Abstract
OBJECTIVE Autoimmune dermatosis (AID) occurs when the body's immune system attacks skin or tissue, leading to various types of skin disorders or injuries. Recent studies show that Janus kinases (JAKs) play critical roles in autoimmune diseases including AID by regulating multiple cytokine signaling pathways. CS12192, a novel JAK3/JAK1/TBK1 inhibitor, has been reported to exert ameliorative effects in rheumatoid arthritis. However, the efficacy of CS12192 on AID is undetermined. This study aims to investigate the therapeutic efficacy of CS12192 on psoriasis (PSO), systemic lupus erythematosus (SLE) and atopic dermatitis (AD) in mouse models. METHODS Interleukin-23 (IL-23)-induced PSO model, spontaneous SLE model of MRL/MpJ-Faslpr/J (MRL/lpr) mice, and oxazolone (OXA) and dinitrochlorobenzene (DNCB)-induced murine AD models were used for the evaluation of curative effects of CS12192, respectively. The skin lesion, biochemical parameters, ear thickness, ear weight and histopathology were assessed accordingly. RESULTS In PSO model, mice treated with CS12192 show reduced ear thickness and ear weight as compared with vehicle. In SLE model, CS12192 ameliorates cutaneous parameters such as lymphadenectasis and skin lesion but not systematic parameters such as proteinuria concentration and score, serum dsDNA and BUN concentration. In AD models, CS12192 dose-dependently improves ear swelling and reduces histological scores, exerting equivalent efficacy with baricitinib, a marketed JAK1/JAK2 inhibitor. CONCLUSION Our findings suggest that the novel JAK3/JAK1/TBK1 inhibitor CS12192 is potentially to alleviate autoimmune dermatosis.

Abstract
Background: There is controversy on whether allergic contact dermatitis (ACD) is associated with atopy. Research on eczema and the risk of ACD is mixed, and there is sparse literature on other atopic conditions. Objective: Our study examined the prevalence of several atopic conditions, including allergic rhinitis, eczema, asthma, and food allergies in patients with ACD, and compared these to patients without ACD. Methods: We retrospectively reviewed adult patients ages ≥ 18 years with ACD (n = 162) with positive patch testing results and documented any history of atopy, including childhood eczema, asthma, allergic rhinitis, and immunoglobulin E-mediated food allergy. The prevalence of atopic conditions was compared between our ACD cohort and controls without ACD (n = 163) from our electronic medical records system (age and gender matched). Results: Among our patients with ACD, 53 (33%) had allergic rhinitis, 22 (14%) had childhood eczema, 32 (20%) had asthma, and 8 (5%) had food allergies. We observed that the odds of atopy overall (n = 76) in the ACD group compared with the control group were increased (odds ratio [OR] 1.88; p = 0.007). Allergic rhinitis was the highest risk factor (n = 53) with an OR of 12.64 (p < 0.001). Childhood eczema (n = 22) was also increased in the ACD group (OR 2.4; p = 0.026). The odds of asthma and food allergy in the ACD group were also increased; however, the difference was not statistically significant from the control group (OR 1.76 [p = 0.071] and OR 2.76 [p = 0.139], respectively). Conclusion: Patients with ACD had increased odds of eczema, allergic rhinitis, and atopic conditions overall. Asthma and food allergies were not found to have a statistically significant correlation. Larger studies that delve into atopic risk factors in ACD would be important to confirm these findings.

MEDICINA (KAUNAS, LITHUANIA) 2024; 60:968. [PMID: 38929585 PMCID: PMC11205604 DOI: 10.3390/medicina60060968] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/10/2024] [Revised: 06/01/2024] [Accepted: 06/08/2024] [Indexed: 06/28/2024]
Abstract
Background and Objectives: This study demonstrates the factor structure and reliability of the Croatian version of the TOPICOP (Topical Corticosteroid Phobia) questionnaire, thereby contributing to further validation and standardization of the measurement of topical corticophobia with dermatological patients or their parents, which directly affects patient or parent compliance, as well as the final therapeutic effect. Materials and Methods: The cross-sectional, observational study was conducted at the University Hospital Centre Split, Department of Dermatovenerology. The research involved inviting 120 participants (age 12-68) who attended the University Hospital Centre Split's Atopy School, patients examined in the Dermatology Outpatient Clinic of the University Hospital Centre Split and diagnosed with atopic dermatitis (AD) or allergic contact dermatitis (ACD), and parents or legal representatives of patients younger than 12 years old. The TOPICOP questionnaire consists of 12 items assessing the three different components of topical corticophobia (worries, beliefs, and behaviour). Respondents evaluated their perception of the correctness of each statement within 10 min of filling out the questionnaire on a four-point Likert scale. Results: The response rate was 94%, resulting in a sample of 113 respondents (109 adults and 4 children). Factor analysis yielded one common factor of relatively high reliability (Cronbach α = 0.85, 95% CI 0.81 to 0.89). No differences were found in questionnaire scores between male and female participants, nor between the parents/legal representatives of dermatological patients and other patients. Conclusions: This research contributes to further development of the appropriate measuring instrument, its practical application, and thus, the better recognition, resolution, and prevention of topical corticophobia as part of the better overall healthcare and treatment of chronic dermatological patients.

Abstract
Acrylates and methacrylates are widely used in dental and orthopedic prostheses, false nails, adhesives, glues, and paints, and are strong sensitizers. The aim of our study was to assess the prevalence of acrylate sensitization in patients before the application of dental or orthopedic prostheses or after the application in case of potentially related contact dermatitis. Methods: The subjects were tested according to haptens reported in safety data sheets, including methyl methacrylate (MMA) 5%, methyl acrylate (MA) 1%, ethyl methacrylate (EMA) 2%, ethyl acrylate (EA) 1%, butylacrylate 0.1%, 2 hydroxyethyl methacrylate (HEMA) 5%, ethylene glycol dimethacrylate 2% (EGDMA), tetraethylene glycol dimethacrylate 2% (TEGDMA), and dimethyl amino ethyl methacrylate 0.2% (DAEMA). Multivariable logistic regression was used to study the factors associated with (meth)acrylate sensitization. Results: Six hundred sixty-five patients (75.4% of the total sample) without contact dermatitis before the placement of any dental or orthopedic prosthesis and 217 patients (24.6% of the total sample) with contact dermatitis potentially due to already placed prostheses were involved. In total, 37 cases of patch test positivity to at least 1 acrylate (4.2%) were found. In the pre-implant population, previous dermatitis and respiratory allergy were associated with increased sensitization to acrylates in multivariable regression analysis (odds ratio [OR] 2.38, 95% confidence interval [CI] 1.05-5.39; OR 2.96, 95% CI 1.32-6.64, respectively). The prevalence of sensitization was 3.5% for EGDMA, 2.7% for EA, 1.5% for 2-HEMA, 1.4% for both MA and MMA, 1.28% for DAEMA, and 0.8% for EMA. No statistically significant difference was found in the prevalence of sensitization between the pre- and post-implant groups. Discussion: Our study found a similar profile of sensitization in pre-implant and post-implant patients, suggesting the need to better study the specificity and sensitivity of patch tests to (meth)acrylate and to define relevance considering a detailed history of exposure.

