[Pelotherapy and pelotherapy combined with intravenous laser blood irradiation at the sanatorium-resort stage of treatment of patients with psoriasis vulgaris]. / Peloidoterapiya i peloidoterapiya v sochetanii s vnutrivennym lazernym osvechivaniem krovi na sanatorno-kurortnom etape lecheniya bol'nykh vul'garnym psoriazom.

Search of new rational ways to increase the effectiveness of treatment and rehabilitation measures for patients with psoriasis vulgaris continues to be one of the urgent problems in modern clinical dermatology. OBJECTIVE: To carry out a comparative analysis of the impact of different variants of sanatorium-resort treatment (SRT) - pelotherapy and pelotherapy in combination with intravenous laser blood irradiation (ILBI) - on the level of IL-17 and TNF-a, dermatological status, psychoemotional state and quality of life (QL) assessment of patients with psoriasis vulgaris. MATERIAL AND METHODS: A naturalistic comparative study included 120 patients with psoriasis vulgaris, who were undergoing SRT: 57 patients in the pelotherapy group and 63 in the group of pelotherapy in combination with ILBI. The SRT effectiveness was assessed using the PASI index, the HARS and HDRS scales and the DLQI questionnaire. The dynamics of IL-17 and TNF-a plasma levels in blood plasma was studied. The study duration was 6 months 14 days. RESULTS: After 14 days of SRT, a decrease in IL-17 and TNF-a levels in blood plasma was statistically significant both in the pelotherapy group and in the group of pelotherapy in combination with ILBI, no statistically significant differences between the groups were found. Furthermore, the comprehensive use of pelotherapy in combination with ILBI has contributed to a more pronounced statistically significant decrease in the PASI index, the HARS and HDRS scales' total scores and an increase in the level of QL. The number of patients with clinical remission was statistically higher in the group of pelotherapy combined with ILBI compared to the pelotherapy group (87.3% versus 42.1%) six months after SRT. CONCLUSION: The advantage of comprehensive application of pelotherapy and ILBI in comparison with pelotherapy in patients with psoriasis vulgaris in SRT has been shown. The comprehensive application of pelotherapy and ILBI reduces the level of inflammatory biomarkers, improves dermatological and psychoemotional status, improves QL and is well tolerated by patients.

TWEAK levels in psoriatic patients treated with narrowband ultraviolet B and methotrexate.

BACKGROUND: Psoriasis is an autoimmune disease which has an effect on the joints and skin. Tumor Necrosis Factor-Like Weak Inducer of Apoptosis (TWEAK) is a multi-functional cytokine which regulates the cellular processes and has been related to a variation of conditions. OBJECTIVES: To measure the level of serum TWEAK in psoriatic diseased persons and its relationship to the PASI score pre- and post-therapy with narrowband ultraviolet B phototherapy (NB-UVB) and methotrexate (MTX). METHODS: This randomized controlled trial was conducted on 40 patients and 20 healthy persons as controls. Patient Group was randomly subdivided to two groups. The 1st group consisted of 20 patients who received NB-UVB treatment. The 2nd group included 20 MTX-treated candidates. Blood samples were drawn from patients in order to detect serum TWEAK levels using ELISA. The research was registered on Clinical Trials Registration: RCT approval numbers: NCT0481191. RESULTS: The mean PASI score percent improvement after 12 weeks of treatment was higher in the MTX group (90%) than NB-UVB group (60%). The serum TWEAK level at baseline was 60.47 ± 12.6 pg/mL in NB-UVB group and 54.69 ± 21.7 pg/mL in MTX group which reduced to 24.93 ± 17.6 pg/mL and 32.13 ± 23.6 pg/mL, respectively (p < 0.001), after 12 weeks of treatment. There was a positive correlation between the serum levels of TWEAK and severity of PASI score (r = 0.399, p = 0.014). CONCLUSION: TWEAK grades in psoriasis are substantially higher than in controls. TWEAK levels were dramatically reduced during NB-UVB and MTX treatment. TWEAK may have a potential sign for psoriasis diagnosis and prognosis.

Multiple Bowen's disease due to long-term narrow-band ultraviolet B phototherapy: A case report and literature review.

