Clinical Trial Summary

The objective of this pilot study is to estimate a procedure where the biological samples routinely obtained at the site of suspected infection could be guided by the early realization of a TEP with FDG coupled to scanner X, in patients hospitalized in ICU for severe sepsis of unspecified etiology.


Clinical Trial Description

Severe sepsis constitutes the leading cause of mortality in ICU, in particular because a microbial documentation is lacking in about half of the cases.

Tomography by emission of positons, which uses the property of activated macrophages and leucocytes to collect 18F-fluorodeoxyglucose may prove useful to identify the site(s) of infection and then guide sampling.

Thirty patients will be included over 12 months.

Within 24 hours after admission, patients presented with a severe sepsis of still unknown etiology will benefit from the realization of a morphoTEP, including an examination MtOe with the FDG, associated with a conventional scanner X.

Suspected infected sites will then be the subject of sampling when possible. These samples will be send for microbial culture, histology and TREM-1 expression (membrane-bound and soluble form) when appropriate.

The main judgement criteria will be the percentage of the MtOe exams proved to be useful for diagnosis and/or associated with therapeutic modifications.

This pilot study will make it possible to evaluate the interest of the early realization of a TEP/scanner X examination among severe sepsis patients of unknown origin. ;
