Early post-liver transplant use of direct-acting antivirals in naïve and NS5A inhibitor-experienced HCV patients.

Direct-acting antiviral drugs (DAA) are safe and effective in the HCV population. However, in patients with decompensated cirrhotics and/or active hepatocellular carcinoma or relapse to NS5A-inhibitors, response rates are lower and DAA therapy must be postponed until after liver transplant in an era of organ shortage and suboptimal donors. We aimed to assess the prevalence of patients still HCV infected at time of transplantation over the last 3 years in our Center and describe the safety and efficacy of DAA therapy started as soon as possible after surgery. We enrolled all HCV viremic patients transplanted in our Centre from January 2019 to March 2022. The follow-up was closed in July 2022. Among 490 liver transplants, 49 (10%) patients were still HCV viremic at opeation, 43 naïve to DAA and 6 were NS5A-experienced. Median donor age was 64 years; donor risk index 1.8. In naïve patients sofosbuvir/velpatasvir was started after a median time of 1 day from surgery, while in NS5A-experienced sofosbuvir/velpatasvir/voxilaprevir after 14.5 days (p=0.001). Response rate was 98%. 1 NS5A-experienced patient experienced acute cholestatic hepatitis which promptly reverted after permanent DAA discontinuation. Hence very early post-liver transplant HCV eradication was safe and effective thanks to a close teamwork which involved anesthesiologists, transplant surgeons and hepatologists.
