Ghrelin,resistin and insulin in obese diabetic women in Wad-Madani,Sudan

BackgroundObesity in the Sudan is increasing at alarming rate with the tendency of reaching an epidemic proportion in women. It is commonly associated with type 2 diabetes (T2D). Some adipokine hormones such as resistin are associated with obesity.ObjectivesTo study how the levels of resistin, ghrelin and insulin are associated with obesity,fat distribution and (T2D) and to ascertain any interrelationships between them.Subjects and methods150 women, age ≥18 years old, resident in Wad-Madani town, Sudan were participated in the study. They were divided into 3 groups according to body mass index (BMI) value: I (normal weight), II (overweight) and III (obese diabetic). Fasting serum resistin and ghrelin concentrations were measured using ELISA method. Insulin levels were determined by radioimmunoassay(RIA).ResultsThe mean±SD levels of resistin 5.80±4.91ng/mL,Ghrelin107.60±26.67pg/M and Insulin 11.92±8.54mLU/ml in obese diabetic were found to be greater than in normal or overweight women. In normal weight values were 3.07±2.15 ng/mL 83.30±13.38pg/mL, and 6.62±6.77mLU/ml for resistini, ghrelin and Insulin, respectively. Values for overweight women 3.64±2.63 pg/mL 90±17.35 pg/mL and 8.13±7.54 mLU/ml for resistin, ghrelin and insulin respectively.Conclusions and recommendationsIncreased BMI, waist circumference (WC) and hormones (ghrelin and resistin) were associated with insulin resistance. Further studies are needed to accept or refute these findings.     

Resistin Concentration is Increased in the Peritoneal Fluid of Women with Endometriosis

Citation Yi KW, Shin J‐H, Park HT, Kim T, Kim SH, Hur J‐Y. Resistin concentration is increased in the peritoneal fluid of women with endometriosis. Am J Reprod Immunol 2010 Problem The aim of this study was to investigate the concentration of resistin and adiponectin in the peritoneal fluid (PF) of patients with endometriosis. Method of study PF sampling was obtained from women with (n = 48) and without endometriosis (n = 36), and the anthropometric indices of the patients were measured. Resistin and adiponectin concentrations in the PF were determined using the enzyme‐linked immunosorbent assay. Results The mean concentration of PF resistin was significantly higher in women with endometriosis compared to the controls. PF resistin concentrations were not associated with any of the anthropometric indices. The PF adiponectin did not differ between the two groups, but showed a significant association with the weight, body mass index, and hip circumference. After adjusting for these factors, PF adiponectin expression was not associated with endometriosis. Conclusion The findings of this study suggest a potent role for resistin in endometriosis. Further studies are needed to elucidate the biological implications of resistin in endometriosis.

The relationship between features of metabolic syndrome and blood adipocytokine concentrations in the morbid obese patients during dynamic weight loss

Bariatric surgery is the most effective method to achieve weight loss in obese subjects. The aim of this study was to evaluate some adipocytokines and insulin, as well as parameters of metabolic syndrome of the obese patients, for three and six months after vertical banded gastroplasty, in the time of dynamic weight loss. Seven males and two females aged 28 to 49 years, with long lasting simple obesity and the presence of metabolic syndrome, were studied. After surgical treatment the values of the body mass index, waist circumference, systolic and diastolic blood pressure, total cholesterol, LDL cholesterol, triglycerides, and blood concentrations of leptin decreased significantly. Before surgical operation of all obese patients no statistically significant correlations between studied parameters were noted. Three and six months later a lot of correlations between studied parameters appeared. In conclusion, (a) vertical-banded gastroplasty is a valuable method in treatment of obese subjects, leading to a significant decrease in body weight and improvement in some parameters of metabolic syndrome in a few months after surgery, (b) adipocytokines, together with an unknown gastric factor, may be key factors in the control of some features of the metabolic syndrome.
