[PMID: 38803495 PMCID: PMC11128609 DOI: 10.3389/fimmu.2024.1388690] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/20/2024] [Accepted: 04/24/2024] [Indexed: 05/29/2024] Open
Abstract
Introduction Psoriasis is a chronic skin disease characterized by unique scaling plaques. However, during the acute phase, psoriatic lesions exhibit eczematous changes, making them difficult to distinguish from atopic dermatitis, which poses challenges for the selection of biological agents. This study aimed to identify potential diagnostic genes in psoriatic lesions and investigate their clinical significance. Methods GSE182740 datasets from the GEO database were analyzed for differential analysis; machine learning algorithms (SVM-RFE and LASSO regression models) are used to screen for diagnostic markers; CIBERSORTx is used to determine the dynamic changes of 22 different immune cell components in normal skin lesions, psoriatic non-lesional skin, and psoriatic lesional skin, as well as the expression of the diagnostic genes in 10 major immune cells, and real-time quantitative polymerase chain reaction (RT-qPCR) and immunohistochemistry are used to validate results. Results We obtained 580 differentially expressed genes (DEGs) in the skin lesion and non-lesion of psoriasis patients, 813 DEGs in mixed patients between non-lesions and lesions, and 96 DEGs in the skin lesion and non-lesion of atopic dermatitis, respectively. Then 144 specific DEGs in psoriasis via a Veen diagram were identified. Ultimately, UGGT1, CCNE1, MMP9 and ARHGEF28 are identified for potential diagnostic genes from these 144 specific DEGs. The value of the selected diagnostic genes was verified by receiver operating characteristic (ROC) curves with expanded samples. The the area under the ROC curve (AUC) exceeded 0.7 for the four diagnosis genes. RT-qPCR results showed that compared to normal human epidermis, the expression of UGGT1, CCNE1, and MMP9 was significantly increased in patients with psoriasis, while ARHGEF28 expression was significantly decreased. Notably, the results of CIBERSORTx showed that CCNE1 was highly expressed in CD4+ T cells and neutrophils, ARHGEF28 was also expressed in mast cells. Additionally, CCNE1 was strongly correlated with IL-17/CXCL8/9/10 and CCL20. Immunohistochemical results showed increased nuclear expression of CCNE1 in psoriatic epidermal cells relative to normal. Conclusion Based on the performance of the four genes in ROC curves and their expression in immune cells from patients with psoriasis, we suggest that CCNE1 possess higher diagnostic value.

Acupoint Autohemotherapy Attenuates DNCB-Induced Atopic Dermatitis and Activates Regulatory T Cells in BALB/c Mice. J Inflamm Res 2024; 17:2839-2850. [PMID: 38751687 PMCID: PMC11094283 DOI: 10.2147/jir.s454325] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/17/2024] [Accepted: 04/16/2024] [Indexed: 05/18/2024] Open
Abstract
Purpose Acupoint autohemotherapy (A-AHT) has been proposed as an alternative and complementary treatment for atopic dermatitis (AD), yet the exact role of its blood component in terms of therapeutic efficacy and mechanism of action is still largely unknown. Methods This study aimed to evaluate the therapeutic efficacies and action mechanisms of intramuscular injections of autologous whole blood (AWB) and mouse immunoglobulin G (IgG) (autologous or heterologous) at acupoints on 2,4-dinitrochlorobenzene (DNCB)-induced AD mouse models. Serum levels of total immunoglobulin E (IgE), IgG, interleukin-10 (IL-10), and interferon-gamma (IFN-γ) were measured, as well as mRNA expression levels of Forkhead box P3 (FoxP3), IL-10 and IFN-γ in dorsal skin lesions, and IL-10+, IFN-γ+ and FoxP3+CD4+T cells in murine spleen. Results It showed that repeated acupoint injection of AWB, autologous total IgG (purified from autologous blood in AD mice) or heterologous total IgG (purified from healthy blood in normal mice) effectively reduced the severity of AD symptoms and decreased epidermal and dermal thickness as well as mast cells in skin lesions. Additionally, AWB acupoint injection was found to upregulate FoxP3+, IL-10+ and IFN-γ+ CD4+T cells in murine spleen, suppressing the production of IgE antibodies and increasing that of IgG antibodies in the serum. Furthermore, both AWB and autologous total IgG administrations significantly elevated FoxP3 expression, mRNA levels of IL-10 and IFN-γ in dorsal skin lesions. However, acupoint injection of heterologous total IgG had no effect on regulatory T (Treg) and Th1 cells modulation. Conclusion These findings suggest that the therapeutic effects of A-AHT on AD are mediated by IgG-induced activation of Treg cells.

Abstract
Eczema herpeticum (EH) is a cutaneous manifestation of disseminated herpes simplex virus, commonly observed in patients with active eczema. The condition often presents with systemic symptoms, including fever and fatigue, alongside vesiculopustular skin lesions. This case report describes a 19-year-old male with active eczema who was misdiagnosed with facial cellulitis in the emergency and inpatient setting in a community tertiary hospital. With worsening rash and development of ocular symptoms, the diagnosis was reconsidered to be more consistent with EH with herpetic keratitis, which improved with antiviral treatment. This report shows the significance of maintaining a high index of suspicion for EH in patients with eczema and the potential consequences of misdiagnosis and delay in treatment. It aims to enhance clinician awareness of EH and promote a broader differential for unusual presentations of common dermatological and ophthalmologic conditions, especially when caring for patients with limited access to specialist evaluation.

Abstract
Common characteristics in the pathogenesis of psoriasis (PS) and atopic dermatitis (AD) have been presumed, but only a few studies have clearly supported this. The current aim was to find possible similarities and differences in protein expression patterns between these two major chronic inflammatory skin diseases. High-throughput tandem mass spectrometry proteomic analysis was performed using full thickness skin samples from adult PS patients, AD patients and healthy subjects. We detected a combined total of 3045 proteins in the three study groups. According to principal component analysis, there was significant overlap between the proteomic profiles of PS and AD, and both clearly differed from that of healthy skin. The following validation of selected proteins with western blot analysis showed similar tendencies in expression levels and produced statistically significant results. The expression of periostin (POSTN) was consistently high in AD and very low or undetectable in PS (5% FDR corrected p < 0.001), suggesting POSTN as a potential biomarker to distinguish these diseases. Immunohistochemistry further confirmed higher POSTN expression in AD compared to PS skin. Overall, our findings support the concept that these two chronic skin diseases might share considerably more common mechanisms in pathogenesis than has been suspected thus far.

