Efficacy of optometric phototherapy: a systematic review

PURPOSE

To analyse the scientific evidence about the efficacy of Syntonic phototherapy for producing changes in visual function.

MATERIAL AND METHODS

A systematic review was performed to obtain studies on the effects of Syntonic phototherapy on vision. A search in health science databases (Medline, Scopus, Web of Science and PsycINFO) for studies published between 1980 and 2022 was conducted in accordance with the principles of Cochrane approach. The search identified 197 articles. Only clinical studies which used the Syntonic phototherapy as a vision therapy for any visual condition were included. Clinical cases and case series were excluded. Following the inclusion criteria, 8 clinical studies met inclusion, 5 of them being pseudo-experimental studies with an equivalent control group and 3 pre-post pseudo-experimental studies. GRADE tool was used to assess the certainty of the evidence of the studies. The GRADE evidence profile for the studies through the Soft table was made to analyse data.

RESULTS

The studies analysed seven outcomes: visual symptoms, functional visual fields, visual acuity, contrast sensitivity, deviation (phoria/tropia), stereopsis and reading abilities. Finding table about results (Soft Table) showed that for all outcomes reviewed, all studies yielded very low certainty of evidence. Results revealed a lack of scientific evidence of the efficacy of Syntonic optometric phototherapy to produce changes in the visual function.

CONCLUSION

This systematic review found no consistent evidence for the efficacy of Syntonic phototherapy to cause changes in visual function. There is no scientific evidence to support its clinical use for treating any type of visual anomalies.

Impact of low-dose calcipotriol ointment on wound healing, pruritus and pain in patients with dystrophic epidermolysis bullosa: A randomized, double-blind, placebo-controlled trial

Background

Wound management is a critical factor when treating patients with the inherited skin fragility disease dystrophic epidermolysis bullosa (DEB). Due to genetic defects in structural proteins, skin and mucous epithelia are prone to blistering and chronic wounding upon minor trauma. Furthermore, these wounds are commonly associated with excessive pruritus and predispose to the development of life-threatening squamous cell carcinomas, underscoring the unmet need for new therapeutic options to improve wound healing in this patient cohort. Vitamin D3 is acknowledged to play an important role in wound healing by modulating different cellular processes that impact epidermal homeostasis and immune responses. In this study, we evaluate the safety and efficacy of low-dose calcipotriol, a vitamin D3 analogue, in promoting wound healing and reducing itch and pain in patients with DEB.

Methods

Eligible DEB patients, aged ≥ 6 years and with a known mutation in the COL7A1 gene, were recruited to a placebo-controlled, randomized, double blind, cross-over phase II monocentric clinical trial. Patients were required to have at least two wounds with a minimum size of 6 cm² per wound. The primary objective was to evaluate efficacy of daily topical application of a 0.05 µg/g calcipotriol ointment in reducing wound size within a 4-week treatment regimen. Secondary objectives were to assess safety, as well as the impact of treatment on pruritus, pain, and bacterial wound colonization in these patients.

Results

Six patients completed the clinical trial and were included into the final analysis. Topical low-dose calcipotriol treatment led to a significant reduction in wound area at day 14 compared to placebo (88.4% vs. 65.5%, P < 0.05). Patients also reported a significant reduction of pruritus with calcipotriol ointment compared to placebo over the entire course of the treatment as shown by itch scores of 3.16 vs 4.83 (P < 0.05) and 1.83 vs 5.52 (P < 0.0001) at days 14 and 28, respectively. Treatment with low-dose calcipotriol did not affect serum calcium levels and improved the species richness of the wound microbiome, albeit with no statistical significance.

Conclusions

Our results show that topical treatment with low-dose calcipotriol can accelerate wound closure and significantly reduces itch, and can be considered a safe and readily-available option to improve local wound care in DEB patients.

Systematic literature review of long-term efficacy data for topical psoriasis treatments

OBJECTIVE

To identify long-term efficacy evidence that supports use of topical therapies as regular maintenance therapy in the prevention of psoriasis relapse.

METHODS

A systematic literature review identified clinical trials and observational studies that reported efficacy outcomes for topical psoriasis therapies with treatment durations of at least 12 weeks. For therapies with long-term data, the approved treatment schedules in product labels were reviewed.

RESULTS

Forty-six studies with at least 12-week efficacy outcomes were identified. Eight randomized controlled trials and six observational studies or single-arm open-label studies reported efficacy data for >12-week treatment periods. Most studies used treatment regimens that reflect current standard of care of repeated treatment of relapses. The PSO-LONG study is the only identified randomized controlled trial to have compared regular proactive maintenance use of a topical treatment (calcipotriol/betamethasone foam) with reactive management in response to psoriasis relapses.

