Abstrakt: | Background: Chronic kidney disease (CKD) leading to kidney failure and end stage renal disease (ESRD) is a common health problem associated with wasting syndrome characterized by inadequate nutrient intake and decrease tissue anabolism and/or catabolism. In CKD adipokines, especially leptin and adiponectin (ADPN), accumulate in serum due to reduced renal clearance. Although, rapidly growing, knowledge of adipocytokines is limited and much is still unknown of the altered adipocytokine pattern in patients with impaired renal function. The aim of this study is to assess the adipocytokines, leptin, and adiponectin in relation to weight loss in pediatric patients with CKD stage-5 treated conservatively (CT) or undergoing maintenance hemodialysis (MHD). Methods: 41 CKD stage-5 patients and 20 healthy controls were included in this study. Serum levels of leptin and adiponectin were determined by ELISA. Leptin gene expression was analyzed using quantitative real time-polymerase chain reactions (QPCR). Results: Patients had significantly elevated ADPN levels and non significantly elevated serum leptin levels as compared to controls (p < 0.001, p = 0.354, respectively). Leptin gene expression and body mass index (BMI) were highly significantly reduced in CKD stage-5 compared to controls (p < 0.001 for each). There were no significant differences between patients treated conservatively and those undergoing MHD with respect to all studied parameters. Finally, univariate logistic regression analysis revealed no association between leptin, ADPN, and weight loss in CKD stage-5 patients. Conclusions: The present study showed non significantly elevated or even normalized serum leptin levels, elevated serum adiponectin level and reduced leptin gene expression in CKD stage-5 patients as compared to healthy controls. Patients had significantly lower weight than healthy controls but there was no association between leptin, adiponectin, and weight loss in CKD stage-5 studied patients so, further studies are needed to clarify the role of the two adipokines in body weight loss in those patients. |
