ADPKD Cohort: Longitudinal Cohort Study of adult ADPKD patients without ESRD and eGFR>15 ml/min/1.73m 2

Study Sample (as of 3/20/2021):

  • N=198 participants enrolled
  • Age: 45.5 (13.6) years
  • 63% Female
  • 11.5% African American
  • estimated GFR: 70.9 (32.2) ml/min/1.73m 2
  • 43.6% with eGFR<60 ml/min/1.73m 2

Clinical Phenotyping
Clinical history :

  • Age of diagnosis and initial presenting symptoms (e.g., pain, hematuria)
  • History of renal and cyst complications: pain, hemorrhage, infection, rupture, stones, hematuria, and nocturia.
  • Extra-renal cysts – hepatic, pancreatic, other
  • GI complications – diverticulae, herniae (including type and surgical correction)
  • Cardiovascular complications – valvular heart disease, aortic aneurysms
  • CNS complications – including presence and size of intra-cranial aneurysms
  • Exposures – including caffeine, tobacco, iodinated contrast, hormonal therapies and oral contraception, environmental toxins
  • Non-ADPKD co-morbid conditions and medications

Family History
– Including age of ESRD of affected family members, and history of extra-renal complications including hepatic disease and intra-cranial aneurysms.
