Pulsed dye laser therapy may be an attractive new option for treating nail psoriasis, according to Dr. Veronique Blatiere.
Nail psoriasis is challenging to treat because the psoriatic disease process damages the nails while they are still being formed. But Turkish investigators have reported positive results with three once-monthly pulsed dye laser (PDL) treatment sessions in a small uncontrolled patient series, Dr. Blatiere reported at the annual congress of the European Academy of Dermatology and Venereology.
Dr. Yasemin Oram and coworkers at the American Hospital in Istanbul, Turkey, reported on five patients with nail psoriasis treated using PDL. The laser therapy was applied at 595 nm with a pulse duration of 1.5 milliseconds, a beam diameter of 7 mm, and an energy fluence of 8-10 J/cm2. A treatment session was continued until a purple discoloration appeared.
Nail bed lesions, particularly onycholysis and subungual hyperkeratosis, responded to PDL better than did nail matrix lesions. After three treatment sessions, the average Nail Psoriasis Severity Index (NAPSI) score for nail bed lesions dropped from 14.8 to 8.
While the Turkish report is certainly encouraging, it should be viewed as a proof of concept pilot study, said Dr. Blatiere of Saint Eloi University Hospital in Montpellier, France. It needs confirmation with larger numbers of patients, a control arm, and blinded investigator assessment.
