Condition: Cryopyrin-Associated Periodic Syndromes · Amyloidosis · Sponsor: National Institute of Allergy and Infectious Diseases (NIAID)
Background: Anakinra is a drug used to treat people with certain diseases that affect their immune systems. Sometimes anakinra can cause proteins under the skin to clump together. These clumps are called amyloidosis; they can spread to other organs. The only way to diagnose amyloidosis is to remove a piece of tissue (biopsy). Researchers want to find a way to locate amyloidosis in internal organs using positron emission tomography (PET)/computed tomography (CT). Objective: To test a new tracer used during PET/CT scans in people with amyloidosis. A tracer is a radioactive dye injected into the body. Eligibility: Adults aged 18 years or older with amyloidosis from anakinra injections. They must be enrolled in NIH protocol 17-I-0016. Design: Participants will come to the clinic once every 6 months for 2 years. Each visit will be 1 day. They will have a PET/CT scan with the new tracer at each visit: The tracer will be given through a tube attached to a needle inserted into a vein. The PET/CT scanner is a machine shaped like a doughnut. Participants will lie still on a padded table. The table will move in and out of the machine. The scan takes about 1 hour. Radiation from the tracer will remain in the body for 24 hours after each scan. Participants will need to follow rules to avoid exposing pets and other people. Participants will collect a 24-hour urine sample before each visit. They will also have blood tests and a physical exam at each visit. Participants will rece…
