The house dust mite (sometimes referred to byas HDM) is a guest in habitation. Dust feed on organic detritus such as flakes of shed human skin and flourish in the stable environment of dwellings. House dust mites are a common cause of and allergic symptoms worldwide. The mite's gut contains potent digestive enzymes (notably ) that persist in their feces and are major inducers of allergic reactions such as . The mite's exoskeleton can also contribute to allergic reactions. The European house dust mite (Dermatophagoides pteronyssinus) and the American house dust mite (Dermatophagoides farinae) are two different species, but are not necessarily confined to Europe or North America; a third species Euroglyphus maynei also occurs widely
Asthma and allergies
Allergens produced by house dust mites are among the most common triggers of asthma. There are at least 15 mite allergens which are subdivided into groups. Group 1 and 2 allergens are the most problematic. Group 1 consists of proteins with a catalytic activity, for example Der p 1 (Dermatophagoides pteronyssinus group 1) allergen is a cysteine protease, as is its American counterpart Der f 1 (Dermatophagoides farinae group 1). Group 2 are proteins important for the mite. Proteins from the other groups affect only few patients. Studies have shown the mean attributable fraction of adult asthma due to atopic sensitization was 30% and 18% for sensitization to dust mites. Taken into consideration this could mean as many as 1.2 billion people could have some form of chronic sensitization to dust mites.
How to prevent the dust mite allergy:
Step 1 Encase your bed
Encasing your bed is the single most important step in controlling your exposure to indoor allergens at home. You spend up to 8 hours a night in your bed, so the bed is the best and most physician-recommended place to start. Mattresses, pillows and comforters provide a thriving environment for dust mites. There are up to 1 million dust mites living in any bed, waiting to feast off your dead skin cells, and causing you allergy symptoms with the fecal matter they leave behind. ICK!
