Outcomes associated with the use of biologic agents in moderate to severe psoriasis

An estimated 2.1% of Americans have psoriasis and approximately 30% of them have moderate to severe psoriasis. Although the disease is not associated with mortality, it has a significant impact on health-related quality of life among patients. Several therapies are available for psoriasis including topical agents, phototherapy, and systemic medications. Recently, effective yet expensive biologic agents have been added as treatments for moderate to severe psoriasis. Biologics are recommended in patients for whom all other available treatment options have failed. This extensive review provides important information on the clinical and patient-related outcomes associated with the biologic agents used in psoriasis.
