Investigadores del Nottingham City Hospital evaluaron el efecto de 500 mg diarios de vitamina E natural comparado con placebo en la sintomatología asmática de 72 adultos, que continuaron recibiendo al menos una dosis diaria de corticosteroide inhalado. Los parámetros de evaluación fueron los cambios en la capacidad respiratoria, puntuación de síntomas, uso de broncodilatadores y niveles séricos de IgE.
A pesar de que el aumento del consumo dietético de vitamina E se ha asociado a una menor incidencia del asma y que combinaciones de antioxidantes que contenían vitamina E han sido efectivas en la reducción de la broncoconstricción inducida por ozono, en este nuevo estudio no se observaron diferencias en los parámetros de evaluación entre el grupo que recibió vitamina E y el grupo placebo tras las seis semanas.
