Prevalence of Hepatitis C Virus Infection and Efficacy of Sofosbuvir-Velpatasvir and Sofosbuvir-Daclatasvir Treatment Regimens in End-stage Renal Disease Patients on Maintenance Hemodialysis

Abstract

Patients with end-stage renal disease (ESRD) are at an increased risk of hepatitis C virus (HCV) infection. This study evaluated the prevalence of HCV infection in patients with ESRD on maintenance hemodialysis (MHD) and studied the effectiveness of sofosbuvir-velpatasvir and sofosbuvir-daclatasvir regimens in these patients. This study included patients with ESRD on MHD between January 2019 and December 2021 who were screened for HCV serology status. HCV-positive patients received sofosbuvir-velpatasvir or sofosbuvir-daclatasvir. Efficacy was assessed by the sustained virological response (SVR), and safety assessments included monitoring adverse events and laboratory parameters. Out of 1330 patients, 188 patients (14.1%) were positive for anti-HCV, with Genotype 1 being the most common genotype. Of these, 106 patients were included. The majority were males (61.3%), and the mean age was 48.4 years. Hypertension (45.3%) was the most common cause of renal failure, followed by diabetes (31.1%). Most patients (63.2%) were positive for HCV in the first 2 years of their dialysis treatment. Out of 106 patients, only 54 had received blood transfusions. Ninety-four (88.7%) patients received sofosbuvir-velpatasvir, whereas 12 (11.3%) received sofosbuvir-daclatasvir. SVR at 12 and 24 weeks after stopping treatment was seen in all (100%) patients. Asthenia and fatigue were the most common adverse events (11.2%). No patients reported on-treatment virologic failure or discontinuation of treatment because of adverse events. The prevalence of HCV infection in this population was 14.1%, and treatment of HCV infection using sofosbuvir-velpatasvir or sofosbuvir-daclatasvir regimens was well tolerated and effective.
