Abstract
PURPOSE OF REVIEW To review the updated 2023 Allergy Immunology Joint Task Force on Practice Parameters (JTFPP) GRADE and Institute of Medicine (IOM) Based Guidelines for the management of atopic dermatitis. RECENT FINDINGS Topical corticosteroids and/or calcineurin inhibitors are recommended in individuals with atopic dermatitis refractory to moisturizer alone and may be used to maintain remission after acute flare control is achieved. Calcineurin inhibitors are a class of immunosuppressants used to effectively manage different autoimmune disorders. Bleach baths and allergen immunotherapy may be beneficial for individuals with moderate-to-severe disease, while elimination diets, azathioprine, methotrexate, mycophenolate, and systemic corticosteroids are not recommended. Dupilumab is strongly recommended for refractory atopic dermatitis. Oral Janus kinase (JAK) inhibitors carry significant risks; however, this class of medicines may be considered in cases of severe or refractory atopic dermatitis with intolerance to dupilumab. Patient preferences regarding cost, availability, feasibility, and tolerability should be integrated into all treatment plans using a shared decision-making approach. SUMMARY The 2023 JTFPP Atopic Dermatitis Guidelines offer up-to-date guidance for the management of atopic dermatitis of varying severity in infants, children, and adults.

A quantitative systems pharmacology workflow toward optimal design and biomarker stratification of atopic dermatitis clinical trials. J Allergy Clin Immunol 2024; 153:1330-1343.

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

Abstract
BACKGROUND Guidance addressing atopic dermatitis (AD) management, last issued in 2012 by the American Academy of Allergy, Asthma and Immunology/American College of Allergy, Asthma and Immunology Joint Task Force, requires updating as a result of new treatments and improved guideline and evidence synthesis methodology. OBJECTIVE To produce evidence-based guidelines that support patients, clinicians, and other decision-makers in the optimal treatment of AD. METHODS A multidisciplinary guideline panel consisting of patients and caregivers, AD experts (dermatology and allergy/immunology), primary care practitioners (family medicine, pediatrics, internal medicine), and allied health professionals (psychology, pharmacy, nursing) convened, prioritized equity, diversity, and inclusiveness, and implemented management strategies to minimize influence of conflicts of interest. The Evidence in Allergy Group supported guideline development by performing systematic evidence reviews, facilitating guideline processes, and holding focus groups with patient and family partners. The Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach informed rating the certainty of evidence and strength of recommendations. Evidence-to-decision frameworks, subjected to public comment, translated evidence to recommendations using trustworthy guideline principles. RESULTS The panel agreed on 25 recommendations to gain and maintain control of AD for patients with mild, moderate, and severe AD. The eAppendix provides practical information and implementation considerations in 1-2 page patient-friendly handouts. CONCLUSION These evidence-based recommendations address optimal use of (1) topical treatments (barrier moisturization devices, corticosteroids, calcineurin inhibitors, PDE4 inhibitors [crisaborole], topical JAK inhibitors, occlusive [wet wrap] therapy, adjunctive antimicrobials, application frequency, maintenance therapy), (2) dilute bleach baths, (3) dietary avoidance/elimination, (4) allergen immunotherapy, and (5) systemic treatments (biologics/monoclonal antibodies, small molecule immunosuppressants [cyclosporine, methotrexate, azathioprine, mycophenolate, JAK inhibitors], and systemic corticosteroids) and UV phototherapy (light therapy).

