Active clinical trials for "Arthritis, Rheumatoid"

The purpose of this study is to investigate how RA affect the brain structures in RA-patients and if anti-inflammatory treatment that target TNF-α or JAK OR physical training of hands has positive impact on neuropsychiatric symptoms and morphological changes in the brain caused by the disease. The goal of this research project is to improve the knowledge of morphological changes in brain developed in connection to RA and to identify clinical and serological markers to predict development of those changes and finally, to investigate if anti-rheumatic interventions counteract destructive processes in the central nervous system (CNS) and improve the patient's health with respect to functionality, pain experience and psychological well-being.

The purpose of this study is to evaluate the superiority in efficacy of abatacept compared with adalimumab, on background methotrexate, in adults with early, seropositive, and shared epitope-positive rheumatoid arthritis and an inadequate methotrexate response.

A randomized, double-blind, placebo-controlled trial including 160 consecutive patients who have been diagnosed with both rheumatoid arthritis (RA) and low bone mass and have been treated with alendronate (ALN) for five years or more. Patients will be randomized to discontinuation or continuation of alendronate. Outcomes are measured using dual energy absorptiometry (DXA), High Resolution peripheral Quantitative Computer Tomography (HR-pQCT) and biochemical markers of bone metabolism and inflammation after 6 months, 1 and 2 years.

This study is a comparison of quantitative Tc 99m tilmanocept imaging with IHC analysis of CD206 expression in synovial tissue of RA subjects.

Background: Inflammation can play a role in diseases like heart disease and rheumatoid arthritis. PET scans can help detect inflammation. Two new drugs may create better PET images. Objective: To see if the drugs [11C]ER176 and [11C]MC1 can help image inflammation. Eligibility: People ages 18 and older with rheumatoid arthritis or idiopathic inflammatory myopathy (IIM). Healthy volunteers enrolled in protocol 01-M-0254 or 17-M-0181 are also needed. Design: Healthy participants will be screened under protocol 01-M-0254 or 17-M-0181. Participants with arthritis or IIM will have a screening visit. This will include: Medical history Physical exam Blood and urine tests Possible CT or X-ray: A machine will take pictures of the body. Healthy participants will have 1 or 2 visits. They may have urine tests. They may take the drug celecoxib by mouth. They will have a PET scan. A small amount of one or both study drugs will be injected through a catheter: A needle will guide a thin plastic tube into an arm vein. Another catheter will draw blood. They will like on a bed that slides into a machine. Their vital signs and heart activity will be measured. Participants with arthritis will have up to 2 visits after screening. They may take celecoxib and have PET scans. Participants with IIM will have up to 3 visits after screening. At 1 or 2 visits, they will take celecoxib and have PET scans. They will have 1 visit where they have an MRI: They will lie on a table that slides into a machine. The machine takes pictures of the body.

Evaluation of a new screening method for sarcopenia in rheumatoid arthritis

Rheumatoid arthritis (RA) is known as a long-lasting inflammatory autoimmune disease affecting the diarthrodial joints, which is diagnosed by inflammation and hyperplasia in synovium, generation of RF and anti-citrullinated protein antibody (ACPA), deformity of cartilage and bone, systemic injuries involving cardiovascular, pulmonary, psychological, and skeletal disorders (McInnes and Schett., 2011).

The objective of this study is to elucidate the relationship between inflammation and lipoprotein atherogenicity, and to determine the relative contribution of inflammation and lipids to CV risk in RA. The central hypothesis of this study is that inflammation and lipoprotein atherogenicity is tightly linked such that both factors are important to assess CV risk in RA. Further, the investigators hypothesize that this relationship is obscured by a consideration of routine lipids alone.

The main objective of the study is to determine the influence of patient sera before and after probiotic intervention on the behavior of bone cells (osteoblasts and osteoclasts). The secondary objectives are to assess the activity of bone cells and the course of rheumatoid arthritis before and after the consomption of probiotics.

To determine factors associated with early RA-ILD (which may be asymptomatic). It is planned to recruit all patients with a newly diagnosed RA (symptoms since less than 3 years). In this study, all relevant demographic and clinical data will be collected. All patients will undergo lung function tests and high-resolution CT-scan of the lungs. Blood sample will be collected for measurement of (1) anti-CCP and rheumatoid factor measurement (good clinical practice) and a specific sample for the detection of the MUC5 promoter variant rs35705950. Our aim is thus to identify determinants of RA-ILD in the following population: Adults aged 18 to 90 years-old Diagnosis of rheumatoid arthritis (RA) based on ACR-EULAR 2010 criteria Onset of disease duration at least 1 year and at most 10 years prior to inclusion
