Brief summary (registry, in English)
Chronic kidney disease (CKD) is a silent epidemic affecting more than 37 million Americans. The burden of morbidity and mortality associated with CKD derives from its frequent progression to end-stage kidney disease (ESKD) and the disproportionate risk of cardiovascular disease (CVD) and associated complications. CKD is strongly and independently associated with CVD, even after adjustment for traditional CVD risk factors. This led to the hypothesis that other risk factors augment the rate of CVD in the setting of CKD. Hence, many patients with progressive renal disease succumb to fatal CVD events before they need renal replacement therapy. The National Institute of Diabetes, Digestive, and Kidney Diseases (NIDDK) established the Chronic Renal Insufficiency Cohort (CRIC) Study in 2001 with the initial goal of elucidating the relationship between CKD and CVD. Since its inception, the CRIC Study has recruited and followed a racially and ethnically diverse cohort of over 5,000 participants with reduced kidney function from 13 clinical recruitment sites across the US. The original aim of CRIC was to establish a clinical research laboratory designed to (a) identify novel predictors of CKD progression, and (b) characterize the manifestations of CVD and identify its risk factors among individuals with CKD. The CRIC Study has examined a broad set of etiological factors (clinical, behavioral, and biomarker-associated) potentially responsible for both progressive CKD and CKD-related morbidities, especially those early in the course of CKD. Characterizing relationships between these risk factors and outcomes should facilitate identification of high-risk subgroups with CKD and guide enrollment into preventive treatment trials and application of preventive therapies. Over time, the scientific focus and the CRIC investigator network have broadened extensively through a highly successful ancillary studies program that has included more than 100 projects, most of which have been funded through federal grants. To date, the CRIC Study's investigative activities have resulted in over 300 published scientific papers with many additional manuscripts in development.

Other
- Unable or unwilling to provide informed consent
- Known cirrhosis
- Pregnant or breast-feeding women
- Currently participating in an interventional clinical trial (i.e., primarily trials of therapeutic agents that may have an effect on renal or cardiovascular outcomes).
- Institutionalized (e.g., prisoner, nursing home resident, skilled nursing facility resident)
- Appears unlikely or unable to participate in the required study procedures as assessed by the investigator, study coordinator or designee.
Who the study is looking for
- During the screening visit a blood sample will be tested to indirectly check kidney function based on the serum creatinine level:
- Age Range: 21 - 79 years
- Estimated Glomerular Filtration Rate (GFR): 45 - 70 mL/min/1.73m²
- Proteinuria: varies dependent on eGRF
Age in the registry: 21 years to 79 years · Sex: All · Does not accept healthy volunteers
