Many people with eczema have antibodies in their blood to allergens in the environment such as house dust mite; they are then classified as being atopic.
In residential settings, hygrometers are used to aid humidity control (too low humidity damages human skin and body, while too high humidity favours growth of mildew and dust mite).
Allergen immunotherapy is available for selected patients with house dust mite allergy but typically injections need to be given regularly for three to five years.
In cases where the allergens are seasonal the clinical signs of irritation are similarly seasonal, but many dogs with house dust mite allergy have perennial disease.
When a house dust mite allergen was introduced, which is a common human allergen, both airway remodelling and allergic airway inflammation were more significantly enhanced.
