This study is meant to assess the lung mechanics in SARS-CoV-2 induced acute respiratory failure. A precise characterisation of lung mechanics and heart-lung-interactions might allow a better understanding of SARS-CoV-2 induced acute respiratory failure and thus lead to better mechanical ventilation strategies. This monocentric, observational study of critically ill COVID-19 patients in the ICU, will employ impedance tomography, right-heart catheterization, oesophageal pressure measurements, indirect calorimetry as well as classic mechanical ventilation parameters to characterise the mechanical characteristics of the lung as well as the heart-lung interactions in SARS-CoV-2 induced acute respiratory failure.
The hypothesis is that from a cluster defined by a confirmed positive case of COVID-19 and its contact cases, it is possible to study the different expressions and clinical evolutions of COVID-19 infection and to explore the biological profiles related to the observed clinical history. Certain biological determinants (virological, immunological, microbological or gentic) could indeed be correlated with the clinical presentation and/or be useful for personalized care. The main objective is to study the relationship between the biological profiles observed and the clinical evolutions within the same cluster of transmission of the coronavirus SARS-CoV-2 (positive COVID-19 cases and contact subjects).
This is an open-label, expanded access study of exebacase used in addition to antistaphylococcal antibiotics in adult patients with persistent methicillin-resistant Staphylococcus aureus (MRSA) bloodstream infections (BSI), including right-sided endocarditis (R-IE), who are hospitalized with coronavirus disease 2019 (COVID-19). Patients with left-sided endocarditis (L-IE) are excluded. Patients will receive a single dose of exebacase. Patients will continue to receive antistaphylococcal antibiotics as prescribed by the treating physician. Exebacase Phase 3 study sites (Study CF-301-105) may participate in this Expanded Access study (Study CF-301-107). Exebacase, a direct lytic agent, is an entirely new treatment modality against S. aureus. Exebacase is a recombinantly-produced, purified cell wall hydrolase enzyme that results in rapid bacteriolysis, potent biofilm eradication, synergy with antibiotics, low propensity for resistance, and the potential to suppress antibiotic resistance when used together with antibiotics. Exebacase represents a first-in-field, first-in-class treatment with the potential to improve clinical outcome when used in addition to standard-of-care antibiotics to treat S. aureus BSI including IE.
Phase 1: 25 patients with a PCR-based diagnosis of Covid-19 will be be included to give 500 microliters of saliva and a 3 ml sample of blood for proteomic analysis; a drop of blood will also be put in a device connected to a silica matrix to perform spectrometric analyses. 25 patients with a non-Covid-19 respiratory infection will be included for the same samples. The proteomic analyses will be performed from classicaly draught blood, blood drop on silica, and saliva, to search for discriminating profiles between Covid-19 and non-Covid-19. Phase 2: 150 patients with a suspected Covid-19 will be included at the same time than the Covid-19PCR is performed ; they will have a sample of saliva and of a drop of blood for proteomic analysis, whose results will be matched with PCR results.
Evaluation of the agreement between fingerstick samples, venous blood, serum and plasma samples when using the LumiraDx SARS-CoV-2 Ab Test against the reference method, using standard qualitative comparison techniques.
Abstract Title: Randomized,open-label, controlled trial to evaluate efficacy and safety of a highly selective semipermeable membrane (AN69-Oxiris) in comparison with a selective semipermeable membrane ( standard AN69) in COVID-19 associated acute kidney injury: oXAKI-COV study Rationale: Acute kidney injury (AKI) in critically ill mechanically ventilated patients with COVID-19 disease, is present in up to 30% of this group and more than 50% of them will need renal replacement therapy in the form of continuous renal replacement therapy (CRRT). Acute kidney injury in this context seems to be a marker of multiorgan dysfunction and it produces increased mortality in this population. There is a vast amount of mechanisms that lead to AKI in critically ill patients with COVID-19; however, the cytokine storm could be the strongest mechanism implicated in AKI development in individuals with continuous renal replacement therapy requirements. Therefore, blocking or reducing the cytokine storm is thought to be a therapeutic target. Highly selective semipermeable membranes (AN69-Oxiris) have been shown able to adsorb endotoxins and to eliminate inflammatory cytokines, thus representing a valuable therapeutic option in this infection. Objective: To demonstrate clinical efficacy of AN69-Oxiris membrane to reach a stable MAP, with less vasopressor dosing (at least 0.1 micrograms/kg/min) after 72h of treatment, compared to a conventional membrane (standard AN69) in critically ill patients with AKI, COVID-19 infection and requirement of continuous renal replacement therapy. Study design: Randomized,open-label, controlled trial in critically ill patients with suspected or confirmed COVID-19 disease, AKI, and criteria for continuous renal replacement therapy initiation admitted in any of the two participating institutions. Patients meeting inclusion criteria will be randomized to receive CRRT with AN69-Oxiris membrane or standard AN69 membrane during a 72h period.
