RESUMEN

OBJECTIVE: The objective of this study was to review the safety and efficacy of deucravacitinib, a tyrosine kinase 2 (TYK2) inhibitor for moderate to severe plaque psoriasis. DATA SOURCES: Literature was reviewed from MEDLINE and Clinicaltrials.gov up to December 2022 using the terms "deucravacitinib" and "BMS-986165." STUDY SELECTION: Relevant articles in English relating to the pharmacodynamics, pharmacokinetics, efficacy, and safety of deucravacitinib were included. A total of 6 trial results were included. STUDY SELECTION AND DATA EXTRACTION: Deucravacitinib showed clinical efficacy across all the phase II and III clinical trials. Excluding the long-term extension study, there were 2248 subjects across all studies, with 63.2% of patients receiving deucravacitinib 6 mg daily. Of these subjects, the average proportion achieving a PASI 75 (a reduction of greater than 75% in the Psoriasis Area and Severity Index) at week 16 was 65.1%. Patients receiving deucravacitinib 6 mg once daily had a higher rate of achieving both PASI 75 response and a Static Physician's Global Assessment (sPGA) score of 0 or 1, compared with oral apremilast 30 mg twice daily. The safety profile of deucravacitinib includes mild adverse events (AEs), most commonly nasopharyngitis, with serious AEs reported ranging from 1.35% to 9.5%. RELEVANCE TO PATIENT CARE AND CLINICAL PRACTICE IN COMPARISON WITH EXISTING MEDICATIONS: While many available therapies for moderate to severe plaque psoriasis rely on an injectable dosage form or extensive monitoring, deucravacitinib can potentially reduce patient medication-related burden. This review summarizes the efficacy and safety of oral deucravacitinib for the treatment of severe plaque psoriasis. CONCLUSION: Deucravacitinib shows a consistent efficacy and safety profile as the first oral TYK2 inhibitor approved for adult patients with moderate to severe plaque psoriasis who are eligible for systemic therapy or phototherapy treatment.

RESUMEN

OBJECTIVE: This article reviews clinical trial data that assesses the safety, efficacy, and clinical application of spesolimab, an interleukin-36 (IL-36) blocker, for the treatment of generalized pustular psoriasis (GPP). DATA SOURCES: A review of the literature was conducted using the search terms: "spesolimab," "BI 655130," and "spevigo" in MEDLINE (PubMed) and Clinicaltrials.gov from January 1, 1950 to October 31, 2023. STUDY SELECTION AND DATA EXTRACTION: Relevant articles in English relating to the pharmacodynamics, pharmacokinetics, efficacy, and safety of spesolimab were included. DATA SYNTHESIS: In one phase 2 clinical trial evaluating single dose IV spesolimab for GPP flares at day 8, 54% of patients receiving spesolimab had a GPP physician global assessment (GPPGA) pustulation subscore of 0, and 43% had a GPPGA total score of 0 compared with 6% and 11% for the placebo group, respectively. Another phase 2 clinical trial assessing subcutaneous spesolimab found 23% of patients in low-dose, 29% in medium-dose, and 10% of high-dose spesolimab had flares by week 48 compared with 52% of the placebo group. Hazard ratios for time to GPP flare compared with placebo were 0.16 (P = 0.0005), 0.35 (P = 0.0057), and 0.47 (P = 0.027) for the spesolimab groups, respectively. Infection rates were similar across treatment and placebo groups, and severe adverse events such as drug reactions with eosinophilia and systemic symptom (DRESS), cholelithiasis, and breast cancer occurred with spesolimab. RELEVANCE TO PATIENT CARE AND CLINICAL PRACTICE IN COMPARISON TO EXISTING DRUGS: Spesolimab is a first-in-class IL-36 monoclonal antibody receptor antagonist approved for the treatment of acute GPP flares. It is a safe and effective therapeutic agent in preventing future GPP flares, with no current comparator trials with other GPP agents. CONCLUSION: Spesolimab is a safe and effective treatment for acute GPP flares in adults. Future clinical trials can establish safety and efficacy compared with other agents.

