Abstract
Atopic dermatitis (AD) is a prevalent inflammatory skin condition impacting both children and adults globally, with a prevalence of 15-30%. It ranks as the most prevalent skin disorder based on disability-adjusted life-years by the World Health Organization. It presents with symptoms like skin irritation, redness, dryness, itchiness, and vesicular blisters and commonly coexists with other atopic symptoms like allergic rhinitis, asthma, and food allergies. The pathophysiology involves a complex interplay of genetic predispositions, immunological dysfunctions, and environmental factors leading to tissue inflammation and disrupted skin barrier integrity. Alopecia areata is characterized by nonscarring hair loss and shares correlations with AD including a higher prevalence of atopic diseases, shared intracellular mechanisms involving the JAK-STAT pathway, and potential treatment overlap such as dupilumab. These correlations could direct new areas of research and increased insight for both diseases. Treatment of AD requires a personalized approach due to its complex, multifactorial nature integrating nonpharmacological interventions like skin hydration and trigger avoidance as well as topical and systemic approaches, if necessary, with topical corticosteroids being the first line for flares; long term corticosteroid use poses risk for adverse effects like skin atrophy. Severe cases may require systemic treatments or phototherapy. Future treatment prospects include targeting the dysbiotic microbiome and identifying biomarkers for tailored therapeutic strategies, emphasizing the importance of personalized medicine in optimizing AD management.

Abstract
A compromised permeability barrier is a hallmark of atopic dermatitis (AD). Localized to the outermost skin layer, the stratum corneum (SC) is critically dependent on terminal differentiation of epidermal keratinocytes, which transform into protein-rich corneocytes surrounded by extracellular lamellae of unique epidermal lipids, conferring permeability barrier function. These structures are disrupted in AD. A leaky barrier is prone to environmental insult, which in AD elicits type 2-dominant inflammation, in turn resulting in a vicious cycle further impairing the SC structure. Therapies directed at enforcing SC structure and anti-inflammatory strategies administered by topical and systemic route as well as UV therapy have differential effects on the permeability barrier. The expanding armamentarium of therapeutic modalities for AD treatment warrants optimization of their effects on permeability barrier function.

Abstract
Background: Crisaborole ointment, 2%, is a nonsteroidal phosphodiesterase 4 inhibitor for the treatment of patients with mild-to-moderate atopic dermatitis (AD). Objective: To assess the efficacy and safety of crisaborole in patients with AD who had received prior treatment with (a) corticosteroids (systemic or topical) or topical calcineurin inhibitors (TCIs) or (b) topical corticosteroids (TCSs) or TCIs or (c) who were treatment-naive (TN). Methods: This post hoc analysis comprised patients aged ≥2 years with mild-to-moderate AD. Patients were assigned (2:1) to receive crisaborole or vehicle twice daily for 28 days. Patient response was assessed with the Investigator's Static Global Assessment (ISGA), Dermatology Life Quality Index (DLQI), Children's Dermatology Life Quality Index (CDLQI), and Dermatitis Family Impact (DFI) tools. Safety was also assessed. Results: A significantly higher percentage of patients treated with crisaborole versus vehicle achieved ISGA success regardless of treatment history. Patients treated with crisaborole had significant reductions in DLQI, CDLQI, and DFI scores versus those who received vehicle regardless of treatment history, with the exception of DLQI and DFI scores in the TN group. Crisaborole was well tolerated in all subgroups. Conclusion: Crisaborole demonstrated a favorable efficacy and safety profile in both treatment-experienced and TN patients.

