Airway microbes and viral infections in children with tracheostomies

Viral respiratory infections in a tracheostomy cohort: Microbiome-host interplay

NIH-funded research Boston Children's Hospital · NIH-11141181

This project looks at how airway germs and the body's response during viral infections affect illness in children who have tracheostomies and use home ventilation.

What this research studies

You would join a group of children with tracheostomies who are followed during viral respiratory illnesses and provide airway samples over time. Researchers will use detailed genetic and RNA methods (metatranscriptomics) to see which microbes are active and how airway cells respond during infection. They will link those patterns to how sick children become and to antibiotic use to determine whether bacterial overgrowths mean true infection. The study aims to find day-by-day airway ecosystem changes that could guide more precise treatments for these high-risk children.

Who could benefit from this research

Good fit: Children with a tracheostomy who receive home ventilation and are at risk for viral respiratory infections are the intended participants.

Not a fit: Children without a tracheostomy, adults, or those with illnesses unrelated to airway microbiome dynamics are unlikely to benefit directly from this study.

Why it matters

Potential benefit: Could lead to better-targeted treatments and clearer guidance about when antibiotics are helpful, potentially reducing hospitalizations and deaths.

How similar studies have performed: Previous work has shown links between airway bacterial dominance and worse viral infections, but applying metatranscriptomic profiling in a tracheostomy pediatric cohort is relatively new.
