Abstract
Atopic dermatitis (AD) is a chronic inflammatory skin disease affecting both children and adults. The clinical picture of AD manifests in typical skin lesions, such as localized eczema and dry skin, with dominant, persistent itching that leads to sleep disturbances. The pathophysiology of AD has been extensively investigated with respect to epigenetic and genetic factors, skin barrier defects, as well as immunological and microbial disorders. However, to date, the involvement of extracellular matrix (ECM) elements has received limited attention. Collagen, a major component of the ECM, may serve as a therapeutic target for the future treatment of AD. This paper summarizes the role of collagens, which are the most abundant components of the extracellular matrix in AD.

Abstract
The epithelial barrier serves as a critical defense mechanism separating the human body from the external environment, fulfilling both physical and immune functions. This barrier plays a pivotal role in shielding the body from environmental risk factors such as allergens, pathogens, and pollutants. However, since the 19th century, the escalating threats posed by environmental pollution, global warming, heightened usage of industrial chemical products, and alterations in biodiversity have contributed to a noteworthy surge in allergic disease incidences. Notably, allergic diseases frequently exhibit dysfunction in the epithelial barrier. The proposed epithelial barrier hypothesis introduces a novel avenue for the prevention and treatment of allergic diseases. Despite increased attention to the role of barrier dysfunction in allergic disease development, numerous questions persist regarding the mechanisms underlying the disruption of normal barrier function. Consequently, this review aims to provide a comprehensive overview of the epithelial barrier's role in allergic diseases, encompassing influencing factors, assessment techniques, and repair methodologies. By doing so, it seeks to present innovative strategies for the prevention and treatment of allergic diseases.

Int J Med Inform 2023; 179:105226. [PMID: 37742400 DOI: 10.1016/j.ijmedinf.2023.105226] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/16/2023] [Revised: 09/16/2023] [Accepted: 09/18/2023] [Indexed: 09/26/2023]
Abstract
INTRODUCTION In the spring of 2021, a physician-supervised application (app) "Kayumidas© - Itchy Eye Alert" was released for allergy sufferers, which implements a function to predict pollen dispersal status for each user based on weather forecasts and notify users of the results. This app provides push notifications of warning levels of itchiness and other symptoms, countermeasures, and the time to use medication. However, no evaluation has been conducted to determine whether the use of app improves compliance with treatment. This study aimed to verify whether the use of a smartphone app is effective in relieving the symptoms of allergic conjunctivitis and rhinitis and how it changes patients' eye drop behavior. METHODS This was an investigator-initiated, observational, prospective cohort study that was conducted between February 2022 and May 2022. In 62 patients diagnosed with allergic conjunctivitis, the scores of nine subjective eye and nose symptoms (1-4) and eye itchiness (1-7) before and after using the app were compared using a questionnaire. The adherence scores for eye drops (1-4) were also investigated using a questionnaire. RESULTS The scores for all five ocular subjective symptoms and all four nasal subjective symptoms improved significantly after app use (p < 0.01). Both itching scores (4.1 ± 1.1 vs. 1.6 ± 0.5, p < 0.01) and eye drop compliance scores (2.0 ± 0.7 vs. 3.9 ± 0.3, p < 0.01) improved significantly after app use. CONCLUSION The use of the Kayumidas© app improved adherence to eye drops and the subjective symptoms of allergic conjunctivitis and rhinitis. Thus, app use effectively improves symptoms by changing behavior and improving self-care awareness regarding treatment in patients with allergic diseases.

