Active clinical trials for "Coronavirus Infections"

The Middle East respiratory syndrome coronavirus (MERS-CoV) was identified in 2012 during the first Middle East respiratory syndrome (MERS) outbreak. MERS-CoV causes an acute lower-respiratory infection in humans, with a fatality rate of ~34.5%. The aim of the study is to assess the safety and immunogenicity of adenoviral-based vaccine against MERS - BVRS-GamVac.

Background: During the current COVID-19 pandemic there is urgent need for information about the natural history of the infection in non-hospitalized patients, including the severity and duration of symptoms, and outcome from early in the infection, among different subgroups of patients. In addition, a large, real-world data registry can provide information about how different concomitant medications may differentially affect symptoms among patient subgroups. Such information can be invaluable for clinicians managing chronic diseases during this pandemic, as well as identify interventions undertaken in a naturalistic setting that have differential effects. Such factors may include patient diet, over the counter or prescription medications, and herbal and alternative treatments, among others. Identifying the natural disease history in patients from different demographic and disease subgroups will be important for identifying at-risk patients and effectiveness of interventions undertaken in the community. Objectives: The purpose of this study is to understand at the population level the symptomatic course of known or suspected COVID-19 patients while sheltering-in-place or under quarantine. Symptoms will be measured using a daily report derived from the CTCAE-PRO as well as free response. Outcomes will be assessed based on the duration and severity of infection, hospitalization, lost-to-follow-up, or death. As a patient-centric registry, patients themselves may propose, suggest, and/or submit evidence or ideas for relevant collection.

Since Dec 2019, over 70000 novel coronavirus infection pneumonia (NCIP) patients were confirmed. 2019 novel coronavirus (2019 nCoV) is a RNA virus, which spread mainly from person-to-person contact. Most of the symptoms are non-specific, including fever, fatigue, dry cough. Sever NCIP patients may have shortness of breath and dyspnea, and progress to acute respiratory distress syndrome (ARDS) and multiple organ dysfunction syndrome (MODS). The mortality is reported to be around 2.3%. Thus, early detection and early treatment is very important to the improvement of NCIP patients' prognosis. At present, NCIP RNA detection of pharyngeal swab specimen by RT-PCR is recommended. However, due to the universal susceptibility to 2019 nCoV in general population and limited number of NCIP RNA detection kits available, to identify an efficient screening strategy is urgently needed. This study aim to develop and validate the diagnostic accuracy and screening efficiency of a new NCIP screening strategy, which can benefit the disease prevention and control.

COVID-19 has adversely affected the healthcare system across the world. The world was not prepared for global outbreak of infectious diseases. The rapid spread of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is enabling researchers worldwide to acquire a large amount of clinical data regarding coronavirus disease (COVID-19). The COVID-19 infection severely affects the respiratory system in the critical cases and results in mortalities. The affected people experience a dry cough, fever, breathing problems, diarrhea, muscle pain, and sore throat. Besides that, some of the evidence from Italy, South Korea, China, and Spain suggest that the COVID-19 cases also lose their senses of smell and taste resulting in alterations in those patients. The objective of this proposed study is to determine whether COVID-19 cases have Olfactory and gustatory dysfunctions as a hallmark indicator and can be used as diagnostic tools for the isolation of suspected people. Investigators are presenting a prospective proportional case-control study that is conducted to investigate the COVID-19 cases with anosmia and /or Ageusia in a university hospital in Riyadh, Saudi Arabia. The sample size of this case series would be 250 cases of suspected COVID-19 patients. The cases included in the study are analyzed prospectively to determine if the cases had a history of anosmia and /or Ageusia, and then tested for the alteration of these senses through a panel of standardized odors/taste strips. That is looked at statistically allowing us to confirm the proposed effectiveness of these tests as a diagnostic tool.

