Drug-related hepatotoxicity in a renal transplant recipient with long-term survival and hepatitis C

Drug-related hepatotoxicity is more common in renal transplant (RT) recipients with chronic liver disease because drug metabolism is not as efficient in these individuals. We describe a long-term survivor (30 years) of renal transplantation with hepatitis C virus (HCV) and drug-related hepatotoxicity. Our patient, a 26-year-old male, developed uremic syndrome in May 1976 and received a renal allograft from a related, living donor with an identical human leukocyte antigen genotype in August 1976. Maintenance immunosuppression treatment consisted of azathioprine (AZA) and prednisone. In 1993, the patient tested negative for HCV antibody v1.0 (anti-HCV). In 2000, the patient had elevated aminotransferases, which was attributed to pravastatin treatment. Remission of this abnormality was achieved once pravastatin was discontinued. In 2003, the patient again exhibited elevated levels of aminotransferases and AZA-related hepatotoxicity was suspected; therefore, AZA was discontinued and treatment with mycophenolate mofetil was initiated, which led to normal aminotransferase levels. The patient tested positive for anti-HCV v3.0 and HCV RNA and a liver biopsy showed chronic hepatitis with moderate activity. Currently, the patient’s renal transplant and liver are functional. In conclusion, hepatotoxic drugs should be used with caution in renal transplant recipients and close monitoring of liver function in patients with chronic viral hepatitis is crucial.
