Targeting antibody-mediated complement-independent mechanism in bullous pemphigoid with diacerein.

BACKGROUND: Bullous pemphigoid (BP) is an antibody-mediated blistering disease predominantly affecting the elderly. The pathogenesis involves both complement-dependent and complement-independent mechanisms. The therapeutic potential of targeting complement-independent mechanism has not yet been determined. The mainstay of treatment, corticosteroid, has many side effects, indicating the needs of better treatments. OBJECTIVE: We tempted to establish an in vitro model of BP which resembles complement-independent mechanism and to examine the therapeutic potential of a novel anti-inflammatory agent, diacerein. METHODS: Cultured HaCaT cells were treated with purified antibodies from BP patients, with or without diacerein to measure the cell interface presence of BP180, protein kinase C, and the production of proinflammatory cytokines. An open-label, randomized, phase 2 trial was conducted to compare topical diacerein and clobetasol ointments in patients with mild-to-moderate BP (NCT03286582). RESULTS: The reduced presentation of BP180 at cell interface after treating with BP autoantibodies was noticed in immunofluorescence and western blotting studies. The phenomenon was restored by diacerein. Diacerein also reduced the autoantibody-induced increase of pro-inflammatory cytokines. Reciprocal changes of BP180 and protein kinase C at the cell interface were found after treating with BP autoantibodies. This phenomenon was also reversed by diacerein in a dose-dependent manner. The phase 2 trial showed that topical diacerein reduced the clinical symptoms which were comparable to those of topical clobetasol. CONCLUSION: Diacerein inhibited BP autoantibody-induced reduction of BP180 and production of proinflammatory cytokines in vitro and showed therapeutic potential in patients with BP. It is a novel drug worthy of further investigations.

The ameliorative effects of topical gemifloxacin alone or in combination with clobetasol propionate on imiquimod-induced model of psoriasis in mice.

Psoriasis is a lifelong immune-driven skin condition characterized by excessive epidermal overgrowth and inflammatory cell infiltration. Gemifloxacin is a fourth-generation fluoroquinolone with improved immunomodulatory and anti-inflammatory properties that are believed to possess an attractive role in psoriasis via suppressing the production of cytokines, chemokines, and eosinophil and neutrophil chemotaxis. The aim of this research is to investigate the ameliorative effects of prolonged topical gemifloxacin (GMF) alone and combined with clobetasol propionate (CLO) on an imiquimod (IMQ)-induced mouse model of psoriasis. Forty-eight Swiss albino mice were divided into six groups of eight. All groups except the negative controls got 62.5 mg of IMQ 5% topically for 8 days. Mice in the control group (controls) got Vaseline instead. Following the induction in the IMQ 5% group, mice in treatment groups CLO 0.05, GMF 1%, GMF 3%, and CLO + GMF obtained clobetasol propionate 0.05%, GMF 1% and 3%, and a combination of both, respectively, for an additional 8 days, rendering the experiment 16 days long. Our results revealed that gemifloxacin alleviated erythematous, thickened, and scaly psoriatic lesions and inhibited the tissue level of inflammatory cytokines, including interleukin (IL)-8, IL-17A, IL-23, tumor necrosis factor-α (TNF-α), and transforming growth factor-ß1 (TGF-ß1). The anti-inflammatory effect also occurred by hindering nuclear factor-kappa B (NF-κB) signaling and reversing histopathological problems. Gemifloxacin acts effectively in mitigating psoriasis-associated lesions and restricting NF-κB-mediated inflammation, recommending gemifloxacin as a promising adjuvant candidate for additional studies on the long-term treatment of autoimmune and autoinflammatory dermatoses like psoriasis.

Divergent Chemo- and Biocatalytic Route to 16ß-Methylcorticoids: Asymmetric Synthesis of Betamethasone Dipropionate, Clobetasol Propionate, and Beclomethasone Dipropionate.

