title: Behaviour of hepatitis B antigen in bilharzial patients infected with HBs positive viral hepatitis.
abstract: A TOTAL of 204 cases with acute viral hepatitis were studied: 93 bilharzial and 111 non-bilharzial. This study is concerned with the 106 cases showing positive HBS Ag test. Follow up of the cases after discharge from the Fever Hospital was carried out by repeated clinical and laboratory examinations 3 montly in the first year and 6 monthly subsequently. The bilharzial and non-bilharzial patients were found to be equally susceptible to HBS Ag positive hepatitis (p=0.25). However, antigenaemia tended to last longer as a whole in the bilharzial patients (p=0. 005) and was not affected by successful specific antibilharzial treatment. It seems that bilharzial infection predisposes to "retention" of HBs antigen, after subsidance of the acute attack, thus increasing the volume of reservoir for HB virus in our rural community.
