A comparative study of different treatment frequencies of psoralen and ultraviolet A in psoriatic patients with darker skin types (randomized‐controlled study)

Abstract

Our study suggests reducing PUVA frequency and the cumulative UVA dose does not compromise the efficacy of PUVA, but it may improve its benefit/risk ratio. RESTRICTIONS: Few number of cases.

Comparison of turbo-PUVA and conventional American-style PUVA in the treatment of psoriatic patients

“…This conclusion was in accordance with that of the recent study of El‐Mofty et al . (25) who found that twice weekly PUVA treatment for psoriasis is at least as effective as treatment given more frequently, and may be safer, as lower cumulative UVA doses are required for clearance. It also allows for a more efficient operation of a PUVA unit and is more convenient for patients (26).…”

“…It also allows for a more efficient operation of a PUVA unit and is more convenient for patients (26). Fewer sessions/week means less disruption to the patient life, more compliance to treatment, and reduced costs (25, 27).…”

A review of phototherapy protocols for psoriasis treatment

“…66 A recent randomized controlled study of darker skin types proved the same in this group of patients, demonstrating that twice-weekly phototherapy maintains PUVA efficacy and may improve the riskbenefit ratio. 67 The use of maintenance PUVA is common despite limited data regarding the risks and benefits of this approach. A survey of dermatologists in France, Belgium, and the Netherlands was carried out to see how PUVA is employed in clinical practice and to determine whether safety guidelines are respected.…”
