Long-term emollient therapy improves xerosis in children with atopic dermatitis

Topical Treatments in Atopic Dermatitis: An Expansive Review

Atopic dermatitis (AD) is a common inflammatory skin condition found worldwide. It impacts patient quality of life (QoL) and is thought to arise as an inflammatory response to epidermal barrier dysfunction and hypersensitivity. AD can lead to large out-of-pocket costs and increased healthcare expenses over a lifetime. An analysis of all randomized control trials conducted since 1990 on topical therapies for AD were reviewed, including 207 trials in the final analysis. It was found that an average of 226 patients were enrolled over 2.43 arms. Common topical treatments included corticosteroids, calcineurin inhibitors, JAK inhibitors, and phosphodiesterase inhibitors. The most utilized tools to identify treatment efficacy were the EASI, IGA, SCORAD, and PGA. There was a paucity of data on trials that evaluated efficacy, QoL, and cost of treatment simultaneously. This review highlights the need for comprehensive trials that evaluate multiple aspects of treatment, including financial cost and QoL impact, to ensure each patient has the best treatment modality for the management of their AD.

Belgian atopic dermatitis guidelines

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.

S3 Guideline Atopic dermatitis: Part 1 - General aspects, topical and non-drug therapies, special patient groups

This S3 guideline was created based on the European S3 guideline, with special consideration of the medical conditions in the German-speaking region and incorporating additions from the previous German-language version. The interdisciplinary guideline commission consisted of representatives from the German Dermatological Society, the Professional Association of German Dermatologists, the Austrian Society of Dermatology and Venereology, the Swiss Society of Dermatology and Venereology, the German Society for Allergology and Clinical Immunology, the German Society for Pediatric and Adolescent Medicine, the Professional Association of Pediatricians and Adolescent Medicine, the Society for Pediatric Allergology and Environmental Medicine, the German Society for Pediatric Rehabilitation and Prevention, the German Society for Psychosomatic Medicine and Medical Psychotherapy, the German Network for Health Services Research, the German Eczema Association and the German Allergy and Asthma Association. This first part of the guideline focuses on the definition and diagnostic aspects of atopic dermatitis (AD), addressing topical therapy as well as non-pharmacological treatment approaches such as UV therapy, psychoeducational therapy, dietary interventions for AD, allergen immunotherapy for AD, and complementary medicine. This part of the guideline also covers specific aspects of AD in children and adolescents, during pregnancy and lactation, and in the context of family planning. Additionally, it addresses occupational aspects of AD and highlights the perspective of the patients. The second part of the guideline, published separately, addresses the systemic therapy of AD.

How and what adverse events are reported and captured in randomized control trials of emollients in the treatment of eczema?

BACKGROUND

Emollients are universally recommended for atopic dermatitis/eczema ('eczema'), to improve the skin barrier and reduce symptoms. However, our knowledge of the frequency and nature of adverse effects associated with their use is limited.

OBJECTIVES

We sought to determine how well adverse events are reported in randomized controlled trials (RCTs) of emollients for eczema.

METHODS

MEDLINE was searched from inception (1946) to May 2022. Inclusion criteria were RCTs of moisturizers or emollients used as a leave-on treatment (as the intervention or control) in adults or children with eczema. Exclusion criteria were non-RCTs; patients with other diagnoses included; use of emollient as bath additives, soap substitutes or as preventative; and not published in English. References of eligible papers were reviewed for any additional, relevant research. Data were extracted into an Excel spreadsheet and analysed descriptively. An assessment of study quality was carried out using the Joanna Briggs Institute tool for RCTs.

RESULTS

From 369 potential papers, 35 papers (reporting on 34 studies) were included. Most research was conducted in research centres or hospitals (unclear in 34%). In total, 89% reported collecting data on adverse events related to emollient treatment use but the methods used were poorly reported (40% unclear). Four papers used patient questionnaires/diaries. However, it was unclear how and what was collected as only two studies showed the questionnaires used.

CONCLUSIONS

Reporting of adverse events related to emollient use in trials of patients with eczema is poor and inconsistent. Agreement should be reached on how and what adverse events should be collected, to standardize reporting across studies.

Real-World Evidence of an Emollient Device for Atopic and Contact Dermatitis in Pediatric to Adult Patients - Data from a Post-Marketing Surveillance

Purpose

Atopic and contact dermatitis have been attributed to skin barrier abnormalities, immune system dysfunction and inflammation leading to pruritus. As these factors may involve oxidative stress, emollient devices containing antioxidants furfuryl palmitate and tocopherol may help reduce itching and inflammation. In this study, a post-marketing questionnaire was carried out of 40 users of a novel emollient device containing furfuryl palmitate and tocopherol (Relizema™ cream), who purchased it from a pharmacy or health-care professional to ascertain the emollient device's action on itching, flushing and moisturizing.

Patients and Methods

The post-marketing questionnaire, administered by trained pharmacy and health-care staff, collected data on age; diagnosis; number of times per day and for how many days the emollient device was applied; whether the product helped alleviate itching and flushing, and in what time frame if so; and how their skin felt after using the emollient.

Results

Most patients had atopic dermatitis (n = 25) or irritant contact dermatitis (n = 10); most were aged ≥19 years (n = 20) or between 3 and 12 years (n = 12). Most used the emollient device twice a day (n = 26) or more (n = 11) with 27 using it for ≤30 days. Patients predominantly reported that the emollient device "significantly improved" itching (n = 34) and flushing (n = 31) with a response being noted within 1 day (n = 17) or 1 week (n = 22). All users felt the product "protected and moisturized" their skin, the product texture was "pleasant" to "excellent" and the "non-fragrance" smell was "acceptable" to "excellent".

Conclusion

Use of a novel emollient device containing ingredients aimed at managing atopic or contact dermatitis, including furfuryl palmitate and tocopherol, led to rapid improvements in itching and flushing. The emollient device was acceptable to the users.

