Active clinical trials for "Coronavirus Infections"

Background: Corona virus disease 2019 (COVID-19) is a highly infectious disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Purpose: To give initial experience about COVID-19 in Alexandria-Egypt describing radiological patterns of lung involvement, also surveying prevalence of co-morbid lung diseases and their effect on COVID-19 presentation. Methods: Retrospective study including 48 patients with positive polymerase chain reaction (PCR) test for COVID-19 during the period from February 2020 till May 2020 in Alexandria/Egypt. Full clinical and laboratory data are obtained. High resolution computed tomography (HRCT) findings are described. Serial follow up studies are done. Surveying co-morbid lung diseases done including tuberculosis (TB), interstitial lung diseases (ILDs), chronic obstructive lung disease (COPD), immune and vascular-related diseases. Prevalence rate is the predominant analysis.

Clinical observation has found that COVID-19 patients often present inconsistency of clinical features, nucleic acid of the SARS-CoV-2 and imaging findings, which brings challenges to the management of patients.The quantitative assessment of patients' pulmonary lesions of chest CT, combined with the basic information, epidemiological history, clinical symptoms, basic diseases and other information of patients, will quickly establish a reliable prediction model for the severe COVID-19. This model will greatly contribute to the effective diagnosis and treatment of COVID-19.

Testing use of predictive analytics to predict which COVID-19+ patients are at low risk for an adverse event (ICU transfer, intubation, mortality, hospice discharge, re-presentation to the ED, oxygen requirements exceeding nasal cannula at 6L/Min) in the next 96 hours

COVID infection has resulted in multi-organ injury and may result in cardiovascular, pulmonary, neurological, and muscular damage. It is associated with significant asthenia and the long-term effects of the infection are still unclear, particularly for the development of pain and delayed functional rehabilitation. Glycomics "is the systematic study of the structure of glycans in a given cell type or organism. Glycans are complex oligosaccharides attached to proteins and lipids that regulate a variety of organic processes, including immunity Thus, glycans may influence different moments of the response to the virus and involved in the clinical severity of the disease, but may also change depending on the severity of symptoms and the organic response to SARS-CoV-2 infection. Glycomic data could provide important insights into interindividual differences at the molecular level that directly interact with SARS-CoV-2 and the development of mid- and long-term side effects. The ability to identify early those susceptible to developing COVID-19 infection and at higher risk for COVID-19 with unfavorable outcomes long after infection would help guide therapeutic strategy and provide important guidance for rational health care organization, which is of outmost importance. Long-term outcome data regarding post-COVID patient functional capacity and glycomics will be compared to assess whether there may be differences in protein glycosylation that may predict patient outcome.

The purpose of this study: to assess the safety, tolerability and immunogenicity of the drug "Gam-COVID-Vac", a solution for intramuscular injection, at various times after vaccination in volunteers over 60 years of age

COVID-19 pneumonia can cause severe acute hypoxemic respiratory failure. The usefulness of noninvasive respiratory support (NIRS), by means of nasal high-flow oxygen (NHFO), continuous positive airway pressure (CPAP), or noninvasive ventilation (NIV), established outside the intensive care unit, is unknown. The aim of this multicenter, retrospective, longitudinal study is to compare the effectiveness of these treatments to prevent death or endotracheal intubation at day 28, and what factors, related to the disease or to the characteristics of the treatment itself, can condition its success or failure.

Since the end of 2019, Egypt and the whole world have been suffering from the Coronavirus Disease 2019 (COVID-19) pandemic, which is caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). According to the World Health Organization (WHO), since the emergence of this new pandemic, there have been more than 97 million confirmed cases of COVID-19 patients and two million death globally; around 160 thousand of these cases are in Egypt. Tocilizumab play role among the unique therapeutic alternatives for the management of cytokine release syndrome (CRS), a life-threatening complication of chimeric antigen receptor (CAR) - T cell therapy. CRS occurs as a result of uncontrolled immune activation with release of pro-inflammatory cytokines and chemokines. Up till now, clinical trial and expertise with tocilizumab in COVID-19 patients has been limited. Despite preliminary encouraging results, recent studies suffered from limitations such as the absence of consistent treatment outline, a short post-treatment follow-up, and the absence of a comparison group. A recent study discussed the possible beneficial effect of tumor necrosis factor (TNF) inhibitors in severe COVID-19. Specifically, TNF may aggravate lymphopenia through direct killing via TNF/TNFR1 signaling in T cells, and T cell dysfunction reveals an important yet underestimated target for immunomodulatory therapeutic approaches. Accordingly, anti-TNF may be considered as an encouraging therapeutic option in severe COVID-19. These promising clinical findings encouraged us to use infliximab (IFX), a chimeric monoclonal anti-TNF antibody, as an experimental therapy in patients with moderate and severe COVID-19 in the absence of IBD. In this study, we compare the outcomes of a large cohort of patients with moderate and severe COVID-19 pneumonia treated with tocilizumab in addition to standard management, with those of concomitantly hospitalized patients who received infliximab and tocilizumab in addition to standard management.

Effectiveness of the use of Tenofovir/Emtricitabine in addition to personal protective equipment for the prevention of the transmission of SARS-COV-2 to health care personnel. A Randomized Clinical Trial. This is an experimental study whose aim is to evaluate the effectiveness of a drug to prevent infection with the virus that causes COVID-19 (SARS-CoV-2), in health care workers. The drug under study is Tenofovir /Emtricitabine, a well-known antiretroviral, which is safe and is used as prophylaxis and treatment for HIV and other viral infections such as Hepatitis. Several laboratory-based studies indicate that this drug has the potential to inhibit SARS-CoV-2 replication. In addition, one study in HIV infected persons found that those taking Tenofovir /Emtricitabine tended to have a lower occurrence of COVID-19. In this study, we will compare the occurrence of infection with SARS-CoV-2/ COVID19 in health care workers between those assigned to an intervention group and those assigned to a control group. The intervention group will receive Tenofovir /Emtricitabine during 60 days in addition to the use of personal protective equipment (PPE), and the control group will receive a placebo during 60 days in addition to the use of personal protective equipment (PPE). The study will recruit 950 health professionals above 18 and less than 70 years, working in the emergency room, COVID wards and intensive care units of seven hospitals in Colombia. To make the comparison groups very similar, the participants will be assigned through a random mechanism to either the intervention (475), or the control (475) groups. In order to prevent biases in the evaluation of the results, neither the participants nor the clinical investigators, data managers, analysts and support personnel will know which intervention the participants are receiving. To determine the occurrence of infection with the virus the study will use both molecular tests that detect the presence of viral genes in respiratory secretions, and serological tests that detect the response of the immune system to the virus. The study will evaluate also the safety of this drug determining the occurrence of adverse events.

Background The study aimed to establish the seroprevalence of SARS-COV-2 in an Argentinian slum three months after the first case was reported. Methods Between June 10th and July 1st, a cross-sectional design was carried out on people over 14 years old, selected from a probabilistic sample of households. Finger prick puncture ELISA test

In this protocol, we seek the understand the demographics of individuals who have used the TraceTogether mobile application. Little is known about the group of individuals who are more likely to utilise the application. Hence, this study hopes to: (1) Understand the demographics of Singaporeans who use and do not use TraceTogether, (2) Identify other behavioural habits of people who do use TraceTogether, (3) Determine if confidence in government would have any effect on TraceTogether usage
