The American Academy of Pediatrics (AAP) has issued a new report on environmental control of allergies in the treatment of asthma. Most children with asthma also have allergies to indoor or outdoor allergens or both. Control of exposure to allergens has long been a recommended part of allergy and asthma treatment, but it is still underused. Even when diagnosed, control of indoor allergen exposure can be difficult and expensive and is usually something that is not covered by insurance. If renting, landlords may be reluctant to control some sources and legal action is sometimes required.
The report notes that control of exposure to allergens can be as effective as medication in the treatment of asthma.
The guidelines recommend:
- Obtaining an environmental exposure history for both indoor and outdoor allergens. The most common indoor allergens are dust mite, cockroach, molds, pets, mice, rats. Also environmental pollutants such as smoke and use of gas stoves and appliances.
- Blood or skin testing for allergies may be performed.
- For indoor allergens, there are specific ways to target and reduce each allergen. Sources can be reduced or eliminated, HEPA filters can be used, or pillow and mattress covers and air purifiers can reduce exposure.
