Current Situation of Solid Organ Transplantation from HIV-Positive Donors to HIV-Positive Recipients in Europe. The Spanish Perspective.

Objectives: There is limited information on the use of organs from HIV-positive donors (HIV D+) for HIV-positive recipients (HIV R+) in Europe. In some countries the use of HIV D+ organs is prohibited by law. This study aimed to assess the attitudes of Spanish kidney and liver transplant (KT/LT) teams towards HIV D+/R+ KT/LT through a nationwide survey, and to evaluate the current situation across Europe regarding legislation and reported cases.

Methods: In 2018 and 2019, two surveys were conducted across Spain's 24 LT and 39 KT centres, respectively. Specialists in HIV/infectious diseases, nephrology/hepatology, urology/liver surgery and transplant coordination completed a questionnaire, with responses analysed by speciality. We also consulted European representatives on national legal frameworks regarding HIV D+/R+ and conducted a narrative review of published cases (2000-2025).

Results: The Spanish survey was answered by at least one member of all Spanish LT and KT teams (63/63, 100%). Most specialists who responded to the survey (167/252; 66%) supported using organs from HIV D+ virologically suppressed (VS) on ART, high-risk and serodiscordant couples, but not from non-VS HIV D+, for HIV R+. All respondents endorsed implementing a dedicated consent form, and a majority expressed willingness to participate in an HIV D+/R+ trial. No major differences were observed between LT and KT teams. At the European level, the use of organs from HIV D+ was permitted, prohibited or unregulated in 6 (17%), 11 (31.5%) and 18 (51.5%) countries, respectively. Ten HIV D+/R+ transplants (six kidneys and four livers) have been published, with good one-year outcomes.

Conclusions: The surveyed Spanish specialists would agree on using organs from VS HIV D+ for HIV D+/R+ transplants. This procedure is only legally allowed in very few European countries. These results should promote changes in donor laws across Europe.
