Consortium for Radiologic Imaging Studies of Polycystic Kidney Disease (CRISP) II

The Division of Kidney Urology and Hematology Disease (DKUHD) of the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) funded a cooperative agreement (UO1) for a consortium of participating clinical centers (PCCs) and a data coordinating and imaging analysis center (DCIAC) to develop and implement studies to test whether imaging techniques can provide accurate and reproducible markers of progression of renal disease in patients with polycystic kidney disease.

The awarded participating clinical centers are Emory University, University of Kansas, and Mayo Foundation (with a subcontract to the University of Alabama). The awarded DCIAC is Washington University in St. Louis. Due to the relocation of the DCIAC P.I. from Washington University to the University of Pittsburgh, the DCIAC for CRISP II is located at the University of Pittsburgh.

The goal of the CRISP Study is to conduct a prospective, longitudinal trial to evaluate the accuracy and validity of magnetic resonance imaging to determine disease progression in ADPKD defined as a change in both renal and renal cyst volumes and renal function over time.

Observational Model: Cohort
Time Perspective: Prospective

Retention:   Samples With DNA

blood, urine

Non-Probability Sample

Participants who are diagnosed with ADPKD between the ages of 15 and 45 with risk factors (2/3 of the study population) or without risk factors (1/3 of the study population)for progression to ESRD with relatively normal renal function were be eligible for recruitment into the CRISP I study. The objective of the recruitment process was to identify ADPKD participants with the appropriate level of renal function who are either at high or low risk for progression to ESRD, who will be available for the entire follow-up period and who are likely to be compliant with the study protocols and visit schedules.
