Active clinical trials for "Spondylarthritis"

Axial spondyloarthritis is an inflammatory rheumatic disease mainly affecting joints in the spine and the sacroiliac joints. Inflammatory pathways are likely the central link from axial spondyloarthritis to the known increased risk of atherosclerotic morbidity. Positron emission tomography (PET) is the most sensitive method to detect inflammatory foci in clinical practice. A few small studies have demonstrated that PET imaging together with computed tomography (PET/CT) detects inflamed tissues in relevant patient groups. One study suggested that antirheumatic treatment diminishes the inflammation detected in PET/CT. No study so far has disclosed whether aortic inflammation is present in patients with spondyloarthritis, and whether the inflammation would wane with efficient antirheumatic treatment. The current study is aimed to grade the articular and aortic inflammatory signals in the PET/CT imaging before and after antirheumatic treatment of clinically active axial spondyloarthritis. Sixty patients aged 18-75 years with axial spondyloarthritis and radiologic sacroiliitis as detected either by MRI or X-ray will be recruited. Twenty of those are DMARD-naive, and 40 patients have axial spondyloarthritis resistant to sulfasalazine or other conventional antirheumatic drug. In addition, approximately 30 patients without spondyloarthritis but with stable coronary heart disease and approximately 20 healthy controls will be taken as historical controls. All the axial spondyloarthritis patients are PET/CT scanned after inclusion in the study. The DMARD-naive patients (n=20) are started sulfasalazine-based regimen for 12 weeks, which is the time point for a second PET scan for this subgroup. Adalimumab will be commenced for those without remission at 12 weeks. After another 16 weeks, those with adalimumab will be scanned with PET/CT for the third time. The subgroup with active disease in spite of prior conventional treatment (n=40) is also scanned with PET/CT right after the enrolment and after 16-week treatment with adalimumab. The first 15 patients form a pilot group, which is used to check the validity of the power calculation. The project will give essential new information on PET-detectable inflammation in the patients with axial spondyloarthritis. The results will be published in international publication series. The publications will form the basis for a doctoral thesis. Funding for the project comes from Abbvie Ltd.

This is a not interventional, pragmatic, prospective, randomized (cluster) study to evaluate the potential benefit of a Treat to Target approach in comparison to routine treatment (i.e. usual care) in patients with axial spondyloarthritis.

Ankylosing spondylitis (AS) is a rheumatoid disease affecting all segments of the axial skeleton, leading to the complete fusion of all spinal segments - the bamboo-spine. During the last decade biological disease modifying anti-rheumatic drugs (bDMARD) have been successfully introduced to reduce the disease activity. It is unclear whether bDMARD treatment had an effect on spinal fracture risk related to AS. This national registry study will investigate the effect of bDMARD treatment on spinal fracture risk in a national cohort of patients with AS.

The purpose of this Italian multicenter study is to collect prospective clinical data in participants with first diagnosis or confirmation diagnosis of Spondyloarthritis (SpA), according to Assessment of Spondyloarthritis classification (ASAS) criteria, in order to describe SpA characteristics and pattern of clinical presentation.

In 2004 an ASAS for the Assessment of SpondyloArthritis International Society decided to work to improve the criteria for classification of spondyloarthropathies to allow for early diagnosis, Nuclear magnetic resonance imaging (MRI). This approach led to the publication in 2009 of the classification criteria for spondylarthritis, in particular axial spondyloarthritis, as well as a proposal to modify the classification of criteria defined by Mr. Amor (AMOR) and European Spondylarthropathy Study Group (ESSG) criteria, taking into account the potential abnormalities visible in Magnetic Resonance Imaging Nuclear (MRI). The performance (specificity, sensitivity, positive and negative predictive values) of the ASAS criteria was then prospectively tested on a sample of the Metropolitan Caucasian population and this systematic study allowed to estimate the performance of the ASAS criteria in the usual framework Of the French Liberal Rheumatology Consultation. Note that this approach is exposed to a criticism of "circular" approach, indeed the expert who is the gold standard for the diagnosis, uses more or less consciously "criteria" based on the presence of such and such sign, then checks in this selected population the diagnostic validity of these signs. However, no data on the performance of ASAS criteria are available in populations of African descent.

