New Topical Therapies for Psoriasis.
Lé, AM, Torres, T
American journal of clinical dermatology. 2022;(1):13-24
Abstract
Psoriasis is a chronic immune-mediated skin disease with a significant impact on patients' quality of life. Mild-to-moderate forms of the disease usually require long-term topical treatment, but prolonged use of corticosteroids and vitamin D analogues is limited by adverse effects. With further understanding of psoriasis pathogenesis, new molecules are emerging aiming to fulfil these clinical needs. Tapinarof, an aryl hydrocarbon receptor modulator, has completed a phase III study and demonstrated good efficacy results, even in long treatment courses, with a favourable safety profile. It additionally appears to have a promising remitting effect as patients presented with an average relapsing time of over 3 months. Roflumilast, a phosphodiesterase type 4 inhibitor, also underwent a phase III study with significant lesion improvement and notable pruritus management, and with no reported side effects. Roflumilast was evaluated as an option for intertriginous areas with good outcomes in a small sample, but larger trials are required. The Janus kinase-signal transducer and activator of transcription pathway has been targeted in recent clinical investigations with promising options, currently with brepocitinib pending phase IIb results. Ongoing preclinical studies involving interleukin-2 inhibition, RNA modulators and amygdalin analogues may lead to forthcoming clinical trials. New topical drugs are successfully emerging and future research comparing them to classical options will dictate their clinical role in the treatment of psoriasis.

Erosive pustular dermatosis of the scalp: causes and treatments.
Karanfilian, KM, Wassef, C
International journal of dermatology. 2021;(1):25-32
Abstract
Erosive pustular dermatosis of the scalp is a rare condition which primarily affects older women after local trauma and has historically been treated with topical steroids. As it is a rare entity and resembles other dermatologic conditions, it may easily be misdiagnosed. Identifying the causes and evaluating the efficacy of treatments of erosive pustular dermatosis of the scalp (EPDS) is of great importance to both avoid misdiagnosis and ensure optimal treatment of this rare condition. There are numerous causes. In addition to surgeries and physical injuries, topical and procedural treatments for actinic keratoses and androgenetic alopecia can trigger the development of lesions. There are also documented associations with several autoimmune and systemic conditions. Besides corticosteroids, topical tacrolimus and photodynamic therapy were the most commonly used treatments for EPDS. They were effective with few recurrences and adverse effects. Other successful treatment options were topical dapsone, silicone gels, calcipotriol, acitretin, and isotretinoin. Oral dapsone can be used in cases of disseminated disease. Zinc sulfate should be considered with low-serum zinc levels. While cyclosporine was effective, there were adverse effects that may limit its use. It is important for dermatologists to be aware of the wide array of potential causes of erosive pustular dermatosis and include it on their differential. Additionally, although high-potency topical steroids have been historically used as the first-line treatment, there are many other effective treatments that may avoid recurrence and skin atrophy, particularly in the elderly population.

Baldwin, H, Alexis, AF, Andriessen, A, Berson, DS, Farris, P, Harper, J, Lain, E, Marchbein, S, Stein Gold, L, Tan, J
Journal of drugs in dermatology : JDD. 2021;(4):384-392
Abstract
BACKGROUND Rosacea, an inflammatory skin disease that leads to an impaired skin barrier function commonly involves the face. Symptoms of rosacea can be bothersome and include pain, stinging, burning, itching, and facial flushing. This review explored skin barrier impairment in rosacea and reduced symptomatology when using over the counter (OTC) skincare products. METHODS Nine dermatologists (the panel) completed a survey on OTC products they recommend for rosacea. The survey results were summarized, presented, and discussed during the online meeting, together with the results of a literature review. The outcome of these discussions, coupled with the panel's expert opinion and experience, is shown in the current review. RESULTS Addressing barrier dysfunction by use of moisturizer and cleanser formulations that restore skin hydration, normalize skin pH, restore the microbiome, and skin lipids can assist in improving rosacea signs and symptoms. The panel's consensus was that in addition to the use of prescription medications, skincare recommendations are a crucial part of successful rosacea therapy. In addition to occlusives and humectants, barrier restoring ingredients such as ceramides, hyaluronic acid, and niacinamide were considered beneficial. Equally important was the absence of potentially irritating substances. CONCLUSIONS The use of OTC products can improve rosacea symptomatology and signs. As adjuncts, these products are recommended before and during prescription therapy and as part of a maintenance regimen.

