with the catecholamine hypotheses of affective disorders the main role in the pathogenesis of depressive states is allocated to the central "noradrenergic insufficiency". The author thinks it feasible to use pyridoxine (vit. B6) in the treatment of depressive states, inasmuch as it is involved in the process of catecholamine synthesis as a cofactor of DOPA-decarboxylase. The author examined 48 patients among which 31 were with involutional melancholia and 17 with manic-depressive psychoses, manifesting after 40 years. Along with a positive therapeutical effect there was an increase in the noradrenaline excretion and a drop in the relative adrenaline content.

Neuropsychiatric disorders associated with nutritional deficiencies. Incidence and therapeutic implications

Carney M.W.P. Hill House, Mount Park Road,Harrow-on-the-Hill, Middlesex HA13JY United Kingdom

CNS Drugs ( CNS DRUGS ) (New Zealand) 1995, 3/4 (279-290) Deficiencies of various vitamins are associated with a variety of neuropsychiatric manifestations. Depression is a feature of deficiencies of folic acid, vitamin B 2 (riboflavin) and vitamin B 6 (pyridoxine), while vitamin B 1 (thiamine) deficiency is associated with several psychosyndromes including alcoholism and schizophrenia. Data from recent studies of vitamin deficiency reveal that gross manifestations such as beri-beri (characteristics include Wernicke's encephalopathy and Korsakoff's syndrome) and pellagra (characteristics include fatigue, insomnia and encephalopathy) are now relatively rare in the Western world. However, milder and subclinical syndromes are still common. For example, the prevalence of low levels of vitamin B 12 (cyanocobalamin) is has been estimated to be 5.8 to 26.1% in psychiatric patients, while that of folic acid is higher at 15 to 51% (derived from various studies). Despite these apparent associations, whether deficiencies of vitamins are causal in neuropsychiatric disorders or a result of them is difficult to determine. For example, there is little direct evidence of a causal role for folic acid in neuropsychiatric disorders, except in the rare in-born errors of metabolism that present with neuropsychiatric abnormalities. It is known that folic acid deficiency is associated with the use of many therapeutic drugs, concomitant physical illnesses and chronicity of psychiatric illness. However, retrospective studies of the effects of folic acid replacement therapy in deficient patients, employing clinical and social outcome criteria, have shown an improvement in psychiatric symptoms over a period of 6 to 12 months in most patients. Controlled studies of folic acid replacement therapy are also encouraging. In 1 double-blind, placebo-controlled add-on trial involving patients with endogenous depression and schizophrenia, the majority of folic acid treated patients improved compared with placebo recipients. The situation with regard to a causal role for other vitamins in neuropsychiatric disorders is even less clear. Obviously, more data are needed in this area to assist clinicians in determining the aetiology of episodes of depression and other neuropsychiatric disorders and, ultimately, their treatment.

Red cell folate concentrations in psychiatric patients

Carney M.W.P.; Chary T.K.N.; Laundy M.; Bottiglieri T.; Chanarin I.; Reynolds E.H.; Toone B. Department of Psychiatry, Clinical Research Centre, Northwick Park Hospital, Watford Road,Harrow HA1 3UJ United Kingdom

Journal of Affective Disorders ( J. AFFECT. DISORD. ) (Netherlands) 1990, 19/3 (207-213) Red cell folate and vitamin B12 estimations were performed on 243 successively admitted in-patients at a District General Hospital Psychiatric Unit and 42 out-patients (29 attending a lithium clinic). Patients were classified into five diagnostic groups. The mean ages of the manic and schizophrenic patients were lower than of the depressed or euthymic patients but age was not correlated with red cell folate or serum B12 levels in any group. There were 89 (31%) patients with red cell folate below 200 ng/ml and 35 (12%) with concentrations below 150 ng/ml. Significantly more of these low-folate patients were in-patients than outpatients. The mean red cell folate in the depressed patients was significantly lower than in the euthymic, manic and schizophrenic groups. Alcoholics had a similar mean red cell folate to depressed patients which was not quite significantly lower than the other groups. The mean serum B12 level in the alcoholics was, however, significantly raised. There were no significant differences in red cell folate or serum B12 between lithium-treated and untreated euthymic patients. The highest proportions of values below 200 ng/ml and 150 ng/ml were found in depressed and alcoholic patients. Endogenous depressives had the highest percentage of values below 150 ng/ml (folate-deficient) of all psychiatric groups and alcoholic patients. The significance of these findings is discussed.

A controlled clinical trial of L-tryptophan in acute mania.

Chouinard G, Young SN, Annable L.

Biol Psychiatry 1985 May;20(5):546-57

In a 2-week study, 24 newly admitted manic patients were treated for 1 week with L-tryptophan (12 g/day); during the second week, half the patients, chosen at random, continued to receive tryptophan, while placebo was substituted in the other half under double-blind conditions. In the open phase of the study, there was a clinically and statistically (p less than 0.001) significant reduction in manic symptom scores, with little need for haloperidol prn. Patients who continued to be treated with tryptophan showed no significant change in mean scores during the second week, but those who were switched to placebo tended (p less than 0.10) to show an increase in the mean scores for manic symptoms. There was a significant (p less than 0.05) increase in the geometric mean of morning fasting total and free plasma tryptophan concentrations in men, but not in women. These results suggest that increasing the synthesis of 5-hydroxytryptamine has some therapeutic effect in mania.

Enhancement of the antidepressant action of fluoxetine by folic acid: a randomised, placebo controlled trial.

Coppen A, Bailey J. MRC Neuropsychiatry Laboratory, West Park Hospital, KT19 8PB, Surrey, Epsom, UK.

J Affect Disord 2000 Nov;60(2):121-30

BACKGROUND: A consistent finding in major depression has been a low plasma and red cell folate which has also been linked to poor response to antidepressants. The present investigation was designed to investigate whether the co-administration of folic acid would enhance the antidepressant action of fluoxetine.

METHODS: 127 patients were randomly assigned to receive either 500 microg folic acid or an identical looking placebo in addition to 20 mg fluoxetine daily. All patients met the DSM-III-R criteria for major depression and had a baseline Hamilton Rating Scale (17 item version) score for depression of 20 or more. Baseline and 10-week estimations of plasma folate and homocysteine were carried out.

RESULTS: Patients receiving folate showed a significant increase in plasma folate.This was less in men than in women. Plasma homocysteine was significantly decreased in women by 20.6%, but there was no significant change in men. Overall there was a significantly greater improvement in the fluoxetine plus folic acid group. This was confined to women where the mean Hamilton Rating Scale score on completion was 6.8 (S.D. 4. 1) in the fluoxetine plus folate group, as compared to 11.7 (S.D. 6. 7) in the fluoxetine plus placebo group (< 0.001).A percentage of 93. 9 of women, who received the folic acid supplement, showed a good response (< 50% reduction in score) as compared to 61.1% of women who received placebo supplement (< 0.005). Eight (12.9%) patients in the fluoxetine plus folic acid group reported symptoms possibly or probably related to medication, whereas in the fluoxetine plus placebo group 19 (29.7%) patients reported such symptoms (< 0.05).

LIMITATIONS AND CONCLUSIONS: Folic acid is a simple method of greatly improving the antidepressant action of fluoxetine and probably other antidepressants. Folic acid should be given in doses sufficient to decrease plasma homocysteine. Men require a higher dose of folic acid to achieve this than women, but more work is required to ascertain the optimum dose of folic acid.

We report a pilot study of S-adenosyl-methionine (SAM) in 13 depressed patients with Parkinson's disease. All patients had been previously treated with other antidepressant agents and had no significant benefit or had intolerable side effects. SAM was administered in doses of 800 to 3600 mg per day for a period of 10 weeks. Eleven patients completed the study, and 10 had at least a 50% improvement on the 17-point Hamilton Depression Scale (HDS). One patient did not improve. Two patients prematurely terminated participation in the study because of increased anxiety. One patient experienced mild nausea, and another two patients developed mild diarrhea, which resolved spontaneously. The mean HDS score before treatment was 27.09 +/- 6.04 (mean +/- standard deviation) and was 9.55 +/- 7.29 after SAM treatment (< 0.0001). Although uncontrolled and preliminary, this study suggests that SAM is well tolerated and may be a safe and effective alternative to the antidepressant agents currently used in patients with Parkinson's disease.

Omega-3 polyunsaturated fatty acid levels in the diet and in red blood cell membranes of depressed patients.

Edwards R, Peet M, Shay J, Horrobin D. University Department of Psychiatry, University of Sheffield, UK.

J Affect Disord 1998 Mar;48(2-3):149-55

BACKGROUND: There is a hypothesis that lack of n-3 polyunsaturated fatty acids (PUFAs) is of aetiological importance in depression. Docosahexaenoic acid, a member of the n-3 PUFA family, is a crucial component of synaptic cell membranes. The aim of this study was to measure RBC membrane fatty acids in a group of depressed patients relative to a well matched healthy control group. METHOD: Red blood cell (RBC) membrane levels, and dietary PUFA intake were measured in 10 depressed patients and 14 matched healthy control subjects. RESULTS: There was a significant depletion of RBC membrane n-3 PUFAs in the depressed subjects which was not due to reduced calorie intake. Severity of depression correlated negatively with RBC membrane levels and with dietary intake of n-3 PUFAs. CONCLUSION: Lower RBC membrane n-3 PUFAs are associated with the severity of depression. LIMITATIONS: Although patient numbers were small, confounding factors were well controlled for and the results were highly significant. Results of the dietary data would tend to be weakened due to the limitations associated with dietary assessment. CLINICAL RELEVANCE: The findings raise the possibility that depressive symptoms may be alleviated by n-3 PUFA supplementation.

[Acupuncture in patients with minor depressive episodes and generalized anxiety. Results of an experimental study] [Article in German]

Fortschr Neurol Psychiatr 2000 Mar;68(3):137-44

In a placebo-controlled, randomized, modified double-blind study we investigated the effects of body needle acupuncture (n = 10) in 43 patients with minor depression (ICD 10 F32.0, F32.1) and 13 patients with generalized anxiety disorders (ICD10 F41.1). The severity of the disease was assessed by the Clinical Global Impression Scale (CGI). Treatment response was defined as a significant improvement in CGI. An intent-to-treat analysis was performed to compare treatment responses between verum- and placebo acupuncture. After completing an total of 10 acupuncture sessions the verum acupuncture group (n = 28) showed a significantly larger clinical improvement compared to the placebo group (Mann-Whitney test, < 0.05). There were significantly more responders in the verum-compared to the placebo group (60.7% vs. 21.4%; chi-square test, < 0.01). In contrast, no differences in the response rates were evident just after 5 acupuncture sessions. A multivariate analysis with the independent factor acupuncture (verum vs. placebo) and the results of the results of the additional rating scales (total score of HAMA, HAMD, Bf-S, BL) as dependent variables (ANOVA, 1:54 D.F.) revealed a clear trend towards lower HAMA scores in the verum group after completing 10 acupunctures (F3.29, p = 0.075). This corresponds well to the high response rate of 85.7% in patients with generalized anxiety disorders, in whom verum acupuncture was applied. Our results indicate that needle acupuncture (Du.20, Ex.6, He.7, Pe.6, Bl.62) leads to a significant clinical improvement as well as to a remarkable reduction in anxiety symptoms in patients with minor depression or with generalized anxiety disorders. The total sum of acupuncture sessions and the specific location of acupuncture needle insertions might be important factors for bringing about therapeutic success.

