Abstract
Food allergy is a major health concern worldwide, encompassing both immunologic and non-immunologic reactions. This review thoroughly examines the pathophysiology, clinical manifestations, and treatment options for various types of food allergies. Immunologic food allergies, including IgE-mediated reactions such as oral allergy syndrome and systemic anaphylaxis, pose various diagnostic and management challenges. Non-IgE-mediated reactions such as food protein-induced enterocolitis syndrome, dermatitis herpetiformis, and proctocolitis necessitate individualized patient care. In addition, mixed reactions such as eosinophilic esophagitis and atopic dermatitis complicate the clinical picture. Skin prick tests, serum-specific IgE tests, and oral food challenges are all necessary for accurate food allergy diagnosis. The primary therapeutic options are allergen avoidance, epinephrine-based emergency management, and emerging treatments like immunotherapy. Our review emphasizes the importance of multidisciplinary collaboration and ongoing research in improving our understanding and managing food allergies, promising a brighter future for those affected.

Abstract
Background: There is a lack of studies about which factors affect the quality of life (QoL) in children with atopic dermatitis (AD), although it is well known that AD has considerably negative effects on their QoL. Objective: This study aimed to measure the QoL in children with AD and identify the factors that affect their QoL. Methods: A questionnaire derived from the Children's Dermatology Life Quality Index (CDLQI) was used to measure QoL. Family history, allergic comorbidities, exacerbation-related factors, time of exacerbation, and previous and current treatment were also evaluated. The total immunoglobulin E (IgE) level and specific IgE sensitization were determined by the multiple allergen simultaneous test, allergy test, or skin-prick test. AD severity was categorized into mild, moderate, and severe based on treatments. Results: In total, 254 children (46.4 months, 53% boys) from seven hospitals completed the survey. The mean CDLQI score was 7.2 ± 5.5 (total score range of 0-30). The respondents were divided into three groups according to their QoL score distribution, with 0 - 4 points (n = 84), 5 - 9 points (n = 90), and ≥10 points (n = 80) representing good, fair, and poor QoL, respectively. The more severe AD showed the higher CDLQI score significantly (p = 0.001). Compared with other groups, children with poor QoL were more sensitized to inhalant allergens (odds ratio [OR] 1.29 [95% confidence interval {CI}], 1.03 - 1.62) and had more exacerbating factors (OR 1.26 [95% CI, 1.04 - 1.54]), which included inhalation allergen-related exacerbating factors (OR 2.54 [95% CI, 1.23 - 5.23), even after adjusting for age, total IgE, body mass index, severity, and use of moisturizer. The concordance between animal sensitization and an exacerbating factor, including dog and cat, was fair, with 0.39 κ and 0.85 accuracy. Conclusion: This study showed that impaired QoL in children with AD is associated with inhalant allergen sensitization and inhalant allergen-related exacerbation factors. Especially, dog and cat sensitization was a significant exacerbating factor. The inhalation-related exacerbation factors, including animal allergens, might be addressed to improve AD management in children.

Abstract
Atopic dermatitis (AD) is one of the most common, bothersome and difficult to treat skin disorders. Recent introduction of new systemic treatments has revolutionized the management of AD. The goal of this guideline is to provide evidence-based recommendations for the management of patients suffering from atopic dermatitis that easily can be implemented in clinical practice. These recommendations were developed by 11 Belgian AD experts. Comments of all experts on the proposed statements were gathered, followed by an online voting session. The most relevant strategies for the management and treatment of AD in the context of the Belgian health care landscape are discussed. General measures, patient education and adequate topical treatment remain the cornerstones of AD management. For moderate to severe AD, the introduction of biologics and JAK inhibitors show unprecedented efficacy, although currently access is limited to a subgroup of patients meeting the reimbursement criteria.

SISLI ETFAL HASTANESI TIP BULTENI 2023; 57:403-409. [PMID: 37900332 PMCID: PMC10600614 DOI: 10.14744/semb.2023.21298] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 08/06/2023] [Revised: 08/08/2023] [Accepted: 08/10/2023] [Indexed: 10/31/2023]
Abstract
Objectives In this study, it was aimed to examine food sensitivity in patients with atopic dermatitis (AD) and to investigate the frequency of food allergy in patients with food sensitivity. Methods Patients aged 0-2 years who were followed up with the diagnosis of AD were included in the study. The characteristics of demographic and clinical and laboratory findings of the patients were recorded retrospectively. Patients were classified as mild, moderate, and severe using the SCORing AD index according to the severity of AD. The presence of food sensitivity was evaluated by skin prick test and serum-specific immunoglobulin (Ig)E results. Food allergy was diagnosed by oral food challenge (OFC) test. Results Of the 72 patients included in the study, 62.5% (n=45) were male, and the mean age was 9±4.8 months. When the disease severity was evaluated, it was mild in 40 patients (55.6%); moderate/severe AD was present in 32 patients (44.4%). The frequency of moderate/severe AD was higher in patients who were younger (p=0.01), whose symptoms started in the first 6 months (p=0.03), who had a family history of allergic disease (p=0.001), who breastfed for <6 months (p=0.01), who had a higher median serum total IgE level, and a higher percentage of serum eosinophils (p=0.005 and p=0.01, respectively). Food sensitivity in 45.8% of patients; food allergy was detected in 41.7% of them. The most common sensitivities and allergies were eggs white/yolk and cow's milk, respectively. The rate of food sensitivity was found to be higher in male gender (p=0.03) and breastfed patients (p=0.03), whereas it was similar in patients with mild and moderate/severe AD. Conclusion In the investigation of food sensitivity in patients with AD, it is important to evaluate other demographic and clinical characteristics such as gender and breastfeeding, apart from the severity of disease. The OFC test should be performed to confirm the food allergy in patients with food sensitivity before the recommendation of an elimination diet.

Improvements in Gut Microbiome Composition Predict the Clinical Efficacy of a Novel Synbiotics Formula in Children with Mild to Moderate Atopic Dermatitis. Microorganisms 2023; 11:2175. [PMID: 37764019 PMCID: PMC10536305 DOI: 10.3390/microorganisms11092175] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/09/2023] [Revised: 08/21/2023] [Accepted: 08/23/2023] [Indexed: 09/29/2023] Open
Abstract
Atopic dermatitis (AD) is a common chronic inflammatory skin disease with a significant association with various type-2 inflammation-related comorbidities. Ongoing research suggests the crucial involvement of gut microbiome, especially in childhood onset AD, and hence, probiotics have emerged as a potential non-steroid-based therapeutics option to complement existing AD management plans. In order to delineate the impact of probiotics in the gut microbiome of pediatric AD patients from southern China, targeted 16S rRNA sequencing and thorough bioinformatic analysis were performed to analyze the gut microbiome profiles of 24 AD children after taking an orally administered novel synbiotics formula with triple prebiotics for 8 weeks. A notable improvement in Eczema Area and Severity Index (EASI) (p = 0.008) was observed after taking an 8-week course of probiotics, with no adverse effects observed. The relative abundances of key microbial drivers including Bacteroides fragilis and Lactobacillus acidophilus were significantly increased at week 8. We also found that the positive responsiveness towards an 8-week course of probiotics was associated with improvements in the gut microbiome profile with a higher relative abundance of probiotic species. Over-represented functional abundance pathways related to vitamin B synthesis and peptidoglycan recycling may imply the underlying mechanism. In summary, our study suggests how the gut microbial landscape shifts upon probiotic supplementation in AD children, and provides preliminary evidence to support targeted probiotic supplementation for the management of childhood AD.