Abstract
The skin acts as the body's primary physical and immune barrier, maintaining the skin microbiome and providing a physical, chemical, and immune barrier. A disrupted skin barrier plays a critical role in the onset and advancement of inflammatory skin conditions such as atopic dermatitis (AD) and contact dermatitis. This narrative review outlines the relationship between AD and skin barrier function in preparation for the search for possible markers for the treatment of AD.

Abstract
Dermatitis, the incendiary reaction of the skin to various components, can manifest in various types, including atopic dermatitis, contact dermatitis, nummular eczema, seborrhoea, and stasis dermatitis. Atopic dermatitis is the most common skin disease in children and has a growing prevalence in recent years. It is characterized by extreme tingling, eczemous skin injuries, dryness of the skin, and a family history of atopic illnesses. Contact dermatitis (CD) is a common, irritating skin disorder caused by allergens and aggravating elements in the environment. It is the most common cause of work-related dermatitis and plays a substantial role in hand and face dermatitis. A complete restorative history is essential for establishing CD and identifying the allergies that cause it. Fix testing, skin tests for fast contact reactions, serum allergen-specific IgE testing, subjective and quantitative evaluation of allergens inside probable items patients were exposed to, and challenge testing are among the other diagnostic techniques. To avoid a breakdown and the continuation of the skin illness, early and suitable therapy is critical. Allergic dermatitis to contact (ACD) develops during the normal, delayed incendiary reaction and has a perplexing etiology. Accurate identification of the allergen that is causing the reaction allows for adequate individual avoidance. The major treatment alternatives continue to be corticosteroids. Nickel-contact dermatitis is an allergic reaction that affects both children and adults. Adverse contact dermatitis (ACD) is a frequent skin reaction to a common allergen that can affect both children and adults. Less than 10% of all diagnostic procedures in pediatric patients involve checking for ACD symptoms. To answer the clinical question, a thorough history is gathered based on appearance, age group, and dermatitis type. According to pediatricians in the US, metals, perfumes, topical antimicrobials, excessive chemicals, and fabric softeners are the most typical allergens.

Abstract
BACKGROUND The development of atopic dermatitis (AD) drugs is challenged by many disease phenotypes and trial design options, which are hard to explore experimentally. OBJECTIVE We aimed to optimize AD trial design using simulations. METHODS We constructed a quantitative systems pharmacology model of AD and standard of care (SoC) treatments and generated a phenotypically diverse virtual population whose parameter distribution was derived from known relationships between AD biomarkers and disease severity and calibrated using disease severity evolution under SoC regimens. RESULTS We applied this workflow to the immunomodulator OM-85, currently being investigated for its potential use in AD, and calibrated the investigational treatment model with the efficacy profile of an existing trial (thereby enriching it with plausible marker levels and dynamics). We assessed the sensitivity of trial outcomes to trial protocol and found that for this particular example the choice of end point is more important than the choice of dosing regimen and patient selection by model-based responder enrichment could increase the expected effect size. A global sensitivity analysis revealed that only a limited subset of baseline biomarkers is needed to predict the drug response of the full virtual population. CONCLUSIONS This AD quantitative systems pharmacology workflow built around knowledge of marker-severity relationships as well as SoC efficacy can be tailored to specific development cases to optimize several trial protocol parameters and biomarker stratification and therefore has promise to become a powerful model-informed AD drug development and personalized medicine tool.

Abstract
INTRODUCTION Allergic contact dermatitis (ACD) is a common cutaneous inflammatory skin disorder that is diagnosed via epicutaneous patch testing (PT). ACD may also coexist with other systemic inflammatory conditions such as atopic dermatitis and psoriasis. Many of the treatments used to manage severe ACD, along with other systemic conditions, interact with and suppress the immune system, thereby potentially interfering with the mechanism of PT. There is uncertainty in the literature regarding the effects of immunosuppression on the results of PT. METHODS A comprehensive literature review was conducted using PubMed and Google Scholar to identify articles relevant to the topic of this review. Only articles available in English were included. AREAS COVERED This review discusses the impact of immunomodulating therapies on the results of PT. We summarize the available evidence and provide updated recommendations for several immunomodulating drugs commonly used in patients undergoing PT. EXPERT OPINION In general, the results of PT are most reliable when performed without immunosuppression. If this is not feasible, it is best to have patients on as low a dose of immunosuppression as possible, but it may not be necessary to stop or change an immunomodulating drug prior to PT.

Abstract
The CD1 and MR1 protein families present lipid antigens and small molecules to T cells, complementing well-studied major histocompatibility complex-peptide mechanisms. The CD1a subtype is highly and continuously expressed within the skin, most notably on Langerhans cells, and has been demonstrated to present self and foreign lipids to T cells, highlighting its cutaneous sentinel role. Alteration of CD1a-dependent T-cell responses has recently been discovered to contribute to the pathogenesis of several inflammatory skin diseases. In this review, we overview the structure and role of CD1a and outline the current evidence implicating CD1a in the development of psoriasis, atopic dermatitis and allergic contact dermatitis.

Abstract
Personal care products (PCPs) commonly cause allergic contact dermatitis (ACD). Skincare companies often market their products as 'hypoallergenic'; however, this term is not regulated by industry standards. To determine whether PCPs marketed as hypoallergenic are truly less likely to precipitate ACD, we conducted a study of ingredients found in 'hypoallergenic PCPs' from two major UK retailers in 2022. Of 208 products meeting the inclusion criteria, 153 (73.6%) contained at least 1 allergen or related chemical from the British Society for Cutaneous Allergy baseline series, 21 (10.1%) had 2 potential allergens and 4 PCPs (1.9%) had 3 allergens. Cetearyl alcohol was the most common -allergen identified in leave-on PCPs and parabens in rinse-off products; fragrance was the most frequent related chemical found in 85 PCPs (40.1%). A high prevalence of common allergens was found in hypoallergenic PCPs, suggesting that dermatologists and consumers should be cautious of product ingredients.