Abstract
INTRODUCTION Atopic dermatitis (AD) is a chronic disease that occurs mainly in children. Topical corticosteroids are the main treatment for mild to moderate AD, although they can induce side effects. The efficacy and tolerability of xyloglucan and pea protein (XG-PP) was compared with hydrocortisone in pediatric patients with AD as a steroid-sparing solution. METHODS A prospective, multicenter, comparative study enrolled 42 patients (age 0.5-12 years) with mild-to-moderate AD, assigned 1:1 to XG-PP or hydrocortisone ointment. Treatments were applied twice daily for 14 consecutive days and assessed at baseline, day 8, and day 15. Efficacy endpoints were AD Severity Index (ADSI) score, Scoring Atopic Dermatitis (SCORAD) index, and Patient-Oriented Eczema Measure (POEM). Tolerability was assessed by the occurrence of adverse events (AEs). RESULTS Both treatments significantly improved ADSI mean score from baseline to day 15; in the XG-PP arm, ADSI score decreased from 10.55 to 4.15 (p = 0.00001), and in the hydrocortisone arm, from 10.65 to 4.30 (p = 0.0001). In the XG-PP arm, the mean SCORAD score decreased from 65.86 to 30.26 (p = 0.00001) and in the hydrocortisone arm from 68.84 to 31.19 (p = 0.0001) at day 15. An overall decrease from moderate to mild AD for both arms (p = 0.0001) was observed with POEM. For all the three indexes evaluated, no statistical significant differences between the study arms evolution from baseline to day 8 or to day 15 were found. No AEs were reported. CONCLUSION XG-PP provided a comparable efficacy to hydrocortisone ointment in managing AD, thus representing a safe and effective steroid-sparing alternative in pediatric patients with AD. TRIAL REGISTRATION Retrospectively registered on 24 November 2021 in the ISRCTN registry: 11118799.

Abstract
Atopic dermatitis (AD) is a common skin condition and is undertreated in children under 2 years, whom there are no specific guidelines for. We sought to understand barriers to AD treatment and primary care pediatricians' (PCPs) suggested solutions. We conducted semi-structured focus groups (n = 5) with PCPs (n = 17) on how the undertreatment of AD can be addressed. Data were analyzed using an inductive qualitative approach. Participants noted that the perceived undertreatment of AD in children under 2 years could be explained by topical corticosteroid (TCS) use hesitancy, lack of caregiver adherence to PCP recommendations, and under-documentation of AD in the electronic medical record (EMR). Proposed suggestions for improving AD management included caregiver and PCP education on TCS safety; stepwise management guidelines for this age group; and EMR aids to help document and manage AD. Research is warranted to create and disseminate clinician-friendly AD management guidelines for this age group.

Abstract
Atopic dermatitis (AD) is the most common chronic inflammatory skin disease in the general population. Skin barrier dysfunction is the central abnormality leading to AD. The cause of skin barrier dysfunction is complex and rooted in genetic mutations, interactions between the immune pathway activation and epithelial cells, altered host defense mechanisms, as well as environmental influences that cause epithelial cell activation and release of alarmins (such as thymic stromal lymphopoietin) that can activate the type 2 immune pathway, including generation of interleukins 4 and 13, which induces defects in the skin barrier and increased allergic inflammation. These inflammatory pathways are further influenced by environmental factors including the microbiome (especially Staphylococcus aureus), air pollution, stress, and other factors. As such, AD is a syndrome involving multiple phenotypes, all of which have in common skin barrier dysfunction as a key contributing factor. Understanding mechanisms leading to skin barrier dysfunction in AD is pointing to the development of new topical and systemic treatments in AD that helps keep skin borders secure and effectively treat the disease.

Abstract
Atopic dermatitis is a chronic recurring pruritic inflammatory skin disease manifested by increased pro-inflammatory mediators which lead to dry, thickened, cracked, scaly skin. The current treatment options for atopic dermatitis management comprise drawbacks and leave unmet effective clinical needs. So, the approach for repurposing existing drugs for atopic dermatitis management may potentially overcome these unmet needs. Diseases that share the common pathophysiological pathways with atopic dermatitis can serve as a foundation for the repurposing of drugs. Drugs used in the management of cancer, rheumatoid arthritis, and other immune-mediated diseases such as psoriasis are under investigation to know the potential in atopic dermatitis management by utilizing repurposing strategies for a novel therapeutic indication. This review mainly envisages the probable repurposing of drugs for the management of atopic dermatitis disease; the barriers and regulatory aspects involved in the repurposing of existing drugs.

