感染症建立在具有IgE产生系统的宿主和具有抗原性的寄生物两方面因素的相互关系基础上.寄生性蠕虫(线虫、吸虫、绦虫)、真菌能产生大量IgE,而寄生性原虫、细菌、病毒等一般不能产生IgE.这里仅介绍寄生虫感染症和IgE的关系.蠕虫感染感染蠕虫的宿主血中IgE值升高及嗜酸细胞增多是其特征.通常呈现高IgE血症和嗜酸白细胞增多症的病例,当否定是花粉症和特应性皮炎等Ⅰ型变态反应疾病时,可疑诊为蠕虫感染.
Infections are based on the interrelationship between a host that has an IgE-producing system and an antigenic parasite: parasitic worms (nematodes, trematodes, tapeworms), which produce large amounts of IgE, while parasitic protozoa, bacteria, Viruses and the like generally can not produce IgE here is only introduced the relationship between parasitic infections and IgE worm infection infected host worm blood IgE values and eosinophilia is characterized by usually hyperosmolarity and eosinophils Cases of polyps disease, when the negative is allergic diseases such as hay fever and atopic dermatitis type Ⅰ, suspicious diagnosis of worm infection.