Am J Clin Dermatol 2023:10.1007/s40257-023-00780-w. [PMID: 37184828 PMCID: PMC10184626 DOI: 10.1007/s40257-023-00780-w] [Citation(s) in RCA: 7] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 03/29/2023] [Indexed: 05/16/2023]
Abstract
BACKGROUND Topical treatments for atopic dermatitis (AD) used reactively often fail to achieve lasting disease control; many of these therapies are associated with safety concerns that limit long-term use. Crisaborole ointment, 2%, is a nonsteroidal phosphodiesterase 4 inhibitor for the treatment of mild-to-moderate AD that has potential as a long-term maintenance therapy. OBJECTIVE The aim was to evaluate the long-term efficacy and safety of crisaborole once daily (QD) compared to vehicle QD as a maintenance therapy to reduce the incidence of flares in patients with AD who previously responded to crisaborole twice daily (BID). METHODS CrisADe CONTROL was a randomized, double-blind, vehicle-controlled, 52-week, phase III study of patients aged ≥ 3 months with mild-to-moderate AD involving ≥ 5% treatable body surface area. Eligible patients received crisaborole BID during an open-label run-in period of up to 8 weeks. Responders were randomly assigned in the double-blind maintenance period to receive either crisaborole QD or vehicle QD. Responders were defined as patients who achieved Investigator's Static Global Assessment (ISGA) success (ISGA score of 0 [clear] or 1 [almost clear] with a ≥ 2-grade improvement) and ≥ 50% improvement in Eczema Area and Severity Index total score (EASI-50) from baseline. Patients who experienced a flare (ISGA score ≥ 2) during the double-blind maintenance period switched to crisaborole BID for up to 12 weeks. During this period, patients were assessed every 4 weeks; if the flare resolved (ISGA score ≤ 1), patients resumed their assigned treatment. The primary endpoint was flare-free maintenance until onset of the first flare. Key secondary endpoints were number of flare-free days, number of flares, and maintenance of pruritus response until onset of the first flare. The incidence of treatment-emergent adverse events was also analyzed. RESULTS Overall, 497 patients entered the open-label run-in period with crisaborole BID, of which 270 patients were randomized into the 52-week double-blind maintenance period of the study. Of the 270 patients, 135 were randomly assigned to the crisaborole QD group and 135 were randomly assigned to the vehicle QD group. Median time of flare-free maintenance was longer for patients who received crisaborole versus vehicle (111 vs 30 days, respectively; p = 0.0034). The mean number of flare-free days was higher for patients who received crisaborole versus vehicle (234.0 vs 199.4 days, respectively; p = 0.0346). The mean number of flares was lower for patients who received crisaborole versus vehicle (0.95 vs 1.36, respectively; p = 0.0042). No clear trend was observed in maintenance of pruritus response between crisaborole- and vehicle-treated patients. Crisaborole was well tolerated, with no new or unexpected safety findings when used as maintenance treatment. CONCLUSIONS Crisaborole QD was effective and well tolerated for long-term maintenance treatment and flare reduction in adult and pediatric patients with mild-to-moderate AD.

Real-world efficacy of proactive maintenance treatment with delgocitinib ointment twice weekly in adult patients with atopic dermatitis. Dermatol Ther 2022; 35:e15526.

Abstract
Previous studies have shown the efficacy of delgocitinib (DEL) ointment, a topical Janus kinase inhibitor, against atopic dermatitis (AD). However, there is no available information regarding the efficacy of DEL ointment in maintaining remission. Data of patients with AD who received remission maintenance therapy twice weekly with DEL or topical corticosteroid (TCS) on the affected skin of each upper limb were extracted from the medical records. Efficacy was assessed based on changes in pruritus numerical rating scale (NRS) score, stratum corneum hydration (SCH), erythema index (EI). Of 25 patients, four patients (16%) had eczema flare-ups on the TCS side and eight patients (32%) on the DEL side. The extent of change in each parameter between TCS- and DEL-treated areas of the skin did not differ significantly. The mean changes in the NRS and EI showed a slight improvement on the side treated with TCS and were slightly worse on the side treated with DEL. However, the SCH of the DEL group was maintained, while that of the TCS group worsened. TCS is more likely to be effective than DEL in terms of remission maintenance therapy. However, topical DEL is as effective as topical steroid in the maintenance therapy of AD in dry skin patients.

Abstract
Allergic diseases represent a global burden. Although the patho-physiological mechanisms are still poorly understood, epithelial barrier dysfunction and Th2 inflammatory response play a pivotal role. Barrier dysfunction, characterized by a loss of differentiation, reduced junctional integrity, and altered innate defence, underpins the pathogenesis of allergic diseases. Epithelial barrier impairment may be a potential therapeutic target for new treatment strategies Up now, monoclonal antibodies and new molecules targeting specific pathways of the immune response have been developed, and others are under investigation, both for adult and paediatric populations, which are affected by atopic dermatitis (AD), asthma, allergic rhinitis (AR), chronic rhinosinusitis with nasal polyps (CRSwNP), or eosinophilic esophagitis (EoE). In children affected by severe asthma biologics targeting IgE, IL-5 and against IL-4 and IL-13 receptors are already available, and they have also been applied in CRSwNP. In severe AD Dupilumab, a biologic which inhibits both IL-4 and IL-13, the most important cytokines involved in inflammation response, has been approved for treatment of patients over 12 years. While a biological approach has already shown great efficacy on the treatment of severe atopic conditions, early intervention to restore epithelial barrier integrity, and function may prevent the inflammatory response and the development of the atopic march.