Aim: We aim to evaluate αvβ3 integrin expression in proven COVID-19 infected patients with indicative findings on routine contrast-enhanced CT using [68Ga]Ga-DOTA-(RGD)2. If activated vascular endothelium in the lung parenchyma proceeds ARDS, as frequently observed during COVID-19 infection, imaging αvβ3 integrin expression using PET/CT could have potential as a clinical tool to characterize patients at early stages during disease and guide development of novel treatments targeting the vascular endothelium. Study design: This is a prospective, observational non-randomized pilot study. Maximum 10 patients will undergo a [68Ga]Ga-DOTA-(RGD)2 PET/CT scan and CT-subtraction scan in the same procedure. 10-minutes/bed position static [68Ga]Ga-DOTA-(RGD)2 PET/CT scans of the thorax will be acquired starting at 60 minutes post injection. Study population: Maximum 10 patients from the Infectious Diseases ward with proven COVID-19 infection and indicative pulmonary abnormalities on contrast-enhanced CT (CORADS 4-5) undergo PET/CT scans after injection of 70 μg (200 MBq) [68Ga]Ga-DOTA-(RGD)2 and CT-subtraction. Intervention: All patients will undergo a [68Ga]Ga-DOTA-(RGD)2 PET/CT scan, and in the same procedure, a CT-subtraction scan. Primary study objective: The primary objective of this study is to demonstrate and quantitate activation of the endothelium in the lung vasculature using [68Ga]Ga-DOTA-(RGD)2 PET/CT. Secondary study objectives: 1. To assess the spatial correlation between [68Ga]Ga-DOTA-(RGD)2 uptake and abnormal findings on routine contrast-enhanced CT scan of the chest 2. To assess the spatial correlation between [68Ga]Ga-DOTA-(RGD)2 and CTS of the lung parenchyma 3. To assess the correlation between [68Ga]Ga-DOTA-(RGD)2 and laboratory results 4. To explore the correlation between [68Ga]Ga-DOTA-(RGD)2 uptake and clinical course of disease
Background - A novel coronavirus, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), was first identified in December 2019 as the cause of a respiratory illness COVID-19 in Wuhan City, China. WHO declared a public health emergency outbreak of this virus on 30 January 2020 and declared COVID-19 a global pandemic on 11 March, 2020. Bangladesh reported its first case on March 8, 2020 and first fatality on April 1, 2020. Bangladesh had shown a staggered course of COVID-19 transmission initially but a surge in cases was observed from April, 2020. Remdesivir remains as the only potential therapy for the treatment of COVID-19 till date. Based on several pre-clinical studies in SARS-CoV and MERS-CoV infections, Animal trials in COVID-19 and data from human trials, this randomized, controlled, open label trial will evaluate the antiviral activity and safety of Remdesivir in Bangladeshi hospitalized patients with severe COVID-19. This study finding will provide knowledge if Remdesivir is effective enough to treat Bangladeshi COVID-19 hospitalized patients with adequate safety and tolerability. The result of this study will help the key opinion leaders regarding the matter, to take appropriate decision regarding usage of Remdesivir for the treatment of COVID-19 in Bangladesh. Study Procedure - All patients will receive the standard medical care for COVID-19+ve at the respective hospitals. Vital signs will be recorded every 24 hrs for 1st 5 days then once in 2 days till discharge or as per the discretion of the attending physicians. After screening the COVID-19 confirmed patients will be randomized into 2 treatment arms. Patient's safety assessment e. g. blood parameters (CBC, Creatinine, SGPT, RBS, Creatinine, Creatinine Clearance) will be done on screening, day 5 and day 14 or discharge; Chest X-ray and ECG on screening and day 14 or discharge. SARS-CoV-2 (viral load) will be looked in on day 5, day 10 and day 14 or at the time of discharge. In case any study patient deteriorates during the study period will be managed as per the guideline of that particular hospital and if needed will be shifted to ICU. Patients who will recover will be discharged as per the national guideline for the COVID-19 hospitalized patients. Patients will be contacted at 28 days either over phone or in person to get their health status since discharge.
