Abstract
Background and study aimsHepatitis C virus (HCV) prevalence inchronic kidney disease (CKD) patients is significantly higher than in the general population. This study evaluated the efficacy and safety of combined ombitasvir/paritaprevir/ritonavir-based therapy in HCV patients with renal impairment. Patients and methodsOur study included 829 patients with normal kidney functions (group 1) and 829 patients with CKD (group 2),which were subdivided into patients not requiring dialysis (group 2a) and those on hemodialysis (group2b). Patients received regimens of ombitasvir/paritaprevir/ritonavir with or without ribavirin or sofosbuvir/ombitasvir/paritaprevir/ritonavir with or without ribavirin for 12 weeks. Clinical and laboratory assessment was done before treatment, and patients were followed up for12 weeks after treatment. ResultsThe sustained virological response (SVR) at week 12 was significantly higher in group 1 than in the other three groups/subgroups, being 94.2% vs 90.2%, 90%, and 90.7%, respectively. The regimen with the highest SVR was ombitasvir/paritaprevir/ritonavir with ribavirin. The most common adverse event was anemia, which was more common in group 2. ConclusionOmbitasvir/paritaprevir/ritonavir-based therapy in chronic HCV patients with CKD is highly effective, with minimal side effects despite ribavirin-induced anemia.