Abstract
Atopic dermatitis is a common inflammatory skin disease that can affect both children and adults. It is a chronic disease with recurrent, highly pruritic eczematous lesions. Topical treatment with anti-inflammatory agents is the mainstay of treatment for atopic dermatitis, either in a reactive or proactive approach according to severity of the disease and always in combination with daily application of an emollient cream. Several studies have shown that proactive therapy with either topical corticosteroids or topical calcineurin inhibitors is significantly superior at reducing the number of flares and increasing the interval between flares compared with reactive therapy in patients with moderate and severe disease. The risk of side effects is considered low, and there seem to be no extra economic costs related to this treatment approach. Proactive therapy is an advisable treatment option for patients with moderate and severe atopic dermatitis to gain prolonged disease control; however, long-term safety data and data on when to stop do not yet exist.

Abstract
Most patients with psoriasis present with localized mild-to-moderate disease. In this case, the application of topical treatments in the first-line setting is recommended in most cases.Among different topical options, the fixed-dose combination of betamethasone dipropionate (BD) and vitamin D analogue (Cal) aerosol foam (Enstilar®, Leo Pharma) is approved as first-line topical therapy for the treatment of psoriasis in USA and the EU, due to its high efficacy and its favorable administration scheme.The PSO-LONG was the first trial to report on the long-term efficacy and safety of the Cal/DB foam treatment for the proactive management of psoriasis and now, the indications of Cal/BD foam included its use in the psoriasis maintenance treatment. However, the precise role of this treatment and the potential therapeutic schemes in the long-term management of psoriasis need further clarification.This Position Paper, authored by a group of Italian Expert Dermatologists, critically discusses the long-term management of psoriasis with Cal/BD foam in clinical practice. In particular, the biological rationale in the proactive treatment with Cal/BD foam and current evidence regarding this therapeutic approach are presented, along with its application also in patients with moderate-to-severe disease, difficult-to-treat lesions, or within combination regimens. In addition, strategies to improve adherence to long-term treatment of psoriasis are discussed.

Abstract
BACKGROUND Otitis externa is associated with a lack of bacterial/fungal diversity in atopic dermatitis. Clinical experience has shown that use of topical corticosteroids in the ear canal (EC) can prevent otitis. No data are available on the impact of this treatment on the EC microbiota. HYPOTHESIS/OBJECTIVES To observe the bacterial/fungal diversity in the EC and the clinical effect of topical corticosteroids administered over a four week period in atopic dogs without active otitis. ANIMALS Ten atopic dogs without active otitis. METHODS AND MATERIALS Mometasone was applied in the right EC, while the left was used as control. A clinical and cytological evaluation of the EC was performed. Swabs of each EC were analysed using next-generation sequencing methods. RESULTS At the beginning of the trial, variations in microbiota and mycobiota were observed between dogs and also within individuals. Statistically, no significant difference was observed in alpha and beta diversity between the treated and the untreated group over time. Clinically, right and left EC diversities were no different at Day (D)28 (P = 0.28). A significant difference was noted between D0 and D28 for the treated ears (P = 0.012) and not for the untreated ears (P = 0.63). No cytological evidence of microbes was found for treated ECs at D28. CONCLUSIONS AND CLINICAL RELEVANCE These data suggest that the use of topical corticosteroids as proactive treatment is unlikely to increase the risk of secondary microbial overgrowth. The positive clinical effect of this proactive treatment seems to be supported through cytological and otoscopic improvement.

Abstract
A common disease worldwide is known as atopic dermatitis (AD), named also as atopic eczema, which is a chronic recurrent complex inflammatory skin disorder. It affects 2–10% of the adult population and up to 20% of the pediatric population. The clinical AD picture appears in typically localized eczema and dry skin, and is dominated by a persistent pruritus followed by sleep disturbances. AD strongly impacts on the quality of life of AD patients and their families as well as on social and economic aspects. The pathogenesis of the disease is complex and consists of multiple interactions between immunological disturbances, skin barrier defect, and microbial dysbiosis with environmental influences. The treatment of AD reflects the pathogenetic disorders, starting from basic emollient therapy, and goes to topical anti-inflammatory regimens followed by phototherapy, systemic immunosuppressive drugs, and new biologic immunomodulators. This paper will thus summarize the novel collection of biological treatment JAK-STAT inhibitors dedicated to AD.

