Emergency nurse practitioners are expected to assess and manage a variety of patients. These patients may present with urgent care-type complaints to severe life-threatening illnesses or injuries. For some, dermatological problems can sometimes be just as challenging as a critically ill patient. Atopic dermatitis (AD) is one, if not, the most common chronic inflammatory disease. Its presentation can vary depending on the age of the patient, the patient's skin tone, and other comorbidities. Patients often seek emergency care related to the condition itself or associated complications. This article includes a review of the pathophysiology, clinical manifestations, and standard management of AD. Finally, the potential complications of AD are discussed. A better understanding of AD will allow emergency nurse practitioners to properly identify and treat this chronic condition, as well as its complications. [ABSTRACT FROM AUTHOR]

Introduction: Keloids are a fibroproliferative, multifactorial, cutaneous disorder whose pathophysiology is not completely understood. Various factors such as high blood pressure, pregnancy, female gender, mechanical tension of local sites, and prolonged wound healing are known to worsen keloids. Childhood-onset keloids are keloids that form before 10 years of age, before various factors in adulthood come into play, and thus studying childhood-onset keloids may provide additional insight into the underlying mechanisms that lead to keloid formation. Methods: Retrospective chart review was performed on all patients with childhood-onset keloids who were evaluated at our plastic surgery clinic (one of the largest keloid referral centers in Japan) over a 1-year period. Results: Of the 1443 patients with diagnosis of keloids, 131 patients had childhood-onset keloids. Of these, 106 patients (80.9%) were female, 38.9% of patients had family history of keloids, and 48.9% of patients had allergies or allergy-related conditions (asthma, atopic dermatitis, or allergic rhinitis). Vaccination (47.5%) and chickenpox (19.9%) were the most common triggers. Of vaccinations, BCG was the most common trigger. The majority of keloids from BCG were in female patients (92.9%). The most common location was the chest in male patients (30.0%) and the arm in female patients (41.1%). Conclusion: To our knowledge, this is the largest report in the literature on childhood-onset keloids. There was overall female predominance in childhood-onset keloids, and even more significant female predominance in BCG-induced keloids. [ABSTRACT FROM AUTHOR]

Background Atopic eczema (AE) is a chronic relapsing, pruritic disease that greatly affects the child and family's quality of life (QoL). It is usually common and severe among children of Bangladeshi ethnicity. Objectives This is a cross-sectional quantitative study in patients with AE of Bangladeshi origin, which aims to analyse different components of the family, children and adult quality-of-life indices and their relationship to patient age, sex, eczema severity and distribution, other allergic associations, parental education and socioeconomic level. Methods Children and young adults of Bangladeshi origin aged 0–30 years, clinically diagnosed with AE were recruited as part of the Tower Hamlets Eczema Assessment project, a clinical phenotyping study of AE in the Bangladeshi population living in East London. Questionnaires completed by children/parents included the Family Dermatology Life Quality Index (FDLQI), Infant's Dermatology Quality of Life (IDQOL) and the Children's Dermatology Life Quality Index (CDLQI). Young adults completed the Dermatology Life Quality Index (DLQI). The disease severity was assessed objectively using the Eczema Area Severity Index (EASI). Patients and parents who did not read or speak English were aided by Bengali/Sylheti-speaking research assistants. Results Overall, 460 Bangladeshi children and 98 adults with AE were recruited. Burden of care, extra housework and emotional distress were the highest affected domains in parental QoL, while itching and sleep were the highest for children. Significant factors influencing FDLQI score were EASI [marginal effect (ME) 1.01, 95% confidence interval (CI) 1.00–1.03; P = 0.004], age (ME 0.98, 95% CI 0.97–0.99; P = 0.004), extensor eczema distribution (ME 1.25, 95% CI 1.03–1.52; P = 0.023), parental English fluency (ME 1.29, 95% CI 1.10–1.52; P = 0.002) and atopic comorbidities (ME 1.10, 95% CI 1.04–1.17; P = 0.001). Parental socioeconomic class was a nonsignificant factor. IDQOL/CDLQI was influenced significantly by the child's age (ME 0.99, 95% CI 0.97–1.00, P = 0.023), 'nonclear' eczema distribution clusters especially the 'severe extensive' cluster (ME 1.46, 95% CI 1.15–1.84; P = 0.002) and nonsignificantly by EASI and parental English literacy and socioeconomic levels. DLQI was affected significantly by nonclear eczema distribution groups especially 'severe extensive' (ME 2.49, 95% 1.76–3.53; P < 0.001) and nonsignificantly by patient age, and female sex. Conclusions AE is a chronic disease where many external factors other than disease severity affect QoL of patients and their families, -especially in under-represented minority groups who face different linguistic and cultural barriers.

Introduction: In pivotal phase 3 tralokinumab monotherapy (ECZTRA 1/2) and topical corticosteroid (TCS) combination (ECZTRA 3) trials in adults with moderate-to-severe atopic dermatitis (AD), tralokinumab significantly improved signs and symptoms of AD. Geographic region may impact treatment response due to potential differences in race and ethnicity, and based on findings in other therapy areas. Here, we evaluated the efficacy and safety of tralokinumab in the ECZTRA 1/2/3 North American population at week 16, as well as maintenance of responses over time, and compared these data side-by-side with those of the ECZTRA 1/2/3 non-North American population. Methods: Primary endpoints were Investigator's Global Assessment score of 0 or 1 (IGA 0/1; clear or almost clear) or at least 75% improvement in Eczema Area and Severity Index (EASI-75) at week 16. At week 16, tralokinumab-treated IGA 0/1 or EASI-75 responders were re-randomized 2:2:1 to tralokinumab 300 mg q2w, or q4w, or placebo (ECZTRA 1/2) and 1:1 to tralokinumab 300 mg q2w or q4w (ECZTRA 3). Results: Overall, 559/1596 (35%) and 160/380 (42.1%) patients randomized in ECZTRA 1/2 and ECZTRA 3 were from North America, respectively. At week 16, IGA 0/1 and EASI-75 response rates were greater with tralokinumab versus placebo in ECZTRA 1/2 (IGA 0/1: 25.3% vs 15.1%; 95% confidence interval [CI] 3.0, 17.3; p = 0.012; EASI-75, 40.1% vs 19.4%; 95% CI 12.6, 28.7; p < 0.001) and ECZTRA 3 (IGA 0/1, 40.0% vs 25.9%; 95% CI − 0.5, 28.3; p = 0.074; EASI-75: 58.1% vs 37.0%; 95% CI 4.9, 37.0; p = 0.012) and tralokinumab was well tolerated in the North American population. Patients with IGA 0/1 or EASI-75 response at week 16 demonstrated sustained responses at week 52 and week 32 in ECZTRA 1/2 and ECZTRA 3, respectively. Similar findings were observed in the non-North American trial populations. Conclusions: Tralokinumab, with or without TCS, displayed similar efficacy and safety in patients with moderate-to-severe AD across the North American population, and was comparable to the non-North American population. Clinical Trial Registration: NCT03131648 (registered 27-Apr-2017); NCT03160885 (registered 19-May-2017); NCT03363854 (registered 6-Dec-2017). [ABSTRACT FROM AUTHOR]

This study was aimed to find the most prevalent microbial isolates, as well as measurement of total serum IgE, LPS levels and their correlation with Atopic dermatitis occurrences. A 88 patients were collected randomly (47 females and 41 males), through a period Sep. 2019 to Feb. 2020 from Al Zafaraniyah General Hospital. Patients ages ranged between 10 months to 30 years. In addition, the control samples are collected randomly from 20 apparently healthy people. Microbial isolation results showed that the most prevalence microbial isolates in atopic skin patients were; Staphylococcus spp. 81 (30.10%), fungi 65 (24.20%), Bacillus spp. 53 (19.70%), Enterobacteriaceae spp. 32 (11.90%), Acinetobacter spp. 16 (5.90%), Corynobacterium spp. 10 (3.70%), Streptococcus spp. 8(3.00%) and Pseudomonas spp. 4 (1.50%) compared with control group. Antimicrobial susceptibility test was carried out for nine antimicrobial agents. The results showed that, most bacterial isolates are become a multidrug resistant especially Staphylococcus spp. and Enterobacteriaceae spp. whilst two other tests in a concern with the AD patients which are IgE and LPS, both parameters results show that, the age from 0 - 2 years, is recorded higher serum level than other age categories.

