RESUMO
The objective of the study was to assess the efficacy of antiviral therapy in patients with hepatitis C virus (HCV) recurrence after liver transplantation (OLT). We included 30 patients of mean age 56 years, who experienced HCV recurrence after OLT. Mean time from OLT to the beginning of therapy was 57 months (median: 43 months). All of them were on monotherapy: tacrolimus (n = 21), cyclosporine (n = 6), and mycophenolate mofetil (n = 3). Fourteen had previously been diagnosed with allograft HCV cirrhosis. Patients were treated with peginterferon alpha 2b (1.5 mug/kg/weekly SC) and ribavirin (10.6 mg/kg/d) for 48 (genotypes 1, 4) or 24 weeks (genotypes 2, 3). After a mean follow-up of 20 months, two patients had died due to biliary sepsis (while on therapy) and acute myocardial infarction (7 months after the end of therapy). End of treatment virological response was achieved in 19 patients (63.3%) and sustained virological response (SUR) in 14 (46.7%). Comparing cirrhotic and noncirrhotic patients, SVR was achieved in seven patients in both groups (50% vs 43.8%; P = .732). Every patient had some adverse event; in 11 patients (36.7%) it was withdrawn (seven cirrhotic and four noncirrhotic; P < .05), and in 12 the starting dose was decreased (40%). There were neither rejection episodes nor cirrhotic complications during therapy, but infections were more common in cirrhotic patients (57% vs 25%; P < .05). In HCV cirrhotic transplanted patients the sustained virological response to combined antiviral therapy was similar to that in noncirrhotic patients, but severe adverse events including infections were much more common.
