A LONG PROSPECTIVE OBSERVATIONAL STUDY ON PREVALENCE OF ATOPIC DERMATITIS IN EARLY CHILDHOOD TO ADOLESCENCE

There are few prospective observational studies on the prevalence of atopic dermatitis (AD) in children. We aimed to prospectively investigate the dynamics of change in the prevalence of AD from early childhood to adolescence. We conducted a survey with a modified questionnaire to diagnose AD based on The International Study of Asthma and Allergies in Childhood questionnaire with 1230 13-year-old children who were born in the Minami ward, Yokohama City between May 2004 and June 2005 and had undergone physical examinations by dermatologists at 3 years of age. Among the 422 children who answered the questionnaire, 210 had undergone periodic physical examinations by dermatologists from 4 months to 3 years of age (Cohort 1), whereas 212 had undergone physical examinations only at 3 years of age (Cohort 2). The prevalence of AD was 16.9% in 422 children at 13 years of age, with 22.9%, 16.6%, 20.0% and 18.3% prevalence at 4 months, 18 months, 3 years and 13 years of age, respectively, in children who were followed up long-term. The frequency of AD occurrence per year decreased after the age of 3 years; a history of AD at this age was significantly related to AD at 13 years of age (Fisher's exact test, p<0.001). In conclusion, it was suggested that AD in 3-year-old children is one of the risk factors for the development of AD in 13-year-old children.

Postnatal Health in Children Born to Women After Bariatric Surgery.

The aim of this study is to evaluate short- and long-term consequences in children born to women after different bariatric surgery (BS) procedures. A questionnaire survey was given to the mothers referred from 1994 to 2019 to our center for pregnancy and delivery management after BS procedures: (a) malabsorptive surgery, (b) restrictive procedures, and (c) combined restrictive-malabsorptive procedures. Data from 74 children born after BS, aged 0month to 12years, were analyzed. The prevalence of children with underweight was 5.4%, normal weight 59.5%, overweight 16.2%, and obesity 18.9%. The prevalence of obesity was higher in children pre-school aged than that in school-aged ones. Neurodevelopmental disorders were more frequent if maternal BMI before bariatric surgery was ≥ 41kg/m2 (p = 0.008), as well as if the pregnancy occurred less than 18months after BS (p = 0.028). In school-aged children conceived within 18months after BS, the highest risk of neurodevelopmental disorders (p = 0.028) and overweight (p = 0.018) was observed. The prevalence of neurodevelopmental disorders was much higher for small for gestational age babies (p = 0.048). Children born after biliopancreatic diversion (BPD) showed less maternal breastfeeding, shorter breastfeeding duration, more overweight, and more occurrence of atopic dermatitis in comparison with children born after other bariatric procedures. Postnatal health in children born to women after BS was impaired by long-term consequences and by other diseases later in life. Children born after BPD were particularly at higher risk for short and long term consequences when compared to children born after other BS procedures.

Antibiotics administration during last trimester of pregnancy is associated with atopic dermatitis - a cross-sectional study.

Studies regarding antibiotics administration during pregnancy and atopic dermatitis (AD) in children are only few. In this context, the objective of our study was to investigate the potential association between the timing of intrauterine exposure to antibiotics or prenatal antibiotic administration in general and AD occurrence in children. This was a cross-sectional study in 1046 subjects. The exposure to antibiotics during pregnancy was initially evaluated using simple logistic regressions. Then, each period of antibiotics administration was adjusted with the other periods of antibiotics exposure (model 1) and with the other variables associated with AD in our database (model 2). In simple logistic regression analysis, the administration of antibiotics during pregnancy, as a whole period, presented a trend of association with AD (OR = 1.28, %CI: 0.99 - 1.65). When we analyzed antibiotic administration during each trimester of pregnancy, only antibiotherapy during the 3rd trimester was associated with AD (OR = 2.94, %CI: 1.21 - 7.12). After adjusting with all the other important risk factors associated with AD in the database, antibiotics administration during the 3rd trimester of pregnancy was still independently associated with AD (OR=2.64, %CI: 1.01 - 6.91). Antibiotic administration during the 3rd trimester of pregnancy was independently associated with AD in children.