BACKGROUND: Depression is a major cause of morbidity and mortality in children and adolescents. To date, randomized, controlled, double-blind trials of antidepressants (largely tricyclic agents) have yet to reveal that any antidepressant is more effective than placebo. This article is of a randomized, double-blind, placebo-controlled trial of fluoxetine in children and adolescents with depression. METHODS: Ninety-six child and adolescent outpatients (aged 7-17 years) with nonpsychotic major depressive disorder were randomized (stratified for age and sex) to 20 mg of fluoxetine or placebo and seen weekly for 8 consecutive weeks. Randomization was preceded by 3 evaluation visits that included structured diagnostic interviews during 2 weeks, followed 1 week later by a 1-week, single-blind placebo run-in. Primary outcome measurements were the global improvement of the Clinical Global Impressions scale and the Children's Depression Rating Scale--Revised, a measure of the severity depressive symptoms. RESULTS: Of the 96 patients, 48 were randomized to fluoxetine treatment and 48 to placebo. Using the intent to treat sample, 27 (56%) of those receiving fluoxetine and 16 (33%) receiving placebo were rated "much" or "very much" improved on the Clinical Global Impressions scale at study exit (chi 2 = 5.1, df = 1, P = .02). Significant differences were also noted in weekly ratings of the Children's Depression Rating Scale--Revised after 5 weeks of treatment (using last observation carried forward). Equivalent response rates were found for patients aged 12 years and younger (n = 48) and those aged 13 years and older (n = 48). However, complete symptom remission (Children's Depression Rating Scale--Revised < or = 28) occurred in only 31% of the fluoxetine-treated patients and 23% of the placebo patients. CONCLUSION: Fluoxetine was superior to placebo in the acute phase treatment of major depressive disorder in child and adolescent outpatients with severe, persistent depression. Complete remission of symptoms was rare.

Massage therapy effects.

Field TM. Touch Research Institute, University of Miami School of Medicine, FL 33101, USA.

Am Psychol 1998 Dec;53(12):1270-81

Massage therapy is older than recorded time, and rubbing was the primary form of medicine until the pharmaceutical revolution of the 1940s. Popularized again as part of the alternative medicine movement, massage therapy has recently received empirical support for facilitating growth, reducing pain, increasing alertness, diminishing depression, and enhancing immune function. In this article studies are reviewed that document these effects, and models are proposed for potential underlying mechanisms.

Comparison of regimens containing oral micronized progesterone or medroxyprogesterone acetate on quality of life in postmenopausal women: a cross-sectional survey.

Fitzpatrick LA, Pace C, Wiita B. Mayo Clinic and Mayo Foundation, Rochester, Minnesota 55905, USA.

J Womens Health Gend Based Med 2000 May;9(4):381-7

A cross-sectional survey was conducted to examine quality of life (QOL) related to physiological, somatic, and vasomotor effects of changing progestogen treatment from medroxyprogesterone acetate (MPA) to micronized progesterone in postmenopausal women. Eligible women (n = 176) were currently using hormone replacement therapy (HRT) containing micronized progesterone for 1-6 months and had previously received HRT containing MPA. QOL was assessed via telephone interview using the Greene Climacteric Scale and the Women's Health Questionnaire. When compared with the MPA-containing regimen, women using micronized progesterone-containing HRT experienced significant improvement in vasomotor symptoms, somatic complaints, and anxiety and depressive symptoms. Women reported improved perceptions of their patterns of vaginal bleeding and control of menopausal symptoms while on the micronized progesterone-containing regimen. Approximately 80% of women reported overall satisfaction with the micronized progesterone-containing regimen. A micronized progesterone-containing HRT regimen offers the potential for improved QOL as measured by improvement of menopause-associated symptoms.

Fujii A, Matsumoto H, Yamamoto H. Department of Pharmacology, Nihon University School of Dentistry at Matsudo, Chiba, Japan.

Gen Pharmacol 1996 Sep;27(6):995-1000

1. The effect of vitamin B complex (vitamin B1, B6 and B12) was studied on nerve conduction velocity in acrylamide-neuropathy rats maintained on refined semisynthetic complete vitamin and vitamin B-deficient diets in vivo and on neurite outgrowth in vitro using cells obtained from dorsal root ganglions of mice. 2. Acrylamide neuropathy was clearer in the group maintained on a refined semisynthetic vitamin B-deficient diet than in those on a refined semisynthetic complete vitamin diet. The neurotoxicity was lowest in the group given vitamin B complex prophylactic-therapeutically, next higher following therapeutic administration and last with no vitamin B complex administration in both groups maintained on a refined semisynthetic vitamin B-deficient diet and a refined semisynthetic complete vitamin diet. 3. The nerve conduction velocity tended to decrease by treatment with acrylamide. The decrement of nerve conduction velocity was partially inhibited by vitamin B complex. No significant difference was found in the groups treated with acrylamide and given vitamin B complex prophylactic-therapeutically and the control (no acrylamide treatment) in the group maintained on a refined semisynthetic vitamin B-deficient diet. 4. The greatest neurite outgrowth was found in the group treated with vitamins B1, B6 and B12-enriched medium, followed by the group of vitamin B12-enriched and vitamin B1-enriched media. All groups treated with a vitamin B-enriched medium had significantly greater (< 0.01) outgrowth than the controls.

The making of a user friendly MAOI diet.

Gardner DM, Shulman KI, Walker SE, Tailor SA. Department of Pharmacy, Sunnybrook Health Science Centre, University of Toronto, Ontario, Canada.

J Clin Psychiatry 1996 Mar;57(3):99-104

BACKGROUND: Many monoamine oxidase inhibitor (MAOI) diets are considered to be excessively restrictive and founded on poor scientific evidence. We present a safe and practical MAOI diet based on the related clinical and analytic data. METHOD: We used a critical review of the literature and our own tyramine assay results to categorize foods to be restricted absolutely, taken in moderation only, or unrestricted. RESULTS: We recommend that users avoid aged cheese; aged or cured meats (e.g., air-dried sausage); any potentially spoiled meat, poultry, or fish; broad (fava) bean pods; Marmite concentrated yeast extract; sauerkraut; soy sauce and soy bean condiments; and tap beer. Wine and domestic bottled or canned beer are considered safe when consumed in moderation. Other foods not mentioned are considered unrestricted. CONCLUSION: The concerns about perpetuating an overly restrictive MAOI diet include the avoidance by prescribers of a potentially useful treatment option, excessive limitations on lifestyle for patients, and increased risk to patients secondary to noncompliance with the diet. We propose an MAOI diet that has a solid scientific and clinical basis and that is, above all, practical.

St John's wort for depression: a systematic review.

Gaster B, Holroyd J. Department of Medicine, University of Washington, Seattle, USA. barakg@u.washington.edu

Arch Intern Med 2000 Jan 24;160(2):152-6

To address whether St John's wort is useful for the treatment of depression we attempted to retrieve all English-language articles with data on the efficacy, safety, and availability of St John's wort. Randomized, controlled, double-blind trials were selected and assessed for methodological quality using a standardized checklist, and data on pharmacology, cost, regulation, and safety were extracted. Eight studies were identified, found to be of generally good methodological quality, and determined to provide a modest amount of data to suggest that St John's wort is more effective than placebo in the treatment of mild to moderate depression. The absolute increased response rate with the use of St John's wort ranged from 23% to 55% higher than with placebo, but ranged from 6% to 18% lower compared with tricyclic antidepressants. More data are required to assess both its use in severe depression and its efficacy compared with other antidepressants. Rates of side effects were low. As a dietary supplement, St John's wort is currently largely unregulated, but the Food and Drug Administration is reviewing plans to tighten its regulatory oversight.

St. John's Wort extract: efficacy for menopausal symptoms of psychological origin.

Grube B, Walper A, Wheatley D. Lichtwer Pharma AG, Berlin, Germany.

Adv Ther 1999 Jul-Aug;16(4):177-86

Herbal remedies such as St. John's Wort preparations can be used successfully to relieve the psychological and vegetative symptoms of menopause. This drug-monitoring study investigated 12 weeks of treatment with St. John's Wort, one tablet three times daily (900 mg Hypericum, Kira), in 111 women from a general medical practice. The patients, who were between 43 and 65 years old, had climacteric symptoms characteristic of the pre- and postmenopausal state. Treatment outcome was evaluated by the Menopause Rating Scale, a self-designed questionnaire for assessing sexuality, and the Clinical Global Impression scale. The incidence and severity of typical psychological, psychosomatic, and vasomotor symptoms were recorded at baseline and after 5, 8, and 12 weeks of treatment. Substantial improvement in psychological and psychosomatic symptoms was observed. Climacteric complaints diminished or disappeared completely in the majority of women (76.4% by patient evaluation and 79.2% by physician evaluation). Of note, sexual well-being also improved after treatment with St. John's Wort extract.

Arzneimittelforschung 1999 Apr;49(4):289-96

In a randomised double-blind comparative trial, the antidepressant efficacy of a daily dose of 800 mg of the St. John's wort extract LoHyp-57 (dry extract of St. John's wort, drug extrakt ratio 5-7:1, solvent, ethanol 60% [w/w]) was shown to be equivalent to that of 20 mg fluoxetine (CAS 54910-89-3) in elderly patients with mild or moderate depressive episodes according to ICD 10 (International Statistical Classification of Diseases and Related Health Problems). Treatment was given for six weeks. 149 out-patients (129 females and 20 males) were included in the intention-to-treat analysis. 72 of these patients were assigned to the ICD 10 diagnostic criterion F32.0 (mild depressive episode), while 77 patients were suffering from moderate depressive episodes, corresponding to F32.1. The principal target criterion was the patient's global score on the HAMILTON Depression Scale (items 1-17). During the six-week course of treatment with LoHyp-57, the HAMILTON global score fell from 16.60 points at entry to 7.91 points, and in the fluoxetine sample it fell from 17.18 to 8.11 points. In the group of patients with mild depressive episodes, the score showed a mean fall from 14.21 to 6.21 points on LoHyp-57, and from 15.21 to 7.46 points on fluoxetine. In patients with moderate depressive episodes, the score showed a mean fall from 18.73 to 9.43 points on LoHyp-57 and from 19.10 to 8.75 points on fluoxetine. The efficacy of both medications was found to be equivalent both in mild and moderate depressive episodes. Both treatment groups showed adverse drug reactions (ADRs). Twelve ADRs with a possible relationship to the study medication were reported during treatment with LoHyp-57. Six patients were prematurely withdrawn from treatment with the study medication for this reason. On fluoxetine 17 ADRs occurred with a possible relationship to the study medication. These led to abandonment of treatment and therefore premature withdrawal from the study in 8 cases.

Dietary polyunsaturated fatty acids and depression: when cholesterol does not satisfy.

Hibbeln JR, Salem N Jr. Laboratory of Membrane Biophysics and Biochemistry, DICBR, National Institute of Alcohol Abuse and Alcoholism, Rockville, MD 20852, USA.

Am J Clin Nutr 1995 Jul;62(1):1-9

Recent studies have both offered and contested the proposition that lowering plasma cholesterol by diet and medications increases suicide, homicide, and depression. Significant confounding factors include the quantity and distribution of dietary n-6 and n-3 polyunsaturated essential fatty acids that influence serum lipids and alter the biophysical and biochemical properties of cell membranes. Epidemiological studies in various countries and in the United States in the last century suggest that decreased n-3 fatty acid consumption correlates with increasing rates of depression. This is consistent with a well-established positive correlation between depression and coronary artery disease. Long-chain n-3 polyunsaturate deficiency may also contribute to depressive symptoms in alcoholism, multiple sclerosis, and post-partum depression. We postulate that adequate long-chain polyunsaturated fatty acids, particularly docosahexaenoic acid, may reduce the development of depression just as n-3 polyunsaturated fatty acids may reduce coronary artery disease.

Clinical and subclinical hypothyroidism in patients with chronic and treatment-resistant depression.

