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.
Wilson's disease is a rare genetic disease, affecting less than 1,500 people in France. The transmission is autosomal recessive linked to an anomaly of the ATP7B gene on chromosome.This gene codes for an ATPase-type transmembrane protein involved in the transport of copper through the cell plasma member.This gene codes for an ATPase-type transmembrane protein involved in the transport of copper through the cell plasma member. If there is no mutation, this ATPase incorporates copper into apo-ceruloplasmin to be released into the blood serum. The mutation of the ATP7B gene results in a defective biliary excretion of copper, leading to its accumulation in the liver, but also in other organs such as the eye or the brain. Advances in treatment have dramatically changed the prognosis for Wilson's disease, making the desire for pregnancy more confident. The consensus is to maintain treatment during pregnancy, reducing the dosage to limit teratogenicity as well as the risk of fetal copper deficiency.The mammary gland is the primary site of copper metabolism in lactation, and ATPase 7B is the primary effector. It has been shown in a mouse model of Wilson's disease (ATP7B - / - mouse) with treatment, that mothers accumulate copper in the liver but also in the mammary gland. However, a recent study showed that the copper level in breast milk was normal in 18 Wilsonian patients treated with D-penicillamine, trientine salts or zinc salts, suggesting that breastfeeding is possible in these patients without risk to the development of the infants.The problem of breastfeeding newborns for patients with Wilson's disease is therefore associated with a risk of copper deficiency in the newborn due to insufficiently rich breast milk in copper due to drugs. In addition, the passage into breast milk of treatments is not sufficiently known. These factors make breastfeeding not currently recommended for Wilsonian mothers,However, many patients wish to breastfeed and some of them breastfeed their newborns despite the risk of breastfeeding
A study to evaluate if the randomized addition of venetoclax to a chemotherapy backbone (fludarabine/cytarabine/gemtuzumab ozogamicin [GO]) improves survival of children/adolescents/young adults with acute myeloid leukemia (AML) in 1st relapse who are unable to receive additional anthracyclines, or in 2nd relapse.
Evaluate the sensitivity of the GERONTOPOLE scale, used by general practitioners in primary care outpatients for the diagnosis of frailty in non-dependent people more than 65 years old, using as reference the "évaluation gériatrique standardisée clinique" (EGS)
Sacrococcygeal teratomas are the most common neonatal tumors and require rapid and complete resection. Tumor nerve compression and pelvic surgical sequelae may lead to many and varied voiding disorders. Data concerning long-term vesico-sphincteric disorders are conflicting. Some studies find good functional results [Cozzi et al., 2008; Draper et al., 2009]. However other authors reveal neurologic bladder with detrusor sphincter dyssynergia [Hambraeus et al., 2018] and rise concerned about long-term renal function [Khanna et al., 2019; Rehfuss et al., 2020] even in the absence of clinical voiding disorders. Most of studies include young patients with other malformations such as anorectal malformations or dysraphisms which may impact the results. The main objective is to assess bladder dysfunction in children aged 6 to 18 years after isolated sacrococcygeal teratoma resection.
Several elements suggest that suicidal vulnerability may be associated with an alteration in the perception of affective touch. On the one hand, anhedonia, characterized by a decrease in the pleasure felt, is strongly associated with suicidal ideation, independently of depression. However, the ability to feel pleasure is essential in the perception of affective touch. On the other hand, suicidal behaviors are associated with interpersonal difficulties, of which communication is an integral part, and communication is partly through touch. The investigators therefore wish to explore the perception of affective touch in suicidal behavior by using an affective tactile stimulation in 72 subjects with and without a history of suicide attempts (SA).
COVID-19 associated mortality remains high despite the advances in therapeutics such as dexamethasone. The severity of COVID-19 results from direct viral cytotoxicity, and the inflammatory response, which is associated with a hypercoagulable state, contribute to lethal hypoxemic pneumonia. During the SARS-CoV-2 replication phase, infected cells secrete chemokines and die by activating the immune system locally. A local inflammatory loop induces tissue destruction, which activates the immune system's circulating cells, leading to another amplifying loop called the cytokine storm. In these phenomena, the integrity of the interferon pathway plays a significant role. Specific impairment of the interferon pathway has been identified in a subset of patients and is associated with high Covid-19 severity. This subset of patients presents preexisting autoimmune disease mediated by autoantibodies directed against IFN. It represents 10.2% (101/987) of patients admitted in ICU with COVID-19 pneumonia, and the observed mortality in this subgroup is 40%. The investigators hypothesized that plasma exchanges (PE) would eliminate these autoantibodies while acting on other mechanisms of the pathogenesis of severe COVID-19, such as cytokine storm or hypercoagulability(7). The EPIC trial aims to demonstrate the efficacy of plasma exchange in the subpopulation of patients with anti-interferon autoantibodies and severe COVID-19 hospitalized in intensive care and on oxygen therapy, high flow or not, receiving non-ventilation or invasive ventilation, on D28 survival.
