Meta-Analysis Review
Atopic dermatitis (AD) is a type 2 chronic skin disorder associated with systemic and psychosocial comorbidities decreasing the quality of life for many patients. Dupilumab, a human monoclonal antibody that blocks interleukins IL-4 and IL-13, is a recently added systematic treatment option with an emerging evidence base. Here, we assessed the safety and efficacy of dupilumab in patients with AD. We conducted a systematic review and meta-analysis of placebo-controlled randomized clinical trials evaluating the safety and efficacy of dupilumab on AD-related outcomes including clinical symptoms, quality of life and adverse events (AE). Subgroup analysis was further performed in adults and children/adolescents. Fourteen trials were included: twelve in adults (n = 3,817) and two in children/adolescents (n = 618). Dupilumab decreased the Eczema Area Severity Index (EASI) score [standardized mean difference (SMD) = -0.98; 95% confidence interval (95% CI) = (-1.09, -0.88)], the percent change difference in Scoring Atopic Dermatitis (SCORAD) [mean difference (MD) = -31.56, 95% CI = (-33.75, -29.36)], and in pruritus Numeric Rating Scale (pNRS) [MD = -29.24, 95% CI = (-32.11, -26.37)]. It also achieved a reduction of at least ≥75% in the EASI score [Risk Ratio (RR) = 2.89, 95% CI = (2.47, 3.38)], the Investigator's Global Assessment (IGA) score ≤1 [RR = 3.47, 95% CI = (2.96, 4.06)] and eight additional endpoints with no signs of increased AE compared to placebo. In subgroup analysis, the results were concordant for both groups. Dupilumab improved clinical symptoms and quality of life in adults and children/adolescents with a safety profile comparable to placebo.

Meta-Analysis
The aim of this study was to compare the efficacies of systemic treatments with dupilumab, tralokinumab and Janus kinase inhibitors for moderate-to-severe atopic dermatitis. A systematic review following Preferred Reporting Items for Systemic Reviews and Meta-Analyses (PRISMA) guidelines was performed using Medline, EMBASE and Cochrane library. All randomized controlled trials investigating the efficacy of systemic treatments for moderate-to-severe atopic dermatitis in adults were included. Primary outcomes were the proportion of patients with atopic dermatitis achieving 50%, 75%, and 90% improvement in Eczema Area and Severity Index (EASI) score after dupilumab, tralokinumab or Janus kinase inhibitors. Nineteen studies totalling 6,444 patients were included. In monotherapy studies, upadacitinib 30 mg once daily had the numerically highest efficacy regarding EASI-50, EASI-75 and EASI-90. In combination therapy studies with topical corticosteroids, dupilumab 300 mg once every other week had highest efficacy regarding EASI-50, and abrocitinib 200 mg once daily had the highest score regarding EASI-75 and EASI-90. Analysis provided evidence that dupilumab, tralokinumab and Janus kinase inhibitors all had an acceptable efficacy profile and resulted in clinically relevant improvements in EASI score. Furthermore, upadacitinib and abrocitinib seem to have great potential to treat patients with atopic dermatitis. However, further studies are needed to determine the long-term efficacy of Janus kinase inhibitors in adults with moderate-to-severe atopic dermatitis.

