Abstract: Chronic hepatitis C virus infection (HCV) has a negative impact on the long-term survival of recipients of kidney transplants. HCV should be treated in hemodialyzed patients before their enlistment for kidney transplantation in order to avoid the reactivation of virus after transplantation. Direct-acting antivirals represent the current standard of care in hemodialyzed patients with HCV genotypes 1 and 4; in patients with genotypes 2 or 3, the optimal regimen is yet to be established. Sofosbuvir (SOF) and daclatasvir (DCV) represent an antiviral pangenotypic regimen with favorable pharmacokinetics in hemodialyzed patients. We retrospectively evaluated safety and efficacy of the combination of SOF and DCV in the treatment of genotype 3a chronic HCV in six male patients (mean age of 39 years, range 25–53 years) with end-stage renal disease on maintenance hemodialysis; these patients were treated with a reduced dose of SOF (one half of a 400 mg tablet) and 60 mg of DCV once daily. The anticipated treatment duration was 12 weeks. Initial HCV RNA ranged from 120,000 to 11,000,000 IU/mL. Two of the six patients had compensated liver cirrhosis based on shear-wave elastography result. All of the patients completed a 12-week treatment. Viremia became negative on treatment and remained negative 12 weeks after the end of therapy in all the patients. All of them (6/6, 100%) achieved sustained virological response, including two with cirrhosis and two with HCV RNA >6,000,000 IU/mL. The treatment was well tolerated: none of the patients presented with a serious adverse event requiring hospital admission and none had anemia or any significant changes in blood count. One patient had a short period of diarrhea, which was resolved with antibiotic treatment. The combination of reduced-dose SOF and full-dose DCV, daily, was a safe and effective treatment in our group of hemodialyzed patients infected with HCV genotype 3.
