Empiema pleural por Streptococcus grupo anginosus en un preescolar y revisión de la literatura: Case report and review

Abstract

Empiema pleural por Streptococcus grupo anginosus en un preescolar y revisión de la literaturaStreptococcus anginosus pleural emphyema in a child. Case report and review Left pneumonectomy in a child with congenital pulmonary malformation was performed two months prior to admission. Within one week he had high fever. Chest CT scan showed massive left pleural effusion. Both Streptococcus anginosus group and Prevotella spp. grew from the fluid obtained by pleural punction. Antimicrobial therapy was immediately initiated with clindamycin and penicillin. Streptococus anginosus group is quite confusing in terms of classification and taxonomy. Now it is well recognized that three species belong to this genera: S. anginosus S. constellatus and S. intermedius. They all are considered normal flora of the oropharynx, nasopharynx, gastrointestinal tract and vagina but also they have been identified as agents of suppurative infections in children and adults. Many reports show adequate response to penicillin, however there is some emerging resistance in strains isolated in other studies. In this article we also suggest some diagnostic and microbiologic recommendations.

Complicated Pneumonia With Empyema Caused by Streptococcus Anginosus in a Child

“…6,14,15 Empyema in the fibrinopurulent or organizing stage should be considered an indication for surgical management. 16 The antibiotic course is usually long, with a mean duration of up to 34 days, and most SAG isolates seem to be sensitive to penicillin and cefotaxime, 10,17,18 like in our case report. Some reports indicate that patients infected by S. anginosus can be co-infected by other agents, including anaerobes, so clindamycin was added at the begin of the treatment.…”

“…20 Our case appears to be one of the very few published cases reporting a pneumonia caused by S. anginosus in the pediatric age group; the only other similar case found was a report of a Chilean child. 18 However, the authors found this difficult to confirm, as the term SAG is usually used instead of the actual member of the group. Also, this agent is often responsible for other types of infection in these ages.…”

Sepsis por Streptococcus anginosas originada en cáncer de colon abscedado: Reporte de un caso

“…Los S. grupo anginosus se caracterizan por formar colonias pequeñas y pueden tener antígenos de Lancefield, A, C, G o F. Antes se les conocía como S. milleri 1 .…”

“…En cuanto a su sensibilidad antimicrobiana, el grupo Streptococcus grupo anginosus tiene una buena sensibilidad in vitro y en los reportes clínicos, a penicilina y a cefalosporinas de tercera generación, aunque están surgiendo comunicaciones de resistencia a penicilina que pueden llegar al 33% 1,5 .…”

Streptococcus grupo anginosus: ¿Es su identificación clínicamente importante?

“…Por este motivo no es sorprendente que este grupo esté compuesto por microorganismos que son muy diferentes en morfología, en reacciones hemolíticas y en participación en procesos infecciosos. A este grupo pertenecen varios subgrupos de Streptococcus y uno de estos subgrupos es el grupo anginosus (Tabla 2 del artículo de P. Pidal 1 ).…”
