This study is building a large collection of blood samples from people with rare autoimmune diseases—conditions where the immune system mistakenly attacks the body's own tissues. Researchers will use these samples to study the biological patterns in different patients and to understand why people respond differently to treatments. By learning more about these patterns, doctors hope to develop better ways to diagnose and treat autoimmune diseases in the future.
Autoimmune diseases affect millions of people but remain poorly understood, and patients often respond very differently to the same treatments. This study exists to collect the biological information needed to identify patient subgroups and develop more personalized, effective treatments.

You will have blood samples collected as part of your regular medical care and follow-up visits. The main difference is that slightly more blood will be drawn than usual so researchers can study it. Your blood samples and medical information will be stored and used by researchers to look for patterns that help explain how autoimmune diseases work and how different patients respond to treatment.