Introduction: The Biologics in Atopic Dermatitis: Experiences & Learnings (BADEL) project aims to improve real-life understanding of how, where, and when biologics can play a role in the treatment of atopic dermatitis (AD) from the perspective of healthcare professionals (HCPs) and patients. Methods: Individual experiences of 24 patients with moderate-to-severe AD and who had been treated with biologic therapy (dupilumab) for ≥ 3–6 months, and 20 HCPs with a sub-specialty interest in AD were collected by means of focus groups held in Canada, Germany, France, Italy and the United Kingdom. Dupilumab was the only biologic therapy available at the time of the study. Results: Most patients had suffered from AD for many years, particularly from itch and psychosocial issues, with AD negatively impacting all aspects of their life. They had experienced a long treatment journey and seen many dermatologists, enduring treatment delays and failures. They had been prescribed various therapies without long-term success. Biologics provided symptom improvement, offering many patients a near-normal quality of life. Side effects, especially conjunctivitis, were the greatest drawback, and there were a few issues with incomplete or unreliable efficacy. HCPs agreed that biologic therapy for AD in the majority of patients demonstrated rapid onset, good efficacy and tolerability, and are a viable option in patients who had exhausted all other treatment options. However, those patients who failed to sufficiently respond or developed intolerable adverse effects, particularly ocular symptoms, require alternative therapeutic options. Conclusion: Biologics can provide a near-normal quality of life for many patients with AD. Patients with AD who have failed conventional therapies should be offered all such novel therapies. Education and good patient–HCP communication will enable patients to manage their disease and treatment expectations. Patients and HCPs alike eagerly await alternative targeted therapies, which will offer greater choice and flexibility. [ABSTRACT FROM AUTHOR]

Objective. To investigate the correlation between serum immune factor levels and allergic constitution in children with infectious mononucleosis. Methods. A total of 120 children who visited our hospital from March, 2019, to December, 2020, were selected as the research objects, and 40 children who came to our hospital for physical examination were included in the control group (CG). 40 children with IM were classified into the IM group (IG), and 40 IM children with allergic rhinitis, allergic dermatitis, asthma, and other allergic diseases were classified into the IM allergy group (AG). On the second day of admission, 5 ml of fasting venous blood was collected from all children in the early morning to observe the serum IgE level, the level of lymphocyte subsets, and the level of immunoglobulin of the patient. Results. The serum CD3, CD4, and CD8 levels of children in AG were significantly higher than those in IG and CG (P < 0.05). The serum IgE, IgA, IgM, and IgG levels of children in AG were significantly higher than those of IG and CG (P < 0.05). The serum IgE levels of children in AG were positively correlated with the serum CD3, CD4, and CD8 levels (P < 0.05). There was a positive correlation between the serum IgE level and serum IgA, IgM, and IgG levels in children with AG (P < 0.05). Conclusion. The results of this study showed that there may be a certain relationship between allergic constitution and the incidence, clinical manifestations, and prognosis of infectious mononucleosis. IgE level can be used as a reference index for the early severity of IM clinical symptoms. [ABSTRACT FROM AUTHOR]

Introduction: In phase III trials in adolescents and children with atopic dermatitis (AD), dupilumab significantly decreased global disease severity. However, the effects of dupilumab on the extent and signs of AD across different anatomical regions were not reported. Here we characterize the efficacy of dupilumab in improving the extent and signs of AD across four different anatomical regions in children and adolescents. Methods: A post hoc subset analysis was performed using data from two randomized, double-blind, placebo-controlled, international multicenter, phase III trials of dupilumab therapy in adolescents aged ≥ 12 to < 18 years with moderate-to-severe AD and children aged ≥ 6 to < 12 years with severe AD. Endpoints included mean percentage change in Eczema Area and Severity Index (EASI) signs (erythema, edema/papulation, excoriation, lichenification) and extent of AD (measured by percentage of body surface area [% BSA] involvement) from baseline to week 16 across four anatomical regions (head and neck, trunk, upper extremities, lower extremities). Results: Dupilumab improved both the extent and severity of AD signs across the four anatomical regions. Improvements were shown to be similar across the four anatomical regions for % BSA involvement and for reduction in EASI signs. Improvements in all signs were seen early, within the first 4 weeks of treatment, and were sustained through week 16, across all regions. Conclusions: In pediatric patients 6 years of age and older, treatment with dupilumab resulted in rapid and consistent improvement in the extent and signs of AD across all anatomical regions. ClinicalTrials.gov Identifiers: LIBERTY AD ADOL (NCT03054428) and LIBERTY AD PEDS (NCT03345914).

Background: The World Health Organization (WHO) identified allergy as one of the major problems of the 21st century. It was also stated to be a key issue for health protection and public health care activity in the White Book on Allergy published in 2011. An allergy or atopy is called type I hypersensitivity. It may take the form of immediate (anaphylaxis) or late symptoms including allergic rhinitis and eye diseases, atopic dermatitis, food allergies, anaphylactic shock, allergic asthma and hives. Anaphylaxis and anaphylactic shock can occur at any age. Aim of the study: The goal of the study was to assess patient knowledge about allergies and appropriate actions to take in situations of severe allergic symptoms including anaphylactic shock. Material and methods: The study was conducted in 2018 among 150 adult patients in a clinic of Allergy at Optima Medycyna SA in Opole. The author's survey questionnaire contained 27 closed single or multiple-choice questions. Results: A satisfactory level of knowledge of the most life-threatening allergy exacerbations was found in 79.3% (119) of the examinees. 53.3% (80) had correct knowledge of how to act in the case of a severe allergic shortness of breath and symptoms that do not subside despite administering medications. In such instances, 46.7% did not know what to do. Only 84.7% (127) of respondents knew the definition of anaphylactic shock while 10% (15) did not know the concept at all. Conclusions: Patients showed a significantly higher level of knowledge about allergy complications than about their causes and prevention. Knowledge about the diagnosis of allergy exacerbations, as well as steps to take in life-threatening situations associated with acute allergic disease and anaphylactic shock in home situations was insufficient. In addition, it was found that nursing staff insufficiently educate patients on allergies and associated complications. [ABSTRACT FROM AUTHOR]

Background: Clothing fabrics interact closely with the skin to shape our cutaneous microenvironment. Cotton and silk have been traditionally recommended for patients with atopic dermatitis because of reported patient comfort. New synthetic fabrics combine anti-microbial, anti-inflammatory, moisture-wicking, and soothing properties that may augment conventional management strategies in atopic patients. Objective: We review existing and emerging evidence for fabric selection in patients with atopic dermatitis including cotton, wool, lyocell, silk, anionic, cellulosic/cellulose based, zinc oxide coated, citric acid coated, chitosan coated, silver coated, borage seed oil coated, ethylene vinyl, and polyurethane and offer practical suggestions for clothing and bedding choices. Methods: A systematic search was conducted on PubMed and EMBASE electronic databases for articles from 1 January, 1994 to 1 January, 2020. Studies were included based on the following inclusion criteria: clinical trial, published in English, and fabric as the main agent being evaluated. Case reports, case series, conference abstracts, reviews, animal studies, and duplicates were excluded. Studies were then manually screened by title, abstract, and full-text articles and selected to specifically describe the effects of fabrics in patients with atopic dermatitis. Both adult and pediatric patient studies were included. Results: There appears to be an advantage to modern fabric manufacturing and processing techniques that have created smaller diameter, smoother fibers such as super- and ultrafine merino wool and anti-microbial finishes. Traditional cotton and silk fabrics have mixed evidence in improving atopic dermatitis symptoms and severity but have shown to be generally safe. Large-diameter wool has been shown to induce itching and irritation; ultra- or superfine merino wool is non-pruritic and may be recommended as an alternative. Emerging fabrics with potential efficacy in reducing atopic dermatitis severity and Staphylococcus aureus burden include silver-coated, chitosan-coated, and cellulose-based fabrics. Zinc oxide-coated, acid-coated, polyurethane-coated, borage seed oil-coated, anionic, lyocell, and ethylene vinyl fabrics have sparse evidence and require further study before conclusions can be made. Conclusions: Appropriate fabric selection can reduce the symptom severity and exacerbations of atopic dermatitis. [ABSTRACT FROM AUTHOR]

