Background/Aims: Preferential production of immunoregulatory cytokines may play an important role in the pathogenesis of chronic hepatitis B. Patients with chronic hepatitis B infection were evaluated to determine whether serum interleukin-10 (IL-10) levels were changed and whether the degree of these changes in serum levels correlated with HBV DNA levels, histologic activity index (HAI) or serum aminotransferase levels (ALT). Methodology: 15 patients diagnosed of chronic hepatitis B (wild type) with raised ALT, 15 inactive HBsAg carriers, 15 healthy people with resolved acute hepatitis B, and 15 healthy controls without any hepatitis marker positivity were included in the study. Serum IL-10 levels were measured. The associations between liver pathology, HBV DNA and ALT levels were assessed. Result: IL-10 is elevated more in chronic hepatitis B with positive HBeAg and raised ALT in comparison to asymptomatic carrier, resolved acute hepatitis B and control. Conclusions: IL-10 production is increased in chronic hepatitis B patients with HBeAg positivity and raised ALT as compared to other groups ( p < 0.01). No correlation between HBV DNA, HAI or ALT could be established through this study. However, as IL-10 is increased in chronic hepatitis B infection with HBeAg positivity, the HBe antigen may be responsible for the raised IL-10 levels.
