Active clinical trials for "Spondylarthritis"

Axial spondyloarthritis is one of the most common rheumatic diseases and chronic pain and morning stiffness are the main complaints of these patients. Central sensitization is defined as increased response to normal or sub-threshold stimuli of central nervous system and its close relationship with many rheumatological diseases has been demonstrated in several studies. There is no method for the diagnosis of central sensitization is accepted as a gold standard. The clinical scales and quantitative sensory testing (QST) widely is used for this purpose widely. The most commonly used QST types include pressure pain threshold (PPT), temporal summation (TS) and conditioned pain modulation (CPM). The well-known scale used for the evaluation of central sensitization is the Central Sensitization Inventory (CSI) , developed in 2011 for detect central sensitization in chronic pain patients. In this study, it was aimed to investigate the relationship between QST and CSI and sacroiliac MRI changes.

Rheumatoid arthritis and spondyloarthritis (ankylosing spondylitis and psoriatic arthritis mainly) are chronic inflammatory rheumatism (RIC), frequently onset in young adults. The prevalence is respectively 0.3 to 0.8% and 0.4%. or about 600,000 people. The "basic" treatments (DMARDs), essential to control the progression of the disease, are classified into csDMARDs (chemical), the first of which is methotrexate, or bDMARDs (biological). These treatments are immunomodulators and there is an increased risk of severe infection under these therapies. Several vaccinations are therefore recommended by learned societies in patients receiving these treatments, in order to prevent certain infectious risks.In the current pandemic context, the vaccination of these patients against SARS-Cov2 is a major issue in their management and is recommended by the French society of rheumatology. However, many patients express doubts about this vaccination or refuse it. The factors associated with the vaccination will are not known. Better identifying them would make it possible to adapt the information to be given to our patients to promote their adherence.

In this study, the aim was to investigate the relationship between SII and other laboratory parameters with disease activity in AS patients and to discuss its usability in the follow-up and treatment process.

This study included 113 patients diagnosed with ankylosing spondylitis and 110 healthy volunteers. Participants in both groups were evaluated using the 'Diagnostic Criteria for Temporomandibular Disorders (DC/TMD)' diagnostic criteria. In addition, the relationship between temporomandibular joint dysfunction and disease activity was investigated in patients with ankylosing spondylitis.

The main objective is to identify in the candidate regions of differentially expressed genes by comparing the transcriptome of dendritic cells derived from circulating monocytes between cases and controls. Cases and family controls will be matched on the presence of HLA-B27 and depending on haplotype association studies to correlate the differences of gene expression and genetic variations with susceptibility to AS.

The aim of this study is to find out how patients with osteoarthritis, rheumatoid arthritis and ankylosing spondylitis receiving NSAID-therapy are treated and managed by their doctor in usual clinical practice, how patients comply with their treatment and how satisfied they are with their treatment.

Patients with Ankylosing spondylitis more frequently discontinue work. This study measures the impact of Enbrel on work participation.

This is a prospective, open-label, 1-arm, multicenter observational study to determine the dose and time span of Remicade between infusions for ankylosing spondylitis (AS).

This study will explore how genes may influence the severity of ankylosing spondylitis, a form of arthritis that affects the spine. Patients have inflammation of the joints of the spine, which may cause the bones of the spine to fuse, resulting in difficulty performing daily activities. Patients who developed ankylosing spondylitis after age 16 may be eligible for this study. The onset of disease is dated to the first appearance of symptoms of inflammatory low back pain or restricted spinal motion. Patients with a spondyloarthropathy other than AS may not participate. Candidates will be screened with a medical history and physical examination, blood test, and review of their medical records. They will also complete a questionnaire about their disease symptoms and medical history. Those enrolled in the study will return to the NIH Clinical Center at 6, 12, 18, 24, 30, 36, 42, 48, 54, and 60 months after screening for examination of the joints, measurement of flexibility of the spine, and a blood test. They will also complete symptoms assessment and coping questionnaires. At the first study visit (screening visit), x-rays will be taken of the pelvis, lower back, and neck, if recent X-rays (within 1 year) are not available. These x-ray studies will be repeated on all patients every two years during the study (at 24 and 48 months after screening).

The aim of this study is to investigate the sonographic differences in entheses in patients with Rheumatoid arthritis and Axial Spondyloarthropathy.
