Long-term prognosis in patients with psoriasis

Psoriasis is a chronic, inflammatory, immune-mediated skin disease associated with substantial comorbidity. Traditional comorbid conditions include psychological/psychiatric disorders, psoriatic arthritis and inflammatory bowel disease. Increasingly, an association with metabolic dysfunction, including Obesity and the metabolic syndrome, and cardiovascular disease, with consequent effects Oil morbidity and mortality, has been recognized in psoriasis. The underlying inflammatory mechanisms of both psoriasis and psoriasis-associated comorbidities involve mediation by proinflammatory T-helper type 1 cytokines. For effective management of psoriasis and related comorbidides, an integrated approach targeting both cutaneous and systemic inflammation may be beneficial, and strategies to improve overall management of the patient should be encouraged to reduce the disease burden. This paper discusses the emerging role of biological agents in this approach, and offers an appreciation of the role of existing anti-psoriasis and adjunctive therapies.
