          Abstract

          Background: Since hemodialysis (HD) patients usually suffer from multiple clinical problems and drug side effects, the treatment of hepatitis C in these patients still remains a challenging problem. Methods: We identified eligible studies using a wide-spectrum search up to May 2007 in MEDLINE (since 1966) and EMBASE (since 1980). Two researchers (S.M.H.M. and M.R.) independently reviewed the manuscripts identified by the search strategy. To determine the most current information, only studies that had been published after 1995 were included. Results: Interferon (IFN)-α has long been used for this purpose; however, more recently the advent of pegylated (PEG) IFN has proven to be more beneficial in these patients. Even though the usage of ribavirin is promising in the case of hepatitis C in otherwise healthy subjects, the utilization of this drug in patients with renal failure may be accompanied by catastrophic complications. Conclusion: Although both conventional IFN and PEG-IFN seem to be favorable options for the management of hepatitis C in HD patients, further studies on new therapeutic agents are required.

              Evidence that clearance of hepatitis C virus RNA after alpha-interferon therapy in dialysis patients is sustained after renal transplantation.

              To date, there is no available treatment of hepatitis C virus (HCV) infection after renal transplantation (RT). Among 55 anti-HCV-positive/HCV RNA-positive hemodialysis patients who were treated with IFN-alpha (9 MU/wk during 6 or 12 mo), 21 of them (38%) had a sustained virologic response. Of these, 16 (76%) underwent RT 38 mo (range, 2 to 57 mo) after alpha-IFN therapy. There were 13 men and 3 women aged 46 yr (range, 27 to 68 yr). At RT, HCV serology was still positive in 15 patients, and HCV viremia was negative in all patients. Immunosuppression relied on anticalcineurin agents with or without steroids and/or antimetabolites; in addition, 12 of them received induction therapy with antithymocyte globulins. At the last follow-up after RT, at 22.5 mo (range, 2 to 88 mo), HCV viremia remained negative in all patients. Moreover, HCV RNA was not present in peripheral blood mononuclear cells when assessed in eight patients. HCV serology was found to be still positive in 13 patients. Three patients presented with acute rejection, one presented with a suppurative lymphocele, one died from a sepsis, and four presented with a cytomegalovirus infection. None of them developed posttransplant diabetes mellitus. In conclusion, hemodialysis patients waiting for a RT need to be treated with alpha-IFN because when HCV RNA clearance occurred, they experienced no relapse after transplantation despite chronic immunosuppressive treatment.
