[The frequency of the e-antigen in acute and chronic hepatitis (author's transl)]

Five groups of patients were studied: (a) 88 HBsAg-positive cases of acute viral hepatitis (AVH) who completely cured within 90 days; (b) 75 cases of acute HBsAg-negative hepatitis with early resolution; (c) 15 AVH patients who became chronic; (d) 94 HBsAg-positive cases of chronic hepatitis (CH) and liver cirrhosis; (e) HBsAg-negative cases with CH. The e-antigen was investigated in every patient and was found in 9 of the AVH cases with favorable evolution, and in 8 of the AVH patients evolving to chronicity. Amont the CH and cirrhosis group, 48 of the HBsAg carriers were positive while e-antigen could not be detected in any of the HBsAg-negative ones. The high incidence of e-antigen carriers among patients with chronic hepatitis and liver cirrhosis as well as among those with AVH who later entered the chronic stage of the disease, deserves especial consideration. A possible role of e-antigen in the evolution to chronicity and a prognostic significance is suggested.
