Ultraviolet-A1 phototherapy in Asian skin: A review of 159 cases in Singapore.

BACKGROUND: Ultraviolet-A1 phototherapy has been used to treat many inflammatory dermatoses. AIMS: To determine the efficacy and safety of ultraviolet-A1 phototherapy in Asian skin. MATERIALS AND METHODS: We performed a review of records of patients undergoing ultraviolet-A1 phototherapy at our dermatology unit in Singapore from January 2007 to January 2011. Their electronic medical records were reviewed and a standardized questionnaire was filled up for data collection and tabulation. Chi-square or Fisher's exact tests were used to compare the difference in response between various groups for each characteristic. P value of < 0.05 was considered statistically significant. RESULTS: Our study comprised of 159 patients, of which 103 were patients with hand and foot eczema, 21 with atopic dermatitis, 17 with scleroderma and the remaining with miscellaneous dermatoses. Of these patients, 47.6% of patients with hand and feet eczema had good response after 10 sessions, which increased to 75% after 20 sessions and to 84.6% after 30 sessions. After 10 sessions, 47.6% of patients with atopic dermatitis had good response, which increased to 66.7% after 20 sessions. After 30 sessions, all the three remaining patients with atopic dermatitis experienced good response. For patients with scleroderma, only 11.8 and 10% had good response after 10 and 20 sessions, respectively, which increased to 40% after 30 sessions. LIMITATIONS: Limitations of our study include its retrospective design and, consequently, the lack of standardized treatment protocol, as well as subjective assessment in terms of clinical improvement. CONCLUSIONS: Ultraviolet-A1 phototherapy appears to be efficacious for the treatment of hand and foot eczema as well as atopic dermatitis. However, in patients with scleroderma, the response was partial and needed a longer duration of treatment.

Trends in phototherapy utilization among Medicare beneficiaries in the United States, 2000 to 2015.

BACKGROUND: Phototherapy is a cost-effective treatment for many dermatoses, yet the emergence of alternative therapies such as biologics led many to think that phototherapy utilization was declining. OBJECTIVE: To characterize national, historical phototherapy utilization and costs among Medicare beneficiaries. METHODS: Longitudinal analysis of the Medicare Part B National Summary Data File from 2000 to 2015 for phototherapy billing codes. Geographic distribution of clinics and provider type obtained from the Medicare Provider Utilization and Payment Data for 2012 to 2015. RESULTS: The overall volume of phototherapy services billed to Medicare from 2000 to 2015 increased by 5% annually, from 334,670 to 692,093. Ultraviolet B therapy comprised 77% of phototherapy volume, utilization of psoralen plus ultraviolet A therapy declined by 9% annually, and excimer laser services grew by 29% annually. The number of phototherapy clinics is increasing but remains concentrated in only 11% of US counties. Between 2012 and 2015, dermatologists accounted for 92% of phototherapy volume. LIMITATIONS: Commercial payers and institutional claims (hospital-based physicians) are excluded. Clinical indications for phototherapy use are not reported in this database. CONCLUSION: Phototherapy utilization has grown, though the service mix has shifted toward ultraviolet B and laser excimer therapy and away from psoralen plus ultraviolet A therapy. Dermatologists manage most phototherapy. Uneven geographic distribution of phototherapy clinics limits access in nonurban areas, and further evaluation is needed to determine its impact on rural communities.

Epidemiological survey from 2009 to 2012 of psoriatic patients in Japanese Society for Psoriasis Research.

Since 1982, the Japanese Society for Psoriasis Research has conducted annual epidemiological surveys of patients with psoriasis. Kawada et al. have reported data for 1982-2001 and Takahashi et al. have reported data for 2002-2008. The present study evaluated 9290 psoriatic cases according to age and sex (2009-2012). The male : female ratio was 2.08:1 (6281 male patients [67.6%] to 3009 female patients [32.4%]). The most prevalent type was psoriasis vulgaris (85.6% of all cases), which was followed by psoriasis arthropathica (6.0%), psoriasis guttate acuta (3.2%), Zumbusch-type generalized pustular psoriasis (1.8%) and psoriasis erythroderma (1.5%). Psoriasis vulgaris was the most prevalent type for all ages, while psoriasis arthropathica and psoriasis guttate acuta were most prevalent among patients aged less than 65 years. The present survey detected an increased number of cases with comorbid diabetes and/or arthritis symptoms compared with the previous surveys. We found that treatments frequently involved topical corticosteroids (89.7% of cases) and vitamin D3 ointments (78.0% of cases), with a notable increase in the use of vitamin D3 ointments. Systemic treatments were used in 33.3% of cases, including cyclosporin (33.6%), etretinate (19.5%), methotrexate (8.6%), infliximab (11.4%), adalimumab (10.9%) and ustekinumab (6.2%). Phototherapy was used in 30.9% of cases. Although psoralen plus ultraviolet A therapy was the predominant phototherapy during previous studies, the present survey revealed that narrowband ultraviolet B therapy was used in 84.5% of phototherapy-treated cases. Thus, the present survey revealed major changes in treatment trends.