Abstract
BACKGROUND Response to abrocitinib treatment for moderate-to-severe atopic dermatitis (AD) has not been evaluated across racial and ethnic subpopulations. OBJECTIVE To assess the efficacy and safety of abrocitinib on the basis of patient race, ethnicity, and Fitzpatrick skin type (FST). METHODS Data were pooled post hoc from patients treated with abrocitinib 200 mg, 100 mg, or placebo in 3 monotherapy trials (NCT02780167, NCT03349060, and NCT03575871). Race and ethnicity were self-reported; FST was determined by study investigators. Evaluations through Week 12 include the following: (1) Investigator's Global Assessment of clear or almost-clear skin; (2) greater than or equal to 75% improvement in Eczema Area and Severity Index or SCORing AD; (3) a greater-than-or-equal-to 4-point improvement in Peak Pruritus Numerical Rating Scale score; (4) least squares mean changes in Dermatology Life Quality Index and Patient-Oriented Eczema Measure scores; and (5) treatment-emergent adverse events. RESULTS The sample comprised 628 White, 204 Asian, and 83 Black patients; 37 were Hispanic or Latino; 624 had FST I to III and 320 had FST IV to VI. Treatment with either abrocitinib dose was associated with greater proportions of patients achieving Investigator's Global Assessment of clear or almost-clear skin, ≥ 75% improvement in Eczema Area and Severity Index, ≥ 75% improvement in SCORing AD, and a ≥ 4-point improvement in Peak Pruritus Numerical Rating Scale, or greater score changes from baseline in Dermatology Life Quality Index and Patient-Oriented Eczema Measure vs placebo regardless of race, ethnicity, or FST. Dose-response was most prominent in White patients. In Black patients, the effects of the 2 doses were similar. Treatment-emergent adverse events were more common in White and Black than in Asian patients. CONCLUSION Abrocitinib was more efficacious than placebo across the racial and ethnic groups and ranges of phototypes analyzed. Studies with increased representation of populations of color are warranted to elucidate potential variations in response across diverse populations. TRIAL REGISTRATION Clinicaltrials.gov Identifier: NCT02780167 (phase 2b), NCT03349060 (phase 3 MONO-1), and NCT03575871 (phase 3 MONO-2).

Dupilumab Treatment Leads to Rapid and Consistent Improvement of Atopic Dermatitis in All Anatomical Regions in Patients Aged 6 Months to 5 Years. Dermatol Ther (Heidelb) 2023; 13:1987-2000. [PMID: 37480432 PMCID: PMC10442292 DOI: 10.1007/s13555-023-00960-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/02/2023] [Accepted: 06/05/2023] [Indexed: 07/24/2023] Open
Abstract
INTRODUCTION Atopic dermatitis (AD) is heterogeneous in distribution pattern and clinical features. This analysis assessed the effect of dupilumab on the extent and severity of AD across various signs (erythema, edema/papulation, excoriation, lichenification) in different anatomical regions (head and neck, trunk, upper extremities, lower extremities) in patients aged 6 months to 5 years. METHODS In LIBERTY AD PRESCHOOL, a double-blind, placebo-controlled, phase III clinical trial, children aged 6 months to 5 years with moderate-to-severe AD were randomized 1:1 to subcutaneous dupilumab or placebo with concomitant low-potency topical corticosteroids (TCS) every 4 weeks for 16 weeks. Changes in AD signs across anatomical regions were assessed using unweighted Eczema Area and Severity Index (EASI) body region scores. RESULTS Overall, 162 patients were randomized to dupilumab (n = 83) or placebo (n = 79). A significant improvement in least squares mean EASI area score was seen by week 2 in all four anatomical regions (P < 0.0001 for dupilumab vs. placebo) and sustained throughout treatment. Least squares mean EASI sign scores in erythema, excoriations, and infiltration/papulation showed significant improvement by week 2 in all regions (P < 0.001), while lichenification showed significant improvement in all regions by week 4 (P < 0.001). CONCLUSION Dupilumab use with concomitant low-potency TCS treatment resulted in rapid and consistent improvement in AD signs in all anatomical regions, in patients aged 6 months to 5 years with moderate-to-severe AD.

Abstract
Atopic dermatitis (AD) is a chronic inflammatory skin disease with a high prevalence in the developed countries. It is associated with atopic and non-atopic diseases, and its close correlation with atopic comorbidities has been genetically demonstrated. One of the main roles of genetic studies is to comprehend the defects of the cutaneous barrier due to filaggrin deficit and epidermal spongiosis. Recently, epigenetic studies started to analyze the influence of the environmental factors on gene expression. The epigenome is considered to be a superior second code that controls the genome, which includes alterations of the chromatin. The epigenetic changes do not alter the genetic code, however, changes in the chromatin structure could activate or inhibit the transcription process of certain genes and consequently, the translation process of the new mRNA into a polypeptide chain. In-depth analysis of the transcriptomic, metabolomic and proteomic studies allow to unravel detailed mechanisms that cause AD. The extracellular space and lipid metabolism are associated with AD that is independent of the filaggrin expression. On the other hand, around 45 proteins are considered as the principal components in the atopic skin. Moreover, genetic studies based on the disrupted cutaneous barrier can lead to the development of new treatments targeting the cutaneous barrier or cutaneous inflammation. Unfortunately, at present, there are no target therapies that focus on the epigenetic process of AD. However, in the future, miR-143 could be an important objective for new therapies, as it targets the miR-335:SOX axis, thereby restoring the miR-335 expression, and repairing the cutaneous barrier defects.

Abstract
Atopic dermatitis is a chronic inflammatory skin disease associated with multiple allergies in the atopic march. It has a complex pathogenesis, related to genetic, immune, and environmental factors. Its incidence and prevalence are increasing in the last decades, especially in developed countries. It affects the quality of life due to the recurrent lesions and the associated pruritus. Thus, it is very important to use non-invasive techniques to manage and follow-up the patients with such a heterogenous disease that can have a high impact on some of them. The reflectance confocal microscope is a modern device for in vivo visualization of the epidermis and the upper dermis which could replace in some cases the cutaneous biopsy. We report a case of a patient with atopic dermatitis investigated with the confocal reflectance microscope at the beginning of the topical treatment with calcineurin inhibitors and three weeks after, with favorable evolution. Reflectance confocal microscopy allows the assessment of the dynamic changes in the skin during treatment. Moreover, it can be useful for highlighting discrete changes even in the subclinical stages of the inflammatory process. Future developments, which will lead to the definition and validation of reflectance confocal microscopy criteria for the diagnosis and staging of atopic dermatitis, could help to improve the treatment and prevention strategies of the disease.