Hickie I, Bennett B, Mitchell P, Wilhelm K, Orlay W. School of Psychiatry, University of New South Wales, Academic Department of Psychiatry, St George Hospital and Community Service, Kogarah, Australia.

Aust N Z J Psychiatry 1996 Apr;30(2):246-52

OBJECTIVE: To investigate the relationship between hypothyroidism and treatment-resistant depression (TRD). METHOD: A retrospective case audit of 93 inpatients of a specialist Mood Disorders Unit. Patients referred with TRD were sub-classified into 'adequate' or 'inadequate' prior treatment groups on the basis of pre-established criteria, and compared with a 'non-TRD' control sample. Grades I (clinical) and II (subclinical) hypothyroidism were determined by review of relevant thyroid indices. RESULTS: Patients had chronic depressive disorders (sub-group means of 57.5-82.2 weeks of illness). Of those patients referred with TRD, 22% (10/46) had evidence of clinical or subclinical hypothyroidism compared with 2% (1/47) of the non-TRD patients (< 0.01). A gradient in the rates of grade I hypothyroidism was observed with the adequately-treated TRD patients having the highest rate (13%), the inadequately-treated TRD patients having an intermediate rate (7%), and the non-TRD patients having the lowest rate (2%). Consistent with this view, the inadequately-treated TRD group had the highest rate of grade II hypothyroidism (p = 0.01) and tended to have higher thyroid stimulating hormone (TSH) values (p = 0.06). Differences in the rates of hypothyroidism could not be accounted for by differences in age or prior exposure to lithium and/or carbamazepine. Duration of the depressive episode was negatively correlated with both the free thyroxine indices (r = -0.25, < 0.05) and TSH levels (r = -0.32, < 0.01). CONCLUSIONS: This study suggests that relative hypothyroidism may play a role in the development of some treatment-resistant depressive disorders.

The use of androgens in menopause.

Hoeger KM, Guzick DS. University of Rochester, Department of Obstetrics & Gynecology, NY 14642-8668, USA.

Clin Obstet Gynecol 1999 Dec;42(4):883-94

Recent increase in the potential role for androgen supplementation in the menopause, as well as the availability of nontraditional, over-the-counter food supplements containing DHEA, currently touted for postmenopausal health, have raised the need for clinicians to have a working knowledge of both potential benefits and risks of androgen replacement as a supplement to traditional hormone replacement therapy. There is compelling evidence that androgen levels are reduced after bilateral oophorectomy. The degree of androgen reduction after natural menopause may be less, and the onset of this decrease more gradual in this population. A decrease in androgen levels has been proposed as one etiology for decreased libido, and there is some evidence to support androgen use in oophorectomized women suffering from diminished libido. Such evidence is mixed, however, in naturally menopausal women. Androgen replacement may provide additional relief of menopausal symptoms in some patients, but this evidence is also inconsistent. Initial studies seem to support a perceived enhancement in psychological well-being, but confirmatory, long-term studies are still needed. Available evidence suggests a positive impact on bone density with the use of some androgen preparations, but no consistent benefit from DHEA has been demonstrated. Although androgen therapy can induce decreases in HDL cholesterol levels, the clinical impact of this is not yet known. Currently, there is little support for the routine use of androgen supplementation in the menopause. Additionally, a number of adverse events may be associated with androgen use. Careful patient selection, with comprehensive evaluation to sort out other possible medical or psychological conditions, should be undertaken before the initiation of androgen replacement. Currently available preparations are limited in number and flexibility in dosing, but there is ongoing effort to develop new delivery systems and therapeutics so that options available in the future may allow for enhanced availability and efficacy.

Decreased cerebral 5-HT1A receptors during ageing: reversal by Ginkgo biloba extract (EGb 761).

Huguet F, Drieu K, Piriou A. Institut des Xenobiotiques, Faculte de Medecine et de Pharmacie, Poitiers, France.

J Pharm Pharmacol 1994 Apr;46(4):316-8

Investigation of [3H]8-hydroxy-2(di-n-propylamino)tetralin binding to 5-HT1A receptors in cerebral cortex membranes of Wistar rats showed that the maximal number of binding sites (Bmax) was reduced significantly (22%) in aged (24-month-old) as compared with young (4-month-old) animals. Chronic treatment with Ginkgo biloba extract did not alter binding in young rats but increased binding density significantly (33%) in aged rats. These results confirm previously described age-related 5-hydroxytryptaminergic alterations. Together with data in the literature, they also suggest a restorative effect in aged rats, associated with decreased receptor density resulting from the protective action of Ginkgo biloba extract treatment on neuronal membrane.

Improvement in mood and fatigue after dehydroepiandrosterone replacement in Addison's disease in a randomized, double blind trial.

Hunt PJ, Gurnell EM, Huppert FA, Richards C, Prevost AT, Wass JA, Herbert J, Chatterjee VK. Department of Endocrinology, University of Oxford, Radcliffe Infirmary, Oxford, United Kingdom.

J Clin Endocrinol Metab 2000 Dec;85(12):4650-6

Dehydroepiandrosterone (DHEA) and DHEA sulfate (DHEAS) are adrenal precursors of steroid biosynthesis and centrally acting neurosteroids. Glucocorticoid and ineralocorticoid deficiencies in Addison's disease require life-long hormone replacement, but the associated failure of DHEA synthesis is not corrected. We conducted a randomized, double blind study in which 39 patients with Addison's disease received either 50 mg oral DHEA daily for 12 weeks, followed by a 4-week washout period, then 12 weeks of placebo, or vice versa. After DHEA treatment, levels of DHEAS and Delta(4)-androstenedione rose from subnormal to within the adult physiological range. Total testosterone increased from subnormal to low normal with a fall in serum sex hormone-binding globulin in females, but with no change in either parameter in males. In both sexes, psychological assessment showed significant enhancement of self-esteem with a tendency for improved overall well-being. Mood and fatigue also improved significantly, with benefit being evident in the evenings. No effects on cognitive or sexual function, body composition, lipids, or bone mineral density were observed. Our results indicate that DHEA replacement corrects this steroid deficiency effectively and improves some aspects of psychological function. Beneficial effects in males, independent of circulating testosterone levels, suggest that it may act directly on the central nervous system rather than by augmenting peripheral androgen biosynthesis. These positive effects, in the absence of significant adverse events, suggest a role for DHEA replacement therapy in the treatment of Addison's disease.

Effect of acute and chronic administration of dehydroepiandrosterone on (+/-)-1-(2,5-dimethoxy-4-iodophenyl)-2-aminopropane-induced wet dog shaking behavior in rats.

Inagaki M, Kagaya A, Takebayashi M, Horiguchi J, Yamawaki S. Department of Psychiatry and Neurosciences, Hiroshima University School of Medicine, Japan.

J Neural Transm 1999;106(1):23-33

It has been reported that dehydroepiandrosterone (DHEA) or dehydroepiandrosterone sulfate (DHEA-S) is associated with affective disorders and that pathology of affective disorders are related with dysfunction of serotonin(5-HT)-2A receptor-mediated responses. In this study, we investigated the effect of DHEA on (+/-)-1-(2,5-dimethoxy-4-iodophenyl)-2 aminopropane (DOI), 5-HT-2A receptor agonist, -induced wet dog shaking behavior (WDS) in rats. Acute treatment with DHEA inhibited the DOI-induced WDSs dose dependently. This inhibition was recovered by opioid receptor antagonist, naltrexone. 5-HT-2A receptor-mediated WDSs were desensitized after chronic treatment with DOI, however chronic treatment with DHEA had no effect on this desensitization. Chronic treatment with DHEA had no facilitating effect of chronic dexamethasone treatment on DOI-induced WDSs. These findings may lead the possibility that DHEA has the inhibitory effect of 5-HT-2A mediated signaling pathway via non-genomic action.

Antidepressant efficacy of Sudarshan Kriya Yoga (SKY) in melancholia: a randomized comparison with electroconvulsive therapy (ECT) and imipramine.

J Affect Disord 2000 Jan-Mar;57(1-3):255-9

BACKGROUND: Sudarshan Kriya Yoga (SKY) is a procedure that involves essentially rhythmic hyperventilation at different rates of breathing. The antidepressant efficacy of SKY was demonstrated in dysthymia in a prospective, open clinical trial. This study compared the relative antidepressant efficacy of SKY in melancholia with two of the current standard treatments, electroconvulsive therapy (ECT) and imipramine (IMN). METHODS: Consenting, untreated melancholic depressives (n=45) were hospitalized and randomized equally into three treatment groups. They were assessed at recruitment and weekly thereafter for four weeks. RESULTS: Significant reductions in the total scores on Beck Depression Inventory (BDI) and Hamilton Rating Scale for Depression (HRSD) occurred on successive occasions in all three groups. The groups, however, did not differ. Significant interaction between the groups and occasion of assessment occurred. At week three, the SKY group had higher scores than the ECT group but was not different from the IMN group. Remission (total HRSD score of seven or less) rates at the end of the trial were 93, 73 and 67% in the ECT, IMN and SKY groups, respectively. No clinically significant side effects were observed. DISCUSSION: Within the limitations of the design (lack of double blind conditions), it can be concluded that, although inferior to ECT, SKY can be a potential alternative to drugs in melancholia as a first line treatment.

Treatment of seasonal affective disorder (SAD) with hypericum extract.

Kasper S. Department of General Psychiatry, University of Vienna, Austria.

Pharmacopsychiatry 1997 Sep;30 Suppl 2:89-93

Seasonal affective disorder (SAD) is a subgroup of major depression and characterized by a regular occurrence of symptoms in autumn/winter and full remission or hypomania in spring/summer. Light therapy (LT) and recently pharmacotherapy with specific antidepressants have been shown to be beneficial. Within the array of pharmacotherapy hypericum extract has also been found to be effective in a single-blind study (Martinez et al., 1994). In this 4 weeks treatment study 900 mg of hypericum was associated with a significant reduction in the total score of the Hamilton Depression Rating Scale. There was no significant difference when bright light therapy was combined with hypericum, compared to the situation without bright light therapy. Overall, hypericum was well tolerated and therefore the data suggest that pharmacological treatment with hypericum may be an efficient therapy in patients with SAD, which needs to be substantiated in further controlled studies.

A comparison of nefazodone, the cognitive behavioral-analysis system of psychotherapy, and their combination for the treatment of chronic depression.

Keller MB, McCullough JP, Klein DN, Arnow B, Dunner DL, Gelenberg AJ, Markowitz JC, Nemeroff CB, Russell JM, Thase ME, Trivedi MH, Zajecka J. Department of Psychiatry, Brown University, Providence, RI 02906, USA.

N Engl J Med 2000 May 18;342(20):1462-70

BACKGROUND: Patients with chronic forms of major depression are difficult to treat, and the relative efficacy of medications and psychotherapy is uncertain.

METHODS: We randomly assigned 681 adults with a chronic nonpsychotic major depressive disorder to 12 weeks of outpatient treatment with nefazodone (maximal dose, 600 mg per day), the cognitive behavioral-analysis system of psychotherapy (16 to 20 sessions), or both. At base line, all patients had scores of at least 20 on the 24-item Hamilton Rating Scale for Depression (indicating clinically significant depression). Remission was defined as a score of 8 or less at weeks 10 and 12. For patients who did not have remission, a satisfactory response was defined as a reduction in the score by at least 50 percent from base line and a score of 15 or less. Raters were unaware of the patients' treatment assignments.

