Introduction

Obesity has emerged as a public health crisis in many populations including Sudanese. Adipose tissue produces several adipokines, one of them is adiponectin which has attracted much attention because of its antidiabetic and antiatherogenic effects. Adipose tissue is a key endocrine organ that communicates with brain, muscle, liver, and pancreas, thereby maintaining energy homeostasis. The communication between adipose tissue and other organs is mainly mediated by multiple endocrine substances secreted by adipose tissue, referred to as “adipocytokines 1. Changes in the levels of adipocytokines are suspected to be indicators of dysfunction in adipose tissue 2,3. Adiponectin 4 and resistine hormones are thought to link with obesity and MS with cardiovascular risk. Adipose tissue is no longer considered an inactive organ, which only stores lipids and serves as an energy reservoir. These chemical messengers, known as ‘adipocytokines’ or ‘adipokines’, include tumor necrosis factor α (TNF-α), adiponectin, leptin, resistine and virstatin 6. Adiponectin is an adipocyte-secreted polypeptide hormone with molecular weight 30 kDa (244 amino acids) which modulates several metabolic processes, and regulates insulin sensitivity and energy homeostasis, as well as glucose and lipid metabolism 7. The hormone plays a principal role in the suppression of the metabolic derangements that may result in insulin resistance, obesity, MS, and cardiovascular disease 5, 7, 8. Adiponectin is a protective protein with antidiabetic, anti-inflammatory and anti-atherogenic effects 6. Reduced plasma adiponectin levels have been reported in obese individuals, particularly in those with visceral obesity, and have been negatively correlated with insulin resistance. Recent evidence has also suggested the role of adiponectin in the regulation of insulin action, energy homeostasis, obesity, and insulin resistance. Circulating adiponectin levels and adiponectin gene expression in adipose tissue are reduced in patients with type 2 diabetes 9–10. Available data suggest that adiponectin might reduce hepatic glucose production and increase muscle glucose utilization, perhaps by increasing fat oxidation and thereby reducing circulating NEFA levels and intramyocellular accumulation 11. Studies of adipocytokines in populations with different propensity for obesity, insulin resistance, type 2 diabetes and atherosclerosis are needed, and are interesting in this respect, because they have very high incidence of insulin resistance, central obesity, type 2 diabetes, and cardiovascular disease 12–13. In a previous study by Valsmakis et al 14, South-Asians have lower adiponectin levels compared to Caucasians. It was not clear however, if this feature of the South-Asians is related to aspects of glucose metabolism. No published data have been found related to adipocytokines, resistine and obesity in Sudanese population   This study aims to determine the relationship between body fat distribution and adipocytokines.

Materials and methods

In this is a descriptive cross-sectional and analytical case-control study. The study was done in Khartoum state. The target population is a total 205 Sudanese females were recruited to participate in this study, classified according to WHO body mass index (BMI) Classification, aged 20-50 years. The sample size calculations were based on the formula for unmatched case-control studies. Open EPI-INFO statistical package version 7 was used with 99 % two-sided confidence level, 80% power and 40 % of controls exposed, 57 % of cases exposed and odds ratio > 2. The ratio of controls to cases is 1:1. Venous blood sample (5 ml) was drawn by a well-trained medical technologist into vacutainer tubes, blood collected in anticoagulant fluoride oxalate and then plasma samples were obtained by centrifugation at room temperature at 3000 rpm/10 minutes. BMI was obtained by anthropometric measurements, including height and weight, were taken using standard protocols. BMI was calculated as weight (in kilograms) divided by height (in meters squared).

Estimation of Fasting Blood Glucose

Plasma levels of blood glucose were measured using the particle-enhanced immunoturbidimetric assay method Cobas C-311®. Human glucose agglutinates with latex particles coated with monoclonal anti-glucose antibodies, and then, the precipitate was determined turbidimetrically.

Estimation Adiponectin and Resistine

For Adiponectin and Resistine used ELISA Kits-(ab222508)/ (ab222403) is a single-wash 90 min sandwich ELISA designed for the quantitative measurement of Adiponectin and Resistine in plasma. Simple step ELISA® technology employs capture antibodies conjugated to an affinity tag that is recognized by the monoclonal antibody used to coat our Simple step ELISA® plates.15

Statistical analysis

Finally, the result analyzed by SPSS version 24. The mean and SD were obtained, and one way ANOVA are used for comparison. Linear regression was also use for correlation. P. value was obtained to assess the significance of the results (P value of < 0.05 was significant).

Discussion

Obesity is a modifiable risk factor in the development of type 2 diabetes mellitus (T2DM), with the prevalence of both increasing worldwide 4 and the risks of many complications and comorbidities (e.g., cardiovascular disease and chronic kidney disease) are considerably increased in patients with T2DM who have concomitant obesity. through this study, we have shown that circulating adipocytokine concentrations differed based on the degree of obesity in females’ patients with diagnosed T2DM, we demonstrated that higher plasma concentrations of FBG, Resistine and lower plasma concentrations of adiponectin were present in patients diagnosed T2DM who were overweight, obese and sever obesity than in patients diagnosed T2DM who had underweighted and healthy weight. According to results of this study observed significant difference in resistine concentration was identified between patients with T2DM who had underweight, healthy weight and those who were overweight, obese and sever obesity. Foula WH et al found that resistine concentrations were higher in obese females patients with diabetes than non-obese females participants; moreover, they were higher in obese patients with diabetes than in non-obese healthy controls 1,5,7 .Observed from this study significant difference in adiponectin concentration was identified between patients with T2DM who had underweight, healthy weight and those who were overweight, obese and sever obesity  Serum adiponectin concentrations have been shown to be inversely correlated with the severity of insulin resistance in patients with T2DM 3 consistent with the findings of previous studies 9,10 the present study showed that a lower level of adiponectin was present in patients with diagnosed T2DM who were obese than in those who had underweight and healthy weight BMI. Adiponectin is considered to have anti-diabetic and anti-inflammatory effects; therefore, it is reasonable to presume that patients with T2DM who obese exhibit more severe insulin resistance status are than patients with T2DM who have underweight and healthy weight BMI. Some of the studies have suggested that adiponectin/resistine ratios are more closely related to the severity of insulin resistance 11,12. It became clear through this study positive correlation between the levels of serum resistine and Fasting Blood Glucose. While on the other side of the study it was observed negatively correlation with these same parameters. In conclusion, serum resistin and adiponectin levels are correlated with the occurrence of insulin Resistance females T2DM 13,14.

Conclusion

Our findings suggest that, in patients diagnosed T2DM, adipocytokine concentrations (resistine, and adiponectin) differed between patients who had normal BMI and those who were obese. This study concluded that BMI effected on Adipocytokines levels and Increased risk of insulin resistance in females with Type2 diabetes by increased the level of Resistine, Fasting Blood Glucose and reduced of Adiponectin in different groups of BMI.