Abstract
Atopic dermatitis (AD) is a chronic inflammatory, itching skin with a significant psychosocial impact on patients and relatives. In adults and adolescents besides flexural eczema, head and neck eczema, and hand eczema, which are the most frequent clinical phenotypes (84.9% and 84.2%, respectively), there are also other possible presentation such as, portrait-like dermatitis (20.1%), diffuse eczema (6.5%), eczema nummulare-like (5.8%), prurigo nodularis-like (2.1%) and erythrodermia (0.7%). Diagnosis can be easy due to the typically distributed eczematous lesions, albeit with age-related differences, However, it is also extremely heterogeneous in severity, course, and sometimes particular clinical features. Currently, there are no better diagnostic criteria than an experienced dermatologist for the diagnosis of AD. Misdiagnosis and delayed treatment will have an impact not only on the child's physical health, but also and especially on the child's psychological health. The aim of our review was to group the main differential diagnoses in pediatric age where the diagnosis can often hide many pitfalls.

AD pathogenesis is complex and several factors are implicated. Pruritus plays a pivotal role in disease's burden, significantly worsening atopic patient quality of life by limiting productivity and daily activities. AD diagnosis relies still on the experience of the healthcare professional and there are several unmet needs as for the diagnostic criteria, the management and the recognition of the burden of the disease. In this paper we present an indeep focus on the main clinical features of AD and the major unmet needs that should be addressed in the next research.

Effects of Oral Administration of Lactiplantibacillus Plantarum APsulloc 331261 (GTB1TM) Isolated from Green Tea on Atopic Dermatitis (AD)-like Skin Lesion Mouse Models. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2022; 2022:4520433. [PMID: 36110182 PMCID: PMC9470305 DOI: 10.1155/2022/4520433] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/18/2022] [Revised: 07/25/2022] [Accepted: 08/04/2022] [Indexed: 11/25/2022]
Abstract
Background Probiotics are known to improve atopic dermatitis (AD) by inhibiting T helper 2 (Th2)-related reactions, restoring the Th2/T helper1 (Th1) cytokine ratio. The most popular probiotic is Lactiplantibacillus plantarum (L. plantarum), which is widely used in the food and pharmaceutical industries. L. plantarum APsulloc 331261 (GTB1) used in this study was isolated from green tea. Materials and Methods The effectiveness of oral GTB1 administration in improving AD was evaluated by visual evaluation, comparison of the lymph node sizes and spleen weights, histological evaluation, RT-qPCR, ELISA, and IHC analysis in the mouse model. Results GTB1 improved AD symptoms, reduced epidermal thickness and mast cell numbers, decreased lymph node size and the spleen weight, increased filaggrin and loricrin protein levels, downregulated Th2 expression, and upregulated Th1 expression in a colony-forming unit-dependent manner. Conclusion Oral administration of GTB1 isolated from green tea (Camellia sinensis) improved the AD symptoms, reduced hypersensitivity reaction, and increased the skin barrier function. Finally, it is involved in AD improvement by restoring the Th2/Th1 cytokine balance.

Abstract
PURPOSE OF REVIEW To report current knowledge on the different clinical phenotypes of adult atopic dermatitis. Possible therapeutic intervention in relation to phenotype is also evaluated. RECENT FINDINGS Atopic dermatitis is a chronic inflammatory disease affecting up to 10% of adults. It can manifest with different clinical phenotypes, causing diagnostic difficulties. Long-term is often required and systemic drugs are needed for moderate-to-severe forms. However, few drugs are registered for atopic dermatitis in many countries. Furthermore, limited data exist regarding the treatment in relation to individual clinical phenotypes. SUMMARY Currently, the most relevant data are those for cyclosporine, alitretinoin, and dupilumab. Cyclosporine and dupilumab showed to be effective in the treatment of atopic dermatitis, although in trials and real-life experiences the different phenotypes treated are usually not reported. However, cyclosporine appears to be effective in prurigo nodularis. Alitretinoin is reported to be particularly efficacious for atopic dermatitis of the hands, while it is ineffective for other locations of the disease. Dupilumab demonstrated its efficacy in prurigo nodularis and nummular eczema phenotypes of atopic dermatitis; moreover, especially in elderly patients, its effectiveness seems to be faster if the folds of the limbs are involved.

Abstract
BACKGROUND Psoriasis is a chronic, immune-mediated inflammatory disease with prominent cutaneous features, although the limited number of medications approved for pediatric psoriasis makes treating this population difficult. This review provides an overview of the challenges associated with diagnosing and treating pediatric psoriasis as well as the approved and off-label treatments for children and infants with psoriasis. METHODS Articles relevant to pediatric psoriasis were identified using series of PubMed searches. Topics relevant to pediatric psoriasis were explored, including disease characteristics, epidemiology, treatment efficacy and safety, and access to care. Publications previously known to the authors were also included. RESULTS Clinical features of psoriasis can be challenging to identify clinically, and patients face challenges gaining access to treatment. Most medications that have been approved for adult psoriasis lack data and labelling to support safe and effective use in pediatric patients, and therefore access is limited. A growing number of clinical trials using biologic agents for pediatric psoriasis aim to broaden available treatment options but may also raise unique concerns associated with the use of these medications in children. CONCLUSION Pediatric psoriasis is underrecognized and often undertreated. Clinicians must balance relative risks and potential benefits when developing a treatment strategy for these patients.

Abstract
OBJECTIVE Provide a review of atopic dermatitis management, focusing on optimizing topical therapy, creating a stepwise approach for treatment plans, and providing guidance on when to start systemic therapy. DATA SOURCES PubMed search of articles in the English language regarding atopic dermatitis in all ages. STUDY SELECTION Articles on the subject matter were selected and reviewed. RESULTS Topical corticosteroids are the first-line treatment for managing atopic dermatitis. Topical nonsteroidal agents, calcineurin inhibitors, crisaborole, and recently, ruxolitinib, which cause no cutaneous atrophy, are options for reducing the use of topical corticosteroids, including on sensitive sites. Emerging topical agents are in clinical trials. Proactive management, with continued application 2 to 3 times weekly of a midpotency topical corticosteroid or tacrolimus, may maintain control for clear (or almost clear) localized sites of dermatitis that rapidly recur when topical anti-inflammatory medication is stopped. If topical therapy alone cannot control disease and quality of life is impacted, reevaluation to confirm the diagnosis, manage comorbid conditions, address compliance and patient-specific concerns, and optimize topical therapy must be undertaken before deciding to advance to systemic medication. Dupilumab, an interleukin-4 receptor inhibitor, has become first-line systemic therapy given its efficacy and safety, allowing long-term treatment without laboratory monitoring. Other biologics and Janus kinase inhibitors are emerging as alternatives that could eliminate the need for immunosuppressants with their higher risks. CONCLUSION Several options are now available for topical treatment. A stepwise approach is needed to consider alternative therapies and diagnoses before advancing to systemic treatment, but the safety of newer immunomodulators will lower the threshold for more aggressive intervention.