RESULTS: Of the 681 patients, 662 attended at least one treatment session and were included in the analysis of response. The overall rate of response (both remission and satisfactory response) was 48 percent in both the nefazodone group and in the psychotherapy group, as compared with 73 percent in the combined-treatment group. (< 0.001 for both comparisons). Among the 519 subjects who completed the study, the rates of response were 55 percent in the nefazodone group and 52 percent in the psychotherapy group, as compared with 85 percent in the combined-treatment group (< 0.001 for both comparisons). The rates of withdrawal were similar in the three groups. Adverse events in the nefazodone group were consistent with the known side effects of the drug (e.g., headache, somnolence, dry mouth, nausea, and dizziness).

CONCLUSIONS: Although about half of patients with chronic forms of major depression have a response to short-term treatment with either nefazodone or a cognitive behavioral-analysis system of psychotherapy, the combination of the two is significantly more efficacious than either treatment alone.

Folates: supplemental forms and therapeutic applications.

Kelly GS. gregnd@worldnet.att.net

Altern Med Rev 1998 Jun;3(3):208-20

Folates function as a single carbon donor in the synthesis of serine from glycine, in the synthesis of nucleotides form purine precursors, indirectly in the synthesis of transfer RNA, and as a methyl donor to create methylcobalamin, which is used in the re-methylation of homocysteine to methionine. Oral folates are generally available in two supplemental forms, folic and folinic acid. Administration of folinic acid bypasses the deconjugation and reduction steps required for folic acid. Folinic acid also appears to be a more metabolically active form of folate, capable of boosting levels of the coenzyme forms of the vitamin in circumstances where folic acid has little to no effect. Therapeutically, folic acid can reduce homocysteine levels and the occurrence of neural tube defects, might play a role in preventing cervical dysplasia and protecting against neoplasia in ulcerative colitis, appears to be a rational aspect of a nutritional protocol to treat vitiligo, and can increase the resistance of the gingiva to local irritants, leading to a reduction in inflammation. Reports also indicate that neuropsychiatric diseases secondary to folate deficiency might include dementia, schizophrenia-like syndromes, insomnia, irritability, forgetfulness, endogenous depression, organic psychosis, peripheral neuropathy, myelopathy, and restless legs syndrome.

Psychopharmacology (Berl) 1998 Feb;135(4):319-23

Mood changes synchronised to the seasons exist on a continuum between individuals, with anxiety and depression increasing during the winter months. An extreme form of seasonality is manifested as the clinical syndrome of seasonal affective disorder (SAD) with carbohydrate craving, hypersomnia, lethargy, and changes in circadian rhythms also evident. It has been suggested that seasonality and the symptoms of SAD may be due to changing levels of vitamin D3, the hormone of sunlight, leading to changes in brain serotonin. Forty-four healthy subjects were given 400 IU, 800 IU, or no vitamin D3 for 5 days during late winter in a random double-blind study. Results on a self-report measure showed that vitamin D3 significantly enhanced positive affect and there was some evidence of a reduction in negative affect. Results are discussed in terms of their implications for seasonality, SAD, serotonin, food preference, sleep, and circadian rhythms.

Controlled trials of inositol in psychiatry.

Eur Neuropsychopharmacol 1997 May;7(2):147-55

Inositol is a simple polyol precursor in a second messenger system important in the brain. Cerebrospinal fluid inositol has been reported as decreased in depression. A double-blind controlled trial of 12 g daily of inositol in 28 depressed patients for four weeks was performed. Significant overall benefit for inositol compared to placebo was found at week 4 on the Hamilton Depression Scale. No changes were noted in hematology, kidney or liver function. Since many antidepressants are effective in panic disorder, twenty-one patients with panic disorder with or without agoraphobia completed a double-blind, placebo-controlled, four week, random-assignment crossover treatment trial of inositol 12 g per day. Frequency and severity of panic attacks and severity of agoraphobia declined significantly with inositol compared to placebo. Side-effects were minimal. Since serotonin re-uptake inhibitors benefit obsessive compulsive disorder (OCD) and inositol is reported to reverse desensitization of serotonin receptors, thirteen patients with OCD completed a double-blind controlled crossover trial of 18 g inositol or placebo for six weeks each. Inositol significantly reduced scores of OCD symptoms compared with placebo. A controlled double-blind crossover trial of 12 g daily of inositol for a month in twelve anergic schizophrenic patients, did not show any beneficial effects. A double-blind controlled crossover trial of 6 g of inositol daily vs. glucose for one month each was carried out in eleven Alzheimer patients, with on clearly significant therapeutic effects. Antidepressant drugs have been reported to improve attention deficit disorder (ADDH) with hyperactivity symptomatology. We studied oral inositol in children with ADDH in a double-blind, crossover, placebo-controlled manner. Eleven children, mean age 8.9 +/- 3.6 years were enrolled in an eight week trial of inositol or placebo at a dose of 200 mg/kg body weight. Results show a trend for aggravation of the syndrome with myo-inositol as compared to placebo. Recent studies suggest that serotonin re-uptake inhibitors are helpful in at least some symptoms of autism. However a controlled double-blind crossover trial of inositol 200 mg/kg per day showed no benefit in nine children with autism. Cholinergic agonists have been reported to ameliorate electroconvulsive therapy (ECT)-induced memory impairment. Inositol metabolism is involved in the second messenger system for several muscarinic cholinergic receptors. Inositol 6 g daily was given in a crossover-double-blind manner for five days before the fifth or sixth ECT to a series of twelve patients, without effect. These results suggest that inositol has therapeutic effects in the spectrum of illness responsive to serotonin selective re-uptake inhibitors, including depression, panic and OCD, and is not beneficial in schizophrenia, Alzheimer's ADDH, autism or ECT-induced cognitive impairment.

Am J Psychiatry 1995 May;152(5):792-4

OBJECTIVE: CSF levels of inositol have been reported to be lower than normal in depressed subjects. The authors administered inositol to depressed patients in a double-blind, controlled trial. METHOD: Under double-blind conditions, 12 g/day of inositol (N = 13) or placebo (N = 15) was administered to depressed patients for 4 weeks. RESULTS: The overall improvement in scores on the Hamilton Depression Rating Scale was significantly greater for inositol than for placebo at week 4. No changes were noted in hematology or in kidney or liver function. CONCLUSIONS: This may be the first use of the precursor strategy for a second messenger rather than a neurotransmitter in treating depression. Although inositol had a significant antidepressant effect in this study, replication is crucial.

A recent controlled double-blind study of 28 patients treated with 12 gm daily of inositol or placebo revealed significant antidepressant effect for this second messenger precursor. Patients were followed-up by interview and Hamilton Depression Scale 10-12 months after the end of the study. Half of the patients who had responded well to inositol relapsed rapidly after inositol discontinuation whereas none of those who responded to placebo relapsed rapidly after placebo cessation. Klein suggested that true drug responders to tricyclic antidepressants respond slowly and gradually whereas placebo responders improve early in an abrupt fashion. However, in the recent study both inositol and placebo responders improved at similar rates. Hamilton Depression Scale Scores 10-12 months after completion of the study were not significantly different between those who had responded and those who had not responded to inositol or to placebo.

BMJ 1996 Aug 3;313(7052):253-8

OBJECTIVE--To investigate if extracts of Hypericum perforatum (St John's wort) are more effective than placebo in the treatment of depression, are as effective as standard antidepressive treatment, and have fewer side effects than standard antidepressant drugs. DESIGN-Systematic review and meta-analysis of trials revealed by searches. TRIALS--23 randomised trials including a total of 1757 outpatients with mainly mild or moderately severe depressive disorders: 15 (14 testing single preparations and one a combination with other plant extracts) were placebo controlled, and eight (six testing single preparations and two combinations) compared hypericum with another drug treatment. MAIN OUTCOME MEASURES--A pooled estimate of the responder rate ratio (responder rate in treatment group/responder rate in control group), and numbers of patients reporting and dropping out for side effects. RESULTS--Hypericum extracts were significantly superior to placebo (ratio = 2.67; 95% confidence interval 1.78 to 4.01) and similarly effective as standard antidepressants (single preparations 1.10; 0.93 to 1.31, combinations 1.52; 0.78 to 2.94). There were two (0.8%) drop outs for side effects with hypericum and seven (3.0%) with standard antidepressant drugs. Side effects occurred in 50 (19.8%) patients on hypericum and 84 (52.8%) patients on standard antidepressants. CONCLUSION--There is evidence that extracts of hypericum are more effective than placebo for the treatment of mild to moderately severe depressive disorders. Further studies comparing extracts with standard antidepressants in well defined groups of patients and comparing different extracts and doses are needed.

Acta Psychiatr Scand 1999 Jul;100(1):62-6

OBJECTIVE: The aim was to test the hypothesis that the Ginkgo biloba extract PN246, in tablet form (brand name Bio-Biloba), may prevent the symptoms of winter depression (WD) in patients with seasonal affective disorder (SAD). METHOD: A total of 27 SAD patients were randomized to receive double-blind placebo or Bio-Biloba for 10 weeks or until they developed symptoms of WD, starting in a symptom-free phase about 1 month before expected WD symptoms. An extended Montgomery-Asberg Depression Rating Scale was completed before and immediately after termination of medication. The patients also self-rated some key symptoms on a visual analogue scale every 2 weeks during the trial. RESULTS: There were no significant differences between the treatment groups in the number of patients who developed treatment-requiring WD, or in the development of single key symptoms during the trial. CONCLUSION: We did not find that Ginkgo biloba was able to prevent the development of the symptoms of winter depression.

How does stress affect you? An overview of stress, immunity, depression and disease.

Maddock C, Pariante CM.

Maudsley Hospital, London SE5 8AZ, UK.

Epidemiol Psichiatr Soc 2001 Jul-Sep;10(3):153-62

OBJECTIVE: Stress is a term that has become synonymous with modern life. This review aims to appraise the evidence linking stress with disease with particular reference to the major causes of morbidity and mortality in the Western World, cardiovascular disease, cancer, and depression. Changes in immune parameters in stressful situations were reviewed as a possible pathophysiological mechanism for such effects.

METHOD: A Medline search was carried out for the period 1996-2000 to identify recent findings in this field using the terms "stress", "disease", "immune system". Relevant references that were found in all identified publications were also followed up.

RESULTS: There is evidence to link stress with the onset of major depression and with a poorer prognosis in cardiovascular disease and cancer. Few small studies suggest that stress management strategies may help to improve survival. Chronic stress appears to result in suppression of the immune response, whereas immune activation and suppression have been associated with acute stress. Inflammatory cytokines, soluble mediators of the immune response, can result in symptoms of depression.

CONCLUSION: Further prospective epidemiologically based studies are needed to clarify the role of stress on disease onset, course, and prognosis. Stress management strategies, aimed at prolonging survival in patients with cardiovascular disease, cancer, and possibly other chronic illnesses, are an exciting area of further research. Immune system changes may account for the relationship between stress and disease. We propose the "stress, cytokine, depression" model as a biological pathway to explain the link between stressful life events and depression.

The effects of the herb St. John's wort (Hypericum perforatum), a purported antidepressant, on the activity of cytochrome P-450 (CYP) 2D6 and 3A4 was assessed in seven normal volunteers. Probe substrates dextromethorphan (2D6 activity) and alprazolam (3A4 activity) were administered orally with and without the co-administration of St. John's wort. Urinary concentrations of dextromethorphan and dextrorphan were quantified and dextromethorphan metabolic ratios (DMRs) determined. Plasma samples were collected (0-60 hrs) for alprazolam pharmacokinetic analysis sufficient to estimate tmax, Cmax, t 1/2, and AUC. Validated HPLC methods were used to quantify all compounds of interest. No statistically significant differences were found in any estimated pharmacokinetic parameter for alprazolam or DMRs. These results suggest that St. John's wort, when taken at recommended doses for depression, is unlikely to inhibit CYP 2D6 or CYP 3A4 activity.

