Filter by:Background: Some diseases cause chronic inflammation with intermittent flares in the body. These are called autoinflammatory diseases. They can cause fevers, rashes, ulcers, and other problems. Researchers want to learn more about the causes and effects of these diseases. They hope this will improve how the disease is managed in the future. Objectives: To understand the underlying immune dysregulation To identify the genetic cause To translate our findings into novel treatments that improve patients disease outcomes Eligibility: Patients with known NOMID/CAPS, DIRA, CANDLE, SAVI, NLRC4-MAS, Still's Disease, and with other yet undifferentiated autoinflammatory diseases. Unaffected relatives of participants with a known or undifferentiated autoinflammatory disease Healthy adult volunteers at least 18 years of age Design: Participants will be screened with blood sample and medical history. They may provide copies of their medical records. Enrolled 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 extent of their autoinflammatory disease. Participants may also expect the following assessments: 1. Clinical tests that help assess organ damage and function such as hearing, vision, memory, and learning tests. 2. Imaging studies to characterize organ involvement of the inflammatory disease including: X-rays, CT scans, special MRIs, and bone scans. 3. Laboratory evaluations including clinical markers of disease activity, research samples for genetic studies, blood samples for cytokine/biomarker assessment, and gene expression profiling. 4. 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, a skin biopsy if skin inflammation is present, and/or gastrointestinal and pulmonary procedures if they are clinically indicated. Participants may return for a single follow-up visit or for long-term follow-up visits depending on their disease and willingness to return. Long-term follow-up may occur for up to 15 years on this protocol.
Background: - Deficiency of the IL-1 receptor antagonist (DIRA) is a condition that causes repeated episodes of inflammation. People with DIRA can have rashes, fever, and joint pain. Most treatments for DIRA are intended to control the immune system to stop these inflammations. There are drugs that can treat DIRA, but they have to be given daily as injections. Researchers want to try another drug, rilonacept, as a treatment for DIRA. It needs to be given only once a week. Rilonacept will be given to individuals who are at least 3 months old and who have DIRA. Objectives: - To test the safety and effectiveness of rilonacept for children and adults with DIRA. Eligibility: - Individuals at least 3 months old who have DIRA. Design: - Participants will be screened with a physical exam and medical history. Blood and urine samples will be collected. Other tests to study pain and movement will be given. Imaging studies such as bone density scans and x-rays may also be taken. - Participants will have a minimum of four to five study visits over 12 months. Those who are on different anti-inflammatory drugs (such as anakinra) will stop taking them before beginning the study visits. - Participants will have rilonacept injections weekly while on this study. The dose will be adjusted as needed to help treat the DIRA symptoms. Participants will keep a diary to monitor their symptoms and any side effects. - Treatment with rilonacept will be given for 1 year. Participants will have study visits to monitor the treatment. They will provide blood samples and have other tests at these study visits.
