Summary
This is a prospective clinical cohort study that involves a baseline study visit followed by up to 3 annual follow-up study visits for a total follow-up of 36-48 months to evaluate the age- and sex-adjusted rate of change in kidney function, and to identify biomarkers of endothelial function, metabolomic profiles and clinical characteristics for the worsening of kidney function and for a rapid decline in kidney function.

Description
Sickle cell disease is a severe monogenic disorder which affects approximately 80,000 patients in the US. It is characterized by a vasculopathy with involvement of multiple organs and resulting in complications such as ischemic stroke, pulmonary hypertension, autosplenectomy, priapism, as well as chronic kidney disease (CKD). Despite the high prevalence of CKD and its known association with increased mortality, the natural history of CKD and the factors associated with changes in kidney function in patients with SCD remain incompletely defined. Furthermore, the available treatment options for albuminuria, an early manifestation of CKD, in patients with SCD are limited. In fact, no controlled studies have confirmed the long-term efficacy of angiotensin-converting enzyme (ACE) inhibitors, the current "standard of care." There is increasing evidence for a contribution of endothelial dysfunction to the pathophysiology of albuminuria in SCD. The association of biomarkers of endothelial function with albuminuria provides opportunities, not only to assess the effect of therapies which improve endothelial function, but also to evaluate the predictive value of these biomarkers for a decline in kidney function. The long-range goal is to develop a model to identify patients at particularly high risk for a decline in kidney function.
In this study, the investigators will evaluate rate of change in kidney function (decline in estimated glomerular filtration rates and increase in albuminuria) and identify biomarkers of endothelial function, metabolomic profiles and clinical characteristics for the worsening of kidney function and for a rapid decline in kidney function. At the conclusion of this proposed work, the investigators will have an improved understanding of the natural history of CKD in sickle cell anemia. With the limited available therapies for the treatment of albuminuria in SCD and the paucity of data on the long-term efficacy of available pharmacotherapies, identification of biomarkers for the progression of CKD will facilitate the development of treatments which may be more effective than the current "standard of care."