Abstract
The discovery of Mas-related G protein-coupled receptors (Mrgprs) has opened a compelling chapter in our understanding of immunity and sensory biology. This family of receptors, with their unique expression and diverse ligands, has emerged as key players in inflammatory states and hold the potential to alleviate human diseases. This review will focus on the members of this receptor family expressed on immune cells and how they govern immune and neuro-immune pathways underlying various physiological and pathological states. Immune cell-specific Mrgprs have been shown to control a variety of manifestations, including adverse drug reactions, inflammatory conditions, bacterial immunity, and the sensing of environmental exposures like allergens and irritants.

Abstract
Inflammatory diseases involve numerous disorders and medical conditions defined by an insufficient level of self-tolerance. These diseases evolve over the course of a multi-step process through which environmental variables play a crucial role in the emergence of aberrant innate and adaptive immunological responses. According to experimental data accumulated over the past decade, neutrophils play a significant role as effector cells in innate immunity. However, neutrophils are also involved in the progression of numerous diseases through participation in the onset and maintenance of immune-mediated dysregulation by releasing neutrophil-derived molecules and forming neutrophil extracellular traps, ultimately causing destruction of tissues. Additionally, neutrophils have a wide variety of functional heterogeneity with adverse effects on inflammatory diseases. However, the complicated role of neutrophil biology and its heterogeneity in inflammatory diseases remains unclear. Moreover, neutrophils are considered an intriguing target of interventional therapies due to their multifaceted role in a number of diseases. Several approaches have been developed to therapeutically target neutrophils, involving strategies to improve neutrophil function, with various compounds and inhibitors currently undergoing clinical trials, although challenges and contradictions in the field persist. This review outlines the current literature on roles of neutrophils, neutrophil-derived molecules, and neutrophil heterogeneity in the pathogenesis of autoimmune and inflammatory diseases with potential future therapeutic strategies.

Prevalence of allergic contact dermatitis in children with and without atopic dermatitis: A multicenter retrospective case-control study. J Am Acad Dermatol 2023; 89:1007-1014. [PMID: 37768237 DOI: 10.1016/j.jaad.2023.06.048] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/04/2023] [Revised: 06/19/2023] [Accepted: 06/27/2023] [Indexed: 09/29/2023]
Abstract
BACKGROUND As both allergic contact dermatitis and atopic dermatitis (AD) have similar clinical presentations and are characterized by spongiotic dermatitis on skin biopsy, many children with AD are not referred for patch testing and allergic contact dermatitis is underdiagnosed. OBJECTIVE To provide updated prevalence data of common contact allergens in children with and without AD. METHODS This is a retrospective case-control study using the Pediatric Allergic Contact Dermatitis Registry from 2018 to 2022. RESULTS A total of 912 children were included (615 with AD and 297 without AD). Children with AD were more likely to have a longer history of dermatitis (4.1 vs 1.6 years, P < .0001), have seen more providers (2.3 vs 2.1, P = .003), have greater than 1 positive patch test (PPT) result (P = .005), have a greater number of PPT results overall (2.3 vs 1.9, P = .012), and have a more generalized distribution of dermatitis (P = .001). PPT to bacitracin (P = .030), carba mix (P = .025), and cocamidopropyl betaine (P = .0007) were significantly increased in children with AD compared to those without AD. LIMITATIONS Technical variation between providers and potential for misclassification, selection, and recall biases. CONCLUSION Children with AD are significantly more likely to have PPT reactions and should be referred for evaluation of allergic contact dermatitis and obtain patch testing.

Tolerogenic phenotype of dendritic cells is induced after hapten sensitization followed by attenuated contact hypersensitivity response in atopic dermatitis model NC/Nga mice. Biochem Biophys Res Commun 2023; 678:24-32. [PMID: 37611349 DOI: 10.1016/j.bbrc.2023.08.042] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/30/2023] [Revised: 08/10/2023] [Accepted: 08/17/2023] [Indexed: 08/25/2023]
Abstract
Allergic contact dermatitis (ACD) and atopic dermatitis (AD) are common inflammatory diseases. We previously reported attenuated contact hypersensitivity (CHS) responses in AD model mice using 2,4-dinitrofluorobenzene, reflecting clinical experiments. However, previous studies have not addressed the commonality of findings across haptens and mechanisms focused on dendritic cells (DCs). Thus, this study evaluated CHS responses to fluorescein isothiocyanate (FITC) and DC migration and maturation in the sensitization phase of CHS in AD. CHS responses to FITC were compared between NC/Nga mice without and with AD induction (non-AD and AD mice, respectively). T-cell responses and DC migration and maturation after FITC-induced sensitization were examined in the draining lymph nodes of non-AD and AD mice. AD mice demonstrated reduced CHS responses to FITC under decreased T-cell proliferation following sensitization and interferon-γ production by hapten-specific T cells compared with non-AD mice. In addition, the number of FITC+CD11c+MHC class IIhigh migratory DCs 24 h after FITC sensitization was comparable between non-AD and AD mice. However, FITC+CD11c+MHC class IIhigh migratory DCs in AD mice exhibited lower expression levels of CD80 and CD86 and higher expression levels of PD-L1 and mRNA of transforming growth factor beta than non-AD mice. These findings suggest that attenuated CHS responses may be hapten-independent and the induction of the tolerogenic phenotype of hapten-bearing DCs can contribute to reduced T-cell proliferation after sensitization and CHS responses in AD.

Abstract
OBJECTIVES There is a scarcity of evidence on occupational exposures that may increase eczema in adults. We aimed to investigate potential associations between occupational exposures and eczema in middle-aged adults. METHODS A lifetime work history calendar was collected from the Tasmanian Longitudinal Health Study participants when they were at age 53. Their work history was collated with the occupational asthma-specific job exposure matrix to define ever-exposure and cumulative exposure unit-years since no eczema job exposure matrix is available. Eczema was determined using the report of flexural rash that was coming and going for at least 6 months in the last 12 months. Skin prick tests were used to further subgroup eczema and atopic eczema (AE) or non-AE (NAE). Logistic and multinomial regression models were used to investigate the associations. RESULTS Eczema prevalence was 9.1%. Current occupational exposure to animals (adjusted OR, aOR=3.06 (95% CI 1.43 to 6.58)), storage mites (aOR=2.96 (95% CI 1.38 to 6.34)) and endotoxin (aOR=1.95 (95% CI 1.04 to 3.64)) were associated with increased risk of current eczema. Furthermore, increased odds of NAE were associated with current exposure to animals (aOR=5.60 (95% CI 1.45 to 21.7)) and storage mites (aOR=5.63 (95% CI 1.45 to 21.9)). Current exposures to isocyanates (aOR=5.27 (95% CI 1.17 to 23.7)) and acrylates (aOR=8.41 (95% CI 1.60 to 44.3)) were associated with AE. There was no evidence of associations between cumulative exposures and eczema prevalence. Cumulative exposure to metalworking fluids (aOR=1.10 (95% CI 1.01 to 1.22)) was associated with NAE and acrylates (aOR=1.24 (95% CI 1.04 to 1.46)) with AE. CONCLUSIONS In this exploratory assessment, multiple occupational exposures were associated with current eczema in middle-aged adults. Raising awareness and limiting these exposures during an individual's productive working life will likely have various health benefits, including reducing eczema prevalence.

