Abstract
Our purpose was to establish the earliest histologic parameters of acute hepatitis that correlated with recurrent hepatitis C virus (HCV) infection in liver allografts. Histologic reviews of posttransplant liver biopsies from eight patients with pretransplant chronic HCV (group I) and eight with pretransplant non-HCV liver disease (group II) were performed and correlated with concurrent or subsequent presence or absence of HCV-RNA by polymerase chain reaction (PCR). Six of eight group I patients developed HCV-RNA positivity in liver and serum. Of the histologic parameters studied, the presence of Kupffer cell hyperplasia, spotty hepatocellular necrosis (acidophil bodies), or both, correlated the most with the earliest diagnosis of acute recurrent hepatitis. The postoperative time period for the earliest diagnosis of recurrent HCV was variable (34 to 123 days). These early indicators and the time of their appearance were not predictive of the course of the disease process or the final outcome of the patient. The recurrence rate of HCV infection in liver allografts is high. The presence of Kupffer cell hyperplasia and diffusely scattered acidophil bodies are reliable, early histologic indicators of an acute hepatitic process.