A Systematic Review of Light Emitting Diode (LED) Phototherapy for Treatment of Psoriasis: An Emerging Therapeutic Modality.

Background: Psoriasis is a chronic, inflammatory skin condition. The economic burden of psoriasis is approximately $35.2 billion in the United States per year, and treatment costs are increasing at a higher rate than general inflation. Light emitting diode (LED) phototherapy may represent a cost-effective, efficacious, safe, and portable treatment modality for psoriasis.

Objective: The goal of our manuscript is to review the published literature and provide evidence-based recommendations on LED phototherapy for the treatment of psoriasis.

Methods & Materials: A search of the databases Pubmed, EMBASE, Web of Science, and CINAHL was performed on April 5, 2016. Key search terms were related to psoriasis and LED-based therapies.

Results: A total of 7,793 articles were generated from the initial search and 5 original articles met inclusion criteria for our review. Grade of recommendation: B for LED-blue light. Grade of recommendation: C for LED-ultraviolet B, LED-red light, and combination LED-near-infrared and LED-red light.

Conclusion: We envision further characterizing the effects of LED phototherapy to treat psoriasis in patients may increase adoption of LED-based modalities and provide clinicians and patients with new therapeutic options that balance safety, efficacy, and cost.

Phototherapy for mycosis fungoides.

BACKGROUND: Both phototherapy and photochemotherapy have been used in all stages of mycosis fungoides since they improve the symptoms and have a favourable adverse effect profile. MATERIALS AND METHODS: We performed an extensive search of published literature using keywords like "phototherapy", "photochemotherapy", "NBUVB", "PUVA", "UVA1", "mycosis fungoides", and "Sezary syndrome", and included systematic reviews, meta-analysis, national guidelines, randomized controlled trials (RCTs), prospective open label studies, and retrospective case series. These were then arranged according to their levels of evidence. RESULTS: Five hundred and forty three studies were evaluated, of which 107 fulfilled the criteria for inclusion in the guidelines. CONCLUSIONS AND RECOMMENDATIONS: Photochemotherapy in the form of psoralens with ultraviolet A (PUVA) is a safe, effective, and well tolerated first line therapy for the management of early stage mycosis fungoides (MF), that is, stage IA, IB, and IIA (Level of evidence 1+, Grade of recommendation B). The evidence for phototherapy in the form of narrow-band UVB (NB-UVB) is less robust (Level of evidence 2++, Grade of recommendation B) but may be considered at least as effective as PUVA in the treatment of early-stage MF as an initial therapy. In patients with patches and thin plaques, NB-UVB should be preferentially used. PUVA may be reserved for patients with thick plaques and those who relapse after initial NB-UVB therapy. For inducing remission, three treatment sessions per week of PUVA phototherapy or three sessions per week of NB-UVB phototherapy may be advised till the patient achieves complete remission. In cases of relapse, patients may be started again on PUVA monotherapy or PUVA may be combined with adjuvants like methotrexate and interferon (Level of evidence 2+, Grade of recommendation B). Patients with early-stage MF show good response to combination treatments like PUVA with methotrexate, bexarotene or interferon-α-2b. However, whether these combinations hold a significant advantage over monotherapy is inconclusive. For late stage MF, the above-mentioned combination therapy may be used as first-line treatment (Level of evidence 3, Grade of recommendation C). Currently, there is no consensus regarding maintenance therapy with phototherapy once remission is achieved. Maintenance therapy should not be employed for PUVA routinely and may be reserved for patients who experience an early relapse after an initial course of phototherapy (Level of evidence 2+, Grade of recommendation B). Bath-water PUVA may be tried as an alternative to oral PUVA in case the latter cannot be administered as the former may show similar efficacy (Level of evidence 2-, Grade of recommendation C). In pediatric MF and in hypopigmented MF, both NB-UVB and PUVA may be tried (Level of evidence 3, Grade of recommendation D).

