Declining prevalence of Methicillin-resistant Staphylococcus aureus septic arthritis and osteomyelitis in children: implications for treatment

Abstract: OBJECTIVES To assess clinical characteristics and differences in outcomes between children with Methicillin-resistant Staphylococcus aureus (MRSA) and Methicillin-sensitive Staphylococcus aureus (MSSA) osteomyelitis or septic arthritis and whether initial antibiotic regimen affects patient outcomes.STUDY DESIGN We analyzed records of children ages 15 days to 18 years admitted between 2009 and 2016 to two tertiary children’s hospitals who were diagnosed with an osteoarticular infection and had a microorganism i… Show more

“…1,2 In children and adolescents, the bones most commonly involved include the long-bones of upper and lower extremities, with osteomyelitis of the vertebral bodies of the spine being much less common, accounting for only 1%-2% of osteomyelitis episodes in children. 3,4 Osteomyelitis is commonly due to pyogenic bacteria with Staphylococcus aureus accounting for 32%-67% of cases among all ages. 1,[3][4][5][6] Among pediatric populations, S. aureus and Streptococcus species, including Group B Streptococcus, are the predominate pathogens.…”

“…aureus es el principal agente etiológico, es identificado en más del 50% de los cultivos positivos. 5 En las últimas dos décadas, las infecciones osteoarticulares causadas por SAMR presentaron un incremento mientras que las tasas de infecciones causadas por Staphylococcus aureus sensibles a la meticilina (SAMS) se habían mantenido estables. 5 Sin embargo, recientemente se ha demostrado una disminución de la proporción de infecciones causadas por SAMR y un incremento de las causadas por SAMS.…”

“…5 En las últimas dos décadas, las infecciones osteoarticulares causadas por SAMR presentaron un incremento mientras que las tasas de infecciones causadas por Staphylococcus aureus sensibles a la meticilina (SAMS) se habían mantenido estables. 5 Sin embargo, recientemente se ha demostrado una disminución de la proporción de infecciones causadas por SAMR y un incremento de las causadas por SAMS. 5 Las infecciones por SAMR se han asociado con marcadores inflamatorios elevados, complicaciones, estancia hospitalaria prolongada y costos hospitalarios altos; sin embargo, en un estudio retrospectivo del 2009-2016 realizado por Weiss y colaboradores, 5 se analizaron los datos de 584 casos con infección osteoarticular confirmada y al comparar los aislamientos de SAMR y SAMS, no encontraron diferencias estadísticamente significativas en los marcadores inflamatorios y hospitalización en ambos grupos.…”
