Filter by:Background: A novel Coronavirus (SARS-CoV-2) described in late 2019 in Wuhan, China, has led to a pandemic and to a specific coronavirus-related disease (COVID-19), which is mainly characterized by a respiratory involvement. While researching for a vaccine has been started, effective therapeutic solutions are urgently needed to face this threaten. The renin-angiotensin system (RAS) has a relevant role in COVID-19, as the virus will enter host 's cells via the angiotensin-converting enzyme 2 (ACE2); RAS disequilibrium might also play a key role in the modulation of the inflammatory response that characterizes the lung involvement. Angiotensin-(1-7) is a peptide that is downregulated in COVID-19 patient and it may potentially improve respiratory function in this setting. Methods/Design: The Investigators describe herein the methodology of a randomized, controlled, adaptive Phase II/Phase III trial to test the safety, efficacy and clinical impact of the infusion of angiotensin-(1-7) in COVID-19 patients with respiratory failure requiring mechanical ventilation. A first phase of the study, including a limited number of patients (n=20), will serve to confirm the safety of the study drug, by observing the number of the severe adverse events. In a second phase, the enrollment will continue to investigate the primary endpoint of the study (i.e. number of days where the patient is alive and not on mechanical ventilation up to day 28) to evaluate the efficacy and the clinical impact of this drug. Secondary outcomes will include the hospital length of stay, ICU length of stay, ICU and hospital mortality, time to weaning from mechanical ventilation, reintubation rate, secondary infections, needs for vasopressors, PaO2/FiO2 changes, incidence of deep vein thrombosis, changes in inflammatory markers, angiotensins plasmatic levels and changes in radiological findings. The estimated sample size to demonstrate a reduction in the primary outcome from a median of 14 to 11 days is 56 patients, 60 including a dropout rate of 3% (i.e. 30 per group), but a preplanned recalculation of the study sample size is previewed after the enrollment of 30 patients. Expected outcomes/Discussion: This controlled trial will assess the efficacy, safety and clinical impact of the Angiotensin-(1-7) infusion in a cohort of COVID-19 patients requiring mechanical ventilation. The results of this trial may provide useful information for the management of this disease.
Convalescent plasma (CP) has been used in recent years as an empirical treatment strategy when there is no vaccine or treatment available for infectious diseases. In the latest viral epidemics, such as the Ebola outbreak in West Africa in 2014, the World Health Organization issued a document outlining a protocol for the use of whole blood or plasma collected from patients who have recovered from the Ebola virus disease by transfusion to empirically treat local infectious outbreaks.
This is an observational study of patients with COVID-19 designed to specifically address important clinical questions that remain incompletely answered for coronavirus disease 2019.
This study aims to 1) observe the course of pain, 2) mental status, and 3) possible effect of a behavioral intervention delivered via an automated mobile phone messaging robot in patients were indicated and/or scheduled to undergo joint replacement but have been cancelled or delayed due to the COVID-19 crisis.
As of February 17th, 2020, China has 70635 confirmed cases of coronavirus disease 2019 (COVID-19), including 1772 deaths. Human-to-human spread of virus via respiratory droplets is currently considered to be the main route of transmission. The number of patients increased rapidly but the impact factors of clinical outcomes among hospitalized patients are still unclear.
Coronavirus 2019 (COVID-19) is a respiratory tropism virus transmitted through droplets emitted into the environment of infected persons. The symptoms can be extremely varied and the course can range from spontaneous healing without sequelae to death. Currently, the diagnosis of certainty for resuscitation patients (by definition "severe") is based on searching for a fragment of virus genetic material within the epithelial cells of the respiratory tree, up and/or down, by PCR. It is to be expected that the epidemic peak will make it difficult (if not impossible) to respect the stereotypical path that is currently in place, due to the lack of space in the specific unit. This will require optimization of care pathways and use of the specific sectors. It is therefore necessary to define the simple criteria, available from the moment patients are admitted, to predict the result of the COVID-19 PCR.
