Abstract
Whereas clinically apparent atopic dermatitis (AD) can be confirmed by validated diagnostic criteria, the preclinical phenotype of infants who eventually develop AD is less well-characterized. Analogous to unaffected or nonlesional skin in established AD, clinically normal-appearing skin in infants who will develop clinical AD has distinct changes. Prospective studies have revealed insights into this preclinical AD phenotype. In this study, we review the structural, immunologic, and microbiome nature of the preclinical AD phenotype. Determination of markers that predict the development of AD will facilitate targeting of interventions to prevent the development or reduce the severity of AD in infants.

Abstract
BACKGROUND Chronic spontaneous urticaria (CSU) is a common, debilitating skin disorder characterized by recurring episodes of raised, itchy and sometimes painful wheals lasting longer than 6 weeks. CSU is mediated by mast cells which are absent from peripheral blood. However, lineage-CD34hiCD117int/hiFcεRI+ cells in blood have previously been shown to represent a mast cell precursor. METHODS We enumerated FcεRI-, FcεRI+ and FcεRIhi lineage-CD34+CD117+ cells using flow cytometry in blood of patients with CSU (n = 55), including 12 patients receiving omalizumab and 43 not receiving omalizumab (n = 43). Twenty-two control samples were studied. Disease control and patient response to omalizumab was evaluated using the urticaria control test. We performed single-cell RNA sequencing (scRNA-Seq) on lineage-CD34hiCD117hi blood cells from a subset of patients with CSU (n = 8) and healthy controls (n = 4). RESULTS CSU patients had more lineage-CD34+CD117+FcεRI+ blood cells than controls. Lineage-CD34+CD117+FcεRI+ cells were significantly higher in patients with CSU who had an objective clinical response to omalizumab when compared to patients who had poor disease control 90 days after initiation of omalizumab. scRNA-Seq revealed that lineage-CD34+CD117+FcεRI+ cells contained both lymphoid and myeloid progenitor lineages, with omalizumab responsive patients having proportionally more myeloid progenitors. The myeloid progenitor lineage contained small numbers of true mast cell precursors along with more immature FcεRI- and FcεRI+ myeloid progenitors. CONCLUSION Increased blood CD34+CD117+FcεRI+ cells may reflect enhanced bone marrow egress in the setting of CSU. High expression of these cells strongly predicts better clinical responses to the anti-IgE therapy, omalizumab.

Abstract
Therapeutic strategies with proven efficacy for chronic cutaneous graft-versus-host disease (GvHD) are limited, with long-term oral glucocorticoids remaining the first-line treatment. Prolonged treatment with glucocorticoids contributes to the significantly increased risk of nonrelapse mortality and substantial deficit in quality of life reported in paediatric transplant patients with chronic GvHD. We report a case of atopic dermatitis-like chronic cutaneous GvHD responding to dupilumab, allowing for the eventual withdrawal of oral glucocorticoids.

Abstract
BACKGROUND The STOP AD study, a randomized, open-label trial evaluating the effect of short-term (first four postnatal days to 8 weeks) skin barrier protection using AVEENO® Dermexa Fast & Long-Lasting Balm in infants with a parent with allergic disease, demonstrated decreased cumulative incidence and decreased prevalence of AD at 12 months of age. OBJECTIVE We aimed to identify skin biomarkers in the STOP AD study that are associated with risk of development of AD. METHODS Skin swabs were collected from the cheek and antecubital fossa (AF) at baseline, 8 weeks, and 12 months from subsets of study participants from each of the intervention arm (43 of 119) and control arm (43 of 138) and were analyzed for specific cytokines (CCL27, CXCL2, hBD1, IL18, IL8, IL1α, IL1RA, IL1β, S100A8/9, IL36γ) by ELISA. RESULTS Higher titers of S100A8/9 at the AF at 8 weeks in infants with filaggrin wild type genotype (FLGwt), but not in those with filaggrin loss-of-function mutations (FLGmut), predicted: 1) Development of AD in the first year of life (p=0.033); 2) Presence of AD at 6 months or 12 months of age (p=0.009 and 0.035, respectively); 3) Persistence of AD between 6 and 12 months of age (p<0.001); 4) Development of AD with the emollient intervention. CONCLUSION Increased titers of S100A8/9 from skin swabs of the AF in high-risk infants at 8 weeks with FLGwt was predictive of AD developing in the first year of life and of other AD features. These findings suggest that there are different molecular pathways leading to AD in FLGmut individuals and in FLGwt individuals. Early identification of infants who are likely to develop AD will allow more targeted interventions.

Abstract
BACKGROUND Atopic dermatitis (AD), a relapsing, inflammatory skin disease, is associated with pruritus that can negatively affect patients' quality of life. Understanding the burden of AD is critical for informing and tailoring treatment and disease management to improve patient outcomes. This study characterized global treatment patterns and the clinical, psychosocial and economic burden of moderate-to-severe AD. METHODS MEASURE-AD was a cross-sectional 28-country study in patients with physician-confirmed moderate-to-severe AD who were either receiving or eligible for systemic therapy for AD. Patients ≥12 years were enrolled between December 2019 and December 2020 while attending routine office or clinic visit. Primary outcomes included Worst Pruritus Numeric Rating Scale (WP-NRS; range: 0-10) and Dermatology Life Quality Index (DLQI; range: 0-30) and Children's DLQI (CDLQI; range: 0-30). Secondary outcomes included physician- and patient-reported clinical, psychosocial and economic burden. RESULTS Of the 1591 patients enrolled, 1558 (1434 adults and 124 adolescents) fulfilled all patient selection criteria and were included in this analysis. Almost all patients (98.4%) in the total population were using AD medications and more than half (56%) were receiving systemic medication (15% systemic monotherapy). The most used systemic therapies were dupilumab (56.3%), systemic glucocorticoids (18.1%) and methotrexate (16.2%). Mean WP-NRS was 5.3 in the total population, and most patients (≥55%) reported moderate-to-severe pruritus (WP-NRS ≥4). Mean DLQI was 10.8 and mean CDLQI was 9.6. Secondary endpoints demonstrated substantial clinical, psychosocial, and economic burden of disease. Subgroup analysis demonstrated that patients receiving systemic therapy had lower disease burden than those not taking systemic medications. CONCLUSIONS While systemic therapy lowers overall disease burden, patients with moderate-to-severe AD continue to have substantial multidimensional disease burden and uncontrolled disease. Overall, there is a need for effective disease management, including effective treatments that improve patients' psychosocial outcomes and reduce the economic burden of AD.

Abstract
Atopic dermatitis (AD) is the most common inflammatory skin disease worldwide, affecting 20% of children and 5% of adults. One critical component in the pathophysiology of AD is the epidermal skin barrier, with its outermost layer, the stratum corneum (SC), conferring biochemical properties that enable resilience against environmental threats and maintain homeostasis. The skin barrier may be conceptualized as a key facilitator of complex interactions between genetics, host immunity, the cutaneous microbiome, and environmental exposures. The key genetic risk factor for AD development and persistence is a loss-of-function mutation in FLG, with recent advances in genomics focusing on rare variant discovery, establishment of pathogenic mechanisms, and exploration of the role of other epidermal differentiation complex gene variants in AD. Aberrant type 2 inflammatory responses down-regulate the transcription of key epidermal barrier genes, alter the composition of SC lipids, and induce further injury through a neurocutaneous feedback loop and the itch-scratch cycle. The dysbiotic epidermis exhibits reduced bacterial diversity and enhanced colonization with Staphylococcus and Malassezia species, which contribute to both direct barrier injury through the action of bacterial toxins and perpetuation of the inflammatory cascades. Enhanced understanding of each of the pathogenic mechanisms underpinning barrier disruption has led to the development of novel topical and systemic molecules, including interleukin (IL)-4Ra, IL-13, PDE4, and Janus-associated kinase inhibitors, whose clinical effectiveness exceeds conventional treatment modalities. In this narrative review, we aim to summarize the current understanding of the above-mentioned pathophysiological and therapeutic mechanisms, with a focus on the genetic, cellular, and molecular mechanisms underpinning AD development.

