A prospective multicenter pilot study of HIV-positive deceased donor to HIV-positive recipient kidney transplantation: HOPE in action

HIV-positive donor to HIV-positive recipient (HIV D+/R+) transplantation is permitted in the United States under the HIV Organ Policy Equity Act. To explore safety and the risk attributable to an HIV+ donor, we performed a prospective multicenter pilot study comparing HIV D+/R+ vs HIV-negative donor to HIV+ recipient (HIV D-/R+) kidney transplantation (KT). From 3/2016 to 7/2019 at 14 centers, there were 75 HIV+ KTs: 25 D+ and 50 D- (22 recipients from D- with false positive HIV tests). Median follow-up was 1.7 years. There were no deaths nor differences in 1-year graft survival (91% D+ vs 92% D-,P = .9), 1-year mean estimated glomerular filtration rate (63 mL/min D+ vs 57 mL/min D-,P = .31), HIV breakthrough (4% D+ vs 6% D-,P > .99), infectious hospitalizations (28% vs 26%,P = .85), or opportunistic infections (16% vs 12%,P = .72). One-year rejection was higher for D+ recipients (50% vs 29%, HR: 1.83, 95% CI 0.84-3.95,P = .13) but did not reach statistical significance; rejection was lower with lymphocyte-depleting induction (21% vs 44%, HR: 0.33, 95% CI 0.21-0.87,P = .03). In this multicenter pilot study directly comparing HIV D+/R+ with HIV D-/R+ KT, overall transplant and HIV outcomes were excellent; a trend toward higher rejection with D+ raises concerns that merit further investigation.
