Huang K, Si Y, Guo C, Hu J. Recent advances of electrospun strategies in topical products encompassing skincare and dermatological treatments. Adv Colloid Interface Sci 2024; 331:103236. [PMID: 38917594 DOI: 10.1016/j.cis.2024.103236] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/21/2023] [Revised: 03/25/2024] [Accepted: 06/12/2024] [Indexed: 06/27/2024]
Abstract
As the potential applications of electrospinning in healthcare continue to be explored, along with advancements in industrial-scale solutions and the emergence of portable electrospinning devices, some researchers have explored electrospinning technology in topical products, including its application in skincare, such as facial masks, beauty patches, sunscreen, and dermatological treatments for conditions like atopic dermatitis, psoriasis, acne, skin cancer, etc. In this review, we first outline the fundamental principles of electrospinning and provide an overview of existing solutions for large-scale production and the components and functionalities of portable spinning devices. Based on the essential functionalities required for skincare products and the mechanisms and treatment methods for the aforementioned dermatological diseases, we summarize the potential advantages of electrospinning technology in these areas, including encapsulation, sustained release, large surface area, and biocompatibility, among others. Furthermore, considering the further commercialization and clinical development of electrospinning technology, we offer our insights on current challenges and future perspectives in these areas, including issues such as ingredients, functionality, residue concerns, environmental impact, and efficiency issues.

Optimized dithranol-imiquimod-based transcutaneous immunization enables tumor rejection. Front Immunol 2023; 14:1238861. [PMID: 37727790 PMCID: PMC10505723 DOI: 10.3389/fimmu.2023.1238861] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/12/2023] [Accepted: 08/11/2023] [Indexed: 09/21/2023] Open
Abstract
Introduction Transcutaneous immunization (TCI) is a non-invasive vaccination method promoting strong cellular immune responses, crucial for the immunological rejection of cancer. Previously, we reported on the combined application of the TLR7 agonist imiquimod (IMQ) together with the anti-psoriatic drug dithranol as novel TCI platform DIVA (dithranol/IMQ based vaccination). In extension of this work, we further optimized DIVA in terms of drug dose, application pattern and established a new IMQ formulation. Methods C57BL/6 mice were treated on the ear skin with dithranol and IMQ-containing ointments together with ovalbumin-derived peptides. T cell responses were determined by flow cytometry and IFN-ɤ ELISpot assay, local skin inflammation was characterized by ear swelling. Results Applying the adjuvants on separate skin sites, a reduced number of specific CD8+ T cells with effector function was detectable, indicating that the local concurrence of adjuvants and peptide antigens is required for optimal vaccination. Likewise, changing the order of dithranol and IMQ resulted in an increased skin inflammatory reaction, but lower frequencies of antigen-specific CD8+ T cells indicating that dithranol is essential for superior T cell priming upon DIVA. Dispersing nanocrystalline IMQ in a spreadable formulation (IMI-Sol+) facilitated storage and application rendering comparable immune responses. DIVA applied one or two weeks after the first immunization resulted in a massive increase in antigen-specific T cells and up to a ten-fold increased memory response. Finally, in a prophylactic tumor setting, double but no single DIVA treatment enabled complete control of tumor growth, resulting in full tumor protection. Discussion Taken together, the described optimized transcutaneous vaccination method leads to the generation of a strong cellular immune response enabling the effective control of tumor growth and has the potential for clinical development as a novel non-invasive vaccination method for peptide-based cancer vaccines in humans.

