BACKGROUND: Liver disease due to hepatitis C virus (HCV) is an increas
ingly frequent indication for liver transplantation. We performed a cl
inical and virological study of 20 HCV-infected liver transplant recip
ients to correlate virological markers with histological recurrence of
disease. PATIENTS AND METHODS: In ninety-four patients who were given
transplants for end-stage cirrhosis, IgG and IgM antibodies to HCV an
d IgM to HCV tested by ELISA; all samples were further examined in a f
our-antigen recombinant immunoblot assay (2-RIBA). HCV viremia was mea
sured by the conventional nested PCR. HCV genotype was determined by P
CR amplification using type-specific primers. We have analized de nova
infection by HCV, HCV recurrence and the influence of genotype in the
se recurrence. RESULTS: Nineteen of 20 antibody-positive patients (95%
) had HCV RNA before transplantation. All 19 patients who were viremic
before transplantation had persistent infection after LT. HCV genotip
e Ib was the predominant type before and after LT (75%). Ten of the 20
(50%) patients developed histological findings of chronic hepatitis (
CH) in liver allografts. HCV recurrent liver disease after LT was not
related with HCV genotype. Of 4 deaths after transplant in hepatitis C
group, only one was related to recurrent disease. We have not found d
e nova hepatitis C. CONCLUSIONS: Our results indicate the general pers
istence of hepatitis C virus infection and the excellent short-term pr
ognosis after liver transplantation. Chronic hepatitis by HCV in liver
transplant was not related with HCV genotype.