The Association of Oleic Acid and Dexamethasone Acetate into Nanocapsules Enables a Reduction in the Effective Corticosteroid Dose in a UVB Radiation-Induced Sunburn Model in Mice. Pharmaceutics 2024; 16:176. [PMID: 38399236 PMCID: PMC10892665 DOI: 10.3390/pharmaceutics16020176] [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: 12/18/2023] [Revised: 01/22/2024] [Accepted: 01/23/2024] [Indexed: 02/25/2024] Open
Abstract
Dexamethasone has a high anti-inflammatory efficacy in treating skin inflammation. However, its use is related to the rebound effect, rosacea, purple, and increased blood glucose levels. Nanotechnology approaches have emerged as strategies for drug delivery due to their advantages in improving therapeutic effects. To reduce dexamethasone-related adverse effects and improve the anti-inflammatory efficacy of treatments, we developed nanocarriers containing this corticosteroid and oleic acid. Nanocapsules and nanoemulsion presented dexamethasone content close to the theoretical value and controlled dexamethasone release in an in vitro assay. Gellan gum-based hydrogels were successfully prepared to employ the nanostructured systems. A permeation study employing porcine skin showed that hydrogels containing non-nanoencapsulated dexamethasone (0.025%) plus oleic acid (3%) or oleic acid (3%) plus dexamethasone (0.025%)-loaded nanocapsules provided a higher amount of dexamethasone in the epidermis compared to non-nanoencapsulated dexamethasone (0.5%). Hydrogels containing oleic acid plus dexamethasone-loaded nanocapsules effectively inhibited mice ear edema (with inhibitions of 89.26 ± 3.77% and 85.11 ± 2.88%, respectively) and inflammatory cell infiltration (with inhibitions of 49.58 ± 4.29% and 27.60 ± 11.70%, respectively). Importantly, the dexamethasone dose employed in hydrogels containing the nanocapsules that effectively inhibited ear edema and cell infiltration was 20-fold lower (0.025%) than that of non-nanoencapsulated dexamethasone (0.5%). Additionally, no adverse effects were observed in preliminary toxicity tests. Our study suggests that nanostructured hydrogel containing a reduced effective dose of dexamethasone could be a promising therapeutic alternative to treat inflammatory disorders with reduced or absent adverse effects. Additionally, testing our formulation in a clinical study on patients with skin inflammatory diseases would be very important to validate our study.

Abstract
Atopic dermatitis (AD) has been increasing in prevalence over the past few decades; however, AD has never been analyzed using a bibliometric approach. We searched for AD studies in the dermatology and allergy category of the Web of Science and SCOPUS databases using the keywords "atopic dermatitis", "eczema", and "atopy". In total, 53,460 documents were retrieved. We analyzed annual publication trends and performed keyword and co-authorship network analyses. The annual number of AD publications has increased over the years. Asthma, food allergies, the skin barrier, IgE, and epidemiology have received extensive attention. The keywords 'allergic rhinitis', 'child(ren)', 'quality of life', and 'probiotics' have become more commonly used in recent years. AD research has been led by only a few countries, such as the USA, Germany, and the UK, and longstanding research topics such as asthma, allergy, and the immune system continue to be important. We suggest that global collaborations, research in developing countries, and research that is more holistic (thus exploring how genes, the immune system, the environment, and the microbiome together impact AD) are necessary.

Abstract
Pediatric atopic dermatitis (AD) is a chronic, relapsing inflammatory skin disease, affecting 20% of children all over the world especially in developed countries. The global prevalence of AD in children has been increasing over recent years. This chronic inflammatory skin disease causes economic and social burden to the family. The exact cause of AD is not known, however recent studies suggest that the imbalance of microflora present in the gut leads to AD. The current treatment of AD involves the application of moisturizer, topical corticosteroids, antihistamines and antibiotics. This line of treatment of AD in children has many side effects. An alternative novel therapeutic approach has to be explored to combat this chronic skin disease. In recent years, there has been increasing interest in the use of probiotics in the modulation of gut microbiota for the management of AD. Many research studies showed that the administration of probiotics gives positive results in the prevention and treatment of AD in children, however, the results are not consistent and conclusive. In this review, the phenomenon that the dysbiosis of the gut flora contributes to the development of AD is addressed and clinical evidence of probiotics in the prevention and treatment of AD children is also summarised.

