Patient impact and economic burden of mild-to-moderate atopic dermatitis

Patients' preferences for systemic treatment of atopic dermatitis: safety and efficacy count the most

BACKGROUND

The advent of biologics and janus kinase inhibitors has revolutionized treatment of atopic dermatitis (AD).

OBJECTIVE

To investigate preferences of patients with AD for attributes of currently approved systemic treatments and assess influencing factors.

METHODS

An online discrete choice experiment was conducted in patients with AD throughout Germany to analyze preferences for outcome (probability of (almost) clear skin at week 16, probability of significant itch improvement, time to onset of itch relief and type of side effects) and process attributes (application method and frequency of laboratory tests).

RESULTS

Participants (n = 182, 75.3% female) considered side effects (Relative Importance Score (RIS): 31.2), (almost) clear skin (RIS: 24.2) and probability of itch improvement (RIS: 16.0) most important. Application method (RIS: 14.4), time to onset of itch relief (RIS: 7.4) and frequency of laboratory tests (RIS: 6.8) were less relevant. Preferences were significantly influenced by sex, age, psychiatric comorbidity, current therapy and health-related quality of life according to multivariate regression analysis.

CONCLUSIONS

Participants attached great importance to safety and symptom control. However, preferences were also dependent on individual characteristics, underscoring the importance of personal counseling. Conjoined with medical considerations, patients' preferences have fundamental impact on shared decisions for treatment of AD.

Acupuncture ameliorates atopic dermatitis by modulating gut barrier function in a gut microbiota-dependent manner in mice

OBJECTIVE

Atopic dermatitis (AD) is a chronic inflammatory skin disease that may be linked to changes in the gut microbiome. Acupuncture has been proven to be effective in reducing AD symptoms without serious adverse events, but its underlying mechanism is not completely understood. The purpose of this study was to investigate whether the potential effect of acupuncture on AD is gut microbiota-dependent.

METHODS

AD-like skin lesions were induced by applying MC903 topically to the cheek of the mouse. Acupuncture was done at the Gok-Ji (LI11) acupoints. AD-like symptoms were assessed by lesion scores, scratching behavior, and histopathological changes; intestinal barrier function was measured by fecal output, serum lipopolysaccharide levels, histopathological changes, and mRNA expression of markers involved in intestinal permeability and inflammation. Gut microbiota was profiled using 16S rRNA gene sequencing from fecal samples.

RESULTS

Acupuncture effectively improved chronic itch as well as the AD-like skin lesions with epidermal thickening, and also significantly altered gut microbiota structure as revealed by β-diversity indices and analysis of similarities. These beneficial effects were eliminated by antibiotic depletion of gut microbiota, but were reproduced in gut microbiota-depleted mice that received a fecal microbiota transplant from acupuncture-treated mice. Interestingly, AD mice had intestinal barrier dysfunction as indicated by increased intestinal permeability, atrophy of the mucosal structure (reduced villus height and crypt depth), decreased expression of tight junctions and mucus synthesis genes, and increased expression of inflammatory mediators in the ileum. Acupuncture attenuated these abnormalities, which was gut microbiota-dependent.

CONCLUSION

Acupuncture ameliorates AD-like phenotypes in a gut microbiota-dependent manner and some of these positive benefits are explained by modulation of the intestinal barrier, providing new perspective for non-pharmacological strategies for modulating gut microbiota to prevent and treat AD.

Emollient application from birth to prevent eczema in high-risk children: the BEEP RCT

Background

Atopic eczema is a common childhood skin problem linked with asthma, food allergy and allergic rhinitis that impairs quality of life.

Objectives

To determine whether advising parents to apply daily emollients in the first year can prevent eczema and/or other atopic diseases in high-risk children.

Design

A United Kingdom, multicentre, pragmatic, two-arm, parallel-group randomised controlled prevention trial with follow-up to 5 years.

Setting

Twelve secondary and four primary care centres.

Participants

Healthy infants (at least 37 weeks' gestation) at high risk of developing eczema, screened and consented during the third trimester or post delivery.

Interventions

Infants were randomised (1 : 1) within 21 days of birth to apply emollient (Doublebase Gel®; Dermal Laboratories Ltd, Hitchin, UK or Diprobase Cream®) daily to the whole body (excluding scalp) for the first year, plus standard skin-care advice (emollient group) or standard skin-care advice only (control group). Families were not blinded to allocation.

Main outcome measures

Primary outcome was eczema diagnosis in the last year at age 2 years, as defined by the UK Working Party refinement of the Hanifin and Rajka diagnostic criteria, assessed by research nurses blinded to allocation. Secondary outcomes up to age 2 years included other eczema definitions, time to onset and severity of eczema, allergic rhinitis, wheezing, allergic sensitisation, food allergy, safety (skin infections and slippages) and cost-effectiveness.

Results

One thousand three hundred and ninety-four newborns were randomised between November 2014 and November 2016; 693 emollient and 701 control. Adherence in the emollient group was 88% (466/532), 82% (427/519) and 74% (375/506) at 3, 6 and 12 months. At 2 years, eczema was present in 139/598 (23%) in the emollient group and 150/612 (25%) in controls (adjusted relative risk 0.95, 95% confidence interval 0.78 to 1.16; p = 0.61 and adjusted risk difference -1.2%, 95% confidence interval -5.9% to 3.6%). Other eczema definitions supported the primary analysis. Food allergy (milk, egg, peanut) was present in 41/547 (7.5%) in the emollient group versus 29/568 (5.1%) in controls (adjusted relative risk 1.47, 95% confidence interval 0.93 to 2.33). Mean number of skin infections per child in the first year was 0.23 (standard deviation 0.68) in the emollient group versus 0.15 (standard deviation 0.46) in controls; adjusted incidence rate ratio 1.55, 95% confidence interval 1.15 to 2.09. The adjusted incremental cost per percentage decrease in risk of eczema at 2 years was £5337 (£7281 unadjusted). No difference between the groups in eczema or other atopic diseases was observed during follow-up to age 5 years via parental questionnaires.

Limitations

Two emollient types were used which could have had different effects. The median time for starting emollients was 11 days after birth. Some contamination occurred in the control group (< 20%). Participating families were unblinded and reported on some outcomes.

Conclusions

We found no evidence that daily emollient during the first year of life prevents eczema in high-risk children. Emollient use was associated with a higher risk of skin infections and a possible increase in food allergy. Emollient use is unlikely to be considered cost-effective in this context.

Satisfaction with Control of Mild to Moderate Atopic Dermatitis with Ruxolitinib Cream: US Physician and Patient Perspectives

INTRODUCTION

The 2021 US approval of ruxolitinib cream for treatment of atopic dermatitis (AD) in patients aged ≥ 12 years was based on the results of two pivotal phase 3 studies. Currently, real-world data to describe effectiveness of ruxolitinib cream and physician satisfaction with treatment remain limited. Our objective is to describe disease control among adults with mild to moderate AD prescribed ruxolitinib cream and physician satisfaction with treatment.