European guideline (EuroGuiDerm) on atopic eczema - part II: non-systemic treatments and treatment recommendations for special AE patient populations

The evidence- and consensus-based guideline on atopic eczema was developed in accordance with the EuroGuiDerm Guideline and Consensus Statement Development Manual. Four consensus conferences were held between December 2020 and July 2021. Twenty-nine experts (including clinicians and patient representatives) from 12 European countries participated. This second part of the guideline includes recommendations and detailed information on basic therapy with emollients and moisturizers, topical anti-inflammatory treatment, antimicrobial and antipruritic treatment and UV phototherapy. Furthermore, this part of the guideline covers techniques for avoiding provocation factors, as well as dietary interventions, immunotherapy, complementary medicine and educational interventions for patients with atopic eczema and deals with occupational and psychodermatological aspects of the disease. It also contains guidance on treatment for paediatric and adolescent patients and pregnant or breastfeeding women, as well as considerations for patients who want to have a child. A chapter on the patient perspective is also provided. The first part of the guideline, published separately, contains recommendations and guidance on systemic treatment with conventional immunosuppressive drugs, biologics and janus kinase (JAK) inhibitors, as well as information on the scope and purpose of the guideline, and a section on guideline methodology.

New and Upcoming Topical Treatments for Atopic Dermatitis: A Review of the Literature

Atopic dermatitis (AD) is a chronic inflammatory dermatosis with periods of exacerbation and remissions. AD is characterized by intense, persistent pruritus and heterogeneity in clinical symptomatology and severity. Therapeutic goals include the amelioration of cutaneous eruptions, diminishing relapses and eventually the disease burden. To date, topical corticosteroids (TCS) and calcineurin inhibitors (TCI) have yet been deemed the mainstay of topical treatments in AD management. Nevertheless, despite their indisputable efficiency, TCS and TCI are not indicated for continuous long-term use given their safety profile. While research in AD has concentrated predominantly on systemic therapies, more than 30 novel topical compounds are under development. The existing data appear encouraging, with some regimens that are already FDA-approved (ruxolitinib was the most recent in September 2021) and several pharmaceutical pipeline products for mild-to-moderate AD that are in an advanced stage of development, such as tapinarof, difamilast and roflumilast. Larger, long-term studies are still required to evaluate the efficacy and safety of these novel compounds in the long run and weigh their advantages over present treatments. In this review, we aim to provide an overview of the latest knowledge about AD topical treatments, echoing upcoming research trends.

English Version of Clinical Practice Guidelines for the Management of Atopic Dermatitis 2021

This is the English version of the Clinical Practice Guidelines for the Management of Atopic Dermatitis 2021. Atopic dermatitis (AD) is a disease characterized by relapsing eczema with pruritus as a primary lesion. In Japan, from the perspective of evidence-based medicine, the current strategies for the treatment of AD consist of three primary measures: (i) use of topical corticosteroids, tacrolimus ointment, and delgocitinib ointment as the main treatment of the inflammation; (ii) topical application of emollients to treat the cutaneous barrier dysfunction; and (iii) avoidance of apparent exacerbating factors, psychological counseling, and advice about daily life. In the present revised guidelines, descriptions of three new drugs, namely, dupilumab, delgocitinib, and baricitinib, have been added. The guidelines present recommendations to review clinical research articles, evaluate the balance between the advantages and disadvantages of medical activities, and optimize medical activity-related patient outcomes with respect to several important points requiring decision-making in clinical practice.

English version of guidelines for the management of asteatosis 2021 in Japan

This is the English version of guidelines for the management of asteatosis 2021 in Japan. Asteatosis is a synonym of xerosis found in a wide range of diseases that induce dry skin through impaired functions of either water retention of the stratum corneum or skin covering with acid mantle. Patients with asteatosis may be accompanied by pruritus. Moisturizers are the first-line treatment for asteatosis and their adequate use must be recommended. The main purpose of the present guidelines is to define skin symptoms requiring treatment with moisturizers for medical use in patients with asteatosis. If the deterioration of marked scaling or scratch marks is predicted, therapeutic intervention with moisturizers for medical use should be considered even in the absence of pruritus. Regarding six important points requiring decision-making in clinical practice (clinical questions), we evaluated the balance between the benefits and harm of medical interventions in reference to previous reports of clinical research, and presented the recommendation grades and evidence levels to optimize the patient outcome by medical interventions.

Sensitivity of clinician-assessed efficacy outcome measurement instruments in trials of topical therapies for atopic dermatitis: a systematic review and meta-analysis

The rising prevalence of atopic dermatitis (AD) in developing countries and its substantial socioeconomic impact have furthered research over the last two decades giving way to advances in its aetiopathogenesis and treatment. Topical therapies targeting newly identified AD signalling pathways are being developed. Numerous clinician-assessed disease severity outcome measurement instruments (OMIs) are available to evaluate the efficacy of investigational treatments in proof-of-concept (POC) trials for AD. However, little is known about the comparative sensitivity of these efficacy OMIs. We performed a systematic review and meta-analysis to compare the sensitivity of different OMIs in controlled trials of topical therapies for AD published between January 1, 2000 and April 7, 2020. Treatment effect size of OMIs reported at Week 4 was calculated with 95% Confidence Interval (CI). The sensitivity of OMIs was compared by pooling the standardized difference between means (Cohen's d and Cohen's h) for any two OMI-parameter combinations that were reported in ≥3 studies identified in our systematic review. Assessed parameters were difference between active and vehicle at Week 4 and change from baseline [CFB] and percentage change from baseline [%CFB] at Week 4. We identified a total of 15 studies with 3313 subjects examining 14 different OMIs were included in this quantitative meta-analysis. Continuous OMIs had a significantly higher treatment effect size vs. dichotomous OMIs (P = 0.006). Comparisons of Eczema Area and Severity Index (EASI), Investigator's Global Assessment (IGA), body surface area (BSA) and SCORing Atopic Dermatitis (SCORAD) for available parameters were performed and generally had a similar sensitivity, with BSA showing smaller overall effect size estimates. In conclusion, continuous OMIs used in topical clinical trials for AD had significantly higher treatment effect sizes when compared to dichotomous OMIs. Continuous OMIs could provide more power for POC trials with a small sample size in atopic dermatitis with topical therapies.

Efficacy of moisturizers in paediatric atopic dermatitis: A systematic review and meta-analysis of randomised controlled trials

BACKGROUND

Topical moisturizer is recommended for atopic dermatitis.

AIMS

The aim of the study was to investigate the knowledge gap regarding the efficacy of moisturizer in young patients.