Comparing aerobic with nonaerobic forms of exercise in the treatment of clinical depression: a randomized trial.

Compr Psychiatry 1989 Jul-Aug;30(4):324-31

We compared aerobic with nonaerobic forms of exercise in the treatment of clinical depression. Ninety-nine inpatients, who met the DMS-III-R criteria for major depression, dysthymic disorder, or depressive disorder not otherwise specified (NOS), took part in the study. They were randomly assigned to two different physical training conditions, aerobic and nonaerobic. In both conditions, one hour of training was performed three times a week for a period of 8 weeks. There was a significant increase in maximum oxygen uptake (VO2 max) in the aerobic group; there was no change in the nonaerobic group regarding this variable. Depression scores in both groups were significantly reduced during the study, but there was no significant difference between the groups. The correlation between increase in physical fitness and reduction in depression scores was low. The study indicates that the antidepressive effects associated with exercises are not restricted to aerobic forms of training.

We investigated the effects of egg phosphatidylcholine (PC) combined with vitamin B12 on memory in the Morris water maze task, and on choline and acetylcholine (ACh) concentrations in the brain of rats. Animals with nucleus basalis Magnocellularis (NBM) lesion received intragastric administration of egg PC or vitamin B12, or both for 18 days. Memory acquisition and retention were remarkably impaired in NBM lesioned rats compared with in sham-operated control. NBM lesioned group had lower choline and ACh concentrations than control group in the frontal cortex. High dose of egg PC alone significantly increased choline concentration, but did not change ACh concentration in the frontal cortex. High dose of vitamin B12 alone did not change choline and ACh concentrations in the brain. Either egg PC or vitamin B12 did not improve memory acquisition and retention. However, low dose of egg PC combined with vitamin B12 significantly increased ACh concentration and improved memory acquisition and retention in the NBM lesioned rats. We concluded that egg PC combined with vitamin B12 improved the memory impairment of NBM lesioned rats through the action on the cholinergic neurons.

Fatal malignant hyperthermia as a result of ingestion of tranylcypromine (Parnate) combined with white wine and cheese.

Mirchandani H, Reich LE.

J Forensic Sci 1985 Jan;30(1):217-20

Fatal malignant hyperthermia occurred in a patient who was taking tranylcypromine (Parnate) and ingested wine and cheese. The case findings are presented along with a review of the literature concerning adverse interactions between monoamine oxidase (MAO) inhibitors and certain foods and beverages. Hyperthermia and its possible causative mechanisms and treatments are discussed. The facts suggest that the complicated dietary restrictions attending the use of MAO inhibitors and the possibility of severe and even catastrophic reactions resulting from violations of these restrictions make the use of these drugs fraught with danger and therefore not a first choice for the treatment of depression.

Direct effects of estrogens on the endocrine function of the mammalian testis.

Moger WH.

Can J Physiol Pharmacol 1980 Sep;58(9):1011-22

This article reviews literature relevant to the view that estradiol (E2) synthesized in the testis acts locally to modify testosterone secretion. Despite a lack of convincing evidence from in vitro experiments, in vivo experiments with intact and hypophysectomized animals have demonstrated that estrogens can inhibit testosterone secretion by acting directly on the testis. Reduced testosterone production in estrogen-treated animals probably results from reduced 17 alpha-hydroxylase and (or) C17-C20 lyase activity. Estrogen-inhibited steroidogenesis may result from estrogen binding to high affinity--low capacity estrogen receptors. Besides being an estrogen target tissue, the testis produces E2; the cellular site of testicular E2 synthesis remains controversial. Recent studies indicate that E2 is synthesized primarily in the Sertoli cells of neonatal rats and in the Leydig cells of older rats. Follicle-stimulating hormone and human chorionic gonadotropin (hCG) increase testicular aromatase activity and E2 concentrations in neonatal and older rats, respectively. An increase in testicular E2 concentrations, following hCG administration, may be one mechanism by which testosterone synthesis becomes desensitized to subsequent hCG stimulation. However, whether gonadotropin-stimulated testicular E2 synthesis is part of a physiologically relevant "short" feedback loop that participates in the regulation of testosterone synthesis remains to be determined.

Evaluation of the relative potency of individual competing amino acids to tryptophan transport in endogenously depressed patients.

Moller, Svend E.

Psychiatry Research 3(2):141-150, 1980

The relative potency of the individual amino acids as competitive inhibitors of tryptophan transport into the human brain was evaluated retrospectively; the combination of competitors that yields the highest predictive value of the plasma tryptophan ratio for the course of treatment of depressed patients with L-tryptophan was also examined. Phenylalanine consistently reduced, and isoleucine slightly reduced the predictive value of the plasma tryptophan ratio. The ratio of tryptophan to the sum of valine, leucine, and tyrosine was identified as most predictive for the therapeutic response to tryptophan. L-tryptophan responders showed a normal plasma total tryptophan concentration as did the nonresponders, whereas the concentration of the three competitors was significantly elevated. It is concluded that while the plasma ratio of tryptophan to the sum of valine, leucine, and tyrosine is a useful predictor of the course of depressives on L-tryptophan, it does not definitely separate out the L-tryptophan responders from the control subjects.

Relationship between plasma ratio of tryptophan to competing amino acids and the response to L-tryptophan treatment in endogenously depressed patients.

Moller SE, Kirk L, Honore P.

J Affect Disord 1980 Mar;2(1):47-59

The ratio of the plasma of total tryptophan to those amino acids that compete with tryptophan during transport into the brain was determined in 60 control subjects and 87 patients suffering from endogenous depression, all females. The plasma ratio in the control subjects showed a significant negative correlation with age. There was no significant difference in the distribution of the biochemical data between the control subjects and the depressed patients. There was a significant higher proportion of bipolar depressed subjects compared to unipolar depressives and patients of uncertain polarity who showed a plasma ratio in the lower normal range. Thirty-two patients were subsequently treated with L-tryptophan. In the patients who showed a particularly low plasma ratio of tryptophan to competing amino acids a remission frequency of 80% was observed on day 14. The efficacy of L-tryptophan in the patients who showed a plasma ratio within the upper normal range was extremely poor. The results suggest that the ratio in the plasma of tryptophan to competing amino acids is a useful predictor of the course of treatment of depressed subjects with L-tryptophan.

St. John's wort (Hypericum perforatum) is an herbal remedy used widely for the treatment of depression. Recent clinical studies demonstrate that hypericum extracts increase the metabolism of various drugs, including combined oral contraceptives, cyclosporin, and indinavir. In this report, we show that hyperforin, a constituent of St. John's wort with antidepressant activity, is a potent ligand (K(i) = 27 nM) for the pregnane X receptor, an orphan nuclear receptor that regulates expression of the cytochrome P450 (CYP) 3A4 monooxygenase. Treatment of primary human hepatocytes with hypericum extracts or hyperforin results in a marked induction of CYP3A4 expression. Because CYP3A4 is involved in the oxidative metabolism of >50% of all drugs, our findings provide a molecular mechanism for the interaction of St. John's wort with drugs and suggest that hypericum extracts are likely to interact with many more drugs than previously had been realized.

The effect of six months treatment with a 100 mg daily dose of dehydroepiandrosterone (DHEA) on circulating sex steroids, body composition and muscle strength in age-advanced men and women.

Clin Endocrinol (Oxf) 1998 Oct;49(4):421-32

OBJECTIVE: The biological role of the adrenal sex steroid precursors--DHEA and DHEA sulphate (DS) and their decline with ageing remains undefined. We observed previously that administration of a 50 daily dose of DHEA for 3 months to age-advanced men and women resulted in an elevation (10%) of serum levels of insulin-like growth factor-I (IGF-I) accompanied by improvement of self-reported physical and psychological well-being. These findings led us to assess the effect of a larger dose (100 mg) of DHEA for a longer duration (6 months) on circulating sex steroids, body composition (DEXA) and muscle strength (MedX).

SUBJECTS AND DESIGN: Healthy non-obese age-advanced (50-65 yrs of age) men (n = 9) and women (n = 10) were randomized into a double-blind placebo-controlled cross-over trial. Sixteen subjects completed the one-year study of six months of placebo and six months of 100 mg oral DHEA daily.

MEASUREMENTS: Fasting early morning blood samples were obtained. Serum DHEA, DS, sex steroids, IGF-I, IGFBP-1, IGFBP-3, growth hormone binding protein (GHBP) levels and lipid profiles as well as body composition (by DEXA) and muscle strength (by MedX testing) were measured at baseline and after each treatment.

RESULTS: Basal serum levels of DHEA, DS, androsternedione (A), testosterone (T) and dihydrotestosterone (DHT) were at or below the lower range of young adult levels. In both sexes, a 100 mg daily dose of DHEA restored serum DHEA levels to those of young adults and serum DS to levels at or slightly above the young adult range. Serum cortisol levels were unaltered, consequently the DS/cortisol ratio was increased to pubertal (10:1) levels. In women, but not in men, serum A, T and DHT were increased to levels above gender-specific young adult ranges. Basal SHBG levels were in the normal range for men and elevated in women, of whom 7 of 8 were on oestrogen replacement therapy. While on DHEA, serum SHBG levels declined with a greater (P < 0.02) response in women (-40 +/- 8%; P = 0.002) than in men (-5 +/- 4%; P = 0.02). Relative to baseline, DHEA administration resulted in an elevation of serum IGF-I levels in men (16 +/- 6%, P = 0.04) and in women (31 +/- 12%, P = 0.02). Serum levels of IGFBP-1 and IGFBP-3 were unaltered but GHBP levels declined in women (28 +/- 6%; P = 0.02) not in men. In men, but not in women, fat body mass decreased 1.0 +/- 0.4 kg (6.1 +/- 2.6%, P = 0.02) and knee muscle strength 15.0 +/- 3.3% (P = 0.02) as well as lumbar back strength 13.9 +/- 5.4% (P = 0.01) increased. In women, but not in men, an increase in total body mass of 1.4 +/- 0.4 kg (2.1 +/- 0.7%; P = 0.02) was noted. Neither gender had changes in basal metabolic rate, bone mineral density, urinary pyridinoline cross-links, fasting insulin, glucose, cortisol levels or lipid profiles. No significant adverse effects were observed.

CONCLUSIONS: A daily oral 100 mg dose of DHEA for 6 months resulted in elevation of circulating DHEA and DS concentrations and the DS/cortisol ratio. Biotransformation to potent androgens near and slightly above the range of their younger counterparts occurred in women with no detectable change in men. Given this hormonal milieu, an increase in serum IGF-I levels was observed in both genders but dimorphic responses

were evident in fat body mass and muscle strength in favour of men. These differences in

response to DHEA administration may reflect a gender specific response to DHEA and/or the presence of confounding factor(s) in women such as oestrogen replacement therapy.

Tryptophan depletion and risk of depression relapse: a prospective study of tryptophan depletion as a potential predictor of depressive episodes.

Biol Psychiatry 2000 Aug 15;48(4):327-9

BACKGROUND: This study investigated the relationship between depressive symptom

response during tryptophan depletion and future depressive episodes. METHODS: Twelve subjects with prior major depressive episodes in remission and medication-free for > or =3 months (patients), and 12 matched healthy (control) subjects received two tryptophan depletion tests 1 week apart. During follow-up the Hamilton Depression Rating Scale was administered weekly for 1 month, monthly for 3 months, and once at 6 and 12 months. RESULTS: With results from both tests, tryptophan depletion has a sensitivity of 78%, specificity of 80%, positive predictive value of 70%, and negative predictive value of 86% to identify future depressive episodes. Survival analysis shows that mood response to tryptophan depletion reliably predicts major depressive episodes during the follow-up year (r =.2725, p =.014). CONCLUSIONS: Tryptophan depletion may be clinically useful in identifying individuals at risk for future major depressive episodes.