OBJECTIVE: By presenting a case study on multiple instances of Bowen's disease and the consistent use of narrow-band ultraviolet B (NB-UVB) phototherapy over a three-year period, our aim is to enhance the comprehension of domestic clinicians regarding the disease. Additionally, we seek to review existing literature, encouraging dermatologists to consider clinical secondary primary lesion diagnoses. METHOD: Our approach involves analyzing a diagnosed case of multiple Bowen's disease, examining clinical manifestations, histopathology, imaging results, and treatment methods related to NB-UVB phototherapy. We aim to facilitate discussion and understanding through a comprehensive literature analysis. RESULTS: An elderly male with a 30-year history of psoriasis vulgaris initiated continuous NB-UVB therapy three years ago. A year later, he developed red patches and plaques with distinct borders and scaly surfaces on his face, trunk, lower extremities, and scrotum. Histopathological examination confirmed Bowen's disease. Treatment involved liquid nitrogen cryotherapy, with no recurrence observed during the one-year follow-up. CONCLUSION: This case highlights that Bowen's disease, typically solitary, can manifest as multiple instances, especially in individuals with a history of psoriasis vulgaris. While NB-UVB stands as the primary treatment for psoriasis vulgaris, caution is warranted due to the potential risk of skin tumor induction with prolonged high-dose usage. Clinicians should be vigilant in monitoring and assessing the long-term implications of such therapies.

A focused review on laser- and energy-assisted drug delivery for nail disorders.

The purpose of this review is to consolidate and summarize laser-assisted drug delivery (LADD) for nail diseases, particularly onychomycosis and psoriasis. A PubMed search was conducted in June 2023 using search terms (1) "laser assisted drug delivery" AND "nail," (2) "laser" AND "nail," and (3) "nail disorder" AND "laser treatment." References of papers were also reviewed, yielding 15 papers for this review. Fractional ablative CO2 laser (FACL) and Er:YAG laser can be used for LADD of topical medications such as amorolfine, terbinafine, and tioconazole to treat onychomycosis. A fungal culture should be performed to determine the type of dermatophyte, which will help determine which topical will be most effective. Laser settings varied between studies, but overall LADD tended to be more effective than topical treatments alone. Laser-assisted photodynamic therapy (PDT) was also found to be effective in treating onychomycosis. For psoriatic nails, LADD was used to deliver calcipotriol-betamethasone dipropionate foam, tazarotene, triamcinolone, or methotrexate into the nail. Again, LADD was found to be significantly more effective than topical treatment alone. FACL was the only laser noted for use for LADD in both diseases. Laser-assisted drug delivery for nail disease is a newer approach for onychomycosis and nail psoriasis with several benefits and drawbacks. Dermatologists should discuss the option of LADD with their patients who have recalcitrant onychomycosis or nail psoriasis.

Excimer light effect on neurogenic inflammation in active versus stable psoriasis lesions.

Neurogenic inflammation, mediated by T helper 17 cell (Th17) and neurons that release neuropeptides such as substance P (SP), is thought to play a role in the pathogenesis of psoriasis. Excimer light is used in the treatment of psoriasis via induction of T cell apoptosis. The objective of this study is to study the effect of excimer light on active versus stable psoriasis and investigate the levels of substance P and its receptor in both groups. The study included 27 stable and 27 active psoriatic patients as well as 10 matched healthy controls. Clinical examination (in the form of local psoriasis severity index (PSI) and visual analogue scale (VAS)) was done to determine disease severity, level of itching, and quality of life. Tissue levels of SP and neurokinin-1 receptor (NK-1R) were measured by ELISA before and after 9 excimer light sessions in 43 patients. A statistically significant lower levels of PSI and VAS were reached after therapy with no significant difference between the stable and active groups. The mean tissue levels of SP before therapy were significantly higher than the control group. Lower levels of SP and NK-1 receptor were found after treatment overall and in each group. Excimer therapy can be effective for both stable and active plaque psoriasis and this effect could be partly through its role on ameliorating the neurogenic inflammation.

Frequency of skin cancer among psoriasis, vitiligo, and mycosis fungoides patients treated with narrowband ultraviolet B phototherapy.