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

Abstract
BACKGROUND Topical psoriasis treatment relies on a reactive rather than a long-term proactive approach to disease relapse. OBJECTIVE Assess long-term efficacy and safety of proactive psoriasis management with twice-weekly calcipotriene 0.005%/betamethasone dipropionate 0.064% (Cal/BD) foam. METHODS Phase III trial (NCT02899962) included a 4-week open-label lead-in phase (Cal/BD foam once daily) and a 52-week, randomized, double-blind, maintenance phase. A total of 545 patients achieved treatment success (physician's global assessment "clear"/"almost clear," ≥2-grade improvement from baseline) and were randomized to proactive management (Cal/BD foam; n = 272) or reactive management (vehicle foam; n = 273) twice-weekly, with rescue treatment of Cal/BD foam once daily for 4 weeks upon relapse. Primary endpoint was time to first relapse (physician's global assessment "mild" or higher). RESULTS A total of 251 randomized patients (46.1%) completed the trial. Median time to first relapse was 56 days (proactive) and 30 days (reactive). Patients in the proactive group had an additional 41 days in remission compared with the reactive group over 1 year (P < .001). Number of relapses per year of exposure was 3.1 (proactive) and 4.8 (reactive). Cal/BD foam was well tolerated. LIMITATIONS Maintenance phase dropout rate (53.9%) was within the expected range but provides challenges in statistical analysis. CONCLUSION Long-term proactive management with Cal/BD foam demonstrated superior efficacy vs reactive management.

Abstract
INTRODUCTION Dupilumab is a treatment option newly licensed for adolescents with moderate to severe atopic dermatitis (AD). It reduces type 2 inflammation by blocking the shared receptor subunit for IL-4/-13. Dupilumab affects three disease mechanisms in atopic dermatitis: the skin barrier, the Th2-cell differentiation and the class switch to IgE. This report is based on a systematic literature search of the PubMed Database. AREAS COVERED Dupilumab showed promising results in improving AD signs, symptoms and quality of life in adolescents with moderate to severe AD. The safety profile of dupilumab in adolescents with moderate to severe AD closely resembled the known safety profile of dupilumab in adults with moderate to severe AD. Injection-site reactions and conjunctivitis were the relevant side-effects. Skin infections were less frequently observed compared to placebo. EXPERT COMMENTARY Dupilumab was approved by the Food and Drug Administration in March 2019 and by the European Medicines Agency in August 2019 for the treatment of adolescents with moderate to severe atopic dermatitis whose disease is not adequately controlled with topical therapies or when those therapies are not advisable. Since it is the first licensed drug it will likely become the reference drug for adolescents with moderate to severe AD.

Abstract
Atopic dermatitis is a chronic and recurrent inflammatory dermatosis with concomitant intensive pruritus, and is diagnosed both in children and adults. Atopic dermatitis-patients are predisposed to have bacterial, viral and fungal skin infections; they also suffer from an increased risk of developing food allergies (especially, at an infantile age), allergic rhinitis, or bronchial asthma (a so-called atopic march). Currently, an increasing atopic dermatitis incidence constitutes a serious medical problem that regards not only dermatology and allergology, but also paediatrics, and family medicine. The basis for atopic dermatitis treatment and prophylaxis is restoration of epidermal barrier functions by means of tailored emollients. Atopic dermatitis therapies should effectively eliminate clinical symptoms of the disease, prevent exacerbations as well as complications, and improve patients' quality of life.

Abstract
Given the inadequate overall awareness of the main disease features and treatment modalities of pruritus in pediatric patients with atopic dermatitis, a multidisciplinary Italian expert group met with the major aim of increasing knowledge of the condition for improved diagnosis and better management among specialists involved in disease management. Herein, the overall features of the condition are reviewed, along with its etiopathogenesis and symptoms. Likewise, management options are summarized, emphasizing the need for a multidisciplinary approach, minimally composed of a management team that includes a pediatrician, dermatologist, psychologist, play assistant, and dedicated nurse. In addition to more traditional therapies such as emollients as highlighted by European guidelines, therapeutic patient education in a group or individually is highly encouraged as it helps patients and their parents to better understand the disease and provide practical guidance for dressing and bandaging. It can also aid in outlining coping strategies for itching and sleep disturbance. The utility of distraction techniques should also be stressed as such educational interventions involving the child and their parents can substantially improve the overall quality of life. All approaches should be tailored according to patient age and clinical features and requires individualized strategy to ensure good adherence by both children and their parents. Thus, a holistic approach embracing systemic, topical and psychological interventions is advocated in order to provide patients and their caregivers the best possible care.