METHODS

Data were from the Adelphi AD Disease Specific Programme™, a US real-world, cross-sectional survey of physician-reported data, undertaken between August 2022 and March 2023. For patients aged ≥ 18 years, physicians reported patient demographics, clinical characteristics, treatment patterns, and physician satisfaction with disease control. Descriptive analysis of data for patients with mild to moderate AD prior to the initiation of ruxolitinib cream and treated with ruxolitinib cream for ≥ 1 month was undertaken.

RESULTS

Among physician-reported data from 1360 patients with AD, 149 patients had received ruxolitinib cream (in combination or as monotherapy) for ≥ 1 month, including 59 patients receiving monotherapy. Prior to treatment with ruxolitinib cream, 84.6% of patients had moderate AD (Investigator's Global Assessment, IGA of 3), whereas after treatment (median duration, 26 weeks), only 21.5% had an IGA of 3, with 48.3% of patients having clear or almost clear skin (IGA of 0/1). For these patients, 81.2% were not currently experiencing a flare, and physicians were satisfied with disease control for 87.3%. Results were similar in patients receiving monotherapy. The most frequent physician-reported reasons for prescribing ruxolitinib cream included relieving itch, improving lesion redness/thickness, achieving disease control, and reducing/controlling flares.

CONCLUSIONS

These real-world findings demonstrate effective disease control and physician satisfaction with ruxolitinib cream for the treatment of AD in adults in a clinical practice setting. Outcomes were similar whether ruxolitinib cream was prescribed as monotherapy or in combination regimens, suggesting a role for ruxolitinib cream across the spectrum of disease.

[Incorporation of patient-reported outcomes into pharmacy and dermatology departments, in psoriasis and atopic dermatitis patients, as a tool to improve the healthcare quality and health outcomes]

INTRODUCTION

Patient-reported outcomes (PROs) provide subjective information about their disease, treatment, and quality of life.

OBJECTIVE

To introduce a new system of work coordinated between pharmacists and dermatologists, based on the collection and analysis of PROs to assess its clinical impact as well as patients satisfaction.

METHOD

A prospective single-centre observational study was conducted under clinical conditions and included adult patients diagnosed with psoriasis (PS) and atopic dermatitis (AD) between April-2021 and February-2022. Pharmacists and dermatologists agreed on this systematic work. A REDCap® database was designed to facilitate data collection and the subsequent analysis.

RESULTS

A total of 288 and 41 patients with PS and AD, respectively, were included. Those who started treatment showed significant improvement with a decrease in PROs and clinical parameters (p < 0.001). The pharmacist made 168 and 7 recommendations to dermatologists for PS and AD patients, respectively, of which 66.07% and 57.1% were accepted. The most common recommendations were «consult with rheumatologist» (20.83%), «extend drug regimen» (19.64%) and «consider change in treatment» (11.90%). Adverse events were reported in 55 and 17 patients with PS and AD, respectively. Of 103 patients, 75% were «very satisfied» and 20% «satisfied» with the system.

CONCLUSIONS

This new working system helps to evaluate the short and long-term effectiveness of treatments and also to identify adverse events, alarm symptoms and co-morbidities in order to optimize therapies. Collaboration between pharmacists and dermatologists reduces decision-making time and patients appreciate better clinical care leading to higher patient satisfaction.

SNG100, a novel topical treatment for moderate atopic dermatitis, in patients aged 6 years or older: A randomised, double-blind, active-controlled trial

Background

Atopic dermatitis (AD) is one of the most common inflammatory skin diseases. It is associated with significant itch and impaired quality of life. Systemic treatments are efficient but associated with side effects. Novel topical treatments with a favourable safety profile are needed. SNG100 is a novel composition of hydrocortisone 1% in a cream base comprising sulphated polysaccharide (SPS; extracted from in-house cultivated Porphyridium Cruentum unicellular algae), a well-known hydrating, moisturising and a skin barrier repairing agent.

Objectives

To assess the safety, usability and efficacy of SNG100 cream in patients aged ≥6 years with moderate AD.

Methods

In this proof of concept phase I, double-blind, randomised trial, participants received one of three treatments for 14 days: SNG100 twice daily (BID), hydrocortisone 1% BID or mometasone furoate once daily (QD). The primary endpoint was the safety and tolerability of SNG100 cream compared to hydrocortisone 1% and mometasone furoate. The secondary endpoint was the subject's usability of SNG100. Exploratory efficacy endpoints included percent change from baseline in SCOring AD (SCORAD), Eczema Area and Severity Index, Patient-Oriented Eczema Measure, Dermatology Life Quality Index, pruritus Numerical Rating Score (NRS), peak pruritus-NRS and Investigator's Global Assessment. Subjects were also followed up without any treatment for additional 14 days.

Results

Overall, 66 participants were screened, and 60 patients were randomised. SNG100 demonstrated a high safety profile, similar to marketed products hydrocortisone 1% and mometasone furoate 0.1%, with no unanticipated drug safety related events. SNG100 and mometasone furoate 0.1% cream achieved almost similar and statistically significant greater percentage reductions from baseline in SCORAD as compared to hydrocortisone 1% cream. SNG100 demonstrated significant improvement in NRS as compared to hydrocortisone 1% cream. Remarkably, SNG100 led to a lasting effect with only 29.4% of subjects returning to IGA3 during the follow-up period compared to 50% and 38.9% in the hydrocortisone 1% and in mometasone furoate treatment arms, respectively.

Conclusions

Topical SNG100 is an effective, safe, and well-tolerated innovative treatment for moderate AD. Trial registration number: NCT04615962 (Topical Cream SNG100 for Treatment in Moderate AD Subjects).

Clinically relevant improvements in adults and adolescents with atopic dermatitis who did not achieve Investigator's Global Assessment treatment success following 8 weeks of ruxolitinib cream monotherapy

Ruxolitinib cream is a topical formulation of ruxolitinib, a selective inhibitor of Janus kinase (JAK) 1 and JAK2. In two phase 3 studies in adults and adolescents (aged ≥12 years) with atopic dermatitis (AD; TRuE-AD1/TRuE-AD2), significantly more patients who applied ruxolitinib cream versus vehicle cream achieved Investigator's Global Assessment treatment success (IGA-TS; IGA score of 0/1 with ≥2-point improvement from baseline) at week 8 (primary endpoint). This post hoc analysis evaluated the efficacy, safety, and disease control of ruxolitinib cream in patients with AD who did not achieve IGA-TS at week 8. Patients in TRuE-AD1/TRuE-AD2 (N = 1249) were randomized 2:2:1 to apply twice-daily 0.75% ruxolitinib cream, 1.5% ruxolitinib cream, or vehicle cream for 8 weeks followed by a long-term safety period in which patients applied ruxolitinib cream as needed. In this pooled analysis, clinically meaningful response thresholds included ≥50% improvement in the Eczema Area and Severity Index, ≥2-point reduction in the Itch Numerical Rating Scale, ≥4-point improvement in the Dermatology Life Quality Index (DLQI) or ≥6-point improvement in Children's DLQI, and ≥1-point reduction in IGA from baseline. Among patients who did not achieve IGA-TS at week 8 (n = 584), significantly more patients who applied either strength ruxolitinib cream versus vehicle achieved each response threshold at week 8. A response in ≥1 clinically meaningful endpoint was achieved in significantly more patients who applied ruxolitinib cream (93.4%/90.9% for 0.75%/1.5% ruxolitinib cream, respectively) versus vehicle (69.0%, both P < 0.0001). Progressive improvements in disease control were observed, with many patients achieving IGA-TS by week 52 (55.2%/56.3% for 0.75%/1.5% ruxolitinib cream, respectively). Ruxolitinib cream was well tolerated during the 52-week study in this patient population. Taken together, these results demonstrate that most patients with AD who did not achieve IGA-TS at week 8 have clinically meaningful responses to ruxolitinib cream, and continued therapy beyond 8 weeks could result in additional benefit.

