摘要
目的研究1型糖尿病(T1DM)患儿甲状腺功能状态,并探讨胰岛自身抗体阳性是否可预测自身免疫性甲状腺疾病的发生。方法选取2005年1月-2008年9月在中国医科大学附属盛京医院住院新发且资料完整的71例T1DM患儿,进行2~4 a的随访,对其年龄、性别、家族史及内分泌相关检查结果进行分析。对胰岛自身抗体[谷氨酸脱羧酶抗体(GADA)、胰岛细胞抗体(ICA)、胰岛素自身抗体(IAA)、胰岛素瘤相关蛋白2抗体(IA-2)]及甲状腺自身抗体[甲状腺过氧化物酶抗体(TPOAb)、甲状腺球蛋白抗体(TGAb)]检测结果进行分析。结果胰岛自身抗体的检测阳性率:ICA为12.7%(9/71例),IAA为36.6%(26/71例),GADA为54.9%(39/71例),IA-2为46.5%(33/71例)。甲状腺自身抗体检测阳性率:TPOAb阳性率为11.3%(8/71例),TGAb阳性率为8.5%(6/71例),APOAb、TGAb任一抗体阳性率为12.7%(9/71例)。10岁以上患儿甲状腺抗体阳性率高(P=0.031)。甲状腺抗体阳性患儿更易发生甲状腺功能异常(促甲状腺激素:5.6%vs 0,P<0.05)。GADA阳性组甲状腺功能异常率及抗体的阳性率较GADA阴性组偏高,但无统计学差异(TPOAb:8.5%vs 2.8%,P>0.05;TGAb:5.6%vs 2.8%,P>0.05),ICA、IAA阳性组与阴性组比较差异无统计学意义。IA-2阳性组TSH阳性率与IA-2阴性组比较有统计学差异(促甲状腺激素:5.6%vs 0,P<0.05)。71例患儿经过2~4 a随访,无新发甲状腺疾病。结论 IA-2阳性的T1DM患儿可能更易发生甲状腺功能异常。10岁以上T1DM患儿有必要动态监测甲状腺功能。
Objective To determine the thyroid function of the children with type 1 diabetes mellitus( T1DM), and to evaluate whether the presence of islet autoantibodies may predict the development of autoimmune thyroid diseases. Methods Children ( n = 71 ) with newly diagnosed T1DM at Shengjing Hospital of China Medical University between Jan. 2005 and Sep. 2008 were analyzed,included their age, sex, family history and thyroid function, with the follow - up time of 2 - 4 years. Islet autoantibodies [ glutamic acid decarboxylase autoantibody (GADA) , islet cell antibody(ICA) , insulin autoantibody (IAA) , insulinoma associated protein 2 (IA -2 ) ] and anti-thyroid antibodies [ thy-roid peroxidase antibody (TPOAb) , thyroglobulin antibody(TGAb) ] were tested. Results The positive rate of islet autoantibodies was:ICA 12.7% (9/71 cases) ,IAA 36.6% (26/71 cases) ,GADA 54.9% (39/71 cases) ,IA-2 46.5% (33/71 cases). The positive rate of anti - thyroid antibodies among the children was : TPOAb 11.3 % ( 8/71 cases), TGAb 8.5 % ( 6/71 cases) , either of the anitbodies positivity was 12.7% (9/71 cases). The positive rate of anti-thyroid antibodies was higher in the children above 10 years old (P = 0. 031 ). The patients with positive anti - thyroid antibodies were more likely to develop autoimmune thyroiditis [ thyroid stimulating hormone (TSH) : 5.6% vs. O, P 〈 0.05 1. The patients with GADA positive had a higher prevalence rate of anti - thyroid antibodies than those with GADA negative, however,there was no significant difference between them(TPOAb :8.5 % vs 2.8% ,P 〉 0.05 ;TGAb:5.6% vs 2.8% , P 〉 0.05 ) ;there was no significant difference between the ICA, IAA positive group and the ICA, IAA negative group. There was significant difference in TSH be-tween the positive IA - 2 and negative IA - 2 group ( TSH : 5.6% vs. 0, P 〈 0.05 ). During 2 - 4 years follow - up, no thyroid diseases oc-curred. Conclusions IA - 2 positive patients are at higher risk to develop autoimmune thyroid diseases. It is necessary for patients with TI DM above 10 years old to screen thyroid function.
