Although the laser has demonstrated clinical efficacy, there is a lack of literature outlining the safety, efficacy, and patient acceptability of the excimer laser. Several different treatment protocols have been developed and optimized to more effectively treat psoriatic lesions and to achieve greater improvements in the PASI score with fewer treatments. Photodermatol, Photoimmunol, Photomed. 2003;361:1197–1204. Quintessence Int. 2009;361:496–509. Over the years the excimer laser has evolved in its clinical usage, and appropriately, so have the treatment protocols that are used in clinical practice. 2001;137:95–96. •  Testimonials   COVID-19 is an emerging, rapidly evolving situation. Psoriasis is a skin problem caused by active immune system that caused excessive skin growth. The most commonly observed side effects are erythema, blistering, hyperpigmentation, and hypopigmentation.32 These side effects are typically observed only at the sites of treatment, they do not occur in all treatments, and are often well tolerated by patients. It became clear in assessing these various protocols that the most efficacious protocol was the MBD protocol, in which patients were treated all the way up to a sub-blistering starting dose, and followed accordingly with dose modulation as needed. 2015;20:5–7. The excimer laser was invented in 1970 by Nikolai Basov et al by using a xenon dimer (Xe2). 2016 Dec 12;6:165-173. doi: 10.2147/PTT.S105047. The three main protocols that were identified were the MED protocol, the Induration protocol, and the MBD protocol. For example, one study demonstrated improvement with 21 sessions.25,26, Adjunctive topical therapies can also be used to augment the laser’s results. ability to treat mi ld, moderate and eve n severe but localised. Bonis et al were the first to study the use of the 308 nm XeCl excimer laser in the field of dermatology in 1997. It means that the treatment will not work well for psoriasis cases that affect large parts of the body. Skin Therapy Lett. Nonetheless, even with a sub-blistering dose, patients tolerated the treatment very well and in clinical experience even the blistering and erythema are often well tolerated compared to their untreated psoriasis. All studies determined the initial treatment dose using either the minimal erythema dose (MED) or induration. It has a range of efficacies depending on the protocol used with several different treatment protocols, including the induration protocol, the minimal erythema dose protocol, and the newer minimal blistering dose protocol. This study suggests that nine sessions on average equating to a mean cumulative dose of 4.45 J UVB are adequate for complete plaque resolution. In addition to psoriasis, a vast number of other cutaneous diseases can also be treated with the excimer laser. Arch Dermatol. Scalp psoriasis, especially when involving the hairline, can cause significant impairment in quality of life due to its visibility. Excimer laser treatment is highly effective in psoriasis, another T cell–mediated disorder that shares many immunologic features with AA. Treatment of inverse psoriasis with the 308 nm excimer laser. 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. This laser focuses a single band of ultraviolet B (UVB) light on psoriasis sores. 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. Dermatol Online J. The excimer laser is superior in inducing T cell apoptosis in vitro compared with narrowband UVB, with paralleled improved clinical efficacy. This is a discussion that should be had with patients and clinicians before treatment. 2015;26:45–48. Because the laser light never touches the surrounding skin, it reduces the risk of UV radiation exposure. 1995;72–81. Feldman SR, Mellen BG, Housman TS, et al. The search results were included if they contained information pertaining to excimer laser and psoriasis treatment and description of the safety, efficacy, and patient acceptability of the treatment. USA.gov. Over 15 weeks the difference in mean modified PASI scores between the excimer laser-treated site and the control site was statistically significant (P<0.001) with the excimer treatment group showing substantial improvement and clearance.37, In another study by Morison et al 35 patients with scalp psoriasis who had failed prior intensive topical therapy were treated with the excimer laser. Levin E, Debbaneh M, Malakouti M, et al. excimer laser and clinical data on the treatment of psoriasis and vitiligo will be discussed. This again supports the viability of using the excimer laser in combination treatment with other treatment modalities for psoriasis.42, Furthermore, Dong et al demonstrated that combination therapy with the excimer laser and flumetasone ointment achieved greater improvements in PASI scoring than excimer laser monotherapy, with combination treatment patients achieving an average PASI improvement of 82.51 and excimer monotherapy patients achieving an average PASI improvement of 72.01. J Lasers Med Sci. Treatment for palmoplantar pustular psoriasis: systematic literature review, evidence-based recommendations and expert opinion. 