The role of psychological stress in atopic dermatitis through an increase of IL-31

AbstractIntroduction: Atopic dermatitis occurs due to multifactorial interactions such as genetic, environmental, impaired skin barrier function, immunological factors, infection and post-psychological stress. Th1 cells and some proinflammatory cytokines such as IL-6, IL-10 and others play a role in the pathogenesis of atopic dermatitis, also IL-31. IL-31, including cytokines of the IL-6 family expressed mainly on CD4 T cells. Many researchers also associate stress with the occurrence of atopic dermatitis, stress will trigger the release of these cytokines from immune cells (e.g. IL-6, TNF α). The aim of the study is determine correlation between stress and increase in IL-31 level in person with atopic dermatitisMethod: We designed a case-control study including 58 patient, range from 14-65 years old. Diagnosis of atopic dermatitis is established based on Hanifin and Rajka criteria, and the severity based on SCORAD. Venous blood was collected for IL-31 examination, stress index was measured by interview according to the Holmes-Rahe stress scale test method.Result: In this study, the stress index in atopic dermatitis was 102.26 + 11.71, and in control 61.35 + 19.87 there was a significant difference with p &lt;0.005. IL-31 levels in atopic dermatitis were 274.44 + 95.35, higher than controls 129.44 + 85.45, significantly with p&lt;0.005. The results of linear regression between stress index and severity of dermatitis (SCORAD), appeared to have a moderate positive correlation with r = 0.04. OR 4.56 (95% CI 2.78-11.56).Conclusions: From this study it can be concluded that stress increases IL-31 levels and positively correlates with the severity of atopic dermatitis.

Exposure to diisononyl phthalate promotes atopic march by activating of NF-κB and p38 MAPK

What factors and underlying mechanisms influence the occurrence of the atopic march remain unclear. Recent studies suggest that exposure to diisononyl phthalate (DINP) might be associated with the occurrence of atopic dermatitis (AD) and asthma. However, little is known about the role of DINP exposure in the atopic march. In this study, we investigated the effect of DINP exposure on the progression from AD to asthma, and explored the potential mechanisms. We built an atopic march mouse model from AD to asthma, by exposure to DINP and sensitization with OVA. Pyrrolidine dithiocarbamate and SB203580 were used to block NF-κB and p38 MAPK respectively, to explore the possible molecular mechanisms. The data showed that DINP aggravated airway remodeling and airway hyperresponsiveness (AhR) in the progression from AD to asthma, induced a sharp increase in IL-33, IgE, Th2 and Th17 cytokines, and resulted in an increase in the expression of thymic stromal lymphopoietin (TSLP) and in the number of inflammatory cells. Blocking NF-κB inhibited AD-like lesions, and the production of IL-33 and TSLP in the progression of AD, while alleviating airway remodeling, AhR, and the expression of Th2 and Th17 cytokines in both the progression of AD and the asthmatic phenotype. Blocking p38 MAPK in the progression of asthma, inhibited airway remodeling, AhR, and the expression of Th2 and Th17 cytokines. The results demonstrated that exposure to DINP enhanced the immune response to memory CD4+ T helper cells through the NF-κB and p38 MAPK signaling pathways, leading to an aggravation of the atopic march.

The Association with rhegmatogenous retinal detachment and paediatric atopic dermatitis: a 12-year Nationwide Cohort Study.

PurposeHistorically, 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 methodsWe 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.ResultsWe 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]).ConclusionThis 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.

