Metabolic Syndrome and Inflammatory Cytokines in Psoriasis.

Obesity negatively affects the pathological states of chronic inflammation, such as Psoriasis and Psoriatic Arthritis. The inflammatory cytokines released by the adipose tissue determine, in addition to inflammation, a condition of insulin resistance, which is also a comorbidity of psoriasis. The state of chronic inflammation unites both psoriasis and obesity. The first is an autoimmune skin disease, where very thick skin layers are evident due to an abnormal proliferation of keratinocytes; obesity, on the other hand, represents one of the possible comorbidities of psoriasis the simultaneous presence in the same subject of two or more diseases.
