RESUMEN
Resumen Los pacientes con Inmunodeficiencias primarias (IDP) tienen un riesgo elevado de complicaciones severas por la vacuna BCG, incluso mortalidad. Es necesario evaluar periódicamente el riesgo versus beneficio de la vacunación universal BCG en el periodo neonatal. Chile es un país con baja incidencia de tuberculosis (TB) pero cuya epidemiología ha cambiado recientemente con un aumento de los casos. Cambios en esquemas de vacunación BCG en países con incidencias mayores o similares de TB y con coberturas de vacunación menores han sido posibles sin aumento de los casos graves de TB que son los que previene la BCG. El cambio ha evitado complicaciones graves en pacientes con IDP. Creemos que un análisis crítico de la fecha de vacunación BCG debe realizarse hoy en Chile. Más aún dada la posibilidad técnica de realizar screening neonatal de IDP.
ABSTRACT
Abstract Patients with Primary Immunodeficiencies (PID) are at a higher risk of developing severe morbidities and mortality due to the administration of BCG vaccine. Risk-to-benefit of universal BCG vaccina tion of newborns must be assessed periodically. Chile has a low incidence of tuberculosis (TB) but the local epidemiology has recently changed with an increase of TB cases. Changes in the BCG vaccine schedule have been made in countries with similar or higher TB incidences and lower BCG vaccine coverage, with no increase in the severe TB cases, which are prevented by BCG. These changes have prevented serious complications in PID patients. We propose a critical analysis of the BCG adminis tration date in Chile due to the technical possibility of performing neonatal PID screening.