Abstract
INTRODUCTION Immune-mediated inflammatory diseases including rheumatoid arthritis (RA), psoriatic arthritis (PsA), ankylosing spondylitis (AS), non-radiographic axial spondylarthritis (nr-axSpA), atopic dermatitis (AD), ulcerative colitis (UC), and Crohn's disease (CD) pose a substantial burden on patients and their quality of life. Upadacitinib is an orally administered, selective, and reversible Janus kinase inhibitor indicated for seven conditions, but data on its safety versus other active treatments are limited. A systematic literature review of indirect and direct treatment comparisons of randomized controlled trials (RCTs) was conducted to assess the safety profile of upadacitinib. METHODS MEDLINE, Embase, and Cochrane Library databases were searched for indirect and direct treatment comparisons of RCTs that (1) included licensed upadacitinib dosages; (2) studied any of the seven conditions; (3) reported any adverse events (AEs), serious AEs (SAEs), AEs leading to discontinuation, major adverse cardiovascular event, venous thromboembolism, malignancies, infections or serious infections, and death; and (4) were published between January 2018 and August 2022. RESULTS A total of 25 studies were eligible for inclusion. SAEs, AEs leading to discontinuation, and any AEs were commonly studied. RA was the most studied condition, followed by AD and UC. Most studies (16/25, 64%) reported no statistically significant difference in the studied safety outcomes between upadacitinib and other active treatments (e.g., tumor necrosis factor blockers, interleukin receptor antagonists, integrin receptor antagonists, T cell co-stimulation modulator), or placebo (placebo ± methotrexate or topical corticosteroids). Other studies (9/25, 36%) reported mixed results of no statistically significant difference and either statistically higher (8/25, 32%) or lower rates (1/25, 4%) on upadacitinib. CONCLUSION Most studies suggested that upadacitinib has no statistically significant difference in the studied safety outcomes compared to active treatments or placebo in patients with RA, PsA, AS, AD, UC, and CD. A few studies reported higher rates, but findings were inconsistent with limited interpretation.

Abstract
Atopic dermatitis (AD), the most burdensome skin condition worldwide, is influenced by climatic factors and air pollution; however, the impact of increasing climatic hazards on AD remains poorly characterized. Leveraging an existing framework for 10 climatic hazards related to greenhouse gas emissions, we identified 18 studies with evidence for an impact on AD through a systematic search. Most climatic hazards had evidence for aggravation of AD the impact ranged from direct effects like particulate matter-induced AD exacerbations from wildfires to the potential for indirect effects like drought-induced food insecurity and migration. We then created maps comparing the past, present, and future projected burden of climatic hazards to global AD prevalence data. Data are lacking, especially from those regions most likely to experience more climatic hazards. We highlight gaps important for future research: understanding the synergistic impacts of climatic hazards on AD, long-term disease activity, the differential impact on vulnerable populations, and how basic mechanisms explain population-level trends.

Abstract
Treat-to-target (T2T) is a pragmatic therapeutic strategy being gradually introduced into dermatology after adoption in several other clinical areas. Atopic dermatitis (AD), one of the most common inflammatory skin diseases, may also benefit from this structured and practical therapeutic approach. We aimed to evaluate existing data regarding the T2T approach in dermatology, with a specific focus on AD, as well as the views of International Eczema Council (IEC) members on the potential application of a T2T approach to AD management. To do so, we systematically searched for peer-reviewed publications on the T2T approach for any skin disease in the PubMed and Scopus databases up to February 2022 and conducted a survey among IEC members regarding various components to potentially include in a T2T approach in AD. We identified 21 relevant T2T-related reports in dermatology, of which 14 were related to psoriasis, five to AD, one for juvenile dermatomyositis and one for urticaria. In the IEC member survey, respondents proposed treatable traits (with itch, disease severity and sleep problems getting the highest scores), relevant comorbidities (with asthma being selected most commonly, followed by anxiety and depression in adults), recommended specialists that should define the approach in AD (dermatologists, allergists and primary care physicians were most commonly selected in adults), and applicable assessment tools (both physician- and patient-reported), in both adult and paediatric patients, for potential future utilization of the T2T approach in AD. In conclusion, while the T2T approach may become a useful tool to simplify therapeutic goals and AD management, its foundation in AD is only starting to build. A multidisciplinary approach, including a wide range of stakeholders, including patients, is needed to further define the essential components needed to utilize T2T in AD.

Abstract
The Dermatology: 'Getting It Right the First Time' (GIRFT) Programme National Specialty Report recommended improving access to, and the quality of, paediatric dermatology services. Understanding referral patterns makes it easier to identify areas that can be improved. This study analysed 292 new referrals to a national care centre that provides secondary care to 50% of all Irish children. Results showed that 51% of new referrals could have been managed in primary care and 41% of new referrals were inappropriate, including 5.5% having no abnormal skin findings. These results indicate that up to 876 referrals could have been avoided over a 13-month period, freeing up resources and reducing wait times for cases more appropriate for a secondary and tertiary care centre. This would improve access for children, allowing them to be diagnosed at the right place and time, in alignment with GIRFT values.

Abstract
This study describes the findings from a cross-sectional survey of 206 general practitioners (GPs), investigates the factors affecting the referral process to secondary care and highlights challenges faced. The results showed that most GPs are interested in caring for children with skin diseases locally, given sufficient support and training. However, GPs reported challenges because of limited access to resources and advice, high demand on dermatology services, and the need for better collaboration between generalists and specialists. We suggest sharing knowledge and lessons learned from quality improvement exercises to create a more effective and connected care system.

Abstract
Atopic dermatitis (AD) is a heterogeneous, chronic, relapsing, inflammatory skin disease associated with considerable physical, psychological, and economic burden. The pathology of AD includes complex interactions involving abnormalities in immune and skin barrier genes, skin barrier disruption, immune dysregulation, microbiome disturbance, and other environmental factors. Many of the cytokines involved in AD pathology, including IL-4, IL-13, IL-22, IL-31, thymic stromal lymphopoietin, and IFN-γ, signal through the Janus kinase (JAK)-signal transducer and activation of transcription (STAT) pathway. The JAK family includes JAK1, JAK2, JAK3, and tyrosine kinase 2; the STAT family includes STAT1, STAT2, STAT3, STAT4, STAT5A/B, and STAT6. Activation of the JAK-STAT pathway has been implicated in the pathology of several immune-mediated inflammatory diseases, including AD. However, the exact mechanisms of JAK-STAT involvement in AD have not been fully characterized. This review aims to discuss current knowledge about the role of the JAK-STAT signaling pathway and, specifically, the role of JAK1 in the pathology and symptomology of AD.

Abstract
PURPOSE PIK3CA-related overgrowth spectrum (PROS) encompasses several rare conditions resulting from activating variants in PIK3CA. Alpelisib, a PI3Kα-selective inhibitor, targets the underlying etiology of PROS, offering a novel therapeutic approach to current management strategies. This study evaluated the safety and efficacy of alpelisib in pediatric and adult patients with PROS. METHODS EPIK-P1 (NCT04285723) was a non-interventional, retrospective chart review of 57 patients with PROS (≥2 years) treated with alpelisib through compassionate use. Patients had severe/life-threatening PROS-related conditions and confirmed PIK3CA pathogenic variant. The primary end point assessed patient response to treatment at Week 24 (6 months). RESULTS Twenty-four weeks (6 months) after treatment initiation, 12 of 32 (37.5%) patients with complete case records included in the analysis of the primary end point experienced a ≥20% reduction in target lesion(s) volume. Additional clinical benefit independent from lesion volume reduction was observed across the full study population. Adverse events (AEs) and treatment-related AEs were experienced by 82.5% (47/57) and 38.6% (22/57) of patients, respectively; the most common treatment-related AEs were hyperglycemia (12.3%) and aphthous ulcer (10.5%). No deaths occurred. CONCLUSION EPIK-P1 provides real-world evidence of alpelisib effectiveness and safety in patients with PROS and confirms PI3Kα as a valid therapeutic target for PROS symptom management.

Abstract
INTRODUCTION We explored patient satisfaction with baricitinib, an oral Janus kinase inhibitor, in patients with atopic dermatitis (AD) treated in routine clinical practice. METHODS Adults with moderate-to-severe AD treated with baricitinib in clinical practice for ≥4 weeks in France, Germany, and the UK completed a one-time online survey under market research methodologies. Treatment satisfaction was assessed using a Likert scale and abbreviated Treatment Satisfaction Questionnaire for Medication (TSQM-9). Patients reported demographic, disease, and treatment information. Data were analyzed descriptively. RESULTS The survey was completed by 170 patients with a mean age of 39.3 years (SD = 13.5), 59% (n = 101) were female. At baricitinib initiation, 79% rated their AD as "Severe", yet 28% reported body surface area (BSA) involvement ≥10%. Most were "Satisfied" or "Very satisfied" (76%/18%) with baricitinib, with high rates reported for controlling itch (36%/56%). Itch improvements were noted by 97% of patients. Some tapered/stopped (50%/32%) topical corticosteroid use, aligned with reported improvements on the patient global assessment and BSA. Mean TSQM-9 convenience score was 78.0 (SD = 14.0). CONCLUSIONS Satisfaction with itch control was particularly high, reflected in rates of improvement in itch since starting baricitinib. On the TSQM-9, the convenience score was the highest. Many patients tapered/stopped concomitant topicals, indicating baricitinib's effect in controlling AD symptoms.

