Sickle-cell trait: novel clinical significance.
There is a long-standing controversy in the literature as to whether sickle-cell trait (SCT) should be viewed as a benign carrier state or as an intermediate disease phenotype. Because SCT is routinely detected by neonatal screening for sickle-cell disease, it becomes imperative that consensus on this issue be achieved in order to provide the best medical advice to affected individuals. The issue of selective screening in the post-neonatal period was thrust into the limelight recently by the National Collegiate Athletic Association's recommendation that its member colleges and universities test student-athletes to confirm their carrier status if not already known. The stated goal of this recommendation was to prevent exercise-related sudden death in athletes with SCT. We review some of the reported complications of SCT for which new information has emerged, focusing particularly on venous thromboembolism and renal manifestations.