Ryuk JA, Ko BS, Moon NR, Park S. Pinus koraiensis needle or cone extracts alleviate atopic dermatitis symptoms by regulating immunity and suppressing inflammation in HaCaT cells and Nc/Nga mice. J Food Biochem 2022; 46:e14135. [PMID: 35301731 DOI: 10.1111/jfbc.14135] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/09/2021] [Revised: 01/30/2022] [Accepted: 02/24/2022] [Indexed: 11/26/2022]
Abstract
Pinus koraiensis needles (PKN) and cones (PKC) have been shown to protect against inflammation and pathogenic bacteria. We investigated the efficacies and action mechanisms of topical applications of 1,3-butylene glycol (BG) extracts and oral administration of their water extracts on atopic dermatitis (AD) symptoms. After exposing HaCaT cells and Nc/Nga mice dorsal skins to 2,4-dinitrochlorobenzene (DNCB) to induce atopic dermatitis models, they were topically applied BG (AD-control), 30% PKNX, or 30% PKCX to the skin lesions and fed water extracts (0.5%) in high-fat diets for 5 weeks. Normal-control mice had no DNCB exposure. Serum immunoglobulin E (IgE), IL-4, and TNF-α levels and gene expressions of TNF-α, IL-4, IL-6, and IFN-γ in the dorsal skin and HaCaT cells were measured. The AD-control mice elevated TNF-α and IL-6 mRNA levels in HaCaT cells. Both extracts attenuated clinical AD symptoms in AD-induced Nc/Nga mice: PKNX improved hemorrhage, erythema, and lichenification of dorsal skin better than PKCX while both similarly alleviated erythema, edema, excoriation, and itching behavior. PKCX reduced IgE contents and increased filaggrin mRNA expression better than PKNX, but PKNX reduced lipid peroxides and mRNA levels of TNF-α and IL-4 in the dorsal skin. In the histological analysis of the dorsal skin, the administration of both extracts significantly decreased mast cell numbers, immune cell infiltration, gaps between the epidermis and dermis, and abnormal cell and nucleus shapes. In conclusion, both PKCX and PKNX treatment alleviated the DNCB-induced clinical symptoms of AD by alleviating immune-related symptoms and inflammation in partially different pathways. Therefore, PKNX and PKCX may be effective for AD therapy. PRACTICAL APPLICATIONS: Atopic dermatitis (AD) is related to an overly activated immune response, and it has steadily increased last 3 decades. However, no optimal sustainable treatments are available. Pinus koraiensis needles and cones extracts have been used for anti-inflammatory and antimicrobial treatment. The present study demonstrated that their intake and topical administration onto the AD lesion alleviated clinical AD symptoms associated with reduced proinflammatory cytokines, mast cell numbers, and immune cell infiltrates to maintain dermal structure with maintaining filaggrin expression in AD-induced HaCaT cells and Nc/Nga mice. These results suggested that Pinus koraiensis needles and cones extracts can be developed and applied as beneficial alternative therapies for AD.

Abstract
INTRODUCTION Atopic dermatitis is a common dermatologic condition that affects millions of people worldwide, and a standardized approach to treatment was published by the American Academy of Dermatology (AAD) in 2013-14. Since 2014, new FDA-approved treatment options such as dupilumab and crisaborole have changed the landscape of AD management, and future therapies such as JAK inhibitors and anti-interleukin 13 and 31 antibodies appear effective, emphasizing the need for a comprehensive review to give clinicians an updated toolbox to aid in pharmacologic management. AREAS COVERED In this review, the authors explore the updated efficacy and safety data on established therapeutic options for AD including topical corticosteroids, topical calcineurin inhibitors, cyclosporine, azathioprine, methotrexate, and mycophenolate mofetil. In addition, the authors also explore trial data and studies on dupilumab, crisaborole, omalizumab, tofacitinib, ruxolinitib, abrocitinib, baricitinib, upadacitinib, delgocitinib, nemoliuzumab, and tralokinumab. EXPERT OPINION The AAD guidelines must be updated in the future to include several new treatment modalities that have revolutionized the pharmacologic management of patients with AD, including dupilumab and crisaborole. The future of AD treatment is also extremely bright, as JAK inhibitors and Il-13/31 antibodies have shown convincing results in the improvement of AD patients' lives in various trials and studies that have been examined in this paper.