METHODS

A systematic review and meta-analysis were conducted on randomised controlled trials comparing participant's ≤15 years with atopic dermatitis, receiving either topical moisturizer or no moisturizer treatment. Certainty of evidence was assessed using the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) framework.

RESULTS

Six trials were included (intervention n= 436; control n= 312). Moisturizer use extended time to flare by 13.52 days (95% confidence interval 0.05-26.99, I2 88%). Greater reduction in risk of relapse was observed during the first month of latency (pooled risk ratio 0.47, 95% confidence interval 0.31-0.72, I2 28%) compared to the second and third months (pooled risk ratio 0.65, 95% confidence interval 0.47-0.91, I2 35% and pooled risk ratio 0.63, 95% confidence interval 0.47-0.83, I2 33%, respectively).Treated patients were 2.68 times more likely to experience a three-six months remission (95% confidence interval1.18-6.09, I2 56%). Moisturizer minimally improved disease severity and quality of life.

LIMITATIONS

There is a dire need to conduct randomised controlled trialswith more robust and standardised designs.

CONCLUSION

Moisturizer benefits young patients with atopic dermatitis. However, more research is needed to better estimate its efficacy.

Topical corticosteroid vehicle composition and implications for clinical practice

This narrative review highlights the therapeutic significance of topical corticosteroid (TCS) vehicles and provides subsequent guidance to improve clinical and research outcomes. A greater understanding of the relationship between the topical vehicle, corticosteroid and skin is needed to ensure safer, more effective treatment for patients. Topical vehicles are not inert and can affect TCS bioavailability, due to the ability of their composition to positively or negatively influence skin status and change the physiochemical characteristics of an inherent corticosteroid. However, this principle is not commonly understood, and has contributed to inconsistencies in potency classification systems. This review provides an insight into the research methods and standardization needed to determine TCS product bioavailability. It identifies formulation components responsible for vehicle composition that underpin the quality, stability, compounding and functionalities of vehicle ingredients. This helps to contextualize how topical vehicles can be responsible for clinically significant effects, and how their composition gives products unique properties. In turn, this facilitates a more in-depth understanding of which resources offer information to inform the best selection of TCS products and why products should be prescribed by brand or manufacturer. This review will better equip clinicians and formulary teams to appraise products. It will also inform prescribing of Specials and why products should not be manipulated. The recommendations, accompanied by patient perspectives on using TCS products, assist clinical decision-making. They also identify the need for research into concomitant application of TCS products with other topical therapies.

Evaluation of factors that may affect disease development and severity in childhood atopic dermatitis

BACKGROUND

Atopic dermatitis is a chronic, relapsing, inflammatory disease. Data concerning the role of perinatal conditions in the development of the disease are few and inconsistent. The purpose of this study was to investigate the effects of skin care on the severity of the disease, also to evaluate the relations of perinatal conditions with disease development and severity.

METHODS

Seventy-five patients with atopic dermatitis aged 2-10 years, their parents and 65 healthy age-compatible volunteers and their parents were included in the study. The Scoring Atopic Dermatitis (SCORAD) score was used to assess the severity of the disease.

RESULTS

Emollient use (regular/irregular) was higher in patients with severe disease compared to those with mild and moderate disease, but no significant difference was determined in regular use rates (P=0.029, and P=0.504, respectively). Topical corticosteroid use and sleep disturbance rates in the previous three months in the subjects regularly using emollients were low (P=0.032, and P=0.005, respectively). The incidence of severe disease was higher in the patients born in the winter (P=0.033). Severe disease rates were significantly high in the subjects in the patient group with advanced maternal age, a history of cesarean delivery and incubator use (P=0.017, P=0.046, and P=0.025, respectively).

CONCLUSIONS

Low topical corticosteroid requirement and sleep disturbance rates in the subjects regularly using moisturizers emphasize the importance of emollient use in treatment. The association of cesarean delivery, history of incubator, and birth in winter with severe disease suggests that disease severity is related to less exposure to environmental allergens in the hygiene hypothesis.

Atopic dermatitis. Interdisciplinary diagnostic and therapeutic recommendations of the Polish Dermatological Society, Polish Society of Allergology, Polish Pediatric Society and Polish Society of Family Medicine. Part I. Prophylaxis, topical treatment and phototherapy

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.

Pruritus in pediatric patients with atopic dermatitis: a multidisciplinary approach - summary document from an Italian expert group

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.

Clinical use of Capilen, a liposomal cream based on fresh plant extracts enriched with omega fatty acids

The skin is the largest organ in the human body; beyond its regulatory and sensory roles, it is meant to protect and act like a barrier against foreign matter. Products intended to restore the skin health should reintegrate the structure of the stratum corneum in which the corneocytes are surrounded by the intercellular lipid lamellae that maintain both corneum integrity and skin permeability barrier. Capilen is a specific liposomal formulation based on a technology through which highly concentrated fresh plant extracts are conveyed into a jelly-like liposomal vehicle and combined with plant-derived omega-3, -6, -7, and -9 fatty acids, phospholipids, and precursors of ceramides. Its components have been widely investigated and produced clinical benefits in atopic dermatitis, bedsores, scars, inflammatory lesions of the skin, and generally whenever signs of xerosis cutis were present. Liposomes contribute to restore the surface lipid layer of the skin and to deliver substances in the activity site. This liposomal cream was proven to limit and delay the occurrence of radiodermatitis in breast cancer patients, and as an add-on provided complete healing of bedsore lesions in geriatric subjects.

Glycerol 85% efficacy on atopic skin and its microbiome: a randomized controlled trial with clinical and bacteriological evaluation

Background: Treating atopic dermatitis (AD) is still a challenge. The staphylococcal skin load is known to aggravate AD. Narrow band ultraviolet B (NB-UVB) and glycerol in low concentration (20-40%) are established therapies for AD. NB-UVB has proven antimicrobial actions, while high concentration glycerol (85-100%) showed similar effects in vitro but has not been clinically tested.Objective: To evaluate the efficacy and tolerability of concentrated glycerol 85% compared to NB-UVB in patients with AD, as assessed by clinical improvement and reduction of staphylococcal colonization of the skin.Methods: 30 patients with mild to moderate AD were randomized into either NB-UVB or glycerol 85% group. Patients were treated for one month and followed for an additional month. Swabs were taken from the skin and nose to be cultured on mannitol-salt agar for Staphylococci and quantified to determine Colony Forming Units.Results: Both groups showed statistically insignificant microbial changes and statistically significant clinical improvement after treatment. The results were comparable between both groups.Conclusions: Concentrated glycerol 85% is a cheap effective readily accessible alternative for phototherapy in patients with mild-moderate AD who cannot access the facility. Reduction of staphylococcal skin load seems to be involved, but its role is minimal.

