Advances in our understanding of the pathogenesis of autosomal dominant polycystic kidney disease (ADPKD) have opened up possibilities of new therapies to prevent disease progression. High quality clinical investigations in patients with ADPKD, however, pose significant challenges to investigators including limited access to patients with ADPKD,insufficient guidance by experienced investigators and lack of resources to conduct these studies.

The Polycystic Kidney Disease Research Clinical and Translational Core (P30) aims to establish an infrastructure that will assist investigators in designing and conducting highest quality clinical and translational research focused on a diverse group of patients with ADPKD.

Objective 1: To establish a Mid-Atlantic cohort of ADPKD patients (N=200) with baseline clinical phenotyping performed at the General Clinical Research Unit of the University of Maryland School of Medicine.

Objective 2: To establish a state-of-the-art biobank of specimens from the ADPKD cohort including serum, plasma,urine and DNA.

Objective 3: To develop a collaborative network of physicians and practices in the Mid-Atlantic region who will contribute to the ADPKD cohort and will be willing to refer patients for future studies and trials.

Objective 4: To establish a web-based registry of ADPKD patients in the Mid-Atlantic area.

Further study details as provided by University of Maryland:

Primary Outcome Measures:
  • Renal volume by MRI [ Time Frame: Baseline ] [ Designated as safety issue: No ]
    Calculations of the volume will be based on summation of the products of the area measurements of the kidneys and/or liver and slice thickness. A region-based signal threshold method will be applied to calculate total cyst volume, and the remaining parenchymal renal and hepatic volume.

Secondary Outcome Measures:
  • Quality of Life: [ Time Frame: Annually up to 4 years ] [ Designated as safety issue: No ]
    Self-reported Quality of Life (pain, anxiety, depression, physical activity, fatigue).

Other Outcome Measures:
  • Hospitalizations [ Time Frame: Annually up to 4 years ] [ Designated as safety issue: No ]

Biospecimen Retention:   Samples With DNA

Plasma, serum,urine, and DNA will be collected at the baseline visit and stored in a biorepository.

Estimated Enrollment: 200
Study Start Date: March 2013
Estimated Study Completion Date: June 2015
Estimated Primary Completion Date: June 2015 (Final data collection date for primary outcome measure)
