چکیده انگلیسی
The objective of the present study was to evaluate serum level of copper, zinc, iron and metabolic parameters in postmenopausal women with diabetes. A total of 413 postmenopausal women were enrolled in the current study. Women were divided into 4 groups with equal age and body mass index according to glycated hemoglobin (HbA1c) levels (â¤5.5; 5.5-6.0; 6.0-6.5; >6.5%). Serum Fe, Cu, and Zn levels were assessed using inductively-coupled plasma mass-spectrometry. Blood HbA1c, serum glucose, insulin, C-reactive protein (CRP), ferritin, and ceruloplasmin (Cp) were assessed using commercial kits. Homeostatic model assessment insulin resistance (HOMA-IR) and transferrin (Tf) saturation were calculated. The obtained data demonstrate that every 0.5% increase in HbA1c levels from 5.5% is associated with a significant elevation of glucose, insulin, CRP, and HOMA-IR values. Diabetic patients were characterized by significantly higher Fe (11%), Cu (8%), and Zn (6%) levels as compared to the controls. At the same time, the overall trend to increased metal levels in association with HbA1c was detected only for Fe (p < 0.05) and Cu (p < 0.05). Serum ferritin levels in diabetic women was 3-fold higher than in the controls, whereas Tf saturation was decreased by 35%. Serum Cp levels were significantly increased by 19% in prediabetes, whereas in diabetic postmenopausal women no such increase was observed. A significant elevation of total metal concentration in diabetic subjects without a concomitant elevation of transport proteins may be indicative of increased levels of “free” Fe and Cu, known to be toxic.
