Impact of 18 FDG PET/CT on the Management of Patients With Staphylococcus Aureus Bloodstream Infection

France291 participantsStarted 2018-01-29

Plain-language summary

S. aureus bloodstream infection (SAB) is a severe disease associated with a 30% case-fatality rate at 12 weeks. Severity of this disease is related to the high prevalence of staphylococcal Deep Foci of Infection (SA-DFI), which require prolonged duration of antimicrobial therapy and specific treatment. Timely diagnosis and management of SA-DFI is associated with an improvement of prognosis during SAB. 18 FDG PET/CT (PET/CT) is a useful tool in the diagnosis of infectious foci during bacterial infections. An ecological study performed in the Netherlands has shown that use of PET/CT in patients with Gram positive cocci bloodstream infection was associated with an increase of detection of DFI and a decrease of recurrences and mortality compared to historical controls. The investigators hypothesize that SAB poor prognosis is in part related to the lack of diagnosis of all infectious foci and consequently to a suboptimal treatment.
