Study on regulation of adipokines on body fat distribution and its correlation with metabolic syndrome in type 2 diabetes mellitus

Monocyte/macrophage-specific soluble CD163 (sCD163) concentration is associated with insulin resistance and increases with deteriorating glycemic control independently of BMI. This led to the proposal of the hypothesis that obesity-associated white adipose tissue inflammation varies between individuals. The objective was to examine the effect of male overweight/obesity and type 2 diabetes mellitus (T2DM) on associations between adiposity parameters and sCD163. A total of 23 overweight/obese non-diabetic men, 16 overweight/obese men with T2DM, and a control group of 20 normal-weight healthy men were included. Body composition and regional body fat distribution were determined by whole-body dual X-ray absorptiometry scan and abdominal computed tomography (CT) scan. Serum sCD163 concentrations were determined by ELISA. Associations between adiposity parameters and sCD163 were investigated using multiple linear regression analysis. In the normal-weight healthy men, there was no significant association between adiposity parameters and sCD163, whereas in the overweight/obese non-diabetic men, measures of general and regional adiposity were positively associated with sCD163. In the overweight/obese men with T2DM, only visceral adipose tissue (VAT) and the ratio of VAT to abdominal subcutaneous adipose tissue (SAT), a measure of relative body fat distribution between VAT and SAT depots, were positively associated with sCD163. In a multivariate analysis, including VAT, upper-body SAT, and lower-body fat, adjusted for BMI and age, VAT remained a significant predictor of sCD163 in the overweight/obese T2DM men, but not in the overweight/obese non-diabetic men. Our results indicate that VAT inflammation is exaggerated in men with T2DM, and that propensity to store excess body fat viscerally is particularly detrimental in men with T2DM.

Evaluation of people at increased risk like first degree relatives of type 2 diabetes mellitus (FDRDM) may be useful to reduce the risk of disease progression, development, early intervention, and to take precautionary measures. By considering the multifactorial pathophysiological changes of D.M., we have examined the body fat distribution, cardiorespiratory fitness, and lipid profile of FDRDM. Similar age, height, waist-hip ratio (WHR) in both groups, significantly higher body mass index (BMI) in FDRDM, was observed in our study. Percentage body fat and blood glucose levels in fasting were elevated considerably, and 12 min walk distance was low in FDRDM. Visceral fat was slightly high, but it was not statistically significant. In FDRDM, High-density lipoproteins (HDL) were less but not statistically significant. Significantly higher levels of Total cholesterol (T.C.), triglycerides (TGL), low-density lipoproteins (LDL), and very-low-density lipoproteins (VLDL) were seen high in FDRDM when compared to controls. Higher body fat percentage reduced cardiorespiratory function and abnormal lipid profile in FDRDM may lead to the development of severe cardiovascular events and necessitates lifestyle modification at early phases of disease development.