Economic and Humanistic Burden in Paediatric Patients with Atopic Dermatitis

Data concerning the economic and humanistic burden in patients with paediatric atopic dermatitis (AD) and their families are scarce. This retrospective study investigated these burdens in paediatric patients with AD using maintenance treatment with topical corticosteroids and/or conventional systemic immunosuppressants. Patient-reported outcomes regarding quality of life, AD severity, and parental work-related impairment were completed at inclusion. Data on healthcare resource utilization and medication prescription were collected retrospectively over the previous 12 months. Patients were categorized into mild, moderate or severe AD, based on Eczema Area and Severity Index score and medication use. Costs per patient per year per AD severity category were calculated. A total of 101 patients (median age 11.0 years (interquartile range 7.5-14.0), 47.5% men) were included, of whom 38 had mild AD, 37 moderate AD, and 26 severe AD. Mean ± standard deviation (SD) total costs patient per year for mild, moderate and severe AD were €1,812 ± €1,280, €2,680 ± €3,127, and €5,861 ±  €3,993, respectively. Highest total direct and indirect costs were found in patients with severe AD, mainly due to higher healthcare and medication costs. Highest humanistic burden was found in patients with moderate AD. For example, the median (interquartile range) Patient-Oriented Eczema Measure score was significantly higher in these patients compared with mild and severe AD (19.0 (15.0-24.0) vs 12.0 (8.8-15.0) and 17.0 (9.5-22.0), respectively). AD in paediatric patients incurs considerable direct and indirect costs, especially in patients with severe AD. The high humanistic burden in patients with moderate AD underlines the need for effective and safe new treatment options for children with AD.

Factors Predicting Quality of Life Impairment in Adult Patients with Atopic Dermatitis: Results from a Patient Survey and Machine Learning Analysis

INTRODUCTION

Atopic dermatitis (AD) is a chronic, inflammatory skin disorder that impairs patients' quality of life (QoL). Physician assessment of AD disease severity is determined by clinical scales and assessment of affected body surface area (BSA), which might not mirror patients' perceived disease burden.

METHODS

Using data from an international cross-sectional web-based survey of patients with AD and a machine learning approach, we sought to identify disease attributes with the highest impact on QoL for patients with AD. Adults with dermatologist-confirmed AD participated in the survey between July-September 2019. Eight machine learning models were applied to the data with dichotomised Dermatology Life Quality Index (DLQI) as the response variable to identify factors most predictive of AD-related QoL burden. Variables tested were demographics, affected BSA and affected body areas, flare characteristics, activity impairment, hospitalisation and AD therapies. Three machine learning models, logistic regression model, random forest and neural network, were selected on the basis of predictive performance. Each variable's contribution was computed via importance values from 0 to 100. For relevant predictive factors, further descriptive analyses were conducted to characterise those findings.

RESULTS

In total, 2314 patients completed the survey with mean age 39.2 years (standard deviation 12.6) and average disease duration of 19 years. Measured by affected BSA, 13.3% of patients had moderate-to-severe disease. However, 44% of patients reported a DLQI > 10, indicative of a very large to extremely large impact on QoL. Activity impairment was the most important factor predicting high QoL burden (DLQI > 10) across models. Hospitalisation during the past year and flare type were also highly ranked. Current BSA involvement was not a strong predictor of AD-related QoL impairment.

CONCLUSIONS

Activity impairment was the single most important factor for AD-related QoL impairment while current extent of AD did not predict higher disease burden. These results support the importance of considering patients' perspectives when determining the severity of AD.

Natural Green Spaces, Sensitization to Allergens, and the Role of Gut Microbiota during Infancy

The environment plays an instrumental role in the developmental origins of health and disease. Protective features of the environment in the development of asthma and atopy have been insufficiently studied. We used data from the CHILD (Canadian Healthy Infant Longitudinal Development) Cohort Study to examine relationships between living near natural green spaces in early infancy in Edmonton, AB, Canada and the development of atopic sensitization at 1 year and 3 years of age in a cohort of 699 infants, and whether these associations were mediated by infant gut microbiota (measured using 16s V4 amplicon sequencing) at 4 months. The Urban Planning Land Vegetation Index (uPLVI) map of the City of Edmonton was used to assess infants' exposure to natural spaces based on their home postal codes, and atopic sensitization was assessed using skin prink testing (SPTs) for common food and inhalant allergens. Our findings suggest there is a protective effect of natural green space proximity on the development of multiple inhalant atopic sensitizations at 3 years (odds ratio = 0.28 [95% CI 0.09, 0.90]). This relationship was mediated by changes to Actinobacteria diversity in infant fecal samples taken at 4 months. We also found a positive association between nature proximity and sensitization to at least one food or inhaled allergen; this association was not mediated by gut microbiota. Together, these findings underscore the importance of promoting natural urban greenspace preservation to improve child health by reducing atopic disease susceptibility. IMPORTANCE Our findings highlight the importance of preserving natural green space in urban settings to prevent sensitization to environmental allergens and promote early-life gut microbiota pathways to this health benefit. These findings support a mediating role of gut microbiome compositions in health and disease susceptibility. This study used unique, accurate, and comprehensive methodology to classify natural space exposure via a high-resolution topographical map of foliage subtypes within the City of Edmonton limits. These methods are improvements from other methods previously used to classify natural space exposure, such as the normalized density vegetation index from satellite imagery, which is not able to distinguish anthropogenic from green space. The use of these methods and the associations found between natural green space exposure and atopic sensitization outcomes support their use in future studies. Our findings also provide many avenues for future research including longer term follow up of this cohort and investigation of a causal role of reduced Actinobacteria diversity on atopic sensitization development.

Efficacy and safety of topical brepocitinib for the treatment of mild-to-moderate atopic dermatitis: a phase IIb, randomized, double-blind, vehicle-controlled, dose-ranging and parallel-group study

BACKGROUND

Atopic dermatitis (AD) is a prevalent inflammatory, pruritic skin disease. The Janus kinase (JAK) pathway is a treatment target.

OBJECTIVES

To assess the efficacy, safety and pharmacokinetics of topical cream brepocitinib, a small-molecule tyrosine kinase 2 (TYK2)/JAK1 inhibitor, in participants with mild-to-moderate AD.

METHODS

In this phase IIb, double-blind, dose-ranging study, participants were randomized to receive one of eight treatments for 6 weeks: brepocitinib 0·1% once daily (QD), 0·3% QD or twice daily (BID), 1·0% QD or BID, 3·0% QD, or vehicle QD or BID. The primary endpoint was the percentage change from baseline in the Eczema Area and Severity Index (EASI) total score at week 6. Adverse events (AEs) were monitored.

