RESUMEN

Introduccion:

La enfermedad neumococica es una de las principales causas de mortalidad infantil en el mundo. Ob je - tivo Determinar los serotipos de Streptococcus pneumoniae que producen enfermedad invasiva en ninos menores de 5 anos en Venezuela. Materiales y

Metodos:

Se establecieron 7 hospitales centinelas. El estudio incluyo variables demograficas y epidemiologicas. El Instituto Nacional de Higiene Rafael Rangel realizo la confirmacion y serotipificacion de las cepas.

Resultados:

Entre 1999-2007 fueron se - ro tipificadas 493 cepas de S. pneumoniae. Los serotipos mas frecuentes fueron el 14 (34,9%), 6B (13,8%), 5 (9,1%), 1 (6,1%) y 19A (6,1%), que correspondieron al 70% de las cepas. La cobertura global de la vacuna polisacarida conjugada heptavalente seria de 66,9% en bacteriemias, 56,6% en neumonias y 64,6% en meningitis. La va cuna decavalente tendria una cobertura teorica global de 76,9%, con valores similares en las tres entidades clinicas y la trecevalente tendria una cobertura potencial teorica de 90%. Conclu sio - nes Esta investigacion reporta la distribucion de los serotipos invasivos de S. pneumoniae en Venezuela y permiten in ferir que la introduccion de vacunas neumococicas conjugadas en nuestra poblacion pediatrica ten drian un impacto positivo en la prevencion de la enfermedad.
ABSTRACT

Background:

Pneumococcal disease is the principal cause of morbidity and mortality in children.

Objective:

To determi - ne the serotype distribution of invasive S. pneumoniae strains isolated from children under 5 years in Venezuela. Ma terials and

Methods:

7 hospitals settled down sentries. The study included demographic variables and epidemiologists. The National Institute of Higiene gRafael Rangelh rea li - sed the confirmation and serotyping of the strains.

Results:

Bet ween 1999-2007 493 strains of S. pneumoniae were se - ro typing. The most frequent serotypes, with 70% of all the strains belonging to these 5 serotypes were 14 (34,9%), 6B (13,8%), 5 (9,1%), 1 (6,1%) and 19A (6,1%). The potential co verage of the 7-valent conjugate vaccine is 66,9% for bacteriemia, 56,6% for pneumonias and 64,6% for meningitis respectively. The potential coverage of the 10-valent conjugate vaccine is (76,9%) with similar values for the three clini cal manifestations and the 13-valent has a potential coverage of 90%.

Conclusions:

This investigation reports the distribution of invasive S. pneumoniae serotypes in Venezuela and allow to infer that the conjugated vaccines introduction in our pediatric population could have a positive impact on the prevention of pneumococcal disease.
