Phototherapy in Psoriasis: A Review of Mechanisms of Action
No full textBACKGROUND: Phototherapy is one of the most efficacious treatment options for psoriasis. New, emerging studies are beginning to define the biological mechanisms by which phototherapy improves psoriasis. METHODS: To provide an overview of the mechanisms thought to be responsible for the therapeutic effects of phototherapy, a review was performed on all relevant published studies in the Medline database from January 1st, 1985 to August 15th, 2011. FINDINGS: Four categories of action were proposed in the literature to describe the effects of phototherapy in psoriasis: 1) alteration of cytokine profile, 2) induction of apoptosis, 3) promotion of immunosuppression, and 4) all other mechanisms. CONCLUSIONS: Phototherapy acts through a combination of pathways to confer therapeutic benefits in psoriasis, and these different modalities may help explain its particular usefulness in treating this cutaneous disease
