Studies of Natural History, Pathogenesis, and Outcomes in Autoimmune and Inflammatory Diseases Including Juvenile Dermatomyositis
Eligibility: * Patients with known NOMID/CAPS, DIRA, CANDLE, SAVI, CRMO, Still's Disease, and with other yet undifferentiated autoinflammatory diseases. * Healthy adult and pediatric relatives. * Volunteers
Design: Participants will be evaluated at the NIH for 2-5 days. All participants will have a detailed medical history, physical exam, blood tests and other evaluations depending on the extend of their autoinflammatory disease. Participants may also expect the following assessments: 1. Clinical test that help assess organ damage and functional impact such as hearing vision, memory and learning tests. 2. Imaging studies to characterize the organ involvement of the inflammatory disease including: X-rays, CT scans, special MRIs, bone scans. 3. Laboratory evaluations including clinical markers of disease activity, research samples for genetic studies, and blood samples for cytokine/biomarker assessment, and gene expression profiling.\<TAB\> 4. Completion of questionnaires to assess disease activity and quality of life. 5. If indicated, other procedures may be administered that include: a lumbar puncture if CNS inflammation is suspected and a skin biopsy if skin inflammation is present. other gastrointestinal procedures as they are clinically indicated. 6. Patients my have a research skin biopsy taken. Participants may return for a single follow-up visits or for long term-follow up depending on their disease and willingness to be followed long-term. ...
• Patients with CANDLE, SAVI, and JDM who are mutation positive for the disease or fulfill clinical criteria of the disease.
• Patients who fulfill criteria for definite or probable JDM
• Patients with other suspected autoinflammatory diseases
• There is:
‣ 2 years old or older
⁃ Patients or their legal guardians need to be able and willing to give informed consent and a pediatric patient needs to be willing to assent to the protocol whenever possible.
∙ Relatives of patients with autoinflammatory diseases or healthy volunteers may be included for genetic testing. The genetic evaluations will be conducted in collaboration with Dr. Fleisher's laboratory at the Clinical Center laboratory and other groups. We may also collect blood for serum and RNA analyses to establish a cohort of healthy controls that is matched in age, gender and ethnicity to the study patients. Skin biopsies for research may be requested from patients, patient relatives and healthy volunteers