Outcomes of seven treatment trials comparing cognitive behavioral therapy to treatment with tricyclic antidepressant medication in major depressive disorder have been quite similar to one another. This led us to question whether treatment outcome in time-limited studies reflected a unique effect of cognitive behavioral therapy. To test the uniqueness hypothesis, relaxation training, a nonpharmacologic, noncognitive treatment, was chosen as a comparison for cognitive behavioral therapy as well as drug therapy. Treatment duration was 16 weeks. The sample of 37 patients treated for major depressive disorder was less depressed than those previously studied. For both cognitive behavioral therapy and relaxation training, outcome of depression was superior to that of tricyclic antidepressant medication by endpoint analysis. The posttreatment scores on the Beck Depression Inventory of 82% of the group receiving cognitive behavioral therapy improved to a Beck Depression Inventory score < or = 9 which was not significantly greater than that for the group receiving relaxation training (73%), so a unique effect was not demonstrated for cognitive behavioral therapy. The outcome for tricyclic antidepressant medication (29% improved to criteria) was significantly worse than that for cognitive behavioral therapy. The patient's pretreatment initial expectancy was not predictive.

Physical activity and mental health: current concepts.

Physical activity may play an important role in the management of mild-to-moderate mental health diseases, especially depression and anxiety. Although people with depression tend to be less physically active than non-depressed individuals, increased aerobic exercise or strength training has been shown to reduce depressive symptoms significantly. However, habitual physical activity has not been shown to prevent the onset of depression. Anxiety symptoms and panic disorder also improve with regular exercise, and beneficial effects appear to equal meditation or relaxation. In general, acute anxiety responds better to exercise than chronic anxiety. Studies of older adults and adolescents with depression or anxiety have been limited, but physical activity appears beneficial to these populations as well. Excessive physical activity may lead to overtraining and generate psychological symptoms that mimic depression. Several differing psychological and physiological mechanisms have been proposed to explain the effect of physical activity on mental health disorders. Well controlled studies are needed to clarify the mental health benefits of exercise among various populations and to address directly processes underlying the benefits of exercise on mental health.

J Clin Psychopharmacol 1999 Feb;19(1):19-27

This study was designed to evaluate the safety and effectiveness of testosterone therapy for clinical symptoms of hypogonadism (low libido, low mood, low energy, loss of appetite/weight) in human immunodeficiency virus-positive men with CD4 cell counts less than 400 cells/mm3 and deficient or low normal serum testosterone levels. The trial consisted of 8 weeks of open treatment with 400 mg of intramuscular testosterone cypionate biweekly. Responders were maintained at this dosage for another 4 weeks and then were randomized in a double-blind, placebo-controlled, 6-week discontinuation trial. Of the 112 men who completed at least 8 weeks of treatment, 102 (91%) were rated as responders on a global assessment of sexual desire/function. Of the 34 study completers with major depressive disorder and/or dysthymia, 79% reported significant improvement in mood at week 8. Average weight change was a gain of 3.7 pounds, with 45% gaining more than 5 pounds. Eighty-four men entered and 77 completed the double-blind phase; of these, 78% of completers randomized to testosterone and 13% randomized to placebo maintained their response. No significant medical or immunologic adverse effects were identified. Testosterone therapy was well tolerated and effective in ameliorating symptoms of clinical hypogonadism, and equally so for men with and without testosterone deficiency. For patients with major depression and/or dysthymia, improvement was equal to that achieved with standard antidepressants.

This article reviews evidence that shows a bidirectional relationship between the brain and the immune system. As a result of this relationship, mental factors such as stress and depression have been shown to affect immune system functioning, with both immunosuppression and immune activation being reported. Stress and depression also have been associated with worse outcomes in immune-related disorders including cancer and infectious diseases suggesting that stress/depression effects on the immune system are clinically relevant to disease expression. Conversely, several lines of evidence suggest that immune system activation such as during infectious diseases, cancer, and autoimmune disorders is associated with the development of behavioral symptoms similar to those seen in the context of chronic stress or major depression. These findings implicate a role for the immune system in the cause of behavioral disorders in a wide range of medical illnesses. Finally, a paradigm is proposed in which abnormal functioning of either the hypothalamic-pituitary-adrenal (HPA) axis or the inflammatory response system disrupts feedback regulation of both neuroendocrine and immune systems contributing to the development of neuropsychiatric and immunologic disorders.

Dehydroepiandrosterone (DHEA) and DHEA sulfate (DHEA-S) are secreted primarily by the adrenal glands. DHEA could also be a neuroactive steroidal hormone. Because basal levels of DHEA and DHEA-S in humans decrease significantly with age, these hormones have been assumed to be involved in the aging process and in a number of pathologies which develop with aging: immunosenescence, increased mortality, increased incidence of cancer, osteoporosis and cardiovascular diseases. However, its role is still unknown. In humans, cross sectional and longitudinal studies have shown that DHEA might be associated with global measures of well-being and functioning, but positive effects on measures of memory and attention could not be found. Studies investigating DHEA and DHEA-S levels in dementia have produced controversial results. Short-term experimental studies have not shown significant improvement in global measures of well-being and functioning in healthy subjects but have revealed preliminary evidence for mood enhancing and antidepressant effects of DHEA. There is no evidence that DHEA could induce addiction in human beings.

BACKGROUND: In a single-blind placebo-controlled study design we investigated the

efficacy of acupuncture additionally applied to drug treatment in major depression.

METHODS: We randomly included 70 inpatients with a major depressive episode in three different treatment groups: verum acupuncture, placebo acupuncture and a control group All three groups were pharmacologically treated with the antidepressant mianserin. The verum group received acupuncture at specific points considered effective in the treatment of depression. The placebo group was treated with acupuncture at non-specific locations and the control group received pharmacological treatment plus clinical management. Acupuncture was applied three times a week over a period of 4 weeks. Psychopathology was rated by judges blind to verum/placebo conditions twice a week over 8 weeks. RESULTS: Patients who experienced acupuncture improved slightly more than patients treated with mianserin alone. CONCLUSIONS: Additionally applied acupuncture improved the course of depression more than pharmacological treatment with mianserin alone. However, we could not detect any differences between placebo and verum acupuncture.

S-adenosyl-L-methionine (SAMe) is a naturally occurring substance which is a major source of methyl groups in the brain and has been found in previous studies to be an effective antidepressant. The aim of this study was to assess the efficacy of oral SAMe in the treatment of depressed postmenopausal women in a 30-day double-blind placebo-controlled randomized trial. During the course of the study, 80 women, between the ages of 45 and 59, who were diagnosed as having DSM-III-R major depressive disorder or dysthymia between 6 and 36 months following either natural menopause or hysterectomy, underwent 1 week of single-blind placebo washout, followed by 30 days of double-blind treatment with either SAMe 1,600 mg/day or placebo. There was a significantly greater improvement in depressive symptoms in the group treated with SAMe compared to the placebo group from day 10 of the study. Side effects were mild and transient.

Plasma vitamin C concentrations in patients in a psychiatric hospital.

Schorah CJ, Morgan DB, Hullin RP.

Hum Nutr Clin Nutr 1983 Dec;37(6):447-52

Plasma vitamin C was measured in 885 patients in a psychiatric hospital and in 110 healthy controls. The average value was lower in the patients (0.51 mg/100 ml) than in the controls (0.87 mg/100 ml). Length of stay in hospital had little effect on plasma vitamin C in the patients, but the values were marginally lower in males, females on iron therapy and in those with senile dementia. In the patients, many of whom had been offered a similar diet for several years, age was not associated with a change in plasma vitamin C and this suggests that changes in vitamin C with age that have been reported reflect differences in intake. Few patients had values as low as those found in clinical scurvy (less than 0.1 mg/100 ml), but many (32 per cent) had concentrations below the threshold (0.35 mg/100 ml) at which some detrimental effects on health have been reported.

Equivalence of St John's wort extract (Ze 117) and fluoxetine: a randomized, controlled study in mild-moderate depression.

Int Clin Psychopharmacol 2000 Mar;15(2):61-8

Treatment with St John's wort extract tablets (hypericum Ze 117) and the commonly used slow serotonin reuptake inhibitor (SSRI) fluoxetine was compared in patients with mild-moderate depression with entry Hamilton Depression Scale (HAM-D) (21-item) in the range 16-24, in a randomized, double-blind, parallel group comparison in 240 subjects; fluoxetine: 114 (48%), hypericum: 126 (52%). After 6 weeks' treatment, mean HAM-D at endpoint decreased to 11.54 on hypericum and to 12.20 on fluoxetine (P < 0.09), while mean Clinical Global Impression (CGI) item I (severity) was significantly (P < 0.03) superior on hypericum, as was the responder rate (P = 0.005). Hypericum safety was substantially superior to fluoxetine, with the incidence of adverse events being 23% on fluoxetine and 8% on hypericum. The commonest events on fluoxetine were agitation (8%), GI disturbances (6%), retching (4%), dizziness (4%), tiredness, anxiety/nervousness and erectile dysfunction (3% each), while on hypericum only GI disturbances (5%) had an incidence greater than 2%. We concluded that hypericum and fluoxetine are equipotent with respect to all main parameters used to investigate antidepressants in this population. Although hypericum may be superior in improving the responder rate, the main difference between the two treatments is safety. Hypericum was superior to fluoxetine in overall incidence of side-effects, number of patients with side-effects and the type of side-effect reported.

OBJECTIVE: Previous studies of sex hormone concentrations in depression yielded

inconsistent results. However, the activation of the hypothalamic-pituitary-adrenal system seen in depression may negatively affect gonadal function at every level of regulation. The objective of this study was to explore whether major depressive episodes are indeed associated with an alteration of gonadal function. METHODS: Testosterone, pulsatile LH secretion, FSH, and cortisol were assessed using frequent sampling during a 24-hour period in 15 male inpatients with major depression of moderate to high severity and in 22 healthy comparison subjects (age range 22-85 years). RESULTS: An analysis of covariance model showed that after adjustment for age only, daytime testosterone (p < .01), nighttime testosterone (p < .05), and 24-hour mean testosterone secretion (p < .01) were significantly lower in the depressed male inpatients. There was also a trend for a decreased LH pulse frequency in the depressed patients (p < .08). CONCLUSIONS: Gonadal function may be disturbed in men with a depressive episode of moderate to high severity.

PURPOSE/OBJECTIVES: To evaluate the effects of 10 weeks of aerobic exercise on depressive and anxiety symptoms and self-esteem of breast cancer survivors.

DESIGN: Experimental, crossover. SETTING: Midwestern university town. SAMPLE: Twenty-four breast cancer survivors (mean time following surgery 41.8 months; ranging from 1 to 99 months) recruited via mail and cancer support groups. The mean age of the sample was 48.9 years. METHODS: Subjects were assigned randomly into exercise (EX), exercise-plus-behavior modification (EX + BM), and control groups. EX and EX + BM groups exercised aerobically four days/week at > or = 60% of age-predicted maximum heart rate for 10 weeks. Data were collected pretest, post-test, and crossover (12 weeks following post-test). Because pretest or post-test scores showed no statistical differences between EX and EX + BM groups, data were combined to form one group. MAIN RESEARCH VARIABLES: Aerobic exercise (four days/ week; 30-40 minutes/session), depression, (Beck Depression inventory), anxiety (Speilberger State-Trait Anxiety Inventory), and self-esteem (Rosenberg Self-Esteem Inventory). FINDINGS: Pre- to post-test analyses revealed that women who exercised had significantly less depression and state and trait anxiety over time compared to controls. After the crossover, the control group demonstrated comparable improvements in both depressive and state anxiety scores. Self-esteem did not change significantly. Subjects who received exercise recommendations from their physicians exercised significantly more than subjects who received no recommendation. CONCLUSIONS: Mild to moderate aerobic exercise may be of therapeutic value to breast cancer survivors with respect to depressive and anxiety symptoms but not to self-esteem. A physician's recommendation to exercise appears to be an important factor in a patient's exercise adherence. IMPLICATIONS FOR NURSING PRACTICE: To Improve depressive and anxiety symptoms following breast cancer surgery, healthcare professionals should consider recommending mild to moderate exercise.