CONCLUSIONS

Limited high-quality long-term efficacy data are available for topical psoriasis therapies. While some product labels mention clinical experience of up to 12 months, they do not provide specific recommendations on the optimal long-term regimen. Calcipotriol/betamethasone foam is the only treatment for which the approved label allows either reactive treatment of relapse or regular (twice weekly) maintenance use.

Oral and Topical Vitamin D, Sunshine, and UVB Phototherapy Safely Control Psoriasis in Patients with Normal Pretreatment Serum 25-Hydroxyvitamin D Concentrations: A Literature Review and Discussion of Health Implications

Vitamin D, sunshine and UVB phototherapy were first reported in the early 1900s to control psoriasis, cure rickets and cure tuberculosis (TB). Vitamin D also controlled asthma and rheumatoid arthritis with intakes ranging from 60,000 to 600,000 International Units (IU)/day. In the 1980s, interest in treating psoriasis with vitamin D rekindled. Since 1985 four different oral forms of vitamin D (D2, D3, 1-hydroxyvitaminD3 (1(OH)D3) and 1,25-dihydroxyvitaminD3 (calcitriol)) and several topical formulations have been reported safe and effective treatments for psoriasis-as has UVB phototherapy and sunshine. In this review we show that many pre-treatment serum 25(OH)D concentrations fall within the current range of normal, while many post-treatment concentrations fall outside the upper limit of this normal (100 ng/mL). Yet, psoriasis patients showed significant clinical improvement without complications using these treatments. Current estimates of vitamin D sufficiency appear to underestimate serum 25(OH)D concentrations required for optimal health in psoriasis patients, while concentrations associated with adverse events appear to be much higher than current estimates of safe serum 25(OH)D concentrations. Based on these observations, the therapeutic index for vitamin D needs to be reexamined in the treatment of psoriasis and other diseases strongly linked to vitamin D deficiency, including COVID-19 infections, which may also improve safely with sufficient vitamin D intake or UVB exposure.

Combination of targeted UVB phototherapy and calcipotriene versus targeted UVB alone in psoriasis: systematic review and meta-analysis of randomized controlled trials

Background: Targeted UVB and topical calcipotriene have frequently been used in the treatment of psoriasis, but the joint effect of calcipotriene and targeted UVB has been controversial.Objectives: The purpose of this study was to systematically evaluate whether the efficacy of the combined use of targeted UVB and calcipotriene is superior to the targeted UVB alone.Methods: We performed systematic review and meta-analysis of randomized controlled trials (RCTs) in patients with plaque-type psoriasis through searching the defined key words in the PubMed, EMBase, and Cochrane Central Register databases. Pooled mean difference of the Psoriasis Area and Severity Index (PASI) relative change (%) was estimated using a random effect model. The quality of included studies and publication bias were assessed using the Jadad scale and the Egger's test, respectively.Results: A total of five RCTs including 182 patients were included in the systematic review. The mean difference of the PASI relative change (%) between the combined therapy versus the targeted UVB alone was -22.68 (95%CI: -37.12 to -8.24; p = .002). Publication bias was not supported by the Egger's test (p = .424).Conclusion: Addition of calcipotriene ointment may improve the efficacy of the targeted UVB phototherapy in the treatment of plaque-type psoriasis.

Safety considerations with combination therapies for psoriasis

Introduction: Psoriasis is a chronic inflammatory skin disease that waxes and wanes, and long-term remission can be difficult to achieve regardless of disease severity. Currently, numerous treatment options are available for psoriasis including steroid and non-steroid topical agents, phototherapy, oral systemic agents, and biologics, with many more therapeutic agents under development.Areas covered: This article will review various combination therapy strategies such as rotational therapy and sequential therapy and describe a variety of safe and effective combination therapies for the treatment of psoriasis. Two or more agents with different mechanisms of action and safety profiles can be used to achieve and/or maintain adequate disease control while minimizing the toxicity of treatments. Combination therapy can also be used when a single agent is not enough for treating recalcitrant disease. Choosing a combination regimen that maximizes safety and efficacy while considering patient usability and compliance can be a challenge.Expert opinion: Given the various treatment options currently available for psoriasis and more agents under development, combination therapy will continue to be a valuable treatment strategy for any patient with psoriasis. It is crucial for clinicians to carefully consider the fine balance between safety and efficacy when combining various therapeutic agents.

Diagnostic and therapeutic guidelines for plaque psoriasis - Brazilian Society of Dermatology

Psoriasis is a chronic inflammatory disease that affects 1.3% of the Brazilian population. The most common clinical manifestations are erythematous, scaling lesions that affect both genders and can occur on any anatomical site, preferentially involving the knees, elbows, scalp and genitals. Besides the impact on the quality of life, the systemic nature of the disease makes psoriasis an independent risk factor for cardiovascular disease, especially in young patients with severe disease. By an initiative of the Brazilian Society of Dermatology, dermatologists with renowned clinical experience in the management of psoriasis were invited to form a work group that, in a partnership with the Brazilian Medical Association, dedicated themselves to create the Plaque Psoriasis Diagnostic and Treatment Guidelines. The relevant issues for the diagnosis (evaluation of severity and comorbidities) and treatment of plaque psoriasis were defined. The issues generated a search strategy in the Medline-PubMed database up to July 2018. Subsequently, the answers to the questions of the recommendations were devised, and each reference selected presented the respective level of recommendation and strength of scientific evidence. The final recommendations for making up the final text were worded by the coordinators.