Abstract
BACKGROUND Conventional systemic drugs are used to treat children and young people (CYP) with severe atopic dermatitis (AD) worldwide, but no robust randomized controlled trial (RCT) evidence exists regarding their efficacy and safety in this population. While novel therapies have expanded therapeutic options, their high cost means traditional agents remain important, especially in lower-resource settings. OBJECTIVES To compare the safety and efficacy of ciclosporin (CyA) with methotrexate (MTX) in CYP with severe AD in the TREatment of severe Atopic Eczema Trial (TREAT) trial. METHODS We conducted a parallel group assessor-blinded RCT in 13 UK and Irish centres. Eligible participants aged 2-16 years and unresponsive to potent topical treatment were randomized to either oral CyA (4 mg kg-1 daily) or MTX (0.4 mg kg-1 weekly) for 36 weeks and followed-up for 24 weeks. Co-primary outcomes were change from baseline to 12 weeks in Objective Severity Scoring of Atopic Dermatitis (o-SCORAD) and time to first significant flare (relapse) after treatment cessation. Secondary outcomes included change in quality of life (QoL) from baseline to 60 weeks; number of participant-reported flares following treatment cessation; proportion of participants achieving ≥ 50% improvement in Eczema Area and Severity Index (EASI 50) and ≥ 75% improvement in EASI (EASI 75); and stratification of outcomes by filaggrin status. RESULTS In total, 103 participants were randomized (May 2016-February 2019): 52 to CyA and 51 to MTX. CyA showed greater improvement in disease severity by 12 weeks [mean difference in o-SCORAD -5.69, 97.5% confidence interval (CI) -10.81 to -0.57 (P = 0.01)]. More participants achieved ≥ 50% improvement in o-SCORAD (o-SCORAD 50) at 12 weeks in the CyA arm vs. the MTX arm [odds ratio (OR) 2.60, 95% CI 1.23-5.49; P = 0.01]. By 60 weeks MTX was superior (OR 0.33, 95% CI 0.13-0.85; P = 0.02), a trend also seen for ≥ 75% improvement in o-SCORAD (o-SCORAD 75), EASI 50 and EASI 75. Participant-reported flares post-treatment were higher in the CyA arm (OR 3.22, 95% CI 0.42-6.01; P = 0.02). QoL improved with both treatments and was sustained after treatment cessation. Filaggrin status did not affect outcomes. The frequency of adverse events (AEs) was comparable between both treatments. Five (10%) participants on CyA and seven (14%) on MTX experienced a serious AE. CONCLUSIONS Both CyA and MTX proved effective in CYP with severe AD over 36 weeks. Participants who received CyA showed a more rapid response to treatment, while MTX induced more sustained disease control after discontinuation.

Abstract
Atopic dermatitis (AD) is a common inflammatory skin condition and prior genome-wide association studies (GWAS) have identified 71 associated loci. In the current study we conducted the largest AD GWAS to date (discovery N = 1,086,394, replication N = 3,604,027), combining previously reported cohorts with additional available data. We identified 81 loci (29 novel) in the European-only analysis (which all replicated in a separate European analysis) and 10 additional loci in the multi-ancestry analysis (3 novel). Eight variants from the multi-ancestry analysis replicated in at least one of the populations tested (European, Latino or African), while two may be specific to individuals of Japanese ancestry. AD loci showed enrichment for DNAse I hypersensitivity and eQTL associations in blood. At each locus we prioritised candidate genes by integrating multi-omic data. The implicated genes are predominantly in immune pathways of relevance to atopic inflammation and some offer drug repurposing opportunities.

Abstract
BACKGROUND Early detection of cognitive disability is challenging. We assessed the domain-specific, concurrent validity of the ages and stages questionnaire (ASQ-3) and the Bayley Scales of Infant and Toddler Development (BSID-III), and their ability to predict cognitive delay at school age. METHODS Within a longitudinal birth cohort study, a nested cohort of children was assessed using ASQ-3 and BSID-III at 24 months, and at 5 years using the Kaufmann brief IQ test (KBIT). RESULTS 278 children were assessed using BSID-III and ASQ-3 at 24-months; mean(SD) BW = 3445(506) grams, M:F ratio=52:48. ASQ-3 had reasonable predictive ability (AUROC, p value, sensitivity:specificity) of same domain delay for motor (0.630, p = 0.008, 50%:76.1%) and language (0.623, p = 0.010, 25%:99.5%) at 2 years, but poor ability to detect cognitive delay compared to BSID-III (0.587, p = 0.124, 20.7%/96.8%;). 204/278 children were assessed at 5 years. BSID-III language and cognition domains showed better correlation with verbal and nonverbal IQ (R = 0.435, p < 0.001 and 0.388, p < 0.001 respectively). Both assessments showed high specificity and low sensitivity for predicting delay at 5 years. CONCLUSIONS The ASQ-3 cognitive domain showed poor concurrent validity with BSID-III cognitive score. Both ASQ-3 and BSID-III at 2 years poorly predict cognitive delay at 5 years. IMPACT The ASQ-3 does not adequately detect cognitive delay or predict cognitive delay at 5 years, particularly for children with mild to moderate delay. The ASQ-3 shows reasonable concurrent validity with the motor and language subscales of the BSID-III. Neither early screening nor formal developmental testing demonstrated significant predictive validity to screen for cognitive delay at school age. This article highlights the need to analyse our existing model of using the ASQ-3 to screen for cognitive delay in children aged 2 years.

Abstract
AIMS First, population pharmacokinetic analyses were used to characterize upadacitinib pharmacokinetics in adolescent and adult participants with atopic dermatitis (AD) and to identify patient covariates that may impact upadacitinib pharmacokinetics. Second, the exposure-response relationship for upadacitinib with efficacy and safety endpoints, and the effect of age and concomitant use of topical corticosteroids (TCS) on the exposure-response relationship and dose selection for patients with AD were evaluated. METHODS A two-compartment model with combined first- and zero-order absorption adequately characterized the upadacitinib concentration-time profiles in 911 healthy volunteer adolescent and adult participants with AD who received upadacitinib 15 or 30 mg orally once daily (QD) as monotherapy or in combination with TCS for 16 weeks. Logistic regression models were developed to characterize the exposure-efficacy and safety relationships, and simulations were performed based on final exposure-response models to predict efficacy responses in participants with AD who received placebo or upadacitinib as monotherapy or in combination with TCS. RESULTS Upadacitinib exposures were comparable between adolescents and adults. Mild or moderate renal impairment was predicted to increase the upadacitinib area under the plasma concentration-time curve from time zero to 24 h after dosing (AUC24 ) approximately 12% and 25%, respectively, compared to participants with normal renal function. Female participants were predicted to have 20% higher AUC24 compared to male participants. Participants with AD were predicted to have 18% higher AUC24 compared to healthy participants. Simulated clinical efficacy responses showed added clinical efficacy benefit for all endpoints evaluated (8-14%) with the upadacitinib 30 mg once-daily regimen compared to 15 mg once-daily in both age groups. In participants receiving upadacitinib in combination with TCS, significant exposure-dependent increases in upadacitinib efficacy endpoints were observed. No significant effects of age or weight were identified in any of the exposure-response models. CONCLUSION The results of these analyses support the dose justification for upadacitinib in adult and adolescent patients with moderate to severe AD.

Abstract
Methotrexate (MTX) is a readily accessible drug, first used in 1948 and employed for a wide variety of indications since then. However, despite widespread off-label use, FDA labeling does not include approved indications for the use of MTX for many inflammatory skin diseases in pediatric patients, including morphea, psoriasis, atopic dermatitis, and alopecia areata, among others. Without published treatment guidelines, some clinicians may be hesitant to use MTX off-label, or uncomfortable prescribing MTX in this population. To address this unmet need, an expert consensus committee was convened to develop evidence- and consensus-based guidelines for use of MTX to treat pediatric inflammatory skin disease. Clinicians with experience and expertise in clinical research, drug development, and treating inflammatory skin disease in pediatric patients with MTX were recruited. Five committees were created based on major topic areas: (1) indications and contraindications, (2) dosing, (3) interactions with immunizations and medications, (4) adverse effects (potential for and management of), and (5) monitoring needs. Pertinent questions were generated and addressed by the relevant committee. The entire group participated in a modified Delphi process to establish agreement on recommendations for each question. The committee developed 46 evidence- and consensus-based recommendations, each with >70% agreement among members, across all five topics. These are presented in tables and text, along with a discussion of supporting literature, and level of evidence. These evidence- and consensus-based recommendations will support safe and effective use of MTX for the underserved population of pediatric patients who may benefit from this valuable, time-honored medication.

