Abstract

Introdution: Adiponectin is a peptide secreted from fat cells that plays an important role in the development of insulin resistance and type 2 diabetes. A number of single nucleotide polymorphisms in the adiponectin gene are associated with lower adiponectin expression and T2DM. The aim of this study was to determination the frequency of rs 2241766 polymorphism in adiponectin gene and its relation with adiponectin level, insulin resistance, type 2 diabetes and in pre diabetes/diabetes and healthy individuals.
Methods: This study was performed in a case -control method. 73 prediabetic/diabetic patients with fasting blood sugar >100 mg/dl was selected as the case group without drug history, and 76 individuals with FBS 70-100 mg/dl as the control group. Biochemical and anthropometric variables were measured by standard methods and the levels of adiponectin and insulin hormone were measured using commercially available human ELISA kit. The determination of genotyping was done using PCR-RFLP method. Data were analyzed by SPSS software version 19.
Results: Regression analysis showed that polymorphism rs2241766 in the adiponectin gene has no significant relation with diabetes and insulin resistance. No significant difference was found between TT and TG carriers for any of the variables in the two groups (pre diabetes/diabetes and Non-diabetic). A negative correlation was seen between adiponectin and insulin resistance ( r=-0.225, p< 0/01).
Conclusion: According to this study, adiponectin gene polymorphism rs2241766 is not associated with adiponectin levels, insulin resistance and type 2diabetes, but there was a correlation between adiponectin and insulin resistance.

Abstract


Introduction: Obesity, results in a number of serious complications, such as type 2 diabetes, non-alcoholic fatty liver disease and metabolic syndrome. The levels of blood of adiponectin and cortisol have been associated with obesity. This study aimed to investigate the relationship of adiponectin and cortisol levels with obesity and biochemical parameters.
Methods: This case-control study was conducted only on men, 80 participants with body mass index (BMI)≥25 considered as case group, and 100 participants with BMI<25 as control group in the Research Institute for Endocrine Sciences, Shahid Beheshti University of Medical Sciences. Plasma levels of adiponectin and cortisol were measured through ELISA kit and other variables were determined by standard methods. Data were analyzed using SPSS software version 16. P-values <0.05 were considered as significant.
Results: Our findings showed no significant difference in cortisol level between individuals with BMI≥25 and individuals with BMI<25. Obese men had significantly higher levels of triglycerides, systolic and diastolic blood pressure and lipid profiles whereas, adiponectin and high-density lipoprotein-cholesterol (HDL-C) levels were lower compared to the control group (p-value<0.05). In this study, an inverse correlation was observed between adiponectin and fasting blood glucose (FBS), and also BMI. It was found a positive correlation between cortisol and cholesterol and also FBS.
Conclusion: The results show that there is no relationship between cortisol and obesity, but a negative correlation between adiponectin levels and obesity.

Abstract

Introduction: Non-alcoholic fatty liver disease (NAFLD) is a major global health problem, in which liver fat exceeds 5% of the liver weight, without secondary causes of fat accumulation or excessive alcohol consumption. Resistin plays a key role in energy homeostasis, insulin resistance, inflammation, and metabolic disorders. This study aimed to investigate the relationship between resistin (RETN) level and NAFLD.
Methods: In this cross-sectional study, 80 patients with NAFLD and 80 healthy individuals as controls were evaluated. Biochemical variables, liver enzymes, insulin, and resistin were measured. Data were analyzed using SPSS version 16 software.
Results: The variables of cholesterol, insulin, triglyceride, HDL, body mass index, age, and liver enzymes were significantly different between the two groups of patients with NAFLD and healthy individuals (p<0.05). In patients, resistin was associated with triglyceride (r=0.243, p=0.045). No association was found between resistin level and NAFLD grades (p≥0.05).
Conclusion: The results of this study indicate that there is a relationship between resistin and NAFLD. There is no association between resistin level and the degree of NAFLD.
