The association between lung cancer and eczema remains controversial. Previous studies have yielded conflicting results. This retrospective population-based cohort study is aimed at clarifying the risk of lung cancer associated with eczema. By using the Taiwan National Health Insurance Research Database, we identified 43,719 patients who had been newly diagnosed with eczema in the years 2000 to 2010. The comparison cohort included 87,438 randomly selected, age-matched patients without eczema. The cases of these two cohorts were followed until 2011. The Cox proportional hazard regression model was used to calculate the risk of lung cancer in eczema patients. The database did not contain any information regarding smoking, alcohol consumption, socioeconomic status, or family history. After adjusting for age and comorbidity, the population with eczema had a 2.80-fold greater risk of developing lung cancer compared with the population in the comparison cohort (adjusted hazard ratio 2.80, 95 % confidence interval 2.59-3.03). Eczema patients with comorbid diseases including asthma, chronic obstructive -pulmonary disease, alcoholic liver damage, or diabetes were at a higher risk of lung cancer compared with the non-eczema patients without comorbidity. Eczema is associated with a greater risk for the development of lung cancer. Further studies with more comprehensive information on potential confounders are warranted. © 2016 Deutsche Dermatologische Gesellschaft (DDG). Published by John Wiley & Sons Ltd.

Objective: Patients with severe chronic hand eczema often have persistent symptoms that interfere with daily activities, social functioning, and employment. Many patients are refractory to topical corticosteroids. This survey-based study was performed to characterize treatment experiences, impact on productivity, and quality of life of patients with severe chronic hand eczema; understand dermatologists’ severe chronic hand eczema treatment patterns. Design: A web-based survey in the United States queried pre-identified patients with severe chronic hand eczema regarding symptoms, treatment history, quality of life, work productivity, treatment satisfaction, and healthcare utilization. In a separate survey, dermatologists were asked about treatment patterns and satisfaction with currently available therapies. Results: The most commonly reported symptoms currently experienced by patients (n=163) were dryness/flaking (81%), itchiness (75%), and cracking/tearing of the skin (71%). Over the last three months, 84 percent of patients with severe chronic hand eczema self-reported using topical steroids, and 30 percent used systemic corticosteroids or retinoids. Approximately 30 percent reported impairment while working and productivity loss. Patient quality of life was negatively impacted. Dermatologists (n=125) reported most often treating severe chronic hand eczema with topical corticosteroids (99%), followed by topical immunomodulators (71%) and systemic treatments (70%). Only two percent were very satisfied with currently available products. Conclusion: Patients with severe chronic hand eczema experience symptoms that negatively impact work productivity and quality of life. Few dermatologists are very satisfied with currently available severe chronic hand eczema treatment options. PMID:26705436

The aim of the study was to assess the susceptibility of clinically normal skin to a standard irritant trauma under varying physiological and patophysiological conditions. Evaluation of skin responses to patch tests with sodium lauryl sulphate (SLS) was used for assessment of skin susceptibility. The following noninvasive measuring methods were used for evaluation of the skin before and after exposure to irritants: measurement of transepidermal water loss by an evaporimeter, measurement of electrical conductance by a hydrometer, measurement of skin blood flow by laser Doppler flowmetry, measurement of skin colour by a colorimeter and measurement of skin thickness by ultrasound A-scan. The studies were carried out on healthy volunteers and patients with eczema. In the first studies the standard irritant patch test for assessment of skin susceptibility was characterized and validated. SLS was chosen among other irritants because of its ability to penetrate and impair the skin barrier. The implications of use of different qualities of SLS was investigated. The applied noninvasive measuring methods were evaluated, and for quantification of SLS-induced skin damage measurement of TEWL was found to be the most sensitive method. Application of the standard test on clinically normal skin under varying physiological and patophysiological conditions lead to the following main results: Seasonal variation in skin susceptibility to SLS was found, with increased susceptibility in winter, when the hydration state of the stratum corneum was also found to be decreased. A variation in skin reactivity to SLS during the menstrual cycle was demonstrated, with an increased skin response at day 1 as compared to days 9-11 in the menstrual cycle. The presence of active eczema distant from the test site increased skin susceptibility to SLS, indicating a generalized hyperreactivity of the skin. Taking these sources of variation into account healthy volunteers and patients with hand eczema and atopic dermatits were studied and compared. In healthy volunteers increased baseline TEWL and increased light reflection from the skin, interpreted as "fair" skin, was found to be associated with increased susceptibility to SLS. Hand eczema patients were found to have fairer and thinner skin than matched controls. Increased susceptibility to SLS was found only in patients with acute eczema. Patients with atopic dermatitis had increased baseline TEWL as well as increased skin susceptibility as compared to controls. Skin susceptibility is thus influenced by individual- as well as environment-related factors. Knowledge of determinants of skin susceptibility may be useful for the identification of high-risk subjects for development of irritant contact dermatitis, and may help to prevent the formation of the disease.

