[Diagnostic and prognostic criteria in acute non-A, non-B viral hepatitis with a prolonged course]

In a prospective three-year-long study of Non-A, Non-B infections carried out in the Institute of Infectious and Tropical Diseases in Belgrade, by a method of exclusion and in about 30% of patients' liver biopsies, 75 cases of acute viral hepatitis Non-A, Non-B were discovered. It makes only 2.29% of all cases of acute viral hepatitis diagnosed and treated in the same period in this institution. In prolonged forms of the disease (24 cases) the chronicity was shown by epidemiological data (posttransfusion hepatitis), fluctuation of transaminase and rise of gamma globulins in acute phase of the disease. Liver biopsies performed in the first four months of the disease were of no prognostic value.
