About this trial

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.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

mild-to-moderate asthma

age 18 years or older

Disqualifiers

inability to perform spirometry or fractional exhaled nitric oxide (FeNO) test

Trial population

Thai patients aged 18 years or older with mild-to-moderate asthma are included in the study

Trial design

Design model

Cohort

Time perspective

Cross-sectional

Treatments tested in this trial

  • Global Initiative for Asthma (GINA) and Asthma Control Test (ACT) questionnaires

    Other intervention

    GINA and ACT are questionnaires used to assess the level of asthma control.

  • Spirometry

    Other intervention

    Spirometry is a tool used to assess pulmonary function.

  • Fractional exhaled nitric oxide (FeNO) test

    Other intervention

    FeNO is a tool used to assess eosinophilic airway inflammation and asthma remission.

  • Blood eosinophil count (BEC)

    Other intervention

    BEC is a tool used to assess eosinophilic inflammation and asthma remission.

Trial outcomes

Primary outcomes

1

Prevalence rate of mild-to-moderate asthma remission

Prevalence rate of mild-to-moderate asthma remission (%)

Time frame
An average of 1 year

Secondary outcomes

1

Asthma control in patients with mild-to-moderate asthma

Rate of patients with well-controlled asthma. Well-controlled asthma is defined as an Asthma Control Test (ACT) score of 20 or higher.

Time frame
At baseline and at 12 months
2

Airway obstruction in patients with mild-to-moderate asthma

Airway obstruction is assessed using FEV1/FVC ratio on spirometry.

Time frame
At baseline and at 12 months
3

Severity of aiway obstruction in patients with mild-to-moderate asthma

The severity of aiway obstruction is assessed using FEV1 % predicted on spirometry.

Time frame
At baseline and at 12 months
4

Eosinophil airway inflammation in patients with mild-to-moderate asthma

Eosinophil airway inflammation is assessed using blood eosinophil count (cells/µL).

Time frame
At baseline and at 12 months
