Linezolid is an attractive alternative for the treatment of chronic bone and joint infections because it is active against common pathogens including methicillin-resistant staphylococci and vancomycin-resistant enterococci and because its oral formulation is convenient for long-term administration. To evaluate the ability of linezolid to produce long-term remission, we prospectively monitored 11 consecutive adult patients who received linezolid for osteomyelitis (n = 9) or prosthetic joint infection (n = 2). Linezolid 600 mg was administered orally twice daily for a mean of 10 weeks (range, 6 to 19 weeks). Pathogens were methicillin-resistant Staphylococcus aureus (n = 5), methicillin-resistant coagulase-negative staphylococci (n = 4), vancomycin-resistant Enterococcus faecium (n = 1), and vancomycin-sensitive Enterococcus faecalis (n = 1). After a mean followup of 27 months (range, 17 to 41 months), all 11 patients had remission by clinical, laboratory, and radiographic criteria. During week 8 of linezolid treatment, one patient developed a gram-negative superinfection, which resolved with appropriate therapy. During week 6 of linezolid treatment, one patient developed mild thrombocytopenia and another patient developed mild anemia. Both episodes of myelosuppression were reversible within 10 days after completing the planned 6-week courses of linezolid. We recommend weekly complete blood counts to detect hematologic abnormalities. We conclude that oral linezolid seems to be a useful and convenient alternative for the treatment of bone and joint infections.