RESUMEN

INTRODUCTION: Psoriasis is an immune-mediated inflammatory skin disease. First-line topical treatments include steroids, calcineurin inhibitors, vitamin D analogs, and anthralin. Recently, novel topical therapeutics like tapinarof and roflumilast have emerged with unique anti-inflammatory mechanisms and promising efficacy profiles. MATERIALS AND METHODS: This review utilized PubMed, SCOPUS, and Web of Science databases to identify recent studies on tapinarof and roflumilast. Criteria focused on efficacy, safety profiles, and therapeutic roles in psoriasis treatment. RESULTS: Four primary literature articles were identified for tapinarof and five for roflumilast. Both drugs demonstrated strong efficacy with minimal adverse events in treating mild-to-moderate plaque psoriasis. Tapinarof showed more frequent but mild adverse effects, while roflumilast had less frequent but more severe side effects. DISCUSSION: Tapinarof and roflumilast offer once-daily dosing and successful treatment in restricted areas, potentially enhancing patient adherence. Cost remains a limiting factor, necessitating future comparative studies to evaluate the efficacy, safety, and cost-effectiveness between the two drugs. CONCLUSION: Tapinarof and roflumilast present promising topical treatments for psoriasis, showing efficacy and manageable safety profiles. Further research is crucial to fully elucidate their comparative benefits and drawbacks in clinical practice.

RESUMEN

BACKGROUND: Dermal fillers have emerged as a popular non-surgical solution for facial rejuvenation and enhancement. Apart from botulinum toxin injections, they are the most common non-surgical procedure performed in the US. Line-field optical coherence tomography (LC-OCT; deepLive system Damae Medical, France) represents one of the most recent developments in non-invasive skin imaging technologies. MATERIALS AND METHODS: We performed LC-OCT image acquisition on six patients that were treated with hyaluronic acid (HA) dermal fillers in various locations on the face. The images were acquired before the application of the fillers (T0), immediately after (T1), and at a 6- to 8-week (T2) follow-up visit. RESULTS: At T0, we were able to appreciate a normal-appearing epidermis, dermoepithelial junction, and dermis. At T1, the intradermal filler deposits appeared as homogeneously hyporeflective areas, clearly discernible from surrounding vessels and other structures. At T2, the deposits were distinguishable as hyporeflective areas, although they were diminished in size compared to T1. On enface view, collagen fibers had increased thickness and were more homogeneously organized and hyperreflective. CONCLUSIONS: We established the usefulness of LC-OCT in the non-invasive evaluation of dermal HA fillers to visualize both short-term and medium-term effects. LC-OCT may be a valuable tool in evaluating the precise location of filler placement and follow-up of resulting in vivo changes.

RESUMEN

BACKGROUND: Hydradermabrasion, also known as "HydraFacial," is an exfoliative cosmetic procedure for skin rejuvenation that has gained popularity. Despite its increasing popularity, clinical studies validating its efficacy with non-invasive assessment of histological changes to the skin, are scarce. In this study, we used Line-Field Confocal Optical Coherence Tomography (LC-OCT), an optical imaging device, to non-invasively visualize microscopic changes to skin anatomy after hydradermabrasion treatment. MATERIALS/METHODS: Eight volunteers (Fitzpatrick skin types II-V) were recruited for this study. Images, using LC-OCT (DeepLive, DAMAE medical) were obtained before and after hydradermabrasion and at 2 weeks post-treatment. A commercially available hydradermabrasion device was utilized to perform the dermabrasion. RESULTS: In the epidermis, initially, a decrease in the average thickness of the stratum corneum, from 9.42 to 6.67 µm was visualized in LC-OCT images after hydradermabrasion. However, at 2 weeks of follow-up, the average stratum corneum thickness was 9.75 µm, resulting in an overall increase in the average thickness after treatment. Improved homogenization of the stratum corneum and decreased number of undulations in the epidermis post-treatment were also visualized. In all the subjects, the superficial dermis appeared stretched, which returned to baseline by the 2-week follow-up. At the 2-week follow-up, there were no visible differences in the quality and quantity of collagen fibers in the dermis. CONCLUSION: In our study, LC-OCT images of the epidermis and dermis demonstrated microscopic features of skin rejuvenation when treated with hydradermabrasion. Thus, not only highlighting the efficacy of hydradermabrasion but also the potential of LC-OCT to serve as a tool for visualizing the microscopic effects of cosmetic procedures on skin anatomy.

