目的　研究变应原检测在咳嗽变异性哮喘诊断中的价值。方法　使用变应原和变应原稀析液对 89例咳嗽变异性哮喘患儿进行皮内注射 ,并进行血清荧光酶免疫检测。结果　 89例中 ,变应原皮试阳性占 6 7 4 2 % ,螨和野苋菜花粉是该组的主要变应原 ;随着年龄增大 ,变应原阳性检出率增高 ;过敏高危因素咳嗽变异性哮喘组 ,Phadiatop检测阳性检出率占 96 6 6 % ,无过敏高危因素咳嗽变异性哮喘组均为阴性。 结论　对咳嗽变异性哮喘患儿进行过敏原检测 ,可以找出诱发原因 ,为预防和免疫治疗提供依据。 Objective To investigate the value of allergen testing in the diagnosis of cough variant asthma. Methods Eighty-nine children with cough variant asthma were injected intradermally with allergen and allergen solution, and serum fluorescent enzyme immunoassay was performed. Results In 89 cases, the skin test positive allergen accounted for 67.42%, mites and amaranth pollen is the main allergen; with age, allergen positive detection rate increased; risk factors for allergic cough In the variant asthma group, the positive detection rate of Phadiatop test was 96.66%, and no allergic high risk factor was found in the cough variant asthma group. Conclusion Allergen detection in children with cough variant asthma can identify the cause of induction and provide the basis for prevention and immunotherapy.
