摘要 目的通过对谷氨酸脱羧酶抗体(GAD—Ab)的测定,探讨成人隐匿性自身免疫糖尿病(LADA)的临床特征,找出临床筛查线索,从而指导糖尿病的正确分型和治疗。方法选择200例初诊成人2型糖尿病(T2DM)患者检测GAD—Ab,同时结合空腹C肽、餐后两小时C肽、糖化血红蛋白(HbA1C)、总胆固醇(TC)、甘油三酯(TG)结果及性别、年龄分组,比较各组间临床特点。结果(1)GAD—Ab在T2DM的阳性检出率为5.0%(10/200),30—40岁为5.6%,40—49岁为3.2%,50~59岁为11.5%。(2)LADA组与T2DM组在体重指数(BMI)、空腹C肽、餐后两小时C肽方面差异有统计学意义(P〈0.05),而在性别、年龄、血甘油三酯(TG)、胆固醇(TC)水平、糖化血红蛋白(HBA1C)方面相比差异无统计学意义,P≥0.05。结论低体重指数(BMI)、低C肽水平是筛查LADA重要的临床线索,谷氨酸脱羧酶抗体(GAD—Ab)检测可提高诊断LADA的敏感性。
