Gut health and multi-joint osteoarthritis in people and dogs

Official title: Is the gut important in multiple joint osteoarthritis? A multimodal investigation in humans and pet dogs

Funded at Univ of North Carolina Chapel Hill · NIH-11381217 · Data updated 2026-11-12

A scientist team will study whether a leaky gut contributes to pain and worsening of osteoarthritis in people who have OA in multiple joints, using both people and pet dogs for insights.

Who could benefit from this research

Could help

Adults with multi-joint osteoarthritis and pet dogs with naturally occurring OA may contribute samples or data.

Less likely to help

People or dogs without OA or with non-joint-related conditions may not benefit from this research.

What this research studies

This project uses human data and a naturally occurring dog model to explore if increased intestinal permeability is linked to multi-joint OA. Researchers will analyze inflammatory signals and gut-derived biomarkers in people and in dogs with OA to understand shared disease mechanisms. The goal is to identify whether gut health could be a target for slowing OA progression and improving comfort for patients. The study leverages a large human cohort and pet dogs to compare findings across species and uncover pathways that drive joint disease.

Why it matters

Potential benefit: If successful, findings could lead to new strategies targeting gut health to reduce OA progression and pain.

How similar studies have gone: Other studies have linked gut inflammation and OA markers, but using natural dog models for multi-joint OA is relatively novel and promising.