Abstract
Nanoparticle (NP) skin exposure is linked to an increased prevalence of allergic contact dermatitis. In our prior studies using the mouse contact hypersensitivity (CHS) model, we reported that silica 20 nm (SiO2) NPs suppressed the allergic response and titanium dioxide NPs doped with manganese (mTiO2) exacerbated it. In this work, we conducted in vitro experiments using bone marrow-derived dendritic cells (BMDCs) to study the combinatorial effect of the potent 2,4-dinitrofluorobenzene (DNFB) hapten sensitizer with SiO2 and mTiO2 NPs on BMDC cytotoxicity, cytokine secretion and phenotype using the B7 family ligands. Results show that DNFB and mTiO2 behave similarly and exhibit proinflammatory characteristics while SiO2 promotes a naive phenotype. We observe that the B7-H3 (CD276) ligand is only expressed on CD80 + (B7-1) BMDCs. Results from adoptive transfer CHS studies, combined with BMDC phenotype analysis, point to the importance of PD-L2 expression in modulating the adaptive immune response. This work identifies metrics that can be used to predict the effects of NPs on contact allergy and to guide efforts to engineer cell-based therapies to induce hapten specific immune tolerance.

Abstract
Under physiological conditions, skin mast cells play an important role as guardians that quickly react to stimuli that disturb homeostasis. These cells efficiently support, fight infection, and heal the injured tissue. The substances secreted by mast cells allow for communication inside the body, including the immune, nervous, and blood systems. Pathologically non-cancerous mast cells participate in allergic processes but also may promote the development of autoinflammatory or neoplastic disease. In this article, we review the current literature regarding the role of mast cells in autoinflammatory, allergic, neoplastic skin disease, as well as the importance of these cells in systemic diseases with a pronounced course with skin symptoms.

Abstract
Atopic dermatitis is a chronic inflammatory disease that is multifactorial in nature. Allergic contact dermatitis and protein contact dermatitis are allergic conditions that may occur in the context of atopic dermatitis and be the cause of exacerbations. Although the prevalence of allergic contact dermatitis is similar in atopic patients and the general population, these 2 conditions are frequently associated because atopic inflammation disrupts the skin barrier. Skin tests are therefore recommended in atopic individuals. Dupilumab could be useful for treating allergic contact dermatitis if it is mediated by type 2 helper T cells but could exacerbate inflammation if mediated by TH1 cells: further study is needed before conclusions can be drawn. Although the mechanism by which exposure to environmental proteins exacerbates atopic dermatitis remains under discussion, such exacerbations are routinely seen in clinical practice. Prick testing is recommended in symptomatic atopic dermatitis. When prick-test findings are positive, patients should be advised to avoid the culprit substances.

Abstract
OBJECTIVES Ozone is widely applied to treat allergic skin diseases such as eczema, atopic dermatitis, and contact dermatitis. However, the specific mechanism remains unclear. This study aims to investigate the effects of ozonated oil on treating 2,4-dinitrochlorobenzene (DNCB)-induced allergic contact dermatitis (ACD) and the underling mechanisms. METHODS Besides the blank control (Ctrl) group, all other mice were treated with DNCB to establish an ACD-like mouse model and were randomized into following groups: a model group, a basal oil group, an ozonated oil group, a FcεRI-overexpressed plasmid (FcεRI-OE) group, and a FcεRI empty plasmid (FcεRI-NC) group. The basal oil group and the ozonated oil group were treated with basal oil and ozonated oil, respectively. The FcεRI-OE group and the FcεRI-NC group were intradermally injected 25 µg FcεRI overexpression plasmid and 25 µg FcεRI empty plasmid when treating with ozonated oil, respectively. We recorded skin lesions daily and used reflectance confocal microscope (RCM) to evaluate thickness and inflammatory changes of skin lesions. Hematoxylin-eosin (HE) staining, real-time PCR, RNA-sequencing (RNA-seq), and immunohistochemistry were performed to detct and analyze the skin lesions. RESULTS Ozonated oil significantly alleviated DNCB-induced ACD-like dermatitis and reduced the expressions of IFN-γ, IL-17A, IL-1β, TNF-α, and other related inflammatory factors (all P<0.05). RNA-seq analysis revealed that ozonated oil significantly inhibited the activation of the DNCB-induced FcεRI/Syk signaling pathway, confirmed by real-time PCR and immunohistochemistry (all P<0.05). Compared with the ozonated oil group and the FcεRI-NC group, the mRNA expression levels of IFN-γ, IL-17A, IL-1β, IL-6, TNF-α, and other inflammatory genes in the FcεRI-OE group were significantly increased (all P<0.05), and the mRNA and protein expression levels of FcεRI and Syk were significantly elevated in the FcεRI-OE group as well (all P<0.05). CONCLUSIONS Ozonated oil significantly improves ACD-like dermatitis and alleviated DNCB-induced ACD-like dermatitis via inhibiting the FcεRI/Syk signaling pathway.

Abstract
Allergic contact dermatitis (ACD) is an allergen-specific T-cell-mediated inflammatory response, albeit with unclear pathogenesis. Exosomes are nanoscale extracellular vesicles secreted by several cell types and widely distributed in various biological fluids. Exosomes affect the occurrence and development of ACD through immunoregulation among other ways. Nevertheless, the role of exosomes in ACD warrants further clarification. This review examines the progress of research into exosomes and their involvement in the pathogenesis, diagnosis, and treatment of ACD and provides ideas for exploring new diagnostic and treatment methods for this disease.

Abstract
Atopic dermatitis is a chronic inflammatory disease that is multifactorial in nature. Allergic contact dermatitis and protein contact dermatitis are allergic conditions that may occur in the context of atopic dermatitis and be the cause of exacerbations. Although the prevalence of allergic contact dermatitis is similar in atopic patients and the general population, these 2 conditions are frequently associated because atopic inflammation disrupts the skin barrier. Skin tests are therefore recommended in atopic individuals. Dupilumab could be useful for treating allergic contact dermatitis if it is mediated by type 2 helper T cells but could exacerbate inflammation if mediated by TH1 cells: further study is needed before conclusions can be drawn. Although the mechanism by which exposure to environmental proteins exacerbates atopic dermatitis remains under discussion, such exacerbations are routinely seen in clinical practice. Prick testing is recommended in symptomatic atopic dermatitis. When prick-test findings are positive, patients should be advised to avoid the culprit substances.

