Our studies indicate that colchicine appears to
halt the progression of PSS, and probably of the
localized forms of scleroderma as well, and causes
improvement in a substantial proportion of
patients. Such improvement takes place mainly in
the skin and has been significant enough to be
corroborated by the histological examination of
skin biopsies evaluated without knowledge of the
clinical situation. Some improvement has also
occurred at sites of involvement other than the
skin, particularly in regard to dysphagia and
Raynaud's phenomenon. The nature of our study did
not allow us to determine if treatment with
colchicine may prevent the development of renal or
lung involvement. Patients who were begun on
treatment with colchicine earlier in the course of
their disease had significantly greater
improvement than those who were first treated
after disease of longer duration. Long-term
treatment appeared to be required as evaluated by
the correlation between improvement and total
colchicine dose received. The apparent innocuity
of long-term treatment with colchicine and the
beneficial effects which have been observed
warrant the use of this agent in the treatment of
PSS. Early and prolonged use appear particularly
desirable.

PURPOSE: The ingestion of omega -3 fatty acids
could benefit patients with Raynaud's phenomenon
because, among other effects, these fatty acids
induce a favorable vascular response to ischemia.
The aim of our study was to investigate, in a
double-blind, placebo-controlled manner, the
effects of fish - oil fatty-acid dietary therapy
in patients with rheumatic disease.
PATIENTS AND METHODS: Thirty-two patients with
primary or secondary Raynaud's phenomenon were
randomly assigned to olive-oil placebo or fish -
oil groups. Patients ingested 12 fish -oil
capsules daily containing a total of 3.96 g
eicosapentaenoic acid and 2.64 g docosahexaenoic
acid or 12 olive-oil capsules and were evaluated
at baseline and after six, 12, and 17 weeks. All
patients ingested olive oil between Weeks 12 to
17. Digital systolic blood pressures and blood
flow were measured at room air and water baths of
40 degrees C, 25 degrees C, 15 degrees C, and 10
degrees C using strain gauge plethysmography.
Onset of Raynaud's phenomenon was timed with a
stop watch and defined as plethysmographic
evidence of cessation of blood flow and blood
pressure in the study finger.
RESULTS: In the fish -oil group, the median
time interval before the onset of Raynaud's
phenomenon increased from 31.3 +/- 1.3 minutes
baseline to 46.5 +/- 2.1 minutes at six weeks (p =
0.04). Patients with primary Raynaud's phenomenon
ingesting fish oil had the greatest increase in
the time interval before the onset of the
condition. Five of 11 patients (45.5 percent) with
primary Raynaud's phenomenon ingesting fish oil in
whom the phenomenon was induced at baseline could
not be induced to develop Raynaud's at the six- or
12-week visit compared with one of nine patients
(11 percent) with primary Raynaud's ingesting
olive oil (p = 0.05). The mean digital systolic
pressures were higher in the patients with primary
Raynaud's phenomenon ingesting fish oil than in
patients with primary Raynaud's ingesting olive
oil in the 10 degrees C water bath (+32 mm Hg, p =
0.02).
CONCLUSION: We conclude that the ingestion of
fish oil improves tolerance to cold exposure and
delays the onset of vasospasm in patients with
primary, but not secondary, Raynaud's phenomenon.
These improvements are associated with
significantly increased digital systolic blood
pressures in cold temperatures.

Demographic and survival data are presented for
390 patients with scleroderma . For the entire
group an estimated 81.4% survived 5 years from
diagnosis and 69.4% survived 10 years. Life-table
analyses revealed that adequate treatment with
potassium para-aminobenzoate (Potaba KPAB) was
associated with improved survival (p less than
0.01); 88.5% 5 year survival rate and 76.6% 10
year survival rate for adequately treated
patients. Five and ten year survival rates for
patients never treated with KPAB were 69.8 and
56.6%, respectively. Similar findings were
obtained by comparing observed to expected
mortality for these patients; again, KPAB therapy
showed prolongation of survival. The Cox
proportional hazards model was also applied to
this retrospective study adjusting for baseline
clinical involvement, demographics and KPAB
treatment. There were some interesting results
including a high significance for skin involvement
per se as a prognostic indicator: the greater the
extent of skin involvement the poorer prognosis.
Time from first diagnosis to first University
Hospital visit or admission when included as a
covariate did not influence survival.
Lipodermatosclerosis is characterized
by elevated expression and activation of matrix
metalloproteinases: implications for venous ulcer

