Filter by:Adult Onset Still Disease (AOSD) and Systemic onset Juvenile Idiopathic Arthritis (SoJIA) are two rare multifactorial diseases associated with systemic inflammation. These two forms AOSD and SoJIA are considered to be two facets of the same syndrome, combining four cardinal symptoms [hectic fever> 39 °, arthralgia or arthritis, skin rash, a leukocyte formula with more than 80% of neutrophils]; lymphadenopathy and splenomegaly may also be found. There is an important biological inflammatory syndrome with elevation of the reactive C protein, of serum ferritin with a dramatic drop in the glycosylated fraction. The incidence of the disease is low, around 0.1/100,000 for adults and 0.6/100,000 for children. Its prevalence is approximately 1 to 3/100,000 and 3/100,000 for children, so there are approximately 500 to 1,500 adults and 450 children affected in France. It is subdivided into pediatric and adult forms according to the age of onset before or after 16 years. The prognosis of the disease is functional and vital. Macrophage activation syndrome (SAM) is frequently associated with either the onset of the disease or the initiation of treatment or concomitantly with viral reactivation. The course over time has mainly been studied in children and is variable: regression, course by flare-ups with term regression and chronic joint development. In adults we can also observe these 3 evolutionary modes. However, differences seem to exist between AOSD and SoJIA. The various clinical questions posed by this disease are as follows: - Why does it differentially affect two age groups of the population? - Why is the clinical expression heterogeneous with pure systemic or articular forms, the frequency of SAM, and rare organ damage? - Why is the evolution over time different with resolving monocyclic forms or polycyclic forms and sometimes chronic evolutions? These differences could be explained by distinct underlying pathogenic mechanisms. But at present, the pathophysiology of this entity remains unknown, although several hypotheses can be formulated involving several pathophysiological pathways. The pathogenesis of Still's disease has not yet been elucidated but there is a significant inflammatory reaction without the production of autoantibodies, which makes this disease a form of autoinflammatory syndrome with abnormalities of the innate immunity (activation of macrophages, strong elevations of pro-inflammatory cytokines: interleukins 1 and 18, possible abnormalities of inflammasomes and NK cells). The treatment is based on anti-inflammatory drugs, corticosteroids with the usefulness of methotrexate and anti-TNF in the event of significant joint damage. Interleukin 1 and 6 inhibitors have been shown to be effective in this disease. In adults and children, there are forms that are refractory to treatment, with a risk of AA amyloidosis for these patients. The expected outcomes of this work are to improve knowledge of Still disease and patient management on the following aspects: - Comparison of pediatric and adult forms (which has never been done on a large number of patients), - Better understanding of the pathogenic mechanisms of the disease, - The identification of early diagnostic/prognostic markers, - The possibility of promoting the evaluation of new therapies to come thanks to the constitution of an active file of patients with a standardized follow-up. The ACOSTILL study group is thus a unique collaboration of adult clinicians (rheumatologists and internists) and pediatricians, who have decided to unite their efforts to increase knowledge about the pathogenesis of Still disease in order to better understand the disease and improve care pathways. Many of them participated in the development of the national diagnostic and care protocol published in 2018.
This study is to assess the safety and effectiveness of Xeljanz in Juvenile Idiopathic Arthritis (JIA) patients in routine clinical practice in Korea. JIA patients experience persistent joint pain, swelling and stiffness. This is a prospective observational study. Xeljanz is a JAK inhibitor. It was first approved in 2014 for rheumatoid arthritis patients in Korea. The ministry of Food and Drug Safety in Korea mandates for a drug manufacturer to report the post-marketing surveillance after drug's approval or indication extension. This study is to see the safety and effectiveness of Xeljanz in Juvenile Idiopathic Arthritis patients in routine clinical practice in Korea. This study is seeking patients who: - Are 2 to less than 18 years of age; - Are given Xeljanz for the treatment of JIA. The study sponsor will monitor patients' treatment experience for up to 44 weeks. This will help assess the safety and effects of this study medicine.
Juvenile Idiopathic Arthritis (JIA) remains the most common systemic disorder associated with pediatric uveitis. Studies estimate that 28-67% of patients with JIA-associated uveitis develop ocular complications, with 12% developing poor visual outcome. The only means of improving long term effects of uveitis, is early and aggressive anti-inflammatory treatment, including biologics.
