Kidney Transplants and HIV: What the Numbers Show

People living with HIV often face a higher chance of their new kidney being rejected, yet scientists have not fully figured out why. One theory points to the hidden HIV viruses that linger in the body, called the latent viral reservoir (LVR). These dormant copies could disrupt the immune system and spark inflammation, potentially leading to rejection. To investigate this idea, researchers followed kidney transplant patients with HIV for a year. They measured the size of the LVR at the start and again after 52 weeks, using a specialized DNA test that can detect intact viral copies. The study included patients who received kidneys from donors with HIV and those whose donors were HIV‑negative.The results were surprising. The amount of hidden virus did not differ between patients whose kidneys were rejected and those who kept their transplants. This held true regardless of whether the donor had HIV or not. These findings suggest that the presence of dormant HIV is unlikely to be a major factor in transplant rejection. They also reinforce the growing evidence that kidneys can safely be shared between people with HIV, opening more options for patients who need a new organ. The study was part of a larger clinical trial registered under NCT03500315. It adds valuable data to the conversation about how best to support people with HIV who need kidney transplants.