A galactoside-specific Dalbergieae legume lectin from seeds of Vataireopsis araroba (Aguiar) Ducke. Glycoconj J 2023; 40:85-95. [PMID: 36287345 DOI: 10.1007/s10719-022-10082-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/23/2022] [Revised: 09/09/2022] [Accepted: 09/16/2022] [Indexed: 11/24/2022]
Abstract
The Dalbergieae lectin group encompasses several lectins with significant differences in their carbohydrate specificities and biological properties. The current work reports on the purification and characterization of a GalNAc/Gal-specific lectin from Vataireopsis araroba (Aguiar) Ducke, designated as VaL. The lectin was purified from the seeds in a single step using guar gum affinity chromatography. The lectin migrated as a single band of about 35 kDa on SDS-PAGE and, in native conditions, occurs as a homodimer. The purified lectin is stable at temperatures up to 60 °C and in a pH range from 7 to 8 and requires divalent cations for its activity. Sugar-inhibition assays demonstrate the lectin specificity towards N-acetyl-D-galactosamine, D-galactose and related sugars. Furthermore, glycan array analyses show that VaL interacts preferentially with glycans containing terminal GalNAc/Galβ1-4GlcNAc. Biological activity assays were performed using three insect cell lines: CF1 midgut cells from the spruce budworm Choristoneura fumiferana, S2 embryo cells from the fruit fly Drosophila melanogaster, and GutAW midgut cells from the corn earworm Helicoverpa zea. In vitro assays indicated a biostatic effect for VaL on CF1 cells, but not on S2 and GutAW cells. The lectin presented a biostatic effect by reducing the cell growth and inducing cell agglutination, suggesting an interaction with glycans on the cell surface. VaL has been characterized as a galactoside-specific lectin of the Dalbergieae tribe, with sequence similarity to lectins from Vatairea and Arachis.

Abstract
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.

Abstract
To enhance anthralin efficacy against psoriasis and reduce its notorious side effects, it was loaded into various liposomal and ethosomal preparations. The nanocarriers were characterized for drug encapsulation efficiency, size, morphology and compatibility between various components. Optimum formulations were dispersed in various gel bases and drug release kinetics were studied. Clinical efficacy and safety of liposomal and ethosomal Pluronic®F-127 gels were evaluated in patients having psoriasis (clinicaltrials.gov identifier is NCT03348462). Safety was assessed by recording various adverse events. Drug encapsulation efficiency ≥97.2% and ≥77% were obtained for liposomes and ethosomes, respectively. Particle sizes of 116 to 199 nm and 146 to 381 nm were observed for liposomes and ethosomes, respectively. Fourier-Transform infrared (FT-IR) spectroscopy and differential scanning calorimetry (DSC) studies confirmed the absence of interaction between anthralin and various nanocarrier components. Tested gel bases showed excellent ability to sustain drug release. At baseline, the patients had a median Psoriasis Area and Severity Index (PASI) of 3.4 for liposomes and 3.6 for ethosomes without significant difference. After treatment, mean PASI change was -68.66% and -81.84% for liposomes and ethosomes, respectively with a significant difference in favor of ethosomes. No adverse effects were detected in both groups. Anthralin ethosomes could be considered as a potential treatment of psoriasis.

The effectiveness and safety of short-contact dithranol therapy in paediatric psoriasis: a prospective comparison of regular day care and day care with telemedicine. Br J Dermatol 2014; 170:454-7.

Abstract
BACKGROUND Evidence on the effectiveness and safety of short-contact dithranol therapy in paediatric psoriasis is sparse and based only on retrospective data. The best results are achieved in a time-consuming day-care setting. OBJECTIVES To study prospectively the effectiveness and safety of short-contact dithranol therapy in paediatric psoriasis. In addition, the effectiveness, safety, duration of treatment and number of visits between regular day care and day care with telemedicine were compared. METHODS Data were collected from the prospective observational Child-CAPTURE registry of children with psoriasis. Effectiveness was measured as the mean percentage improvement in Psoriasis Area and Severity Index (PASI). Safety was assessed by recording adverse events. The number of visits and duration of treatment were reported. RESULTS For all patients a mean percentage reduction in PASI score of -69·3% was found, with no significant differences between regular day care and day care with telemedicine. The only adverse event reported was irritation of the skin. Neither the frequency of irritation during treatment nor the mean duration of treatment significantly differed between the two groups. Patients with telemedicine had significantly fewer visits. CONCLUSIONS This first prospective observational study demonstrates that short-contact dithranol therapy in paediatric psoriasis is effective and safe. Regular day care and day care with telemedicine are equally effective. Telemedicine can be of additional value as it is less time consuming. We hope it will therefore make dithranol treatment appropriate for a larger number of children with psoriasis.

