A study to demonstrate efficacy and safety of anakinra in pediatric and adult Japanese patients with Still's disease (Systemic juvenile idiopathic arthritis [SJIA] and Adult-onset Still's disease [AOSD]).
To facilitate clinical, basic science, and translational research projects involving the study of rheumatic diseases.
This multi-center registration study will investigate the clinical characteristics of AOSD population in China , identify possible factors inducing the onset and active condition of AOSD in Chinese population , and identify the new high specific and sensitive markers of AOSD
Background: Inflammatory conditions can cause symptoms like fevers, arthritis, and rash. Systemic juvenile idiopathic arthritis (sJIA) is one of these conditions. So is adult-onset Still s disease (AOSD). Their causes are unknown. Researchers want to learn more about these conditions. This includes genetic changes and environmental factors. Objective: To study sJIA and AOSD in children and adults over time. Eligibility: People with known or suspected sJIA, AOSD, or similar inflammatory condition Design: Participants will be screened with a phone call. Participants will have 1 visit. It may be outpatient or they may be admitted to the clinic. The visit may last up to 5 days. Participants will have: - Medical history - Physical exam - Musculoskeletal exam - Questions about overall health and quality of life, disease activity, functional status, and cognitive ability. Participants may also have: - Pictures taken of their skin, joints, or spine - Blood, urine, and stool tests - Scans or X-rays of joints with arthritis - Chest X-ray - Heart tests - Skin biopsy. The skin will be numbed. The top layers of a small area will be scraped off. Participants who have a joint aspiration may provide a fluid sample. The joint will be prepared, then fluid is removed by needle. A corticosteroid may be injected. Participants who have a bone marrow biopsy may provide sample cells. Participants may be seen by NIH specialists. Members of the participant s family and healthy volunteers may give blood or saliva samples for genetic testing. Participants may repeat some study tests every 6 months.
In healthy subjects, from 50 to 80 % of the serum ferritin is glycosylated [1, 2] . A decrease in the percentage of ferritin glycosylation can be observed in inflammatory diseases, malignancies, infections, or liver disease but is rarely less than 20% [3 , 4] . Percentage of glycosylated ferritin below 20% have been described in patients with adult Still's disease and haemophagocytosis lymphohistiocytic syndromes (HLH). The glycosylated ferritin has been included in the diagnostic criteria for Still's disease in adults. A cut-off of less than 20 % has a sensitivity and specificity of 72 and 69 % respectively , and 35 and 94 % when combined with a total ferritin level greater than 5 times normal value. This parameter was also suggested to be a more specific marker to confirm a diagnosis of HLH than a high ferritin level ( > 500μg / L). However, several limitations of this parameter were highlighted, some conditions making its interpretation difficult : particularly in cases of major hepatic cytolysis and severe sepsis (miliary tuberculosis, lymphoma and disease Adult Still). It is not always possible to distinguish severe sepsis, HLH syndrome and Still's disease. A fine analysis of various glycoforms components of ferritin could be used to distinguish different subgroups of patients. Few data are available on the mechanism of secretion and glycosylation of ferritin, but the investigators assume that the glycosylation patterns of ferritin may vary between different disease states and reflect distinct underlying pathophysiological mechanisms.
