Assessing the Efficacy of Monthly 308 nm Excimer Lamp Double-Stacked Pulse Adjusted Therapy for Alopecia Areata. Skin Appendage Disord 2024; 10:18-25. [PMID: 38313573 PMCID: PMC10836865 DOI: 10.1159/000533993] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/22/2023] [Accepted: 09/01/2023] [Indexed: 02/06/2024] Open
Abstract
Introduction Alopecia areata (AA) is an autoimmune disease characterized by T cell-mediated attack on the hair follicle. Although there are a wide range of therapies, the majority of them are not satisfactory due to side effects, pain due to intralesional injections or limited efficacy. In this study, we sought to evaluate the efficacy, influence factors, and safety of 308 nm excimer lamp used in a monthly basis in a double-stacked pulse manner for the treatment of AA. Methods This was a prospective study, using 308 nm excimer lamp in a double-stacked pulse therapy for AA. The primary endpoint was the improvement in SALT score. Results A total of 40 patients with AA were enrolled in this study. Forty (100%) patients achieved clinical response. Hyperpigmentation and erythema occurred on the treated alopecic areas of all patients but they were considered tolerable. Patients of younger age or with a smaller area of affection had a better overall treatment response. Conclusion 308 nm excimer lamp therapy is an excellent option for single or multiple AA because it achieves a good clinical response with less adverse effects than other therapies. This therapy may be useful for low-income countries where new JAK inhibitors are not available, however, for patients with extensive hair loss, it is not as effective and thus, it may be unfit for patients with alopecia totalis and alopecia universals.

Single-cell transcriptome analysis of fractional CO 2 laser efficiency in treating a mouse model of alopecia. Lasers Surg Med 2022; 54:1167-1176. [PMID: 35916125 DOI: 10.1002/lsm.23590] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/01/2022] [Revised: 07/03/2022] [Accepted: 07/16/2022] [Indexed: 11/06/2022]
Abstract
OBJECTIVES Hair loss, including alopecia, is a common dermatological issue worldwide. At present, the application of fractional carbon dioxide (CO2 ) laser in the treatment of alopecia has been documented; however, the results vary between reports. These varying results may be due to the limited knowledge of cellular action in laser-irradiated skin. The objective of this study was to investigate the molecular and cellular mechanisms of laser treatment under effective conditions for hair cycle initiation. METHODS A fractional CO2 laser was applied and optimized to initiate the hair cycle in a mouse model of alopecia. Several cellular markers were analyzed in the irradiated skin using immunofluorescence staining. Cellular populations and their comprehensive gene expression were analyzed using single-cell RNA sequencing and bioinformatics. RESULTS The effective irradiation condition for initiating the hair cycle was found to be 15 mJ energy/spot, which generates approximately 500 μm depth columns, but does not penetrate the dermis, only reaching approximately 1 spot/mm2 . The proportion of macrophage clusters significantly increased upon irradiation, whereas the proportion of fibroblast clusters decreased. The macrophages strongly expressed C-C chemokine receptor type 2 (Ccr2), which is known to be a key signal for injury-induced hair growth. CONCLUSIONS We found that fractional CO2 laser irradiation recruited Ccr2 positive macrophages, and induced hair regrowth in a mouse alopecia model. These findings may contribute to the development of stable and effective fractional laser irradiation conditions for human alopecia treatment.

Abstract
BACKGROUND Photobiomodulation is a promising therapy for hair loss with negligible side effects. However, the reported effects of photobiomodulation therapy for hair loss are inconsistent. OBJECTIVE To assess the curative effect of photobiomodulation therapy for the treatment of hair loss. METHODS A systematic review of self-controlled studies and randomized controlled trials was conducted. ScienceDirect, PubMed, and Wiley Online Library were searched from the earliest date to May 30, 2021. RESULTS Thirty-six studies (966 patients) were included. Two to 4 meta-analyses with different indices were performed separately on 4 groups of studies to test the effectiveness of the following hair loss treatments: ultraviolet light for alopecia areata (AA), red light for androgenetic alopecia (AGA), infrared light for AA, and infrared light for AGA. All meta-analyses showed that treatments were superior to control ( p < .05). CONCLUSION The meta-analyses strongly suggested that photobiomodulation therapies with ultraviolet and infrared light were effective for treating AA, and photobiomodulation therapies with red light and infrared light were effective for treating AGA.

Comparison of the efficacy and safety of 308-nm excimer laser with intralesional corticosteroids for the treatment of alopecia areata: A randomized controlled study. Lasers Surg Med 2021; 54:502-510. [PMID: 34859460 DOI: 10.1002/lsm.23501] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/09/2021] [Revised: 10/18/2021] [Accepted: 11/16/2021] [Indexed: 12/24/2022]
Abstract
BACKGROUND Corticosteroids have been the mainstay of treatment for alopecia areata (AA). Recently, the 308-nm excimer laser has been proposed for treating AA. OBJECTIVES To compare the efficacy and safety of excimer laser with intralesional corticosteroid (ILCS) in AA. METHODS Patients with at least two alopecic patches were randomly assigned to receive weekly excimer laser treatments or monthly injections of ILCS. Photographs and trichoscopy images were examined at baseline, the last treatment session, and after one month of follow-up. The hair regrowth score was evaluated on a 6-point scale. RESULTS Sixteen patients with 99 alopecic patches completed the study. At the last treatment session, the mean score of hair regrowth for the laser was significantly lower than the ILCS (p = 0.003). However, after a month of follow-up, the difference was not statistically significant (p = 0.148). Positive response in hair regrowth (≥50%) was achieved in 47% of laser-treated patches and 66% in ILCS-treated ones. Four (25%) and 8 (50%) patients experienced severe adverse events of laser and ILCS, respectively. CONCLUSIONS The excimer laser was safe and effective in AA. The effect of laser on hair regrowth might be delayed as compared with ILCS.
