RESUMEN
BACKGROUND AND AIMS: Hepatitis C virus (HCV) infection is a frequent complication among long-term dialysis patients. The aim of the present study was to evaluate the efficacy and side effects of pegylated interferon-α(2a) (PEG-IFN-α(2a)) treatment in hemodialysis patients. METHODS: We retrospectively reviewed charts of 16 HCV-RNA-positive hemodialysis patients. RESULTS: There were 11 male and 5 female patients treated with dialysis for 6-28 years. Twelve patients had HCV genotype 1b, 2 patients had 3a, and 1 patient had genotype 2a. Although only 10 out of 16 patients completed 48 weeks of treatment, early virological response and end-of-treatment virological response were achieved in 9 and 13 patients, respectively. Sustained virological response was recorded in 9 patients. The most common side effect was anemia. A flu-like syndrome was documented in 6, myalgia in 4, and arthralgia in 5 patients. Rectorrhagia, endocarditis and severe cough were recorded in 1 patient each. Nine patients received a renal transplant, and all 6 responders remained HCV-RNA-negative. CONCLUSIONS: PEG-IFN-α(2a) has limited efficacy in dialysis patients. A significant proportion of patients discontinued treatment because of side effects. Additional studies with long-term follow-up are needed to determine the optimal treatment of HCV infection in the dialysis population.

Myopathy and rhabdomyolysis are rare adverse effects of treatment with hydroxymethylglutaryl-coA reductase inhibitors. The risk of adverse effects is increased with the concomitant use of statin and specific drugs that can induce myopathy, in patients with liver and renal function impairment, hypothyroidism and diabetes mellitus. The clinical picture of rhabdymyolysis with acute renal failure caused by the use of simvastatin in a 54-year-old patient with diabetes mellitus and hypertension is described.