Myositis Induced by Isotretinoin: A Case Report and Literature Review.
Rivillas, JA, Santos Andrade, VA, Hormaza-Jaramillo, AA
The American journal of case reports. 2020;:e917801
Abstract
BACKGROUND Retinoid-induced myositis is a rare condition encountered in clinical practice. Its occurrence implies a diagnostic challenge due to the multiple causes associated with myopathic syndromes. The most common clinical presentation is generalized affection. Focal myositis is even less frequent and easily misdiagnosed as muscular disease of other etiology. CASE REPORT We describe a case of 45-year-old male with a history of nephrolithiasis and rosacea diagnosed by dermatology, who was management with isotretinoin 1 mg/kg per day in 2 doses with clinical improvement. Later, he presents muscle pain in the upper limbs with marked functional limitation associated by choluria, without muscular pains in other location; he had no history of using another medication. At his physical examination, vital signs were normal, with edema and pain in the bilateral bicipital region associated with limitation for flexion-extension of shoulders and elbows and high levels of creatine phosphokinase (CPK). He was transferred to the intensive care unit where he received fluid therapy because of the high risk of deterioration of renal function, very high CPK levels, and a history of obstructive uropathy. One year after this hospitalization, the cutaneous symptoms worsened and the patient voluntarily restarted isotretinoin and 5 months later he presented again with the same symptoms of the first episode. CONCLUSIONS Drug-induced myositis should be taken into consideration in the differential diagnosis of myopathic syndromes. Retinoids have the potential to cause varying degrees of myositis and their rapid identification could prevent major complications.

Pharmacological treatments for cutaneous manifestations of inherited ichthyoses.
Cortés, H, Del Prado-Audelo, ML, Urbán-Morlán, Z, Alcalá-Alcalá, S, González-Torres, M, Reyes-Hernández, OD, González-Del Carmen, M, Leyva-Gómez, G
Archives of dermatological research. 2020;(4):237-248
Abstract
Inherited ichthyoses are a group of etiologically heterogeneous diseases that affect the function of the skin and that are classified as syndromic and non-syndromic entities. Irrespective of the type, all these disorders are generally produced by mutations in genes involved in a variety of cellular functions in the skin. These mutations lead to disruption of the stratum corneum and impairment of the skin barrier, producing clinical features such as hyperkeratosis, skin scaling, erythema, fissures, pruritus, inflammation, and skin pain. Despite advances in the knowledge of the pathogenesis of ichthyoses, there is, to our knowledge, no definitive cure for skin manifestations, and current treatments consist of moisturizers, emollients, and keratolytic agents. In this respect, the development of new formulations based on nanotechnology could be useful to enhance their therapeutic effectiveness. In this article, we provide a comprehensive description of pharmacological treatments for cutaneous manifestations in patients with inherited ichthyosis and discuss novel approaches with therapeutic potential for this purpose. Moreover, we offer an overview of toxicity concerns related to these treatments.