Eur J Pediatr 2023:10.1007/s00431-023-04961-x. [PMID: 37041294 DOI: 10.1007/s00431-023-04961-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/14/2022] [Revised: 03/22/2023] [Accepted: 03/30/2023] [Indexed: 04/13/2023]
Abstract
Eosinophilia is common in children and may be caused by various disorders. Large-cohort studies, including mild cases, are limited in children. This study aimed to reveal underlying etiologies of childhood eosinophilia and to create a diagnostic algorithm. Children (< 18 years) with absolute eosinophil counts (AECs) ≥ 0.5 × 109/L were reviewed from medical files. Clinical characteristics and laboratory values were recorded. Patients were grouped based on the severity of eosinophilia as mild (0.5-1.5 × 109/L), moderate (≥ 1.5 × 109/L) and severe (≥ 5.0 × 109/L). An algorithm was formed to evaluate these patients. We included 1178 children with mild (80.8%), moderate (17.8%) and severe eosinophilia (1.4%). The most common reasons of eosinophilia were allergic diseases (80%), primary immunodeficiency (PID) (8.5%), infectious diseases (5.8%), malignancies (0.8%) and rheumatic diseases (0.7%). Only 0.3% of children presented with idiopatic hypereosinophilic syndrome. Allergic diseases and PIDs were the most common etiologies in mild/moderate and severe groups, respectively. The median duration of eosinophilia was 7.0 (3.0-17.0) months in the study population and was the shortest in severe cases (2.0 (2.0-5.0) months). Multiple logistic regression analysis demonstrated food allergy [OR:1.866, 95%CI:1.225-2.842, p = 0.004] and PIDs [OR:2.200, 95%CI:1.213-3.992, p = 0.009] as independent factors for childhood eosinophilia. A diagnostic algorithm including mild form was presented for childhood eosinophilia. Conclusion: Eosinophilia was frequently determined due to secondary causes; allergic diseases in mild/moderate eosinophilia, PIDs in severe group. Etiology of eosinophilia was diverse, and an algorithm concerning the severity of eosinophilia would be practical and rational. What is Known: • In children, eosinophilia is common, and mild eosinophilia occurs frequently. • Malignancies presents frequently with severe eosinophilia. What is New: • Primary immunodeficiencies were not a rare cause of eosinophilia, especially in countries such as the Middle East and eastern Mediterranean countries, where the countries consanguineous marriages are common, and should be investigated in children with eosinophilia who do not have allergic or infectious diseases. • In literature, there are many algorithms about childhood hypereosinophilia. However, mild eosinophilia is extremely important in children. Because all patients with malignancy and most of the patients with rheumatic diseases presented with mild eosinophilia. Therefore, we proposed an algorithm for childhood eosinophilia that includes mild eosinophilia besides moderate and severe cases.

Abstract
Background There are gaps in our understanding of the epidemiology of atopic dermatitis (AD) in adults. Objective To evaluate the prevalence and severity of AD in adults from countries/regions within Asia, Eurasia, Latin America, Middle East, and Russia. Methods This international, web-based survey was performed in Argentina, Brazil, China, Colombia, Egypt, Hong Kong, Israel, Malaysia, Mexico, Russia, Kingdom of Saudi Arabia (KSA), Singapore, Taiwan, Thailand, Turkey, and United Arab Emirates. Questionnaires were sent to adult members of online respondent panels for determination of AD and assessment of severity. A diagnosis of AD required respondents to meet the modified United Kingdom (UK) Working Party criteria and to self-report they had a physician diagnosis of AD. Severity of AD was determined using Patient-Oriented Scoring of Atopic Dermatitis (PO-SCORAD), Patient-Oriented Eczema Measure (POEM), and Patient Global Assessment (PGA). Results Among respondents by country/region the prevalence of AD ranged from 3.4% in Israel to 33.7% in Thailand. The prevalence was generally higher in females versus males. Severity varied by scale, although regardless of scale the proportion of respondents with mild and moderate disease was higher than severe disease. PGA consistently resulted in the lowest proportion of severe AD (range 2.4% China - 10.8% Turkey) relative to PO-SCORAD (range 13.4% China - 41.6% KSA) and POEM (range 5.1% China - 16.6% Israel). Conclusions This survey highlights the importance of AD in adults, with high prevalence and high morbidity among respondents and emphasizes that AD is not just a disease of childhood-there is disease persistence and chronicity in adults.

Abstract
Cow's milk allergy (CMA) is the most prevalent food allergy (FA) in infancy and early childhood and can be present with various clinical phenotypes. The significant increase in FA rates recorded in recent decades has been associated with environmental and lifestyle changes that limit microbial exposure in early life and induce changes in gut microbiome composition. Gut microbiome is a diverse community of microbes that colonize the gastrointestinal tract (GIT) and perform beneficial functions for the host. This complex ecosystem interacts with the immune system and has a pivotal role in the development of oral tolerance to food antigens. Emerging evidence indicates that alterations of the gut microbiome (dysbiosis) in early life cause immune dysregulation and render the host susceptible to immune-mediated diseases later in life. Therefore, the colonization of the gut by "healthy" microbes that occurs in the first years of life determines the lifelong health of the host. Here, we present current data on the possible role of the gut microbiome in the development of CMA. Furthermore, we discuss how gut microbiome modification might be a potential strategy for CMA prevention and treatment.

Abstract
Atopic dermatitis is a chronic relapsing dermatopathology involving IgE against allergenic materials present on mammalian epithelial surfaces. Allergens are as diverse as pet danders, and polypeptides expressed by microbes of the mammalian microbiome, e.g., Malassezia spp. The Acari Hypothesis posits that the mammalian innate immune system utilizes pathogen-bound acarian immune effectors to protect against the vectorial threat posed by mites and ticks. Per The Hypothesis, IgE-mediated allergic disease is a specious consequence of the pairing of acarian gastrointestinal materials, e.g., allergenic foodstuffs, with acarian innate immune effectors that have interspecies operability. In keeping with The Hypothesis, the IgE profile of atopic patients should include both anti-acarian antibodies and specious antibodies responsible for specific allergy. Further, the profile should inform on the diet and/or environment of the acarian vector. In this regard, the prevalence of Demodex and Dermatophagoides on the skin of persons suffering from atopic dermatitis is increased. Importantly, the diets of these mites correspond well with the allergens of affected patients. In this report, roles for these specific acarians in the pathogenesis of atopic dermatitis are proposed and elaborated.