Abstract
BACKGROUND Skin barrier dysfunction is a key component of the pathogenesis of atopic dermatitis (AD). Recent research on barrier optimization to prevent AD has shown mixed results. The aim of this study was to assess the relationship between emollient bathing at 2 months and the trajectory of AD in the first 2 years of life in a large unselected observational birth cohort study. METHODS The Babies After SCOPE: Evaluating the Longitudinal Impact Using Neurological and Nutritional Endpoints Birth Cohort study enrolled 2183 infants. Variables extracted from the database related to early skincare, skin barrier function, parental history of atopy, and AD outcomes. Statistical analysis was performed to adjust for potential confounding variables. RESULTS One thousand five hundred five children had data on AD status available at 6, 12, and 24 months. Prevalence of AD was 18.6% at 6 months, 15.2% at 12 months, and 16.5% at 24 months. Adjusted for potential confounding variables, the odds of AD at any point were higher among infants who had emollient baths at 2 months (OR (95% CI): 2.41 (1.56 to 3.72), p < .001). Following multivariable analysis, the odds of AD were higher among infants who had both emollient baths and frequent emollient application at 2 months, compared with infants who had neither (OR (95% CI) at 6 months 1.74 (1.18-2.58), p = .038), (OR (95% CI) at 12 months 2.59 (1.69-3.94), p < .001), (OR (95% CI) at 24 months 1.87 (1.21-2.90), p = .009). CONCLUSION Early emollient bathing was associated with greater development of AD by 2 years of age in this population-based birth cohort study.

Abstract
INTRODUCTION Atopic dermatitis (AD) is a chronic inflammatory skin disorder with limited treatment options for adolescents with moderate-to-severe disease. Lebrikizumab, a monoclonal antibody targeting interleukin (IL)-13, demonstrated clinical benefit in previous Phase 3 trials: ADvocate1 (NCT04146363), ADvocate2 (NCT04178967), and ADhere (NCT04250337). We report 52-week safety and efficacy outcomes from ADore (NCT04250350), a Phase 3, open-label study of lebrikizumab in adolescent patients with moderate-to-severe AD. The primary endpoint was to describe the proportion of patients who discontinued from study treatment because of adverse events (AEs) through the last treatment visit. METHODS Adolescent patients (N = 206) (≥ 12 to < 18 years old, weighing ≥ 40 kg) with moderate-to-severe AD received subcutaneous lebrikizumab 500 mg loading doses at baseline and Week 2, followed by 250 mg every 2 weeks (Q2W) thereafter. Safety was monitored using reported AEs, AEs leading to treatment discontinuation, vital signs, growth assessments, and laboratory testing. Efficacy analyses included Eczema Area and Severity Index (EASI), Investigator's Global Assessment (IGA), Body Surface Area (BSA), (Children's) Dermatology Life Quality Index ((C)DLQI), and Patient-Reported Outcomes Measurement Information System (PROMIS) Anxiety, and PROMIS Depression. RESULTS 172 patients completed the treatment period. Low frequencies of SAEs (n = 5, 2.4%) and AEs leading to treatment discontinuation (n = 5, 2.4%) were reported. Overall, 134 patients (65%) reported at least one treatment-emergent AE (TEAE), most being mild or moderate in severity. In total, 62.6% achieved IGA (0,1) with ≥ 2-point improvement from baseline and 81.9% achieved EASI-75 by Week 52. The EASI mean percentage improvement from baseline to Week 52 was 86.0%. Mean BSA at baseline was 45.4%, decreasing to 8.4% by Week 52. Improvements in mean change from baseline (CFB) to Week 52 were observed in DLQI (baseline 12.3; CFB - 8.9), CDLQI (baseline 10.1; CFB - 6.5), PROMIS Anxiety (baseline 51.5; CFB - 6.3), and PROMIS Depression (baseline 49.3; CFB - 3.4) scores. CONCLUSIONS Lebrikizumab 250 mg Q2W had a safety profile consistent with previous trials and significantly improved AD symptoms and quality of life, with meaningful responses at Week 16 increasing by Week 52.

Abstract
To elaborate expert consensus patient pathways to guide patients and physicians toward efficient diagnostics and management of patients with venous malformations. Methods VASCERN-VASCA (https://vascern.eu/) is a European network of multidisciplinary centers for Vascular Anomalies. The Nominal Group Technique was used to establish the pathways. Two facilitators were identified: one to propose initial discussion points and draw the pathways, and another to chair the discussion. A dermatologist (AD) was chosen as first facilitator due to her specific clinical and research experience. The draft was subsequently discussed within VASCERN-VASCA monthly virtual meetings and annual face-to-face meetings. Results The Pathway starts from the clinical suspicion of a venous type malformation (VM) and lists the clinical characteristics to look for to support this suspicion. Strategies for subsequent imaging and histopathology are suggested. These aim to inform on the diagnosis and to separate the patients into 4 subtypes: (1) sporadic single VMs or (2) multifocal, (3) familial, multifocal, and (4) combined and/or syndromic VMs. The management of each type is detailed in subsequent pages of the pathway, which are color coded to identify sections on (1) clinical evaluations, (2) investigations, (3) treatments, and (4) associated genes. Actions relevant to all types are marked in separate boxes, including when imaging is recommended. When definite diagnoses have been reached, the pathway also points toward disease-specific additional investigations and recommendations for follow up. Options for management are discussed for each subtype, including conservative and invasive treatments, as well as novel molecular therapies. Conclusion The collaborative efforts of VASCERN-VASCA, a network of the 9 Expert Centers, has led to a consensus Diagnostic and Management Pathways for VMs to assist clinicians and patients. It also emphasizes the role of multidisciplinary expert centers in the management of VM patients. This pathway will become available on the VASCERN website (http://vascern.eu/).

Abstract
Importance Atopic dermatitis onset usually occurs in childhood. Persistence of disease into adolescence and adulthood is common. It is important to evaluate new treatment options in adolescents because of the high unmet need in this population. Objective To assess the efficacy and safety of upadacitinib to treat moderate-to-severe atopic dermatitis in adolescents. Design, Setting, and Participants Prespecified analysis of adolescents enrolled in 3 randomized, double-blind, placebo-controlled phase 3 clinical trials in more than 20 countries across Europe, North and South America, Oceania, the Middle East, and the Asia-Pacific region from July 2018 through December 2020. Participants were adolescents aged 12 to 17 years with moderate-to-severe atopic dermatitis. Data analysis was performed from April to August 2021. Interventions Patients were randomized (1:1:1) to once-daily oral upadacitinib 15 mg, upadacitinib 30 mg, or placebo alone (Measure Up 1 and Measure Up 2) or with topical corticosteroids (AD Up). Main Outcomes and Measures Safety and efficacy, including at least a 75% improvement in the Eczema Area and Severity Index from baseline and validated Investigator Global Assessment for Atopic Dermatitis score of 0 (clear) or 1 (almost clear) at week 16 (coprimary end points). Results A total of 552 adolescents (290 female; 262 male) were randomized. Mean (SD) age was 15.4 (1.8), 15.5 (1.7), and 15.3 (1.8) years for adolescents in Measure Up 1, Measure Up 2, and AD Up, respectively. In Measure Up 1, Measure Up 2, and AD Up, respectively, a greater proportion of adolescents (% [95% CI]) achieved at least 75% improvement in the Eczema Area and Severity Index at week 16 with upadacitinib 15 mg (73% [63%-84%], 69% [57%-81%], 63% [51%-76%]), and upadacitinib 30 mg (78% [68%-88%], 73% [62%-85%], 84% [75%-94%]), than with placebo (12% [4%-20%], 13% [5%-22%], 30% [19%-42%]; nominal P < .001 for all comparisons vs placebo). Similarly, a greater proportion of adolescents treated with upadacitinib achieved a validated Investigator Global Assessment for Atopic Dermatitis score of 0 or 1 at week 16 and improvements in quality of life with upadacitinib than with placebo. Upadacitinib was generally well tolerated in adolescents. Acne was the most common adverse event, and all acne events were mild or moderate. Conclusions and Relevance In this analysis of 3 randomized clinical trials, upadacitinib was an effective treatment for adolescents with moderate-to-severe atopic dermatitis, with an acceptable safety profile. Trial Registration ClinicalTrials.gov Identifiers: NCT03569293 (Measure Up 1), NCT03607422 (Measure Up 2), and NCT03568318 (AD Up).

Abstract
BACKGROUND Early prediction of therapeutic response can optimise treatment strategies in atopic dermatitis (AD). Baricitinib is approved for moderate-to-severe AD in Europe, Japan and other countries. AIM To identify early clinical improvements that reliably predict a later clinical response to baricitinib in adults with moderate-to-severe AD. METHODS Using data from one topical corticosteroid combination study and from two monotherapy studies (pooled), we calculated the sensitivity, specificity, and positive and negative predictive values (NPV) of predefined changes in single and combined clinical scores at weeks 2, 4 and 8 to predict clinical response at week 16. Clinical response was defined as Eczema Area and Severity Index (EASI) ≥75% improvement (EASI75), Itch Numeric Rating Scale (NRS) ≥4-point improvement (Itch NRS≥4), or a combination of both. RESULTS Composite predictors had higher predictive accuracy than single parameters. Sensitivities and NPVs for ≥50% EASI improvement (EASI50) or Itch NRS ≥3-point improvement (Itch NRS≥3), validated Investigator's Global Assessment of AD (vIGA-AD) score ≤2 or Itch NRS≥3 ranged from 87% to 97% and 68% to 100%, respectively, at week 4. The predictive accuracy for composite clinical outcomes at week 16 was highest at week 8 (sensitivity: 93%-100%; NPV: 80%-100%). At both weeks 4 and 8, EASI50 or Itch NRS≥3 had higher sensitivity and NPV than vIGA-AD score ≤2 or Itch NRS≥3. CONCLUSION Improvement in signs and symptoms early during treatment with baricitinib 4 mg once daily predicts clinical response at week 16, providing a tool for dermatologists when choosing treatment strategies with patients with moderate-to-severe AD.BREEZE-AD1 (NCT03334396); BREEZE-AD2 (NCT03334422); BREEZE-AD7 (NCT03733301).