Aimed to be done in the planned thesis to evaluate the dental and periodontal health of patients with newly diagnosed JIA and healthy-periodontal problems with cytokines from saliva and oxidative stress markers non-invasively, and thus, to determine the markers' evaluability in terms of markers in determining the state of inflammation among individuals with and without the disease.
Inhibitors of tumour necrosis factor (TNFa) reduce inflammation in patients with juvenile idiopathic arthritis (JIA), but only 20-40 percent achieve a state of no or very little disease activity. Tailored glucocorticoid joint injections are widely used (usually in general anaesthesia), but no controlled studies have addressed the effect of this approach. In Norway there are unique possibilities for early interventions, rapid escalation of medication and individualised therapy. The investigators aim to find the optimal ways to increase disease control and improve quality of life for JIA patients. The hypothesis is that JIA patients starting TNF-inhibitors with added steroid injection of inflamed joints, will lead to improved outcomes compared to TNF-inhibitors with no joint injections, and that therapeutic drug monitoring, modern imaging and biologic and clinical profiling can be utilised to characterise JIA patients with different anti-TNF responses. MyJIA is a national investigator initiated 48 weeks RCT of JIA patients starting TNF-inhibitors; 202 JIA patients will be randomised at baseline to A) concomitant intra-articular glucocorticoid injections versus B) no injections. Primary endpoint is the rate of sustained remission from weeks 24 to 36. Possible risk factors for not reaching remission will be analysed including clinical characteristics, drug antibodies/serum concentrations, patients' reported health status and preferences, molecular signalling (based on transcriptional, cellular and genetic risk) and synovitis detected by modern imaging (ultrasound and whole-body MRI). Patients will be recruited from all Norwegian health regions through an established collaboration. Unit of Paediatric Rheumatology, Oslo University Hospital, with an extensive research track in this field, will be the coordinating centre. Broad research cooperation across disciplines is established. The trial is highly innovative in evaluating treatment options and strategies to individualise and optimise the efficacy and safety of JIA treatment.
The reason for this study is to see if the study drug ixekizumab is safe and effective in children with juvenile idiopathic arthritis (JIA) categories of enthesitis-related arthritis (ERA) (including juvenile onset ankylosing spondylitis [JoAS]) and juvenile psoriatic arthritis (JPsA).
Far too many kids and families live in dread over the weekly nausea and vomiting caused by methotrexate - a medicine that controls joint swelling in Juvenile Arthritis patients. If methotrexate is not tolerated, expensive alternative biological medications may be started. This registry-based pragmatic randomized controlled trial will evaluate if routine premedication with the anti-emetic drug Ondansetron, reduces nausea and vomiting and increases the proportion of children able to continue methotrexate. By preventing nausea before it starts, the investigators hope to give kids and families a better quality of life and see a more cost-effective use of medication.
The Norwegian JIA Study (NorJIA) is a prospective, longitudinal, multicenter, observational study of 250 children with juvenile idiopathic arthritis (JIA) and 250 healthy controls, attending the three Norwegian university clinics in Bergen, Tromsø, or Trondheim. The study will run over 5 years, and include extensive clinical, laboratory, radiological and oral examinations at baseline and after 2 years follow-up. There will be a special focus on the jaw (temporomandibular joints) with extensive imaging and clinical examination, aiming at establishing scoring systems for active and chronic disease and growth disturbances. Another focus is to study mouth and teeth problems, such as caries and gingivitis, and look for predictors of poor oral health in children with JIA compared to health peers. As chronic inflammation, reduced physical activity and certain anti-inflammatory drugs can be detrimental for bone strength and development, the investigators also want to study the bone health of children with JIA, and look for predictors of poor bone mineral density. The results of the study may contribute to better diagnostics of inflammatory processes, earlier detection of poor oral or bone health, and thereby point to possible prevention strategies to increase quality of life for children with JIA in the future.
This is a research study to test whether a once-weekly injection of abatacept will prevent the progression of Juvenile Idiopathic Arthritis (JIA) to a more severe form. To evaluate the effectiveness of a 24-week course of treatment with abatacept plus usual care versus usual care to prevent polyarthritis (≥5 joints), uveitis, or treatment with other systemic medication within 18 months of randomization in children with recent-onset limited JIA.
Optional open label, roll over extension study to investigate the efficacy and safety of secukinumab treatment in Juvenile Idiopathic Arthritis (JIA) subtypes of Juvenile Psoriatic Arthritis (JPsA) and Enthesitis Related Arthritis (ERA).
