Atopic

INTRODUCTION: Atopic dermatitis is associated with intense itch, which has been shown to cause sleep disruption that significantly impacts the lives of patients with atopic dermatitis. Despite this, little is known about its burden to the healthcare system and society. This study aimed to quantify the economic burden of itch-related sleep loss in moderate-to-severe atopic dermatitis in the UK. METHODS: A literature-based decision-analytic model was developed from a healthcare payer and societal perspective...

PURPOSE: Only a few studies have focused on the brain mechanisms underlying the itch processing in AD patients, and a neural biomarker has never been studied in AD patients. We aimed to develop a deep learning model-based neural signature which can extract the relevant temporal dynamics, discriminate between AD and healthy control (HC), and between AD patients who responded well to acupuncture treatment and those who did not. PATIENTS AND METHODS: We recruited 41 AD patients (22 male, age mean ± SD: 24...

Food protein-induced allergic proctocolitis (FPIAP) is a non-IgE-mediated allergic condition that presents with hematochezia in otherwise healthy infants. It is most commonly induced by cow's milk protein via breast milk or formula. The prognosis for FPIAP is generally considered favorable with most infants achieving symptomatic resolution after diet modification. Most infants go on to tolerate the offending foods by 1-3 years of age. Over 8 years at our institution, five patients were identified and noted to have FPIAP to cow's milk during infancy with subsequent development of IgE-mediated allergic reaction to cow's milk and other foods...

BACKGROUND: Psoriasis (P) and atopic dermatitis (AD) share some common characteristics. The resulting clinical picture with shared manifestations is a new entity called psoriasis dermatitis (PD), atopic psoriasis or psorema. The purpose of this study was to identify the clinical manifestations of this new dermatological condition, focusing on the adult population. METHODS: We recruited adult patients from two outpatient clinics, the "severe psoriasis" and the "adult atopic dermatitis," between January 1st , 2021, and December 31st , 2021...

Atopic dermatitis (AD) is a chronic inflammatory skin disease with a significant clinical, economic, and human burden. The JAK1 Atopic Dermatitis Efficacy and Safety (JADE) program's Phase 3 trials demonstrated that as a treatment for moderate-to-severe AD in adults with previous exposure to immunotherapy, abrocitinib showed superior efficacy and safety compared with standard of care (SoC), consisting of topical corticosteroids. This study assessed the cost-effectiveness of abrocitinib with SoC versus SoC alone for this patient population in Japan from a societal perspective...

BACKGROUND: Medical rehabilitation plays an important role in the management of patients with chronic dermatoses and dermato-oncological diseases. OBJECTIVES: Which dermatological indications qualify for a medical rehabilitation? What forms need to be completed for a successful application? Which treatments are provided and what are goals to be accomplished during dermatological rehabilitation? MATERIALS AND METHODS: Evaluation of current guidelines, directives, and recommendations as well as exemplary reviews...

BACKGROUND: Atopic dermatitis (AD) is a known risk factor for the development of food allergy. Prior work has suggested disparities in diagnosis/management of food allergy in urban populations. OBJECTIVE: We aimed to determine whether socioeconomic conditions, as measured by the Area Deprivation Index (ADI) and insurance status, or racial/ethnic self-identity were associated with risk of food allergy diagnosis (DFA), evaluation by an allergist, or objective food allergy testing among high-risk children with atopic dermatitis...

BACKGROUND: Psoriasis is a chronic inflammatory dermatosis whose clinical and topographic distribution requires differential diagnosis, or the possible association with allergic contact dermatitis (ACD), requiring patch testing (PT) as part of the diagnostic procedure. OBJECTIVES: To describe the epidemiological, clinical, and allergic profile of patients with a primary or secondary diagnosis of psoriasis undergoing PT and compare them with patients with a diagnosis of ACD at the end of the diagnostic process...

BACKGROUND: A significant association between atopic dermatitis and leaky gut syndrome has been demonstrated in humans. No studies have been conducted to determine whether there is an association between atopic dermatitis and intestinal damage in dogs. OBJECTIVES: This study aimed to determine whether there is an association between canine atopic dermatitis and intestinal damage using selected intestinal-related biomarkers. METHODS: Twenty-six dogs with atopic dermatitis and 10 healthy dogs were included...

BACKGROUND: Atopic dermatitis ranks among the prevalent skin disorders. Research has indicated a potential association with brain cancer. Yet, establishing a direct causal relationship between atopic dermatitis and brain cancer continues to be challenging. MATERIALS AND METHODS: We extracted single nucleotide polymorphisms (SNPs) significantly associated with atopic dermatitis (sample size = 382 254) at a genome-wide level from a large Finnish Genome-Wide Association Study (GWAS) dataset (n cases = 15 208, n controls = 367 046)...

Commonly used medical terms like "obesity" and "overweight" have been identified as stigmatizing. Thus, this study sought to revise a commonly used measure of weight stigmatizing attitudes, the Attitudes Toward Obese Persons (ATOP) scale. We compared the original terminology in the ATOP (e.g., "obese")to a modified version using neutral terms (e.g., "higher weight"). We randomized participants ( N  = 599) to either receive the original or modified ATOP and compared their scores. There was no significant difference between the scores of participants who received the original ATOP and the modified ATOP, t (597) = -2...

A compromised permeability barrier is a hallmark of atopic dermatitis (AD). Localized to the outermost skin layer, the stratum corneum (SC) is critically dependent on terminal differentiation of epidermal keratinocytes, which transform into protein-rich corneocytes surrounded by extracellular lamellae of unique epidermal lipids, conferring permeability barrier function. These structures are disrupted in AD. A leaky barrier is prone to environmental insult, which in AD elicits type 2-dominant inflammation, in turn resulting in a vicious cycle further impairing the SC structure...

Histamine 4 receptor (H4R), the most recently identified subtype of histamine receptor, primarily induces inflammatory reactions upon activation. Several H4R antagonists have been developed for the treatment of inflammatory bowel disease (IBD) and atopic dermatitis (AD), but their use has been limited by adverse side effects, such as a short half-life and toxicity. Natural products, as an important source of anti-inflammatory agents, offer minimal side effects and reduced toxicity. This work aimed to identify novel H4R antagonists from natural products...

The association between molluscum contagiosum and concomitant atopic dermatitis and its impact on clinical features and treatment outcomes remains unclear. This retrospective study, conducted in the paediatric dermatology clinic of a tertiary medical centre, aimed to compare molluscum patients with and without atopic dermatitis. A total of 615 children with molluscum were included, 13.17% of whom had atopic dermatitis. While the latter group exhibited higher lesion count and itchiness (p=0.026 and p=0.044, respectively), no significant differences were observed in average lesion diameter, ulceration, purulence, and erythema (p=0...

3 D human epidermal equivalents (HEEs) are a state-of-the-art organotypic culture model in pre-clinical investigative dermatology and regulatory toxicology. Here, we investigated the utility of electrical impedance spectroscopy (EIS) for non-invasive measurement of HEE epidermal barrier function. Our setup comprised a custom-made lid fit with 12 electrode pairs aligned on the standard 24-transwell cell culture system. Serial EIS measurements for seven consecutive days did not impact epidermal morphology and readouts showed comparable trends to HEEs measured only once...
