Food-induced immunoglobulin E-mediated allergic rhinitis

Area of Science:

• Immunology
• Allergology
• Clinical Medicine

Background:

• Food allergies affect 1-2% of adults and 8% of young children.
• Allergic rhinitis impacts 40% of the population, with diet's role debated.
• Research suggests food allergens can trigger allergic reactions by modulating immunoglobulin E (IgE).

Purpose of the Study:

• To investigate the relationship between allergic rhinitis and sensitization to food allergens.
• To identify specific food allergens that may exacerbate allergic rhinitis symptoms.
• To analyze correlations between age, gender, and food allergy prevalence in allergic rhinitis patients.

Main Methods:

• Serum IgE levels were measured in 100 allergic rhinitis patients (aged 10-60) using RIDA® Allergy Screen.
• Patients treated with antihistamines or who were pregnant were excluded.
• Statistical analysis included ANOVA, with p < 0.05 considered significant.

Main Results:

• 63% of patients with allergic rhinitis showed sensitization to common food allergens.
• The highest prevalence of allergic rhinitis and food allergy co-occurrence was observed in the 21-40 age group (53.2%).
• Females (66.2%) were more likely than males (33.3%) to experience food-allergy-induced allergic rhinitis.

Conclusions:

• A significant portion of allergic rhinitis patients exhibit sensitization to food allergens.
• Rice, citrus fruits, black grams, and banana are identified as key allergens.
• Understanding these food triggers can aid in managing allergic rhinitis symptoms, particularly in females and young to middle-aged adults.
