Filter by:Cortisol is a naturally occurring stress hormone, made by the adrenal glands in response to hormones produced by the pituitary and hypothalamus. Man-made forms of cortisol ('steroids', for example prednisolone) have been used for the treatment of rheumatoid arthritis since the 1950s; they are very effective at reducing inflammation. A normal response to taking steroid treatment is that the body needs to make less cortisol. Following treatment with steroids, the system responsible for making cortisol can be slow to wake up. If someone does not make enough cortisol, they are less able to deal with stress and are at increased risk of becoming unwell, or suffering a potentially fatal adrenal crisis. It is not clear how common failure of recovery of the adrenal axis is, how long it can last for or, if any factors might predict which patients are most at risk. This study aims to improve our understanding of hypothalamus-pituitary-adrenal (HPA) axis recovery in patients with rheumatoid arthritis treated with prednisolone. The investigators will also test potential predictive biomarkers of recovery. The study will be conducted in hospital and a clinical research facility. Participants will undergo two visits for blood tests and will also be asked to supply three samples of saliva on six days over the three weeks of the study. A better understanding of the physiology of HPA axis recovery should inform the development of tools which would allow prediction of patients at risk following withdrawal of steroid treatment. Such tools would be useful to improve patient safety.
In rheumatoid arthritis (RA) the clinical response to anti-TNFα is related to an increase in the number or in the function of Treg lymphocytes in the peripheral blood of patients. This observation suggests the central role of Tregs in homeostasis of the immune response during RA. In the literature the Tregs frequency and phenotype in the peripheral blood are well documented, however the analyses done on the Tregs in inflamed environment are still fragmentary or disparate. In this project Tregs phenotype as well as expression of several transcripts will be analysed in order to better characterize the Treg cell subsets within the synovial fluid. Moreover, the local inflammatory cytokines (TNF, IL-6 and IL-1) may affect both the phenotype and the suppressive function of these Tregs and a comparison between peripheral and tissue Tregs will allow us to better understand the cause of functional loss. Outcomes: Primary outcome: Identification and characterization of the Tregs subpopulation present in the synovial fluid for RA patients suffering an episode of acute arthritis. Secondary outcomes: compare the phenotypic and expression profile of the Tregs present in the synovial fluid with the Tregs present in the peripheral blood of RA patients suffering from an episode of acute arthritis.
This prospective, multicenter, observational study will evaluate the use of concomitant glucocorticoid therapy in adults with rheumatoid arthritis (RA) being treated with tocilizumab in daily clinical practice. Participants will be observed for up to 52 weeks after starting treatment with tocilizumab. All visits and assessments will be performed as per routine clinical practice, with no study-specific visits or interventions.
Recent studies show beneficial effect of the inhibition of interleukin-6 (IL-6) activity on vascular and left ventricular (LV) function. The purpose of this study is to investigate whether anakinra, an IL-6 receptor antagonist, improves vascular, endothelial and LV function in patients with rheumatoid arthritis (RA).
This study will assess the feasibility of using cytokine expression profiles in blood samples as a method for evaluating rheumatoid polyarthritis
HL237 is a new autoimmune therapeutic agent for rheumatoid arthritis, including the basic structure of biguanide in metformin, an existing diabetes drug. The immune modulating activity of HL237 was demonstrated in animal model. HL237 is a STAT3 inhibitor and STAT3 is well known for an important regulator inhibiting Th17 cells and activating Treg cells. Therefore, when STAT3 activity is inhibited, it is expected to be able to treat autoimmune diseases such as rheumatoid arthritis. This is the first clinical trial to be conducted for the development of HL237 and this clinical trial is for determining the maximum oral dose of HL237 and assessing safety, tolerability, and pharmacokinetic characteristics for each dose group.
This multi-site registry, centered at Duke University, will enroll pregnant women with autoimmune and rheumatologic diseases. The main goal of MADRA is to identify ways to improve the health of women with rheumatic diseases and their babies during pregnancy. Prior studies demonstrate the importance of increase inflammation prior to and during pregnancy on these outcomes. The future research will seek to better define these risk factors and to identify ways to may improve them.
This is a multicenter, randomized, double-blind phase2 study to evaluate the safety and investigate the efficacy of YRA-1909 in Patients with Rheumatoid Arthritis who are on a stable dose of Methotrexate(MTX) and who have an inadequate response to MTX(MTX-IR).
The aims of the research are: - To predict factors affecting hand dysfunction in patient with rheumatoid arthritis - To study the effect of hand dysfunction on quality of life in patient with rheumatoid arthritis
This is a 12 month prospective, multicenter, post-marketing, observational study to compare the effectiveness of a treat-to-target (T2T) disease management strategy vs. routine care (RC) in adult patients with moderate to severe rheumatoid arthritis (RA) treated with subcutaneous abatacept (Orencia - SC). Patients completing the study will be offered to participate in a 12-month extension of their follow-up provided that this is in agreement with the judgment of the treating physician.
