Abstract
Suppressive effect of bis (3-amino-2-pyridine) diselenide (BAPD) on psychiatric disorders - atopic dermatitis (AD) comorbidity in mice was investigated. To sensitize the animals, 2,4-dinitrochlorobenzene (DNCB) was applied to their dorsal skin on days 1-3. Mice were challenged with DNCB on their ears and dorsal skin on days 14, 17, 20, 23, 26, and 29. BAPD and Dexamethasone were administered to the animals, from days 14-29, and skin severity scores and behavioral tests were determined. Oxidative stress and inflammatory parameters were evaluated on the dorsal skin of mice. Na+, K+-ATPase activity and corticosterone levels were determined in hippocampus/cerebral cortex and plasma of mice, respectively. BAPD improved cutaneous damage, scratching behavior, inflammatory and oxidative stress markers. BAPD showed anxiolytic- and antidepressant-like effects and restored Na+, K+-ATPase activity and corticosterone levels. The present study was performed using female mice due the susceptibility for this disease. But, the evaluation of AD model in male mice would help to verify whether the male gender has the same predisposition to present this pathology. Our data demonstrated the suppressive effect of BAPD on psychiatric disorders - AD comorbidity by regulating inflammatory and oxidative status in mice.

Abstract
Atopic dermatitis (AD) is a heterogeneous systemic inflammatory skin disease associated with dysregulated immune responses, barrier dysfunction and activated sensory nerves. To characterize circulating inflammatory profiles and underlying systemic disease heterogeneity within AD patients, blood samples from adult patients (N = 123) with moderate‐to‐severe AD in a phase 2 study of baricitinib (JAHG) were analysed. Baseline levels of 131 markers were evaluated using high‐throughput and ultrasensitive proteomic platforms, patient clusters were generated based on these peripheral markers. We implemented a novel cluster reproducibility method to validate cluster outcomes within our study and used publicly available AD biomarker data set (73 markers, N = 58 patients) to validate our findings. Cluster reproducibility analysis demonstrated best consistency for 2 clusters by k‐means, reproducibility of this clustering outcome was validated in an independent patient cohort. These unique JAHG patient subgroups either possessed elevated pro‐inflammatory mediators, notably TNFβ, MCP‐3 and IL‐13, among a variety of immune responses (high inflammatory) or lower levels of inflammatory biomarkers (low inflammatory). The high inflammatory subgroup was associated with greater baseline disease severity, demonstrated by greater EASI, SCORAD Index, Itch NRS and DLQI scores, compared with low inflammatory subgroup. African‐American patients were predominantly associated with the high inflammatory subgroup and increased baseline disease severity. In patients with moderate‐to‐severe AD, heterogeneity was identified by the detection of 2 disease subgroups, differential clustering amongst ethnic groups and elevated pro‐inflammatory mediators extending beyond traditional polarized immune responses. Therapeutic strategies targeting multiple pro‐inflammatory cytokines may be needed to address this heterogeneity.

Abstract
Atopic dermatitis (AD) is a chronic and relapsing, inflammatory skin disease characterized by impaired skin barrier function and immune system dysregulation that results in dryness, skin microbiome dysbiosis and intense pruritus. It is highly heterogeneous, and its management is demanding. Patients with AD are at greater risk of comorbidities such as attention-deficit hyperactivity disorder as well as other atopic diseases. Early-onset AD cases typically improve or resolve in late childhood; however, it is proposed that the prevalence of persistent or adult-onset AD is higher than previously thought. Basic therapy consists of emollient application and trigger avoidance, and when insufficient, topical corticosteroids (TCS) are the first-line treatment. However, corticophobia/steroid aversion and TCS side-effects, particularly on sensitive skin areas, lead to low compliance and insufficient disease control. Several long- and short-term randomized controlled and daily practice studies have demonstrated that topical calcineurin inhibitors, such as pimecrolimus, have similar anti-inflammatory effects to low-to-medium strength TCS, reduce pruritus and improve the quality of life of patients. In addition, pimecrolimus does not cause skin atrophy, is steroid-sparing and has a good safety profile, with no evidence for an increased risk of malignancies or skin infections. In general, pimecrolimus cream is well-accepted and well-tolerated, encouraging patient adherence and leading to its use by many physicians as a preferred therapy for children and sensitive skin areas.

Abstract
BACKGROUND Given that common pathophysiological factors play a role in atopic dermatitis (AD) and infertility, we assumed that the 2 conditions might demonstrate an epidemiological association. Large-scale epidemiological data on this topic are lacking. OBJECTIVES The aim of this work was to evaluate the potential association between AD and infertility in a broad community-based population. METHODS A nationwide retrospective cohort study was conducted, analyzing the association between AD and infertility. We compared AD patients diagnosed by a dermatologist between 2002 and 2018 and a matched control group. The study population was subdivided according to age into adults (age ≥18 years) and children (age <18 years), and was further subdivided according to AD severity, classified as either mild or moderate-to-severe according to AD-related drug use and healthcare services utilization. RESULTS The study included 127,150 patients with AD and 127,071 comparison enrollees. AD was associated with a higher prevalence of infertility than that of the control group (1.4 and 1.1%, respectively). The prevalence of infertility, per 1,000 patient-years, was increased in patients with AD compared to that of the control group (2.17 and 1.7, respectively). Multivariate analysis for infertility demonstrated that AD was a key risk factor for infertility in both males and females with mild AD and moderate-to-severe AD. CONCLUSION A significant association between AD and infertility was observed. This association suggests that infertility may be an additional manifestation of AD. Further studies are warranted to evaluate the impact of AD management in the setting of infertility and vice versa.

Abstract
Atopic dermatitis (AD) is an itchy, non-contagious relapsing and chronic inflammatory skin disease that usually develops in early childhood. This pathology is associated with food allergy, allergic asthma, allergic rhinitis and anaphylaxis which may persist in adulthood. The underlying mechanisms of AD (endotypes) are just beginning to be discovered and show a complex interaction of various pathways including skin barrier function and immune deviation. Immune reactions to self-proteins (autoantigens) of the skin have been identified in patients with inflammatory skin diseases, such as chronic spontaneous urticaria, connective tissue disease, pemphigus vulgaris and bullous pemphigoid. IgE antibodies and T cells directed against epitopes of the skin were observed in adult patients with severe and chronic AD as well. This was associated with disease severity and suggests a progression from allergic inflammation to severe autoimmune processes against the skin. IgE-mediated autoimmunity and self-reactive T cells might accelerate the ongoing skin inflammation or might contribute to the relapsing course of the disease. However, to date, the exact mechanisms of IgE-mediated autoimmunity and self-reactive T cells in the pathophysiology of AD are still unclear. The aim of this review is to evaluate the development of (autoreactive) T cells and their response to (auto)antigens, as well as the role of the peripheral tolerance in autoimmunity in the pathophysiology of AD, including the unmet needs and gaps.

Abstract
BACKGROUND Atopic dermatitis (AD) has been a hot research direction of dermatologists for a long time. However, the knowledge structures and theme trends for AD have not yet been studied bibliometrically. OBJECTIVE To investigate the distribution pattern and knowledge structure of AD related literatures in PubMed. METHODS Bibliographic information was generated by the Bibliographic Item Co-Occurrence Matrix Builder (BICOMB). A visual matrix was created by the gCLUTO software. GraphPad Prism 5 software was used to construct a Strategic diagram analysis. Ucinet 6.0 software and NetDraw 2.084 software were used to generate a social network analysis (SNA). RESULTS Among all the extracted MeSH terms and subheadings, 77 MeSH terms/MeSH subheadings with a high-frequency were identified, and hot topics were gathered together into 6 groups. In the strategic diagram, immunology, microbiology, and drug therapy of AD were fully developed. In contrast, prevention, pathology, genetics, metabolism, administration, cost of illness, quality of life therapeutic paradigm, and immunosuppressive agents of AD were considerably immature offering prospective scope for further research. CONCLUSIONS The results may potentially aid in describing an all-round grasp of the current research areas and furnish guidelines for the researchers for beginning new projects.

Abstract
Atopic dermatitis (AD) is a common skin disease during infancy, which imposes a considerable burden on patients, their families, and the society, requiring effective treatment options that result in rapid and sustained symptom relief. Additionally, early treatment may prevent the development of atopic comorbidities by restoring the skin barrier. Currently, topical standard-of-care for AD in infants includes emollients and topical corticosteroids (TCS) to treat and reduce the risk of flares. However, only few have been approved for infants and long-term maintenance therapy with TCS is not indicated due to potential local and systemic side effects, including skin atrophy. Accordingly, the recently updated European guidelines for treatment of AD recommend topical calcineurin inhibitors (TCIs) for long-term use, treatment of sensitive skin areas, and for use in the pediatric population. Evidence on the use of TCIs for infants has almost been exclusively collected for pimecrolimus, with >4000 infants evaluated in clinical trials, consistently confirming that pimecrolimus is a safe and effective treatment for infants with AD. Nevertheless, its use is still restricted in most countries to children above the age of 2 years due to initial and mostly theoretical safety concerns. Based on a careful review of the available evidence of clinical trials, post-marketing surveillance, and epidemiological studies, an Expert Panel of European dermatologists and pediatric allergologists concluded that these safety concerns are no longer valid. Therefore, pimecrolimus offers a safe and effective alternative to TCS in infants aged 3 months and above, and labeling restrictions in this age group are no longer justified.