Lipodermatosclerosis refers to skin induration
of the lower extremities and is associated with
patients preceding venous ulcerations. To better
understand the pathogenesis of ulcer formation we
investigated the expression of matrix
metalloproteinases (MMP) and tissue inhibitors of
metalloproteinases (TIMP) in lipodermatosclerosis.
By preparing biopsies from healthy skin and
liposclerotic lesions, MMP-1, MMP-2, MMP-9,
TIMP-1, and TIMP-2 were analyzed by using reverse
transcriptase-polymerase chain reaction, western
blot, zymography, hydrolysis of [3H]labeled
collagens, and immunohistochemistry. Our
investigations provide evidence that mRNA and
protein expression of MMP-1, MMP-2, and TIMP-1
were significantly increased in
lipodermatosclerosis, whereas the total amount of
MMP-9 and TIMP-2 mRNA and protein was not altered.
Western blot of liposclerotic lesions revealed an
inactive proMMP-1-TIMP-1 complex, whereas MMP-2
was prominent as an active 66 kDa band. Increased
proteolytic activity of MMP-2 could be proven in
lesional in comparison with healthy skin by
zymography and [3H] collagen degradation.
Increased diffuse staining was found for MMP-1 in
the epidermis and dermis in comparison with
controls. In lipodermatosclerosis, MMP-2 was
predominantly localized in the basal and
suprabasal layers of the epidermis, in
perivascular regions, and in the reticular part of
the dermis. Furthermore, MMP-2 was imbalanced by
locally reduced expression of TIMP-2 in the
basement membrane zone of lesional skin. Our
findings indicate lipodermatosclerosis to be
characterized by elevated matrix turnover.
Pathogenesis of scleroderma (systemic
sclerosis).
LeRoy EC
J Invest Dermatol (United States) Jul 1982, 79
Suppl 1 p87s-89s
Increasing interest in the vascular features of
scleroderma has led to the hypothesis that the
blood vessel is the major target tissue and that
the endothelial cell is the principal cell target.
Useful observations stemming from the vascular
hypothesis include the use of microvascular
abnormalities in the early detection of the
patient destined to develop classical scleroderma,
the discovery of a serum protease selectively
cytotoxic to endothelial cells, and the study of a
serum mitogenic activity for fibroblasts in
scleroderma patients. Immune events related to the
vascular lesions are under active study but have
not as yet provided a unique immunological lesion
in scleroderma patients. The possibility that
immunity to basement membrane (type IV) collagen
may be selective for scleroderma patients deserves
further study. Persistent immunity to endothelial
basement membrane structures would provide a basis
for continued endothelial injury. Techniques to
quantify endothelial injury are useful to assess
activity of the vascular lesions and to monitor
therapies designed to block further vascular
injury. The definition of pre-fibrotic vascular
lesions may have future therapeutic and preventive
implications for scleroderma .

Progressive systemic sclerosis (PSS) is a
predominantly dermal disorder which may be
associated with epidermal atrophy. We investigated
epidermal function in 8 patients with PSS and
their healthy controls matched for age, sex and
racial group. We measured the vitamin D3
photosynthetic response to whole body irradiation
with ultraviolet light B (UVB). There were no
significant differences in basal serum vitamin D3
levels (mean +/- SEM: PSS 1.2 +/- 0.2 ng/ml;
controls 0.8 +/- 0.1 ng/ml; p greater than 0.1) or
post UVB blood values (PSS 5.2 +/- 1.4 ng/ml;
controls 6.9 +/- 1.1 ng/ml; p greater than 0.1);
although the increases post-UVB were significant
in both groups (p less than 0.01). In an
additional group of 19 patients with PSS and their
corresponding matched healthy controls, we
performed determination of random levels of the
active vitamin D metabolites, 25-hydroxyvitamin D
(25-OH-D) and 1,25-dihydroxyvitamin D
[1,25-(OH)2-D]. Similar levels were observed in
both groups: 25-OH-D PSS 28 +/- 3 ng/ml, controls
29 +/- 3 ng/ml; 1,25-(OH)2-D PSS 27 +/- 2 pg/ml,
controls 31 +/- 2 pg/ml (p greater than 0.1). None
of the correlations between skin area involved and
vitamin D3 formation or active circulating
metabolites reached statistical significance (p
greater than 0.1). We conclude that global
epidermal synthesis of vitamin D is retained in
PSS and, that the hepatic and renal vitamin D
hydroxylating mechanisms function normally in that
condition.

1,25-dihydroxycholecalciferol (1,25 (OH)2 D3)
causes dose-dependent inhibition of fibroblast
growth and collagen synthesis and has numerous
immunoregulatory activities. We assessed the
effects of oral 1,25 (OH)2 D3 in the treatment of
patients with systemic sclerosis (SS). Eleven
patients with SS entered an open prospective
study. Oral 1,25(OH)2 D3 was given at a mean dose
of 1.75 micrograms/day. The effects of the
treatment were evaluated using clinical
examination and physical measurements. After the
treatment period (6 months to 3 years), a
significant improvement, as compared with baseline
values, was observed. No serious side-effects were
observed. These results suggest that high-dose
1,25 (OH)2 D3 may be a useful therapeutic agent
for scleroderma .