Abstract
BACKGROUND Atopic dermatitis (AD) is one of the most common allergic diseases in children. The aim of the study was to evaluate the ultrasound picture of lesional and non-lesional skin in children with AD. MATERIALS AND METHODS The study included a group of children with AD and a control group. Inclusion criteria were as follows: age 0-8 years and clinical diagnosis of AD. An ultrasound scanner with a 75 MHz transducer probe was used to produce B-mode skin images in lesions and non-lesional skin. The thickness and the echogenicity of epidermis, dermis, and subepidermal low-echogenic band (SLEB) were measured, and the ratio coefficient per body site was calculated. RESULTS Ultrasonography of non-lesional skin in children with AD showed uneven epidermis contour, a tendency to increased epidermis and decreased dermis thickness, and the SLEB was observed in 77% of cases. In lesions, there was an increased thickness and a decreased echogenicity of epidermis and dermis, and epidermis had irregular contours in most cases. The SLEB was in all lesions, showing greater thickness and lower echogenicity compared with non-lesional skin. CONCLUSION HF-USG of the skin allows visualizing the epidermal barrier disruption and inflammation in dermis in children with AD on the entire surface of the skin.

Abstract
Frontal fibrosing alopecia (FFA) is a primary cicatricial alopecia characterized by loss of follicular stem cells, fibrosis, and a receding frontotemporal hairline, with frequent loss of eyebrows, and less commonly, body hair involvement. Diagnosis is clinical and the disease most often affects postmenopausal women. Treatment is difficult with the goal of disease stabilization rather than hair regrowth due to the scarring nature of FFA. To date, there are no randomized controlled trials evaluating efficacy of treatments. Therefore, much of our knowledge is based on small retrospective studies. In this review, we highlight the various and most current treatment options for FFA, including 5-α-reductase inhibitors, intralesional steroids, hydroxychloroquine, topical steroids, topical calcineurin inhibitors, systemic retinoids, pioglitazone, oral antibiotics, minoxidil, excimer laser, and hair transplantation. Currently, 5-α-reductase inhibitors, intralesional steroids, and hydroxychloroquine have the highest level of evidence for treating FFA, while the remaining therapies have variable results and require further data to draw definitive conclusions.

Abstract
Atopic dermatitis (AD) is a common, chronic, relapsing-remitting inflammatory disease that can be challenging to treat. Patients with mild disease are usually managed well with good skin care practices including moisturization and appropriate bathing along with intermittent use of topical therapies such as topical corticosteroids and/or topical calcineurin inhibitors during flares. Patients with frequent flares may benefit from proactive application of topical therapies twice a week to the most troublesome areas. Patients with severe disease often present significant treatment challenges. Systemic therapies are usually required for severe AD but have varying degrees of success and can be associated with side-effect profiles that require counseling and close monitoring. Phototherapy has been shown to have success in treating moderate-to-severe AD, but several factors can limit its utility and efficacy including cost and access. New therapies are in development targeting specific pathways relevant for AD. Dupilumab was the first biologic treatment approved in North America, Europe, and Japan for adults with moderate-to-severe AD. Although this treatment can lead to rapid improvement in the majority of patients, there are inadequate responders. In this review, we discuss the clinical challenges and treatment options for moderate-to-severe refractory AD.

Abstract
Atopic dermatitis (AD) is a chronic, highly pruritic skin disorder, with a broad spectrum of clinical manifestations, characterized by abnormal skin barrier function. High-frequency ultrasonography (HF-USG) is an instrument with potential use in a variety of skin conditions. Previous studies on HF-USG in AD reported that apparently non-lesional skin also presents barrier defects. We aimed to assess lesional and non-lesional skin of AD patients with the use of HF-USG, focusing on skin barrier function and inflammation. We included a group of AD patients and a control group. On both we performed analysis with the use of HF-USG. The thickness of the subepidermal low-echogenic band (SLEB) and the skin echogenity were recorded for active lesions, as well as non-lesional skin in all subjects included. For AD patients the clinical severity was measured using SCORing Atopic Dermatitis and correlated with Dermatology Life Quality Index (DLQI). The mean thickness of the hypoechoic band was wider in the lesional skin of AD. In the non-lesional skin of AD patients SLEB was identified to appear, but it was thinner. The skin echogenity of the control group was higher than that of AD patients. Our results indicate that skin ultrasonography is able to assess specific modifications of the AD skin. A hypoechoic band in the non-lesional skin of some AD patients may indicate subclinical eczematous lesions.