Hand eczema is a common and persistent disease with a relapsing course. Clinical data suggest that once daily treatment with corticosteroids is just as effective as twice daily treatment. The aim of this study was to compare once and twice daily applications of a strong corticosteroid cream in addition to maintenance therapy with a moisturizer in patients with a recent relapse of hand eczema. The study was a parallel, double-blind, randomized, clinical trial on 44 patients. Twice daily application of a strong corticosteroid cream (betamethasone valerate 0.1%) was compared with once daily application, where a urea-containing moisturizer was substituted for the corticosteroid cream in the morning. The investigator scored the presence of eczema and the patients judged the health-related quality of life (HRQoL) using the Dermatology Life Quality Index (DLQI), which measures how much the patient's skin problem has affected his/her life over the past week. The patients also judged the severity of their eczema daily on a visual analogue scale. Both groups improved in terms of eczema and DLQI. However, the clinical scoring demonstrated that once daily application of corticosteroid was superior to twice daily application in diminishing eczema, especially in the group of patients with lower eczema scores at inclusion. Twice daily use of corticosteroids was not superior to once daily use in treating eczema. On the contrary, the clinical assessment showed a larger benefit from once daily treatment compared with twice daily, especially in the group of patients with a moderate eczema at inclusion. © 2011 The Authors.

Tongue observation often depends on subjective judgment, it is necessary to establish an objective and quantifiable standard for tongue observation. To discuss the features of tongue manifestation of patients who suffered from eczema with different types and to reveal the clinical significance of the tongue images. Two hundred patients with eczema were recruited and divided into three groups according to the diagnostic criteria. Acute group had 47 patients, subacute group had 82 patients, and chronic group had 71 patients. The computerized tongue image digital analysis device was used to detect tongue parameters. The L*a*b* color model was applied to classify tongue parameters quantitatively. For parameters such as tongue color, tongue shape, color of tongue coating, and thickness or thinness of tongue coating, there was a significant difference among acute group, subacute group and chronic group (P< 0.05). For Lab values of both tongue and tongue coating, there was statistical significance among the above types of eczema (P< 0.05). Tongue images can reflect some features of eczema, and different types of eczema may be related to the changes of tongue images. The computerized tongue image digital analysis device can reflect the tongue characteristics of patients with eczema objectively.

Hand eczema is the most frequently recognized occupational disease in Denmark with an incidence of approximately 0.32 per 1000 person-years. Consequences of hand eczema include chronic severe eczema, prolonged sick leave, unemployment, and impaired quality of life. New preventive strategies are needed to reduce occupational hand eczema. We describe the design of a randomised clinical trial to investigate the effects of classification of hand eczema plus individual counselling versus no intervention. The trial includes health-care workers with hand eczema identified from a self-administered questionnaire delivered to 3181 health-care workers in three Danish hospitals. The questionnaire identifies the prevalence of hand eczema, knowledge of skin-protection, and exposures that can lead to hand eczema. At entry, all participants are assessed regarding: disease severity (Hand Eczema Severity Index); self-evaluated disease severity; number of eruptions; quality of life; skin protective behaviour, and knowledge of skin protection. The patients are centrally randomised to intervention versus no intervention 1:1 stratified for hospital, profession, and severity score. The experimental group undergoes patch and prick testing; classification of the hand eczema; demonstration of hand washing and appliance of emollients; individual counselling, and a skin-care programme. The control group receives no intervention. All participants are reassessed after six months. The primary outcome is observer-blinded assessment of disease severity and the secondary outcomes are unblinded assessments of disease severity; number of eruptions; knowledge of skin protection; skin-protective behaviour, and quality of life. The trial is registered in ClinicalTrials.Gov, NCT01012453.

