Summary

The goal of this observational study is to determine the prevalence of remission among adults with severe 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 questionnaires on asthma symptoms and undergo pulmonary function testing and a blood test once.

Detailed description

This study is a cross-sectional study. Thai patients aged 18 years or older with severe asthma are included in the study. Participants will complete two questionnaires about asthma control: the Global Initiative for Asthma (GINA) and the Asthma Control Test (ACT), and will perform spirometry, a fractional exhaled nitric oxide (FeNO) test, and blood eosinophil counts (BEC).

Conditions
