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.
MOTHIF II is a non-interventional, multicenter, retrospective, observational data collection in seven French Haemophilia Treatment Centers of the BERHLINGO network. In the context of the arrival of new extended half-life products, the MOTHIF II study aims to describe the changes in therapeutic management of patients with hemophilia A & B, following the provision of FVIII and FIX extended half-life factors in France; it will also permit to carry out a budget impact analysis to quantify the economic significance of this new era.
Hypercholesterolemia is a major cardiovascular risk factor. Statins are the first-line drug treatment for hypercholesterolemia and have been shown to be effective in both primary and secondary prevention of cardiovascular disease. However, long-term statin therapy is associated with impaired carbohydrate metabolism and increased risk of developing type 2 diabetes (T2D), particularly in patients with metabolic syndrome. The risk of developing T2D is higher with high doses of statins. Currently the benefits of statins on the reduction of major cardiovascular events and mortality are considered superior to the risk of statin-induced diabetes T2D, and no change in clinical practice has been recommended to date. However, it now appears necessary to develop strategies to reduce the adverse effects of statins on carbohydrate metabolism and maintain the carbohydrate tolerance of patients on statins, especially in those at risk of developing T2D under statins. Statins are able to induce the expression and activity of an enzyme synthesizing nitric oxide (NO), the endothelial NO synthase (eNOS), which helps improving insulin sensitivity and insulin secretion. However, availability and metabolism of its substrate arginine is impaired in obesity and T2D. The investigators thus hypothesized that providing citrulline to statin treated patients, the arginine precursor with better gastrointestinal tolerance and bioavailability than arginine, would beneficially impact their glucose homeostasis. Tested in vivo by Béatrice Morio, a member of the CarMeN laboratory, combining citrulline to atorvastatin improved glucose tolerance and insulin sensitivity in mice fed a high fat-high sucrose diet. These data therefore suggest that combining citrulline to atorvastatin may improve glucose tolerance in statin-treated patients at high risk of developing T2D. The objective of the study is therefore to investigate the impact of citrulline supplementation (5g/d) vs. placebo for 4 weeks on glucose tolerance assessed during an oral glucose tolerance test in patients at risk for developing T2D and treated with atorvastatin (40 or 80 mg / day).
Fibroblast Growth Factor 23 and Fibroblast Growth Factor 21 are two endocrine Fibroblast Growth Factors, requiring Klotho as a co-factor to promote their systemic actions. Fibroblast Growth Factor 21 is involved in the regulation of glucid and lipid metabolism. Fibroblast Growth Factor 21 Knock Out mice display obesity and hyperglycemia. In investigators experience, patients with X-linked hypophosphatemia often present with early-onset over-weight that could be partly explained by decreased physical activity because of bone pains and deformations after puberty; however, patients usually display progressive over-weight earlier in life, when there is no limitation of physical activity yet. To the knowledge of investigators the association between Fibroblast Growth Factor 23, Fibroblast Growth Factor 21 and Klotho in patients with X-linked hypophosphatemia has never been evaluated. Thus, the main objective of this study is to evaluate the glucid and lipid metabolism in patients with X-linked hypophosphatemia, the main working hypothesis being that the genetic deregulation in the Fibroblast Growth Factor 23 axis in patients with X-linked hypophosphatemia induces modifications of Klotho levels (namely decreased levels) that in turn will deregulate the Fibroblast Growth Factor 21 axis (resistance to Fibroblast Growth Factor 21 because of decreased Klotho levels).
Angular measurement of deviation is an essential element in the clinical evaluation of strabic patients. It is performed by orthoptic methods. However, studies show that the same patient presents a great variability of his angular measurement between 2 consultations, and between 2 observers. Automated angle measurement is a recent concept that aims to overcome the defects of subjective angle measurement by alternate occlusion test and prismatic bar. Improvements made by these devices would provide reliable, objective and reproducible measurements of the angle of deviation by increasing the accuracy of strabal angle assessment, improving decision making and surgical follow-up, decreasing inter-examiner variability and variability over time, and facilitating data comparison to improve scientific publication possibilities. The Gazelab® device is a video-oculograph combined with a laser projection system and an infrared camera. It allows an objective angular evaluation, in non-dissociating physiological conditions, possible even in the absence of binocular vision and allows an analysis of the deviation in all positions. There is extremely little data in the literature on automated measuring devices. The Gazelab tool is still little known in the strabology discipline and seems to have a number of advantages over other devices. The interest of this examination towards this pathology led the ophthalmology department to use it in the current practice, and since recently it is an act nomenclaturé.
