A novel ultraviolet B home phototherapy system: Efficacy, tolerability, adherence, and satisfaction

Dermatol Online J. 2019 Feb 15;25(2):13030/qt3vn1z0s2.


Background: Phototherapy is effective in treating psoriasis and other skin conditions. However, clinic-based phototherapy can be time-consuming, expensive, and inconvenient. Conventional home phototherapy addresses many hurdles, but has other limitations.

Objective: Assess the treatment efficacy, adherence, and satisfaction of a novel ultraviolet B home phototherapy system.

Methods: Eight patients with stable plaque psoriasis completed a multicenter, prospective, open label, interventional study using a home phototherapy device designed to improve treatment control and adherence. Matched control and study lesions were assessed on each subject. A dosing protocol based on American Academy of Dermatology guidelines for narrowband UVB phototherapy was managed by the phototherapy system. Responsiveness to the treatment was measured using the Psoriasis Severity Index (PSI) at 10 weeks versus control. Patient satisfaction was graded on a five-star Likert scale.

Results: At 10 weeks, all patients experienced improvement in the treated lesions, with a mean improvement of 57% in PSI (P<0.0001 compared to baseline and P<0.0002 compared to the control lesions). Patient treatment adherence was 96% and treatment satisfaction was 100% five-star rated. Control lesions did not significantly change in PSI over the 10-week period (P=0.1411).

Conclusions: The home phototherapy system provided a safe and effective means to manage plaque psoriasis.
