title: Demographic and clinical characteristics of patients with autosomal dominant polycystic kidney disease: a multicenter experience.
abstract: OBJECTIVE
  Autosomal dominant polycystic kidney disease (ADPKD) is the most common hereditary kidney disease. It accounts for 5-10% of patients with end-stage renal disease (ESRD). The aim of this multicenter study was to investigate the demographic and clinical characteristics of patients with ADPKD.
  
  
  METHODS
  1,139 patients with ADPKD who were followed up at 12 different centers were recruited for this study. The investigated demographic and clinical characteristics were gender, age, smoking history, educational status, the existence of hypertension, hematuria, urinary tract infection, urinary tract stones and renal replacement therapy. Patients were considered as hypertensive if they were taking antihypertensive medications or if they had blood pressure (BP) of 140/90 mm Hg or greater. If the patients were currently on antihypertensive drugs, the classes of these agents were noted.
  
  
  RESULTS
  548 male and 591 female patients were included and the mean age at initial diagnosis was 37.1 ± 16.3 years. 20.3% were current smokers whereas 15% were ex-smokers. The mean systolic and diastolic BPs were 136.1 ± 29.8 and 84.9 ± 17.8 mm Hg, respectively. 63.7% used antihypertensive drugs and 73.1% of those used renin-angiotensin system blockers. 11.8% had ESRD, of which 75.8% were treated with hemodialysis.
  
  
  CONCLUSIONS
  This study showed that hypertension is the most common (72.6%) clinical finding in ADPKD patients in Turkey and renin-angiotensin system blockers are widely used.