Abstract
BACKGROUND Topical therapies are a mainstay of psoriasis treatment, but they vary substantially in terms of cost. OBJECTIVES To determine the cost-effectiveness and optimal treatment sequence for psoriasis of the trunk, limbs and scalp. METHODS Probabilities of response from a network meta-analysis were used to determine the short-term efficacy of topical therapies. Longer-term outcomes, including relapse, were informed by published evidence and clinical opinion. Benefits of treatment were measured as quality-adjusted life years (QALYs). Direct costs included topical agents, primary and secondary care visits and second-line therapies for treatment failures. RESULTS For the trunk and limbs, initial treatment with a two-compound formulation (TCF) product containing vitamin D and potent corticosteroid provided the most QALYs, followed by separate morning and evening application of vitamin D and potent corticosteroid [two-compound application, TCA (am/pm)], and then twice-daily potent corticosteroids. The use of twice-daily potent corticosteroids was the most cost-effective first-line strategy (incremental cost-effectiveness ratio £ 20,000 per QALY), followed by TCA (am/pm) (£ 22,658 per QALY) and TCF product (£ 179,439 per QALY). For scalp psoriasis, initial treatment with very potent corticosteroids generated the most QALYs, followed by TCF product and then potent corticosteroids. Very potent corticosteroids were the most cost-effective treatment but, if too aggressive, potent corticosteroids were optimal followed by TCF product (£ 219,846 per QALY). The cost-effectiveness of second- and third-line topical agents varied with the assumptions made. CONCLUSIONS Potent corticosteroids, used alone or in combination with vitamin D, are the most cost-effective treatment for patients with psoriasis of the trunk and limbs. Potent or very potent corticosteroids are the most cost-effective treatment for patients with scalp psoriasis.