Objective: To investigate the clinical features and follow-up results of the patients with transient hypogammaglobulinemia of infancy (THI) and to understand to what extent the condition coexists with allergic diseases. Materials and Methods: Between January 2010 and February 2019, 172 patients who had been referred to Ankara University Faculty of Medicine's Pediatric Immunology and Allergy Outpatient Department for findings of atopic disease or for frequent infections with a suspicion of PID, who were diagnosed with THI, and followed-up for at least one year were included in this study. Their clinical and immunological features and follow-up results were evaluated retrospectively. Results: Of the 172 patients, 59% were boys. Median time of symptom onset was 14 months (1-46 months), median time of admission was 20 months (6-30 months), and consanguineous marriages were seen in 20% of the families. The most common referral complaints were respiratory tract infections and non-wheezing allergic diseases with rates of 71.5% and 27%, respectively. Cellular immune system analyses were normal. During a median follow-up time of 36 months, 42% of the patients recovered, 25% (n=43) still had THI, 25% (n=43) had unclassified hypogammaglobulinemia (UCG), 4% (n=7) had partial IgA deficiency, and 4% (n=7) had partial IgM deficiency. Allergic diseases were seen in 46% of the patients. An asthma diagnosis was made in 35.4% of the patients, allergic rhinitis in 5% and atopic dermatitis in 12.7%. The skin prick test was positive in 15% of them. Conclusion: THI mostly improves spontaneously in time. However, hypogammaglobulinemia can last until later years in life in a group of patients. Allergic diseases increase with the presence of THI. In patients who are admitted with allergic disease symptoms, underlying hypogammaglobulinemia should also be investigated. [ABSTRACT FROM AUTHOR]

Although artificial intelligence has been available for some time, it has garnered significant interest recently and has been popularized by major companies with its applications in image identification, speech recognition and problem solving. Artificial intelligence is now being increasingly studied for its potential uses in medicine. A sound understanding of the concepts of this emerging field is essential for the dermatologist as dermatology has abundant medical data and images that can be used to train artificial intelligence for patient care. There are already a number of artificial intelligence studies focusing on skin disorders such as skin cancer, psoriasis, atopic dermatitis and onychomycosis. This article aims to present a basic introduction to the concepts of artificial intelligence as well as present an overview of the current research into artificial intelligence in dermatology, examining both its current applications and its future potential.

At the time of this study, prior to the introduction of biologics in the US, systemic therapies used for the treatment of moderate-to-severe atopic dermatitis included off-label immunosuppressants and corticosteroids. Immunosuppressant therapy is associated with a substantial risk of side-effects, therefore needing clinical monitoring, and is likely to incur a significant healthcare burden for patients and payers. This retrospective cohort study based on claims data measured immunosuppressant use and its associated burden among US adult patients with atopic dermatitis covered under commercial or Medicare Supplemental insurance from January 01, 2010, to September 30, 2015. Overall, based on age, gender, region, and index year, 4201 control patients with atopic dermatitis without immunosuppressant use were matched with 4204 patients treated with immunosuppressants. The majority (68.5%) of patients using immunosuppressants were non-persistent with immunosuppressant treatment during the 12-month follow-up period after a mean (standard deviation) of 88.1 (70.7) days of immunosuppressant use; 72.3% required systemic steroid rescue treatment. Immunosuppressant users had higher incidence of immunosuppressant-related clinical events than controls; in addition, a larger proportion of immunosuppressant users versus controls developed cancer (0.28% vs 0.14%, respectively; P < 0.0001). Healthcare utilization and costs associated with clinical events and monitoring were also higher for immunosuppressant users compared with controls (total costs, $9516 vs $1630, respectively; P < 0.0001; monitoring costs, $363 vs $54, respectively; P < 0.0001). This study revealed that patients treated with systemic immunosuppressants often require systemic steroids or changes to treatment. The increase in immunosuppressant-related clinical events, including the need for increased monitoring with immunosuppressant treatment, compared with controls demonstrates a substantial treatment burden and highlights the unmet need for more effective long-term therapies for atopic dermatitis with improved safety profiles and reduced monitoring requirements.

Objective: Numerous studies have reported that various environmental factors during early life are key determinants for developing allergic disease. Herein, we aimed to investigate the impact of environmental factors on allergic rhinitis.Methods: This cross-sectional study was conducted in a single university in Japan (from April to June, in 2015 and 2016). Students voluntarily answered online questionnaires regarding their allergic rhinitis symptoms and their exposure to various environmental factors during preschool-age.Results: Overall, 3075 students participated the questionnaire. After excluding those with incomplete datasets, 3016 students were eligible. Of these, 49% had allergic rhinitis symptoms. Female sex was associated with a lower risk of allergic rhinitis symptoms (odds ratio [OR], 0.82; 95% confidence interval [CI], 0.68-0.99). Comorbidity of asthma or atopic dermatitis and a family history of allergy (asthma, atopic dermatitis, or allergic rhinitis) were associated with higher risks of allergic rhinitis symptoms. Regarding the number of household members, compared with subjects with <3 people, those with 5 (OR, 0.74; 95% CI, 0.57-0.97) and ≥6 people (OR, 0.66; 95% CI, 0.49-0.88) in their household showed lower incidences of allergic rhinitis symptoms. No other environmental factors, including birth order, number of siblings, living environment, passive smoking, furry pet ownership, housing, bedding, breastfeeding, dairy product intake, preschool setting, and starting age of preschool, was associated with the incidence of allergic rhinitis symptoms.Conclusion: Sex, current asthma and atopic dermatitis symptoms, family history of allergies, and the number of people in the household at preschool-age were associated with the incidence of allergic rhinitis symptoms.

Abstract: Vitiligo is a common skin disorder characterized by idiopathic, progressive cutaneous hypomelanosis. Vitiligo is associated with several comorbid autoimmune, systemic, and dermatological diseases, primarily thyroid disease, alopecia areata, diabetes mellitus, pernicious anemia, systemic lupus erythematosus, rheumatoid arthritis, Addison's disease, inflammatory bowel disease, Sjögren's syndrome, dermatomyositis, scleroderma, ocular and audiological abnormalities, psoriasis, and atopic dermatitis. It is essential to increase awareness of these comorbidities in order to improve the disease burden and quality of life of patients with vitiligo. Herein, we review the association with the most frequent comorbidities associated with vitiligo. [ABSTRACT FROM AUTHOR]

Atopic dermatitis (AD) is a chronic inflammatory skin disease where more than 90% of patients affected are colonized with Staphylococcus aureus. In AD, S. aureus δ-toxin is a major virulence factor causing cutaneous inflammation via mast cell degranulation. δ-toxin is controlled by the S. aureus agr quorum sensing system, and thus we addressed whether interference with agr signaling would limit skin inflammation. Indeed, treatment of S. aureus with the agr-inhibitor solonamide B (SolB) abolished δ-toxin production and reduced skin inflammation in a mouse model of inflammatory skin disease, demonstrating the potential of antivirulence therapy in treating S. aureus-induced skin disorders.

