Information on the association between obesity and initial phases of chronic kidney disease (CKD) is still limited, principally those regarding the influence of visceral adipose tissue. We investigated whether the visceral adipose tissue is more associated with reductions in glomerular filtration rate (GFR) than total and abdominal obesity in hypertensive individuals with stage 1-2 CKD. A cross-sectional study was implemented which involved 241 hypertensive patients undergoing treatment at a primary health care facility. GFR was estimated using equations based on creatinine and cystatin C levels. Explanatory variables included body mass index (BMI), waist circumference (WC), and estimated visceral adipose tissue (eVAT). The mean age was59.6±9.2years old and 75.9% were female. According to BMI, 28.2% of subjects were obese. Prevalence of increased WC and eVAT was 63.9% and 58.5%, respectively. Results from the assessment of GFR by BMI, WC, and eVAT categories showed that only women with increased eVAT (≥150 cm2) had a lower mean GFR by Larsson (P=0.016), Levey 2 (P=0.005), and Levey 3 (P=0.008) equations. The same result was not observed when the MDRD equation was employed. No association was found between BMI, WC, eVAT, and GFR using only serum creatinine. In the early stages of CKD, increased eVAT in hypertensive women was associated with decreased GFR based on cystatin C.

The Relationship

AbstractObesity and chronic kidney disease are epidemic size. Chronic kidney disease (CKD) appears to be more common in obese, although interrelation is not supported by all authors.Aim: The aim of the study was to investigate the effects of overweight and obesity on glomerular filtration rate (GFR) and the relationship between body mass index (BMI) and other risk factors for CKD.Methods: This is a cross-sectional study on 627 patients admitted in a Nephrology Department between January 2007 - December 2011. Patients were divided according to eGFR in a CKD group and a non-CKD group. Patients were divided based on BMI in: normal (<25 kg/m2), overweight (≥ 25 kg/m2 and ≤30 kg/m2) and obese (>30 kg/m2). Demographical, clinical and laboratory data (serum creatinine, lipid parameters, etc) were used for the statistical analysis. The relationship between BMI (as a marker of obesity and overweight), glomerular filtration rate and other possible risk factors for chronic kidney disease was studied.Results: 43.70% patients were obese and 33.17% overweight. CKD prevalence was 58.69%. Logistic regression analysis showed that systolic blood pressure was the main determinant of CKD in our patients.Conclusion: Lack of association between BMI and CKD was demonstrated in our study.

Background. The results of studies evaluating the levels of adiponectin, leptin and their ratios in chronic kidney disease (CKD) are conflicting. It is assumed that hyperleptinemia and changes in adiponectin clearance are consequences of a decrease in the glomerular filtration rate, they exacerbate renal impairment and may affect the prognosis of survival due to cardiovascular events. It is known that secondary hyperaparathyroidism is the most frequent complication of CKD, which not only affects calcium-phosphorus metabolism and bone tissue, but also contributes to the development of pathological processes involving other hormonal and metabolic markers. Of greatest interest is the assessment of adipocytokine levels in the development of secondary hyperparathyroidism against the background of CKD as an independent factor of increasing cardiovascular risks. The purpose of the study was to assess adipocytokine levels (adiponectin, leptin) and their ratios in patients with different stages of chronic kidney disease and their relationship with manifestations of secondary hyperparathyroidism. Materials and methods. This cross-sectional study enrolled 160 people with CKD and 40 healthy individuals as a comparison group. Results. Leptin level reduction and an increase in the proportion of patients with hypoleptinemia with a decrease in the glomerular filtration rate were found, which may be an important factor determining nutritional status. Correlations were revealed between leptin level, body mass index (ρ = 0.411) and patients’ age (ρ = 0.189), as well as between leptin/adiponectin and adiponectin/leptin ratios (ρ = 0.395 and ρ = –0.395) and body mass index in patients with CKD persisting in subgroups by stage of renal failure. A relationship was found with sex for leptin and a decrease in its levels below normal values in both men and women. Conclusions. The proportion of patients with hyperadiponectinemia was significantly higher among those with end-stage CKD compared to patients with stages 1–2. There was no statistically significant relationship between adipocytokine and parathyroid hormone levels and the presence of secondary hyperparathyroidism in patients examined.
