Clinical Trial Summary

The objective of the present study is to describe the negative impact on oral and gut microbiota of a severe acute respiratory syndrome SARS-CoV-2 infection in patients hospitalized in intensive care units (ICU). The study would like to compare their microbiota to the microbiota of ICU patients, non-infected by the SARS-CoV-2.


Clinical Trial Description

Gut microbiota in ICU patients is sorely distorted, there is an important loss of diversity which can be traduced by a decrease of commensal bacteria and an increase of pathogens. The virulence, infectivity, and transmissibility of the emerging SARS-Coronavirus 2 is a reason for us to find strategies and therapeutics to curb the epidemic. Gut mucosa is very probably a target for the virus and it seems likely that feces are a way of transmissibility. It suppose too that gut microbiota is more weathered in patients with a SARS-CoV-2 infection, moreover if they have to be hospitalized in ICU. For this reason, the present study would like to collect oral and rectal swab from patients hospitalized in ICU for a serious SARS-CoV-2 infection and from patients hospitalized in ICU for another reason that a SARS-CoV-2 infection at day 1, each 7 days and at the end of their ICU stay. Other objectives are to know if this distorted microbiota is a risk factor for poor outcomes in our ICU patients, if antibiotics and artificial nutrition are too a risk factor of weathered microbiota and finally if we can connect oral and rectal dysbiosis to use the oral dysbiosis to predict the rectal dysbiosis in view of the ease to collect oral sample. ;
