A recent study has demonstrated that in low respiratory infections, a strategy using prescription of antibiotics based on the pro-calcitonin level allows decreasing recourse to antibiotics by 47% without prognostic modification.

The aim is to evaluate the impact on antibiotics consumption of an algorithm using procalcitonin level in patients exhibiting severe sepsis symptomatology but without clearly identified hosted germs or infectious centre.

This multicenter study is a randomized prospective open study involving 9 ICU departments in France, comparing two strategies on antibiotherapy treatment period one based on procalcitonin level(experimental group) the other on physician's appreciation(control group)

140 adult patients should be included with a severe sepsis symptomatology, whose infectious etiology has not been proven. The main non-inclusion criterium is: the presence of a pathogen agent or infectious centre clearly identified.

The primary outcome is the rate of patients undergoing antibiotic treatment at D5.

Secondary outcomes: duration of the antibiotic treatment, mortality rate and duration in stay in intensive care ward and evolution of the SOFA score between D0, D3 and D5.

Duration of patient enrollment is 30 days.

Further study details as provided by Brahms France:

Primary Outcome Measures:
  • rate of patients undergoing antibiotic treatment at D5. [ Time Frame: at D5 ]

Secondary Outcome Measures:
  • evolution of the SOFA score between D0, D3 and D5. [ Time Frame: D30 ]

Enrollment: 62
Study Start Date: December 2007
Study Completion Date: March 2010
Primary Completion Date: January 2010 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Procalcitonin level
duration of the antibiotic treatment guided by procalcitonin level
Other: Procalcitonin level

The duration of antibiotic treatment is based on PCT level:

  • < 0.25 ng/ml: antibiotic should be stopped
  • 0.25 < PCT <0.5: antibiotic prescription is not recommended
  • > 0.5 ng/ml: antibiotic should be used
No Intervention: physician's appreciation
duration of the antibiotic treatment based on physician's appreciation