Abstract
Itching is prevalent in children with skin disorders and associated with effects on their mood, quality of life, and social functioning. Surprisingly, there are no data on childhood prevalence of pruritus in the general population. The aim of this article is to explore the epidemiology, clinical manifestation, and treatment for itch (pruritus) in the pediatric population (from infancy to adolescence), and to be helpful to primary care physicians who assess and diagnose pediatric patients with itching. In this study, we searched for specific keywords using PubMed and MEDLINE (Ovid) and, then, refined the retrieved searches for each cause and treatment. As a result of reviewing the literature, atopic dermatitis was shown to be the most common cause of itching, especially during infancy and through preschool. Not only skin disorders but also systemic diseases, drugs, and postburn states can predispose an individual to itching in childhood. There are traditional and newly developed treatment modalities for itching in pediatric patients. However, because the pharmacokinetics and pharmacodynamics of childhood are different from those of adults, the medications for itching have to be applied carefully for these age groups. There are many areas to be elucidated regarding the prevalence and objective assessment of pruritus in pediatric patients. Moreover, the safety profiles of medications in the pediatric population need to be better understood. Further studies to investigate itching in childhood are warranted.

Abstract
OBJECTIVE An umbrella review summarising all safety data from systematic reviews of topical corticosteroids (TCS) in adults and children with atopic eczema. METHODS Embase, MEDLINE, PubMed, Cochrane Database of Systematic Reviews and the Centre of Evidence Based Dermatology map of eczema systematic reviews were searched until 7 November 2018 and Epistemonikos until 2 March 2021. Reviews were included if they assessed the safety of TCS in atopic eczema and searched >1 database using a reproducible search strategy. Review quality was assessed using version 2 of 'A MeaSurement Tool to Assess systematic Reviews' (AMSTAR 2 tool). RESULTS 38 systematic reviews included, 34 low/critically low quality. Treatment and follow-up were usually short (2-4 weeks). KEY FINDINGS TCS versus emollient/vehicle: No meta-analyses identified for skin-thinning. Two 2-week randomised controlled trials (RCTs) found no significant increased risk with very potent TCS (0/196 TCS vs 0/33 vehicle in children and 6/109 TCS vs 2/50 vehicle, age unknown). Biochemical adrenal suppression (cortisol) was 3.8% (95% CI 2.4% to 5.8%) in a meta-analysis of 11 uncontrolled observational studies (any potency TCS, 522 children). Effects reversed when treatment ceased.TCS versus topical calcineurin inhibitors: Meta-analysis showed higher relative risk of skin thinning with TCS (4.86, 95% CI 1.06 to 22.28, n=4128, four RCTs, including one 5-year RCT). Eight cases in 2068 participants, 7 using potent TCS. No evidence of growth suppression.Once daily versus more frequent TCS: No meta-analyses identified. No skin-thinning in one RCT (3 weeks potent TCS, n=94) or biochemical adrenal suppression in two RCTs (up to 2 weeks very potent/moderate TCS, n=129).TCS twice/week to prevent flares ('weekend therapy') versus vehicle: No meta-analyses identified. No evidence of skin thinning in five RCTs. One RCT found biochemical adrenal suppression (2/44 children, potent TCS). CONCLUSIONS W e found no evidence of harm when TCS were used intermittently 'as required' to treat flares or 'weekend therapy' to prevent flares. However, long-term safety data were limited. PROSPERO REGISTRATION NUMBER CRD42018079409.

Abstract
This review forms part of a series of annual evidence updates on atopic eczema (AE), and provides a summary of key findings from systematic reviews (SRs) published or indexed in 2019 related to AE treatment. Several SRs assessed the efficacy of topical corticosteroids (TCS), topical calcineurin inhibitors, topical phosphodiesterase-4 inhibitors and topical Janus kinase/signal transducer and activator of transcription (JAK/STAT) pathway inhibitors. However, there is a lack of good-quality trials comparing topical treatment agents with TCS, which remain the standard of care for patients with AE. Most of the included trials lack meaningful comparisons as they used vehicle as a comparator. There is also lack of harmonization of outcome measures for AE across studies. Large, well-designed RCTs are needed to further determine whether any specific emollients offer superior benefit. There is evidence highlighting limited benefit of oral H1 antihistamines as 'add-on' therapy to topical treatment of eczema. Mycophenolate mofetil may have a role in patients with refractory AE. Among biologic therapies, most of the efficacy data relate to dupilumab. Furthermore, there is growing evidence for the efficacy and safety of systemic JAK/STAT pathway inhibitors, but the existing data are of low quality.

