Endocan Levels in Children with Polycystic Kidney Disease

Abstract

Objective: Autosomal dominant polycystic kidney disease (ADPKD) is a common renal disorder that is characterized by hypertension and renal failure. Recently, it has been emphasized that endocan which is an endothelial dysfunction biomarker, could increase in many renal diseases. High endocan levels have also been reported in hypertensive ADPKD adult patients with renal failure. However, studies are limited on children. In this study, we investigated the serum endocan levels in normotensive ADPKD children with normal renal function. Material and Methods: The study consisted of 20 ADPKD children without hypertension and renal failure as a patient group, and 20 healthy age- and sex-matched children as a control group. Serum endocan levels were determined by enzyme-linked immunosorbent assay techniques and compared between the two groups. Results: The mean age of patients was 9.9±4.12 years, and the mean age of the control group was 10.2±3.83 years. There was no significant difference between the two groups in terms of gender, age, and BMI (p=0.751, p=0.813, p=0.781, respectively). The leukocyte (p=0.449), hemoglobin (p=0.337), platelets (p=0.134), serum uric acid (p=0.671) and serum creatinine (p=0.074) levels, eGFR (p=0.459) were not significantly differed between groups. The mean serum endocan level in the PKD group was 345.8±169.5 pg/ml, and in the control group was 448.61±258.2 pg/ml. Serum endocan levels did not change between groups (p=0.159). Conclusion: Unlike the adult ADPKD patients, this study suggested that serum endocan level was normal in children with ADPKD without hypertension and renal failure.