Abstract
Skin, the largest organ in the human body, provides several important functions, including providing protection from mechanical impacts, micro-organisms, radiation and chemicals; regulation of body temperature; the sensations of touch and temperature; and the synthesis of several substances including vitamin D, melanin, and keratin. Common dermatological disorders (CDDs) include inflammatory or immune-mediated skin diseases, skin infection, skin cancer, and wounds. In the treatment of skin disorders, topical administration has advantages over other routes of administration, and polymers are widely used as vehicles to facilitate the delivery of topical therapeutic agents, serving as matrices to keep therapeutic agents in contact with the skin. Nitric oxide (NO), a cellular signalling molecule, has attracted significant interest in treating a broad spectrum of diseases, including various skin disorders. However, there are a number of challenges in effectively delivering NO. It must be delivered in a controlled manner at sufficient concentrations to be efficacious and the delivery system must be stable during storage. The use of polymer-based systems to deliver NO topically can be an effective strategy to overcome these challenges. There are three main approaches for incorporating NO with polymers in topical delivery systems: (i) physical incorporation of NO donors into polymer bases; (ii) covalent attachment of NO donors to polymers; and (iii) encapsulation of NO donors in polymer-based particles. The latter two approaches provide the greatest control over NO release and have been used by numerous researchers in treating CDDs, including chronic wounds and skin cancer.

Abstract
INTRODUCTION The ubiquitously expressed nonhistone nuclear protein high-mobility group box protein 1 (HMGB1) has different functions related to posttranslational modifications and cellular localization. In the nucleus, HMGB1 modulates gene transcription, replication and DNA repair as well as determines chromosomal architecture. When the post-transcriptional modified HMGB1 is released into the extracellular space, it triggers several physiological and pathological responses and initiates innate immunity through interacting with its reciprocal receptors (i.e., TLR4/2 and RAGE). The effect of HMGB1-mediated inflammatory activation on different systems has received increasing attention. HMGB1 is now considered to be an alarmin and participates in multiple inflammation-related diseases. In addition, HMGB1 also affects the occurrence and progression of tumors. However, most studies involving HMGB1 have been focused on adults or mature animals. Due to differences in disease characteristics between children and adults, it is necessary to clarify the role of HMGB1 in pediatric diseases. METHODS AND RESULTS Through systematic database retrieval, this review aimed to first elaborate the characteristics of HMGB1 under physiological and pathological conditions and then discuss the clinical significance of HMGB1 in the pediatric diseases according to different systems. CONCLUSIONS HMGB1 plays an important role in a variety of pediatric diseases and may be used as a diagnostic biomarker and therapeutic target for new strategies for the prevention and treatment of pediatric diseases.

Abstract
The skin is one of the crucial body organs with anatomy and physiology linked to various disorders including congenital and acquired diseases. Nowadays, mesenchymal stem cell (MSCs)- based therapy has appeared as a promising therapeutic field, in which many see opportunities to cure the costliest and incurable diseases. However, one question to be asked is that if the use of MSCs in clinical trials studies and diseases treatment has improved. In this study, the clinical trials using MSCs in skin diseases were reviewed. A remarkable number of clinical trial studies are in progress in this field; however, only a few of them have led to tangible benefits for patients. The relevant papers and ongoing clinical trials that address MSC's therapeutic goals for various skin disorders were examined. This review can be very useful for both the dermatologists and basic skin researchers interested in contributing to stem cell-based therapeutic researches in the area of skin disorders.

Abstract
Allergic diseases have in common a dysfunctional epithelial barrier, which allows the penetration of allergens and microbes, leading to the release of type 2 cytokines that drive allergic inflammation. The accessibility of skin, compared with lung or gastrointestinal tissue, has facilitated detailed investigations into mechanisms underlying epithelial barrier dysfunction in atopic dermatitis (AD). This Review describes the formation of the skin barrier and analyzes the link between altered skin barrier formation and the pathogenesis of AD. The keratinocyte differentiation process is under tight regulation. During epidermal differentiation, keratinocytes sequentially switch gene expression programs, resulting in terminal differentiation and the formation of a mature stratum corneum, which is essential for the skin to prevent allergen or microbial invasion. Abnormalities in keratinocyte differentiation in AD skin result in hyperproliferation of the basal layer of epidermis, inhibition of markers of terminal differentiation, and barrier lipid abnormalities, compromising skin barrier and antimicrobial function. There is also compelling evidence for epithelial dysregulation in asthma, food allergy, eosinophilic esophagitis, and allergic rhinosinusitis. This Review examines current epithelial barrier repair strategies as an approach for allergy prevention or intervention.