16ß-Methylcorticoids are among the most important glucocorticoid steroids for the treatment of various dermatological disorders, respiratory infections, and other allergic reactions elicited during inflammatory responses of the human body. Betamethasone dipropionate, clobetasol propionate, and beclomethasone dipropionate are particularly noteworthy for their synthetic intractability. Despite five decades of research, these 16ß-methylcorticoids have remained challenging synthetic targets owing to insurmountable issues of reactivity, selectivity, and cost efficiency associated with all previously explored strategies. We herein report our practicability-oriented strategy toward the unified stereoselective synthesis of 16ß-methylcorticoids in 12.6-14.0 % overall yield from commercially available 9α-hydroxyandrost-4-ene-3,17-dione (9α-OH-AD). In this approach, the chiral C16ß-Me and C17α-OH groups of the corticosteroid D ring were installed via a substrate-controlled diastereo- and enantioselective Mn-catalyzed oxidation-reduction hydration of Δ4,9(11),16 -triene-3,20-dione. The C1-C2 double bond of the corticosteroid A ring was constructed using an unprecedented engineered 3-ketosteroid-Δ1 -dehydrogenase (MK4-KstD)-catalyzed regioselective Δ1 -dehydrogenation of Δ4,9(11) -diene-3,21-dione. This strategy provides a general method and a key precursor for the divergent synthesis of a variety of glucocorticoids and related steroidal drugs.

A Systematic Review and Bayesian Network Meta-Analysis of Medical Therapies for Lichen Planopilaris.

BACKGROUND: Lichen planopilaris (LPP) is a primary chronic lymphocytic cutaneous disorder that selectively destroys the hair follicles, resulting in scarring alopecia. Unfortunately, current available treatments are not fully effective to stop hair loss, and the level of evidence for medical interventions is weak. OBJECTIVES: The present article aimed to determine the efficacy of the different medical interventions in LPP through a network meta-analysis (NMA). METHODS: A systematic review and meta-analysis were performed including randomized trials that report the outcomes of lichen planopilaris activity index (LPPAI). These articles were pooled and a NMA was conducted. RESULTS: A total of seven studies were identified and included in meta-analysis, comprising 251 LPP patients. The NMA showed the mean difference in LLPAI was significantly superior with the combination of clobetasol plus N-acetylcysteine (mean difference: -2.0, 95% CI = -3.43 to -0.51) and the combination of clobetasol plus pentoxifylline (mean difference: -1.62, 95% CI = -3.0 to -0.25) compared to the treatment of reference (clobetasol). The NMA showed cyclosporine (mean difference: 2.05 95% CI = 0.68-3.49), methotrexate (mean difference: 1.95 95% CI = 1.23-3.17), the combination of methotrexate plus prednisolone (mean difference: 1.56 95% CI = 0.25-2.96) were significantly worse than hydroxychloroquine according to the differences in LLPAI. CONCLUSION: This work is the first NMA in LPP and hence, it can be helpful in serving as an initial step toward better evidence-based decisions in the treatment of this challenging condition. We propose a triple-combined approach consisting of topical clobetasol, hydroxychloroquine, and N-acetylcysteine as resulted in the most effective approach. Considering the poor outcomes observed with pioglitazone, mycophenolate mofetil, and cyclosporine, it is advisable to contemplate the use of these medications in patients who have not responded adequately to more efficacious alternatives.

Nd:YAG/Er:YAG dual laser compared with topical steroid to treat vulvar lichen sclerosus: A randomised controlled trial.