Hand eczema is a disease frequently observed in dermatological practice. This condition has negative emotional, social, and psychological effects due to its impact on daily life and morphological appearance. Due to its considerable effect on the quality of life, this disease can lead to depression. However, not many studies have been performed on the quality of life and depression in hand eczema patients. The purpose of this study is to investigate the association between the quality of life, depression, and disease severity in hand eczema patients in South Korea. A total of 138 patients with hand eczema participated in this study. The patients' quality of life was assessed by a self-administered questionnaire using the Dermatology Life Quality Index (DLQI). Data on patients suffering from depression was obtained using the Beck's Depression Inventory (BDI-II). The disease severity was determined during the clinical examination, according to the Hand Eczema Severity Index (HECSI). We found positive associations between DLQI and HECSI scores (p<0.05). BDI-II scores had also statistically positive correlations with HECSI scores (p<0.05). DLQI and BDI-II scores both increased with disease severity. Hand eczema negatively affected the quality of life and mood of patients relative to the disease severity. Therefore, we suggest that quality of life modification and emotional support should be included as a part of treatment for hand eczema.

Identification of subjects at risk for contact dermatitis by screening tests is desirable in order to adjust the preventive measures to individual skin susceptibility. The present study aimed to examine the effects of basic physiological features, such as baseline electrical impedance (IMP) and transepidermal water loss (TEWL), on reactivity to sodium lauryl sulphate (SLS). On the basis of two previous studies, we re-evaluated the experimental irritant skin reactions (50 microL of 2% SLS in large Finn Chambers for 24 h) on the volar forearms of 29 patients with eczema and 19 healthy controls. We found definite differences in the baseline values of IMP, between the patients and the controls. Moreover, patients with eczema showed higher TEWL and lower MIX values on day 3 after exposure to SLS, which may indicate differences in SLS reactivity. After the study, the biophysical parameters of the eczema patients did not return to baseline, which suggests that their skin heals more slowly than that of normal subjects. Our findings indicate that the IMP technique may help to 'detect' chemically vulnerable skin. However, more studies are needed to determine the value of the basal electrical impedance parameters in assessing the risk of developing irritant contact dermatitis.

Knowledge on Staphylococcus aureus colonization rates and epidemiology in hand eczema is limited. The aim of this study was to clarify some of these issues. Samples were collected by the "glove juice" method from the hands of 59 patients with chronic hand eczema and 24 healthy individuals. Swab samples were taken from anterior nares and throat from 43 of the 59 patients and all healthy individuals. S. aureus were spa typed and analysed by DNA-microarray-based genotyping. The extent of the eczema was evaluated by the hand eczema extent score (HEES). The colonization rate was higher on the hands of hand eczema patients (69 %) compared to healthy individuals (21 %, p < 0.001). This was also seen for bacterial density (p = 0.002). Patients with severe hand eczema (HEES ≥ 13) had a significantly higher S. aureus density on their hands compared to those with milder eczema (HEES = 1 to 12, p = 0.004). There was no difference between patients and healthy individuals regarding colonization rates in anterior nares or throat. spa typing and DNA-microarray-based genotyping indicated certain types more prone to colonize eczematous skin. Simultaneous colonization, in one individual, with S. aureus of different types, was identified in 60-85 % of the study subjects. The colonization rate and density indicate a need for effective treatment of eczema and may have an impact on infection control in healthcare.

