Study identifies different allergen triggers in children and adults

An international study coordinated by the Medical University of Vienna has identified distinct differences in how children and adults react to allergens. Research published in the journal eBioMedicine indicates that children with respiratory allergies are significantly more likely to be sensitized to house dust mites, whereas adults more frequently react to outdoor pollen allergens.

The study analyzed IgE antibody reactions to 105 different allergen molecules across two independent cohorts: 539 individuals in the Algiers region of Algeria and 272 patients in Istanbul and Samsun, Turkey. In both populations, the pattern remained consistent. In Algeria, adult reactions often involved olive and grass pollens, while in Turkey, olive and ragweed pollens were prominent.

Additionally, the research noted that asthma occurs more frequently in children than in adults within these groups. Lead researcher Rudolf Valenta highlighted the significance of observing this consistent pattern across two different continents.
