RESUMO
BACKGROUND: Management of hidradenitis suppurativa (HS) is challenging since no single treatment provides consistently effective results, leaving patients with frequent relapses. Dapsone combines anti-microbial and anti-inflammatory properties that address aspects of HS pathogenesis. Few studies have evaluated the efficacy of oral dapsone on HS, especially in severe disease. OBJECTIVE: This study aims to evaluate the clinical outcomes of patients with moderate-to-severe HS treated with dapsone. METHODS: This retrospective chart review evaluated HS patients treated with oral dapsone over the past 10 years at one center. Treatment outcomes were classified based on Hurley staging, physician exam, and symptom progression. Adverse effects and concomitant treatment with dapsone were reviewed. RESULTS: Nineteen (19) patients with moderate-to-severe (Hurley Stage II-III) HS treated with oral dapsone were identified. Within 1-3 months, on dosages of dapsone varying from 25-100 mg/day, 3 patients (15.8%) had a clinically significant improvement in symptoms, 10 patients (52.6%) had a slight improvement, and 6 patients (31.6%) had no change in disease state; no patients deteriorated. The majority who improved were also on other medications, most commonly adalimumab. 4 patients experienced adverse effects, with nausea being most common; otherwise, dapsone was well-tolerated. CONCLUSIONS: Dapsone may have some efficacy for moderate-to-severe HS and seems well-tolerated. J Drugs Dermatol. 2023;22(11):e12-e16 doi:10.36849/JDD.4936e.

ABSTRACT: Levamisole, an anthelmintic and immunomodulatory drug, was withdrawn from the US market in 1999 due to adverse effects, including agranulocytosis and vasculitis. In recent years, levamisole has been used as a common cocaine adulterant, and its use has led to an autoimmune syndrome characterized by an antineutrophil cytoplasmic antibody-associated vasculitis presenting with necrotic retiform purpura on the face and extremities. We present a case of recurrent levamisole-induced vasculitis initially misdiagnosed as systemic lupus erythematosus to highlight this easily misdiagnosed entity and to demonstrate re-exposure leading to recurrent vasculitis with more extensive clinical manifestations.

INTRODUCTION: Psoriasis is a common, chronic inflammatory skin condition that affects 2-3% of the US population and represents a large psychosocial burden for patients. Over the last decade, highly effective targeted therapies for psoriasis have been developed - namely, those targeting interleukin (IL)-17 and IL-23. The success of biologic agents targeting IL-17 and IL-23 underscores the importance of the IL-23/T helper (Th)17 cell axis in psoriasis pathogenesis. Oral small molecule drugs - such as Janus kinase (JAK) inhibitors, tyrosine kinase 2 (TYK2) inhibitors, and fumaric acid esters (FAEs) - are also being investigated for the treatment of psoriasis. AREAS COVERED: This article reviews systemic biologic and oral small molecule drugs currently undergoing clinical trials for the treatment of plaque psoriasis. EXPERT OPINION: Many patients with psoriasis have mild disease, and many with mild disease do not seek medical care for their condition. Many patients with mild disease could be adequately treated with topical treatments and phototherapy; however, adherence and feasibility have often been an issue with these treatment types. There seems to be limited room for development of novel biologics, as the existing ones are extraordinarily safe, effective, and convenient with few injections. Patients would prefer a safe, effective oral treatment; however, JAK inhibitors seem unlikely to fill this role completely.

Objective: To review phase II and III clinical trial data to evaluate the efficacy and safety of the halobetasol propionate/tazarotene (HP/TAZ) combination lotion (Duobrii), a medication approved by the Food and Drug Administration in April 2019 for adults with plaque psoriasis. Data Sources: A systematic search (January 2005 to July 2019) of MEDLINE (PubMed) and EMBASE databases was performed using the terms halobetasol, tazarotene, halobetasol/tazarotene, Duobrii, and IDP-118. Study Selection and Data Extraction: Relevant English-language articles reporting on phase II and phase III clinical trials were included. Data from the individual trials were extracted independently and then cross-checked to ensure accuracy. Data Synthesis: HP/TAZ was safe and efficacious compared with HP alone, TAZ alone, or vehicle. More patients achieved treatment success, described as a ≥2-grade improvement on Investigator Global Assessment Scale, over 8 weeks of treatment and at the 4-week follow-up after treatment cessation. The most common adverse events were dermatitis, pain, and pruritus, which occurred more often in the TAZ groups compared with the HP/TAZ cohorts. Relevance to Patient Care and Clinical Practice: The once-daily HP/TAZ combination lotion simplifies psoriasis treatment and may facilitate adherence, which may improve psoriasis outcomes. Conclusions: HP/TAZ combination lotion is efficacious and safe for plaque psoriasis treatment, with more patients achieving end points and fewer side effects than in HP, TAZ, or vehicle-treated controls. Drug synergy may play a role. Importantly, patient adherence to a once-daily combinational therapy is likely to contribute to efficacy.