The discovery of congenital malformations and/or non-specific signs by ultrasound (5% of pregnancies) represents a real medical challenge. Their prognosis is variable depending on the underlying etiology, ranging from acquired fetopathies to rare genetic diseases. In France, the diagnostic approach is currently based on imaging examinations (ultrasound, brain MRI, 3D bone scans, etc.) and/or biological examinations, generally on invasive sampling (trophoblast biopsy, amniocentesis or fetal blood puncture) with infectious (CMV, toxoplasmosis, parvovirus B19, etc.), metabolic (enzymes in the bloodstream, etc.), and genetic (standard karyotype, FISH, array CGH and targeted gene sequencing) investigations. The yield of this strategy is about 30%, leaving 70% of couples without a possible prognosis. Over the last decade, medical genetics has undergone a technological revolution with the development of high-throughput DNA sequencing (HTS) allowing the analysis of targeted genes (panel) or the exome (ES). International studies published on the use of ES in prenatal diagnosis (PND) have become more common, with variable inclusion criteria, resulting in diagnostic rates between 15 and 36%, higher than those of array CGH (8-15%). In France, FHU TRANSLAD coordinates the national pilot study AnDDI-PRENATOME, which has made it possible to remove the technological barriers for PND ES and to obtain a diagnostic yield of 39% in 33 days on average. In parallel, the recent development of NIPD (Non-invasive prenatal screening) on free fetal DNA circulating in maternal blood has made it possible to propose a non-invasive strategy. However, this technique is currently used in prenatal care only in a few indications: determination of the fetal sex, search for aneuploidies, analysis of the fetal rhesus status or, more rarely, the targeted diagnosis of monogenic diseases. The team in Strasbourg has recently conducted a pilot study using an NIPD-panel in couples with a history of neomutation in a gene responsible for intellectual disability, which has demonstrated the feasibility of capturing and then sequencing a panel of 500 genes on free fetal DNA circulating in maternal blood. As high-depth exome sequencing from small amounts of DNA is now affordable and feasible, the investigators wish to compare invasive and non-invasive approaches for the discovery of fetal malformations on ultrasound: a trio exome analysis will be performed in parallel to circulating fetal DNA and fetal DNA extracted after an invasive puncture in order to compare the diagnostic performance of these two approaches. The investigators propose a pilot study in order to prepare an organizational evaluation including an evaluation of the stakes for coordination and interactions between professionals, the relevance of the system (acceptability, expectations, satisfaction of couples and professionals...), its effectiveness and efficiency. The aim of this pilot project will be to observe the organizational impact on the Plurldisciplinary Centers for Prenatal Disagnostics and the genetic laboratories, and to refine the indicators necessary for monitoring the system; it will also involve conducting exploratory interviews with professionals and couples in order to prepare the qualitative study that will subsequently make it possible to evaluate the relevance of the organization.
Phase II trial with three independent strata to independently assess the effects of the association of pembrolizumab and cabozantinib in advanced sarcomas.
"Sarcoidosis is a systemic granulomatous disease of unknown cause(s).Determining disease activity is a major element in the treatment decision. 1H- Nuclear magnetic resonance (NMR) spectroscopy allows the identification of biomarkers in different pathologies and in particular in a pilot study of saliva of patients with sarcoidosis. Applications to sarcoidosis are still rare, having concerned only serum and saliva. In this context we hypothesize the existence of a difference in the metabolic products found in the urine of sarcoidosis patients with different degrees of activity and/or disease severity. We designed an analysis of urinary metabolomics in sarcoidosis patient using NMR spectroscopy with multivariate statistical analysis, followed by metabolite identification and pathway analysis. "
Nearly half of critically ill children are intubated and enterally fed according to recent guidelines. However, no evidence-based recommendation are available regarding fasting times prior to extubation. When an extubation is planned, children do not always present with normal neurological status yet, and are at risk of vomiting and aspiration. Extubation may also fail and require re-intubation with similar risks. Thus, pre-operative fasting guidelines are often transposed to the paediatric critical care setting, aiming for an empty stomach at extubation, with perceived decreased risks of aspiration. However, the gastric and gut motility pathophysiology is significantly different in critically ill children (frequent gastroparesis, liquid continuous feeding, etc.) compared to planned surgery children. The extrapolation of practice validated in the latter population may be inadequate. The stomach may be empty more or less rapidly than expected, leading to unnecessary prolonged fasting times or inappropriately short fasting times respectively. Gastric ultrasounding monitoring may help assessing gastric content prior to extubation. Investigators hypothesise gastric content clearance may be different in critically ill children prior to extubation, compared to pre-operative paediatric guidelines for elective surgery.