Review
The nipple is the focal point of the human breast and serves important physiological, sexual, and aesthetic purposes. It can be affected by atopic, irritant, and allergic contact eczema, which often reduce the patient's quality of life. The objective of this article is to discuss the different types of nipple eczema and highlight relevant differential diagnoses and treatment options. A systematic search of PubMed was conducted to identify and critically appraise the existing literature on the topic. All articles on nipple eczema were considered eligible, regardless of publication date, language or study design. A final of 33 manuscripts on nipple eczema remained. The scarce literature and the limited number of high-quality manuscripts impedes provision of structured data on nipple eczema. To securely reach the educative value of this manuscript, the systematic review was combined with a manual databank search and selected manual search of textbooks. The differential diagnosis of nipple eczema encompasses among others nipple psoriasis, nipple candidiasis and Paget's disease. In case of diagnostic uncertainty, swabs or biopsies are indicated. Treatment of nipple eczema needs to rapidly control the signs and symptoms of the disease, since it can have a negative effect on quality of life and can lead to premature arrest of breastfeeding. The key treatment step is starting with topical corticosteroids or calcineurin inhibitors, both of which are considered safe during lactation. Avoidance of provoking factors, such as repetitive friction, chemical agents, or allergens, can help. The use of nipple protection devices can be proposed for nursing women and sometimes adjusting of latch/suck positioning during breastfeeding is needed. Furthermore, patients should be advised to moisturize the nipple intensively and to switch to emollient wash products. Warm water compresses, black tea compresses or commercially available tannin containing topicals can provide comfort.

INTRODUCTION
The comparative efficacy of targeted systemic therapies for moderate to severe atopic dermatitis (AD) has not been systematically assessed using recent phase 3 data. This network meta-analysis assesses the comparative efficacy of targeted systemic therapies without the addition of topical corticosteroids (TCS) and/or topical calcineurin inhibitors (TCI) in adults with moderate to severe AD.
METHODS
The systematic literature review searched through 17 May 2021 for phase 3/4 trials with upadacitinib, interleukin-4 (IL-4), interleukin-13 (IL-13), or JAK inhibitors compared with placebo or active intervention for adults and adolescents with moderate to severe AD with inadequate response to TCS/TCI or for whom TCS/TCI was medically inadvisable, without restrictions on year or region. Researchers assessed data using PRISMA guidelines. The proportion of patients achieving trial co-primary endpoints [Investigator Global Assessment (IGA) score of 0 or 1 (clear or almost clear) and reduction of ≥ 2 points from baseline; proportion of patients achieving Eczema Area and Severity Index (EASI) improvement ≥ 75% from baseline (EASI-75)]; EASI improvement ≥ 90% from baseline (EASI-90); and ≥ 4-point improvement on Pruritus Numerical Rating Scale from baseline (ΔNRS ≥ 4) were evaluated using Bayesian network meta-analysis.
RESULTS
Of 3415 initially identified records, network meta-analysis (NMA) ultimately included 6 records representing 9 unique studies. Two upadacitinib trials were also included. Eleven clinical trials including 6254 patients were analyzed. Upadacitinib 30 mg daily was the most efficacious therapy across all endpoints at the primary endpoint (week 12 or 16) and at earlier timepoints, followed by upadacitinib 15 mg daily and abrocitinib 200 mg daily.
DISCUSSION
Many factors need to be considered for treatment selection for AD. These findings can help healthcare providers when personalizing a patient's treatment.
CONCLUSION
Upadacitinib 30 mg daily, upadacitinib 15 mg daily, and abrocitinib 200 mg daily may be the most efficacious targeted systemic therapies over 12-16 weeks of therapy in AD.

Meta-Analysis
BACKGROUND
Dupilumab, the first biological drug to be approved for the treatment of moderate to severe atopic dermatitis in adolescents and adults, has shown good efficacy and safety in clinical trials.
OBJECTIVE
To evaluate real-world data on the efficacy and safety of dupilumab in atopic dermatitis.
METHODS
PubMed and EMBASE were searched for observational studies with data on efficacy, drug survival, and safety of dupilumab for the treatment of atopic dermatitis. Primary outcomes were mean percentage change in Eczema Area and Severity Index (EASI) score and proportion of atopic dermatitis patients achieving 50%, 75%, and 90% improvement in EASI score after dupilumab therapy.
RESULTS
Twenty-two unique studies encompassing 3303 atopic dermatitis patients were included. After 16 weeks of dupilumab therapy, the pooled proportion of patients achieving 50%, 75%, and 90% EASI score improvement was 85.1%, 59.8%, and 26.8%, respectively, and the weighted mean reduction in EASI score was 69.6%. Conjunctivitis was the most common adverse event, reported in a pooled proportion of 26.1%.
LIMITATIONS
Limited data in terms of size and follow-up time were available.
CONCLUSION
Real-world data show that dupilumab is a successful and well-tolerated therapy for atopic dermatitis, but ocular adverse events commonly occur. Registries are needed to monitor for adverse events.

