Summary of "IgE Sensitization to Inhalant Allergens and Its Association with Allergic Diseases in Adults."

Allergic sensitization to inhalant allergens could be considered as a predictor in allergic diseases. The objective of this study was to assess IgE-mediated sensitization to inhalant allergens in allergic and non-allergic adults as well as the evaluation of its association with allergic diseases. This cross-sectional study was conducted from 2013 to 2016 in 604 allergic and 102 non-allergic adults selected from blood donor volunteers in Tehran, Iran. After taking informed consent, a standard questionnaire was filled to determine asthma, allergic rhinitis and/or conjunctivitis and atopic dermatitis in participants. Specific IgE assay to common inhalant allergens was performed for all subjects. Logistic regression analysis was used to evaluate the impact of IgE sensitization on allergic diseases. A total of 371(61.4%) allergic subjects and 41(40.2%) non-allergic patients were males. The weeds (especially saltwort) and grasses (particularly meadow fescue and ryegrass) were identified as the most common inhalant allergens. The prevalence of IgE sensitization to trees, weeds, and grasses was higher in subjects with allergic rhino-conjunctivitis and trees sensitization was a significant factor in them [OR=2.32, 95% CI (1.58-3.41)]. IgE sensitization to any inhalant allergens could be a predictor for allergic rhinitis, conjunctivitis and rhino-conjunctivitis in adults [OR=2.20, 95% CI (1.54-3.15], [OR=1.81, 95% CI (1.28-2.54)] and [OR=2.55, 95% CI (1.72-3.78)], respectively. With an increase in the sum of specific IgE concentrations, the prevalence of allergic conjunctivitis and rhino-conjunctivitis also increased. Our results showed the association between positive specific IgE and its concentration with some allergic diseases which could help physicians to prevent such diseases by recognizing and treating them, particularly in individuals with a positive family history of allergic diseases.

Medical and Biotech [MESH] Definitions

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.

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.

A contact dermatitis due to allergic sensitization to various substances. These substances subsequently produce inflammatory reactions in the skin of those who have acquired hypersensitivity to them as a result of prior exposure.

An inflammation of the NASAL MUCOSA triggered by ALLERGENS.

Allergic reaction to tree nuts and peanuts, including other LEGUMES, that is triggered by the immune system. It includes co-sensitization to other food (e.g., sesame seed).