RESULTS

Overall, 292 participants were enrolled and randomized. The brepocitinib 1% QD and 1% BID groups achieved statistically significantly greater (with multiplicity-adjusted P < 0·05 due to Hochberg's step-up method) percentage reductions from baseline in EASI total score at week 6 [least squares mean (90% confidence interval, CI): QD: -70·1 (-82·1 to -58·0); BID: -75·0 (-83·8 to -66·2)] compared with respective vehicle [QD: -44·4 (-57·3 to -31·6); BID: -47·6 (-57·5 to -37·7)]. There was not a dose-dependent trend in AE frequency, and there were no serious AEs or deaths.

CONCLUSIONS

Topical brepocitinib is effective and well tolerated in participants with mild-to-moderate AD. What is already known about this topic? Janus kinase (JAK) inhibitors are in development for treatment of atopic dermatitis (AD). The tyrosine kinase 2 and JAK 1 inhibition by brepocitinib may bring a new profile for topical JAK inhibitors for treatment of mild-to-moderate AD. What does this study add? Topical brepocitinib can provide rapid, effective symptom reduction, and could offer a novel alternative to current topical treatments for mild-to-moderate AD.

Have the prevalence of eczema symptoms increased in the Mexican pediatric population? Prevalence and associated factors according to Global Asthma Network Phase I

Background

In children, atopic dermatitis or eczema is the most common inflammatory disease of the skin. According to the International Study of Asthma and Allergies in Childhood (ISAAC) Phase IIIB in Mexico, 5.8% of children and 4.9% of adolescents had eczema symptoms. In 2012, Global Asthma Network (GAN) was established to update the prevalence of eczema and estimate potential factors contributing to its development.

Objective

To estimate the prevalence and associated factors for atopic eczema symptoms and diagnosis in children and adolescents according to GAN Phase I and compare the results with ISAAC Phase IIIB in Mexico.

Methods

A cross-sectional, multicenter survey was conducted in 15 Mexican centers during the period of 2015-2017 using the GAN Phase I questionnaires in children (6-7-year-olds) and adolescents (13-14-year-olds). The prevalences obtained from the GAN Phase I study, were compared with ISAAC Phase IIIB results; a Spearman's correlation analysis was conducted between temperature, relative humidity, and altitude and eczema symptoms, and a logistic regression was performed to predict current eczema symptoms by age group.

Results

A total of 35 777 children and 41 399 adolescents were included. Since ISAAC Phase IIIB, the prevalence of itchy rash in the past 12 months significantly increased in the children's group [6.6% (95% CI 5.7-7.4) vs 7.8 (95% CI 7.5-8.1), p = 0.000] and adolescents' group [5.8% (95% CI 5.0-6.7) vs 6.7% (95% CI 6.5-7.0), p = 0.000].In the adolescents' group, the prevalence of nocturnal awakenings caused by rash symptoms on more than one night per week had a negative correlation between altitude (Spearman's Rho = -0.558, p value = 0.031), and a positive correlation with the average annual temperature (Spearman's Rho = 0.604, p value = 0.017) and annual relative humidity (Spearman's Rho = 0.742, p value = 0.002). The most significant associations in children were the presence of sneezing or runny or blocked nose in the past 12 months [(OR 3.13, 95% CI 2.60-3.77), p = 0.000], the use of paracetamol in the first year of life ([OR 1.52, 95% CI 1.15-2.01), p = 0.003] and the use of antibiotics in the first year of life [(OR 1.30, 95% CI 1.08-1.55) p = 0.004]. Moreover, altitude at 100-1000 m above sea level was associated with current eczema symptoms in adolescents (p = 0.001).

Conclusions

There has been a significant increase in eczema symptoms in both age groups since ISAAC Phase IIIB study. Additionally, eczema symptoms were associated with temperature, relative humidity, asthma, hay fever symptoms, the use of paracetamol and antibiotics.

How does self-compassion help people adjust to chronic skin conditions? A template analysis study

Objectives

Skin conditions can greatly impact people's lives, but greater understanding of the processes involved in positive adjustment is required. Self-compassion has strong links to wellbeing and adaptive functioning and therefore may play an important role in adjustment to skin conditions.

Design

Template analysis was used to explore how self-compassion operates in people living with skin conditions, with reference to existing theories of self-compassion.

Methods

Semi-structured interviews were conducted with highly self-compassionate people with chronic skin conditions (N = 10). Theoretical models of self-compassion were used in the development of the initial template and interview schedule. Participants were purposively selected on the basis of having high scores on a measure of self-compassion.

Results

Participants reported a variety of ongoing skin-related difficulties and their ways of managing these. Sensitivity to distress and care for wellbeing were identified as foundation themes: necessary components of a compassionate response to distress. Eleven types of difficulty-management strategies built upon these foundation themes: empathy, non-judgement, distress tolerance, self-kindness, mindful attention, perspective-taking, self-talk, self-care, using social support, concealment, and idiosyncratic coping strategies.

Conclusions

Components of self-compassion helped people adjust to chronic skin conditions in a wide variety of ways, indicating that psychological adjustment is not a simple, linear process. Sometimes compassionate responses occurred automatically and sometimes with deliberate effort. Further research on compassion-based interventions for people with skin conditions is warranted.

Atopic dermatitis: pathomechanisms and lessons learned from novel systemic therapeutic options

Atopic dermatitis (AD) is a chronic, heterogenous, inflammatory skin disorder associated with a high skin-related health burden, typically starting in childhood and often persisting into adulthood. AD is characterized by a wide range of clinical phenotypes, reflecting multiple underlying pathophysiological mechanisms and interactions between genetics, immune system dysregulation, and environmental factors. In this review, we describe the diverse cellular and molecular mechanisms involved in AD, including the critical role of T cell-driven inflammation, primarily via T helper (Th) 2- and Th17-derived cytokines, many of which are mediated by the Janus kinase (JAK) signaling pathway. These local inflammatory processes interact with sensory neuronal pathways, contributing to the clinical manifestations of AD, including itch, pain, and sleep disturbance. The recent elucidation of the molecular pathways involved in AD has allowed treatment strategies to evolve from broad-acting systemic immunosuppressive therapies to more targeted agents, including JAK inhibitors and cytokine-specific biologic agents. Evidence from the clinical development of these targeted therapies has reinforced and expanded our understanding of the pathophysiological mechanisms underlying AD and holds promise for individualized treatment strategies tailored to specific AD subtypes.