Review
In recent years, the broadening understanding of the pathogenesis of atopic dermatitis (AD) has led to the development of novel therapeutic molecules, that target core inflammatory components of the disease. The Janus kinase (JAK)/signal transducer and activation of transcription (STAT) pathway constitutes the principal signaling cascade for a large number of cytokines and growth factors and is involved in intracellular signal transduction and subsequent regulation of gene transcription. Current knowledge suggests that the robust activation of the T-helper (Th)-2 [interleukin (IL)-4, IL-5, IL-13, IL-31] and Th22 (IL-22) immune responses in both skin and serum plays a pivotal role in the immunopathogenesis of AD especially at the acute stage, followed by a variable degree of Th1 (interferon-γ, tumor necrosis factor alpha) and Th17 (IL-17) activation in chronic disease. Of note, most of the aforementioned inflammatory cytokines utilize the JAK/STAT pathway for downstream signal transduction, explaining the emerging role of JAK inhibitors in the therapeutic armamentarium of AD. The present systematic review aims to discuss the involvement of JAK/STAT pathway in the pathogenesis of AD and summarize the clinical data available on the efficacy and safety of JAK inhibitors which have been used in the treatment of AD thus far.

Veterinary Dermatology Feb 2021Feline allergic skin disease and asthma occur regularly in small animal practice. (Review)
Review
BACKGROUND
Feline allergic skin disease and asthma occur regularly in small animal practice.
OBJECTIVES
To provide evidence-based recommendations for small animal practitioners on the treatment of feline atopic syndrome (FAS).
METHODS AND MATERIALS
The authors reviewed the literature available before February 2020, prepared a detailed evidence-based literature review and made recommendations based on the evaluated evidence.
RESULTS
Sixty-six papers and abstracts were identified describing treatment interventions for FAS and evaluated to establish treatment recommendations. For many treatment options, the papers were retrospective, open studies or case reports.
CONCLUSION AND CLINICAL RELEVANCE
In this review, there was good evidence for the efficacy of systemic glucocorticoids and ciclosporin, and limited evidence for the efficacy of topical glucocorticoids, oclacitinib and allergen-specific immunotherapy in feline atopic skin syndrome. Evidence pointed to low-to-moderate efficacy for antihistamines, fatty acids and palmitoyl ethanolamide. In feline asthma, there was good evidence for the efficacy of oral and inhaled glucocorticoids, and limited evidence of moderate efficacy for allergen-specific immunotherapy. Evidence supported low-to-moderate efficacy of mesenchymal stem cells, inhaled lidocaine and oclacitinib as treatments for feline asthma. For almost all therapeutic options (with the exception of glucocorticoids and ciclosporin), more randomised controlled trials are needed.

JAAD International Mar 2021Complementary and alternative medicine (CAM) treatments are growing in popularity as alternative treatments for common skin conditions. (Review)
Review
BACKGROUND
Complementary and alternative medicine (CAM) treatments are growing in popularity as alternative treatments for common skin conditions.
OBJECTIVES
To perform a systematic review and meta-analysis to determine the tolerability and treatment response to CAM treatments in acne, atopic dermatitis (AD), and psoriasis.
METHODS
PubMed/Medline and Embase databases were searched to identify eligible studies measuring the effects of CAM in acne, AD, and psoriasis. Effect size with 95% confidence interval (CI) was estimated using the random-effect model.
RESULTS
The search yielded 417 articles; 40 studies met the inclusion criteria. The quantitative results of CAM treatment showed a standard mean difference (SMD) of 3.78 (95% CI [-0.01, 7.57]) and 0.58 (95% CI [-6.99, 8.15]) in the acne total lesion count, a SMD of -0.70 (95% CI [-1.19, -0.21]) in the eczema area and severity index score and a SMD of 0.94 (95% CI [-0.83, 2.71]) in the scoring of atopic dermatitis score for AD, and a SMD of 3.04 (95% CI [-0.35, 6.43]) and 5.16 (95% CI [-0.52, 10.85]) in the Psoriasis Area Severity Index score for psoriasis.
LIMITATIONS
Differences between the study designs, sample sizes, outcome measures, and treatment durations limit the generalizability of data.
CONCLUSIONS
Based on our quantitative findings we conclude that there is insufficient evidence to support the efficacy and the recommendation of CAM for acne, AD, and psoriasis.

