Active clinical trials for "Arthritis, Rheumatoid"

The purpose of this study is to assess whether or not adalimumab (Humira®) can influence pain medication in participants with rheumatoid arthritis (RA), psoriatic arthritis (PsA) and ankylosing spondylitis (AS) with or without comorbidities, which do not constitute a contraindication for adalimumab as stated in the released summary of product characteristics. Therefore it shall be evaluated if pain medication which is used in these participants is changed, reduced or stopped due to adalimumab treatment.

PBMNC DNA is considered a limit above which patients will develop EBV associated post transplant lymphoproliferative disorder. we showed that methotrexate tended to decrease EBV load over time, but this did not reach significance and that TNFa inhibitors did not significantly modify EBV load over time. Our objective is to monitor Epstein Barr Virus load over time in patients with Rheumatoid arthritis under Orencia* (abatacept) or RoActemra* (tocilizumab), to detect possible immunosuppression associated EBV dysregulation, as seen in post transplant lymphoproliferative disease.

The purpose of this study is to determine possible alterations in cardiac function in patients with Rheumatoid Arthritis and Ankylosing Spondylitis under anti-TNF therapy, without clinical heart disfunction at baseline, using highly sensitive non-invasive methods.

This study attempts to identify the genes responsible for rheumatoid arthritis (RA), or inflammation of the joints. It is known that genes play an important role in RA, but their number and significance have not been determined. RA tends to run in families. This study will examine the DNA (hereditary material) of patients with RA and their family members to try to determine which chromosomes(s) contain the genes responsible for the disease. Patients with rheumatoid arthritis and their family members may be eligible for this study. Participants with RA who have a brother or sister with RA will undergo the following procedures: Review of their medical records Medical history Examination of the joints Hand X-rays Blood tests Participants who 1) do not have RA but who have a relative with the disease, or 2) have RA and a relative other than a brother or sister who has the disease will provide a blood sample or a buccal (cheek) cell sample. Cheek cells are obtained by swishing a small amount of mouthwash in the mouth or by lightly bushing the inside of the cheek with a swab or brush. The samples will be tested for rheumatoid factor, DNA studies, and HLA type (a blood type found on white blood cells). Certain HLA types have been associated with an increased risk or severity of RA.

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.

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

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.

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.

Rheumatoid arthritis (RA) is a chronic autoimmune disease that causes joint inflammation and progressive joint destruction. Rheumatoid cachexia is one of the structural manifestations of RA, and consists of a reduction in muscle mass, due to an increased muscle protein catabolism induced by inflammatory cytokines. This muscle mass loss generates an impairment in physical function and functional capacity in RA patients. The aim of study was to verify neuromuscular and functional responses in middle-aged women with RA compared to paired healthy women.

Rheumatoid arthritis is a genuine systemic disease associated with diffuse interstitial pneumopathy and bronchial disorders. According to the literature review, the prevalence of PID on thoracic CT scan is one-third of patients. Diffuse interstitial pneumopathy is responsible for a significant morbidity and mortality, is currently under-diagnosed and its treatment is poorly codified. The lung seems to have a central role in the genesis of rheumatoid arthritis. It also appears that some subtypes of anti citrullinated peptide antibodies are preferentially present in the lungs. The hypothesis behind our project is that one or more subtypes of anti citrullinated peptide antibodies with a preferential tropism for the lung would attack the parenchyma and pulmonary airways. Currently, there are no data on interstitial pneumopathy in black and Afro-Caribbean subjects with rheumatoid arthritis.
