2017, Journal of Equine Veterinary ScienceCitation Excerpt :Although BHR has consistently been demonstrated to be proportional to human asthma severity, the severity of respiratory impairment during an isolated asthma episode reflects the magnitude of airway obstruction, not the magnitude of BHR. Lessons from bronchoprovocation testing to identify BHR in human asthmatics indicate that BHR is not stable, such that failure to detect BHR must be interpreted in the clinical context [53,61–63]. Corticosteroids and withdrawal of the inciting aeroallergen would be expected to decrease BHR, particularly to indirect bronchoprovocation [64,65].

2015, Annals of Allergy, Asthma and ImmunologyHeterogeneity in ragweed pollen exposure is determined by plant composition at small spatial scales
2014, Science of the Total EnvironmentCitation Excerpt :The effects of these allergies go far beyond the nuisance of physical discomfort; each year, allergies cause 3.5 million lost workdays, 2 million lost school days, and more than 11.2 billion dollars in treatment costs (Nathan, 2007). Furthermore, pollen exposure increases the risk of developing asthma and can trigger fatal asthma attacks (Boulet et al., 1983; Huynh et al., 2010; Zeldin et al., 2006). Pollen allergies have been found in about 40% of asthmatic 1 to 3 year old children (Ogershok et al., 2007), 80–90% of asthmatic children in general, and 40–50% of adult onset asthmatics (Taylor et al., 2007).
