Filter by:The goal of this clinical trial is to investigate the therapeutic efficacy of rapidly correcting vitamin D deficiency in adults with the use of 25-hydroxyvitamin D3 [25(OH)D3] for reducing the risk of acquiring the SARS-CoV-2 (COVID-19) viral infection and mitigating morbidity and mortality associated with this infection. This evidence-based hypothesis is related to several observations. Macrophages, activated T and B lymphocytes have a vitamin D receptor and 1,25-dihydroxyvitamin D3 induces defensin protein synthesis, influences immunoglobulin production and modulates T-cell cytokine production and functions. 1,25-dihydroxyvitamin D3 also reduces the angiotensin-converting enzyme 2 (ACE2) that is believed to serve as the binding site and gateway for COVID-19 to become infectious. This is a multicenter randomized3 doubleblinded placebo-controlled study aimed at determining the benefits of 25(OH)D3 treatment for the prevention of COVID-19 infection and improving clinical outcomes in infected patients. The investigators plan to recruit 1500 subjects in 3 study groups that include hospital health providers, patients with a positive test for COVID-19 and their relatives with a negative test. Eligible subjects in each study group with a documented serum level of 25(OH)D < 20 ng/mL will be randomized. Recruited subjects will be given 25 mcg of 25(OH)D3 daily or an identically appearing placebo at the time of randomization for two months. Three hospitals will participate and the sample size is foreseen to be equally distributed between the three. Since the clinical trial is designed as minimal risk a formal committee for data monitoring is not foreseen. However, potential toxicity will be monitored every 4 weeks with a serum calcium, albumin and creatinine by the PI and the study coordinators. If the corrected serum calcium increases above 10.6 mg/dl and a repeat confirms that the calcium is above 10.6 mg/dL the subject will be dropped from the study and referred to his or her PCP. Early signs and symptoms of vitamin D toxicity associated with hypercalcemia are increased thirst, increase in frequency of urination, especially at night. The subjects will be followed up weekly by phone to ask about their sign and symptoms.
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.
Coronavirus disease 2019 (COVID-19) is a disease caused by a novel coronavirus called SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2). The most characteristic symptom of patients with COVID-19 is respiratory distress, leading to inability to sustain spontaneous breathing. In addition, patients with COVID-19 have dyspnea and respiratory muscle fatigue. Therefore, it is necessary to use strategies that minimize the impact of COVID-19 on the respiratory muscles, accelerating the ventilatory weaning process and optimizing the functional capacity of the involved muscles. Over the past years, evidence has shown the effectivity of photobiomodulation therapy (PBMT) combined with static magnetic field (sMF) (PBMT/sMF) in delaying muscle fatigue, decrease in markers of inflammatory damage and oxidative stress of skeletal muscle. These effects result in an improvement in the functional capacity of the irradiated muscles by PBMT/sMF. However, do date, there is a lack of evidence regarding the effects of PBMT/sMF on the respiratory muscles. Therefore, the irradiation of PBMT/sMF may result in improvement in the functional capacity of respiratory muscles in patients with COVID-19, accelerating the ventilatory weaning process of the patients intubated due to respiratory failure. In addition, the irradiation of PBMT/sMF may induce the increase of anti-inflammatory mediators' activity in patients with COVID-19. Thus, the aim of this project is to investigate the effects of PBMT/sMF on respiratory muscles of patients admitted to the Intensive Care Unit (ICU) with COVID-19 using invasive mechanical ventilation.
A randomised controlled trial designed to test whether an online expressive writing intervention (LIO-C) can reduce distress for English-speaking adults during the global COVID19 pandemic. Hypothesis: LIO-C will improve distress (as measured by K10) in adults at 1 week post-intervention compared to a neutral writing control during the COVID19 pandemic.
This is a Phase II, randomized, double-blind, placebo-controlled, multicenter study to assess the efficacy and safety of MSTT1041A (astegolimab) compared with placebo and of UTTR1147A compared with placebo, in combination with standard of care (SOC), in patients hospitalized with severe coronavirus disease 2019 (COVID-19) pneumonia.
The authors hypothesize that the SARS-CoV-2 virus can affect the kidneys, causing them to be damaged. The present study aims to explain the mechanisms of kidney injury in patients diagnosed with COVID-19.
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.

Introduction There are currently no treatments with demonstrated efficacy for COVID-19 infection. Epidemiological evidence points to the existence of intrinsic protection factors which make young persons and women more resistant to the infection, whereas older patients with multiple illnesses, above all with heart disease, are at greatest risk. This trial proposes treatment initiated in the early stages of the disease, when clinical worsening is most likely, with intravenous Oxytocin (OT), an endogenous hormone currently safely used in clinical practice. The selection of this molecule is based on numerous experimental and clinical observations, which show its activity in modulating resistance to pathogens, in mitigating overall cardiovascular risk, and in acting on the production of Nitric Oxide (ON) in the lungs, which is emerging as a key therapeutic factor for the improvement of respiratory function in patients with SARS-COVID 19. Finally, OT is physiologically produced by the human body, especially in the female sex and in the age ranges that coincide with most resistant patients. In routine clinical practice, OT exhibits an excellent therapeutic index, in absence of significant adverse effects. Primary aim To assess the effects of Oxytocin in addition to standard therapy, with respect to Standard of Care (SoC), in reducing the number of patients who enter a critical stage Secondary aim To describe: - Mortality 28 days after randomization - Time to mechanical ventilation during the study - Duration of dependency on oxygen supply - Length of stay - Temporal trend of clinical improvement (7-category ordinal scale) - Safety analysis
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.
