title: Hepatitis B virus variants in patients with acute hepatitis in whom various clinical forms develop.
abstract: Ten patients who suffered from acute hepatitis with various clinical forms due to hepatitis B virus (HBV) were studied. HBV variants with a mutation in the precore region were dominant in two patients with fulminant hepatitis and in a patient with the most severe acute hepatitis. However, these mutant viruses were not detected in a patient who had the fulminant form of acute HBV infection on chronic liver damage or in most patients who had severe acute hepatitis. Furthermore, mutant viruses were also not detected in a patient with complicating myopathy and in one who had an atypical clinical course with three transaminase peaks. These results suggest that precore mutants may be involved in the pathogenesis of some cases of severe acute hepatitis, the same as for fulminant hepatitis, but not in other clinical forms of acute hepatitis.