Abstract
BACKGROUND As an evidence resource for the currently planned European Academy of Allergy and Clinical Immunology (EAACI) clinical practice guideline "systemic treatment of atopic dermatitis (AD)," we critically appraised evidence on systemic treatments for moderate-to-severe AD. METHODS We systematically identified randomized controlled trials (RCTs) investigating the safety and efficacy of systemic treatments for AD up to February 2020. Primary efficacy outcomes were clinical signs, AD symptoms and health-related quality of life. Primary safety outcomes included cumulative incidence rates for (serious) adverse events. Trial quality was assessed applying the Cochrane Risk of Bias Tool 2.0. Meta-analyses were conducted where appropriate. RESULTS 50 RCTs totalling 6681 patients were included. Trial evidence was identified for apremilast, azathioprine (AZA), baricitinib, ciclosporin A (CSA), corticosteroids, dupilumab, interferon-gamma, intravenous immunoglobulins (IVIG), mepolizumab, methotrexate (MTX), omalizumab, upadacitinib and ustekinumab. Meta-analyses were indicated for the efficacy of baricitinib [EASI75 RD 0.16, 95% CI (0.10;0.23)] and dupilumab [EASI75, RD 0.37, 95% CI (0.32;0.42)] indicating short-term (ie 16-week treatment) superiority over placebo. Furthermore, efficacy analyses of AZA and CSA indicated short-term superiority over placebo; however, nonvalidated scores were used and can therefore not be compared to EASI. CONCLUSION The most robust, replicated high-quality trial evidence is present for the efficacy and safety of dupilumab for up to 1 year in adults. Robust trial evidence was further revealed for AZA, baricitinib and CSA. Methodological restrictions led to limited evidence-based conclusions for all other systemic treatments. Head-to-head trials with novel systemic treatments are required to clarify the future role of conventional therapies.

Abstract
Atopic dermatitis (AD) is a chronic inflammatory skin disease with an estimated prevalence of 10-15% in children and 2-10% in adults. Clinically, there is notable phenotypic variability driven by a complex interaction between genetics, immune function, and the environment. Impairment of the skin barrier plays a significant role in the pathogenesis of AD. The apparent beneficial effect of sunlight in patients with atopic eczema is questioned due to its capacity to disrupt the skin barrier and generate free radicals that can damage proteins, lipids, and DNA. The sum of the external factors that an individual is exposed to throughout their lifetime is termed the exposome. Environmental factors such as sun exposure, temperature, and humidity contribute to both AD flares and regional prevalence variation. Literature on photoprotection in atopic dermatitis is very scarce. The use of adequate sunscreens in atopic dermatitis can ensure the level of photoprotection required to prevent skin photoaging and skin cancer and to mitigate skin barrier dysfunction, decrease inflammation, and neutralize facial redness. Herein we discuss and review the role of UV radiation and the exposome in the etiology of AD, as well as the role of adequate photoprotection.

Wollenberg A, Thomsen SF, Lacour JP, Jaumont X, Lazarewicz S. Targeting immunoglobulin E in atopic dermatitis: A review of the existing evidence. World Allergy Organ J 2021; 14:100519. [PMID: 33815652 PMCID: PMC8005850 DOI: 10.1016/j.waojou.2021.100519] [Citation(s) in RCA: 12] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/04/2020] [Revised: 01/04/2021] [Accepted: 01/28/2021] [Indexed: 11/19/2022] Open
Abstract
Immunoglobulin E (IgE) plays an essential role in many allergic diseases. This review highlights the role of IgE in atopic dermatitis (AD), a common, chronic, and complex skin inflammation, and the available therapeutic approaches that target IgE in AD. We examine the existing data showing the use of omalizumab, the only biologic anti-IgE therapy available in clinical use, plasma apheresis, and a combination of both therapeutic approaches for the treatment of AD. Existing data on the efficacy of omalizumab in AD are inconclusive. A limited number of randomised controlled studies, few uncontrolled prospective and retrospective reports, as well as multiple case series and case reports observed varying degrees of the efficacy of omalizumab in AD. Omalizumab displays a trend of higher efficacy in AD patients with low IgE levels compared with those with very high-to-extremely high serum IgE concentrations. Plasma apheresis and its combination with omalizumab show good efficacy, even in patients with unusually high serum IgE concentrations. Combining apheresis and anti-IgE treatment may serve as a comprehensive therapeutic approach for patients with elevated levels of IgE. Dedicated clinical studies with robust study designs are needed to establish the therapeutic efficacy of omalizumab in AD.

Abstract
BACKGROUND Increasing evidence has suggested the systemic nature of atopic dermatitis (AD), a common inflammatory skin condition in children. However, comprehensive analyses of real-world comorbidities in pediatric AD are limited. OBJECTIVE To characterize comorbidity burden in patients with AD aged <18 years old. METHODS The MarketScan commercial claims database was queried from January 1, 2017, to December 31, 2017. Age- and sex-matched analyses were used to compare patients with AD with general population controls. RESULTS A total of 86,969 pediatric patients with AD and 116,564 matched controls were identified. Increased anxiety (odds ratio [OR], 1.20) and attention-deficit hyperactivity disorder (OR, 1.11) were noted in patients with AD. In addition to dermatologic/allergic diseases, AD was also associated with infections, including methicillin-resistant Staphylococcus aureus (OR, 3.76), and autoimmune conditions, including vitiligo (OR, 2.98) and alopecia areata (OR, 4.32). Pediatric patients with AD had higher likelihoods of lymphoid/hematologic malignancies (OR, 1.94), ocular disorders (OR, 1.37-2.02), metabolic syndrome (OR, 1.61), and obesity (OR, 1.81). For all the ORs mentioned above, P was <.001. LIMITATIONS Retrospective analysis of health care claims data. CONCLUSIONS AD in pediatric patients was associated with a wide range of psychologic and systemic comorbidities. Increased awareness can help minimize its negative effects on the quality of life and prevent long-term health consequences in young patients with AD.

Abstract
BACKGROUND Atopic dermatitis (AD) is complex with unmet needs and management challenges in clinical practice. Little is known about patient satisfaction among adults with AD. OBJECTIVE The aim of the study was to determine patterns and predictors of patient satisfaction among adults with AD. METHODS Data were analyzed from the 2000-2015 Medical Expenditure Panel Survey. Patient satisfaction was assessed by the Consumer Assessment of Healthcare Providers and Systems survey. RESULTS Atopic dermatitis (linear regression; adjusted β [95% confidence interval {95% CI}] = -0.75 [-1.25 to -0.25]) was associated with lower patient satisfaction compared with no AD. Adults with 1 or more office-based visits had increased odds of high satisfaction (>75th percentile; logistic regression; adjusted odds ratio [95% CI] = 1.81 [1.30-2.52]). Adults who saw an outpatient dermatologist or allergist had lower satisfaction (adjusted β [95% CI] = -0.65 [-1.27 to -0.03]). Patient satisfaction among adults with AD was associated with older age (adjusted β [95% CI] = 40-59 years, 1.85 [0.90-2.80]; ≥60 years, 6.13 [5.18-7.09]) and inversely associated with lower income (-1.82 [-2.68 to -0.96]) or middle income (-0.85 [-1.59 to -0.12]), race/ethnicity (Hispanic, -1.40 [-2.42 to -0.38]; other/multiracial, -2.34 [-3.53 to -1.15]), public (-4.50 [-6.43 to -2.58]) or no insurance (-4.53 [-6.47 to -2.59]), and multimorbidity (-0.48 [-0.61 to -0.35]). CONCLUSIONS Adults with AD in the United States had decreased patient satisfaction, particularly those with lower income, fewer outpatient visits, and multimorbidity. There are substantial unmet needs in patient satisfaction for AD.

Abstract
Atopic dermatitis (AD) is associated with systemic inflammation and systemic corticosteroid use which can lead to poor bone health. The aim of this systematic review is to investigate the relationship between AD and bone mineral density (BMD), osteoporosis and fractures. We searched Web of Science, Cochrane Database of Systematic Reviews, MEDLINE and Embase. Title, abstract and full-text screening, and data extraction were done in duplicate. Quality appraisal was performed using the Agency for Healthcare Research and Quality Methodology Checklist (cross-sectional studies) and Newcastle-Ottawa Scale (cohort studies). We screened 3800 abstracts and included fifteen studies (twelve cross-sectional, three cohort). In cross-sectional studies, AD was associated with decreased BMD and increased fractures. In cross-sectional studies and a cohort study, AD was associated with a higher prevalence of osteoporosis compared to controls. There was inconsistency across studies, with some finding no association. In a large cohort study, AD was associated with increased risk of fractures of the hip (HR: 1.06, 95% CI: 1.02 to 1.11), spine (HR: 1.14, 95% CI: 1.06 to 1.23) and wrist (HR: 1.06, 95% CI: 1.01 to 1.10), with further increased risk with more severe AD. Differences between studies precluded quantitative synthesis. There is some evidence supporting an association between AD and poor bone health. Research is needed to clarify this association, underlying mechanisms and develop strategies to improve bone health of individuals with AD.