Abstract
BACKGROUND Atopic dermatitis (AD) is characterized by microbial dysbiosis, immune dysregulation, and an impaired skin barrier. Microbial dysbiosis in AD involves a reduction in diversity primarily driven by an increased abundance of Staphylococcus aureus. Tralokinumab, an approved treatment for adults with moderate-to-severe AD, improves the skin barrier and immune abnormalities by specifically targeting the interleukin 13 cytokine, but its impact on the skin microbiome is unknown. OBJECTIVE To investigate how tralokinumab affects the skin microbiome by examining the lesional skin of adults with moderate-to-severe AD from the phase 3 ECZTRA 1 trial (NCT03131648). METHODS Microbiome profiling, S aureus abundance, and biomarker data were assessed in a subset of ECZTRA 1 participants (S aureus abundance at baseline and week 16; microbiome profiling at baseline, and week 8/16; and serum sampling before dose and week 4/8/16/28/52). RESULTS Tralokinumab treatment led to increased microbial diversity, reduced S aureus abundance, and increased abundance of the commensal coagulase-negative Staphylococci. LIMITATIONS Limitations include a lack of S aureus abundance data at week 8, sampling site variation between participants, and possible influence from concomitant systemic antiinfectives. CONCLUSION Our findings indicate specific targeting of the interleukin 13 cytokine with tralokinumab can directly and/or indirectly improve microbial dysbiosis seen in AD skin.

Abstract
BACKGROUND Protecting the skin barrier in early infancy may prevent atopic dermatitis (AD). We investigated if daily emollient use from birth to 2 months reduced AD incidence in high-risk infants at 12 months. METHODS This was a single-center, two-armed, investigator-blinded, randomized controlled clinical trial (NCT03871998). Term infants identified as high risk for AD (parental history of AD, asthma or allergic rhinitis) were recruited within 4 days of birth and randomised 1:1 to either twice-daily emollient application for the first 8 weeks of life (intervention group), using an emollient specifically formulated for very dry, AD-prone skin, or to standard routine skin care (control group). The primary outcome was cumulative AD incidence at 12 months. AD <6 months was diagnosed based on clinical presence of AD. The UK Working Party Diagnostic Criteria were applied when diagnosing AD between 6 and 12 months. RESULTS Three hundred twenty-one were randomised (161 intervention and 160 control), with 61 withdrawals (41 intervention, 20 control). The cumulative incidence of AD at 12 months was 32.8% in the intervention group vs. 46.4% in the control group, p = 0.036 [Relative risk (95%CI): 0.707 (0.516, 0.965)]. One infant in the intervention group was withdrawn from the study following development of a rash that had a potential relationship with the emollient. There was no significant difference in the incidence of skin infections between the intervention and control groups during the intervention period (5.0% vs. 5.7%, p > 0.05). CONCLUSIONS This study has demonstrated that early initiation of daily specialized emollient use until 2 months reduces the incidence of AD in the first year of life in high-risk infants.

Abstract
BACKGROUND Lebrikizumab, a high-affinity IgG4 monoclonal antibody targeting interleukin-13, prevents the formation of the interleukin-4Rα-interleukin-13Rα1 heterodimer receptor signaling complex. METHODS We conducted two identically designed, 52-week, randomized, double-blind, placebo-controlled, phase 3 trials; both trials included a 16-week induction period and a 36-week maintenance period. Eligible patients with moderate-to-severe atopic dermatitis (adults [≥18 years of age] and adolescents [12 to <18 years of age, weighing ≥40 kg]) were randomly assigned in a 2:1 ratio to receive either lebrikizumab at a dose of 250 mg (loading dose of 500 mg at baseline and week 2) or placebo, administered subcutaneously every 2 weeks. Outcomes for the induction period were assessed up to 16 weeks and are included in this report. The primary outcome was an Investigator's Global Assessment (IGA) score of 0 or 1 (indicating clear or almost clear skin; range, 0 to 4 [severe disease]) with a reduction (indicating improvement) of at least 2 points from baseline at week 16. Secondary outcomes included a 75% improvement in the Eczema Area and Severity Index score (EASI-75 response) and assessments of itch and of itch interference with sleep. Safety was also assessed. RESULTS In trial 1, the primary outcome was met in 43.1% of 283 patients in the lebrikizumab group and in 12.7% of 141 patients in the placebo group (P<0.001); an EASI-75 response occurred in 58.8% and 16.2%, respectively (P<0.001). In trial 2, the primary outcome was met in 33.2% of 281 patients in the lebrikizumab group and in 10.8% of 146 patients in the placebo group (P<0.001); an EASI-75 response occurred in 52.1% and 18.1%, respectively (P<0.001). Measures of itch and itch interference with sleep indicated improvement with lebrikizumab therapy. The incidence of conjunctivitis was higher among patients who received lebrikizumab than among those who received placebo. Most adverse events during the induction period were mild or moderate in severity and did not lead to trial discontinuation. CONCLUSIONS In the induction period of two phase 3 trials, 16 weeks of treatment with lebrikizumab was effective in adolescents and adults with moderate-to-severe atopic dermatitis.

Abstract
Importance Erythrodermic atopic dermatitis (AD) is a severe AD subtype defined by extensive skin involvement, leading to complications and sometimes hospitalization. Objective To assess dupilumab's efficacy and safety in patients with erythrodermic AD in clinical trials. Design, Setting, and Participants This post hoc analysis included patients enrolled in 6 multicenter, multinational, randomized, double-blind, placebo-controlled trials. Patients included in this analysis met erythrodermic AD criteria of 90% or greater body surface area (BSA) affected by AD and Global Individual Sign Score for erythema of 1 or higher. Data analyses for this post hoc analysis were conducted between March 5, 2019, and October 24, 2020. Interventions Dupilumab once weekly or every 2 weeks, or placebo, either as monotherapy or with concomitant topical corticosteroids (TCS). Main Outcomes and Measures Efficacy (BSA, Eczema Area and Severity Index [EASI] score, Peak Pruritus Numerical Rating Scale [PP-NRS] score), changes in serum biomarkers (thymus and activation-regulated chemokine, total immunoglobulin E, lactate dehydrogenase), and safety (incidence of adverse events) at week 16. Data were pooled within each regimen; monotherapy and concomitant TCS results are shown separately. Results Of 3075 randomized patients, 209 met criteria for erythrodermic AD at baseline, with the median age being 31 and 39 years in the monotherapy and concomitant TCS trials, respectively, similar to the overall populations (34 and 36 years, respectively); 71.3% (n = 97) and 74.0% (n = 54) of patients, respectively, were male (compared with 58.7% and 60.6% in the overall populations). In patients with erythrodermic AD, dupilumab once weekly and every 2 weeks vs placebo significantly improved percentage of BSA affected by AD (least squares mean percent change [SE]) with monotherapy (-42.0% [7.7%] and -39.9% [6.5%] vs -17.2% [11.0%]; P = .03) and concomitant TCS (-63.2% [6.7%] and -56.1% [9.1%] vs -14.5% [7.3%]; P < .001); EASI score with monotherapy (-58.5% [9.0%] and -58.3% [7.9%] vs -22.3% [12.4%]; P = .004 and P = .003, respectively) and concomitant TCS (-78.9% [7.8%] and -70.6% [10.1%] vs 19.3% [8.2%]; P < .001); and PP-NRS score in monotherapy (-45.9% [7.8%] and -33.9% [6.6%] vs -0.6% [9.4%]; P < .001) and concomitant therapy (-53.0% [8.1%] and -55.7% [10.8%] vs -26.0% [8.8%]; P = .006 and P = .01, respectively). Nominally statistically significant improvement was seen as early as week 1 (EASI and PP-NRS scores with monotherapy). Biomarker levels were significantly reduced vs placebo. The most frequent adverse events in dupilumab-treated patients were injection-site reaction, conjunctivitis, and nasopharyngitis. Conclusions and Relevance In this post hoc analysis of 6 randomized clinical trials, treatment with dupilumab resulted in rapid, sustained improvements in AD signs and symptoms with acceptable safety in patients with erythrodermic AD, similar to those in the trials' overall patient population.

