Summary

Black patients experienced significantly higher graft failure rates after living related donor (LRD) kidney transplants compared to white patients. These disparities persisted even after adjusting for confounding factors, indicating complex underlying causes beyond genetics.

Area of Science:

  • Nephrology
  • Transplantation immunology
  • Health disparities

Background:

  • Racial and ethnic disparities in kidney transplant outcomes are a significant concern in the United States.
  • Understanding the factors contributing to these disparities is crucial for improving patient care and graft survival.

Purpose of the Study:

  • To investigate the association between race/ethnicity and outcomes in living related donor (LRD) renal transplantation.
  • To adjust for potential confounding variables that may influence race-based differences in transplant success.

Main Methods:

  • Prospective analysis of 14,617 patients undergoing LRD renal transplantation from the UNOS Renal Transplant Registry (1988-1996).
  • Utilized Cox proportional hazards model for multivariable adjustment of genetic, social, and demographic factors.

  • Examined the impact of HLA matching on graft survival in different racial groups.

    • Main Results:

    • Black recipients had a 1.8 times higher likelihood of graft failure compared to white recipients (P < 0.01, RR = 1.77).
    • After adjusting for confounding variables, the risk of graft failure for Black recipients remained elevated at 1.7 times (P < 0.01, RR = 1.65).
    • Neither genotypic nor phenotypic HLA matching improved graft survival outcomes in Black patients.

    Conclusions:

    • Racial disparities in LRD renal transplant outcomes persist, with Black recipients experiencing lower graft survival.
    • Adjusting for matching and rejection did not eliminate these disparities, suggesting non-HLA or socioeconomic factors play a role.
    • Further research into non-biocompatibility mechanisms is warranted to address racial differences in renal transplantation.
