Abstract

ESRD is a major complication in young adults with sickle cell anemia. As more patients with sickle cell anemia reach the third and fourth decades of life, the incidence of clinically apparent renal insufficiency will increase. As we understand the pathophysiology of renal damage and the effects of various therapies on the sickle renal vasculature, we can tailor specific management without further compromising already impaired renal function. Diagnostic clues must be recognized prior to the onset of irreversible damage, with appropriate intervention initiated at each age group. Bone marrow transplantation (BMT) is the only available cure for SCA at the present time. The demonstration that several distinct haplotypes of the beta s gene cluster on chromosome 11 influence the clinical expression of sickle cell anemia may be useful in delineating children who are at high risk for severe disease, and hence candidates for such hazardous therapeutic interventions as BMT prior to onset of clinically discernable disease. Current BMT preparative regimens can produce renal cortical and pulmonary toxicity, posing a patient selection problem in those cases in which the vasculopathy of the major organs is at an early stage and might be potentially repairable. Gene therapy without toxic preparative regimens is the ultimate answer. The challenge for the near future is the development of effective early therapeutic intervention during childhood and young adulthood.
