Coronavirus Infections

This is a prospective observational cohort study that will define the prevalence and incidence of CA-SARS-Cov2 infection using serological and PCR tests in a group of subjects during deconfinement. The team wishes to include approximately 1000 subjects in this study. The health crisis through containment has also created unprecedented environmental conditions with the very clear decrease in economic activities and a consequent decrease in exposure to the main air pollutants. The aim is therefore to carry out a case-control study in which each subject will be his or her own control in unexposed condition (to PM2.5, PM10, NO...) then exposed (after the recovery of economic activity and the usual levels of air pollutants) and to measure the impact of these pollutants on the immune system and epigenetic markers taking into account seasonality. The occurrence of infectious, cardiovascular, allergic and autoimmune events will then be measured according to the immunological profiles measured at inclusion.

The overarching goal of this study is to determine if baricitinib, as compared to placebo, will improve neurocognitive function, along with measures of physical function, quality of life, post-exertional malaise, effect of breathlessness on daily activities, post-COVID-19 symptom burden, and biomarkers of inflammation and viral measures, in participants with Long COVID.

Collection and analysis of demographic, clinical, radiographic and laboratory characteristics of CoViD-19 patients to identify predictors of disease severity, mortality and treatment response, and to identify subgroup of patients that might benefit from specific therapeutic interventions

The COntAGIouS trial (COvid-19 Advanced Genetic and Immunologic Sampling; an in-depth characterization of the dynamic host immune response to coronavirus SARS-CoV-2) proposes a transdisciplinary approach to identify host factors resulting in hyper-susceptibility to SARS-CoV-2 infection, which is urgently needed for directed medical interventions.
