[Post-transfusion viral hepatitis B and C and criteria of their differentiation].

Two groups of adult patients suffering from posttransfusion viral hepatitis (PTVH) were examined. Group I included 179 patients with PTVH B, group 11 72 patients with PTVH C. Both types of the disease exhibited similar epidemiological, clinical and biochemical serum characteristics, seemed to arise against preexisting diseases. Type C occurred more frequently among females, had shorter latent period, ran a light course. To differentiate between PTVH types B and C, practitioners are recommended to regard duration of the latent period, incidence of acute period HBsAg, anti-HBs, anti-HBc, IgM in the serum, HBs-antigenemia occurrence in donors suspected of PTVH induction, history of serologically confirmed viral hepatitis B.