Abstract
BACKGROUND Atopic dermatitis (AD) is the chronic inflammatory disorder that affects both in childhood and adulthood. Mounting evidence indicates that gut dysbiosis contributes to AD via the gut-skin axis. Constipation can result in alteration of the gut microflora. The clinical impact of constipation on AD has not been researched. Therefore, we aim to assess the risk of AD in constipated patients by the population-based cohort study. METHODS We collected 85 554 constipated people and 85 554 people without constipation between 1999 and 2013 from the Taiwanese National Health Insurance Research Database. Propensity score analysis was administrated to match age, gender, comorbidities and medications at a ratio of 1:1. Multiple Cox regression analysis was utilised to evaluate the adjusted hazard ratio of AD. In addition, sensitivity tests and a stratified analysis were conducted. RESULTS The incidence of AD was 4.9 per 1000 person-years in the constipation group, which was higher than the rate of 2.1 per 1000 person-years observed in the non-constipation group. After adjustment for age, gender, comorbidities, corticosteroids, antihistamine and antibiotics, constipated people had a 2.31-fold greater risk of AD compared with those without constipation (adjusted hazard ratio [aHR]: 2.31 (95% CI 2.17-2.46). Moreover, constipated people had a higher likelihood of AD, regardless of gender, comorbidities, as well as the usage of corticosteroids, antihistamines and antibiotics. CONCLUSION Constipation is associated with a significantly risk factor of AD. Clinicians should be careful of the possibility of AD in constipated people. Further study is warranted to investigate the possible pathological mechanisms of this relationship.

Abstract
BACKGROUND Emollients capable of restoring the skin barrier function would extend their role beyond basic maintenance therapy in atopic dermatitis (AD). OBJECTIVES Investigate the effect of a novel emollient plus cream (EC; Dermoflan®) on the skin barrier in vitro and in patients with mild-to-moderate AD. METHODS The effect of EC on the skin barrier recovery was evaluated using a tape-stripping (TS) model. After TS, organ cultures were treated with EC (undiluted or diluted 1:1 with water) and analyzed at 18-120 h using hematoxylin and eosin, Oil Red O, immunohistochemical, and immunofluorescent techniques. In a double-blind, randomized study, EC or placebo was applied once daily for 2 months to antecubital folds of the upper and lower limbs of patients with mild-to-moderate AD in clinical remission. Epidermal thickness, vascularization, and epidermal hydration were assessed by optical coherence tomography and corneometry, respectively, at baseline, and 1 and 2 months following treatment initiation. RESULTS Following TS, EC treatment significantly increased epidermal thickness and lipid content versus diluent in the skin organ culture, as well as claudin-1, involucrin, and caspase-14 expression, suggesting skin barrier repair. EC treatment also decreased keratin-16 expression and increased levels of Toll-like receptors 1 and 2 versus diluent, suggesting involvement in regulating the epidermal immune response. In 20 patients randomized 1:1 to EC or placebo, EC treatment at the elbow fold/popliteal fossa significantly decreased epidermal thickness after 2 months, and the number of blood vessels at the elbow fold after 1 and 2 months, versus placebo. EC significantly improved the skin hydration after 2 months versus baseline. CONCLUSIONS This novel multi-action EC may help to restore epidermal homeostasis and improve the skin of patients with AD. Results indicate that this novel multi-action EC could be a valid adjuvant therapy in patients with AD. Key Message: Novel multi-action emollient cream helps to restore epidermal homeostasis and improves the skin affected by AD.

Abstract
This article has been co-authored by a patient with atopic dermatitis (AD) and her consulting dermatologist who is based at the University Hospital in Angers, France. Here they discuss the patient’s experiences and difficulties with AD, as well as strategies that can help a patient in this situation. The patient describes the history of her illness and the difficulties encountered, particularly in terms of quality of life. She describes the various treatments she has received, mainly based on topical corticosteroids, and tells of her satisfaction at being treated today at the University Hospital. The healthcare team there is supportive and reassuring and she is receiving a systemic medication that has successfully reduced and controlled her AD symptoms. The physician describes the main characteristics of AD, and then reviews this case of chronic eczema with topographical localisations on the hands, head and neck and diffuse flares. Rapid resolution of the flares on the patient’s hands and face, which were having a strong impact on mood, was achieved by treatment with systemic ciclosporin and topical corticosteroids. In 6 months, treatment with dupilumab will be planned to avoid ciclosporin-induced adverse effects on kidney function. The pivotal roles of therapeutic education as an adjunct to conventional therapy, a good patient–physician relationship with consideration of the patient’s personal preferences, and treatment objectives are highlighted in this perspective piece. This article has been co-authored by a French patient who has had atopic dermatitis (eczema, AD) since childhood and her dermatologist, a French healthcare professional based in a university hospital in Angers. AD is caused by a genetic variation that affects the skin’s ability to protect against bacteria, irritants and allergens. In people with AD, environmental factors make the skin red and itchy. AD can occur at any age; it most often begins before 5 years of age and may persist into adolescence and adulthood. AD signs and symptoms vary widely, and the disease may be accompanied by asthma and allergies. AD is long lasting (chronic) and, even if treatment is successful, signs and symptoms may return (flare) periodically. The patient describes her personal experience, including how the discomfort from the AD on her face and hands affected her daily activities and sleep. She talks about having to try various treatments, including home remedies, over the years to control AD and relates her frustration when experiencing symptoms. Now she is being monitored by a healthcare team in a French university hospital that gives her full care and support. As a result, she is now receiving a systemic medication that reduces and controls the AD symptoms and she is very satisfied with her care. The dermatologist notes that this patient’s experience is a common clinical picture of AD in adults, and discusses how the patient was treated and how the treatment will evolve over time. The dermatologist emphasises the importance of a good patient–physician relationship for successful AD management. This should be based on confidence and empathy, and consider the patient’s expectations, personal preferences and treatment objectives. Therapeutic education (educational programs, video training and workshops) is pivotal as an adjunct to conventional therapy.

Abstract
The Continuum theory and the Levels of Health theory propound the idea that return of efficient acute inflammation (high fever) heralds true improvement in chronic inflammatory states. We present 6 cases of atopic dermatitis (AD), which had stability in their improvement for 1 year or more, under classical homeopathy. The cases were retrospectively assessed with selected based on the Hanifin Rajka atopic dermatitis diagnostic criteria and the follow ups evaluated according to changes on SCORing Atopic Dermatitis scale (SCORAD) scale. The pictures are presented as evidence. Modified Naranjo Criteria for assessing causal attribution of clinical outcome to homeopathic intervention was used to assess the effect of homeopathy in these cases. All the cases improved and stabilised with complete skin clearance (those that relapsed within 1 year were not included). These patients had not suffered high fevers/acute inflammatory diseases since onset/aggravation of AD. Five of the 6 cases developed acute inflammatory diseases as the chronic condition improved. The last case showed return of an old, lesser pathology. The control cases – which were selected for non-improvement under classical homeopathy also showed remarkable skin clearance when there was appearance of acute inflammatory states. In this study, there is a mutually exclusive relationship between efficient acute inflammation and chronic inflammation, which is in accordance with the 2 theories considered here. Further scientific studies are necessary to establish the phenomenon at tissue level.

Abstract
Dr Anne-Claire Fougerousse is Head of Dermatology at the Bégin Hospital in Saint-Mandé, France, and scientific coordinator of a French network of dermatologists and allergists (ResoEczema). The focus of her work is to improve the care of adolescent and adult patients with atopic dermatitis (AD), a chronic, pruritic inflammatory skin disease that substantially impacts patient quality of life. In this interview, Dr Fougerousse provides an overview of the clinical presentation of adult patients with AD and describes available treatments. Today, topical agents like emollients and corticosteroids are the mainstay of AD therapy, and patients with lesions that are resistant to optimally administered topical treatment can also receive phototherapy or systemic therapy with ciclosporin. Dr Fougerousse discusses her hopes for the future of AD therapy with the recent development of biologicals like dupilumab, which may provide improvements in clinical outcomes and quality of life for patients with moderate-to-severe AD. In the next few years, the therapeutic arsenal for AD will likely expand to include more systemic therapies providing sustained symptom control. The real challenge will be to ensure that the maximum number of patients with AD achieve clinical benefits from these new treatments.

