['FUNDING_U01'] · LURIE CHILDREN'S HOSPITAL OF CHICAGO · NIH-11072972

This study is looking at whether giving soy isoflavones to babies who are at higher risk for asthma can help prevent them from developing asthma and allergies during their first year of life.

What this research studies

This research investigates whether soy isoflavones can help prevent asthma in infants who are genetically at risk. It involves a randomized trial where high-risk infants will receive either soy isoflavones or a placebo during their first year of life. The study aims to determine if this supplementation can lower the chances of developing asthma-related airway inflammation and allergic responses. By focusing on infants with a specific genetic profile, the research seeks to provide targeted prevention strategies for asthma.

Who could benefit from this research

Good fit: Ideal candidates for this research are infants under one year old who have a specific genetic predisposition to asthma.

Not a fit: Patients who are not genetically predisposed to asthma or are older than one year may not benefit from this research.

Why it matters

Potential benefit: If successful, this research could significantly reduce the risk of asthma development in at-risk infants.

How similar studies have performed: Previous research has shown that soy isoflavones can reduce asthma exacerbations in individuals with the relevant genetic profile, suggesting potential success for this approach.
