“…For the uniform rooms, children changed into dedicated school clothes when arriving at school each day. A fourfold to sixfold decrease in airborne cat allergen was achieved in classrooms with school-provided clothing or a pet ownership ban compared with control rooms [30].…”

“…Cat and dog allergen are nearly ubiquitous in indoor spaces, and many studies have detected their presence in places not containing or permitting pets, particularly schools and daycare centers [3,[28][29][30]. Pet allergen is mainly carried into classrooms on the garments of pet owners, and the amount of cat allergen in a school has been shown to be proportional to the number of cat owners in class [30].…”

“…Pet allergen is mainly carried into classrooms on the garments of pet owners, and the amount of cat allergen in a school has been shown to be proportional to the number of cat owners in class [30]. "Second-hand" cat allergen exposure has been suggested to be an important contributor to allergic sensitization and atopic disease among non-pet owners [31,32].…”

Children spend a considerable portion of their time indoors. Therefore, homes and schools are an important source of allergen exposure. Chronic exposure to the major indoor allergens can lead to allergic sensitization and provoke allergic symptoms in children. Environmental assessment is crucial for the identification and quantification of such allergens in indoor spaces. Reduction of allergen exposure below sensitization and symptom thresholds is possible with various remediation techniques. This article reviews and discusses evidence for the assessment and remediation of indoor allergens commonly found in homes and schools. A literature review was performed using the PubMed database for English-language articles published between January 1, 1980, and February 2009. Additional information was obtained from a review of recent textbooks and one professional society's webpage.

“…We found a consistently stronger inverse association between remission and allergic sensitization to furred animals compared with pollen. Furred animal allergens are potent and also present during all seasons; these allergens may also travel to school and other indoor environments on the clothes of pet owners and horseback riders, 35 which might explain the larger impact.…”

BACKGROUND AND OBJECTIVE: To date, a limited number of population-based studies have prospectively evaluated the remission of childhood asthma. This work was intended to study the remission and persistence of childhood asthma and related factors. METHODS: In 1996, a questionnaire was distributed to the parents of all children aged 7 to 8 years in 3 municipalities in northern Sweden, and 3430 (97%) participated. After a validation study, 248 children were identified as having asthma; these children were reassessed annually until age 19 years when 205 (83%) remained. During the follow-up period lung function, bronchial challenge testing, and skin prick tests were performed. Remission was defined as no use of asthma medication and no wheeze during the past 12 months as reported at endpoint and in the 2 annual surveys preceding endpoint (ie, for ≥3 years). RESULTS: At age 19 years, 21% were in remission, 38% had periodic asthma, and 41% persistent asthma. Remission was more common among boys. Sensitization to furred animals and a more severe asthma (asthma score ≥2) at age 7 to 8 years were both inversely associated with remission, odds ratio 0.14 (95% confidence interval 0.04–0.55) and 0.19 (0.07–0.54), respectively. Among children with these 2 characteristics, 82% had persistent asthma during adolescence. Asthma heredity, damp housing, rural living, and smoking were not associated with remission. CONCLUSIONS: The probability of remission of childhood asthma from age 7- to 8-years to age 19 years was largely determined by sensitization status, particularly sensitization to animals, asthma severity, and female gender, factors all inversely related to remission.

“…For instance, cat allergens can still be measured in classrooms from which all children and Review staff with domestic cat exposure have been permanently excluded [81]. There is consensus from all the reviews of prognosis that on average the health benefits from complete removal from exposure are better than those where exposure is reduced [2,5, 10,12].…”

The study of occupational asthma (OA) provides insights into asthma in general, as the cause is known. The relationships between the cause and response can be measured and modifying factors can be identified and their influence quantified. Developing OA has much more serious consequences for the patient than new onset asthma unrelated to work exposures, as the patient's livelihood is nearly always affected. Many healthcare professionals are more ready to accept and act on asthmatic symptoms when they are unrelated to work than when work may be the cause; antagonism can also occur in the workplace. This article reviews some of the areas where development and controversy enrich the study of OA. It makes no attempt to be comprehensive.
