title: Treatment of recurrent hepatitis C post-liver transplantation.
abstract: Recurrent hepatitis C after liver transplantation is universal. Graft reinfection occurs rapidly, with chronic hepatitis and rapid evolution from end-stage liver disease. Within 5 years until 30% of patients with recurrent disease ultimately progress to cirrhosis, and survival of transplanted patients with recurrent hepatitis C virus has been shown to be lower than of patients transplanted for other indications. Antiviral therapy in this patient population is generally recommended, but indication, optimal timing, dose and duration of therapy are not clearly defined. There are two major indications of therapy in that patients: pre-transplant antiviral therapy aiming to prevent reinfection, and post-transplant therapy with the goal of eradicating the recurrent infection. The first is limited by poor tolerance and drug side effects, and the second achieves only sustained virologic response in 25-45% of patients. Combination therapy with PEG INF and ribavirin showed the better results. Dose reduction and interruption of therapy occurs in 30 to 60% by side effects. There are no prospective randomized trials with confidence of results. More efficacious and better tolerable antiviral therapies are needed.