1, 25 - Dihydroxyvitamin D3 [1,25(OH)2 D3] may
be an immunomodulatory drug which could have a
role in controlling collagen deposition, and
inducing reversal of fibrosis in some tissues.
These observations prompted a study of the
possible use of this hormone for the treatment of
scleroderma . A 35-year-old woman, who had been
suffering from localized scleroderma for 2 years,
was given oral 1,25(OH)2 D3 for 6 months. The
effects of the treatment were evaluated using
clinical and physical measurements (skin
thickness, extensibility properties of the skin).
The evolution of the patient's condition during
the 6-month therapy suggests that 1,25(OH)2 D3 is
beneficial in localized scleroderma . The
mechanisms of action are discussed in relation to
the literature, which suggests both
immunoregulatory and inhibitory effects on
fibroblast growth.
Isolation
and structural identification of 1, 25-
dihydroxyvitamin D3 produced by cultured alveolar
macrophages in sarcoidosis.

Hypercalcemia and hypercalciuria in sarcoidosis
are thought to result from the endogenous
overproduction of an active vitamin D metabolite.
We employed primary cultures of pulmonary alveolar
macrophages from two patients with biopsy-proven
pulmonary sarcoidosis and a recent or current
clinical abnormality in calcium metabolism to
synthesize in vitro a 1,25 - dihydroxyvitamin D3
[1,25-(OH)2D3]-like metabolite from
25-hydroxyvitamin D3 (25OHD3). The macrophage
metabolite cochromatographed with [3H]1,25-(OH)2D3
on normal phase and reverse phase high performance
liquid chromatography and was bound with high
affinity by the chick intestinal receptor for
1,25-(OH)2D3. On UV spectroscopy, the metabolite
possessed the carbon-5,7,10 (19) cis-triene
chromophore characteristic of a vitamin D sterol.
Electron impact mass spectrometry of
trimethylsilyl ether derivatives of the metabolite
revealed a mass fragmentation pattern similar to
that of the trimethylsilyl ether derivative of
authentic 1,25-(OH)2D3. The incubation of cultured
macrophages from two patients with idiopathic
pulmonary fibrosis and two with scleroderma with
[3H]25OHD3 did not result in production of a
metabolite with the chromatographic identity of
1,25-(OH)2D3. These data indicate that the
metabolite of 25OHD3 synthesized by sarcoid
macrophages in vitro is 1,25-(OH)2D3 and that the
macrophage is a synthetic source of the sterol
metabolite in sarcoidosis.

Over the years, many encouraging uncontrolled
studies extolling treatments of SSc have appeared,
but initial impressions were not corroborated when
controlled trials were done. This article points
out that certain recent studies have effectively
ruled out the use of some specific therapies for
the general treatment of systemic sclerosis. Thus,
sufficient data has been generated to rule out the
use of n-acetylcysteine, colchicine, chlorambucil,
cyclofenil, and DMSO, at least in disease of
longer duration. Ketanserin and prostaglandin
infusions probably also belong in this group, as
they affect only Raynaud's phenomenon. Angiotensin
enzyme inhibitors, while probably life-saving in
renal crises, do not seem to affect the underlying
systemic sclerosis per se. Another group of drugs
has only limited supportive data and await
well-controlled trials to prove or disprove their
effectiveness. These include: 5-fluorouracil,
D-penicillamine, drugs affecting platelet function
(dipyridamole), and para-aminobenzoic acid. There
are a few treatments which have potential. Factor
XIII has only limited data using controlled
trials, but what does exist seems positive.
Apheresis is encouraging, although the success of
this treatment modality may be dependent upon a
"combination" approach. Ongoing studies with
gamma-interferon, photopheresis, and the mast cell
stabilizer ketotifen appear exciting, and we await
reports of their use in scleroderma . On another
level, new insights into genomic alterations in
skin fibroblasts and T-cell proto-oncogene
expression have contributed to the understanding
of the pathogenesis of this disease at the
cellular level and new methods to measure change
in disease will help gauge response to therapy.
Thus, we look forward to more definitive treatment
of SSc in the future. (129 Refs.)

Using a blind method for assessing the results,
a study was made of the effect of
dimethylsulfoxide (DMSO) on fibrin formation and
microcirculation in 42 patients with rheumatic
diseases (rheumatoid arthritis, systemic
scleroderma, Raynaud's syndrome). It has been
shown that the therapeutic effect of DMSO in
rheumatic diseases is determined to a definite
degree by its normalizing action on fibrin
formation and microcirculation.

A prospective, randomized, double-blind trial
compared topical therapy with 0.85% normal saline,
2% dimethyl sulfoxide (DMSO), and 70% DMSO for
treatment of digital ulcers in 84 patients with
systemic sclerosis. There were no statistically
significant differences among the 3 treatment
groups in the improvement in the total number of
open ulcers, total surface area of open ulcers,
average surface area per open ulcer, number of
infected ulcers, number of inflamed ulcers, or
patient pain assessment. While some patients
improved during the study, improvement could not
be attributed to a specific treatment. Over
one-quarter of the patients treated with 70% DMSO
were withdrawn for significant skin toxicity.
The
effect of percutaneous dimethyl sulfoxide on
cutaneous manifestations of systemic
sclerosis.
Scherbel AL
Ann N Y Acad Sci (United States) 1983, 411
p120-30
DMSO exerts a palliative, therapeutic effect on
healing of cutaneous ulcers in systemic sclerosis.
The therapeutic response was variable and,
therefore, the concentration of DMSO, as well as
frequency and duration of treatments, should be
individualized to obtain maximum healing effect
with a minimum of adverse reactions. There was no
evidence of ocular toxicity or other serious
toxicity manifestations in this group of patients
treated with topical DMSO for one year or longer.
Delayed improvement was observed in the untreated
extremity in the majority of patients studied. In
no instance did improvement in the untreated
extremities exceed improvement in the treated,
bilateral counterpart. It is believed this
resulted from a systemic, carry-over effect of
DMSO rather than spontaneous improvement in the
disease course. DMSO is a worthwhile,
supplemental, therapeutic agent providing the
limitations of therapy are understood.
DMSO
revisited

