Active clinical trials for "Severe Acute Respiratory Syndrome"

This is a registry-based cohort study of all adult patients (≥18 years) with confirmed or suspected SARS-CoV-2 infection. The main goal is to describe mortality incidence, demographic characteristics, coexisting conditions, treatments, outcomes among SARS-CoV2 infected patients. A secondary goal is to identify biological factors (OMICS - genomic, proteomic and metabolomics characterization) associated with severity conditions for these patients.

To better understand the role of inflammation in COVID-19, we established the Michigan Medicine COVID-19 Cohort (M2C2). M2C2 is a funded and ongoing cohort which has currently enrolled over 1500 adult patients (≥18 years) with severe COVID-19 admitted at the University of Michigan. The purpose of M2C2 is to define the in-hospital course of these patients and understand the role of inflammation as a determinant of organ injury and outcomes in COVID-19.

Acute Respiratory Distress Syndrome (ARDS) is the main clinical presentation of SARS-CoV-2 (Covid-19) infected patients admitted in Intensive Care Unit (ICU). During the first phase of the outbreak (between February and May 2020), the use of invasive Mechanical Ventilation (MV) was largely required with 63% of ICU patients intubated in the first 24 hours after admission and up to 80% of patients during the overall ICU stay. Mortality was especially higher when using MV in the first 24 hours. In contrast, the use of non-invasive oxygenation strategies in the first 24 hours was only 19% for High Flow Nasal Cannula oxygen therapy (HFNC) and 6% for Non-Invasive Ventilation (NIV). Several non-invasive oxygenation strategies were proposed in order to delay or avoid MV in ICU patients suffering from Covid-19 ARDS. The use of HFNC became the recommended oxygenation strategy, based in particular on publications prior to the outbreak. The use of NIV or Continuous Positive Airway Pressure (CPAP) combined with HFNC have also been proposed. Although these non-invasive oxygenation strategies seem widely used in the second phase of the outbreak, they have not yet confirmed their clinical impact on MV requirement and patient's outcome. Moreover, no comparison has been made between these different non-invasive oxygenation strategies. The aim of this study is to compare different non-invasive oxygenation strategies (HFNC, NIV, CPAP) on MV requirement and outcome in ICU patients treated for ARDS related to Covid-19.

Severe Acute Respiratory Syndrome (SARS) is a newly recognized illness that can be fatal. The purpose of this study is to better understand SARS by collecting samples of blood and other body fluids of people who have been exposed to SARS or who are suspected to have the illness. Up to 300 volunteers aged 18 years or older will be enrolled in this study. Participants will donate blood samples and, if appropriate, samples of fluid from the lungs, nose, or throat. Researchers will test these samples for proteins that control or mediate inflammatory or immune responses. The patterns of these proteins will reveal how SARS affects the body and the efforts the body makes to fight off the infection.

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.

Disproportionate impact of COVID-19 in patients with obesity is now well established. Obesity is associated with severe forms of COVID-19 and may be a risk factor of intensive care unit (ICU) admission. Obesity is associated with COVID-19 related hospital death in a large United Kingdom cohort study. However, there is a gap of knowledge on assessment of outcomes such as severity of Acute Respiratory Distress syndrome (ARDS), duration of hospitalisation and mortality in ICU. Moreover, an obesity survival paradox has been observed in patients with ARDS. This raises the question whether the obesity paradox has been broken by COVID-19. The investigators aim to explore risk factors of in-ICU death for patient with COVID-19, including obesity and other chronic diseases and to describe the clinical course and outcomes, including the management of acute respiratory failure and other intensive care management.

The aim of the cohort prospective observational study is to define the major factors influencing the course of COVID-19 infections and its prognosis in hospitalised patients. The investigators plan to include 300 patients hospitalised with COVID-19 infection. The phone contacts with patients are due after 90 and 180 days after discharge.