Abstract
The multitude of treatment options for atopic dermatitis (AD) makes management frustrating for providers and patients. Eczema action plans (EAPs) have been proposed to improve parental and provider management. We developed a single-site randomized controlled trial to evaluate the impact of an EAP on quality of life (QOL), provider knowledge, and comfort with AD management. Providers were randomized into an EAP-use group and a traditional care group. All patients completed validated AD QOL surveys, and those with AD were verbally administered the survey 1 month later. Providers' perceptions on managing AD were compared in the EAP and usual use groups. Parents in the EAP group demonstrated a significantly increased understanding of AD treatment, and providers in the EAP group had a significantly increased understanding and management of AD. The EAP is a feasible tool that can be integrated into a busy clinic practice with a positive impact on physicians and patients.

Abstract
SHARPIN is an important component of the linear ubiquitin chain assembly complex (LUBAC). Loss of function of SHARPIN results in eosinophilic inflammation in multiple organs including skin with Th2 -dominant cytokines and dysregulated development of lymphoid tissues in mice. The clinicopathological features are similar to atopic dermatitis (AD) in humans. In order to investigate the potential role of SHARPIN in the pathogenesis of AD, we performed genetic association study of the genotypes and haplotypes as well as SHARPIN's expression between AD cases and controls. We found three mutations (g.480G>A, g.4576A>G and g.5070C>T) in patient group, and significantly decreased expression in AD lesions, suggesting a primary role of SHARPIN during AD development. Lentivirus-mediated in vitro assays identified that knockdown of SHARPIN can induce elevated expression of IL-33 and its orphan receptor ST2, FLG and STAT3 and NF-κB inactivation in HaCaT keratinocytes, which has been widely evidenced in regulating AD development. ST2 expression was highly induced in SHARPIN-silenced HaCaT keratinocytes after the combined stimulation of IL-4 and IL-13. Our in vivo and in vitro findings implicated that SHARPIN may be a novel participant in the pathogenesis and/or new therapeutic target of AD.

Abstract
Atopic dermatitis (AD) is the most common itchy dermatosis that affects millions of children and adults worldwide. Chronic itch in this condition has significant impact on measures of quality of life, such as sleep. Treating itch in AD has been challenging for decades, but new drugs have emerged in the last year with significant anti-pruritic effect. The optimal treatment regimen for atopic itch addresses barrier dysfunction, inflammation, neural hypersensitivity, and the itch-scratch cycle. Topical moisturizers remain the foundation of treatment and should be used by all patients with AD-associated pruritus. Step-wise therapy, from topical anti-inflammatory creams to systemic monoclonal antibodies and immunosuppressants, is recommended. There are multiple adjuvant therapies that can be used, especially to target itch in the setting of minimal skin inflammation. Finally, patient education, sleep management, and stress relief are important components to optimize outcomes. This review assesses the latest advances and treatment recommendations for pruritus in AD. Finally, suggested therapeutic ladders and emerging treatments are discussed.

Abstract
OBJECTIVE To provide an overview of janus kinase (JAK), chemoattractant receptor homologous molecule expressed on TH2 cells (CRTH2), and phosphodiesterase 4 (PDE4) inhibitors in allergic disorders. DATA SOURCES PubMed literature review. STUDY SELECTIONS Articles included in this review discuss the emerging mechanism of action of small molecule inhibitors and their use in the treatment of atopic dermatitis (AD), asthma, and allergic rhinitis (AR). RESULTS Allergic diseases represent a spectrum of diseases, including AD, asthma, and AR. For decades, these diseases have been primarily characterized by increased TH2 signaling and downstream inflammation. In recent years, additional research has identified disease phenotypes and subsets of patients with non-Th2 mediated inflammation. The increasing heterogeneity of disease has prompted investigators to move away from wide-ranging treatment approaches with immunosuppressive agents, such as corticosteroids, to consider more targeted immunomodulatory approaches focused on specific pathways. In the past decade, inhibitors that target JAK signaling, PDE4, and CRTH2 have been explored for their potential activity in models of allergic disease and therapeutic benefit in clinical trials. Interestingly, although JAK inhibitors provide an opportunity to interfere with cytokine signaling and could be beneficial in a broad range of allergic diseases, current clinical trials are focused on the treatment of AD. Conversely, both PDE4 and CRTH2 inhibitors have been evaluated in a spectrum of allergic diseases. This review summarizes the varying degrees of success that these small molecules have demonstrated across allergic diseases. CONCLUSION Emerging therapies currently in development may provide more consistent benefit to patients with allergic diseases by specifically targeting inflammatory pathways important for disease pathogenesis.