COVID-19 pandemic has developed worldwide in less than 4 months. While most patients have a mild or uncomplicated disease (80%), approximately 15% need hospital care and 5% intensive care. Severe cases are characterized by pulmonary involvement which may progress to acute respiratory distress syndrome (ARDS). Early identification of patients who are likely to get worse is therefore a major issue. While, chest X-ray has poor diagnostic performances, pulmonary computed tomography (CT scan) seems very sensitive (97%) and quite specific of COVID-19. Sub-pleural bilateral ground-glass pattern can precede the positivity of RT-PCR for SARS-CoV-2. CT scan is now considered as the best imaging test to assess COVID-19 patients and is recommended as first-line diagnosis tool by the French Society of Radiology (SFR). However, performing CT scan in all or many patients with suspected COVID-19 may result in radiology department overload, especially, taking into account bio-cleaning between patients. Moreover, CT scan may lead to adverse effects including induced cancer due to the cumulative diagnostic irradiation. Chest ultrasonography may be an alternative to CT scan. It is a simple, non-invasive, non-irradiating, inexpensive and available at the point of care (POCUS). Most of emergency physicians and many other specialists (pneumologists, infectious disease or intensive care physicians) are trained to perform chest POCUS and use it in their everyday practice. Multiple studies have demonstrated its superiority to chest X-ray for the detection of pneumonia. In ARDS, a scoring has been developed and has shown good correlation with mortality. POCUS is very effective in detecting peripheral patterns and seems appropriate to explore COVID-19 patients. Previous studies suggest its interest in SARSCov2 infections for initial patient assessment and identification of lung damage. However, its performances have never been scientifically evaluated to date. Our main hypothesis is that point of care lung ultrasonography performed during the initial examination may identify high-risk COVID-19 patients.

The aim of the study is to demonstrate overactivation of Renin Angiotensine System (RAS) in positives COVID-19 patient, especially in those with the most serious clinical forms where the mortality of patients in intensive care is on average 50%. We are expecting two groups: a group of 25 positive COVID 19 patients in intensive care and a group of 25 positive COVID 19 hospitalized patients in conventional hospitalisation. We will measure RAS, serum potassium and collect data on the treatment of these patients (especially antihypertensive therapy) one week apart (at the patient'entry into hospital and 7 days later). This is a preliminary study that could possibly allow the start of a therapeutic trial in order to test the effectiveness of RAS blocker treatments in this condition.

The purpose of this study is to determine whether the virus SARS-CoV-2, responsible for the disease COVID-19, is present in the abdominal cavity during emergency laparoscopic exploration in confirmed or suspected COVID-19 patients.

Blood samples from participants who have recovered from COVID-19 infection will be obtained and studied. The goal of the research is to identify antibodies that have been generated by the patient to fight the COVID-19 infection. By identifying the most effective antibodies, scientists can make specific antibodies to use to prevent future coronavirus outbreaks or to treat patients with severe disease.

For preventing the overwhelming of ICU beds capacity during COVID-19 pandemic in France, national and regional Health-Care institutions decided to optimize the Intensive Care Unit beds availability by opening new ICU beds in institutions with and without prior ICU. The Present study was design to retrospectively describe the origin of the ICU beds and human resources created during the COVID-19 outbreak in France.

The COVID-19 pandemic has highlighted deleterious US health inequities. Specifically, African Americans, Latinos, and Native Americans have and continue to shoulder a greater burden of COVID-19 infections and deaths in the US. In addition to existing racial and ethnic disparities are rural health and regional disparities. Given the disproportionate impact of disease in US communities of color and also in rural and southern regions of the US, there is no doubt that these at-risk subgroups will continue to experience higher rates of coronavirus-related mortality as well as other long-term health outcomes as compared to other US populations. It is unknown how healthcare providers and other key at-risk subgroups within the US will receive COVID-19 vaccines. For success in immunizations, the US will need to reach their most at-risk and vulnerable populations. In addition to at-risk populations, a successful immunization strategy will involve engaging providers to support clear, consistent, and strong vaccine recommendation. It is critical to build vaccine trust, confidence, and overall acceptance of COVID-19 vaccines among healthcare providers and key at-risk subgroups, especially given the accelerated production timeline of these vaccines. Likewise, tailored vaccine messaging for key subgroups is vital in achieving vaccine confidence and trust. The proposed study will explore perceptions, confidence, trust, and uptake of potential COVID-19 vaccines among healthcare providers (nurses and doctors) and key at-risk population subgroups (minority populations living in the rural south) and will develop and test vaccine messaging that boosts vaccine confidence and trust among these key at-risk subgroups.