BACKGROUND: Narrowband ultraviolet B (NB-UVB) phototherapy is a popular and relatively contemporary treatment option. However, only a few studies to date have explored the potential risk of skin cancer following NB-UVB treatment. OBJECTIVE: This study aimed to investigate the potential long-term risk of skin cancer in patients treated with NB-UVB. METHODS: This cohort study included patients with psoriasis, vitiligo, and mycosis fungoides treated with NB-UVB at two university hospitals in Israel in 2000-2005. Patients were followed up for skin cancer for at least 10 years. Data were extracted from the hospital and community medical records. RESULTS: A total of 767 patients were included in this study: 509 with psoriasis, 122 with vitiligo, and 136 with mycosis fungoides. The mean follow-up duration was 13 years. Among these patients, 4.43% developed skin cancer during the follow-up (3.93% had psoriasis, 2.46% had vitiligo, and 8.09% had mycosis fungoides). Old age and fair skin type were the only significant independent risk factors for skin cancer. There was no significant difference in the mean number of NB-UVB treatments among patients who developed skin cancer and those who did not (99.09 vs. 94.79, respectively). CONCLUSION: No association was observed between the number of NB-UVB treatments and carcinogenesis in any study group. Age is a significant risk factor, and older patients treated with NB-UVB should be followed up carefully.

Current practices for pediatric phototherapy: Findings from a cross-sectional study.

Phototherapy is broadly utilized for treatment of inflammatory skin conditions affecting pediatric patients. However, there are no specific guidelines or recommendations for implementing phototherapy in pediatric populations leading to variability in treatment procedures. Here, we present findings from a cross-sectional, survey-based study investigating the implementation of phototherapy in pediatric patients across the United States. A total of 39 sites from 19 different states identified via the National Psoriasis Foundation (NPF) Health Care Provider Directory responded. Common practices included a signed informed consent prior to performing phototherapy (86.4%, n = 32), no minimum age requirement for pediatric patients (91.8%, n = 34), the use of Fitzpatrick skin type to determine dosing protocol (100%, n = 37), and allowing parents to accompany their children into the lightbox (65%, n = 20). Our results provide insights into current common practices and themes for further study.

Could red and near-infrared emitting fabric technology improve the severity of psoriasis, polymorphous light eruption, and alopecia areata?

AIM: Low-level light therapy (LLLT) may offer an adjunctive therapeutic tool for inflammatory skin conditions. This pilot study assessed the efficacy of a red/near-infrared (NIR)-emitting fabric for psoriasis, polymorphous light eruption (PMLE), and alopecia areata (AA). METHODS: Fourteen patients (five with psoriasis, five with PMLE, and four with AA) were instructed to wear a red/NIR-emitting (Lumiton®) garment during the 12-week study. Efficacy was assessed subjectively by patient-reported improvement and objectively by the redness, thickness, and scale of elbow psoriasis plaques, the frequency of PMLE flares, and the Severity of Alopecia Tool (SALT) score. RESULTS: Three patients with psoriasis completed the study while two self-discontinued. The three patients who completed the study noted improvement and two had improvements in lesion redness, thickness, or scale, while one was clinically stable. Three patients with PMLE completed the study, and none had a disease flare during the study period. Three patients with AA completed the study: two reported disease improvement and all three had an improved SALT score. CONCLUSION: Use of a wellness apparel that emits red and NIR light may be associated with improved disease severity in patients with mild elbow psoriasis, PMLE, and limited AA. Limitations of this study include continuation on topical, intralesional, or systemic medications and small sample size.

This cohort study describes and identifies patient characteristics associated with use of in-office narrowband UV-B (NBUVB) or systemic therapy following home NBUVB machine receipt.

The Effect of Narrow-Band Ultraviolet B Phototherapy on Free and Total Vitamin D Serum Levels in Mild to Severe Plaque Psoriasis.