Abstract
BACKGROUND Although mutations in the filaggrin (FLG) gene have been reported to predispose patients with atopic dermatitis (AD) skin infection susceptibility, to date, the data reported in the literature are still controversial. OBJECTIVE To evaluate the role of FLG polymorphisms expression and risk of developing a concomitant Molluscum contagiosum sustained skin infection in the pediatric population with AD. METHODS A total of 100 children with AD and 97 healthy children were enrolled. AD was diagnosed and assessed according to the validated European Task Force on Atopic Dermatitis. DNA samples of patients were analyzed for allelic variants in the promoter and coding exon of FLG. Genotyping was performed with polymerase chain reaction amplification and direct sequencing. RESULTS Sixteen FLG variants have been detected in 29% of patients with AD: 2 synonymous (rs79808464 and rs116222149), 12 missense (rs11584340, rs113136594, rs145828067, rs374910442, rs747005144, rs145627745, rs144209313, rs74129443, rs192455877, rs150957860, rs138055273, rs147472105), 1 stop gained (rs183942200), and 1 frameshift (rs 558269137). In contrast, only 13% of the control group reported FLG mutations (22 heterozygous variants). In addition, the age at disease onset correlated significantly with FLG variants (P < .001). In addition, the AD with FLG gene variants (rs145627745, rs79808464, rs150957860, rs145828067, rs747005144, rs374910442, rs138055273, rs183942200, rs11584340, and rs113136594) reported moderate to severe Scoring Atopic Dermatitis scores. Finally, the AD group and the AD plus M contagiosum skin infection group had a significant association with FLG mutations when compared with the control group (P < .01). CONCLUSION FLG mutations are associated with early onset of AD, more severe clinical course of disease, and a significantly increased risk of M contagiosum sustained skin infection.

Abstract
Atopic dermatitis (AD) is the most common pediatric skin disease. AD has a significant effect on patient and family quality of life caused by intense pruritus, sleep disruption, dietary and nutritional concerns, and psychological stress associated with the disease and its management. Multidisciplinary approaches to AD care have been developed in appreciation of the complex interplay among biological, psychological, behavioral, and dietary factors that affect disease control and the wide range of knowledge, skills, and support that patients and families require to effectively manage and cope with this condition. Common components of multidisciplinary treatment approaches include medical evaluation and management by an AD specialist, education and nursing care, psychological and behavioral support, and nutritional assessment and guidance. Models of care include both clinical programs and structured educational groups provided as adjuncts to standard clinical care. Available evidence suggests beneficial effects of multidisciplinary interventions in improving disease severity and quality of life, particularly for patients with moderate-to-severe disease. Additional research is needed to identify the best candidates for the various multidisciplinary approaches and evaluate the cost-effectiveness of these programs.

Abstract
BACKGROUND Complementary and alternative interventions are becoming increasingly utilized as adjuncts to conventional treatment of atopic dermatitis (AD). While the number of studies continues to grow, the vastness of the subject coupled with the relatively poor quality and small size of the studies limit their usefulness to clinicians. PURPOSE Our aim was to comprehensively review randomized controlled trials (RCTs) of complementary and alternative therapies for AD. METHODS Searches were performed on PubMed, the Cochrane Central Register of Controlled Trials, EMBASE, and the Global Resource for EczemA Trial (GREAT) databases, focusing on RCTs of alternative or complementary AD therapies, with a sample size of ≥10, through March 2015 and limited to the English language. A total of 70 manuscripts met the inclusion criteria and were included in the final analysis. RESULTS There is at least some level I evidence to support the use of acupuncture and acupressure, stress-reducing techniques such as hypnosis, massage, and biofeedback, balneotherapy, herbal preparations (with many important caveats), certain botanical oils, oral evening primrose oil, vitamin D supplementation, and topical vitamin B12. Many other therapies either have sufficient data to suggest that they are ineffective, or simply do not have enough evidence to formulate a verdict. CONCLUSIONS Careful review of the literature reveals several promising therapies in this domain; such findings may help direct further research that is necessary to bolster clinical recommendations for alternative or complementary treatments of AD.

