In addition to musculoskeletal and cutaneous manifestations, patients with PsA have a higher prevalence of comorbidities compared to the general population. More than half of patients with PsA have at least one comorbidity, with up to 40% of patients having more than three comorbidities. PsA has a particularly strong association with metabolic diseases and, as a result, with cardiovascular diseases (CVD).

The prevalence of psoriatic arthritis is evidenced in the age range of 20-50 years, and both sexes are equally affected. PsA usually has a violent progression with osteo-articular mutilation.
