Effect of airborne allergens on emergency visits by children for conjunctivitis and rhinitis

Summary

The effect of fungal spores and pollen grains on morbidity from childhood conjunctivitis and rhinitis is mostly unknown. We therefore studied the association between daily concentrations of these airborne allergens and daily emergency visits to a children's hospital between 1993 and 1997. An increase of 551 basidiomycetes spores per m3, or of 72 ragweed grains per m3, was associated with an increase of about 10% in visits for conjunctivitis and rhinitis (p<0.01). Our results suggest that conjunctivitis and rhinitis could be caused by fungal spores and pollens in the air.

    Moreover, higher atmospheric levels of CO2 have been found to increase the pollen productivity of ragweed.14,15 These changes in pollen production result in greater over-the-counter allergy medication use16 as well as more emergency room and outpatient visits for allergic disease.17,18 Climate change worsens air quality in several ways.

    Thus, as a result of the increase in pollen concentrations, ragweed pollen allergy will become an increasingly common health problem across Europe (Lake et al., 2017). Despite this large and growing health problem, very few studies have investigated the associations between ragweed pollen levels and allergy symptoms, and the effect of pollen exposure on childhood rhino-conjunctivitis is largely unknown (Cakmak et al., 2002). In Italy, Albertini et al. (2012) described a correlation between the number of (mainly adult) patients with asthmatic symptoms and the total annual ragweed pollen concentration.

    Traffic related air pollutants (TRAP) have been implicated in the development of asthma and sensitisation to aeroallergens (Bowatte et al., 2015), as well as exacerbations of existing respiratory conditions in children (Evans et al., 2014; Li et al., 2011). Exposure to both outdoor fungal spores and pollen have been shown to increase exacerbations of existing asthmatic patients (Cakmak et al., 2002; Erbas et al., 2012; Pongracic et al., 2010) and of incident asthma and allergic rhinitis (Erbas et al., 2013). Recently there has been great interest in the amount of green vegetation surrounding the home (residential greenness) as a potential environmental component in the aetiology of allergic respiratory diseases.
