Renal Transplantation in HIV-positive and HIV-negative People With Advanced Stages of Kidney Disease: Equity in Transplantation.

Background: People with HIV are at a greater risk of end-stage kidney disease than the general population. Considering the risk of death after end-stage kidney disease, access to renal transplantation in people with HIV is critically important.

Methods: We included all adult patients on chronic dialysis in Ontario, Canada, between 1 April 2007 and 31 December 2020. We determined the probability of kidney transplantation with competing risk of death over time since the initiation of dialysis by calculating the adjusted subdistribution hazard ratios (sdHR; 95% confidence interval [CI]). We also compared long-term renal allograft and posttransplant mortality outcomes between HIV-negative and HIV-positive persons.

Results: Of 40 686 people (median age, 68 years; interquartile range, 57-77; 38.4% women), 173 were HIV-positive and 40 513 were HIV-negative. The incidence of kidney transplantation in HIV-negative and HIV-positive patients was 40.5 (95% CI, 39.4-41.6)/1000 person-years and 35.0 (95% CI, 22.8-53.7)/1000 person-years, respectively ( = .51). Considering the competing risk of death, HIV-positive people had a significantly lower chance of receiving kidney transplants than HIV-negative people (sdHR, 0.46 [95% CI, .30-.70]). The long-term allograft failure risk was not significantly different between HIV-negative and HIV-positive people, considering the competing risk of posttransplant death (sdHR, 1.71 [95% CI, .46-6.35]).

Conclusions: Although the incidence and crude probability of kidney transplantation were similar among HIV-negative and HIV-positive persons in this cohort, those with HIV had a significantly lower likelihood of kidney transplantation than those without HIV. Having HIV was not significantly associated with a poor long-term allograft outcome compared with patients without HIV.
