Filter by:Previous studies have analyzed serological responses following pneumococcal vaccination using 23-valent vaccination (Pneumovax) in Rheumatoid Arthritis (RA) patients that were on different therapeutic modalities including TNF-blockers and methotrexate. The results have shown that serological response was significantly reduced in RA patients receiving methotrexate compared to those receiving TNF-blockers. In contrast when using polypeptide immunisation (influenza vaccine) we found that anti-TNF significantly impaired the serological response compared to the methotrexate treated RA patients. The aim of this study is to analyze serological responses after Prevenar vaccination in patients with chronic arthritis and to study the impact of different treatment modalities on serological responses. It will be of interest to see if the result is different compared to the one seen after immunizing with 23-valent nonconjugated pneumococcal polysaccharide vaccine.
The purpose of this study is to evaluate the interest of enthesis sonography for the diagnosis of spondylarthritis, in patients with uncertain diagnosis consulting for clinical symptoms suggestive of spondylarthritis
Up to 60% of patients with Seronegative Spondyloarthritides have inflammation in the colon or ileum. This is usually asymptomatic, but in 5 to 10% of patients with SA, Frank IBD will develop. Lesions of the bowel could also be present in the SA patients because of the potential injury posed by the NSAIDS, a common used medication in this setting. It is the bowel involvement in patients with SA that we propose to characterize, partly because there are scant communicated data in the medical literature, especially regarding small bowel lesions.
This is a multi-national, multi-site, observational study to determine which of two strategies, when used by referring physicians is superior in the diagnosis of axial spondyloarthritis (AS) by rheumatologists.
Subjects will be given 3 infusions of infliximab according to the label at week 0, 2, and 6. Subjects will be followed for a maximum of 18 weeks or until relapse. This study will assess the ability of the Power Doppler Ultrasonography (PDUS) to be a reliable marker of enthesitis response and relapse in subjects treated with infliximab.
Tumor necrosis factor (TNF) alpha is a pro-inflammatory cytokine playing a significant role in the pathogenesis of the spondyloarthropathies (SpA). Infliximab is a TNF alpha blocking monoclonal antibody efficacious and safe as treatment of adult-onset SpA. In this study we will try to demonstrate that infliximab administered at 5mg/kg to patients with juvenile onset SpA over a period of 12 weeks will have more efficacy than placebo and that it will be well tolerated. At the end of this phase, patients will go into a 52-week open extension to demonstrate sustained efficacy, safety, and tolerability of infliximab We will include 34 patients with juvenile onset SpA unresponsive to standard treatment. Efficacy will be assessed by counting the number of actively inflamed joints and a number of other parameters.
A relationship between IBD and spondyloarthropathy is well recognized. ASCA ( anti saccharomyces cerevisiae antibodies)are considered to be a serological marker for Crohn's disease and have been studied in patients with spondyloarthropathy with conflicting results. More recently, new serological markers for IBD have been described. These markers are antibodies to certain defined glycans , and their use may permit an improved diagnosis of IBD. The aim of our study is to investigate wether these new serological markers are present in the sera of patients with spondyloarthropathy.
To assess the efficacy and safety of Etanercept in patients with spondylarthropathy and refractory heel enthesitis.
The purpose of this study is to determine which of the proposed screening parameters or which combination of screening parameters perform best in daily clinical practice for making the diagnosis of axial Spondyloarthritis (SpA)in patients with chronic low back pain.
Background: Existing criteria for AS/SpA such as mod. New York, ESSG, or Amor criteria for classification and/or diagnosis of spondyloarthritis have limitations when applied to early disease. Moreover, MRI is not part of any of the established criteria and the precise role of MRI in early axial disease has not been fully defined yet. Even less is known about sacroiliac (SI) changes in SpA patients with peripheral symptoms. A pilot study using data from 'paper patients' led to new candidate criteria for early spondyloarthritis. Subsequently, the members of the ASAS International Working Group decided to conduct a prospective multi-centre study to evaluate (validate) the new candidate criteria, and to assess their performance as diagnostic criteria. Aims of the study: 1. To evaluate the new candidate criteria for axial SpA in a multi-centre setting. 2. To assess the potential role of the new candidate criteria to be used as diagnostic criteria. To accomplish this, inclusion of consecutive and undiagnosed patients is mandatory as are longer periods of follow-up . 3. To compare criteria encompassing the whole group of SpA such as ESSG and Amor criteria against criteria which are tailored to either predominant axial disease or predominant peripheral disease. To accomplish this, both patients with predominant axial disease (back pain) but also patient with predominant peripheral disease (arthritis/enthesitis) will be included.
