Dust Mite Allergy

by Carol Gomes


Dust mite allergy is a result of an adverse reaction, developed towards dust mites. Dust mites are relatives of spiders and are microscopic organisms. They are not visible to the naked eye. They flourish in humid and warm environments and approximately a few million of them are inhabitants of dust-invaded furnishings, clothes and bedding. Inhalation of the decay remnant instigates an allergic reaction. Residues of the decay of the mites or their feces are contagious and results in sneezing, running nose or allergic rhinitis, itchy, watery eyes and breathlessness.

Minimizing dust mite at the home level is the initial step for intervention. Sensitization is the method by which there is an identity crisis, faced by the immune system. It mistakes the residue for an invader an attacks the same by producing immunoglobulin E, an antibody. These antibodies stimulate the synthesis of histamine, an inflammatory chemical that results in the inflammation of sinus, eyes, lungs and nose, thereby resulting in sneezing, wheezing and running nose. Dust mite allergy can be mild or severe with pain in the face, nasal congestion, postnasal drip and inflamed blue skin under the eyes.

Patients with asthma experience a severity in the condition with dust mite allergy. Shortness of breath, wheezing and congestion of the lungs, due to the constriction of the airways are seen to occur. Asthmatic attacks are common, especially in the nights, due to infection from the bed. Extreme cleanliness is vital for keeping dust mites at bay.

Keeping a clean bedroom with hygienically washed bedding plays an important role in avoiding an allergic reaction. Medications provided for hay fever is beneficial for providing relief to inflammation. Antihistamines and nasal corticosteroid sprays are helpful. Decongestants containing cromolyn sodium is helpful. Corticosteroids, short acting beta-2 agonists, long acting beta-2 agonists and long acting bronchodilators are recommended for asthmatic reactions, in response to dust mite allergy.

Desensitization to dust mites is prescribed by physicians through immunotherapy or allergy shots, in case of uncontrollable symptoms, such as watery eyes or rhinitis. Extract of dust mite in dosages of once or twice a week is provided. On stabilizing, it is injected once in four weeks. Complete elimination is difficult, though precautionary measures prove useful. Synthetic bed covers are helpful. Covers that are impermeable to allergens are preferred to envelop the mattress and other bedding. Stuffed toys that are washable and easy to maintain are preferred. An air conditioner helps in keeping the humidity low. 30-50% humidity is beneficial.
