title: [Recurrence of hepatitis caused by hepatitis c virus in patients receiving a liver transplant].
abstract: BACKGROUND
  Liver disease due to hepatitis C virus (HCV) is an increasingly frequent indication for liver transplantation. We performed a clinical and virological study of 20 HCV-infected liver transplant recipients to correlate virological markers with histological recurrence of disease.
  
  
  METHODS
  In ninety-four patients who were given transplants for end-stage cirrhosis, IgG and IgM antibodies to HCV and IgM to HCV tested by ELISA; all samples were further examined in a four-antigen recombinant immunoblot assay (2-RIBA). HCV viremia was measured by the conventional nested PCR, HCV genotype was determined by PCR amplification using type-specific primers. We have analyzed de novo infection by HCV, HCV recurrence and the influence of genotype in these 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 genotype 1b 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 de novo hepatitis C.
  
  
  CONCLUSIONS
  Our results indicate the general persistence of hepatitis C virus infection and the excellent short-term prognosis after liver transplantation. Chronic hepatitis by HCV in liver transplant was not related with HCV genotype.