Abstract
BACKGROUND Chronic plaque psoriasis is the most common type of psoriasis, and it is characterised by redness, thickness, and scaling. First-line management of chronic plaque psoriasis is with topical treatments, including vitamin D analogues, topical corticosteroids, tar-based preparations, dithranol, salicylic acid, and topical retinoids. OBJECTIVES To compare the effectiveness, tolerability, and safety of topical treatments for chronic plaque psoriasis, relative to placebo, and to similarly compare vitamin D analogues (used alone or in combination) with other topical treatments. SEARCH METHODS We updated our searches of the following databases to February 2011: the Cochrane Skin Group Specialised Register, CENTRAL in The Cochrane Library (2011, Issue 2), MEDLINE (from 1948), EMBASE (from 1980), Science Citation Index (from 2008), Conference Proceedings Citation Index - Science (from 2008), BIOSIS (from 1993), Dissertation Abstracts via DialogClassic (all publication years), and Inside Conferences (all publication years).We identified ongoing and unpublished studies from the UK Clinical Research Network Study Portfolio and the metaRegister of Controlled Trials. We checked the bibliographies of published studies and reviews for further references to relevant trials, and we contacted trialists and companies for information about newly published studies.A separate search for adverse effects was undertaken in February 2011 using MEDLINE and EMBASE (from 2005).Final update searches for both RCTs and adverse effects were undertaken in August 2012. Although it has not been possible to incorporate RCTs and adverse effects studies identified through these final searches within this review, we will incorporate these into the next update. SELECTION CRITERIA Randomised trials comparing active topical treatments against placebo or against vitamin D analogues (used alone or in combination) in people with chronic plaque psoriasis. DATA COLLECTION AND ANALYSIS One author extracted study data and assessed study quality. A second author checked these data. We routinely contacted trialists and companies for missing data. We also extracted data on withdrawals and on local and systemic adverse events. We defined long-term trials as those with a duration of at least 24 weeks. MAIN RESULTS This update added 48 trials and provided evidence on 7 new active treatments. In total, the review included 177 randomised controlled trials, with 34,808 participants, including 26 trials of scalp psoriasis and 6 trials of inverse psoriasis, facial psoriasis, or both. The number of included studies counted by Review Manager (RevMan) is higher than these figures (190) because we entered each study reporting a placebo and an active comparison into the 'Characteristics of included studies' table as 2 studies.When used on the body, most vitamin D analogues were significantly more effective than placebo, with the standardised mean difference (SMD) ranging from -0.67 (95% CI -1.04 to -0.30; 1 study, 119 participants) for twice-daily becocalcidiol to SMD -1.66 (95% CI -2.66 to -0.67; 1 study, 11 participants) for once-daily paricalcitol. On a 6-point global improvement scale, these effects translate into 0.8 and 1.9 points, respectively. Most corticosteroids also performed better than placebo; potent corticosteroids (SMD -0.89; 95% CI -1.06 to -0.72; I² statistic = 65.1%; 14 studies, 2011 participants) had smaller benefits than very potent corticosteroids (SMD -1.56; 95% CI -1.87 to -1.26); I² statistic = 81.7%; 10 studies, 1264 participants). On a 6-point improvement scale, these benefits equate to 1.0 and 1.8 points, respectively. Dithranol, combined treatment with vitamin D/corticosteroid, and tazarotene all performed significantly better than placebo.Head-to-head comparisons of vitamin D for psoriasis of the body against potent or very potent corticosteroids had mixed findings. For both body and scalp psoriasis, combined treatment with vitamin D and corticosteroid performed significantly better than vitamin D alone or corticosteroid alone. Vitamin D generally performed better than coal tar, but findings relative to dithranol were mixed. When applied to psoriasis of the scalp, vitamin D was significantly less effective than both potent corticosteroids and very potent corticosteroids. Indirect evidence from placebo-controlled trials supported these findings.For both body and scalp psoriasis, potent corticosteroids were less likely than vitamin D to cause local adverse events, such as burning or irritation. Combined treatment with vitamin D/corticosteroid on either the body or the scalp was tolerated as well as potent corticosteroids, and significantly better than vitamin D alone. Only 25 trials assessed clinical cutaneous dermal atrophy; few cases were detected, but trials reported insufficient information to determine whether assessment methods were robust. Clinical measurements of dermal atrophy are insensitive and detect only the most severe cases. No comparison of topical agents found a significant difference in systemic adverse effects. AUTHORS' CONCLUSIONS Corticosteroids perform at least as well as vitamin D analogues, and they are associated with a lower incidence of local adverse events. However, for people with chronic plaque psoriasis receiving long-term treatment with corticosteroids, there remains a lack of evidence about the risk of skin dermal atrophy. Further research is required to inform long-term maintenance treatment and provide appropriate safety data.

Abstract
Psoriasis vulgaris is a common and often chronic inflammatory skin disease. The incidence of psoriasis in Western industrialized countries ranges from 1.5% to 2%. Patients afflicted with severe psoriasis vulgaris may experience a significant reduction in quality of life. Despite the large variety of treatment options available, surveys have shown that patients still do not received optimal treatments. To optimize the treatment of psoriasis in Germany, the Deutsche Dermatologi sche Gesellschaft (DDG) and the Berufsverband Deutscher Dermatologen (BVDD) have initiated a project to develop evidence-based guidelines for the management of psoriasis. They were first published in 2006 and updated in 2011. The Guidelines focus on induction therapy in cases of mild, moderate and severe plaque-type psoriasis in adults including systemic therapy, UV therapy and topical therapies. The therapeutic recommendations were developed based on the results of a systematic literature search and were finalized during a consensus meeting using structured consensus methods (nominal group process).

