Background: Pyogenic vertebral osteomyelitis (PVO) is a severe infection that requires prolonged antimicrobial therapy and/or surgical interventions. Limited data are available on the safety and clinical efficacy of tigecycline in PVO. The objective of this study was to describe the clinical outcomes of patients treated with tigecycline for culture-negative PVO that was unresponsive to empirical antibiotic therapy including intravenous ampicillin-sulbactam plus ciprofloxacin or ampicillin-sulbactam alone. Methods: We retrospectively reviewed 15 patients with culture-negative PVO from 2009 through 2014. The patients received tigecycline as secondary empirical therapy, after not responding to the first empirical therapy. Clinical success was defined as recovery from symptoms and normalization of laboratory parameters at the end of therapy. Continued clinical success at 24 weeks after the end of the therapy was defined as sustained clinical success. Results: Tigecycline treatment was completed in 14 patients and discontinued in 1 due to severe nausea and vomiting. The mean age of the patients was 67.7 years (range 58-77 years), and 57.1% (8/14) were women. In all, 78.6% (11/14) of patients had risk factors for probable resistant staphylococcal and gram-negative infections such as diabetes mellitus, presence of hemodialysis catheters, and prior antibiotic usage. The average duration of tigecycline treatment was 8.3 weeks (range 6-11 weeks). Sustained clinical success was obtained in all patients. Conclusions: Tigecycline should be considered as an alternative agent for the treatment of PVO in selected patients due to microbiological activity against resistant gram-positive and gram-negative bacteria.
