Understanding the respiratory microbiomes in infants with severe asthma

Dynamique Des Microbiomes Respiratoires Des Voies supérieures et inférieures associée à l'Asthme sévère Des Nourrissons

NA · University Hospital, Rouen · NCT06044051

This study is trying to understand the germs in the lungs of infants with severe asthma to see if a common antibiotic can help improve their condition.

What this trial studies

This study investigates the dynamics of the upper and lower airway microbiomes in infants suffering from severe asthma. It aims to explore the potential dysbiosis and the interrelation of different microbiomes in the respiratory tract, as well as the immune system's role in the development of severe asthma. By analyzing blood samples, expectoration, and nasopharyngeal swabs, the study seeks to uncover new therapeutic targets and improve patient care, particularly focusing on the use of azithromycin as an immunomodulator. The findings could lead to better management strategies for infant asthma.

Who should consider this trial

Good fit: Ideal candidates for this study are infants under 24 months old who are being followed by a pneumo-pediatrician for severe asthma.

Not a fit: Patients with chronic respiratory diseases other than infant asthma or those currently on antibiotic therapy may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved treatment options and management strategies for infants with severe asthma.

How similar studies have performed: While this approach is innovative, similar studies exploring the microbiome's role in asthma have shown promise, indicating potential for success.