Abstract
BACKGROUND Despite the availability of newer topical treatments, classical topical treatments for chronic plaque psoriasis still have an important position for selected patient populations. The vast majority of patients are treated with a combination of topicals. The question arises: what is the evidence behind these approaches? OBJECTIVES To systematically review all available literature on efficacy and safety of combinations of classical topical treatments in chronic plaque psoriasis, including all combinations with dithranol, coal tar and penetration enhancers, and ultimately, to propose recommendations for combination treatment. METHODS Standardized literature searches in PubMed, EMBASE and the Cochrane Controlled Clinical Trial Register, and allocation of the degree of evidence was carried out. RESULTS In total 2918 publications on topical combination therapy were revealed, of which 48 articles on combinations of classical treatments. In this article, the results concerning the 19 included publications are stated. The majority of combination regimens is at least as effective as monotherapies, and is generally well tolerated. CONCLUSIONS Methods of classical treatments are not standardized and different protocols in different treatment settings are used. Therefore the interpretation of study results cannot be generalized. Most evidence was found to recommend the use of a combination regimen of topical corticosteroids and salicylic acid, above monotherapy with either component. Also, the combinations of dithranol with superpotent corticosteroids or with coal tar may be preferred above both monotherapies. In case first-line treatments and systemic therapies are not effective or contraindicated, combinations of classical topicals may provide an important opportunity.

Abstract
OBJECTIVE The efficacy of the two-compound formulation (TCF) product containing calcipotriol and betamethasone dipropionate applied once daily in psoriasis has been demonstrated in phase III trials but no randomised clinical trial comparing all commonly used topical treatments exists. The aim of the study was to compare the efficacy of once-daily use of the TCF product relative to other commonly used topical agents in plaque psoriasis. RESEARCH DESIGN AND METHODS Data on change in Psoriasis Area and Severity Index (PASI) score from baseline and PASI 75 (percentage of patients achieving a 75% reduction in PASI score), after 4 weeks of treatment were obtained by means of a systematic literature review of randomised controlled trials and synthesised with a Bayesian mixed treatment comparison meta-analysis. RESULTS Relative to all active interventions, except for the unlicensed twice-daily application of the TCF product, the TCF once daily showed a greater efficacy based on PASI 75 response (relative risk ranging from 1.22 to 3.18) and improvement in PASI score from baseline (difference in % CFB PASI between TCF once daily and other active interventions ranged from 4.01 to 49.68). CONCLUSION Among topical therapies evaluated, TCF once daily can be considered the most efficacious treatment for plaque psoriasis.

Abstract
Botanical extracts and single compounds are increasingly used in cosmetics but also in over-the-counter drugs and food supplements. The focus of the present review is on controlled clinical trials with botanicals in the treatment of acne, inflammatory skin diseases, skin infections, UV-induced skin damage, skin cancer, alopecia, vitiligo, and wounds. Studies with botanical cosmetics and drugs are discussed, as well as studies with botanical food supplements. Experimental research on botanicals was considered to a limited extent when it seemed promising for clinical use in the near future. In acne therapy, Mahonia, tea tree oil, and Saccharomyces may have the potential to become standard treatments. Mahonia, Hypericum, Glycyrrhiza and some traditional Chinese medicines appear promising for atopic dermatitis. Some plant-derived substances like dithranol and methoxsalen (8-methoxypsoralen) [in combination with UVA] are already accepted as standard treatments in psoriasis; Mahonia and Capsicum (capsaicin) are the next candidates suggested by present evidence. Oral administration and topical application of antioxidant plant extracts (green and black tea, carotenoids, coffee, and many flavonoids from fruits and vegetables) can protect skin from UV-induced erythema, early aging, and irradiation-induced cancer. Hair loss and vitiligo are also traditional fields of application for botanicals. According to the number and quality of clinical trials with botanicals, the best evidence exists for the treatment of inflammatory skin diseases, i.e. atopic dermatitis and psoriasis. However, many more controlled clinical studies are needed to determine the efficacy and risks of plant-derived products in dermatology. Safety aspects, especially related to sensitization and photodermatitis, have to be taken into account. Therefore, clinicians should not only be informed of the beneficial effects but also the specific adverse effects of botanicals used for dermatologic disorders and cosmetic purposes.

