Filter by:Retrospective multi-center cohort study. Consecutive patients hospitalized for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) up to October 2020 will be included. Patients are followed until discharge from hospital or death.
A coronavirus pandemic began on 12/31/2019 with a first Chinese patient. As of 04/04/2020, the epidemic affects more than 190 countries with more than 50 million official contaminations and 1,251,000 deaths. (Univ J Hopkins). This virus causes a pathology ranging from simple flu-like symptoms in 80% of cases to acute respiratory distress syndromes requiring intensive care in 5% of cases and a death rate of 1.4 to 4% of cases. Viral contamination is airborne and fecal A first epidemic wave crossed France in March / April 2020 then a second in October / November with a source of contamination which began in mid-August 2020. The sources of propagation are not well known (what places, what times, what contacts…? ) In the context of the health crisis linked to the coronavirus, knowledge of the sources of propagation of this 2nd wave is an important issue to guide end of lockdown and second lockdown policies.
The pandemic COVID-19 does not have an established treatment. Clinical trials of antiviral drugs against SARS CoV-2 are currently in progress. Clinical study done by NIH which included 1059 patients indicated that those who received Remdesivir had a median recovery time of 11 days as compared with 15 days in those who received placebo. Remdesivir has recently received full approval for COVID-19 by US FDA, and emergency use authorization (EUA) by multiple countries including European Commission and Indian Health Service. Remdesivir appears to demonstrate the most benefit in those with severe COVID-19 on supplemental oxygen. The NIH Panel recommends using Remdesivir for 5 days or until hospital discharge, whichever comes first. The interim analysis of WHO's SOLIDARITY trial, however, failed to show mortality benefit with Remdesivir. Review of literature suggests the transfusion of convalescent plasma has been used successfully in observational and retrospective studies. A recent metanalysis showed that convalescent plasma reduced mortality by 57% compared to matched-patients receiving standard treatments. The objective of NHRC sponsored initial clinical study protocol (Convalescent Plasma study) was to provide a coordinated approach for collection and preparation, distribution and guidance for safe and effective administration of convalescent plasma with antibodies against SAR CoV-2 for treatment of patients with COVID-19 infection who are most likely to benefit from this investigational treatment. On August 9th, 2020, the Government of Nepal gave permission to use Remdesivir in COVID-19 patients of Nepal only as a study drug when the original protocol was amended to add a second study arm to use Remdesivir for treatment of patients with moderate to severe COVID-19. The enrollment goal of these two protocols have been reached and collection of study data will be completed by the end of October 2020. On October 18th, the GoN MoHP also announced and directed to provide access for Remdesivir directly through the pharmacies. Therefore, this registry study has been designed to replace the compassionate use study of Remdesivir and Convalescent plasma.
Patients hospitalized for COVID-19 may need intensive care (e.g. mechanical ventilation) during hospitalization. Some risk factors are already known but better targeting of such patients is still needed, at least because existing risk factors are not strong enough to provide an accurate prediction. Care organization would benefit for such a predictive tool. Oropharyngeal and gut microbiota could potentially fill a significant gap in predictive performances. The investigators therefore propose to sample 200 patients (oropharyngeal and rectal swab) admitted in infectious disease department at Bichat Hospital and at high risk of needing intensive care during hospitalization. The investigators plan to perform metagenomic sequencing and bioinformatic analysis of these samples to characterize the diversity of bacterial species present in the oropharynx and the gut and to identify new factors associated with the need for intensive care. Aside metagenomic analyses, The investigators will perform semi-quantitative cultures of the oropharyngeal and gut microbiota to identify and quantify pathogens in order to predict the risk of bacterial infections in COVD-19 patients. For patients transferred in intensive care unit, The investigators will to perform another series of samples to better characterize the evolution of microbiota during mechanical ventilation and identify factors associated with the risk of developing a ventilator-associated pneumonia. Microbiota data will be considered together with the host genotype, the viral sequence and a deep immunological profiling to identify the main determinants of the evolution toward severity of COVID-19.