Abstract
Introduction As research continues, new drugs will no doubt be added to the current pool of treatments for moderate-to-severe atopic dermatitis (AD). This raises the need for studies to determine prescriber preferences for different pharmacological options and the factors that influence their choice of treatment. Here we aim to explore physician preferences in the systemic treatment of moderate-to-severe AD, identify the sociodemographic characteristics that can influence physician preferences, and evaluate their satisfaction with current AD therapies. Methods A discrete-choice experiment (DCE) survey was administered to physicians treating patients with AD in Spain. Results were analyzed using a conditional logit model to estimate the relative importance of each attribute and the maximum risk accepted to achieve therapeutic benefit. Results A total of 28 respondents completed the DCE survey (67.9% female, mean age 45.9 years). Participants identified objective clinical efficacy and risk of severe adverse events (AEs) as the most important attributes, followed by improvement in sleep and pruritus and faster onset of action from the start of the treatment. Respondents gave less importance to mode of administration and therapeutic benefit in other atopic conditions. Respondents were willing to accept an increased risk of severe AEs and mild-to-moderate AEs leading to treatment discontinuation due to intolerance in order to obtain improvements in efficacy, sleep, and pruritus, and long-term clinical benefit. Conclusion Our findings can help prescribers choose the most appropriate systemic AD therapy.

Abstract
Atopic dermatitis (AD) is a chronic, inflammatory skin condition commonly
affecting infants with notable sparing of the diaper region. Though
sources anecdotally attribute this sparing to the physical barrier
formed by the diaper and the subsequent retention of moisture, urine,
sweat and feces, no studies have formally investigated the factors
contributing to this sparing phenomenon. We performed a scoping
literature review to investigate the factors involved in sparing of AD
in the diaper region, namely humidity, scratching, urine, sweat,
feces, and microbiome composition. A total of 130 papers met the
inclusion criteria, and extracted data were analyzed in an iterative
manner. Increased local humidity facilitates protective changes at the
cellular level and offsets transepidermal water loss. Exposure to urea
from both sweat and urine may contribute to improved moisturization of
the skin through its natural humectant properties and ability to
modulate gene expression. Introduction of flora in feces contributes
to the generation of protective immune responses and outcompetes
growth of pathogens such as Staphylococcus aureus.
Finally, diapers physically prevent scratching, which directly
interrupts the itch-scratch cycle classically implicated in AD. Our
study reviews factors that may contribute to the sparing of AD in the
diaper region in infants. A limitation to our findings is that the
studies reviewed here explore the impacts of these factors on AD
broadly, and not explicitly in the diaper region. Additional studies
investigating this may further our understanding of AD pathogenesis
and contribute to the development of effective therapeutics.

Abstract
OBJECTIVES To assess the associations of sensitisation to common allergens with atopic dermatitis, allergic rhinitis and allergic asthma in adults. DESIGN Case-control study. SETTING Data were collected from the First Affiliated Hospital of Harbin Medical University in Harbin, China. PARTICIPANTS Cases were 5111 patients with physician-diagnosed atopic dermatitis (n=2631), allergic asthma (n=1320) and allergic rhinitis (n=1160) recruited from the department of allergy from March 2009 to December 2017. Controls were 2576 healthy adults who underwent physical examination at the same hospital during the same period. MAIN OUTCOME MEASURES Specific IgE levels to 16 common food, indoor and outdoor allergens were assessed in all participants. Adjusted ORs and 95% CIs for the association between allergen sensitisation and allergic diseases were estimated using multivariate logistic regression. RESULTS The prevalence of allergen sensitisation was higher in patients with atopic dermatitis (indoor=17.14%, outdoor=12.85%, food=21.44%), allergic rhinitis (indoor=23.18%, outdoor=26.81%, food=8.94%) and allergic asthma (indoor=24.65%, outdoor=16.46%, food=14.31%) compared with controls (indoor=11.03%, outdoor=6.84%, food=5.83%). After adjustment for potential confounding variables, there was a dose-response relevance between the levels of allergen-specific IgE and allergic diseases (p trend <0.0001). The number of allergens to which a patient was sensitised increased the risk of allergic diseases (atopic dermatitis: highest adjusted OR=4.28, 95% CI 2.57 to 7.11; allergic rhinitis: highest adjusted OR=13.00, 95% CI 3.76 to 45.00; allergic asthma: OR=2.37, 95% CI 1.67 to 3.37). CONCLUSION There was a dose-response relevance between levels of allergen-specific IgE and allergic diseases' prevalence, and multiple sensitisations increased the risk of allergic diseases. This study provides evidence for the prophylaxis of allergic diseases.

Abstract
Atopic dermatitis (AD) is frequently misdiagnosed and undertreated, resulting in increased morbidity. In 2019, the Atopic Dermatitis Quality of Care Initiative was launched globally to investigate barriers to AD care and note good practice interventions to improve care. The initiative included a literature review to define the challenges in AD and a survey of 32 AD centers to define good practice interventions. One topic studied was best practices for clinical assessment and diagnosis. The literature review revealed the primary gaps included difficulty differentiating AD from other skin disorders, diagnosing atypical AD, staging AD severity in individual patients, and delays in assessment and treatment due to referral time lag. The best clinical practices used by leading AD centers included the use of validated diagnostic criteria, established AD scoring tools including patient-reported outcome measures and electronic health records (EHR), the formation of multidisciplinary teams (MDTs), and improved communication between health care providers (HCPs) and patients. Most centers worked with patient advocacy groups and implemented educational programs for HCPs. AD centers are overcoming issues in AD care. Educating health care providers and the public, using screening surveys, using established guidelines, and communicating with MCTs and patients through EHRs are the most frequently used strategies.