The skin as a target for prevention of the atopic march. Ann Allergy Asthma Immunol 2019; 120:145-151.

Abstract
OBJECTIVE Allergic diseases have increased dramatically in the developed world during the past few decades, yet the understanding of risk factors and effective prevention approaches remain limited. In this review, we summarize the evidence supporting the hypothesis that skin-barrier impairment and early-life atopic dermatitis (AD) could play a causal role in the development of sensitization and subsequent food allergies and allergic airways disease (allergic asthma and rhinitis). We further discuss the potential to target the skin barrier as a means to lower the incidence of allergic disease. DATA SOURCES Review of published literature. STUDY SELECTIONS Narrative. RESULTS There is a strong link between AD and sensitization, food allergy, asthma, and allergic rhinitis, particularly AD that is severe and commences in the first 6 months of life. There also is emerging evidence that regular use of prophylactic emollients can significantly decrease the expression of AD, at least while treatment continues. Studies are exploring whether decreased AD expression might modulate the allergic response at a more fundamental level and potentially alter the association between early-life AD and subsequent development of food allergy and allergic airways disease. CONCLUSION Although at this point there is only indirect evidence that early-life emollient use might prevent AD and food allergy, early studies are encouraging. The results of high-quality prevention trials that are in progress are eagerly anticipated. If found to be effective, then neonatal emollient use could be a simple public health measure to lower the incidence of AD, food allergies, and allergic airways disease in future generations.

Abstract
This guideline was developed as a joint interdisciplinary European project, including physicians from all relevant disciplines as well as patients. It is a consensus-based guideline, taking available evidence from other guidelines, systematic reviews and published studies into account. This first part of the guideline covers methods, patient perspective, general measures and avoidance strategies, basic emollient treatment and bathing, dietary intervention, topical anti-inflammatory therapy, phototherapy and antipruritic therapy, whereas the second part covers antimicrobial therapy, systemic treatment, allergen-specific immunotherapy, complementary medicine, psychosomatic counselling and educational interventions. Management of AE must consider the individual clinical variability of the disease; highly standardized treatment rules are not recommended. Basic therapy is focused on treatment of disturbed barrier function by hydrating and lubricating topical treatment, besides further avoidance of specific and unspecific provocation factors. Topical anti-inflammatory treatment based on glucocorticosteroids and calcineurin inhibitors is used for flare management and for proactive therapy for long-term control. Topical corticosteroids remain the mainstay of therapy, whereas tacrolimus and pimecrolimus are preferred in sensitive skin areas and for long-term use. Topical phosphodiesterase inhibitors may be a treatment alternative when available. Adjuvant therapy includes UV irradiation, preferably with UVB 311 nm or UVA1. Pruritus is targeted with the majority of the recommended therapies, but some patients may need additional antipruritic therapy. Antimicrobial therapy, systemic anti-inflammatory treatment, immunotherapy, complementary medicine and educational intervention will be addressed in part II of the guideline.

Abstract
Atopic dermatitis (AD) is a chronic inflammatory, relapsing disease of the skin, characterized by intense pruritus, maculopapular or vesicular erythematous lesions and scaling, sometimes accompanied by oozing, crusts and/or lichenification that has a negative impact on patients' quality of life. Prevalence is higher in children, around 15%, and approximately 5% in adults. Before introducing systemic therapy, it is mandatory to review patients' adherence to the correct use of topical treatments (corticosteroids, calcineurin inhibitors or cresoborole) and/or phototherapy. Ensure that environmental measures are being taken care of, irritant or proven allergic substances are not in use and even if the diagnostic is correct. If all is being done and topical treatment with corticosteroid, emollients and phototherapy have not been sufficient to achieve a good control in AD of adults or children patients, it is time to consider systemic agents. Up to now, most of systemic treatments were based on immunosuppressive therapies, being cyclosporine A, the usually first choice for moderate-to-severe AD. Recently, biologic drugs have been developed and approved for AD, as dupilumab, and a whole new group of drugs is giving much hope for patients to have a better control of the disease with less side effects.