OBJECTIVE: To evaluate the efficacy and safety of a novel non-ablative Nd:YAG/Er:YAG dual laser treatment for vulvar lichen sclerosus (LS) in comparison with the recommended first-line therapy with topical steroid. DESIGN: A randomised investigator-initiated active-controlled trial. SETTING: Single tertiary referral centre. POPULATION: Women with vulvar LS. METHODS: Randomisation (2:1) to Nd:YAG/Er:YAG laser therapy or topical clobetasol proprionate therapy. Four laser treatments at 0, 1, 2 and 4 months or decreasing doses of steroid for 6 months. MAIN OUTCOME MEASURES: The primary outcome was the change in objective validated clinical LS score in the laser arm between baseline and 6 months. Secondary outcomes were laser tolerability/safety, symptom scores and patient satisfaction. RESULTS: Sixty-six women were included, 44 in the laser group and 22 in the steroid group. The total LS score decreased by -2.34 ± 1.20 (95% CI -2.71 to -1.98) in women treated with laser compared with a decrease of -0.95 ± 0.90 (95% CI -1.35 to -0.56) in those receiving steroid applications (p < 0.001). Laser treatment was safe and well tolerated. Subjective severity scores (on visual analogue scale) and vulvovaginal symptoms questionnaire scores improved similarly for the laser and steroid arms without significant differences between the two treatments. Patient satisfaction was higher in the laser arm than in the steroid arm (p = 0.035). CONCLUSIONS: Non-ablative dual Nd:YAG/Er:YAG laser therapy was safe and significantly improved clinical outcome and subjective symptoms at the 6-month follow up. This suggests that laser may be a promising alternative to corticosteroid therapy. However, the authors caution regular follow ups because of the premalignant nature of the disease.

Interventions for bullous pemphigoid.

