Abstract

Background: Intravascular hemolysis in sickle cell anemia could contribute to complicate associated with nitric oxide deficiency, advancing age, and increased mortality. We have previoulsy reported that intense hemolysis is associated with validated in other populations. Methods: The distribution of serum lactic dehydrogenase (LDH) values was used as a surrogate measure of intravascular hemolysis in a contemporaneous patient group and historical adult population from the Cooperative of Sickle Cell Disease (CSSCD), all with sickle cell anemia. Chronic hyper-hemolysis was defined by the top LDH quartile and was compared to the lowest LDH quartile. Results: Hyper-hemolysis subjects had higher systolic blood pressure, higher prevalence of leg ulcers (OR 327.95% Cl 1.92-5.53, P