Abstract
Introduction Atopic dermatitis (AD) is a chronic inflammatory disorder which, despite recent therapeutic developments, leads to significant burden and morbidity, impacting on daily functioning, physical and mental health, and health-related quality of life. The objective of this study was to investigate the impact of new therapeutic approaches in the treatment of moderate to severe AD and quantify subsequent differences in disease and symptom control. Methods Data were drawn from the 2018 Adelphi US AD Disease Specific Programme™ (DSP™), a cross-sectional survey of physicians (n = 150) and their patients with a history of moderate to severe AD (n = 749, 52.7% female, 72.1% white, mean age 40.1 ± 16.3 years). Inadequately controlled AD as rated by the physician was defined as currently flaring, and/or deteriorating/changeable AD and/or physician dissatisfaction with disease control on current treatment. Results The overall inadequate control rate was 42.3%, an improvement from 58.7% as identified in the 2014 DSP survey. The proportion of inadequately controlled patients increased as physician subjective severity (ranked from mild through to severe) increased; 15.4% of patients classified as having mild disease were inadequately controlled, compared to 94.5% of patients classified with severe disease. Relative to patients with controlled disease, patients with inadequately controlled disease were more likely to be unemployed, reported more frequent flares, and had a greater burden of symptoms and worse quality of life measures including itch, stress, anxiety, depression, and sleep disturbance (all p < 0.0001). Conclusion Despite the introduction of new therapies, the burden and impact of AD and lack of symptom control, although reduced compared with previous studies, still remains high.

Abstract
Therapeutic options for autoimmune diseases typically consist of broad and targeted immunosuppressive agents. However, sustained clinical benefit is rarely achieved, as the disease phenotype usually returns after cessation of treatment. To better understand tissue-resident immune memory in human disease, we investigated patients with atopic dermatitis (AD) who underwent short-term or long-term treatment with the IL-4Rα blocker dupilumab. Using multi-omics profiling with single-cell RNA sequencing and multiplex proteomics, we found significant decreases in overall skin immune cell counts and normalization of transcriptomic dysregulation in keratinocytes consistent with clearance of disease. However, we identified specific immune cell populations that persisted for up to a year after clinical remission while being absent from healthy controls. These populations included LAMP3 + CCL22+ mature dendritic cells, CRTH2 + CD161 + T helper ("TH2A") cells, and CRTAM + cytotoxic T cells, which expressed high levels of CCL17 (dendritic cells) and IL13 (T cells). TH2A cells showed a characteristic cytokine receptor constellation with IL17RB, IL1RL1 (ST2), and CRLF2 expression, suggesting that these cells are key responders to the AD-typical epidermal alarmins IL-25, IL-33, and TSLP, respectively. We thus identified disease-linked immune cell populations in resolved AD indicative of a persisting disease memory, facilitating a rapid response system of epidermal-dermal cross-talk between keratinocytes, dendritic cells, and T cells. This observation may help to explain the disease recurrence upon termination of immunosuppressive treatments in AD, and it identifies potential disease memory-linked cell types that may be targeted to achieve a more sustained therapeutic response.

Abstract
Atopic dermatitis (AD) is a prevalent inflammatory skin disease. IL-13 contributes significantly to the pathogenesis of AD in several ways, and beneficial results have been demonstrated with anti-IL-13 therapies. Currently, the only monoclonal antibody (mAb) approved for AD treatment is dupilumab, an antagonist of the IL-4 receptor alpha (IL-4Rα) subunit common to IL-4 and IL-13 receptors, but clinical trials evaluating anti-IL-13 mAbs are providing promising results. The topics of this review will be mAbs targeting IL-13 for the treatment of AD such as dupilumab, tralokinumab and lebrikizumab, small molecules targeting the IL-13 pathway, and a brief explanation of therapies targeting IL-13 for the treatment of other skin diseases.

Abstract
BACKGROUND Atopic dermatitis (AD) is associated with altered skin barrier, microbiome, and immune dysregulation that may increase risk of skin infections. OBJECTIVE The aim of the study was to determine whether AD is associated with skin infections and related outcomes. METHODS Data from the 2006 to 2012 National Emergency Department Sample were analyzed, including an approximately 20% sample of all US emergency department (ED) visits (N = 198,102,435 adults or children). RESULTS Skin infections were increased in ED visits of adults (7.14% vs 3.76%) and children (5.15% vs 2.48%) with AD. In multivariable logistic regression models, AD was associated with significantly higher odds of skin infection in adults (adjusted odds ratio [95% confidence interval] = 1.93 [1.89-1.97]) and children (2.23 [2.16-2.31]). Pediatric and adult AD were associated with significantly higher odds of carbuncle/furuncles, impetigo, cellulitis, erysipelas, methicillin-resistant and methicillin-sensitive Staphylococcus aureus infections, molluscum contagiosum, cutaneous warts, herpes simplex and zoster viruses, eczema herpeticum, dermatophytosis, and candidiasis of skin/nails and vulva/urogenitals. Adults with AD had significantly higher odds of genital warts (1.51 [1.36-1.52]) and herpes (1.23 [1.11-1.35]). Skin infections were associated with US $19 million excess annual costs of ED care in persons with AD. CONCLUSIONS Atopic dermatitis patients had higher odds of multiple bacterial, viral, fungal, and sexually transmitted skin infections.

Abstract
We identified the first-generation antihistamine hydroxyzine as the earliest and most frequently prescribed drug affecting the central nervous system in children under the age of 5 years in the province of British Columbia, Canada (1. 1% prevalence). Whereas, the antagonism of H1-receptors exerts anti-pruritic effects in atopic dermatitis and diaper rash, animal studies suggest an adverse association between reduced neurotransmission of histamine and psychomotor behavior. In order to investigate hydroxyzine safety, we characterized the longitudinal patterns of hydroxyzine use in children under the age of 5 years and determined mental- and psychomotor disorders up to the age of 10 years. We found significantly higher rates of ICD-9 and ICD-10 codes for disorders such as tics (307), anxiety (300) and disturbance of conduct (312) in frequent users of hydroxyzine. Specifically, repeat prescriptions of hydroxyzine compared to a single prescription show an increase in tic disorder, anxiety and disturbance of conduct by odds ratios of: 1.55 (95%CI: 1.23-1.96); 1.34 (95%CI: 1.05-1.70); and 1.34 (95%CI: 1.08-1.66) respectively in children up to the age of 10 years. Furthermore, a non-significant increased trend was found for ADHD (314) and disturbance of emotions (313). This is the first study reporting an association between long-term neurodevelopmental adverse effects and early use of hydroxyzine. Controlled studies are required in order to prove a causal relationship and to confirm the safety of hydroxyzine in the pediatric population. For the time being, we suggest the shortest possible duration for hydroxyzine use in preschool-age children.

Abstract
BACKGROUND The coexistence of hidradenitis suppurativa (HS) and atopic dermatitis (AD) had been reported but, to our knowledge, was not investigated in controlled studies. OBJECTIVE To evaluate the bidirectional association between HS and AD. METHODS A population-based retrospective cohort study was conducted to compare the incidence rate of AD among patients with HS (n = 6779) and age-, sex-, and ethnicity-matched control individuals (n = 33,260). Adjusted hazard ratios (HRs) and adjusted odds ratios were estimated. RESULTS The incidence of AD was 2.51 (95% confidence interval [CI], 2.07-3.02) and 1.24 (95% CI, 1.10-1.40) per 1000 person-years among patients with HS and control individuals, respectively. Patients with HS were twice as likely to develop AD as control individuals (HR, 2.06; 95% CI, 1.64-2.58). Furthermore, the prevalence of pre-existing AD was higher in patients with HS than in control individuals (2.5% vs 1.8%, respectively; P < .001). A history of AD was associated with a 40% increase in the odds of HS (odds ratio, 1.41; 95% CI, 1.19-1.67). Relative to patients with isolated HS, those with a dual diagnosis of HS and AD were younger and had a female predominance, lower prevalence of smoking, and lower body mass index. LIMITATIONS Retrospective data collection. CONCLUSIONS A bidirectional association between HS and AD was observed. Dermatologists should be aware of this association.

Abstract
Introduction Atopic dermatitis (AD) is a chronic, relapsing inflammatory skin condition characterized by pruritic, eczematous lesions. Recent evidence suggests that AD may be a systemic disorder, implying that management of this disease extends beyond merely controlling symptoms associated with AD. Even though this disease is highly prevalent in children and patients typically present with mild-to-moderate symptoms, the disease burden is not well established. Methods A large, retrospective cohort study of Swedish population data was conducted to compare the clinical burden in terms of healthcare resource use and direct medical costs for pediatric mild-to-moderate (pM2M) AD patients (≤ 14 years of age, N = 87,721) with matched controls. The burden of a severe AD cohort was also evaluated. Severity of AD was defined by treatment usage and systemic treatment was used as a proxy for severe AD. A robust approach was used by including any type of secondary care visits known to be more common in AD patients than in the general population; however, data for primary care visits were not available. Results For healthcare resource use, the incidence rate ratio (pM2M AD versus reference cohort) of secondary care visits ranged from 1.56 to 2.35 during each of 5 years after AD onset (all p < 0.001), with largest differences seen in years 1–2. The average direct medical cost (SD) was €1111 (3416) and €524 (2446) in the pM2M AD and reference cohorts, respectively. The corresponding estimate in the severe AD cohort was €1906 (7067). Including all secondary care visits and pharmacy-dispensed medications, the pM2M AD cohort was shown to have an additional €118.9 million in direct medical costs over 5 years compared with the reference cohort. Conclusions This study shows significant clinical and economic burden of pM2M AD with important secondary care resource utilization, suggesting a need for further research to increase treatment options and improve the management of these patients.

