Abstract
BackgroundPediatric bone and joint infections account for one of the major causes of childhood morbidity. Disseminated sepsis being a systemic disorder with multisystem involvement, overshadows the timely recognition of bone and joint infections. Hence, we did this cross sectional study to evaluate the prevalence of septic arthritis and osteomyelitis in disseminated sepsis in children, the organisms implicated, and their antibiotic sensitivities.MethodsWe prospectively collected data from 1st July 2016 to 31st September 2017 of children aged less than 12 years with disseminated sepsis, i.e., patients with fever and two or more sites of focal infection of anatomically non-contiguous tissues.ResultsFifty-four patients of disseminated disease were included, of which 25 patients (46.3%) had osteoarticular infections. Septic arthritis was seen in 17 patients, and osteomyelitis was seen in 12 patients. The most common joint was hip (41.6%), and the most common bone involved was femur (53.8%). Blood culture showed MRSA in 28% and MSSA in 20%. Joint and bone aspirates showed S. aureus in 56% with 28% of MRSA and MSSA each. All Staphylococcus aureus organisms were found sensitive to vancomycin and teicoplanin. The mean values of CRP, duration of stay and duration of intravenous antibiotic was higher in MRSA infected patients compared to MSSA patients.ConclusionsStaphylococcus aureus is the most prevalent organism in musculoskeletal infection in disseminated sepsis children, with vancomycin sensitivity of 100% and methicillin sensitivity of 46.2% only. Cases of osteoarticular involvement with MRSA were higher compared to MSSA among the cases of disseminated disease. The prevalence of osteoarticular involvement is high in disseminated sepsis in children and increased clinical suspicion for such must be maintained.
