Clinical study on autosomal dominant polycystic kidney disease among North Tunisians

Abstract

Autosomal dominant polycystic kidney disease (ADPKD) is the most common hereditary renal disease, which usually manifests in adulthood. It is characterized by the development of multiple cysts in the kidneys and many other extrarenal manifestations. We aimed to determine the factors that contribute to the progression of ADPKD to end-stage renal disease (ESRD). In a retrospective multicentric study, we reviewed the records of 569 patients with ADPKD, hospitalized at a nephrology department or followed up at the outpatient department of university and regional hospitals, covering the north and center of the country, during the period 1969–2016. The mean age of the study patients was 48.54 ± 13.68 years and 14% were young adults (40 years (P = 0.009), hematuria (P = 0.034), hemoglobin >14 g/dL (P = 0.0013), high uric acid level (P = 0.001), and leukocyturia (P = 0.02). Death occurred in 59 cases (10.3%), mostly caused by infections (44.1%). In our study, ADPKD was lately diagnosed in most cases. Family screening is important, which will enable early detection and management of the complications associated with ADPKD.
