ABSTRACT

BACKGROUND: Rapid skin improvement is a key treatment goal of patients with moderate-to-severe psoriasis (PsO). OBJECTIVES: To compare the speed of clinical improvement of approved biologics on the symptoms and signs of psoriasis assessed by patients using the validated Psoriasis Symptoms and Signs Diary (PSSD) through 12 weeks. METHODS: Psoriasis Study of Health Outcomes (PSoHO) is an international, prospective, non-interventional study that compares the effectiveness of anti-interleukin (IL)-17A biologics versus other biologics, together with pairwise comparisons of ixekizumab versus five individual biologics in patients with PsO. Using the PSSD 7-day recall period, patients assessed the symptoms (itch, skin tightness, burning, stinging and pain) and signs (dryness, cracking, scaling, shedding/flaking, redness and bleeding) of their psoriasis (0-10). Symptom and sign summary scores (0-100) are derived from the average of individual scores. Percentage change in summary scores and proportion of patients with clinically meaningful improvements (CMI) in PSSD summary and individual scores are evaluated weekly. Longitudinal PSSD data are reported as observed with treatment comparisons analysed using mixed model for repeated measures (MMRM) and generalized linear mixed models (GLMM). RESULTS: Across cohorts and treatments, eligible patients (n = 1654) had comparable baseline PSSD scores. From Week 1, the anti-IL-17A cohort achieved significantly larger score improvements in PSSD summary scores and a higher proportion of patients showed CMIs compared to the other biologics cohort through 12 weeks. Lower PSSD scores were associated with a greater proportion of patients reporting their psoriasis as no longer impacting their quality-of-life (DLQI 0,1) and a high level of clinical response (PASI100). Results also indicate a relationship between an early CMI in PSSD score at Week 2 and PASI100 score at Week 12. CONCLUSIONS: Treatment with anti-IL-17A biologics, particularly ixekizumab, resulted in rapid and sustained patient-reported improvements in psoriasis symptoms and signs compared with other biologics in a real-world setting.

ABSTRACT

Coronavirus disease 2019 (COVID-19) is caused by SARS-CoV-2, a novel RNA virus that was declared a global pandemic on 11 March 2020. The efficiency of infection with SARS-CoV-2 is reflected by its rapid global spread. The SARS-CoV-2 pandemic has implications for patients with inflammatory skin diseases on systemic immunotherapy who may be at increased risk of infection or more severe infection. This position paper is a focused examination of current evidence considering the mechanisms of action of immunotherapeutic drugs in relation to immune response to SARS-CoV-2. We aim to provide practical guidance for dermatologists managing patients with inflammatory skin conditions on systemic therapies during the current pandemic and beyond. Considering the limited and rapidly evolving evidence, mechanisms of action of therapies, and current knowledge of SARS-CoV-2 infection, we propose that systemic immunotherapy can be continued, with special considerations for at risk patients or those presenting with symptoms.

ABSTRACT

Pruritus, or itch, is a common sensation that causes a person to want to scratch. It is a complex process that may negatively impact quality of life and commonly occurs with skin disorders such as atopic dermatitis and urticaria. It could also be a symptom related to an underlying disease process such as cholestasis or hyperthyroidism, or simply be caused by dry skin, especially in the cold, winter months. Therapy is often aimed at eliminating the underlying cause first, followed by the management of the itchy sensation. Treatment may include prescription and over-the-counter (OTC) medications, herbal remedies, hydrotherapy, phototherapy, and ultraviolet therapy. This overview provides information regarding the various management and treatment options for pruritus.

ABSTRACT

Atopic dermatitis (AD) is a chronically relapsing eczematous disorder of the skin that occurs in persons of all ages but is more common in children. AD is associated with other atopic diseases such as allergic rhinoconjuntivitis or bronchial asthma. Nearly 80% of children with AD eventually develop allergic rhinitis or asthma. AD can be classified as mixed (cases associated with respiratory allergies) and pure . Pure AD has intrinsic and extrinsic variants. In the extrinsic type, interleukin-4 is secreted by T-cells isolated from spontaneous lesions and skin-derived T-lymphocytes express more IL-13. Due to the different immunopathogenesis, it has been suggested that antileukotriene agents may be more successful in the treatment of the extrinsic subgroup. Leukotrienes (LTs) are a class of potent biological inflammatory mediators derived from arachidonic acid through the 5-lipoxygenase pathway. There is evidence of enhanced LT production in the pathogenesis of AD. Evidence in the literature provides a pathophysiological rationale for the use of cysLT receptor blockers in the treatment of AD. However, the exact mechanism of action of leukotriene receptor antagonists in AD is not known. In small clinical and case studies, montelukast was found to be a safe and effective alternative or steroid-sparing therapy in the management of patients with atopic dermatitis.

ABSTRACT

There are many herbal therapies available for dermatological diseases that patients have already begun to discover. Dermatologists must be educated not only in the benefits of these therapies, but must also be aware of some of the risks and adverse effects. They need information about the effects of herbal remedies in order to better serve their patients who may be using herbs to treat their dermatological conditions. This brief review summarizes some of the more common herbal therapies used by many dermatology patients for their skin diseases, and the adverse reactions and drug interactions that may occur.

ABSTRACT

Allergic contact dermatitis (ACD) is more frequent in the pediatric population and in children with atopic dermatitis (AD) than has hitherto been appreciated. Patch testing, which is mediated by different immune mechanisms than prick skin testing, is both safe and diagnostically useful for individuals with AD. It may help to identify exacerbating allergies, e.g., constituents of topical treatments in refractory AD and to formulate treatment plans that feature preventive avoidance of the offending allergens.

ABSTRACT

Atopic dermatitis (AD) is a chronic itchy, inflammatory skin disease that is extremely difficult to treat. Effective therapeutic agents are limited in number, and may have long-term toxic side-effects. Frustrated by these realities, many patients stop seeking help from conventional physicians and turn to alternative medical approaches. These can include so-called natural products, herbal products and over-the-counter (OTC) treatments. Herbs and medications share a common history, as most of our well-known medications were derived from plants. However, herbal remedies are largely unregulated. Many may have scientific merit and clinical benefit, but they are still scientifically invalid and inadequately monitored. Dermatologists need information about the effects of herbal remedies in order to better serve their patients.