BACKGROUND: Bullous pemphigoid (BP) is the most common autoimmune blistering disease. Oral steroids are the standard treatment. We have updated this review, which was first published in 2002, because several new treatments have since been tried. OBJECTIVES: To assess the effects of treatments for bullous pemphigoid. SEARCH METHODS: We updated searches of the following databases to November 2021: Cochrane Skin Specialised Register, CENTRAL, MEDLINE, and Embase. We searched five trial databases to January 2022, and checked the reference lists of included studies for further references to relevant randomised controlled trials (RCTs). SELECTION CRITERIA: RCTs of treatments for immunofluorescence-confirmed bullous pemphigoid. DATA COLLECTION AND ANALYSIS: At least two review authors, working independently, evaluated the studies against the review's inclusion criteria and extracted data from included studies. Using GRADE methodology, we assessed the certainty of the evidence for each outcome in each comparison. Our primary outcomes were healing of skin lesions and mortality. MAIN RESULTS: We identified 14 RCTs (1442 participants). The main treatment modalities assessed were oral steroids, topical steroids, and the oral anti-inflammatory antibiotic doxycycline. Most studies reported mortality but adverse events and quality of life were not well reported. We decided to look at the primary outcomes 'disease control' and 'mortality'. Almost all studies investigated different comparisons; two studies were placebo-controlled. The results are therefore based on a single study for each comparison except azathioprine. Most studies involved only small numbers of participants. We assessed the risk of bias for all key outcomes as having 'some concerns' or high risk, due to missing data, inappropriate analysis, or insufficient information. Clobetasol propionate cream versus oral prednisone Compared to oral prednisone, clobetasol propionate cream applied over the whole body probably increases skin healing at day 21 (risk ratio (RR 1.08, 95% confidence interval (CI) 1.03 to 1.13; 1 study, 341 participants; moderate-certainty evidence). Skin healing at 21 days was seen in 99.8% of participants assigned to clobetasol and 92.4% of participants assigned to prednisone. Clobetasol propionate cream applied over the whole body compared to oral prednisone may reduce mortality at one year (RR 0.73, 95% CI 0.53 to 1.01; 1 study, 341 participants; low-certainty evidence). Death occurred in 26.5% (45/170) of participants assigned to clobetasol and 36.3% (62/171) of participants assigned to oral prednisone. This study did not measure quality of life. Clobetasol propionate cream may reduce risk of severe complications by day 21 compared with oral prednisone (RR 0.65, 95% CI 0.50 to 0.86; 1 study, 341 participants; low-certainty evidence). Mild clobetasol propionate cream regimen (10 to 30 g/day) versus standard clobetasol propionate cream regimen (40 g/day) A mild regimen of topical clobetasol propionate applied over the whole body compared to the standard regimen probably does not change skin healing at day 21 (RR 1.00, 95% CI 0.97 to 1.03; 1 study, 312 participants; moderate-certainty evidence). Both groups showed complete healing of lesions at day 21 in 98% participants. A mild regimen of topical clobetasol propionate applied over the whole body compared to the standard regimen may not change mortality at one year (RR 1.00, 95% CI 0.75 to 1.32; 1 study, 312 participants; low-certainty evidence), which occurred in 118/312 (37.9%) participants. This study did not measure quality of life. A mild regimen of topical clobetasol propionate applied over the whole body compared to the standard regimen may not change adverse events at one year (RR 0.94, 95% CI 0.78 to 1.14; 1 study, 309 participants; low-certainty evidence). Doxycycline versus prednisolone Compared to prednisolone (0.5 mg/kg/day), doxycycline (200 mg/day) induces less skin healing at six weeks (RR 0.81, 95% CI 0.72 to 0.92; 1 study, 213 participants; high-certainty evidence). Complete skin healing was reported in 73.8% of participants assigned to doxycycline and 91.1% assigned to prednisolone. Doxycycline compared to prednisolone probably decreases mortality at one year (RR 0.25, 95% CI 0.07 to 0.89; number needed to treat for an additional beneficial outcome (NNTB) = 14; 1 study, 234 participants; moderate-certainty evidence). Mortality occurred in 2.4% (3/132) of participants with doxycycline and 9.7% (11/121) with prednisolone. Compared to prednisolone, doxycycline improved quality of life at one year (mean difference 1.8 points lower, which is more favourable on the Dermatology Life Quality Index, 95% CI 1.02 to 2.58 lower; 1 study, 234 participants; high-certainty evidence). Doxycycline compared to prednisolone probably reduces severe or life-threatening treatment-related adverse events at one year (RR 0.59, 95% CI 0.35 to 0.99; 1 study, 234 participants; moderate-certainty evidence). Prednisone plus azathioprine versus prednisone It is unclear whether azathioprine plus prednisone compared to prednisone alone affects skin healing or mortality because there was only very low-certainty evidence from two trials (98 participants). These studies did not measure quality of life. Adverse events were reported in a total of 20/48 (42%) participants assigned to azathioprine plus prednisone and 15/44 (34%) participants assigned to prednisone. Nicotinamide plus tetracycline versus prednisone It is unclear whether nicotinamide plus tetracycline compared to prednisone affects skin healing or mortality because there was only very low-certainty evidence from one trial (18 participants). This study did not measure quality of life. Fewer adverse events were reported in the nicotinamide group. Methylprednisolone plus azathioprine versus methylprednisolone plus dapsone It is unclear whether azathioprine plus methylprednisolone compared to dapsone plus methylprednisolone affects skin healing or mortality because there was only very low-certainty evidence from one trial (54 participants). This study did not measure quality of life. A total of 18 adverse events were reported in the azathioprine group and 13 in the dapsone group. AUTHORS' CONCLUSIONS: Clobetasol propionate cream applied over the whole body is probably similarly effective as, and may cause less mortality than, oral prednisone for treating bullous pemphigoid. Lower-dose clobetasol propionate cream applied over the whole body is probably similarly effective as standard-dose clobetasol propionate cream and has similar mortality. Doxycycline is less effective but causes less mortality than prednisolone for treating bullous pemphigoid. Other treatments need further investigation.

Fixed-combination halobetasol propionate and tazarotene topical lotion decreases TNF-α and IL-17A levels in psoriatic lesions.

OBJECTIVE: Fixed-combination halobetasol propionate (0.01%) and tazarotene (0.045%) lotion (HP/TAZ) is approved for the treatment of plaque psoriasis in adults, with a demonstrated efficacy and safety profile in phase 3 trials. This study examined the effect of HP/TAZ on the reduction of tumor necrosis factor alpha (TNF-α) and interleukin 17 A (IL-17A) and its correlation to psoriasis improvement. MATERIALS AND METHODS: Ten adults with mild-to-moderate plaque psoriasis and 2 symmetrical plaques self-applied HP/TAZ (treated plaque) or vehicle lotion (untreated plaque) for 12 weeks. At baseline and each study visit (weeks 2, 4, 8, and 12), Investigator's Global Assessment (IGA) score and erythema, scaling, and induration were assessed. Additionally, D-squame tape strips were utilized to quantify TNF-α and IL-17A in target lesions by enzyme-linked immunosorbent assay. RESULTS: Significant improvements in mean IGA score in HP/TAZ-treated compared with untreated plaques were evident at week 2 and maintained through week 12 (p < 0.003). HP/TAZ significantly reduced TNF-α levels at weeks 4 through 12 (p < 0.03) and IL-17A levels at weeks 2 through 8 (p < 0.05) in treated compared with untreated plaques. CONCLUSIONS: HP/TAZ was highly effective in treating psoriasis plaques and, although HP/TAZ is not a biologic, effectively reduced cytokine-associated inflammatory markers that drive psoriatic disease.

