Sera of 1 55 chronic hepatitis (CH) patients in Argentina were tested for the presence of HBsAg, anti-HBs, anti-HBc, and anti-HAV. Our purpose was to define the role that both virus A and B might play in the etiology and pathogenesis of this condition. The patients were divided into two groups: group I (57) HBsAg-negative; group II (98) HBsAg-positive. The control group consisted of 1,209 healthy blood donors from Banco Central de Sangre de Rosario; 286/ 1,209 (24%) had viral markers for HBV. In group I, 38/57 (67%) had anti-HBs and/or anti-HBc, but none had anti-HBs alone. Group II showed a higher percentage of males (P < 0.05). We found similar incidence of anti-HAV among group I, group II, and the control group. |
