Abstract
BACKGROUND: Treatment of nail psoriasis remains a challenging and often disappointing situation. OBJECTIVE: To compare the efficacy, adverse reactions and tolerability of treatment of nail psoriasis with PDL vs. Nd:YAG, in association with betametasona calcipotriol gel. METHODS: An open, prospective intrapatient left-to-right study was designed. The right hand of each patient received treatment with PDL and the left hand with Nd:YAG. Betamethasone calcipotriol gel was applied once a day during the first week after each laser session. A total of four sessions were administered. RESULTS: The clinical efficacy was evaluated according to the NAPSI score. All patients showed improvement in nail bed and nail matrix psoriasis. The global NAPSI mean declined in 15.46 (p<0.000). There was neither statistical difference between the reduction in nail bed and matrix NAPSI nor in the treatment with PDL vs. Nd:YAG. The administration of Nd:YAG was more painful. No serious adverse effects were documented. LIMITATIONS: No random assignment and the small number of patients. CONCLUSIONS: PDL and Nd:YAG have proven to be an effective treatment for nail psoriasis with no serious adverse effect. No statistically significant difference was found between the two treatments.