Abstract
Background: In France, updated data on food allergies (FAs) are lacking, despite the need for efficient FA management and prevention. This study aimed to evaluate the prevalence of FAs in children in France, describe the most common allergens and determine the prevalence of atopic diseases in children with FAs. Methods: The ELFE study comprises a French nationwide birth cohort, including 18,329 children born in 2011. FAs were assessed by parental reports of food avoidance based on medical advice related to FAs, provided at 2 months and 2, 3.5 and 5.5 years of age. Data regarding FAs were available for 16,400 children. Data were weighted to account for selection and attrition bias. Results: From birth to 5.5 years of age, FAs were reported for 5.94% (95% CI: 5.54–6.34) children. Milk was the most common allergen, followed by egg, peanut, exotic fruits, tree nuts, gluten and fish. Among children with FAs, 20.5% had an allergy to at least two different groups of allergens; 71% reported eczema at least once before 5.5 years of age; 24.4% reported incidence of asthma; and 42.3% reported incidence of allergic rhinitis or conjunctivitis. Conclusion: In France, the prevalence of FAs in children up to 5.5 years of age is approximately 6%. It was demonstrated that 1 in 5 children with allergies had multiple FAs.

Atopic Dermatitis and Food Allergy: A Complex Interplay What We Know and What We Would Like to Learn. J Clin Med 2022; 11:jcm11144232. [PMID: 35887996 PMCID: PMC9317394 DOI: 10.3390/jcm11144232] [Citation(s) in RCA: 16] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/03/2022] [Revised: 07/06/2022] [Accepted: 07/19/2022] [Indexed: 12/07/2022] Open
Abstract
Atopic dermatitis (AD) is a chronic inflammatory skin disorder characterized by intense pruritus, eczematous lesions, and relapsing course. It presents with great clinical heterogeneity, while underlying pathogenetic mechanisms involve a complex interplay between a dysfunctional skin barrier, immune dysregulation, microbiome dysbiosis, genetic and environmental factors. All these interactions are shaping the landscape of AD endotypes and phenotypes. In the “era of allergy epidemic”, the role of food allergy (FA) in the prevention and management of AD is a recently explored “era”. Increasing evidence supports that AD predisposes to FA and not vice versa, while food allergens are presumed as one of the triggers of AD exacerbations. AD management should focus on skin care combined with topical and/or systemic treatments; however, in the presence of suspected food allergy, a thorough allergy evaluation should be performed. Food-elimination diets in food-allergic cases may have a beneficial effect on AD morbidity; however, prolonged, unnecessary diets are highly discouraged since they can lead to loss of tolerance and potentially increase the risk of IgE-mediated food allergy. Preventive AD strategies with the use of topical emollients and anti-inflammatory agents as well as early introduction of food allergens in high-risk infants seem promising in managing and preventing food allergy in AD patients. The current review aims to overview data on the complex AD/FA relationship and provide the most recent developments on whether food allergy interventions change the AD course and vice versa.

Abstract
Atopic dermatitis is a chronic as well as widespread skin disease which has significant influence on the life attributes of affected people and their families. Systemic immunosuppressive drugs can be utilised for effective care of disease, although they are often prescribed for rigorous disruption or disease that is complicated to manage. Therefore, topical applications of corticosteroids are considered the primary pharmacologic therapies for atopic dermatitis, and research recommends that these medications might be helpful in preventing disease flare-ups. However, topical medicine administration to deeper layers of skin is challenging because of the skin anatomic barrier that restricts deeper drug permeation, and also due to barrier function abnormalities in atopic dermatitis skin, which might result in systemic drug absorption, provoking systemic consequences. Hence, effective management of atopic dermatitis needs new, effective, safe and targeted treatments. Therefore, nanotechnology-based topical therapeutics have attracted much interest nowadays because of their tendency to increase drug diffusion and bioavailability along with enormous drug targeting potential to affected cells, and, thereby, reducing the adverse effects of medications. In this review, we mention different symptoms of atopic dermatitis, and provide an overview of the different triggering factors causing atopic dermatitis, with emphasis on its epidemiology, pathophysiology, clinical features and diagnostic, and preventive measures. This review discusses existing therapeutics for treating atopic dermatitis, and the newer approaches as well as the current classical pharmacotherapy of atopic dermatitis against new nanoparticle skin delivery systems. This review has also briefly summarised the recent patents and clinical status of therapeutic modalities for atopic dermatitis.

Abstract
Allergists are often asked to evaluate children with atopic dermatitis (AD) for allergen triggers to disease. Testing, particularly for food triggers, often leads to elimination diets in an effort to improve AD control. However, the dual exposure hypothesis suggests that oral tolerance to food antigens is promoted through high-dose oral exposure, where sensitization occurs through lower dose cutaneous exposure. This suggests that strict elimination diets may pose some risks in children with AD. In addition, emerging evidence suggests an important role of skin inflammation in further allergic disease and the importance of dietary exposure to maintain oral tolerance. This work group report reviews current guidelines-based management for children with moderate-to-severe AD, the evidence for current recommendations for the evaluation and management of these children, provides a nuanced examination of these studies, and addresses current knowledge gaps in the care of these children.

Early Introduction of Multi-Allergen Mixture for Prevention of Food Allergy: Pilot Study. Nutrients 2022; 14:nu14040737. [PMID: 35215387 PMCID: PMC8879339 DOI: 10.3390/nu14040737] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/26/2022] [Revised: 02/03/2022] [Accepted: 02/04/2022] [Indexed: 01/09/2023] Open
Abstract
The incidence and prevalence of food allergy (FA) is increasing. While several studies have established the safety and efficacy of early introduction of single allergens in infants for the prevention of FA, the exact dose, frequency, and number of allergens that can be safely introduced to infants, particularly in those at high or low risk of atopy, are still unclear. This 1-year pilot study evaluated the safety of the early introduction of single foods (milk, egg, or peanut) vs. two foods (milk/egg, egg/peanut, milk/peanut) vs. multiple foods (milk/egg/peanut/cashew/almond/shrimp/walnut/wheat/salmon/hazelnut at low, medium, or high doses) vs. no early introduction in 180 infants between 4-6 months of age. At the end of the study, they were evaluated for plasma biomarkers associated with food reactivity via standardized blood tests. Two to four years after the start of the study, participants were evaluated by standardized food challenges. The serving sizes for the single, double, and low dose mixtures were 300 mg total protein per day. The serving sizes for the medium and high dose mixtures were 900 mg and 3000 mg total protein, respectively. Equal parts of each protein were used for double or mixture foods. All infants were breastfed until at least six months of age. The results demonstrate that infants at either high or low risk for atopy were able to tolerate the early introduction of multiple allergenic foods with no increases in any safety issues, including eczema, FA, or food protein induced enterocolitis. The mixtures of foods at either low, medium, or high doses demonstrated trends for improvement in food challenge reactivity and plasma biomarkers compared to single and double food introductions. The results of this study suggest that the early introduction of foods, particularly simultaneous mixtures of many allergenic foods, may be safe and efficacious for preventing FA and can occur safely. These results need to be confirmed by larger randomized controlled studies.

