摘要 目的探讨2型糖尿病合并亚临床甲状腺功能减退患者的临床特点,为该类患者的治疗提供临床依据。方法选择128例2型糖尿病合并亚临床甲状腺功能减退患者作为观察组,200例甲状腺功能正常的2型糖尿病患者作为对照组,比较两组年龄、体质指数(BMI)、糖化血红蛋白(HbArC)、空腹血糖(FPG)、餐后2h血糖(2hPPG)、空腹C肽(FCP)、餐后2hC肽(2hPCP)、三酰甘油(TG)、总胆固醇(TC)、低密度脂蛋白胆固醇(LDL-C)、高密度脂蛋白胆固醇(HDL-C)、脂蛋白(a)[LP(a)]、同型半胱氨酸(Hcy)、24h尿微量白蛋白(24hUNALB)的差异。在观察组中以促甲状腺激素(TSH)10.0mU/L为切点分为两组,比较两组上述指标的差异,并分析TSH与临床指标的相关性。在TSH4.0~10.0mU/L组中,比较Hey正常和增高患者糖尿病肾病、糖尿病视网膜病变、糖尿病大血管病变发生率的差异。结果观察组和对照组BMI、FPG、FCP、TG、TC、LDL-C、LP(a)、Hey水平比较差异有统计学意义[(27.8±2.8)kg/m^2比(24.6±3.2)kg/m^2、(8.64±2.79)mmol/L比(6.71±3.65)mmol/L、(1.99±1.24)μg/L比(2.56±1.03)μg/L、(3.26±0.76)mmol/L比(2.04±0.18)mmol/L、(6.08±1.74)mmo]/L比(4.95±2.11)mmol/L、(3.86±2.01)mmol/L比(2.45±1.99)mmol/L、(0.64±0.52)g/L比(0.44±0.12)g/L、(20.68±4.66)μmol/L比(15.07±3.45)μmol/L](P〈0.05或〈0.01)。TSH〉10.0mU/L组和TSH4.0-10.0mU/L组TG、TC、LP(a)、Hey、24hUNALB比较差异有统计学意义[(3.88±0.45)mmol/L比(2.12±0.61)mmol/L、(6.88±1.44)mmo]]L比(5.79±0.86)mmol/L、(0.88±0.09)g/L比(0.50±0.10)g/L、(24.13±2.10)μmol/L比(19.54±3.18)μmol/L、(100.10±24.18)mg/24h比(80.21±18.99)mg/24h](P〈0.01或〈0.05);采用Spearman相关分析,TSH〉10.0mU/L组TSH与TG(r=0.681)、TC(r=0.840)、LP(a)(r=0.692)、Hey(r=0.774)、24hUMALB(r=0.722)呈正相关(P〈0.05)。TSH4.0~10.0mU/L组中,Hey增高患者的糖尿病。肾病、糖尿病视网膜病变、糖尿病大血管病变发生率较Hey正常患者明显增加[12.9%(4/31)比7/19、22.6%(7/31)比10/19、16.1%(5/31)比9/19](P〈O.05)。结论2型糖尿病合并亚临床甲状腺功能减退可能存在更明显的血脂异常和胰岛素抵抗,且更易出现糖尿病大血管和微血管并发症,TSH〉10mU/L或TSH4.0-10.0mU/L且Hey异常时,应积极给予小剂量甲状腺激素替代治疗。 Objective To investigate the clinical feature of type 2 diabetes mellitus combined with subclinical hypothyroidism to provide the clinical evidence for treatment. Methods One hundred and twenty-eight type 2 diabetes mellitus patients combined with subclinical hypothyroidism were selected as observation group, 200 type 2 diabetes mellitus patients combined with normal thyroid function were selectedas control group. The clinical indexes such as body mass index (BMI),glycosylated hemoglobin (HbAje), fasting plasma glucose (FPG),2-hour postprandial plasma glucose (2 h PPG), fasting C-peptide (FCP), 2-hour postprandial C-peptide (2 h PCP), triglyceride (TG), total cholesterol (TC), low-density lipoprotein- cholesterol (LDL-C), high density lipoprotein- cholesterol (HDL-C), lipoprotein (a) [LP (a)], homocysteine (Hcy), 24-hour microalbuminuria (24 h UMALB) were compared between two groups. 10.0 mU/L thyroid stimulating hormone (TSH) was used as the cut point and patients in observation group were divided into two groups ( 〉 10.0 mU/L group,4.0 - 10.0 mU/L group),the above indexes were compared between two groups,and the correlation of TSH and clinical indexes was analyzed. In TSH 4.0 - 10.0 mU/L group, the incidence of diabetic nephropathy, diabetic retinopathy, diabetic vascular disease between Hey normal or abnormity was compared. Results The level of BMI, FPG, FCP, TG,TC, LDL-C, LP (a) and Hey between observation group and control group had significant difference [ (27.8 ± 2.8 ) kg/m2 vs. (24.6 ± 3.2 ) kg/m2, ( 8.64 ± 2.79 ) mmol/L vs. ( 6.71 ± 3.65 ) mmol/L, ( 1.99 ±1.24 ) μg/L vs. ( 2.56 ± 1.03 ) μg/L, ( 3.26 ± 0.76 ) mmol/L vs. ( 2.04 ± 0.18 ) mmol/L, ( 6.08 ± 1.74 ) mmol/L vs. (4.95 ± 2.11 ) mmol/L, ( 3.86 ± 2.01) mmol/L ± (2.45 ± 1.99) mmolIL, (0.64 ±0.52) g/L vs. (0.44 ±0.12) g/L,(20.68 ±4.66) μmol/L vs. (15.07 ±3.45) μmol/L](P〈0.05 or 〈0.01). The level ofTG, TC, LP (a), Hey and 24 h UMALB between TSH 〉 10.0 mU/L group and TSH 4.0 - 10.0 mU/L group had significant difference [ (3.88 ± 0.45 ) mmol/L vs. (2.12 ± 0.61 ) mmol/L, (6.88 ± 1.44) mmol/L vs. (5.79 ± 0.86) mmol/L, (0.88 ± 0.09) g/L vs. (0.50 ±0.10) g/L, (24.13 ±2.10) μ mol/L vs. (19.54 ±3.18)μmol/L, (100.10 +24.18) mg/24 h vs. (80.21 ± 18.99) mg/24 hi(P〈0.01 or 〈0.05). In TSH 〉 10.0 mU/L group,TG (r =0.681), TC (r = 0.840), LP(a)(r = 0.692), Hcy (r = 0.774) and 24 h UMALB (r = 0.722) was positively related with TSH by Spearman correlation analysis. In TSH 4.0 - 10.0 mU/L group , the incidence of diabetic nephropathy, diabetic retinopathy and diabetic vascular disease was significantly increased in patients with high Hey [ 12.9%(4/31) vs. 7/19,22.6%(7/31) vs. 10/19,16.1%(5/31) vs. 9/19](P〈 0.05). Conclusions Type 2 diabetes mellitus combined with subclinical hypothyroidism may have more obvious lipid abnormity,more pronounced insulin resistance, and may be more likely to have maerovaseular and microvascular complication. Patients of TSH 〉 10.0 mU/L or TSH 4.0 - 10.0 mU/L with high Hcy should be given a small dose of thyroid hormone replaeement therapy actively.
