Abstract
Prior studies have found associations between atopic dermatitis (AD) and comorbidities, including depression, obesity, asthma, and allergic rhinitis. Although observational studies often cannot establish robust causality between potential risk factors and AD, Mendelian randomization minimizes confounding when exploring causality by relying on random allelic assortment at birth. In this study, we systematically reviewed 30 Mendelian randomization studies in AD. Body mass index, gut microbial flora, the IL-18 signaling pathway, and gastroesophageal reflux disease were among the causal factors for AD, whereas AD was causal for several medical conditions, including heart failure, rheumatoid arthritis, and conjunctivitis. These insights may improve preventive counseling in AD.

Park BG, Seul TW, Shin JJ, Son SW. Preliminary Clinical Study of the Effects and Safety of 308-nm Excimer Light Treatment in Patients with Atopic Dermatitis. Ann Dermatol 2023; 35:417-423. [PMID: 38086355 PMCID: PMC10733073 DOI: 10.5021/ad.22.223] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/18/2022] [Revised: 05/17/2023] [Accepted: 05/22/2023] [Indexed: 12/22/2023] Open
Abstract
BACKGROUND Atopic dermatitis (AD) is a common skin disease which, depending on its severity, can have a significant impact on the quality of life of affected individuals. In cases of severe AD, systemic immunomodulatory agents can be considered for treatment. However, the available treatment options for moderate AD are limited. According to previous reports, however, 308-nm excimer light is a potential treatment for localized, moderate AD. OBJECTIVE This study aimed to assess the clinical efficacy and safety of 308-nm excimer light in Korean adults with AD. METHODS This study included Korean patients aged over 19 years, who were diagnosed with AD by a dermatologist, with bilateral, symmetric, and eczematous lesions. The symmetrical lesions in each patient were treated as control-test pairs. Treatment with 308-nm excimer light was applied to the test lesion twice a week for 4 weeks. The severity of the eczema, trans-epidermal water loss, and epidermal capacitance were measured. RESULTS A total of 25 participants were enrolled in the study. After the first visit, two participants withdrew, whereas the remaining 23 completed the study. There was a statistically significant improvement in AD severity in the test group than in the control group (p<0.001). Skin barrier function also improved in the test than in the control group (p<0.01). CONCLUSION This study provides preliminary evidence for the use of 308-nm excimer light as a treatment option to improve symptoms and skin barrier function in moderately localized AD.

Abstract
ZusammenfassungDie atopische Dermatitis ist die häufigste chronisch‐entzündliche Hauterkrankung im Kindesalter. Einige Studien kamen zu dem Ergebnis, das Risiko für diese Erkrankung sei im städtischen Raum höher als im ländlichen. Wir haben die verfügbaren Studien systematisch untersucht und eine Meta‐Analyse durchgeführt, um Unterschiede im Risiko für atopische Dermatitis zwischen städtischem und ländlichem Raum zu erkennen. Die Suche in den Datenbanken Embase und MEDLINE wurde am 19. April 2021 durchgeführt. Einschlusskriterium war das Stichwort “Beobachtungsstudie”. Wir haben außerdem Subgruppenanalysen bezüglich Patientenalter, Publikationsjahr und Land durchgeführt. Insgesamt wurden bei der Datenbanksuche 2115 Studien aufgefunden, von denen letztlich 43 Studien mit insgesamt 1 728 855 Patienten in die Meta‐Analyse eingeschlossen wurden. Ein Wohnsitz im städtischen Raum war mit einem erhöhten Risiko für atopische Dermatitis assoziiert; die Odds Ratio war 1,56 (95 %‐Konfidenzintervall 1,43–1,71). Dieses signifikant erhöhte Risiko war nur bei Kindern zu beobachten (Odds Ratio 1,55, 95 %‐Konfidenzintervall 1,39–1,73), nicht jedoch bei Erwachsenen. Hier betrug die Odds Ratio 1,29 (95 %‐Konfidenzintervall 0,99–1,67). Das Risiko für atopische Dermatitis ist in den letzten Jahrzehnten angestiegen, wobei das Risiko in Entwicklungsländern mit einer Odds Ratio von 1,95 höher liegt als in Industrieländern (Odds Ratio 1,35). Unsere Studie bestätigt die Assoziation zwischen atopischer Dermatitis und dem Wohnsitz im städtischen gegenüber dem ländlichen Raum.

Abstract
Atopic dermatitis is the most common chronic inflammatory skin disease affecting children. Some studies have reported a higher risk of atopic dermatitis in urban areas than in rural areas. We systematically reviewed and carried out a meta-analysis to investigate the differences in the development of atopic dermatitis between urban and rural areas. The search was performed on April 19, 2021, using Embase and MEDLINE databases. Eligible for inclusion were observational studies. Subgroup analyses were performed for age, publication year, and country. We identified 2,115 studies, and 43 studies with 1,728,855 subjects were finally included. Urban residency was associated with an increased risk of atopic dermatitis, with an odds ratio of 1.56 (95% confidence interval, 1.43-1.71). A significantly increased risk was observed only in children, with an odds ratio of 1.55 (95% confidence interval, 1.39-1.73), but not in adults, with an odds ratio of 1.29 (95% confidence interval, 0.99-1.67). The risk has increased in recent decades, with a higher risk in developing countries (odds ratio, 1.95) compared to developed countries (odds ratio, 1.35). Our study provides evidence of an association between atopic dermatitis and urban compared to rural living.

