Background:
The development of effective direct-acting antiviral treatment (DAAT) for hepatitis C virus (HCV) has opened the possibility of using HCV+ donors. We aimed to assess the long-term feasibility of lung transplantation using organs from HCV+ donors.
Methods:
We used the UNOS database to evaluate adult lung transplant recipients between 2000 and 2023. HCV+ organs were further divided into those positive for both antibody and nucleic acid testing (NAT) or antibody testing alone. Baseline recipient and donor characteristics were compared. The Kaplan-Meier method was used to assess 30-day, 1-year, and 5-year survival. We performed risk analyses using multivariate Cox regression analyses.
Results:
41,797 lung transplants were performed, among which 945 used HCV+ donors. Recipients of HCV+ lungs had higher FEV1 (P < .001), older (P < .001), and had higher BMI (P < .001). While 5-year survival did not differ between recipients of HCV+ and HCV- donor lungs (P = .093), graft survival was superior among recipients of HCV+ lungs (P = .038). Acute rejection rates were also lower for recipients of HCV+ lungs (P = .018). However, recipients of HCV+ lungs required significantly higher time on the ventilator post-transplant (P = .033). Donor HCV+ status, regardless of whether they were NAT- (HR 1.03, P = .766) or NAT+ (HR 0.89, P = .24), was not associated with adverse outcomes.
Conclusions:
Lung transplantation with HCV+ donor lungs demonstrates promising outcomes up to 5 years post-transplant. With careful preoperative screening, DAAT treatments, and postoperative management, recipients of HCV+ lungs may expect minimal additional complications.
