ABSTRACT

Pruritus is a symptom that may be associated with a wide array of diseases - skin diseases, systemic diseases or even those without a defined cause. According to its severity and evolution, it may compromise the patients' quality of life in a significant way. New therapeutic approaches, in which histamine release is not the main event, are being described for pruritus control. Therefore, taking into account the origin of the mediators of pruritus, we conducted a review of the available resources emphasizing that, although very important, anti-histamines are not the answer for every kind of pruritus.


Prurido é um sintoma que pode estar associado a uma gama ampla de patologias, sejam elas cutâneas, sistêmicas ou mesmo sem causa definida . Conforme sua intensidade e evolução pode comprometer de forma significativa a qualidade de vida dos pacientes. Novas abordagens terapêuticas estão sendo descritas para o controle do prurido, onde a liberação da histamina não é o fator principal. Assim, baseando-se na origem de seus mediadores, faz-se uma revisão desses recursos e ressalta-se que, embora de grande importância no arsenal terapêutico, os anti-histamínicos não são a panacéia para todos os tipos de prurido.

ABSTRACT

El prurito es la causa más común de consulta en Dermatología. En el presente articulo se hace una revisión de los estudios más relevantes sobre el prurito y se revisan la fisiopatogenia y la relación con enfermedades de distinto tipo. Es importante recalcar la relación entre el prurito y la respuesta del SNC, en lo que se ha llamado la inflamación neurobiológica. Establecemos una forma racional de enfrentar el prurito tanto desde el punto de vista de laboratorio como de terapéutica.

ABSTRACT

El prurito es un síntoma relativamente frecuente, que reconoce numerosos y diversos factores desencadenantes, que actúan a través de mecanismos fisiopatológicos muy variados pero no bien precisados. El prurito puede instalarse sobre una piel previamente sana. Estos casos corresponden a los llamados pruritos primarios, esenciales o médicos. Por el contrario, cuando el prurito afecta una piel con lesiones (previas al gratage y a sus consecuencias) se habla de prurito secundario y dermatológico, el que de hecho corresponde a dermatopatías pruriginosas.
