It is just as safe and effective for people with HIV in need of kidney transplantation to get their organ from donors who are also HIV positive as it is from donors who are not infected with the virus, a new study shows. Survival rates for organ recipients one and three years after the procedure were the same for donors with or without HIV. Also the same were risks of serious side effects, such as infection, fever, and rejection in the donated organ.
In what is the largest comparative trial of the experimental procedures since the first transplant was performed in the United States in 2016, researchers at ٺƵ Health say their study findings further support formally adopting the use of organs from donors with HIV as standard clinical practice for people with HIV in need of kidney transplantation.
Spurred by a worldwide shortage of organ donors, the U.S. Congress passed the HIV Organ Policy Equity Act, or HOPE Act, in 2013, paving the way for first efforts to learn if kidney donors with HIV could safely donate to recipients who also tested positive for the virus. Nearly 90,000 Americans are on waiting lists for kidney transplantation, and those in need of a kidney transplant who are HIV positive are more than twice as likely to die while waiting than those who are HIV negative.
HIV-to-HIV transplantation has not been formally accepted as the standard of care. Concerns existed about organ recipients becoming infected with other strains of HIV, potentially leading to so-called HIV superinfection. Experts also initially feared that recipients’ need for ongoing postsurgical immunosuppression would damage either the donated organ or lead to resurgence of the recipient’s HIV viral blood counts. A serious complication in all transplantation is that the recipient’s immune system recognizes the donated organ as “foreign” and attacks it, much like it would an invading virus. For this reason, immune-suppressing drugs are used to prevent organ–transplant rejection. However, early success with HIV-to-HIV kidney transplantation alleviated these concerns.
In the study, , researchers analyzed the outcomes for 198 kidney transplantations to people with HIV at 26 medical centers across the United States from 2018 to 2021.
Results showed that for kidney transplants performed using organs from 99 donors with HIV and 99 without HIV, one-year survival rates for HIV-positive recipients were the same (94 percent and 95 percent, respectively). Three-year survival rates were also similar (at 85 percent and 87 percent). Organ rejection rates were also numerically on par after three years (at 21 percent and 24 percent.) Other measures for surgical outcomes, including the number of side effects that occurred, were also roughly the same for both groups.
While most of the study’s kidney recipients maintained viral suppression of HIV posttransplant, HIV blood counts spiked in 13 patients who received kidneys from donors with HIV. Just four such resurgent spikes occurred with organs from donors who were HIV negative. However, the researchers attributed these incidences to recipients’ not taking their antiviral medications as prescribed, and viral suppression returned with tighter adherence to drug treatment. One superinfection was detected, but with no clinical effects on the organ recipient.
“Our study demonstrates overwhelmingly that kidney transplantation from donors who are HIV positive to HIV-positive recipients is safe and effective,” said study senior investigator and transplant surgeon Dorry L. Segev, MD, PhD. Dr. Segev is vice chair in the at NYU Grossman School of Medicine and director of its . Dr. Segev also helped draft the HOPE Act and advocated for its passage. His team also performed the first HIV-to-HIV kidney transplantation at Johns Hopkins, where he worked previously.
“Thanks to the HOPE Act and this NIH-funded multicenter trial, our research offers clear evidence for moving kidney transplantation in people with HIV from the experimental phase to standard clinical practice and updating guidelines accordingly,” said Dr. Segev, who is also a professor in the Departments of Surgery and .
“These findings offer hope for the thousands of people with HIV in the United States and around the world who are in need of kidney transplantation, and to many more people where HIV infection and kidney diseases are more common,” said Dr. Segev.
The U.S. Department of Health and Human Services in September proposed to make HIV-to-HIV transplantation the standard of care for both kidney and liver donors.
Dr. Segev says more research is needed to determine the safety and effectiveness of transplanting other organs, such as the heart and lungs, from HIV-positive donors.