Summary: The aim of this study is the evaluation of the relation between the sensitisation to outdoor and indoor fungi and allergy to peanuts and walnuts in atopic dermatitis patients aged 14 years and older. The complete dermatological and allergological examinations were performed in all included patients; the occurrence of food allergy to peanuts and walnuts was recorded (specific IgE, skin prick test, history of allergic reaction) and the sensitisation to mixture of outdoor fungi and indoor fungi was also examined (skin prick test, specific IgE). The statistical evaluation of the relation between the sensitisation to outdoor and indoor fungi and the occurrence of food allergy to peanuts and walnuts was performed; 329 patients were included in the study, 110 men and 219 women, the average age 26.8 years. The sensitisation to outdoor fungi was recorded in 91 patients (28%), the sensitisation to indoor fungi was recorded in 61 patients (18.5%), the occurrence of food allergy to peanuts was confirmed in 90 (27%) patients and to walnuts in 121 (36.7%) patients. We confirmed, that patients suffering from sensitisation to outdoor fungi suffer significantly more from food allergy to peanuts and walnuts. The significant relation between the sensitisation to indoor fungi and food allergy to peanuts and walnuts was not confirmed. [ABSTRACT FROM AUTHOR]

Abstract: Background: Barrier dysfunction is an important feature of atopic dermatitis (AD) in which IL‐4 and IL‐13, signature type 2 cytokines, are involved. Periostin, a matricellular protein induced by IL‐4 or IL‐13, plays a crucial role in the onset of allergic skin inflammation, including barrier dysfunction. However, it remains elusive how periostin causes barrier dysfunction downstream of the IL‐13 signal. Methods: We systematically identified periostin‐dependent expression profile using DNA microarrays. We then investigated whether IL‐24 downregulates filaggrin expression downstream of the IL‐13 signals and whether IL‐13‐induced IL‐24 expression and IL‐24‐induced downregulation of filaggrin expression are dependent on the JAK/STAT pathway. To build on the significance of in vitro findings, we investigated expression of IL‐24 and activation of STAT3 in mite‐treated mice and in AD patients. Results: We identified IL‐24 as an IL‐13‐induced molecule in a periostin‐dependent manner. Keratinocytes are the main IL‐24‐producing tissue‐resident cells stimulated by IL‐13 in a periostin‐dependent manner via STAT6. IL‐24 significantly downregulated filaggrin expression via STAT3, contributing to barrier dysfunction downstream of the IL‐13/periostin pathway. Wild‐type mite‐treated mice showed significantly enhanced expression of IL‐24 and activation of STAT3 in the epidermis, which disappeared in both STAT6‐deficient and periostin‐deficient mice, suggesting that these events are downstream of both STAT6 and periostin. Moreover, IL‐24 expression was enhanced in the epidermis of skin tissues taken from AD patients. Conclusions: The IL‐13/periostin pathway induces IL‐24 production in keratinocytes, playing an important role in barrier dysfunction in AD. [ABSTRACT FROM AUTHOR]

Summary: Background: Various allergenic proteins are produced by house dust mites (HDM). However, the allergenicity and clinical implications of these allergens are unknown. Objective: The purpose of this study was to identify allergens in Dermatophagoides farinae and elucidate the sensitization profiles to these in Korean patients suffering from respiratory (allergic rhinitis and/or asthma) and atopic dermatitis symptoms. Methods: IgE reactivities in sera from 160 HDM allergy patients were analysed by one‐ and two‐dimensional gel electrophoresis and immunoblotting. IgE‐reactive components were identified by liquid chromatography‐coupled electrospray ionization‐tandem mass spectrometry. Nine recombinant mite allergens (Der f 1, Der f 2, Der f 10, Der f 11, Der f 13, Der f 14, Der f 30, Der f 32 and Der f Alt a 10) were produced, and the IgE reactivity in sera to each was determined by ELISAs. Results: Der f 1 and Der f 2 were recognized by IgE in serum samples from 88.1% and 78.1% of all patients, respectively. Patients with respiratory allergies were mainly sensitized to these major allergens, whereas patients with atopic dermatitis symptoms showed polysensitization to major and minor allergen components (including Der f 11, Der f 13, Der f 14, Der f 32 and Der f Alt a 10). Conclusions: Patients with respiratory allergic disease sensitize to major allergen components of HDM. Those with atopic dermatitis were sensitized to a broader range of minor allergen components of HDM (Der f 11, Der f 13, Der f 14, Der f 32 and Der f Alt a 10). [ABSTRACT FROM AUTHOR]

Abstract: Background/Objectives: Atopic dermatitis is a common, chronic, debilitating disease. Poor adherence to treatment is the most important preventable contributor to adverse outcomes. Thus, improving adherence can improve patient outcomes. Text message reminders with embedded condition‐specific information have been shown to improve pediatric immunization adherence but have not been assessed in atopic dermatitis. The objective was to assess the effect of daily text messages on Eczema Area Severity Index scores and caregiver knowledge of atopic dermatitis. Methods: In this pilot randomized controlled trial, caregivers of children with atopic dermatitis enrolled during their initial appointment with a pediatric dermatologist and randomized 1:1 to standard care or daily text messages with patient education material and treatment reminders. Participants completed a multiple‐choice atopic dermatitis knowledge quiz at initial and follow‐up visits, and Eczema Area Severity Index scores were assessed. Results: Forty‐two patients enrolled, and 30 completed the study: 16 standard care group, 14 text message group. There was no significant difference in Eczema Area Severity Index score between the standard care and text message groups at follow‐up, with mean decreases in Eczema Area Severity Index score of 53% and 58%, respectively. Mean score on follow‐up atopic dermatitis knowledge quiz was significantly higher in the text message group (84% correct) than in the standard care group (75% correct) (P = .04). Conclusion: This pilot study did not demonstrate a difference in Eczema Area Severity Index scores with text message reminders. The significantly higher follow‐up atopic dermatitis quiz score in the text message group indicates that participants read and retained information from text messages. Limitations include small sample size and short duration of follow‐up. [ABSTRACT FROM AUTHOR]

Abstract: Background: Emollients are considered as a first‐line therapy for the treatment of atopic dermatitis (AD). However, evidence‐based proof that the regular use of emollients reduces AD severity is lacking. Objective: To assess whether the regular use of emollients results in a reduction in AD severity in children with AD. Methods: In this multicentre randomized, parallel group, open‐label study, children with mild‐to‐moderate AD were recruited during a flare. After flare resolution with a topical corticosteroid, patients were randomized to V0034CR emollient, reference emollient or no emollient (1:1:1 ratio), for 12 weeks. AD severity was assessed regularly by physicians [Scoring for Atopic Dermatitis (SCORAD) and subcomponents, IGA] and by parents (PO‐SCORAD and POEM). Results: A total of 335 patients were randomized to V0034CR (n = 111), reference emollient (n = 116) or no emollient (n = 108). After 12 weeks of treatment, SCORAD score was reduced by 5.28 points in the V0034CR group and by 3.36 points in the reference emollient group compared with the no emollient group (+4 points; P < 0.001 in both emollient groups vs. no emollient group). In a similar manner, PO‐SCORAD score was reduced by 4.88 and 2.67 points in the V0034CR and reference emollient groups, respectively, but increased by 2.90 points in the no emollient group (P < 0.001). Similar results were observed for POEM. A continuous decrease in all scores was observed over the 12‐week treatment period. At the end of the study, the percentage of patients in complete remission (i.e. without a new flare over the treatment period) was higher in the V0034CR (59.5%) and reference emollient (44.3%) groups than in the no emollient group (29.8%; P < 0.001). Conclusion: These results demonstrate that the regular use of emollients in children with mild‐to‐moderate AD reduces the severity of symptoms and, therefore, support their use as a first‐line treatment for these patients.

This study, carried out by a group from the Netherlands and Switzerland, explored the relationship between production of the antibody type known as IgG against components of the bacteria Staphylococcus aureus by patients with atopic eczema. This bacterium is frequently found on the skin of children and adults with atopic eczema and has been associated with worsening of the condition, largely through stimulation of the immune system or by causing an allergic response to the bacteria themselves. In this investigation the investigators looked for the presence of antibodies of the IgG class against different components of the bacteria in patients with atopic eczema and then compared this with the severity of the disease. They found that antibodies against products of the bacteria, sometimes known as virulence factors, that are involved in reducing normal immune responses are associated with increasing severity of the disease. An example of a bacterial product that reduces immunity in this study is a protein that causes destruction of human white blood cells. This suggests that these immunity-reducing components may also be factors that aggravate eczema by allowing the organisms to survive longer on the skin surface and it provides another explanation as to why the bacteria, Staphylococcus aureus, on eczematous skin should be reduced in number or removed completely.

