Summary

This study is collecting blood, urine, and stool samples from 500 children with autoimmune or inflammatory diseases, as well as healthy controls. Researchers will analyze these samples to find molecular patterns that could lead to a tool for better diagnosis and treatment decisions. The goal is to understand why some people get these diseases and why they vary so much.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

What this could lead to

If successful, this could lead to a tool that helps doctors diagnose and choose treatments for autoimmune diseases more accurately.

What could go wrong

This is an observational study, not testing a treatment. It may not directly benefit participants, and the tool may take years to develop or may not work as hoped.
