Active clinical trials for "Arthritis, Rheumatoid"

Rheumatoid arthritis (RA) is a chronic, systemic autoimmune disease affecting the joints and can lead to joint pain, swelling, redness and stiffness and can cause deformity, loss of strength and immobility. This cross-sectional qualitative study aims to explore the burden of established RA by conducting semi-structured Concept elicitation (CE) interviews (60 minutes duration) and real-time data capture task. The conceptual model developed from this data will be used to support the development of GSK3196165, a recombinant human monoclonal antibody (mAb) targeted for the treatment of RA. The CE interviews will explore the subject experience of RA and will collect information about symptoms, disease impact on functioning and health related quality of life (HRQoL), and treatment experiences/impacts of the condition and the language used by subjects to describe them. Following the CE interview, subjects will be asked to complete a brief symptom ranking exercise where they will need to rank how bothersome each RA symptom is and how important it would be to improve with treatment on a 1-5 numerical rating scale (NRS). After the interviews, the real-time disease experience of subjects will be captured by the real-time data capture app-based activity over a period of 7 days. Approximately 30 English-speaking subjects from the United States (US) with RA who are inadequate responders of conventional synthetic disease-modifying anti-rheumatic drugs (csDMARDs) and/or (bDMARDs) will participate in the interviews and of these, 10 subjects will be offered the opportunity to participate in the real-time data capture sub study.

Objective: To evaluate what factors contribute to social participation restrictions in subjects with Rheumatoid Arthritis (RA), considering the model International Classification of Functioning (ICF). Methods: Cross-sectional study with 81 individuals with Rheumatoid Arthritis, using instruments to measure two constructs of component social participation.

Background: Pulmonary diseases are significant contributors to morbidity and mortality in patients with rheumatoid arthritis (RA). One of the most common pulmonary manifestation in RA is interstitial lung disease (RA-ILD). Consequently, RA-ILD may be prevalent in approximately 30% and clinically evident in about 10% of RA patients. Since the median survival for patients with manifest RA-ILD is only 6.6 years, feasible methods of detecting early RA-ILD are warranted. Objectives: To determine the diagnostic accuracy of thoracic ultrasound (TUS), using a 14-zone protocol, for ILD in RA patients with respiratory symptoms by using chest high-resolution computed tomography (HRCT) as the reference standard. The secondary aim is to evaluate the diagnostic accuracy for the blood biomarkers surfactant protein-D (SP-D) and microfibrillar-associated protein 4 (MFAP4) in the detection of ILD in this group of patients. Data collection: Participants will be included after signing the informed consent; data will be collected and stored in a REDCap database. Eligibility criteria for participants and settings where data will be collected: Patients eligible for inclusion are consenting adults (≥18 years) diagnosed with RA (according to the 2010 ACR-criteria for RA) and respiratory symptoms indicating RA-ILD, based on the presence of at least one of the following symptoms: unexplained dyspnoea, unexplained cough and/or a residual pneumonia or a chest X-ray indicating interstitial abnormalities in the lung. Whether participants form a consecutive, random or convenience series: Participants form a consecutive series of up to 80 individuals in total. Description of the index test and reference standard: Patients suspected of having RA-ILD will undergo a 14 zone TUS as index test performed by a junior resident in rheumatology, who is certified by the European Respiratory Society in performing TUS assessment. The anonymised images will be stored, and scored by the junior resident and two senior rheumatologists, who have also received training in TUS, as well as a TUS and ILD experienced pulmonologist. Chest HRCT will be the gold standard, i.e. the ILD reference standard. Estimates of diagnostic accuracy and their precision: The two basic measures for quantifying the diagnostic accuracy of the TUS (index) test are the sensitivity and specificity in comparison to the chest HRCT. Statistical tests will be conducted using the McNemar test for correlated proportions.

The purpose of this clinical trial is to prospectively evaluate RA activity using the assessment of change in DAS28 under local conditions in Slovakia in participants who are treated with subcutaneously administered tocilizumab pursuant to the recommendations of the Ministry of Health of the Slovak Republic in order to better assess the disease activity and impairment of the joint function.

Rheumatoid Arthritis (RA) is a chronic and potentially severe autoimmune disease affecting 2 million in the United States. The role of environmental factors in modulating autoimmunity pathogenesis has been clearly described and yet the specific mechanisms of action remain poorly understood. A growing body of evidence implicates microbiota of mucosal surfaces in the development of autoimmune disorders. Various studies have clearly linked RA to periodontal disease. The latter is linked to the red-complex that includes the oral bacterium Porphyromonas gingivalis. And yet there has not been a systematic analysis of the oral microbiota in RA to determine whether there are specific markers for P. gingivalis (and other oral bacteria) that are linked to RA. In this study, the investigators will characterize oral microbial composition (microbiome) and gene content (metagenome) of DNA isolated from oral samples obtained from patients with (i) early stage RA prior to biologics treatments and (ii) subsets of RA patients who are responsive or unresponsive to anti-TNF-alpha therapy. The innovative aspect of this study is going beyond the identification of oral bacterial species, to the level of strains and genes that are associated with these groups. The overall hypothesis is that oral microbial variation exists between individuals that influences development of autoimmunity and autoimmune disease.

This study will establish a comparison in follow-up care of 100 patients between Health Care Practitioners, more specifically the rheumatologist and a trained nurse. The study objective is to show consistency of evaluation between two different health care professionals, a physician and a nurse.

This multicenter, prospective, non-interventional study is designed to obtain an accurate estimation of the drug retention rate of Tocilizumab (TCZ) Subcutaneously (SC) under real-world conditions in participants with moderate to severe rheumatoid arthritis (RA).

This retrospective cohort study will analyze data from multiple large U.S. health insurance claims databases to compare use of tocilizumab to other biologic disease-modifying anti-rheumatic drugs (DMARDs) in real world patients with RA. Using the date of dispensing as the index date, the analysis will compute the time to first event for several cardiovascular outcomes.

The purpose of this study is to use magnetic resonance imaging (MRI) and high-resolution peripheral quantitative computed tomography (HR-pQCT) techniques to look at the damage and disease activity progression in the hand and wrist joints of patients with rheumatoid arthritis. The central hypothesis is that ongoing erosions and cartilage loss in rheumatoid arthritis are due to persistent inflammation, which is poorly detected by clinical examination and markers of systemic inflammation.

To determine if early clinical response at 12 weeks to Certolizumab Pegol (CZP, Cimzia ®) therapy in adult Rheumatoid Arthritis (RA) patients is a predictor of better long term clinical response at 18 months compared with a lack of clinical response at 12 weeks.
