Resumen
El asma grave es una enfermedad heterogénea y compleja que afecta aproximadamente al 5% de los pacientes con asma y se asocia a una importante carga de síntomas, exacerbaciones graves frecuentes e impactos negativos en la funcionalidad y calidad de vida. Diferentes estrategias de innovación han actualizado las opciones terapéuticas disponibles para estos pacientes, pero los anticuerpos monoclonales representan las alternativas con mayor relevancia clínica. Como especialistas en asma es importante mantenernos actualizados para poder identificar correctamente a aquellos pacientes que pueden beneficiarse del tratamiento con estos medicamentos. Este artículo ofrece una revisión actualizada y práctica enfocada en mepolizumab, un anticuerpo monoclonal humanizado anti-IL5 aprobado como tratamiento complementario en pacientes con asma grave eosinofílica. Los autores hemos realizado una síntesis de las evidencias de eficacia, seguridad y efectividad de mepolizumab con el objetivo de proveer una herramienta de consulta y apoyo en la toma de decisiones para el especialista que evalúa, diagnostica y trata pacientes con asma grave. Mepolizumab ha documentado en condiciones controladas de ensayos clínicos, y en estudios de vida real reducir consistente y significativamente las exacerbaciones de asma, mejorar el control de la enfermedad, mejorar la calidad de vida de los pacientes, y disminuir la dosis o retirar la exposición a corticoesteroides sistémicos.