Dimethylsulfoxide, more commonly referred to as
DMSO, was discovered in 1866. A clear, colorless,
odorless industrial solvent, it is hygroscopic in
nature and miscible with water and organic
solvents. In the mid 1960s, DMSO became popular
for its potential as a therapeutic agent and a
pharmaceutical solvent. Known as a wonder drug, it
was alleged useful in a variety of indications
ranging from arthritis to mental retardation. In
1965, the legal use of DMSO was restricted because
of ocular toxicity produced in animals during
various investigational studies. This side effect
was not confirmed in humans and DMSO is currently
approved in Canada for two indications:
scleroderma and interstitial cystitis. Various
experiments have looked at the external and
systemic adverse effects of topical application of
DMSO . Hemolysis, CNS toxicity, nephrotoxicity and
hepatotixicity have occurred after IV
administration of DMSO in humans. Similar
toxicities have appeared when DMSO was given
orally. The route of administration influenced the
nature and degree of toxicity observed. Ocular
toxicity was more prone to develop in animals when
DMSO was given orally. Teratogenic effects of DMSO
have been demonstrated in rabbits and chickens,
but not observed in other species.

This is a report of control trials using DMSO
in 199 patients. Seventy patients were diagnosed
as suffering from rheumatoid arthritis (RA), and
ranged in age from 17 to 75 years. Thirty-five
children ages 5-13 were diagnosed with juvenile
chronic arthritis (JCA). The diagnosis was made
according to American Rheumatology Association
(ARA) criteria. Sixty-five patients ranging in age
from 18-65, had Sjogren's syndrome. The diagnosis
was based on clinical and laboratory findings.
Twenty-nine patients suffered from systemic
scleroderma with pronounced and extensive skin
involvement. In 6 patients, ulcerations of fingers
were seen. All 199 patients continued basic
anti-inflammatory therapy: 60 received
corticosteroids (20-30 mg by mouth), 40 received
intra-articular hydrocortisone injections (due to
resistant synovitis) which were, however,
ineffective. The key selective principle was the
absence or a slight effect in response to the
basic therapy. Before DMSO application, all
patients had undergone a tolerance test: 50% DMSO
(always diluted with distilled water) was applied
on the back of the hand and 30% solution over the
parotid glands. The follow-up lasted for 24 hours.
Dermatitis on the tested areas was seen in only
two cases. These patients were excluded from the
trial. Patients and physicians knew that they were
receiving DMSO application but not the
concentration or drug combinations. These details
were known only to the chief of the experimental
trial, Dr. A.P. Alyabyeva. The course of treatment
lasted for two weeks. Each patient received 200 ml
of 50% DMSO .

The topical use of dimethyl sulfoxide (DMSO) as
a trigger substance for the accumulation of

compounds in regions of the extremities that have
acute or chronic venous disorders offers a new
approach to this still neglected therapeutic
field. The clinical results are in accordance with
the experimental findings and with the known
properties of DMSO itself.

There was a presentation of several slides
corresponding to 5 cases aged from 60 to 70 years,
similar to 9 cases collected by the Dermatological
School of Bordeaux and published in No 4 of 1972
of Annales de Dermatologie. It is the mixing of
other products (adrenoxyl, reptilase, vitamin B12)
with vitamin K1 that seems to produce a
pharmacodynamic incompatibility in subjects,
mostly cirrhotics, with a haemorrhagic syndrome.
The lumbo gluteal infiltrations appear in the
months following the injections. They spread out
in plaques of scleroderma, like a belt of armour,
right up to the trochanteric regions. They develop
for several years and no treatment is really
efficacious.
Glucose
intolerance in patients with chronic inflammatory
diseases is normalized by
glucocorticoids.
Hallgren R; Berne C
Acta Med Scand (Sweden) 1983, 213 (5) p351-5
Nine of 16 patients with inflammatory
connective tissue diseases (rheumatoid arthritis,
polymyalgia rheumatica, scleroderma and mixed
connective tissue disease) had glucose intolerance
defined a a K-rate less than one but a normal
early insulin response to intravenous glucose
loading. The degree of the impaired glucose
handling was related to the degree of inflammatory
activity as defined by acute phase reactants.
Glucocorticoid therapy induced within three days
an improved and normalized glucose tolerance and
an augmented early insulin response (p less than
0.001). The glucocorticoid effect was still
present up to six months of ongoing therapy. It is
suggested that glucose intolerance in chronic
inflammation is a consequence of a peripheral
insulin antagonism and an inhibition of insulin
secretion. This inhibition may be mediated
directly or indirectly by inflammatory cell
products and may be sensitive to
glucocorticoids.
Vitamin

