Active clinical trials for "Coronavirus Infections"

At present, the offer of tests for the serological diagnosis of CoVID-19 (detection of IgG, IgM or IgA antibodies against CoV-2 SARS) is plethoric and is based on the use of a very large number of rapid diagnostic unit tests, a few dedicated high throughput automated systems or reagents on existing open systems. The offer will continue to expand in the coming months. In order to meet the objectives mentioned by the Prime Minister, and confirmed in the HAS report of April 16, 2020 and in the opinion n°6 of the COVID-19 scientific council concerning the potential use of these serological tests at the end of the COVID-19 epidemic, the Virology laboratory wishes to validate the sensitivity and specificity of the tests it intends to use.

Citizens who undergo testing for COVID-19 at one of two Testcenters in Copenhagen Captial Region will be invited to participate in the study. The participants will be randomized to either an oropharyngeal swap including the palatine tonsils OR an oropharyngeal swap without the palatine tonsils for SARS-CoV-2 testing. The swabs will be sent to the clinical microbiology laboratory for SARS-CoV-2 detection using RT-PCR. The diagnostic accuracy and SARS-CoV-2 viral load will be compared. The participants will be asked to complete a questionnaire regarding their symptoms.

In light of the rapidly emerging pandemic of SARS-CoV-2 infections, the global population and health care systems are facing unprecedented challenges through the combination of transmission and the potential for severe disease. Acute respiratory distress syndrome (ARDS) has been found with unusual clinical features dominated by substantial alveolar fluid load. It is unknown whether this is primarily caused by endothelial dysfunction leading to capillary leakage or direct virus induced damage. This knowledge gap is significant because the initial balance between fluid management and circulatory support appear to be decisive. On progression of the disease, bacterial superinfection facilitated by inflammation and virus related damage, has been identified as the main factor for patient outcome, but the role of the host versus the environment microbiome remains unclear. The overarching aim of the present research proposal is to improve therapeutic strategies in critically ill patients with ARDS due to SARS-CoV-2 infection by advancing the pathophysiological understanding of this novel disease. This research thus focuses on inflammation, microcirculatory dysfunction and superinfection, aiming to elucidate risk factors (RF) for the development of severe ARDS in SARS-CoV-2 infected patients and contribute to the rationale for therapeutic strategies. The hypotheses are that (I) the primary damage to the lung in SARS-CoV-2 ARDS is mediated through an exaggerated pro-inflammatory response causing primary endothelial dysfunction, and subsequently acting two-fold on the degradation of the lung parenchyma - through the primary cytokine response, and through recruitment of the inflammatory-monocyte-lymphocyte-neutrophil axis. The pronounced inflammation and primary damage to the lung disrupts the pulmonary microbiome, leading secondarily to pulmonary superinfections. (II) Pulmonary bacterial superinfections are a significant cause of morbidity and mortality in COVID-19 patients. Pathogen colonization main Risk Factor for lower respiratory tract infections. To establish colonization, pathogens have to interact with the local microbiota (a.k.a. microbiome) and certain microbiome profiles will be more resistant to pathogen invasion. Finally, (III) Handheld devices used in clinical routine are a potential reservoir and carrier of both, SARS-CoV-2, as well as bacteria causing nosocomial pneumonia.

Popular topic：Clinical study on the immune program of recombinant Novel Coronavirus (COVID-19) vaccine (CHO cell). Research purpose:Main purpose: To evaluate the immunogenicity of recombinant novel coronavirus vaccine (CHO cells) inoculated at 0,1,6 months or 0,1,4 months in persons aged 18 years and over. Secondary purpose: To evaluate the safety of the investigational vaccine in people aged 18 and above. Overall design: In this study, recombinant novel coronavirus vaccine (CHO cells) is inoculated at 0,1,6 months or 0,1,4 months in persons aged 18 years and older to evaluate the immunogenicity and safety. Study population:The study involved people 18 years of age and older. Test groups：A total of 300 subjects were enrolled, including 221 in the 18-59 age group and 79 in the ≥60 age group. Three doses of experimental vaccine were administered according to the 0,1,6 month immunization schedule (Study No. 001-150) or 0,1,4 months immunization schedule (Study No. 151-300).

The study will be a two center, randomized, double blind, placebo controlled study of the MVA MERS S_DF-1 candidate delivered by i.m. injection. To evaluate the MERS-S-specific antibody responses and safety profile induced by the two dosage levels of MVA-MERS-S_DF-1 the data will be compared to a placebo control group.

Novel coronavirus pneumonia (NCP) and acute respiratory distress syndrome (ARDS) are both associated with the prevailing upper respiratory tract infections caused by the RNA-containing SARS-CoV2 virus of the genius Betacoronavirus of the Coronaviridae family. As both the viral infiltration and infection progress, the host immune system response can be one of a rapidly developing fatal cytokine storm. In the ARDS or NCP ensuing progression, the patient often succumbs to the effects of the hyper pro-inflammatory response, hence contributing to the associated increased mortality as a result of the cytokine storm and associated pathogenesis.

Background: People who get COVID-19 have a wide range of symptoms. They also recover from COVID-19 in different ways. In this study, researchers will use survey data to describe the different ways people experience and recover from COVID-19. They will also use the data to help create future studies to understand why some people do not fully recover. Objective: To learn more about the range and timing of symptoms that people have before, during, and after COVID-19 infection. Eligibility: People ages 18 and older who can give documentation of a positive COVID-19 or antibody test. Design: Participants will be screened with a telephone interview. It will take 15 minutes. They will provide their COVID-19 test results and medical records. Participants will complete a second telephone interview. It will take 30 60 minutes. They will also take online surveys every 3 months for 3 years. The interview and surveys will ask participants about their health before they got COVID-19, what happened while they had COVID-19, and what their recovery has been like. Participants will get log-in data to take the online surveys. Completing all of the surveys the first time may take up to 3 hours. Follow-up surveys will take up to 30 minutes. Participants do not have to complete the surveys in one sitting. They will be able to save their progress and finish the surveys later. Participants may be contacted to take part in other research studies.

It is unknown what proportion of healthy children have been exposed to SARS-Cov-2 and how many have antibodies. The aim of this study is to follow a cohort of healthy children over six months and measure their antibodies to SARS-CoV-2.

The novel coronavirus (SARS-CoV-2) has spread all around the world and testing has posed a challenge globally. Health care providers are highly exposed and are an important group to test. On top of these concerns, health care workers are also stressed by the needs on responders in the COVID-19 crisis. The investigators will look at different ways to measure how common COVID-19 is among health care workers, how common is the presence of antibodies by serological tests (also known as serostatus). The investigators will describe health worker mental and emotional well-being and their coping strategies in their institutional settings. Lastly, the investigators will describe how knowing serostatus can affect individuals' mental and emotional well-being and how to cope in the midst of the COVID-19 response. This will help to how to better test and help healthcare workers in the COVID-19 pandemic and prepare for possible future outbreaks.
