发作性过敏性鼻炎属Ⅰ型变应性疾病,其临床表现与血管舒缩性鼻炎相似。但后者无致敏原,可根据皮试、鼻激发试验及放射免疫测定等方法予以鉴别。由内原性细菌引起的过敏性鼻炎属Ⅳ型变应性疾病,因缺乏典型症状,诊断比较困难。鼻分泌物涂片及末梢血液中找到大量嗜酸细胞者,对本病诊断有一定价值,少量者无诊断意义。本病治疗,采用拟交感药物如可的松一类,常可奏效。鼻内长期使用,并不损害局部免疫功能,也不致出现其他器官或全身性副作用。滴鼻比鼻粘膜注射要好。血管收缩剂有时会诱发本病甚至加重病情。急性期可在全身及局部选用抗组织胺药治疗以缓解症状。季节性发作者经以上治疗无效时,可采用长效可
Allergic rhinitis is a type Ⅰ allergic disease, its clinical manifestations and vasomotor rhinitis similar. However, the latter has no allergen and can be identified according to the skin test, nasal challenge test and radioimmunoassay. Allergic rhinitis caused by endogenous bacteria is a type IV allergic disease, due to the lack of typical symptoms, the diagnosis is more difficult. Nasal secretions smear and peripheral blood to find a large number of eosinophils, the diagnosis of the disease has a certain value, a small amount of no diagnostic significance. The disease treatment, the use of sympathomimetic drugs such as cortisone, often can be effective. Long-term use within the nose does not impair local immune function nor does it cause other organ or systemic side effects. Nasal drip better than nasal mucosa. Vasoconstrictors sometimes cause the disease even worse. Acute phase in systemic and local use of antihistamine treatment to alleviate the symptoms. Seasonal attack by the above treatment is invalid, you can use long-term can be