Breath gas analysis is the evaluation of exhaled breath. It aims to evaluate the volatile organic compounds (VOCs) in exhaled breath. In this feasibility study it is intended to find specific peaks/pattern in exhaled breath indicating an infection with SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2).

Based on studies in China, Iceland, the Netherlands and Italy it seems that children are less affected by SARS-CoV-2 infections and play a lesser role in the dissemination of the SARS-CoV-2 virus. It is unclear to which extend this is due to lesser exposure or an inherent decreased susceptibility to become infected. The low reported number of cases in children can be partially explained by the lower testing rates in the pediatric population. To get insight in the transmission of SARS-CoV-2 virus in school-aged children it is necessary to compile data on infection of SARS-CoV-2 virus in the child and (pre-)adolescent population. The main objective of this study is to determine the sero-prevalence and sero-conversion of antibodies against SARS-CoV-2 in a sample of school-aged children (primary and secondary school) in Belgium at different time points. Additionally this study will gain insight in the incidence of SARS-CoV-2, the proportion of asymptomatic infections with SARS-CoV-2 and the role of COVID-19 infection in household members. It will give us the possibility to investigate potential risk factors for infection. The study population includes primary and secondary school children from two predefined age groups (8-9 and 13-14 years old). These two groups are chosen because studies have shown more pronounced symptoms of infection and disease depending on age and because transmission dynamics also vary by age. The study population will be recruited in all Belgian schools including Brussels-Capital, Flemish and Walloon Region (including the German speaking community). The study is a prospective cohort study. In total there will be 3 testing points with 3 months between each point. The sample size calculation indicated the inclusion of 41 randomly selected primary and 41 secondary schools and in each school 20 randomly selected pupils of the defined age groups. Parents/legal child caregiver will complete a questionnaire at each of the testing points providing basic socio-demographic characteristics (at baseline only) and risk-behavior and health characteristics including presence of symptoms during the time since the previous testing point (at each of the testing points). The questionnaire will be completed through a secured online application during the same week as the child had the saliva sample for serological testing taken. Saliva samples will be sent to the Sciensano laboratory for serological analysis. The child's parent/legal caregiver will be informed of the serological result. Study data will guide the Belgian policy makers in their advices to limit circulation of SARS-CoV-2 in Belgium and more specifically in their advice on measures for school-age children. This data might also be used to guide health authorities that have to decide on vaccination strategies once a vaccine is available; to decide whether children should be included for vaccination to create herd immunity or not.

Since March 2020, the SARS-CoV type coronavirus infection (SARS-CoV-2; nCoV19; COVID-19) is considered pandemic. As early as April 2020, the World Health Organization recommended the implementation of mass screening of populations, with the aim of identifying cases and contacts and controlling viral spread. Since the end of lock-down on May 11, 2020,the screening policy has been intensified to fight against COVID-19. Virological tests by RT-PCR are thus accessible to all, without a prescription and reimbursed by health insurance. The French government has also set a quantitative target of 1 million tests per week. In order to meet this target, the number of sampling centers has been increased (mobile structures, etc.). Screening tests are currently carried out using a nasopharyngeal swab analyzed by RT-PCR for the detection of viral RNA. This type of sample has several technical and logistic constraints. It must be carried out by personnel who are authorized and trained in this procedure and in appropriate hospital hygiene practices. It exposes the sampling personnel to possible contamination through nasopharyngeal secretions or coughing that may occur during sampling. With the increase in screening, there are sometimes insufficient numbers of sampling personnel and there is significant market pressure for swabs and virological transport media. In addition, these swabs are uncomfortable or even painful for the patient, which could imply a reluctance to be screened. They are also complicated in children, whether they are rhino- or oropharyngeal. An alternative to the nasopharyngeal swab, which is the subject of this project, would be to have one or more reliable sampling methods that are less restrictive than the nasopharyngeal swab ("gold standard"). Thus, we propose to test and compare the results obtained by molecular biology techniques on nasopharyngeal, salivary and buccal swabs.
