AIM
Indoor allergens exposure is a risk factor for respiratory symptoms in sensitised children. There is limited data on indoor allergen exposures in New Zealand schools.
METHODS
Vacuumed floor dust samples were collected from 136 classrooms in 12 primary schools and analysed for allergens from the house dust mite Dermatophagoides pteronyssinus (Der p 1), cat dander (Fel d 1), cockroach (Bla g 2), cow dander (Bos d 2), horse dander (Equ c 4) and peanut (Ara h 2) by ELISA.
RESULTS
House dust mite, cat, cockroach, cow and horse allergens were detected in 96.4%, 100%, 2.2%, 27.0% and 59.9% respectively in the classrooms dust samples. Thirty-one (22.6%) classrooms had Fel d 1 levels of >8.0µg/g while none had Der p 1 levels of >10.0µg/g. Only one classroom had detectable levels of peanut allergen.
CONCLUSIONS
House dust mite allergen levels were low in New Zealand classrooms while about a quarter of classrooms had cat allergen levels that may be associated with respiratory symptoms.
目的
接触室内过敏原是致敏儿童出现呼吸道症状的一个风险因素。关于新西兰学校室内过敏原接触情况的数据有限。
方法
从12所小学的136间教室收集了用吸尘器吸起的地板灰尘样本，并通过酶联免疫吸附测定法分析其中来自屋尘螨（粉尘螨，Der p 1）、猫皮屑（Fel d 1）、蟑螂（Bla g 2）、牛皮屑（Bos d 2）、马皮屑（Equ c 4）和花生（Ara h 2）的过敏原。
结果
在教室灰尘样本中，分别检测到屋尘螨、猫、蟑螂、牛和马的过敏原的比例为96.4%、100%、2.2%、27.0%和59.9%。31间（22.6%）教室的Fel d 1水平>8.0微克/克，而没有一间教室的Der p 1水平>10.0微克/克。只有一间教室检测到可检测水平的花生过敏原。
结论
新西兰教室中的屋尘螨过敏原水平较低，而约四分之一的教室的猫过敏原水平可能与呼吸道症状有关。
