Active clinical trials for "Severe Acute Respiratory Syndrome"

This study is randomized, double-blind (blinded for the trial subject and the study physician), placebo-controlled trial in the parallel assignment of the immunogenicity, and safety of the Gam-COVID-Vac combined vector vaccine against the SARS-CoV-2-induced coronavirus infection in adults in the SARS-СoV-2 infection prophylactic treatment.

The prevalence of SARS-CoV-2 infection in chronic inflammatory rheumatic diseases has not yet been widely reported, and has been evaluated only in symptomatic patient samples. The proportion of asymptomatic or mildly symptomatic patients is unknown, in patients who share common symptoms with CoV-2-SARS infection. Our objective is to describe the prevalence of seroconversion to CoV-2-SARS by consecutive screening in routine care of patients with chronic inflammatory rheumatism with serological testing

In this randomized double blind Phase 3 clinical trial we will study the efficacy and safety of oral polio vaccine with and without NA-831 versus placebo.

While many people with COVID-19 suffer from respiratory disease, there is growing evidence that the virus also affects other organs. The purpose of this study is to better understand the effects of COVID-19 on the lungs and other organs. The study investigators have developed new techniques in Magnetic Resonance Imaging (MRI) to scan the lungs, heart, brain and liver. The study investigators hope to learn more about how the virus causes inflammation in these organs and how this inflammation changes over time as people recover from COVID-19 illness. The study aims to enroll 228 people in Alberta. Participants will undergo one or more MRI scans and have blood testing at one or more time points to assess for inflammation, kidney function, liver function and possible heart injury. Participants will also undergo testing to assess sense of smell, cognition (thinking and memory), spirometry (breathing test for lung function) and and exercise tolerance (walk test). The study investigators hope this study will help us learn more about the long-term risks of COVID-19 disease.

Adaptive immune responses are essential for clearing viral infections and retention of virus specific memory populations is required for long-term immunity. However, there is still uncertainty about whether adaptive immune responses to SARS-CoV-2 are protective. Such knowledge is of immediate relevance, as it will provide insights into immunity of SARS-CoV-2 infection and thus help define future immunization strategies. Because of the importance of asymptomatic cases in children, a specific study is needed in this population in order to determine their individual and collective protective capacity. This is even truer for immune compromised children that likely have severe forms of the disease with active and prolonged viral replication in whom it is therefore essential to determine the extent of sero conversion but also the quality and duration of the memory responses. For this purpose, we plan to analyze the anti-SARS-CoV-2 humoral and memory T cell responses, in different groups of immuno-compromized children (i.e with different levels/type of immunosuppression; HIV, renal or stem cell transplantation, anti-TNF or methotrexate treatment) and healthy controls seen in 3 University Hospitals, in order to determine the proportion of children with SARS-CoV-2 specific humoral responses, their protective capacity, the magnitude and the quality of the SARS-Cov-2 memory T cells but also their long term persistence at 1 year.

The new Severe acute respiratory syndrome coronavirus (SARS-CoV-2) named coronavirus disease 2019 (COVID-19) is currently responsible for a pandemic spread of febrile respiratory infections, responsible for a veritable global health crisis. In adults, several evolutionary patterns are observed: i) a/pauci-symptomatic forms; ii) severe forms immediately linked to rare extensive viral pneumonia; and iii) forms of moderate severity, some of which progress to secondary aggravation (Day 7-Day 10). Children can be affected, but are more rarely symptomatic and severe pediatric forms are exceptional. Like some other coronaviruses (SARS-CoV and Middle East respiratory syndrome coronavirus (MERS-CoV)), these differences in clinical expression could be based on a variability in the immunological response, notably either via inhibition of the type I interferon (IFN-I) response, or on the contrary an immunological dysregulation responsible for a "cytokine storm" associated with the aggravation. Little is known about the impact of these innate immune response abnormalities on the adaptive response. In addition, certain genetic factors predisposing to a state of "hyper-fragility" and certain viral virulence factors could also be predictive of the clinical response. In this context, the main hypothesis is that the virological analysis and the initial biological and immunological profiles are correlated with the initial clinical presentation of COVID-19 infection. In particular, children forms and pauci-symptomatic disease in adults may be linked to a more robust innate immune response, including better production of IFN-I.

The purpose of this study is to determine how peoples' bodies respond to exposure to COVID-19. Employees of Beaumont Health in Michigan who are older than 18 years may be eligible to participate. Participants from other high-risk groups who are not Beaumont employees may also be recruited, as may family members of Beaumont employees who have tested positive for COVID-19. Participants will have blood drawn two or more times for serology testing. This serology test will determine if participants have detectable levels of the antibodies that our bodies develop to fight COVID-19 infection. Participants will fill out a questionnaire each time they provide a blood sample. The questionnaires include questions about participants' personal traits; their health; general questions about their risk to exposure; job and risk of exposure; symptoms, diagnosis, treatment of COVID-19 since last blood draw. Researchers will monitor participants' medical records in a confidential manner for one year after the last blood draw to help determine if people who develop antibodies to COVID-19 are protected against developing a COVID-19 infection in the future.There may be no direct benefits for participants; however, information from this study may benefit other people by increasing our understanding of COVID-19, how it spreads from person to person, and how people respond to fight off the infection.The results of the serology test are used for research only and will not affect clinical decisions regarding participants' treatment or quarantine

The aeronautical community was also affected and greatly impacted economically and socially by the Covid-19 pandemic. Away from the acute phase, the epidemiological impact and the consequences of this disease within the French aviation flight crew population must be assessed. This study is aimed at providing original epidemiological data among civil and military aircrew, prior to possible prevention strategies or countermeasures to optimize risk management in terms of aviation safety and to promote, if necessary, future targeted studies.

Minimal risk research study: Comparing polyester nasal swabs and foam nasal swabs to detect SARS-CoV-2 virus; Quantifying the development and trajectory of the disease through clinic visits and blood values.

This observational study will collect data from patients treated with siltuximab program for treatment of SARS-CoV-2 infection complicated with serious respiratory complications. This observational study will group the patients into two cohorts receiving siltuximab.. Outcome of patients will be compared to a cohort of patients receiving standard treatment without siltuximab. The patients will be divided into 2 cohorts. Those contained in Cohort A were treated after the use of continuous positive airways pressure (CPAP) or non-invasive ventilation (NIV). Patients in Cohort B were treated after intubation