Abstract
Background/Objectives The lip is a unique tissue type that acts as a “barrier” to the mouth and receives many external stimuli. It is also a common symptom in atopic dermatitis. Dupilumab was the first targeted biological drug approved for the treatment of moderate-to-severe atopic dermatitis (AD). There is no real-world clinical data on the use of dupilumab in patients with AD and cheilitis. This retrospective study compared the improvement in skin lesions in AD patients with cheilitis after dupilumab treatment and evaluated the improvement in cheilitis. Methods This is a retrospective case series. We investigated patients with AD treated with dupilumab in our department from September 2020 to May 2022, including those with cheilitis. Demographic information such as age, sex, AD or other atopy history, and the anatomical site of dermatitis was collected. Disease severity was assessed using the eczema area and severity index score (EASI), body surface area (BSA), and severity assessment of cheilitis (the cheilitis symptom score) at baseline and after 16 weeks. Results We reviewed 96 patients treated with dupilumab for AD, and including the 10 patients with cheilitis (10.4%). All patients demonstrated significant improvement in skin lesions, and lip symptoms improved in seven patients. Among AD patients with improved cheilitis, the average reduction in EASI was 35.0% for BSA (34.9%) and the cheilitis symptom score was 29.9% at week 8. At week 16, compared with the baseline score, the improvement in cheilitis symptom scores was 58.1%, EASI was 60.8%, and BSA was 56.2%, respectively. Conclusion Effective treatment of both the skin and cheilitis was achieved with dupilumab. The improvement in cheilitis involvement was slower than that in skin lesions. This case series confirms that dupilumab could be a valuable approach for treating patients with atopic dermatitis-associated lip involvement.

Abstract
Eczematous diseases (contact dermatitis, atopic dermatitis, hand eczema) are among the most frequent findings in dermatological clinical practice. A large body of evidence exists on structural and functional skin barrier damage in eczematous diseases, and on the importance of interventions aimed to repair such damage. While there is substantial agreement on pharmacological treatment, more sparse data are available on role, indications and usefulness of topical non-pharmacological treatments, despite significant research and progress in the composition and technology of emollients, cleansers and barrier creams significantly changed and expanded the functional activities of these products. This often leads to inadequate prescription and/or use, which increase individual and social costs of the disease and make the products useless or, in some cases, even counterproductive. This consensus document, discussed and compiled in a series of meetings by a group of Italian dermatologists experienced in the field of eczematous diseases, summarizes epidemiology and clinical features of the nosological entities of the "eczema family", illustrates the chemical/biochemical structure of emollients, cleansers and barrier creams, and aims to help physicians to exploit the full potential of available products, by providing a detailed but practical guide on characteristics, indications and correct use of non-pharmacological treatments currently available for eczematous diseases.

Abstract
Introduction Atopic dermatitis (AD) data are scarce in Dubai [United Arab Emirates (UAE)]. Therefore, this study aimed at understanding real-world healthcare resource utilization (HCRU) and related costs, specialties, treatment landscape, consultation-based prevalence and incidence, and patient characteristics. Methods This retrospective, longitudinal, insurance e-claims (Dubai Private Insurance-insured expatriates) database studied AD in Dubai between 1 January 2014 and 31 March 2020. Two cohorts of patients based on treatment status as the eligibility criteria were selected from 442,956 patients with at least two AD diagnosis claims: treated AD [mild to moderate (10,134 patients) and moderate to severe (3515 patients)] and untreated or on drugs not included in the treated AD cohort (10,806 patients). Results Across treated AD (mild to moderate and moderate to severe) and untreated AD cohorts, mean age was ~ 29 years; the majority were from dermatology (65-44%) and pediatrics (29-32%) specialty. Key HCRU cost contributors were hospitalizations and outpatient visits in both the treated AD groups. Mean annual disease-specific HCRU cost per patient was highest for the moderate-to-severe treated (531.5 USD) cohort, followed by the mild-to-moderate treated (378.4 USD) cohort, and lowest for the untreated (144.0 USD) cohort; patients with AD with any infection, asthma, or allergic rhinitis showed a similar trend. However, AD-diagnosed patients with Staphylococcus infection had the highest mean HCRU cost among the mild-to-moderate treated AD cohort, followed by the moderate-to-severe treated AD cohort. Conclusion This study indicated AD to be a common skin disease with a prevalence rate of 4-5% in Dubai (UAE), with the majority of patients (about 90%) being treated by specialists. However, there is a significant underuse of newer innovative therapies (including biologics). Also, disease severity (moderate-to-severe AD) was associated with high direct medical cost, which could be controlled by early intervention. Furthermore, AD treatment choice could focus on major direct HCRU cost contributors such as hospitalizations, comorbid conditions, and infections.

Abstract
Atopic dermatitis (AD) is a chronic inflammatory skin disease with an increasing prevalence regionally and globally. It is characterized by intense itching and recurrent eczematous lesions. With the increase in the availability of treatment options for healthcare practitioner and patients, new challenges arise for treatment selection and approach. The current consensus statement has been developed to provide up-to-date evidence and evidence-based recommendations to guide dermatologists and healthcare professionals managing patients with AD in Saudi Arabia. By an initiative from the Ministry of Health (MOH), a multidisciplinary work group of 11 experts was convened to review and discuss aspects of AD management. Four consensus meetings were held on January 14, February 4, February 25, and March 18 of 2021. All consensus content was voted on by the work group, including diagnostic criteria, AD severity assessment, comorbidities, and therapeutic options for AD. Special consideration for the pediatric population, as well as women during pregnancy and lactation, was also discussed. The present consensus document will be updated as needed to incorporate new data or therapeutic agents.

