Resumen
El nuevo coronavirus SARS-CoV-2 parece tener una menor agresividad sobre la población pediátrica en comparación con la adulta. Sin embargo, más recientemente, al incrementar el número de pacientes pediátricos diagnosticados se ha podido observar el desarrollo de un síndrome de respuesta inflamatoria multisistémica potencialmente asociado a COVID 19 en niños. Nuestro objetivo fue recuperar y sintetizar los reportes que han descrito el síndrome de respuesta inflamatoria multisistémica potencialmente asociado a COVID 19 en niños. Se realizó un estudio de revisión de tipo narrativo de la literatura científica publicada en PubMed desde el 1 de enero 2020 al 30 de junio 2020. Los términos de búsqueda fueron síndrome inflamatorio multisistémico, Kawasaki, niños, COVID-19. El nuevo síndrome se ha asociado con una mayor dificultad para tratar a los niños con COVID-19 y se han observado algunas muertes secundarias a ello. Pero por el otro lado, la inmunidad innata pediátrica, dada por IgM, y la rápida respuesta para generar células de memoria dependientes y no dependientes del centro germinal se hipotetiza por algunos autores que podría explicar en gran parte el comportamiento y la incidencia de la nueva infección por SARS-CoV-2.
Abstract
The new SARS-CoV-2 coronavirus appears to be less aggressive in the pediatric population in comparison to the adult population. Yet, most recently, as the number of diagnosed pediatric patients with COVID-19 has increased, clinicians have observed the development of a multisystemic inflammatory response syndrome that is potentially associated with COVID-19 in the pediatric population. Our objective was to retrieve and synthesize the reports that have described the multisystemic inflammatory response syndrome potentially associated with COVID-19 in the pediatric population. We conducted a narrative review of scientific literature reported in PubMed from January 1st to June 30th, 2020, with the terms multisystem inflammatory syndrome, Kawasaki, children, COVID-19. This new syndrome has been associated with greater difficulty in treating children with COVID-19 and some deaths have been observed as a result. On the other hand, innate pediatric immunity, primarily driven by IgM, and the rapid immune response to generate germ-center dependent and non-dependent memory B cells as it has been hypothesized for other authors could largely explain the behavior and incidence of the new SARS-CoV-2 infection in the pediatric population.
