Hausstaubmilbenallergie

Abstract

House dust mites can be found all over the world where human beings live independent from the climate. Proteins from the gastrointestinal tract- almost all known as enzymes - are the allergens which induce chronic allergic diseases. The inhalation of small amounts of allergens on a regular base all night leads to a slow beginning of the disease with chronically stuffed nose and an exercise induced asthma which later on persists. House dust mites grow well in a humid climate - this can be in well isolated dwellings or in the tropical climate - and nourish from human skin dander. Scales are found in mattresses, upholstered furniture and carpets. The clinical picture with slowly aggravating complaints leads quite often to a delayed diagnosis, which is accidently done on the occasion of a wider spectrum of allergy skin testing. The beginning of a medical therapy with topical steroids as nasal spray or inhalation leads to a fast relief of the complaints. Although discussed in extensive controversies in the literature - at least in Switzerland with the cold winter and dry climate - the recommendation of house dust mite avoidance measures is given to patients with good clinical results. The frequent ventilation of the dwelling with cold air in winter time cause a lower indoor humidity. Covering encasings on mattresses, pillow, and duvets reduces the possibility of chronic contact with mite allergens as well as the weekly changing the bed linen. Another option of therapy is the specific immunotherapy with extracts of house dust mites showing good results in children and adults. Using recombinant allergens will show a better quality in diagnostic as well as in therapeutic specific immunotherapy.

Efficacy analysis of three-year subcutaneous SQ-standardized specific immunotherapy in house dust mite-allergic children with asthma

“…It is estimated that the annual morbidity and mortality rates have been increasing in recent years worldwide. According to a report by the World Health Organization, >80% of asthma in children results from an allergic reaction in which the house dust mite (HDM) is the major pathogen (1). Inhaled corticosteroids (ICSs) and specific immunotherapy (SIT) are widely used inflammatory treatments for controlling the symptoms of asthma (2).…”

The Prevention of House Dust Mite Allergies in Pediatric Asthma

“…Another option is to place the stuffed animals in a pillowcase or laundry bag and wash them in hot water, preferably at temperatures above 130 • F (54 • C), on a regular basis. Alternatively, they can be placed in a plastic bag and stored in the freezer for 24 h. After either method, one should make sure to thoroughly dry the stuffed animals, either by air-drying them or using a hot dryer [30].…”

Effects of climate and environment on migratory old people with allergic diseases in China: Protocol for a Sanya cohort study

“…Furthermore, UV radiation has been associated with the development of eczema and food allergies [ 8 , 9 ]. Additionally, the tropical and humid environments, indoor dust mites facilitate to breed, and dust mites, which are often the trigger of allergic diseases such as allergic rhinitis and asthma [ 10 , 11 ]. Many studies have confirmed that exposure to PM 10 , PM 2.5 , NO 2 , CO, and O 3 , can deteriorate respiratory diseases [ 12 , 13 ].…”