Clinical practice guidelines for the management of atopic dermatitis 2018

Atopic dermatitis (AD) is a disease characterized by relapsing eczema with pruritus as a primary lesion. The current strategies to treat AD in Japan from the perspective of evidence-based medicine consist of three primary measures: (i) the use of topical corticosteroids and tacrolimus ointment as the main treatment for the inflammation; (ii) topical application of emollients to treat the cutaneous barrier dysfunction; and (iii) avoidance of apparent exacerbating factors, psychological counseling and advice about daily life. The guidelines present recommendations to review clinical research articles, evaluate the balance between the advantages and disadvantages of medical activities, and optimize medical activity-related patient outcomes with respect to several important points requiring decision-making in clinical practice.

The improvement of infantile atopic dermatitis during the maintenance period: A multicenter, randomized, parallel controlled clinical study of emollients in Prinsepia utilis Royle

In order to investigate the effect of daily emollient treatment on infantile atopic dermatitis (AD) during the maintenance period, a total of 309 children younger than 2 years with moderate AD (155 and 154 in the treatment and control groups, respectively) were enrolled in this multicenter, randomized, parallel controlled clinical trial. Subjects were topically treated with desonide cream and emollients in Prinsepia utilis Royle for 2-4 weeks before entering the maintenance period and then differentially treated with either emollients for treatment or none for control. The cumulative maintenance rate, time to flare and improvement of eczema area and severity index (EASI) and infant's dermatitis quality of life index (IDQOL) were evaluated. Results showed that the cumulative maintenance rate of the treatment group (60.5%, 95% CI 50.0-69.4%) was significantly higher than that of the control group (23.5%, 95% CI 15.2-33.0%) (p < .001). The median time to flare in the treatment group was 90 days (interquartile range, IQR 28-90), which was significantly longer than that in the control group (28 days [IQR 18-67]) (p < .001). At Week 4 in the maintenance period, the EASI and IDQOL scores of the treatment group were lower than those of the control group. In conclusion, the application of emollients during the maintenance period of infantile AD can significantly reduce the risk of AD flares, prolong the time to flare and improve the clinical symptoms.

Adverse Events from Emollient Use in Eczema: A Restricted Review of Published Data

Atopic dermatitis/eczema is a chronic inflammatory skin condition, and emollients are the first-line treatment. Despite their widespread use, there is uncertainty about the frequency and type of adverse events associated with different emollients. We conducted a restricted review of published data on adverse events associated with emollient use in eczema. Medline (Ovid) was searched from inception (1946) to June 2018. All types of studies, with the exception of reviews, were included. Eligibility was assessed using a two-stage screening process against inclusion and exclusion criteria. References of all included papers were screened for any additional eligible papers. Data were subsequently extracted from all eligible publications. A limited body of data were found in the published data: 24 papers reported on adverse events with 29 different emollients (3 containing urea, 5 containing ceramide, 4 containing glycerol, 4 were herbal and 13 contained "other" ingredients). Interpretation of the results and comparison of the emollients were difficult due to poor reporting and missing data. Many publications contained no data at all on adverse events, and no study reported serious treatment-related adverse events for any emollient. The proportion of participants in the studies experiencing treatment-related adverse events varied between 2 and 59%. The most common adverse events were skin related and often mild. The range of participants experiencing non-treatment-related adverse events varied between 4 and 43%. From this restricted review, clinicians and patients can be reassured that the emollients studied appear to be generally safe to use. Better studies and reporting of adverse events associated with emollients in common use are needed.

Consensus-based European guidelines for treatment of atopic eczema (atopic dermatitis) in adults and children: part I

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.

A Systematic Scoping Literature Review of Publications Supporting Treatment Guidelines for Pediatric Atopic Dermatitis in Contrast to Clinical Practice Patterns

INTRODUCTION

Treatment guidelines endorse a variety of strategies for atopic dermatitis (AD) which may vary from published data and clinical practice patterns. The objective of this review was to quantify the volume of available medical literature supporting pediatric AD treatments and compare these patterns to those recommended by published guidelines and/or clinical practice patterns.

METHODS

Searches of Embase (2005-2016) and abstracts from selected meetings (2014-2016) related to AD treatment in patients younger than 17 years of age yielded references that were assessed by study design, primary treatment, age groups, and AD severity.

RESULTS

Published literature partially supports clinical guidelines, with emollients and topical medications being the most investigated. There were disproportionately more publications for topical calcineurin inhibitors (TCI) compared with topical corticosteroids (TCS); however, the search interval may have biased the results toward treatments approved near the beginning of the time frame. In contrast, publications documenting clinical practice patterns reflect greater use of emollients and TCS (over TCI), as well as systemic corticosteroids. Data is relatively limited for long-term and combination treatment, treatment of severe AD, and patients younger than 2 years of age, and completely lacking for systemic corticosteroids.

CONCLUSION

This scoping review demonstrates that available medical literature largely supports published guidelines for topical therapy; however, clinical practice patterns are less aligned. There is a lack of data for older, more frequently used generic treatments, including oral antihistamines, oral antibiotics, and systemic corticosteroids. Overall, literature is lacking for long-term treatment, treatment for patients younger than 2 years of age, and for systemic treatment for severe disease.

Efficacy and Tolerability of a Medical Device Repairing Emollient Cream Associated with a Topical Corticosteroid in Adults with Atopic Dermatitis: An Open-label, Intra-individual Randomized Controlled Study

Introduction

Medical device repairing emollient creams (MDRECs) are designed to repair and protect the skin barrier. In this study, we examined the added clinical benefit and tolerability of a MDREC when used in association with a moderately potent topical corticosteroid (TCS) for adults with atopic dermatitis (AD).

