Filter by:Patients can potentially monitor disease activity of rheumatoid arthritis (RA) through self-assessed swollen joints (clinical synovitis)joint counts but reliability of joint swelling is poor. The objective is to evaluate the use of education by ultrasound feedback on the ability of patients to assess for clinical synovitis swollen joints in RA.
Foot silicone implants suffer from bad reputation on the market, due to poor results obtained with the first generations of implants. Allergies to silicone, infections due to silicone and implants breakage used to be common with previous generations of silicone implants. Publications relative to those implants showed that the survival rates after 5 years of follow-up were unsatisfactory. Since 1998, Tornier has been selling a new generation of silicone implants made of Ultrasil™. The use of this new material in its manufacturing process together with its innovative geometry, make the Primus™ FGT a much more resistant, anatomic and long lasting implant. The main objective of this study is to evaluate the clinical outcomes of the implantation of Primus™ FGT implant in great toe arthroplasty. The study will capture long term outcomes in terms of functional metrics from documented clinical data. Other objectives are to evaluate the outcomes in terms of radiological evaluation and of safety during all the follow-up.
Rheumatoid arthritis (RA) is a systemic disease, which mainly targets joints and results in osteoarticular destruction and serious disability. When clinical symptoms (painful and swollen joints) occur, the innate and adaptive immune responses against self antigens have already been largely amplified. This might explain that even when RA patients are treated very early and aggressively, a remission of the disease can only be obtained in approximately half of them. This proportion of remission under treatment can only be achieved using treat to target strategies involving biologics, such as anti-TNF. Unfortunately, less than 20% of patients remain in remission after treatment discontinuation. Thus, despite the availability of 5 different types of biologics, there are still therapeutic unmet needs. However, a spontaneous, drug-free decrease of disease activity can be observed in a physiological condition, pregnancy. Although most of treatments of RA have to be discontinued during pregnancy, a marked improvement, and sometimes remission, can be observed during pregnancy, with frequent post-partum flares. The situation is the opposite with an increased risk of flares in systemic lupus erythematosus (SLE), a rare systemic autoimmune disease which generally progresses in flares-up and can affect nearly any organ (the skin, joints, kidneys, the brain, the heart, …). The course of the disease remains unpredictable for a given patient, and very few biomarkers are available to help clinicians to identify patients a risk of flares. Thus, safe therapeutic options remain limited, especially in patients with serious complications. A specific concern in SLE is the fact that the disease usually starts in women entering their sexual and reproductive life. Even with a stable condition (i.e : lupus without recent flares and no impaired renal or cardiac function) as it is medically recommended before getting pregnant, up to 40% of SLE patients flare up during pregnancy. We hypothesize disease-specific and pregnancy-induced epigenetic changes, especially those regarding the pattern and levels of microRNAs, could explain the clinical improvement and the risk of flares in RA and SLE, respectively. A better understanding of the underlying mechanisms could help to identify new biomarkers, notably those predicting flares in SLE, and therapeutic targets, by trying to mimicking or amplifying micro-RNA changes observed in RA and targeting them in SLE.
This is an adaptive Positron Emission Tomography/ Computed Tomography (PET/CT) and Dynamic Contrast-Enhanced Magnetic Resonance Imaging (DCE-MRI) open-label study design for the investigation of inflammation in adult rheumatoid arthritis (RA) patients, not involving therapeutic intervention. Each study participant will undergo two half body PET/CT scans from the pelvis to the bottom of the feet (including hands and wrists) with an additional bed position centred on the shoulders. One scan will be conducted with 18F-FDG and the other with 18F-GE-180. The first PET/CT scan (PET1) will be performed 4 weeks (28 +/- 2 days) after the first screening visit, whereas the second PET/CT scan (PET2) will be carried out within 2 weeks (7 +/- 7 days) after PET1. The order of PET/CT scans for each subject will be based on a computer generated randomisation schedule after the screening visit. A sub-group of study participants will be invited to undergo an additional dynamic 18F-GE-180 PET scan of a selected joint (knee or wrist) prior to their 18F-GE-180 PET/CT half body scan. The primary objective of the study is to quantify inflammation in joints of RA patients by determining 18F-FDG and 18F-GE-180 uptake using PET, and DCE-MRI parameters.
The purpose of this study is to determine the impact that treatment with a cellular concentrate derived from an individual's own fat, known as the stromal vascular fraction (SVF), has on pain and functionality in people with rheumatoid arthritis (RA). SVF contains multiple cellular components, including stem cells, with both regenerative and anti-inflammatory properties. This therapy has shown promise for ameliorating the symptoms of RA. This study is designed to evaluate changes in pain and functionality in individuals with RA for up to 12 months following SVF treatment.
This is a prospective, randomized, multicenter clinical study in Chinese subjects to compare the safety and efficacy of the Delta PLUS Femoral Head and SL-TWIN Stem with BIOLOX forte ball head and SL-PLUS Stem in total hip arthroplasty
The Primary objective of this study is to understand the rheumatoid arthritis (RA) population in national integrated delivery network who are treated with first- or second-line biologic disease modifying anti-rheumatic drug (bDMARD) therapy (with or without Methotrexate) and to evaluate switching patterns and reasons for switching to another bDMARD.
This study will evaluate whether the effect of personalized patient counselling tool, Information-Motivation-Strategy (IMS) based on the results of the Beliefs about Medicines Questionnaire (BMQ) will improve persistence of Enbrel (etanercept) therapy at week 52 in subjects with rheumatoid arthritis over the historical control as estimated by the standard of care.
The purpose of this study is to determine how effect lacosamide is in reducing the amount of pain medication needed following a total hip arthroplasty. The study team hypothesizes that a single dose of lacosamide will reduce the amount of pain medication required after surgery. The study team plans to evaluate the amount of pain medication needed and quality of pain control during a subject's hospital stay and at their three month follow-up visit following their surgery.
To evaluate the contribution of the assessment of endothelial dysfunction (ED) in improving coronary hearth disease (CHD) risk stratification obtained by the Framingham risk score (FRS) in rheumatoid arthritis population (RA).
