Abstract
Cefotaxime, a new cephalosporin, was evaluated for efficacy and safety in the treatment of 52 patients with serious bone and joint infections. For five of these patients therapy could not be evaluated. Diagnosis of osteomyelitis or septic arthritis was made on the basis of clinical and roentgenographic evidence of infection. The diagnosis of a bone infection was confirmed by either a positive culture of a bone biopsy or of blood in combination with a positive bone scan or roentgenogram. The diagnosis of a joint infection was confirmed by a positive culture of joint aspirate samples. Osteomyelitis was arrested in 93% (15 of 16 patients) of cases of acute osteomyelitis, 89% (24 of 27 patients) of cases of chronic osteomyelitis, and 100% (4 of 4 patients) of cases of septic arthritis. Follow-up ranged from 0–17 months after completion of cefotaxime therapy. Laboratory monitoring revealed positive direct Coombs' test (six patients), neutropenia <1,000 polymorphonuclear leukocytes (two patients), macular rash (two patients), phlebitis (two patients), and pseudomembranous colitis (one patient). It is concluded that cefotaxime is a useful and safe antibiotic for the treatment of osteomyelitis and septic arthritis.
