About this study

The main objective is to quantify the population of reverse migrating neutrophils in patients with COVID-19.

Read the detailed description

This is a non-interventional transversal research whose main objective is to quantify the population of reverse migrating neutrophils in patients with COVID-19.

Design:

A multicentric (3 sites) clinical trial

Sample size :

200 patients

Population concerned:

Patients hospitalized in intensive care with SARS-CoV-2 infection confirmed by RT-PCR from a nasopharyngeal swab.

Duration of participation (treatment + follow-up): until the patient is discharged from the ICU and within 2 months top.

No interim analysis is planned. Analysis will be performed at the end of the study.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Percentage of circulating neutrophils in reverse migration

    Percentage of circulating neutrophils in reverse migration determined on a sample taken during the admission of COVID 19 patients to Intensive Care Units by flow cytometry: the samples will be incubated for 45 minutes with anti-human CXCR1, CD11c, CD11b, and CD62L antibodies. Erythrocytes will be lysed and fixed leukocytes will be analyzed by flow cytometry.

    Measured: Within 4 hours following the patient admission in Intensive Care Units (ICU).

Secondary outcomes (4)
  1. Analysis of neutrophils and platelets

    The analysis of neutrophils and platelets, and of the inflammatory environment will be carried out on a sample taken on admission of patients to Intensive Care Units

    1. Phenotypic and functional analysis of neutrophils
    • Measurement of the oxidative explosion
    • Measurement of neutrophil apoptosis
    • Measurement of intravascular NETosis
    1. Analysis of platelet aggregation and activation
    • Quantification of the fraction of immature platelets (IPF)
    • Contribution of platelets to clot stiffness
    • ELISA assay of soluble platelet activation markers
    • Measurement of D-Dimers, von Willebrand factor, thrombin-antithrombin complex (TAT), α2-Plasmin-Plasmin-inhibitor

    Measured: Within 4 hours following the patient admission in Intensive Care Units (ICU).

  2. SAPS II score

    Assessment of the link between phenotypic and functional markers of neutrophils on admission to the ICU.

    The severity of the disease is determined using clinical scores (SAPS II ("simplified acute physiology") and SOFA ("Sequential Organ Failure Assessment") (global SOFA, respiratory and non-respiratory) scores; these scores will be assessed during the period of hospitalization in Intensive Care Units. An association between these 2 scores (SAPSII and SOFA scores) and the neutrophil markers will be sought.

    Measured: From admission to the follow-up visits (Day 3, Day 7 and as part of usual care every 7 days until the patient is discharged and within 2 months top).

  3. SOFA score

    Assessment of the link between phenotypic and functional markers of neutrophils on admission to the ICU.

    The severity of the disease is determined using clinical scores (SAPS II ("simplified acute physiology") and SOFA ("Sequential Organ Failure Assessment") (global SOFA, respiratory and non-respiratory) scores; these scores will be assessed during the period of hospitalization in Intensive Care Units. An association between these 2 scores (SAPSII and SOFA scores) and the neutrophil markers will be sought.

    Measured: From admission to the follow-up visits (Day 3, Day 7 and as part of usual care every 7 days until the patient is discharged and within 2 months top).

  4. Mortality rate

    The mortality occurring within 2 months of admission of patients to an ICU will also be assessed.

    Measured: 2 months

Questions about this trial

What is this clinical trial studying?

An observational study of Covid19, run by Assistance Publique - Hôpitaux de Paris at 1 site in France.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 2 exclusion criteria. 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: status not confirmed, as of the sponsor's last update on 18 Jun 2021. 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 France. 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?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Hafid AIT-OUFELLA, Professor (01 49 28 23 15, hafid.aitoufella@aphp.fr), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Percentage of circulating neutrophils in reverse migration (time frame: Within 4 hours following the patient admission in Intensive Care Units (ICU).). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 18 Jun 2021.