Abstract
Background Atopic dermatitis (AD) is a common health problem found in children. Understanding of the determinants of AD-related factors includes gender, family history, childbirth history, and exclusive breastfeeding. Objective Analyzing gender, family history, childbirth history, and exclusive breastfeeding on recurrence of AD symptoms in children. Methods This study employed a cross-sectional design with a purposive sampling method. The procedure for collecting data in this study included data on participant recurrence, gender, family history of atopy disease, childbirth history, and exclusive breastfeeding. The analysis used Chi-square and eta correlation test with p < 0.05. Results The results showed that 56.0% of male participants experienced recurrent atopic dermatitis symptoms and 56.7% of female participants did not experience recurrence (OR = 1.664; p = 0.349). It was reported that 61.3% of participants did not experience recurrent atopic symptoms with a family history of 1 atopic person and 71.4% of participants experienced recurrence with 2 atopic families (F = 2114; p = 0.349). Most participants who were delivered through cesarean delivery did not experience recurrent atopic dermatitis symptoms as much as 56.0%, while participants who had a history of spontaneous delivery mostly experienced recurrent atopic dermatitis symptoms as much as 52.9% (OR = 1.500; p = 0.467). There was a significant association between participants who received exclusive breastfeeding and recurrent atopic dermatitis symptoms (OR = 4.444; p = 0.032). Conclusion Recurrent of AD is influenced by exclusive breastfeeding and not influenced by gender, family history of atopy disease, and history of childbirth. No significant association of gender, family history, and childbirth on recurrence of atopic dermatitis symptoms. There is a significant association between exclusive breastfeeding and recurrent atopic dermatitis. Participants who experience atopic dermatitis as much as 57.1% consume exclusive breastfeeding.

Abstract
The incidence of atopic dermatitis (AD), a disease characterized by an abnormal immune balance and skin barrier function, has increased rapidly in developed countries. This study investigated the anti-atopic effect of Lithospermum erythrorhizon (LE) using NC/Nga mice induced by 2,4-dinitrochlorobenzene. LE reduced AD clinical symptoms, including inflammatory cell infiltration, epidermal thickness, ear thickness, and scratching behavior, in the mice. Additionally, LE reduced serum IgE and histamine levels, and restored the T helper (Th) 1/Th2 immune balance through regulation of the IgG1/IgG2a ratio. LE also reduced the levels of AD-related cytokines and chemokines, including interleukin (IL)-1β, IL-4, IL-6, tumor necrosis factor-α (TNF-α), thymic stromal lymphopoietin, thymus and activation-regulated chemokine, macrophage-derived chemokine, regulated on activation, normal T cell expressed and secreted, and monocyte chemoattractant protein-1 in the serum. Moreover, LE modulated AD-related cytokines and chemokines expressed and secreted by Th1, Th2, Th17, and Th22 cells in the dorsal skin and splenocytes. Furthermore, LE restored skin barrier function by increasing pro-filaggrin gene expression and levels of skin barrier-related proteins filaggrin, involucrin, loricrin, occludin, and zonula occludens-1. These results suggest that LE is a potential therapeutic agent that can alleviate AD by modulating Th1/Th2 immune balance and restoring skin barrier function.

Abstract
Acyclovir (ACV) and penciclovir and their prodrugs are recommended for therapy or prophylaxis of Herpes simplex virus 1 (HSV-1) infections. Their administration, however, can lead to the emergence of resistant strains with altered viral thymidine kinase (TK) function, especially in immunocompromised patients. Furthermore, amino acid (aa) changes of the viral deoxyribonucleic acid polymerase (POL) may contribute to resistance to the aforementioned nucleoside analogues. Given this, treatment with foscarnet (FOS) or cidofovir (CDV) may represent an important alternative. Both drugs directly affect POL activity. Several aa changes of POL, such as L49I, E70K, L359I, E421V, P829S, T1121M, and M1226I, have been observed in ACV-resistant clinical strains which also carried relevant aa changes in their TK. Their contribution to ACV, FOS, and CDV resistance is not fully understood. In this study, these seven aa changes with unknown significance for ACV, FOS and CDV resistance were introduced separately into the POL of a recombinant HSV-1 strain rHSV-1(17+)Lox, equipped with or without information for expression of green fluorescent protein (GFP). The GFP-expressing variants were tested for susceptibility to ACV, FOS and CDV. An rHSV-1(17+)Lox GFP strain with the S724N change conferring resistance to ACV and FOS was generated and included as a control. Only the S724N change was confirmed to induce ACV and FOS resistance, whereas the other changes did not contribute to resistance. The underlying nucleotide substitutions of the POL gene should be therefore considered as natural polymorphism. These data will improve sequence-based prediction of antiviral susceptibility.

Guttman E, Nosbaum A, Simpson E, Weidinger S. Pioneering Global Best Practices in Atopic Dermatitis: Results from the Atopic Dermatitis Quality of Care Initiative. Clin Exp Dermatol 2021; 47:303-311. [PMID: 34382243 DOI: 10.1111/ced.14880] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/12/2021] [Revised: 07/12/2021] [Accepted: 08/09/2021] [Indexed: 11/28/2022]
Abstract
BACKGROUND Atopic dermatitis (AD) is a chronic inflammatory skin disease characterized by unrelenting pruritus and recurrent eczematous lesions. It affects up to 15% of children and adolescents and up to 5% of adults and confers a high and multifactorial burden to patients, families, and society. With increasing awareness of this substantial burden, AD has become a priority for healthcare systems. OBJECTIVE The Atopic Dermatitis Quality of Care (ADQoC) Initiative set out to describe good practices for addressing the challenges that impede the management of AD. METHODS The Initiative carried out a literature review and surveyed 32 expert care centres, catalogued findings, and analysed and elucidated global challenges to AD care along with good practice implementations that can address them. RESULTS The four challenges to quality care for AD are: misconceptions about AD; delayed referral and access to AD specialists; poor patient access to AD treatments and poor adherence to medications; and managing the complexity of atopic dermatitis and its comorbidities. The Initiative highlighted five of ten good practice implementations as high priority for any AD care centre to focus: clinical assessment and diagnosis; a structured multidisciplinary care team; monitoring and evaluating care quality; patient education and communication; and collaboration and exchange with patient groups. CONCLUSIONS These implementations can provide benefits for patients, healthcare providers, and the healthcare system. They directly contribute to the efficacy of treatment; improved healthcare provider efficiency; improved education; and improved costs to healthcare systems. The Initiative was launched on https://atopicdermatitiscare.kpmg.co.uk/ to provide an easy-to-use educational platform.