Abstract
Background The objective of this study was to investigate the relationships between atopic dermatitis (AD) and other common chronic health conditions in adults. Methods A cross-sectional survey was sent to a randomly selected population sample of 78,004 adults in Sweden. The questionnaires included measures of self-reported physical and mental health. Binary and multinomial logistic regression were used to examine the associations of AD with common chronic health conditions and psychological wellbeing. Results AD was self-reported by 4,175 respondents, representing almost 14% of the study population of 34,313 adults. Our results showed positive associations between AD and chronic health disorders, including conditions of the oral cavity: chronic obstructive pulmonary disease (adjusted odds ratio [aOR] = 1.58, 95% confidence interval [CI]: 1.30 to 1.92), asthma (aOR = 2.13, 95% CI: 1.91 to 2.38), mild recurrent gastrointestinal symptoms (adjusted relative risk ratio [aRRR] = 1.78, 95% CI: 1.64 to 1.92), high blood pressure (aOR = 1.16, 95% CI: 1.06 to 1.26), obesity (aOR = 1.34, 95% CI: 1.23 to 1.47), mild joint pain (aRRR = 1.47, 95% CI: 1.35 to 1.61), mild headache or migraine (aRRR = 1.50, 95% CI: 1.38 to 1.64), caries (aOR = 1.25, 95% CI: 1.04 to 1.49), bleeding gums (aOR = 1.69, 95% CI: 1.38 to 2.08), periodontitis (aOR = 1.42, 95% CI: 1.13 to 1.77), sensitive teeth (aOR = 1.57, 95% CI: 1.35 to 1.82), and dry mouth (aOR = 1.52, 95% CI: 1.33 to 1.74). Adjustment for asthma and depression attenuated the magnitude of the associations between AD and the study outcomes. AD was also associated with poorer general psychological wellbeing. Conclusions Adults reporting AD may be at increased risk of chronic disorders and decreased psychological wellbeing. Physicians should recognize that individuals with severe AD and those with comorbid asthma or depression may be especially vulnerable.

Abstract
Atopic dermatitis (AD) is a chronic inflammatory disease that may be associated with a number of comorbidities including psychosocial disorders, which are the primary focus of this article. The data presented is based on a literature search in PubMed and subsequent screening of relevant review articles and guidelines. There is a greater prevalence of depression, anxiety, sleep disorders and suicidal ideation among individuals with AD. The disease negatively impacts patients' quality of life. Children with AD have been shown to more commonly exhibit signs of attention-deficit/hyperactivity disorder. Only little data exists on the association of AD with schizophrenia, eating disorders or obsessive-compulsive disorder. There is a great need for research in the field of AD-related comorbidities, especially with respect to the question as to whether and how novel treatment options may potentially affect these comorbidities.

Abstract
Introduction Numerous population-based studies have focused on the global prevalence of atopic dermatitis (AD), but there are few studies on the global trends of the burden associated with AD. Methods We analyzed the global AD trends in 2017 in 195 countries worldwide using the Global Burden of Disease (GBD) Study database, including prevalence rates, age and sex patterns, and AD burden, using disability-adjusted life years (DALYs). Age-standardized DALYs were also compared to the sociodemographic index values of all the countries in 2017. Results The age-specific DALYs in 2017 showed a right-skewed distribution, with the highest DALYs between 1 and 5 years of age. Females had a higher burden of AD throughout all age groups and geographic regions. The GBD super region with the greatest burden of DALYs caused by AD was high income (178.63 DALYs per 100,000 males, 231.8 for females), and the country with the highest DALYs was Sweden (326.91). The GBD super region with the lowest age-standardized DALY burden caused by AD was south Asia (84.51 DALYs per 100,000 males, 100.54 for females). Conclusion There is a large GBD caused by AD. The observed burden is the greatest in resource-rich countries, females, and young children.

Abstract
INTRODUCTION As new topical and systemic treatments become available for atopic dermatitis (AD), there is a need to understand how treatments are being used in routine clinical practice, their comparative effectiveness and their long-term safety in diverse clinical settings. METHODS AND ANALYSIS The TARGET-DERM AD cohort is a longitudinal, observational study of patients with AD of all ages, designed to provide practical information on long-term effectiveness and safety unobtainable in traditional registration trials. Patients with physician-diagnosed AD receiving prescription treatment (topical or systemic) will be enrolled at academic and community clinical centres. Up to 3 years of retrospective medical records, 5 years of prospective medical records, and optional biological samples and patient-reported outcomes will be collected. The primary aims include characterisation of AD treatment regimens, evaluation of response to therapy, and description of adverse events. ETHICS AND DISSEMINATION TARGET-DERM has been approved by a central IRB (Copernicus Group IRB, 5000 Centregreen Way Suite 200, Cary, North Carolina 27513) as well as local and institutional IRBs. No additional Ethics Committee reviews. Results will be reviewed by a publications committee and submitted to peer-reviewed journals. TRIAL REGISTRATION NUMBER NCT03661866, pre-results.

Abstract
Atopic dermatitis is a persistent inflammatory skin disorder. Siraitia grosvenorii fruits (monk fruit or nahangwa in Korean, NHG) are used as a natural sweetener and as a traditional medicine for the treatment of asthma and bronchitis. We evaluated the activity of S. grosvenorii residual extract (NHGR) on allergic inflammation of atopic dermatitis in a Dermatophagoides farinae mite antigen extract (DfE)-treated NC/Nga murine model and in vitro. Oral administration of NHGR significantly reduced epidermal hyperplasia and inflammatory cell infiltration in the skin lesions of DfE-induced atopic dermatitis, as well as the dermatitis severity score. NHGR reduced serum immunoglobulin E levels. Splenic concentrations of IFN-γ, interleukin (IL)-4, IL-5, and IL-13 were reduced by NHGR administration. Immunohistofluorescence staining showed that NHGR administration increased the protein levels of claudin-1, SIRT1, and filaggrin in atopic dermatitis skin lesions. In addition, NHGR inhibited the phosphorylation of mitogen-activated protein kinases and decreased filaggrin and chemokine protein expression in TNF-α/IFN-γ-induced human keratinocytes. Moreover, NHGR also inhibited histamine in mast cells. The quantitative analysis of NHGR revealed the presence of grosvenorine, kaempferitrin, and mogrosides. These results demonstrate that NHGR may be an efficient therapeutic agent for the treatment of atopic dermatitis.

To inspect if individualized classical homeopathy has a role in treating complaints after surgical menopause through real world case, we present a case of a 54-year-old Russian woman treated with individualized classical homeopathy for multimorbid conditions after surgical menopause examined for changes from homeopathic treatment. We assessed changes in climacteric symptoms, changes in comorbidities, and the general well-being of the patient. The woman had severe climacteric syndrome, pelvic inflammatory disease, dyslipidemia, obesity, hepatic steatosis, pancreatic lipomatosis, gall bladder disease, and mild subclinical hypothyroidism to begin with. She was treated with individualized classical homeopathy and followed up for 31 months. She was relieved of the vasomotor symptoms and psychological disturbances of climacteric syndrome, her weight reduced, the ultrasound scan showed absence of lipomatosis/gall bladder disease/hepatic steatosis. Blood tests showed reduction of thyroid stimulating hormone and a balance in the lipid status. Individualized classical homeopathy may have a role in the climacteric syndrome and comorbidities after surgical menopause. The efficacy of homeopathic therapy in climacteric problems must be scientifically investigated further.

Abstract
Importance Adolescents with atopic dermatitis (AD) have high disease burden negatively affecting quality of life, with limited treatment options. The efficacy and safety of dupilumab, a monoclonal antibody, approved for treatment in adolescent patients with inadequately controlled AD, remain unknown in this patient population. Objective To assess the efficacy and safety of dupilumab monotherapy in adolescents with moderate to severe inadequately controlled AD. Design, Setting, and Participants A randomized, double-blind, parallel-group, phase 3 clinical trial was conducted at 45 US and Canadian centers between March 21, 2017, and June 5, 2018. A total of 251 adolescents with moderate to severe AD inadequately controlled by topical medications or for whom topical therapy was inadvisable were included. Interventions Patients were randomized (1:1:1; interactive-response system; stratified by severity and body weight) to 16-week treatment with dupilumab, 200 mg (n = 43; baseline weight <60 kg), or dupilumab, 300 mg (n = 39; baseline weight ≥60 kg), every 2 weeks; dupilumab, 300 mg, every 4 weeks (n = 84); or placebo (n = 85). Main Outcomes and Measures Proportion of patients with 75% or more improvement from baseline in Eczema Area and Severity Index (EASI-75) (scores range from 0 to 72, with higher scores indicating greater severity) and Investigator's Global Assessment (IGA) 0 or 1 on a 5-point scale (scores range from 0 to 4, with higher scores indicating greater severity) at week 16. Results A total of 251 patients were randomized (mean [SD] age, 14.5 [1.7] years; 148 [59.0%] male). Of 250 patients with data available on concurrent allergic conditions, most had comorbid type 2 diseases (asthma, 134 [53.6%]; food allergies, 60.8%; allergic rhinitis, 65.6%). A total of 240 patients (95.6%) completed the study. Dupilumab achieved both coprimary end points at week 16. The proportion of patients with EASI-75 improvement from baseline increased (every 2 weeks, 41.5%; every 4 weeks, 38.1%; placebo, 8.2%) with differences vs placebo of 33.2% (95% CI, 21.1%-45.4%) for every 2 weeks and 29.9% (95% CI, 17.9%-41.8%) for every 4 weeks (P < .001). Efficacy of the every-2-week regimen was generally superior to the every-4-week regimen. Patients in the dupilumab arms had higher percentage values of conjunctivitis (every 2 weeks, 9.8%; every 4 weeks, 10.8%; placebo, 4.7%) and injection-site reactions (every 2 weeks, 8.5%; every 4 weeks, 6.0%; placebo, 3.5%), and lower nonherpetic skin infections (every 2 weeks, 9.8%; every 4 weeks, 9.6%; placebo, 18.8%). Conclusions and Relevance In this study, dupilumab significantly improved AD signs, symptoms, and quality of life in adolescents with moderate to severe AD, with an acceptable safety profile. Placebo-corrected efficacy and safety of dupilumab were similar in adolescents and adults. Trial Registration ClinicalTrials.gov identifier: NCT03054428.

