[Immunoprevention of hepatitis B in children of HBsAg-positive pregnant patients]

Abstract

Children of hepatitis-B-surface-antigen-positive women are, depending upon the degree of maternal infectivity, exposed to a very different risk of hepatitis B. In the GDR the rate of infectious pregnant women is low. The serious consequences of a perinatal hepatitis B, which very often leads to a chronic course and virus carriers, may widely by prevented by immunoprophylaxis. Various methods for the establishment of a risk are described. The hepatitis-B-surface-antigen screening in 28 127 pregnant woman showed 20 = 0,07% of carriers of findings, 4 out of them HBeAg-positive. From the performance of the passive immunisation in 6 babies of HbeAg-positive mothers and 2 newborn without maternal HBe- or anti-HBe-proof and from the results of the control of 17 children, who were not immunized, when there was an anti-HBe-positiveness or when there was no proof of HBe-markers, result recommendations for practice.