The role of antioxidants and 25-hydroxyvitamin D during pregnancy in the development of allergic diseases in early school-age children ‐ Polish Mother and Child Cohort Study

Purpose: Based on the available data, alterations of the antioxidant defense as well as the vitamin status in mothers may affect the prenatal process of lung and immune system development as a pathophysiological background of increased prevalence of allergic diseases. The primary aim of the current study was to assess the associations among cord blood concentrations of zinc (Zn); copper (Cu); selenium (Se); β-carotene; and vitamin A, E, and D, and the occurrence of atopic dermatitis, food allergy, allergic rhinitis, and asthma in early school-age children. Methods: We evaluated 211 children, 7-9 years old, from the Polish Mother and Child Cohort Study. the women were interviewed during pregnancy to collect demographic and socioeconomic data, and the medical and reproductive history. At delivery, umbilical cord blood plasma was sampled. Seven to nine years after the birth, the child's exposure and health status (including skin-prick test and spirometry for allergy assessment and urine sample for cotinine level) were examined. In the analyses, a multivariable model was applied. Results: Statistically significant relationships were found among Zn; Cu; Se; and vitamin A, E, and D concentrations in cord blood; and the prevalence of food allergy, allergic rhinitis, atopic dermatitis, and asthma in children ages 7-9 years after adjustment for several confounders. Conclusion: We showed an imbalance in the antioxidant defense system in cord blood, which may lead to the occurrence of allergic diseases later in life. The maternal diet may have substantial potential to modify immune tolerance and, consequently, the development of allergic disease in the offspring.Clinical trial NCT01861548, <ext-link xmlns:xlink="http://www.w3.org/1999/xlink" ext-link-type="uri" xlink:href="http://www.clinicaltrials.gov">www.clinicaltrials.gov</ext-link>.

Influence of silk clothing therapy in patients with atopic dermatitis.

The existence of red, inflammatory, and chronic itchy condition in the skin is commonly speculated as the presence of Atopic Dermatitis (AD) in patients. The use of silk clothing as a non-pharmacological approach in the management of AD has been noticed as an effective alternative therapy; however, the evidence based on its usage is poorly served. Hence, we aim to evaluate the effectiveness of using pure silk clothing in the therapy of AD patients. The clinical trial was performed by recruiting 30 patients with AD for up to 8 weeks of observation. They were instructed to wear pure silk clothing for the whole day without any additional medication and were investigated using the AD-related questionnaires. The findings revealed a significant decrease of AD occurrence along with a great improvement of patient’s quality of life at each time point. Our investigation demonstrated that this treatment promotes good skin appearance, comfort, and remarkable improvement in the quality of life. This promising preliminary outcome warrants a further study; hence, it can be a potential non-pharmacological treatment choice for controlling the severity of AD.

Skin Care and Synbiotics for Prevention of Atopic Dermatitis or Food Allergy in Newborn Infants: A 2 × 2 Factorial, Randomized, Non-Treatment Controlled Trial

Background: Atopic dermatitis (AD) and food allergy (FA) are common childhood diseases, which may either be interrelated or be the result of skin barrier disruption and gut mucosal dysbiosis. Although some evidence suggests the efficacy of emollients and synbiotics, there is no conclusive evidence on the use of these interventions alone or in combination. Objectives: This study is aimed at identifying the efficacy of emollients and synbiotics in preventing AD and FA in children during the first year of life. Methods: The babies of mothers recruited prenatally received either an emollient, synbiotic, both or neither. The intervention was carried out from birth up to 6 months of age. The age of occurrence of AD and FA were reported in multiple questionnaires at 1, 6, and 9 months and at 1 year of age. AD was diagnosed by a pediatrician at 9 months of age. Results: A ­total of 459 babies qualified for the outcome assessment at 1 year of age. Neither the emollient nor the synbiotic showed any effect on reducing the development of AD and FA at 1 year of age. Conclusions: This study did not provide any evidence to show that emollients and synbiotics, alone or in combination are sufficient to prevent the occurrence of AD or FA in children up to 1 year of age.

Alterations in the skin microbiome are associated with disease severity and treatment in the perioral zone of the skin of infants with atopic dermatitis.

