Reports on the outcome of treatment for hepatitis C virus (HCV) infection in dialysis patients are limited by small patient series, nonrandomized study designs, and few case-control studies. We reviewed 2 meta-analyses (Meta-1 and Meta-2) published in 2008, which analyzed sustained viral responses (SVR), adverse effects, and reasons for discontinuing treatment. Meta-1 analyzed the results obtained in 645 patients and Meta-2 the results in 459 patients (19 studies were duplicated). The overall SVR was 40%; the SVR in genotype 1 was 33%, with pegylated interferon providing few additional benefits over conventional interferon. Adverse events were reported in <50% of cases compiled in the meta-analyses. A high percentage of anemia was documented, although the use of erythropoietin, intravenous iron administration, or transfusions was not generally reported. A typical flu-like syndrome occurred in 41% of patients, requiring withdrawal of antiviral treatment in 11%. Severe adverse events were divided into the following groups: hormonal (thyroid): bone pain; cytopenia; gastrointestinal; immunological (prior graft rejection); central nervous system; cardiovascular; and infectious problems. The authors of the meta-analyses pointed out bias in the selection of candidates for treatment, limitations related to the number and type of adverse effects and their clinical evaluation, and in the cases of discontinuation of treatment or loss to follow-up. Additional studies reporting individual patient data are needed because the paucity of controlled studies limits generalization of the results to the population of dialysis patients.
