Overview Nitric oxide is an important inflammatory mediator produced from arginine by nitric oxide synthase.Nitric oxide has a multitude of functions which could impact favorably on vaso-occlusion in sickle cell disease.Oral arginine has been shown to raise levels of nitric oxide. This study will test whether daily oral arginineresults in an increase in nitric oxide and other beneficial effects in patients with sickle cell disease. The results ofthis study will serve as the basis for further clinical trials to determine if daily arginine is a beneficial therapy forpatients with sickle cell disease.
Focus Areas 1. To assess the physiological effects (both beneficial and deleterious) of the administrationof oral arginine in patients with SCD.
2. To evaluate the effect of daily oral arginine on clinical vaso-occlusive events in SCDpatients.
Outcomes 1. Efficacy will be determined by changes in three laboratory parameters which will serve assurrogates for potential clinical benefit: nitric oxide, Gardos channel activity, and RBC density.
2. sVCAM, Nitrotyrosine, 8-iso-PGF2a, Ektacytometry, endothelin-1, fetal hemoglobin (HbF) and echocardiogram results as well as clinical outcomes including hospitalizations, ER visits, and painmedication use.