van Os-Medendorp H, Deprez E, Maes N, Ryan S, Jackson K, Winders T, De Raeve L, De Cuyper C, Ersser S. The role of the nurse in the care and management of patients with atopic dermatitis. BMC Nurs 2020; 19:102. [PMID: 33292229 PMCID: PMC7640616 DOI: 10.1186/s12912-020-00494-y] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/24/2019] [Accepted: 10/20/2020] [Indexed: 12/20/2022] Open
Abstract
BACKGROUND The purpose of this paper is to provide an overview of key aspects of specialised dermatology nursing practice in the management of patients with moderate to severe atopic dermatitis. The role of dermatology nurse specialists in supporting patients and promoting disease understanding, education and treatment adherence continues to evolve. As features of specialised nursing care can also inform other nursing staff in a wide range of care settings, an overview of key components is examined. Observations presented are from a pan-European perspective and represent the collected view of a group of dermatology nurse specialists, dermatologists and patient advocates following two round-table discussions. MAIN BODY Atopic dermatitis is a common, chronic, inflammatory disease characterised by erythematous/scaling skin lesions, with often intense pruritus. Disease course is cyclic with periodic disease flares of varying intensity, presenting management challenges to patients and families. Dermatology nurse specialists play a key role in providing education and substantial patient support to improve treatment outcomes and quality of life to patients and their family, delivered within a multidisciplinary team framework. Nurse-led education and 'eczema schools' are of benefit in reducing disease severity and improving quality of life by enhancing self-management, adherence and patient engagement. eHealth tools, such as patient portals or online training platforms, can provide online learning, individualised education, and help to improve engagement. These and other initiatives, such as written action plans, are all essential to improve or maintain treatment adherence, self-management and quality of life. CONCLUSIONS Dermatology nurse specialists play a central role in the assessment and management of moderate to severe atopic dermatitis patients and families. This places them in an ideal position to build strong and often long-term relationships with patients and parents. Such engagement promotes trust, assists in setting realistic expectations of treatment and outcomes, and enhances self-management and engagement in their own care. Providing emotional support, as well as formal and systematic education (including individualised practical advice) all contribute to improved treatment adherence and can enhance the quality of life of patients and their families throughout the course of this long-term condition.

Abstract
Background Atopic dermatitis (AD) is a common chronic skin disorder and is well known to be associated with other atopic conditions. There is increasing evidence for an association also with nonatopic conditions, including autoimmune diseases, but data are limited about several autoimmune diagnoses. Objectives To investigate the association between AD and autoimmune diseases. Methods This case–control study used Swedish national healthcare registers. The source population comprised the entire Swedish population aged ≥ 15 years from 1968 to 2016. Cases, including all those with an inpatient diagnosis of AD (from 1968) and/or a specialist outpatient diagnosis of AD (from 2001), were matched by sex and age to healthy controls (104 832 cases of AD, 1 022 435 controls). Results AD was significantly associated with one or more autoimmune diseases compared with controls – adjusted odds ratio (aOR) 1·97, 95% confidence interval (CI) 1·93–2·01 – and this association was significantly stronger in the presence of multiple autoimmune diseases compared with only one. The association was strongest for autoimmune disorders involving the skin (aOR 3·10, 95% CI 3·02–3·18), the gastrointestinal tract (aOR 1·75, 95% CI 1·69–1·82) or connective tissue (aOR 1·50, 95% CI 1·42–1·58). In the overall analysis, men with AD had a stronger association with rheumatoid arthritis and coeliac disease than did women with AD. In subanalyses, the findings remained stable in multivariable analyses after adjustment for smoking and parental autoimmune disease. Conclusions This large population‐based study indicates significant autoimmune comorbidity of adults with AD, especially between AD and autoimmune dermatological, gastrointestinal and rheumatological diseases. Having multiple autoimmune diseases resulted in a stronger association with AD than having only one autoimmune disease.
What is already known about this topic?
Atopic dermatitis (AD) is one of the most common chronic inflammatory skin diseases. Some studies have shown that AD is associated with some autoimmune diseases, such as Crohn disease, ulcerative colitis, coeliac disease, alopecia areata and vitiligo, but data are limited for several major autoimmune diagnoses.
What does this study add?
In this study, AD was associated with several autoimmune diseases, especially those involving the skin, the gastrointestinal tract or connective tissue. The association was stronger for individuals with multiple autoimmune comorbidities.

Abstract
BACKGROUND Atopic dermatitis (AD) is a common skin disease affecting up to 20% of the global population, with significant clinical heterogeneity and limited information about molecular subtypes and actionable biomarkers. Although alterations in the skin microbiome have been described in subjects with AD during progression to flare state, the prognostic value of baseline microbiome configurations has not been explored. OBJECTIVE Our aim was to identify microbial signatures on AD skin that are predictive of disease fate. METHODS Nonlesional skin of patients with AD and healthy control subjects were sampled at 2 time points separated by at least 4 weeks. Using whole metagenome analysis of skin microbiomes of patients with AD and control subjects (n = 49 and 189 samples), we identified distinct microbiome configurations (dermotypes A and B). Blood was collected for immunophenotyping, and skin surface samples were analyzed for correlations with natural moisturizing factors and antimicrobial peptides. RESULTS Dermotypes were robust and validated across 2 additional cohorts (63 individuals), with strong enrichment of subjects with AD in dermotype B. Dermotype B was characterized by reduced microbial richness, depletion of Cutibacterium acnes, Dermacoccus and Methylobacterium species, individual-specific outlier abundance of Staphylococcus species (eg, S epidermidis, S capitis, S aureus), and enrichment in metabolic pathways (eg, branched chain amino acids and arginine biosynthesis) and virulence genes (eg, β-toxin, δ-toxin) that defined a pathogenic ecology. Skin surface and circulating host biomarkers exhibited a distinct microbial-associated signature that was further reflected in more severe itching, frequent flares, and increased disease severity in patients harboring the dermotype B microbiome. CONCLUSION We report distinct clusters of microbial profiles that delineate the role of microbiome configurations in AD heterogeneity, highlight a mechanism for ongoing inflammation, and provide prognostic utility toward microbiome-based disease stratification.

Pooled safety analysis of baricitinib in adult patients with atopic dermatitis from 8 randomized clinical trials. J Eur Acad Dermatol Venereol 2020; 35:476-485. [PMID: 32926462 DOI: 10.1111/jdv.16948] [Citation(s) in RCA: 81] [Impact Index Per Article: 20.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/10/2020] [Accepted: 09/07/2020] [Indexed: 12/14/2022]
Abstract
BACKGROUND Janus kinase (JAK) inhibition is a new mode of action in atopic dermatitis (AD); clarity about drug class safety considerations in the context of AD is important. Baricitinib, an oral, reversible, selective inhibitor of JAK1/JAK2, is in late-stage development for adult patients with moderate-to-severe AD. OBJECTIVE To report pooled safety data for baricitinib in patients with moderate-to-severe AD in the clinical development program including long-term extension (LTE) studies. METHODS This analysis included patient-level safety data from six double-blinded, randomized, placebo-controlled studies (one phase 2 and five phase 3), one double-blinded, randomized, LTE study and one open-label LTE study, reported in three data sets: placebo-controlled, 2-mg - 4-mg extended and All-bari AD. Safety outcomes include treatment-emergent adverse events, adverse events of special interest and abnormal laboratory changes. Proportions of patients with events and incidence rates were calculated. RESULTS Data were collected for 2531 patients who were given baricitinib for 2247 patient-years (median duration 310 days). The frequency of serious infections, opportunistic infections and conjunctival disorders was low and similar between treatment groups in the placebo-controlled period. The most common serious infections were eczema herpeticum [n = 11, incidence rates (IR) = 0.5], cellulitis (n = 6, IR = 0.3) and pneumonia (n = 3, IR = 0.1). There were four opportunistic infections (IR = 0.2). No malignancies, gastrointestinal perforations, positively adjudicated cardiovascular events or tuberculosis were reported in the placebo-controlled period in baricitinib-treated patients. Frequency of herpes simplex was higher in the 4-mg group (6.1%) vs. the 2-mg (3.6%) and placebo group (2.7%); IRs in the extended data set (2-mg IR = 9.6; 4-mg IR = 14.5) were lower vs. the placebo-controlled data set (2-mg IR = 12.4; 4-mg IR = 21.3). In the All-bari AD data set, there were two positively adjudicated major adverse cardiovascular events (2-mg group): two venous thrombosis events (4-mg group) and one death. CONCLUSION This integrated safety analysis in patients with moderate-to-severe AD confirms the established safety profile of baricitinib.

