Filter by:To compare various treatments provided to positive COVID-19 patients at locations across the OSF Ministry. Provide the opportunity to compare the effectiveness of various treatments and treatment timelines provided to specific cohorts of patients that have the potential to impact future treatment plans for COVID-19 patients and/or future research hypotheses.
SARS-CoV-2 induces over-production of inflammatory cytokines, and especially interleukin-6 (IL-6). The apparently strong association between blood levels of inflammaory cytokines and SARS-CoV-2 disease severity has led clinicians to evaluate the administration of steroids or anti-IL-6 antagonists in severely ill patients. As of this day, biomarkers capable of predicting clinical disease progression in Covid-19 patients with mild-to-moderate symptoms have not yet been formally identified. Identifying such markers and evaluating their predictive value may be exploited to guide patient care management, and as such forms the core objective of this proposal. Because of strong inter-individual variations in the ability of innate immune cells to produce cytokines, the hypothesis formulate and intend to test is that innate IL-6 responsiveness varies between recently infected Covid-19 patients and could predict disease outcome. To test this hypothesis, the investigator propose to follow recently infected kidney transplant patients with moderate Covid-19 symptoms. These patients stand a higher risk to progress to severe disease. The staff plan to collect a blood sample in these patients using a system whereby ex vivo cytokine production is initiated in the very same blood collection tube without prior separation and centrifugation, thus reducing labour and operator bias. After incubation with or without known innate immune stimuli, the cell-free phase from each collection-culture tube will be assayed for IL-6 content. Associations between IL-6 content and disease outcome (encephalopathy, transfer to acute care or death) will be determined in 115 Covid-19 kidney transplant patients with moderate symptoms followed in 9 centers.
Prophylactic treatment in cancer patients undergoing antineoplastic therapy during the COVID-19 pandemic.
This is a compassionate use, proof of concept, phase IIb, prospective, interventional, pilot study in which the investigators will evaluate the effects of compassionate-use treatment with IV tirofiban 25 mcg/kg, associated with acetylsalicylic acid IV, clopidogrel PO and fondaparinux 2.5 mg s/c, in patients affected by severe respiratory failure in Covid-19 associated pneumonia who underwent treatment with continuous positive airway pressure (CPAP).
This concerns a single-center prospective interventional cohort study. Laboratory-confirmed COVID-19 patients will be asked to donate blood at at least two different timepoints. This will allow us to investigate T and B cell evolutions during the course of infection and recovery. The expected duration of the study is four months or the total duration of the SARS-CoV-2 circulation in Belgium (whichever is shortest).
The novel coronavirus (SARS-CoV-2) has spread all around the world and testing has posed a challenge globally. Health care providers are highly exposed and are an important group to test. On top of these concerns, health care workers are also stressed by the needs on responders in the COVID-19 crisis. The investigators will look at different ways to measure how common COVID-19 is among health care workers, how common is the presence of antibodies by serological tests (also known as serostatus). The investigators will describe health worker mental and emotional well-being and their coping strategies in their institutional settings. Lastly, the investigators will describe how knowing serostatus can affect individuals' mental and emotional well-being and how to cope in the midst of the COVID-19 response. This will help to how to better test and help healthcare workers in the COVID-19 pandemic and prepare for possible future outbreaks.
Purpose: To determine the number of asymptomatic individuals who have antibodies to SARS-CoV-2, the virus which causes COVID-19
Coronavirus COVID-19 is an emerging virus also called Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2). Eighty percent of patients are poor or asymptomatic. However, there are major respiratory complications for some patients, requiring intensive care hospitalization and possibly leading to death in 5% of cases. One of the hypotheses put forward is that much of the pathophysiology is due to endothelial dysfunction associated with disseminated intravascular coagulation. The covid-19 pathology could induce coagulation impairment as observed during sepsis. An increase in D-dimer levels during covid-19 disease is itself associated with excess mortality. While D-dimers are highly sensitive, they are not specific for clotting activity. They may be increased in many other circumstances, particularly in inflammation. On the other hand, the infection stimulates the release of extracellular vesicles. These vesicles, of multiple cellular origin, are an actor of vascular homeostasis, and participate in the state of hyperactivation of coagulation. They have a major role in the prothrombotic state and the development of coagulopathy associated with sepsis. The aim of our monocentric prospective study would be to study early and more specific markers of hypercoagulability and markers of routine endothelial dysfunction, as soon as the patient is hospitalized, in order to predict the risk of hospitalization in intensive care.
Prospective registry for multimodal assessment of neuromuscular pathology associated with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, enrolling consecutive patients with corona virus disease 2019 (Covid-19), who are admitted to the intensive care unit of the department of anesthesiology and intensive care medicine, or the department of neurology at Tübingen University Hospital.
The infectious disease COVID-19, caused by coronavirus SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2), has been declared a pandemic and an international healthcare emergency by the World Health Organization (WHO). It has spread across the globe, overwhelming healthcare systems by causing high rates of critical illness. Mortality from COVID-19 exceeds 4%, with older people with comorbidities being extremely vulnerable. It is expected that between 50-80% of the world's population may contract SARS-CoV-2 over the next two years. It is expected that the outcomes will be potentially worse in Africa, because firstly, there is a limited workforce, and secondly there are limited intensive care facilities and critical care resources across Africa to provide sufficient care. It is important therefore to establish what resources, comorbidities and interventions are potentially associated with either mortality or survival in patients with COVID-19 who are referred for critical care in Africa. Rapid dissemination of these findings may help mitigate mortality from COVID-19 in critical care patients in Africa. These points provide the rationale for the African COVID-19 Critical Care Outcomes Study (ACCCOS).