Vitamin D plays an important role in skin inflammation in psoriasis. The beneficial effects of ultraviolet light B (UVB) phototherapy in psoriasis are partly attributed to UVB-induced increase of vitamin D levels. In clinical practice, total 25-hydroxy vitamin D (25(OH)D) levels are measured to assess sufficiency, but it might be more accurate to measure free 25(OH)D levels. The aim of this study was to measure free serum 25(OH)D levels in psoriasis patients before and after phototherapy and to investigate if free 25(OH)D correlates stronger to disease severity than total 25(OH)D. Twenty adults (>18 years) with psoriasis were included for treatment with narrow-band UVB (NB-UVB) phototherapy for 10-12 weeks. Psoriasis Area and Severity Index (PASI) and Visual Analogue Scale (VAS) were used to assess disease severity. Serum levels of total 25(OH)D, free 25(OH)D, and 1,25(OH)2D were measured before and after NB-UVB. Total 25(OH)D, free 25(OH)D, 1,25(OH)2D and the percentage of free 25(OH)D increased after NB-UVB, and PASI and VAS improved. The increase in total and free 25(OH)D remained significant when stratifying for vitamin D confounders. No correlations between disease severity and vitamin D levels were found. Total and free 25(OH)D levels were positively correlated before and after NB-UVB. NB-UVB is an effective treatment for mild to severe plaque psoriasis and increases not only total but also free 25(OH)D levels, as well as the percentage of free 25(OH)D, suggesting an increased bioavailability of skin-produced vitamin D.

Noninvasive treatment of psoriasis and skin rejuvenation using an akermanite-type narrowband emitting phosphor.

Psoriasis is a noncontagious, long-lasting skin infection that affects many people around the world. Numerous therapeutic artificial treatments are available for the treatment of psoriasis, such as photodynamic therapy using broadband ultraviolet (UV) lamps, which have harmful effects on human skin. Similarly, the natural healing systems such as sunlight have a higher risk of sunburn and can cause dangerous forms of skin cancer. Significant light emission of a specific wavelength (in the UV range), and phosphor-based devices demonstrate the effectiveness of treating psoriasis without damaging the skin. Gd3+ -doped calcium magnesium silicate [Ca2 MgSi2 O7 :Gd3+ ,(CMS:Gd3+ )] phosphor is one of the ideal phosphors that emit specific narrow UV wavelengths for curing psoriasis and is in great demand in the field of dermatology. Photoluminescence analysis at room temperature (~25°C) shows that the synthesized CMS:Gd3+ phosphor emits narrowband UV-B light with a peak intensity at 314 nm. Comparative studies of the standard action spectrum of psoriasis with the emission spectrum of the CMS:Gd3+ phosphor show that the synthesized phosphor was the most suitable material for treating a variety of diseases, including psoriasis, vitiligo, type-1 diabetes, dental disease, sleep and mood disorders, and other skin diseases.

Comparative evaluation of efficacy and safety of calcipotriol versus calcitriol ointment, both in combination with narrow-band ultraviolet B phototherapy in the treatment of stable plaque psoriasis.

BACKGROUND: Vitamin D analogues and NBUVB are both well-recognised modes of therapy in the treatment of chronic stable plaque psoriasis. The objective of this open label intraindividual, left right study was to compare two different vitamin D analogues, calcipotriol and calcitriol, in combination with NBUVB phototherapy in psoriasis. METHODS: Thirty patients with stable plaque psoriasis were enrolled for a 12-week clinical trial. The target lesion on the left side was treated topically with calcitriol ointment, while that on the right side was treated with calcipotriol ointment once daily. The whole body was irradiated with narrow-band ultraviolet B phototherapy (NBUVB) three times per week. Efficacy was assessed by target plaque scoring. RESULTS: Both therapies resulted in a statistically significant reduction in erythema, scaling, thickness, and target plaque score, seen as early as 2 weeks into therapy. However, the calcipotriol combination led to an earlier clearance of plaques and a lesser relapse rate than the calcitriol combination. The number of treatment sessions and cumulative NBUVB doses were significantly lower in the calcipotriol-treated group. CONCLUSION: Both vitamin D analogues appear to be safe, effective, and cosmetically acceptable, with calcipotriol being more efficacious, well tolerated, with a rapid onset of action and a better maintenance of response.

Systematic review and estimated cost-efficacy of biologics compared with narrowband ultraviolet B light for the treatment of moderate to severe psoriasis and atopic dermatitis.