BACKGROUND: Self-application of topicals on the back can be challenging. OBJECTIVE: The aim was to assess topical back coverage using commercially available back applicators. MATERIALS AND METHODS: Ten subjects applied sunscreen to their back using their hands and then with 3 back applicators (large foam tip, small foam tip, roller tip). The amount of lotion used and the time it took to perform the application were recorded. The resulting distribution of sunscreen was assessed with a Wood's lamp; the area covered fluoresced less than the uncovered skin. Images were captured and then analyzed using an automated thresholding technique. RESULTS: Subjects applied more lotion when using the large foam tip (7.58 g, 95% CI 6.47-8.70 g; P < .004) and small foam tip (7.46 g, 95% CI 6.35-8.57 g; P < .006) applicators compared to hands alone (6.22 g, 95% CI 5.10-7.33 g). Application time was longer with the small foam tip applicator (113.4 s, 95% CI 96.7-130.1 s) relative to hand application (78.7 s, 95% CI 62-95.4 s) (P < .03). Coverage of the back was higher for the large foam tip (84.8%, 95% CI 78.4%-91.3%; P < .03), small foam tip (88.0%, 95% CI 81.6%-91.5%; P < .006), and roller tip (84.3%, 95% CI 77.9%-90.8%; P < .04) applicators compared to hand application (71.5%, 95% CI 65%-78%). The middle back tended to have less coverage when applying with the hands. CONCLUSIONS: Topical coverage of the back is improved with the use of applicator devices during self-application.

Drug expenditure in the United States has continued to increase unsustainably; the specialty of dermatology has been particularly affected. Resources are limited - someone has to make decisions about what treatments will be covered and how they will be reimbursed. Step therapy is a cost-control method used by insurers to encourage the use of the most cost-effective treatments before more expensive options are attempted. However, a rigid step therapy policy can be problematic when protocols are out of date, or delay necessary treatment leading to unnecessary suffering, increased morbidity, and overall cost. To address some of these concerns, the proposed Safe Step Act (S. 2546 and H.R. 2279) attempts to create a requirement that insurers provide a transparent, expeditious exceptions process for step therapy protocols. Increased flexibility in this process will allow for the unique circumstances of individual patients and improve access to expensive drugs for special cases. However, this bill may be exploited, further weakening insurers' ability to negotiate on cost. We should be cautious about measures that reduce the effectiveness of this tool, particularly if we, as a society, aim to expand access to basic care to all Americans.

BACKGROUND: Systemic methotrexate (MTX) is a useful treatment for many dermatologic conditions, however, the risk of adverse events prevents its use in patients with minimal or localized disease. Topical application of MTX may be an option to avoid the systemic adverse effects of oral MTX. OBJECTIVE: To assess what is known about the efficacy and safety of topical methotrexate. METHODS: A search on Pubmed was conducted. There were no limits on publication date. RESULTS: A total of 963 articles were discovered. Using our exclusion criteria, 916 articles were excluded; 47 articles were used for full text assessment. Topical MTX has been used primarily in psoriasis but also in mycosis fungoides, lymphomatoid papulosis, and oral precancerous lesions. Optimal delivery system and formulation for adequate penetration is still under investigation. CONCLUSION: The quality of evidence for the utility of topical methotrexate in psoriasis is good, however, for other dermatologic diseases, the quality is poor. Topical MTX with improved delivery methods may be a viable tool against certain localized dermatologic conditions for patients who do not tolerate oral MTX. Further double-blinded randomized controled studies are needed to substantiate the utility of topical methotrexate.

BACKGROUND: The novel coronavirus (COVID-19) has an affinity for almost every organ system, including the skin. This review article will compile and compare dermatology guidelines related to the dermatologic care of patients during the COVID-19 pandemic. OBJECTIVE: To review and compare the available guidelines and recommendations on use of biologics and other systemic therapies in dermatology patients. METHODS: We conducted a search for guidelines and recommendations for dermatology providers, with specific attention to the management of biologics and non-biologic systemic agents during COVID-19. International and United States-based guidelines specific to the field of dermatology and guidance for healthcare providers were used as inclusion criteria. Available registries were included as well. CONCLUSION: The guidelines stress a shared decision-making approach with risk-benefit analysis and treatment strategy modifications tailored to each unique patient case. The guidelines were all concordant with one another in highlighting the importance that patients should not discontinue their medications without first speaking with their providers.