Living with Atopic Dermatitis as a Young Adult in Relation to Health-related Quality of Life and Healthcare Contacts: A Population-based Study

Most studies of health-related quality of life (HRQoL) and atopic dermatitis are based on data from dermatology clinics. The aim of this study was to determine whether atopic dermatitis affects HRQoL in adolescence and young adulthood, based on data from the population-based cohort BAMSE (Children, Allergy, Environmental, Stockholm, Epidemiology). A further aim was to determine if the use of topical corticosteroids and healthcare contacts affect HRQoL. Participants with data from birth to young adulthood (n=3,064) were included. Two generic instruments were used to measure HRQoL:General Health at age 12, 16 and 24 years and EQ-5D-3L, including EQ-visual analogue scale (EQ-VAS) at age 24 years. In addition, the disease-specific Dermatology Quality Life Index (DLQI) was used at 24 years. Healthcare consultations for atopic dermatitis were obtained from Stockholm Regional Healthcare Data Warehouse (n = 1,944). Participants with atopic dermatitis had an increased odds ratio (OR) of not feeling completely healthy (adjusted OR 1.50; 95% confidence interval (95% CI): 1.30–1.73). Participants with persistent atopic dermatitis, fulfilling atopic dermatitis criteria in the 12- and/or 16- and 24-year follow-ups reported worse EQ-VAS value 70.0 (95% CI 67.3–72.7) in the 25^th percentile, than peers without atopic dermatitis. Over an 8-year period, contact with healthcare was limited (mean number 0.96). In conclusion, atopic dermatitis had a negative impact on HRQoL in young adults from adolescence to adulthood and healthcare consultations were few.

Clinical and Humanistic Burden of Atopic Dermatitis in Europe: Analyses of the National Health and Wellness Survey

Introduction

Atopic dermatitis (AD) is a chronic and relapsing inflammatory skin disease that negatively impacts overall health, quality of life (QoL), and work productivity. Prior studies on AD burden by severity have focused on moderate-to-severe disease. Here, we describe the clinical and humanistic burden of AD in Europe across all severity levels, including milder disease.

Methods

Data were analyzed from the 2017 National Health and Wellness Survey from adult respondents with AD in the EU-5 (France, Germany, Italy, Spain, and the UK). AD disease severity was defined based on self-reported assessments as “mild,” “moderate,” or “severe” and by Dermatology Life Quality Index (DLQI) severity bands. Self-reported outcomes for AD respondents by severity were assessed using propensity score matching. These outcomes included a wide range of selected medical/psychological comorbidities, overall QoL and functional status (EuroQol 5-Dimensions 5-Level and Short Form-36 version 2 questionnaires), and work productivity and activity impairment (Work Productivity and Activity Impairment questionnaire).

Results

In total, 4208 respondents with AD (mild AD, 2862; moderate AD, 1177; severe AD, 169) and 4208 respondents without AD were included in this analysis. Results showed greater burden across severity levels compared with matched non-AD controls. A higher proportion of respondents with mild-to-moderate AD, defined by DLQI severity bands, reported atopic comorbidities (P < 0.05) and a wide range of cardiac, vascular, and metabolic comorbidities, including hypertension, high cholesterol, angina, and peripheral vascular disease (P < 0.005), compared with non-AD controls. Relative to potential impacts of various medical and psychological burdens, respondents with mild-to-moderate AD reported higher activity impairment than controls (P < 0.0001).

Conclusion

Clinical and humanistic burden was observed in European respondents with AD compared with matched non-AD controls across severity levels, with burden evident even in milder disease, highlighting the importance of improving disease management in early stages of AD.

Recent Developments and Advances in Atopic Dermatitis: A Focus on Epidemiology, Pathophysiology, and Treatment in the Pediatric Setting

Atopic dermatitis (AD) is a chronic inflammatory skin disorder that affects a substantial number of children and has a significant negative impact on affected patients and their caregivers/families. Recent studies have led to significant evolutions in the understanding of AD pathogenesis, epidemiology, and treatment. The first point of contact for many patients with new-onset AD is usually with their primary care provider or pediatrician. This underscores the importance for pediatricians to understand the basic pathophysiology and current standards of care for AD. This article provides up-to-date information and reviews the basic principles of AD pathophysiology, diagnosis, and management. In addition, the article highlights recent advances in scientific research regarding the mechanisms involved in the pathogenesis of atopic dermatitis that have resulted in the discovery of novel therapeutic targets and the development of targeted biologic therapies with the potential to revolutionize AD therapy.

A TCM formula VYAC ameliorates DNCB-induced atopic dermatitis via blocking mast cell degranulation and suppressing NF-κB pathway

ETHNOPHARMACOLOGICAL RELEVANCE

A Traditional Chinese Medicine (TCM) formula (VYAC) consists of three herbs including Viola yedoensis Makino, herb (Violaceae, Viola), Sophora flavescens Aiton, root (Fabaceae, Sophora) and Dictamnus dasycarpus Turcz, root and rhizome (Rutaceae, Dictamnus), has been traditionally prescribed to treat various skin diseases in clinic.

AIM OF THE STUDY

This study aims to investigate the therapeutic effects of VYAC on the 2,4-dinitrobenzene (DNCB) induced atopic dermatitis (AD)-like mice and to explore the underlying mechanisms.

MATERIALS AND METHODS

VYAC was extracted with 70 % aqueous ethanol and lyophilized powder was used. AD-like mice were challenged by DNCB, VYAC (150 and 300 mg/kg) were oral administration daily from day 7 to day 28. At the end of experiment, the clinical scores were recorded, serum and skin in the dorsal were isolated to evaluate the therapeutic effects of VYAC. RBL-2H3 cells were stimulated with C48/80 for degranulation and plasmids expressing constitutively active form of Syk (Silence or overexpression) were transfected into RBL-2H3 cells to explore the underlying mechanisms in vitro.

RESULTS

VYAC significantly ameliorated the cardinal symptoms in the DNCB-induced AD-like mice by repairing the skin barrier function, inhibiting mast cells infiltration, restraining the serum IgE and histamine release and decreasing TNF-α, IL-4 as well as Syk mRNA level in dorsal skin and alleviating inflammation. Besides, VYAC significantly blocked RBL-2H3 cells degranulation, reduced β-hexosaminidase and histamine release, and suppressed NF-κB pathway. What's more, the degranulation of RBL-2H3 was reduced after Syk silence and increased after Syk overexpression.

CONCLUSION

Our findings clearly suggested that VYAC treat AD through inhibiting the inflammatory mediator productions and blocking mast cell degranulation via suppressing Syk mediated NF-κB pathway.

What are the highest yielding search strategy terms for systematic reviews in atopic dermatitis? A systematic review

The impact of search strategies on systematic reviews (SR) of atopic dermatitis (AD) is unknown. The purpose of this review was to evaluate search strategies used in SR of AD and their impact on the frequency of manuscripts identified. MEDLINE and EMBASE were searched for SR related to AD. Simulations were performed by running combinations of search terms in MEDLINE and EMBASE. Overall, 250 SR met inclusion criteria, of which 225 specified search strategies. SR using 5-6 terms (20.0% to 12.1%) or ≥ 7 (40.0% to 18.8%) terms decreased, whereas SR using 3-4 terms numerically increased (18.8% to 30.2%) and 1-2 terms remained similar (37.5% to 38.9%) from 1999-2009 to 2015-2019. The most commonly searched terms were "atopic dermatitis" (n = 166), followed by "eczema" (n = 156), "dermatitis atopic'" (n = 81), "atopic eczema" (n = 74), "neurodermatitis" (n = 59), "Besniers prurigo" (n = 29), "infantile eczema" (n = 27), and "childhood eczema" (n = 19). Simulations revealed that "eczema" and "atopic dermatitis" yielded the most hits. The number of search terms that maximized hits in MEDLINE and EMBASE was 5 and 4, respectively. Search strategies for AD were heterogeneous, with high proportions of search strategies providing few search hits. Future studies should use standardized and optimized search terms.

