Most people with psoriasis have mild illness with minimal disturbance to activities of daily living. However, psoriasis can be a very serious condition with substantial comorbidity, including cardiovascular and metabolic disease; thus, an integrated approach to healthcare that targets skin problems, systemic inflammation, preventive health, and psychiatric care is imperative. Fortunately, the emergence of biologic agents and immunomodulators offers adjunctive treatment options as well as a better appreciation for the condition among clinicians and researchers.
