Chronic hepatitis: a follow-up study.

51 cases of chronic hepatitis were followed up by serial liver biopsies. 6 cases, all of which were of the active type, showed transition to liver cirrhosis within 5 to 10 months after the initial biopsy which had indicated chronic hepatitis. In 109 cases of liver cirrhosis, the antecedent acute hepatitis had been found within a relatively short period, usually 2 to 3 years before the establishment of the diagnosis of liver cirrhosis. Whether these cases which showed rapid transition to liver cirrhosis after acute hepatitis should be included in the group of chronic hepatitis or in another group remains to be settled.