Methods

This was an intra-individual randomized controlled trial in adults with moderate to severe AD (EudraCT no. 2014-002,194-10). Symmetrical lesions on each arm of the subjects were randomized to treatment for 10 days with twice-daily TCS (desonide) cream alone or with combined TCS + MDREC. Subjects were then included in a following 2-week maintenance phase if the AD on at least one test area had sufficiently improved so that the treatment was no longer needed. During the maintenance phase, treatment with the TCS cream was stopped, but twice-daily application of the MDREC was continued on the same test area previously assigned to receive it. The primary outcome measure was the change in local Scoring Atopic Dermatitis (SCORAD) index between day 1 and 3 based on investigators’ assessment. Secondary measures of lesion severity included changes in the local patient-oriented SCORAD index, pruritus intensity according to subjects’ assessments, and global assessments by subjects and investigators.

Results

The study included 54 subjects. The change in investigator-observed local SCORAD index between day 1 and 3 was − 14.4% with TCS alone and − 24.5% for TCS + MDREC (p = 0.0005). Between baseline and the end of the treatment phase, all secondary measures of lesion severity decreased more with the combined TCS + MDREC treatment than with the TCS cream alone. The MDREC also reduced the relapse of AD lesions during the maintenance phase. Tolerability was very good, and the product was well accepted by subjects.

Conclusion

These results support using the MDREC in association with TCS during AD flares and as a maintenance therapy after treatment with TCS has stopped.

Emollients and moisturizers for eczema: abridged Cochrane systematic review including GRADE assessments

Eczema is a chronic inflammatory skin disorder with considerable impact on quality of life. Emollients or moisturizers are widely recommended, but are these effective and safe? We searched for randomized controlled trials (RCTs) in the Cochrane Skin Group Specialised Skin Register, CENTRAL in The Cochrane Library, MEDLINE, Embase, LILACS, the GREAT database and five trial registers to December 2015. We included 77 RCTs with 6603 participants. Seven studies (9%) were at low risk of bias, 34 (44%) had unclear risk and 36 (47%) were at high risk. The quality of the evidence was mainly low or moderate for the prespecified outcomes. The most important comparison, 'moisturizer vs. no moisturizer', showed improved Scoring Atopic Dermatitis values in the moisturizer group compared with no moisturizer [mean difference -2·42, 95% confidence interval (CI) -4·55 to -0·28], but did not meet the minimal important difference of 8·7. Fewer flares were seen (risk ratio 0·40, 95% CI 0·23-0·70) and the rate of flares was reduced (hazard ratio 3·74, 95% CI 1·86-7·50). The groups applying moisturizer used less topical corticosteroids over 6-8 weeks (mean difference -9·30 g, 95% CI 15·3 to -3·27). Glycyrrhetinic acid-, urea- and glycerol-containing creams worked better than their controls (vehicle, placebo or no moisturizer) according to both participants and physicians. More flares were reported with moisturizer alone than when combined with twice-weekly fluticasone propionate (risk ratio 2·17, 95% CI 1·55-3·11). Adding moisturizers to topical anti-inflammatory treatment was more effective than anti-inflammatory treatment alone and resulted in fewer flares.

Long-term treatment of cutaneous manifestations of tuberous sclerosis complex with topical 1% sirolimus cream: A prospective study of 25 patients

BACKGROUND

Data on long-term topical sirolimus treatment of the cutaneous manifestations of tuberous sclerosis complex are rare.

OBJECTIVE

To evaluate the long-term benefit and tolerance of topical 1% sirolimus in tuberous sclerosis complex.

METHODS

In this 18-month prospective single-center study, 1% sirolimus cream was applied daily to facial angiofibromas (FAs), fibrous cephalic plaques (FCPs), shagreen patches, hypomelanotic macules, and ungual fibromas. After complete clearance (CC) of FAs, we evaluated a maintenance protocol of 3 applications weekly.

RESULTS

Twenty-five patients were enrolled. Fifty percent obtained CC of FAs within 9 months. Of 7 patients with CC (58%) who were following the maintenance protocol, 6 relapsed within 7 months and 1 was still responding at 1 year. Of 16 patients with FCPs, 7 (44%) remained stable at 12 months and 9 (56%) improved after 3 to 9 months of treatment. Only 1 of 5 patients treated for shagreen patches showed improvement at 12 months. Treatment was well tolerated with no serious adverse events.

LIMITATIONS

The small number of patients was a limitation.

CONCLUSIONS

Topical 1% sirolimus applied daily produced positive responses in treatment of FAs, FCPs, and facial hypomelanotic macules and was well tolerated. A 3-times-weekly maintenance protocol did not prevent FA relapses.

Prevention of Flares in Children with Atopic Dermatitis with Regular Use of an Emollient Containing Glycerol and Paraffin: A Randomized Controlled Study

BACKGROUND/OBJECTIVES

Emollients are part of the standard treatment for atopic dermatitis (AD), although there is limited evidence that regular use of emollients as management therapy reduces the frequency of flares and corticosteroid consumption. The objective of this study was to evaluate the benefit of emollient use in the management of mild to moderate AD in children by assessing the ability of two different emollients (particularly V0034CR) to prevent flares and to reduce the use of corticosteroids.

METHODS

In this randomized, open-label study, patients with a current flare were treated with a potent topical corticosteroid. After flare resolution, patients were centrally randomized to V0034CR emollient, reference emollient, or no emollient (1:1:1 ratio) for 12 weeks. New flares were medically assessed before being treated with a moderately potent corticosteroid.

RESULTS

A total of 335 children 2 to 6 years of age were randomized. At 12 weeks, the percentage of patients with one or more flares was statistically significantly lower with V0034CR (35.1%) than without emollient (67.6%; p < 0.001). Fewer patients treated with V0034CR required any corticosteroids or immunosuppressants (23.6%) than patients with no emollient (43.3%) at 12 weeks. The difference was significant at all time points (p = 0.002). Patients treated with emollients had a longer time to first flare, fewer flares, higher complete remission rates, less corticosteroid consumption, lower Investigator Global Assessment scores, and lower Scoring Atopic Dermatitis scores than those who were not. V0034CR was well tolerated, with no specific safety concerns.

CONCLUSION

Regular emollient use in children with mild to moderate AD reduces flares and corticosteroid consumption.