Abstract
BACKGROUND The burden of coronavirus disease 2019 (COVID-19) among patients with atopic dermatitis (AD) is poorly understood. OBJECTIVES The aims of the study were to characterize a large cohort of COVID-19-positive adult patients with AD and to identify predictors of COVID-19-associated hospitalization and mortality. METHODS A population-based nested case-control study was performed. Multivariable logistic regression was used to evaluate odds ratios and 95% confidence intervals of predictors for COVID-19-associated hospitalization and mortality. RESULTS Of 78,073 adult patients with AD, 3618 (4.6%) tested positive for COVID-19. Subclinical COVID-19 infection occurred in 3368 (93.1%) of COVID-19-positive patients, whereas 123 (3.4%), 46 (1.3%), 55 (1.5%), and 26 (0.7%) patients developed a mild, moderate, severe, and critical disease, respectively. Altogether, 250 patients (6.0%) were hospitalized, and 40 patients (1.1%) died because of COVID-19 complications. Coronavirus disease 2019-associated hospitalization was independently associated with the intake of extended courses of systemic corticosteroids (adjusted odds ratio, 1.96; 95% confidence interval, 1.23-3.14; P = 0.005). None of AD-related variables independently predicted COVID-19-associated mortality. The presence of comorbid metabolic syndrome, chronic obstructive pulmonary disease, chronic renal failure, and depression projected both COVID-19-associated hospitalization and mortality. CONCLUSIONS Prolonged systemic corticosteroids during the pandemic are associated with increased odds of COVID-19-associated hospitalization and should be avoided in patients with AD.

Abstract
Even though allergic disease is identified in the first year of life, it is often in a less forward fashion, with elements of a wait and see approach. If the infant does not have an anaphylactic food reaction, other less dramatic allergic phenomenon is often under-emphasized, waiting for additional concerns. We approached this with a conception to first conduct birthday surveys, attempting to link intrauterine and peri-birth circumstances to affect better allergy recognition in young infants.

Abstract
Atopic dermatitis is a heterogeneous disease and resists classification. In this review, we discuss atopic dermatitis nomenclature and identify morphologic phenotypes, which will facilitate correct diagnoses and development of treatment strategies. We support using the term 'atopic dermatitis' rather than eczema, because it describes the allergic background and inflammation ('itis') as drivers of the disease. Atopic dermatitis has many morphologic manifestations that vary by topographic area affected, age, or race and require consideration in differential diagnosis. Different phenotypes based on morphology and topographic location, ethnicity, and age are discussed. A better-defined phenotype identification for atopic dermatitis will facilitate earlier and correct diagnosis of this complex condition and inform selection of the most appropriate treatment choice in an era in which targeted therapies may generate more individualized patient care.

Knowledge and Practices of Community Pharmacists in Topical Dermatological Treatments. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2021; 18:ijerph18062928.

Abstract
The connection between pharmacists’ knowledge and practice on the provided information to patients about dermatoses and their treatment is insufficiently characterized. Furthermore, pharmacists’ contributions in counselling and in promoting adherence to topical treatment is not fully understood. This study has three main objectives. It aims to identify the knowledge and practices of pharmacists about dermatoses and their treatment, and to compare the perspective of pharmacists with that of patients regarding treatment information, with the future goal of establishing guidelines on the communication of dosage regimen instructions to dermatological patients and promotion of adherence to treatment, filling a gap. A cross-sectional, exploratory, and descriptive study was carried out. Based on experts’ prior knowledge and extensive collected literature information, two questionnaire protocols, one for pharmacists and another one for patients, were designed. Exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were carried out in relation to the pharmacists’ questionnaire for instrument validation. The results indicate that knowledge of pharmacists regarding dermatoses and their treatment is considered acceptable. Most of the pharmacists were reported to provide information to patients. Oppositely, patients reported not to have receive it. This is an important issue because pharmacists play a primary role in the management of several diseases. As non-adherence can be triggered by poor understanding of the dosing instructions, pharmacists’ communication practices play an important role in improving this hinderance. Results from this study identified pharmacist–patient communication gaps, so the development of guidelines to improve the transmission of clear dosage regimen instructions and knowledge about patient’s disease are of paramount importance. Training programs for continuous education of pharmacist should be implemented to solve the identified communication problems found in this study.

Abstract
BACKGROUND Diagnosing atopic dermatitis (AD) in infants is challenging. OBJECTIVES To determine the incidence and persistence of eczema and AD in infants using the UK Working Party (UKWP) and Hanifin and Rajka (H&R) criteria. METHODS A cohort of 1834 infants was examined clinically at 3, 6 and 12 months of age. AD was diagnosed by UKWP (3, 6 and 12 months) and H&R (12 months) criteria. Logistic regression models were used to assess the relationship between AD and eczema. RESULTS Eczema was observed in 628 (34·2%) infants (n = 240, n = 359 and n = 329 at 3, 6 and 12 months, respectively), with AD diagnosed in 212 (33·7%) infants with any eczema and in 64/78 (82%) infants with eczema at all three visits. The odds of AD were lower with first presentation of eczema at 6 [odds ratio (OR) 0·33, 95% confidence interval (CI) 0·22-0·48] or 12 months (OR 0·49, 95% CI 0·32-0·74) than at 3 months, and higher in infants with eczema at three (OR 23·1, 95% CI 12·3-43·6) or two (OR 6·5, 95% CI 4·3-9·9) visits vs. one visit only. At 12 months, 156/329 (47·4%) fulfilled the UKWP and/or H&R criteria; 27 (8%) fulfilled the UKWP criteria only and 65 (20%) only the H&R criteria. Of the 129 infants who fulfilled the H&R criteria, 44 (34·1%) did not meet the itch criterion. CONCLUSIONS Used in combination and at multiple timepoints, the UKWP and H&R criteria for AD may be useful in clinical research but may have limited value in most other clinical settings.

Abstract
Psoriasis and atopic dermatitis (AD) are two common chronic inflammatory skin diseases. Although showing different etiology and clinical manifestations, patients with either disease suffer from low health-related quality of life due to pruritus (dermal itch). Recent studies have revealed that more than 85% of psoriasis patients suffer from pruritus, and it is also the dominating symptom of AD. However, as this is a non-life treating symptom, it was partly neglected for years. In this review, we focus on current findings as well as the impact and potential treatments of pruritus in these two skin diseases. We first distinguish the type of itch based on involved mediators and modulators. This clear delineation between the types of pruritus based on involved receptors and pathways allows for precise treatment. In addition, insights into recent clinical trials aimed to alleviate pruritus by targeting these receptors are presented. We also report about novel advances in combinatorial treatments, dedicated to the type of pruritus linked to a causal disease. Altogether, we suggest that only a focused treatment tailored to the primary disease and the underlying molecular signals will provide fast and sustained relief of pruritus associated with psoriasis or AD.