We describe a 45-year-old white man in whom
distinctive clinical and histologic features of
localized scleroderma developed at sites of
injection of vitamin K1 (phytonadione). A direct
immunofluorescence test demonstrated prominent
linear deposition of IgA along the basement
membrane zone. No circulating antibasement
membrane zone IgA antibodies were identified on
indirect immunofluorescence testing. We believe
that the unusual immunofluorescence finding in our
patient is nonspecific and represents an
epiphenomenon caused by cutaneous injury. (18

Inhibition of collagen production by
traditional Chinese herbal medicine in scleroderma

Intern Med (Japan) Aug 1994, 33 (8) p466-71
The in vitro effect of one traditional Chinese
herbal medicine (Japanese name:
"Keishi-bukuryo-gan"), which has been empirically
used in scleroderma patients in China and Japan,
on collagen production in fibroblast cultures was
studied. Fibroblasts from 3 scleroderma patients
and 2 normal controls were incubated with various
concentrations of "Keishi-bukuryo-gan" and
collagen production was then determined by a
radiochemical method. "Keishi-bukuryo-gan"
significantly and selectively inhibited collagen
synthesis in a dose-dependent manner, with a
tendency of a stronger effect on scleroderma
fibroblasts than control cells. The results may
explain the clinical usefulness of this medicine,
and it may become a promising new agent for the
treatment of scleroderma.

The case of a 53-year-old man who developed
chloracne, palmoplantar keratoderma and
scleroderma after many years of exposure to a
variety of chloracnegens is reported. Chloracne is
a rare but important acneiform eruption associated
with exposure to halogenated aromatic compounds
used primarily in agriculture. However, to our
knowledge, the association of palmoplantar
keratoderma and scleroderma with exposure to
chloracnegens has not been previously
reported.
[Studies on stimulating circulation

(1) p19-21, 5
Of 725 cases of scleroderma, 265 were of
systemic type (the sex ratio being 1M:6F) and 460
of circumscribed type (the sex ratio being 1M:9F).
The patients were divided into three groups and
treated with three different stimulating
circulation to end stasis (SCES) prescriptions.
Satisfactory therapeutic effects were obtained in
all. According to the clinical practice and
laboratory findings, although SCES therapy exerted
manifold actions on the disease, it not only
softened the indurated connective tissues,
tonified the body and improved the symptoms, but
also improved laboratory indexes as follows:
nailfold bed capillary, parameter of the
peripheral blood stream in patients, content of
urinary 2-ketol, 17-KS, free corten, serum
joint-hexose, amino-hexose and histopathology
including ultrastructure of the skin. The main
effect was the improvement of circulation,
especially the microcirculation and regulation of
the metabolism of the connective tissues. Great
attention should be paid to the drug's function of
softening the indurated connected tissues. For
further investigation, the authors have stressed
three important points: screening of clinical
symptoms and signs, examination of blood
circulatory disturbances, and examination of
pathological changes of the connective tissue. The
necessity of developing new criteria for judging
the therapeutic effects was emphasized.

p70-6
T lymphocyte subpopulations were studied in 40
patients with scleroderma (PSS), 26 of whom were
studied simultaneously for lymphoproliferative
responses to phytohaemagglutinin (PHA),
concanavalin A (Con A) and pokeweed mitogen (PWM).
PSS patients exhibited a reduction relative to 42
age- and sex-matched controls in the absolute
number and percentage of early E rosettes, late E
rosettes and E rosettes formed with
aminoethylisothiouronium bromide (AET) treated
sheep red blood cells. There was no difference
between patients and controls in the proportions
of B lymphocytes. PSS patients exhibited normal
lymphocyte transformation responses to PHA and
ConA and an augmented response to PWM. The mitogen
responses did not correlate with the absolute
number or percentage of lymphocytes or T and B
lymphocyte subpopulations. No correlation was
observed between any immunological variable
studied and the extent of skin or organ
involvement, disease duration or therapy.
Lymphocyte reactivity to mitogens in
subjects with systemic lupus erythematosus,
rheumatoid arthritis and scleroderma.
Horwitz DA; Garrett MA
Clin Exp Immunol (England) Jan 1977, 27 (1)
p92-9
The mitogenic reactivity of lymphocytes from
subjects with systemic lupus erythematosus,
rheumatoid arthritis and scleroderma was studied.
Cultures containing either unseparated or
separated lymphocytes were stimulated with
phytohaemagglutinin, Con A and pokeweed mitogen
after inhibitory serum factors were eluted from
the cell surface. Incorporation of [3H]thymidine
in patient cultures was compared to that of normal
controls. Greatly decreased reactivity was found
in SLE to all three mitogens. Significantly
decreased values to some mitogens was also
observed in rheumatoid arthritis and scleroderma,
but the defect was less severe. Cultures of study
subjects contained significantly fewer small
lymphocytes than normal controls and this finding
explained at least in part the decreased mitogenic
reactivity.

