By a News Reporter-Staff News Editor at Gastroenterology Week -- A new study on Liver Diseases is now available. According to news reporting originating in Brussels, Belgium, by NewsRx journalists, research stated, "Background 82 Aims: Vitamin D deficiency has been frequently reported in advanced liver disease. However, its influence on alcoholic liver disease (ALD) has been poorly elucidated."

The news reporters obtained a quote from the research from the Free University of Brussels, "We investigated the association of vitamin D with clinical, biological, and histological parameters and survival in ALD patients. Furthermore, we explored the effect of vitamin D treatment on ALD patient peripheral blood mononuclear cells (PBMCs), and in a murine experimental model of ALD. Serum levels of 25-hydroxyvitamin D [25(OH)D] were determined in 324 Caucasian ALD patients and 201 healthy controls. In vitro experiments on vitamin D pre-treated PBMCs evaluated TNF alpha production by ELISA in culture supernatants. Mice were submitted to an ethanol-fed diet and some of them were orally supplemented three times per week with 1,25(OH)(2)D. Severe deficiency in 25(OH)D (<10 ng/ml) was significantly associated with higher aspartate aminotransferase levels (p = 1.00 x 10(-3)), increased hepatic venous pressure gradient (p = 5.80 x 10(-6)), MELD (p = 2.50 x 10(-4)), and Child-Pugh scores (p = 8.50 x 10(-7)). Furthermore, in multivariable analysis, a low 25(OH)D concentration was associated with cirrhosis (OR = 2.13, 95% CI = 1.18-3.84, p = 0.013) and mortality (HR = 4.33, 95% CI = 1.47-12.78, p = 7.94 x 10(-3)) at one year. In addition, in vitro, 1,25(OH)(2)D pretreatment decreased TNF alpha production by stimulated PBMCs of ALD patients (p = 3.00 x 10(-3)), while in vivo, it decreased hepatic TNF alpha expression in ethanol-fed mice (p = 0.04). Low 25(OH)D levels are associated with increased liver damage and mortality in ALD."

According to the news reporters, the research concluded: "Our results suggest that vitamin D might be both a biomarker of severity and a potential therapeutic target in ALD."