Abstract
BACKGROUND Occupational contact dermatitis (OCD) is a skin disorder caused by contact with any substances found in the workplace. Occupational contact dermatitis is second most common occupational disease (15% of all cases of occupational disease). Occupational contact dermatitis is divided into allergic contact dermatitis (ACD) and irritant contact dermatitis (ICD) which is 80% of cases that affects hands. Batik is an art that is painted on cloth, it is one of Indonesian cultural heritage. Batik workers have a higher risk of obtaining OCD due to exposure to chemicals and fluids used during work. Natural dyes used in the dyeing process are less likely to cause ACD than standard allergens. Some of the natural dyes used in the dyeing process in batik industries are Indigofera tinctoria, sappan wood (Caesalpinia sappan), and Mahagony (Swietenia mahagoni) cause skin sensitisation. OBJECTIVE To compare the results of patch testing between natural dyes (Indigofera tinctoria, sappan wood (Caesalpinia sappan), and Mahagony (Swietenia mahagoni) with standard allergens (p-phneyldiamine 0.1%, potassium dichromate 0.5% and formaldehyde 0.1%) as a cause of ACD in batik workers in Surakarta, East Java, Indonesia. METHOD A cross-sectional study was conducted on 63 subjects batik workers with OCD in Surakarta, East Java, Indonesia. Subjects were patch tested with three standard allergens (p-phenylenediamine 0.1%, potassium dichromate 0.5%, and formaldehyde 1%) and natural dyes (Indigofera tinctoria, sappan wood (Caesalpinia sappan), and Mahagony (Swietenia mahagoni). A closed patch test was evaluated 48 and 96 hour later. Screening of OCD in batik workers in Surakarta, East Java, Indonesia was based on Nordic Occupational Skin Questionnaire NOSQ-2002, and diagnosis of OCD was based on Mathias criteria (at least 4 out of 7 criteria were met). Data were analysed using a non-parametric Chi-square test with SPSS 21 with a significant difference if the p-value < 0.05. RESULT Natural dyes significantly caused allergic contact dermatitis in batik workers in Surakarta, East Java, Indonesia than standard allergens (p = 0.016). A positive patch test was found in 11 patients, standard allergen p-phenylenediamine (PPD) 0.1% was seen on one patient, potassium dichromate 0.5% on two patients, and formaldehyde 1% on two patients. A positive patch test using Indigofera tinctoria was found at one patient, sappan wood (Caesalpinia sappan) in three patients, and Mahagony (Swietenia mahagoni) in five patients. CONCLUSION Natural dyes cause more positive patch test results in batik workers.

Abstract
Atopic dermatitis (AD) is a chronic inflammatory disease characterised by an impaired skin barrier. The prolonged use of topical preparations containing medications, emollients, fragrances and preservatives may increase the risk of contact hypersensitivity (CHS). In the Allergy Outpatient Unit of the Department of Dermatology, Venereology and Dermatooncology of Semmelweis University, 5790 adult patients were patch tested between 2007–2021 with the European Environmental Baseline Series according to international standards. Among all the tested adult patients, 723 had preservative CHS (PCHS) and 639 had AD. Among the 723 PCHS patients, 68 (9.4%) had AD; the female to male ratio was 3:1 in this group. Out of 639 AD patients, 68 had PCHS (10.6%). In the AD-PCHS group, 83.8% had CHS to methylisothiazolinone (MI) (tested from 2014), 36.8% to Kathon CG®, 16.2% to methyldibromo-glutaronitrile, 11.8% to paraben, 7.4% to formaldehyde, 4.4% to para-tert-butylphenol-formaldehyde resin and 1.5% to Quaternium-15. The most common concomitant PCHS combination was Kathon CG® + MI. Most patients (32.4%) belonged to the age group of 21–30, and skin symptoms affected mostly the limbs and face. The most common other concomitant allergens were nickel, lanolin alcohol and balsam of Peru. Preservatives (especially MI and Kathon CG®) are important contact allergens in adult AD, mostly among young women. The rate of AD in the PCHS group and the rate of PCHS in the AD group is remarkable; thus, the role of PCHS should be highlighted in the topical therapy and in the prevention of possible AD exacerbations.

Abstract
Atopic dermatitis (AD) is a common disease with a broad spectrum of clinical manifestations. AD can manifest differently in adults than children. Core AD features are similar between children and adults overall, including lesions affecting flexural areas, presence of atopy, and xerosis. Adults have more signs of chronic disease, higher prevalence and different patterns of hand eczema, and a stronger relationship of disease activity with emotional factors, whereas children with AD have more exudative lesions, perifollicular accentuation, pityriasis alba, Dennie-Morgan folds, and seborrheic dermatitis-like presentation. These differences may be due in part to pathophysiologic differences in AD in children compared with adults. Atopic diseases commonly co-occur with AD, although most do not temporally have the "atopic march." Further research is warranted to better understand the differential roles of immune dysregulation, epidermal-barrier disruption, and dysbiosis between children and adults and determine whether such differences translate into differences in therapeutic efficacy.

Abstract
BACKGROUND Atopic dermatitis is the most common inflammatory skin disease in childhood and has an important impact on quality of life, especially severe cases or those that are recalcitrant to treatments. Sensitization to allergens with the potential for allergic contact dermatitis is a factor associated with cases of recalcitrant atopic dermatitis. Understanding the relationship between atopic dermatitis, allergens, and allergic contact dermatitis is essential. In Brazil, there are no studies on sensitization to allergens found in patch tests with pediatric batteries in patients with atopic dermatitis. OBJECTIVES To verify the main sensitizing agents, the prevalence of allergic contact dermatitis and the epidemiological and clinical profile of children and adolescents with atopic dermatitis. METHODS Cross-sectional, prospective study in patients between 4 and 18 years of age, with recalcitrant atopic dermatitis, treated at the Sanitary Dermatology Outpatient Clinic (RS). All patients underwent patch tests with a battery of pediatric allergens. RESULTS The prevalence of sensitization and allergic contact dermatitis in the evaluated patients was 37.07% (20/54) and 27.7% (15/54), respectively. The most frequent allergens were: nickel sulfate (16.7%), disperse blue (5.6%), and fragrance mix I (5.6%). Nickel was associated with the female sex (p = 0.019). STUDY LIMITATIONS Sample size and selection, absence of a control group. CONCLUSIONS A proportion of patients with recalcitrant atopic dermatitis may be sensitized to different allergens and may even have developed allergic contact dermatitis. Recognizing this context is important in the prevention strategy and management of the disease.

Abstract
BACKGROUND Increased hand hygiene measures during the COVID-19 pandemic have led to an increased quantum of hand eczema (HE). OBJECTIVES To examine the effects of varying washing frequencies using current mild cleansing agents - alongside with the effect of a rehydrating cream - on the epidermal barrier function and inflammatory processes of the stratum corneum (SC). METHODS Standardized skin washings on the volar aspects of the lower arms of skin healthy volunteers were performed using the Automated Cleansing Device either 5 or 11 times within 4 hours for 60 seconds each with a standard cleanser, a lipid-containing syndet, or a lipid-containing syndet followed by one-time application of a rehydrating cream. Skin bioengineering parameters (transepidermal water loss, SC hydration, erythema, and SC pH) and biochemical / immunological parameters (IL-1α, IL-1αRA, and Natural Moisturizing Factor) of SC samples collected by tape stripping were assessed. RESULTS All applied washing procedures provided comparable, mild effects on the epidermal barrier function and skin inflammation. CONCLUSIONS Occupational skin cleansers seem to have improved regarding skin barrier damaging effects. To further corroborate this, a study design, modified on the basis of our findings, applying longer washing periods for consecutive days seems desirable. This article is protected by copyright.

