Filter by:COVID-19 (Corona Virus Disease 2019) hospitalized patients evolution is marked by the risk of worsening of the respiratory system during the second week of the disease. To date, treatments are currently being evaluated and none of them have shown to be effective in the care of these patients. The use of convalescent plasma is a passive immunotherapy. It has often been used in respiratory virus epidemic situations (during the 1918 or 2009 influenza pandemic, or during SARS-CoV-1 or MERS-CoV pandemic). Effects reported in literature are in favour of a beneficial impact of transfusion of these plasma without serious adverse effects reported. PlasCoSSA is a randomized, controlled, triple-blinded, parallel clinical trial. This study tests the efficacy of convalescent plasma transfusion therapy in the early care of COVID-19 hospitalized patients outside intensive care units.
The most feared complication of COVID-19 infection is the occurrence of an acute respiratory distress syndrome (ARDS) that requires ICU admission and prolonged mechanical ventilation in more than 2% of the affected patients. Establishing the correct time to extubate mechanically ventilated patients is a crucial issue in the critical care practice. Delayed extubation has several consequences such as patient's mortality, health-care-related complications, neuropsychological adverse events. The aim of the INVICTUS study is to evaluate whether a CTUS-based MV weaning strategy could reduce the duration of mechanical ventilation of ARDS COVID-19 ICU patients by 72 hours, compared with usual medical care.
Blinded, multicenter, placebo-controlled, randomized clinical trial evaluating lopinavir/ritonavir vs placebo in early outpatient treatment of adults with COVID-19
The exceedingly high mortality rates of severe and critical COVID-19 warrant the identification and evaluation of novel therapies that could potentially mitigate the advanced disease manifestations. Based on preclinical data from this institution and others, the investigators hypothesize that PI3K inhibition with duvelisib could potentially quell aberrant hyperactivtation of the innate immune system, preferentially polarize macrophages, reduce pulmonary inflammation, and limit viral persistence, thereby improving patient outcomes.
Endothelial injury as a consequence of SARS-CoV-2 infection leads to a dysregulated host inflammatory response and activation of coagulation pathways. Macro- and micro-vascular thrombosis may contribute to morbidity, organ failure, and death. Therapeutic anticoagulation with heparin may improve clinical outcomes in patients with COVID-19 through anti-thrombotic, anti-inflammatory, and anti-viral activities of heparins. This pragmatic, Bayesian adaptive randomized controlled trial will determine whether therapeutic anticoagulation with heparin (subcutaneous low molecular weight heparin or intravenous unfractionated heparin) versus usual care reduces the need for intubation or death in hospitalized patients with COVID-19. The trial uses an adaptive design which was chosen to overcome limitations in available data to inform a priori estimation of event rates and possible effect sizes. The adaptive design also includes response-adaptive randomization based on baseline D-dimer level, probing for differential efficacy across subgroups defined based on initial D-dimer level. This Bayesian adaptive randomized trial will stop at a conclusion 1) when the posterior probability that the proportional odds ratio is greater than 1.0 reaches 99% (definition of benefit); 2) when the posterior probability that the proportional odds ratio is greater than 1.2 is less than 10% (definition of futility) or; 3) when the posterior probability that the proportional odds ratio is less than 1.0 is greater than 90% (definition of harm). The trial will enroll a maximum of 3,000 patients, although in many simulations the trial may require fewer patients. The trial is strategically aligned with the international REMAP-CAP/COVID platform trial to accelerate evidence generation.
This is a single-site prospective study to evaluate the diagnostic performance of the investigational SeptiScan System for patients presenting to the Emergency Department with signs or suspicion of COVID-19 or other infectious respiratory diseases.
