Abstract:
ObjectiveTo undertake a controlled, prospective study to investigate the relationship between serum resistin level and blood sugar, blood lipids and thyroid hormone in patients with hyperthyroidism. Methods Clinical data of 50 patients with hyperthyriodism were collected from 2008 to 2009 in department of endocrinology the Second Hospital of Harbin Medical University. All patients were newly diagnosed cases that received no medication. At the same time, 40 healthy persons underwent physical examination in the hospital were taken as control group. Diabetes, obesity, hypertension, and high cholesterol were excluded from the two groups. Serum resistin level was determined using ELISA method. Chemiluminescence was used to check the levels of fasting insulin, free triiodothyronine (FT3), free thyroxin (FT4), and thyroid stimulating hormone (TSH). Glucose oxidase method determination-peroxidase-anti-peroxidase(GOD-PAP) was used to check the levels of fasting blood-glucose.Cholesterol oxidase method was used to check the levels of total cholesterol(T-CH). Glycerol-phosphate oxidase was used to check the levels of triglyceride(TG). Enzymes colorimetric method was used to check high density level of lipoprotein cholesterol(HDL-C) and low density level of lipoprotein cholesterol (LDL-C), and the height, weight,waist circumference, and hip circumference were measured. Body mass index (BMI) and insulin resistance index (HOMA-IR) were calculated. Groups were compared using t test and correlation analysis using Pearson correlation test, and the relationship between serum resistin level and blood sugar, blood lipids and thyroid hormone were analyzed using multiple linear stepwise regression analysis method. Results Serum glucose[(5.2 ± 0.7)mmol/L],resistin concentrations[(132.1 ± 41.3)μg/L], FT3[(19.8 ± 8.7) pmol/L], FT4[(54.1± 29.6)pmol/L], fasting insulin levels[(7.9 ± 2.8)mU/L] and HOMA-IR(2.3 ± 1.0) were significantly higher compared with controls group [(4.7 ± 0.5)mmol/L, (65.1 ± 5.9)μg/L, (4.1 ± 0.6)pmol/L, (14.3 ± 2.2)pmol/L, (6.4 ± 2.7)mU/L, (1.5 ±1.2); t =4.64, 10.17, 11.42, 8.49, 4.48, 9.42, P＜ 0.01 or ＜ 0.05)]. T-CH[(3.7 ± 0.8) mol/L], LDL-C[(1.8 ±0.6)mol/L], TSH[(0.01 ± 0.01 )mU/L] were significantly lower compared with controls group[(4.6 ± 0.7)mol/L,(2.3 ± 0.7)mol/L, (1.80 ± 0.90)mU/L; t =5.30, 3.33, 14.48; all P＜ 0.01)]. Pearson correlation analysis showed that resistin and FT3, FT4 and HOMA-IR was positively correlated, respectively (r =0.719, 0.790, 0.396, P ＜ 0.01or＜ 0.05), resistin and T-CH and LDL was negatively correlated, respectively(r =- 0.364, - 0.519, P ＜ 0.05or ＜ 0.01). Multiple linear regression analysisshowed that resistin and FT3, FT4, and HOMA-IR was positively correlated, respeetively(r =0.756, P ＜ 0.01 ). Conclusion Resistin and FT3 and FT4 are related. Resistin might play important roles in insulin resistance and glucose and lipid metabolism disorders in patients with hyperthyriodism.
