Abstract

The current standard of care therapy (SOC) for chronic HCV is pegylated interferon/ribavirin (Peg-IFN/RBV). Many reports showed the possible role of vitamin D supplementation in augmenting the response to SOC. The aim of this study was to assess the role of vitamin D supplementation on the response to treatment in chronic HCV genotype 4 patients. One hundred and one chronic HCV patients were classified into two groups (Group 1): 51 patients received the SOC therapy consisting of Peg-interferon alfa-2b plus ribavirin, (Group 2): 50 patients received the SOC therapy+vitamin D3 (Cholecalciferol) in a dose of 15,000‚ÄČIU/week during the treatment course. Vitamin D deficiency was found in 95% of patients. No correlation was found between vitamin D levels and stage of fibrosis in the whole population. Vitamin D supplementation had no positive impact on treatment outcome where sustained virological response (SVR) was achieved in 51.2% in group 2 and 71.4% in group 1 by per-protocol analysis and in 44% in group 2 and in 68.6% in group 1 by intention to treat analysis (P value 0.22 and 0.220 respectively). Despite its role in other genotypes, vitamin D supplementation has no significant impact on SVR in HCV Genotype 4 patient. No correlation was found between vitamin D levels and stage of liver fibrosis.
