Background:
Evidence of treatment against cough variant asthma (CVA) is insufficient for the clinical practice in China. We aimed at evaluating the real-world effectiveness of montelukast (MONT) alone or in combination with low-dose inhaled corticosteroids (ICS) and low-dose ICS plus long-acting beta-2-agonists (LABA) for Chinese CVA patients in a multicentre, prospective, cohort study.
Methods:
Adult patients diagnosed with CVA defined as chronic cough >8 weeks with a positive bronchial provocation test and normal chest X-ray findings were enrolled at respiratory clinics. Study treatment followed routine clinical practice. The investigators initiated MONT by 10 mg/day alone or in combination with a low-dose ICS +/- LABA and followed up treatment outcomes for 4 weeks. The primary outcome measure was the change in cough score (CS) from baseline.
Results:
The study enrolled 247 patients (MONT =146, MONT + ICS =38, MONT + ICS/LABA =63). In the primary analysis, the mean change (95% CI) in CS at the end of the study was -1.2 (-1.6, -0.9), -0.9 (-1.5, -0.4), and -1.3 (-1.7, -0.8) in the three groups, respectively. MONT monotherapy had a satisfactory rate of weekly asthma control at the end of the study (83.5%, 95% CI: 75.1%, 89.4%) in the per-protocol analysis. Rates of weekly asthma control were similar in two MONT-based combination regimens (83.9%, 81.4%). Short-acting beta-2-agonist (SABA) user (≥2 times per week) was 16.8% in the MONT group.
Conclusions:
The real-world effectiveness of MONT alone or in combination with ICS or ICS and LABA was acceptable for CVA short-term control.

01:20Asthma: Pathogenesis and Management
Asthma is classified as allergic and non-allergic. Allergens such as dust mites, pollen, and pet dander trigger allergic asthma, while factors like cold air, intense emotions, or exercise can induce non-allergic asthma.

01:25Antiasthma Drugs: Mast Cell Stabilizers and Anti-IgE Drugs
Mast cell stabilizers, such as cromolyn (also known as sodium cromoglycate) and nedocromil (Tilade), are effective drugs in asthma management. These stabilizers hinder histamine release by skillfully obstructing the activation of mast cells and other cellular entities. Notably, they navigate this task without...
