Filter by:There are currently no approved therapies for patients with coronavirus disease (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Infusion of ascorbic acid (vitamin C) has been shown to increase activity of lymphocytes, which are a crucial component of the body's defense against viral disease progression and adaptive immunity. Ascorbic acid infusion has been shown to be a safe treatment for patients suffering from sepsis and certain types of cancer. This study is designed to evaluate the safety and efficacy of ascorbic acid in the form of sequential I.V. infusions (Ascor®) for patients with suspected COVID-19 who are unlikely to require mechanical ventilation within 24 hours of study intervention.
We propose a 3-arm RCT to determine the efficacy of hydroxychloroquine or azithromycin in treating mild to moderate COVID-19 among Veterans in the outpatient setting.
Mental health disorders are common during pregnancy and the postnatal period, and can have serious adverse effects on the well-being of woman and child. Every tenth woman has depressive symptoms and 5% suffer major depression during pregnancy. The consequences for global mental health due to the novel coronavirus disease, COVID-19, are likely to be significant and may have long-term impact on the global burden of disease. Pregnant women may be particularly vulnerable due to partial immune suppression. Besides physical vulnerability, the women could be at increased risk of mental health problems, such as anxiety, depression, and post-traumatic stress disorder (PTSD), due to social distancing leading to less support from the family and friends, and in some cases, partners not being allowed to be present during prenatal visits, labor and delivery. Furthermore, many pregnant women may feel insecure and worried about the effect of COVID-19 on their unborn child, if the women get infected during pregnancy. Today, young urban women are used to utilizing internet services frequently and efficiently. Therefore, providing mental health support to pregnant women via web-based support may be effective in ameliorating their anxiety/depression and reduce the risk of serious mental health disorders leading to improved maternal and perinatal outcomes.
Since December 2019, a new agent, the coronavirus SARS-Cov-2, has spread from China to the rest of the world causing an international epidemic of respiratory diseases called COVID-19. Oise was one of the first clusters in France, with more than 4,000 confirmed cases. A significant proportion (80%) of patients with COVID-19 are ambulatory. However, few data are available for this particular population in France. Thus, few clear recommendations are available. We propose to conduct a large cohort of observation of suspected or confirmed COVID-19 patients on an ambulatory basis in the Oise region. This observatory will make it possible to describe the epidemiological characteristics and initial management of COVID-19 patients and to identify early severity factors.
The global pandemic of novel coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) began in Wuhan, China, in December 2019, and has since spread worldwide.1 As of April 14, 2020, there have been more than 1.5 million reported cases and 124 000 deaths in more than 200 countries. A recent open-label nonrandomized French study reporte that addition of azithromycin to hydroxychloroquine in 6 patients resulted in numerically superior viral clearance (6/6, 100%) compared with hydroxychloroquine monotherapy (8/14, 57%) or control (2/16, 12.5%). Azithromycin alone has never been tested, whereas azithromycin has immunomodulating and anti-inflammatory properties that could theoretically prevent or limit secondary worsening. Our hypothesis is that azithromycin combined with amoxicillin/clavulanate will be superior to amoxicillin/clavulanate alone to obtain viral clearance at Day 6 in COVID-19 patients with pneumonia and hospitalized in a non-intensive care unit ward.
This is an expanded access treatment protocol to treat up to 100 patients with severe or life-threatening, laboratory confirmed COVID-19 with COVID-19 convalescent plasma.
Emergent experimental and anecdotal evidence has indicated that critically ill COVID-19 patients demonstrate two patient sub-types (called phenotypes). In one group the disease progresses slowly and patients have a low potential of developing mild respiratory failure, but in the other group, an exaggerated immune response (hyper-inflammation/cytokine storm) may be linked to the onset of precipitous respiratory failure, termed acute respiratory distress syndrome. This syndrome is responsible for a large portion of COVID-19 associated mortality. Thus, determining links between hyper-inflammation and acute respiratory distress syndrome in COVID-19 patients is of immediate importance. Blood samples will undergo a number of analyses to help us to understand as much as possible about COVID-19. We will also study any differences in physiologic and cytokine levels before and after patients are treated with immunomodulatory therapies as part of clinical care in COVID-19 patients.
