UVA-1 laser in the treatment of palmoplantar pustular psoriasis.Photomed Laser Surg. 2013 Sep; 31(9):434-8.PL
The purpose of this study was to assess the efficacy of monochromatic UVA laser in the treatment of palmoplantar pustular psoriasis (PPP).
UVA-1 laser (355 nm) has been reported to be safe and effective in the treatment of psoriasis, but the range of potential applications has not been fully explored.
Thirty-three patients were enrolled in an open prospective study. Patients were treated from two to four times weekly at a fixed dose of 80-140 J/cm(2). Follow-up was 3 months. Clinical remission was observed in all patients who completed the study, with limited side effects (mild post-treatment erythema).
We report for the first time that UVA-1 laser produces a therapeutic response in PPP.
