Although treatment with biologic agents can decrease the levels of inflammatory cytokines, the excimer laser has the ability to directly cause apoptosis of T cells and induce DNA damage in the antigen-presenting cells, which the authors attribute to the superior response observed from the excimer laser compared to ustekinumab.44. Cytokines produced from innate immune cells activate myeloid dendritic cells, which in turn present antigens and secrete mediators leading to Th17 and Th1 differentiation. The use of higher fluencies was reported to result in higher occurrences of blistering. Each of these protocols make use of different features of the patients’ psoriasis to help determine the optimal dosimetry when utilizing the excimer laser. Patients who were assessed in the aforementioned studies were often patients with mild to moderate psoriasis. 308-nm excimer laser for the treatment of psoriasis: induration-based dosimetry. This site needs JavaScript to work properly. The 308 nm can also be used in the treatment of mild to moderate plaque psoriasis in children. Finally, use of clobetasol spray and ointment in conjunction with the excimer laser resulted in a safer side effect profile, as well as improved clearance of lesions in the long term.30. Photodermatol, Photoimmunol, Photomed. Having used traditional light boxes in my practice for many years, I was somewhat skeptical about using excimer laser therapy for psoriasis. Fluency ranged from 0.5 MED (low) to 16 MED (high); one study demonstrated that medium to high fluencies yielded better improvement in fewer number of treatments. Single administration of lesion-limited high-dose (TURBO) UVB using the excimer laser: clinical clearing in association with apoptosis of epidermal and dermal T cell subsets in psoriasis. It must be noted however that the forehead, hairline, and retroauricular areas are not entirely covered by hair, and often treatment with the excimer laser is a viable option.36 Wong et al present a case of a 68-year-old female patient with generalized plaque psoriasis, also involving the hairline of the scalp. 2015;26:45–48. Overall, the 308 nm excimer laser is a very well tolerated treatment option for patients with psoriasis. Excimer laser treatment is highly effective in psoriasis, another T cell–mediated disorder that shares many immunologic features with AA.

Few adverse reactions have been reported, and they are consistent with adverse reactions associated with other forms of phototherapy including erythema, blistering, hyperpigmentation, and hypopigmentation (Figure 3). Taneja and colleagues innovated this method whereby an initial dose is based on the induration component of the modified PASI and subsequent doses are based on the change in induration. This protocol identifies the minimum dose at which the patient will blister, and then subsequent treatments are administered at doses less than the MBD. It is possible that this is all related to the different mechanisms of action for the excimer laser compared to more systemic or biologic agents. Excimer lasers provide the benefits of NB-UVB but can be used on smaller treatment areas, such as the elbow or knee, for particularly stubborn plaques of psoriasis. The XTRAC excimer laser is safe and effective, dermatologist recommended and covered by all major insurances. By the nature of the excimer laser, it is not as practical for monotherapy use in patients with severe plaque psoriasis, as the treatment field and practical application of the laser would make treatment a very time consuming and difficult process. After 5weeks, 1session per week, the condition significantly improved (Fig. J Am Acad Dermatol. The 308 nm excimer laser was initially studied for the treatment of moderate plaque psoriasis by Bonis et al in 1997. Guenther L. Current management of scalp psoriasis.
