Correlation between e/anti e system and evolution of B virus chronic hepatitis in pediatric patients.

The authors have performed a longitudinal study of 118 children affected with B virus chronic hepatitis. Our first observation revealed 92 children with HBeAg positive (26 CPH, 66 CAH), 22 children with anti HBe positive (6CPH, 15 CAH, 1 cirrhosis), 4 children (CAH) with e/anti-e negative. A correlation between the severity of clinical forms and the behaviour of the e/anti-e system was not observed. Seroconversion was observed during the follow up period in 37 of 92 subjects in an average time of 59.83 +/- 32 months, time rather prolonged in patients under immunosuppressive therapy. To compare the clinical progress and the evolution of CPH and CAH respectively, always with regard to the e/anti-e system, statistically significant differences did not result. Only anti HBe positive recovered subjects, inclusive of seroconverted patients and those anti HBe from the first observation, showed significant results to the statistical analysis. Still, seroconversion corresponds frequently to a stable improvement of hepatitis. On the contrary evolution into cirrhosis was observed in 5 patients that had anti HBe antibodies.
