Impacto de gastroenteritis severa por rotavirus en niños chilenos menores de 3 años de edad

Abstract: Rotavirus was responsible for nearly half of the severe gastroenteritis episodes among children <3 years, during a predominantly G4 serotype season. Every year, approximately one every 70 children <3 years will have a severe rotavirus gastroenteritis episode.

“…For rotavirus, these results are in line with 3 previous Chilean studies of ADE in these different settings. [21][22][23] The 26% to 30% proportion of rotavirus cases in the emergency department ADE is somewhat lower than the 34% observed in a previous study, 21 probably because the current age limit was 5 and not 3 years as in the previous study. A possible decline cannot be explained by rotavirus vaccines because in Chile vaccine use is restricted to a small private market.…”

“…In the case of Bolivia, few studies have been carried out on rotavirus genotyping, in which common genotypes have been detected and rare strains [88]. Research carried out in Chile indicates that unusual strains have appeared, which share homology with strains from Europe and Asia, like (G8 P [8]) [89,90,91]. In the case of Argentina, studies have been carried out where the G4 P [6] genotype has been detected in humans with segments of porcine origin (Table . 1.…”

“…No se ha dilucidado totalmente hasta ahora si estos cambios en el genotipo predominante se deben a una presión selectiva generada por estas vacunas o a fl uctuaciones naturales, pues en períodos previos a que estuvieran disponibles estas vacunas y en países donde no han sido incorporadas de manera programática, también se habían descrito variaciones regionales y temporales del tipo viral más frecuente 6,7 . En nuestro país, en la década de los ´90 se demostró un franco predominio de las variantes G1 en niños con GE 19 , mientras que estudios más recientes encontraron una mayor frecuencia, alrededor de 70%, de las variantes G4 20,21 .…”

“…Es destacable el claro predominio evidenciado para el genotipo G9P [8], que se identifi có aproximadamente en 2 de cada 3 casos en lactantes con infección rotaviral de 0-6 meses y 3 de cada 4 niños de 7-60 meses. Estudios realizados en nuestro país a mediados de la década de los ´90 describieron un predominio de las variantes G1, especialmente G1P [8] 19 , mientras que reportes posteriores, de mediados de la década pasada, evidenciaron una mayor frecuencia de las variantes G4 20,21 . Estas variaciones en el genotipo predominante serían producto de fl uctuaciones naturales e independientes del potencial efecto selectivo de las vacunas anti-rotavirus.…”