The individual burden of disease in hand eczema patients is considerable. However, little is known about the socio-economic impact of this disease. The aims of this review were to evaluate the literature on cost-of-illness in hand eczema, and to compose a checklist for future use. The literature was retrieved from the MEDLINE and EMBASE databases up to October 2015. Quality evaluation was based on seven relevant items in cost-of-illness studies. Cost data (direct and indirect) were extracted and converted into euros (2014 price level) by use of the Dutch Consumer Price Index. Six articles were included. The mean annual total cost per patient ranged from €1311 [corrected] to €9792 (direct cost per patient, €521 to €3722; [corrected] and indirect cost per patient, €100 to €6846). Occupational hand eczema patients showed indirect costs up to 70% of total costs, mainly because of absenteeism. A large diversity in hand eczema severity was found between studies. The socio-economic burden of hand eczema is considerable, especially for more severe and/or occupational hand eczema. Absenteeism from paid work leads to a high total cost-of-illness, although disregard of presenteeism often leads to underestimation of indirect costs. Differences in included cost components, the occupational status of patients and hand eczema severity make international comparison difficult. A checklist was added to standardize the approach to cost-of-illness studies in hand eczema. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Eczema is a chronic, itchy skin condition that can have a large impact on the quality of life of patients and their families. People with eczema are often keen to try out non-pharmacological therapies like silk therapeutic garments that could reduce itching or the damage caused by scratching. However, the effectiveness and cost-effectiveness of these garments in the management of eczema has yet to be proven. The CLOTHES Trial will test the hypothesis that 'silk therapeutic garments plus standard eczema care' is superior to 'standard care alone' for children with moderate to severe eczema. Parallel group, observer-blind, pragmatic, multi-centre randomised controlled trial of 6 months' duration. Three hundred children aged 1 to 15 years with moderate to severe eczema will be randomised (1:1) to receive silk therapeutic garments plus standard eczema care, or standard eczema care alone. Primary outcome is eczema severity, as assessed by trained and blinded investigators at 2, 4 and 6 months (using the Eczema Area and Severity Index (EASI)). Secondary outcomes include: patient-reported eczema symptoms (collected weekly for 6 months to capture long-term control); global assessment of severity; quality of life of the child, family and main carer; use of standard eczema treatments (emollients, corticosteroids applied topically, calcineurin inhibitors applied topically and wet wraps); frequency of infections; and cost-effectiveness. The acceptability and durability of the clothing will also be assessed, as will adherence to wearing the garments. A nested qualitative study will assess the views of a subset of children wearing the garments and their parents, and those of healthcare providers and commissioners. Randomisation uses a computer-generated sequence of permuted blocks of randomly varying size, stratified by recruiting hospital and child's age (< 2 years; 2 to 5 years; > 5 years), and concealed using a secure web-based system. The sequence of treatment allocations will remain concealed until randomisation and data collection are complete. Recruitment is taking place from November 2013 to May 2015, and the trial will be completed in 2016. Full details of results will be published in the National Institute for Health Research Journal series. Current Controlled Trials ISRCTN77261365 (registered 11 November 2013).

Atopic eczema is a common childhood disease associated with high IgE and eosinophilia. We characterized the clinical features associated with hyper-IgE (defined as IgE > 2000 IU/L) in eczema. Nottingham Eczema Severity Score (NESS), family and personal history of atopy, skin prick test (SPT) for common food and aeroallergens, highest serum IgE ever and eosinophil counts were evaluated in 330 children eczema patients. Childhood-NESS (NESS performed at <10 years of age) and adolescent-NESS (NESS performed at >10 years of age) were further analyzed. IgE correlated with NESS (spearman coefficient 0.35, p < 0.001) and eosinophil percentage (spearman coefficient 0.56, p = 0.001). Compared with IgE ≤ 2000IU/L (n = 167), patients with hyper-IgE (n = 163) were associated with male gender (p = 0.002); paternal atopy (p = 0.026); personal history of atopic rhinitis (p = 0.016); asthma (p < 0.001); dietary avoidance (p < 0.001); use of wet wrap (p < 0.001); traditional Chinese medicine use (TCM, p < 0.001); immunomodulant use (azathioprine or cyclosporine, p < 0.001); skin prick sensitization by dust mites (p < 0.001), cats (p = 0.012), dogs (p = 0.018), food (p = 0.002); eosinophilia (p < 0.001); more severe disease during childhood (p < 0.0001) and during adolescence (p < 0.0001), but not onset age of eczema or maternal atopy. Logistic regression showed that hyper-IgE was associated with personal history of asthma (exp(B) = 5.12, p = 0.002) and eczema severity during childhood and adolescence (p < 0.001). For patients <10 years of age, dust mite sensitization (p = 0.008) was associated with hyper-IgE. For patients >10years of age, food allergen sensitization was associated with hyper-IgE (p = 0.008). Hyper-IgE is independently associated with asthma, more severe atopy and more severe eczema during childhood and adolescence. IgE > 2000 IU/L may be a tool to aid prognostication of this chronic relapsing dermatologic disease and its progression to asthma.

