What this Trial Is About
Researchers are collecting biological and clinical data from patients with systemic autoimmune diseases to better understand these complex conditions. These diseases affect a notable portion of adults, mostly women, and involve the immune system attacking the body. The study aims to identify new biomarkers and improve diagnosis and treatment options by exploring the clinical, biological, and genetic differences among patient groups. Participants will provide blood samples during their routine diagnosis and follow-up visits, with a larger amount of blood taken specifically for this study. This observational study focuses on patients with rare systemic autoimmune diseases or atypical forms who may be undergoing innovative treatments such as new drugs, gene therapy, or cell therapy. During the study, researchers will collect biological samples and clinical data and analyze them to find new diagnostic and prognostic markers, predict relapses or treatment responses, and understand disease mechanisms. The study will monitor patients for about one year, with the goal of improving personalized medicine approaches for these autoimmune diseases.
