By using biomarkers to clarify the pathophysiology or phenotypes that are predominantly involved in individual patients with chronic cough, we aim to establish treatment selection criteria tailored to each individual patient with chronic cough.

Patients whose cough VAS has improved by 30 or more or 50% or more from the pretreatment value at 12 weeks after the start of treatment are defined as the responders, and the other patients are defined as non-responders. Comparing clinical characteristics and biomarkers at the baseline between the responders and the non-responders.

[Research Flow]
We will select patients with a narrowly defined chronic cough who are first-time visitors to our outpatient asthma and chronic cough clinic and for whom a cause cannot be easily identified after medical interview, physical examination, and chest X-ray (chest and sinus CT, bronchoscopy, and echocardiography, if necessary). Patients who consent to the study will be evaluated by spirometry, airway reversibility test, peripheral blood eosinophil and neutrophil counts, total and specific IgE levels, exhaled NO measurement, induced sputum test, capsaicin cough receptor sensitivity test, sputum and serum ghrelin levels, serum vitamin B12 and various questionnaires.
Thereafter, after 12 weeks of thorough evaluation and maximum treatment by a specialist physician, the patients will be sorted into "a group of patients whose cough visual analog scale (cough VAS) has improved by 30 or more or by 50% or more from the pre-treatment value" and "other groups" and baseline clinical indices will be compared between the two groups.
Serum and induced sputum supernatants will be frozen and stored at -80. Serum biomarkers (ATP, HMGB-1, hydrogen sulfide, YKL-40, melatonin, CRH, ACTH) and sputum biomarkers (ATP, HMGB-1, hydrogen sulfide, YKL-40, pepsin/bile acids) that may be relevant to the pathogenesis of RCC/UCC patients will also be measured.
