Summary

Agrostis stolonifera is a member of the Poaceae family that produces grass pollens. Poaceae family pollen is a leading airborne biological pollutant and the main cause of pollen allergy worldwide. Cross-reactivity between grass pollen protein and fresh fruit pan-allergens is associated with allergies to foods such as beans, peas, cereals, peanut, melon, watermelon, carrot, and celery.

Epidemiology

Worldwide distribution

Grass-induced pollinosis is the most common pollen allergy in Europe and worldwide. Marked regional variations of grass pollen sensitization are seen between and within individual countries; depending on climate and region, global sensitization rates range from 1–30%. In Germany, 14.8% of adults are affected by hay fever.

Route Of Exposure

Main

Inhalation.

Clinical Relevance

Symptoms of grass pollen sensitization include allergic rhinoconjunctivitis and bronchial asthma.

Cross-Reactivity

Cross-reactivity between grass pollen protein and fresh fruit pan-allergens is associated with food allergies; foods including beans, peas, cereals, peanut, melon, watermelon, carrot, and celery have been shown to cross react with Poaceae pollen.

In addition to cross reactivity among Poaceae species, high cross-reactivity is seen between grass and cereal pollen allergens.