Calcipotriol/betamethasone dipropionate formulations for psoriasis: an overview of the options and efficacy data.
Megna, M, Cinelli, E, Camela, E, Fabbrocini, G
Expert review of clinical immunology. 2020;(6):599-620
Abstract
INTRODUCTION Psoriasis is a very common chronic inflammatory skin disease affecting up to 3% of the general population with 75% of the psoriasis subjects being affected by a mild form of disease. Hence, topical therapy is the most frequent employed treatment in psoriasis also because it can be easily combined with systemic therapy. In this context, calcipotriol/betamethasone dipropionate (Cal/BD) fixed-dose association represents the first-line treatment due to its efficacy and once-daily application. Different Cal/BD formulations, such as ointment, gel (topical suspension), and aerosol foam, are approved by US Food and Drug Administration. AREAS COVERED For this review, relevant English literature (trials, real-life studies, case series, and reviews) regarding Cal/BD different formulations efficacy in psoriasis was searched for through to 28 January 2020. The following database were consulted: PubMed, Embase, the Cochrane Library, Google Scholar, EBSCO, and clinicaltrials.gov. EXPERT OPINION Cal/BD formulations are efficacious treatment for psoriasis. Cal/BD aerosol foam shows a higher efficacy compared to Cal/BD ointment or gel formulations, appearing as a game-changer in psoriasis therapy not only for mild disease but also for moderate psoriasis as well as in selected severe cases in combination with systemic treatments.

Management of Ichthyosis: A Brief Review.
Limmer, AL, Nwannunu, CE, Patel, RR, Mui, UN, Tyring, SK
Skin therapy letter. 2020;(1):5-7
Abstract
The ichthyoses, also termed the disorders of keratinization, are a heterogenous group of skin diseases in which a distinctive horny layer arises secondary to excessive transepidermal water loss. Although occasionally acquired, the majority of ichthyoses are inherited and can be pinpointed to characteristic genetic mutations. Management depends on disease severity and includes topical agents and lifestyle modifications with or without oral retinoids. Genetic counseling is also an important consideration. This review aims to highlight advances in our understanding of disease pathogenesis as well as the holistic approach necessary to adequately manage ichthyosis patients.

Psoriasis and Treatment: Past, Present and Future Aspects.
Reid, C, Griffiths, CEM
Acta dermato-venereologica. 2020;(3):adv00032
Abstract
The management of psoriasis has evolved considerably over the past 100 years. This has occurred in parallel with our understanding of the pathogenesis of this common, complex and enigmatic disease. It should be celebrated as an outstanding example of successful translational research. With precise targeting of immune pathways for the treatment of psoriasis with new biologics and small molecules has come the realisation that the most effective approach to patient management is a holistic one which encompasses the biopsychosocial nature of the disease. This involves a stratified medicine approach to identifying the best drug for an individual allied to patient education, screening for comorbidity, and regular review as both the clinical presentation and the patient's needs will change over time. Al-though there is not yet a cure for psoriasis - the whole person, systems approach to patient management, that is in part dependent on early intervention, should help to ensure an optimal outcome.

Use of Topical and Systemic Retinoids in Solid Organ Transplant Recipients: Update and Review of the Current Literature.
Herold, M, Good, AJ, Nielson, CB, Longo, MI
Dermatologic surgery : official publication for American Society for Dermatologic Surgery [et al.]. 2019;(12):1442-1449
Abstract
BACKGROUND Solid organ transplant recipients (SOTRs) are at an increased risk of epithelial malignancies, mainly squamous cell carcinoma, and its precursor lesions such as actinic keratoses, warts, and porokeratosis, which may respond to retinoid therapy. OBJECTIVE To review the published evidence on the efficacy and safety of topical and systemic retinoids for the treatment and prophylaxis of malignant and premalignant conditions that mostly afflict SOTRs. MATERIALS AND METHODS Systematic review of the literature to summarize the level of evidence and grade of recommendation for retinoid therapy with emphasis in the SOTR population. RESULTS Acitretin has the highest strength of recommendation (Grade A) for prophylaxis of nonmelanoma skin cancer (NMSC) and treatment and prophylaxis of actinic keratoses in SOTR. In nonimmunosuppressed patients, acitretin and isotretinoin have a Grade B recommendation for treatment of recalcitrant warts. Topical retinoids have not shown efficacy in preventing NMSC in immunocompetent patients. CONCLUSION Retinoids constitute a highly efficacious alternative for the management of the most common conditions that affect SOTRs. Acitretin has the most robust evidence for chemoprophylaxis in SOTRs. Knowledge about the specific indications and expected side effects of topical and systemic retinoids may help optimize their therapeutic potential.
