BOSTON — Hepatitis C infection was prevented or rapidly cured in transplant recipients who received organs from donors infected with the virus following combined treatment with ezetimibe and direct-acting antiviral therapy, according to study results presented at The Liver Meeting 2019.

“Unfortunately, most of you know that the opioid epidemic continues and, with that, an overdose crisis,” Jordan J. Feld, MD, MPH, FAASLD, from the University of Toronto University Health Network, said during a press conference. “What has been observed is that among potential organ donors, particularly those who died of overdose, the prevalence of hepatitis C has increased dramatically.”

During the study period, transplant specialists considered donors infected with HCV for lung, heart, kidney or kidney-pancreas recipients.

To test the possibility of preventing HCV infection, recipients received Mavyret (glecaprevir/pibrentasvir, AbbVie) with ezetimibe 6 hours to 12 hours before transplantation and then daily for 1-week posttransplant.

“Ezetimibe is a cholesterol-lowering drug that is approved and quite safe, but also happens to be a ligand ... for one of the entry factors that hepatitis C uses to enter hepatocytes,” Feld explained.

Of the 13 recipients without HCV who received HCV-infected organs, four developed quantifiable viremia posttransplant with a maximum HCV RNA of 2.96 log 10 IU/mL. HCV RNA declined rapidly and was unquantifiable by day 4 after transplant in all patients.

Six other patients had detectable but unquantifiable HCV RNA at day 1 posttransplant which was undetectable by day 2 in five patients and by day 4 in one patient.

All four patients with quantifiable HCV RNA received kidney or kidney-pancreas transplants, but no other factors correlated with posttransplant viremia. Additionally, Feld reported no relapses to date with a median follow-up of 10.2 weeks (range, 1-12.1 weeks).

Medication was well-tolerated with no serious adverse events related to treatment.

“Despite the horrible tragedy of the opioid epidemic, there is some good to come from the epidemic by using these organs for others,” Feld said. “But we must also focus on what we can do about this epidemic.” – by Talitha Bennett