Abstract
Atopic dermatitis (AD) is a chronic inflammatory skin condition associated with a significant disease burden in Korea. AD is highly prevalent among Korean children, adolescents, and adults, and can cause physical discomfort, psychological distress, and social isolation for those affected. Despite advances in our understanding of AD, there are still many unmet needs in diagnosing and managing the disease in Korea. One of the challenges in diagnosing AD is the lack of a definitive biomarker for AD in Korea, and there is a need for more effective, safe, and cost-effective treatments for AD. Therefore, finding out the current epidemiology, burden of AD, and how AD is currently being diagnosed in Korea and reviewing management options available in Korea will help resolve the unmet needs of AD patients in Korea. Addressing these and other unmet needs in AD management and diagnosis in Korea may improve outcomes for those affected by this challenging condition.

Abstract
Atopic dermatitis (AD) is a chronic inflammatory skin disease that is common in children and is increasing worldwide. This study aimed to identify differences in children's health behavior and social-emotional health status based on AD diagnosis at late school age. For this purpose, we conducted a descriptive survey using the 12th Panel Study on Korean Children data obtained in 2019. The data were analyzed using descriptive statistics, the Rao-Scott χ2 test, and a t-test using a complex sample analysis. A total of 1412 11-year-old Korean children participated in the study, of whom an estimated 8.2% were diagnosed with AD. In the children diagnosed with AD, the transition from exclusive breastfeeding to mixed feeding was later than that in children without AD (F = 5.71, p = 0.024), and the prevalence of AD in their parents was higher (F = 6.97, p = 0.014). Regarding health behaviors, the children diagnosed with AD had a higher intake frequency of protein (F = 5.41, p = 0.028) and vegetables (F = 6.09, p = 0.020). Regarding social-emotional health, subjective health status (F = 3.94, p = 0.026) and friend relationships (F = 2.95, p = 0.007) were lower in the children diagnosed with AD. These results, as preliminary data for interventions for school-aged children with AD, suggest that the difficulties of children's peer relationships should be considered and dealt with in further interventions.

Abstract
Atopic dermatitis is a chronically relapsing inflammatory skin condition that has profound impacts on quality of life of patients and their family. The aim of this study is to investigate the psychological stress in parents of children with atopic dermatitis in Korea, using data from the Korean National Health and Nutrition Examination Survey (KNHANES). This cross-sectional study included parents of participants under 19 years of age (970 with atopic dermatitis and 5,733 without atopic dermatitis after excluding those who meet the exclusion criteria) from the 2009 to 2012 KNHANES. The psychological stress state was evaluated with the following four questionnaire items: self-perception of stress, depressed mood, suicidal ideation, and diagnosis of depression by a physician. After adjusting for age, gender, education level, occupation, and marital status, logistic regression analyses indicated that mothers of children with atopic dermatitis had a higher frequency of stress perception (adjusted odds ratio (aOR) 1.46 (95% confidence interval (95% CI) 1.22-1.74), p < 0.01) and suicidal ideation (aOR 1.40 (95% CI 1.1-1.79), p < 0.01) than those without atopic dermatitis. In contrast, fathers of children with atopic dermatitis did not show a significant difference in all items compared with those of children without atopic dermatitis. Understanding the psychological stress in parents of children with atopic dermatitis is important for clinicians, since evaluation, management and support for parents, especially mothers, of children with atopic dermatitis are required.

Abstract
OBJECTIVE Atopic dermatitis (AD) is one of the common chronic diseases that occur in children and adolescents as a chronic relapsing pruritic inflammatory skin disease. This study investigated how AD is associated with stress and depressive symptoms in a large representative sample of adolescents in South Korea. METHODS The Korea Youth Risk Behavior Web-based Survey 2019 was used in this study (n = 57,069, weighted national estimates = 2,672,170). Multivariate logistic regression was used to determine significant associations between AD and mental health, measured by stress and depressive symptoms. Sub-group analysis was also conducted using various socio-economic variables. RESULTS Among the present sample, 6.5% of adolescents (n = 173,909) were diagnosed with AD in the past 12 months. After adjusting for other variables, AD diagnosis was associated with significantly higher odds of experiencing stress (OR = 1.43) and depressive symptoms (OR = 1.32) as compared to adolescents without AD. A similar trend is found in subgroup model analysis using socio-economic variables (ie, education levels, parent's income levels, and residence area). Specifically, female adolescents with AD, adolescents of low socio-economic status, those reporting smoking and drinking experience, and who do not participate in regular physical activity are more vulnerable to stress and depressive symptoms. CONCLUSION This is a noteworthy finding because it denotes that AD may lead to negative outcomes, like depressive symptoms or stress, which could be prevented if suspected early.

Abstract
According to previous studies, the increased risk of cutaneous infectious disorders in patients with atopic dermatitis (AD) is related to impaired epidermal function, abnormal systemic immune function, and lower antimicrobial peptides. In this study, we analyzed the association between AD and cutaneous infectious disorders in the real world using sequential pattern mining (SPM). We analyzed National Health Insurance data from 2010–2013 using SPM to identify comorbid cutaneous infectious diseases and the onset durations of comorbidities. Patients with AD were at greater risk for molluscum contagiosum (adjusted odds ratio (aOR), 5.273), impetigo (aOR, 2.852), chickenpox (aOR, 2.251), otitis media (aOR, 1.748), eczema herpeticum (aOR, 1.292), and viral warts (aOR, 1.105). In SPM analysis, comorbidity of 1.06% shown in molluscum contagiosum was the highest value, and the duration of 77.42 days documented for molluscum contagiosum was the shortest onset duration among all the association rules. This study suggests that AD is associated with an increased risk of cutaneous infectious disorders. In particular, care should be taken regarding its high relevance with impetigo, molluscum contagiosum, and otitis media, which may help in preventing AD from worsening through appropriately preventing and managing the condition.

