INTRODUCTION: Patients with chronic inflammatory skin diseases often suffer from sleep disturbances. However, objective data on sleep architecture, especially to evaluate potential overall influences under therapy, are lacking. PATIENTS AND METHODS: Pilot study on sleep quality changes including psoriasis and atopic dermatitis patients before and 2 weeks after intensive topical treatment. In addition to disease activity rating, patient-rated outcomes for itch severity and sleep quality and polygraphy was performed before and after topical therapy...

The close interaction between skin and clothing has become an attractive cornerstone for the development of therapeutic textiles able to alleviate skin disorders, namely those correlated to microbiota dysregulation. Skin microbiota imbalance is known in several skin diseases, including atopic dermatitis (AD), psoriasis, seborrheic dermatitis, rosacea, acne and hidradenitis suppurative (HS). Such microbiota dysregulation is usually correlated with inflammation, discomfort and pruritus. Although conventional treatments, that is, the administration of steroids and antibiotics, have shown some efficacy in treating and alleviating these symptoms, there are still disadvantages that need to be overcome...

As chronic inflammatory conditions driven by immune dysregulation are influenced by genetics and environment factors, psoriasis and atopic dermatitis (AD) have traditionally been considered to be distinct diseases characterized by different T cell responses. Psoriasis, associated with type 17 helper T (Th17)-mediated inflammation, presents as well-defined scaly plaques with minimal pruritus. AD, primarily linked to Th2-mediated inflammation, presents with poorly defined erythema, dry skin, and intense itching...

With an increasing number of patients eligible for immune checkpoint inhibitors, the incidence of immune-related adverse events (irAEs) is on the rise. Dermatologic immune-related adverse events (D-irAEs) are the most common and earliest to manifest, often with important downstream consequences for the patient. Current guidelines lack clarity in terms of diagnostic criteria for D-irAEs. The goal of this project is to better define D-irAE for the purposes of identification, diagnosis, and future study of this important group of diseases...

IMPORTANCE: There is no US Food and Drug Administration-approved treatment for pityriasis rubra pilaris (PRP), and it is common for patients to fail to experience improvement with several systemic options. Involvement of interleukin (IL) 23 suggests a potential therapeutic target.

Introduction : Psoriasis, a chronic inflammatory skin disease, affects 2-10% of the population globally. Bimekizumab (BMK), a monoclonal antibody targeting IL-17, is a dual inhibitor of IL17 A and F that has shown efficacy in treating moderate to severe plaque psoriasis. This real-world evidence (RWE) study aims to assess BMK's efficiency and safety in naïve and refractory patients. Material and methods: A retrospective analysis of a multicenter observational study included 22 patients treated with BMK from April 2023 to February 2023 in five Andalusian hospitals...

Scalp psoriasis is a common manifestation of psoriasis that significantly impacts a patient's quality of life. About 80% of cases of psoriasis involve the scalp, making it the most frequently affected area of the body. The treatment of scalp psoriasis is particularly crucial because of its hard-to-treat nature and substantial adverse impacts on overall well-being. Along with the physical symptoms of discomfort and itching, psoriasis, especially when it affects the scalp, can cause severe psychological damage...

Data on switching between agents in patients with atopic dermatitis (AD) are scarce (1-3). We report the case of a patient with severe AD and inadequate response to upadacitinib who showed a complete response after switching to abrocitinib. A 23-year-old male patient with severe AD was enrolled in the Measure Up double-blind, placebo-controlled, phase 3 randomized clinical trial. At baseline, the Eczema Area Severity Index (EASI) was 50.6, the Investigator's Global Assessment (IGA) was 4, the affected Body Surface Area (BSA) was 80%, and the Worst Pruritus-Numeric Rating Scale (WP-NRS) was 10/10 (Figure 1)...

In 1980, Hanifin and Rajka (1) proposed major and minor diagnostic criteria for atopic dermatitis (AD). Major associations included pruritus, dry skin, and history of atopy. One minor feature included Dennie-Morgan Folds (DMFs), which manifest as secondary creases in the skin underneath the inferior eyelid, usually found in infants (2). In an attempt to refine these criteria, a study evaluating 210 patients with an existing AD diagnosis observed DMF in 84% of AD cases. A pediatric study in Bijapur, India on 174 children under 16 years of age with AD identified DMF to be the most prevalent minor criterion...

Itch (pruritus) is a sensation in the skin that provokes the desire to scratch. The sensation of itch is mediated through a subclass of primary afferent sensory neurons, termed pruriceptors, which express molecular receptors that are activated by itch-evoking ligands. Also expressed in pruriceptors are several types of Transient Receptor Potential (TRP) channels. TRP channels are a diverse class of cation channels that are responsive to various somatosensory stimuli like touch, pain, itch, and temperature. In pruriceptors, TRP channels can be activated through intracellular signaling cascades initiated by pruritogen receptors and underly neuronal activation...