Gastric emptying studies, using an indigenously
prepared radiolabeled solid food marker in the
form of Indian bread called Chapati, were
performed on 13 patients with systemic sclerosis.
Six patients had limited cutaneous disease and
seven had diffuse cutaneous disease. Earlier, the
procedure was standardized in 30 healthy
volunteers. Seven of the 13 (54%) patients (five
with diffuse and two with limited cutaneous
disease) had delayed gastric emptying. Most of
these patients had gastric symptoms. This pattern
of gastric emptying may be clinically significant,
particularly in patients with diffuse cutaneous
disease.

Forty cases of overlap syndrome of progressive
systemic sclerosis and polymyositis (OS PSS-PM)
are reported in this paper. All of these cases had
manifestations of both PSS and PM as well as
Raynaud's phenomenon. The sclerodermatous skin
changes were diffused over the whole body in most
cases. All cases had muscular weakness, elevated
skeletal muscle enzyme levels and muscle damage as
seen on the electromyogram. Histopathologic
changes showed characteristics of myositis. There
was noticeable systemic involvement, especially
with the digestive and circulatory systems.
Serologic examination frequently revealed
autoantibodies. The patients responded well to
traditional Chinese medicines and
corticosteroids.

We report a case of secondary antiphospholipid
syndrome (APS) occurring in a progressive systemic
sclerosis (PSS) patient who took herbal
medication. Clinical findings compatible with APS
included positive IgM anticardiolipin antibody
(ACL), thrombocytopenia, and obstruction of the
left radial artery on digital subtraction
angiography (DSA). Clinical findings compatible
with PSS included sclerodactyly and digital
ulcers, Raynaud's phenomenon, pulmonary fibrosis
and pulmonary hypertension, proteinuria and renal
mesangial reaction, and myocarditis.

Review of the pathophysiological, clinical and
pharmacological aspects of the
syndrome

Scleroderma is an uncommon but complex disease.
The onset is slow and the progress chronic. The
main pathophysiological changes vary, affecting
blood vessels, connective tissue, collagen fibres,
fibrin deposition and inflammatory reactions.
There may be early oedema and a wide spectrum of
organic involvement. Clinically, all the
fibril-containing and connective tissue organs are
subject to various degrees of attack. The most
common organic manifestations are: the Raynaud
phenomenon in the arms and hands, vascular
fibrosis, stiff and hard facial skin, restriction
of joint movement by pericapsular hardening,
calcium deposition and capsular rigidity. In the
gastro-intestinal tract, muscular atrophy,
collagen and connective tissue damage are common,
especially at the cardia of the stomach.
Malabsorption may occur. Progressive pulmonary
fibrosis leads to formation of cor pulmonale and
respiratory insufficiency. The liver, kidneys and
endocrine glands are seldom involved, however.
Therapeutic trials have been performed using many
different groups of drugs: experiment to influence
connective tissue, thyroxine, and a variety of
anti-rheumatic agents. In the last decade the best
short-term clinical results have been achieved
with penicillamine, some vasodilators,
chlorambucil (Leukeran), and, recently a potent
anti-oestrogen: cyclofenil, which has marked
connective tissue and collagen metabolism
influencing properties. Good therapeutic effects
without serious sideeffects have been
achieved.

A randomised, double-blind, placebo-controlled
trial with lithium succinate ointment was
conducted in patients with AIDS-associated facial
seborrhoeic dermatitis. Twice daily applications
of the ointment brought about a rapid (2.5 days)
and highly significant (P = 0.007) improvement in
the severity of the condition. Lithium succinate
ointment is well tolerated and can be a useful
treatment for seborrhoeic dermatitis in this group
of patients.

(2 Pt 1) p211-5
BACKGROUND: Morphea and linear scleroderma are
characterized by erythema, induration,
telangiectasia, and dyspigmentation. There is no
universally effective treatment. Oral calcitriol
has been beneficial in the treatment of localized
and extensive morphea/scleroderma, but the use of
topical calcipotriene has not been reported.
OBJECTIVE: The purpose of this study was to
evaluate the efficacy and safety of topical
calcipotriene 0.005% ointment in the treatment of
localized scleroderma.
METHODS: In a 3-month open-label study, 12
patients aged 12 to 38 years with
biopsy-documented active morphea or linear
scleroderma applied calcipotriene ointment under
occlusion twice daily to plaques for 3 months. The
condition of each patient had previously failed to
respond to potent topical corticosteroids and, for
some patients, systemic medications. Efficacy was
assessed at baseline, 1 month, and 3 months.
Levels of serum ionized calcium, intact
parathyroid hormone, and 1,25-dihydroxyvitamin D
and of random urinary calcium excretion were
measured.
RESULTS: During the 3-month trial, the
condition of all 12 patients showed statistically
significant improvement in all studied features.
No adverse effects were reported or detected
through laboratory monitoring of mineral
metabolism.
CONCLUSION: Topical calcipotriene 0.005%
ointment may be an effective treatment for
localized scleroderma, but double-blind placebo
controlled studies are needed for
confirmation.
Management of severe scleroderma with
long-term extracorporeal
photopheresis.