Abstract
Based on new insights into the molecular pathogenesis of atopic dermatitis, a targeted anti-inflammatory therapy-dupilumab-has recently been approved as treatment alongside glucocorticoids and ciclosporin. Due to their pharmacology, neither glucocorticoids nor ciclosporin nor the off label used substances methotrexate, azathioprine and mycophenolic acid derivatives are suitable for long-term therapy. When switching therapy from small molecular substances to dupilumab, various factors should be considered. Both the specific cause of the change (ineffectiveness, adverse effects or contraindications) as well as the pharmacological conditions should be taken into account. Since there have been no specific clinical studies on this subject so far, the authors relied mainly on a literature search to draw up recommendations for practical everyday use.

Abstract
Dysbiosis of the skin microbiota is increasingly implicated as a contributor to the pathogenesis of atopic dermatitis (AD). We previously reported first-in-human safety and clinical activity results from topical application of the commensal skin bacterium Roseomonas mucosa for the treatment of AD in 10 adults and 5 children older than 9 years of age. Here, we examined the potential mechanism of action of R. mucosa treatment and its impact on children with AD less than 7 years of age, the most common age group for children with AD. In 15 children with AD, R. mucosa treatment was associated with amelioration of disease severity, improvement in epithelial barrier function, reduced Staphylococcus aureus burden on the skin, and a reduction in topical steroid requirements without severe adverse events. Our observed response rates to R. mucosa treatment were greater than those seen in historical placebo control groups in prior AD studies. Skin improvements and colonization by R. mucosa persisted for up to 8 months after cessation of treatment. Analyses of cellular scratch assays and the MC903 mouse model of AD suggested that production of sphingolipids by R. mucosa, cholinergic signaling, and flagellin expression may have contributed to therapeutic impact through induction of a TNFR2-mediated epithelial-to-mesenchymal transition. These results suggest that a randomized, placebo-controlled trial of R. mucosa treatment in individuals with AD is warranted and implicate commensals in the maintenance of the skin epithelial barrier.

Abstract
A topical vehicle is a 'carrier system' for an active pharmaceutical (or cosmetic) substance, referred to hereafter as the drug, but a vehicle may also be used on its own as an emollient to ameliorate dry skin. It is well established that the vehicle plays an important role in determining the bioavailability of a given drug at its ultimate target within the skin. Yet in the treatment of atopic eczema/dermatitis (AD), wherein the structure and function of the skin's outer barrier play a pivotal role in the development and course of the condition, the interaction of the vehicle with this barrier carries a particular importance. It is now clear that the often-considered inert excipients of a vehicle bring about changes within the skin at the molecular level that promote barrier restoration and enhance innate immune defenses with therapeutic value to AD patients. Moreover, the vehicle control in randomized controlled trials (RCTs) increasingly displays significant efficacy. In light of this, we consider the implications of vehicle design in relation to AD pathophysiology and the role vehicles play as controls in RCTs of new drug treatments for this condition.

Abstract
Atopic dermatitis (AD) is generally considered a T helper type 2-dominated disease. Pediatric AD is usually less severe than adult AD, but it may present as moderate to severe lesions that are inadequately managed by current modalities including emollients/moisturizers, topical corticosteroids (TCSs), topical calcineurin inhibitors (TCIs), and even systemic immunosuppressants (such as cyclosporine, azathioprine, methotrexate, and mycophenolate mofetil). In addition, systemic immunosuppressants are often not recommended for childhood AD by the current guidelines due to their toxicities. Therefore, there is still an unmet need for a safe and effective long-term therapy for pediatric AD patients whose disease is inadequately controlled or who are intolerant to current treatments. The emerging therapeutics for AD focuses on intervening in the inflammatory pathway by targeting specific cytokines/chemokines or their receptors. Monoclonal antibodies against immunoglobulin E (IgE), interleukin (IL)-4 receptor subunit α, IL-5, IL-13, IL-31 receptor subunit α, IL-33, and thymic stromal lymphopoietin (TSLP) have been evaluated clinically for AD. Encouraging results have been reported for many of the biologics, of which the most exciting is dupilumab. Other emerging systemic therapies include small molecules such as baricitinib, abrocitinib, upadacitinib, and tradipitant. Several novel topical agents are under clinical investigation for the treatment of AD, including topical phosphodiesterase 4 (PDE4) inhibitors, Janus kinase (JAK) inhibitors, aryl hydrocarbon receptor (AhR) modulating agents, and transient receptor potential vanilloid subfamily member 1 (TRPV1) antagonists. Accompanied by thorough characterization of different phenotype and endotype subsets, the application of precision medicine could provide new prospects for the optimal treatment of AD.

