摘要 目的探讨慢性阻塞性肺疾病(COPD)合并2型糖尿病(T2DM)老年患者T细胞免疫及Th亚群失衡状况与胰岛素抵抗相关性。方法选取老年COPD稳定期合并T2DM住院患者18例,单纯糖尿病组20例,老年健康对照组20例。探讨COPD合并T2DM患者免疫功能状态及分析免疫失衡状态与胰岛素抵抗的相关性。结果 COPD合并T2DM组、单纯T2DM组与健康对照组比较:CD^(4+)、IL-4、CD^(4+)/CD^(8+)比值下降,CD^(8+)、INF-γ、INF-γ/IL-4比值升高(P<0.05)。COPD合并T2DM组与单纯T2DM组比较:FINS、HOMA-IR升高(P<0.05);CD^(4+)、IL-4、CD^(4+)/CD^(8+)比值下降,CD^(8+)、INF-γ、INF-γ/IL-4比值升高(P<0.05)更为显著(P<0.05)。COPD合并T2DM患者免疫指标及胰岛素抵抗相关性分析提示:HOMA-IR与CD^(8+)、INF-γ/IL-4呈正相关;HOMA-IR与CD^(4+)/CD^(8+)、IL-4呈负相关。结论 COPD合并T2DM可加重机体炎症反应及T淋巴细胞失衡,T淋巴细胞免疫失衡与胰岛素抵抗相关。
