Abstract
背景:第二型糖尿病(T2DM)患者罹患冠狀動脈疾病(CAD)風險升高,與慢性發炎及氧化壓力密切相關。4-羥基-2-壬烯醛(HNE)為脂質過氧化產物,能修飾蛋白質並誘發免疫反應,加劇動脈粥樣硬化。本研究探討T2DM合併CAD患者血漿中針對HNE修飾之載脂蛋白B-100(ApoB-100)與纖維蛋白原α鏈(FGA)胜肽片段的IgG與IgM自體抗體表現,並評估其與CAD的關聯性。
方法:本研究收集66例T2DM、64例T2DM/CAD≥70% 及65例CAD≥70% 患者的血漿樣本,利用ELISA測定HNE修飾之ApoB-100與FGA特定位點胜肽的IgG與IgM自體抗體表現量。並採用免疫沉澱法及Western blot驗證HNE修飾蛋白的存在。進一步進行相關分析與邏輯回歸評估其與CAD風險及生化特徵之關聯。
結果:結果顯示,T2DM/CAD≥70% 患者的HNE-protein adducts與HNE修飾的ApoB-1001146-1163與FGA427-443IgG自體抗體表現量顯著高於T2DM患者,在邏輯回歸中IgG自體抗體表現量與CAD風險呈正相關。此外,IgG anti-FGA427−443HNE與三酸甘油脂呈顯著正相關,進一步支持其為潛在的風險標誌。
討論:本研究結果顯示,針對HNE修飾ApoB-100與FGA的IgG自體抗體可能為T2DM發展為CAD的危險因子。此外,藥物治療可能影響自體抗體表現,應在後續研究中進一步評估其影響,以更準確解釋其臨床意義,未來可進一步探討其在臨床診斷與風險評估的應用價值。