Abstract
Background In 2015, the Korean Atopic Dermatitis Association (KADA) working group published consensus guidelines for treating atopic dermatitis (AD). Objective We aimed to provide updated consensus recommendations for systemic treatment of AD in South Korea based on recent evidence and experience. Methods We compiled a database of references from relevant systematic reviews and guidelines on the systemic management of AD. Evidence for each statement was graded and classified based on thestrength of the recommendation. Forty-two council members from the KADA participated in three rounds of voting to establish a consensus on expert recommendations. Results We do not recommend long-term treatment with systemic steroids forpatients with moderate-to-severe AD due to the risk of adverse effects. We recommend treatment with cyclosporine or dupilumab and selective treatment with methotrexate or azathioprine for patients with moderate-to-severe AD. We suggest treatment with antihistamines as an option for alleviating clinical symptoms of AD. We recommend selective treatment with narrowband ultraviolet B for patients with chronic moderate-to-severe AD. We do not recommend treatment with oral antibiotics for patients with moderate-to-severe AD but who have no signs of infection. We did not reach a consensus on recommendations for treatment with allergen-specific immunotherapy, probiotics, evening primrose oil, orvitamin D for patients with moderate-to-severe AD. We also recommend educational interventions and counselling for patients with AD and caregivers to improve the treatment success rate. Conclusion We look forward to implementing a new and updated consensus of systemic therapy in controlling patients with moderate-to-severe AD.

Abstract
The global epidemiology of atopic dermatitis (AD) in the current decade (2009-2019) has not been extensively reported. Epidemiological studies play an important role in presenting the risk factors of AD, as detailed prevalence and incidence data could demonstrate the burden of disease in the population of adults, adolescents, and children in different geographical regions. Thus, the primary objective of this review was to assess and summarize the epidemiological studies of the prevalence and incidence of AD in different age groups, focusing on data from studies published for 2009 to 2019. After a thorough literature search, six countries were identified from African, Asian, and European regions respectively, who published studies on AD. In contrast, only two studies were identified from Australia and New Zealand, three countries from North America and two from South America published AD studies, respectively. The highest prevalence of AD from included studies was noted among Swedish children with 34%, while the lowest prevalence was in Tunisian children with 0.65%; studies reporting incidence data were far less numerous. A common trend in the prevalence of AD was that children would have a higher prevalence as compared to adolescents and adults. The severity and morbidity of the disease showed variance with age, sex, socioeconomic characteristics, geographical location, and ethnicity. Environmental factors played an important role as causative agents in AD. The risk factors that were proven to cause and induce AD were skin barrier impairments due to FLG mutation, changes in the environment, and diet. FLG mutation may impair the skin barrier function by disruption of pH and hydration maintenance of the skin. Lastly, there were only a few studies on the incidence of AD in the 21st century. Therefore, epidemiological studies on childhood and adulthood AD in different continents are still needed, especially on the incidence of AD during adulthood.

Abstract
BACKGROUND Cytomegalovirus (CMV) can cause tissue-invasive diseases in various organs after primary infection or through reactivation of latent-to-lytic switch over a lifetime. The number of individuals who are at risk of CMV diseases, such as elderly or immunocompromised patients, is constantly increasing; however, recent epidemiological changes associated with CMV disease have not been fully evaluated. METHODS We used claims data of about 50 million individuals between 2010 and 2015 from the Korean Health Insurance Review and Assessment Service nationwide database. The code for CMV end-organ diseases in the 'Relieved Co-payment Policy' program matches the ICD-10 code of B25, except for congenital CMV infection and mononucleosis. A 628 cases of CMV and 3140 controls (without CMV disease), matched for age and sex, were selected from this dataset in order to evaluate the effect of adult CMV diseases on all-cause death. RESULTS The overall unadjusted incidence rate (IR) of CMV end-organ diseases was 0.52/100,000 individuals. The standardized IR, adjusted for age and sex, have continuously increased from 0.32/100,000 in 2010 to 0.75/100,000 in 2015. The overall unadjusted IR in adult population was highest in 70-79 years for six years (0.96/100,000). In the model adjusted for age, sex, immunocompromised status including solid-organ or hematopoietic stem cell transplant recipients, hematologic malignancies, and human immunodeficiency virus diseases, the hazard ratio of case group was 5.2 (95% confidence interval, 3.6-7.4) for all-cause mortality. CONCLUSION Nationwide data indicates that CMV end-organ disease has steadily increased in the past six years and is associated with higher mortality.

