BACKGROUND Nail psoriasis has a major negative impact on the physical and psychological aspects of the patient's life. Treatment is often unsatisfactory because of the difficult penetration of the drug into the nail. OBJECTIVE To compare the efficacy of fractional CO2 laser monotherapy versus combined fractional CO2 laser and calcipotriol/betamethasone ointment preparation in treatment of nail psoriasis. PATIENTS AND METHODS Thirty patients with nail psoriasis with at least 2 affected fingernails were recruited for this study. Target NAPSI (tNAPSI) score was calculated at the start of the study and at 3 months after the last laser session. One affected fingernail of each patient received 6 sessions of fractional CO2 laser with 4-week intervals. Another affected fingernail of each patient received topical betamethasone/calcipotriol ointment once daily in addition to the 6 fractional CO2 laser sessions. RESULTS In the monotherapy group, there was significant improvement in the nail matrix score, nail bed score, and tNAPSI score. In the combined therapy group, there was significant improvement in nail bed score and tNAPSI score, but nail matrix score showed no statistically significant improvement. Overall, there was no statistically significant difference between the 2 studied groups. CONCLUSION Fractional CO2 laser can be an effective and promising new treatment for nail psoriasis.