Selected active naturals for atopic dermatitis: Atopic Dermatitis Part 1

The desire for naturally derived agents is a growing trend for patients, physicians, and pharmaceutical companies. Studies indicate that complementary and alternative medicine is often used by patients and parents of children with atopic dermatitis, not necessarily with beneficial results. A half-dozen natural agents (ie, topical agents: coconut oil, colloidal oatmeal, sunflower oil, mustard oil, glycerin, and oral Chinese herbal therapy) are discussed because they have become popular for their expected activity in the therapy of atopic dermatitis. A critical review of the published literature on these agents is presented with specific focus on potential such side effects as hepatotoxicity with Chinese herbals.

Methylprednisolone aceponate for atopic dermatitis

BACKGROUND

The 4th generation topical corticosteroids (TCS) have demonstrated a most favorablerisk-benefit ratio. Methylprednisolone aceponate (MPA) is a non-halogenated corticosteroid with a methyl group at C6, which confers higher intrinsic activity. MPA is included in the group of potent TCS (category III/IV).

METHODS

A literature review is carried out of the clinical efficacy, pharmacokinetics, and adverse effects of MPA, especially for the treatment of atopic dermatitis (AD).

RESULTS

Several clinical studies support the use of MPA in infants and children, with minimal local or systemic adverse effects reported. The pharmacokinetic profile and the low rate of adverse effects of MPA are most suitable for the treatment of atopic dermatitis (AD), a chronic disease with frequent flaring that can involve extensive areas of the skin.

CONCLUSIONS

Most patients with AD can be easily brought into control with the use of only TCS. Achieving a complete healing of eczema is key in AD, and once the skin is clinically healthy, emollients can be used according to the physician and patient preferences. Physicians should be trained in the recognition of early or subtle manifestations of active eczema that are most suitably treated with topical TCS to achieve a most rapid and satisfactory control of the disease. If the whole area with eczema is not treated, active eczema will remain and treatment will be ineffective. Insufficient use of TCS will lead to inefficiency and frustration.

Regression of cutaneous xerosis with emollient treatment in sub-Saharan African patients

Emollients have proven effective in improving cutaneous xerosis in various populations; however, no clinical data are available for African patients. The observational study "Xerafrica" was conducted by dermatologists in seven sub-Saharan countries to assess the evolution of xerosis after an 8-week treatment with an emollient. Patients were children above 3 years or adults. Secondary objectives were to assess pruritus, improvement in symptoms, quality of life, satisfaction, and tolerance. An analysis of 185 patients was made. After 8 weeks of emollient treatment, the relative reduction of the "Scaling Roughness Redness Cracks" (SRRC) score was -83.9% and -80.4% in children and adults, respectively. The effect was significantly stronger when topical steroids were co-prescribed with the emollient and in patients with co-dermatosis. To a lesser extent, the effect of emollient was also observed at week 4. Similarly, pruritus and quality of life strongly improved during follow-up. Skin lesions improved in almost all patients, with a high level of satisfaction noted by both dermatologists and patients. The "Xerafrica" study addressed, for the first time, the treatment of xerosis by emollients in an African population. In this specific context, the emollient markedly reduced xerosis as soon as 4 weeks and resolved it almost totally by 8 weeks. The study confirms, under real-life conditions, the efficacy and tolerability of an emollient in improving xerosis.

Emollients and moisturisers for eczema

BACKGROUND

Eczema is a chronic skin disease characterised by dry skin, intense itching, inflammatory skin lesions, and a considerable impact on quality of life. Moisturisation is an integral part of treatment, but it is unclear if moisturisers are effective.

OBJECTIVES

To assess the effects of moisturisers for eczema.

SEARCH METHODS

We searched the following databases to December 2015: Cochrane Skin Specialised Register, CENTRAL, MEDLINE, Embase, LILACS, the GREAT database. We searched five trials registers and checked references of included and excluded studies for further relevant trials.

SELECTION CRITERIA

Randomised controlled trials in people with eczema.

DATA COLLECTION AND ANALYSIS

We used standard Cochrane methodological procedures.

