Background: Hepatitis C virus [HCV] infection is associated with more significant morbidity and mortality among dialysis patients than in healthy populations. The fixed-dose tablet [ombitasvir/ paritaprevir/ritonavir] in combination with ribavirin was effective and generally well tolerated in treatment of chronic HCV infected patients with end stage renal disease [ESRD] on hemodialysis. However, limited published data are known about the usefulness of this regimen for treatment of HCV patients with ESRD on hemodialysis. Aim of the work: The aim of this study was to evaluate the safety and efficacy of treatment regimen of ombitasvir [OBV] 25 mg /paritaprevir [PTV] 150 mg /ritonavir [RTV] 100 mg plus generic ribavirin [RBV] 200 mg in Egyptian HCV-infected naive patients with ESRD on regular hemodialysis. Patients and methods: A prospective cohort study involved 40 chronic HCV on regular hemodialysis patients, who were eligible for treatment with combined oral antiviral therapy. Results: The results showed that thirty-five patients [35/40[87.5%]] completed 12 weeks of HCV therapy; they had a virological response at end of therapy and sustained virological response. Anemia was the main observed side effect which lead to discontinuation of the treatment in five patients [12.2%]. As these patients were not responding to anemia correction measures [blood transfusion, erythropoietin-stimulating agents, and modification of RBV dose]. Conclusion: OBV/PTV/RTV plus Ribavirin can be used in treatment of chronic HCV patients with ESRD on regular hemodialysis.
