Active clinical trials for "COVID-19"

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.

This study will explore how a well-known probiotic strain L. reuteri DSM 17938 impacts SARS-CoV-2 specific antibody response upon and after infection in healthy adults.

The main of the study is to describe the incidence in health personnel who present events supposedly attributed to vaccines and immunizations after having received the two components of the Sputnik V vaccine, with the information obtained thanks to the participation of health workers in actively reporting their health status.

This study is designed to look at the effectiveness of a new technology call Nanotechnology Biomarker Tagging (NBT) in detecting COVID-19 infection using breath samples of patients. Participation in this study is expected to take less than one month and will consist of a breath sample being taken by the research team, a cheek swab being taken by the research team, a questionnaire that will be completed by the participant with the help of the research teams, and a review of your medical record.

This study is a randomized, double-blinded, and placebo controlled phase Ⅱ clinical trial of the SARS-CoV-2 inactivated vaccine to evaluate the safety and immunogenicity of the experimental vaccine in healthy adults ⩾18 years.

This observational study is intended to evaluate the effect of disease modifying therapies on antibody responses to the mRNA-1273 vaccine (Moderna) for COVID-19. We hypothesize that the use of certain disease modifying therapies, particularly ocrelizumab, will mute and/or shorten the duration of humoral response to mRNA vaccines.

Effect of Covid-19 disease in clotting factors levels in hospitalized patients

The ongoing COVID-19 pandemics has put an overwhelming pressure on the healthcare systems of many European countries. Such a situation has potentially led to delayed and impaired access to appropriate treatment for patients affected by other severe, non-COVID-19-related conditions, including cardiovascular diseases. This resulted in a reported lower admission, but higher mortality rate for AMI patients. Such a situation might be explained by many factors, including unavailability of early reperfusion therapy and late hospital presentation of AMI patients due to a general anxiety related to the COVID-19 contagious risk of the hospital environment. As a matter of fact, during this year of pandemics, several case reports suggested a new, significant surge of post-AMI mechanical complications, sometimes describing patients admitted in too severe conditions to consider surgical repair a viable option, and therefore inevitably undergone an unfavorable outcome. Therefore, we decided to involve the large network of European centers already participating to the "Caution Study 1", in order to study the impact of COVID-19 pandemics on the outcomes, incidence and treatments of post-AMI mechanical complications.

The mortality rates associated with COVID-19 related ARDS (COVIDARDS) have varied from observational reports from around the world. This has ranged from 44% (28 day mortality) in the UK to 36% (28 day mortality from ICU admission) in Italian studies, to 32% (all-cause 28 day mortality) in Spain. Predictive models have identified risk factors for COVID-19 hospitalized patients' mortality to include male sex, obesity, age, obesity, comorbidities including chronic lung disease and hypertension, as well as biomarkers including high levels of D-Dimer, LDH and CRP. In addition, practice patterns, such as drugs that were administered, timing of mechanical ventilation and adherence to established lung protective ventilation protocols are known to be variable across sites and have changed over time. The investigators propose to analyze outcomes for patients with COVIDARDS within the NorthCARDS dataset (a dataset of over 1500 patients with COVID-19 related ARDS across the Northwell Health System in the NYC metropolitan region and Long Island, NY) to understand differences in hospital survival and in the time to liberation from mechanical ventilation, specifically looking at the associations between baseline patient factors, changes in biomarkers, respiratory function and hemodynamics over time, and treatments administered. The analyses will be based on three hypotheses: H.1. Worsening trajectories of: oxygenation index (OI), respiratory system compliance (C), and inflammatory markers will be associated with lower hospital survival. H.2. Higher duration of deep sedation and paralytics will be associated with greater time to liberation from mechanical ventilation. This risk will be increased in patients with worsening trajectories of OI, C, and inflammatory markers over time. H.3. Type of mechanical ventilator, specifically the time on portable mechanical ventilator, is associated with hospital mortality and with inability to liberate from mechanical ventilator despite controlling for risk factors of changes in OI, C and Inflammatory markers over time, and the use of paralytics and deep sedation.

Objective of the study: to investigate the effect of meglumine succinate solution on the dynamics of metabolic blood parameters and respiratory function of the lungs in intensive care patients with new coronavirus infection. An observational prospective study included 105 patients with a severe course of novel coronavirus infection
