Open Access Abstract Introduction Combination antibiotic therapy for ventilator associated pneumonia VAP is often used to broaden the spectrum of activity of empirical treatment. The relevance of such synergy is commonly supposed but poorly supported. The aim of the present study was to compare the clinical outcome and the course of biological variables in patients treated for a VAP using a monotherapy with a beta-lactam versus a combination therapy. Methods Patients with VAP were prospectively randomised to receive either cefepime alone or cefepime in association with amikacin or levofloxacin. Clinical and inflammatory parameters were measured on the day of inclusion and thereafter. Results Seventy-four mechanically ventilated patients meeting clinical criteria for VAP were enrolled in the study. VAP was mierobiologieally confirmed in 59 patients 84 . Patients were randomised to receive cefepime C group 20 patients cefepime with .
