Mite allergens
Richard F. Lockey, Dennis K. Ledford in Allergens and Allergen Immunotherapy, 2020
Another important group of mites, referred to as “storage mites,” comprises members of the Acaridae and Glycyphagidae families that live in stored food and grains. All mite species present in the home environment capable of inducing IgE-mediated sensitization are called “domestic mites” [2]. Approximately 150 storage mite species are known [3], of which perhaps 20 can be considered important from an economic and sanitary perspective. The most studied species are B. tropicalis, due to its abundance in tropical and subtropical regions of the world [4], and L. destructor, because of its frequent presence in barns. Storage mite species can be present in kitchen floor dust, cupboards, and pantries. They can be an important plague with economic consequences and cause occupational respiratory allergies in farmers and other occupationally exposed individuals. The most important genera are Blomia (family Echimyopodidae), Lepidoglyphus and Glycyphagus (family Glycyphagidae), Acarus, Tyrophagus and Aleuroglyphus (family Acaridae), Suidasia (family Suidasidae), Chortoglyphus (family Chortoglyphidae), and Cheyletus (family Cheyletidae). Since B. tropicalis is present in large quantities in house dust in tropical and subtropical regions, it could also be considered an HDM species.

Another important group of mites, referred to as “storage mites,” comprises mainly members of the Acaridae and Glycyphagidae families that live in stored food and grains. All mite species present in the home environment, which are capable of inducing IgE-mediated sensitization, are currently called “domestic mites” [2]. Approximately, 150 storage mite species are known [3] and approximately 20 can be considered important from an economic and sanitary perspective. The most studied species are Blomia tropicalis, due to its abundance in tropical and subtropical regions of the world [4], and Lepidoglyphus destructor, because of its frequent presence in barns. Storage mite species can be present in kitchen floor dust, cupboards, and pantries. In humid homes, storage mites can also be found in mattress dust. They can be an important plague with economic consequences and cause occupational respiratory allergies in farmers and other occupationally exposed individuals. The most important genera are Blomia (Family Echimyopodidae); Lepidoglyphus and Glycyphagus (Family Glycyphagidae); Acarus, Tyrophagus, and Aleuroglyphus (Family Acaridae); Suidasia (Family Suidasidae); Chortoglyphus (Family Chortoglyphidae); and Cheyletus (Family Cheyletidae).
Delayed Immunomodulatory Effect of Cow Milk–Free Diet in Ménière's Disease
Published in Journal of the American College of Nutrition, 2018

The patient had suffered from intermittent and seasonal allergic rhino-conjunctivitis since 1985. In 2012, skin tests were carried out in accordance with the recommendations of the European Academy of Allergology and Clinical Immunology (12): prick tests were positive for house dust mite, grass and birch pollen, and cow milk proteins, whereas they were negative for the other most common inhalant and fresh food allergens and to gliadin, even after 24 hours. Specific Immunoglobulin E (IgE) to Dermatophagoides mix, grass pollen, Betulaceae, and milk were in class 3–4 (RAST-CAP System EIA method, Pharmacia, Uppsala, Sweden). The common autoantibodies profile was negative. A possible role of allergy in the symptoms of MD was suspected and, in October 2012, the patient initially tried a deprivation diet, eliminating foods that contain cow milk and its derivatives. The patient was allowed to consume only soy and rice milk; other milk products, such as sheep or goat milk/cheese were avoided, but symptoms persisted for the following 6 months. No other pharmacological treatment was administered during and after the dietary period. In March 2013, the patient began 2 concurrent subcutaneous immunotherapies (SARM Allergeni, Guidonia–Rome, Italy), one for mites (40% Dermatophagoides, 30% Gliciphagidae, and 30% Acaridae) and another one for grass pollen (80% mix: Dactylis, Festuca, Lolium, Phleum, Poa, Agrostis, Antoxanthum and 20% Cynodon D).
