Renal transplantation from seropositive hepatitis C virus donors to seronegative recipients in Spain: a prospective...

Hepatitis C virus (HCV) positive donors are identified in Spain by antibody detection (HCV-Ab) techniques while a HCV nuclear acid-testing (HCV-NAT) is not mandatory. Since it has been shown that HCV-Ab positive HCV-NAT negative donors do not universally transmit the infection, we designed a protocol based on the identification of viremia in HCV-Ab positive donors to start treatment if needed. HCV-Ab-positive donors were identified and we performed HCV-NAT immediately. Donors coinfected with HIV were excluded. Recipients with a low chance to receive a transplant, with no history of liver disease and who were negative for HCV-Ab were selected after informed consent was signed. Kidney recipients from HCV-NAT-positive donors received glecaprevir and pibrentasvir from 6 h before the transplant until 8 weeks after. Recipients from HCV-NAT-negative donors were not treated. Regular monitoring by HCV-NAT was performed to initiate antiviral treatment. We included 11 recipients from six deceased donors Four recipients received grafts from HCV-NAT-positive donors and seven patients received grafts from HCV-NAT-negative donors. None of our recipients exhibited HCV-NAT positivity during the minimum follow-up period of 6 months. Recipients from HCV-NAT-positive donors exhibited sustained virologic response at 12 weeks. One recipient from an HCV-NAT-negative donor lost his graft via a process thought to be unrelated to HCV. The remaining 10 patients had a stable functioning graft at the end of the follow-up period. Our preliminary data suggest that renal transplantation from HCV-Ab- positive donors to HCV-Ab negative recipients is safe when only the recipients of organs from HCV-NAT-positive donors are treated.
