Active clinical trials for "Arthritis, Rheumatoid"

The purpose of this pilot study is to investigate the possibility of discontinuing adalimumab therapy in patients with rheumatoid arthritis who are in stable remission after treatment with adalimumab in combination with methotrexate.

Rheumatoid arthritis is the paradigmatic immune-mediated inflammatory arthropathy. With respect to rheumatoid arthritis (RA), patients have been described as having inappropriately low spontaneous and stimulated cortisol secretion levels. Serum cortisol levels are decreased in RA patients who are taking prednisolone. Also, in patients RA, of longer duration, glucocorticoid receptor (GR) down-regulation has been reported without any change in cortisol levels. There is a reduced capacity for local reactivation of cortisone to cortisol in RA synovial cells. It is noteworthy that since synthetic glucocorticoids also use same reactivation shuttle (the cortisol-cortisone shuttle), the results also apply to therapeutic glucocorticoids. Glucocorticoids are widely used to treat chronic inflammatory conditions including rheumatoid arthritis. Prednisolone has a greater effect than non-steroidal, anti-inflammatory drugs on joint tenderness and pain, whereas the difference in grip strength was not significant. There are no qualitative differences between the effects of endogenous cortisol and exogenously applied synthetic glucocorticoids, since all effects are transmitted via the same receptor. Cortisol, on the other hand, plays a major role in normal potassium homeostasis. Recent studies have highlighted a role for diet, with suggestions that diets high in caffeine, low in antioxidants and high in red meat may contribute to an increased risk for the development of rheumatoid arthritis. Higher intakes of complex carbohydrates, dietary fiber, magnesium, folic acid, vitamin C and E, carotenoids and other phytochemicals have been shown to offer distinct advantages compared to diets containing meat and other foods of animal origin. The relation of a potassium deficiency to RA is much less well documented. The first person to definitively link potassium with arthritis was DeCoti Marsh. LaCelle, Morgan & Atwater found that the cells of 50 arthritic patients were 30 to 50% lower than healthy people. Our current clinical trial (clinical trial no NCT00399282) shows that most of patients with RA do not have enough potassium intake. This condition may contribute to a subclinical lower serum cortisol, although there is possibility that cortisol serum levels might be unchanged due to a sufficient "cortisol homeostasis" and "potassium homeostasis".

The objective of this study is to evaluate the effect of high fiber multigrain supplementation on the level of clinical disease severity measures, blood inflammatory molecules, and nutritional status changes in RA patients.

People with rheumatoid arthritis have indicated that they would like better support to remain physically active following diagnosis and would welcome a physical activity programmes delivered outside of a secondary care setting by a physiotherapist. With patient input, and based upon previous research in other long term conditions, a physical activity intervention was developed by the researchers for delivery by musculoskeletal physiotherapists in a primary care setting. This proposed proof of concept study will investigate the new intervention and inform a future randomised controlled pilot trial. Four Band 6 musculoskeletal physiotherapists will be trained to deliver the intervention. Subsequently up to 32 patients with a recent diagnosis of rheumatoid arthritis (6 -24 months previously) will be recruited. Each physiotherapist will deliver the 12-week intervention package to a group of 6-8 participants. The participants will be asked to complete some outcome measures at the beginning of the 12-week intervention and again at the end. Following the 12-week programme some of the patients will be asked what they thought of the programme and the outcome measures and whether they have any suggestions for improvement. Those that did and did not complete the programme will be included to ensure a wide range of views. The treating physiotherapists will also be asked about their experiences of delivering the programme as well as what they thought of the training. Based upon these findings the programme will be refined and if appropriate further funding sought to carry out a pilot randomised controlled trial.