Abstract
Introduction As atopic dermatitis (AD) grows increasingly prevalent in Asian populations worldwide, understanding how environmental, genetic, and cultural factors uniquely influence AD in Asians is essential for informing disease management. Our objectives were to characterize the epidemiology of AD in East Asian populations with sensitivity to the changing demographics of AD in these populations and the effects of urbanization and immigration. Methods A systematic review was performed on epidemiologic studies of AD in East Asian populations over the past 10 years. Results There is a rising prevalence of both pediatric and adult AD in Asian populations worldwide, particularly in Asians living in urban areas. Studies suggest that the children of Asian immigrants may be at higher risk for developing AD, potentially resulting from epigenetic phenomena unique to immigrant populations. A number of genetic polymorphisms implicated in AD are shared by Asian populations around the world and appear to be rare among other ethnic populations. Conclusions As the prevalence of AD continues to increase in Asian populations, it is important to understand its distinct genetic and pathophysiologic profile in these populations, as well as characterize the cultural beliefs and practices surrounding its treatment. Future research should aim to capitalize on our growing understanding of pathophysiologic differences to inform the most promising treatments for AD in Asians. Additionally, the impact of immigration on AD suggests that further investigation of these trends may lead to a greater understanding of the epigenetics of AD.

Abstract
The relationship between oral health and atopic dermatitis (AD) remains unclear. Here we investigated the association between oral health status and AD using data from 634,299 subjects in the Korean Youth Risk Behavior Survey (KYRBS). Participants with oral symptoms were defined as those with any of following: sensitive teeth, toothache, bleeding gums or gum pain, and dry mouth. Current AD was determined by the question if participant had been diagnosed with AD from doctor within the past 12 months. We estimated the odds ratio (OR) for AD diagnosis according to the presence of oral symptoms. The OR for current AD, which is a dependent variable, was significantly increased in participants with oral symptoms, which are independent variables, in an adjusted model (OR, 1.27; 95% confidence interval [CI], 1.26–1.29; P < 0.001). In detailed analyses, all four oral symptoms were significantly associated with AD diagnosis: sensitive teeth (OR, 1.21; CI, 1.19–1.23; P < 0.001), bad breath (OR, 1.18; CI, 1.17–1.20; P < 0.001), toothache (OR, 1.18; CI, 1.16–1.20; P < 0.001), and bleeding gums (OR, 1.14; CI, 1.12–1.16; P < 0.001). In the presence of oral symptoms, the ORs for having two or more allergic diseases (AD, allergic rhinitis, and/or asthma) were higher than that of AD alone. In this study, oral symptoms appeared to be associated with AD in Korean adolescences.

Abstract
This study aimed to confirm the associations between stress and physical activity (PA) in Korean adolescents with atopic dermatitis (AD) based on data from the 2018-2019 Korea Youth Risk Behavior Web-Based Survey. The AD groups were divided into adolescents who were not diagnosed with AD, adolescents who were diagnosed with AD more than one year ago, and adolescents who were diagnosed with AD within one year. We defined the regular PA group and the non-PA group using the American College of Sports Medicine guidelines for children and adolescents: moderate to vigorous PA ≥5 times per week, including vigorous PA ≥3 days per week and muscle strengthening exercises ≥3 times per week. We performed logistic regression analysis to calculate the stress odds ratio (OR) and 95% confidence interval (CI) by group using model 1, adjusted for age, sex, and body mass index, and model 2, additionally adjusted for drinking, smoking, economic statuses, academic achievement, asthma, and rhinitis. In the group diagnosed with AD within one year, stress was 41% and 32% higher according to models 1 (1.41 (1.31-1.52)) and 2 (1.34 (1.20-1.50)), respectively. However, the stress OR was 30% lower in adolescents who completed regular PA than in the non-PA group (model 1: 0.71 (0.58-0.87); model 2: 0.68 (0.57-0.84)), even if diagnosed with AD within one year. In conclusion, the stress of adolescents with AD was significantly higher than that of adolescents without AD. The stress was significantly lower in the group with regular PA, and it was more robust in adolescents diagnosed with AD within one year.

Abstract
Background: It is widely acknowledged that food sensitization is related to atopic dermatitis in infants and young children. Objective: To investigate the association of aeroallergen sensitization with increased rates and severity of atopic dermatitis in school children. Methods: We enrolled 576 children (mean age, 9.4 ± 1.8 years) from six elementary schools. Atopic dermatitis was diagnosed by questionnaires, and severity was rated by physical examinations graded by using the Scoring Atopic Dermatitis (SCORAD) index. Skin-prick tests to 22 common allergens (6 aeroallergens and 16 food allergens) were conducted. Logistic and linear regression analyses were performed by using two models: model I adjusted for age, sex, and body mass index z score; and model II adjusted for all model I factors plus asthma and allergic rhinitis. Results: We diagnosed atopic dermatitis in 22.4% (n = 129) of the children, sensitization to foods in 48.3% (n = 278), and sensitization to aeroallergens in 11.3% (n = 65). A total of 26.2% of the children (n = 149) had mild and 6.5% had moderate-to-severe symptoms and signs of atopic dermatitis (n = 37). Atopic dermatitis was associated with sensitization to aeroallergens and eosinophilia (model I), but this risk was no longer significant after additional adjustment for current allergic status (model II). However, the relationship of the total SCORAD score with aeroallergen sensitization and eosinophilia was significant in model I and model II. Conclusion: The severity of atopic dermatitis correlated with the extent of allergic sensitization and eosinophilia. Analysis of our results suggests that more sensitization to dust mites and eosinophilia are related to increased rates and high severity scores of atopic dermatitis.