The University Medical Centre Utrecht (UMC Utrecht) has developed an eczema portal that combines e-consulting, monitoring and self-management training by a dermatology nurse online for patients and parents of young children with atopic dermatitis (AD). Patient satisfaction with the portal was high. It could be extended to become a Digital Eczema Centre for multidisciplinary collaboration between health-care providers from different locations and the patient. Before starting the construction of the Digital Eczema Centre, the feasibility was examined by carrying out a business case analysis. The purposes, strength and weaknesses showed that the Digital Eczema Centre offered opportunities to improve care for patients with AD. The financial analysis resulted in a medium/best case scenario with a positive result of euro50-240,000 over a period of five years. We expect that the Digital Eczema Centre will increase the accessibility and quality of care. The web-based patient record and the digital chain-of-care promote the involvement of patients, parents and multidisciplinary teams as well as the continuity and coordination of care.

Purposes. The present paper reports clinical cases where nummular eczema developed during the course of breast reconstruction by means of implantation and evaluates the occurrence patterns and ratios of this complication. Methods. 1662 patients undergoing breast reconstruction were reviewed. Patients who developed nummular eczema during the treatment were selected, and a survey was conducted on these patients regarding three items: (1) the stage of the treatment at which nummular eczema developed; (2) time required for the lesion to heal; (3) location of the lesion on the reconstructed breast(s). Furthermore, histopathological examination was conducted to elucidate the etiology of the lesion. Results. 48 patients (2.89%) developed nummular eczema. The timing of onset varied among these patients, with lesions developing after the placement of tissue expanders for 22 patients (45.8%); after the tissue expanders were replaced with silicone implants for 12 patients (25%); and after nipple-areola complex reconstruction for 14 patients (29.2%). Nummular eczema developed both in periwound regions (20 cases: 41.7%) and in nonperiwound regions (32 cases: 66.7%). Histopathological examination showed epidermal acanthosis, psoriasiform patterns, and reduction of sebaceous glands. Conclusions. Surgeons should recognize that nummular eczema is a potential complication of breast reconstruction with tissue expanders and silicone implants. PMID:26380109

Atopy patch testing is a useful way to determine delayed-type hypersensitivity reactions to foods and aeroallergens. Although food additives have been accused of worsening atopic eczema symptoms, according to recent studies the role of food additives in atopic eczema remains unclear. The purpose of our study was to investigate food additive hypersensitivity in a group of children with atopic eczema by using standardized atopy patch testing and to determine the role of food additive hypersensitivity in atopic eczema. Thirty-four children with atopic eczema and 33 healthy children were enrolled in the study. Children who consumed foods containing additives and did not use either antihistamines or local or systemic corticosteroids for at least 7 days prior to admission were enrolled in the study. All children were subjected to atopy patch testing and after 48 and 72 hours their skin reactions were evaluated by using the guidelines. Positive atopy patch test results were significantly higher in the atopic eczema group. Forty-one percent of the atopic eczema group (n = 14) and 15.2% (n = 5) of the control group had positive atopy patch test results with food additives (p = 0.036) (estimated relative risk 1.68, case odds 0.7, control odds 0.17). Carmine hypersensitivity and the consumption of foods containing carmine, such as gumdrops, salami, and sausage, were significantly higher in the children with atopic eczema. This is the first study investigating hypersensitivity to food additives in children with atopic eczema. Our results indicate that carmine may play a role in atopic eczema. © 2015 Wiley Periodicals, Inc.

The Patient-Oriented Eczema Measure in young children: responsiveness and minimal clinically important difference.

The Patient-Oriented Eczema Measure (POEM) has been recommended as the core patient-reported outcome measure for trials of eczema treatments. Using data from the Choice of Moisturiser for Eczema Treatment randomized feasibility study, we assess the responsiveness to change and determine the minimal clinically important difference (MCID) of the POEM in young children with eczema. Responsiveness to change by repeated administrations of the POEM was investigated in relation to change recalled using the Parent Global Assessment (PGA) measure. Five methods of determining the MCID of the POEM were employed; three anchor-based methods using PGA as the anchor: the within-patient score change, between-patient score change and sensitivity and specificity method, and two distribution-based methods: effect size estimate and the one half standard deviation of the baseline distribution of POEM scores. Successive POEM scores were found to be responsive to change in eczema severity. The MCID of the POEM change score, in relation to a slight improvement in eczema severity as recalled by parents on the PGA, estimated by the within-patient score change (4.27), the between-patient score change (2.89) and the sensitivity and specificity method (3.00) was similar to the one half standard deviation of the POEM baseline scores (2.94) and the effect size estimate (2.50). The Patient-Oriented Eczema Measure as applied to young children is responsive to change, and the MCID is around 3. This study will encourage the use of POEM and aid in determining sample size for future randomized controlled trials of treatments for eczema in young children. © 2016 The Authors.

