Since celiac disease screening by traditional IgA anti-endomysial antibody test is limited by high costs of monkey esophagus commercial kits as well as by rising ethical problems related to the endangered species, the identification of an inexpensive and commonly available substrate for this antibody determination is urgently required. To achieve this goal, we compared the prevalence of IgA anti-endomysial antibodies detected on monkey esophagus with that on human umbilical cord. Fifty-seven (95%) of 60 untreated adult celiacs were positive for these antibodies on monkey esophagus as well as on human umbilical cord. IgA anti-endomysial antibodies, detected on both tissues, were negative in all 200 disease and healthy controls tested, displaying a 100% specificity for gluten-sensitive enteropathy. These data suggest that human umbilical cord can replace monkey esophagus for IgA anti-endomysial antibodies test. Human umbilical cord allows unlimited testing for celiac disease screening on wide series of high-risk subjects, permitting identification of greater numbers of asymptomatic celiac patients with a remarkable saving of money and bypassing the ethical problems related to killing monkeys.
由于通过传统的IgA抗肌内膜抗体检测进行乳糜泻筛查受到猴食管商业试剂盒高成本以及与濒危物种相关的伦理问题不断增加的限制,因此迫切需要找到一种用于该抗体测定的廉价且普遍可用的底物。为了实现这一目标,我们比较了在猴食管和人脐带上检测到的IgA抗肌内膜抗体的阳性率。60名未经治疗的成年乳糜泻患者中有57名(95%)在猴食管和人脐带上的这些抗体检测呈阳性。在两种组织上检测到的IgA抗肌内膜抗体在所有200名疾病和健康对照中均为阴性,对麸质敏感肠病显示出100%的特异性。这些数据表明,人脐带可以替代猴食管用于IgA抗肌内膜抗体检测。人脐带允许对大量高危受试者进行无限制的乳糜泻筛查检测,能够识别出更多无症状的乳糜泻患者,显著节省资金,并避免了与捕杀猴子相关的伦理问题。