Tough Adhesive Hydrogel for Intraoral Adhesion and Drug Delivery.

Oral lichen planus (OLP) and recurrent aphthous stomatitis (RAS) are common chronic inflammatory conditions, manifesting as painful oral lesions that negatively affect patients' quality of life. Current treatment approaches are mainly palliative and often ineffective due to inadequate contact time of the therapeutic agent with the lesions. Here, we developed the Dental Tough Adhesive (DenTAl), a bioinspired adhesive patch with robust mechanical properties, capable of strong adhesion against diverse wet and dynamically moving intraoral tissues, and extended drug delivery of clobetasol-17-propionate, a first-line drug for treating OLP and RAS. DenTAl was found to have superior physical and adhesive properties compared to existing oral technologies, with ~2 to 100× adhesion to porcine keratinized gingiva and ~3 to 15× stretchability. Clobetasol-17-propionate incorporated into the DenTAl was released in a tunable sustained manner for at least 3 wk and demonstrated immunomodulatory capabilities in vitro, evidenced by reductions in several cytokines, including TNF-α, IL-6, IL-10, MCP-5, MIP-2, and TIMP-1. Our findings suggest that DenTAl may be a promising device for intraoral delivery of small-molecule drugs applicable to the management of painful oral lesions associated with chronic inflammatory conditions.

Randomized clinical trial with fractional CO2 laser and Clobetasol in the treatment of Vulvar Lichen Sclerosus: a clinic study of feasibility.

OBJECTIVES: The main objective of the study was to describe and compare the feasibility of using fractional CO2 laser to the usual treatment with Clobetasol. Randomized clinical trials brought together 20 women from a Brazilian university hospital, 9 of them were submitted to Clobetasol treatment and 11 to laser therapy. Sociodemographic data were obtained and quality of life parameters, vulvar anatomy, self-perception and histopathological analysis of vulvar biopsies were evaluated. Evaluations were made before the beginning of the treatment, during its implementation, right after its completion (3 months), and 12 months after. The SPSS 14.0 software was used, obtaining descriptive measurements. The level of significance adopted was 5%. RESULTS: The clinical/anatomical characteristics of the vulva did not differ between the treatment groups, as much before as after its performance. There was no statistically significant difference between the treatments performed regarding the impact on the life quality of the patients. A higher satisfaction degree with the treatment was obtained with the patients in the Laser group in the third month of evaluation. Laser therapy also revealed higher occurrence of telangiectasia after treatment completion. Fractional CO2 laser has proven to be well accepted and is a promising therapeutic option. Registration number and name of trial registry The institutional review board status was approved by the Research Ethics Committee of HU/ UFJF under advisory number 2881073 and registered in the Brazilian Clinical Trials, with consent under registration RBR-4p9s5y.

Serum and salivary cytokines in patients with oral lichen planus treated with Photobiomodulation.

