Filter by:CovidSurg will capture real-world international data, to determine 30-day mortality in patients with COVID-19 infection who undergo surgery. This shared international experience will inform the management of this complex group of patients who undergo surgery throughout the COVID-19 pandemic, ultimately improving their clinical care.
This is a multi-center, randomized controlled, superiority, open label trial. The objective of this trial is to evaluate the efficacy of HCQ in patients with newly diagnosed COVID-19 who have mild to moderate disease or at risk for complications. We aim to demonstrate decrease in progression to severe pneumonia and hospital related complications among patients who are treated with HCQ compared to patients who are not.
Different studies showed that ascorbic acid (vitaminC) positively affects the development and maturation of T-lymphocytes, in particular NK (natural Killer) cells involved in the immune response to viral agents. It also contributes to the inhibition of ROS production and to the remodulation of the cytokine network typical of systemic inflammatory syndrome. Recent studies have also demonstrated the effectiveness of vitamin C administration in terms of reducing mortality, in patients with sepsis hospitalized in intensive care wards. Given this background, in the light of the current COVID-19 emergency, since the investigators cannot carry out a randomized controlled trial, it is their intention to conduct a study in the cohort of hospitalized patients with covid-19 pneumonia, administering 10 gr of vitamin C intravenously in addition to conventional therapy.
The novel coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS CoV-2) has been discovered recently in December 2019 from wuhan city in China to spread in more than 40 countries allover the world. This disease has gain the attention of all nations after it has been stated as a pandemic by the World Health Organization (WHO) in March 12, 2020. Currently no treatment has been proved to be efficient in the treatment of infected patients by COVID-19. Natural honey has been demonstrated as potent antimicrobial in many research investigations and has been considered a good alternative for antiviral drugs for the treatment of some viral infections. The investigators aim to study the efficacy of natural honey in the treatment of COVID-19 patients in this randomized , multicenter, controlled trial, comparing honey in one arm to standard care in the other arm.
In December 2019, a new type of pneumonia, COVID-2019 outbroke in Wuhan ,China, and currently the infected has been reported in more than at least 75 countries. Patients with severe COVID-19 have rapid disease progression and high mortality rate. This may attribute to the excessive immune response caused by cytokine storm. Strategies based on anti-virus drugs and treatments against symptoms have now been employed. However, these managements can't effectively treat the lethal lung injury and uncontrolled immune responses, especially in the elderly with severe COVID-19. Traditional Chinese Medicine (TCM), which treats the disease from anther perspective, has achieved satisfactory results. National Health Commission of China released a series of policies to enhance the administration of TCM prescriptions. This study is aimed to evaluate the efficacy and safety of Traditional Chinese Medicine as an adjuvant treatment for severe COVID-19.
COVID-19 pandemic threatens patients, societies and healthcare systems around the world. The host immunity determines the progress of the disease and its lethality. The associated cytokine storm mainly affects the lungs; leading to acute lung injury with variable degrees. Modulation of cytokine production using Immunonutrition is a novel concept that has been applied to other diseases. Using specific nutrients such as n3- fatty acids and antioxidant vitamins in extraordinary doses modulate the host immune response and ameliorate the cytokine storm associated with viral diseases such as COVID-19. In this proposal, we will conduct a prospective double-blinded controlled trial for 14 days on 30 SARS-CoV-2 positive cases. The participant will be randomly assigned to two groups (n=20/each); intervention (IG) and placebo (PG) groups. The IG group will be provided with an anti-inflammatory and antioxidant oral supplement (OS) on a daily basis, while the PG will be given an isocaloric placebo. Basal and weekly nutritional screening, as well as recording of anthropometric, clinical and biochemical parameters, will be done. The main biochemical parameters include serum ferritin level, cytokine storm parameters (interleukin-6, Tumor necrosis factor-α, and monocyte chemoattractant protein 1), C-reactive protein, total leukocyte count, differential lymphocytic count and neutrophil to lymphocyte ratio. It is expected that the anti-inflammatory-antioxidant OS might help in the reduction of the COVID-19 severity with more preservation of the nutritional status of infected cases.
The study use UK based linked electronic health records from the Clinical Research Datalink (CALIBER) of 5.6 million individuals to conduct a matched case-control study to investigate the incidence of influenza in individuals prescribed ACEI compared to those not prescribed ACEI.
Cytokines and chemokines are thought to play an important role in immunity and immunopathology during virus infections [3]. Patients with severe COVID-19 have higher serum levels of pro-inflammatory cytokines (TNF-α, IL-1 and IL-6) and chemokines (IL-8) compared to individuals with mild disease or healthy controls, similar to patients with SARS or MERS . The change of laboratory parameters, including elevated serum cytokine, chemokine levels, and increased NLR in infected patients are correlated with the severity of the disease and adverse outcome, suggesting a possible role for hyper-inflammatory responses in COVID-19 pathogenesis. Importantly, previous studies showed that viroporin E, a component of SARS-associated coronavirus (SARS-CoV), forms Ca2C-permeable ion channels and activates the NLRP3 inflammasome. In addition, another viroporin 3a was found to induce NLRP3 inflammasome activation . The mechanisms are unclear. Colchicine, an old drug used in auto-inflammatory disorders (i.e., Familiar Mediterranean Fever and Bechet disease) and in gout, counteracts the assembly of the NLRP3 inflammasome, thereby reducing the release of IL-1b and an array of other interleukins, including IL-6, that are formed in response to danger signals. Recently, colchicine has been successfully used in two cases of life-threatening post-transplant capillary leak syndrome. These patients had required mechanically ventilation for weeks and hemodialysis, before receiving colchicine, which abruptly restored normal respiratory function and diuresis over 48 hrs [4].
Growing evidences are showing the usefulness of lung ultrasound in patients with COVID-19. Sars-CoV-2 has now spread in almost every country in the world. In this study, the investigators share their experience and propose a standardized approach in order to optimize the use of lung ultrasound in covid-19 patients. The investigators focus on equipment, procedure, classification and data-sharing.
In December 2019, a pneumonia due to a novel coronavirus (SARS-CoV-2) emerged in the city of Wuhan, in China. In a few weeks, the number of confirmed cases of SARS-CoV-2 infection has dramatically increased, with almost 150'000 cases and more than 6'000 reported deaths on March, 16th 2020. Little is known on the rate of human-to-human transmission of this new coronavirus SARS-CoV-2 in the community and within the hospital. Depending on the country, contact subjects considered to be at high or moderate risk of SARS-CoV-2 are, either isolated at home for a period of time defined by the health authorities or, on the contrary, continue their professional activity on the condition that they adopt measures to prevent transmission to those around them. In most European countries, healthcare workers adopt this second option. In all cases, it is most often recommended that contact persons monitor their state of health and communicate it to the persons dedicated to this action. Whether such subjects become spreaders of the virus is not known, nor is the proportion of viral spreader who will develop a symptomatic infection. In this study, we aim to evaluate the virological and clinical outcomes of subjects following a contact at high/moderate risk of SARS-CoV-2 acquisition, in community-subjects and/or healthcare workers. The study population is represented by all subjects who had a contact with laboratory-confirmed SARS-CoV-2 cases and whose contact was considered to be at high/moderate risk of SARS-CoV-2 acquisition. This include both children and adult subjects, subject without social security, and healthcare workers.
