Potential pool of cardiothoracic organs from donors with HIV

BACKGROUND: Under the HIV Organ Policy Equity (HOPE) Act, transplants from donors with HIV to recipients with HIV (HIV D+/R+) have been largely limited to kidney and liver. However, recent modifications to HOPE research guidelines allow broader participation of cardiothoracic programs. METHODS: To quantify potential cardiothoracic HOPE donors, we used Scientific Registry of Transplant Recipients (SRTR) data (3/2016-12/2024) to identify 101,200 donors without HIV and 273 HOPE donors (with true and false positive HIV tests). Using logistic regression, we predicted the probability of having a heart or lung(s) used for transplant among donors without HIV that had a kidney or liver used. We then applied model parameters to HOPE donors that had a kidney or liver used to estimate the number of HOPE donors that might have been cardiothoracic donors if the practice were expanded. RESULTS: Among donors without HIV, cardiothoracic donation was associated with age, cause of death, hepatitis C, hypertension, diabetes, smoking, cardiovascular disease, blood gas, and circulatory death. Applying our model, an estimated 41.0% (N = 111), 18.7% (N = 51), and 15.2% (N = 41) of HOPE donors were potential heart, any lung (single or double), or double-lung donors, as compared to 32.3%, 21.8%, and 18.2% of abdominal organ donors without HIV, respectively. This translated to an annual 13-18 potential heart and 5-8 potential lung transplants (of which 4-6 would be double-lung transplants) from HOPE donors. CONCLUSIONS: If HIV D+/R+ is more widely expanded to cardiothoracic transplantation, 41% of HOPE kidney and liver donors have the potential to donate a heart and almost 20% to donate a lung to candidates with HIV.