Trends in home phototherapy adoption in the US: monetary disincentives are only the tip of the iceberg.

There are often multiple hurdles that must be crossed to obtain home phototherapy devices. To identify these obstacles, we examined survey data from the National Biological Corporation on patients who never acquired a home unit after being given a prescription from their doctors. Additionally, physicians' prescribing patterns were assessed from data gathered by IMS Health. Physician education of and willingness to prescribe home phototherapy was assessed via a survey distributed at the 9th Annual Dermatology Chief Residents' Meeting. When psoriasis patients were written a prescription for home phototherapy, less than half acquired a unit. Most patients (72%) stated that they did not get a unit secondarily to the high out-of-pocket expenses. In 2006, dermatologists wrote 94,385 new scripts for etanercept, compared with only 1073 scripts for home phototherapy. Very few (35%) dermatology residents receive formal training on home phototherapy. When it comes to the reasons behind patients receiving significantly more expensive biologics instead of home phototherapy for their psoriasis, high copays and deductibles are just the tip of the iceberg. It is likely that even more patients are never prescribed a home unit due to lack of physician training or frustration with meager and often inadequate reimbursements from insurance.

Collagen cross-linking: a new treatment paradigm in corneal disease - a review.

The last 2 years has seen a marked increase in the prominence of corneal collagen cross-linking as a treatment strategy for progressive keratoconus. This interest has arisen from a body of laboratory evidence documenting the biomechanical and cellular changes induced by cross-linking. The findings of this research provide a plausible rationale for its use in keratoconus to retard the progression of this common disease. The rapidly growing number of clinical reports suggests, not only a consistent stabilizing effect of cross-linking, but that a variable improvement in corneal shape and visual function may also occur in some patients. However, the marked variation in the clinical course of keratoconus, together with the challenges of accurately evaluating refractive error, visual acuity and even corneal shape in this condition, demands further evidence from randomized controlled clinical trials. The aim of this review is to summarize the theoretical basis and risks of corneal collagen cross-linking, along with the available evidence for its use in keratoconus and other corneal disease states.

[New and rarley used treatment options for refractory hand eczema: local UVA-1 phototherapy, retinoids, calcineurin inhibitors]. / Neue und seltener angewandte Therapieoptionen bei therapierefraktärem Handekzem: Lokale UVA-1-Phototherapie, Retinoide, Calcineurininhibitoren.

Hand eczema (HE) is one of the most frequent skin diseases. HE has a wide spectrum, with variable etiology, severity, and morphology. It often displays a chronically relapsing course with a poor prognosis, and has a high impact on the quality of life. Although different treatment options exist, the management of patients with chronic HE is often unsatisfactory. We highlight new and rarely used approaches to treat chronic HE uncluding local UVA-1-phototherapy, retinoids including the new oral retinoid alitretinoin, and calcineurin inhibitors.

Vitiligo: new and emerging treatments.

Vitiligo is a cosmetically disfiguring condition, and, although there is no therapeutic full solution yet, some treatment may induce good results in most patients. The disease can be successfully treated with various medical options. Both nonfocused or focused narrowband ultraviolet B phototherapy represents the current treatment of choice, to minimize side effects and reach optimal clinical results. Topical novel approaches are also considered. Surgical methods, consisting of autologous transplantation methods, is generally recommended for focal/stable vitiligo, after medical therapy has failed. Finally, for patients with extensive vitiligo, depigmentation of the residual melanin should be taken into account.

Narrowband UVB phototherapy for the treatment of psoriasis: a review and update.

An advance in UVB-based phototherapy has been the introduction of fluorescent lightbulbs (Philips TL-01) that deliver monochromatic light at 311-nm UVB, a narrowband wavelength that seems to maximize clearing of plaques relative to its erythrogenic potential. Narrowband UVB phototherapy has considerable advantages over traditional treatment options such as broadband UVB and psoralen plus UVA (PUVA). It is clearly more effective than broadband UVB, safer than PUVA, and well tolerated by patients when taken at suberythemogenic doses. Narrowband UVB represents an important new therapy for psoriasis.

Phototherapy and photochemotherapy: an update.

Three types of phototherapy and 2 forms of photochemotherapy are now available for treatment of more than 40 diseases of the skin. Broadband ultraviolet B (UVB) phototherapy and oral psoralen photochemotherapy (PUVA) therapy are most widely available while there has been increased interest in topical PUVA therapy. Narrow-band UVB phototherapy and UVA-1 phototherapy offer potential for the future.
