Question
What Are the Diagnostic Criteria for Pediatric Cough Variant Asthma?
Answer
The main clinical manifestation of cough variant asthma is chronic cough, characterized by persistent coughing, which worsens gradually at night or in the morning, without wheezing, and lasts for a prolonged period (more than three months). It is dry and without phlegm, and antibiotic treatment is ineffective. It responds well to bronchodilators or short-term use of corticosteroids.