MAIN RESULTS

We included 77 studies (6603 participants, mean age: 18.6 years, mean duration: 6.7 weeks). We assessed 36 studies as at a high risk of bias, 34 at unclear risk, and seven at low risk. Twenty-four studies assessed our primary outcome 'participant-assessed disease severity', 13 assessed 'satisfaction', and 41 assessed 'adverse events'. Secondary outcomes included investigator-assessed disease severity (addressed in 65 studies), skin barrier function (29), flare prevention (16), quality of life (10), and corticosteroid use (eight). Adverse events reporting was limited (smarting, stinging, pruritus, erythema, folliculitis).Six studies evaluated moisturiser versus no moisturiser. 'Participant-assessed disease severity' and 'satisfaction' were not assessed. Moisturiser use yielded lower SCORAD than no moisturiser (three studies, 276 participants, mean difference (MD) -2.42, 95% confidence interval (CI) -4.55 to -0.28), but the minimal important difference (MID) (8.7) was unmet. There were fewer flares with moisturisers (two studies, 87 participants, RR 0.40, 95% CI 0.23 to 0.70), time to flare was prolonged (median: 180 versus 30 days), and less topical corticosteroids were needed (two studies, 222 participants, MD -9.30 g, 95% CI -15.3 to -3.27). There was no statistically significant difference in adverse events (one study, 173 participants, risk ratio (RR) 15.34, 95% CI 0.90 to 261.64). Evidence for these outcomes was low quality.With Atopiclair (three studies), 174/232 participants experienced improvement in participant-assessed disease severity versus 27/158 allocated to vehicle (RR 4.51, 95% CI 2.19 to 9.29). Atopiclair decreased itching (four studies, 396 participants, MD -2.65, 95% CI -4.21 to -1.09) and achieved more frequent satisfaction (two studies, 248 participants, RR 2.14, 95% CI 1.58 to 2.89), fewer flares (three studies, 397 participants, RR 0.18, 95% CI 0.11 to 0.31), and lower EASI (four studies, 426 participants, MD -4.0, 95% CI -5.42 to -2.57), but MID (6.6) was unmet. The number of participants reporting adverse events was not statistically different (four studies, 430 participants, RR 1.03, 95% CI 0.79 to 1.33). Evidence for these outcomes was moderate quality.Participants reported skin improvement more frequently with urea-containing cream than placebo (one study, 129 participants, RR 1.28, 95% CI 1.06 to 1.53; low-quality evidence), with equal satisfaction between the two groups (one study, 38 participants, low-quality evidence). Urea-containing cream improved dryness (investigator-assessed) more frequently (one study, 128 participants, RR 1.40, 95% CI 1.14 to 1.71; moderate-quality evidence) with fewer flares (one study, 44 participants, RR 0.47, 95% CI 0.24 to 0.92; low-quality evidence), but more participants in this group reported adverse events (one study, 129 participants, RR 1.65, 95% CI 1.16 to 2.34; moderate-quality evidence).Three studies assessed glycerol-containing moisturiser versus vehicle or placebo. More participants in the glycerol group noticed skin improvement (one study, 134 participants, RR 1.22, 95% CI 1.01 to 1.48; moderate-quality evidence), and this group saw improved investigator-assessed SCORAD (one study, 249 participants, MD -2.20, 95% CI -3.44 to -0.96; high-quality evidence), but MID was unmet. Participant satisfaction was not addressed. The number of participants reporting adverse events was not statistically significant (two studies, 385 participants, RR 0.90, 95% CI 0.68 to 1.19; moderate-quality evidence).Four studies investigated oat-containing moisturisers versus no treatment or vehicle. No significant differences between groups were reported for participant-assessed disease severity (one study, 50 participants, RR 1.11, 95% CI 0.84 to 1.46; low-quality evidence), satisfaction (one study, 50 participants, RR 1.06, 95% CI 0.74 to 1.52; very low-quality evidence), and investigator-assessed disease severity (three studies, 272 participants, standardised mean difference (SMD) -0.23, 95% CI -0.66 to 0.21; low-quality evidence). In the oat group, there were fewer flares (one study, 43 participants, RR 0.31, 95% CI 0.12 to 0.7; low-quality evidence) and less topical corticosteroids needed (two studies, 222 participants, MD -9.30g, 95% CI 15.3 to -3.27; low-quality evidence), but more adverse events were reported (one study, 173 participants; Peto odds ratio (OR) 7.26, 95% CI 1.76 to 29.92; low-quality evidence).All moisturisers above were compared to placebo, vehicle, or no moisturiser. Participants considered moisturisers more effective in reducing eczema (five studies, 572 participants, RR 2.46, 95% CI 1.16 to 5.23; low-quality evidence) and itch (seven studies, 749 participants, SMD -1.10, 95% CI -1.83 to -0.38) than control. Participants in both treatment arms reported comparable satisfaction (three studies, 296 participants, RR 1.35, 95% CI 0.77 to 2.26; low-quality evidence). Moisturisers led to lower investigator-assessed disease severity (12 studies, 1281 participants, SMD -1.04, 95% CI -1.57 to -0.51; high-quality evidence) and fewer flares (six studies, 607 participants, RR 0.33, 95% CI 0.17 to 0.62; moderate-quality evidence), but there was no difference in adverse events (10 studies, 1275 participants, RR 1.03, 95% CI 0.82 to 1.30; moderate-quality evidence).Topical active treatment combined with moisturiser was more effective than active treatment alone in reducing investigator-assessed disease severity (three studies, 192 participants, SMD -0.87, 95% CI -1.17 to -0.57; moderate-quality evidence) and flares (one study, 105 participants, RR 0.43, 95% CI 0.20 to 0.93), and was preferred by participants (both low-quality evidence). There was no statistically significant difference in number of adverse events (one study, 125 participants, RR 0.39, 95% CI 0.13 to 1.19; very low-quality evidence). Participant-assessed disease severity was not addressed.

AUTHORS' CONCLUSIONS

Most moisturisers showed some beneficial effects, producing better results when used with active treatment, prolonging time to flare, and reducing the number of flares and amount of topical corticosteroids needed to achieve similar reductions in eczema severity. We did not find reliable evidence that one moisturiser is better than another.

Fragility of epidermis in newborns, children and adolescents

Within their first days of life, newborns' skin undergoes various adaptation processes needed to accommodate the transition from the wet uterine environment to the dry atmosphere. The skin of newborns and infants is considered as a physiological fragile skin, a skin with lower resistance to aggressions. Fragile skin is divided into four categories up to its origin: physiological fragile skin (age, location), pathological fragile skin (acute and chronic), circumstantial fragile skin (due to environmental extrinsic factors or intrinsic factors such as stress) and iatrogenic fragile skin. Extensive research of the past 10 years have proven evidence that at birth albeit showing a nearly perfect appearance, newborn skin is structurally and functionally immature compared to adult skin undergoing a physiological maturation process after birth at least throughout the first year of life. This article is an overview of all known data about fragility of epidermis in 'fragile populations': newborns, children and adolescents. It includes the recent pathological, pathophysiological and clinical data about fragility of epidermis in various dermatological diseases, such as atopic dermatitis, acne, rosacea, contact dermatitis, irritative dermatitis and focus on UV protection.

Children with Dry Skin and Atopic Predisposition: Outcome Measurement with Validated Scores for Atopic Dermatitis

BACKGROUND

Dry skin is a common skin condition in childhood. Few studies exist investigating the influence of daily skin care on dry skin in infants at risk of developing atopic dermatitis (AD). We aimed to assess the effect of skin care on dry skin in this special cohort using validated scores for AD and analysis of skin microtopography.

METHODS

43 children were randomized to group 1 (G1) and group 2 (G2) and 22 infants to group 3 (G3). During 16 weeks, G1 and G3 applied daily a plant-based emollient and G2 a petrolatum-based emollient. The core outcome was assessed by Severity Scoring of Atopic Dermatitis (SCORAD) and Patient-Oriented SCORing Atopic Dermatitis (PO-SCORAD). The influence on the parents' life was evaluated by a questionnaire and microtopography by Visioscan® VC 98.

RESULTS

The SCORAD index declined significantly until week (W) 16 in all groups (p ≤ 0.041). The sleeplessness score analyzed by PO-SCORAD was highly reduced after W12 in G1 and after W16 in G2 (p ≤ 0.030). The influence on the parents' anxiety was reduced in G3 at W12 and W16 (p = 0.016). The Visioscan parameter scaliness strongly diminished at W4 (p ≤ 0.049) and W16 (p ≤ 0.013) in all groups.

