CCLM:一种用于测定类固醇21-羟化酶自身抗体的新型ELISA

2018-06-01 MedSci MedSci原创

在本研究的化验样品中,自抗体在涂在厚板21-羟基和液相21-OH-biotin之间形成了一个桥接。研究人员通过添加过氧化物酶和显色过氧化物酶底物,以检测结合的21-OH-biotin。 结果显示,在100例自身免疫性Addison病患者的样本中,86例(86%)为21-OH Ab ELISA阳性,而在125i标记为21-OH的免疫沉淀试验中,84例(84%)为阳性。928例健康成人献血者中有6例

结果显示,在100例自身免疫Addison病患者的样本中,86(86%)21-OH Ab ELISA阳性,而在125i标记为21-OH免疫沉淀试验中,84(84%)为阳性。928例健康成人献血者中有6(0.6%)1(2.0%)1糖尿病(T1DM)的成人患者为ELISA阳性。来自成人Graves病的样本,经ELISA检测GD (n= 50);腹腔疾病(n= 29)、系统性红斑狼疮(n=9)、类风湿关节炎(n=20) 没有呈现阳性。然而,2/51 (3.9%)GD患儿、3/69 (4.3%)Hashimoto甲状腺炎患儿和3/119(2.5%)单纯T1DM或自身免疫性甲状腺疾病患儿ELISA为阳性。

这种新的检测方法对筛查已知有增加临床自身免疫性Addison病风险的患者,特别是HTGD/T1DM的患儿是有用的。
