Filter by:DESIGN Longitudinal prospective observational multicentre study. Primary objective: Understand the immune mechanisms driving COVID-19 disease in patients with a history of lung disease
The aim of this possible study is to identify if SARS-CoV-2 can be found in the tear film and conjunctiva of a patient with COVID-19.
To evaluate the incidence of patients with a positive test for SARS-CoV-2, performed in the preoperative screening for patients treated at the institution
Observational and prospective study with one year of follow-up of the cohort of workers of the CSdM, including workers of subcontracted companies working in the Hospital of Mataró (2,300 workers approximately) and with controls at baseline and at 3, 6, 9 and 12 months. All CSdM workers will be invited to participate by e-mail and by announcements in the corporate website. A space will be set up on the corporate intranet where workers will be informed about the study, will be able to give their informed consent and will be able to answer an electronic questionnaire regarding socio-demographic, clinical and labour personal characteristics. Once the questionnaire answered, participants will be authorized to schedule a blood extraction. Prevalence of antibodies against SARS-CoV-2 will be analyzed (IgA, IgM, IgG). PCR will be also performed for IgM and IgA positive subjects.
The SARS-CoV-2 infection in the airway epithelium induces cytopathic effects and the cessation of ciliary movement. Increased cytokines and chemokines have been reported to be associated with the severity of the disease. However, most of the molecular and cellular aspects of the inflammatory response and the processes of development of humoral and cellular immunity in these patients are unknown. The aim of this study is characterizing inflammatory processes, seeking to expand the knowledge of the cellular and molecular pathophysiology of COVID-19 that could help in the decision-making of treating health personnel. Mainly, the study is focused on analyzing the inflammatory response by determining cytokines and chemokines. Also, the viral load of the patients with COVID-19 will be determined and will be correlated with the antibody titers. On the other hand, cells will be immunophenotyped to search the cellular depletion profile. Finally, an epidemiological analysis of the patients will be carried out.
QuadraMune(TM) is a nutritional supplement which has previously been demonstrated to possess antiinflammatory and immune modulatory activity based on in vitro and pilot in vivo studies. The current clinical trial aims to assess in a 500 volunteer trial the efficacy of QuadraMune(TM) in reducing infection in individuals at high risk of COVID-19.
In December 2019, a novel coronavirus (SARS-CoV-2) emerged in Wuhan, Hubei, China, and now spreads across international borders. As of 11 April 2020, the total global number of confirmed SARS-CoV-2 cases reached 1,521,252 (92,798 deaths); with 65,081 (7,978 deaths) being reported in the United Kingdom. COVID-19 is the name of the disease associated with SARS-CoV-2 infection and includes a spectrum of illness that ranges from mild infection to severe pneumonia that can progress to respiratory failure and Acute Respiratory Distress Syndrome (ARDS) or septic shock. Between 8 to 15% (depending on geographical setting) of all SARS-CoV-2 positive cases can be classified as severe or necessitating intensive care unit (ICU) admission. In the early stages of the outbreak unfolding, several retrospective case studies and cases series carried out in China reported that those who died were more likely to be male, and more likely to have underlying comorbidities. Prevalence studies conducted in the US and Italy show similar trends in the distribution of comorbidities among SARS-CoV-2 severe cases; adding obesity (BMI>30) to the list of factors potentially associated with disease severity. However, the relative importance of different underlying health conditions remains unclear owing to inadequate adjustment for important confounding factors such as age, sex, and smoking status. We propose a cohort study to evaluate predictors, clinical evolution and excess of mortality of SARS-CoV-2 in hospitalised patients, with two main workstreams- the first looking at all patients admitted to SGHFT and the second looking at patients admitted to ITU with respiratory failure.
Covid-19 infection is due to SARS-CoV-2 member of the Coronavirus family represented by SARS- and MERS-CoVwith neuronal tropism capacity for the brainstem and thalami. Dexmedetomidine has(i) central antihypertensive (ii) sedative and (iii) neuroprotective properties and is often used during patient recovering after mechanical ventilation withdrawal. Dexmedetomidine administration could change the immunomodulatory profile of Covid-19 patients and reduce inflammatory response.CAM-ICU scores and Blood samples from Covid-19 ICU patients will be collected at 4 different timepoints (before Dexmedetomidine administration, at D2, D7 and M6) to analyse the inflammatory profile with different approaches:i) chromatin accessibility, ii) transcriptome analysis, iii) inflammatory cytokines and chemokines levels.
Antioxidants, and particularly polyphenols, have shown protection in respiratory pathologies, which is related to the decrease in the severity of the clinical picture and suppression of inflammation. This suppression of inflammation may be related to the inhibition of NF-kB polyphenols, where its activation is related to the stimulation of 150 stimuli including cytokines (IL-1β, IL-6, THF-α, GM-CSF, MCP-1), TLRs, among others. There may be other additional mechanisms that can help control virus-induced respiratory pathologies, among which are the regulation of reactive oxygen species (ROS) associated with tissue destruction caused by the virus and a selective antiviral action can be reported. direct. The standardized P2Et extract obtained from C. spinosa, by the Immunobiology Group of the Pontificia Universidad Javeriana, is highly antioxidant, decreases lipid peroxidation and tissue damage and induces complete autophagy in stressed or tumor cells. The induction of a full autophagic flow could inhibit the replication of beta-coronaviruses like SARS-CoV-2. Furthermore, P2Et can decrease the factors involved in tissue damage by reducing IL-6 and decrease ILC2 cells of the lung in animals with lung metastases (unpublished data). These antecedents suggest that the supplementation of patients with COVID-19 with the extract P2Et, could improve their general condition and decrease the inflammatory mediators and the viral load.
This study examines the seroprevalence against SARS-CoV-2 in health care workers and patients at the Vienna General Hospital.