Background: Azathioprine is frequently used in severe eczema. It is converted in the liver into active metabolites, including 6-thioguanine nucleotide (6-TGN) and methylated 6-methylmercaptopurine (6-MMP). In the past, the therapeutic potential of azathioprine may have not been fully utilized. Recent investigations on inflammatory bowel disease have led to a better understanding of azathioprine metabolism and optimizing treatment. Objective: To investigate whether measuring thiopurine metabolites in circulation can improve the effectiveness and safety of azathioprine treatment in patients with atopic dermatitis and/or chronic hand/foot eczema. Methods: Azathioprine metabolite levels were measured in eczema patients during maintenance treatment (Part I) and dose escalation (Part II). Clinical effectiveness, hepatotoxicity, and bone marrow suppression were analyzed and TPMT genotype was assessed. Results: A wide variation in metabolite levels in all dose groups was observed. In Part I (32 patients), there were no significant differences in 6-TGN levels between clinical responders and non-responders (p = .806). No hepatoxicity or myelotoxicity was observed. In Part II, all 6-TGN and 6-MMP levels increased during dose escalation. Hypermethylation was observed in 2/8 patients. Conclusion: For individual eczema patients treated with azathioprine, routinely measuring 6-TGN and 6-MMP can be helpful in optimizing azathioprine dose, improving clinical effectiveness, and preventing side effects.

Purpose: This is a review of emerging targeted, systemic therapies for atopic dermatitis (AD). The information presented aims to provide dermatologists with updated therapeutic options, stimulate academic interest, and spark future research. Material and methods: Extensive search of ClinicalTrials.gov, the National Eczema Association, and PubMed was performed for clinical trials examining the effect of emerging targeted, systemic therapies in patients with AD. Results were included if they demonstrated efficacy in reversing AD symptoms. Studies that did not demonstrate clinical benefit were excluded. Results: A number of emerging systemic agents targeting specific mediators involved in the pathogenesis of AD were found. These targets include IL-4, IL-13, IgE, B-cells, IL-5, IL-31, JAK-STAT, SYK, IL-6, PDE-4, IL-12, IL-17, IL-23, IL-22, H4R, NKR1, κOR, TSLP, PPAR-γ, and DGLA. Treatment of AD patients with these therapies has, in many cases, led to statistically significant improvements in clinical severity scores and patient-reported outcomes. Conclusions: While multiple agents have demonstrated efficacy, only dupilumab is currently approved for adults with AD. Large-scale, randomized, placebo-controlled, double-blind trials, especially in children, are needed. As we enter the dawn of targeted therapy for AD, a comprehensive clinical trial registry is needed to facilitate data pooling and comparison among international registries. [ABSTRACT FROM AUTHOR]

Skin disease and its therapy affect health-related quality of life (HRQoL). The aim of this study was to measure the burden caused by dermatological therapy in 3,846 patients from 13 European countries. Adult outpatients completed questionnaires, including the Dermatology Life Quality Index (DLQI), which has a therapy impact question. Therapy issues were reported by a majority of patients with atopic dermatitis (63.4%), psoriasis (60.7%), prurigo (54.4%), hidradenitis suppurativa (54.3%) and blistering conditions (53%). The largest reduction in HRQoL attributable to therapy, as a percentage of total DLQI, adjusted for confounders, was seen in blistering conditions (10.7%), allergic/ drug reactions (10.2%), psoriasis (9.9%), vasculitis/ immunological ulcers (8.8%), atopic dermatitis (8.7%), and venous leg ulcers (8.5%). In skin cancer, although it had less impact on HRQoL, the reduction due to therapy was 6.8%. Treatment for skin disease contributes considerably to reducing HRQoL: the burden of dermatological treatment should be considered when planning therapy and designing new dermatological therapies.

Psoriasis and atopic dermatitis patients show an excessive amount of elastase in peripheral blood neutrophils due to an imbalance between this proteolytic enzyme and its endogenous inhibitors, the search for new human neutrophil elastase (HNE) inhibitors are required. The HNE is an attractive therapeutic target and inhibitors with new molecular architectures have been extensively investigated. In this context a promising novel synthetic human neutrophil elastase inhibitor (ER143) was associated to a starch-based nanoparticulate system (StNC) with improved pharmaceutical performance, using a quality by design approach to support product development and optimization. The resulting formulation was characterized in terms of and in vitro release, permeation and retention studies in newborn pig skin, using Franz diffusion cells revealing the StNC have the ability to control the drug release rate and contribute to a high skin retention and/or permeation profiles. The anti-inflammatory activity accessed in vivo using the croton oil-induced ear inflammation model in mice showed that erythema and edema were attenuated in 98% following local application. These observations suggest the association of ER143 to the StNC promotes a deeper skin penetration and retention, also confirming StNC as a potential topical delivery system. [ABSTRACT FROM AUTHOR]

Introduction: Microbial infection and associated super antigens have been implicated in the pathogenesis of cutaneous T-cell lymphoma (CTCL), and many patients die from complicating bacterial infections. It has been postulated that Chlamydophila pneumoniae (C. pneumoniae) infection may be involved in the pathogenesis of Mycosis fungoides (MF) but published data are limited and controversial. Aim: To analyze the frequency of (C. pneumoniae) DNA presence in blood samples of lymphoma cases. Material and methods: Using Q-PCR method we analyzed the presence of DNA in the blood samples obtained from 57 patients with CTCL (55 - mycosis fungoides (MF)/Sézary syndrome (SS), one primary cutaneous anaplastic large cell lymphoma (CD30+) and one NKT cell lymphoma) and 3 patients with cutaneous B-cell lymphomas, and 120 individuals from control groups (40 patients with psoriasis, 40 patients with atopic dermatitis and 40 healthy controls). Results: Chlamydophila pneumoniae DNA was identified in 13 of 55 cases in the MF/SS group (23.6%), in 1 patient with CD30+ large cell lymphoma and in 1 of 3 patients with B-cell lymphoma. The presence of C. pneumoniae was confirmed in 1 of 40 psoriatic patients (2.5%), in 5 of 40 patients with atopic dermatitis (12.5%) and in none of 40 healthy individuals. Presence of C. pneumoniae DNA in MF patients was strongly associated with disease progression; rs = 0.756; p = 0.0123 for groups IA → IVB, and was noted more frequently in advanced (III + IV) stages than in early (I-II) stages (p = 0.0139). There are no differences in the mean age of MF/SS patients with and without infection. Conclusions: The presence of C. pneumoniae DNA in the blood cells is a frequent event in late stages of MF/SS and may be explained by Th2 shift and suppression of the immune system during the course of the disease.

Abstract: Background/Objectives: Atopic dermatitis (AD) is a common condition affecting up to 20% of the paediatric population in Singapore. It is often associated with significant psychosocial morbidity and can affect patients' quality of life (QOL) tremendously. This study investigated the varying lifestyle impacts, and psychosocial domains most affected by AD in adolescent children in Singapore. Methods: A prospective study evaluating the impact of AD on the QOL of adolescents was conducted over a 6‐month period from July to December 2014. Adolescents aged 11–16 years with varying eczema severity were recruited. Eczema severity was determined by using the eczema area and severity index (EASI) scores. Lifestyle impact of AD was evaluated using patient‐reported children's dermatology life quality index (CDLQI) scores. Statistical analysis was performed using an analysis of one‐way variance and Student's t‐test. Results: A total of 50 patients were enrolled and divided into three groups: mild (<10.3), moderate (10.3–20.9) and severe (>20.9) eczema based on EASI scores. Patients with mild and moderate eczema had lower CDLQI scores. Adolescents were most affected by the disruption that their symptoms had on their leisure and physical activities and sleep as a result of itch and scratching, respectively. Conclusion: Chronic sufferers of severe eczema experience poorer QOL than those with mild or moderate eczema. They also experience significant psychosocial impact as a consequence of their condition.