Atopic dermatitis (AD), a chronic relapsing inflammatory pruritic skin disorder with a unique pathophysiology, has a high incidence in the perioral zone among infants. This study aimed to analyze the association of skin microfloral dynamics with disease severity and treatment of AD in 0-1-year-old infants. Based on the eczema area and severity index, subjects were divided into five groups, i.e., mild, moderate, severe, and severe post-treatment, with a healthy control group, and bacterial density at the perioral lesion, disease severity, and treatment were assessed in 0-1-year-old infants with AD. The perioral lesions were colonized predominantly by Firmicutes, followed in abundance by Proteobacteria, Actinobacteria, and Bacteroidetes. In the phylum Firmicutes, Streptococcus was the most predominant genus. In AD infants, the abundance of Bacteroidetes and Fusobacterium decreased significantly with an increase in disease severity (p < 0.01). The abundance of 6 genera, including Prevotella, decreased significantly with an increase in disease severity (p < 0.05). The abundance of Prevotella melaninogenica decreased gradually with an increase in disease severity and increased after treatment; this trend was reversed for Corynebacterium simulans. A reduction in the abundance of Staphylococcus and an increase in that of skin microflora including Prevotella spp., Staphylococcus epidermidis, and Erwinia dispersa were associated with treatment and clinical improvement. Skin bacterial composition varies with AD severity, and Corynebacterium simulans and Prevotella melaninogenica are positively and negatively correlated with AD severity, respectively. This study provides a theoretical basis to identify potential biomarkers AD occurrence and pathogenesis.

Prenatal perfluorooctanoic acid exposure is associated with early onset atopic dermatitis in 5-year-old children

Atopic dermatitis (AD) is the most common childhood skin disease and the first step of atopic march. Perfluoroalkyl substance (PFAS) exposure is associated with atopic diseases, including AD. However, whether PFAS exposure is related to earlier AD onset remains unclear. We aimed to investigate the association between prenatal PFAS exposure and earlier onset of AD in children in a 5-year follow-up study. From 2001 to 2005, 1264 mother-infant pairs were recruited from eight Taiwanese maternity hospitals. PFAS levels were analyzed from cord blood. Information on children's health status, including AD occurrence, was obtained via phone interviews at multiple time points. Perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS) concentrations were measured by ultra-high performance liquid chromatography/tandem mass spectrometry. Cox proportional hazards models assessed associations between prenatal PFAS exposure and early onset AD. Overall, 863 mother–infant pairs with complete measurements were recruited. The prevalence of physician-diagnosed AD before 5 years of age was 7.1%. PFOA and PFOS concentrations were grouped based on whether they were above the 75th percentile. PFOA exposure was positively associated with earlier onset of AD (Kaplan-Meier estimate, p = 0.014). In the Cox model, after adjusting for sex, family income, parental atopy, breast feeding, and maternal age at childbirth, significance was observed in children above the upper quartile (≥75th) of the PFOA group (hazard ratio: 1.89; 95% confidence interval, 1.10–3.16). Our findings suggested that children with higher prenatal PFOA exposure have a higher risk of earlier AD development. Minimizing early life PFAS exposure may help inhibit AD development.

Prenatal perfluorooctanoic acid exposure and glutathione s-transferase T1/M1 genotypes and their association with atopic dermatitis at 2 years of age.

