摘要 目的通过对血清谷氨酸脱羧酶抗体(GAD-Ab)、酪氨酸磷酸酶样蛋白抗体(IA-2A)和胰岛细胞抗体(ICA)联合检测,探讨其对成人隐匿性自身免疫性糖尿病(LADA)的诊断价值。方法用ELISA法测定157例临床诊断为2型糖尿病患者及49例健康查体者的血清GAD-Ab、IA-2A和ICA,并比较抗体阳性和阴性患者的临床特征。结果临床诊断为2型糖尿病的患者GAD-Ab、IA-2A和ICA的阳性率与对照组比较差异有统计学意义(χ2=8.10,8.51,P<0.01;χ2=4.08,P<0.05),且ICA的阳性率低于GAD-Ab、IA-2A阳性率(χ2=5.78,P<0.05);抗体阳性组患者空腹及餐后2 h血清C肽水平较抗体阴性组明显降低(t=9.606,11.175,P<0.001)。结论胰岛自身抗体联合检测可提高LADA患者的检出率;LADA患者胰岛储备功能较差。
