What is Allergy - Dermatophatgodies Pteronyssinus?

Establishing a diagnosis of an allergy to house dust mites/Dermatophagoides pteronyssinus
Defining the allergen responsible for eliciting signs and symptoms
Identifying allergens:

• Responsible for allergic disease and/or anaphylactic episode
• To confirm sensitization prior to beginning immunotherapy
• To investigate the specificity of allergic reactions to insect venom allergens, drugs, or chemical allergens

CLINICAL INFORMATION

Clinical manifestations of immediate hypersensitivity (allergic) diseases are caused by the release of proinflammatory mediators (histamine, leukotrienes, and prostaglandins) from immunoglobulin E (IgE)-sensitized effector cells (mast cells and basophils) when cell-bound IgE antibodies interact with the allergen.

In vitro serum testing for IgE antibodies provides an indication of the immune response to allergen(s) that may be associated with allergic disease.

The allergens are chosen for testing often depend upon the age of the patient, history of allergen exposure, season of the year, and clinical manifestations. In individuals predisposed to developing the allergic disease(s), the sequence of sensitization and clinical manifestations proceed as follows: eczema and respiratory disease (rhinitis and bronchospasm) in infants and children less than 5 years due to food sensitivity (milk, egg, soy, and wheat proteins) followed by respiratory disease (rhinitis and asthma) in older children and adults due to sensitivity to inhalant allergens (dust mite, mold, and pollen inhalants).
