Effect of Serum Vitamin D Level on the Efficacy of Peg-interferon Treatment in CHB

Chronic Hepatitis b Clinical Trial

Official title:
Effect of Serum Vitamin D Level and Vitamin D Receptor on the Efficacy of Pegylated Interferon in Patients With Chronic Hepatitis B With Low Level HBsAg Treated by Nucleos(t)Ide Analogues

Clinical Trial Summary

In recent years, vitamin D (VD) has received much attention in the fields of host immune regulation, inflammation, fibrosis, cell proliferation and differentiation and tumor. VD works by binding to the vitamin D receptor (VDR). VDR is mainly distributed in giant cells, dendritic cells, T cells and lymphocytes. Four SNPs of VDRS have been most studied: TaqI (rs731236), FokI (rs10735810), ApaI (rs7975232), and BsmI (rs1544410). At present, more and more patients have been treated with oral nucleotide/nucleoside analogues (NAs) with direct antiviral drugs in China, and a large part of them show low expression of HBsAg. Clinical cure can be pursued for these patients, that is, HBsAg turns negative. A number of studies have been carried out at home and abroad. In this study, We will recruit CHB patients with low HBsAg levels. They all will receive pegylated interferon treatment and were randomly assigned to a vitamin D treatment or a control group. A final assessment will be made to determine whether vitamin D levels would affect the clearance rate of HBsAg.