High Levels of Psychological Distress, Sleep Disturbance, and Alcohol Use Disorder in Adults With Atopic Dermatitis

BACKGROUND

The burden of illness associated with atopic dermatitis (AD) is significant and multidimensional, especially in those with moderate to severe disease.

OBJECTIVE

Our objective was to evaluate the disease burden of patients with AD in relation to psychological distress, sleep disturbance, and alcohol misuse.

METHODS

Patients with AD, attending 2 tertiary referral centers in Dublin, Ireland, were recruited. A series of validated questionnaires were used including the Patient-Oriented Eczema Measure, Dermatology Life Quality Index (DLQI), Center for Epidemiologic Studies-Depression Scale, Quality of Life in Atopic Dermatitis Questionnaire, Alcohol Use Disorders Identification Test, and Pittsburgh Sleep Quality Index. The Eczema Area and Severity Index was calculated contemporaneously with the questionnaire completion.

RESULTS

One hundred patients completed the questionnaire, of whom 52% were female. Sixty-three percent of patients experienced impaired quality of life as measured by the DLQI. Higher DLQI scores correlated with decreasing age (r = 0.3277, P < 0.0009). Thirty percent were found to be at risk of clinical depression, and higher Center for Epidemiologic Studies-Depression Scale scores correlated with a younger age and eczema severity. Sleep disturbance was greater in those at risk of depression (mean = 10.40 vs 5.79, P < 0.0001). Patients with moderate to severe AD were more likely to score higher on the Alcohol Use Disorders Identification Test, and 25% met the criteria for alcohol use disorder. In relation to sleep, 73% of patients scored higher than 5 on the Pittsburgh Sleep Quality Index, which signifies poor sleep quality.

CONCLUSIONS

Patients with AD endure a significant burden on health with regard to mental well-being, alcohol use, and sleep quality. Clinicians should consider screening patients for these comorbidities.

Unmet needs in atopic dermatitis management: an expert consensus

INTRODUCTION

Atopic dermatitis (AD) has substantial negative impact on patients' quality of life. Although considerable advances have been made in understanding the pathogenesis and its treatment, there is still limited transfer of this knowledge into daily management. Aiming to identify unmet needs in clinical management of patients with AD, we used a Delphi consensus process.

METHODS

A set of statements regarding diagnosis, management, prognosis, and treatment was identified by five experts (Steering Committee). Then, the Steering Committee and a second group of four clinicians were involved in a Delphi process. Lastly, agreement was assessed in a larger panel of Italian clinicians.

RESULTS

Overall, 37 clinicians participated to the process. 17 statements reached strong agreement and 2 reached weak agreement.

CONCLUSIONS

In general, the statements reflected the need for accurate and effective diagnostic criteria to support clinical experience, especially in the atypical forms of AD. Moreover, prognostic criteria are needed to predict the duration of adult-onset AD. The identification of biomarkers was considered to be useful for clinical management of AD at all stages of disease. Lastly, greater emphasis should be placed on patient education and development of effective tools that can aid informing patients about their disease and its treatment.

Inadequate Disease Control, Treatment Dissatisfaction, and Quality-of-Life Impairments Among US Patients Receiving Topical Therapy for Atopic Dermatitis

Introduction

Patients with atopic dermatitis (AD) experience burdensome symptoms and impaired quality of life (QoL). The objective of this study was to investigate the effects of topical AD therapies on disease control, physician and patient treatment satisfaction, and QoL in a real-world setting.

Methods

This was a retrospective, point-in-time study of physician-completed medical records and patient surveys drawn from two Adelphi AD Disease Specific Programmes™ (1. adults ≥ 18 years old; 2. pediatrics ≤ 17 years old) in the USA. Eligible physicians completed patient record forms and provided disease control assessments. Physicians and matched patients were surveyed regarding their satisfaction with current treatment. Patient-reported outcomes included the Dermatology Life Quality Index (DLQI), Children’s DLQI (CDLQI), Patient-Oriented Eczema Measure (POEM), and the Work Productivity and Activity Impairment (WPAI) questionnaire.

Results

A total of 394 adult (topicals only, n = 284; topical plus systemic, n = 110) and 144 adolescent (aged 12–17 years; topicals only, n = 114; topical plus systemic, n = 30) patients who had received their current treatment for at least 1 month were included. Overall, 24.5% of patients had physician-reported uncontrolled disease (adults, 22.8%; adolescents, 29.2%). Rates of physician- and patient-reported dissatisfaction with current treatment were 32.0% (adults, 28.2%; adolescents, 42.4%) and 24.8% (adults, 24.0%; adolescents, 26.8%), respectively, and were higher for patients with uncontrolled versus controlled disease. Poorer disease control and higher rates of treatment dissatisfaction were generally reported among patients receiving topical plus systemic therapy versus topicals alone. Patients with uncontrolled versus controlled disease reported more impairment in the DLQI, CDLQI, POEM, and WPAI (P < 0.05 for all), with generally greater impairments observed among patients on topical plus systemic therapy versus topicals alone.

Conclusion

Patients receiving topical AD therapies experienced uncontrolled disease and reported decreased overall functioning and lower QoL. An unmet need for topical AD treatments that improve disease control and patient outcomes exists.

Atopic dermatitis (or eczema) is a common skin condition that causes dry, cracked, and itchy skin. Patients are frequently prescribed topical therapy, such as ointments and creams, to apply directly to the affected skin. Additionally, patients may be prescribed systemic therapies, which are oral or injectable medications that work throughout the entire body. This study included 394 adults and 144 adolescents (aged 12–17 years) with atopic dermatitis. All patients in the study were receiving topical therapy, and some received both topical and systemic therapy. The goal of the study was to evaluate how satisfied patients and their doctors were with current treatment and to learn how patients in the study felt about their quality of life. Patients and their doctors completed surveys that asked about feelings, symptoms, and whether their condition affects their work. The study results showed that patients had high levels of dissatisfaction with their treatment. Doctors reported that between one-fifth and one-quarter of adult patients and up to one-half of adolescent patients had uncontrolled disease (defined as changeable or worsening). Patients with uncontrolled disease reported higher dissatisfaction with their therapy and a negative outlook on their quality of life versus those with controlled disease (defined as stable or improving by their doctors). In summary, doctors and their patients currently using topical medications to treat atopic dermatitis reported that treatments were not working well enough and that uncontrolled disease was negatively affecting patients’ quality of life and work, indicating that additional treatment options are needed.

Pharmacokinetics of Ruxolitinib in Patients with Atopic Dermatitis Treated With Ruxolitinib Cream: Data from Phase II and III Studies

BACKGROUND

Pathogenesis of atopic dermatitis (AD) involves the Janus kinase (JAK)/signal transducer and activator of transcription (STAT) pathway. A cream formulation of ruxolitinib, a potent selective JAK1/JAK2 inhibitor, was developed for topical delivery.