[PMID: 32993599 PMCID: PMC7526254 DOI: 10.1186/s12895-020-00107-w] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 10/04/2019] [Accepted: 09/20/2020] [Indexed: 11/14/2022]
Abstract
Background Chronic illnesses belong to suicide risk factors. The goal of the current study was to estimate the rate of suicide-related behaviors in patients with atopic dermatitis, psoriasis, or acne from a third-person perspective (namely, Austrian dermatologists). Methods A link to a questionnaire specially developed for this study was emailed to 450 self-employed dermatologists in Austria, from which a total of 45 participated. Results Three dermatologists reported more than five patients with atopic dermatitis, psoriasis, or acne who committed suicide in 2017. Seven doctors treated between 1 and 10 such patients suffering from suicidal ideation. These results are suggestive for a low rate of suicidal ideations in Austrian dermatology ordinations. The majority of dermatologists in the sample (82%) knew that these patients are at higher suicide risk. 60% of participants also believed that it rather would not be a problem for them to recognize suicidal ideation. When facing patients in a suicide crisis, reported intervention steps were: referring them to a specialist in psychiatry, or having a conversation about it. In the sample, most challenging about suicide was lack of time and lack of knowledge. Dermatologists were also interested in cooperating with mental health professionals and in the implementation of new prevention strategies (e.g., suicide-related training programs). Analysis revealed that private specialists, as compared with contract physicians, had fewer patients, but spent more time with them. Yet, these differences did not appear to influence the quality of treatment they provided. Treatment quality was defined as the extent to which doctors tell their patients that additional psychological treatments could be helpful and asking them about their emotional state. Female gender and a professional background in psychology impacted positively on treatment quality. Conclusions Possible explanations for the low rate of suicidal ideations reported include the advanced Austrian health care system and dermatologists’ underestimation of the problem. Implications of the study are to promote cooperation between dermatologists and mental health professionals and to address patient suicidality from a first-person perspective (i.e., the patients).

Abstract
BACKGROUND Allergic rhinitis (AR), atopic dermatitis (AD), and asthma, each by itself, are known to be associated with a higher risk of cardiovascular disease. Each of these diseases often coexists with one another, but the effect of combined allergic diseases on the long-term risk of myocardial infarction (MI) and mortality remains unknown. OBJECTIVE To evaluate the effects of various combinations of the allergic triad on the risk of MI and mortality. METHODS Adult allergic disease patients without prior MI were enrolled from the nationwide health check-up data provided by the Korean National Health Insurance Service in 2009. The primary and secondary end points were all-cause death and MI. RESULTS A total of 9,548,939 individuals older than 20 years were selected for analysis. The prevalence of allergic diseases was 13.9% for AR, 0.4% for AD, and 2.7% for asthma. During a median 8.2 years of follow-up, 105,659 MIs and 298,769 deaths occurred. All allergic diseases were associated with an increased risk of MI (AR, adjusted hazard ratio [HRadjust], 1.11, 95% CI, 1.10-1.13; AD, HRadjust, 1.14, 95% CI, 1.06-1.24; asthma, HRadjust, 1.37, 95% CI, 1.33-1.40), whereas mortality risk was increased only for patients with AD (HRadjust, 1.15; 95% CI, 1.10-1.20) or asthma (HRadjust, 1.41; 95% CI, 1.39-1.43). Among the combinations of allergic diseases, patients with both AD and asthma had the highest risk of mortality (HRadjust, 1.71; 95% CI, 1.46-2.00) and MI (HRadjust, 1.57; 95% CI, 1.15-2.16). The results were significant after adjusting for demographic characteristics, comorbidities, socioeconomic status, and lifestyle factors. CONCLUSIONS Patients with both AD and asthma have the highest risk of MI and mortality among all allergic disease combinations. Physicians should evaluate combinations of allergic conditions in allergic disease patients and promptly assess and manage their future risk of MI and mortality.

Investigating causal relationships between Body Mass Index and risk of atopic dermatitis: a Mendelian randomization analysis. Sci Rep 2020; 10:15279. [PMID: 32943721 PMCID: PMC7498603 DOI: 10.1038/s41598-020-72301-2] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/08/2019] [Accepted: 08/24/2020] [Indexed: 01/07/2023] Open
Abstract
Population studies suggest that atopic dermatitis (AD) is associated with an increased risk of obesity, however a causal relationship between these two conditions remains to be established. We therefore use Mendelian randomization (MR) to evaluate whether obesity and AD are causally interlinked. We used summary statistics extracted from genome wide association studies of Body Mass Index (BMI) and AD. MR analysis was performed in both directions to establish the direction of causality between BMI and AD. We find that genetically determined increase in adiposity is associated with increased risk of AD (odds ratio of AD 1.08 [95% CI 1.01 to 1.14; p = 0.015] per unit increase in BMI). Conversely, genetically determined increased risk of AD is not associated with a higher BMI (change in BMI attributable to AD based on genetic information: 0.00; 95% CI − 0.02 to 0.02; p = 0.862). There was no evidence for confounding of these genetic analyses by horizontal pleiotropy. Our results indicate that the association of AD with obesity is likely to reflect a causal role for adiposity in the development of AD. Our findings enhance understanding of the etiology of AD, and the basis for experimental studies to evaluate the mechanistic pathways by which adiposity promotes AD.

Abstract
Atopic dermatitis (AD) is a common inflammatory skin disease, clinically characterized by recurrent eczematous lesions and intense itching, leading to excoriations and susceptibility to cutaneous infections. Although it is considered a pediatric disorder, mainly starting in infancy, it is also very common in adults. Etiology of AD is complex and multifactorial: interaction between genetic susceptibility and environment, but also cutaneous barrier impairment, change in microbiome composition and innate and adaptive immune dysregulation are the main factors involved in the pathogenesis of the disease. Originally, the disorder was considered mediated by an imbalance towards a T-helper 2 response and excessive IgE production to allergens, but now it is recognized as a lifelong disposition with variable clinical expressivity, where dysfunctions of the epidermal barrier, immune system and microbiome play a central role. AD leads to a substantial psycho-social burden on patients and their relatives and increases the risk of other allergic and non allergic disorders. The real economic impact of AD is difficult to measure due to the broad spectrum of disease severity and the multiple direct and indirect costs, but the overall medical expenses seem to be very high and similar to those of other diseases such as diabetes. Currently, a multiple therapeutic approach is aimed only at improving the skin state, reducing itching and keeping a stable condition. New safety and curative treatments may be developed only after enhancing our understanding on the pathogenesis of AD and the heterogeneity of its clinical manifestations. (www.actabiomedica.it)

Abstract
BACKGROUND Little is known about the impact of multimorbidity in childhood atopic dermatitis (AD). OBJECTIVE We sought to determine the likelihood and predictors of chronic disease multimorbidity in childhood AD. METHODS Data were examined for children (<18 years) in the 1996-2015 Medical Expenditure Panel Survey, an annual, representative sample of United States households. Multimorbidity was assessed using Charlson Comorbidity Index (CCI), Healthcare Utilization Project Chronic Comorbidity Indicator (HCUP-CCI) and frequency of atopic comorbidities. RESULTS Young children with mild-moderate and severe AD, and adolescents with mild-moderate AD had higher CCI scores. Similarly, young children and adolescents with mild-moderate and severe AD had increased HCUP-CCI scores. Children with AD and atopic disease had higher CCI and HCUP-CCI scores than children with either alone. Young children and adolescents with mild-moderate and severe AD had more atopic comorbidities. CONCLUSIONS Pediatric AD is associated with increased atopic and non-atopic multimorbidity. Comorbid atopic disease may identify a subset of children with AD who particularly benefit from enhanced screening and management of multimorbidity.