Multiple Roles for Cytokines in Atopic Dermatitis: From Pathogenic Mediators to Endotype-Specific Biomarkers to Therapeutic Targets. Int J Mol Sci 2022; 23:ijms23052684.

Abstract
Atopic dermatitis (AD) is one of the most common chronic inflammatory skin diseases, which generally presents with intense itching and recurrent eczematous lesions. AD affects up to 20% of children and 10% of adults in high-income countries. The prevalence and incidence of AD have increased in recent years. The onset of AD mostly occurs in childhood, although in some cases AD may persist in adult life or even manifest in middle age (adult-onset AD). AD pathophysiology is made of a complex net, in which genetic background, skin barrier dysfunction, innate and adaptive immune responses, as well as itch contribute to disease development, progression, and chronicization. One of the most important features of AD is skin dehydration, which is mainly caused by filaggrin mutations that determine trans-epidermal water loss, pH alterations, and antigen penetration. In accordance with the “outside-inside” theory of AD pathogenesis, in a context of an altered epidermal barrier, antigens encounter epidermal antigen presentation cells (APCs), such as epidermal Langerhans cells and inflammatory epidermal dendritic cells, leading to their maturation and Th-2 cell-mediated inflammation. APCs also bear trimeric high-affinity receptors for immunoglobulin E (IgE), which induce IgE-mediated sensitizations as part of pathogenic mechanisms leading to AD. In this review, we discuss the role of cytokines in the pathogenesis of AD, considering patients with various clinical AD phenotypes. Moreover, we describe the cytokine patterns in patients with AD at different phases of the disease evolution, as well as in relation to different phenotypes/endotypes, including age, race, and intrinsic/extrinsic subtypes. We also discuss the outcomes of current biologics for AD, which corroborate the presence of multiple cytokine axes involved in the background of AD. A deep insight into the correlation between cytokine patterns and the related clinical forms of AD is a crucial step towards increasingly personalized, and therefore more efficient therapy.

Abstract
BACKGROUND Atopic dermatitis (AD) is a common chronic skin disease. Only relatively scant studies from Asian countries have attempted to quantify AD-associated healthcare utilization and costs by using population-based databases. This study aims to evaluate the AD-associated annual healthcare utilization and costs in Taiwan. METHODS A retrospective matched-cohort study was conducted by matching the AD cases with controls at a 1:4 (cases:controls) ratio, with the data for both the cases and controls being sourced from the 2017 National Health Insurance Research Database (NHIRD). The AD patients were stratified by disease severity based on their treatments. Differences in the regression-adjusted frequency of care and costs between the cases and controls were compared using t-tests by the severity level of AD. RESULTS The incremental frequency of outpatient visits per year increased with AD severity (9.60, 11.28, and 16.23 for mild, moderate, and severe cases, respectively). However, the frequency of inpatient care and emergency room visits per year showed no consistent pattern associated with disease severity. The incremental total costs per year were NT$9,511.64, NT$9,705.20, and NT$15,762.09 for mild, moderate, and severe cases, respectively, and the outpatient and drug costs accounted for 46.65%-54.82% and 17.01%-31.20% of the total costs, respectively. CONCLUSION AD was found to impose significant healthcare costs, with estimated total cost burdens of NT$3.61 billion in 2017, which is 0.314% of Taiwan's national health expenditure and 0.020% of Taiwan's gross domestic product.

Abstract
BACKGROUND Although the traditional understanding is that contact sensitisation is less frequent in atopic dermatitis (AD) patients, recent studies have shown similar or higher rates of positive patch test results in AD patients. METHODS This was a single-centre, ten-year retrospective review on contact sensitisation in patients who underwent patch testing between 2007 and 2017. The aims were to characterise the pattern of contact sensitisation and to ascertain a link between contact sensitisation and AD. RESULTS There were 4903 patients (males:females = 1:1.4; mean age 40.1 years old) included. About half (2499, 51.0%) of all patients developed at least one positive reaction. The top five frequent reactions were to nickel sulfate (45.4%), potassium dichromate (16.0%), p-phenylenediamine (13.4%), Myroxylon pereirae (11.8%) and fragrance mix I (11.2%). The overall prevalence of contact sensitisation was not significantly different between patients with or without AD. Patients with AD were less likely to develop contact allergies to budesonide and thiuram mix, and more likely to develop contact allergies to potassium dichromate. CONCLUSIONS Contact sensitisation was detected in 50% of patients patch-tested. Nickel sulfate was the most frequently sensitising allergen. The prevalence of contact allergies in atopic patients is comparable to that in non-atopic patients. This article is protected by copyright. All rights reserved.

Abstract
Dupilumab facial redness (DFR), or the development of an eczematous rash of the face and neck with dupilumab use, has been observed in recent case reports. It is estimated to impact between 4 and 43.8% of dupilumab users, including children and adults. Aside from reviewing the pathogenesis and clinical presentation, we present potential diagnostic steps (such as skin scraping, serologies, biopsy, and patch testing) and management options for DFR ranging from allergen avoidance to dupilumab interruption. It is hoped that this article will serve as a means for clinicians to familiarize themselves with DFR regarding the differential diagnosis, diagnostic tools, and treatment options associated with this phenomenon.

Abstract
Atopic dermatitis (AD) is associated with allergic comorbidities, such as asthma, allergic rhinitis (AR), and allergic contact dermatitis (ACD). The etiology of keloid is largely unknown; however, AD and keloid share inflammatory pathways characterized by T-helper cell 2 cytokines and increased dermal fibroblast activity. The prevalence of keloids has been reported to increase in patients with AD, but it remains controversial. This study aimed to estimate the prevalence of keloids in patients with AD, and compare it with the prevalence of other comorbidities of AD. We assessed the Korean National Health Information Database and medical records including coexisting asthma, AR, and ACD. Single and multiple logistic regression models were created for keloids and each allergic disease. The prevalence of keloids was higher in the AD group than in the control group. Among patients with AD, adolescents and adults had a higher prevalence of keloids than infants and children. The risk of keloids was high with AD alone, and coexisting asthma significantly increased the risk. Similarly, the risk of keloids was higher in AR associated with AD and ACD associated with AD than in AD alone. Thus, among Koreans, patients with AD have a higher risk of keloid development, with coexisting allergic diseases increasing the risk.