Abstract
BACKGROUND Atopic dermatitis is a chronic and relapsing inflammatory skin disease. Although mercury has been suggested as a risk factor, the underlying mechanism and the relationship between mercury and atopic dermatitis remains unclear. The objective of the present study was to investigate the relationship between mercury exposure and the presence of atopic dermatitis in early childhood. METHODS This study is part of the prospective Mothers and Children's Environmental Health cohort study. A total of 1,751 pregnant women were enrolled in Mothers and Children's Environmental Health. After delivery, children were followed up. Blood samples were collected and mothers were asked about the presence of atopic dermatitis in their children via a questionnaire at 6, 12, 24, 36, and 60 months of age. RESULTS After excluding participants who did not meet the inclusion criteria, a total of 1,061 mother-children pairs were included in the analysis. The geometric mean of mercury concentrations in cord blood was 5.1 µg/L. In adjusted models, cord blood mercury exposure (odds ratio [OR] = 1.1; 95% confidence interval [CI] = 1.0, 1.2 at 12-24 months) and postnatal mercury exposure (OR = 1.2; 95% CI = 1.0, 1.5 at 24-36 months, OR = 1.4; 95% CI = 1.1, 1.8 at 48-60 months) were associated with the presence of atopic dermatitis in children. CONCLUSIONS Postnatal mercury exposure at 24 months of age increases the risk of atopic dermatitis in children.

Abstract
BACKGROUND Allergic conditions and respiratory tract infections (RTIs) are common causes of morbidity and mortality in childhood. The relationship between vitamin D status in pregnancy (mothers), early life (infants) and health outcomes such as allergies and RTIs in infancy is unclear. To date, studies have shown conflicting results. OBJECTIVE This systematic review aims to gather and appraise existing evidence on the associations between serum vitamin D concentrations during pregnancy and at birth and the development of eczema, wheezing, and RTIs in infants. DATA SOURCES PubMed, MEDLINE, ProQuest, Scopus, CINAHL, Cochrane Library and Academic Search Premier databases were searched systematically using specified search terms and keywords. STUDY SELECTION Articles on the associations between serum vitamin D concentrations during pregnancy and at birth and eczema, wheezing, and RTIs among infants (1-year-old and younger) published up to 31 March 2019 were identified, screened and retrieved. RESULTS From the initial 2678 articles screened, ten met the inclusion criteria and were included in the final analysis. There were mixed and conflicting results with regards to the relationship between maternal and cord blood vitamin D concentrations and the three health outcomes-eczema, wheezing and RTIs-in infants. CONCLUSION Current findings revealed no robust and consistent associations between vitamin D status in early life and the risk of developing eczema, wheezing and RTIs in infants.

Abstract
Previous studies suggest an association between atopic dermatitis (AD) and exposure to microorganisms and antibiotics. However, these studies have limitations, and the sole influence on the development of AD was elusive. We performed a nationwide population-based case-control study in a Korean population to investigate the association between AD and early-life infection or antibiotic exposure. A total of 244 805 children with AD from the 2 283 601 children born between January 2010 and December 2014 and an equal number of sex- and age-matched healthy children were enrolled. A conditional logistic regression analysis showed that the episode of infection and antibiotic exposure were associated with an increased risk of AD (odds ratio [OR], 1.60; 95% confidence interval [CI], 1.58-1.63 for infection; and OR, 1.11; 95% CI, 1.09-1.13 for antibiotic exposure). A dose-dependent relationship was observed between risk for AD, the number of infection episodes and antibiotic cycles and the duration of antibiotic exposure. On further analysis using a conditional logistic model, the risk of AD was less when the antibiotics were used during the infection episode than that without the use of antibiotics, especially if the duration of the infection was short. Although our study could not consider the effect of cause or severity of infection, class of antibiotics and genetic or environmental factors of enrolled subjects, our results suggested that infection and antibiotic exposure were associated with an increased risk of AD. In addition, the results also implied that the use of antibiotics during an infection episode can decrease the risk of AD induced by the infection and that appropriate management of infections can minimize the risk of AD induced by infection or antibiotics.

Eye (Lond) 2020; 34:1909-1915. [PMID: 32080352 PMCID: PMC7608199 DOI: 10.1038/s41433-020-0816-1] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/17/2018] [Revised: 10/23/2019] [Accepted: 12/17/2019] [Indexed: 11/09/2022] Open
Abstract
PURPOSE Historically, atopic dermatitis (AD) is associated with an increased risk of rhegmatogenous retinal detachment (RRD). However, uncertainty remained regarding the effect of AD itself and comorbidities (e.g., allergic diseases, cataract surgery) on RRD occurrence in a large, population-based paediatric population. PATIENTS AND METHODS We analysed the 12-year National Health Insurance Service database (2002-2013) covering the entire Korean population to estimate the association between AD and RRD in people aged under 20 years. RESULTS We identified 3142 RRD patients, and matched 18,852 controls (six controls to each RRD patient); therefore, we included 21,994 peoples under aged 20 years in the analyses. AD was more prevalent in the RRD group (329 patients, 10.47%) than the control group (1043 patients, 5.53%; P < 0.001), and so were severe AD (153 patients [4.87%] and 223 patients [1.18%], respectively; P < 0.001). In conditional logistic regression analysis, AD was associated with RRD (OR, 1.61; 95% CI, 1.93-1.87) even after adjusting for allergic conditions, connective tissue disease, uveitis, and cataract surgery. In addition, severity of AD was associated with an increased risk of RRD (OR for non-severe AD and severe AD, 1.26 [95% CI, 1.05-1.51] and 2.88 [95% CI, 2.25-3.68]). CONCLUSION This study suggests that AD itself is a risk factor of RRD in children by showing the association between AD and RRD occurrence and the biologic gradient even after adjustment for known confounders including allergic conditions, uveitis, and cataract surgery.

