Publication of the STOP trial, in which long-term blood transfusions were effective for preventing stroke in children with sickle cell anemia, was associated with a reduction in the racial disparity in stroke mortality, researchers found.
Compared with white children, black children had a greater risk of dying from ischemic stroke both before and after the trial results were announced, but the relative risk declined from 1.74 (95% CI 1.42-2.13) to 1.27 (95% CI 0.99-1.64), according to Laura Lehman, MD, of Boston Children's Hospital, and Heather Fullerton, MD, of the University of California San Francisco.