Abstract
An artificial intelligence algorithm to detect mycosis fungoides (MF), psoriasis (PSO), and atopic dermatitis (AD) is demonstrated. Results showed that 10 s was consumed by the single shot multibox detector (SSD) model to analyze 292 test images, among which 273 images were correctly detected. Verification of ground truth samples of this research come from pathological tissue slices and OCT analysis. The SSD diagnosis accuracy rate was 93%. The sensitivity values of the SSD model in diagnosing the skin lesions according to the symptoms of PSO, AD, MF, and normal were 96%, 80%, 94%, and 95%, and the corresponding precision were 96%, 86%, 98%, and 90%. The highest sensitivity rate was found in MF probably because of the spread of cancer cells in the skin and relatively large lesions of MF. Many differences were found in the accuracy between AD and the other diseases. The collected AD images were all in the elbow or arm and other joints, the area with AD was small, and the features were not obvious. Hence, the proposed SSD could be used to identify the four diseases by using skin image detection, but the diagnosis of AD was relatively poor.

Abstract
BACKGROUND While the majority of children with a chronic itchy rash suffer from atopic dermatitis (AD) and other forms of dermatitis, psoriasis is in the differential diagnosis. Certain patterns such as guttate and napkin psoriasis are accepted as classic paediatric psoriasis (PP); however, there are many patients who do not fit these classic forms of PP nor fulfil the accepted criteria for AD. 'Psoriasiform dermatitis' (PD) is a term that has been used for these patients; however, it has not been formally defined. Identification of this group of patients, who although not having the typical clinical features of psoriasis, respond well to psoriasis-specific treatment, may assist treatment decisions for these patients. AIM To describe PD and compare it with typical PP. METHODS Patients with classic PP (n = 109) were compared with a control group with AD (n = 449) and assessed for 21 clinical features associated with PP. Multivariate nonlinear regression analyses determined which features best separated the groups. Patients with dermatitis who demonstrated any of these 21 features (n = 43), which were used to diagnose PD, were then compared with the PP and AD groups. They were managed with psoriasis-specific treatment and Psoriasis Area and Severity Index (PASI) was recorded. RESULTS Of the 21 clinical features, 12 were found to clearly separate the classic PP and AD groups. Using the eight most significant (P < 0.0001) features, we found these two groups clearly separated at a score of 3 out of 8. Children with PD with ≥ 4 of these features responded well to treatment for psoriasis with a mean reduction of PASI by 85% at 6 weeks. CONCLUSIONS We found that patients with dermatitis who have ≥ 4 psoriasis-associated features may have a condition that has been previously alluded to but not defined in the literature, 'psoriasiform dermatitis'. Treatments usually reserved for patients with psoriasis appear to be effective in these patients.

Abstract
Hyaluronic acid (HA), a major component of extracellular matrix has been widely applied in pharmaceutical and cosmetic industries due to its reported pharmacological properties. Various types of HA drug delivery system including nanoparticles, cryogel-based formulations, microneedle patches, and nano-emulsions were developed. There are studies reporting that several HA-based transdermal delivery systems exhibit excellent biocompatibility, enhanced permeability and efficient localized release of anti-psoriasis drugs and have shown to inhibit psoriasis-associated skin inflammation. Similarly HA is found in abundant at epidermis of atopic dermatitis (AD) suggesting its role in atopic AD pathology. Anti-allergenic effect of atopic eczema can be achieved through the inhibition of CD44 and protein kinase C alpha (PKCα) interaction by HA. Herein, we aim to evaluate the current innovation on HA drug delivery system and the other potential applications of HA in inflammatory skin diseases, focusing on atopic dermatitis and psoriasis. HA is typically integrated into different delivery systems including nanoparticles, liposomes, ethosomes and microneedle patches in supporting drug penetration through the stratum corneum layer of the skin. For instance, ethosomes and microneedle delivery system such as curcumin-loaded HA-modified ethosomes were developed to enhance skin retention and delivery of curcumin to CD44-expressing psoriatic cells whereas methotrexate-loaded HA-based microneedle was shown to enhance skin penetration of methotrexate to alleviate psoriasis-like skin inflammation. HA-based nanoparticles and pluronic F-127 based dual responsive (pH/temperature) hydrogels had been described to enhance drug permeation through and into the intact skin for AD treatment.

Background The purpose of this study was to gather information on the current assessment and management of patients with moderate-to-severe AD in routine daily practice. Methods A cross-sectional two-round Delphi survey with the participation of dermatologists and allergologists throughout Spain was conducted. They completed a 46-item questionnaire, and consensus was defined when responses of ≥80% of participants coincided in the categories of a 5-point Likert scale for that item. Results A total of 105 specialists (aged 40–59 years) completed the two rounds. Participants agreed regarding the consideration of AD as a multifaceted disease and the differences in clinical presentation of AD according to the patient's age. It is recommendable to perform a skin biopsy to exclude early stage T-cell cutaneous lymphoma, psoriasis, or dermatitis herpetiformis, among others (99.1%). Also, consensus was reached regarding the use of the SCORAD index to quantify the severity of the disease (86.7%), the use of wet wraps to increase the effect of topical corticosteroids (90.4%), the usefulness of proactive treatment during follow-up (85.6%) and tacrolimus ointment (91.2%) to reduce new flares, and the fact that crisaborole is not the treatment of choice for severe AD (92.4%). AD was not considered a contraindication for immunotherapy in patients with allergic respiratory diseases (92.4%). In patients with severe AD, the use of immune response modifier drugs (97.6%) or phototherapy (92.8%) does not sufficiently cover their treatment needs. Consensus was also obtained regarding the role of the new biologic drugs (93.6%) targeting cytokines involved in the Th2 inflammatory pathway (92.0%) and the potential role of dupilumab as first-line treatment (90.4%) in moderate-to-severe AD patients. Conclusion This study contributes a reference framework to the care of AD patients. There is no diagnostic test or biomarkers to direct treatment or to assess the severity of the disease, and many therapeutic challenges remain.

