摘要: 目的了解北京地区变应性鼻炎(AR)和/或过敏性哮喘患者蟑螂致敏特点,为蟑螂致敏患者的防治提供依据。方法回顾性分析2017年1月—2019年12月就诊于北京世纪坛医院变态反应科门诊的AR和/或哮喘患者,采用蟑螂过敏原试剂进行皮肤点刺试验(SPT),比较不同年龄和疾病患者蟑螂致敏情况,观察蟑螂致敏的人群分布特征。采用SAS 9.4软件进行统计学分析。结果纳入9915例患者,蟑螂SPT总阳性率达24.79%(2458/9915),其中15~19岁年龄组阳性率最高(31.65%),0~14岁的患儿SPT阳性率随着年龄的增长逐渐增加,>20岁的患者随着年龄的增长SPT阳性率基本持平。AR患者蟑螂SPT阳性率24.83%(2355/9484),过敏性哮喘患者蟑螂SPT阳性率26.38%(410/1554),AR伴哮喘患者蟑螂SPT阳性率27.34%(307/1123); 单一蟑螂SPT阳性者占9.64%(237/2458),蟑螂合并其他室内吸入性过敏原SPT阳性者占90.36%(2221/2458),合并粉尘螨、屋尘螨、尘土、猫毛和狗毛的SPT阳性率分别为74.25%(1825/2458)、66.27%(1629/2458)、58.99%(1450/2458)、43.08%(1059/2458)和40.85%(1004/2458)。在AR、哮喘、AR伴哮喘3种疾病中,成年组蟑螂SPT阳性率均高于未成年组,其中AR组有统计学差异(25.81% vs.19.07%,P < 0.001)。未成年组中,AR伴哮喘患儿的SPT阳性率高于AR和哮喘。结论北京地区AR和/或过敏性哮喘患者蟑螂致敏性较高,多合并多重吸入过敏原致敏,成人致敏程度高于未成年人。Abstract: ObjectiveTo investigate the sensitization characteristics of cockroach in patients with allergic rhinitis(AR) and/or allergic asthma in Beijing area, and to provide basis for the prevention and treatment of cockroach sensitized population.MethodsClinical data of patients with allergic rhinitis and/or asthma from January 2017 to December 2019 treated in the outpatient Department of Allergy of Beijing Shijitan Hospital were retrospectively analyzed.Skin prick test (SPT) was performed with cockroach allergen reagents. The cockroach sensitization of patients with different ages and diseases was compared, and the population distribution characteristics of cockroach sensitization were observed.Statistical analysis was performed using SAS 9.4 software.ResultsA total of 9915 patients were enrolled in the end.The total positive rate of cockroach SPT was 24.79%(2458/9915), with the highest positive rate (31.65%) in 15-19 years old group. The positive rate of SPT increased with age in patients less than 14 years old, while the positive rate of SPT was basically flat with age in patients more than 20 years old.The positive rate of cockroach SPT was 24.83% (2355/9484) in allergic rhinitis patients, 26.38% (410/1554) in allergic asthma patients, and 27.34% (307/1123) in allergic rhinitis combined with asthma patients. Single cockroach SPT positive accounted for 9.64% (237/2458), cockroach with other indoor inhalation allergens SPT positive accounted for 90.36% (2221/2458). The positive SPT rates for combined Der f, Der p, house dust, cat dander, and dog dander were 74.25% (1825/2458), 66.27% (1629/2458), 58.99% (1450/2458), 43.08% (1059/2458), and 40.85% (1004/2458), respectively.In allergic rhinitis, asthma, and allergic rhinitis combined with asthma, the cockroach SPT positive rate was higher in the adult group than that in juvenile group, and the difference of positive rate in allergic rhinitis group was statistically significant(25.81% vs 19.07%, P < 0.001).In the juvenile group, the positive rate of SPT in AR combined with asthma was higher than that in AR and that in asthma.ConclusionCockroach allergy in patients with AR and/or allergic asthma in Beijing is relatively high, most of them are sensitized by multiple inhalation allergens, and the sensitization degree of adults is higher than that of juvenile.
