Abstract

© Copyright 2017, Mary Ann Liebert, Inc. 2017.Toll-like receptors (TLRs) may play an important role in hepatitis-B pathogenesis. However, serum TLR-2 and TLR-4 levels and their association with serum liver enzymes, hepatitis B virus (HBV) DNA, quantitative HBsAg levels, and liver biopsy findings, are unknown. A total of naive 40 HBeAg (-) chronic hepatitis B (CHB) patients and 20 healthy control subjects were recruited in this study. Liver tests, HBV DNA, serum TLR-2 and TLR-4, and quantitative HBsAg levels were evaluated among all groups. The relationship among TLR-2, TLR-4, quantitative HBsAg levels and liver tests, and liver histological findings were investigated with correlation analysis. Serum TLR-2 and TLR-4 levels in HBeAg (-) CHB patients were higher than in the control group. There was a positive correlation between serum TLR-2, TLR-4, and HBV DNA and ALT levels. We have further demonstrated that serum TLR-2 levels are correlated with AST and quantitative HBsAg levels. However, TLRs levels were not linked to the liver biopsy findings. TLR can have an important role in hepatitis B pathogenesis. Liver injury in CHB may cause elevated TLR-2 and TLR-4 levels.