BACKGROUND: The management of systemic
sclerosis remains unsatisfactory. Thus far, the
action of extracorporeal photopheresis (ECP) in
severe systemic scleroderma has been evaluated in
short-term studies, and only limited experience
has been obtained with long-term application.
OBJECTIVE: The aim of the present study was to
evaluate prospectively the long-term effect of ECP
in a group of 16 patients suffering from severe
scleroderma, showing visceral involvement and
progressive clinical course.
METHODS: Fourteen patients with systemic
scleroderma involving several organs, 1 with CREST
syndrome and another with scleroderma-myositis
overlap syndrome were treated with ECP over a
period of 6-45 months. In 3 cases, gamma-IFN was
additionally administered. Skin and visceral
involvement were assessed by evaluating a series
of clinical criteria and results from laboratory,
imaging and functional tests.
RESULTS: Overall, clear improvement was
encountered in 6 patients, mixed response in 2,
stable disease in 3 and continuing progressive
course in 5 patients. Four out of 6 patients with
improvement were treated with ECP early after
onset of scleroderma (< or = 2 years), whereas
all patients with a progressive course under ECP
had had scleroderma for longer than 2 years.
Immunosuppressive drugs previously administered
could be reduced or fully withdrawn under ECP
treatment in 5 patients, but additional oral
medication was introduced in 4 patients due to
disease progression. Addition of gamma-IFN to ECP
did not reveal further benefit . No side-effects
were recorded under ECP treatment.
CONCLUSIONS: Based on this observation, we
believe that long-term ECP represents an effective
treatment modality in severe scleroderma
particularly when started early, with
stabilization of the disease course and partial
remission of the cutaneous findings, whereas
visceral involvement, if present, may rarely
improve.

PUVA therapy was carried out on four patients
with scleroderma; three of them had cutaneous
manifestations of progressive systemic sclerosis
and one other exhibited generalized morphea. PUVA
therapy was given with daily doses of 0.25J/cm2 or
0.4J/cm2 for 3-8 weeks, resulting in total doses
between 3.5J/cm2 and 9.6J/cm2. All four patients
responded well to this treatment; improvements of
hand closure, skin sclerosis index, and flexion of
fingers or knee joints were obtained. Thus, PUVA
appeared to be beneficial for treating
scleroderma.

p226-33
BACKGROUND: Scleroderma is a fibrotic disorder
of unknown etiology that is characterized by
excessive collagen synthesis and its deposition in
the skin and various internal organs.
OBJECTIVE: To examine whether an overproduction
of extracellular matrix molecules is a result of
either increased fibroblast proliferation or
increased collagen synthesis. As results of
clinical trials with 1,25-dihydroxyvitamin D3
(calcitriol) have suggested beneficial effect in
the treatment of scleroderma patients, the effects
of calcitriol on fibroblasts derived from
scleroderma and normal skin has been examined as
well.
METHODS: Cultures of fibroblasts were
established from biopsies from involved and
uninvolved skin of scleroderma patients and from
skin of healthy subjects, and compared with
respect to proliferation, collagen synthesis and
collagen lattice contraction.
RESULTS: No significant differences in cell
proliferation and in the extent of
fibroblast-induced collagen lattice contraction
have been found between scleroderma patients
exhibited a disorganized growth pattern in a
monolayer culture in contrast to normal
fibroblasts. Collagen synthesis tends to be higher
in scleroderma fibroblasts as compared with
controls. Calcitriol exerted an antiproliferative
and antisynthetic effect on fibroblasts, which,
however, did not discriminate healthy fibroblasts
from fibroblasts derived from involved or
uninvolved scleroderma plaques.
CONCLUSIONS: Our findings suggest that collagen
accumulation may not result from increased
proliferation or altered dynamic properties of
fibroblasts in a scleroderma lesion but from
increased collagen biosynthesis. We additionally
found that calcitriol does not selectively affect
scleroderma fibroblasts.
Effects
of tumor necrosis factor-alpha on connective
tissue metabolism in normal and scleroderma
fibroblast cultures.

Recent studies have demonstrated that tumor
necrosis factor-alpha (TNF-alpha) selectively
decreases production of collagens I and III, the
major types of collagen in the dermis, and
increases production of collagenase in cultured
dermal fibroblasts. The effects of TNF-alpha on
collagens I, III and VI, fibronectin and
collagenase gene expression by fibroblasts derived
from normal individuals and patients with systemic
sclerosis (SSc) were studied. SSc is characterized
by excessive accumulation of collagen in the skin
and in certain organs. TNF-alpha inhibited
collagen production and mRNA levels of collagens I
and III and of fibronectin, and stimulated
collagenase activity and collagenase mRNA levels
in SSs fibroblasts. Levels of mRNA for alpha 1
(VI) and alpha 3 (VI) collagen and for beta-actin
were unaltered in SSc fibroblasts incubated with
TNF-alpha. Similar results were observed for mRNA
levels in normal fibroblasts incubated with
TNF-alpha. These results suggest that TNF-alpha
could be expected to be beneficial in the
treatment of SSc. In addition, our results
indicated that collagen-VI expression is regulated
independently from expression of collagens I and
III, and expression of fibronectin and collagens I
and III are regulated in parallel in fibroblasts
treated with TNF-alpha.
[Treatment of severe Raynaud syndrome
in scleroderma or thromboangiitis obliterans with
prostacyclin (prostaglandin I2)]

