概括
患有莱什曼病的狗表现出更高的过敏原特异性免疫球蛋白E (IgE) 水平,但这些可能没有临床意义. 兽医应该谨慎地解释莱什曼病狗的过敏测试结果.
科学领域:
- 兽医免疫学 兽医免疫学
- 狗的传染病 狗的传染病
- 过敏学 过敏学
背景情况:
- 患有莱什曼病的狗表现出强烈的,与抗莱什曼病婴儿抗体相关的非保护性幽默反应.
- 狗皮炎 (cAD) 也涉及幽默性免疫反应,特别是过敏原特异性免疫球蛋白E (IgE).
研究的目的:
- 为了比较血清过敏原特异性IgE度在患有莱什曼病的狗和高抗L.婴儿抗体对健康和亚托皮狗.
- 调查莱什曼病与IgE水平升高之间的潜在联系.
主要方法:
- 来自47只莱什曼病 (没有cAD) 和30只亚托皮病狗的血清样本与33只健康的狗进行了比较.
- 使用商业套件进行了对过敏原特异性IgE的定量测量.
- 具有抗交叉反应性碳水化合物决定因子 (CCD) -IgE的狗被排除在分析之外.
主要成果:
- 与健康 (18/28) 和亚托皮性狗 (10/30) 相比,莱什曼症狗 (40/40) 的比例显著更高,至少有一种过敏原的检测结果呈阳性.
- 过敏原特异性IgE水平的中位数在莱什曼病狗中为7.1U/mL,在亚托皮狗中为4.7U/mL,在健康狗中为1.4U/mL.
- 在利什曼病和健康的狗之间发现了显著的差异,但在利什曼病和亚托邦狗之间没有,也没有在亚托邦狗和健康的狗之间.
结论:
- 患有中度至重度莱什曼尼病和高抗L.婴儿抗体的狗产生高血清过敏原特异性IgE.
- 莱什曼病狗的这些高IgE水平可能对阿托皮症没有临床意义.
- 临床医生在诊断为莱什曼尼病的狗中解释血清过敏原测试时应谨慎行事.

Overview
Antibodies, also known as immunoglobulins (Ig), are essential players of the adaptive immune system. These antigen-binding proteins are produced by B cells and make up 20 percent of the total blood plasma by weight. In mammals, antibodies fall into five different classes, which each elicits a different biological response upon antigen binding.

In 1971, Peter Perlman and Eva Engvall developed an Enzyme-linked immunosorbent assay (ELISA or EIA). ELISA differs from western blot in that the assays are conducted in microtiter plates or in vivo rather than on an absorbent membrane.
There are many different types of ELISAs, but they all involve an antibody molecule whose constant region binds an enzyme, leaving the variable region free to bind its specific antigen. Enzyme-substrate reaction allows the antigen to be visualized or...