Abstract
BACKGROUND Guidelines for management of patients with allergic conditions are available, but the added value of nurses, allied healthcare professionals (AHPs), and general practitioners (GPs), in the management of allergic disease, has not been fully clarified. The European Academy of Allergy and Clinical Immunology (EAACI) appointed a task force to explore this issue. AIM To investigate the added value of nurses, AHPs, and GPs in management of allergic diseases, in an integrated model of care. METHODS A search was made of peer-reviewed literature published between 2010 and December 2020 (Cochrane Library, PubMed, and CINAHL) on the involvement of the various specific healthcare providers (HCPs) in the management of allergic diseases. RESULTS Facilitative models of care for patients with allergies can be achieved if HCP collaborates in the diagnosis and management. Working in multi-disciplinary teams (MDT) can increase patients' understanding of the disease, adherence to treatment, self-care capabilities, and ultimately improve quality of life. The MDT competencies and procedures can be improved and enhanced in a climate of mutual respect and shared values, and with inclusion of patients in the planning of care. Patient-centered communication among HCPs and emphasis on the added value of each profession can create an effective integrated model of care for patients with allergic diseases. CONCLUSION Nurses, AHPs, and GPs, both individually and in collaboration, can contribute to the improvement of the management of patients with allergic disease. The interaction between the HCPs and the patients themselves can ensure maximum support for people with allergies.

Abstract
Internists are front-line health care providers that commonly provide the first encounter to patients for dermatological conditions, especially atopic dermatitis (AD). Internists need to be comfortable with managing mild-moderate AD in their practices. Criteria and guidelines established in dermatology literature are available to help the general practitioner diagnose and treat AD. AD is a systemic disease associated with multiple cutaneous and extra-cutaneous comorbidities that warrant screening by internists, especially mental health conditions. Environmental factors may play a role in the development or worsening of AD; however, there is currently no strong evidence to guide specific population- or clinic-based interventions for their avoidance. While food allergies are common in AD patients, the role of food allergens as an exacerbating factor for AD is controversial. Before starting any dietary modifications, careful evaluation should be performed by an allergist. If the patient is not well-controlled despite adequate topical therapies or is experiencing severe/worsening disease, early referral to dermatology is warranted to rule out confounding diagnoses and/or escalation to systemic therapies. Finally, it is important to recognise the racial disparities present in AD and address these when formulating treatment plans.Key messages:Confounding dermatoses, either instead of or in addition to AD, should be considered in treatment-refractory AD, and the appropriate workup may be initiated while awaiting dermatology referral.AD patients have multiple cutaneous and extra-cutaneous comorbidities that warrant screening by internists, especially mental health conditions.

Abstract
Atopic dermatitis, a common chronic and pruritic inflammatory skin disorder, can create significant disruptions in sleep and quality of life. Atopic dermatitis is especially common in infants and children; therefore, safe and natural therapeutic options have considerable appeal. Over the past several decades, there has been an increase in the prevalence of atopic dermatitis in industrialized nations. Also, there is variability in the prevalence of atopic dermatitis in the United States, both across and within states. Environmental factors including diet are believed to be associated with this increased risk. Dietary interventions continue to be an area of keen interest and have been studied extensively, albeit with variable results. Maternal dietary restrictions during pregnancy and lactation, hydrolyzed or partially hydrolyzed formulas, delaying the introduction of solid foods, and omega-3 or omega-6 fatty acids supplementation do not appear to have a beneficial effect on the treatment and prevention of atopic dermatitis. Exclusive breastfeeding for 3 to 4 months, a diet high in fruits and vegetables, and prebiotics might have a beneficial effect. Because environmental triggers, including dietary exposures, are thought to play a role in the pathogenesis of atopic dermatitis, we herein review the current literature on the role of dietary habits, vitamin and mineral supplementation, and probiotics on the treatment and prevention of atopic dermatitis.

Abstract
Atopic dermatitis (AD) is the leading chronic skin inflammatory disease and the initial manifestation of atopic march. Available evidence supports the notion that primary prevention early in life leads to a decreased incidence of AD, thus possibly decreasing the subsequent occurrence of atopic march. Nutritional status is essential to a proper functioning immune system and is valued for its important role in AD. Essential nutrients, which include carbohydrates, proteins, lipids, vitamins, and minerals, are transferred from the mother to the fetus through the placenta during gestation. Various nutrients, such as polyunsaturated fatty acids (PUFAs) and vitamin D, were studied in relation to maternal status and offspring allergy. However, no strong evidence indicates that a single nutrient or food in mothers' diet significantly affects the risk of childhood AD. In the light of current evidence, mothers should not either increase nor avoid consuming these nutrients to prevent or ameliorate allergic diseases in their offspring. Each essential nutrient has an important role in fetal development, and current government recommendations suggest specific intake amounts for pregnant women. This review discusses evidence on how various nutrients, including lipids (monounsaturated fatty acids, PUFAs, saturated fatty acids, and short-chain fatty acids), carbohydrates (oligosaccharides and polysaccharides), proteins, vitamins (A, B, C, D, and E), and trace minerals (magnesium, iron, zinc, copper, selenium, and strontium) in maternal status are associated with the development of AD and their possible mechanisms.

Abstract
Zea mays L. (Poaceae), also known as purple corn, is an annual herbaceous plant that is grown as food for human consumption in a variety of forms, including cooking oils and sweeteners in processed food and beverage products. The purpose of this study was to determine whether a novel purple corn extract, FB801, might have an anti-atopic dermatitis (AD) effect on AD-like skin lesions induced by 2,4-dinitrochlorobenzene (DNCB) in BALB/c mice. Topical sensitization (1%) and challenge (0.3%) by DNCB were performed on the dorsal skin and right ear of BALB/c mice to induce AD. Following FB801 and dexamethasone administered orally, the severity of skin lesions was examined macroscopically and histologically. Serum levels of immunoglobulin E (IgE) and various cytokines were determined by enzyme-linked immunosorbent assay. Oral administration of FB801 significantly reduced typical symptoms of AD (erythema/bleeding, swelling, molting/erosion and scaling/drying), scratching frequencies, and the recruitment of inflammatory and mast cells. In addition, FB801 suppressed serum levels of IgE and T helper (Th)2 type cytokines such as interleukin (IL)-4 and IL-10 in DNCB-treated BALB/c mice. Furthermore, FB801 reduced the degradation of inhibitor of nuclear factor-κB proteins (NF-κB) in tumor necrosis factor (TNF)-α-stimulated human keratinocyte (HaCaT) cells. These results suggest that FB801 inhibited the development of the AD-like skin symptoms by regulating Th1 and Th2 responses in the skin lesions in mice and suppressing TNF-α induced NF-κB activation in HaCaT cells, suggesting that FB801 has potential application as an effective alternative therapy for the prevention and management of AD.