This is a prospective adaptive cohort study of St. Jude employees to determine the rate of SARS-CoV-2 infections that are asymptomatic and to evaluate immunological responses to SARS-CoV-2 infection. Primary Objectives - To estimate the proportion of asymptomatic infection with SARS-CoV-2 infection in a population of SARS-CoV-2-naïve adult St. Jude employees - To comprehensively map CD4 and CD8 T cell epitopes and response magnitudes to SARS-CoV-2 infection in a population of SARS-CoV-2-naïve adult St. Jude employees who acquire SARS-CoV-2 infection - To measure changes in the CD4 and CD8 response magnitude and function to SARS-CoV-2 infection and/or vaccination in a population of St. Jude employees for up to 48 months after infection and/or vaccination. Secondary Objectives - To establish seroprevalence of SARS-CoV-2-specific antibodies at baseline, and identify the rate of seroconversion to SARS-CoV-2 in a population of presumably naïve adult St. Jude employees - To identify features of T cell responses at baseline and during SARS-CoV-2 infection that are associated with protection against symptomatic or severe COVID-19 disease in a population of adult St. Jude employees - To identify risk factors for long-term protection against COVID-19 in a population of adult St. Jude employees - To evaluate changes in antibody responses to SARS-CoV-2 in a population of St. Jude employees for up to 48 months after SARS-CoV-2 infection and/or vaccination. - To evaluate the saliva antibody and cytokine response to SARS-CoV-2 infection and/or vaccination and identify characteristics that predict protection from subsequent SARS-CoV-2 infection among a population of St. Jude employees followed for up to 48 months after SARS-CoV-2 infection and/or vaccination. - To measure changes in saliva antibody responses to SARS-CoV-2 for up to 48 months after SARS-CoV-2 infection and/or vaccination. Exploratory Objectives - To establish additional immunological features including host immune or receptor polymorphisms associated with response to SARS-CoV-2 infection - To explore SARS-CoV-2 diversity and specific features in a circumscribed population - To describe the presence, characteristics, and proportion of short-term re-infection - To determine if an association between SARS-CoV-2 viral load in nasal swab specimens and COVID-19 symptoms can be identified in a population of adult St. Jude employees who acquire SARS-CoV-2 - To explore the laboratory and clinical response to SARS-CoV-2 vaccine in a population of adult St. Jude employees with and without a history of SARS-CoV-2 infection
In December 2019, an outbreak of pneumonia of initially unknown cause was detected in Wuhan (Hubei, China), and it was quickly determined that it was caused by a new coronavirus, that is, the SARS-CoV- 2 virus, causing the disease called COVID-19. Since then, the outbreak has spread to 5 continents, affecting 185 countries or regions, with more than 2,500,000 confirmed cases as of April 21, 2020. Ecuador, the 9th country according to territorial extension, and the 7th according to the number of inhabitants in South America, is the 4th country with the highest number of cases in that region of the world, only behind Brazil, Peru and Chile. According to data from the Ministry of Public Health (MSP) of Ecuador, as of April 20, 2020, the National Institute for Public Health Research (INSPI) has registered 33,279 samples, of which 10,128 are positive for SARS-CoV-2. By far, the province of Guayas where Guayaquil is located, the main city in terms of number of inhabitants of the country, is the region with the highest number of affected, with 6921 confirmed cases and 6274 with suspicion. Given the importance of this infection, the severity in some cases, its rapid distribution, and the differences in the Ecuadorian population with respect to the other countries where infected patients have been reported, the investigators consider that an updated analysis of cases, taking as a reference, patients seen in various hospitals of the city of Guayaquil can help identify the clinical characteristics and severity of the disease.
This is a multi-center prospective study that aims to investigate the clinical and immunologic impact of SARS-CoV-2 infection in pregnant women and neonates. The goal is to recruit 200 SARS-CoV-2 infected pregnant women starting at 24 weeks of gestation in a neonatal network of 45.000 birth a year. Clinical data will be collected from women and neonates. Upper airways samples will be obtained from both for bio-markers investigation. Finally, maternal and umbilical cord serum and human milk will be obtained for antibody assessment.
