The prevalence of atopic dermatitis beyond childhood: A systematic review and meta-analysis of longitudinal studies.
Ontology highlight
ABSTRACT: Background
There are sparse and conflicting data regarding the long-term clinical course of atopic dermatitis (AD). Although often described as a childhood disease, newer population-based estimates suggest the prevalence of pediatric and adult disease may be similar.Methods
Our objective was to determine whether there is a decline in the prevalence of AD in population-based cohorts of patients followed longitudinally beyond childhood. We conducted a systematic review and meta-analysis including studies assessing AD prevalence across 3 or more points in time. The primary outcome was weighted overall risk difference (percentage decrease in AD prevalence).Results
Of 2080 references reviewed, 7 studies with 13 515 participants were included. Participants were assessed at 3-6 time points, ranging from age 3 months to 26 years. The percentage decrease in prevalence after age 12 was 1%, which was not significantly different from zero (95% confidence interval -2%-5%). Similar results were found with other age cut-offs.Conclusion
The prevalence of AD in longitudinal birth cohort studies is similar in childhood and adolescence/early adulthood.

Project description:ProblemTo determine the safety and efficacy of topical corticosteroid versus vehicle/moisturizer in children under 2 years old (<2 y).Eligibility criteriaA systematic review and meta-analysis searching PubMed MEDLINE, Embase, Web of Science, Cochrane Database of Controlled Trials, Cochrane Database of Systematic Reviews, DARE, NHS Economic Evaluation, CINAHL, GREAT, and Clinicaltrials.gov. We selected randomized controlled trials (RCTs) comparing topical corticosteroids to vehicle/moisturizer and included children <2 y. Two authors extracted data.SampleOnly one study limited analyses to children <2 y, so our review included participants older than 2 years. Twelve RCTs were included with 2224 participants. Ten studies were industry-sponsored.ResultsThe proportion of responders to topical corticosteroid across studies was 0.65 (95% CI, 0.54-0.74), as compared to vehicle/moisturizer 0.32 (95% confidence interval (CI), 0.20-0.48). The proportion of adverse events were similar between groups (topical steroids 0.17 (95% CI, 0.08-0.33) vs. vehicle/moisturizer 0.12 (CI 0.02-0.42)). High heterogeneity in treatment response occurred across studies that could not be explained by potential moderators. Mild adrenal suppression occurred in 4 of 157 measured participants (3%) receiving topical corticosteroids. Limitations include the few RCTs on this topic, the inclusion of participants >2 y and outcome measures and reporting methods rarely met CONSORT guidelines.ConclusionsTopical corticosteroids trended to being more effective and equally safe to vehicle/moisturizers, but generalizability is limited given the dearth of well-designed studies focused on children <2 y. Adverse events from vehicle/moisturizer may be greater than topical corticosteroid due to under treatment.ImplicationsFurther work is needed in this age group.

Project description:The lack of standardized nomenclature for atopic dermatitis (AD) creates unnecessary confusion for patients, healthcare providers, and researchers. It also negatively impacts accurate communication of research in the scientific literature. We sought to determine the most commonly used terms for AD.A systematic review of the MEDLINE, EMBASE, and LILACS (1945-2016) for the terms AD, atopic eczema (AE), and multiple other eczematous disorders.In MEDLINE, 33 060 were identified, of which 21 299 (64.4%) publications used the term 'AD', 15 510 (46.9%) 'eczema', and only 2471 (7.5%) AE. Most of these publications used the term AD (82.0%) or eczema (70.8%) without additional nomenclature; only 1.2% used AE alone. Few publications used the terminology 'childhood eczema', 'flexural eczema', 'infantile eczema', 'atopic neurodermatitis', or 'Besnier's prurigo'. AD was rarely used until the late 1970s, after which it became the most commonly used of the three terms and continuously increased until 2015. Atopic eczema decreased between 2008 and 2015. Atopic dermatitis was the most commonly used term in studies across almost all publication types, languages, and journals.Atopic dermatitis is the most commonly used term and appears to be increasing in popularity. Given that eczema is a nonspecific term that describes the morphological appearance of several forms of dermatitis, we strongly suggest the use of a more specific term, AD, in publications, healthcare clinician training, and patient education. Support from researchers, reviewers, and editors is key to success.

Project description:Previous studies found conflicting results about whether childhood atopic dermatitis (AD) persists into adulthood.We sought to determine persistence rates and clinical factors associated with prolonged AD.A systematic review was performed in MEDLINE, EMBASE, Scopus, GREAT, LILACS, Web of Science, Academic Search Complete, and Cochrane Library. Meta-analysis was performed using Kaplan-Meier plots and random-effects proportional hazards regression.In total, 45 studies including 110,651 subjects spanning 434,992 patient-years from 15 countries were included. In pooled analysis, 80% of childhood AD did not persist by 8 years and less than 5% persisted by 20 years after diagnosis (mean ± SE: 6.1 ± 0.02 years). Children with AD that persisted already for more than 10 years (8.3 ± 0.08 years) had longer persistence than those with 3 (3.2 ± 0.02 years) or 5 (6.8 ± 0.06 years) years of persistence. Children who developed AD by age 2 years had less persistent disease (P < .0001). Persistence was greater in studies using patient-/caregiver-assessed versus physician-assessed outcomes, female versus male patients (P ? .0006), but not in those with sensitivity to allergens (P = .90). Three studies found prolonged persistence with more severe AD.Some studies did not capture recurrences later in life.Most childhood AD remitted by adulthood. However, children with already persistent disease, later onset, and/or more severe disease have increased persistence.