Abstract
Wikstroemia indica (L.) C.A. Mey. is used in traditional Chinese medicine to treat inflammatory diseases such as arthritis and bronchitis. In this study, we aimed to investigate the effects of an ethanolic extract of W. indica on cutaneous inflammation in mice with 2,4-dinitrochlorobenzene (DNCB)-induced atopic dermatitis (AD). Dermal administration of W. indica ethanolic extract to DNCB-sensitized hairless mice with dermatitis, for two weeks, reduced erythema, scaling, and edema. Skin hydration was improved and transepidermal water loss was reduced at a W. indica concentration of 1%. Furthermore, W. indica also significantly reduced serum IgE and IL-4 concentrations in our mouse model. These results suggest that W. indica has potential as a topical treatment for AD and as an adjunctive agent to control AD.

Abstract
OBJECTIVE This study was aimed to evaluate epidemiological and clinical relationship between Mycoplasma pneumoniae (MP) infection and childhood recurrent wheezing episode (RWE). DESIGN Retrospective case note review. SETTING Paediatric department at a single Korean institution. PARTICIPANTS Consecutive admitted patients with MP pneumonia and RWE (0-15 years of age) between 2003 and 2014. METHODS The retrospective medical records of patients with (MP) pneumonia (n=793 for epidemiological analysis and n=501 for clinical analysis) and those with RWE (n=384) from 2003 to 2014 were analysed. Diagnosis of MP pneumonia was made based on two-times titration of IgM antibody during hospitalisation. An RWE patient was defined as one with expiratory wheezing with at least one or more wheezing episodes based on medical records. RESULTS During three MP pneumonia epidemics, there were no corresponding increases of patients with RWE in the epidemic years. In the 501 MP pneumonia patients, 52 (10.4%) had wheezing at presentation and 15 (3%) had RWE. The MP pneumonia patients with wheezing at presentation (n=52) were younger and were more likely to have an allergic disease history than those without wheezing (n=449). Among wheezing patients at presentation, 10 patients had previously RWE history. In a follow-up study, 13 patients (including 5 RWE) with initial wheezing and 25 patients (including 2 RWE) without wheezing had wheezy episodes after discharge. Among the total 501 patients, it was estimated that at least 31 MP pneumonia patients (6.2%) showed recurrent wheezing after initial MP infection. CONCLUSIONS A small part of children with MP pneumonia showed recurrent wheezing after MP pneumonia, and patients with RWE had a greater likelihood of experiencing wheezing when they had an initial MP infection. However, there were no increased admitted patients with RWE in MP pneumonia epidemic periods because of rarity of MP reinfection in children including patients with RWE or asthma.

Abstract
Patients with atopic dermatitis have high rates of skin surface colonization of Staphylococcus aureus. At the same time, S. aureus is the major causative organism in infective endocarditis, approximately accounting for 30%~50% cases of infective endocarditis. A 22-year-old male with severe atopic dermatitis presented with fever and myalgia. He was diagnosed with active infective endocarditis causing multiple cerebral infarction, splenic infarction, and septic shoulder requiring synovectomy. Blood culture proved methicillinsensitive Staphylococcus aureus bacteremia, and the culture from the skin revealed same bacteria. After treated with intravenous antibiotics for 6 weeks, patient was improved. Another 42-year-old female with severe atopic dermatitis who presented with fever and chilling was hospitalized due to acute infective endocarditis. She also had left flank pain and visual disturbance, due to splenic infarction and acute cerebral infarction, respectively. As blood culture revealed methicillin-sensitive Staphylococcus aureus bacteremia, she treated with intravenous antibiotics for 6 weeks. The route of entry of two patients was attributed to the patient eczematous scratching lesion of poorly controlled atopic dermatitis. Infective endocarditis can result in the context of acute deterioration of atopic dermatitis. Dermatologists need to pay attention to this risk and actively manage such conditions in order to decrease the risk of infective endocarditis arising from skin lesions in atopic patients. For these reasons, we herein report two cases of infective endocarditis in patients with atopic dermatitis.

Abstract
Background Recently, the number of domestic pets has increased. As a consequence, sensitization to animal allergens, such as cat or dog allergens, has become a problem. Objective We studied the annual trends of sensitization to cats or dogs, and the characteristics of the patients. Methods We retrospectively analyzed the medical records of 7,469 patients who visited a dermatology clinic and underwent an allergic profile test, from January 2011 to December 2015. Specific immunoglobulin E (IgE) levels to cat or dog antibody greater than 3.50 IU/ml were regarded as positive results. Results In all, 274 patients showed significant increase in levels of specific IgE antibody to dog, and 307 revealed increase in levels of of specific IgE antibody to cat. The prevalence of these specific IgEs increased from 2011 to 2015. Independent risks for sensitization to cat allergens were sensitization to dog, but not to house dust, Dermatophagoides pteronyssinus, and D. farinae. Independent risks for sensitization to dog allergens were sensitization to cat, but not to house dust, D. pteronyssinus, and D. farinae. Total IgE level was not related to specific IgE level against either cats or dogs. Conclusion In conclusion, the prevalence of sensitization to cat or dog has increased. Sensitization to cat or dog is related to each other, but is irrelevant to the total IgE level.

