This study is trying to understand how asthma and wheezing in children develop and change over time to help create better, personalized treatments for them as they grow up.

What this trial studies

This observational study aims to investigate the underlying mechanisms that determine different asthma and wheeze trajectories in children and their transition into adulthood. By establishing a clinical cohort of children with new-onset wheeze or asthma, the study will utilize standardized instruments and quality control measures across multiple sites to gather data on genetic, environmental, and molecular factors. The goal is to develop personalized treatment approaches that target distinct mechanisms of asthma, potentially leading to secondary prevention early in the disease process.

Who should consider this trial

Good fit: Ideal candidates for this study are children aged 6 months to 18 years with a history of wheeze or a doctor-diagnosed asthma.

Not a fit: Patients with known inborn or perinatal pulmonary diseases or significant respiratory comorbidities may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to more personalized and effective treatments for childhood asthma, improving patient outcomes.

How similar studies have performed: Other studies have shown success in understanding asthma phenotypes, but this specific approach focusing on early childhood and transition to adulthood is relatively novel.