Abstract
Atopic dermatitis is a chronic inflammatory disease that can arise during the first months of life or at maturity and have a significant negative impact on the quality of life. The main pathogenic mechanism is the breakdown of cutaneous barrier integrity, which is associated with systemic inflammatory immunologic disorders. Atopic dermatitis involves numerous immunologic, allergic, respiratory, and ophthalmologic comorbidities that develop through similar intricate pathogenic phenomena. The atopic march represents the evolution in time of various allergic diseases, of which food allergies often cause the first manifestations of atopy, even from a very young age. Chronic inflammation translated through specific markers, next to increased immunoglobulin E (IgE) serum levels and heterogenous clinical manifestations, argue for the inclusion of atopic dermatitis in the systemic disease category.

Abstract
Food allergy evaluation for dermatologic disorders is warranted when Type 1 allergy is suspected, and includes skin prick testing (SPT) or measurement of specific immunoglobulin E (IgE) levels. The utility of these tests for identifying triggers is improved with clinical correlation, especially for contact urticaria, and protein contact dermatitis, which are mixed mechanism diseases. In atopic dermatitis (AD), patients are at risk for development of food allergy, and screening with SPT or IgE may be considered in severe AD, especially to guide early food introduction. Management of food-related AD exacerbations should focus on modifications in skincare before evaluating for allergy.

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

Abstract
Background Increased allergy frequency may have a significant impact on the skin, one of the largest targeted organs for allergic and immunological responses. Methods An online survey of 2036 adults as a representative sample of the French general population was conducted to evaluate the prevalence of self-reported allergies, the populations who report allergies and the skin conditions related to allergies. Results In general, 20.2% of French adults (average age 45 ± 15.8 years) reported allergies. These allergies were respiratory allergies (55.3%), skin allergies (48.8%) and food allergies (27.9%), and 78.9% indicated that their reported allergies were diagnosed by a doctor. In addition, 53.2% of individuals reporting an allergy also indicated that they experienced associated skin reactions. In comparison to those who did not report an allergy, these individuals were 1.5 to 4 times more likely to have a skin disease and 3 times more likely to have sensitive skin or skin reactions when using skincare products. Conclusion It is estimated that over 10 million French adults have allergies. These data will help increase awareness among the allergic population and healthcare professionals about the burden associated with allergies and the need for management to reduce their health impact.

Abstract
Significance: Cutaneous wounds are a major problem in both human and equine medicine. The economic cost of treating skin wounds and related complications in humans and horses is high, and in both species, particular types of chronic wounds do not respond well to current therapies, leading to suffering and morbidity. Recent Advances: Conventional methods for the treatment of cutaneous wounds are generic and have not changed significantly in decades. However, as more is learned about the mechanisms involved in normal skin wound healing, and how failure of these processes leads to chronic nonhealing wounds, novel therapies targeting the specific pathologies of hard-to-heal wounds are being developed and evaluated. Critical Issues: Physiologically relevant animal models are needed to (1) study the mechanisms involved in normal and impaired skin wound healing and (2) test newly developed therapies. Future Directions: Similarities in normal wound healing in humans and horses, and the natural development of distinct types of hard-to-heal chronic wounds in both species, make the horse a physiologically relevant model for the study of mechanisms involved in wound repair. Horses are also well-suited models to test novel therapies. In addition, studies in horses have the potential to benefit veterinary, as well as human medicine.

Abstract
Background: Food allergies are common, affecting 1 in 13 school children in the United States and their prevalence is increasing. Many misconceptions exist with regards to food allergy prevention, diagnosis and management. Objective: The main objective of this review is to address misconceptions with regards to food allergies and discuss the optimal, evidence-based approach for patients who carry this diagnosis. Observations: Common misconceptions in terms of food allergy prevention include beliefs that breastfeeding and delayed introduction of allergenic foods prevent the development of food allergies. In terms of diagnosis, statements such as ‘larger skin prick tests or/and higher levels of food-specific IgE can predict the severity of food-induced allergic reactions’, or ‘Tryptase is always elevated in food-induced anaphylaxis’ are inaccurate. Additionally, egg allergy is not a contraindication for receiving the influenza vaccine, food-allergy related fatalities are rare and peanut oral immunotherapy, despite reported benefits, is not a cure for food allergies. Finally, not all infants with eczema will develop food allergies and epinephrine auto-injectors may unfortunately be both unavailable and underused in food-triggered anaphylaxis. Conclusions and relevance: Healthcare professionals must be familiar with recent evidence in the food allergy field and avoid common misunderstandings that may negatively affect prevention, diagnosis and management of this chronic disease.

Abstract
Atopic dermatitis (AD) is a common presenting complaint by children and their caretakers to their primary care providers. On testing, children with AD frequently exhibit positive food-specific IgE levels in the absence of immediate allergic reactions. Misinterpretation of these false positive tests can lead to unnecessary food avoidance, which can have tremendous psychosocial, economic and nutritional consequences and, in some cases, facilitate the development of an immediate hypersensitivity to the food. We present a child with persistent AD who underwent broad testing that led to unnecessary food avoidance resulting in Vitamin D deficiency, growth failure and the development of an IgE-mediated food allergy. This case underscores the need for caution by primary care clinicians in using food avoidance diets as a treatment for AD and the importance of limiting allergy testing to foods only when the clinical history indicates an immediate hypersensitivity reaction.

Abstract
Food allergies are the result of immune responses that cause adverse reactions to foods. Immune responses to foods may produce a spectrum of symptoms and disorders, including acute allergic reactions and anaphylaxis, food protein-induced allergic proctocolitis, food protein-induced enterocolitis syndrome, food-dependent, exercise-induced anaphylaxis, and oral allergy syndrome (pollen-food allergy syndrome). Food-allergic responses also contribute to chronic inflammatory disorders such as eosinophilic esophagitis and atopic dermatitis. Although food allergy affects people from infancy through adulthood, there are allergic features that differ according to age (ie, presentation, triggers, and natural course) and have important implications for diagnosis, prognosis, and management. New food allergies can develop at any age, and we propose similarities in the etiology of de novo food allergy whether in infancy or adulthood. The approach to managing food allergy changes dramatically over the life course, and physicians and patients must respond accordingly to optimize care. Food allergy therapies are emerging, and the efficacy and safety of these interventions could differ by age group of those treated. In this review, we highlight interesting observations on the etiology and characteristics of food allergy presenting at different ages and discuss clinical management as it relates to life stage.

Abstract
Oral food challenges are an integral part of an allergist's practice and are used to evaluate the presence or absence of allergic reactivity to foods. A work group within the Adverse Reactions to Foods Committee of the American Academy of Allergy, Asthma & Immunology was formed to update a previously published oral food challenge report. The intention of this document was to supplement the previous publication with additional focus on safety, treatment of IgE-mediated allergic reactions, guidance for challenges in infants and adults, psychosocial considerations for children and families participating in an oral food challenge, specific guidance for baked milk or baked egg challenges, masking agents and validated blinding recipes for common food allergens, and recommendations for conducting and interpreting challenges in patients with suspected food protein-induced enterocolitis syndrome. Tables and figures within the report and an extensive online appendix detail age-specific portion sizes, appropriate timing for antihistamine discontinuation, serum and skin test result interpretation, written consents, and instructional handouts that may be used in clinical practice.

