Black LKDs Have Higher HTN Risk

HYPERTENSION IS more likely to develop in Black vs White living kidney donors (LKDs), investigators reported at the National Kidney Foundation’s 2023 Spring Clinical Meetings in Austin, Texas.

Using data from the Scientific Registry of Transplant Recipients, Ekamol Tantisattamo, MD, MPH, of the University of California Irvine in Orange, California, and colleagues retrospectively studied 174,359 LKDs who donated a kidney from June 1972 to September 2022. The cohort had a mean age of 41 years, and 70% were White, 11% Black, 13% Hispanic, and 3% Asian.

The incidence rate of systolic hypertension (130 mm Hg or higher) was 0.02 person-months. On multivariate analysis that adjusted for age, gender, predonation obesity status and other potential confounders, Black donors had a significant 17% higher risk for systolic hypertension compared with White donors, the investigators reported in a poster presentation. Asian donors had a significant 15% lower risk for systolic hypertension compared with White donors. Other races and ethnicities had no significant difference in risk. ■