BackgroundPerfluoroalkyl substance (PFAS) exposure was found associated with atopic diseases. Atopic dermatitis (AD) is a childhood skin disorder. However, the effect of interaction between PFASs and glutathione S-transferase (GST) T1/M1 genotype on AD remains unclear.ObjectiveTo investigate the association between gene-environmental interaction and childhood AD using a birth cohort study.MethodsFrom 2001 to 2005, 1,264 mother–newborn pairs were recruited from eight Taiwanese maternity hospitals. PFAS levels and Genotypes were analysed from cord blood. Information on children’s health status including AD occurrence was obtained via phone interviews at 6 months and 2 years. Cord plasma concentrations of nine PFASs were measured via ultra-high performance liquid chromatography/tandem mass spectrometry. GSTT1/M1 was genotyped (null/present) via polymerase chain reaction. Environment-gene interaction effects on AD were assessed using multiple logistic regression analysis.ResultsOverall, 839 mother–newborn pairs completed all measurements. The prevalence of ever having physician-diagnosed AD by 2 years of age was 5.4%. Among PFASs, perfluorooctanoic acid (PFOA) was positively associated with AD adjusted for potential confounders. After grouping PFOA levels into three groups: undetected, below and above the median in those with detected, children in above the median group who had the GSTT1-null, or GSTM1-null genotype exhibited a higher odds ratio for AD (OR [95%CI] = 3.45 [1.26–9.99] and 2.92 [1.12–7.91], respectively) as compared to the undetected group.ConclusionsOur data demonstrated that in-utero PFOA exposure with GSTT1/M1 null genotype were associated with AD. Minimizing early-life PFAS exposure may help against AD development, especially in genetically susceptible individuals.

Simultaneous detection of barrier- and immune-related gene variations in patients with atopic dermatitis by reverse blot hybridization assay.

Hereditary factors are involved in the pathogenesis of atopic dermatitis (AD). However, AD-related gene variations are significantly different across ethnicities. To identify mutations and single-nucleotide polymorphisms (SNPs) in barrier- or immune-related genes from Korean patients with AD and compare the variations with those observed in nonatopic healthy controls (HCs), and to use novel reverse blot hybridization assay (REBA) for AD-related gene variants. We carried out REBA to simultaneously detect variations in genes related to barrier or immune function, namely, FLG, SPINK5, KLK7, DEFB1, TNFα, KDR, FCER1A, IL4, IL5,IL5RA, IL9, IL10, IL12, IL12R, IL13 and IL18, from Korean patients with AD, and compared the variation to that in nonatopic healthy controls. The homozygous mutants of KLK7 and SPINK5-2475, and the heterozygous mutants of FLG 3321delA, SPINK5-1156, DEFB1, KDR, IL5RA, IL9 and IL12RB1 were significantly more frequent in AD. It has been predicted that the larger the number of gene variants, the higher the odds ratio of AD prevalence; however, we did not find any significant correlation between the number of gene variants and AD severity. Using REBA, we identified more genetic variants that can predict AD occurrence. We also verified that REBA can be used to easily and accurately detect multiple AD-related gene variants simultaneously. In addition, we identified a correlation between KLK7 mutation and AD in Koreans, which is the first such report, to our knowledge.

Atopic dermatitis in children aged 1 - 7 years in Shenzhen city: an epidemiological study

Objective To investigate the prevalence of and influencing factors for atopic dermatitis (AD) in children aged 1 - 7 years in Shenzhen city, and to analyze difference in diagnostic results between two diagnostic criteria. Methods From December 1st 2013 to March 1st 2014, a questionnaire survey and physical examination were conducted to investigate the prevalence of AD in children aged 1 - 7 years in Shenzhen city. Results A total of 1 504 children were enrolled into this study, including 716 males and 788 females. Based on the clinical diagnosis by experienced dermatologists, the prevalence of AD was 11.84% (178/1 504) in total, 11.73% (84/716) and 11.93% (94/788) in males and females, respectively, and there was no significant difference in the prevalence of AD between males and females (χ2 = 0.01, P > 0.05) . Based on the Williams′ diagnostic criteria, the prevalence of AD was 3.92% (59/1 504) in total, and 4.05% (29/716) and 3.81% (30/788) in males and females, respectively. Premature birth was a risk factor for the occurrence of AD (χ2 = 5.43, P < 0.05) . Conclusions The prevalence of AD is evidently increased among children aged 1 - 7 years in Shenzhen city, and premature birth is a risk factor for AD. Missed diagnosis will be reduced based on clinical diagnosis by experienced dermatologists. Key words: Dermatitis, atopic; Child; Prevalence; Population characteristics

Maternal Stress During Pregnancy and Allergic Diseases in Children During the First Year of Life.

