Filter by:Prior findings in various viral respiratory diseases including SARS-CoV-related pneumonia suggest that convalescent plasma can reduce mortality, although formal proof of efficacy is still lacking. The investigators propose to evaluate intravenous administration of convalescent plasma (CP) obtained from COVID19 survivors in COVID19 patients who are in the medium stage. Supportive data exist for use of convalescent plasma in the treatment of COVID19 and other overwhelming viral illnesses. The study team wants to test the hypothesis that treatment with COVID19 CP will demonstrate salutary effects on COVID19 disease severity/duration, with the primary objective to reduce mortality. In addition, a major secondary objective to reduce the requirement for and/or duration of mechanical ventilation. This phase is to test the safety and efficacy of CP therapy.
Work attendance of more than 700 hospital workers was evaluated. The assessment of the number of medical services that were performed was based on monthly reports prepared for the national payer of health services.
A cohort study of women who deliver at select sites on randomly selected days in 2019 and 2020, and all confirmed COVID-19 infections among pregnant or immediately postpartum women in 2020. The study population includes approximately 24,400 deliveries on randomly selected days in 2019 and 2020, and an additional 1000-2100 confirmed COVID-19 infections among pregnant women or immediately postpartum.
The primary objectives are: - To assess the occurrence of adverse events of special interest (AESIs) in participants treated with repeated subcutaneous (SC) doses of REGN10933+REGN10987 compared to placebo - To assess the concentrations of REGN10933 and REGN10987 in serum over time after single and repeated SC administration The secondary objectives are: - To assess the safety and tolerability of repeated SC doses of REGN10933+REGN10987 compared to placebo - To assess attainment of target concentrations of REGN10933 and REGN10987 in serum after single and repeated SC administration - To assess the immunogenicity of REGN10933 and REGN10987
The proportion of asymptomatic carriers of SARS-CoV-2 remains elusive, so the potential benefit of systematic screening during the SARS-CoV-2-pandemic is controversial. We investigate the proportion of asymptomatic inpatients who were identified by systematic screening for SARS-CoV-2 upon hospital admission. Adult patients admitted to the University Hospital Basel from 01.04.-14.06.2020 were routinely tested for SARS-CoV-2 within 72 hours of admission by nasopharyngeal swabs. Each patient screened during the study period was retrospectively classified symptomatic or asymptomatic for COVID-19 based on medical chart review.
Hypothesis: Serum Vitamin D (25(OH)D) is significantly lower in severe versus non-severe COVID-19 infections and that this is a function of ethnicity. There is an association between vitamin D status and various cytokines (pro-inflammatory molecules). The primary objective of this research is to provide a snap shot of vitamin D status in patients from the South-East London area by age, sex, ethnicity and BMI and demonstrate ethnic differences in vitamin D status as well as its associations with severe vs non-severe COVID-19 infections. The secondary objective is to determine if there is an association between vitamin D status and various cytokines (pro-inflammatory molecules) and severity of disease.
A) Comparing the % of change in each clearances of pro-, and anti-inflammatory mediators (cytokine, chemokines and complement) in the COVID-19 patients treated with CytoSorb as compared to the same patient population who do not receive blood purification treatment. B) Testing the Cytokinetic model by measuring cytokines in the blood stream and in the BAL to see if you can create a reverse gradient allowing a massive passage of leucocyte from the blood toward the infected lungs.
CORONA is a retrospective, observational, one center study to investigate the clinical evolution (in terms of survival and thromboembolic complications) of patients on chronic treatment with anticoagulants or antiplatelet agents who are admitted to the hospital for COVID-19 compared with patients who do not receive anticoagulants or antiplatelet agents.
Drug studies often look at the effect one or two drugs have on a medical condition, and involve one company. There is currently an urgent need for one study to efficiently test multiple drugs from more than one company, in people who have tested positive for COVID-19 but who do not currently need hospitalization. This could help prevent disease progression to more serious symptoms and complications, and spread of COVID-19 in the community. This study looks at the safety and effectiveness of different drugs in treating COVID-19 in outpatients. In Phase II, participants in the study will be treated with either a study drug or with placebo. In protocol version 7.0, participants in Phase III of the study will be treated with either a study drug or active comparator drug. Participants assigned to the bamlanivimab agent/placebo arm and will have 28 days of intensive follow-up following study drug administration, followed by limited follow-up through 24 weeks in phase II and in phase III. All other investigational agents and their corresponding placebo arms will involve 28 days of intensive follow-up, followed by limited follow-up through 72 weeks in phase II and phase III. Additional study visits may be required, depending on the agent.
In patients with SARS-CoV-2 or bacterial infection admitted to the intensive care unit (ICU), the state of the intravascular volume, the characteristics of the blood volume components, and the development of a vascular leak is currently unknown. The relationship of these parameters with parameters of cardiac performance, lung edema and sublingual microcirculatory perfusion parameters have never been studied.
