【摘要】:研究目的:1.探讨2型糖尿病患者血糖控制水平HbAlc对血清甲状腺激素水平的影响。2.探讨体质指数(BMI)与正常范围血清甲状腺激素水平的相关性。研究方法:1.回顾性分析来我院内分泌科诊治的994例2型糖尿病患者(均符合1999年WHO指南)及体检中心的2279例非糖尿病人群的患甲状腺疾病情况。2.纳入835例无甲状腺疾病的2型糖尿病患者及性别和年龄(±2岁)相匹配的835例非糖尿病者,分为糖尿病组及非糖尿病组,测定肝功能、血脂、空腹血糖、糖化血红蛋白(HbAlc)和甲状腺功能,测量身高、腰围、体重,分别比较两组血清甲状腺激素水平,并进一步采用多元线性回归模型分析HbAlc与甲状腺激素(TSH、FT4、FT3及FT3/FT4)的相关性。3.纳入来我院体检中心的2097例排除甲状腺疾病的体检者。根据BMI的水平分为非肥胖组(BMI24kg/m2)及超重肥胖组(BMI≥24kg/m2)。清晨空腹抽血测肝功能、血脂、空腹血糖、HbAlc和甲状腺功能,量身高,腰围,体重;比较两组人群的甲状腺激素水平。多元线性回归模型分析BMI与血清甲状腺激素之间的相关性。结果:1.994例2型糖尿病患者的甲状腺疾病患病率为13.6%;其中亚临床甲减最常见(11.07%),其次为甲状腺机能减退(1.41%)、亚临床甲亢(0.6%)及甲亢(0.5%);而2279例非糖尿病人群甲状腺疾病的患病率为7.99%,其中亚临床甲减最常见(5.97%),其次为甲状腺机能减退症(1%),亚临床甲亢(0.61%)及甲状腺机能亢进(0.39%)。2.2型糖尿病患者中女性合并甲状腺疾病的患病率较男性显著升高,差异有显著统计学意义(19.7%vs.9.1%,P0.05);且2型糖尿病患者甲减(包含临床甲减及亚临床甲减)的患病率随着年龄及糖尿病病程呈增长趋势(趋势P值均0.05),而甲亢(包含临床甲亢及亚临床甲亢)的患病率随着年龄及病程的增长未呈现上升或下降趋势(趋势P值均0.05)。3.2型糖尿病患者的血清FT3, FT3/FT4及TSH水平与非糖尿病者比较显著降低(4.34±0.81vs.4.51±0.65,0.27±0.05 vs.0.28±0.05,2.26±1.39 vs.2.74±1.63,P值0.05)。4.2型糖尿病患者中二甲双胍组、胰岛素组及胰岛素加二甲双胍组这三组与非二甲双胍口服降糖治疗组相比,血清FT3及FT3/FT4水平均显著降低(FT3:4.29±0.85、4.13±0.74及4.26±0.83vs.4.46±0.76;FT3/FT4:0.26±0.06、0.26±0.05及0.27±0.06vs.0.28±0.05,P值均0.05)。5.2型糖尿病组中非甲状腺疾病综合征(NTIS)患病率随着HbAlc的升高而上升,其中低T3血症、低T4血症及低T3和T4血症的患病率亦随着HbAlc的升高而上升(趋势P值均0.05)。6.2型糖尿病患者HbAlc与血清FT3, FT3/FT4及TSH水平显著负相关(P0.001),而与血清FT4水平显著正相关(P0.05)。校正年龄、性别、BMI、腰围、ALT、AST、GGT及TSH后,HbAlc与血清FT3, FT3/FT4仍显著负相关性(P0.001),与血清FT4仍显著正相关性(P0.05)。7.超重肥胖组血清FT3水平及FT3/FT4较非肥胖组明显升高(P0.05),两组比较血清FT4和TSH无显著性差异(P0.05)。8.多元线性回归模型校正年龄、性别、ALT、GGT、TG、LDL、HDL、FPG、 SBP及DBP因素后,非肥胖组人群BMI与血清甲状腺激素FT3、FT3/FT4、TSH及FT4无相关性(β=0.001、0.002、0.047及-0.095,P均0.05)。超重肥胖组人群的BMI与FT3(β=0.054,P0.001)及FT3/FT4 (β= 0.011, P0.001)显著正相关,而与TSH及FT4无相关性(p=0.009及-0.02,P均0.05)。结论:1.2型糖尿病患者长期血糖控制不佳可能会导致非甲状腺疾病综合征,HbAlc与血清FT3及FT3/FT4显著负相关。2.超重和肥胖可引起血清甲状腺激素水平的改变,BMI与血清FT3水平及FT3/FT4显著正相关。
[Abstract]:Objective : To investigate the effect of HbAlc on serum thyroid hormone levels in patients with type 2 diabetes mellitus .
The correlation between BMI and serum thyroid hormones was analyzed by multiple linear regression models . Results : 1.994 patients with type 2 diabetes mellitus had thyroid disease prevalence of 13.6 % ;
Among them subclinical hypothyroidism was the most common ( 11.07 % ) , followed by hypothyroidism ( 1.41 % ) , subclinical hyperthyroidism ( 0.6 % ) and hyperthyroidism ( 0.5 % ) ;
The prevalence of thyroid diseases in 2279 non - diabetic patients was 7.99 % , among which subclinical hypothyroidism was the most common ( 5.97 % ) , followed by hypothyroidism ( 1 % ) , subclinical hyperthyroidism ( 0.61 % ) and hyperthyroidism ( 0.39 % ) .
The prevalence of hypothyroidism ( including clinical hypothyroidism and subclinical hypothyroidism ) increased with age and duration of diabetes ( P < 0.05 ) . The levels of serum FT3 , FT3 / FT4 and TSH in patients with type 2 diabetes mellitus were significantly lower ( 4.34 卤 0.81 vs . 4.51 卤 0.65 , 0.27 卤 0 . 05 vs . 2.74 卤 1 . 63 , P < 0.05 ) .
The prevalence of serum FT3 , FT3 / FT4 , FT3 / FT4 , FT3 / FT4 , FT3 / FT4 , FT3 / FT4 , FT3 / FT4 , FT3 / FT4 , FT3 / FT4 and FT3 / FT4 were significantly correlated ( P0.05 ) . Conclusion : Long - term glucose control in patients with type 1 diabetes may lead to non - thyroid disease syndrome , and HbAlc is negatively correlated with serum FT3 and FT3 / FT4 . Overweight and obesity may cause changes in serum thyroid hormone levels , and BMI is significantly correlated with serum FT3 levels and FT3 / FT4 .
