Filter by:The purpose of the study is to assess the frequency of the occurrence of a venous thrombosis in patients with the new Coronavirus disease, who are admitted to the Intensive Care Unit for impending respiratory failure requiring intubation and mechanical ventilation. Furthermore, the investigators aim at identifying potential risk factors for thrombosis and death.
Background: Each Belgian winter season is characterized by a wave of influenza like and respiratory symptoms. Especially, the elderly people are more vulnerable to be infected by influenza, but also RSV. The recent COVID-19 pandemic and eventually a next wave, will increase the prevalence of influenza like and respiratory symptoms. Method: A multicentre non-commercial cohort study will be conducted in nursing home staff and residents during the Winter season 2020-2021. Objectives: Primary objective is the difference in incidence of influenza like and respiratory symptoms between cases (cases have evidence of past infection with SARS-CoV-2, referred to as Covid +) and controls (controls have no evidence of previous infection and are referred to as Covid -). The primary outcome analysis as well as the secondary outcome analyses will use two strata: nursing home staff and nursing home residents. The secondary objectives are the difference in incidence of COVID-19, influenza, RSV infections confirmed by PCR between cases and controls, to define a correlate of protection in the covid + group against re-infection with SARS-CoV-2 based on the study of the pre-existing antibody profile (antigen specificity, antibody type and antibody level) at the time of re-exposure. A multiplex assay will be used to assess the antibody profile. Finally, to study the COVID-19 disease severity (7 point WHO ordinal scale, this includes a.o. hospitalisation, mechanical ventilation need and ICU admission, mortality) based on the presence/absence of pre-existing antibodies and the pre-existing antibody profile. For other respiratory infections we will study the need for hospitalization and mortality.
Early inhibition of entry and replication of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a very promising therapeutic approach. Polyclonal neutralizing antibodies offers many advantages such as providing immediate immunity, consequently blunt an early pro-inflammatory pathogenic endogenous antibody response and lack of drug-drug interactions1-3. Because a suboptimal endogenous early antibody response with regard to SARS-CoV-2 replication in severe cases is observed, neutralising antibody treatment can be very interesting for patient with COVID-19 induced moderate pneumonia4,5. Convalescent plasma to treat infected patients is therefore an interesting therapeutic option currently under evaluation. However, the difficulties of collecting plasma and its safety aspects are not adapted to many patients. A new polyclonal humanized anti-SARS-CoV2 antibodies (XAV-19) is being developed by Xenothera, which can be administered as intravenous treatment. XAV-19 is a heterologous swine glyco-humanized polyclonal antibody (GH-pAb) raised against the spike protein of SARS-CoV-2, inhibiting infection of ACE-2 positive human cells with SARS-CoV-2. Pharmacokinetic and pharmacodynamic studies have been performed in preclinical models including primates and a First In Human study with another fully representative GH-pAb from Xenothera is ongoing in volunteer patients recipients of a kidney graft. These studies indicated that 5 consecutive administrations of GH-pAbs can be safely performed in humans. The objective of this 2-steps phase 2 randomized double-blind, placebo-controlled study is 1) to define the optimal and safety XAV-19 dose to administrate in patients with COVID-19 induced moderate pneumonia ; 2) to show the clinical benefit of selected dose of XAV-19 when administered to patients with COVID-19 induced moderate pneumonia.
A multicenter randomized, double-blind, placebo-controlled clinical trial of Convalescent SARS COVID-19 plasma versus Placebo to evaluate the effect between arms on an ordinal score of six mutually exclusive categories of clinical status at day 30 after study initiation.
Oslo University Hospital has initiated an observational study on hospitalised patients with confirmed COVID-19, the infection caused by Severe Acute Respiratory Syndrome Coronavirus type 2 (SARS-CoV-2).
A team at the University of Manchester are developing a test that tcould be helpful in detecting immunity to the Coronavirus (which causes the COVID-19 disease) in participants with inflammatory arthritis. It is based on a flu assay has already developed; the team will replace the flu antigen with a Coronavirus antigen to see if it is effective. This project aims to develop a test to see if people who have had the virus have developed immunity to it. This could help to predict who might or might not get the disease a second time, who should stay at home to be protected from potential infection or who will not develop any symptoms, even if exposed to the virus. When vaccination trials against the Coronavirus will be launched, this test could also help to see if the vaccine is effective.
High-throughput screening studies identified Abl kinase inhibitors (including imatinib) as inhibitors of coronaviruses SARS and MERS. The SARS-CoV-2 coronavirus depend on Abl2 kinase activity to fuse and enter into the cells. Pharmacokinetic studies demonstrated that IC50 of imatinib for ABL1, BCR-ABL1 and ABL2 kinase inhibition is less than 1 microM (around 0.3 microM) below the expected trough plasmatic concentrations of imatinib 400 mg/day (1.7 microM). The EC50 of imatinib for the inhibition of the virus is under investigation but we now have a first estimates with EC50 close to 2.5 microM. This plasmatic concentration is achievable with imatinib 800 mg/d. We hypothesize that clinically achievable imatinib concentration will block the first round of cell to cell virus infection and therefore stop or prevent from SARS-CoV-2 infection in human. Based on our 20 years' experience of prescribing imatinib in patients, we expect that most of the adverse events and pharmacological interactions of imatinib can be anticipated and corrected. The eligible population will be aged (>70y) patients hospitalized for a non-severe COVID-19 disease for less than 7 days. Patients will be randomized 1/1 between standard of care and imatinib 800 mg per day during 14 days. The primary endpoint will be the death rate by 30 days. Secondary endpoint will include progression to severe CIVID-19 disease, safety, outcome at 3 months. We plan to randomize 90 patients in order to show a 10% benefit in term of death rate reduction from 16% to 6%.
SARS-CoV has caused severe epidemic respiratory disease in human populations. By July 2003, a total of 8,096 probable cases of SARS had been reported including 774 deaths in 27 countries, around one-third of which were health care workers (HCWs). Previous studies have been reported about long-term impacts of SARS infection, including lung function deficiency, steroid-induced osteonecrosis, reduced exercise capacity, and impairment in health-related quality of life (HRQoL). HCWs, especially nurses, have been reported to experience greater psychological distress, particularly increased levels of posttraumatic stress symptomatology (PTSS). But the very complex impacts of this fatal infection on HCWs have not been fully elucidated. It is thus important to follow these occupational patients to detect and manage multi-organ sequelae and functional impairment.
Severe Acute Respiratory Syndrome (SARS) is a newly recognized illness that can be fatal. The purpose of this study is to better understand SARS by collecting samples of blood and other body fluids of people who have been exposed to SARS or who are suspected to have the illness. Up to 300 volunteers aged 18 years or older will be enrolled in this study. Participants will donate blood samples and, if appropriate, samples of fluid from the lungs, nose, or throat. Researchers will test these samples for proteins that control or mediate inflammatory or immune responses. The patterns of these proteins will reveal how SARS affects the body and the efforts the body makes to fight off the infection.
