    Abstract:
    Serum HBs antigen (HBs Ag) and anti-HBs antibody (anti-HBs), as determined by radioimmuno-assay or ELISA methods, were studied in a group of 77 patients with acute icterogenic viral hepatitis over a period of at least three months and correlated to the evolution of the disease either to return to good health or to a chronic state. The cumulative rate of patients in whom HBs Ag had disappeared (n = 53) was a linear function of time during the first sixteen weeks. Correlation seemed even stronger in the subgroup of patients restored to good health before the third month. Time of HBs Ag disappearance ranged from 5 days to 5 months in common forms of hepatitis. There was no evident correlation between the time of disappearance and the normalization of ALAT levels. Among the four cases of chronic persistent hepatitis, three had no detectable antigenemia six months later. Development of anti-HBs preceded the loss of HBs Ag in one case, was simultaneous or posterior to it in all other cases; the absence of any serologic HBV marker could last up to 4 months. No chronological link was found between seroconversion and normalization of ALAT levels. The correlation between time and HBs Ag disappearance from the blood could be specific for a given group of patients placed under specific conditions; its determination might help in understanding the factors that influence the course of the disease.
