HYGIEIA is a monocentric prospective interventional study. The study has two parts, Part 1 with prospective data and sampling, and Part 2 based on samples that were previously collected and stored within COBISA study (2020/11MAI/269).~i. In Part 1, patients acutely infected with SARS-COV-2 will be proposed inclusion. Included patients will be sampled at two different time points (acute infection and convalescent phase, i.e. 8-12 weeks later). Samples will be analysed using cutting edge -omics technologies in order to characterize the genotypic, proteomic, transcriptomic, metabolomic and respiratory microbiota/virome profile through explorative approaches. Clinical and routine biological data will be prospectively collected either as outpatients or during the acute hospitalization and convalescent phase.~ii. In Part 2, samples collected and biobanked during the COBISA study (2020/11MAI/269) will be analysed similarly to the samples collected during the prospective part. Clinical and routine biological data will be retrospectively collected using the patients electronic medical record (EMR).~Generated data will be integrated using a systems biology approach with algorithms developed by a biostatistics team.
In this study, the investigators aim to collect phenotypical and extensive unbiased multimodal biological data, at two different time points, and to integrate them using a systems biology approach.~The present project aims at generating a systems biology network that can recapitulate the complexity of processes underlying differential SARS-CoV-2 phenotypic responses through exploitation of clinical -omics data. Identifying key determinants and mechanisms of biological variability responsible for phenotypic differences will lead to a better management of patients through the application of precision medicine.
