Fractional CO 2 Laser versus Fractional CO 2 Laser Plus Betamethasone/Calcipotriol Ointment in the Treatment of Nail Psoriasis.

Abstract

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. To compare the efficacy of fractional CO 2 laser monotherapy versus combined fractional CO 2 laser and calcipotriol/betamethasone ointment preparation in treatment of nail psoriasis. 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 CO 2 laser with 4-week intervals. Another affected fingernail of each patient received topical betamethasone/calcipotriol ointment once daily in addition to the 6 fractional CO 2 laser sessions. 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. Fractional CO 2 laser can be an effective and promising new treatment for nail psoriasis.