Individuals with chronic illnesses turn to online communities to engage in asynchronous peer-to-peer exchanges to better understand and manage their disease. Messages and advice exchanged by online users with vitiligo are not well characterized. We conducted a qualitative study to explore the content exchanged by individuals with vitiligo in online forums. An interpretive research paradigm was utilized to assess public online forum content. A systematic search using the phrases online forum vitiligo support, vitiligo online message board, and vitiligo forums identified 39 relevant forums; 9 of them met inclusion criteria, with 382 total anonymous users. Major themes and subthemes included vitiligo disease management, homeopathy/home remedies, psychosocial impact, public perceptions, and camouflage/concealment.

Severe, uncontrolled atopic dermatitis (AD) persisting from childhood to adulthood can have enduring quality of life (QoL) impacts on daily functioning, academics, career, family and social life, and mental health. In addition, AD has an impact on direct and indirect healthcare resource utilization. Several studies have attempted to quantify the quality of life and direct/indirect economic burden of AD. However, these estimates may not capture the more intangible disease-related burden and associated economic burden. This was a qualitative case report that aimed to investigate the full lifetime impact of severe, uncontrolled AD on all aspects of a single patient's life. This case report emphasizes the enormous cumulative lifetime impact of severe, uncontrolled AD and where the qualitative indirect impact may not be fully captured. After obtaining consent, a patient, diagnosed with severe AD since birth, was asked close- and open-ended questions about AD history, direct and indirect healthcare resource utilization, and impact of AD on work, home, family, social life, daily functioning, and mental health over the course of her lifetime. Our patient attributed her severe, uncontrolled AD since birth to causing poor sleep quality, depression, anxiety, and difficulty with social connections and to her choosing an alternative, less physically demanding career. Early effects on sleep and school performance, along with impact on social connections, likely contribute to weaker career opportunities and further social isolation with age.
RESUMO
Pyoderma gangrenosum is a rare neutrophilic dermatosis that is commonly treated with systemic corticosteroids; however, their potent side effects may warrant tapering, and non-steroidal systemic immunosuppressants may help maintain or bolster disease clearance during weaning. Although cyclosporine is regarded as a favorable corticosteroid-sparing agent, it is associated with several side effects, such as renal toxicity and hypertension, that may limit its feasibility. Mycophenolate mofetil is a well-tolerated alternative with limited data. Institutional review board approval was obtained to review patients from a single institution who received mycophenolate mofetil for pyoderma gangrenosum between January 1, 2010, and December 31, 2019. A systematic MEDLINE (PubMed) review was performed of articles containing linked keywords: "mycophenolate mofetil" and "pyoderma gangrenosum". Patient demographics, presentation details, and treatment regimen characteristics were recorded. Fourteen of our pyoderma gangrenosum patients were treated with mycophenolate mofetil concomitantly with prednisone. Ninety-three percent of our patients achieved improvement within 12 months (mean 4.5 months), including five patients who experienced complete healing. Outcomes in literature patients were comparable; 77% either improved or maintained clearance with mycophenolate mofetil. Greater than 80% of total patients experienced healing or adequate disease control at a median dose of 2000 mg daily. The most common side effects of mycophenolate mofetil were myelosuppression and gastrointestinal upset, which were both seen in 18% of patients. Although this study is subject to publication bias, mycophenolate mofetil appears to be an efficacious and well-tolerated adjunctive therapy option for pyoderma gangrenosum.

Atopic dermatitis (AD) is a common, chronic inflammatory skin disease that oftentimes requires complex therapy. Poor adherence is a major barrier to AD treatment success. An interspecialty, virtual roundtable panel was held, through which clinical dermatologists, allergists, and behavioral and social psychologists discussed AD management and adherence. Relevant literature was reviewed, and the content of this article was organized based on the roundtable discussion. Current guidelines for AD treatment include maintenance and acute therapy for mild-to-severe AD. Therapy is often complex and requires significant patient involvement, which may contribute to poor treatment adherence. Behavioral and social psychology strategies that may help improve adherence include scheduling timely follow-up appointments, using a clearly written eczema action plan (EAP), reducing perceived treatment burden, utilizing anchoring techniques, sharing anecdotes, and rewarding children using positive reinforcement and stickers. There are multiple practical ways by which providers can improve both the management and treatment adherence of patients with AD.
RESUMO
Statins cause a spectrum of muscle-related adverse events, including autoimmune myopathies such as dermatomyositis (DM). This review aims to describe the events of statin-induced DM and amyopathic dermatomyositis (ADM) to increase awareness for practicing dermatologists about harmful interactions with the most commonly prescribed lipid-lowering medication. PubMed was searched for relevant literature related to statin-induced DM and ADM. Numerous cases of statin-induced DM have been reported in individuals with no history of DM or other autoimmune conditions. Statins also cause ADM, although this is a rare association. Because of the widespread use of statins worldwide for atherosclerotic disease prevention, it may be of benefit to practicing dermatologists and all clinicians to assess for a history of DM when prescribing statins and inquire if patients with a DM-like presentation are taking or have taken a statin medication.