OBJECTIVES: To evaluate the serum and salivary levels of IL-1ß, IL-6, IL-17A, TNF-α, IL-4, and IL-10 in patients with oral lichen planus (OLP) treated with Photobiomodulation (PBM) and clobetasol propionate 0.05%. MATERIAL AND METHODS: Thirty-four OLP patients were randomized into two groups: Control (clobetasol propionate 0.05%) and PBM (660 nm, 100 mW, 177 J/cm2 , 5 s, 0.5 J per point). Serum and saliva were collected at baseline and at the end of treatment (after 30 days) and evaluated using ELISA. The cytokine results were correlated with pain, clinical subtypes, and clinical scores of OLP. RESULTS: IL-1ß, IL-6, IL-17A, TNF-α, and IL-4 levels were higher in saliva in relation to serum. IL-1ß was the most concentrated cytokine in saliva, and a positive correlation with the severity of OLP was noticed. After treatment with corticosteroid, IL-1ß in saliva decreased significantly. No modulation of all cytokines was observed after PBM. CONCLUSION: IL-1ß appears to be an important cytokine involved in OLP pathogenesis. In addition, the mechanisms of action of PBM do not seem to be linked to the modulation of pro or anti-inflammatory cytokines at the end of treatment. It is possible that this events occurred early during treatment.

Comparative study between topical steroid alone versus combined fractional Erbium:YAG laser with topical steroid in treatment of alopecia areata.

AA is a common autoimmune skin disease that causes hair loss on the scalp and sometimes other areas of the body. New therapy approaches for alopecia areata are emerging, with the goal of improving clinical outcomes. In this study, the effects of topical steroids against fractional Er:YAG laser followed by topical steroids in the treatment of alopecia areata will be compared. A total of 30 participants with alopecia areata were included in the study. Each patient's lesions were treated with one of two methods: topical clobetasol propionate or fractional Er:YAG laser followed by topical clobetasol propionate. SALT score, patient satisfaction, and dermoscopic imaging were used to evaluate therapeutic response. Both treatment modalities showed a significant clinical improvement in alopecia areata with a statistically significant reduction in the SALT score. The SALT score was more evident in the laser-steroid group. On comparing the dermoscopy findings in both treated areas before and after treatment, a significant reduction was found regarding all dermoscopic findings of alopecia areata in both modalities. Combining fractional Er:YAG laser with topical steroids is found to be a safe treatment modality and more effective than topical steroids in alopecia areata.

High-content, arrayed compound screens with rhinovirus, influenza A virus and herpes simplex virus infections.

Viruses are genetically and structurally diverse, and outnumber cells by orders of magnitude. They can cause acute and chronic infections, suppress, or exacerbate immunity, or dysregulate survival and growth of cells. To identify chemical agents with pro- or antiviral effects we conducted arrayed high-content image-based multi-cycle infection screens of 1,280 mainly FDA-approved compounds with three human viruses, rhinovirus (RV), influenza A virus (IAV), and herpes simplex virus (HSV) differing in genome organization, composition, presence of an envelope, and tropism. Based on Z'-factors assessing screening quality and Z-scores ranking individual compounds, we identified potent inhibitors and enhancers of infection: the RNA mutagen 5-Azacytidine against RV-A16; the broad-spectrum antimycotic drug Clotrimazole inhibiting IAV-WSN; the chemotherapeutic agent Raltitrexed blocking HSV-1; and Clobetasol enhancing HSV-1. Remarkably, the topical antiseptic compound Aminacrine, which is clinically used against bacterial and fungal agents, inhibited all three viruses. Our data underscore the versatility and potency of image-based, full cycle virus propagation assays in cell-based screenings for antiviral agents.

Efficacy and safety of oral pioglitazone in the management of lichen planopilaris in comparison with clobetasol: A randomized clinical trial.

Lichen planopilaris (LPP) is a scarring alopecia for which no treatment with remarkable effect has been identified. Pioglitazone has been reported as a possible therapeutic option. To compare the efficacy and safety of pioglitazone with clobetasol in LPP. This randomized, double-blind, parallel-group was conducted at Razi hospital. Patients were treated either with pioglitazone 15 mg/daily or clobetasol lotion 0.05% once at night for 6 months. Patients were visited every 2 months to assess the lichen planopilaris activity index (LPPAI) and record probable adverse events. Forty patients (mean age: 43.6 years; 62.5% female) were randomized 1:1. The mean of LPPAI at baseline and last session were 4.68 ± 1.97 and 2.59 ± 0.97 in the clobetasol group and 5.01 ± 1.71 and 3.04 ± 1.36 in the pioglitazone group, respectively. Both treatments significantly decreased the LPPAI over the two-month interval visits (p < 0.001). No significant difference in the LPPAI reduction was detected between groups. Regarding the safety profile, three clobetasol-treated patients developed folliculitis, and two in the pioglitazone group developed mild headaches. Pioglitazone effectively controlled the signs and symptoms of the LPP with no serious side effects. It can be considered a treatment option for LPP, although it was not superior to clobetasol.