CONCLUSIONS

This trial demonstrates improved skin conditions and sleep following daily emollient application in infants and children having dry skin and being at risk of AD. Especially parents of infants showed a reduced fear that their children might develop AD. Further studies are required to investigate the preventive effect of daily emollient therapy in this special cohort evaluating the outcome measures used in this trial.

The adaptive immune system in atopic dermatitis and implications on therapy

In atopic dermatitis (AD), the skin inflammation is believed to occur due to a misdirected immune reaction against harmless antigens on the one hand, and to a disturbed skin barrier on the other. In recent years, vast efforts have been made to investigate the relevance and details of the immune response to allergens. Clinically, it was demonstrated for the first time that aeroallergen exposure leads to worsening of AD symptoms. An overexpression of Th2 cytokines has been observed in acute and subacute lesions of AD. The clinical impact of the key Th2 cytokines IL-4 and IL-13 on atopic dermatitis has recently been shown in clinical studies with dupilumab, a monoclonal antibody which blocks the IL-4/IL-13 receptor. In vitro data indicate, however, that the T cell response is not solely Th2-polarized but may lead to heterogeneous cytokine production involving IFN-γ and IL-17 in an allergen-dependent manner. Classical thymus-derived Foxp3 T cells have interestingly been detected in elevated numbers in the circulation of AD patients. Therapeutic approaches with allergen specific immunotherapy aim to induce regulatory T cells of the Tr1 type. The strikingly altered microbiome of AD skin with diminished diversity of bacteria on lesional skin but increases of S. aureus colonization and the sensitization against microbial allergens and homologue self-proteins deserve special attention. For the treatment of itch symptoms, which still represent a challenge in daily practice, promising data have been published on the relevance of the H(histamine)4-receptor and on mediators such as IL-31, TSLP.

Consensus Guidelines for the Treatment of Atopic Dermatitis in Korea (Part I): General Management and Topical Treatment

Background

Since the treatment guidelines for atopic dermatitis (AD) were released by the Korean Atopic Dermatitis Association (KADA) work group in 2006, there have been several advances in AD management.

Objective

We aimed to establish updated evidence- and experience-based treatment guidelines for Korean AD.

Methods

We collected a database of references from relevant systematic AD reviews and guidelines regarding general AD management such as bathing and skin care, avoidance of exacerbating factors, education and psychosocial support, and the use of moisturizers and topical anti-inflammatory and antipruritic drugs. Evidence for each statement was graded and the strength of the recommendation for each statement classified. Thirty-nine KADA council members participated in three rounds of voting to establish an expert consensus of recommendations.

Results

Basic AD treatment includes proper bathing and skin care, avoidance of exacerbating factors, proper education and psychosocial support, and use of moisturizers. The regular use of moisturizer has a steroid-sparing effect and reduces relapse episodes. The short- and long-term use of topical corticosteroids and calcineurin inhibitors improves AD symptoms and should be encouraged to use in an active and proactive treatment. Wet-wrap therapy can be used for rapid recovery of acute exacerbation. Topical antipruritic drugs cannot be recommended for the treatment of AD.

Conclusion

This report provides up-to-date evidence- and experience-based treatment guidelines for AD regarding general management and topical treatment. In addition, the average agreement scores obtained by a panel of experts based on the Korean healthcare system and patient adherence are presented.

An innovative oat-based sterile emollient cream in the maintenance therapy of childhood atopic dermatitis

Although emollients are recommended in the management of atopic dermatitis (AD), regimens for emollient maintenance therapy are awaiting validation. We conducted an international, multicenter, open-label trial to assess the effects of a 3-month maintenance treatment regimen with a sterile, preservative-free emollient cream containing oat plantlets in children (ages 6 mos-6 yrs) with moderate AD. After a 14-day run-in stabilization phase using a topical corticosteroid (TCS) treatment of medium potency, 108 children with a SCORing Atopic Dermatitis (SCORAD) index of 20 or less were included in the study. Emollient was applied twice daily for 3 months. Rescue TCS treatment was used only in cases of flare-ups. The SCORAD index, Patient-Oriented SCORAD (PO-SCORAD) index, number of flares, TCS use, and tolerance were assessed at months 1, 2, and 3 (M1, M2, M3). AD severity improved, with a highly significant decrease in the SCORAD and PO-SCORAD indexes at M2 and M3 (p < 0.001). Changes from baseline to M3 were 48.6 ± 73.6% for SCORAD and 29.6 ± 125.3% for PO-SCORAD. The number of flares and TCS use significantly decreased by M3 (both p < 0.001). Very good tolerance was recorded in 100% of children at M2 and M3. Notwithstanding the limitations inherent in open-label trials, twice daily application of the oat-based sterile emollient cream led to a significant improvement of clinical symptoms, evidenced by parallel changes in the SCORAD and PO-SCORAD indexes and fewer flare-ups. Clinical benefit and less TCS use were maintained at M3. Tolerance was very good.

Children with dry skin and atopic predisposition: daily use of emollients in a participant-blinded, randomized, prospective trial

BACKGROUND

Dry skin reflects a skin barrier defect which can lead to atopic dermatitis. Little is known about the distinct effects of emollient use in children with dry skin and atopic predisposition.

OBJECTIVES

We investigated the effects of daily application of pressed ice plant juice (PIPJ)-based emollients and petrolatum-based emollients.

METHODS

Children aged 2-6 years with dry skin and atopic predisposition were randomized into 2 groups: group 1 received emollients containing PIPJ and natural lipids, while group 2 received petrolatum-based emollients. Skin condition and biophysical properties of the skin barrier were assessed at inclusion and weeks 4, 12 and 16.

RESULTS

Skin condition improved significantly in all children. Comparing the groups, children treated with emollients containing PIPJ showed significantly higher stratum corneum hydration values and significantly lower transepidermal water loss values at week 16 on the forearm and forehead. A significant decrease in skin pH was noted in group 2 on the forearm and forehead; group 1 showed a stable course.

CONCLUSION

Early intervention with emollients in children with dry skin condition and atopic predisposition may improve their skin condition during daily emollient application. PIPJ-based formulations may be helpful to maintain skin barrier integrity.
