Resumen
En 2011 se incorporó la vacuna 13-valente al Calendario Nacional de Inmunización, con aplicación efectiva desde 2012. El objetivo fue describir la epidemiología de la enfermedad y los factores de riesgo observados en pacientes con diagnóstico de enfermedad invasiva neumocócica en la población pediátrica que se atiende en el Hospital “Dr. F. Barreyro” y en el Hospital SAMIC-Oberá entre mayo de 2013 y abril de 2014. Se obtuvieron datos clínicos y epidemiológicos de los pacientes con diagnóstico confirmado y se realizaron técnicas de iología molecular para descartar y/o confirmar casos sospechosos. Se diagnosticaron 23 casos, con picos en invierno y primavera. Predominaron los pacientes mayores de 2 años (82%), los varones (65%) y las neumonías (69,6%). Los neumococos sensibles a penicilina preponderaron en todo el estudio. Se distinguieron dos serotipos (1 y 12F). No observamos prevalencia de factores de riesgo considerados. Es necesario continuar con la vigilancia activa.
The 13-valent pneumococcal conjugate vaccine was added to the National Immunization Program in 2011, and effectively administered since 2012. The aim of this study was to describe the post–vaccine epidemiology of pneumococcal invasive disease, in the pediatric population who come for consultation at the "Dr. F. Barreyro" and "SAMIC-Oberá" Hospitals, between May-2013 and April-2014. Clinical and epidemiological data were obtained and the suspected cases were confirmed by polymerase chain reaction. Twenty three cases were diagnosed, a seasonal pattern was observed with peaks in winter and spring. Patients older than 2 years old (82%), the masculine gender (65%), and who were diagnosed with pneumonia(69,6%) prevailed. Penicillin-sensitive pneumococci predominated throughout the study. Two serotypes (1 and 12F) were mainly distinguished. We did not observe any prevalence in the factors considered.It is necessary to continue active surveillance.