Abstract
Atopic dermatitis (AD) is a predominant and deteriorating chronic inflammation of the skin, categorized by robust burning and eczematous lacerations in diverse portions of the body. AD affects about 20% of both offspring and adults worldwide. The pathophysiology of AD combines environmental, hereditary, and immunological aspects, together with skin barrier dysfunction. The procedures used to prevent the disease are the everyday usage of creams to support the restoration of the epidermal barrier. The classical treatments include the use of topical corticosteroids as a first-line therapy, but also calcineurin inhibitors, antihistamines, antibiotics, phototherapy, and also immunosuppressant drugs in severe cases of AD. Topical drug delivery to deeper skin layers is a difficult task due to the skin anatomic barrier, which limits deeper penetration of drugs. Groundbreaking drug delivery systems, based on nanoparticles (NPs), have received much attention due to their ability to improve solubility, bioavailability, diffusion, targeting to specific types of cells, and limiting the secondary effects of the drugs employed in the treatment of AD. Even so, additional studies are still required to recognize the toxicological characteristics and long-term safety of NPs. This review discusses the current classical pharmacotherapy of AD against new nanoparticle skin delivery systems and their toxicologic risks.

Abstract
Atopic dermatitis (AD) is the most common chronic inflammatory skin disorder of childhood. Underlying factors that contribute to AD are impaired epithelial barrier, alterations in the lipid composition of the skin, immunological imbalance including increased Th2/Th1 ratio, proinflammatory cytokines, decreased T regulatory cells, genetic mutations, and epigenetic alterations. Atopic dermatitis is a multifactorial disease with a particularly complicated pathophysiology. Discoveries to date may be considered the tip of the iceberg, and the increasing number of studies in this field indicate that there are many points to be elucidated in AD pathophysiology. In this review, we aimed to illustrate the current understanding of the underlying pathogenic mechanisms in AD, to evaluate available treatment options with a focus on recently discovered therapeutic agents, and to determine the personal, familial, and economic burdens of the disease, which are frequently neglected issues in AD. Currently available therapies only provide transient solutions and cannot fully cure the disease. However, advances in the understanding of the pathogenic mechanisms of the disease have led to the production of new treatment options, while ongoing drug trials also have had promising results.

Abstract
As the first targeted systemic agent for the treatment of moderate to severe atopic dermatitis (AD), dupilumab represents a novel therapeutic opportunity for both patients and providers. However, a subset of patients receiving dupilumab are either partial responders who exhibit some improvement in Investigator's Global Assessment score but not sufficient to meet the primary endpoint, or are non-durable responders who achieve therapeutic endpoint with subsequent partial loss of efficacy. We propose a therapeutic algorithm for the management of dupilumab partial responders and non-durable responders that involves maximizing topical therapy, seeking alternative diagnoses, and using dupilumab in conjunction with traditional systemic immunosuppressive agents. With a number of targeted agents for AD in the drug development pipeline, we encourage patients who do not have an adequate response to dupilumab to remain patient and optimistic as the arsenal of AD treatment modalities continues to expand.

Abstract
BACKGROUND Atopic dermatitis is a chronic inflammatory skin disease that affects up to 13% of children and 10% of adults in the United States. Among patients and their families, atopic dermatitis has a considerable effect on quality of life and represents a substantial economic burden. OBJECTIVE To describe the impact and challenges of atopic dermatitis and to provide nondermatologists in the healthcare community an enhanced understanding of atopic dermatitis to facilitate treatment and pharmacy benefit discussions. DISCUSSION Atopic dermatitis is a heterogeneous disease, and its diagnosis is hampered by a lack of objective diagnostic criteria. The current management guidelines address the distinct clinical phenotypes as a single disease and do not incorporate recent clinical advances, such as the targeting of specific inflammatory processes. The treatment guidelines for atopic dermatitis are complex and challenge healthcare providers, patients, and caregivers. Novel treatments can provide additional therapeutic options for patients with atopic dermatitis. CONCLUSIONS Treatment options for atopic dermatitis are expanding with the development of novel anti-inflammatory therapies. An increased understanding of these advancements is necessary to optimize care for patients with atopic dermatitis.

Abstract
Atopic dermatitis (AD) is a common inflammatory skin disease characterized by intensely pruritic lesions. The prevalence of atopic dermatitis is increasing in developing regions, including Africa and the Middle East. However, these regions are underrepresented in the dermatology literature, and a better understanding of the growing burden of atopic dermatitis in Africa and the Middle East is necessary. Herein, we summarize current knowledge on atopic dermatitis epidemiology, disease burden, and treatment options in Africa and the Middle East, highlighting the unmet needs of patients in these regions. With these needs in mind, we provide clinical recommendations for appropriate management of atopic dermatitis in Africa and the Middle East. FUNDING: Pfizer Inc.

Abstract
BACKGROUND/OBJECTIVES Childhood-onset psoriasis is a common skin disorder that has recently received increasing attention, particularly because of its significant medical, social, financial, and psychological burdens and its associated comorbidities. With limited data available and lack of standardized management guidelines for pediatric psoriasis, an expert panel desired to provide an updated critical overview and practical guidance for management of the affected population. METHODS A panel of pediatric dermatologists with extensive experience in pediatric psoriasis defined and prioritized a core set of topics, performed an English-language literature review, prepared critical evaluations and presentations of topic areas, and carried out a consensus meeting and follow-up consensus manuscript. RESULTS The summation of evolving perspectives in pediatric psoriasis includes epidemiology and natural history of the disease, precipitating factors and comorbidities, quality of life and burden of disease, clinical features and disease presentation, differential diagnosis, pathogenesis and treatment, including topical, photo, and systemic therapies. CONCLUSION Pediatric psoriasis is an important immune-mediated inflammatory skin disease with potential for significant impact on affected individuals and their caregivers. Current state-of-the-art care is based primarily on experience and expert consensus, but pediatric data are accumulating and therapeutic options are rapidly evolving.

Abstract
Atopic dermatitis (AD), or eczema, is a chronic inflammatory skin condition characterized by relapsing pruritic and dry, scaly lesions. AD affects 10% to 20% of children in the United States and significantly affects the quality of life of patients and their families. Primary care providers (PCPs) are often the first point of contact for the management of AD symptoms. As many as 70% of patients with mild to moderate disease can be managed by a PCP, underscoring the need for these providers to understand basic AD pathophysiology and current standards of care. This article will discuss the basic principles of AD diagnosis and management that PCPs need to optimize patient care, including AD pathogenesis, appropriate use of currently available topical therapies, basic skin care practices, and patient/caregiver counseling points.
