PRO-SERO-COV: Serological Response to SARS-Cov-2 Virus in Personnel of the Institut Bergonié in the Context of the COVID-19 Pandemic
Study Details
Study Description
Brief Summary
The question of the immune response of the population, particularly of professional populations in contact with vulnerable populations (such as those with chronic conditions such as cancer), is an important issue. Knowing the evolution of this response over time in this population can help answer outstanding questions. The PRO-SERO-COV study is a seroprevalence study of caregivers working in the hospital sector with a follow-up at 3 months and 12 months. The objective is to evaluate and monitor at 3 and 12 months the serological immune status to an infection by the SARS-CoV-2 virus in active volunteer professionals working at the Institut Bergonié with different types of exposure: healthcare professionals and professionals in other services.

Outcome Measures
Primary Outcome Measures
- Serological immune status to an infection by the SARS-CoV-2 virus [Time 0 (Inclusion)]
This will be determined from the detection of specific antibodies (immunoglobulins: IgM and IgG) or total antibodies carried out using the ELISA/ECLIA method allowing qualitative and semi-quantitative measures. These ELISA/ECLIA tests will be carried out in the medical biology laboratory of the Institut Bergonié.
Secondary Outcome Measures
- Serological immune status to an infection by the SARS-CoV-2 virus [3 months, 12 months]
This will be determined from the detection of specific antibodies (immunoglobulins: IgM and IgG) or total antibodies carried out using the ELISA/ECLIA method allowing qualitative and semi-quantitative measures. These ELISA/ECLIA tests will be carried out in the medical biology laboratory of the Institut Bergonié.
- Serological immune status to an infection by the SARS-CoV-2 virus [Time 0 (inclusion), 3 months, 12 months]
This will be determined from the detection of specific antibodies (immunoglobulins: IgA) carried out using the ELISA/ECLIA method allowing qualitative and semi-quantitative measures. These ELISA/ECLIA tests will be carried out in the medical biology laboratory of the Institut Bergonié.
- The serological immune status to infection with the SARS-CoV-2 virus will also be determined from the different antibody isotypes (IgG and IgM), from a rapid diagnostic unit test (RDT). [Time 0 (inclusion), 3 months, 12 months]
Assessment using a " rapid test on cassette ".
- kinetics of antibody production (IgG) against the SARS-CoV-2 virus [Time 0 (inclusion), 3 months, 12 months]
- kinetics of antibody production (IgM) against the SARS-CoV-2 virus [Time 0 (inclusion), 3 months, 12 months]
- kinetics of antibody production (IgA) against the SARS-CoV-2 virus [Time 0 (inclusion), 3 months, 12 months]
- active COVID-19 infection [Time 0 (inclusion), 3 months, 12 months]
Defined by a positive result for the molecular test for the detection of the SARS-CoV-2 coronavirus genome by RT-PCR.
- symptoms of anxiety [Time 0 (inclusion), 3 months, 12 months]
GAD-7 self-questionnaire (Spitzer et al. 2006), whose score varies from 0 to 21. The recommended threshold for estimating generalized anxiety is 10 points
