Using inflammation tests to improve asthma diagnosis in children and adults

PROPULSION SANTE: Inflammometry to Improve the Diagnostic Trajectory in Situations of Suspected Asthma in Children and Adults

Observational Université de Sherbrooke · NCT06981169

This study is testing if measuring certain inflammation markers can help doctors diagnose asthma faster in children and adults who are suspected of having the condition.

What this trial studies

This observational study aims to evaluate the effectiveness of inflammometry, specifically measuring fractional exhaled nitric oxide (FeNO) and blood eosinophil count (BEC), in prioritizing respiratory diagnostic tests for suspected asthma cases. It will include patients aged six and older who have been referred for diagnostic asthma testing at three hospital centers in Quebec. The hypothesis is that utilizing these biomarkers will reduce diagnostic delays for high-risk patients, thereby improving the overall diagnostic pathway and reducing wait times for necessary tests. The study seeks to address the current challenges in accessing timely asthma diagnostics, particularly for those with Type 2 eosinophilic inflammation.

Who should consider this trial

Good fit: Ideal candidates for this study are individuals aged six and older who have been referred by primary care for asthma diagnostic testing.

Not a fit: Patients referred by pulmonologists will not benefit from this study as they do not meet the inclusion criteria.

Why it matters

Potential benefit: If successful, this approach could significantly shorten wait times for asthma diagnosis and improve patient outcomes by facilitating timely treatment.

How similar studies have performed: While the use of FeNO as a diagnostic tool is established in Europe, this specific approach in Quebec is novel and has not been extensively tested.
