This study is collecting joint fluid and tissue samples from 50 adults with inflammatory or non-inflammatory bone and joint diseases. Researchers will use both standard and advanced lab techniques to find new biomarkers that could help diagnose rheumatic diseases more accurately …

This study follows 4,000 people with interstitial lung disease (including conditions like pulmonary fibrosis and sarcoidosis) to understand how the disease naturally changes over time. Researchers will collect medical data and blood samples, and compare them to a healthy control …

This study tests a new communication tool called 'Let's Get REAL' that helps children and teens (ages 8-17) and their families talk together about stem cell transplant or cellular therapy decisions. The goal is to see if the tool is easy to use and helpful for families. About 60 …

This study follows up to 5,000 people with autoinflammatory diseases (like NOMID, CANDLE, and juvenile dermatomyositis) and their healthy relatives. Researchers will collect medical history, blood samples, and imaging over 2-5 day visits to learn how these diseases work and find …

This study is looking at 50 children and adults with rare autoinflammatory diseases—conditions where the immune system causes inflammation without a clear reason. Researchers want to find what leads to a faster diagnosis, what factors are linked to these diseases, and which treat…

This study looks at young adults with chronic inflammatory rheumatic diseases who are moving from pediatric to adult healthcare. Researchers want to see if a structured program that includes education workshops and joint doctor visits helps patients manage their own care better. …
