Background: To assess efficacy and tolerability of pefloxacin in association with other antibiotics in the treatment of acute and chronic bone and joint infections.
Methods: From January to December 1997, all the outpatients with diagnosis of acute or chronic bone and joint infections have been enrolled in a perspective study. If possible a cultural or histopathological study was performed. Treatment response was evaluated with radiological and clinical chemistry parameters.
Results: Fifteen patients [10 males, 5 females; mean age 40.7 +/- 15 years (range 15-71)] have been studied. They had 5 knee septic arthritis, 1 sacroileitis, 1 hip septic arthritis, 4 long bone osteomyelitis, 1 sterum osteomyelitis, 3 spondilitis. Three patients were HIV infected. Twelve were acute infections, 3 chronic ones. Overall, 7 were hematogenous infections, 6 subsequent to elective surgery, 1 post-traumatic thighbone osteomyelitis, 1 osteomyelitis by external fixation device. Isolates were S. aureus in 5 cases, P. mirabilis in 1 case, S. aureus+ Serratia marcescens in 1. In the remaining part cultural tests were negative. Pefloxacin was administered i.v. or orally at the dose of 400 mg/bid for a mean time of 114 +/- 74.5 days (range 30-270) in association with other chemotherapic agents. Ten good recoveries, 3 partial and 2 no responses were observed.
Conclusions: Pefloxacin resulted to be useful in the treatment of acute and chronic bone and joint infections. No severe side effect was observed during the treatment.