Abstract
PURPOSE The microbial environment is an important factor that contributes to the pathogenesis of atopic dermatitis (AD). Recently, it was revealed that not only bacteria itself but also extracellular vesicles (EVs) secreted from bacteria affect the allergic inflammation process. However, almost all research carried out so far was related to local microorganisms, not the systemic microbial distribution. We aimed to compare the bacterial EV composition between AD patients and healthy subjects and to experimentally find out the beneficial effect of some bacterial EV composition. METHODS Twenty-seven AD patients and 6 healthy control subjects were enrolled. After urine and serum were obtained, EVs were prepared from samples. Metagenomic analysis of 16s ribosomal DNA extracted from the EVs was performed, and bacteria showing the greatest difference between controls and patients were identified. In vitro and in vivo therapeutic effects of significant bacterial EV were evaluated with keratinocytes and with Staphylococcus aureus-induced mouse AD models, respectively. RESULTS The proportions of Lactococcus, Leuconostoc and Lactobacillus EVs were significantly higher and those of Alicyclobacillus and Propionibacterium were lower in the control group than in the AD patient group. Therefore, lactic acid bacteria were considered to be important ones that contribute to the difference between the patient and control groups. In vitro, interleukin (IL)-6 from keratinocytes and macrophages decreased and cell viability was restored with Lactobacillus plantarum-derived EV treatment prior to S. aureus EV treatment. In S. aureus-induced mouse AD models, L. plantarum-derived EV administration reduced epidermal thickening and the IL-4 level. CONCLUSIONS We suggested the protective role of lactic acid bacteria in AD based on metagenomic analysis. Experimental findings further suggest that L. plantarum-derived EV could help prevent skin inflammation.

Abstract
The effects of weather and air pollution on atopic dermatitis (AD) flares have not been well investigated. To investigate the effects of particulate matter (PM) on AD symptoms by weather type, a total of 125 young children (76 boys and 49 girls) under 6 years of age with AD living in Seoul, Korea, were enrolled as a panel and followed for 17 months between August 2013 and December 2014. AD symptoms were recorded on a daily basis, including itching, sleep disturbance, erythema, dry skin, oozing, and edema. Daily weather was classified into 7 categories according to spatial synoptic classification (SSC). Personal exposure to PM with an aerodynamic diameter less than 2.5 and 10 μm (PM2.5 and PM10, respectively) in each individual was estimated with time-weighted average concentrations considering outdoor and indoor levels of PMs and time to spend outdoors or indoors in a day. Generalized linear mixed models were used to analyze the effects of PM2.5 and PM10 on AD symptoms, controlling for ambient temperature, humidity, age, sex, SCORAD (SCORing of AD) at enrollment, fever, day of week, and topical corticosteroid use. A total of 20,168 person-days of symptom records were collected. The presence of AD symptoms was higher on dry polar (DP) days (45.4%, P < .0001) than on moist tropical (MT) days (37.7%, P < .0001). Overall, the risk of AD symptoms significantly increased with increased exposure to PM2.5 and PM10. Among the 7 weather types, the risks of AD symptoms caused by PM2.5 and PM10 exposure were significantly increased on dry moderate (DM) days, while not significant on the other weather types. In addition, lagged effect of PM2.5 up to 4 days was found on DM days. In conclusion, dry moderate weather type, particulate matters, and their modifying effects should be simultaneously considered for proper management of AD.

Abstract
The prevalence of allergic diseases has increased dramatically in recent decades, and are now considered major chronic diseases at the global level. The increasing burden of allergic diseases has led to numerous worldwide and local researchers to investigate the time trends in its prevalence and identify its driving factors. Environmental changes such as urbanization and industrialization have been suggested to explain the increasing prevalence, but recent reports from Western countries suggest that this prevalence has reached a plateau or even possibly, started to decrease. However, such environmental changes are still occurring in many Asia-Pacific countries, including Korea, and it is speculated that the peak in allergy epidemics has yet to come. The present systematic literature review aimed to explore the time trends in the prevalence of allergic diseases in Korea and to identify the unmet needs for facilitating further studies.

Abstract
This study aims to test the feasibility of a randomised clinical trial to evaluate how acupuncture affects atopic dermatitis (AD) symptoms and quality of life and to explore potential biomarkers that may be associated with AD. It is a sham-controlled trial in which 30 eligible patients will be randomly allocated in a 1 : 1 : 1 ratio to one of three groups: verum acupuncture (VA) group 1 (3 times weekly for 4 weeks); VA group 2 (twice weekly for 4 weeks); or sham acupuncture group (SA; twice weekly for 4 weeks). SA will consist of nonpenetrating acupuncture. Outcome measures will include the Visual Analogue Scale for itch, SCORing Atopic Dermatitis, and Eczema Area and Severity Index to evaluate AD symptoms improvement along with the Patient Oriented Eczema Measure and Dermatology Life Quality Index to assess quality of life. Measures will be collected at baseline, once weekly during the treatment period, and after a 4-week follow-up period. Blood collection will be at baseline and 4 and 8 weeks after treatment and compared with healthy controls. Illumina sequencing will be used to profile microRNA expression in each group to explore candidate microRNA biomarkers for specific effects of acupuncture in patients with AD. This trial is registered via US National Institutes of Health Clinical Trials registry (ClinicalTrials.gov) on 15 July 2016, identifier: NCT02844452.

