Active clinical trials for "Arthritis"

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.

Rheumatoid patients have higher fall risk than normal population. Several fall risk factors were studied. No previous study investigated the role of musculoskeletal ultrasound as a predictor of fall risk in rheumatoid arthritis.

The project proposes to evaluate a strategy for prioritizing teleconsultation for patients with chronic inflammatory rheumatic diseases during the COVID-19 pandemia. This selection will be done through telephone contact by medical students, supervised by residents and rheumatologists on a patient database. The other objectives are to assess the impact of the pandemia on the physical and mental health of patients classified as being at risk

This study series consists of four related studies and aims to explore and describe many important elements of alopecia areata over three key areas: (1) the current epidemiology of alopecia areata, (2) the prevalence and incidence of psychiatric co-morbidities in people with alopecia areata, (3) the prevalence and incidence of autoimmune and atopic conditions in people with alopecia areata, and (4) the incidence of common infections in people with alopecia areata.

Rheumatoid Arthritis (RA) is a chronic inflammatory disease causing pain, stiffness, swelling and loss of joint function. RA can reduce the ability to perform everyday tasks. This study assesses whether C-reactive protein (CRP)-level has an impact on achieving remission with upadacitinib when used alone or in combination with methotrexate (MTX). This study will also assess the reduction in pain, morning stiffness, fatigue, functionality, health status and impact of RA. CRP is an indicator of inflammation and often used for disease activity monitoring during RA treatment. Upadacitinib is a Janus kinase (JAK) inhibitor indicated for the treatment of adults with moderately to severely active RA who have had an inadequate response or intolerance to methotrexate. This study has two groups - upadacitinib monotherapy and combination. Adult participants with moderate to severe RA will be enrolled. Around 500 participants will be enrolled in the study in multiple sites within Germany. Participants will receive upadacitinib alone or in combination with MTX per their physicians' usual prescription. Individual data will be collected for 12 months. No additional study-related tests will be conducted during the routine physician visits. Only data which are routinely collected during a regular visit will be utilized for this study.

This study aims to identify the nail ultrasonography (NUSG) properties in patients with psoriatic arthritis (PsA) and healthy controls by a participant-based evaluation; to assess feasibility, reliability, and discriminative performances; to explore final scorings; and to determine associations between the NUSG scores and participant characteristics, including demographics and disease-related factors.

Immune aging or immunosenescence is characterized by a loss of T cell clonal diversity and a contraction of naïve T cells with proliferative capacity associated with the functional impairment of many others immune cells as well as a chronic low degree of inflammation. A restrictive T cell repertoire is likely more prone to antigen-mediated exhaustion observed during chronic viral infections. Notably, lymphopenia is the most consistent laboratory abnormality in COVID-19 infected patients and both lung-resident and circulating T cells potently up-regulate markers of T cell exhaustion. It is not clear today if the association of COVID-19 disease severity with age is mainly related with the immunosenescence of infected patients. Interestingly, T cell exhaustion and premature immunosenescence have also been observed in chronic inflammatory diseases such as rheumatoid arthritis (RA). To better understand the immunological mechanisms involved in SARS-Cov-2 pathophysiology, the investigators propose to compare the immunosenescence patterns observed during RA, aging and SARS-Cov-2 infected patients in order to design improved therapeutic interventions.

The aim of the study is to describe the real-world profile of patients treated with adalimumab FK in gastroenterology, dermatology or rheumatology in order to evaluate in this population the predictive factors of therapeutic response (in particular nutritional status) and generate hypothesis between nutritional status and therapeutic response.

Is to investigate the relation between 14-3-3η protein, disease activity, and bone mineral density in female patients with rheumatoid arthritis.

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.