Eleven patients with severe Raynaud's syndrome
were treated with intravenous infusion of
prostacyclin (Prostaglandin I2). Raynaud's
syndrome was caused by inflammatory diseases such
as progressive systemic sclerosis (N = 9) or
thromboangiitis obliterans (N = 2). Five patients
had acral ulcerations. Treatment with prostacyclin
lead to immediate cessation of acral pain in all
patients if doses of 5-6 ng/kg/min were tolerated.
In 7 out of 11 patients there was a long-term
analgesic effect with clinical improvement of
Raynaud's syndrome. In three of five patients we
achieved healing of the ulcerations within a few
weeks. Plasmaconcentrations of prostaglandin
F1-alpha, the main metabolite of prostacyclin,
were about 10 times above normal during infusion
and returned to normal levels within 30 min after
the end of the infusion, in spite of the prolonged
clinical effect. Therefore, prostacyclin alone
cannot be responsible for the long-term clinical
benefit . (Parts of this publication were
published as an abstract and presented at the 23rd
Congress of the Deutsche Gesellschaft fur
Rheumatologie (15).

To determine the efficacy of the mast
cell-stabilizing drug ketotifen in scleroderma, we
conducted a 6-month, randomized, prospective,
double-blind, placebo-controlled trial in 24
patients. No significant improvement in the
clinical parameters, pulmonary function, global
assessments, and mast cell releasability was
noted. Pruritus tended to improve in the group
taking the active drug. Six months of treatment
with ketotifen (6 mg/day), therefore, produced no
apparent benefit in patients with early
scleroderma. We were unable to address the role of
mast cells in scleroderma since mast cell
suppression was not achieved.

The administration of Factor XIII (FXIII)
produces a beneficial effect on the skin lesions
in about 50% of the treated patients with
progressive systemic sclerosis (PSS). The effect
of FXIII on various skin fibroblast functions
(proliferation, attachment, biosynthetic activity
and mechanical properties) was investigated in
vitro using normal and PSS strains. In cell
culture, most of the PSS fibroblast strains
synthesized excessive amounts of collagen. Other
cell functions such as adhesion to collagen I or
III, to fibronectin, retraction of collagen
lattices, proliferation in low serum concentration
and degradation of newly synthesized collagen were
not significantly different. The addition of FXIII
(I U/ml) inhibited the synthesis of collagen by
normal fibroblasts and reduced it in PSS
fibroblasts to a level similar to that of normal
fibroblasts. This effect was observed for cells
cultured on plastic or in a collagen lattice. In
the latter, an increased amount of collagen
degradation was observed. No significant effect of
FXIII on the other cell functions was noted.
Excessive collagen production by PSS fibroblasts
can be repressed by FXIII in vitro by at least two
distinct mechanisms: a reduction of collagen
synthesis and an increased degradation of the
newly synthesized collagen.

A six month controlled study of 5-fluorouracil
in the treatment of scleroderma showed a modest
benefit in skin scores, Raynaud's phenomenon, and
patients' global assessment. Visceral organ and
hand function were unaffected. Mild to moderate
toxicity was common in the 5-fluorouracil treated
patients but usually responded to dose reduction.
Two patients receiving 5-fluorouracil died from
causes seemingly unrelated to treatment.
Significant clinical improvement in scleroderma
was not noted in the first six months of treatment
with 5-fluorouracil.
Systemic scleroderma. Clinical and
pathophysiologic aspects.

Systemic scleroderma is a generalized disease
of connective tissue involving mainly the skin,
the gastrointestinal tract, the lungs, the heart,
and the kidneys. It can be present in different
forms, of which acroscleroderma, with limited
cutaneous and extracutaneous involvement, and
diffuse scleroderma within a more rapid
progression are most characteristic. Circulating
antibodies against antinucleolar antigens are
present in most patients with systemic
scleroderma. They are helpful for establishing a
classification and for determining the prognosis
of the disease; their involvement in the
pathogenesis, however, is still unclear.
Alterations of the blood vessels and induction of
fibroblasts by potent mediators are thought to
play an important role in the early phase of
scleroderma. Therefore early diagnosis is
required, which then can initiate vasoactive
therapy. In patients with systemic scleroderma,
who also suffer from additional myositis,
interstitial lung diseases, or arthritis,
anti-inflammatory treatment with prednisolone and
azathioprine is suggested. Development and
progression of fibrosis cannot yet be influenced
sufficiently. Only D-penicillamine affecting
cross-linking of collagen has been widely used in
scleroderma and has some beneficial effect. (160
