摘要
BACKGROUND: One of the most important decisions in the treatment of osteoarticular infections is the time at which parenteral therapy can be changed to oral therapy. C-reactive protein (CRP) is an acute inflammatory indicator with a half-life of 19 hours and thus can be helpful in assessing the adequacy of therapy for bacterial infections. At our institution, a combination of CRP and clinical findings is used to determine the transition to oral therapy.
METHODS: A search of 8 years of electronic records identified children with osteoarticular infections. Only children with culture-positive acute bacterial arthritis (ABA) or acute bacterial osteomyelitis (ABO) were studied further. A primary chart review of demographic and clinical data was conducted, and a secondary chart review of complicated outcomes was performed.
RESULTS: Of 194 total patients, complicated outcomes occurred in 40, of which 35 were prolonged therapy. Only 1 microbiologic failure occurred, presumably due to a retained intra-articular fragment of infected bone. CRP was highest initially among patients with simultaneous ABO + ABA and among those with complicated outcomes, and was lower at the transition to oral therapy in the complicated outcome group (1.5 vs 2.1 mg/dL; P = .012).
CONCLUSIONS: The combination of clinical findings and CRP is a useful tool to transition children with osteoarticular infections to oral therapy. Complicated outcomes were associated with higher early CRP at diagnosis and lower CRP at the end of parenteral therapy, suggesting that clinicians were more conservative with prolonged initial parenteral therapy in this group.
