    Spirometry is a tool used to assess pulmonary function.
  • Fractional exhaled nitric oxide (FeNO) test — OTHER
    FeNO is a tool used to assess eosinophilic airway inflammation and asthma remission.

Study Details

The goal of this observational study is to determine the prevalence of remission among adults with mild-to-moderate asthma, as well as the factors associated with remission in Thailand. The main question the study aims to answer is: What is the prevalence of remission among adults with severe asthma in Thailand? Participants will complete a questionnaire on asthma symptoms and undergo pulmonary function testing and a blood test once.

Arms

  • Arm: Mild-to-moderate asthma
    Patients aged 18 years or older with mild-to-moderate asthma. Mild asthma refers to asthma patients who experience symptoms \<3 times per week, have preserved lung function (FEV₁ or PEF \>80% of predicted), and whose symptoms can be adequately controlled with low-dose inhaled corticosteroids (low-dose ICS) alone, without the need for long-acting bronchodilators or other controller medications. Moderate asthma refers to asthma patients who have symptoms \>4-5 days per week or experience nocturnal asthma symptoms \>1 per week, and who require treatment with medium-dose inhaled corticosteroids (medium-dose ICS) or low-dose ICS in combination with a long-acting β₂-agonist (low-dose ICS/LABA) to achieve symptom control and prevent exacerbations.