Abstract
Atopic dermatitis (AD) is a multifaceted disease that involves a complex interplay between the skin and the immune system. The course of the disease depends strongly on the genetic background of the patient and on yet poorly-defined environmental factors. Changes in lifestyle could be behind the dramatic rise in the prevalence of AD across continents; including hygienic conditions, food, social habits, skin microbiome or exposure to a number of allergens. Although AD typically develops in childhood and disappears after a few years, in a relatively large number of patients it continues into adulthood. Adult AD can also appear de novo but it is often underdiagnosed and its treatment can be challenging. New, highly effective drugs are being developed to manage moderate and severe forms of the disease in adults. In this review, we highlight the most recent developments in diagnostic tools, current insights into the mechanistic basis of this disease, and therapeutic innovations.

Abstract
INTRODUCTION Local adverse effects of steroid use and the burning sensation of calcineurin inhibitors impair patients' adherence to treatment and decrease the treatment response in atopic dermatitis (AD). Steroid phobia appears to be a psychological problem in patients with AD. Topical non-steroidal remedies are in demand. Areas covered: This manuscript reviews the current literature on preclinical and clinical studies regarding topical E6005/RVT-501, a novel phosphodiesterase 4 inhibitor. We also discuss the mechanistic background of E6005/RVT-501 in the treatment of AD. Expert opinion: Topical E6005/RVT-501 improves skin eruption and pruritus of pediatric and adult AD patients without any serious side effects. It is useful for mild to moderate lesions of AD in pediatric and adult patients. Topical E6005/RVT-501 is non-steroidal agent but its potency is equal to that of mild rank topical steroid, therefore, it may fit the demand of patients with steroid phobia. Its steroid-sparing effects may also be investigated in future clinical trials and may minimize the dose and frequency of topical steroids.

Abstract
Atopic dermatitis (AD) is among the most common inflammatory skin diseases in children and adults in industrialized countries. Up to one-third of adults (probably a smaller proportion in childhood) suffer from moderate-to-severe AD, whose recommended treatment is usually based on systemic therapies. The currently available therapeutics are limited, and AD management becomes challenging in most cases. Over the last few years, new advances in the understanding of AD pathogenic mechanisms and inflammatory pathways have led to the identification of specific therapeutic targets and new molecules have been tested. Dupilumab is a fully human monoclonal antibody directed against the IL-4 receptor α subunit that is able to block the signaling of both IL-4 and IL-13 and achieve rapid and significant improvements in adults with moderate-to-severe AD. Dupilumab is ready to inaugurate a long and promising biological target treatment option for Th2 cell-mediated atopic immune response that characterizes AD.

Abstract
Treatment of children diagnosed with atopic dermatitis (AD) is an art. Age-dependent barrier function, skin physiology, body surface:weight ratio, the compliance of patient and caregivers, and legal considerations related to the license status of topical and systemic drugs must be considered. Mild to moderate AD can usually be treated sufficiently with a personalized regimen of emollients and topical anti-inflammatory therapy consisting of topical corticosteroids (TCSs) or topical calcineurin inhibitors. Emollients containing bacterial lysates, tailored wet wrap regimen, and proactive therapy with tacrolimus ointment or some TCSs are new developments in the field. Severe AD may need systemic therapy, but all currently available systemic agents for severe AD are either not licensed for children or not advisable on the long term, or both. Therapeutic patient education based on structured, interactive sessions with patients or caregivers and a multidisciplinary team is highly effective. This publication summarizes the current therapeutic options used in the pediatric AD population.

