Abstract

SUMMARY. There is a close relationship between chronic kidney disease (CKD) and obesity. Obesity affects kidney function through mechanisms of chronic inflammation, dysregulation of adipokines, activation of the renin-angiotensin-aldosterone system, and intrarenal lipid accumulation.

The aim – to assess changes in the lipid profile and dynamics of the adipokine – resistin and their relationship in patients with early stages of chronic kidney disease associated with obesity.

Material and Methods. 300 рatients with CKD were examined. Patients were divided into 4 groups: the first group consisted of 70 patients with the first stage CKD with normal body weight, the second group consisted of 72 patients with the second stage CKD with normal body weight; the third group consisted of 70 patients with the first stage CKD and obesity, and the fourth group consisted of 88 patients with the second stage CKD and obesity. The control group consisted of 30 practically healthy individuals. All participants had their BMI measured, and glomerular filtration rate (GFR) was calculated using CRD-EPI equations based on creatinine, cystatin C, and their combination (CRD-EPIcysC/cr) (ml/min/1.73 m²). The level of cystatin C, CRP, resistin, TNF-α in blood serum was determined by enzyme-linked immunosorbent assay. The level of total cholesterol, low-density lipoproteins, and high-density lipoproteins was determined by the colorimetric method.

Results. Resistin levels were higher in groups of patients with CKD and obesity. Resistin levels increased in cases of decreased GFR in patients of groups III and IV. In patients of groups III and IV, a direct correlation of medium strength was found between resistin and the WHR. In patients with CKD and obesity, as renal function decreased, an increase in triglyceride and LDL levels was observed, as well as an increase in pro-inflammatory cytokines, such as TNF-α and CRP, especially in patients with stage II CKD and obesity. High LDL and triglyceride levels correlate with both high resistin levels and higher low-grade inflammation in patients of groups III and IV.

Conclusions. In patients with CKD and obesity, increased levels of resistin have been found, which are inversely correlated with glomerular filtration rate. Also, in patients with CKD and obesity, high levels of LDL and triglycerides have been found in the blood serum, which correlate with both high levels of resistin and higher indicators of low-grade inflammation.