Human diet planning is conducted by choosing appropriate food items that fulfill the nutritional requirements into the diet formulation. This paper discusses the application of integer programming to build the mathematical model of diet planning for eczema patients. The model developed is used to solve the diet problem of eczema patients from young age group. The integer programming is a scientific approach to select suitable food items, which seeks to minimize the costs, under conditions of meeting desired nutrient quantities, avoiding food allergens and getting certain foods into the diet that brings relief to the eczema conditions. This paper illustrates that the integer programming approach able to produce the optimal and feasible solution to deal with the diet problem of eczema patient.

The atopy patch test (APT) was proposed to evaluate IgE-mediated sensitizations in patients with atopic eczema (AE). The prevalence and agreement with clinical history and specific IgE (sIgE) of positive APT reactions was investigated in six European countries using a standardized method. A total of 314 patients with AE in remission were tested in 12 study centers on clinically uninvolved, non-abraded back skin with 200 index of reactivity (IR)/g of house dust mite Dermatophagoides pteronyssinus, cat dander, grass, and birch pollen allergen extracts with defined major allergen contents in petrolatum. Extracts of egg white, celery and wheat flour with defined protein content were also patch tested. APT values were evaluated at 24, 48, and 72 h according to the European Task Force on Atopic Dermatitis (ETFAD) guidelines. In addition, skin-prick test (SPT) and sIgE and a detailed history on allergen-induced eczema flares were obtained. Previous eczema flares, after contact with specific allergens, were reported in 1% (celery) to 34% (D. pteronyssinus) of patients. The frequency of clear-cut positive APT reactions ranged from 39% with D. pteronyssinus to 9% with celery. All ETFAD intensities occured after 48 and 72 h. Positive SPT (16-57%) and elevated sIgE (19-59%) results were more frequent. Clear-cut positive APT with all SPT and sIgE testing negative was seen in 7% of the patients, whereas a positive APT without SPT or sIgE for the respective allergen was seen in 17% of the patients. APT, SPT and sIgE results showed significant agreement with history for grass pollen and egg white (two-sided Pr > /Z/ < or = 0.01). In addition, SPT and sIgE showed significant agreement with history for the other aeroallergens. With regard to clinical history, the APT had a higher specificity (64-91% depending on the allergen) than SPT (50-85%) or sIgE (52-85%). Positive APT were associated with longer duration of eczema flares and showed regional differences. In 10 non-atopic controls, no positive APT reaction was seen. Aeroallergens and food allergens are able to elicit eczematous skin reactions after epicutaneous application. As no gold standard for aeroallergen provocation in AE exists, the relevance of aeroallergens for AE flares may be evaluated by APT in addition to SPT and sIgE. The data may contribute to the international standardization of the APT.

The major theory implicating diet with allergic diseases is associated with altered food consumption and subsequent changes in fatty acid composition. To investigate fatty acid compositions among infants with atopic and non-atopic eczema and healthy infants and to evaluate the expediency of non-invasive cheek cell phospholipid fatty acid composition as a marker in patients with eczema. Diagnosis of eczema in infants was confirmed clinically and by positive (atopic eczema, n=6) or negative (non-atopic eczema, n=6) skin prick testing in comparison with controls (n=19). The fatty acid compositions of infant cheek cell and serum phospholipids and breast milk total lipids were analysed by gas chromatography. The distinction between atopic and non-atopic eczema was manifested in cheek cell phospholipids as linoleic acid (14.69 (13.67-15.53)% of total fatty acids; the median (interquartile range)), the sum of n-6 fatty acids (19.94 (19.06-20.53)%) and the sum of polyunsaturated fatty acids (22.70 (21.31-23.28)%) were higher in infants with atopic eczema compared with non-atopic eczema (12.69 (10.87-13.93); 17.72 (15.63-18.91) and 19.90 (17.64-21.06), respectively; P<0.05) and controls (12.50 (12.16-13.42); 18.19 (17.43-18.70) and 20.32 (19.32-21.03), respectively; P<0.05). Serum phospholipid gamma-linolenic acid was lower in both atopic and non-atopic eczema compared with controls (P<0.05) and additionally eicosapentaenoic acid was higher in atopic eczema compared with controls (P<0.05). These preliminary results suggest differences in fatty acid compositions between the two types of eczema, calling for further evaluation in a larger setting. The two types of eczema may be regulated by different immunological processes, and fatty acids may have a more profound role in the atopic type.

