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.
Project rationale: Since 2017, multiple sclerosis diagnosis should match the new McDonald criteria in which a "no better explanation than MS" should be fulfilled. However, many patients present with red flags that lead to a complex diagnostic work-up. There are no available biomarkers that permit to confirm or roll out MS diagnosis in such cases. Therefore, we lack biological markers that can help in the diagnosis of patients presenting with suspected MS. Many studies have found that serum and cerebrospinal fluid (CSF) cytokines could help to differentiate MS from other diseases such as neuromyelitis optica spectrum disorders (i.e., IL-6) or neurosarcoidosis (i.e., sIL-2R). Serum and CSF kappa free light chains have also shown good diagnosis performance in MS. In daily practice, our MS tertiary center already perform the analysis of CSF concentrations of IL-1β, sIL-2R, IL-6, IL-10, and serum and CSF kappa and lambda free light chains to roll out other central nervous system (CNS) autoimmune diseases in patients presenting with white matter hyperintensities (WMH). Objective: To correlate CSF IL-1β, sIL-2R, IL-6, IL-10, serum and CSF kappa and lambda free light chains with the final diagnosis in patients presenting to our MS tertiary center with suspected MS to identify a specific inflammatory biomarker profil involved in MS and other CNS autoimmune diseases. The methodology: This is an observational study. All patients ongoing a routine diagnostic work-up for suspected MS from june 2020 to june 2022 in our MS tertiary center will be analyzed. Cerebrospinal fluid IL-1β, sIL-2R, IL-6, IL-10, serum and CSF kappa and lambda free light chains will be correlated with the final diagnosis to ultimately find MS associated biomarkers.
nasosinus polyposis (=PNS) is a chronic inflammatory disease of the nasal cavity and sinus cavity with a prevalence of 2 to 4% in the general population. The functional impact of PNS has a major impact on one's quality of life.Medical treatment, nasal irrigations and local glucocorticoids as well as short treatment of oral glucocorticoids have shown a short-term benefit versus placebo. Surgery improves the efficacy of local treatments, but 40% of patients have a recurrence of polyps at 18 months and 20% of patients require a surgery recovery at 5 years. The development of monoclonal antibodies directly targeting the inflammatory way is a real public health issue. Bachert C. et al recently demonstrated the efficacy of Dupilumab (anti-IL-4/13 antibody) injected subcutaneously on the overall symptomatology of PNS. The marketing authorization (AMM) for the first biotherapy to be available soon includes PNS's severe nature and resistance to treatment, although there is no consensus definition or score to characterize this severity. This study aims at developping a score for assessing severity in PNS. We suggest that this assessment strategy could be applied to the PNS. The originality and the innovative character of this project is the statistical modeling behind the creation of the score. Thus, the importance of symptoms, anatomical and biological factors, the estimation of the quality of life of the patients, the level of care use and the number of surgeries all become measurable indicators that are a direct reflexion of the severity and the control of PNS, called latent variables because they cannot be directly measured. To consider this detail, modeling using structural equations seems optimal to develop a severity score (PSI score) of PNS in order to personalize the therapeutic care of patients. Main Objective: To develop a severity score for PNS using latent variable modeling: Polyps Severity Index (PSI)
Pre-eclampsia (PE) is a pregnancy-associated syndrome of variable severity, classically defined by the combination of hypertension and proteinuria in a previously non-hypertensive or proteinuric patient. These symptoms normally resolve within 2-3 months after delivery regardless of the severity of the pre-eclampsia. Regardless of its definition, preeclampsia is associated with an increased risk of obstetric events and, for the mother, an increased risk of developing chronic kidney disease (CKD), hypertension, diabetes and cardiovascular disease in the broad sense. The relationship between preeclampsia and Chronic Kidney Disease is, however, complex and not fully understood. Investigator proposes an interventional study to identify the diagnosis of Chronic Kidney Disease in patients who have developed an episode of Preeclampsia.
To describe the causes mentioned by general practitioners, explaining the under-treatment of the three main treatments for heart failure with impaired ejection fraction (ARS blockers of the type ACEinhibitor/ARA2/ARNi, ß- and/or anti-aldosterone).
The diagnosis of breast cancer and the treatments implemented have a significant impact on the professional situation. Maintaining employment and/or reintegration into working life are therefore major issues for cancer patients. This trial proposes to study the feasibility of a support/coaching program for a return to work in patients after breast cancer.
