Filter by:Evaluation of two treatment modalities in early potentially severe early arthritis ( Methotrexate alone or in combination with adalimumab)
As one of the characteristic clinical features of the patients with rheumatoid arthritis, the unique character of the patients, somewhat difficult to be persuaded but theoretical, has long been pointed out. The investigators hypothesized that this unique character might be due to the sleep disturbance in the patients possibly due to severe pain of arthritis or unique biochemical disease activities. The investigators test (1) the sleep quality of the patients and draw some characteristic features, and (2) investigated the connection between unique biochemical changes such as the increase of c-fos or wee-1.
1. to investigate, whether one of the two alternative therapy strategies (antibiotic plus immunostimulation versus antibiotic plus immunosuppression) in chronic reactive arthritis is therapeutical superior to conventionel standardtherapy (DMARD). 2. to investigate, whether one or more of the different therapy strategies cause an altered detection of bacterial DNA in the joint or colon. 3. to measure the antigen-specific and -unspecific immune response (predominantly t-cell response) during therapy and correlate it with the clinical course. 4. to gain knowledge from these analyses and the clinical course concerning the pathogenesis and the point of attack for possible therapies in chronic reactive arthritis. 5. to compare cytokine-profiles of CD4- and CD8-positive T-cells from patients treated with infliximab to those treated with etanercept.
The purpose of this study is to establish whether RA patients with moderate to severe disease activity with unsustainable response to infliximab 3 mg/kg every 8 weeks have better efficacy with adalimumab 40 mg s.c. eow compared to infliximab 3 mg/kg i.v. every 6 weeks.
The purpose of this study is to determine whether intra-articular botulinum toxin type A is effective in the treatment of chronic joint pain.
The purpose of this study is to determine whether intra-articular injection of botulinum toxin is effective in the treatment of chronic knee paindue to arthritis.
The purpose of this study is the investigation of the functional and radiological results and subjective patient outcome after the implantation of a hip resurfacing endoprosthesis (Birmingham hip resurfacing).
Although SLE and RA are correlated with genetic predisposing factors such as human leukocyte antigen (HLA) class II, both diseases and other genetic factors might have contributed to the development of dysregulated lymphocyte activation and autoimmunity. Decoy receptor 3 (DcR3)/TR6 is a secreted protein belonging to the tumor necrosis factor (TNF) receptor family. It binds to Fas ligand (FasL), LIGHT, and TL1A that are all TNF family members. It was noted that soluble or solid phase DcR3-Fc co-stimulated proliferation, lymphokine production and cytotoxicity of mouse and human T cells upon T-cell receptor (TCR) ligation. Recently, the investigators found that the serum level of soluble DcR3 was higher in SLE patients than in healthy control subjects (unpublished data). Taken together, the investigators propose that in autoimmune diseases, such as RA and SLE, activated T cells secrete more DcR3 than non-autoimmune controls, which may, in turn, costimulate T cells further and cause dysregulated lymphocyte activation. With the aim to establish the possible correlation between DcR3 genetic polymorphisms, DcR3 expressions, and autoimmune phenotypes, the investigators offer this proposal. They plan to investigate the single nucleotide polymorphisms (SNPs) in the DcR3 gene. The genetic polymorphisms on the DcR3/TR6 gene and circulating DcR3 level will be compared between RA, SLE and non-autoimmune control subjects.
This study will explore the causes of rheumatic diseases and why many of them affect certain minority communities more severely. Rheumatic diseases may cause joint pain, stiffness or swelling. Some can involve bones, muscles, tendons or ligaments. Some cause abnormalities of the immune system the body s defense against disease. Some rheumatic diseases are painful or deforming and some can be life threatening. Information obtained from this study will be used to learn about the disparities in rheumatic disease in the minority community and to design further, more targeted, research studies to address this issue. Patients with known or suspected rheumatic disease 18 years of age or older may be eligible for this study. Candidates will undergo a medical history and physical examination to confirm the diagnosis of rheumatic disease and determine what is needed for evaluation and treatment. Participants will receive standard medical care for rheumatic disease and arthritis. No experimental treatments, medications or procedures will be included in this study. Procedures may include routine blood tests for blood chemistries, cell counts, and antibodies commonly found in patients with rheumatic disease; a urine test for proteins and cells; and X-rays and other imaging tests to check for abnormalities in the lungs or other organs. All medical information will be kept confidential. Patients who are found to be eligible for other current NIH research studies will be offered an opportunity to participate in these studies.
This study will investigate the safety and effectiveness of the drug Enbrel (TNFR:Fc) to treat uveitis (eye inflammation) in patients with juvenile rheumatoid arthritis.
