Tuesday, November 8 (HealthDay News)-A reversal of kidney allocation policies has increased the likelihood that black patients will receive new organs from deceased donors, researchers in the United States said.
Until 2003, the United Network for Organ Sharing (UNOS) prioritized potential recipients genetically matched to deceased donors for HLA-B, an antigen involved in the body’s immune response to foreign tissues. I did. HLA-B similarities tend to be race-based.
However, this policy, combined with more white donors, meant that white patients were much more likely to undergo a dead donor kidney transplant (DDKT) than blacks.
Researchers at Johns Hopkins University School of Medicine examined data from about 179,000 patients on the kidney transplant list, while blacks were 37% less likely to receive DDKT than whites before the 2003 policy change. We found that it was 23% less after the change.
The study was published in the November issue of American Journal of Kidney Disease..
Although the gap between blacks and whites has narrowed, there remains considerable disparity, which is likely due to factors involving patients and caregivers, the researchers said.
“For example, patients may hesitate to accept a particular organ donation, and geographic disparities may be involved,” said senior author of the study, Dr. Dolly Segev, in a news release from the National Kidney Foundation. Stated.
“Another possibility is the traditional notion that African Americans are better off on dialysis than whites. If the patient or his doctor feels that dialysis works, he risks leading a transplant. More reluctant to accept. Studies This is true for older patients, but in fact it was found to be the opposite for younger patients. Young African Americans have far more dialysis than white patients. It’s bad for you, “says Segev.
Renal failure is more common among blacks (783 per million) than whites (295 per million). According to the National Kidney Foundation, nearly 90,000 Americans are currently waiting for a kidney transplant.
