Hepatitis C virus infection and kidney transplantation.

Hepatitis C virus (HCV) infection is an important problem in the patient with end-stage renal disease. After transplantation, liver disease is more frequent in HCV-positive patients than in HCV-negative patients. In the long run, this leads to important liver complications. The patients have a higher risk for developing proteinuria and infections. Long-term patient and graft survival rates are lower in HCV-positive patients than in HCV-negative graft recipients. Mortality is higher, mainly as a result of liver disease and infections. Despite this, transplantation is the best option for the HCV-positive patient with end-stage renal disease. Transplantation of HCV-positive kidneys should be offered to HCV-positive recipients in whom HCV RNA is detected in the serum. Finally, several measures after transplantation minimize the consequences of HCV infection. Adjustment of immunosuppression and careful follow-up in the outpatient clinic for early detection of proteinuria, infection, or worsening of liver disease are mandatory.