Psoriasis and atopic dermatitis are chronic inflammatory skin conditions, each affecting about 2-3% of the United States adult population. Phototherapy, such as narrowband ultraviolet-B (NB-UVB) therapy have been employed for the treatment of both psoriasis and atopic dermatitis for decades. More recently, systemic biologics have been approved by the Food and Drug Administration (FDA), representing a great advancement in dermatology. No comprehensive study to date has compared the cost efficacy of phototherapy compared to FDA-approved biologics for the treatment of psoriasis and atopic dermatitis. We pursued a systematic review of the literature for studies assessing efficacy of NB-UVB or biologics with endpoints including the Psoriasis Area and Severity Index (PASI) and the Eczema Area and Severity Index (EASI). Thirty-four studies including 55 treatment regimens and 5,123 patients were included in the analysis. Phototherapy costs were estimated with Medicare fee schedules for phototherapy-related current procedural terminology code (CPT), and biologic costs were estimated with wholesale acquisition cost (WAC). Total costs to achieve PASI 75 or EASI 75 in each study were standardized to a single month, the "adjusted cost," and exploited to a year, the "effective yearly cost," allowing direct cost-efficacy comparison despite different durations of treatment described in studies. The psoriasis analysis found NB-UVB to be the most cost-effective therapy, with an adjusted monthly cost of $1714.00 per PASI 75. Infliximab was the least expensive biologic, with an adjusted monthly cost of $2076.00 to $2502.00 per PASI 75. For atopic dermatitis, no NB-UVB studies utilized EASI 75 as their outcome measure, hindering the ability to directly compare cost effectiveness for the treatment of atopic dermatitis. However, all NB-UVB studies depicted a reduced treatment cost per treatment period compared to studies assessing biologics, although this comparison does not account for efficacy. The results depict NB-UVB to be the most cost effective for the treatment of psoriasis and the least expensive per treatment period for the treatment of atopic dermatitis. However, certain factors need to be taken into account. Biologics may be more effective for more severe disease, do not require multiple weekly clinic visits, and the ease for patient compliance may lead some to favor biologic therapy. This study is necessary to allow physicians, patients, and health systems to make informed decisions regarding cost-efficacy for a variety of treatment options.

Elucidating the NB-UVB mechanism by comparing transcriptome alteration on the edge and center of psoriatic plaques.

Narrow band-ultraviolet B (NB-UVB) is an effective treatment for psoriasis. We aim to generate a potential mechanism of NB-UVB through comparing the transcriptomic profile before and after NB-UVB treatment between the peripheral edge of lesional skin (PE skin) and the center of lesional skin (CE skin) on the basis of molecular mechanisms of these two areas display different downstream functions. More than one-fourth of the NB-UVB-altered genes were found to be plaque-specific. Some of them were psoriasis signature genes that were downregulated by NB-UVB in, both, PE and CE skin (core alteration), such as IL36G, DEFB4A/B, S100A15, KRT16, and KRT6A. After NB-UVB treatment, the activity score of upstream cytokines, such as interferons, interleukin (IL)-6, IL-17, and IL-22 in pathogenesis decreased. In addition, NB-UVB could restore normal keratinization by upregulating LORICRIN and KRT2, particularly in the CE skin. Finally, we illustrated that NB-UVB is capable of suppressing molecules from the initiation to maintenance phase of plaque formation, thereby normalizing psoriatic plaques. This finding supports the usefulness of NB-UVB treatment in clinical practice and may help in the development of new treatment approaches in which NB-UVB treatment is included for patients with psoriasis or other inflammatory skin diseases.

Secukinumab demonstrates superiority over narrow-band ultraviolet B phototherapy in new-onset moderate to severe plaque psoriasis patients: Week 52 results from the STEPIn study.

