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.
Maternal-fetal transmission in the second or third trimester of pregnancy of the SARS-COV-2 virus could explain some late fetal losses. Finding a cause in the context of fetal loss is essential for parents and caregivers. It helps to understand the history of the disease, to address the possible risk of a recurrence and to plan for future pregnancies. If the maternal-fetal transmission of COVID 19 is confirmed and that it is responsible for obstetric complications, a preventive action could be proposed to the patients by the preconception vaccination. The investigators are seeking to clarify the frequency of this transmission is information awaited by caregivers, women, couples in particular when the latter are in distress from late fetal loss.
Introduction: The SARS-Cov-2 outbreak in France and the concomitant massive increase in the number of cases requiring hospital management create a major risk of COVID-19 infection for hospital staff. In addition to nosocomial transmission, the health care workers (HCWs), defined as persons serving in health care settings who have the potential for direct or indirect exposure to patients or infectious materials, are also exposed to community transmission. Whether HCWs acquire infection at work or in the community is important to adapt protection measures. A few studies investigated COVID-19 infection among medical and nursing personnel. However, none have analyzed all categories of hospital staff. As of April 9, 2020, a total of 9,282 US HCWs with confirmed COVID-19 had been reported to CDC (US), however description of occupational activities was not available. Therefore, limited information is available about COVID-19 infection among HCWs. Thus, the objectives of the sdudy are to estimate the incidence of symptomatic SARS-CoV-2 infection in HCWs in five university hospitals (including geriatric hospitals) of the great Paris area and to estimate both nosocomial and community risk factors. Method: A prospective and retrospective cohort study that includes all hospital staff (including medical and nursing personnel, health care managers, laboratory, radiology, reception staffs, stretcher-bearers, etc.) working in different departments of five university hospitals (acute medical centers and geriatric hospitals) in the great Paris area (9 000 HCWs). Incidence of symptomatic SARS-CoV-2 infection will be estimated with its 95%CI. Individual and contextual risk factors will be analyzed using multilevel multivariate logistic regression modelling to account for clustering and confounding. Conclusion This study should make it possible to better characterize SARS-Cov-2 contamination of HCWs and to estimate the share of nosocomial transmission.
Mechanical ventilation in ARDS requires protective ventilation and PEEP. Airway closer has to be overcome to reduce lung heterogeneity, AOP is measured globally with a ventilator PV curve without PEEP. EIT derived PV curve is another method that could determine heterogeneity of AOP between both lung. This study aims to determine whether AOP measured with EIT derived PV curve is similar to AOP on the ventilator PV curve and see if AOP is different between lungs. If airway closer is higher on one lung, global AOP on the ventilator PV curve probably estimates the other lung.
Since December 2019, the world has faced a pandemic of COVID-19, an infectious disease caused by SARS-CoV-2, a virus that emerged in China. The reference diagnosis is based on the search for the SARS-COV-2 genome in the nasopharyngeal sample. Carrying out this sample requires the competence of a healthcare professional and presents some inconveniences for the tested patient. Because saliva collection is simple, non-invasive, painless and inexpensive, and can be performed by poorly trained personnel, it could be an alternative to the reference nasopharyngeal sample. SARS-CoV2 detection in human saliva could be a potential diagnosis of COVID infection.
The main objective of this retrospective clinical epidemiology study is to describe the characteristics of Covid-19 cases requiring hospitalization in adult patients with lymphomas during the initial phase of the epidemic (from 01/03/20 to 30/04/20). The specific objectives are to estimate the frequency of severe forms of Covid-19 and those requiring intensive care hospitalisation, as well as the mortality related to the epidemic among the active file of patients followed for lymphoma at each study site, to investigate whether certain chemotherapy and/or immunotherapy treatments seem to be associated with severe forms or prolonged evolutions of Covid-19, to describe possible atypical clinical forms among the population of patients treated for lymphoma.

SARS-CoV-2 outbreak causes a spectrum of clinical patterns that varies from asymptomatic infection to mildly symptomatic manifestations and more-severe forms that need intensive care. Until now, the immune response to SARS-CoV-2 virus infection has been poorly reported to help decision for immune modulation therapies. As a consequence, trials have been designed to test both anti-inflammatory molecules as steroids or anti-bodies against IL-6, and others proposing to "boost" immunity with interferon beta based on similar inclusion criteria. The immune response to infective agents including viruses may have a complex time evolution with early and late phases corresponding to different patterns, oscillating between pro-inflammation and immune-depression. The potential window to improve outcome in COVID-19 by therapeutic intervention aimed at a fine tuning between immune toxicity and immunodepression requires a longitudinal assessment during the course of illness, especially for the patients who develop acute respiratory failure. Immune monitoring of both innate and adaptive immunity would then be essential to appropriately design clinical trials. The whole blood cells evaluation was recorded according to the time intervals between the onset of symptoms and the sampling after ICU admission. Patients' care was standardized, especially with regard to ventilation, sedation, and antimicrobial treatment. In this study the investigators prospectively perform a longitudinal study of both innate and adaptive immunity on patients admitted to ICU for an COVID-19 related acute respiratory failure. The data will be analyzed in reference to the onset of initial symptoms and also to the admission in ICU. The primary end point is the evolution of the characterization of monocytes and their subsets in term of number and expression of HLA-DR. A similar approach is used for lymphocytes and their subtypes with in addition, an ex vivo testing of their capabilities to be stimulated by SARS-CoV-2 viral proteins in term of TNFalpha, INFgamma, and IL1beta production. The secondary end-point was to test the association with outcomes and other non-specific markers of inflammation as CRP (C reactive protein), PCT (procalcitonin), DDimers and ferritin.
The 2020 pandemic of the coronavirus (SARS-CoV2) has lead to an increase in ARDS cases requiring invasive mechanical ventilation in the ICU (Intensive Care Unit). The investigators hypothesize that airway pressure release ventilation (APRV) could be beneficial in patients with ARDS secondary to SARS-COV2 viral pneumonia.
Nasal High Flow oxygen therapy (NHF) is commonly used as first line ventilatory support in patients with acute hypoxemic respiratory failure (AHRF). It's use has been initially limited in Covid-19 patients presenting with AHRF. The aim of the study is to describe the use of NHF in Covid-19-related AHRF and report the changes in the respiratory-oxygenation index (termed ROX index) over time in these patients.
The management of patients with SARS-CoV2 in respiratory distress can expose to corneal or retinal lesions induced by the stay in intensive care. Examination by ophthalmologists would make it possible to detect the most of the ophthalmologic problems known in intensive care and to provide an early, preventive or curative therapeutic response when possible, in order to avoid irreversible visual loss. The object of the research is to assess the presence and the importance of surface ophthalmologic lesions, the presence and the importance of retinal or optic nerve lesions, in order to improve the monitoring and primary prevention of this population
