What this trial studies

This observational study aims to assess how the COVID-19 pandemic has affected asthma control in children aged 3-16 years. It will compare current data on asthma exacerbations and control with historical data from prior to the pandemic. The study will involve clinical assessments and the collection of biological and microbiological samples from a sub-population of children experiencing exacerbations. The findings will help understand the indirect effects of the pandemic on pediatric asthma management.

Who should consider this trial

Good fit: Ideal candidates are children aged 3-16 years with a medical diagnosis of asthma who have been followed for at least 6 months.

Not a fit: Patients with chronic respiratory diseases other than asthma may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide insights that improve asthma management strategies for children during and after public health crises.

How similar studies have performed: While the specific impact of the COVID-19 pandemic on childhood asthma is novel, similar observational studies have successfully assessed the effects of environmental factors on asthma control.
