Active clinical trials for "Arthritis, Juvenile"

Childhood arthritis is an important cause of pain for affected children and youth (adolescents). Many youth with arthritis also have trouble sleeping. They often struggle to sleep through the night, wake up earlier, and are sleepier during the day compared to healthy children. Our research group, among others, has shown a strong link between sleep and pain. The main purpose of this study is to assess the impact of changing sleeping patterns on pain, and disease activity, in teenagers with arthritis. We think that better sleep will directly lead to better health.

Methotrexate is a cornerstone in the treatment of childhood leukemia. When given in high-dose as part of the initial phase of treatment, gastrointestinal toxicity is a known problem. However when children reach maintenance treatment with low-dose methotrexate this is not described as a significant challenge. Children with juvenile idiopathic arthritis are another patient group receiving low-dose methotrexate. Among these patients gastrointestinal intolerance is such a significant problem that treatment may be ceased. The aim of this project is to create a greater understanding of gastrointestinal intolerance associated to low-dose methotrexate treatment by investigating the differences between these two patient groups, investigating genetic and psychological factors.

The best treatment plan for Juvenile Idiopathic Arthritis (JIA) is often complicated. Patients and clinicians often don't know what is the best treatment strategy for a given patient at a given time. The purpose of this study is to develop a method to analyze data in situations where the treatment and disease state change over time. The researchers will develop a web-based package that will use the methods developed in this study. The package will be easy to use and allow dissemination of the methods to the public.

This CARRA Registry study will create a foundational database for rheumatic diseases of childhood using a novel informatics infrastructure developed as part of the larger clinical project. The creation of a CARRA-wide informatics infrastructure will enable efficient, observational, disease-related data capture across all CARRA sites for pediatric rheumatic diseases. The CARRA Registry study will demonstrate the feasibility of expanding to more data intensive registries for observational studies, comparative effectiveness research, pharmaceutical clinical trials and translational research.

The purpose of this research study is to see if patients with juvenile idiopathic arthritis or seronegative arthritis (and related conditions) mount protective immune responses to the human papillomavirus (HPV) vaccine called Gardasil. The researchers also want to monitor for any increase in disease activity following receipt of the vaccine.

to evalute if therapeutic alliance is related to adherence in JIA

One of the main potential causes of these failures of BP therapy response is the development of Anti-drug Anti-body (ADAb) in some patients. ADAb may decrease the efficacy of BPs by neutralizing them or modifying their clearance and they may be associated with BP-specific hypersensitivity reactions. The prediction, prevention and cure of anti-drug (AD) immunization are thus major goals in BP development. This prospective study (ABI-RA) will assess the occurrence of ADAb using standardized and validated assay(s) and also cellular, genetic and molecular parameters in RA/JIA patients treated with adalimumab, etanercept, infliximab and rituximab or tocilizumab, to address the mechanism of immunogenicity. Patient-related factors that might predispose an individual to an immune response will be taken into account: underlying disease, genetic background, immune status, including immunomodulating therapy and dosing schedule.

To evaluate the safety and tolerability of single subcutaneous injection of Genakumab for Injection in Chinese healthy adult volunteers

Juvenile idiopathic arthritis (JIA) is a serious autoimmune childhood disease that encompasses several types of chronic arthritis. It is the most common rheumatic disease in children and can cause significant short-term and long-term disability, including permanent joint damage. Management of JIA is based on a combination of pharmacologic interventions, physical and occupational therapy, and psychosocial support. Intra-articular steroid (IAS) injection, or injection of steroid medication into an arthritic joint, is a routine therapeutic procedure in clinical rheumatology. Most pediatric rheumatologists currently perform injections based on knowledge of anatomy and by feeling for anatomical landmarks, but results from adult studies on ultrasound (US)-guided technique have suggested a role for using US in treating and managing JIA. The overall goal of this project is to determine the feasibility of a multicenter study comparing US-guided IAS injection with the usual technique of using external anatomic features to improve arthritis symptoms in JIA. The key issues that this pilot project will determine will be: 1) the ability to use US to successfully image and detect abnormalities in the joints in children with JIA 2) image the injected medication in the joint space or its surroundings immediately after the injection 3) determine methods to measure the clinical response to injection 4) evaluate the feasibility of using saved US scans to localize injected medication in or around the joints and to determine abnormalities concerning for arthritis. These results will be used to establish the protocols necessary to design a multicenter study to determine the effect of US-guided IAS injection in the treatment of juvenile arthritis. Studies regarding the applicability and feasibility of musculoskeletal US in an outpatient pediatric rheumatology setting are important in order to establish the utility of this new technology in guiding diagnosis and therapy in JIA. Results from this study may have a significant impact on pediatric rheumatology and the way by which pediatric rheumatologists currently assess signs of arthritis and perform routine therapeutic procedures.

Juvenile idiopathic arthritis (JIA) is the most common form of arthritis in children. The etiology is unknown. Several types of arthritis fall under the JIA heading. Oligoarticular JIA with antinuclear antibodies affects about half of all children. There 's no specific markers. Our purpose is to identify new markers in this pathology. The ProtoArray®Human Protein Microarray allows rapid and efficient detection of protein interaction using a suitable protein or small molecule probe. The investigators hope so detect novel potential autoantigen biomarkers specific in JIA.