Abstract
Atopic dermatitis (AD) is a chronic inflammatory skin disease that affects up to 25% of children and 10% of adults. The skin of patients with moderate to severe AD is characterized by significant barrier disruption and T helper 2 (Th2)-driven inflammation, which are thought to play a significant role in the pathogenesis of AD. Current management of AD is aimed at suppressing the inflammatory response and restoring the barrier function of the skin, reducing exacerbations, and preventing secondary skin infections. Combinations of treatment strategies are used to alleviate the symptoms of the disease; however, resolution is often temporary, and long-term usage of some of the medications for AD can be associated with significant side effects. Antibody therapies previously approved for other inflammatory diseases have been evaluated in patients with AD. Unfortunately, they have often failed to result in significant clinical improvement. Monoclonal antibodies and novel small molecules currently in development may provide more consistent benefit to patients with AD by specifically targeting the immune and molecular pathways important for the pathogenesis of AD. Here we review the state-of-the-art therapeutics targeting the Th2 axis in AD.

Abstract
Atopic dermatitis (AD) is a common, recurrent, chronic inflammatory skin disease that is a cause of considerable economic and social burden. Its prevalence varies substantially among different countries with an incidence rate proclaimed to reach up to 20% of children in developed countries and continues to escalate in developing nations. This increased rate of incidence has changed the focus of research on AD toward epidemiology, prevention, and treatment. The effects of probiotics in the prevention and treatment of AD remain elusive. However, evidence from different research groups show that probiotics could have positive effect on AD treatment, if any, that depend on multiple factors, such as specific probiotic strains, time of administration (onset time), duration of exposure, and dosage. However, till date we still lack strong evidence to advocate the use of probiotics in the treatment of AD, and questions remain to be answered considering its clinical use in future. Based on updated information, the processes that facilitate the development of AD and the topic of the administration of probiotics are addressed in this review.

Abstract
Atopic eczema (AE) is a chronic, inflammatory skin disorder which usually develops in early childhood. In spite of intensive investigations, the causes of AE remain unclear, but are likely to be multifactorial in nature. Environmental factors or genetic-environmental interactions seem to play a key role in disease progression. Among various measures of AE managment, cutaneous hydration, which improves barrier function and relieve itchiness, may be helpful to reduce the need for topical steroid use and therefore should be used as a basic treatment. Avoiding aggravating factors is also a basic treatment of AE. Standard medical treatment with a pharmacologic approach may be necessary if basic treatment fails to control symptoms satisfactorily. Recently, more attention is given to a proactive therapeutic by regular intermittent application of low potency steroids or topical calcineurin inhibitors to prevent new flares. Furthermore, various targeted biologics are being introduced for AE control and are proposed as promising therapies. This paper provides a summary of the recent literature on the manangement of AE and a treatment guideline.

Abstract
BACKGROUND Case reports suggest that children with food-triggered atopic dermatitis (AD) on elimination diets may develop immediate reactions on accidental ingestion or reintroduction of an avoided food. OBJECTIVE The objective of this study was to systematically study the incidence and risk factors associated with these immediate reactions. METHODS A retrospective chart review of 298 patients presenting to a tertiary-care allergy-immunology clinic based on concern for food-triggered AD was performed. Data regarding triggering foods, laboratory testing, and clinical reactions were collected prospectively from the initial visit. Food-triggered AD was diagnosed by an allergist-immunologist with clinical evaluation and laboratory testing. We identified immediate reactions as any reaction to a food for which there was evidence of sIgE and for which patients developed timely allergic signs and symptoms. Differences between children with and without new immediate reactions were determined by a Mann-Whitney, χ(2), or Fisher's exact test as appropriate. RESULTS A total of 19% of patients with food-triggered AD and no previous history of immediate reactions developed new immediate food reactions after initiation of an elimination diet. Seventy percent of reactions were cutaneous but 30% were anaphylaxis. Cow's milk and egg were the most common foods causing immediate-type reactions. Avoidance of a food was associated with increased risk of developing immediate reactions to that food (P < .01). Risk was not related to specific IgE level nor a specific food. CONCLUSION A significant number of patients with food-triggered AD may develop immediate-type reactions. Strict elimination diets need to be thoughtfully prescribed as they may lead to decreased oral tolerance.

