How nasal and gut bacteria shape allergic rhinitis in kids

Official title: Integrated role of nasal airway & gut microbiome dynamics in allergic rhinitis

Funded at Massachusetts General Hospital · NIH-11269734 · Data updated 2026-11-12

A pediatric-focused project will follow healthy infants over time to see how the nose and gut bacteria relate to developing allergic rhinitis by age 7.

Who could benefit from this research

Could help

Infants enrolled in or similar to the MARC-43 multicenter cohort, followed through age 2 with long-term follow-up for AR development.

Less likely to help

Children outside the cohort or without longitudinal sample collection may not benefit from these findings.

What this research studies

This study will build on a large, ongoing infant cohort to track changes in nasal airway and gut bacteria from ages 0 to 2 and relate them to later allergic rhinitis. Researchers will use 16S sequencing to profile microbiomes and integrate this with genetic and clinical data to identify patterns linked to AR. The goal is to understand how microbiome dynamics may contribute to AR risk and its subtypes, with the aim of informing prevention or early intervention strategies. Results could help families understand risk factors and pave the way for microbiome-based approaches in pediatric care.

Why it matters

Potential benefit: If successful, the findings could guide early prevention strategies and personalized care for children at risk of allergic rhinitis.

How similar studies have gone: Prior studies linking microbiome profiles to AR risk exist, but this project advances by tracking dual nasal and gut microbiomes over time.
