ABSTRACT
Nine hundred and sixteen schistosomal patient together with 97 non-schistosomal controls were examined for the presence of HBs-Ag and anti-HBs in their sera by counter-immunoelectrophoresis (CIEP). The results are reported and statistically analysed. HBs-Ag, anti-HBs and the exposure rate were found significantly higher in schistosomal patients than in controls. The frequency of HBs-Ag was not significantly different in the active and inactive schistosomal groups, while the anti-HBs was significantly higher in the inactive group. S. mansoni-infected cases showed significantly higher frequency of HBs-Ag and anti-HBs than cases with S. haematobium. The prevalence of HBs-Ag was highest between 20-39 years of age in the schistosomal group, while the anti-HBs was maximum at the age of 30-39 years. There were no sex differences in the prevalence of HBs-Ag and anti-HBs in both schistosomal and control groups. However, a significantly higher frequency of anti-HBs was found between male patients and male controls. The same was true for females. Patients with history of parenteral anti-bilharzial treatment and blood transfusions were accompanied with significantly higher percentage of HBs-Ag and anti-HBs. The importance and significance of the results are discussed.

The study included 916 schistosomal patients and 97 controls. The prevalence of HBs-Ag and anti-HBs was significantly higher in the bilharzial patients compared to controls. Their frequency was higher in the ascitic than the hepatosplenic group, and the difference between each and the simple group was highly significant. Cases with current jaundice showed highly significant frequency of both HBs-Ag and anti-HBs compared to those with no history or manifest jaundice at the time of study. In addition, cases with raised bilirubin, SGPT and SGOT showed significantly higher frequency of HBs-Ag and anti-HBs compared to cases having normal levels. On the other hand, the frequency was not affected by the level of serum alkaline phosphatases. As regards liver pathology, cases with mixed pathologic picture showed significantly higher frequency of both HBs-Ag an anti-HBs compared with those having pure schistosomal lesions.