COVID-19 (also known as Coronavirus) originated in the Wuhan China and has since spread to at least 159 countries around the world. It was declared a pandemic by the World health organisation on the 11th of March 2020. The cases in the United Kingdom continue to increase exponentially with up to 5 683 people diagnosed as on the 22nd of March 2020. It is estimated that 1 in 5 people diagnosed will require hospital admission and 1 in 20 intensive care treatment. By developing and improving diagnostic testing, we can accurately diagnose infected cases to triage appropriate treatments, identify individuals for quarantine in order to prevent transmission and obtain information regarding patient's immune systems. At present, the diagnostic test is a highly specific method of genetic amplification called 'Reverse Transcription - Polymerase Chain Reaction' or RT-PCR, which allows detection of very small amounts of genetic mutations caused by the COVID-19 virus. However, this method must be completed in highly specialised facilities, which are few and far between, increasing time to diagnosis (currently 48-72 hours), increasing exposure to non-infected individuals, and overburdening the analysing facilities. The ideal solution is a point of care (POC) test that can give results immediately. This study aims to harness the point of care technology of the SAMBA II device (Diagnostics for the Real World Ltd.), which is a CE-marked device that has been used with success in the identification of Human Immunodeficiency Virus (HIV), by amplifying genetic material without the need to increase and decrease temperatures during the amplification process. In the COVIDx study, 200 patients meeting the Public Health England's (PHE) inpatient definition of having suspected COVID-19 will be approached, consented and a sample from throat and nasal swab (combined) or tracheal fluid taken and tested using the SAMBA II method. A combination of the standard PHE RT-PCR and an additional validated laboratory PCR technique will be used as a control in line with standard clinical practice. Patients will undergo an additional serum tests on existing samples as made available after routine clinical assessments to monitor antibody response. Patients will be followed for clinical outcomes at 28 days post-admission.
A new human coronavirus responsible for pneumonia, SARS-CoV-2, emerged in China in December 2019 and has spread rapidly. COVID-19, the disease caused by this virus, has a very polymorphous clinical presentation, which ranges from upper respiratory tract infections to acute respiratory distress syndrome. It may appear serious straightaway or may evolve in two stages, with a worsening 7 to 10 days after the first clinical signs, potentially linked to a cytokine storm and accompanied by a high risk of thrombosis. The global mortality rate of COVID-19 is between 3% and 4%, with severe forms being more frequent among older patients. Management is symptomatic as no antiviral treatment has demonstrated any clinical benefit in this condition. Hydroxychloroquine is a derivative of chloroquine commonly used in some autoimmune diseases, such as systemic lupus erythematosus. It is active in vitro in cellular models of infection by many viruses such as HIV, hepatitis C or SARS-CoV. However, its interest in viral infections in humans has not been demonstrated. Very recently, a preliminary uncontrolled study evaluated the effect of hydroxychloroquine on viral shedding in subjects with COVID-19. Among 20 patients treated with hydroxychloroquine at a dose of 600 mg per day, the percentage of patients with detectable SARS-CoV-2 RNA in the nasopharynx decreased from 100% at inclusion (start of treatment) to 43% six days later. In comparison, 15 of 16 untreated patients had a positive RT-PCR six days after inclusion. Furthermore, hydroxychloroquine has immunomodulating and anti-inflammatory properties, which could theoretically prevent or limit secondary worsening. The research hypothesis is that treatment with hydroxychloroquine improves prognosis and reduces the risk of death or use for invasive ventilation in patients with COVID-19.
Researchers are trying to assess the treatment potential and safety of anti-SARS-CoV-2 convalescent plasma in patients with acute respiratory symptoms with confirmed COVID-19.
COVID-19 (Coronavirus Disease-2019) is a life-threatening infectious disease caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that appeared in December 2019 in the Wuhan district. COVID-19 has since affected more than 150 countries across the world and especially France. The first epidemiological data, mostly from Chinese studies, indicate that diabetes is one of the most common comorbidities, with high blood pressure, in patients with COVID-19. Moreover, the presence of diabetes at admission would be a risk factor for both ICU hospitalization and death. Nevertheless, specific data on people with diabetes and COVID-19 are fragmentary, justifying the achievement of a dedicated prospective observational study. The French nationwide CORONADO study aims to specifically describe the phenotypic characteristics of patients with diabetes admitted to hospital with COVID-19 infection. Particular attention will be devoted to glycemic control at admission (i.e. the level of HbA1c), the diabetic complications, as well as anti-diabetic and antihypertensive therapies. This study will provide answers to caregivers and patients with diabetes regarding the risk factors related to diabetes for COVID-19 prognosis. This pilot study will be used for the development of new studies and for the establishment of recommendations for the cost of care in patients with diabetes and COVID-19.
