What is Dermatophagoides pteronyssinus IgE? ›

Dermatophagoides pteronyssinus (d1) IgE - This allergen-specific IgE antibody test quantifies an individual's IgE response to Dermatophagoides pteronyssinus, a species of house dust mites that can cause atopic reactivity and allergic disease affecting the eyes, airways, skin, and occasionally the circulation [1].

Dermatophagoides spp. dust mites have highly allergenic exoskeletons, body fragments, and feces, all of which can be easily aerosolized during bed making and pillow fluffing. Allergens from living and dead dust mites frequently cause allergic rhinitis and asthmatic bronchitis in predisposed, atopic persons.

Based on studies of Dermatophagoides pteronyssinus only, weekly washing in hot water is recommended to kill dust mites and remove allergens from clothing and bedding. However, in the United States, washing is most often done in warm or cold water, and other mite species are involved.

Areas around the home that are heavily used, such as beds and upholstered furniture, will have much higher mite populations than the rest of the house. The most common type of dust mite found in Australian homes is Dermatophagoides pteronyssinus, which tends to prefer coastal rather than inland areas.

But people who have dust mite allergies may become allergic to foods like shellfish and mollusks such as mussels, crabs, lobsters, shrimps or snails. Severe symptoms may increase the risk of developing other medical conditions such as sinusitis (inflammation of the sinuses).

Treatment with ACTAIR has been shown to induce a systemic antibody response towards house dust mite allergens, with an increase in specific IgG4 antibodies in some patients. These immunoglobulins may compete with IgE for allergen binding, thereby decreasing allergen capture and presentation.

Prolonged exposure to dust mites can cause chronic inflammation, wheezing and difficulty breathing, all associated with asthma. Dust mites thrive in warm, humid environments.

Overview. Dust mite allergy is an allergic reaction to tiny bugs that commonly live in house dust. Signs of dust mite allergy include those common to hay fever, such as sneezing and runny nose. Many people with dust mite allergy also experience signs of asthma, such as wheezing and difficulty breathing.

Limiting your exposure to dust mites will reduce your symptoms. However, it's nearly impossible to completely get rid of dust mites in your environment. You may also need medicines to control symptoms. Certain over-the-counter and prescription medicines may help reduce dust mite allergy symptoms.

Allergy medications

These drugs relieve itching, sneezing and runny nose. Over-the-counter antihistamine tablets, such as fexofenadine (Allegra Allergy), loratadine (Alavert, Claritin,), cetirizine (Zyrtec) and others, as well as antihistamine syrups for children, are available.

How do you treat Dermatophagoides? ›

Treatment of Dermatophagoides farinae Allergy

This therapy involves gradually introducing the body to the allergen, aiming to develop tolerance and reduce allergic symptoms over time. Sublingual immunotherapy, a key form of this treatment, administers allergens under the tongue in controlled doses.

A blood test for the presence of specific IgE antibodies provides an indication of the immune response to the specific allergen. The allergens selected for the test depend on the age of the patient, the history of exposure to specific allergens, the time of year as well as the clinical manifestations.

IgE is an antibody that your body makes. If you have allergies, you may have more IgE in your blood than normal. Allergies are a common, long-term condition that involves your immune system. Your immune system makes antibodies to fight off viruses, bacteria, and other things that can make you sick.

The term "house dust mites" has been applied to a large number of mites found in association with dust in dwellings. The American house dust mite, Dermatophagoides farinae Hughes, and the European house dust mite, Dermatophagoides pteronyssinus (Trouessart), are discussed here.

Dust mites eat organic matter such as skin cells people have shed, and rather than drinking water, they absorb water from humidity in the atmosphere. Dust also contains the feces and decaying bodies of dust mites, and it's the proteins present in this dust mite "debris" that are the culprit in dust mite allergy.