Abstract
Adverse food reactions include immune-mediated food allergies and non-immune-mediated intolerances. However, this distinction and the involvement of different pathogenetic mechanisms are often confused. Furthermore, there is a discrepancy between the perceived vs. actual prevalence of immune-mediated food allergies and non-immune reactions to food that are extremely common. The risk of an inappropriate approach to their correct identification can lead to inappropriate diets with severe nutritional deficiencies. This narrative review provides an outline of the pathophysiologic and clinical features of immune and non-immune adverse reactions to food-along with general diagnostic and therapeutic strategies. Special emphasis is placed on specific nutritional concerns for each of these conditions from the combined point of view of gastroenterology and immunology, in an attempt to offer a useful tool to practicing physicians in discriminating these diverging disease entities and planning their correct management. We conclude that a correct diagnostic approach and dietary control of both immune- and non-immune-mediated food-induced diseases might minimize the nutritional gaps in these patients, thus helping to improve their quality of life and reduce the economic costs of their management.

Abstract
Probiotics seem to have promising effects in the prevention and treatment of allergic conditions including atopic dermatitis (AD) and food allergy. The purpose of this multicenter randomized placebo-controlled trial was to evaluate the effectiveness of a probiotic preparation comprising Lactobacillus rhamnosus ŁOCK 0900, Lactobacillus rhamnosus ŁOCK 0908, and Lactobacillus casei ŁOCK 0918 in children under 2 years of age with AD and a cow’s milk protein (CMP) allergy. The study enrolled 151 children, who—apart from being treated with a CMP elimination diet—were randomized to receive the probiotic preparation at a daily dose of 109 bacteria or a placebo for three months, with a subsequent nine-month follow-up. The primary outcomes included changes in AD symptom severity assessed with the scoring AD (SCORAD) index and in the proportion of children with symptom improvement (a SCORAD score decreased by at least 30% in comparison with that at baseline). After the three-month intervention, both the probiotic and placebo groups showed a significant (p < 0.0001) decrease in SCORAD scores, which was maintained nine months later. The percentage of children who showed improvement was significantly higher in the probiotic than in the placebo group (odds ratio (OR) 2.56; 95% confidence interval (CI) 1.13–5.8; p = 0.012) after three months. Probiotics induced SCORAD improvement mainly in allergen sensitized patients (OR 6.03; 95% CI 1.85–19.67, p = 0.001), but this positive effect was not observed after nine months. The results showed that the mixture of probiotic ŁOCK strains offers benefits for children with AD and CMP allergy. Further research is necessary to assess the effect of probiotic supplementation on the development of immune tolerance (NCT04738565).

Abstract
Atopic dermatitis and food allergy are the most common allergic conditions affecting the infant population. Both immunoglobulin E (IgE)-mediated and non-IgE-mediated food allergy are seen in infancy. Early life feeding guidelines have changed dramatically over the past 30 years, more recently because of an improved understanding of IgE-mediated food allergy. This article focuses on identification, diagnosis, management, and prevention of food allergy in the infant population.

Abstract
Background Atopic diseases, such as atopic dermatitis (AD) and food allergy (FA), have increased in prevalence in industrialized countries during the past few decades and pose a significant health burden. They appear to have a common underlying mechanism and a natural disease progression. AD is generally the first atopic disease to manifest followed by other atopic diseases, such as FA, allergic rhinitis, or allergic asthma suggesting that they are likely different manifestations of the same disease. Body Evidence suggests that allergic sensitization occurs through an impaired skin barrier, while consumption of these foods at an early age may actually result in tolerance. This has been termed the Dual-Allergen-Exposure hypothesis. Loss of barrier integrity has been hypothesized to enable penetration of allergens, pollutants, and microbes and initiation of an inflammatory immune cascade of events leading to sensitization. The immune dysfunction is thought to further exacerbate the impaired skin barrier to form a vicious cycle. There is much interest in preventing or protecting the skin barrier from developing a proinflammatory atopic state, which may potentially lead to the development of AD and subsequently, FA. Conclusion Research on preventing or treating skin barrier dysfunction is ongoing. A number of studies have evaluated the efficacy of emollients in preventing AD and FA with mixed results. Studies have differed in the study design, population characteristics, emollients type, and frequency, duration, and area of application. Emollient type has varied widely from oils, creams, petrolatum-based lotions, and trilipid creams. Current research is directed towards the use of trilipid emollients that are similar to the skin’s natural lipid composition with a 3:1:1 ratio of ceramides, cholesterol and free fatty acids and a pH that is similar to that of skin to determine their effectiveness for skin barrier repair and prevention of AD and FA.

Abstract
BACKGROUND The relationship between atopic dermatitis (AD) and abnormal bone metabolism remains unclear. We performed a systematic review and meta-analysis to determine whether patients with AD were associated with increased risks of low bone mineral density (BMD), osteopenia, osteoporosis, and related fractures. METHODS We searched PubMed, Embase, and the Cochrane Library through December 2019 to identify studies that investigated the association between AD and abnormal bone metabolism (including BMD, osteopenia, osteoporosis, and related fractures). The predefined primary outcome was related fractures; secondary outcomes included osteoporosis, osteopenia, and BMD. We calculated the summary odds ratios (ORs) and 95% confidence intervals (CIs) using a random-effects model. RESULTS Ten studies were included in this systematic review. In children and adolescents, four studies investigated the association between AD and BMD; three studies indicated that children and adolescents with AD were associated with an increased risk of low BMD; one study found similar BMD between AD and control groups. In adults, three studies assessed the risk of fracture and were included in the meta-analysis, comprising 562,405 AD patients among 3,171,268 participants. Adults with AD were associated with an increased risk of fracture (OR 1.13; 95% CI, 1.05-1.22; P=0.001). Three studies investigated the association between AD and osteoporosis, which suggested that patients with AD were associated with an increased risk of osteoporosis (OR 1.95; 95% CI, 1.18-3.23; P=0.009). Further, patients with AD were associated with increased risks of osteopenia (OR 1.90; 95% CI, 1.51-2.38; P<0.001) and low BMD at the femur and spine. CONCLUSIONS Patients with AD were associated with increased risks of low BMD, osteopenia, osteoporosis, and related fractures. Both clinical studies and basic research are needed to clarify the mechanisms of association between AD and abnormal bone metabolism.

