Brief Summary:
There are substantial data demonstrating increased endothelial dysfunction, inflammation and oxidative stress in patients with Autosomal dominant polycystic kidney disease (ADPKD), the association between serum uric acid level and endothelial dysfunction has not been elucidated yet in these patients. Therefore, in this study, the investigators aimed to examine the relationship between the uric acid level and the ED in normotensive ADPKD patients with preserved renal function.

Condition or disease
Polycystic Kidney, Autosomal Dominant

Detailed Description:
This is the first study to evaluate the relationship between uric acid and endothelial dysfunction in patients with early stage ADPKD

Study Type : Observational
Actual Enrollment : 150 participants
Observational Model: Cohort
Time Perspective: Cross-Sectional
Official Title: Endothelial Dysfunction in Patients With Polycystic Kidney Disease

The study evaluated the association of serum uric acid levels with endothelial dysfunction in early ADPKD patients with normal renal function

Primary Outcome Measures :
  1. Measurement of asymmetric dimethylarginine (ADMA) and flow mediated dilatation (FMD) [ Time Frame: 4 months ]
    ADMA,FMD and uric acid measurements were performed to determine endothelial dysfunction in ADPKD patients
