title: [Good virological response to pegylated interferon alfa monotherapy of chronic hepatitis C infection in hemodialysis patient].
abstract: Liver disease caused by hepatitis C virus infection is associated to significant morbidity and mortality among patient with end stage renal disease on maintenance hemodialysis (HD). Therapy in these patients consists of Interferon, preferably pegylated Interferon (pIFN), thus Ribavirin (RBV) is not recommended for patients with impaired renal function, outside its use in controlled trials. We report a case of 35 years young woman on HD treatment, renal transplantation candidate with chronic hepatitis C virus infection, HCV RNA positive (by PCR), genotype 3a, moderate viral load, light increase of aminotransferases. Pegylated Interferon alfa-2a (135 mcg/weekly/SC) was initiated. She achieved HVC RNA negative within 12 weeks, following with pINF as monotherapy to complete 24 weeks (6 months). Sustained virologic response persisted to 24 and 48 weeks. Most important side effects were light detriment of anemia, moderate neutropenia and thombocytopenia, transitory elevation of transaminases and "flu-like" syndrome. Adverse events were well tolerated with total compliance with pIFN dose, no requiring reduce or stop the treatment. These findings confirm that hemodialysis patients with chronic hepatitis C respond well to pegylated IFN monotherapy and a long-term sustained virologic response is achieved, appears to be better tolerated with less side effects, so combination therapy with pINF plus ribavirin is not necessary in all cases.
