The guidelines [1] on using methacholine challenge testing (MCCT) to evaluate for airway hyperresponsiveness (AHR), published in 2000, provided a figure that allowed clinicians to calculate posttest ...
A cutoff of 4 mg/mL or less in the methacholine challenge test would recognize most children suspected of having asthma, according to recent study results. “There was no difference in the number of ...
Obesity is associated with increased prevalence and incidence of asthma, but the mechanism is unknown. Obesity reduces lung volumes, which can increase airway responsiveness, and increases resistive ...

Background Methacholine hyperresponsiveness is prevalent in elite athletes. Comparative studies have hitherto been limited to methacholine, eucapnic voluntary hyperpnoea and exercise. This study ...
Asthma is characterized pathologically by structural changes in the airway, termed airway remodeling. These changes are associated with worse long-term clinical outcomes and have been attributed to ...
A 48-year-old woman with no smoking history reported cough and feeling short of breath with exertion beginning several months before her clinic visit. It was not clear whether she experienced any ...
Peripheral airway response to methacholine was similar among obese adults with and without asthma, although forced expiratory volume was lower for those with asthma, based on data from 53 individuals.