Mapping Dermatology Life Quality Index (DLQI) scores to EQ-5D utility scores using data of patients with atopic dermatitis from the National Health and Wellness Study. Qual Life Res 2020; 29:2529-2539. [PMID: 32297132 PMCID: PMC7434755 DOI: 10.1007/s11136-020-02499-1] [Citation(s) in RCA: 16] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 04/04/2020] [Indexed: 12/02/2022]
Abstract
PURPOSE To develop a mapping algorithm for generating EQ-5D-5-level (EQ-5D-5L) utility scores from the Dermatology Life Quality Index (DLQI) in patients with atopic dermatitis (AD). METHODS The algorithm was developed using data from 1232 patients from four countries participating in the National Health and Wellness Study. Spearman's rank correlation coefficient was used to evaluate the conceptual overlap between DLQI and EQ-5D-5L. Six mapping models (ordinary least squares [OLS], Tobit, three different two-part models, and a regression mixture model) were tested with different specifications to determine model performance and were ranked based on the sum of mean absolute error (MAE), and root mean squared error (RMSE). RESULTS The mean DLQI score was 7.23; mean EQ-5D-5L score was 0.78; and there were moderate negative correlations between DLQI and EQ-5D-5L scores (p = - 0.514). A regression mixture model with total DLQI, and age and sex as independent variables performed best for mapping DLQI to EQ-5D-5L (RMSE = 0.113; MAE = 0.079). CONCLUSION This was the first study to map DLQI to EQ-5D-5L exclusively in patients with AD. The regression mixture model with total DLQI, and age and sex as independent variables was the best performing model and accurately predicted EQ-5D-5L. The results of this mapping can be used to translate DLQI data from clinical studies to health state utility values in economic evaluations.

Abstract
Atopic diseases refer to common allergic inflammatory diseases such as atopic dermatitis (AD), allergic rhinitis (AR), and allergic asthma (AA). AD often develops in early childhood and may herald the onset of other allergic disorders such as food allergy (FA), AR, and AA. This progression of the disease is also known as the atopic march, and it goes hand in hand with a significantly impaired quality of life as well as a significant economic burden. Atopic diseases usually are considered as T helper type 2 (Th2) cell-mediated inflammatory diseases. Thymic stromal lymphopoietin (TSLP), an epithelium-derived pro-inflammatory cytokine, activates distinct immune and non-immune cells. It has been shown to be a master regulator of type 2 immune responses and atopic diseases. In experimental settings, the inhibition or knockout of TSLP signaling has shown great therapeutic potential. This, in conjunction with the increasing knowledge about the central role of TSLP in the pathogenesis of atopic diseases, has sparked an interest in TSLP as a druggable target. In this review, we will discuss the autocrine and paracrine effects of TSLP, how it regulates the tissue microenvironment and drives atopic diseases, which provide the rationale for the increasing interest in TSLP as a druggable target.

Abstract
Atopic dermatitis (AD) is a chronic inflammatory skin disease that is characterized by complex pathophysiology involving both skin barrier dysfunction and aberrant type 2 inflammation/immune responses. AD can be a debilitating condition that drastically impairs quality of life, especially in patients with moderate-to-severe disease. Currently, topical therapies such as corticosteroids and non-steroidal immunomodulatory therapy provide limited efficacy for patients with moderate-to-severe AD; limitations include inadequate response, cutaneous toxicity from overuse, and poor tolerance due to stinging and burning. Historically, the development of targeted therapies has been challenging due to the complex and multifaceted etiology of AD. Recent progress in understanding the immunopathology of AD reinforces the development of newly targeted therapeutics. The successful launch of dupilumab, a monoclonal antibody targeting the interleukin (IL)-4α receptor subunit, for AD in 2017 spurred the development of a number of biologics targeting novel cytokine and receptor targets that are now in phase II and III of development. This review aims to explore the rationale behind these novel biological therapies and to summarize current clinical studies of these agents.

Abstract
BACKGROUND Recent data suggest that patients with atopic dermatitis (AD) have increased systemic immune activation and cardiovascular risk. However, unlike psoriasis, evaluation of active vascular inflammation using state-of-the-art imaging is lacking in AD. OBJECTIVE To assess aortic and carotid vascular inflammation using 18F-fluorodeoxyglucose-positron emission tomography/magnetic resonance imaging (18F-FDG-PET/MRI) imaging in moderate-to-severe AD versus healthy individuals. METHODS A total of 27 patients with moderate-to-severe AD and 12 healthy controls were imaged using 18F-FDG-PET/MRI. Target-to-background ratio (TBR) values were calculated in multiple segments of the aorta and carotid vessels. RESULTS Patients with AD had elevated aortic max TBR (fold change [FCH] = 1.45, P = .057) versus healthy controls and significantly elevated mean TBR (FCH = 1.20; P < .05) in the right carotid (RC) arteries versus controls. When examining greatest focal inflammation (most diseased segment [MDS] TBR), patients with AD had higher aortic inflammation (FCH = 1.28; P = .052). AD clinical severity significantly correlated with C-reactive protein (ρ = 0.60, P < .01) and with RC mean TBR levels (ρ = 0.60, P = .04). Stratifying patients into moderate-to-severe and very severe AD showed greater RC mean TBR in patients with very severe AD versus controls (FCH = 1.31; P = .02) and versus patients with moderate/severe AD (FCH = 1.23, P = .05). Aortic inflammation was also significantly greater in patients with very severe AD versus controls (max TBR: FCH = 1.6, P = .04; MDS TBR: FCH = 1.73, P = .03). CONCLUSIONS This preliminary study is the first that establishes greater vascular (aorta and carotid) inflammation in moderate-to-severe AD versus healthy controls. Furthermore, very severe AD showed higher inflammation than both moderate/severe patients and healthy controls. Future studies with larger patient cohorts and evaluation before and after treatment are needed to determine the extent to which vascular inflammation in AD is modifiable.

Abstract
Background While the incidence of patients with atopic dermatitis (AD) with atopic march (AM) showing respiratory allergy is steadily rising, the pathomechanism is still unknown. There are currently no biomarkers to predict progression of AM. Methods To explore the mechanism of AM, patients with AD and AM and healthy controls were recruited and RNA microarray, flow cytometry, quantitative real-time polymerase chain reaction, and immunofluorescence staining were performed. We also co-cultured dendritic cells and CD4+T cells with various Dermatophagoides farinae allergen fractions. Cytokine levels were evaluated using enzyme-linked immunosorbent assay. Findings Both fatty-acid-binding protein 5 (FABP5) and Th17-related genes were more highly expressed in AM. FABP5 knockdown significantly decreased Th17-inducing cytokines in keratinocytes and IL-17A in T cells from AM patients. Further confirmation was obtained using an AM mice model compared to mice without AM. Der f 1, a major D. farinae allergen, increased FABP5 and IL-17A expression in T cells from AM patients. Higher serum FABP5 levels from AM patients were positively correlated with serum IL-17A levels. Interpretation FABP5 expression, possibly enhanced by higher epicutaneous and respiratory sensitization to Der f 1, may directly promote Th17 responses in AD patients with AM. Thus, AM progression can be explained by Th17 reaction induced by FABP5. FABP5 was identified as a potential biomarker in AM. Funding This study was supported by the National Research Foundation of Korea (NRF) grant funded by the Korea government (Ministry of Science and ICT; No. NRF-2017R1A2B4009568), grants of the Korean Health Technology R&D Project, Ministry for Health, Welfare & Family Affairs, and the Republic of Korea (HI13C0010, HI14C1324, HI14C1799).

Abstract
Atopic dermatitis is associated with an increased risk of asthma (10 to 30% according to age), allergic rhinitis and conjunctivitis and food allergy. Other comorbidiies are globally lest frequent than in psoriasis. There is no increased risk of solid cancer. Smoking is a major confounding factor that has to be taken into account. Obesity and metabolic syndrome are more frequent and there is a moderately increased cardiovascular risk in severe forms of atopic dermatitis. There is a clear-cut increased risk of vitiligo and alopecia areata and a lower risk of other auto-immune diseases, including type I diabetes in children. There is a higher risk of cutaneous but not extra-cutaneous bacterial and viral infections, and increased frequency of contact dermatitis and urticaria. Severe atopic dermatitis is associated with psychiatric comorbidities, like attention disorders/hyperactivity, depression and suicidal ideas. © 2019 Elsevier Masson SAS. All rights reserved.

Abstract
BACKGROUND Atopic dermatitis has been linked to increased risk of many comorbidities. However, the risks of certain comorbidities are still debated. OBJECTIVE To better characterize the basic demographics, treatment patterns, and associations between atopic dermatitis and comorbidities and to further investigate the influence of severity on comorbidities. METHODS We used a sample cohort of 999,992 people from the National Health Insurance Research Database of Taiwan to evaluate atopic dermatitis in the general population. RESULTS A total of 12,780 patients with atopic dermatitis in 2010 were identified. The prevalence was 1.28%. The proportions of severe and moderate cases were 7.43% and 19.26%, respectively. The most commonly used systemic treatment was corticosteroids. Compared with the general population, atopic dermatitis patients showed increased risks of all 9 groups of comorbidities, including autoimmune disorders, atopic disorders, chronic urticaria, ocular disorders, metabolic disorders, hypertensive disorders, ischemic heart disorders, cerebrovascular disorders, and psychiatric disorders. The severity and persistence of atopic dermatitis were correlated with the development of certain comorbidities. LIMITATIONS Miscoding and misclassification might have occurred, and only patients with active disease were enrolled. CONCLUSION Patients with atopic dermatitis have higher risks of various comorbidities. Comprehensive monitoring and treatment plans are needed to better manage these patients.
