Caring for children with autoimmune blood disorders in France

This study follows adults with autoimmune blood problems like autoimmune hemolytic anemia, immune thrombocytopenia, and autoimmune/neutropenia to see how diagnosis and care work over time. You may be asked to complete follow-up visits for up to 3 years.

This study collects and stores biological samples (a “biobank”) from people with autoimmune cytopenia, so researchers can learn more about the condition. If you qualify, your samples may help future studies and improve care, and it’s based on voluntary consent.

This study looks back at medical records of people with immune-mediated thrombotic thrombocytopenic purpura (TTP), a rare blood clotting disorder. It aims to better understand the disease and how it is treated.

This study looks at blood “biomarkers,” or measurable body signals, in people with autoimmune diseases, vasculitis, or autoinflammatory conditions. The goal is to better understand these illnesses and how they relate to disease activity.

This study looks at immune cells in children who were recently diagnosed with type 1 diabetes. It involves one extra blood draw to better understand how the immune system attacks the pancreas. If you join, no new treatments are given—just observation and analysis of your child's immune cells.

This study looks at how the immune system goes wrong at the very start of two autoimmune conditions in children: ITP (low blood platelets causing bruising) and lupus (which can affect skin, joints, and organs). Researchers will compare blood samples from patients and healthy children to find early signs of disease, with the goal of better understanding and treating these conditions.
