Being an immunological disease, the characteristics of allergy are those of specificity and memory. Regardless of whether the clinical manifestation is rhinoconjunctivitis, rhinitis, or asthma, the underlying immunological response disorder is based on the adverse reactions of cells in the immune system upon contact with allergens. These cells are specific for epitopes that are structural parts of allergens present in the allergenic source material. Two types of cells (i.e., T cells and B-cells) produce receptor molecules (i.e., T-cell receptors and immunoglobulin [IgE] antibodies) that, through high-affinity interactions with the allergen, efficiently catalyze the presence of even minute amounts of allergens into clinical symptoms, the extreme consequence of which may be life-threatening to the patient.

After long-term avoidance of the offending foods, many children outgrow their food allergies. Subsequent periodic challenge with asthma foods to avoid, the offending food should therefore be undertaken to determine whether your child remains allergic to it. The results of skin and blood tests tend to remain positive long after symptoms have resolved, so direct challenge with the offending food is usually necessary. (more…)
