The objectives of CRIC are to improve understanding of the relationship between CKD and CVD and to examine traditional and non-traditional ("uremia-related")) risk factors for progression of CKD and CVD among patients with reduced kidney function. The study, which started in 2001, is a prospective observational cohort study of approximately 3,000 men and women with CKD. This is the largest cohort study of CKD undertaken. A wide range of measurements are performed on CRIC Study participants including creatinine clearance and iothalamate measured glomerular filtration rate. Cardiovascular measures include blood pressure, ECG, ABI, ECHO, and EBCT. Clinical CV outcomes include MI, ischemic heart disease-related death, acute coronary syndromes, congestive heart failure, cerebrovascular disease, peripheral vascular disease, and composite outcomes.

The CKiD Study is a NIH-funded, multicenter, prospective cohort study of children aged 6 months to 16 years with mild to moderate impaired kidney function. The specific aims of the CKiD study are to: (1) identify novel and traditional renal disease risk factors for the progression of CKD (i.e., decline of GFR) in children; (2) characterize the impact of a decline in kidney function on neurodevelopment, cognitive abilities, and behavior; (3) identify the prevalence and evolution of cardiovascular disease risk factors in children with CKD, and; (4) examine the effects of declining GFR on growth and the treatment of growth failure, and to assess the consequences of growth failure on morbidity in children with CKD.

The Clinical Islet Transplantation (CIT) Consortium is a network of clinical centers and a data coordinating center conducting studies of islet transplantation in patients with type 1 diabetes. Studies conducted by the CIT Consortium will focus on improving the safety and long-term success of methods for transplanting islets, the insulin-producing cells of the pancreas, in people whose own islets have been destroyed by the autoimmune process that characterizes type 1 diabetes.