METHOD

Pharmacokinetic data were obtained from three double-blind, vehicle-controlled studies in patients with AD: a phase II study with ruxolitinib cream 0.15%, 0.5%, or 1.5% once daily or 1.5% twice daily (BID), and two phase III studies with 0.75% or 1.5% BID. Effects of baseline characteristics on pharmacokinetics were examined. Correlations were attempted between plasma concentrations and change in hematological parameters over time.

RESULTS

Ruxolitinib plasma concentrations at steady-state (Css) increased with cream strength in a less-than-dose-proportional manner. In the phase III studies, overall mean (standard deviation [SD]) Css after ruxolitinib cream 0.75% and 1.5% BID (23.8 [35.0] and 35.7 [55.0] nM) were a fraction of the half-maximal inhibitory concentration for thrombopoietin-stimulated phosphorylated STAT3 inhibition (281 nM), a JAK/STAT signaling marker. Three covariates were identified for Css: dose, percent body surface area (%BSA) treated, and baseline Investigator's Global Assessment score. Mean (SD) bioavailability of ruxolitinib cream 1.5% BID was 6.22% (7.66%). There were no correlations between Css and any hematological changes except for a transient increase in platelets at week 2.

CONCLUSIONS

Plasma ruxolitinib concentrations after treatment with topical ruxolitinib cream in patients with up to 20% BSA affected by AD are not expected to lead to systemic plasma concentrations that may be associated with adverse effects commonly associated with oral JAK inhibitors.

Efficacy and safety of ruxolitinib cream for the treatment of atopic dermatitis: Results from 2 phase 3, randomized, double-blind studies

BACKGROUND

Ruxolitinib (RUX) cream demonstrated potent anti-inflammatory and antipruritic efficacy in a phase 2 study in adults with atopic dermatitis (AD).

OBJECTIVE

To evaluate 8-week efficacy and safety in 2 phase 3 studies of RUX cream in patients with AD.

METHODS

Topical Ruxolitinib Evaluation in Atopic Dermatitis Study 1 (NCT03745638) and Study 2 (NCT03745651) enrolled patients aged ≥12 years with AD for ≥2 years, an Investigator's Global Assessment score of 2/3, and 3%-20% affected body surface area. Patients were randomized 2:2:1 to twice-daily 0.75% RUX cream, 1.5% RUX cream, or vehicle cream for 8 continuous weeks. The primary endpoint was Investigator's Global Assessment treatment success at week 8 (Investigator's Global Assessment score of 0/1 and ≥2-grade improvement from baseline).

RESULTS

In the Topical Ruxolitinib Evaluation in Atopic Dermatitis Study 1 and 2, 631 and 618 patients were randomized (631/577 analyzed for efficacy). Significantly more patients achieved Investigator's Global Assessment treatment success with 0.75% RUX cream (50.0%/39.0%) and 1.5% RUX cream (53.8%/51.3%) versus vehicle (15.1%/7.6%; P < .0001) at week 8. Significant itch reductions versus vehicle were reported within 12 hours of first application of 1.5% RUX (P < .05). Application site reactions were infrequent (<1%) and lower with RUX versus vehicle; none were clinically significant.

LIMITATIONS

Longer-term safety data are not yet available.

CONCLUSIONS

RUX cream showed anti-inflammatory and prompt antipruritic effects with superior efficacy versus vehicle and was well tolerated.

Topical therapy of atopic dermatitis with a focus on pimecrolimus

Atopic dermatitis (AD) is a chronic and relapsing, inflammatory skin disease characterized by impaired skin barrier function and immune system dysregulation that results in dryness, skin microbiome dysbiosis and intense pruritus. It is highly heterogeneous, and its management is demanding. Patients with AD are at greater risk of comorbidities such as attention-deficit hyperactivity disorder as well as other atopic diseases. Early-onset AD cases typically improve or resolve in late childhood; however, it is proposed that the prevalence of persistent or adult-onset AD is higher than previously thought. Basic therapy consists of emollient application and trigger avoidance, and when insufficient, topical corticosteroids (TCS) are the first-line treatment. However, corticophobia/steroid aversion and TCS side-effects, particularly on sensitive skin areas, lead to low compliance and insufficient disease control. Several long- and short-term randomized controlled and daily practice studies have demonstrated that topical calcineurin inhibitors, such as pimecrolimus, have similar anti-inflammatory effects to low-to-medium strength TCS, reduce pruritus and improve the quality of life of patients. In addition, pimecrolimus does not cause skin atrophy, is steroid-sparing and has a good safety profile, with no evidence for an increased risk of malignancies or skin infections. In general, pimecrolimus cream is well-accepted and well-tolerated, encouraging patient adherence and leading to its use by many physicians as a preferred therapy for children and sensitive skin areas.

Clinical and Economic Burden of Pediatric Mild-to-Moderate Atopic Dermatitis: A Population-Based Nested Case-Control Study in Sweden

Introduction

Atopic dermatitis (AD) is a chronic, relapsing inflammatory skin condition characterized by pruritic, eczematous lesions. Recent evidence suggests that AD may be a systemic disorder, implying that management of this disease extends beyond merely controlling symptoms associated with AD. Even though this disease is highly prevalent in children and patients typically present with mild-to-moderate symptoms, the disease burden is not well established.

Methods

A large, retrospective cohort study of Swedish population data was conducted to compare the clinical burden in terms of healthcare resource use and direct medical costs for pediatric mild-to-moderate (pM2M) AD patients (≤ 14 years of age, N = 87,721) with matched controls. The burden of a severe AD cohort was also evaluated. Severity of AD was defined by treatment usage and systemic treatment was used as a proxy for severe AD. A robust approach was used by including any type of secondary care visits known to be more common in AD patients than in the general population; however, data for primary care visits were not available.

Results

For healthcare resource use, the incidence rate ratio (pM2M AD versus reference cohort) of secondary care visits ranged from 1.56 to 2.35 during each of 5 years after AD onset (all p < 0.001), with largest differences seen in years 1–2. The average direct medical cost (SD) was €1111 (3416) and €524 (2446) in the pM2M AD and reference cohorts, respectively. The corresponding estimate in the severe AD cohort was €1906 (7067). Including all secondary care visits and pharmacy-dispensed medications, the pM2M AD cohort was shown to have an additional €118.9 million in direct medical costs over 5 years compared with the reference cohort.

Conclusions

This study shows significant clinical and economic burden of pM2M AD with important secondary care resource utilization, suggesting a need for further research to increase treatment options and improve the management of these patients.

Illness perceptions and quality of life in families with child with atopic dermatitis

OBJECTIVE

To assess the Quality of Life (QoL) of children with Atopic Dermatitis (AD) and their families and the impact of the mothers' illness perceptions on the family QoL.

MATERIALS AND METHODS

Seventy-five children with AD (54 infants and 21 children) and their mothers participated in the study. The following questionnaires were administrated: 1. Brief Illness Perception Questionnaire (Brief IPQ); 2. Infant's Dermatitis Quality of Life Index (IDQOL); 3. Children's Dermatology Life Quality Index (CDLQI); 4. Dermatitis Family Impact Questionnaire (DFIQ) and 5. The Severity Scoring of Atopic Dermatitis (SCORAD).