Project description:BackgroundTreatment preference research can support shared and informed decision making for currently available atopic dermatitis (AD) treatments, and simultaneously guide research and development for future therapies. In this systematic literature review, we aimed to provide an overview of preferences for AD treatments.MethodsThis systematic literature review was conducted in the Medline and Embase (via Ovid) databases, supplemented by manual searching. Quantitative research published from 2010 to September 2023 that investigated preferences for AD treatments were included. Quality assessment was conducted by using the purpose, respondents, explanation, findings, significance checklist, and a checklist developed by the Professional Society for Health Economics and Outcomes Research.ResultsIn total, 207 references were screened after removing duplicates and 15 studies were included. Most studies were conducted in the US, followed by European countries. On average, people directly or indirectly affected by AD rate efficacy and treatment-related risk as the most important criteria when choosing an AD therapy. Participants are willing to increase risks in order to have a higher chance of achieving a certain benefit, e.g. reduction in itch or clearer skin. Participants have preferences for different modes of administration. On average, 68% (all full-text studies) and 87% (only discrete choice experiments [DCEs]) of quality criteria per reference were rated as fulfilled. DCEs received generally higher quality assessment scores than non-DCEs.ConclusionsThis review revealed that AD treatment preference research is limited. Diverse study designs hampered comparison and synthesis of the results. We recommend conducting more DCEs in this field to increase the likelihood of AD patients receiving the therapy that best fits their individual needs and preferences.Clinical trials registrationThis protocol was published in PROSPERO (ID: CRD42023468757).

Project description:Atopic dermatitis is a chronic inflammatory disease that can arise during the first months of life or at maturity and have a significant negative impact on the quality of life. The main pathogenic mechanism is the breakdown of cutaneous barrier integrity, which is associated with systemic inflammatory immunologic disorders. Atopic dermatitis involves numerous immunologic, allergic, respiratory, and ophthalmologic comorbidities that develop through similar intricate pathogenic phenomena. The atopic march represents the evolution in time of various allergic diseases, of which food allergies often cause the first manifestations of atopy, even from a very young age. Chronic inflammation translated through specific markers, next to increased immunoglobulin E (IgE) serum levels and heterogenous clinical manifestations, argue for the inclusion of atopic dermatitis in the systemic disease category.

Project description:Tobacco exposure might be a modifiable risk factor for atopic dermatitis (AD).We examine the association between AD and exposure to tobacco smoke.We performed a systematic review and meta-analysis of observational studies (n = 86) in MEDLINE, EMBASE, Scopus, and Cochrane Library (1823-2015). Quality of evidence was assessed using the Newcastle-Ottawa Scale (NOS). A meta-analysis was performed using random-effects models to estimate pooled odds ratios (OR). Subset analyses were performed for different ages (children, adult), regions, study designs (cross-sectional, longitudinal), study sizes (<5000, ?5000), study quality (NOS score <6, ?6), and amount of smoking (mild, extensive).A diagnosis of AD was associated with higher odds of active smoking (OR 1.87, 95% confidence interval 1.32-2.63) and exposure to passive smoke (OR 1.18, 95% confidence interval 1.01-1.38), but not maternal smoking during pregnancy (OR 1.06, 95% confidence interval 0.80-1.40). The association between active smoking and AD remained significant in children and adults, all continents studied, and study sizes, but all were cross-sectional designs and had NOS score 6 or greater. Passive smoke was associated with AD in children and adults, cross-sectional studies, South/Central American and African studies, study size less than 5000, and NOS score less than 6.AD severity and distribution were not assessed.Active and passive exposure to smoke are associated with increased AD prevalence.

Project description:BackgroundRoutinely collected electronic health data obtained for administrative and clinical purposes are increasingly used to study atopic dermatitis (AD). Methods for identifying AD patients in routinely collected electronic health data differ, and it is unknown how this might affect study results.ObjectivesTo evaluate how patients with AD have been identified in studies using routinely collected electronic health data, to determine whether these methods were validated and to estimate how the method for identifying patients with AD affected variability in prevalence estimates.MethodsWe systematically searched PubMed, Embase and Web of Science for studies using routinely collected electronic health data that reported on AD as a primary outcome. Studies of localized AD and other types of dermatitis were excluded. The protocol for this review was registered in PROSPERO (CRD42016037968).ResultsIn total, 59 studies met eligibility criteria. Medical diagnosis codes for inclusion and exclusion, number of occasions of a code, type of provider associated with a code and prescription data were used to identify patients with AD. Only two studies described validation of their methods and no study reported on disease severity. Prevalence estimates ranged from 0·18% to 38·33% (median 4·91%) and up to threefold variation in prevalence was introduced by differences in the method for identifying patients with AD.ConclusionsThis systematic review highlights the need for clear reporting of methods for identifying patients with AD in routinely collected electronic health data to allow for meaningful interpretation and comparison of results.

