An allergen is usually an inert substance (e.g. pollen, house dust mite faeces) that in some individuals can trigger the generation of an (inappropriate) antigenic response. Mediated by TH2 lymphocytes, it causes B-Lymphocytes to produce lgE. Subsequent exposure of a sensitized individual to the allergen is therefore able to cross-link IgE antibodies on the surface of mast cells and trigger an immune response and histamine release.

Allergens, or triggers, differ between PAR and SAR. Common triggers in PAR are dust mites, mold, and animal or... [Pg.926]

The first step in managing a patient with AR is to recommend lifestyle modifications. Patients should be encouraged to avoid allergens whenever possible (see Table 59-1). This may be difficult, however, especially for those with PAR who have continuous exposure to allergens. In PAR, several environmental adjustments should be made. For example, patients with sensitivity to dust mites should use impermeable covers for... [Pg.927]

J Seasonal (hay fever) occurs in response to specific allergens (pollen from trees, grasses, and weeds) present at predictable times of the year (spring and/or fall blooming seasons) and typically causes more acute symptoms. Perennial (intermittent or persistent) occurs year round in response to nonseasonal allergens (e.g., dust mites, animal dander, molds) and usually causes more subtle, chronic symptoms. [Pg.910]

Patients sensitive to animals benefit most by removing pets from the home, if feasible. Exposure to dust mites can be reduced by encasing... [Pg.911]
