Pediatric Invasive Pneumococcal Disease in the United States in the Era of Pneumococcal Conjugate Vaccines

Abstract: SUMMARY Invasive infections caused by Streptococcus pneumoniae continue to be a major cause of morbidity and mortality worldwide, especially in children under 5 years of age. In the United States, 90% of invasive pneumococcal infections in children are caused by 13 serotypes of S. pneumoniae . The licensure (in 2000) and subsequent widespread use of a heptavalent pneumococcal conjugate vaccine (PCV7) have had a significant impact on decreas… Show more

“…Introduction of the seven-valent pneumococcal conjugate vaccine (PCV7) in the USA in 2000 and, later, in other countries has strongly reduced the incidence of PCV7 vaccine serotype invasive pneumococcal disease (IPD) there [1][2][3]. At the same time, a growing rate of non-PCV7 vaccine serotypes, primarily serotype 19A, has been documented among circulating pneumococci in the post-PCV7 period [4,5].…”

“…Históricamente Hib fue una importante causa de morbimortalidad en este grupo etario; sin embargo, después de la introducción universal de la vacuna conjugada, esta etiología prácticamente ha desaparecido 1 . En concomitancia con la disminución de enfermedad invasora por Hib, se detectó un aumento de la enfermedad invasora causada por S. pneumoniae, con una importante carga de enfermedad a lo largo del mundo, transformándose en la etiología más frecuente de BO en lactantes; se, aísla en 80-90% de los hemocultivos con crecimiento bacteriano y alcanza una mortalidad de 1,4% 1,8,9 . Debido a la carga de enfermedad neumocóccica y a su gravedad, se desarrollaron vacunas anti-neumocóccicas, en base a polisacáridos y conjugadas (PCVs), para incorporar a los programas de inmunización.…”

“…Debido a la carga de enfermedad neumocóccica y a su gravedad, se desarrollaron vacunas anti-neumocóccicas, en base a polisacáridos y conjugadas (PCVs), para incorporar a los programas de inmunización. La primera vacuna conjugada disponible internacionalmente fue la 7-valente (PCV7), que contiene a los serotipos 4, 6B, 9V, 14, 18C, 19F y 23F 8,10 . Posteriormente se desarrollaron vacunas con mayor número de serotipos, la PCV 10-valente (PCV10), que agregó a los serotipos 1, 5 y 7F y la PCV13-valente (PCV13), que además de los mencionados sumó los serotipos 3, 6A, 19A 8,[10][11][12] .…”

“…Pneumococci cause otitis media, pneumonia, bacteremia, and meningitis [1]. BHS is classified according to the Lancefield groupings of group A, B, C, F, and G. Group A beta-hemolytic streptococcus (GAS) is the most common causative agent of pharyngitis, which also causes immune-mediated poststreptococcal sequelaes, such as rheumatic fever and poststreptococcal glomerulonephritis.…”
