Background and Objectives
The current treatment options for alopecia areata (AA) typically aim to suppress inflammatory T-cell responses. Patients vary in their response to these treatments, and some do not respond to one or more types of therapy. Herein, we report the outcomes of combination therapy, employing fractional laser treatment and low-level light therapy (LLLT), with a focus on patients with recalcitrant AA.
Materials and Methods
LLLT (HEALITE II®; Lutronic, Goyang, Korea) and fractional laser treatment (StarluxTM 1540; Palomar Medical Technologies Inc., Burlington, MA, USA) were administered to the subjects every two weeks. Two dermatologists independently compared photographs taken at baseline and final follow-up visits and assessed the level of hair regrowth using a 5-point scale. The scale levels and their description are as follows: 0, no improvement; 1, < 25% (slight improvement); 2, 25-50% (moderate improvement); 3, 50-75% (marked improvement); and 4, 75-100% (most improvement).
Twenty patients (13 men and 7 women) were evaluated in this study. The mean improvement level was 2.55 points with 55% (n = 11) of patients showing > 50% improvement. No serious adverse events occurred, and treatment cessation was never deemed necessary.
Based on the results of this study, we propose that combination therapy may represent a viable new approach for the treatment of recalcitrant AA.