RESUMEN

BACKGROUND: Vivascope 2500 ex vivo confocal microscopy (EVCM) is an emerging optical imaging device that allows nuclear level resolution of freshly excised tissues. EVCM provides, rapid real-time pathological examination in many subspecialties of pathology including skin, prostate, breast, liver, etc. In contrast to traditional time-consuming frozen sectioning and histological analysis. AIMS: To evaluate the current state of EVCM utilization. MATERIALS AND METHODS: This study highlights the advantages, limitations, and prospects of EVCM in skin pathology. RESULTS: Our findings demonstrate that EVCM is a promising adjunctive tool to assess margins in Mohs surgery and to provide rapid, accurate diagnosis of cutaneous tumors, infectious and inflammatory diseases. CONCLUSION: EVCM is a revolutionary device that can be used as an adjunct to paraffin-fixed, hematoxylin and eosin-stained slides and frozen sectioning. Additional refinements are required before EVCM can be used as an alternative to frozen sectioning or traditional tissue processing.

RESUMEN

BACKGROUND: Tinea pedis is the most common form of dermatophytosis resulting in interdigital infections. All of Us (AoU) is a National Institute of Health initiative with an emphasis on patient populations traditionally underrepresented in biomedical research. OBJECTIVES: Our objective was to evaluate the burden of tinea pedis in underrepresented groups in the United States, utilising the novel AoU research program. METHODS: We analysed AoU Registered Tier dataset version 5, which includes data collected between 30 May, 2017, and 1 April, 2021. We conducted a cross-sectional analysis linking survey and electronic health record (EHR) data to estimate the prevalence of tinea pedis in underrepresented groups. RESULTS: All of Us data release includes 329,038 participants. Of these, 251,597 (76.5%) had electronic health record data and 6932 had tinea pedis (overall prevalence, 2.76%; 95% CI, 2.69-2.82). Multivariate analyses revealed that compared with White participants, Black and Hispanic participants had a higher adjusted odds of tinea pedis (OR, 1.29; 95% CI, 1.20-1.38 and OR, 1.38; 95% CI, 1.28-1.48, respectively). Higher adjusted odds of tinea pedis were observed in underrepresented groups defined by: age > =75 years (OR, 1.45; 95% CI, 1.33-1.57), LGBTQ status (OR, 1.17; 95% CI, 1.09-1.27), less than a high school education (OR, 1.22; 95% CI, 1.11-1.34), income <$35,000 (OR, 1.09; 95% CI, 1.02-1.16) and physical disability (OR, 1.56; 95% CI, 1.08-1.24). CONCLUSIONS: Our findings are consistent with overall age, and gender-specific prevalence estimates from prior epidemiologic studies, validating the scientific consistency of the new AoU database. Additionally, there may be an increased burden of tinea pedis among Black and Hispanic individuals.

RESUMEN

Androgenetic alopecia (AGA) is the most common cause of hair loss in men and has limited treatment options. Minoxidil is a common therapeutic option for AGA patients because of its availability. Platelet-rich plasma (PRP) therapy is a newer option in AGA management with promising results that may be suitable for some patients. Despite a great prevalence of AGA outside the United States and Europe, there remains limited studies on the efficacy of PRP for AGA treatment. Our study's objective was to compare the efficacy of PRP and minoxidil therapy for the treatment of AGA in a Pakistani population. 72 patients were included in this randomized control trial and were either treated with PRP or topical minoxidil. After 12 weeks of treatment, the hair pull test was performed and extracted hair was counted. We report a 91.7% negative hair pull rate in the PRP treatment group which was significantly greater than the 69.4% negative hair pull rate in the minoxidil-treated group. Our study suggests that PRP therapy demonstrates a higher efficacy compared to minoxidil for treating AGA, especially in our patient demographic. These results have the opportunity to improve patient compliance and overall satisfaction while offering an improved option in patients unsatisfied with topical minoxidil.  Citation: Shah R, Asim M, Ouellette S, et al.

