Determination of Germ-Line Variations and Pathological Gene Expression that May Contribute to Immunopathology in COVID-19." The SARS-CoV-2 infection (1, 2), can be followed by a severe evolution with severe respiratory distress. We hypothesize that germline variants in genes involved in innate immunity, especially type I interferon induction and actions, predispose to delayed pathological response/cytokine storm. Our aims are to identify: i) such germ-line variants and ii) peripheral leukocyte gene expression that can predict unfavorable SARS-CoV2 infections. A group of SARS-CoV2 patients with unfavorable evolution, young and without co-morbidities (25) will be compared with an aged matched group of 25 SARS-CoV2 individuals with absence or a minimum of symptoms. Germ line DNA obtained from peripheral blood (PB) will be whole exome sequenced (WES) and analyzed with bioinformatics tools that are used for rare disease germline...

" Predictive plasma signature of the clinical behavior of COVID-19 patients. The clinical presentation of COVID-19 infection varies from mild to asymptomatic to pneumonia, which can be complicated by severe respiratory failure and/or cardiovascular, renal, hepatic and cutaneous involvement. The understanding of such a polymorphism is very incomplete and the prognosis is difficult. Several tracks involving inflammatory reactions are currently favored to better explain this disease. In particular, the significant increase in plasma cytokines IL2, IL7, IL10, GSCF, IP10, MCP1, MIP1A and TNFα, known as "cytokine storm", seems to be significantly associated with the ARDS and multi-organ onsets. In this context, IL6 seems to play an important role and targeted treatments against this cytokine seem promising. Also, the infection of endothelial cells by the coronavirus causing endothelium inflammation have been suggested as one of the fundamental...