The British Journal of Dermatology Dec 2023Atopic dermatitis (AD) is the leading cause of the global burden from skin disease; no study has provided global and country-specific epidemiological estimates of AD.
BACKGROUND
Atopic dermatitis (AD) is the leading cause of the global burden from skin disease; no study has provided global and country-specific epidemiological estimates of AD.
OBJECTIVES
To quantify global, regional and country-specific estimates of the epidemiology of AD.
METHODS
A comprehensive search for epidemiological studies in AD was conducted in four electronic databases (PubMed, Embase, Web of Science and China National Knowledge Infrastructure). A Bayesian hierarchical linear mixed model was constructed to calculate epidemiological estimates of AD considering the heterogeneity of regions, countries, type of diagnoses and age strata.
RESULTS
In total, 344 studies met the inclusion criteria. Incidence varied substantially with the location and age of the surveyed participants. The global prevalence of AD and the population affected by AD were estimated to be 2.6% [95% uncertainty interval (UI) 1.9-3.5] and 204.05 million people, respectively. Around 101.27 million adults and 102.78 million children worldwide have AD, corresponding to prevalence rates of 2.0% (95% UI 1.4-2.6) and 4.0% (95% UI 2.8-5.3), respectively. Females were more likely to suffer from AD than males: the global prevalence of AD in females was 2.8% (95% UI 2.0-3.7%) and affected 108.29 million people, while in males the corresponding estimates were 2.4% (95% UI 1.7-3.3%) and 95.76 million people.
CONCLUSIONS
Epidemiological AD data are lacking in 41.5% of countries worldwide. The epidemiology of AD varies substantially with age and sex and is distributed unequally across geographical regions.

INTRODUCTION
Numerous guidelines have been published for atopic dermatitis management in children in recent years. To date, the quality of the newest guidelines has not been appraised. This study aimed to identify and evaluate guidelines for the management of atopic dermatitis in children.
METHODS
We reviewed the literature retrieved from PubMed, Web of Science, Ovid, ScienceDirect, Embase, China National Knowledge Infrastructure, WanFang Data, and guidelines websites. Search period from January 1, 2016, to December 31, 2021. The following keywords were used for searching: "atopic dermatitis," "atopic eczema," "eczema," "guideline," and "consensus." The quality of the guidelines was assessed by two assessors using the Appraisal of Guidelines for Research & Evaluation II (AGREE II) instrument independently, and domain scores >60% were considered to have sufficient quality. The guideline recommendations were reviewed.
RESULTS
Nineteen guidelines were included in the study. Three guidelines had a graded A level, which was recommended for use in practice. Eleven guidelines had a graded B level, which was recommended for use in revision. The remaining five guidelines were rated with C level, which was not recommended. The average score of six domains of AGREE II was 64.76%, 48.53%, 42.35%, 73.83%, 32.23%, and 70.17%, respectively. A consistency test showed an intraclass correlation coefficient range of 0.497 (95% CI: 0.105, 0.705) to 0.970 (95% CI: 0.93, 0.987) based on the two assessors' test results for the guidelines.
CONCLUSIONS
Most guidelines were recommended for use with revision. No significant changes were observed in the primary management of atopic dermatitis in children compared to previous evidence. New biological agents and complementary alternative medicine are increasingly available, but the evidence for the treatment of atopic dermatitis in children is still limited.
