Devices for treatment of nail psoriasis.

Abstract

Nail psoriasis (NP) affects a significant proportion of cutaneous psoriasis patients, often leading to functional impairment and psychosocial distress. Despite available treatment options, challenges persist in achieving efficacy and with drug delivery, prompting investigation into novel therapeutic devices. A literature search was performed using the PubMed database for devices and lasers for NP on 17 October 2023 using the following search terms: device OR laser AND "nail psoriasis." Twenty-two articles were included describing treatment with pulsed dye laser, fractional carbon dioxide (CO<inf>2</inf>) laser, long-pulsed Nd:YAG laser, excimer laser, photodynamic therapy, intense pulsed light, and microneedling device. While some recent studies on use of therapeutic devices have shown promising results for NP treatment, current evidence supports an algorithmic approach including topical therapies, intralesional kenalog injections, and systemic therapies, depending on number of nails affected, presence of psoriatic arthritis, cutaneous psoriasis, comorbidities, and effect on quality of life. Laser therapy, although promising, requires further validation through extensive randomized trials before its inclusion in treatment regimens. These exploratory findings highlight emerging therapies that may expand the spectrum of options available. Use of lasers for NP treatment could provide dermatologists with a broader arsenal for customizing treatment plans that address individual patient needs, taking into account comfort, cost, and compliance to enhance overall patient outcomes.
