Evaluation of Growth-differentiation Factor-15 Level and few Physiological Parameters Patients with Diabetes Mellitus Type 2

Abstract

The study included 90 subjects and is divided into two groups: The first group is the patient group, which consists of 45 patients with diabetes mellitus type two; 45 patients with diabetes mellitus type two were identified by specialized diabetes doctors by samples collection in outpatients clinic at Diabetes and Endocrine Center in Marjan Medical City in Hilla city, Babylon province from 1 November 2022 till 31 Januray 2023. The blood samples of this study were obtained from patients and controlled through drug 5 mL of blood by using medical sterile syringes from a brachial vein and placed in a gel tube and ethylenediaminetetraacetic acid (EDTA) tube. Then the gel tube was placed at room temperature for 30 minutes to coagulate the blood, and samples were centrifuged (3000 rpm/min) for 5 minutes to separate the serum from other components of the blood. The serum was withdrawn by micropipette and then placed in the eppendorf tubes in two repeaters and kept frozen at -20℃ for the determination of growth differentiation factor 15 (GDF 15), lipid profile and fasting blood glucose. The whole blood in the EDTA tube to determine HbA1C. The mean fasting blood sugar and hemoglobin A1c of diabetes patients is significantly higher at (p-value < 0.001) than that of controls. Diabetes patients had a significantly higher of serum lipid profile than the controls. Therefore, the mean of cholesterol, triglyceride, and low-density lipoprotein (LDL) and very low-density lipoprotein (VLDL) was highly significant (p < 0.001). The mean concentration of GDF-15 of patient groups was significantly increased than those matched groups of healthy control at (p < 0.001). In addition, the results also showed a highly significant increase (p < 0.001) in the mean of GDF-15 for the patient’s males and females in comparison with the control’s males and females. The correlation results indicated a statistically significant positive correlation in diabetic group between GDF-15 vs. FBS (r = 0.572, p = < 0.001) and HbA1c (r = 0.576, p = < 0.001). Positive non-significant correlations were demonstrated between GDF-15 vs. cholesterol (r = 0.131, p = > 0.05), triglyceride (TG) (r = 0.167, p = > 0.05), LDL (r = 0.38, p = > 0.05) and VLDL (r = 0.136, p = > 0.05). Negative non-significant correlation was between GDF-15 and high-density lipoprotein (HDL) (r = 0.137, p = > 0.05).