Many recent studies indicate that prenatal maternal distress increases the risk of allergic diseases in children. The mechanisms that favor it are still unclear. We aimed to assess the association between exposure to different kinds of prenatal stress and the occurrence of atopic dermatitis, food allergy, wheezing, and recurrent respiratory tract infections in children. The study population consisted of 370 mother-child pairs from a Polish Mother and Child Cohort (REPRO_PL). The analysis was restricted to the women who worked at least one month during the pregnancy period. Maternal psychological stress during pregnancy was assessed based on the Subjective Work Characteristics Questionnaire, the Perceived Stress Scale, and the Social Readjustment Rating Scale. The presence of atopic dermatitis, food allergy, wheezing, and recurrent respiratory tract infections in children was evaluated by doctors at 12 months of age. In a univariate model, we showed significant association between maternal life stress (according to the Perceived Stress Scale) and stressful life events (according to the Social Readjustment Rating Scale) and infant wheezing (at least 1 episode of wheezing during the first year of life). A multivariate model of logistic regression analysis revealed that maternal stress during pregnancy, described by the Social Readjustment Rating Scale, increased the risk of wheezing in children (OR 1.09, 95% CI 1.01-1.02) independently from other predictors of wheezing previously determined in this cohort, such as the number of infections and maternal smoking. We observed also significant positive association between maternal life stress during pregnancy measured by the Perceived Stress Scale and the risk of recurrent respiratory tract infections in the first year of life, however it was not significant after adjustment for confounding variables. Maternal stress during pregnancy increases the risk of childhood wheezing. The effects of stress during pregnancy on the onset of allergic diseases in children should be developed and translated into early prevention strategies.

Probiotics for the treatment of atopic dermatitis

Atopic dermatitis (AD) is a chronic recurrent skin disease, and mostly occurs during infancy and childhood. Epidemiologic studies have found that the prevalence of AD has been greatly increasing in many countries in the past 30 years. The occurrence of AD is mainly related to skin barrier impairment, abnormality of immune function and changes of bacterial flora. Probiotics are live microorganisms, and appropriate probiotic supplementation is beneficial to the host. As a kind of immune modulator, their safety has been proved. In clinic, probiotics can be used for the treatment of inflammatory skin diseases, such as AD. Key words: Dermatitis, atopic; Microbial consortia; Immunomodulation; Prebiotics; Therapeutic uses

Weissella cibaria WIKIM28 ameliorates atopic dermatitis-like skin lesions by inducing tolerogenic dendritic cells and regulatory T cells in BALB/c mice

The occurrence of atopic dermatitis (AD), a chronic inflammatory skin disease, has been increasing steadily in children and adults in recent decades. In this study, we evaluated the ability of the lactic acid bacterium Weissella cibaria WIKIM28 isolated from gatkimchi, a Korean fermented vegetable preparation made from mustard leaves, to suppress the development of AD induced by 2,4-dinitrochlorobenzene in a murine model. Oral administration of W. cibaria WIKIM28 reduced AD-like skin lesions, epidermal thickening, and serum immunoglobulin E levels. Furthermore, the production of type 2 helper T (Th2) cytokines such as interleukin (IL)-4, IL-5, and IL-13 decreased in peripheral lymph node cells. Moreover, the intake of W. cibaria WIKIM28 increased the proportion of CD4+CD25+Foxp3+ regulatory T (Treg) cells in mesenteric lymph nodes (MLNs) and IL-10 levels in polyclonally stimulated MLN cells. In conclusion, the oral administration of W. cibaria WIKIM28 isolated from gatkimchi ameliorated AD-like symptoms by suppressing allergic Th2 responses and inducing Treg responses. These results suggest that W. cibaria WIKIM28 may be applicable as a probiotic for the prevention and amelioration of AD.
