BACKGROUND: Methicillin-resistant Staphylococcus aureus (MRSA) is a common cause of ventilator-associated pneumonia (VAP). This prospective, open-label, multicenter clinical trial compared the early microbiological efficacy of linezolid (LZD) therapy with that of vancomycin (VAN) therapy in patients with MRSA VAP. METHODS: A total of 149 patients with suspected MRSA VAP were randomized to receive either LZD, 600 mg, or VAN, 1 g every 12 h. Patients with baseline bronchoscopic BAL (BBAL) fluid quantitative culture findings that were positive for MRSA (>or= 10(4) cfu/mL) comprised the study population. The primary outcome was microbiological response (Early microbiological cure rates were not statistically significantly higher with LZD therapy than with VAN therapy despite trends in all secondary clinical outcomes favoring LZD therapy. These results suggest that any beneficial effect of LZD therapy may be due to factors other than increased bacterial clearance. Trial registration: Identifier: NCT00572559.
