Active clinical trials for "COVID-19"

Retrospective study from November 2019 -Febrauary 2020 on severe respiratory illness to access the presence or absence of COVID-19 in patients samples by real-time PcR

This is an observational study, meaning that no interventions is tested, to determine incidence of SARS-CoV-2 infection and COVID-19 in different clinical sites in Brazil in several age groups. The study aims to assess baseline number of infected participants and perform a follow-up along two years to determine the new cases occurring among participants during the period. All participants will collect blood samples to get more details on the immune response.

The outbreak at covid-19 is caused by the SARS-CoV-2 virus. This virus can be responsible for severe respiratory failure but also for extra-respiratory organ dysfunctions associated with severe inflammatory stress. The endothelium is an important structure of the blood vessels and is implicated in the organ failure of many patients admitted in intensive care units. It could be affected by the virus and its alteration may explain the organ dysfunction of covid-19 ICU patients as well as the thrombotic processes frequently obstructed in this infection.

The primary goal of the study is to conduct the first systematic cardiac autopsy study in 60 patients dying from COVID-19 to understand the pathology and pathogenesis of cardiac injury in patients with COVID-19, with/without cardiovascular comorbidities. Such data is essential for understanding rate of involvement, type of involvement and degree of injury in patients contracting the disease.

The aims of the present study are: To explore the impact of COVID-19 pandemic on the smoking behavior of youth smokers To explore the impact of COVID-19 pandemic on the Youth Quitline service in Hong Kong

The purpose of this registry study is to investigate the effectiveness and safety of the Seraph® 100 Microbind® Affinity Blood Filter (Seraph 100) in the treatment of COVID-19 patients.

A descriptive study that will quantify the mean IgG antibodies remaining in vaccinated healthy participants after their COVID booster.

This study is a comparison of the ID Now COVID-19 (Abbott) assay to the Accula SARS-CoV-2 (Mesa Biotech) assay to assist in the identification of infection with COVID-19. The tests will be compared for sensitivity, specificity, positive predictive value and negative predictive value.

The purpose of this study is to assess the immunogenicity of nationally available pre-defined homologous booster vaccination of a SARS-CoV-2 WHO EUA qualified vaccination in adults aged 18 years and older

As of February 17th, 2020, China has 70635 confirmed cases of coronavirus disease 2019 (COVID-19), including 1772 deaths. Human-to-human spread of virus via respiratory droplets is currently considered to be the main route of transmission. The number of patients increased rapidly but the impact factors of clinical outcomes among hospitalized patients are still unclear.
