Microbiological characteristics of acute osteoarticular infections in children Free

Abstract

This study aimed to describe the microbiological characteristics of acute septic arthritis (SA) and osteomyelitis (OM) in children. Cases of children (0–15 years) with SA/OM were identified through a retrospective search of hospital discharge codes over a six-year period. In addition, a systematic literature search and meta-analysis of studies reporting culture results of children with SA/OM was performed. In our retrospective chart review, we identified 65 cases of OM and 46 cases of SA. The most frequently cultured organisms in both conditions were Gram-positive cocci, primarily . On admission, most patients had a normal white blood cell count (WCC) but elevated C-reactive protein (CRP) and/or erythrocyte sedimentation rate (ESR). Bacteraemia was associated with a longer mean length of hospitalization for both infections. Considering our results and the meta-analysis, we found low rates of culture-positivity in cases of clinically confirmed infection. In SA, articular fluid was culture-positive in 42.49 % [95 % confidence interval (CI) 28.39–57.23]. In OM, intra-operative samples were culture-positive in 52.65 % (95 % CI 30.54–74.22). Bacteraemia was detected in 23.91 % (95 % CI 8.40–44.24) of children with SA and 21.48 % (95 % CI 10.89–34.47) with OM. Despite appropriate sampling, a positive microbiological diagnosis is often lacking in paediatric acute osteoarticular infection using standard culture-based methods. This highlights the need for validation and use of more sensitive diagnostic methods, such as PCR.