Testosterone and depression in aging men.

In men, testosterone secretion affects neurobehavioral functions such as sexual arousal, aggression, emotional tone, and cognition. Beginning at approximately age 50, men secrete progressively lower amounts of testosterone; about 20% of men over age 60 have lower-than-normal levels. The psychiatric sequelae are poorly understood, yet there is evidence of an association with depressive symptoms. The authors reviewed 1) the physiology of the hypothalamic-pituitary-gonadal axis and its changes with age in men; and 2) the evidence linking testosterone level and major depression in men. Data on this relationship are derived from two types of studies: observational studies comparing testosterone levels and secretory patterns in depressed and non-depressed men, and treatment studies using exogenous androgens for male depression. The data suggest that some depressed older men may have state-dependent low testosterone levels and that some depressed men may improve with androgen treatment.

We studied the course of depressive symptoms during an 18-month naturalistic follow-up period for outpatients with Major Depressive Disorder treated in the National Institute of Mental Health Treatment of Depression Collaborative Research Program. The treatment phase consisted of 16 weeks of randomly assigned treatment with the following: cognitive behavior therapy, interpersonal therapy, imipramine hydrochloride plus clinical management (CM), or placebo plus CM. Follow-up assessments were conducted at 6, 12, and 18 months after treatment. Of all patients entering treatment and having follow-up data, the percent who recovered (8 weeks of minimal or no symptoms following the end of treatment) and remained well during follow-up (no Major Depressive Disorder relapse) did not differ significantly among the four treatments: 30% (14/46) for those in the cognitive behavior therapy group, 26% (14/53) for those in the interpersonal therapy group, 19% (9/48) for those in the imipramine plus CM group, and 20% (10/51) for those in the placebo plus CM group. Among patients who had recovered, rates of Major Depressive Disorder relapse were 36% (8/22) for those in the cognitive behavior therapy group, 33% (7/21) for those in the interpersonal therapy group, 50% (9/18) for those in the imipramine plus CM group, and 33% (5/15) for those in the placebo plus CM group. The major finding of this study is that 16 weeks of these specific forms of treatment is insufficient for most patients to achieve full recovery and lasting remission. Future research should be directed at improving success rates of initial and maintenance treatments for depression.

This study investigated the impact that meditation has on Fordyce's (1977, 1983) Personal Happiness Enhancement Program (PHEP). Experimental subjects were divided into two groups, both of which received instruction on the PHEP. Subjects in one experimental group were taught a meditation exercise in addition to the PHEP. A control group received no instruction. The Happiness Measure, Psychap Inventory, Beck Depression Inventory, and State-Trait Anxiety Scale were dependent measures. The three (groups) x two (pre-post) mixed ANOVAs with Student Newman-Keuls found that the meditation plus PHEP group significantly improved on all dependent measures over both the PHEP only group and the control group. The PHEP only group improved significantly over the control group on all measures except state anxiety.

BACKGROUND: Omega3 fatty acids may inhibit neuronal signal transduction pathways in a manner similar to that of lithium carbonate and valproate, 2 effective treatments for bipolar disorder. The present study was performed to examine whether omega3 fatty acids also exhibit mood-stabilizing properties in bipolar disorder. METHODS: A 4-month, double-blind, placebo-controlled study, comparing omega3 fatty acids (9.6 g/d) vs placebo (olive oil), in addition to usual treatment, in 30 patients with bipolar disorder. RESULTS: A Kaplan-Meier survival analysis of the cohort found that the omega3 fatty acid patient group had a significantly longer period of remission than the placebo group (P = .002; Mantel-Cox). In addition, for nearly every other outcome measure, the omega3 fatty acid group performed better than the placebo group. CONCLUSION: Omega3 fatty acids were well tolerated and improved the short-term course of illness in this preliminary study of patients with bipolar disorder.

Diet and monoamine oxidase inhibitors: a re-examination.

Sullivan EA, Shulman KI.

Can J Psychiatry 1984 Dec;29(8):707-11

Monoamine oxidase inhibitors (MAOIs) are attracting renewed attention as effective antidepressants for refractory depressions, particularly among the elderly. However, widespread fears concerning the interactions of MAOIs with tyramine-containing foods have led to the development of long and complicated diets. These diets have served as an obstacle to the ready use of MAOIs, yet very little systematic or critical review of the basis for food restriction has been undertaken. An international survey of MAOI diets was conducted and from the diets collected, foods were categorized according to frequency of restriction on the diet lists. On the basis of this survey and a critical review of the literature it was determined that only four foods clearly warrant absolute prohibition: aged cheese, pickled fish (herring), concentrated yeast extracts and broad bean pods. While there is insufficient evidence to prohibit alcohol completely (even chianti wine) true moderation must apply. It is suggested that a radically simplified diet should be investigated on a prospective basis.

The aim of this double-blind randomized study was to compare the efficacy and the tolerability of moclobemide (300-600 mg daily) and pirlindole (150-300 mg daily), two reversible inhibitors of MAO-A (RIMAs), in the treatment of depression. In total 116 patients were included in the trial, 111 patients (52 patients on pirlindole and 59 patients on moclobemide) were evaluable for efficacy and safety, and 77 patients completed the whole study (42 days of administration). Both treatments produced highly significant improvements in the Hamilton Depression Rating Scale (HDRS) score, the Hamilton Anxiety Rating Scale (HARS) score and the Montgomery-Asberg Rating Scale MADRS) score from day 7 to day 42. The pattern of development of the three scores in the two groups did not differ significantly. After 42 days of treatment, an improvement of > or = 50% in the HDRS score was noted in 80% and 67% of patients in the pirlindole and moclobemide groups, respectively. A total of 30 (58%) patients on pirlindole and 33 (56%) patients on moclobemide experienced side-effects that were considered to be possibly or probably related to the medication. The differences between the two drugs were non-significant for all types of side-effect, with the exception of dry mouth and tachycardia, which were significantly more frequent with moclobemide.

OBJECTIVE: This report compares response to cognitive-behavioral therapy (CBT) and pharmacotherapy in sequential cohorts of men with DSM-III-R major depression. METHOD: Patients were enrolled in consecutive standardized 16-week treatment protocols conducted in the same research clinic. The first group (N = 52) was treated with Beck's model of CBT, whereas the second group (N = 23) received randomized but open-label treatment with either fluoxetine (N = 10) or bupropion (N = 13). Crossover to the alternate medication was permitted after 8 weeks of treatment for antidepressant nonresponders. The patient groups were well matched prior to treatment. Outcomes

included remission and nonresponse rates, as well as both independent clinical evaluations and self-reported measures of depressive symptoms. RESULTS: Despite limited statistical power to detect differences between treatments, depressed men treated with pharmacotherapy had significantly greater improvements on 4 of 6 continuous dependent measures and a significantly lower rate of nonresponse (i.e., 13% vs. 46%). The difference favoring pharmacotherapy was late-emerging and partially explained by crossing over nonresponders to the alternate medication. The advantage of pharmacotherapy over CBT also tended to be larger among the subgroup of patients with chronic depression. CONCLUSION: Results of prior research comparing pharmacotherapy and CBT may have been influenced by the composition of study groups, particularly the gender composition, the choice of antidepressant comparators, or an interaction of these factors. Prospective studies utilizing flexible dosing of modern antidepressants and, if necessary, sequential trials of dissimilar medications are needed to confirm these findings.

OBJECTIVE: To evaluate the degree of psychological dysfunction and levels of stress hormones in postmenopausal women with climacteric syndromes and effect of Korean red ginseng (RG) on them. METHODS: ACTH, cortisol and DHEA-S in peripheral blood from 12 postmenopausal women with climacteric syndromes or 8 postmenopausal women

without any climacteric syndrome were measured before and 30 days after treatment with daily oral administration of 6 g RG. Blood samples were collected in the early morning on the bed-rest. In postmenopausal women with climacteric syndromes such as fatigue, insomnia and depression, psychological tests using the Cornell Medical Index (CMI) and the State-Trait Anxiety Inventory (STAI) were performed before and 30 days after treatment with RG. RESULTS: CMI score as well as anxiety (A)-state in STAI score in postmenopausal women with climacteric syndromes was significantly higher than that without climacteric syndrome, while DHEA-S levels in postmenopausal women with

climacteric syndromes were about a half of those without climacteric syndrome. Consequently, cortisol/DHEA-S (C/D) ratio was significantly higher in postmenopausal women with climacteric syndromes than in those without climacteric syndrome. When postmenopausal women with climacteric syndromes were treated with daily oral administration of 6 g RG for 30 days, CMI and STAI A-state scores decreased within normal range. Although the decreased DHEA-S levels were not restored to the levels in postmenopausal women without climacteric syndrome, the C/D ratio decreased significantly after treatment with RG. CONCLUSIONS: Improvement of CMI and STAI scores in postmenopausal women suffering climacteric syndromes, particularly fatigue, insomnia and depression, by RG seemed to be brought about in part by effects of RG on stress-related hormones as shown by a decrease in C/D ratio.

1. Ninety psychiatric inpatients with a DSM III diagnosis of schizophrenia, mania, or major depression were studied. 2. Upon admission/transfer to the Clinical Studies Unit, and prior to discharge, measurements of symptom severity (BPRS, Ham-D, Young's Mania Scale) and blood samples were obtained. 3. Erythrocytes from these paired (admission and discharge) blood samples were assayed for methionine adenosyltransferase (MAT) activity and phosphatidylcholine (PC) content. 4. Comparisons were made between the changes in MAT Vmax, or % PC, and changes in symptom severity. 5. For the majority of the patients (79.3% of the schizophrenics; 84.6% of the depressives; and 93.8% of the manics), clinical improvement was associated with a "normalization" of enzyme activity. The association between changes in % PC and clinical response did not achieve significant correlation.

Pharmacopsychiatry 1997 Sep;30 Suppl 2:81-5

The special extract of St. John's wort, LI 160, exhibited a superior antidepressant efficacy compared to placebo in several controlled trials. Two further trials demonstrated a similar reduction of depressive symptomatology under LI 160 compared to tricyclics. All these trials were performed in mildly to moderately depressed patients. The present investigation was a randomized, controlled, multicentre, 6-week trial comparing 1800 mg LI 160/die to 150 mg imipramine/die in severely depressed patients according to ICD-10. The main efficacy parameter, a reduction of the total score of the Hamilton Depression Scale, proved both treatment regimens very effective at the end of the 6 week treatment period (mean values 25.3 to 14.5 in the LI 160 group and 26.1 to 13.6 in the imipramine group), but not statistically equivalent within a a-priori defined 25% interval of deviation. The analysis of subgroups with more than a 33% and 50% reduction of the HAMD total score justified the assumption of equivalence within a 25% deviation interval. This view was also supported by the global efficacy ratings from patients and investigators. Regarding adverse events, the nonrejection of the nonequivalence hypothesis denotes a superiority of the herbal antidepressant. These main result indicate that LI 160 might be a treatment alternative to the synthetic tricyclic antidepressant imipramine in the majority of severe forms of depressions. However, more studies of this type must be performed before a stronger recommendation can be made.

