Abstract

The annual meeting of the French GTI (Transplantation and Infection Group) focused on donor-derived infections (DDIs) in solid organ transplant (SOT) recipients. Given the ongoing organ shortage, rigorous donor screening is essential to detect potential infectious risks. Donor evaluation should include medical history, travel, vaccination status, serologies, and exposures. Various pathogens are of concern, including viruses (HIV, hepatitis, BK polyomavirus), multidrug-resistant bacteria, fungi, and emerging arboviruses like West Nile virus and dengue. HIV-positive donor to HIV-positive recipient (D+/R+) transplantations are increasingly accepted, with promising outcomes. Hepatitis E (HEV) is now the most common viral hepatitis and may lead to chronic infection in SOT recipients, requiring ribavirin treatment. Non-Candida fungal infections, though rare, are associated with high mortality and demand early recognition. Climate change and globalization are expanding the range of vector-borne infections, necessitating seasonal and regional screening. BK polyomavirus remains a major complication in kidney transplant recipients, and monitoring viral load is critical. Bacterial infections from donors are uncommon but should be evaluated based on site, organism, resistance profile, and treatment history. Overall, maintaining safety in transplantation requires constant vigilance, updated knowledge, and personalized risk-benefit analysis to adapt to emerging infectious threats-especially amid ongoing organ scarcity.

Keywords: Bk virus; HIV; chronic hepatitis; donor-derived infection; non-candida derived fungal infection.
