Dust mite - allergic

What is an allergy to dust mites?

Allergy is an immune reaction of the body, which, due to its hypersensitivity, responds with a malfunction, a violation of certain parameters of vital activity upon contact with the stimulus. Irritant in this case is the feces of mites and parts of dead individuals. The former contain enzymes Der p1 and Der f1, and the latter contain chitin, which, when inhaled into the air, irritates the mucous membranes of the respiratory system, upon contact with the skin, causes a reaction on their part, and sometimes also enters the gastrointestinal tract, triggering Mechanism of food allergies.



Allergy to dust mites in medical terminology is called tick-sensitization, the most frequent clinical manifestation of which is allergic rhinitis and bronchial asthma. Any manifestation of a clinical allergy requires medical correction, which is preceded by a diagnosis and which is embodied by desensitization.

How is the allergy to dust mites diagnosed?


Any manifestation of an allergic reaction, whether it be rhinitis, dermatitis, conjunctivitis with the features peculiar to them should be the reason for resorting to an allergist or an immunologist. The doctor starts the examination by collecting an anamnesis, during which the correlation of symptoms with seasonal changes, the intake of food or medicinal components, contact with animals and other irritants is excluded.

Thus, there are suspicions of tick-sensitization, which can be reliably judged only after an analysis called provocative skin tests containing a set of basic allergens in the minimum dosage. The reaction to the introduction of allergens isolated from Der p1 and Der f1 enzymes indicates precisely the presence of tick sensitization. It is a quick and easy way to establish a range of allergens for a particular organism. In addition to the basic procedure, the following can be assigned:

• study of levels of total and specific IgE in serum;
• deployed blood immunogram (to determine the quantitative disorders in the content of various types of cells of the immune system, violations of their functional activity);

• microbiological studies (to determine the presence and nature of foci of chronic infection).