RESULTS

Atopic dermatitis had a moderate impact on the QoL of the infants (6.67±5.30), children (7.86±7.19) and their families (9.42±7.03). The DFIQ was associated with certain dimensions of the Brief IPQ, specifically, with Illness Identity (greater symptom burden) (r=0.615, p=0.000), beliefs about the Consequences of the illness (r=0.542, p=0.000), the Concerns (r=0.421, p=0.000) and the Emotional Representations (r=0.510, p=0.000). Correlation was demonstrated between IDQOL and DFIQ (r=0.662, p=0.000) and between CDLQI and DFIQ (r=0.832, p=0.000), and a weaker correlation between SCORAD and DFIQ (r=0.255, p=0.035). The chronicity of the AD showed negative association with DFIQ (p<0.001).

CONCLUSIONS

The QoL of families with a child with AD is associated with the mother's illness perceptions about AD, the children's QoL and with both the severity and the chronicity of the disease. Therefore, clinicians should pay attention not only to the clinical characteristics of the children, but also to the parents' beliefs and emotions, to improve the family QoL.

Improvement in disease severity and pruritus outcomes with crisaborole ointment, 2%, by baseline atopic dermatitis severity in children and adolescents with mild-to-moderate atopic dermatitis

BACKGROUND/OBJECTIVES

Crisaborole ointment, 2%, is a nonsteroidal phosphodiesterase 4 inhibitor for the treatment of mild-to-moderate atopic dermatitis (AD). This pooled post hoc analysis of two phase 3 trials (NCT02118766, NCT02118792) assessed improvement and time to improvement in Investigator's Static Global Assessment (ISGA) and Severity of Pruritus Scale (SPS) outcomes in pediatric patients with mild-to-moderate AD.

METHODS

Patients aged ≥2 years were randomly assigned 2:1 to receive twice-daily crisaborole or vehicle for 28 days. Patients aged 2-17 years were pooled for this analysis. Proportions of patients and time to achieving ISGA success (clear [0] or almost clear [1] with ≥2-grade improvement from baseline), ISGA clear/almost clear, ≥1-grade improvement in ISGA, SPS success (SPS score ≤1 with ≥1-grade improvement), or ≥1-grade improvement in SPS score were analyzed and stratified by baseline ISGA.

RESULTS

At first postbaseline assessment (day 8), significantly higher proportions of crisaborole- than vehicle-treated patients achieved ISGA success, ISGA clear/almost clear, ≥1-grade ISGA improvement, SPS success, or ≥1-grade improvement in SPS regardless of baseline ISGA. Differences were significantly greater over time for all outcomes for patients with moderate baseline ISGA and numerically greater for those with mild baseline ISGA. Median times to ISGA and SPS outcomes were shorter for crisaborole versus vehicle.

CONCLUSION

Improvement in ISGA and SPS outcomes were observed with crisaborole in pediatric patients with mild-to-moderate baseline AD.

HP-NAP ameliorates OXA-induced atopic dermatitis symptoms in mice

BACKGROUND

Atopic dermatitis (AD) is a chronic skin inflammatory disease characterized by disequilibrium between Th1/Th2 lymphocytes. Helicobacter pylori neutrophil-activating protein (HP-NAP) has been reported that it has the potential immunomodulatory effect able to regulate the Th1/Th2 balance.

OBJECTIVE

This study aimed to investigate the therapeutic effect of HP-NAP in AD mice model.

METHODS

The model of AD was built with oxazolone (OXA) in BALB/c mice, then HP-NAP was used to treat AD by intraperitoneal injection. Ear thickness was measured by a digital thickness gauge. The ears tissues were collected and subjected to hematoxylin-eosin (H&E) and toluidine blue (TB) staining. The mRNA expression levels of inflammatory cytokines (IL-1β, IL-5, IL-6, and TNF-α) in ear tissue were measured using reverse transcription-quantitative polymerase chain reaction (RT-qPCR). The secretion of IgE, IL-4, and IFN-γ was measured by enzyme-linked immunosorbent assay (ELISA).

RESULTS

Treatment with HP-NAP successfully alleviated the symptoms of AD, such as erythema, horny substance, and swelling. The infiltration of lymphocytes and mast cells were significantly reduced following HP-NAP therapy. The secretion of IgE and IL-4 was significantly attenuated following treatment with HP-NAP. Additionally, HP-NAP observably downregulated inflammatory cytokine expression (e.g. IL-1β, IL-5, IL-6, and TNF-α) in ear tissues.

CONCLUSIONS AND CLINICAL RELEVANCE

Taken together, our results showed that HP-NAP possessed the potential to be a novel immunomodulatory candidate drug against AD.

The psychosocial adaptation of patients with skin disease: a scoping review

BACKGROUND

Skin disease is a global public health problem that often has physiological, psychological and social impacts. However, it is not very clear how to adapt to these impacts, especially psychosocial adaptation of patients with skin disease.

METHODS

We searched EMBASE, PubMed, CINAHL and PsycINFO from 2009 to 2018. The following themes were extracted from the included articles: the concepts, related factors, and interventions for psychosocial adaptation of patients with skin disease. Two reviewers independently screened and analyzed.

RESULTS

From 2261 initial records, 69 studies were identified and analyzed. The concept of psychosocial adaptation in patients with skin disease was referred to under an assortment of descriptions. The related factors for psychosocial adaptation in patients with skin disease included the following: demographic factors (sex, age, education level, ethnicity, BMI, sleep quality, marital status, exercise amount, family history, the use of topical treatment only, personality and history of smoking); disease-related factors (disease severity, clinical symptoms, localization and duration); psychological factors (anxiety/depression, self-esteem, body image, stigma and suicidal ideation); and social factors (social support, social interaction, sexual life, economic burden and social acceptance). Despite being limited in quantity, several studies have clarified the benefits of adjuvant care in the form of cognitive behavioral training, educational training and self-help programs, all of which have become common methods for dealing with the psychosocial impacts.

CONCLUSIONS

Based on the previous literatures, we constructed a protocol of care model for psychosocial adaptation in patients with skin disease. It not only provided the direction for developing new instruments that could assess psychosocial adaptation statue, but also a basis for helping patients adjust to changes in skin disease.

Targeting the Janus Kinase Family in Autoimmune Skin Diseases

Autoimmune skin diseases are characterized by significant local and systemic inflammation that is largely mediated by the Janus kinase (JAK)-signal transducer and activator of transcription (STAT) pathway. Advanced understanding of this pathway has led to the development of targeted inhibitors of Janus kinases (JAKinibs). As a class, JAK inhibitors effectively treat a multitude of hematologic and inflammatory diseases. Growing evidence suggests that JAK inhibitors are efficacious in atopic dermatitis, alopecia areata, psoriasis, and vitiligo. Additional evidence suggests that JAK inhibition might be broadly useful in dermatology, with early reports of efficacy in several other conditions. JAK inhibitors can be administered orally or used topically and represent a promising new class of medications. Here we review the evolving data on the role of the JAK-STAT pathway in inflammatory dermatoses and the potential therapeutic benefit of JAK-STAT antagonism.
