Study of atopic multimorbidity in subjects with rhinitis using multiplex allergen component analysis

Area of Science:

• Allergy and Immunology
• Respiratory Medicine
• Clinical Research

Background:

• Rhinitis is a prevalent condition often coexisting with atopic multimorbidities like asthma and eczema.
• Understanding the factors differentiating rhinitis alone from rhinitis with other atopic conditions is crucial.

Purpose of the Study:

• To compare subjects with rhinitis only versus those with rhinitis plus asthma and/or eczema.
• To investigate associations with immunoglobulin E (IgE) sensitization, inflammatory markers, family history, lung function, and body mass index (BMI).

Main Methods:

• Utilized data from 216 adult rhinitis subjects in the European Community Respiratory Health Survey II.
• Assessed multiplex component allergen analysis, total IgE, inflammatory markers (CRP, ECP, FeNO), spirometry, and questionnaire data on rhinitis, eczema, asthma, and parental allergy.

Main Results:

• Subjects with rhinitis and asthma/eczema exhibited higher IgE sensitization (OR 3.44).
• IgE sensitization to perennial and seasonal allergens strongly correlated with atopic multimorbidity (OR 4.50).
• Maternal allergy, high total IgE, and reduced FEV1 were independently associated with atopic multimorbidity.

Conclusions:

• IgE polysensitization and total IgE levels are key determinants of atopic multimorbidity in rhinitis patients.
• Disease-modifying treatments targeting IgE sensitization could reduce the risk of developing atopic multimorbidity.