Acute respiratory distress syndrome (ARDS) accounts for almost 10% of intensive care units (ICU) admissions. Three ARDS stages have been defined, based on the PaO2/FIO2 ratio measured with positive end-expiratory pressure (PEEP) ≥5 cmH2O: mild (201-300 mmHg), moderate (200-101 mmHg), and severe (≤100mmHg). They represent 30.0%, 46.6%, and 23.4% of ARDS, respectively. Mechanical invasive ventilation (MV), the cornerstone of ARDS patient care, has a primary goal to protect the lung from ventilator-induced lung injury (VILI). Delivering MV in a prone position (PP) has been shown to improve oxygenation, protect the lung through a better homogenization of lung stress/strain, and stabilize hemodynamics. A meta-analysis of four randomized controlled trials showed beneficial effect of PP vs. supine position (SP) in the most hypoxemic patients. A fifth randomized controlled trial further showed a significant reduction in mortality with PP in ARDS patients with PaO2/FIO2 <150 mmHg, when neuromuscular blockade and long prone positioning sessions were used. Therefore, PP has since been strongly recommended for ARDS patients with PaO2/FIO2 <150 mmHg. Yet, there is limited evidence in patients with mild to moderate ARDS. There are, however, strong arguments supporting the need for a new trial in ARDS patients with PaO2/FIO2 in the range 150-300 mmHg: 1. There is no trial that has specifically tested PP in this ARDS subset; 2. PP is safe and has become a standard of care in ICU; 3. Should VILI prevention be a mechanism through which PP improves survival, this should be involved in all ARDS patients; 4. The mortality at hospital discharge in this subset of ARDS remains significant, amounting to 34.9% (95% confidence intervals 31.4-38.5%) in mild and 40.3% (37.4-43.3) in moderate stages; 5. Among 580 patients with mild ARDS at admission to the ICU, in-hospital mortality was 10%, 30%, and 37% for those who improved, persisted, and worsened ARDS, respectively. 6. Finally, PP has been shown to be cost-effective under commonly accepted thresholds. The hypothesis is that in patients within the 150-300mmHg PaO2/FIO2 range at the time of ARDS diagnosis, PP can reduce mortality as compared to a similar group left in the SP.
Adult-Onset Still's disease is a polygenic autoinflammatory disease of unknown etiology. The autoinflammatory character individualizes it from autoimmune autoantibody diseases. Clinically, it results in the classic triad associating hectic fever, evanescent rash and arthritis. Although it is benign in the vast majority of cases, life-threatening complications can occur. By definition, the disease affects adults over 16 years of age, however most experts now agree that the adult form and the pediatric form belong to a pathological continuum: Still's disease. In the absence of a specific biomarker, the diagnosis is still based on clinical and biological criteria, after the exclusion of differential diagnoses. Classically, three evolutionary profiles of Adult-Onset Still's disease are individualized, depending on the evolution of symptoms over time: - a monocyclic systemic form (30% of cases) characterized by clear systemic symptoms and in the foreground compared to the articular signs. This form evolves over several weeks to several months (on average 9 months), without exceeding a year. By definition, there is no recurrence; - a polycyclic systemic form (30% of cases) defined by the occurrence of at least two systemic or joint episodes, separated by clinical remission intervals greater than two months, or even several years. The symptoms of relapses are not always the same as the initial symptoms. The number and severity of relapses is unpredictable and varies widely from patient to patient, but symptoms tend to become less severe over time. - a chronic form, with predominant joint involvement (40%), resembling seronegative rheumatoid arthritis. Systemic signs are present during the first outbreaks of the disease. Subsequently, rheumatoid arthritis evolves on its own and one can see joint destruction or conversely ankylosing developments such as the classic bilateral, non-erosive fusing carpitis. There are reasons to believe that the evolving profile of patients has changed since the emergence and generalization of biotherapies. Furthermore, no prognostic factor for the progression of Adult-Onset Still's disease has been found so far. The differences between pediatric and adult forms need to be confirmed and becoming pediatric forms in adulthood is poorly described. The objective of this study is to set up a regional research database (Auvergne-Rhône-Alpes-Limousin) in order to describe the characteristics, treatment and evolution of patients with Still's disease.
The PROTECT trial will test the hypothesis that proton (PT) -enabled radiation dose reductions to sensitive, normal tissues will result in lower rates of treatment-related pulmonary complications in esophageal cancer compared to standard photon therapy (XT).
The pandemic caused by COVID 19 continues to pose a threat to public health worldwide. Currently, approximately 2,397,312 people have died from it and 108,715,375 confirmed cases have been reported, according to the World Health Organization (WHO) as of February 13, 2021. Patients with chronic kidney disease (CKD) are, from stage 3, at risk for a severe form of COVID 19 and this risk increases with the severity of the disease, including in dialysis or transplant patients according to the press release. HAS of December 2020. As a result, France has prioritized vaccination for these patients the mRNA vaccine Therefore, the objective of this work is to study the safety of the vaccine in a population of hemodialysis patients in a heavy center, and the efficacy on the immune response (IgG) and the kinetics induced after 3 doses of the anti-Covid vaccine. to RNA.
Multidrug Resistant (MDR) bacteria have become a major worldwide public health challenge and hospitals are now increasingly faced with management of local outbreaks involving such pathogens. Especially, intensive care units (ICU) provide an ideal background for outbreaks caused by MDR bacteria among which carbapenemase-producing Enterobacteriaceae (CPE) can be found. Among CPE involved in ICU outbreaks, VIM producers have been reported worldwide, and described as especially difficult to control. The COVID-19 pandemic and all of the measures health workers have to implement to fight the spread of SARS-Cov-2 have also impacted the management of such outbreaks. In this retrospective study, the investigators aim to describe the management of an outbreak caused by a VIM-producing Enterobacter cloacae strain during the 2020 COVID-19 pandemic in an ICU, and show the importance of concerted measures and actions implemented at multiple levels to prevent the spread of this MDR strain.