Patient compliance with MAO inhibitor therapy.

Walker JI, Davidson J, Zung WW.

J Clin Psychiatry 1984 Jul;45(7 Pt 2):78-80

Exaggerated fears of monoamine oxidase inhibitors (MAOIs) and of their interactions with foods often restrict their use. A review of the literature reveals seven food items most likely to produce a hypertensive crisis in combination with MAOI administration: aged cheeses, smoked or pickled fish, beef or chicken liver, dry fermented sausage, pods of broad beans, brewer's yeast products, and certain alcoholic beverages. Improved understanding of the dietary restrictions, benefits, and mechanism of action of the MAOIs can enhance cooperation with the prescribed treatment program.

A randomized, multicenter, double-blind, parallel group study was performed to assess the effects of a standardized ginseng extract compared with those of a placebo on quality of life (QoL) and on physiological parameters in symptomatic postmenopausal women. Validated questionnaires [Psychological General Well-Being (PGWB) index, Women's Health Questionnaire (WHQ)] and Visual Analogue (VA) scales were used to assess the effects of the extract on QoL at baseline and after 16 weeks' treatment with either the ginseng extract or placebo. To assess the efficacy of ginseng on postmenopausal symptoms, physiological parameters [follicle-stimulating hormone (FSH) and estradiol levels, endometrial thickness, maturity index and vaginal pH] were recorded at the same time points. Of the 384 randomized patients (mean age 53.5 +/- 4.0 years), the questionnaires were completed by 193 women treated with ginseng and 191 treated with placebo. With regard to the primary endpoint (total score of the PGWB index) the extract showed only a tendency for a slightly better overall symptomatic relief (p < 0.1). Exploratory analysis of PGWB subsets, however, reported p-values < 0.05 for depression, well-being and health subscales in favor of ginseng compared with placebo. No statistically significant effects were seen for the WHQ and the VA scales or the physiological parameters, including vasomotor symptoms (hot flushes). The positive effects of ginseng on health-related QoL in menopausal women should be further investigated. This study shows, however, that the beneficial effects of ginseng are most likely not mediated by hormone replacement-like effects, as physiological parameters such as FSH and estradiol levels, endometrial thickness, maturity index and vaginal pH were not affected by the treatment.

OBJECTIVES: To compare the efficacy and tolerability of Hypericum perforatum (St John's wort extract) with imipramine in patients with mild to moderate depression. DESIGN: Randomised, multicentre, double blind, parallel group trial. SETTING: 40 outpatient clinics in Germany. Participants: 324 outpatients with mild to moderate depression. INTERVENTION: 75 mg imipramine twice daily or 250 mg hypericum extract ZE 117 twice daily for 6 weeks. MAIN OUTCOME MEASURES: Hamilton depression rating scale, clinical global impression scale, and patient's global impression scale. RESULTS: Among the 157 participants taking hypericum mean scores on the Hamilton depression scale decreased from 22.4 at baseline to 12.00 at end point; among the 167 participants taking imipramine they fell from 22.1 to 12.75. Mean clinical global impression scores at end point were 2.22 out of 7 for the hypericum group and 2.42 for the imipramine group. On the 7 point self assessments of global improvement completed by participants (score of 1 indicating "very much improved" and 7 indicating "very much deteriorated") mean scores were 2.44 in the hypericum group and 2.60 in the imipramine group. None of the differences between treatment groups were significant. However, the mean score on the anxiety-somatisation subscale of the Hamilton scale (3.79 in the hypericum group and 4.26 in the imipramine group) indicated a significant advantage for hypericum relative to imipramine. Mean scores on the 5 point scale used by participants to assess tolerability (score of 1 indicating excellent tolerability and 5 indicating very poor tolerability) were better for hypericum (1.67) than imipramine (2.35). Adverse events occurred in 62/157 (39%) participants taking hypericum and in 105/167 (63%) taking imipramine. 4 (3%) participants taking hypericum withdrew because of adverse events compared with 26 (16%) taking imipramine. CONCLUSIONS: This Hypericum perforatum extract is therapeutically equivalent to imipramine in treating mild to moderate depression, but patients tolerate hypericum better.

Dehydroepiandrosterone (DHEA) and its sulfate, DHEA-S, are plentiful adrenal steroid hormones that decrease with aging and may have significant neuropsychiatric effects. In this study, six middle-aged and elderly patients with major depression and low basalplasma DHEA f1p4or DHEA-S levels were openly administered DHEA (30-90 mg/d x 4weeks) in doses sufficient to achieve circulating plasma levels observed in younger healthy individuals. Depression ratings, as well as aspects of memory performance significantly improved. One treatment-resistant patient received extended treatment with DHEA for 6 months: her depression ratings improved 48-72% and her semantic memory performance improved 63%. These measures returned to baseline after treatment ended. In both studies, improvements in depression ratings and memory performance were directly related to increases in plasma levels of DHEA and DHEA-S and to increases in their ratios with plasma cortisol levels. These preliminary data suggest DHEA may haveantidepressant and promemory effects and should encourage double-blind trials indepressed patients.

OBJECTIVE: This study was designed to assess possible antidepressant effects of dehydroepiandrosterone (DHEA), an abundant adrenocortical hormone in humans.

METHOD: Twenty-two patients with major depression, either medication-free or on stabilized antidepressant regimens, received either DHEA (maximum dose = 90 mg/day) or placebo for 6 weeks in a double-blind manner and were rated at baseline and at the end of the 6 weeks with the Hamilton Depression Rating Scale. Patients previously stabilized with antidepressants had the study medication added to that regimen; others received DHEA or placebo alone.|

RESULTS: DHEA was associated with a significantly greater decrease in Hamilton depression scale ratings than was placebo. Five of the 11 patients treated with DHEA, compared with none of the 11 given placebo, showed a 50% decrease or greater in depressive symptoms.

CONCLUSIONS: These results suggest that DHEA treatment may have significant antidepressant effects in some patients with major depression. Further, larger-scale trials are warranted.

DHEA in appropriate replacement doses appears to have remedial effects with respect to its ability to induce an anabolic growth factor, increase muscle strength and lean body mass, activate immune function, and enhance quality of life in aging men and women, with no significant adverse effects. Further studies are needed to confirm and extend our current results, particularly the gender differences.

The use of diet and dietary components in the study of factors controllingaffect in humans: a review.

Although one of the first biological treatments of a major psychiatric disorder was the dietary treatment of pellagra, the use of diet and dietary components in the study of psychopathology has not aroused much interest. This article reviews three areas in which the dietary approach has provided interesting information. The tryptophan depletion strategy uses a mixture of amino acids devoid of tryptophan to lower brain tryptophan in order to study the symptoms that can be elicited. One effect of tryptophan depletion is a lowering of mood, the magnitude of which seems to depend on the baseline state of the subject. Therefore, recovered depressed patients often undergo an acute relapse, while normal subjects show more moderate changes of mood. Totally euthymic subjects show no lowering of mood, but subjects with high normal depression scale scores or subjects with a family history of depression show a moderate lowering of mood. These data indicate that low serotonin levels alone cannot cause depression. However, serotonin does have a direct effect on mood, and low levels of serotonin contribute to the etiology of depression in some depressed patients. Folic acid deficiency causes a lowering of brain serotonin in rats, and of cerebrospinal fluid 5-hydroxyindoleacetic acid in humans. There is a high incidence of folate deficiency in depression, and there are indications in the literature that some depressed patients who are folate deficient respond to folate administration. Folate deficiency is known to lower levels of S-adenosylmethionine, and S-adenosylmethionine is an antidepressant that raises brain serotonin levels. These data suggest that low levels of serotonin in some depressed patients may be a secondary consequence of low levels of S-adenosylmethionine. They also suggest that the dietary intake and psychopharmacological action of methionine, the precursor of S-adenosylmethionine, should be studied in patients with depression. Normal meals have definite effects on mood and performance in humans. The composition of the meal, in terms of protein and carbohydrate content, can influence these behaviors. Because protein and carbohydrate meals can influence brain serotonin in rats, these effects in humans have usually been interpreted in terms of altered serotonin functioning. However, the current balance of evidence is against the involvement of serotonin in the acute effects of protein and carbohydrate meals in humans. The underlying mechanisms involved are unknown, but there are a variety of possibilities.(ABSTRACT TRUNCATED AT 400 WORDS)

1. The incidence of folic acid deficiency is high in patients with various psychiatric isorders including depression, dementia and schizophrenia. 2. In epileptics on anticonvulsants, folate deficiency often occurs because anticonvulsants inhibit folate absorption. In these patients folate deficiency is often associated with psychiatric symptoms. 3. In medical patients psychiatric symptoms occur more frequently, and in psychiatric patients symptoms are more severe, in those with folate deficiency than in those with normal levels. 4. Many open studies have demonstrated therapeutic effects of folate administration on psychiatric symptoms in folate deficient patients. 5. Several placebo-controlled studies have not demonstrated therapeutic effects, possibly because the doses they used (15-20 mg/day) are known to be toxic and to cause mental symptoms. 6. Two placebo-controlled studies have demonstrated beneficial effects of folic acid administration, one in patients with a syndrome of psychiatric and neuropsychological changes associated with folate deficiency and the other in patients on long-term lithium therapy. In the latter study the dose was only 0.2 mg/day. 7. Folic acid deficiency is known to lower brain S-adenosylmethionine and 5-hydroxytryptamine. S-Adenosylmethionine, which has antidepressant properties, raises brain 5-hydroxytryptamine. Thus, depression associated with folate deficiency is probably related to low brain 5HT. 8. S-Adenosylmethionine is involved in many methylation reactions, including methylation of membrane phospholipids, which influences membrane properties. This may explain the wide variety of symptoms associated with folate deficiency. 9. Because the costs and risks associated with low doses of folic acid (up to 0.5 mg/day) are small, folic acid should be given as an adjunct in the treatment of patients with unipolar or bipolar affective disorders and anorexia, epileptics on anticonvulsants, geriatric patients with mental symptoms and patients with gastrointestinal disorders who exhibit psychiatric symptoms. 10. Although the majority of the patients listed above will probably not be helped by folic acid therapy, a significant minority are likely to have folate-responsive symptoms.

In a previous study we demonstrated the ability of dopamine (DA) to stimulate phospholipid methylation (PLM) via a novel mechanism involving the D4 dopamine receptor (D4R) in which single-carbon folates appeared to be the primary source of methyl groups. To further understand the relationship between D4R-mediated PLM and folate metabolism, we examined the effect of several folate pathway interventions on the level of basal and DA-stimulated incorporation of [14C]-labeled formate into phospholipids in cultured SH-SY5Y neuroblastoma cells. These interventions included: (i) Overexpression of methenyltetrahydrofolate synthetase (MTHFS). (ii) Treatment with 5-formylTHF. (iii) Treatment with the MTHFS inhibitor 5-formyltetrahydrohomofolic acid (5-formylTHHF). (iv) Growth in nucleoside-free media. 31P-NMR was also used to follow DA-induced changes in cell phospholipid composition. MTHFS overexpression and 5-formylTHHF treatment, both of which lower 5-methylTHF levels, each reduced basal PLM and its stimulation by DA. In contrast, 5-formylTHF, which increases 5-methylTHF, caused a dose-dependent increase in both basal and DA-stimulated PLM. Growth in nucleoside-free media caused time-dependent changes in PLM, which were due to the absence of purine nucleosides. While basal PLM was maintained at a reduced level, DA-stimulated PLM was initially increased followed by a later decrease. Together, these findings indicate a close functional relationship between single-carbon folate metabolism and DA-stimulated PLM, consistent with a role for 5-methylTHF as the methyl donor for the D4R-mediated process.
