摘要 目的探讨糖尿病自身抗体与胰岛细胞功能的关系。方法对60例健康者(正常组)和120例初诊为糖尿病的患者(糖尿病组)测定空腹及75 g馒头餐后2 h静脉血浆葡萄糖水平、胰岛素水平、C肽水平,并计算胰岛素敏感指数(ISI),同时测定糖尿病组血清谷氨酸脱羧酶抗体(GAD-Ab)、胰岛素自身抗体(IAA)和胰岛细胞抗体(ICA)水平。观察糖尿病组自身抗体的阳性率和自身抗体与胰岛细胞功能关系。结果糖尿病组GAD-Ab、IAA、ICA阳性率分别为38%(45/120),7%(8/120),6%(7/120),与正常组比较均有显著性差异;糖尿病组胰岛素、C肽比正常组分泌增多,ISI降低;3种抗体全阳性、GAD-Ab阳性、IAA阳性、ICA阳性组的空腹胰岛素、C肽水平均低于全阴性组。结论在初诊的糖尿病患者中,自身抗体阳性预示其胰岛细胞功能受损。
