There are about 36633 clinical studies being (or have been) conducted in France. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
Giant cell arteritis (GCA) is the most frequent vascularitis after 50 years of age The investigators recently showed that GCA was accompanied by an elevation in Th1 and Th17 response [1]. Even though a quantitative deficit in regulatory TL (Treg) was shown, there are to date no data concerning their precise phenotypic and functional characteristics and notably their ability to inhibit Th1 and Th17 polarisation. The hypothesis of the investigator is that, in GCA, there is quantitative and above all functional deficit of Treg. Recently, progress has been made in the identification of Treg with new markers (CD39), which will make it possible to better identify and to study their specific functions. In this study the phenotypic and functional characteristics of Treg in GCA will be analysed. Better understanding of the role des Treg in GCA should lead to better-targeted treatments for patients with GCA, notably via the blockage of cytokines that inhibit the differentiation and/or function of Treg. The study is classified interventional because a lot of blood samples are taken.
The purpose of the study is to give the proof of concept of the Fibrin structure assay on STA-R® prototype. It aims to identify the parameters which discriminate the pathologic from the normal population. Secondary objectives are to determine the precision of the assay, to record the Fibrin activity, comparatively with thromboelastography on TEG®, in a coagulation activation assay and in a coagulation-lysis assay.
To identify predictive factors of adalimumab (anti TNF) response in patients with luminal Crohn's disease complicated by intra-abdominal and/or pelvic abscess after complete resolution of infection.
This study aims to describe the patient population being treated and evaluate their treatment adherence and treatment outcomes during treatment of scalp psoriasis with Daivobet® gel Applicator for 4 weeks.
The aim of the trial is to study a radiating diagnosis agent used in post surgery when the biological assessment highlighted a residual disease. This is an inter-regional multicentric, prospective study evaluating the benefit of PET F-DOPA imaging in involved node detection compared to standard imaging assessment in patient with medullary thyroid cancer. The purpose of the study is to evaluate the impact and performance of a new PET / CT (computerized tomography ) tracer targeting dopamine receptor in patient with residual ganglionar biological disease after initial surgery of medullary thyroid cancer compared to standard imaging. Obtained data will be compared to the "gold standard" based on : - nodes cytology when they could be punctured - histology when a new surgery will be recommended - surveillance when the 2 first cases will be not applicable (imaging monitoring, evolution of thyrocalcitonin)
The choroid is a richly vascularized conjunctive tissue, providing the nutritive elements to the pigmentary epithelium and the photoreceptors of the retina. It drains 80% of the eye's blood. The choroidal thickness fluctuates according to the state of fullness of its constitutive vessels. The choroid and the neuroretina (separate by the pigmentary epithelium) are intimately linked and are subject to modifications during the ingestion of caffeine and taurine combined. Several authors have shown a significant decrease of the choroidal thickness lasting at least 4 hours after the ingestion of a small coffee. This decrease may be caused by caffeine's vasoconstrictor effect. Taurine is the most abundant amino acid in the retina. Recent studies have shown the importance of this amino acid in the physiology of both, retinal pigmentary epithelium and retinal ganglion cells. RedBull® is an energizing drink, where one single 25 cl can contains 80 mg of caffeine (the equivalent of a coffee mug) and 1 g of taurine. This pilot trial aims to study the variations of the choroidal thickness and to describe possible modifications within the pigmentary epithelium, due to the ingestion of caffeine and taurine. The results of this study will act as a reference for an ulterior trial aiming specific choroidal pathologies of young patients, such as the central serous chorioretinitis.
The aim of this pilot study is to determine, as exhaustively as possible thanks to the continuous and precise recording of heart rhythm, the frequency of de novo atrial fibrillation in septic shock, which is currently unknown, and to identify specific factors that could be associated with the condition. These will be investigated more precisely in a future study. This constitutes the first step in a reflection on the management of Cardiac Arrhythmia by Atrial fibrillation (ACFA) in septic shock in Medical Intensive Care, known as a major prognostic factor for morbimortality, but for which management is uncertain in the absence of reference data.
Over the last decade, high-flow nasal oxygen therapy (HFN) has emerged as a new method to provide respiratory support in children with moderate to severe bronchiolitis. However, any randomized clinical trial (RCT) have demonstrated that earlier support with HFN is superior to standard care including low -flow nasal oxygen therapy to reduce the risk of acute respiratory failure requiring non invasive (or tracheal) ventilation and subsequently the need of PICU transfer.
The current management of ischemic stroke is based on different strategies that may be combined: intravenous thrombolysis in a stroke ICU, intravenous thrombolysis in a telemedicine procedure, endovascular thrombectomy. Given this now rich therapeutic arsenal, it seems necessary to evaluate practices in local care in the field and the impact of these on the prognosis of ischemic stroke victims. The aim of this observational study is to compare these different care practices without interfering with the choice of strategy. A blood sample will also be taken at different times to study the value of growth differentiation factors (GDF) 8, 11 and 15, and Brain-derived Neurotrophic Factor as prognostic biomarkers
Stroke in elderly subjects has a more severe clinical presentation (in terms of frequency of aphasia, hemiplegia or consciousness disorders), and a worse functional and vital prognosis. Patients older than 75 years also show excess mortality. One of the hypotheses to explain this situation is the high level of frailty in this population. Many tools to measure the concept of frailty have been developed. One important dimension of these tools is the nutritional status. Indeed, protein-energy malnutrition in the elderly, though a frequent situation, is also a complex phenomenon. The aim of this study is therefore to analyse the impact of protein-energy malnutrition, as a marker of frailty, on the early prognosis (at 28 days) in the aftermath of stroke in subjects older than 75 years hospitalized in Dijon CHU.
