Es una enfermedad multifactorial, en la que personas gen\u00e9ticamente predispuestas, tras exponerse a diversos factores desencadenantes, desarrollan alteraciones en las v\u00edas inmunol\u00f3gicas que conducen su desarrollo.<\/p>\n

Adem\u00e1s, la importancia de la gen\u00e9tica est\u00e1 apoyada en una mayor incidencia en individuos con antecedentes familiares (en el 30-40% de los casos existen antecedentes familiares). El riesgo de tener psoriasis cuando los dos padres est\u00e1n afectos es mayor que\u00a0si solo uno esta afecto\u00a0o si se tiene un hermano afectado, pero es igualmente mayor al de la poblaci\u00f3n general.<\/p>\n

Los factores desencadenantes se dividen en externos e internos. Entre los factores externos se encuentran las agresiones f\u00edsicas sobre la piel, que inducen la aparici\u00f3n de nuevas lesiones, constituyendo el fen\u00f3meno de Koebner.<\/p>\n

Por \u00faltimo, entre los factores internos se encuentran las infecciones<\/a> (la m\u00e1s relacionada es la faringitis estreptoc\u00f3cica), los f\u00e1rmacos (litio, \u03b2-bloqueantes, interferones), el embarazo, el estr\u00e9s emocional y alteraciones endocrinol\u00f3gicas (obesidad). El tabaco se considera un factor de riesgo y agravante.<\/p>\n","protected":false},"excerpt":{"rendered":"\u00bfSabes qu\u00e9 es la psoriasis?