Abstract
Plant extracts and isolated compounds are increasingly used in cosmetics and food supplements to improve skin conditions. We first introduce the positive plant monographs with dermatological relevance of the former German Commission E. Subsequently clinical studies with botanicals for atopic dermatitis, psoriasis, acne, condylomata acuminata and herpes simplex are discussed. The best studies have been conducted with atopic dermatitis and psoriasis patients. Mahonia aquifolium, Hypericum perforatum, Glycyrrhiza glabra and certain traditional Chinese therapies have been shown to be effective in the treatment of atopic dermatitis. Mahonia aquifolium, Indigo naturalis and Capsicum frutescens are effective treatments for psoriasis. Green tea extract and tea tree oil have been investigated in the treatment of acne. Podophyllin and green tea extract are effective treatments for condylomata acuminata. Balm mint and a combination of sage and rhubarb have been shown to be effective in the treatment of herpes simplex in proof of concept studies.

Abstract
BACKGROUND Chronic plaque psoriasis is the most common type of psoriasis and is characterised by redness, thickness and scaling. First line management of chronic plaque psoriasis is with topical treatments, including vitamin D analogues, topical corticosteroids, tar-based preparations, dithranol, salicylic acid and topical retinoids. OBJECTIVES To compare the effectiveness, tolerability and safety of topical treatments for chronic plaque psoriasis with placebo; to compare vitamin D analogues with other topical treatments. SEARCH STRATEGY The Cochrane Skin Group's Trials Register was searched (2004/12). To update an unpublished 2002 review we also searched CENTRAL in The Cochrane Library (Issue 1,2005); MEDLINE (to 2005/02); EMBASE (to 2005/08); Science Citation Index (to 2005); Biosis (to 2005); Dissertation Abstracts (all publication years); Inside Conferences (all publication years); SIGLE (to 2005); National Research Register (all projects with a start date of 2001 to 2005); metaRegister of Current Controlled Trials. SELECTION CRITERIA Randomised trials comparing treatments against placebo or against vitamin D analogues in people with chronic plaque psoriasis. DATA COLLECTION AND ANALYSIS One author extracted study data and assessed study quality. A second author checked these data. We routinely contacted triallists and companies for missing data. We extracted data on withdrawals and adverse events. MAIN RESULTS The review included 131 RCTs with 21,448 participants. Vitamin D was significantly more effective than placebo, although there was a wide variation in effect size with the standardised mean difference (SMD) ranging from -0.82 (95% CI -1.34 to -0.29) to -1.90 (95% CI -2.09 to -1.71). With one exception, all corticosteroids performed better than placebo, with potent corticosteroids (SMD: -0.95 (95% CI: -1.11 to -0.80; I(2): 61.1%; 17 studies; 2386 participants)) having smaller benefits than very potent corticosteroids (SMD: -1.29 (95% CI: -1.45 to -1.13; I(2): 53.2%; 11 studies; 1571 participants)). Dithranol and tazarotene performed better than placebo. Head-to-head comparisons of vitamin D against potent or very potent corticosteroids found no significant differences. However, combined treatment with vitamin D /corticosteroid performed significantly better than either vitamin D alone or corticosteroid alone. Vitamin D performed better than coal tar, but findings relative to dithranol were mixed. Potent corticosteroids were less likely than vitamin D to cause local adverse events. No comparison of topical agents found a significant difference in systemic adverse effects. AUTHORS' CONCLUSIONS Corticosteroids perform as well as vitamin D analogues and are associated with a lower incidence of local adverse events. Further research is required to inform long-term maintenance treatment.