8 They demonstrated that the cumulative dose for complete clearance was 6.47 times less with the excimer laser than with traditional NB-UVB and that the number of treatments … Dermatol Surg. A maintenance protocol for psoriasis plaques cleared by the 308 nm excimer laser. 308 nm UVB excimer laser 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. Compared to the MED protocol, the induration method allows for clinicians to modify the dose as plaques begin to change in response to treatment. The patient was then treated for 12 days following the initial treatment at a sub-blistering does of 800 mJ. Arch Dermatol. Several topicals have been studied including dithranol ointment, flumetasone/salicylic acid ointment, calcipotriol ointment, clobetasol spray, and calcitriol ointment.27–30 In one study by Rogalski et al, addition of dithranol ointment to the excimer laser protocol resulted in a reduced Psoriasis Area and Severity Index (PASI) score.27 Furthermore, use of flumetasone/salicylic acid ointment resulted in a lower cumulative UVB dose, as well as plaque improvement. Wong JW, Nguyen TV, Bhutani T, Koo JY. 308-nm excimer laser for the treatment of psoriasis: a dose-response study. 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. J Am Acad Dermatol. The PHAROS excimer laser is different from cosmetic lasers that are usually associated with pain during treatment and post-treatment downtime for the patient. When considering the excimer laser for the treatment of psoriasis, it has become apparent that appropriate patient selection must be made. psoriasis plaques and plays an important role in … The mechanism of action of the excimer laser, similar to the action of UVB light, induces apoptosis in keratinocytes and T lymphocytes. The stigmata of atopic dermatitis, including: erythema, infiltration, lichenification, excoriations and pruritus can severely impact a patient’s quality of life. This allowed researchers to achieve greater improvements in PASI score in a faster period of time. There were a variety of treatment protocols that were identified for the treatment of psoriasis with the excimer laser. The 308 nm excimer laser was initially studied for the treatment of moderate plaque psoriasis by Bonis et al in 1997. The combined analysis of these studies showed that $64 of patients with palmoplantar pustular psoriasis experienced an improvement of at least 70% at the end of treatment. Am J Ophthalmol. 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. The treatment protocol used in that study involved stepwise dose increments similar to conventional phototherapy. Objective: To characterize treatment parameters for 308 nm excimer laser phototherapy. The patient was subsequently treated with high-dose excimer laser therapy and demonstrated a rapid improvement in PASI scoring. 1997;350:1522.

This makes the excimer laser a viable treatment option for patients with palmoplantar pustular psoriasis.40,41, Another advantageous aspect of the excimer laser is that it can be used in combination with other treatment modalities, and these often have a synergistic effect. Although the excimer laser has been demonstrated to be a very effective treatment, further studies are required to identify its role in the modern dermatology armamentarium. In 1997, Bonis et al 7 also reported that the 308-nm XeCl excimer laser was useful in the treatment of psoriasis. The excimer laser has been adopted by other medical disciplines such as cardiology, dentistry, and orthopedics.12–14. The XTRAC laser is a type of excimer laser that uses ultraviolet light to treat many forms of psoriasis. The 308 nm excimer laser is a widely used device throughout the field of dermatology for many diseases, including psoriasis, vitiligo, hypopigmented disorders, alopecia areata, atopic dermatitis, and in many other dermatologic diseases such as cutaneous T-cell lymphoma, other lymphoproliferative disorders, granuloma annulare, Langerhans cell histiocytosis, lichen planus, and localized scleroderma.1,2 The term excimer is derived from “excited dimer,” which describes the mixture of the noble gas xenon and the halogen chloride gas (XeCl) that is utilized. Overall, the 308 nm excimer laser is a very well tolerated treatment option for patients with psoriasis. Nonetheless, excimer lasers have been an effective therapy regardless of method utilized in various protocols. This demonstrated that the combination of excimer laser with alternating clobetasol spray and calcitriol ointment is a promising option and can easily be implemented in any treatment involving the excimer laser.30, In another 12-week study Levin et al treated moderate to severe psoriasis patients with twice weekly excimer treatments combined with twice daily clobetasol propionate followed by calcitriol ointment twice daily. The laser is particularly useful if these individuals have a suboptimal response or contraindications to topical or intralesional treatments. Objective: To prospectively evaluate the effect of the excimer laser on plaque psoriasis using an optimal therapeutic dose (OTD) protocol. Photodermatol Photoimmunol Photomed. 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. 2020 Jul;20(1):52-55. doi: 10.3892/etm.2020.8529.