Abstract
Semi-correlation specifically assesses the correlation between a binary variable and a continuous variable. Semi-correlations were applied to develop binary models for various endpoints. We applied the semi-correlation to develop models of two kinds of skin sensitization one related to animals (local lymph node assay LLNA) and one to human beings (direct peptide reactivity assay DPRA and/or human cell line activation test h-CLAT). The models refer to binary classification for a two-level strategy: the first level (analysis of all compounds) is used in the format "sensitizer or non-sensitizer", and the second level (only sensitizers) is a further classification in the format "strong or weak sensitizer". The ranges of statistical characteristics of the models depend on the endpoint, LLNA or DPRA/h-CLAT: for the first level, sensitivity: 0.69-0.88, specificity: 0.75-0.89, accuracy: 0.77-0.87, Matthew's correlation coefficient (MCC): 0.54-0.57 and for the second level, sensitivity: 0.70-1.0, specificity: 0.78-0.83, accuracy: 0.77-0.87, MCC: 0.54-0.76. Thus, the described approach can be applied to building up models of the skin sensitization potency.

Targeting the Human β c Receptor Inhibits Contact Dermatitis in a Transgenic Mouse Model. J Invest Dermatol 2021; 142:1103-1113.e11.

Abstract
Allergic contact dermatitis (ACD) is a prevalent and poorly controlled inflammatory disease caused by skin infiltration of T cells and granulocytes. The beta common (βc) cytokines GM-CSF, IL-3, and IL-5 are powerful regulators of granulocyte function that signal through their common receptor subunit βc, a property that has made βc an attractive target to simultaneously inhibit these cytokines. However, the species specificity of βc has precluded testing of inhibitors of human βc in mouse models. To overcome this problem, we developed a human βc receptor transgenic mouse strain with a hematopoietic cell‒specific expression of human βc instead of mouse βc. Human βc receptor transgenic cells responded to mouse GM-CSF and IL-5 but not to IL-3 in vitro and developed tissue pathology and cellular inflammation comparable with those in wild-type mice in a model of ACD. Similarly, Il3-/- mice developed ACD pathology comparable with that of wild-type mice. Importantly, the blocking anti-human βc antibody CSL311 strongly suppressed ear pinna thickening and histopathological changes typical of ACD and reduced accumulation of neutrophils, mast cells, and eosinophils in the skin. These results show that GM-CSF and IL-5 but not IL-3 are major mediators of ACD and define the human βc receptor transgenic mouse as a unique platform to test the inhibitors of βc in vivo.

Abstract
It has been reported that Celtis sinensis Pers. is employed as a folk medicine for the treatment of inflammatory diseases. But the mechanism supporting its use as anti-inflammatory remains unclear. To investigate the anti-inflammatory of Celtis sinensis Pers. ICR mice were provided Celtis sinensis Pers. leaf extract (CLE) at 100, 200 mg/kg after ginkgolic acids (GA) sensitization. Our data showed that CLE and the main flavonoid isovitexin in CLE could ameliorate GA-induced contact dermatitis in mice. Ear swelling, inflammatory cell infiltration and splenomegaly were inhibited significantly by isovitexin, while the weight loss of mice in the isovitexin-treated group was much better than that in the dexamethasone-treated group (positive control drug). It has been reported in previous research that GA-induced inflammation is closely related to the T cell response. Therefore, T cells were the focus of the anti-inflammatory effect of isovitexin in this paper. The in vivo results showed that isovitexin (10, 20 mg/kg) inhibited the expression of proinflammatory cytokines (TNF-α, IFN-γ, IL-2 and IL-17A) in lymph nodes, inhibited the secretion of cytokines into the serum from mice with contact dermatitis and promoted the expression of apoptosis-related proteins. In vitro, isovitexin also induced apoptosis and inhibited proinflammatory cytokine expression in Con A-activated T cells. Further study showed that the MAPK and STAT signaling pathways and the phosphorylation of SHP2 were inhibited by isovitexin. Both molecular docking and biological experiments indicated that SHP2 may be an anti-inflammatory target of isovitexin in T cells. Taken together, isovitexin can serve as a potential natural agent for the treatment or prevention of GA-induced inflammatory problems.

Abstract
BACKGROUND The association of atopic dermatitis (AD) and allergic contact dermatitis has been a matter of considerable uncertainty. Study results range from lack of any association to increased sensitization for multiple allergens, but fail to identify consistent allergen associations. OBJECTIVE We studied a large patch test cohort of patients stratified by their atopic skin diathesis using the Erlangen Atopy Score (EAS), independent of active skin disease. METHODS Retrospective multi-center data analysis from five departments of dermatology in Germany with 4,509 patients. Patients were grouped as "no atopic skin diathesis" (n = 2,165) and "atopic skin diathesis" (n = 1,743), according to EAS. RESULTS Significantly more individuals with atopic skin diathesis showed at least one positive patch test reaction to the baseline series compared to individuals without atopic skin diathesis (49.1 % vs. 38.3 %). In logistic regression analyses, atopic skin diathesis was associated with a significantly higher risk of sensitization to methylchloroisothiazolinone/methylisothiazolinone (OR 2.383) and methylisothiazolinone (OR 1.891), thiuram mix (OR 1.614), as well as nickel (OR 1.530), cobalt (OR 1.683), and chromium (OR 2.089). CONCLUSIONS Atopic skin diathesis proved to be the most important intrinsic risk factor for contact sensitization to few, specific allergens. Past or present AD was a less relevant variable.

Abstract
Dermatitis is a common condition frequently encountered by dermatologists. The diagnosis of dermatitis can be challenging because this condition is often multifactorial, and many skin diseases that can mimic dermatitis should be considered in the differential diagnosis. It is important to recognize and be familiar with these conditions because some of them can represent signs of systemic disease or malignancies and misdiagnosis can lead to mismanagement and adverse outcomes for the patient.

Abstract
Allergic contact dermatitis is a prevalent burdensome condition affecting millions of Americans.

Abstract
Atopic dermatitis (AD), a chronic inflammatory skin condition, negatively affects sexual health in various ways including causing physical discomfort and changes in physical appearance that can lead to low self-confidence. The chronic and debilitating nature of this disease can interfere with the sexual well-being of patients and their partners. This review describes the ways that AD affects sexual health. In addition, we review the impact that partnered relationships and physical intimacy can have on AD and provide practical recommendations for optimizing sexual health in AD patients.
