Recurrent hepatitis B, hepatitis C, and combined hepatitis B and C in liver allografts: a comparative pathological study.
Although recurrence of viral hepatitis in liver transplants is common, data comparing recurrent hepatitis B (HB), hepatitis C (HC), and co-existing dual hepatitis B and C (HB&C) are sparse. Posttransplantation liver biopsies, along with molecular, serological, immunohistochemical, and clinical data from 27 patients with pretransplantation diagnosis of chronic viral hepatitis, were reviewed. The patients were placed into 4 groups: Group I, with pretransplantation HB (n = 8); group II, with pretransplantation HC (n = 10); group III with pretransplantation HC and anti-HB surface or core antibody (n = 4); and group IV, with pretransplantation HB&C (n = 5). The histopathologic findings and patient outcome were compared in the 4 groups. A high rate of recurrence of viral hepatitis was seen for all 4 groups: Group I = 100%, group II = 90%, Group III = 100%, and group IV = 80%, with the mean (median) recurrence time of 308 (224), 82 (52), 61 (64), and 125 (70) days, respectively. The number of deaths (their median survival times) were: group I = 4 (374 days), group II = 4 (794 days), group III = 1 (1,143 days), and group IV = 5 (448 days). The earliest histological findings of lobular injury was the presence of acidophil bodies and Kupffer cell hyperplasia, the latter being more prominent in recurrent HC cases. Recurrent HB presented in 2 forms: early (before 150 days) with poor survival and with either severe necroinflammatory histology or with features of fibrosing cholestatic hepatitis, and delayed (after 150 days), with mild necro-inflammatory activity and prolonged survival. HC with or without anti-HB antibodies had early recurrence, but the course was slowly progressive. Patients with HB&C had recurrence of both viruses; however, the course was dictated by HB virus.