BACKGROUND: Biologic treatments have been studied mainly in patients with a long-term history of psoriasis and previous treatment failures. OBJECTIVES: The purpose of this primary analysis of the STEPIn study is to determine whether early intervention with secukinumab in patients with new-onset moderate to severe plaque psoriasis is superior to standard of care treatment with narrow band ultraviolet B (nb-UVB) phototherapy. METHODS: The STEPIn study is a randomized, open-label, multicentre study to investigate early intervention with 52 weeks of secukinumab 300 mg administered subcutaneously versus standard treatment with nb-UVB phototherapy in patients with new-onset (≤12 months) moderate to severe plaque psoriasis (NCT03020199). The primary and additional secondary endpoints were ≥90% improvement in Psoriasis Area and Severity Index (PASI 90) at Week 52 and Investigator's Global Assessment (IGA mod 2011) 0/1 response at Week 52, respectively. RESULTS: In the secukinumab and nb-UVB study arms, 77/80 and 76/80 randomized patients received at least one dose of study treatment, respectively. The primary endpoint was achieved: 91.1% (70/77) of patients achieved a PASI 90 response at Week 52 in the secukinumab arm versus 42.3% (32/76) in the nb-UVB arm (p < 0.0001, odds ratio [OR] estimate [95% confidence intervals, CI] = 16.3 [5.6, 46.9]). The additional secondary endpoint was also achieved: 85.7% of patients achieved an IGA 0/1 response at Week 52 in the secukinumab arm versus 36.8% in the nb-UVB arm (p < 0.0001). The safety data were consistent with the safety profiles of secukinumab and nb-UVB with no new or unexpected safety signals. CONCLUSIONS: Secukinumab was superior to nb-UVB in treating patients with new-onset moderate to severe plaque psoriasis. The high and sustained skin clearance observed indicates that biologic treatment for psoriasis may be more effective if used early in the disease course.

Opportunities for implementing a patient-initiated follow-up pathway for patients with psoriasis completing phototherapy.

We performed a retrospective case analysis to identify opportunities to introduce a patient-initiated follow-up (PIFU) pathway for patients with psoriasis completing narrowband ultraviolet B phototherapy at our centre. In total, 42 patients completed phototherapy between January 2016 and August 2018 and outcomes were observed for 36 months after phototherapy cessation. Had a PIFU pathway been in place, 24 routine follow-up appointments could have been saved and 8 nonattendances could have been avoided. Seven patients who were discharged or did not attend follow-up after phototherapy flared within 12 months and could have benefited from PIFU to re-access dermatology care. In total 21 patients (50.0%) experienced a relapse within 36 months of completion of phototherapy, and 18 of these (85.7%) relapsed at 0-12 months. The median time to relapse was 6 months. We conclude a post-phototherapy PIFU pathway could help eliminate unnecessary appointments for patients in remission and improve access for patients who relapse. A 12-month PIFU duration prior to discharge would be sufficient to capture the majority of relapses.

Impact of NB-UVB phototherapy on Caveolin-1 expression in chronic plaque psoriasis.

BACKGROUND: Caveolin-1 (Cav-1) is a significant structural and regulatory constituent of cell membranes that has been implicated in cell kinetics and inflammation. OBJECTIVE: To assess Cav-1 expression in psoriasis before and after phototherapy. PATIENTS AND METHODS: Thirty psoriasis cases and 30 healthy controls were recruited. Cases were managed with narrow band-ultraviolet B (NB-UVB) phototherapy at frequency three times per week for 12 weeks. From every case, two biopsy specimens were gained from psoriatic lesions (pre and post phototherapy), in addition to one from apparently normal skin of psoriasis cases. Regarding the control group, one biopsy was taken from a matched site. All were studied for Cav-1 antibody immuno-expression. RESULTS: There was a significant decrease in Cav-1 expression in psoriatic lesions compared to both the apparently normal skin of psoriasis patients and standard control skin of healthy individuals. After NB-UVB phototherapy, significant upregulation of Cav-1 immunostaining score was observed in previously psoriatic skin when compared to that before treatment. In addition, there were significant negative correlations between Cav-1 immunostaining score and the clinical scores of psoriasis severity including; the erythema, scaling, and induration (ESI) score and the patient psoriasis area and severity index (PASI) score. CONCLUSION: Induction of Cav-1 expression may be a likely pathway for the effectiveness of NB-UVB in psoriasis. Cav-1 may be a useful marker for evaluation of psoriasis severity, disease progression, and therapeutic efficacy.
