Some sex- and age-dependent correlations in acute viral hepatitis.

: HBsAg was found to be present in 28.7% of 1980 sera from acute viral hepatitis (AVH) patients tested by immunodiffusion and counterimmunoelectrophoresis. The incidence of HBsAg-positive AVH cases was lower in female subjects aged 10-19 years. The follow up of SGPT, bilirubinemia and thymol turbidity kinetics in 473 of the patients revealed some HBsAg-dependent differences. Such differences oscillated more markedly in adults than in children and were less obvious in women. The possible involvement of certain individual factors in the determinism of hepatitis B virus infection and of its further evolution is suggested.
