[Hepatitis A: antibody conversion under gamma globulin (author's transl)].

55 soldiers of the Austrian UNO contingent to the Near East, stationed on the Golan Heights for 6 months were examined before and after their period of duty for hepatitis A antibodies and the liver specific enzymes GOT, GTP and gamma-GT were determined. All received prophylactic gamma globulin to prevent infectious hepatitis at a dosage of 0.05 ml/kg body weight before flying out and after three months. No cases of hepatitis occurred, but 4 sero-negative subjects displayed antibody conversion. No concomitant changes in the liver enzyme values were recorded, however. These findings are discussed.
