Study population: Patients ≥18 years old admitted to the Barts NHS Trust who have a diagnosis of COVID-19.

About this study
COVID-19 is associated with complications including ARDS and myocardial injury, which informs prognosis and patient outcome. The laboratory plans to perform immunophenotyping of peripheral T-cells in patients with COVID-19 and complications (ARDS, ITU admission, myocardial injury) and map this against clinical patient outcomes. The aim is to determine if there is a specific T-cell immunophenotype associated with COVID-19 and/or complications, which can be used to inform prognosis and potential therapies.
Read the detailed description
Infection with the novel coronavirus COVID-19 is designated a pandemic by the World Health Organisation (WHO).COVID-19 infection can result in severe lung inflammation which, when present, dominates the clinical course for most patients. However, other organs may also be involved and the cardiovascular (CV) system appears to have complex interactions with COVID-19. Published reports suggest evidence of heart muscle damage in 20-40% of hospitalised cases presenting as cardiac chest pain, heart failure, abnormal heart rhythms and cardiac death.
Many affected were previously well, but approximately half of those admitted to hospital COVID-19 have other medical problems, increasing in those requiring ITU admission or those that died. Patients with pre-existing CV conditions have some of the worst outcomes. Although pre-existing disorders reduce an individual's capacity to withstand severe illness, it is also likely that CV diseases may increase the risk of developing complicated COVID-19 disease. Our hypothesis is that immunological abnormalities acquired as a consequence of pre-existing disorders is responsible for this.
A question central to potential therapeutic options is the extent to which COVID-19 related myocardial injury results from viral replication (cytopathic), is immune mediated or is due to other mechanisms. Given that rapid onset cardiac injury can occur at 7-14 days after onset of COVID symptoms we propose to evaluate the contribution of adaptive T-cell mediated immunity in patients with and without myocardial injury. If successful, we may be able to identify treatments that suppress discrete components of the immune system to prevent myocardial damage without depressing protective immune function.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
COVID-19 is associated with complications including ARDS and myocardial injury, which informs prognosis and patient outcome. The laboratory plans to perform immunophenotyping of peripheral T-cells in patients with COVID-19 and complications (ARDS, ITU admission, myocardial injury) and map this against clinical patient outcomes. The aim is to determine if there is a specific T-cell immunophenotype associated with COVID-19 and/or complications, which can be used to inform prognosis and potential therapies.

Infection with the novel coronavirus COVID-19 is designated a pandemic by the World Health Organisation (WHO).COVID-19 infection can result in severe lung inflammation which, when present, dominates the clinical course for most patients. However, other organs may also be involved and the cardiovascular (CV) system appears to have complex interactions with COVID-19. Published reports suggest evidence of heart muscle damage in 20-40% of hospitalised cases presenting as cardiac chest pain, heart failure, abnormal heart rhythms and cardiac death.
Many affected were previously well, but approximately half of those admitted to hospital COVID-19 have other medical problems, increasing in those requiring ITU admission or those that died. Patients with pre-existing CV conditions have some of the worst outcomes. Although pre-existing disorders reduce an individual's capacity to withstand severe illness, it is also likely that CV diseases may increase the risk of developing complicated COVID-19 disease. Our hypothesis is that immunological abnormalities acquired as a consequence of pre-existing disorders is responsible for this.

Questions about this trial
What is this clinical trial studying?
An observational study of Cardiovascular Disease Acute and Cardiomyopathies, run by Barts & The London NHS Trust at 1 site in United Kingdom.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: withdrawn, as of the sponsor's last update on 21 Apr 2023. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United Kingdom. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study was withdrawn before enrolling participants, so there are no results.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
T-cell immunophenotype (time frame: 12 months from enrollment). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT04340921, which also lists 12 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 21 Apr 2023.
