- W2000402788 abstract "La enfermedad invasora neumocócica es una entidad grave y cuya incidencia parece en aumento. La endocarditis por Streptococcus pneumoniae es infrecuente, particularmente en niños sin factores de riesgo. Su caracterización etiológica resulta difícil ante cultivos negativos. Se presenta un niño de 17 meses, previamente sano, no vacunado frente a neumococo. Durante una neumonía tratada con betalactámicos aparecen deterioro cardiorrespiratorio progresivo y soplo cardíaco. La ecocardiografía transtorácica muestra una vegetación mitral. Se diagnostica endocarditis y se adecua la antibioterapia (cefotaxima, gentamicina y vancomicina, mantenidas 6 semanas). Los cultivos resultan negativos. Ante la no mejoría se interviene, colocándose una prótesis. En la válvula resecada, mediante técnica de reacción en cadena de polimerasa (PCR), se identifica S. pneumoniae. La evolución es buena, permaneciendo asintomático a los 6 meses de seguimiento. Debe considerarse la posibilidad de endocarditis como forma invasora de infección neumocócica en niños sin factores de riesgo, y la utilidad de la PCR para establecer su etiología ante cultivos negativos. Invasive pneumococcal infection is a severe disease and its incidence may be increasing. Endocarditis due to Streptococcus pneumoniae is uncommon, particularly in children without risk factors. Etiologic diagnosis is difficult when cultures are negative. We report the case of a previously healthy, 17-month-old boy not vaccinated against pneumococcus who, during the course of pneumonia treated with beta-lactam antibiotics, developed cardiorespiratory deterioration and heart murmur. Mitral valve vegetation was identified by transthoracic echocardiography. Endocarditis was diagnosed and new antibiotics were given for 6 weeks (cefotaxime, gentamycin and vancomycin). Cultures were negative. Because of lack of improvement, prosthetic mitral replacement was indicated. S. pneumoniae was identified by polymerase chain reaction (PCR) in the pathological specimen. Outcome was favorable, and the patient remained symptom-free after 6 months of follow-up. The possibility of endocarditis as an invasive pneumococcal infection should be considered in children without risk factors. PCR is a useful technique to establish the etiology when cultures are negative." @default.