Introduction Contact eczema is a common skin condition with complex etiology, variable clinical presentation and lengthy therapy duration. The mechanism of contact eczema is complex, since it is affected by multiple inflammatory mediators. Aim To assess concentrations of metalloproteinase 2 (MMP-2), metalloproteinase 9 (MMP-9) and granzyme B (GzmB) in patients with contact eczema. Material and methods Seventy patients with contact eczema and 30 healthy persons as controls were included in the study. In all subjects, MMP-2, MMP-9 and GzmB were determined using ELISA immunoassay. In study group patients, concentrations were assayed in periods of disease exacerbation and remission. Obtained results were analyzed statistically. Results Mean MMP-2 and GzmB concentrations were found to be significantly higher in the study group than in the control group. Mean MMP-2, MMP-9 and GzmB levels were also statistically significantly higher during skin lesion relapse compared to contact eczema remission periods. Conclusions The presented paper demonstrates that MMP-2, MMP-9 and GzmB are good markers of contact eczema exacerbations. PMID:24278051

Chronic skin diseases like eczema may lead to severe health and financial consequences for patients if not detected and controlled early. Early measurement of disease severity, combined with a recommendation for skin protection and use of appropriate medication can prevent the disease from worsening. Current diagnosis can be costly and time-consuming. In this paper, an automatic eczema detection and severity measurement model are presented using modern image processing and computer algorithm. The system can successfully detect regions of eczema and classify the identified region as mild or severe based on image color and texture feature. Then the model automatically measures skin parameters used in the most common assessment tool called "Eczema Area and Severity Index (EASI)," by computing eczema affected area score, eczema intensity score, and body region score of eczema allowing both patients and physicians to accurately assess the affected skin.

Acitretin has been used off-label for years to treat chronic hand eczema, but acitretin is less often prescribed as alitretinoïne was approved. This study evaluates both retinoids in a daily practice cohort of patients with severe chronic hand eczema in terms of drug survival and reasons for discontinuation. Patients using alitretinoin or acitretin between 01-01-1994 and 01-08-2015 were included in this retrospective daily practice study and analyzed by Kaplan-Meier drug survival curves. Potential determinants were analyzed by Cox regression analyses. Ninety-five patients were treated with alitretinoin and 109 patients with acitretin. The main reasons for discontinuation were adverse events and cleared hand eczema, 29.5 and 27.4% in alitretinoin versus 43.1 and 23.9% in acitretin. Patients with hyperkeratotic hand eczema had most often a good effect of treatment: 68.3% in alitretinoin and 50.7% in acitretin treatment. The drug survival rates of alitretinoin and acitretin after 12, 24, 36, and 52 weeks were 69.3, 45.1, 19.6, 7.0% and 74.3, 45.5, 33.8, 23.2%, respectively. Alitretinoin and acitretin are effective treatment options for patients with hand eczema. However, both treatments were more effective in patients with hyperkeratotic hand eczema. Fewer patients discontinued alitretinoin compared with acitretin due to adverse events. © 2016 Wiley Periodicals, Inc.