This expanded access program will provide access to COVID-19 convalescent plasma 150 or more individuals with moderate to severe or life-threatening manifestations of COVID-19, or documented to be at high risk of developing such manifestations at participating hospitals in Colorado.COVID-19 convalescent plasma is the liquid part of blood that is collected from patients who have recovered from COVID-19. Convalescent plasma collected from individuals who have recovered from COVID-19 contains antibodies to SARS-CoV-2. Preliminary evidence and data collected during other respiratory virus outbreaks (including the 2003 SARS-CoV-1 epidemic, the 2009-2010 H1N1 influenza virus pandemic, and the 2012 MERS-CoV epidemic) suggest that the antibodies in convalescent plasma may be effective in fighting the infection.
The outbreak of the coronavirus disease 2019 (COVID-19), first merged in China in December 2019, is now becoming a Public Health Emergency, recently confirmed as a pandemic disease by the World Health Organization. In particular, since February 2020, a rapidly growing number of cases has been identified in Italy. The clinical picture of ranges from asymptomatic cases, mild upper respiratory tract infections to severe pneumonia with respiratory failure and death. In most severe cases, COVID-19 disease may be complicated by acute respiratory distress syndrome (ARDS), septic shock and multiorgan failure. It results fundamental to early identify those subjects who rapidly may worsen their clinical status, often requiring an intensive care unit (ICU) admission. It has been showed that, mainly in more severe forms of SARS-Cov-2 disease, there is the development of an hyperinflammatory status resembling a cytokine storm syndrome, as already reported in SARS patients. A recent study by Haung et al. reported that patients with COVID-19 infection showed high amounts of IL1B, IFN-gamma, IP10 and MCP1, probably linked to activated T-helper1 (Th1) cell responses. Those requiring ICU admission had higher levels of cytokines than those subjects not requiring ICU admission, thus suggesting that cytokine storm was associated with disease severity. A similarity between cytokine profile of COVID-19 disease and secondary haemophagocytic syndrome (sHLH) has been reported. Therefore, it was suggested to screen all patients with severe COVID-19 infection both for hyperinflammatory markers (like ferritin), and the HScore commonly used to generate a probability for diagnosis of sHLH (8), which includes some laboratory parameters like triglycerides, fibrinogen, ferritin, serum aspartate aminostransferase. Based on our experience on patients affected by pneumonia from Covid19, we have observed that those subjects with a more severe prognosis might have some predictive markers. We intend to verify if these markers can identify those subjects with Covid19 infection who need a more intensive therapy and to find a prognosis score.
This study (EMPACTA) will a) evaluate the efficacy and safety of tocilizumab (TCZ) compared with a placebo in combination with standard of care (SOC) in hospitalized participants with COVID-19 pneumonia, and b) include an optional long-term extension for eligible participants to explore the long-term sequelae of resolved COVID-19 pneumonia.
COVID-19 presents a significant and unprecedented public health challenge which is placing enormous strain on global health services. In London, we have seen exponential growth in the number of cases of COVID-19 and significant public concern which has been felt across healthcare systems. The London Ambulance Service NHS Trust (LAS) is consistently experiencing its busiest days on record and is at the frontline of the response to COVID-19. Whilst knowledge of the progression and clinical manifestations of the disease is improving, there is a lack of knowledge of how COVID-19 patients access and use emergency medical services (EMS), and what interventions are required to manage these patients in their prehospital phase. This knowledge is vital for the planning and delivery of EMS care as the pandemic develops. Similarly, although evidence is emerging from the in-hospital setting about the toll of caring for COVID-19 patients, little is known about the effects on the mental wellbeing of EMS staff who are faced with considerable uncertainty when triaging, assessing and treating patients with limited access to support, resources or testing. This mixed method study will have two parallel work packages: Work package one will aim to rapidly improve knowledge of how patients with COVID-19 access and use EMS services. Patient records will be reviewed for patients who present to LAS and go on to receive a diagnosis of COVID-19. Characteristics and trends in these presentations will be reported to inform the ongoing planning and delivery of EMS care to these patients. Work package two will explore, through questionnaires and interviews, the personal and professional impacts of triaging, assessing and treating patients who receive a diagnosis of COVID-19. This will inform the ongoing support requirements for EMS staff and provide evidence to support the planning for future pandemic disease outbreaks.