RESUMEN

Porokeratosis is a rare group of acquired or hereditary dermatoses characterized by linear or annular plaques with a keratotic border. DSAP is the most common porokeratosis, and lesions range from asymptomatic to pruritic circular pink to brown macules, papules, or plaques surrounded by a raised border. DSAP carries about 7.5-10% risk of malignant transformation to SCC or BCC. While in the past DSAP has been widely treated with topical diclofenac, ingenol mebutate, topical vitamin D analog, 5-fluorouracil, imiquimod, photodynamic therapy, retinoids, cryotherapy, and laser therapy, these therapies have shown limited efficacy and have caused adverse effects including inflammatory reactions, hyperpigmentation, pain, and erythema. Recently, a formulation of topical statin and cholesterol has surfaced as a new and promising treatment for DSAP which has shown clinical improvement with a tolerable adverse effect profile when compared to the current therapies. Of the 8 case studies with a total of 20 patients with DSAP, 90% (18/20) reported clinical improvement with various forms of topical statin therapy. While promising, larger randomized controlled trials are needed to evaluate the long-term use of topical statins for DSAP. J Drugs Dermatol. 2023;22(10):     doi:10.36849/JDD.7540.

RESUMEN

BACKGROUND: Firstly, confirm penetration of the skin's most exclusive layer, the stratum corneum (SC), by commercially available microneedle patches using reflectance confocal microscopy (RCM). Secondly, determine the deepest layer of the skin penetrated by the microneedle patches. MATERIALS AND METHODS: In this proof-of-concept study, 3 commercially available dissolving microneedle patches with different active ingredients were included in this study. RCM images of the cheek were taken prior to patch application at 4 different layers of the skin: stratum corneum, stratum spinosum-granulosum, dermal-epidermal junction, and papillary dermis. Patches were then applied to the cheeks of participants according to manufacturer guidelines. Immediately after removal, the same area and layers were imaged using RCM and assessed for features of penetration. RESULTS: Micropores were visualized in RCM images of skin layers post-application of all patches when compared with imaging before application. Characteristics of penetration included uniformly sized, shaped, and spaced well-defined circular areas, which are the created micropores. All 3 patches penetrated the SC to the level of the papillary dermis. CONCLUSION: This study confirms that the dissolving microneedle patches penetrate the most exclusive layer of the skin, the SC, down to the level of the papillary dermis as visualized through RCM. Confirming penetration with RCM shows the potential of these patches to be used for medication transmission. While future studies are needed to assess the efficacy of microneedle patches applied for their advertised skin conditions, confirming the penetration of the microneedle technology through RCM is a significant first step in this process.

RESUMEN

Recently, treatment outcomes in patients with toenail onychomycosis have improved considerably due to more effective oral antifungal medications such as terbinafine and itraconazole. These medications can either be used continuously for several weeks at a lower dose or intermittently (pulsed) at a higher dose. Previous literature comparing pulse and continuous therapy has generated mixed results.  Our study aims to compare the efficacy, in terms of clinical cure rate, of continuous vs pulse dose terbinafine regimens for toenail onychomycosis. Sixty patients with onychomycosis of Fitzpatrick skin types IV to VI, between 15 and 65 years of age, were divided into a continuous treatment group receiving 250 mg terbinafine once daily for 12 weeks and a pulse treatment group receiving 250 mg twice daily terbinafine for 1 week repeated every 4 weeks for 12 weeks. Each patient was followed up at weeks 4, 8, and 12.  Efficacy of the continuous treatment group was significantly greater at 76.67% compared with 26.67% in the pulse treatment group. Thus, we conclude that the clinical cure rate of a continuous dose regimen of terbinafine is a superior treatment option for toenail onychomycosis. However, we also suggest further studies including combinations of multiple agents and hybrid regimen models for the optimal onychomycosis treatment.   J Drugs Dermatol. 2023;22(10):     doi:10.36849/JDD.7323R1.

