Dust mite allergy is an allergic response to dust mite allergens that are often found in home dust. It is sometimes referred to as home dust allergies. It is a hypersensitivity and allergic reaction to dust mite droppings. The droppings are an indoor aeroallergen that causes an allergic response when inhaled. The prevalence of atopic illnesses such as allergic rhinitis and asthma, with home dust mites as the allergen, is on the rise. Around 1920, house dust allergy was discovered as an allergen. Dermatophagoides Pteronyssinus (DP) was discovered as the causal allergen causing home dust allergies in 1967. In 1980, the cysteine protease Dermatophagoides pteronyssinus allergen I or DP 1 was discovered, followed by DP 2 and related Dermatophagoides farinae 1 and Dermatophagoides farinae 2. The House Dust Mite (HDM or DM) is the most common source of indoor allergies. Allergic rhino-conjunctivitis, allergic asthma, and atopic eczema are some of the allergic disorders linked to HDM. The best treatment strategy for allergic rhinitis is to avoid allergens initially, followed by medication and Allergen Immunotherapy (AIT). Antihistamines, leukotriene receptor antagonists, and inhaled or Intranasal Corticosteroids (ICS) are the right medication. All of these therapies are effective and safe, but they have not been shown to affect the course of HDM-related allergy disorders.