Abstract
Background: It is widely acknowledged that food sensitization is related to atopic dermatitis in infants and young children. Objective: To investigate the association of aeroallergen sensitization with increased rates and severity of atopic dermatitis in school children. Methods: We enrolled 576 children (mean age, 9.4 ± 1.8 years) from six elementary schools. Atopic dermatitis was diagnosed by questionnaires, and severity was rated by physical examinations graded by using the Scoring Atopic Dermatitis (SCORAD) index. Skin-prick tests to 22 common allergens (6 aeroallergens and 16 food allergens) were conducted. Logistic and linear regression analyses were performed by using two models: model I adjusted for age, sex, and body mass index z score; and model II adjusted for all model I factors plus asthma and allergic rhinitis. Results: We diagnosed atopic dermatitis in 22.4% (n = 129) of the children, sensitization to foods in 48.3% (n = 278), and sensitization to aeroallergens in 11.3% (n = 65). A total of 26.2% of the children (n = 149) had mild and 6.5% had moderate-to-severe symptoms and signs of atopic dermatitis (n = 37). Atopic dermatitis was associated with sensitization to aeroallergens and eosinophilia (model I), but this risk was no longer significant after additional adjustment for current allergic status (model II). However, the relationship of the total SCORAD score with aeroallergen sensitization and eosinophilia was significant in model I and model II. Conclusion: The severity of atopic dermatitis correlated with the extent of allergic sensitization and eosinophilia. Analysis of our results suggests that more sensitization to dust mites and eosinophilia are related to increased rates and high severity scores of atopic dermatitis.

Abstract
Introduction: The rising prevalence of allergies can substantially impact the skin, which is one of the largest targets for allergic and immunologic responses. We present the results of an online survey assessing self-reported allergy prevalence in Russians, outline the populations who report allergies and characterize the skin conditions associated with allergy. Methods: An online survey was conducted in Russia of 2010 adults as a representative sample of the general Russian population. Results: A total of 34.9% of Russian adults (mean age: 41.3 ± 14.4 years old) reported having allergies. Reported allergies included skin allergies (73.3%), food allergies (53.9%) and respiratory allergies (43.4%), and 65.9% reported their allergies had been diagnosed by a doctor. In total, 75.1% of those who reported allergies also reported experiencing associated skin reactions, they were 1.5–5.5 times more likely to report a cutaneous disease and were 1.5 times to report sensitive skin compared to those who did not report allergies. In addition, those that reported allergies were also 2 times more likely to report experiencing skin reactions when using skincare products. Conclusion: It is estimated that over 35 million Russian adults have allergies. These results will help raise awareness about the burden of allergies and the need to develop solutions to mitigate their impact on health.

Abstract
Atopic dermatitis is a chronic allergic disease with multifactorial causation. Although its association with diet has been demonstrated, it remains unclear whether the prevalence of atopic dermatitis among adults is associated with nutrition label awareness. Nutrition label awareness indicates knowledge of the existence of nutrition labels on processed food, and the use of them for food selection. In this cross-sectional study, we analyzed the relationship between nutrition label awareness and the prevalence of atopic dermatitis among men and women using data from the Korean National Health and Nutrition Examination Survey VI (2013–2015), including a nationally representative sample of 13,505 Korean adults (aged > 19 years). The relationship between the prevalence of atopic dermatitis and nutrition label awareness was evaluated using t-tests, χ2 tests and multivariate adjusted logistic regression analysis. Although univariate analysis showed that atopic dermatitis was associated with nutrition label awareness in both men and women, after adjustment for covariates, there was no significant association among men. The significant association between the prevalence of atopic dermatitis and nutrition label awareness among women reveals a sex-based difference in this relationship in adults, and atopic dermatitis may be managed and prevented among women by targeted education regarding nutrition labels and diet.

Abstract
PURPOSE Specific food consumption, besides food allergy, may aggravate atopic dermatitis (AD). However, previous reports on the association between AD and food intake in adolescents are scarce. The aim of this study was to determine the relationship between AD and specific food consumption frequency in adolescents. METHODS A cross-sectional analysis using data from the Korea Youth Risk Behavior Web-based Survey 2017 was performed. The frequency of food consumption in the recent-diagnosed AD group (AD diagnosed within 12 months) compared to those in the previous-diagnosed AD (AD diagnosed more than 12 months ago) or control group were investigated. RESULTS A total of 53,373 participants were eligible for this study. The weighted prevalence of the recent-diagnosed AD and the previous-diagnosed AD was 7.39% and 18.00%, respectively. When compared with subjects with the previous-diagnosed AD, those with the recent-diagnosed AD were significantly more likely to frequently consume fast foods (odds ratio OR 1.405; 95% CI 1.150-1.717), energy drinks (OR 1.457; 95% CI 1.175-1.807), or convenience food (OR 1.304; 95% CI 1.138-1.495). Patients of the recent-diagnosed AD were significantly more likely to frequently consume fast foods (OR 1.374; 95% CI 1.155-1.634) than the control group. The differences in the frequency of specific food consumption among groups were more pronounced in high school students than in middle school students. CONCLUSIONS Frequent intake of fast foods, energy drinks, and convenience food was related to the recent-diagnosed AD in adolescents. Prospective cohort and interventional studies are needed to identify causal relationships.

Are the most common food allergens in an Iranian atopic population compatible with worldwide reports? A systemic review and meta-analysis with molecular classification of frequent allergens. Allergol Immunopathol (Madr) 2019; 47:604-618. [PMID: 31353064 DOI: 10.1016/j.aller.2019.04.005] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/05/2018] [Revised: 04/20/2019] [Accepted: 04/29/2019] [Indexed: 01/17/2023]
Abstract
BACKGROUND Undesirable immunological responses to alimentary allergens are one of the hallmarks of atopic diseases. The prevalence of common food allergens is dissimilar among different communities with distinct nutritional habits and genetic characteristics. AIM To assess the prevalence of the most common food allergens in Iran, using different reliable studies. METHODS All studies determining sensitization to common food allergens that were indexed in PubMed, Web of Science, Google Scholar, ProQuest, Scopus, Iran Medex, and Magiran were included in this review. To perform a meta-analysis, STATA 14 and metaprop command was applied. A logistic-normal random-effects model with Freeman-Tukey double arcsin transformation was applied to combine the findings of different studies and evaluate their heterogeneity. Random pooled estimate (ES) (pooled prevalence), 95% confidence interval (95% CI) and p-value were determined. RESULTS A total of 23 studies with data from a total of 6126 children and adults met the inclusion criteria for entering this meta-analysis. The respective pooled prevalence of a positive family history of allergy and positive specific IgE to at least one food allergen was 72% (95% CI: 66-77%) and 41% (95% CI: 33-49%), respectively. Our results in the total population revealed that allergic sensitization to egg yolk, cow's milk (CM), egg white, and wheat were 25% (95% CI: 16%-35%), 24% (95% CI: 19-29%), 23% (95% CI: 18%-28%), and 9% (95% CI: 6%-14%), respectively. Walnut, peanut, and soybean sensitization was detected in 23% (95% CI: 17%-31%), 23% (95% CI: 13%-33%), and 20% (95% CI: 12%-28%) of patients, respectively. Random pooled ES for sensitization to shrimp and fish was 32% (95% CI: 21-45%) and 12% (95% CI: 6-20%), respectively. The result of analysis in different age groups revealed that allergic sensitization to milk, egg white, and egg yolk declines in higher age groups; while shrimp sensitization increases in older patients. In patients with atopic dermatitis, egg white was the most frequent food allergen 29% (95% CI = 18-42%); while wheat was the least frequent 8% (95% CI = 4-14%). CONCLUSIONS Considering the prevalence of different food allergens, the results of the current meta-analysis revealed that egg yolk and cow's milk had the second and third rate after shrimp, respectively. The high prevalence of sensitization to shrimp may be attributed to its high consumption in coastal areas and/or cross-reactivity of shrimp with some aeroallergens such as mites.