Purulent meningitis are life-threatening diseases in childhood. Cerebral vasculitis have been described in bacterial meningitis, but poor is known about their physiology and their impact on outcome. The investigators decide to realize a retrospective mono-centric study carried out at Montpellier university hospital which looks back at a 7-year study(2009-2016). The Investigators selected purulent meningitis cases based on the bacteriological data provided by the HDB (hospital data base). The Investigators divides in two groups : Group A if patients present a cerebral vasculitis ( radiologic diagnostic by RMI or tomodensitometry), in all, cases the diagnosis of vasculitis was confirmed by a radiologist specialised in neuropaediatrics by a second reading;Group B purulent meningitis with a cerebral vasculitis imaging. Tuberculous meningitis, meningitis in CSF shunt, and in patients having chemotherapy were excluded. The investigators report clinical and biological finding, inflammatory marker at the onset. The Investigators register also the clinical evolution and sequelae
Summit is developing ridinilazole as a novel antimicrobial for Clostridioides difficile Infection (CDI), formerly known as Clostridium difficile Infection, with the goal of demonstrating an improved Sustained Clinical Response rate in subjects treated with ridinilazole as compared to subjects with vancomycin. A phase 2 proof of concept study, with vancomycin as comparator, demonstrated these attributes with a comparable safety profile. A high fecal concentration of ridinilazole and little systemic exposure were noted. The rationale for this phase 3 study is to confirm the improvement in sustained clinical response of CDI over vancomycin and to compare the safety and tolerability of ridinilazole to that of vancomycin.
The study design is a prospective, multicenter, single-arm, global IDE study to evaluate the safety and effectiveness of the Shockwave Medical Coronary Intravascular Lithotripsy (IVL) System in de novo, calcified, stenotic coronary arteries prior to stenting. Disrupt CAD III is being conducted as a staged pivotal study.
Sleep disorder is often a complaint from the older people. Prevalence of sleep disorder increases with aging and reaches between 20 to 45% of the people of 65 years old and more. Sleep physiologically changes with aging. Sleep can also be disturbed by other factors such as intercurrent or related chronic pathologies, environmental change (institutionalized, death of a spouse…), or some medical treatments. Regardless of interindividual variabilities, normative criteria have been defined by a meta-analysis: insomnia can be diagnosed if night wakings are more than 60min and/or if sleep latency is more than 30 minutes. Various studies have proved the major role of sleep on health and wellbeing. Sleep disorders have an impact on the quality of perception of health and on the quality of life of people and their spouse. According to the French High Health Authority recommendations, sleep diary and validated scales are the tools to use to investigate sleep disorders. Results from previous studies brought us to consider sleep complaint more specifically and adjust to the heterogeneous population of the investigator's hospital with a subjective approach. This work intends to offer a program of individualized advice to older patients with no cognitive impairment, or with a mild or moderate cognitive impairment, who complain about their sleep quality. Patients with a moderate cognitive impairment who have a caregiver at home can also join the study. The main objective of the study is to evaluate the impact of individualized care for sleep disorders on quality of sleep using the Pittsburgh Sleep Quality Index which validity was demonstrated among the elderly.
The objective of this study is to investigate whether the cocktail of natural antioxidants XXS-2A-BR2 comprising vitamin E and coupled with omega-3 helps to prevent and / or reduce the deleterious effects induced by long term physical inactivity through antiorthostatic bedrest. During a randomized 60 day bed rest study in 20 healthy male adults the two following aims will be undertaken: - Sixteen scientific protocols will assess the changes in the cardiovascular, metabolism, muscle, bone, neuro sensorial, hematological and immunology systems. - In the above mentioned systems, the potential beneficial effects of the countermeasure protocol will also be investigated.
Since decades, literature has shown that smoking has negative effect on postoperative outcome. Recent systematic review and meta-analysis on clinical impact of smoking and smoking cessation showed that postoperative healing complications occur more often in smokers compared with nonsmokers. The use of electronic cigarette (e-cigarette) is spreading through the world. Despite this fact, the health risk assessment studies on e-cigarette are limited and scientific evidences are inconsistent. This prospective multicenter study aimed at assessing the use of e-cigarette whether patient undergoing elective surgery. The main objective of this study was to evaluate the prevalence of e-cigarette consumer in perioperative period. Secondary objectives were to analyze when patients consume e-cigarette in regard of surgery, how many dose they consume and if they also consume nicotine cigarette.