J Formos Med Assoc 2020; 120:429-442. [PMID: 32564976 DOI: 10.1016/j.jfma.2020.06.008] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/19/2020] [Revised: 05/23/2020] [Accepted: 06/05/2020] [Indexed: 12/30/2022] Open
Abstract
BACKGROUND/PURPOSE Atopic dermatitis (AD) is a chronic inflammatory disease commonly seen in children and increasingly recognized in adults. With recent advances in the therapeutic development for AD, the Taiwanese Dermatological Association (TDA) established a committee to update the consensus for AD management in Taiwan. This report describes the 2020 updated consensus for the management of AD. METHODS A panel of 11 core members was convened to review and discuss aspects of AD management and draft recommendation during the first two meetings. The 2015 TDA consensus and the 2017 European guideline, along with recent peer-reviewed articles, serve as the foundation for the update. In the third meeting, AD expert dermatologists selected on a national scale were invited to vote on the final statements. A total of 27 dermatologists attended the final meeting. The consensus was achieved when ratings of 7-9 (out of a total score of 9) accounted for ≥ 75% of the total votes. RESULTS Consensus was achieved on the therapeutic options for AD by lines of treatment. A treatment algorithm was presented to illustrate the place of each modality in terms of basic care, acute disease control, and maintenance therapy. Special considerations for the pediatric population, as well as for women during pregnancy and lactation, are discussed. CONCLUSION Topical corticosteroids with long-term emollient-based therapies remain the cornerstone of AD treatment. Systemic treatments are indicated when topical therapies and phototherapy fail to control the disease. The recent approval of dupilumab and emerging targeted therapies are expected to bring significant clinical benefit for patients whose disease is inadequately managed by existing options.

Management of Atopic Dermatitis in Children Younger Than Two Years of Age by Community Pediatricians: A Survey and Chart Review. J Pediatr 2020; 221:138-144.e3. [PMID: 32171558 PMCID: PMC7480084 DOI: 10.1016/j.jpeds.2020.02.015] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/04/2019] [Revised: 02/03/2020] [Accepted: 02/10/2020] [Indexed: 11/22/2022]
Abstract
OBJECTIVES To characterize primary care providers' (PCPs) practice patterns for atopic dermatitis (AD) in children <2 years old and determine the need for AD guidelines for PCPs focused on this age group. STUDY DESIGN This is a mixed-methods study consisting of a survey and a retrospective medical record review of PCP practices in the Chicago metropolitan area. The survey was analyzed using both quantitative and qualitative methods. RESULTS In the survey (n = 52 respondents), PCPs reported management of AD is different in children <2 years compared with older children (88%). They were more likely to refer to a specialist (65%) and less likely to use high-potency topical corticosteroids (64%). In the chart review, PCP visits for children 2-5 years old (n = 50 914) vs those <2 years old (n = 71 913) for AD, older children had medium- and high-potency topical corticosteroids prescribed more frequently than younger children (0.66% vs 0.37%, P < .01 and .15% vs 0.05%, P < .01, respectively). In the subset of children <2 years of age who also were evaluated by a specialist (n = 109), medium- and high-potency topical corticosteroids were prescribed disproportionately at visits to providers in dermatology (57%) vs allergy (30%) vs pediatrics (15%) (P < .01). PCPs suggested that guidelines for this age group should include recommendations for preferred corticosteroids (39%), allergy management (35%), referral criteria (22%), and assessment of disease severity (11%). CONCLUSIONS PCP management of AD in children <2 years is different from older children, with possible underuse of medium/high-potency topical corticosteroids. Clear guidelines for this age group are needed.