Abstract
BACKGROUND Smartphone diet-tracking apps may help individuals lose weight, manage chronic conditions, and understand dietary patterns; however, the usabilities and functionalities of these apps have not been well studied. OBJECTIVE The aim of this study was to review the usability of current iPhone operating system (iOS) and Android diet-tracking apps, the degree to which app features align with behavior change constructs, and to assess variations between apps in nutrient coding. METHODS The top 7 diet-tracking apps were identified from the iOS iTunes and Android Play online stores, downloaded and used over a 2-week period. Each app was independently scored by researchers using the System Usability Scale (SUS), and features were compared with the domains in an integrated behavior change theory framework: the Theoretical Domains Framework. An estimated 3-day food diary was completed using each app, and food items were entered into the United States Department of Agriculture (USDA) Food Composition Databases to evaluate their differences in nutrient data against the USDA reference. RESULTS Of the apps that were reviewed, LifeSum had the highest average SUS score of 89.2, whereas MyDietCoach had the lowest SUS score of 46.7. Some variations in features were noted between Android and iOS versions of the same apps, mainly for MyDietCoach, which affected the SUS score. App features varied considerably, yet all of the apps had features consistent with Beliefs about Capabilities and thus have the potential to promote self-efficacy by helping individuals track their diet and progress toward goals. None of the apps allowed for tracking of emotional factors that may be associated with diet patterns. The presence of behavior change domain features tended to be weakly correlated with greater usability, with R2 ranging from 0 to .396. The exception to this was features related to the Reinforcement domain, which were correlated with less usability. Comparing the apps with the USDA reference for a 3-day diet, the average differences were 1.4% for calories, 1.0% for carbohydrates, 10.4% for protein, and -6.5% for fat. CONCLUSIONS Almost all reviewed diet-tracking apps scored well with respect to usability, used a variety of behavior change constructs, and accurately coded calories and carbohydrates, allowing them to play a potential role in dietary intervention studies.

Abstract
Atopic dermatitis (AD) is one of the most common chronic inflammatory diseases and is also one of the most frequent reasons to consult a dermatologist. Over the past few years there has been a rapidly growing understanding of the cellular, molecular and immunological relationships as well as genetic variations, which leads to a better comprehension of the disease. Consequently, there are innovative targeted therapies in clinical studies or already approved for therapy. To make reasonable use of the new targeted therapies a good understanding of the pathogenesis is very important. In the future, stratification of patients with AD and the resulting personalized therapies will gain in importance. This review depicts the up to date state of knowledge on the complex pathogenesis of AD.

Abstract
PURPOSE OF REVIEW Food allergy is defined as an adverse health effect arising from a specific immune response that occurs reproducibly on exposure to a given food. Food intolerance, certain gastrointestinal or systemic diseases are often confused with or mislabeled as food allergy because of symptomatic similarity and general improvement from food avoidance. The differences between these diseases are crucial. RECENT FINDINGS Compared with many food-related diseases that are isolated to gastrointestinal organs, food allergy can affect not only local but the whole immune system and may lead to a life-threatening allergic reaction, known as anaphylaxis. In this review, the differentiation between food allergy, food intolerance, and other comparable diseases is discussed. SUMMARY With recent medical advances reflecting on the importance of accurate diagnosis in food hypersensitivity, healthcare providers who are treating food hypersensitivity should familiarize with latest science progress, identify and treat active disease, and refer to appropriate specialists if needed.

Abstract
Atopic dermatitis is a chronic, relapsing, inflammatory skin disease that usually appears in early childhood and develops into a heterogeneous disease during childhood. The clinical course and treatment for atopic dermatitis can differ according to its phenotype and/or endotype. This study aimed to identify clinical phenotypes of atopic dermatitis in early childhood. Data were obtained from 572 children under 3 years of age with atopic dermatitis. Cluster analysis applied to 11 variables, and we identified four clusters of atopic dermatitis. Children in cluster A (n = 141) had early-onset atopic dermatitis with high blood eosinophil counts, serum total immunoglobulin E and rates of sensitization to food allergens. Children in cluster B (n = 218) had early-onset atopic dermatitis with low blood eosinophil counts, serum total immunoglobulin E and rates of sensitization to both food and inhalant allergens. Children in cluster C (n = 53) had early-onset atopic dermatitis with high C-reactive protein levels and white blood cell counts. Children in cluster D (n = 160) had middle-onset atopic dermatitis with high serum total immunoglobulin E and rates of sensitization to inhalant allergens. Cluster A had the highest Scoring for Atopic Dermatitis and transepidermal water loss values. Age at onset, age at diagnosis, white blood cell count, eosinophil count, C-reactive protein and serum total immunoglobulin E level were the strongest predictors of cluster assignment. Analysis of these six variables alone resulted in correct classification of 95.5% of the subjects. These results support the heterogeneity of atopic dermatitis, even in early childhood.

Abstract
BACKGROUND Recent studies have suggested that removing foods from the diet to manage atopic dermatitis (AD), based on positive allergy test results, may lead to immediate allergic reactions on reintroduction of that food. OBJECTIVE To examine the frequency of oral food challenge (OFC) failures among foods removed from the diet as suspected AD triggers, focusing on the 5 major food allergens in the United States. METHODS OFCs to egg, milk, peanut, soy, and wheat, performed from 2008 to 2014, at a children's hospital's allergy clinics, were reviewed. OFCs were offered based on history and laboratory values. Reasons for food avoidance were classified as food allergy (IgE-mediated reaction occurring within 2 hours); sensitization only (lack of introduction because of positive test results); and removal because of test results during AD evaluation. RESULTS There were 442 OFCs performed, with 89 failures (20.1%). Reasons for OFCs included a history of food allergy (320 of 442 [72.4%]), food sensitization without any introduction (77 of 442 [17.4%]), and AD (45 of 442 [10.2%]). OFC failures among those who had food allergy (70 of 320 [21.9%]), sensitization only (13 of 77 [16.9%]), and suspected AD trigger (6 of 45 [13.3%]) did not significantly differ (P = .63). Wheat was more likely to be avoided than the other 4 foods for AD concerns (P < .001). CONCLUSION The frequency of OFC failure among those who removed foods suspected as AD triggers was 13.3%, indicating a loss of tolerance. Restriction of foods to manage AD must be done with caution and close monitoring.