This study has 3 main goals: - to quantitavely describe the Covid-19 impact on the organization and functioning of the Lombardy's emergency system; - to create statistical model able to predict the flow of patients to the emergency room during the epidemic period and their destination (ex: discharge, hospitalization, death); - to value the impact on the non Covid-19 patients, both for their possibility to receive medical treatment and as an outcome on their health
In addition to primarily affecting the lungs, coronavirus disease-2019 (COVID-19) disease can also affect many different organs, especially the heart, kidneys, liver and brain. In this group of patients, the impact of an important organ such as the liver can lead to a further deterioration of the clinical course. In this study, critical patients admitted to Gazi Yasargil Training and Research Hospital intensive care unit (ICU) due to COVID-19 between April 1 and October 1, 2020 were retrospectively analyzed. The effect of liver damage on mortality in critical COVID-19 patients was investigated. The necessary permits for the study were obtained from the Scientific Research Platform of the T.R. Ministry of Health. (20.11.2020) Patients diagnosed with COVID-19 on the specified dates, followed in the ICU, older than 18 years, identified as critical/serious according to the World Health Organization and provisional guidelines of the Scientific Board of the T.R. Ministry of Health will be included in the study. ICU patients without COVID-19, COVID-19 patients under 18 years of age,COVID-19 patients with known liver disease, and COVID-19 patients with mild to moderate symptoms will be excluded from the study. Patients' age, gender, comorbidity, Acute Physiology and Chronic Health Evaluation II (APACHE II), Sequential Organ Failure Assessment (SOFA) scores when first admitted to the ICU, hemogram parameters (white blood cell count, neutrophil, lymphocyte, hemoglobin, platelet count), coagulation parameters (prothrombin time, activated partial thromboplastin time and D-dimer, blood biochemistry results (C-reactive protein, lactate dehydrogenase, creatine kinase , alanine aminotransferase (ALT), aspartate aminotransferase (AST), total bilirubin, direct bilirubin and indirect bilirubin), procalcitonin and ferritin levels will be recorded. In addition, the number of days spent in the ICU and whether mortality develops or not will be recorded. It will also be recorded whether mortality develops on day 7 and day 28. Patients will be divided into three groups according to their ALT, AST and total bilirubin levels at the time of admission to the ICU. Group 1 will consist of patients with normal ALT, AST and total bilirubin values. Group 2 will consist of patients whose ALT, AST or total bilirubin levels are up to 3 times upper limit of normal. Group 3 will consist of patients whose ALT, AST or total bilirubin levels are increased more than 3 times upper limit of normal.
The mental health of the French population in response to covid-19 pandemic is of concern. Health professionals are prone to more mental disorders due to their direct exposure to the pandemic consequences. Indeed, compared to general population, health care workers face enormous in the current health situation, especially those who may be in contact with suspected or confirmed cases (risk of infection, inadequate protection, loss of control, lack of experience in managing the diseases, overwork, stigma, lack of support). Thus, it seems interesting to describe the psychological state of hospital interns during this pandemic.
This study is a randomized, double-blind, multicenter, placebo-controlled trial to evaluate the safety and efficacy of a novel therapeutic agent, Novaferon, in hospitalized adult patients diagnosed with COVID-19. The study is comprised of two cohorts: - Cohort A: This is a blinded safety lead-in comprising two arms. 40 patients will be randomized on a 1:1 basis to receive either Novaferon or matched placebo via a commercial nebulizer, plus Standard of Care (SOC) - Cohort B: This is the main portion of the study, which comprises two arms. Up to 874 patients will be randomized on a 1:1 basis to receive either Novaferon or matched placebo via a commercial nebulizer, plus SOC
The purpose of this research study is to determine if a drug called fluvoxamine can be used early in the course of the COVID-19 infection to prevent more serious complications like shortness of breath. Fluvoxamine is an anti-depressant drug approved by the FDA for the treatment of obsessive-compulsive disorder. The use of fluvoxamine for the treatment of COVID-19 is considered investigational, which means the US Food and Drug Administration has not approved it for this use. This study is fully-remote, which means that there is no face-to-face contact; study materials including study drug will be shipped to participants' houses. People around the United States and Canada can participate.
An observational study of patients with COVID-19 confirmed cases (with various degrees of severity) and controls. Oral and nasal swabs will be taken from 150 patients (50 with mild form and 50 with severe form of COVID-19 with or without mechanical ventilation, 50 healthy controls).
