Impact of air pollution on asthma exacerbations
Study of the Impact of Exposure to Outdoor and Indoor Pollutants in Patients With Asthma
Nantes University Hospital · NCT05525169
This study looks at how air pollution affects asthma patients by tracking their exposure to pollutants at home and outside to see if it leads to more asthma attacks.

What this trial studies
This observational study aims to measure the exposure of asthma patients to both outdoor and indoor air pollutants to investigate the potential link between pollutant exposure and the frequency of asthma exacerbations. The study will involve continuous monitoring of air quality in patients' homes and outdoor environments. By analyzing the data collected, researchers hope to identify patterns that could inform better management strategies for asthma exacerbations related to air quality.
Who should consider this trial
Good fit: Ideal candidates are adults over 18 with a confirmed asthma diagnosis and a history of at least four exacerbations in the past year.
Not a fit: Patients who are active smokers or have other significant pulmonary conditions may not benefit from this study.
Why it matters
Potential benefit: If successful, this study could lead to improved understanding and management of asthma exacerbations related to air pollution.
How similar studies have performed: While there is limited research on continuous monitoring of indoor air quality in asthmatic patients, studies on outdoor air pollution and asthma exacerbations have shown promising results.