Abstract: Atopic dermatitis (AD) is a common, highly pruritic, chronic inflammatory skin disease. Dysfunction of the epidermal barrier is witnessed by an increased transepidermal water loss in lesional and non‐lesional AD skin. The inflammation in lesional AD skin is well characterized. Non‐lesional skin of AD patients shows histological signs of a subclinical inflammation and a pro‐inflammatory cytokine milieu. This microinflammation is present even in seemingly healed skin and must be taken into account regarding treatment of AD. Emollients provide a safe and effective method of skin barrier improvement, because they provide the skin with a source of exogenous lipids, thus improving its barrier function. The use of emollients is recommended for all AD patients irrespective of overall disease severity. Patients with moderate to severe AD should combine the emollients with a proactive therapy regimen of topical calcineurin inhibitors or topical corticosteroids. Skin areas affected by active eczema in flare should receive daily anti‐inflammatory therapy first before introducing emollients, to induce rapid relief of skin lesions and pruritus. The microinflammation persisting in seemingly healed AD lesions should be addressed by a proactive treatment approach, consisting of minimal anti‐inflammatory therapy and liberal, daily use of emollients. An emollient containing an extract of Rhealba oat plantlet has shown anti‐inflammatory and barrier repairing properties, and was clinically tested in studies targeting the microinflammation in AD. All emollients based on Rhealba oat plantlet extract are free of oat protein, as the Rhealba extract is derived from the aerial parts of the oat plantlet and is unrelated to oatmeal proteins. The Rhealba oat plantlet extract is produced in a specific process, allowing the extraction of high levels of active principles such as flavonoids and saponins, whilst being virtually free of oat proteins to minimize the risk for allergic reactions.

Background: Staphylococcus aureus skin colonization is common in patients with atopic dermatitis (AD) and is associated with risk of skin infections. AD patients therefore often receive antibiotic treatments, including topical treatment with fusidic acid, which have been associated with resistance development. Objectives: To examine the prevalence of antibiotic resistance in S. aureus isolated from Danish AD patients, with a primary focus on fusidic acid resistance and the genetic mechanisms that underlie it. Methods: One hundred and thirty-eight S. aureus isolates collected from lesional skin (n = 54), non-lesional skin (n = 27) and anterior nares (n = 57) from 71 adult AD patients were included in the study. Isolates were tested for susceptibility to 17 selected antibiotics. S. aureus whole-genome sequences were used to examine the genetic determinants of fusidic acid resistance (fusA or fusE mutations or carriage of fusB or fusC genes). Results: One hundred and nine isolates (79%) were resistant to at least one of the tested antibiotics, with the most prevalent resistances being to penicillin (55%), fusidic acid (41%) and erythromycin (11%). The primary genetic mechanisms of fusidic acid resistance were carriage of fusC (57%) or mutations in fusA (38%). The most prevalent S. aureus lineage was ST1 (23%). All ST1 isolates carried fusC. Conclusions: S. aureus fusidic acid resistance, caused by either fusA mutations or fusC gene carriage, is a major concern among AD patients. Resistant S. aureus might spread from the patients to the community, indicating the need to reduce the use of fusidic acid in the treatment of AD. [ABSTRACT FROM AUTHOR]

Abstract: Atopic dermatitis (AD) is a chronic and multifactorial inflammatory skin disease involving various dendritic cells such as epidermal Langerhans cells (LC) and inflammatory dendritic epidermal cells (IDECs). Most of the clinical studies was performed on isolated cells, and thus, it would be useful to characterize directly on the human epidermal tissue the first cellular events occurred during the AD. The suction blister method was used to obtain whole epidermis samples and interstitial cutaneous fluids. Employing multiphoton microscopy, we analyzed the early dynamic behavior of inflammatory cells using
Dermatophagoides pteronyssinus atopy patch test (Derp‐APT) and evaluated the effects of emollient pre‐application. Derp‐APT application provoked rapid and strong infiltration of IDECs, and proliferation and activation of LC in the AD subjects’ epidermis. Moreover, emollient pre‐application strengthened the defective skin barrier and had positive effects on inflammatory cells’ behavior, characterized by the complete inhibition of IDEC influx and the presence of immature LC.

Abstract: Atopic dermatitis (AD) is a chronic inflammatory skin condition that affects diverse ethnic groups with varying prevalence. Despite a predominance of studies in individuals of European ancestry, AD has been found to occur more frequently in Asian and Black individuals than Whites. Therefore, an understanding of the unique clinical features of AD in diverse ethnic groups, as well as the differences in genetic polymorphisms that influence susceptibility to AD and response to current therapies, is paramount for management of an increasingly diverse patient population. In this article, we review key nuances in the epidemiology, pathophysiology, clinical presentation and treatment of AD in non‐White ethnic groups, which are largely underappreciated in the literature. We highlight the need for studies evaluating the tissue molecular and cellular phenotypes of AD in non‐White patients, as well as greater inclusion of minority groups in clinical trials, to develop targeted treatments for a multi‐ethnic population.

Abstract:
Staphylococcus aureus colonization is thought to contribute to the pathophysiology of atopic dermatitis (AD). AD patients exhibit reduced levels of cutaneous antimicrobial peptides (AMPs), which may explain their increased susceptibility to infections. Using an in vitro reconstructed human epidermis (RHE) model, we sought to determine whether topical application of a non‐replicating probiotic, heat‐treatedLactobacillus johnsonii NCC 533 (HT La1), could inhibitS. aureus adhesion to skin and boost cutaneous innate immunity. We found that application of HT La1 suspension to RHE samples reduced the binding of radiolabelledS. aureus by up to 74%. To investigate a potential effect of HT La1 on innate immunity, we analysed the expression of nine AMP genes, including those encoding beta defensins and S100 proteins, following topical application of HT La1 in suspension or in a daily moisturizer lotion. Analysed genes were induced by up to fourfold in a dose‐dependent manner by HT La1 in suspension and by up to 2.4‐fold by HT La1 in the moisturizer lotion. Finally, using ELISA and immunohistochemical detection, we evaluated the expression and secretion of the AMPs hBD‐2 and psoriasin and determined that both proteins were induced by topical HT La1, particularly in the stratum corneum of the RHE. These findings demonstrate that a topically applied, non‐replicating probiotic can modulate endogenous AMP expression and inhibit binding ofS. aureus to an RHE model in vitro. Moreover, they suggest that a topical formulation containing HT La1 could benefit atopic skin by enhancing cutaneous innate immunity and reducingS. aureus colonization.

Abstract: With the recent availability of culture‐independent sequencing methods, studies have been conducted to analyse skin micro‐organisms present in patients with atopic dermatitis (AD). However, the database on the skin fungal communities, “mycobiome,” has been relatively restrictive compared with the bacterial world. We aimed to comparatively analyse the overall skin mycobiome between patients with AD and healthy individuals in the Korean population. We analysed skin swab samples obtained from the antecubital fossae of 8 patients with AD and 8 healthy controls. Using sequencing method followed by direct DNA extraction and molecular PCR, taxonomic compositions of fungi at stepwise level ranks were analysed. The phylogenic marker used was internal transcribed spacer 2 regions of DNA. We observed the tendency of higher intra‐ and interpersonal taxonomic diversity at genus and species levels in AD samples. Non‐
Malassezia fungal diversity was also noticeable in the patient group compared with healthy controls.Malassezia globosa andMalassezia restricta were prevalent in all samples across both study groups, and someMalassezia species, includingMalassezia sloofiae andMalassezia dermatis, characterized AD. Our data might provide a new insight into the mycobiome of adult AD, which contributes to building a systemic mycobiome database in AD. [ABSTRACT FROM AUTHOR]- Published

Abstract: Although atopic dry skin is believed to be caused by defects in skin genes important for maintaining skin barrier function, the role of sweat in atopic dermatitis (AD) has been apparently underestimated. Given the great capacity of sweat to maintain and increase skin hydration, defective sweating responses may be a logical place to look for changes that predispose individuals to the disease. We investigated how disease process and sweating defects progress from early asymptomatic stages to the onset of clinically apparent disease by employing the impression mould technique, which allows an accurate quantification of individual sweat gland/duct activity in relation to skin surface topography. Insensible and sensible sweating responses under baseline conditions and after thermal stimulus, respectively, were measured in various stages of AD patients and healthy controls. In controls, under baseline conditions, sweat ducts/glands at the dermal folds secreted basal levels of sweat (insensible sweating), thereby maintaining skin hydration. Not only such insensible sweating but also sensible sweating markedly decreased even in the earliest asymptomatic stage and the decrease was followed by compensatory hyperhidrosis at the ridge: leakage of sweat into the dermis could represent the initial event resulting in the decreased sweating and inflammation. The defects eventually progressed involving all of the ducts/glands to develop systemic dry skin. AD skin is characterized by varying degrees of functional impairment of sweat ducts/glands depending on the stage, and this defect would be among the reasons for the inability of AD patients to maintain skin hydration.

