HDL Target of CoViD19 ? Analysis on the Caregivers of the Reunion University Hospital (H-Cov-Run)

August 29, 2022 updated by: Centre Hospitalier Universitaire de la Réunion
Since December 2019, the Severe Acute Respiratory Syndrome-Coronavirus-2 (SARS-CoV-2) pandemic has spread around the world. The people most exposed to this virus remain the healthcare personnel who are on the front line in the fight against this pandemic. Due to the delayed nature of the pandemic in Reunion island and its insular geographical situation, the study of the voluntary medical personnel will allow the investigators to establish a longitudinal follow-up of the anomalies of the lipidic balance in relation to the exposure to the SARS-Cov virus. 2. During bacterial infections, the lipid profiles are profoundly modified with very significant reductions in plasma cholesterol levels, LDL-C but especially HDL-C whose concentrations are particularly low. Lipid profiles are altered during viral infections, for example, the severity of dengue is inversely correlated with total cholesterol and LDL-C but not with HDL-C levels, according to a recent meta-analysis. The hepatitis C virus circulates in serum linked to lipoproteins rich in triglycerides and HDL can facilitate its entry into cells via Scavenger receptor class B type 1 (SRB1). Likewise, it has been shown that apoA1 can bind to the dengue virus and increase its infectivity by promoting its entry into cells, also via SRB1. At the moment, nothing is known about the lipid profiles in subjects with SARS-CoV-2. The investigator hypothesize that a drop in plasma HDL-C levels and a change in their size during infection could justify future therapeutic approaches aimed at supplementing the subjects most at risk of pulmonary complications. In a model of Pseudomonas aeruginosa pneumonia in mice, investigators have shown that the injection of reconstituted HDL allowed to limit the pulmonary inflammation and the deleterious consequences of the infection. The investigator propose to study not only the lipid profiles in subjects who are infected with SARS-CoV-2 but also the polymorphisms of genes involved in the regulation of lipoprotein levels like that of Cholesterol Ester-Transfer Protein (CETP) depending on the developed forms, symptomatic or not.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Active, not recruiting

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.

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.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Change of lipid profile during exposure to SARS-Cov-2
Time Frame: at the end of the study, maximum 1 year
lipid profile
at the end of the study, maximum 1 year

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
HDL-cholesterol size

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
June 17, 2020

Primary Completion (Anticipated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