To date, there are no biomarkers in spondyloarthritis that can differentiate between spondyloarthritis and fibromyalgia or other pathologies. Fecal calprotectin is a biomarker that is increasingly used in inflammatory diseases of the digestive tract. A growing interest in this biomarker is emerging in rheumatology, several publications have focused on its interest in rheumatoid arthritis, highlighting an association between serum calprotectin levels and disease activity. In spondyloarthritis, a few studies seem to show that it could be a marker of disease activity. Although a 2012 study found no difference in serum calprotectin levels between subjects with spondyloarthritis and controls. Still others have shown that it could be a predictive factor of radiological evolution in the same disease key. These data support, despite the questionable results of the Klingberg study, the value of this dosage in spondyloarthritis. The objective of this work is to show that this assay could be useful to differentiate spondyloarthritis from other pathologies with similar clinical presentation such as fibromyalgia. Difficulties classically encountered in common practice in rheumatology.

Evaluate the disease activity guided tapering and discontinuation strategies of etanercept (ETN) in patients with ankylosing spondylitis (AS) in 48 weeks.

Treatment failure of Spondyloarthropathies (SpA) leads to marked functional disability, higher rates of morbidity, mortality and poor quality of life. In TB endemic countries effective and safe drugs are to be in hand to manage this group of patients. The aim of this study will be to evaluation the risk of tuberculosis and other infections in refractory SpA patients treated with tofacitinib. After having consent 174 adults will be enrolled. Follow up period will be 9 months (visits 0, 1, 3, 6 and 9). Study subjects (87) will receive tofacitinib (5 mg 12 hourly). Control patients will get etanercept (50 mg subcutaneously every 7 days interval for 1st month then 50 mg in 15 days interval for 2nd month then 50 mg every 21 days interval till final visit. Treatment efficacy assessment tool will be BASDAI, ASDAS-ESR, ASDAS-CRP and ASQoL for quality of life. Occurrences of tuberculosis and serious infection will be the primary end point of this study. The quantitative variables like ESR, CRP, BASDAI, ASDAS-ESR, ASDAS-CRP and ASQoL scores will be computed as mean and SD. Occurrences of TB and infection will be expressed in number and percentage. In between groups according to data distribution, students't test or ManWhitny U test will be done. The P value <0.05 will be considered significant. Each patient will enjoy every right to participate or refuse or even withdraw from the study at any point of time. Anonymity and data confidentiality will be maintained strictly. Ethical clearance will be obtained from Institutional Review Board (IRB) of BSMMU. The expected utility of this study will be; a) reporting on occurrence of TB and other infections in SpA patients with tofacitinib and etanercept, b) if identified safe and effective physician can use the agents without fear, c) for dose spacing of etanercept the cumulative dose will be low might make the drug affordable and also reduce the risk of TB and other infections, d) for spaced follow up schedule there will be minimized physician visit, lab testing etc.

The aim of this study was to determine the status of ovarian reserve in patients with ankylosing spondylitis (AS) using anti-mullerian hormone (AMH) level and antral follicle count (AFC). Women with AS and women controls diagnosed according to the classification criteria proposed by the American-European Consensus Group will be included in the study. Ovarian reserve will be evaluated in terms of clinical findings, AFC and serum AMH and reproductive hormone levels. Researchers predict that the ovarian reserve may be reduced in patients with AS due to the autoimmune process and the pathophysiology of the disease. Serum AMH and ovarian AFC may be useful for assessing ovarian reserve. It is aimed to determine the course of ovarian reserve abnormalities and the best possible biomarkers of reduced ovarian reserve in patients with AS.

In this open-label, multi-center, observational, post-marketing surveillance study, patients with ankylosing spondylitis, psoriatic arthritis, or rheumatoid arthritis received biosimilar etanercept 25 mg twice weekly or 50 mg once weekly in real-world settings. Safety and effectiveness of biosimilar etanercept were evaluated in study participants for a duration of up to 12 months.