[PMID: 26967585 DOI: 10.1111/ijd.13291] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/03/2015] [Revised: 09/29/2015] [Accepted: 12/19/2015] [Indexed: 11/29/2022]
Abstract
BACKGROUND Atopic dermatitis (AD) is a chronic or relapsing inflammatory disorder of the skin that frequently precedes asthma and allergic disorders. This study aimed to identify candidate genes related to AD using bioinformatic methods. METHODS The microarray data of GSE32924, including 12 nonlesional AD (ANL) and 13 lesional AD (AL) skin samples obtained from 14 patients with AD as well as eight other normal human skin samples, was downloaded from the Gene Expression Omnibus database. Differentially expressed genes (DEGs) were screened in ANL and AL skin samples compared with normal controls, followed by gene ontology (GO) and pathway enrichment analyses. Furthermore, the selected overlapping DEGs were analyzed to identify co-expressed genes, and a co-expression network was established. GeneCodis database was selected for functional annotation of the differentially co-expressed genes and a regulatory network was constructed. RESULTS Compared with normal controls, 438 DEGs were identified in ANL skin samples and were mainly enriched in two pathways and the GO terms associated with epidermis development. Besides, 779 DEGs were identified in AL skin samples and were mainly enriched in four pathways and GO terms associated with immune response. Stimulated by retinoic acid 13 (STRA13), presenilin enhancer gamma secretase subunit (PSENEN), and nucleosome assembly protein 1-like 2 (NAP1L2) were significantly enriched by integration analysis of the co-expression and regulatory network. CONCLUSION Genes STRA13, PSENEN, and NAP1L2 were presumed to play critical roles in AD and they may serve as potential targets for the treatment of AD.

Abstract
The Italian Consensus Conference on clinical management of atopic dermatitis in children reflects the best and most recent scientific evidence, with the aim to provide specialists with a useful tool for managing this common, but complex clinical condition. Thanks to the contribution of experts in the field and members of the Italian Society of Pediatric Allergology and Immunology (SIAIP) and the Italian Society of Pediatric Dermatology (SIDerP), this Consensus statement integrates the basic principles of the most recent guidelines for the management of atopic dermatitis to facilitate a practical approach to the disease. The therapeutical approach should be adapted to the clinical severity and requires a tailored strategy to ensure good compliance by children and their parents. In this Consensus, levels and models of intervention are also enriched by the Italian experience to facilitate a practical approach to the disease.

Coexistence of 2282del4 FLG gene mutation and IL-18 -137G/C gene polymorphism enhances the risk of atopic dermatitis. Postepy Dermatol Alergol 2016; 33:57-62. [PMID: 26985181 PMCID: PMC4793056 DOI: 10.5114/pdia.2015.48050] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/25/2014] [Accepted: 09/10/2014] [Indexed: 01/13/2023] Open
Abstract
Introduction Atopic dermatitis (AD) pathogenesis appears in the context of the correlation between cornified envelope proteins and immunological factors. Aim To estimate the association between FLG R501X and 2282del4 gene mutations, –137 G/C IL-18 and –1112 C/T IL-13 gene polymorphisms and their influence on AD course and the risk in the Polish population. Material and methods One hundred and fifty-two AD patients and 123 healthy volunteers were included into the study. Amplification refractory mutation system – polymerase chain reaction method was used. Results 2282del4 FLG mutation, predominant (p = 0.04) in Polish AD patients, enhanced the risk of AD (OR = 2.35; p = 0.01) and was associated with itch (p = 0.023). GG genotype of IL-18 was prevailing in AD (p < 0.0001), associated with elevated IgE levels (p = 0.00074) and pruritus (p < 0.0001). GG genotype and G-allele in –137 position of IL-18 increased AD risk (OR = 5.4; p = 0.0001, respectively, OR = 5.3; p = 0.000029). –1112 C/T polymorphism of IL-13 was associated with elevated IgE levels (p = 0.00049), pruritus (p = 0.0005), SCORAD score (p = 0.02), concomitant asthma (p = 0.0087) and AD risk (OR = 2.02; p = 0.012). Coexistence of 2282del4 or R501X FLG gene mutation with GG genotype of IL-18 was associated with a 6-fold higher risk of AD (OR = 5.8; p = 0.00013), contrary to combined occurrence of FLG mutations with T-allele in –1112 position of IL-13 gene (OR = 0.12; p = 0.1). Conclusions 2282del4 FLG mutation similarly to GG genotype and G-allele in –137 position of IL-18 gene enhance the risk of AD in the Polish population. Coexistence of FLG mutations with GG genotype of IL-18 may be helpful to estimate chances of AD development.

Abstract
Atopic dermatitis (AD) is a condition frequently encountered in medical practices across the country. More than 60% of children with AD are at risk to develop allergic rhinitis or asthma (the atopic march). Patients with AD have a unique predisposition to colonization or infection by Staphylococcus aureus. Treatments for AD need to rapidly control symptoms of the disease, improve quality of life and prevent exacerbations. Given the chronic and relapsing nature of the disease, therapies need to encourage good compliance and be well tolerated.