RESUMEN

BACKGROUND: Oral propranolol is considered the first line therapy in the treatment of infantile hemangiomas (IHs). However, there are considerable side effects due to its ability to penetrate the blood brain barrier. Alternatively, topical timolol, a non-selective beta blocker, has resulted in fewer side effects and is 4–10 times more potent in comparison to oral propranolol. This study evaluates the efficacy of 0.5% timolol maleate hydrogel for the treatment of IH. METHODS: This study was conducted via a quasi-experimental design from October 30, 2020 – April 29, 2021, at the Department of Dermatology Benazir Bhutto Hospital, Rawalpindi. 145 infants between 1–12 months in age diagnosed with superficial cutaneous hemangiomas were included in the study with a male to female ratio of 2.4:1. A thin layer of timolol maleate 0.5% hydrogel was applied to the entire surface of the patient’s IH three times daily. Digital photographs and measurements of the hemangiomas were taken at one-month intervals for a maximum of 6 months. RESULTS: The age range in this study was from 1–12 months with a mean age of 6.10 ± 2.52 months. The majority of the patients 89 (61.4%) were between 1–6 months of age. Of the 145 patients, 89 (61.4%) showed an excellent response, 44 (30.3%) showed a good response, and 12 (8.3%) showed no response to the topical 0.5% timolol maleate hydrogel treatment. CONCLUSION: The use of topical 0.5% timolol maleate hydrogel is a promising therapeutic option for the treatment of superficial IHs. Anwar F, Mahmood E, Sharif S, et al.

RESUMEN

PURPOSE: A rise in market demand for anti-aging skin care products has resulted in a proliferation of cosmeceuticals, including products that contain vitamin C. Many topicals containing vitamin C claim to reduce the appearance of wrinkles. However, these claims have not been systematically evaluated. METHODS: A systematic review of literature published between January 2015 and September 2022 was performed per PRISMA guidelines. Scopus, Web of Science, and PubMed were queried for records relevant using the following Medical Subject Heading (MeSH) terms: “Topical Vitamin C OR Ascorbic acid”, “Vitamin C efficacy”, “dermatology”, “cosmetology”, and “skin anti-aging”. Variables of interest included: study type, study location, study duration, sample size, patient description, type and ingredients of the topical formulation, outcome measurement, results, and adverse events. RESULTS: After deduplication, consideration of inclusion and exclusion criteria, and title/abstract screening, 5,428 initial records were reduced to 7 articles, including 4 meeting Level IB criteria, one meeting Level IIA criteria, and 2 meeting Level IIB criteria. Methods for assessing clinical improvements included global photodamage score, skin topography assessment, reflectance confocal microscopy (RCM) skin analysis, Dynamical Atlas, and participant self-assessment.  Conclusions: While 4 of the 7 studies met Level IB evidence, further high-quality, prospective, and comparative studies are indicated to better elucidate the role of topical vitamin C in wrinkle reduction. All the studies used vitamin C in combination with other ingredients or therapeutic mechanisms, thereby complicating any specific conclusions regarding the efficacy of vitamin C. Citation: Sanabria B, Berger LE, Mohd H, et al.

RESUMEN

Multicentric reticulohistiocytosis (MRH) is an insidious-onset, non-Langerhans-cell histiocytosis (NLCH) affecting the joints and skin. Early diagnosis is important to prevent destructive arthritis and disease-related complications. Reflectance confocal microscopy (RCM) is a technique that allows the visualization of the epidermis and superficial dermis noninvasively on a horizontal plane with quasi-histologic images of the skin. RCM features of NLCH including Rosai-Dorfman disease, adult xanthogranuloma (AXG), and juvenile xanthogranuloma (JXG) have been reported. However, RCM features of MRH have not been described previously. Here we present the RCM features of a case of MRH with dermoscopic and histopathologic features.

RESUMEN

Professional peeling using chemicals (chemical peeling) is a popular non-surgical procedure commonly used for the treatment for photoaging, pigmentary disorders, scarring, fine lines, and wrinkles. The objective of our case study was to elucidate the mechanism of action of professional peels/peeling. For proof-of-concept, we used a commercial blended peel containing trichloroacetic acid and lactic acid. The facial peeling was performed by a physician on four subjects. These subjects were followed over time in the clinic to take clinical pictures and monitor surface and anatomical changes in inflammation, melanin, and collagen at regular intervals post-peel (5 min, 48 h, and day 9). Dermoscope and Vivascope® were used to image surface and subsurface anatomical changes, respectively, and ConfoScan® was used to quantify aforementioned anatomical changes. Based on Vivascope and ConfoScan analysis, we could see clear visual clinical evidence of controlled injury-healing mechanism of peel's action: immediate but transient onset of inflammation within 5 min (indicate injury response by skin), followed by melanin redistribution evident at 48 h (indicate activation of skin's defense system), and remodeled fibrous collagen network without any inflammatory cells on day 9 (healing response). To our knowledge, this is the first ever clinical study to deconvolute the mysterious mechanism of action of peels, in-vivo.