Vulvar dermatoses: a cross-sectional 5-year study. Experience in a specialized vulvar unit.

BACKGROUND: Vulvar diseases are common in the general population and have a negative impact on the quality of life. OBJECTIVES: To describe our experience as dermatologists in the management of vulvar dermatosis consultations. METHODS: A retrospective observational study was conducted with patients who attended monographic vulvar consultations over a 5-year period. Clinical information was obtained from the patient's charts. RESULTS: 148 women were studied. Their mean age was 43.24 years (standard deviation: 15.15 years), with ages ranging from 4 months to 80 years. 53.4% of patients took between 2 and 5 years to seek medical attention for the first time. The most frequent diagnosis was lichen sclerosus (41.9%), irritative eczema of the vulva (14.9%), and lichen simplex chronicus (10.1%). 83.8% reported anogenital itching, 66.2% pain, and 45.9% dyspareunia. The most frequently prescribed treatment was ultra-potent topical corticosteroids (clobetasol propionate; 41.2%). Patients with lichen sclerosus were significantly older than those who presented with any of the other diseases. No differences were found in terms of either the time of disease evolution or in symptom presentation. STUDY LIMITATIONS: Retrospective study. Vulvar diseases with an infectious cause are usually managed in primary care, therefore, were not included. All patients were recruited from a single private hospital which limits the comparisons with the public health system. CONCLUSIONS: Vulvar diseases frequently occur and are associated with high morbidity. It is essential to promote the development of specific vulvar consultations in hospitals. Specialties such as dermatology, gynecology, urology, or physiotherapy must be part of these units.

A critical review of halobetasol propionate foam (0.05%) as a treatment option for adolescent plaque psoriasis.

INTRODUCTION: Halobetasol propionate foam has been established as an efficacious and easy-to-use topical treatment for adults with plaque psoriasis. Its recent approval in the United States expanded its use for adolescents from ages 12 to 17 years old. AREAS COVERED: We briefly summarize the chemistry of halobetasol and review clinical trials involving halobetasol propionate 0.05% foam to evaluate its efficacy and safety profile with a specific focus on adolescents with plaque psoriasis. EXPERT OPINION: Halobetasol propionate 0.05% foam is an effective and cosmetically elegant superpotent topical corticosteroid, with a tolerable safety profile in adolescents. The use of this foam offers another option to address patient-specific needs and preferences, adding to the toolbox of currently available treatments for adolescent psoriasis.

Evaluation of clinical efficacy of topical tacrolimus 0.1% and clobetasol propionate 0.05% in desquamative gingivitis, manifestation of oral lichen planus.

Abstract.

Adjunctive Use of Halobetasol Propionate-Tazarotene in Biologic-Experienced Patients With Psoriasis.

Not all patients with psoriasis achieve a satisfactory response to their initial biologic monotherapy. Switching to a new biologic may be associated with new safety issues and additional costs. In this study, we assessed the effectiveness and safety of adjunctive halobetasol propionate (HP) 0.01%-tazarotene (TAZ) 0.045% lotion in adult patients with moderate to severe plaque psoriasis who had been receiving biologic monotherapy for 24 weeks or more but had inadequate responses. All participants received HP-TAZ lotion once daily for 8 weeks, then once every other day for 4 weeks, in addition to their ongoing biologics. This real-world study demonstrated that HP-TAZ lotion adjunctive to ongoing biologics is safe and effective and potentially a more economical alternative to switching biologics for patients with psoriasis with inadequate responses to biologic monotherapy.
