“… 6 7 Alternaria alternata and Cladosporium herbarum can cause type-1 allergic reactions and induce allergic asthma and rhinitis. 8 9 10 The risk of asthma-related death is more than double with high incidence of fungal spores, and Alternaria exposure is a known risk factor for asthma in children and young adults. 11 Grain crops and their harvesting processes are associated with increases in atmospheric concentrations of Alternaria and Cladosporium species, which disperse over a wide area.…”

Purpose Atmospheric fungi are associated with respiratory allergies in humans, and some fungal spores can cause allergic diseases. Environmental and biological factors influence the concentrations of atmospheric spores. In this study, we evaluated the climate change-induced annual variations in fungal spore concentrations and allergic sensitization rates in the Seoul Metropolitan Area over a period of 25 years. Methods Fungal spores and pollen were obtained from Hanyang University Seoul and Guri Hospitals; they were identified and counted for 25 years (1998-2022). The study participants included patients who underwent tests for allergic diseases in both hospitals. Their allergenic sensitization rates were determined via allergic skin prick and serum tests, after which their sensitization rates to allergenic fungi and pollens were calculated. The daily climatic variables were obtained from the Korea Meteorological Administration. Results The total annual atmospheric fungal concentrations decreased in both areas during the period. Simultaneously, we recruited 21,394 patients with allergies (asthma, 1,550; allergic rhinitis, 5,983; and atopic dermatitis, 5,422) from Seoul and Guri Hospitals for allergenic fungal sensitization evaluations over the period. The allergenic fungal sensitization rates decreased annually in both areas over that time `+( Alternaria [3.5%] and Cladosporium [4.4%] in 1998; Alternaria [0.2%] and Cladosporium [0.2%] in 2022). In contrast, the annual pollen concentrations increased with the sensitization rates to pollen in children. Conclusions The atmospheric fungal concentrations decreased annually, with allergic sensitization rate decreasing over the period of 25 years. Allergenic fungal sporulation could decrease with climate changes, such as desertification and drought. Extended monitoring periods and further large-scale studies are required to confirm the causality and to evaluate the impact of climate change.

“…A suitable environment, including temperature, substrate, and high indoor humidity level or water damage, is necessary for indoor mold growth, leading to increased spores of some species that can cause asthma and exacerbate symptoms (73, 74). Outdoor fungal exposure, especially Alternaria and Cladosporium, was associated with persistent, severe asthma and the severity of asthma exacerbations (75)(76)(77)(78). Children with asthma usually have comorbid allergic diseases, with severe rhinitis may be a significant driver of severe asthma.…”

Asthma is a prevalent non-communicable disease that affects both children and adults. Many patients with severe, uncontrolled asthma could not achieve total control despite using anti-asthmatic drugs. There is increasing evidence that allergy to environmental allergens, including both indoor and outdoor allergens, is associated with asthma symptoms and severe asthma. Frequently reported sensitized allergens were dust mites, cockroaches, grass pollens, molds, pets, and rodents in allergic asthma patients, although the patterns of widespread allergens differed from each country. Allergen avoidance is the cornerstone of asthma management, especially in sensitized subjects. This review summarizes environmental allergen avoidance and clarifies their effects on asthma control. Despite contrasting results about the impact of allergen exposure reduction on asthma control, several studies supported the beneficial effects of reducing asthma-related symptoms or risk of exacerbations as a nondrug therapy. Identifying environmental allergens is helpful for asthma patients, and further studies on clinically effective avoidance methods are required.

“…The most widely studied, and some of the most common, UK aeroallergens are Alternaria and Cladosporium species, however, many other fungal spores are prevalent in the atmosphere (e.g. basidiomycetes), and more research is needed to understand the impacts of other fungi (Caillaud et al, 2018; Gabriel et al, 2016; Grinn‐Gofroń et al, 2019; Skjøth et al, 2016). Despite these gaps in our knowledge of airborne fungal spores, it is clear that they can cause a range of human diseases, with allergenic diseases such as childhood asthma being the most common (Caillaud et al, 2018; Harley et al, 2009; Rodrigues et al, 2016; Welsh et al, 2020).…”