RESUMEN

Dermatofibrosarcoma protuberans (DFSP) is an overall rare malignancy yet is one of the most common cutaneous sarcomas. The diagnosis of DFSP is typically made following histopathologic examination of the lesion, classically revealing a storiform pattern of spindle cells with elongated nuclei infiltrating the dermis and subcutis. Surgical excision is the standard treatment. Local recurrence is estimated to occur in 20-50% of cases, thus frequent postsurgical monitoring is required. Noninvasive imaging modalities offer a potential alternative to multiple repeat biopsies. We report the first case where reflectance confocal microscopy accompanied clinical examination in monitoring for DFSP recurrence postsurgical excision.

RESUMEN

BACKGROUND: Psoriasis is a chronic, inflammatory skin condition that is growing in prevalence globally. Routinely available options to assess psoriasis severity and progression are limited. More options are needed to monitor disease progression as therapeutic management is based on disease severity. OBJECTIVES: This study evaluates the usage of complete blood count components (CBC) including platelet count, mean platelet volume (MPV), and red cell distribution width (RDW) as hematological markers for assessing psoriasis severity. MATERIALS AND METHODS: In this cross-sectional study of 120 patients with psoriasis, disease severity was assessed using the PASI score followed by a blood draw to determine whether correlations existed between each marker and PASI score. RESULTS: A significant, positive correlation was found between total platelet count and PASI while no such correlation was found in MPV and RDW. When stratifying for age, duration of disease, sex, and body parts involved, we found intriguing relationships and offer potential explanations for their occurrence. CONCLUSION: Our findings suggest that hematological parameters MPV, platelet count, and RDW found in the CBC are useful in identifying psoriasis severity to some extent. We foresee the use of RDW, MPV, and platelet count biomarkers as a complement to the PASI score in assessing severity for psoriasis patients, while also as a gauge for likelihood of developing comorbidities such as cardiovascular disease.

RESUMEN

Oral tranexamic acid (TXA) is a relatively new treatment option for melasma. It is thought to reduce hyperpigmentation through inhibition of the plasminogen/plasmin pathway with resulting decreases in epidermal melanocyte tyrosinase activity, inflammatory mediators, dermal neovascularization, and mast cell numbers.

RESUMEN

Malignant melanoma is one of the most aggressive solid tumors but has low morbidity if treated at an early stage. Over the past decade, the advent of targeted therapy and immunotherapy have productively enriched the treatment options for advanced melanomas and further improved the prognosis. The treatment of melanoma is a rapidly evolving field. In patients with sentinel lymph node (SLN)-positive (SLN+) melanoma, the role of complete lymph node dissection (CLND) is still a matter of debate. Sentinel lymph node biopsy (SLNB) is a staging procedure for melanoma that is routinely offered to patients with tumor thickness ≥1 mm or ≥0.8 mm with additional risk factors and is widely accepted as an important diagnostic and prognostic tool, since SLN+ patients can receive adjuvant targeted treatment or immunotherapy. Currently, the role of CLND has largely been replaced by often recommended adjuvant therapies since their approval. This article provides an overview of sentinel lymph-node surgery in cutaneous melanoma. J Drugs Dermatol. 2022;21(5):510-516. doi:10.36849/JDD.6198.

RESUMEN

Congenital melanocytic naevi are hamartomas of the neuroectoderm caused by genetic mosaicism. Congenital melanocytic naevi are seen in 1-6% of all live births and commonly classified based on the projected size in adults. Congenital melanocytic naevi appear in different colours, shapes, and sizes, and occasionally present with complications. In this review, we sought to evaluate congenital melanocytic naevi, their clinical, dermatoscopic, and reflectance confocal microscopic features, behavioural pattern over time, new trends in classification, underlying genetic factors and their influence on clinical manifestations and management, associated risks, complications, magnetic resonance imaging findings and their management in the light of recent literature.
