title: Clinico-pathological study of acute non-A, non-B post-transfusion hepatitis: histological features of liver biopsies in acute phase.
abstract: A follow-up study of acute non-A, non-B post-transfusion hepatitis with a mean follow-up period of 30 months was carried out in 24 patients in whom liver biopsy was done within 3 months of onset. Of the 24, 13 patients (54%) developed chronic biochemical liver disease with elevated serum aminotransferases for more than 6 months, and in 11 the elevated liver enzymes were normalized within 6 months. Although there were no statistically significant differences in the mean peak values of liver enzymes, length of incubation period and number of transfusions between the chronic and resolved groups, the former tended to have a slow rise and multiple peaks of serum liver enzymes. Analysis of the liver biopsies made in the acute phase revealed that limiting plate erosion, hepatocellular degeneration, and poor regenerative activities were indicative of subsequent transition to chronicity. Multiple biopsies were taken in five patients who were followed for an average of 29 months, and the subsequent histological diagnosis was chronic persistent hepatitis in two, chronic active hepatitis in two and cirrhosis in one.