The purpose of this study is to evaluate the pharmacokinetics and safety of oral administration of BR9001 compared with BR900A in healthy subjects

Rheumatoid arthritis (RA) is a systemic disabling inflammatory disease, of autoimmune origin characterized by chronic synovial inflammation resulting in joint damage. Treg cell function in patients with active RA is assumed to be impaired, a trend that seems to be reversed by TNFalpha antagonist therapy. Remission is the current treatment goal in RA. An increasing number of patients in clinical trials achieve this goal raising the question whether patients who have been in remission for a prolonged period (sustained remission) still need medication indefinitely. From a decade TNF-blocker therapy have represented a new treatment option for RA patients non responders to conventional DMARDs and some evidence are now available showing that sustainable remission can be maintained achieved after withdrawal of TNF blocker. Objectives: to verify whether in RA patients in prolonged clinical and instrumental remission the percentages of CD4+CD25highCD127low/- T cells could represent a reliable marker of immunological remission and, even more relevant, if the pharmacological reconstitution of this "immune-modulator" Tcell population could contribute to better identify patients with a low risk of relapse after cessation of TNF-blocker therapy. Methods: in RA patients, who fulfilled the 1987 ACR revised criteria, with disease duration ! 5 years, clinical [Disease Activity Score on 28 joints-DAS28 0.56 ×√(TJC28) + 0.28×√(SJC28) + 0.70×ln(ESR) + 0.014×GH.TJC= Tender Joints Count (from 0 to 28); SJC= Swollen Joints Count (from 0 to 28) ESR=Erythrocyte Sedimentation Rate GH= patient's assessment of general health (VAS range from 0 to 100 mm); disease's flare was considered if: DAS44 >=2.4/DAS28 >=3.2.)], instrumental (joint ultrasonography: sites to be explored wrists are II-III metacarpophalangeal joint bilaterally using Power Doppler signal (grading 0-3); any other joint will be studied if symptomatic) and immunological (circulating CD4+CD25highCD127low/-Tcells and inflammatory cytokines levels) examination will be performed in order to asses, at different levels, disease activity status. Expected results: to identify in RA patients treated with anti-TNF an "exit-strategy" from these drugs based on clinical, imaging and immunologic features indicative of a sustained remission and to verify whether such conditions are able to predict a low incidence of relapse.

The objective of this study was to evaluate effectiveness of pharmacist intervention in improving disease knowledge, adherence to treatment, health related quality of life and direct cost of treatment. The study also documented patient satisfaction with pharmacist counselling as a quality control measure. This is a randomized controlled single-blind two-arm trial in patients with rheumatoid arthritis in Karachi, Pakistan. The study will enroll patients with established diagnosis of rheumatoid arthritis over three months. The patients after signing written consent would be randomized through a computer-generated list in control group, i.e., usual care and intervention group, i.e., pharmaceutical care with a ratio of 1:1. The study will take place in three patient-visits over the course of three months. The patients would be intervened by pharmacist in intervention group while those in control group will have usual care. Primary outcomes include change in mean score at follow-up, i.e., week 12, for disease knowledge, adherence to medications and rehabilitation/physical therapy, health related quality of life (HRQoL). The secondary outcomes include change in the mean direct cost of treatment and patient satisfaction from pharmacist counselling. This is a novel study that evaluates the role of pharmacist in improving treatment outcomes of patients with rheumatoid arthritis. The results of this trial could set the foundation for future delivery of care for such patients in Pakistan. The results of this trial would be published in a peer-reviewed journal.

To evaluate the effect of oral itraconazole on the pharmacokinetics of SHR0302 in healthy subjects. To evaluate the safety and tolerability of oral SHR0302 and itraconazole monotherapy and combination use in healthy subjects.

This randomized controlled study aimed to determine the effect of education on disease management on the quality of life, and anxiety and depression levels of women with Rheumatoid Arthritis. The hypotheses of the current study are as below: H0: Education on disease management in women with Rheumatoid Arthritis does not affect the quality of life and anxiety and depression levels. H1: Education on disease management in women with Rheumatoid Arthritis affects the quality of life and anxiety and depression levels. Patients and Methods: The study was conducted with 66 women with Rheumatoid Arthritis (32 intervention, 34 control groups) at the rheumatology clinic and polyclinic of a university hospital between February and October 2019, in the city of Edirne, Turkey. Data were collected with "Patient Information Form", "Rheumatoid Arthritis Quality of Life Scale", "Health Assessment Questionnaire" and "Hospital Anxiety Depression Scale".
