Fractional CO2 laser in the treatment of nail psoriasis: how can it help?

Abstract

Treating nail psoriasis is often a time-consuming challenge with an unsecure outcome. Response to the treatment is variable and relapses are common. Systemic treatments have multiple systemic side effects and lack of the patient compliance makes intra-lesional therapies not the best choice for treatment of nail psoriasis. We aimed to evaluate and compare the efficacy and side effects of methotrexate versus calcipotriol plus betamethasone two-compound formula when applied topically to psoriatic nails after fractional CO2 laser. This comparative pilot study included 20 patients with nail psoriasis. One side was treated with fractional CO2 laser followed by the application of topical methotrexate (Group A) and the other side with fractional CO2 laser followed by topical (Calcipotriol 0.05 mg/gm + Betamethasone 0.5 mg/gm) (Group B). 4 sessions were done, once every 2 weeks. There was a high statistical significant decrease in total NAPSI score in group A at 1(P = 0.000) and 2 months (P = 0.000). There was a high statistical significant decrease in total NAPSI score in group B at 1(P = 0.001) and 2 months (P = 0.001). There was no statistical significant difference regarding total NAPSI score between both group A and B at 0 (P = 0.271), 1(P = 0.513) and 2 months (P = 0.647). Combined fractional CO2 laser with either topical MTX or topical betamethasone plus calcipotriol two-compound formula is effective treatment for nail psoriasis.

Ablative CO₂-Assisted Laser for Topical Drug Delivery in Nail Psoriasis: A Systematic Review

“…The results of our systematic literature review support the role of fractional laser treatment in the management of psoriasis while using topical medications. A total of 7 RCTs have been identified to date, out of which 4 were conducted as intra-patient studies [2,[10][11][12][13][14][15]. Despite the use of different topical medications and varying laser parameters across the studies, all of them have demonstrated a certain degree of reduction in NAPSI (although varying among the different studies).…”
