Allergic rhinitis : Immunological and neurogenic mechanisms.
Summary of "Allergic rhinitis : Immunological and neurogenic mechanisms."
Allergic rhinitis is one of the most common diseases to affect humans. It is important to note that it is an immunological disease which is associated with significant changes in the mucous membrane of the respiratory tract. Clinical symptoms of allergic rhinitis include sneezing, rhinorrhea, nasal itching, and nasal congestion. The mechanism underlying the development of symptoms associated with allergic rhinitis are complex, including activation and infiltration of inflammatory cells, edema, increased and altered gland activity, nerve terminal activation, triggering of neurogenic inflammation and morphologically detectable remodelling processes in the mucous membrane. Finally, a systematic activation of immune processes also takes place. Thus, allergic rhinitis is clearly a serious disease requiring prompt and effective treatment; moreover, it has been unjustly trivialized to date, not least because of its high incidence.

Medical and Biotech [MESH] Definitions
Rhinitis, Allergic, Seasonal
Allergic rhinitis that occurs at the same time every year. It is characterized by acute CONJUNCTIVITIS with lacrimation and ITCHING, and regarded as an allergic condition triggered by specific ALLERGENS.
Sick Building Syndrome
A group of symptoms that are two- to three-fold more common in those who work in large, energy-efficient buildings, associated with an increased frequency of headaches, lethargy, and dry skin. Clinical manifestations include hypersensitivity pneumonitis (ALVEOLITIS, EXTRINSIC ALLERGIC); allergic rhinitis (RHINITIS, ALLERGIC, PERENNIAL); ASTHMA; infections, skin eruptions, and mucous membrane irritation syndromes. Current usage tends to be less restrictive with regard to the type of building and delineation of complaints. (From Segen, Dictionary of Modern Medicine, 1992)
Rhinitis, Vasomotor
A form of non-allergic rhinitis that is characterized by nasal congestion and posterior pharyngeal drainage.
Astemizole
A long-acting, non-sedative antihistaminic used in the treatment of seasonal allergic rhinitis, asthma, allergic conjunctivitis, and chronic idiopathic urticaria. The drug is well tolerated and has no anticholinergic side effects.
Antigens, Dermatophagoides
Antigens from the house dust mites (DERMATOPHAGOIDES), mainly D. farinae and D. pteronyssinus. They are proteins, found in mite feces or mite extracts, that can cause ASTHMA and other allergic diseases such as perennial rhinitis (RHINITIS, ALLERGIC, PERENNIAL) and atopic dermatitis (DERMATITIS, ATOPIC). More than 11 groups of Dermatophagoides ALLERGENS have been defined. Group I allergens, such as Der f I and Der p I from the above two species, are among the strongest mite immunogens in humans.
