Background Methacholine dose-response curves illustrate pharmacologic bronchoprotection against methacholine-induced airway hyperresponsiveness and can be used to quantitate changes in airway sensitivity (position), reactivity (slope), and maximal ...

Methacholine challenges: comparison of different tidal breathing challenge methods
Tidal-breathing methacholine challenges are now recommended by guidelines, to avoid the bronchoprotective effects of deep inhalation. This study compared different tidal breathing methacholine challenge methods; assessed the agreement between tidal ...

Methacholine induced headache. [PDF]
A lung function technician developed episodes of headache, probably related to the use of methacholine. The headache disappeared with breathing 100% oxygen. Cholinergic agents are known to induce headaches but the mechanism remains unclear. Vascular factors could be implicated.

Low-Dose Oral Ginger Improves Daily Symptom Scores in Asthma
Background/Objective: A significant number of individuals with asthma have poorly controlled daily symptoms and utilize dietary supplements such as ginger in a quest for improved symptom control; however, its effectiveness at improving the control of ...

Approach to the diagnosis and management of suspected exercise-induced bronchoconstriction by primary care physicians [PDF]
Background Exercise-related respiratory symptoms in the diagnosis of exercise-induced bronchoconstriction (EIB) have poor predictive value. The aim of this study was to evaluate how athletes presenting with these symptoms are diagnosed and managed in ...

Staphylococcal enterotoxin sensitization in a community-based population : a potential role in adult-onset asthma [PDF]
Background: Recent studies suggest that Staphylococcus aureus enterotoxin sensitization is a risk factor for asthma. However, there is a paucity of epidemiologic evidence on adult-onset asthma in community-based populations.

Family and twin studies on methacholine hypersensitivity
Essentially all asthmatics demonstrate a marked sensitivity to inhaled methacholine and histamine, termed non-specific bronchial (airway) hyperresponsiveness (BHR).

Use of a vibrating mesh nebulizer for allergen challenge
Background Allergen inhalation tests are a valuable research tool. The allergen dose producing an early asthmatic response (EAR) can be predicted from methacholine responsiveness and allergen skin test endpoint (STE).

Cer24:1 levels are reduced in neutrophilic asthma and inversely correlate with disease severity and airway neutrophilia. Restoring Cer24:1 suppresses pathogenic Th17 differentiation by engaging EP2 on CD4+ T cells, thereby dampening the JAK2–STAT3–RORγt axis and reducing IL‐17 production.