Abstract
To enhance the understanding of molecular mechanisms and mine previously unidentified biomarkers of pediatric atopic dermatitis, PBMC gene expression profiles were generated by RNA sequencing in infants with atopic dermatitis and age-matched controls. A total of 178 significantly differentially expressed genes (DEGs) (115 upregulations and 63 downregulations) were seen, compared with those in healthy controls. The DEGs identified included IL1β, TNF, TREM1, IL18R1, and IL18RAP. DEGs were validated by real-time RT- qPCR in a larger number of samples from PBMCs of infants with atopic dermatitis aged <12 months. Using the DAVID (Database for Annotation, Visualization and Integrated Discovery) database, functional and pathway enrichment analyses of DEGs were performed. Gene ontology enrichment analysis showed that DEGs were associated with immune responses, inflammatory responses, regulation of immune responses, and platelet activation. Pathway analysis indicated that DEGs were enriched in cytokine‒cytokine receptor interaction, immunoregulatory interactions between lymphoid and nonlymphoid cells, hematopoietic cell lineage, phosphoinositide 3-kinase‒protein kinase B signaling pathway, NK cell‒mediated cytotoxicity, and platelet activation. Furthermore, the protein‒protein interaction network was predicted using the STRING (Search Tool for the Retrieval of Interacting Genes/Proteins) database and visualized with Cytoscape software. Finally, on the basis of the protein‒protein interaction network, 18 hub genes were selected, and two significant modules were obtained. In conclusion, this study sheds light on the molecular mechanisms of pediatric atopic dermatitis and may provide diagnostic biomarkers and therapeutic targets.

Abstract
Background Few data exist on differences in treatment effectiveness and safety in atopic dermatitis patients of different skin types. Objective To investigate treatment outcomes of dupilumab, methotrexate, and ciclosporin, and morphological phenotypes in atopic dermatitis patients, stratified by Fitzpatrick skin type. Methods In an observational prospective cohort study, pooling data from the Dutch TREAT (TREatment of ATopic eczema) NL (treatregister.nl) and UK-Irish A-STAR (Atopic eczema Systemic TherApy Register; astar-register.org) registries, data on morphological phenotypes and treatment outcomes were investigated. Results A total of 235 patients were included (light skin types [LST]: Fitzpatrick skin type 1-3, n = 156 [Ethnicity, White: 94.2%]; dark skin types [DST]: skin type 4-6, n = 68 [Black African/Afro-Caribbean: 25%, South-Asian: 26.5%, and Hispanics: 0%]). DST were younger (19.5 vs 29.0 years; P < .001), more often had follicular eczema (22.1% vs 2.6%; P < .001), higher baseline Eczema Area and Severity Index (EASI) scores (20.1 vs 14.9; P = .009), less allergic contact dermatitis (30.9% vs 47.4%; P = .03), and less previous phototherapy use (39.7% vs 59.0%; P = .008). When comparing DST and LST corrected for covariates including baseline EASI, DST showed greater mean EASI reduction between baseline and 6 months with only dupilumab (16.7 vs 9.7; adjusted P = .032). No differences were found for adverse events for any treatments (P > .05). Limitations Unblinded, non-randomized. Conclusion Atopic dermatitis differs in several characteristics between LST and DST. Skin type may influence treatment effectiveness of dupilumab.

Abstract
OBJECTIVE To evaluate the long-term safety profile for upadacitinib across rheumatoid arthritis (RA), psoriatic arthritis (PsA), ankylosing spondylitis (AS) and atopic dermatitis (AD). METHODS Safety data from clinical trials of upadacitinib 15 mg and upadacitinib 30 mg (AD only) for treating RA, PsA, AS and AD as of 30 June 2021 were analysed; some RA and PsA studies included adalimumab and methotrexate as active comparators. Treatment-emergent adverse events (TEAEs) were presented by disease as exposure-adjusted event rates per 100 patient years (E/100 PY). RESULTS The analysis included 6991 patients (RA, n=3209; PsA, n=907; AS, n=182; AD, n=2693) who received at least one dose of upadacitinib, representing 15 425 PY of exposure (maximum duration 2.75-5.45 years) across diseases. Rates (E/100 PY) of any TEAE (205.5-278.1) and TEAE leading to discontinuation (4.5-5.4) were similar across diseases; serious TEAEs were numerically higher in patients with RA and PsA. Rates of herpes zoster (1.6-3.6), non-melanoma skin cancer (0-0.8) and elevations in creatine phosphokinase levels (4.4-7.9) were higher with upadacitinib than with active comparators in the RA and PsA populations. Deaths (0-0.8), serious infections (0-3.9), major adverse cardiovascular events (0-0.4), venous thromboembolism (<0.1-0.4) and malignancies (0.3-1.4) were observed, with rates generally lowest in AS and AD. Increased rates of acne were observed in patients with AD only. CONCLUSIONS Findings from this analysis demonstrate that upadacitinib is generally well tolerated with observed differences in safety profiles likely reflective of varying patient characteristics across RA, PsA, AS and AD populations.

Abstract
BACKGROUND Postzygotic activating PIK3CA variants cause several phenotypes within the PIK3CA-related overgrowth spectrum (PROS). Variant strength, mosaicism level, specific tissue involvement and overlapping disorders are responsible for disease heterogeneity. We explored these factors in 150 novel patients and in an expanded cohort of 1007 PIK3CA-mutated patients, analysing our new data with previous literature to give a comprehensive picture. METHODS We performed ultradeep targeted next-generation sequencing (NGS) on DNA from skin biopsy, buccal swab or blood using a panel including phosphatidylinositol 3-kinase/AKT/mammalian target of rapamycin pathway genes and GNAQ, GNA11, RASA1 and TEK. Additionally, 914 patients previously reported were systematically reviewed. RESULTS 93 of our 150 patients had PIK3CA pathogenetic variants. The merged PROS cohort showed that PIK3CA variants span thorough all gene domains, some were exclusively associated with specific PROS phenotypes: weakly activating variants were associated with central nervous system (CNS) involvement, and strongly activating variants with extra-CNS phenotypes. Among the 57 with a wild-type PIK3CA allele, 11 patients with overgrowth and vascular malformations overlapping PROS had variants in GNAQ, GNA11, RASA1 or TEK. CONCLUSION We confirm that (1) molecular diagnostic yield increases when multiple tissues are tested and by enriching NGS panels with genes of overlapping 'vascular' phenotypes; (2) strongly activating PIK3CA variants are found in affected tissue, rarely in blood: conversely, weakly activating mutations more common in blood; (3) weakly activating variants correlate with CNS involvement, strong variants are more common in cases without; (4) patients with vascular malformations overlapping those of PROS can harbour variants in genes other than PIK3CA.

Abstract
Abstract
Children with atopic dermatitis (AD) are at risk for low bone mineral density (BMD), which is associated with an increased prevalence of osteopenia, osteoporosis, and fracture risk.1,2 Factors such as restricted nutrition, vitamin D deficiency, poor sleep and corticosteroid use contribute to lower bone alkaline phosphatase (BALP) levels, a marker of bone mineralization, seen in children with moderate-to-severe AD compared with healthy children.3 A major determinant for the lifetime risk of fractures and osteoporosis is the magnitude of peak bone mass achieved during prepubescent years. Low BALP and BMD in children with moderate-to-severe AD could contribute to a higher prevalence of osteopenia and osteoporosis. The objective of this analysis is to report the impact of dupilumab treatment on markers of bone formation in children aged ≥ 6 to < 12 years with moderate-to-severe AD. The analysis was performed retrospectively on sera from participants in LIBERTY AD PEDS (NCT03345914) and LIBERTY AD PED-OLE (NCT02612454). In LIBERTY AD PEDS, a double-blind, 16-week, phase 3 trial, children aged 6 to < 12 years were randomized 1 : 1 : 1 to 300 mg dupilumab every 4 weeks (300 mg q4w), a weight-based regimen of dupilumab every 2 weeks (100 mg q2w for patients with baseline weight <30 kg, and 200 mg q2w for those with baseline weight ≥30 kg), or placebo; with concomitant medium-potency topical corticosteroids (TCS). After the initial 16-week trial, children aged 6 to <12 years were enrolled in the open-label extension study LIBERTY AD PED-OLE. Patients received dupilumab 300 mg q4w, which could be titrated up in case of inadequate clinical response at week 16 (200 mg q2w for patients with baseline weight <60 kg, and 300 mg q2w for those with baseline weight ≥60 kg); with concomitant medium-potency TCS. Bone biomarkers including BALP, procollagen type 1 N-terminal propeptide, C-terminal crosslinking telopeptide of type 1 collagen, osteocalcin, and insulin-like growth factor 1 were analysed at baseline, 8, 12, 16 and BALP only at 52 weeks. Dupilumab treatment led to a rapid and significant increase in geometric mean (standard error) levels of BALP in children with moderate-to-severe AD at 16 weeks compared with patients in the placebo group (77.7(1.02) μgL−1 vs. 65.0(1.04) μgL−1; P < 0.0001). As well as a rapid and significant increase in BALP levels in children from the placebo group once they joined the OLE trial. BALP levels increased over 52 weeks in all treated children, reaching a level of 78–84 μgL−1 which constitutes a significant improvement compared with baseline, and is comparable to healthy reference intervals. An increasing trend from baseline to 16 weeks of dupilumab treatment was observed for other biomarkers, however, there was a limited number of data points due to insufficient volumes of serum available for analysis. These placebo-controlled results show, for the first time, a rapid and significant increase in BALP, and a possible trend in other biomarkers, in children with AD during treatment with dupilumab. These results suggest increased bone mineralization during the treatment period.