Abstract
Pediatric eczema is a common disease which causes economic and social burden. Its incidence differs among the societies, with an incidence reported to reach up to 20% in developed countries. Eczema is the first allergic disease seen in the childhood, and it is recognized as a precursor for the development of atopic diseases such as asthma, allergic rhinitis, and food allergy in the forthcoming years of children. Increased incidence of eczema in recent years has led to new research in epidemiology, prevention, and intervention of this disease. It is no doubt important to treat itching, rash, and excoriation of the skin; however, treatment of pediatric eczema should not be considered only as a treatment of skin lesions. Considering skin treatment as the tip of the iceberg, proper management of the allergic processes can be accepted as the rest of the iceberg. The role of probiotics in the prevention of atopic eczema is yet to be clarified. Evidence presented by existing studies suggesting that probiotics may prevent pediatric eczema is not strong enough. A positive effect, if any, may be related with onset time, dose, duration, and use of specific probiotics. To date, there is no strong evidence for use of probiotics in the treatment of eczema; however, administration of probiotics in breast-feeding mothers in the prenatal period and in infants in the postnatal period can be accepted as a safe and helpful option in the prevention of eczema. Nevertheless, there are still questions to be answered in the future about probiotic administration for eczema. Clinical use of probiotics will gradually become more widespread when these questions are answered. Based on current information, the administration of probiotics for pediatric eczema topic is addressed in this review.

Abstract
Atopic dermatitis, perhaps more than other dermatologic diseases, has garnered much attention in the realm of alternative medicine. This may be because its etiopathogenesis is incompletely understood, it is increasingly common, and it waxes and wanes often without clear precipitants, opening up many opportunities for misinterpretation. Herein we explore the evidence for a number of different alternative and complementary therapies, from textiles to vitamin supplements. By definition, none have enough data to be deemed "effective" in a conventional sense, but it is hopeful that some show promising evidence that may one day lead to mainstream acceptance with further research.

Abstract
Atopic dermatitis (AD) is a debilitating disease that significantly alters the quality of life for one in four children and one in 10 adults. Current management of AD utilizes combinations of treatments to symptomatically alleviate disease by suppressing the inflammatory response and restoring barrier function in the skin, reducing disease exacerbation and flare, and preventing secondary skin infections. Resolution is temporary and long-term usage of these treatments can be associated with significant side-effects. Antibody therapies previously approved for inflammatory diseases have been opportunistically evaluated in patients with atopic dermatitis; however, they often failed to demonstrate a significant clinical benefit. Monoclonal antibodies currently in development offer hope to those individuals suffering from the disease by specifically targeting immune and molecular pathways important for the pathogenesis of atopic dermatitis. Here, we review the underlying biological pathways and the state of the art in therapeutics in AD.

Abstract
Atopic dermatitis (AD) is a chronic, inflammatory skin condition which affects millions of people worldwide. It is most commonly seen in children but may also progress into adulthood. Management of this complex disease requires a multi-pronged approach which can address the myriad of issues which underscore its development. Avoidance of triggering factors is imperative in establishing consistent control of skin irritation while daily moisturization can be very effective in skin barrier repair and maintenance. Judicious use of anti-inflammatory medications has been shown to make a significant impact on both treatment as well as prevention of disease. Unfortunately, pruritus, a key feature of AD, has proven much harder to control. Finally, awareness of the risks of colonization and infection in patients with AD should be incorporated into their surveillance and management plans. While our understanding has progressed greatly regarding this disease, further research is still needed regarding future directions for both treatment and prevention.
