Prurito crónico

Ana María Villa-Arango, Margarita María Velásquez-Lopera, Ricardo Cardona


El prurito crónico se define como una sensación no placentera de la piel que induce el rascado y que dura más de seis semanas. Este síntoma puede ser la manifestación de una enfermedad cutánea o sistémica y compromete la calidad de vida de los pacientes, alterando de forma consistente el sueño y las actividades diarias. La fisiopatología es compleja e incluye múltiples mediadores y sus respectivos receptores, que a través de diferentes vías de señalización llevan información por las fibras nerviosas tipo C hacia el tálamo, desde donde se distribuye a diversas zonas de la corteza cerebral. La comprensión de estos mecanismos ha permitido identificar posibles blancos terapéuticos y el desarrollo de moléculas cada vez más efectivas y seguras para los pacientes. La presente revisión pretende dar una visión acerca del manejo diagnóstico y terapéutico de los pacientes con prurito crónico.
