Others
NO
To explore the characteristics of asthma phenotypes with airway sensory neuronal dysfunction and establish the clinical significance of comorbid functional gastrointestinal disorders with asthma.
Others
To explore neurophysiological pathologic correlations between asthma and functional gastrointestinal disorders disorders.
Exploratory
Pragmatic
Not applicable
1. To compare capsaicin cough sensitivity between asthmatic patients with and without comorbid FGIDs.
1. To compare clinical backgrounds and inflammation phenotype(peripheral blood eosinophil and neutrophil counts, exhaled nitric oxide concentration, sputum eosinophil and neutrophil counts, cytokines in serum and sputum) between asthmatic patients with and without comorbid FGIDs.
2. To examine the association of capsaicin cough sensitivity, airway inflammation, and other clinical backgrounds with gastric mucosal inflammation, neuronal remodeling, neuropeptide expression, and TRPV1 expression in asthmatic patients with comorbid FGIDs.
3. To explore factors associated with airway neuronal dysfunction (heightened capsaicin cough sensitivity) in asthmatic patients.
4. To compare gastric mucosal inflammation, neuronal remodeling, neuropeptide expression, and TRPV1 expression between patients with FGIDs with and without comorbid asthma.

[Research Flow]
This is a cross-sectional study, and patients are prospectively enrolled. Asthmatic patients will undergo peripheral blood eosinophil and neutrophil counts, total and specific IgE levels, serum preservation, spirometry, airway reversibility test, exhaled nitric oxide concentration measurement, induced sputum test, and capsaicin cough sensitivity test at the time of inclusion. Upper gastrointestinal endoscopy is performed in asthmatic patients with upper gastrointestinal symptoms and suspected comorbid FGIDs. In addition to routine examination, three mucosal biopsies from the normal gastric mucosa are performed for research purposes. The patients will then be included in the asthma group with and without comorbid FGIDs according to the examination by a gastroenterologist. Patients with FGIDs without comorbid asthma will undergo upper gastrointestinal endoscopy at the time of inclusion, and three mucosal biopsies will be taken from the normal gastric mucosa for research purposes.
