Filter by:The study aims at determining adherence rate to DMARDS and predicting factors affecting treatment adherence among sample of Egyptian patients with RA.
This double-blind, placebo-controlled, multiple ascending dose study is designed to evaluate the safety, tolerability, and pharmacokinetics (PK) of SKI-O-703 in healthy volunteers.
The objectives of this study are to confirm safety and performance of the Anatomical Shoulder Domelock System when used in hemi or total shoulder arthroplasty by analysis of standard scoring systems, radiographs and adverse event records.
Fulfilling by all patients consequently seen by 6 rheumatologists in a same outpatient rheumatology clinic (in at least one month period) of a set of 6 questionnaires, including RAPID3 and pain catastrophizing scales.
This exploratory study aims to assess exposure of healthy subjects to systemic challenge with either LPS or GM-CSF. This will be done by measuring inflammatory mediators and cellular activation markers both in circulation and in skin blisters induced by exposure to cantharidin (an agent that causes blisters). LPS is often used to induce inflammation whereas GM-CSF is a cytokine and a key mediator in inflammatory diseases. In this 2 parts study, subjects will have 2 sessions in each part. Part I of the study is a dose-exploration phase and part II will be a continuation phase to draw more precise outcomes. In session 1, subjects will be randomized to receive either LPS or GM-CSF and will have 2 blisters induced on each forearm followed by blood draws and a blister harvest on each forearm at 24 and 48 hours post-induction. After a minimum of 14 days blister healing period, subjects will return for session 2. In part I, Up to 6 cohorts will be tested and all cohorts will have 2 sessions. For Part I, initially Cohort 1 will proceed with session 1. After their blister healing period, Cohort 1 will return for their session 2 visit in two groups (Group A and Group B) on different days. Group A will be dosed on the same day (one with LPS and one with GM-CSF) and Group B will be dosed on a different day (one with LPS and one with GM-CSF) after group A. Dose-escalation in Cohort 2-6 will be continued until the well tolerated dose has been determined. The same dose will be administered to an additional Cohort in Part II and the same 2-session design will be used. Approximately 24-30 healthy subjects will be enrolled for the study and the total duration of the study for each subject will be approximately 13 weeks from screening to follow up.
The overall goal of this study is to define the phenotype of Interstitial Lung Disease (ILD), and identify factors that predict radiologic progression in those with subclinical RA-ILD, in patients with rheumatoid arthritis (RA). The investigators hypothesize that there are common core elements (e.g. clinical features, genetic variants, and/or biologic markers) between other forms of ILD (e.g. idiopathic pulmonary fibrosis, IPF) and subclinical RA-ILD that places individuals at risk for the development of lung disease.
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).
