84例变应性鼻炎患儿过敏原皮内试验结果分析

目的 了解新疆地区变应性鼻炎患儿气传过敏原的分布状况,探讨气传变应原分布的地区差异及产生原因,为本地区儿童变应性鼻炎的防治方案提供客观依据.方法 采用阿罗格(NHD)点刺液进行皮肤点刺试验84例变应性鼻炎患儿进行气传变应原测试.结果 84例变应性鼻炎患儿吸入变应原测试总阳性率96.4%(81例),以藜属花粉最高70.2%(59例),蒿属植物次之42.9%(36例),其后依次为杨树27.4%(23例),榆树25.0%(21例),槭树17.8%(15例),柳树11.9%(10例),豚草(巨大豚草、普通豚草)11.9%(10例),粉螨10.7%(9例),尘螨9.5%(8例),交链孢霉8.3%(7例),特异青霉7.1%(6例),白色念珠菌4.8%(4例)等.81例对不同变应原过敏,其中42例(51.9%)患儿对2种或2种以上变应原过敏.点刺试验皮肤反应强度蒿属最明显,强阳性占蒿属过敏病人的50.0%,藜属次之,强阳性占藜属过敏病人的40.7%.结论 藜属和蒿属为新疆地区变应性鼻炎患儿最主要的变应原,在治疗过程中对这类变应性鼻炎患儿可采取有效的避、忌、替、移等措施,明确变应原后对特异性免疫治疗具有重要的指导意义.

The allergenic test in vivo for eighty-four children with allergic rhinitis

Objetive To investigate the geographic distribution of air-borne allergens which caused child rhinitis in Xinjiang,and offer guide for prevention and treatment of the child with allergic rhinitis.Methods Skin prick tests were performed to 84 children with allergic rhinitis by assay of Novo-helisen depot(NHD)fluid.Results The total positive rate of inhaled aHergens among 84 children with allergic rhinitis was 96.4%.The most frequent of allergen Was chenopedium(70.2%).The other frequent allergens were artemisia42.9%(36 cases),poplar 27.4%(23 cases),elm 25%(21 cases),maple 17.8%(15 cases),willow 11.9%(10 cases),ragweed(macrosis,common)11.9%(10 cases),flour mite 10.7%(9 cases),dust-mite 9.5%(8 cases).Eighty-one cases were sensitivity to multi-allergens,and 42 cases(51.9%)were allergic to at least two or more allergens.Skin prick tests showed that half of the children were allergic to artemisia.40.7%children were sensitive to chenopodium.Conclusion Chenopedium and artemisia were the main allergens in children with allergic rhinitis in Xinjiang.Children with allergic rhinifis should avoid contacting these aHergens.