Project description:PurposeQuestionnaire-based diagnostic criteria for atopic dermatitis (AD) have been proposed to detect the major group of AD with flexural dermatitis. We aimed to develop novel, questionnaire-based diagnostic criteria for childhood AD, which can detect more comprehensive AD including non-flexural type.MethodsThe draft version of questionnaire to detect childhood AD was prepared to be used for preliminary hospital- (n=1,756) and community-based (n=1,320) surveys. From analysis, the Reliable Estimation of Atopic dermatitis of ChildHood (REACH) was derived and verified in derivation (n=1,129) and validation (n=1,191) sets by community-based surveys.ResultsThe REACH consists of 11 questions including 2 major and 9 minor criteria. AD is diagnosed as the major group of 'eczema on the antecubital or popliteal fossa' to fulfill the 2 major criteria (2M), and the minor group of 'eczema on the non-antecubital or popliteal fossa' to fulfill the 1 major plus 4 or more minor criteria (1M+4m). In the validation set, the overall 1-year AD prevalence by the REACH was estimated as 12.3% (95% CI, 10.5%-14.2%), and the REACH showed a sensitivity of 75.2%, a specificity of 96.1%, and an error rate of 6.4%. The REACH demonstrated better diagnostic performance than the ISAAC in terms of the number of misclassification (10.0%).ConclusionsWe propose the REACH as new full, questionnaire-based diagnostic criteria for childhood AD in epidemiological surveys. Further studies are warranted to validate the REACH in different populations or countries in the context of large-scale, epidemiological surveys.

Project description:INTRODUCTION:There are numerous new systemic treatments for atopic dermatitis in various stages of development and most are being compared with placebo rather than active comparators. In order to understand the relative efficacy and safety of existing and new treatments for atopic dermatitis, robust mixed comparisons (ie, direct and indirect) would be beneficial. To address this gap, this protocol describes methods for a systematic review and network meta-analysis of systemic treatments for atopic dermatitis. METHODS AND ANALYSIS:We will update the search of a previous systematic review, including searches of the Cochrane Central Register of Controlled Trials, MEDLINE, Embase, Latin American and Caribbean Health Science Information database and the Global Resource of EczemA Trials database in addition to clinical trial protocol registries. Title, abstract and full paper screening as well as data extraction will be conducted in duplicate by independent researchers. Primary outcomes include efficacy with regards to clinician-reported signs and patient-reported symptoms and safety with regards to withdrawal from treatment due to adverse events and the occurrence of serious adverse events. Secondary outcomes will include change in quality of life and itch severity. Where possible and appropriate, network meta-analysis will be performed for each outcome using a random-effects model within a Bayesian framework. If appropriate, the review will be transitioned to a living review with continuous updating of the analysis. ETHICS AND DISSEMINATION:Dissemination in a peer-reviewed scientific journal is planned.

Project description:BackgroundAtopic dermatitis (AD) is a chronic, inflammatory skin disorder characterised by intense itch and eczematous lesions. Rising prevalence of AD has been observed worldwide including in Asia. Understanding the risk factors associated with AD may explain its pathogenicity and identify new preventive strategies and treatments. However, AD-associated risk factors and comorbidities specific to Asia have not been systematically reviewed.MethodsWe performed a systematic review in accordance with the Preferred Reporting Item for Systematic Review and Meta-Analyses (PRISMA) guidelines and summarised epidemiological studies investigating personal, family, and environmental factors and comorbidities associated with AD in Asia. Significant factors were assessed if they can be altered through lifestyle practices and further classified into non-modifiable and modifiable factors. Meta-analysis using the random-effect model was also conducted to provide an overall estimate for several significant factors.ResultsWe identified a total of 162 epidemiological studies conducted in Asia. Among non-modifiable factors, a family history of atopic diseases was the most reported, suggesting the involvement of genetics in AD pathogenesis. Among modifiable factors, the results of meta-analyses revealed maternal smoking as the strongest risk factor with a pooled odds ratio (OR) of 2.95 (95% CI, 2.43-3.60), followed by active smoking (pooled OR, 1.91, 95% CI, 1.41-2.59).ConclusionWhile a family history may aid clinicians in identifying high-risk individuals, literature has long suggested the importance of gene-environment interaction. This review identified several modifiable factors including medical treatments, indoor and outdoor environmental exposure, and personal and family lifestyle specific to Asia. Based on the meta-analyses performed, prevention strategies against AD may start from changing personal and family lifestyle choices, especially smoking habits.