Abstract
INTRODUCTION Ichthyoses comprise a heterogenous group of rare genetic skin disorders that involves the entire skin surface, often with additional syndromic features, and pose many clinical challenges. Without curative intervention, the mainstay of life-long symptom management is supportive in nature and can remain the responsibility of the caregiver. Although impact on the wider family is considered an important outcome of policies and services, there is a lack of caregiver consensus on what outcome domains to measure to fully assess the impact of ichthyosis on the patient and the caregiver. This project aims to identify a set of core outcome domains towards a core outcome set for ichthyosis that can measure all relevant concepts of ichthyosis in clinical practice, service delivery and research. METHODS AND ANALYSIS Following the COMET (Core Outcome Measures in Effectiveness Trials) initiative, this project will employ a mixed-method study design which was developed using public and patient involvement and an international multidisciplinary expert group (clinical experts, patients and their representatives, policymakers, researchers and service providers). Experts by experience, or caregivers, will be recruited through online ichthyosis support groups. Phase one will focus on item generation and involve: (1) a systematic literature review, (2) a multimethods international qualitative study with ichthyosis caregivers and (3) co-development of items for an e-survey. Phase two, item refinement, will employ a novel four-pronged consensus approach: (1) an e-Delphi survey, (2) statistical analysis of e-Delphi survey results, (3) online qualitative feedback and (4) an online consensus discussion. All methodological considerations will be clearly linked with each Core Outcome Set-STAndards for Developing recommendation. ETHICS AND DISSEMINATION Research Ethics Committee approval obtained from the School of Psychology, Ulster University (UK)(Ref:REC/20/0004). Results will be presented in published international peer-reviewed journals, at scientific meetings and support groups. REGISTRATION COMET database (January 2019).

Abstract
BACKGROUND Upadacitinib is a selective reversible Janus kinase (JAK) inhibitor with established efficacy in moderate-to-severe atopic dermatitis (AD). OBJECTIVE We evaluated the safety of upadacitinib in patients with moderate-to-severe AD. METHODS Integrated safety data from the 16-week placebo-controlled periods of 1 phase 2b and 3 ongoing phase 3 studies (16 weeks) and longer-term safety data from patients receiving upadacitinib during the blinded extension periods of the three phase 3 studies were analyzed (all upadacitinib exposure). Treatment-emergent adverse events (TEAEs) were presented as exposure-adjusted rates per 100 patient-years (PY). RESULTS Safety results were similar between the 16-week and all upadacitinib exposure groups. The latter group included 2485 patients (333 adolescents), receiving upadacitinib 15 mg (n = 1239) or 30 mg (n = 1246) for a mean duration of approximately 1 year. Upadacitinib was well tolerated by both adults and adolescents. TEAEs and discontinuation due to AEs were reported more frequently in patients receiving 30 mg upadacitinib (respectively, 311.9 and 5.7 events per 100 PY) versus 15 mg (respectively, 274.6 and 4.4 events per 100 PY). Serious adverse event rates (15/30 mg, 7.1/7.7 events per 100 PY) were similar in both groups. Acne was the most frequently reported adverse event (15/30 mg, 13.3/20.2 events per 100 PY). Serious infection rates were similar across treatment groups. Adjudicated major adverse cardiovascular event and venous thromboembolic event rates were ≤0.1 events per 100 PY. Rates of malignant neoplasms were within the expected range for the general population. CONCLUSIONS Upadacitinib was well tolerated, and no new important safety risks were observed among adults and adolescents with moderate-to-severe AD treated for approximately 1 year compared to the known safety profile of upadacitinib.

Abstract
BACKGROUND Atopic dermatitis (AD) has a strong genetic basis. The objective of this study was to assess the association between parental atopy and AD development by 2 years. METHODS A secondary data analysis of the BASELINE Birth Cohort study was performed (n = 2183). Parental atopy was self-reported at 2 months. Infants were examined for AD by trained health care professionals at 6, 12, and 24 months. Variables extracted from the database related to skin barrier function, early skincare, parental atopy, and AD. Statistical analysis adjusted for potential confounding variables. RESULTS Complete data on AD status were available for 1505 children at 6, 12, and 24 months. Prevalence of AD was 18.6% at 6 months, 15.2% at 12 months, and 16.5% at 24 months. Adjusted odds ratios (95% CIs) following multivariable analysis were 1.57 (1.09-2.25) at 6 months and 1.66 (1.12-2.46) at 12 months for maternal AD; 1.90 (1.28-2.83) at 6 months and 1.85 (1.20-2.85) at 24 months for paternal AD; 1.76 (1.21-2.56) at 6 months and 1.75 (1.16-2.63) at 12 months for maternal asthma; and 1.70 (1.19-2.45) at 6 months, 1.86 (1.26-2.76) at 12 months, and 1.99 (1.34-2.97) at 24 months for paternal asthma. Parental rhinitis was only associated with AD with maternal rhinitis at 24 months (aOR (95% CI): 1.79 (1.15-2.80)). CONCLUSION Parental AD and asthma were associated with increased risk of objectively diagnosed AD in offspring in this contemporary cohort.

Abstract
BACKGROUND Atopic dermatitis (AD) is the most common chronic inflammatory skin condition in childhood. Most (50-60%) children with AD report sleep disturbance, which is secondary to itch, dry skin, inflammation, and abnormal circadian rhythm. Sleep is essential for brain development, learning, and growth. Sleep disruption in early life is associated with cognitive and psychological dysfunction in later life. The aim of this study is to describe in detail the sleep architecture of infants with early-onset atopic dermatitis (AD), compared to controls, by using EEG polysomnography, sleep actigraphy, and parental reporting. METHODS This observational study will recruit six- to eight-month old infants with moderate to severe AD and age-matched control infants who do not have AD. At six-eight months diurnal sleep electroencephalography and polysomnography will be performed in our research center. Nocturnal sleep actigraphy will be performed at home for five consecutive nights at six-eight months and 12 months. Between six and 12 months, monthly questionnaires will capture data on quantitative sleep and parental sleep. Skin barrier and immune profiles will be captured at six-eight and 12 months. AD will be assessed using standardized severity assessment tools and treated according to protocol. A neurodevelopmental assessment will be performed at 18 months to assess cognition and behaviour. An estimated sample size of 50 participants in each group is required to power the primary outcome of disturbed macrostructure of sleep and secondary outcomes of disturbed microstructure of sleep, and disturbed parental sleep, assuming an attrition rate of 60%. Potential confounding factors which will be controlled for in the data analysis will include parental educational level, parental depression, feeding practice, and number of siblings. DISCUSSION This study will provide a rich analysis of sleep in infants with AD in the first year of life using detailed electroencephalography, novel actigraphy techniques, and longitudinal parent-reported data. It may provide guidance on the optimal treatment of AD to prevent or reduce sleep disruption. TRIAL REGISTRATION clinicaltrials.gov NCT05031754 , retrospectively registered on September 2nd, 2021.

Abstract
e18694 Background: PIK3CA mutations seen in cancer also drive other disease, exciting interest in repurposing oncology therapies for non-oncology indications. ALP is a PI3Kα inhibitor approved for HR+, HER2– ABC with fulvestrant. Clinical benefit of ALP in PROS, a group of rare phenotypically varied disorders driven by mutations in PIK3CA, was found in 19 pts (Venot, 2018). EPIK-P1 (NCT04285723) collected real-world data (RWD) to confirm ALP’s efficacy and safety in PROS. In the primary analysis of the primary endpoint, 12/32 pts (37.5%; 95% CI, 21.1-56.3%) with complete cases responded (≥20% reduction in the sum of target lesion volume from index/treatment [tx] start). Adverse events (AEs) and tx-related AEs were experienced by 82.5% (n = 47) and 38.6% (n = 22) of pts, respectively. The most common tx-related AE was hyperglycemia (n = 7, 12.3%). No deaths were reported (Canaud, ESMO 2021 LBA23). Methods: EPIK-P1 retrospectively abstracted data from the medical charts of pts aged ≥2 y with PROS experiencing severe/life-threatening conditions receiving ALP under compassionate use. Secondary endpoints evaluated safety and clinical benefit. Results: 57 pts were enrolled and followed for a median of 18.1 mo. No pt in the primary analysis (complete cases, n = 32) had progressive disease (PD) at wk 24; 1 pt discontinued ALP prior to wk 24 and considered a nonresponder. Of the 12 responders, median duration of response (time from first documented response to first documented PD or death due to any cause) was not estimable. Median time to censoring (date of last adequate lesion assessment) was 63.3 wk (̃14.6 mo; range, 1 d-186.7 wk); 2 pts had no further imaging assessments, 10 pts did not experience an event and tx was ongoing at data cutoff. Time to censoring was > 6 mo in 7 pts and > 12 mo in 6 pts. 11/20 nonresponders (55.0%) had target lesion volume reduction ranging from 0.7 to 19.6%. No pt required rescue surgery between index and wk 24. At index all pts reported ≥1 PROS-related symptom (eg, fatigue, pain). At wk 24, 82.5% (n = 47) reported symptom improvement regardless of primary analysis response status (responders, 10/12, 83.3%; nonresponders, 16/20, 80.0%). Median daily dose was 50 mg for pediatrics and 250 mg for adults. Dose reductions or interruptions were experienced by 15.8% of pts (n = 9); AEs led to dose reductions and interruptions in 3.5% (n = 2) and 10.5% (n = 6) of pts, respectively. 52 pts (91.2%) remained on tx at data cutoff; among 5 pts (8.8%) who discontinued, pt decision was the leading cause. Conclusions: RWD from EPIK-P1 demonstrate alpelisib as well tolerated, providing clinical benefit to pts with PROS regardless of response status in the primary analysis of the primary endpoint. Continued RWD collection complements planned prospective, randomized, placebo-controlled studies, facilitating access to alpelisib as an emerging pharmacologic option for PROS.

