Filter by:The initial symptoms described in the first cases of COVID-19 were mainly fever and respiratory signs. Recently, there has been an increase in cases of hyposmia without associated nasal obstruction or rhinorrhea. Although we do not yet know the long-term consequences of COVID-19 on olfaction, there is evidence in the literature demonstrating that post-viral hyposmias are an important source of long-term olfactory disorders, impacting quality of life. Usually, the treatment of viral hyposmias is based on local and/or general corticosteroid treatment combined with saline nasal irrigation at the onset of signs. Because of the possible development of severe forms of the SARS-Cov-2 infection, the French Society of Otorhinolaryngology has advised against treatment by corticosteroid therapy and nasal irrigation. However, as the virus is present in the nasal fossae on average for 20 days, persistent hyposmia at 30 days would probably result from an inflammatory or neurological damage to the nasal slits or olfactory bulb. Local treatment with corticosteroids could then be instituted from 30 days after the onset of symptoms of COVID-19 without risk of dissemination. In persistent hyposmia other than chronic rhinosinusitis, the only treatment that has proven its efficacy is nasal irrigation associated with budesonide and olfactory rehabilitation. However, this drug does not have marketing authorisation in France for this indication.
Observational cohort study aiming at comparing the incidence of ventilator-associated lower respiratory tract infections between COVID-19 patients and two control groups: one with influenza pneumonia and the other with no viral pneumonia.
Early administration of sarilumab in hospitalized patients infected with COVID-19 who have pulmonary infiltrates and are at high risk of unfavorable evolution could decrease/prevent progression to acute respiratory distress syndrome (ARDS) requiring high flow nasal oxygenation (HFNO) or either invasive or non-invasive mechanical ventilation.
The aim is to develop a wearable-based ICU (intensive care unit) prediction algorithm for inpatients contracted with SARS-CoV-2. Inpatients with suspicion of COVID-19 or with confirmed SARS-CoV-2 infection will be included. The participants will be equipped with a smartwatch, which gathers physiological data throughout hospitalisation.
The present Diagnostic Accuracy study aims at experimentally validating the use of a rapid salivary test to detect SARS-CoV-2 infection in both symptomatic and asymptomatic individuals as a preliminary approach to a mass screening program. The study is based on a consecutive recruitment of both patients showing symptoms probably associated with COVID-19 (i.e., cough, dyspnea, fever) and asymptomatic patients with a low risk phenotype. The expected number of recruited individuals is 100. The experimental test is a prototype of salivary test based on the Lateral Flow Immunoassay technique and is able to detect the presence of SARS-CoV-2 in saliva, especially the Spike protein (S). The comparison is represented by the nasopharyngeal swab, the gold standard of COVID-19 diagnosis. Patients will undergo both salivary immunoassay and nasopharyngeal swab, thus the outcome assessors are blinded, since the results of the rRT-PCR analysis require at least 6 hours before being available. The main outcomes are sensibility and specificity of the rapid salivary test, when compared with the gold standard (nasopharyngeal swab).
This is a randomized, double blind, multi-center study to evaluate the effects of tocilizumab compared to placebo on patient outcomes in participants with confirmed SARS-CoV-2 infection and evidence of systemic inflammation. The aim of this study is to test the effect of Tocilizumab on multi-organ dysfunction in a phase 3 randomized controlled trial among hospitalized patients with COVID-19 infection. Specifically, as compared to placebo, we will test whether tocilizumab is associated with a reduction in multi-organ dysfunction among hospitalized COVID-19 adult patients with elevated inflammatory measures. Multi-organ dysfunction will be measured as the incidence of the following composite endpoint (mechanical ventilation, renal replacement therapy, mechanical support, need for inotropes or vasopressors, liver dysfunction (increased bilirubin), and all-cause mortality). We will also assess multiple pre-specified secondary (exploratory) endpoints and safety endpoints. We hypothesize that, as compared to placebo, tocilizumab will reduce transfer to the ICU, need for mechanical ventilation, increase rates of hospital discharge in patients diagnosed with severe COVID-19 infection and evidence of exaggerated inflammatory response.