Background:Patients tend to apply topical medications less frequently, in improper amounts. Not only frequency but also application amount may influence treatment outcome. However, studies on relationship between application amount and objective treatment outcome have rarely been conducted. Objective:To assess efficacy of topical agent according to application amount in adult patients, using the finger-tip unit method. Methods:The efficacy of 0.1% topical tacrolimus in adult patients with localised atopic dermatitis was assessed using EASI, TIS, IGA, and PGA scores at baseline, follow-up. Adherence in amount was evaluated after 2 weeks of treatment using the ratio of the actual amount applied to the expected amount applied (A/E). Results:Twenty-seven patients (20.93%) used topical tacrolimus in proper amounts (A/E: 0.8–1.2). However, 86 patients (66.67%) underused topical tacrolimus; 16 (12.40%) patients overused topical tacrolimus. Decreases in EASI scores between baseline and 2 weeks of follow-up in each group (under-amount, proper amount, over-amount) were 1.64, 4.65 and 4.21, respectively. Treatment efficacy increased in accordance with application amount. Further, TIS, IGA, PGA, VAS for Itch and DLQI scores improved concomitantly, exhibiting similar tendencies. Conclusion:Application amount of topical agent is important in increasing treatment efficacy in adult patients with atopic dermatitis. [ABSTRACT FROM PUBLISHER]

The rising prevalence of food allergy and specifically peanut allergy has had significant implications for affected patients, families, and society. The current standard of care remains strict avoidance and the use of emergency medications for accidental ingestions. There is recent evidence-based information to suggest that one approach to preventing peanut allergy lies in early introduction of peanut. This represents a paradigm shift from previous recommendations and has led to updated guidelines in the United States, Europe, and Australasia on the introduction of potentially allergenic foods in the infant diet. This new approach to prevention has some practical obstacles and challenges associated with its implementation. There is also growing interest in the role of maintaining a healthy skin barrier in prevention of sensitization and food allergy. Other approaches, including pro- and prebiotics, prenatal maternal dietary avoidance, breastfeeding, and the use of specific formulas, have not shown reproducibly favorable results. As children with peanut allergy are unlikely to outgrow their food allergy, early oral immunotherapy in those with established peanut allergy is being investigated with the hopes of altering the natural history of an otherwise lifelong disease.

Atopic dermatitis (AD), a common childhood skin disorder, can limit a child's learning and physical activities. South Korean mothers, as primary caregivers, experience anxiety and helplessness when caring for their ill children. The aim of this study was to develop a hybrid AD education programme (consisting of a face-to-face session followed by 8 online sessions) and evaluate its effects on anxiety, caregiving efficacy and caregiving behaviour among mothers of children with AD. Twenty mothers of patients with AD treated in a South Korean hospital received one on-site session and 8 weekly online modules. After the intervention, mothers' mean ± standard deviation anxiety reduced (from 50.3 ± 14.2 to 31.7 ± 6.3 points, t = 5.75, p < 0.001). Their caregiving efficacy and caregiving behaviour improved significantly, from 18.3 ± 3.5 to 29.4 ± 3.2 points (t = -9.64, p < 0.001) and from 47.7 ± 7.7 to 78.8 ± 4.9 points (t = -14.4, p < 0.001), respectively. The effects of the hybrid education programme for this population were significant. Healthcare providers should consider examining the programme nationwide, including in rural areas, while investigating its long-term effects. [ABSTRACT FROM AUTHOR]

Atopic dermatitis (AD) is a chronic, itchy, inflammatory skin disorder that may worsen due to stress and anxiety. Tachykinins have been suggested to be involved in the inflammation in AD, as well as pruritus. Aprepitant is a NK-1 receptor antagonist. This open randomized trial evaluated the effect of aprepitant added to topical treatment in adult patients with moderate-severe AD. The treatment group (n = 19) received 80 mg/day aprepitant for 7 days as a supplement to standardized topical treatment with a moderately strong steroid and a moisturizer. The control group (n = 20) received topical treatment alone. Patients were monitored for the extent of the disease (using SCORing of Atopic Dermatitis; SCORAD), pruritus, and scratching movements. In both the aprepitant-treated and the control groups there was a decrease in SCORAD, pruritus and scratching movements. However, there was no significant additional improvement in any of these parameters in the aprepitant-treated group compared with the control group. [ABSTRACT FROM AUTHOR]

Abstract: Background: Children with early‐onset atopic dermatitis (AD) are at substantial risk of developing asthma later in life, and identifying the critical window of detrimental exposure is advantageous for implementing preventive actions. The aim of this study was to evaluate the role of exposure to environmental modifiers during pregnancy and early childhood in asthma occurrence in an infantile AD cohort. Methods: Eligible study participants were selected from the Taiwan Birth Cohort Study, which enrolled 24 200 newborns in 2005. We enrolled those cases who had been diagnosed as having AD before 3 years of age and followed them up till age 8. We excluded those ever diagnosed with asthma before AD onset. The dependent variable was defined in terms of whether the participant was diagnosed as having asthma before 8 years of age. We applied logistic regression models to evaluate the risks of exposure to different determinants in asthma occurrence. Results: A total of 1549 children with AD had completed the 8‐year follow‐up, and 334 (21.6%) of them had asthma. The results revealed that male sex, lower birth order, maternal asthma history, maternal obesity before pregnancy, and environmental tobacco smoke exposure before 3 years of age were significant risk factors for further development of asthma. Furthermore, food allergy during early life, lower respiratory tract infection, and longer durations of symptomatic AD influenced asthma development later in life. Conclusions: The findings confirmed the critical determinants for asthma occurrence in infantile AD, which may enable a more personalized approach to the prevention of asthma. [ABSTRACT FROM AUTHOR]

Abstract: Background: Prenatal folic acid supplementation is recommended to prevent birth defects. Some foods are fortified in the USA to ensure sufficient intake among reproductive‐aged women. However, high prenatal folate exposure may be a risk factor for childhood atopic diseases. We investigated associations between prenatal folate and early childhood wheeze and atopic dermatitis in a US cohort. Methods: We studied 858 mother‐child dyads, enrolled prenatally. Folate was measured in 2nd and 3rd trimester maternal plasma. Parents reported current wheeze (previous 12 months) and healthcare provider diagnosis of atopic dermatitis at 3 years. We examined associations using logistic regression, modeling folate continuously and dichotomously (< or ≥20 ng/mL), a level often considered supraphysiologic. Results: Over half of women were African American and on Medicaid. Median (interquartile range) folate levels were 22.6 (15.9‐30.0) and 23.1 (16.1‐30.0) ng/mL for 2nd and 3rd trimesters, respectively. Current wheeze and atopic dermatitis were reported for 20.4% and 26.8% of children, respectively. Second trimester folate as a continuous exposure was not significantly associated with outcomes. Decreased odds of current wheeze were observed in children born to mothers who had 2nd trimester folate ≥20 ng/mL (adjusted odds ratios = 0.67, 95% confidence interval = 0.46, 0.97) compared to children with maternal levels <20 ng/mL. Third trimester folate was not associated with outcomes. Conclusions: High plasma folate in mid‐pregnancy was associated with decreased odds of current wheeze at age 3. Our findings do not support harmful effects of high prenatal folate levels on childhood atopic diseases in this setting. [ABSTRACT FROM AUTHOR]

Summary: The aim of this study was to evaluate if there is some relation between the sensitisation to fungi and the occurrence of food hypersensitivity reactions in atopic dermatitis patients aged 14 years and older. Complete dermatological and allergological examination was performed in all included patients; the occurrence of food hypersensitivity reactions was recorded and the sensitisation to mixture of fungi was examined (skin prick test, specific IgE). The statistical evaluation of the relation between the sensitisation to fungi and the occurrence of food hypersensitivity reactions was performed; 331 patients were included in the study, 110 men and 221 women, the average age was 26.8 years. The sensitisation to fungi was recorded in 100 patients (30%), the occurrence of food hypersensitivity reactions was recorded in 261 patients (79%). We confirmed that patients suffering from sensitisation to fungi suffer significantly more often from food hypersensitivity reactions to nuts (walnuts, peanuts) and sea fish; no significant relation was confirmed between the sensitisation to fungi and the occurrence of food hypersensitivity reactions to tomatoes, kiwi, apples, spices, oranges, capsicum, celery and carrot.

