Study of the Vascular Compartment and Hypercoagulability During Coronavirus Infection COVID-19 (COVID'HEMOS)

June 5, 2020 updated by: University Hospital, Rouen

Coronavirus COVID-19 is an emerging virus also called Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2). Eighty percent of patients are poor or asymptomatic. However, there are major respiratory complications for some patients, requiring intensive care hospitalization and possibly leading to death in 5% of cases. One of the hypotheses put forward is that much of the pathophysiology is due to endothelial dysfunction associated with disseminated intravascular coagulation.

The covid-19 pathology could induce coagulation impairment as observed during sepsis. An increase in D-dimer levels during covid-19 disease is itself associated with excess mortality. While D-dimers are highly sensitive, they are not specific for clotting activity. They may be increased in many other circumstances, particularly in inflammation.

On the other hand, the infection stimulates the release of extracellular vesicles. These vesicles, of multiple cellular origin, are an actor of vascular homeostasis, and participate in the state of hyperactivation of coagulation. They have a major role in the prothrombotic state and the development of coagulopathy associated with sepsis.

The aim of our monocentric prospective study would be to study early and more specific markers of hypercoagulability and markers of routine endothelial dysfunction, as soon as the patient is hospitalized, in order to predict the risk of hospitalization in intensive care.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.
99

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.
