Abstract: Treatment of serum precipitates with sodium thiocyanate in patients with hepatitis B virus (HBV) replication results in liberation of circulating hepatitis core antigen (HBcAg) which can be demonstrated radioimmunologically. Follow-up investigations were performed in 80 patients with acute hepatitis B. Sera were examined for HBcAg. HBV DNA and conventional HBV markers. At the time of admission to hospital 34 of 80 (42%) patients were HBeAg positive. Twenty-six (76%) of the 34 HBcAg positive patients were HBV DNA positive, and circulating HBcAg was detectable in 25 of 34 (73%) HBcAg positive cases. In patients with uncomplicated courses of acute hepatitis B the serological HBcAg assay and HBV DNA became negative 1 to 8 weeks before elimination of HBeAg and up to 12 weeks earlier than the sera became negative for HBsAg. Five patients (6%) showed transition to chronic hepatitis B with persistence of HBsAg, HBeAg, HBV DNA and HBcAg in serum. One patient with acute hepatitis B and development of chronic hepatitis suffered from acquired immunodeficiency syndrome and showed delayed formation of anti-HBc. In this case uncomplexed HBcAg was demonstrable during the acute phase of hepatitis B. With the appearance of anti-HBc HBcAg circulated in a complexed form. The data indicate that serological determinations of HBcAg and HBV DNA can serve as prognostic markers in the early phase of acute hepatitis B. The demonstration of uncomplexed HBcAg in serum of a patient with inadequate formation of anti-HBc supports the hypothesis that circulating HBcAg is usually complexed by specific antibodies.
