title: Chronic liver disease rarely follows acute hepatitis B in non-immunocompromised adults.
abstract: The risk of developing a chronic carriage state after acute hepatitis B infection in adults was evaluated. Two hundred and eighty-nine HBV-susceptible heterosexual partners of acute hepatitis B patients were used to investigate the effectiveness of post-exposure immunoprophylaxis; 75 of them received hepatitis B vaccine, 72 hepatitis B hyperimmune globulin (HBIG), 71 vaccine plus HBIG and 71 placebo. Participants were interviewed, clinically examined and serum specimens were taken at 1, 3, 6 and 9 months after their first intervention. Serum samples were tested for ALT and HBV markers (HBsAg, anti-HBc and anti-HBs) using radio immunoassays. Forty-six (15.9%) of the heterosexual partners examined were infected; the incidence of HBV infections was higher among placebo (18.3%, 13/71) and HBIG (18.1%, 13/72) recipients compared to vaccine (16.0%, 12/75) and HBIG plus vaccine (11.3%, 8/71) recipients, but the differences were not statistically significant. Infections were significantly more often subclinical after immunoprophylaxis (p = 0.03). HBsAg was detected in all eight clinical and in 13 of the 38 subclinical cases. In the remaining 25 subclinical cases HBV infections were diagnosed by the development of anti-HBc and anti-HBs during the follow-up period. Finally, all 46 cases studied cleared the HBsAg.