Abstract
PURPOSE Atopic dermatitis (AD) is an inflammatory skin disease, significantly affecting the quality of life. Using AD as a model system, we tested a successive identification of AD-associated microbes, followed by a culture-independent serum detection of the identified microbe. METHODS A total of 43 genomic DNA preparations from washing fluid of the cubital fossa of 6 healthy controls, skin lesions of 27 AD patients, 10 of which later received treatment (post-treatment), were subjected to high-throughput pyrosequencing on a Roche 454 GS-FLX platform. RESULTS Microbial diversity was decreased in AD, and was restored following treatment. AD was characterized by the domination of Staphylococcus, Pseudomonas, and Streptococcus, whereas Alcaligenaceae (f), Sediminibacterium, and Lactococcus were characteristic of healthy skin. An enzyme-linked immunosorbent assay (ELISA) showed that serum could be used as a source for the detection of Staphylococcus aureus extracellular vesicles (EVs). S. aureus EV-specific immunoglobulin G (IgG) and immunoglobulin E (IgE) were quantified in the serum. CONCLUSIONS A metagenomic analysis together with a serum detection of pathogen-specific EVs provides a model for successive identification and diagnosis of pathogens of AD.

Analysis of Epidemiology and Risk Factors of Atopic Dermatitis in Korean Children and Adolescents from the 2010 Korean National Health and Nutrition Examination Survey. BIOMED RESEARCH INTERNATIONAL 2017; 2017:5142754. [PMID: 28904961 PMCID: PMC5585608 DOI: 10.1155/2017/5142754] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/15/2017] [Revised: 07/02/2017] [Accepted: 07/24/2017] [Indexed: 11/18/2022]
Abstract
BACKGROUND Atopic dermatitis (AD) is a common chronic inflammatory skin disease, but only few studies involved samples of children and adolescents that are representative of the entire Korean population. This study aimed to estimate the prevalence and risk factors of AD among children and adolescents in Korea by using nationally representative data. METHODS We used data from the fifth Korean National Health and Nutrition Examination Survey in 2010 and retrospectively evaluated 2,116 children and adolescents. Logistic regression analysis was performed to determine the relationship between AD and other variables, including IgE levels. RESULTS The prevalence rate of AD in children and adolescents was 15.0%. In the multivariate analysis of ages from 1 to 18 years, age (adjusted odds ratio [aOR], 0.96; p < 0.01) was related to AD. From age of 12 to 18 years, smoking (aOR, 8.99; p < 0.01) and elevated total IgE serum level (aOR, 5.31; p < 0.01) were related to AD. CONCLUSION Age, smoking, and elevated total IgE level were related to AD in the children and adolescents. Thus, an antismoking policy and public education are necessary for reducing the prevalence of allergic diseases. In addition, measurement of total IgE level and age may be helpful in the diagnosis of AD.

Abstract
INTRODUCTION Atopic dermatitis (AD) is one of the most common allergic diseases. Its prevalence has been increasing in recent decades. Socio-economic status is well-known risk factor of allergic diseases. OBJECTIVE This study was performed to investigate the relationship between socio-economic status and AD in Korean adults. METHODS Data were acquired from 47 351 men and women, ≥19 years of age who participated in the Korea National Health and Nutrition Examination Surveys (KNHANES) conducted from 2007 to 2014. The presence of AD was based on self-reported physician diagnosis of AD in the Health Interview Surveys. RESULTS The prevalence of AD was 3.1%, which decreased with increasing age. In univariate analysis, adults with AD were prone to be female, younger, never-married, well educated, lower household members, and urban dwelling (all P < 0.01). Monthly family income and smoking status were not associated with the presence of AD. The prevalence of hypertension, diabetes mellitus and asthma was higher in AD subjects (all P < 0.01), while obesity was not associated with adult AD. After adjusting for confounders, logistic regression analysis showed female sex (adjusted odds ratio [aOR]: 1.483, 95% CI: 1.268-1.734), age (P < 0.01), marital status (Single: aOR: 1.307, 95% CI: 1.012-1.690; Never-married: aOR: 1.938, 95% CI: 1.513-2.482), urban residence (aOR: 1.281, 95% CI: 1.045-1.569) and asthma (aOR: 1.788, 95% CI: 1.416-2.258) were associated with higher prevalence of AD (all P < 0.01). CONCLUSION Female sex, age, marital status, urban residence, and the presence of asthma are important risk factors of the prevalence of AD in Korean adults.

Abstract
PURPOSE Atopic dermatitis (AD) is a chronic eczematous dermatitis that has a high prevalence and diverse clinical features. Although several hypotheses about its multifactorial pathogenesis have been suggested, the cause is not yet fully understood. A better understanding of the clinical features may helpful inelucidating the pathogenesis of AD. METHODS This retrospective study analyzed the questionnaires, medical charts, and laboratory examination results of 5,000 patients diagnosed with AD at a single tertiary hospital in Korea. RESULTS The demographics, allergic comorbidities, family history, severity, and treatment experiences of the patients were analyzed. Most of the patients were adults, 76.3% of whom were classified as havingan extrinsic type of AD. The mean eczema area and severity index (EASI) score was found to be 13.68, and adult patients were found to have higher severity than the other age groups. The anatomical involvements were different among the age groups, with more involvements of the head and neck in adults. The patients reported seasonal changes and stress as the factors that aggravated their symptoms the most. Topical steroids and oral cyclosporine were the most used medications at our clinic, whereas 10.1% of the patients underwent allergen-specific immunotherapy. CONCLUSIONS This analysis of 5,000 patients would lead to a better understanding of various subtypes and diverse clinical features of AD in Koreans. Distinct characteristics were observed among different age groups; thus, treatment strategies may need to be differentiated accordingly.