The Role of IL-17 in the Pathogenesis of Psoriasis and Update on IL-17 Inhibitors for the Treatment of Plaque Psoriasis

BACKGROUND

Major advances have been made in the understanding of the pathophysiology of psoriasis.

OBJECTIVES

The authors review the role of interleukin (IL) 17 in the pathogenesis of psoriasis and provide updates on approved and investigational therapies targeting IL-17 and the IL-17 receptor.

METHODS

A PubMed search was performed for relevant literature.

CONCLUSION

The IL-23/Th17 signaling pathway (including IL-17) plays a central role in the pathogenesis of psoriasis. Biologic agents that block IL-17 (secukinumab and ixekizumab) or its receptor (brodalumab) are effective and safe for the treatment of psoriasis.

Statistical reporting in randomized controlled trials from the dermatology literature: a review of 44 dermatology journals

BACKGROUND

The validity of randomized controlled trials (RCTs) is determined by several statistical factors.

OBJECTIVES

To determine the level of recent statistical reporting in RCTs from the dermatology literature.

METHODS

We searched MEDLINE for all RCTs published between 1 May 2013 and 1 May 2014 in 44 dermatology journals.

RESULTS

Two hundred and ten articles were screened, of which 181 RCTs from 27 journals were reviewed. Primary study outcomes were met in 122 (67.4%) studies. Sample size calculations and beta values were reported in 52 (28.7%) and 48 (26.5%) studies, respectively, and nonsignificant findings were supported in only 31 (17.1%). Alpha values were reported in 131 (72.4%) of studies with 45 (24.9%) having two-sided P-values, although adjustment for multiple statistical tests was performed in only 16 (9.9% of studies with ≥ two statistical tests performed). Sample size calculations were performed based on a single outcome in 44 (86.3%) and multiple outcomes in six (11.8%) studies. However, among studies that were powered for a single primary outcome, 20 (45.5%) made conclusions based on multiple primary outcomes. Twenty-one (41.2%) studies relied on secondary/unspecified outcomes. There were no differences for primary outcome being met (Chi-square, P = 0.29), sample size calculations (P ≥ 0.55), beta values (P = 0.89), alpha values (P = 0.65), correction for multiple statistical testing (P = 0.59), two-sided alpha (P = 0.64), support of nonsignificant findings (Fisher's exact, P = 0.23) based on the journal's impact factor.

CONCLUSIONS

Levels of statistical reporting are low in RCTs from the dermatology literature. Future work is needed to improve these levels of reporting.

Brodalumab: an evidence-based review of its potential in the treatment of moderate-to-severe psoriasis

Advances in knowledge regarding the pathogenesis of psoriasis have allowed the development of a new class of agents known as biologic drugs. Data confirm that T helper (Th)17 and interleukin (IL)-17 signaling has a crucial role in the pathogenesis of the disease. High levels of IL-17 and Th17-related cytokines have been reported in psoriasis, leading to the suggestion of agents targeting IL-17 as a potential therapeutic strategy in psoriasis. Brodalumab is a human monoclonal antibody that targets IL-17 receptor A, blocking the effects of IL-17A, IL-17F, and IL-17E. Data from Phase I and Phase II clinical trials indicate that brodalumab has a favorable safety and tolerability profile, with strong clinical activity, suggesting that it is a potential tool for use in the treatment of moderate-to-severe psoriasis.

Biomarkers of psoriasis severity and therapy monitoring

Psoriasis is a chronic, recurrent inflammatory cutaneous disease. Psoriasis patients alternate between periods of remission and periods of exacerbation of the disease. Usually, psoriasis severity is clinically evaluated using tools like Psoriasis Area and Severity Index that present some limitations and subjectivity. Clinicians select the therapy according to psoriasis severity, aiming that patients achieve longer remission periods and improve their quality of life. Biological markers for diagnosis and prognosis of psoriasis help to establish its severity and to monitor the therapeutic response; moreover, biomarkers of psoriasis assist clinicians in their therapeutic decision to treat psoriasis and to choose earlier and more adequate therapeutic strategies, avoiding or minimising worsening of psoriasis. With these markers, they would be able to monitor therapeutics, avoiding unnecessary therapeutic surcharge or changes to a more aggressive therapy. As any attempt to identify these biomarkers should be encouraged, in this review, we will debate published data concerning the proposal of biomarkers to evaluate severity and response to treatment of psoriasis vulgaris.
