Psoriasis is a multifactorial disease that can be related to genetic, environmental and immunological causes. Therefore, not only a single factor but different aspects contribute to the onset of the disease, varying from individual to individual. It would be characterized by an abnormal proliferation and differentiation of keratinocytes, mediated by a dysregulation in the auto-immune T cell response in which several cytokines participate, including Interleukin (IL)-17, IL-17A, IL-12, IL-22, IL-23. These cells and cytokines are responsible for the aggression on skin cells, inflammation and accelerated reproduction of the cells of the epidermis. Due to the chronic inflammation, psoriasis is frequently associated with other concomitant non-dermatological morbid conditions such as arthropathy which can be complicated by a disabling evolution. Psoriasis is also frequently associated with comorbidities such as Cardiovascular Diseases (CVD), hyperlipidemia, diabetes and obesity.
The knowledge of common inflammatory pathways and of the potential links between psoriasis and other diseases should encourage dermatologists to a multidisciplinary approach to psoriasis and to an optimal management also in the light of new therapeutic possibilities.
