 en Chronic ulcers: an integration model of vascular, immunological & infectious pathologies

Abstract

Chronic ulcers are those that do not heal during a long period of time. They are characterized by necrosis of the injured tissue with a purulent center and bleeding, being a painful condition. They are caused by an exaggerated inflammatory response producing major damage in the tissue and interfering with cicatrization. This model shows the relationship between the effects caused by vascular problems (venous and/or arterial), those caused by infectious agents ( Mycobacterium ulcerans check for this species in other resources ) and the immunological alterations that happen as a consequence of the evolution of the ulcer (unbalanced profile of proinflamatory and anti-inflammatory citocines), leading to a chronic process of inflammation retarding cicatrization of the ulcered tissue.

 es Úlceras crónicas: modelo de integración entre patología vascular, inmunológica e infecciosa

Resumen

Se conocen como úlceras crónicas aquellas heridas que no cicatrizan en un período largo de tiempo, caracterizadas por presentar un área necrótica en el sitio de lesión con un centro purulento y sanguinolento, causando dolor en la persona que la padece. Causan una respuesta inflamatoria crónica produciendo un daño mayor en el tejido y evitando la cicatrización del mismo. Planteamos un modelo que relaciona la gravedad de las úlceras vasculares (venosas y/o arteriales), infecciosas ( Mycobacterium ulcerans check for this species in other resources ) y las asociadas a alteraciones inmunológicas (desbalance entre el perfil de citocinas proinflamatorias y antiinflamatorias), lo que conlleva a un proceso de inflamación crónica evitando la cicatrización del tejido ulcerado.

Palabras-clave
úlcera crónica, citocinas, cicatrización, Mycobacterium ulcerans
