Influence of human immunodeficiency virus infection on chronic hepatitis B in homosexual men.

The aim of this study was to assess the influence of human immunodeficiency virus (HIV) infection on chronic hepatitis B. In a series of 132 (65 anti-HIV positive) homosexual non-drug addicted men with chronic hepatitis B, the liver function was assessed with biochemical tests; the degree of hepatitis B virus (HBV) replication was assessed with serum HBV DNA level and with immunoperoxidase staining of hepatitis B core (HBc) antigen on liver specimens; and the severity of liver lesions was assessed with an histology activity index. Anti-HIV-positive and anti-HIV-negative patients were not different for serum aspartate transaminase activity, bilirubin, prothrombin, and histology activity index. Anti-HIV-positive patients had lower serum alanine transaminase activity levels (P =.0001), lower serum albumin levels (P =.0009), and higher serum HBV DNA levels (P =.01). There was a higher prevalence of cirrhosis in anti-HIV-positive patients (P =.04). In homosexual men with chronic hepatitis B, HIV infection is associated with a higher level of HBV replication and a higher risk for cirrhosis without increased liver necrotico-inflammatory process.
