摘要
目的探讨甲状腺功能减退症(hypothyroidism,PWH)患者经左甲状腺素治疗后对血管内皮功能的影响。方法选取我院2014年1月—2015年8月初治PWH患者80例,均给予左甲状腺素口服治疗。比较治疗前、治疗后6个月血总三碘甲状腺原氨酸(TT_3)、游离三碘甲状腺原氨酸(FT_3)、总甲状腺素(TT_4)、游离甲状腺素(FT_4)、促甲状腺激素(TSH)、抗凝血酶Ⅲ(AT-Ⅲ)活性、C-反应蛋白(CRP)、纤维蛋白原(FIB)、同型半胱氨酸(HCY)、总胆固醇(TC)、高密度脂蛋白胆固醇(HDL-C)、低密度脂蛋白胆固醇(LDL-C)、甘油三酯(TG)及肱动脉血流介导的血管舒张(flow-mediated dilatation,FMD)指数,并进一步行多元线性回归分析各实验室指标对血管内皮功能的影响。结果治疗后6个月血TT_3、FT_3、TT_4、FT_4、AT-Ⅲ活性、HDL-C、FMD指数明显高于治疗前,TSH、CRP、FIB、HCY、TC、LDL-C、TG明显低于治疗前,差异均有统计学意义(P<0.05或P<0.01)。多元线性回归分析结果显示:TT_3、TT_4、FT_4、TSH、CRP、HCY、TC、LDL-C是血管内皮舒张功能的危险影响因子,HDL-C、AT-Ⅲ活性为血管内皮舒张功能的保护因子。结论通过左甲状腺素治疗能改善PWH患者血管内皮舒张功能。
Objective To investigate the effect of Levothyroxine on vascular endothelial function of patients with hy-pothyroidism (DWH). Methods A total of 80 patients with hypothyroidism during January 2014 and Augest 2015 all received Levothyroxine orally. Levels of blood total triiodothyronine ( TT3 ), free triiodothyronine ( FT3 ), total thyroxine (TT4),free thyroxine ( FT4 ), thyroid stimulating hormone ( TSH), plasma antithrombin Ⅲ( AT-Ⅲ) activity and C-reactive protein (CRP), fibrinogen (FIB) and homocysteic acid (HCY), total cholesterol (TC), high density lipoprotein cholesterol (HDL-C) , low density lipoprotein cholesterol (LDL-C), triglyceride (TG) and brachial artery flow-mediated dilatation (FMD) indexes before and after 6 months of treatment were compared. Multiple linear regression analysis was performed to analyze effects of each index on FMD function. Results After 6 months of treatment, TT3 , FT3 , TT4 , FT4 , AT-Ill activity, HDL-C and FMD index levels were significantly higher, while TSH, CRP, FIB, HCY, TC, LDL-C and TG levels were signif- icantly lower than those before treatment (P 〈 0.05 or P 〈 0. 01 ). Multiple linear regression analysis showed that TT3 , TT4 , FT4, TSH, CRP, HCY, TC and LDL-C were risk factors of FMD, while HDL-C and AT-Ⅲ activity were protection factor of FMD. Conclusion Levothyroxine treatment can improve FMD of patients with hypothyroidism.
