Descripción de 3 casos de infecciones de piel y tejidos blandos por Streptococcus pneumoniae

Abstract

The role of Streptococcus pneumoniae as a causative agent of skin and soft tissue infections (SSTI) is unusual and its clinical interpretation is difficult. We describe here three cases of SSTI due to S. pneumoniae in patients admitted to the Provincial Pediatric Hospital of Misiones, Argentina that were detected during 10 years of invasive disease (ID) surveillance documented in 2010, 2011 and 2015. These cases involved two girls aged 8 and 7 months old, and a two-year-old male child with diagnoses of gluteal abscess, preseptal cellulites and pyoderma respectively. All the patients were eutrophic and in good general condition on admission; one of them was seropositive for HIV. Antimicrobial susceptibility and serotypes were framed within the local epidemiology of invasive pneumococcal disease. Despite its low frequency, S. pneumoniae as an etiological agent of SSTI must be considered. Our findings revalue the role of the diagnostic laboratory and contribute to document the behavior of this pathogen.

Skin and soft tissue infection caused by Streptococcus pneumoniae: report of 15 cases

“…Todas las cepas fueron sensibles a cefalosporinas DISCUSIÓN Se estima que el 2,2 % de las infecciones neumocócicas son de piel y partes blandas [7]. En los últimos años se han descrito casos de forma esporádica [8,9]. La mayoría ocurrieron en pacientes que presentaron patologías de base como quemaduras, diabetes mellitus, cáncer, VIH o alcoholismo [4].…”

“…El origen de las IPPBs neumocócicas no se conoce bien. Se ha especulado que puedan estar relacionadas con contaminaciones de origen respiratorio del propio paciente, de sus cuidadores o del personal sanitario [9,10]. Otros autores sugieren la diseminación del microorganismo desde un foco respiratorio a través del tejido celular subcutáneo hasta la piel, o la diseminación hematógena hasta estructuras musculoesqueléticas, produciéndose celulitis en las zonas adyacentes [11].…”