Background: Oral immunosuppressive drugs are frequently prescribed in young women with atopic dermatitis (AD). Immunocompromised patients may have a higher risk of developing high-risk HPV infections, cervical intra-epithelial neoplasia (CIN) and cervical carcinoma. Most literature on patients using oral immunosuppressive drugs is available in organ transplant patients. Literature on the risk of developing cervical carcinoma in AD patients treated with oral immunosuppressive drugs is lacking. At this moment, there is no clear guideline/consensus on this topic, but in daily practice, questions arise concerning whether this risk is increased and whether more intensive screening in women using immunosuppressive drugs should take place. Objective: To investigate the occurrence of cervical carcinoma in women with AD treated with oral immunosuppressive drugs. Methods: In this retrospective cohort study in two university medical centres in the Netherlands, all female adult AD patients receiving oral immunosuppressive drugs (cyclosporine A, azathioprine, methotrexate, mycophenolate mofetil, enteric-coated mycophenolate sodium and extended release tacrolimus) for more than 2 months between 1989 and 1 January 2014 were included. Patient files in the national histopathology register were screened for PAP3a, CIN I, CIN II, CIN III and cervical carcinoma. Results: A total of 257 female AD patients with one or more treatment episodes from 1989 until 1 January 2014 were identified and included in this study. In 189 patients (73.5%), results of cervical examination were reported in the national histopathology database. Median total duration of treatment in these 189 women was 407.0 days (IQR 243.0–940.0). No cervical carcinoma during or following immunosuppressive therapy was found in our patient group. Conclusions: No intensified screening programme for cervical neoplasia seems necessary for women with AD using oral immunosuppressive drugs. [ABSTRACT FROM AUTHOR]

Summary:
Background : JTE‐052 is a novel Janus kinase inhibitor presently under clinical development for the topical treatment of atopic dermatitis (AD).Objectives : To evaluate the efficacy and safety of JTE‐052 ointment in Japanese adult patients with AD.Methods : Patients with moderate‐to‐severe AD were randomized (2: 2: 2: 2: 1: 1) to receive JTE‐052 ointment at 0·25%, 0·5%, 1% or 3%, the vehicle ointment or tacrolimus 0·1% ointment (reference) twice daily for 4 weeks. The primary efficacy end point was the percentage change in modified Eczema Area Severity Index (mEASI) score from baseline at the end of treatment (EOT). Secondary efficacy end points included change from baseline in the pruritus numerical rating scale (NRS) score.Results : In total, 327 patients were enrolled. At EOT, the least‐squares mean percentage changes from baseline in mEASI score for JTE‐052 at 0·25%, 0·5%, 1% and 3% and the vehicle ointment were −41·7%, −57·1%, −54·9%, −72·9% and −12·2%, respectively. All JTE‐052 groups showed significant reductions of mEASI score vs. the vehicle group (P < 0·001 for all). In the tacrolimus group, the mean percentage change in mEASI score was −62·0%. The JTE‐052 groups also showed significant improvement in other parameters; notably, the pruritus NRS score was reduced as early as day 1 night‐time. JTE‐052 ointment at doses up to 3% was safe and well tolerated.Conclusions : Topical JTE‐052 markedly and rapidly improved clinical signs and symptoms in Japanese adult patients with moderate‐to‐severe AD, with a favourable safety profile. The study results indicate that topical JTE‐052 is a promising therapeutic option for AD. The trial registration number is JapicCTI‐152887. [ABSTRACT FROM AUTHOR]- Published

Summary: Background: Dupilumab, a human anti‐interleukin‐4 receptor alpha monoclonal antibody, significantly improved clinical signs and symptoms in adults with moderate‐to‐severe atopic dermatitis in a randomized, double‐blind, placebo‐controlled, phase IIa trial. Objectives: We evaluate health‐related quality of life (HRQoL) and correlation of HRQoL with secondary clinical and patient‐reported outcomes in a subset of patients from this trial of dupilumab. Methods: Patients were randomized to 300 mg weekly subcutaneous dupilumab or placebo for 12 weeks (trial registration: NCT01548404). The Quality of Life Index of Atopic Dermatitis (QoLIAD) score (exploratory outcome) and its correlation with efficacy outcomes [Eczema Area and Severity Index (EASI); primary end point; SCORing Atopic Dermatitis (SCORAD), SCORAD visual analogue scale (VAS) scores for sleep and pruritus, pruritus numerical rating scale (NRS) and 5‐dimensional pruritus] were assessed in 64 adults with moderate‐to‐severe atopic dermatitis. Results: Mean QoLIAD scores at baseline ± standard error (SE) were 13·3 ± 1·34 and 11·3 ± 1·09 for the placebo and dupilumab groups, respectively. Dupilumab significantly improved QoLIAD score after 12 weeks of treatment vs. placebo (mean % change from baseline in QoLIAD score ± SE: −64·0 ± 6·91 vs. –11·1 ± 9·31). Least squares mean % difference from baseline vs. placebo in QoLIAD score ±SE was −52·0 ± 11·43,
P < 0·001). QoLIAD scores significantly correlated with changes in efficacy outcomes, including EASI (r = 0·44), 5‐dimensional pruritus (r = 0·49), pruritus NRS (r = 0·41), total SCORAD (r = 0·56) and SCORAD VAS scores for sleep (r = 0·47) and pruritus (r = 0·54); allP < 0·05. Conclusions: Dupilumab improved QoLIAD scores in adults with atopic dermatitis and was significantly associated with improvements in study outcomes. [ABSTRACT FROM AUTHOR]- Published

Introduction: Staphylococcus aureus causes a diverse array of diseases, ranging from relatively harmless localized skin infections to life-threatening systemic conditions. It secretes toxins directly associated with particular disease symptoms. Aim: To determine the prevalence of methicillin-resistant S. aureus (MRSA) and methicillin-susceptible S. aureus (MSSA) colonization among patients with atopic dermatitis and to assess the antimicrobial susceptibility to conventional antibiotics and selected antimicrobial peptides among toxin-producing strains and nonproducing strains. Material and methods: One hundred patients with atopic dermatitis and 50 healthy people were microbiologically assessed for the carriage of S. aureus. Antimicrobial susceptibility tests were performed using the broth microdilution method for conventional antibiotics and antimicrobial peptides (CAMEL, Citropin 1.1, LL-37, Temporin A). Detection of genes lukS/lukF-PV, tst, sea-sed, eta and etb by multiplex PCR was performed. Results: Staphylococcus aureus strains were isolated from the majority of patients, from either the skin (75%) or the anterior nares (73%). Among the conventional antibiotics tested, the highest rates of resistance were observed for ampicillin, daptomycin, lincomycin and erythromycin. Antimicrobial peptides did not show significant diversity in activity. Among MSSA strains greater differentiation of secreted toxins was observed (sec, eta, pvl, tsst, etb, seb), while in the group of MRSA strains secretion of 3 toxins (pvl, eta, seb) was noted. Conclusions: Antimicrobial resistance continues to evolve. It is important to monitor S. aureus infections. The profile of toxins produced by S. aureus strains is an important consideration in the selection of an antimicrobial agent to treat infections. [ABSTRACT FROM AUTHOR]

Atopic dermatitis is a chronic, recurrent inflammatory skin disease, which is frequently familial. The main cause of the disease seems to be a defect of the epidermal barrier resulting from a genetic predisposition concerning the epidermis, functioning of the immune system as well as environmental factors (which are not related to the immune system). Genes responsible for encoding protein S100, filaggrin, proteases and their inhibitors are the main genes related to the problem of epidermal barrier dysfunction. There is a close connection between structural and immunological processes. Increased expression of cytokine Th2 profile belongs to the latter category. The objective of the present paper is to describe the influence of aforementioned factors on epidermis structure and dysfunction which leads to clinical symptoms of atopic dermatitis.
