title: [Viral hepatitis A: causes of lingering].
abstract: The examination covered 756 patients with viral hepatitis A (90 of them were followed up for 1.5 years) who had antigens and antibodies to hepatitis A, B, C, E and D viruses. It was found that: lingering viral hepatitis A may be caused by viral persistence marked by specific antibodies (IgM anti-HAV); lingering hepatitis followed by verification of chronic hepatitis is related to manifestation of previous hepatitis B and C; detection of IgM anti-HAV in patients with exacerbation of chronic hepatitis B, C and D (hepatitis D) evidences for the presence of mix-infection (acute hepatitis A in chronic hepatitis B, C or D).
