Abstract

Data outside of clinical trials with direct-acting antiviral regimens with or without ribavirin as treatment of chronic hepatitis C virus in solid organ transplant recipients are limited. Liver transplant (LT), kidney transplant (KT), and dual liver kidney (DLK) transplant recipients from the Hepatitis C Therapeutic Registry and Research Network database, a multicenter, longitudinal clinical care treatment cohort, treated with direct-acting antiviral regimens between January 1, 2014, and February 15, 2016, were included to assess safety and efficacy. Included were 443 posttransplant patients (KT = 60, LT = 347, DLK = 36); 42% had cirrhosis, and 54% had failed prior antiviral therapy. Most had genotype (GT) 1 (87% with 52% GT1a, 27% GT1b, and 8% GT1 no subtype) and were treated with sofosbuvir (SOF)/ledipasvir ± ribavirin (85%) followed by SOF + daclatasvir ± ribavirin (9%) and ombitasvir/paritaprevir/ritonavir + dasabuvir ± ribavirin (6%). Rates of sustained virologic response (SVR) at 12 weeks were available on 412 patients, and 395 patients (95.9%) achieved SVR at 12 weeks: 96.6%, 94.5%, and 90.9% among LT, KT, and DLK transplant recipients, respectively. Ribavirin did not influence SVR rates and was more often used in those with higher BMI, higher estimated glomerular filtration rate and lower creatinine. Female gender, baseline albumin ≥3.5 g/dL, baseline total bilirubin ≤1.2 mg/dL, absence of cirrhosis, and hepatic decompensation predicted SVR at 12 weeks. Six episodes of acute rejection (n = 2 KT, 4 LT) occurred, during hepatitis C virus treatment in 4 and after cessation of treatment in 2. Conclusion: In a large prospective observational cohort study, direct-acting antiviral therapy with SOF/ledipasvir, ombitasvir/paritaprevir/ritonavir + dasabuvir, and SOF plus daclatasvir was efficacious and safe in LT, KT, and DLK transplant recipients; ribavirin did not influence SVR, and graft rejection was rare.
