[摘要]目的探討亞臨床甲狀腺功能減退(subclinicalhypothyroidism,SCH)與糖尿病視網膜病變(diabeticretinopathy,DR)的相關性。方法選取2019年1月至2022年3月筆者醫院內分泌科收治的2型糖尿病(type2diabetesmellitus,T2DM)患者481例,根據患有DR的情況分為無DR組(n=327)、非嚴重DR組(n=92)和嚴重DR組(n=62)。比較各組臨床資料,Spearman相關分析DR嚴重程度與其他指標的相關性。Logistic回歸分析DR以及嚴重DR的影響因素。結果非嚴重DR組促甲狀腺激素(Thyroidstimulatinghormone,TSH)高于無DR組(P<0.05),游離甲狀腺素(freethyroxine,FT4)低于無DR組(P<0.05)。嚴重DR組收縮壓、舒張壓、血肌酐(serumcreatinine,Scr)均高于無DR組(P<0.05),游離三碘甲狀腺原氨酸(freetriiodothyronine,FT3)、FT4均低于無DR組(P<0.05)。Spearman相關分析顯示,DR嚴重程度與收縮壓、舒張壓、糖尿病病程、低密度脂蛋白膽固醇、Scr、TSH呈正相關(r=0.213、0.142、0.251、0.100、0.159、0.110,P<0.05),與FT3、FT4呈負相關(r=–0.103、–0.133,P<0.05)。Logistic回歸分析顯示,收縮壓、糖尿病病程≥10年、低密度脂蛋白膽固醇、Scr、TSH>4.2mIU/L、FT4是DR的影響因素。收縮壓、Scr、TSH>4.2mIU/L是嚴重DR的影響因素。結論SCH是DR和嚴重DR的危險因素。

2型糖尿病(type2diabetesmellitus,T2DM)的患病率呈逐年上升的趨勢,目前已成為全球重大的公共健康問題之一。糖尿病視網膜病變(diabeticretinopathy,DR)是糖尿病(diabetesmellitus,DM)常見的并發癥,DR的患病率約占糖尿病人群的30%,是成人視力喪失的主要原因[1]。
T2DM與亞臨床甲狀腺功能減退(subclinicalhypothyroidism,SCH)(以下簡稱甲減)發生的風險增加有關[2]。SCH是代謝綜合征、動脈粥樣硬化和心血管事件的危險因素[3-5]。有研究表明T2DM合并SCH發生DR的風險是不合并SCH的1.144倍,但也有研究認為合并SCH不會增加DR風險,有研究表明高促甲狀腺激素(thyroidstimulatinghormone,TSH)水平不是DR發生的獨立危險因素[6-8]。因此,目前SCH與DR關系的研究結論存在矛盾,且較少研究去探討SCH和DR的關系。……