Abstract
Several clinical trials of Staphylococcus aureus (S. aureus)‒targeted therapies for atopic dermatitis (AD) have shown conflicting results about whether they improve AD severity scores. This study performs a model-based meta-analysis to investigate the possible causes of these conflicting results and suggests how to improve the efficacies of S. aureus‒targeted therapies. We developed a mathematical model that describes systems-level AD pathogenesis involving dynamic interactions between S. aureus and coagulase-negative Staphylococcus (CoNS). Our model simulation reproduced the clinically observed detrimental effects of the application of S. hominis A9 and flucloxacillin on AD severity and showed that these effects disappeared if the bactericidal activity against CoNS was removed. A hypothetical (modeled) eradication of S. aureus by 3.0 log10 colony-forming unit per cm2 without killing CoNS achieved Eczema Area and Severity Index 75 comparable with that of dupilumab. This efficacy was potentiated if dupilumab was administered in conjunction with S. aureus eradication (Eczema Area and Severity Index 75 at week 16) (S. aureus eradication: 66.7%, dupilumab 61.6% and combination 87.8%). The improved efficacy was also seen for virtual dupilumab poor responders. Our model simulation suggests that killing CoNS worsens AD severity and that S. aureus‒specific eradication without killing CoNS could be effective for patients with AD, including dupilumab poor responders. This study will contribute to designing promising S. aureus‒targeted therapy.

Abstract
BACKGROUND Several biologics for atopic dermatitis (AD) have demonstrated good efficacy in clinical trials, but with a substantial proportion of patients being identified as poor responders. This study aims to understand the pathophysiological backgrounds of patient variability in drug response, especially for dupilumab, and to identify promising drug targets in dupilumab poor responders. METHODS We conducted model-based meta-analysis of recent clinical trials of AD biologics and developed a mathematical model that reproduces reported clinical efficacies for nine biological drugs (dupilumab, lebrikizumab, tralokinumab, secukinumab, fezakinumab, nemolizumab, tezepelumab, GBR 830, and recombinant interferon-gamma) by describing system-level AD pathogenesis. Using this model, we simulated the clinical efficacy of hypothetical therapies on virtual patients. RESULTS Our model reproduced reported time courses of %improved EASI and EASI-75 of the nine drugs. The global sensitivity analysis and model simulation indicated the baseline level of IL-13 could stratify dupilumab good responders. Model simulation on the efficacies of hypothetical therapies revealed that simultaneous inhibition of IL-13 and IL-22 was effective, whereas application of the nine biologic drugs was ineffective, for dupilumab poor responders (EASI-75 at 24 weeks: 21.6% vs. max. 1.9%). CONCLUSION Our model identified IL-13 as a potential predictive biomarker to stratify dupilumab good responders, and simultaneous inhibition of IL-13 and IL-22 as a promising drug therapy for dupilumab poor responders. This model will serve as a computational platform for model-informed drug development for precision medicine, as it allows evaluation of the effects of new potential drug targets and the mechanisms behind patient variability in drug response.

Abstract
Background Atopic dermatitis (AD) is characterized by immune dysregulations and an impaired skin barrier, including abnormalities in lipid organization. In the stratum corneum (SC), β‐glucocerebrosidase (GBA) mediates transformation of glucosylceramide (GlcCER) into ceramide (CER) and cholesterol into glucosylcholesterol (GlcChol). Alteration in GBA activity might contribute to skin barrier defects in AD. Objectives To investigate GBA activity in the SC of children with AD before and after topical corticosteroid therapy and to compare it with healthy controls; to determine SC levels of GlcCER‐ and CER‐containing hydroxysphingosine base (GlcCER[H] and CER[H], respectively) and GlcChol; and to relate them to disease severity, skin barrier function and the local cytokine milieu. Methods Lipid markers and cytokines of innate, T helper 1 and T helper 2 immunity were determined in SC collected from healthy children and from clinically unaffected skin of children with AD, before and after 6 weeks of therapy with topical corticosteroids. AD severity was assessed by Scoring Atopic Dermatitis and skin barrier function by transepidermal water loss (TEWL). Results Baseline GBA activity and GlcChol levels were increased in children with AD but declined after therapy. CER[H] levels and the CER[H] to GlcCER[H] ratio were increased in AD. GBA activity and GlcChol correlated with TEWL and levels of multiple cytokines, especially interleukin‐1α and interleukin‐18. GlcChol was strongly associated with disease severity. Conclusions We show increased GBA activity and levels of GlcChol in AD. Our data suggest an important role of inflammation in disturbed lipid processing. GBA activity or GlcChol might be useful biomarkers in the monitoring of therapeutic responses in AD. What is already known about this topic?Patients with atopic dermatitis (AD) have a reduced skin barrier, mainly caused by altered lipid organization. The mechanisms underlying these lipid anomalies are not fully understood but likely reflect both genetic abnormalities in AD skin and the local cutaneous inflammatory environment.
What does this study add?We show increased activity of the ceramide‐generating enzyme β‐glucocerebrosidase in AD. Activity of this enzyme was correlated with the local cytokine milieu and declined after local corticosteroid therapy. We show that glucosylcholesterol levels in the stratum corneum are increased in AD. The function of glucosylcholesterol and the physiological consequences of increased levels are not clear yet; however, its levels were strongly correlated with skin barrier function: high transepidermal water loss strongly correlated with high levels of glucosylcholesterol.
What is the translational message?Correction of cutaneous inflammation largely restores alterations in lipid metabolism in the stratum corneum of infants with AD.

Abstract
The recent advent of numerous clinical trials for the treatment of moderate-to-severe atopic dermatitis has led to new and emerging therapeutic options for this chronic inflammatory skin disease. With this rapid development has come a lack of consistency in study designs, trial conduct, and statistical analyses. Healthcare providers are challenged to interpret how variations in study parameters may influence clinical trial results. Based on literature review and our experience as clinical trialists, we compiled a list of 22 key study parameters of contemporary clinical trials in moderate-to-severe atopic dermatitis and ranked the top study parameters that may have a significant effect on efficacy results. The top parameters included study comparators, rules for rescue treatment, washout periods for topical and systemic treatments, inclusion criteria such as disease severity by Eczema Area and Severity Index and/or Investigator Global Assessment scores, and the duration of the screening period. We describe considerations for these key parameters, with a focus on between-parameter interactions and effect on efficacy results. This may serve to inform the interpretation of atopic dermatitis clinical trials and raise the profile of the need to harmonize the clinical trial design. Atopic dermatitis (AD) is a skin disease characterized by red, itchy skin that is highly burdensome for patients. Patients with moderate-to-severe disease have large, inflamed skin areas with frequent itching. Recently, the number of clinical trials for drugs that treat moderate-to-severe AD has rapidly increased, with differences in how these trials are designed. There is a need for healthcare providers examining results from different clinical trials to understand how trial design factors might influence study outcomes. In this article, we identify key trial design factors that impact study outcomes, detail how these factors can impact clinical trial results, and explore how these factors interact with one another to affect study outcomes. The five most important design factors, as determined via author surveys, were study comparators (a placebo and/or another drug to which the drug being studied is compared); the rules for the use of rescue treatment (a form of treatment given if an enrolled participant has uncontrolled AD symptoms); washout periods (the time before the trial when previous treatments are stopped to allow them to be cleared from a patient’s system); inclusion criteria (that determine which participants are included); and the length of the screening period (the time when patients are assessed to determine if they qualify for participation). By understanding how these key trial design factors impact on study outcomes, healthcare providers may be equipped to better interpret different AD clinical trials. This work also emphasizes the value of harmonizing the AD clinical trial design.