Plasma therapy using convalescent plasma has been shown to be effective in severe acute respiratory syndrome, Ebola virus infection and in H1N1 influenza. More recently there has been a report of the use of convalescent plasma in the treatment of 5 ventilated COVID-19 patients with the suggestion of expedited recovery as the patients improved 1 week after the transfusion. However, this was not a clinical trial and the patients were on other antiviral medication.; therefore, there is a need to undertake such a trial to see if deploying plasma with SARS-CoV-2 neutralizing antibody has utility in managing patients infected with COVID-19 in respiratory distress. The objective of this pilot study is to compare plasma therapy using convalescent plasma with antibody against SARS-CoV-2 to usual supportive therapy in COVID-19 patients with pneumonia and hypoxia, and to determine if the clinical course is improved. The difference between groups will allow an effect size to be determined for a definitive clinical trial.
This research aims to improve the screening for COVID-19 upon admission to the Montpellier University Hospital for an act under general anesthesia or at high risk of transmission of the virus. Indeed, routine nasal swabs present many false negatives (60 to 70%) and many patients with the coronavirus have little or no symptoms. Performing a chest CT scan can reveal early signs very suggestive of viral pneumoniae due to the new coronavirus without additional risk compared to a simple chest X-ray (no injection of contrast medium, low exposure). The objective is to assess the sensitivity of the diagnosis of COVID-19 by carrying out a nasopharyngeal RT-PCR and a low dose thoracic scanography at the hospital admission of patients scheduled to a procedure under general anesthesia or at risk of aerosolization (surgery, endoscopy, procedures involving risk of interventional radiology) in order to limit the risks of transmission to healthcare professionals or other patients and to rationalize the use of protective equipment. This is an observational research without modification of care in the setting of COVID-19 pandemia. All clinical and biological data will be issued from routine care and medical charts. Routine use of CT scan and nasal swabs is an institutional approved strategy. Serologic tests will be performed as soon as available from serum collection collected after routine blood analysis. All data will be anonymously recorded after information and non-opposition of the patient.
Context: On March 11, the World Health Organization (WHO) announced the current corona virus disease 2019 (COVID-19) outbreak as a pandemic. The first laboratory-confirmed case of COVID-19 in Austria was announced on February 27, 2020. Since then, the incidence of infection follows a gradual increase. Measurements taken by the Austrian government include travel restrictions, closing of national borders, social distancing, a mandatory use of facemasks in public, and closing of stores and restaurants. The underlying aim of those imposed restrictions is to contain the viral transmission and to slow spreading of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Objectives: The aims of this study are to determine i) how many employees in Austrian trauma hospitals and rehabilitation facilities have virus specific IgG and IgM antibodies against SARS-CoV-2, ii) how many are active virus carriers (symptomatic and asymptomatic), iii) how many employees are in their incubation period during the study period, and iv) to calculate the SARS-CoV-2 prevalence together with a specific occupation associated infection risk within the different specifications of health care workers. Study Design: Open uncontrolled observational cross-sectional study. Setting/Participants: A total of 4000 employees in 11 Austrian trauma hospitals and rehabilitation facilities of the Austrian Social Insurance for Occupational Risks (AUVA) will be invited to participate in the study. Study Interventions and Measures: An antibody test for SARS-CoV-2 specific IgG and IgM antibodies, and a RT-PCR test based on oropharyngeal swab samples, as well as laboratory-based antibody tests using ELISA, will be implemented to ensure protection and preservation of health in hospital staff and are not part of the study. The tests will be conducted twice, with approximately two weeks in between testing. The results of the tests will be used for statistical analysis in this study together with a questionnaire including questions related to personal health, traveling activities, living situation, as well as inquiries of symptoms and comorbidities.
ACEI-COVID-19 is a multicenter, randomized trial testing the hypothesis that stopping/replacing chronic treatment with ACE-inhibitors (ACEI) or angiotensin receptor blockers (ARB) improves outcomes in symptomatic SARS-CoV2-infected patients