Health-related quality of life (HRQOL) is widely used as a patient-reported outcome to evaluate clinical trials. In routine care it can also be used to improve treatment strategies or to enhance patients' self-awareness and empowerment. Therefore a disease-specific instrument is needed that assesses in detail all the impairments caused by the disease of interest. For patients with hand eczema (HE) such an instrument was developed by an international expert group, but its measurement properties are unknown. To validate the German version of the Quality of Life in Hand Eczema Questionnaire (QOLHEQ), which covers the domains of (i) symptoms, (ii) emotions, (iii) functioning and (iv) treatment and prevention. The QOLHEQ was assessed up to three times in 316 patients with HE to test reliability and sensitivity to change. To test construct validity we also assessed several reference measures. The scale structure was analysed using the Rasch model for each subscale and a structural equation model was used to test the multi domain structure of the QOLHEQ. After minor adaptions of the scoring structure, all four subscales of the QOLHEQ did not significantly misfit the Rasch model (α > 0·05). The fit indices of the structural equation model showed a good fit of the multi domain construct with four subscales assessing HRQOL. Nearly all a priori-defined hypotheses relating to construct validity could be confirmed. The QOLHEQ showed a sensitivity to change that was superior compared with all reference measures. The QOLHEQ is ready to be used in its German version as a sensitive outcome measure in clinical trials and for routine monitoring. The treatment-relevant subscales enable its use to enhance patients' self-awareness and to monitor treatment decisions. © 2014 British Association of Dermatologists.

Chronic hand eczema is a common dermatological disorder of multifactorial aetiology. It affects physical, material, social and psychological aspects of life, thereby impairing health-related quality of life. The aim of the present study was to assess quality of life, anxiety, depression and obsessive-compulsive tendencies in patients with chronic hand eczema. Seventy-one patients with chronic hand eczema were included in the study. Quality of life was evaluated according to the Dermatology Life Quality Index (DLQI). Patients were also assessed for anxiety and depression with the Hospital Anxiety and Depression Scale (HADS), and for compulsive behaviour with the Leyton Trait Scale. The DLQI score was 11.11 ± 1.81 in patients with chronic hand eczema. Scores on the Leyton Trait Scale were significantly higher than those of healthy controls (p < 0.027). As concerns the HADS-Anxiety subscale, patients with hand dermatitis had statistically significantly higher scores than those of volunteers (p = 0.002). In contrast, no statistically significant difference was found between the two groups with regard to the HADS-Depression subscale score and total HADS score. Hand eczema treatment should address the severity of skin lesions as well as the psychological impact of hand eczema. © 2015 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

The increasing prevalence and impact of atopic eczema in children in Western countries such as Australia substantiate the need to evaluate the current management of this illness. It has been well documented that the most important aspects in the management of atopic eczema are to allow adequate time for education and demonstration of treatments. However, current models of healthcare funding restrict the opportunity for patient education during medical consultation times. The contribution of nursing to patient care through nurse-led clinics has significant potential in the management of many common chronic illnesses, although atopic eczema has received minimal attention by researchers to date. To discuss the current clinical management of atopic eczema, and to identify the evidence surrounding the benefits of nurse-led clinics in managing patients with chronic illnesses. Systematic searches were undertaken using the Cochrane Library, MedLine, PUBMed and CINAHL from 1995 to 2005. Manual searches of references of retrieved articles identified two additional key studies from 1990 and 1993 which were also included in the review. In total, 22 relevant publications were identified. These included both primary research and descriptive studies that covered the medical management of eczema, patient education and improved patient outcomes. The evidence emerging from the literature indicates that the current management of eczema through doctor-led clinics could be improved, with doctors often lacking the time to offer sufficient patient education to manage chronic illnesses effectively. The literature supports the efficacy of nurse-led clinics in the management of chronic illnesses. The benefits of nurse-led clinics include increased patient satisfaction, longer consultations resulting in improved patient education and similar health outcomes when compared with care from a doctor. No studies were identified comparing nurse-led and doctor-led clinics in the management of eczema. The most effective way to manage atopic eczema is to provide adequate time for education and demonstration of treatments, which the literature suggests can be achieved through nurse-led clinics. The literature review supports an investigation researching the outcomes of a nurse-led clinic on reducing the severity of eczema in children.

The essential physical role, visibility and social importance of the hands place a major psychological burden on patients with hand eczema. The aim of this study was to identify the psychological, social and clinical characteristics of patients with hand eczema, in particular the prevalences of depression, anxiety, suicidal ideation, and comorbidities. Data on patients with hand eczema were analysed from a large European multicentre study conducted with dermatology outpatients from 13 countries. Groups of patients and controls were compared to analyse the psychological burden of hand eczema. Female patients with hand eczema had higher Hospital Anxiety and Depression Scale (HADS) scores for anxiety (n = 86, median = 7.0) than controls (n = 900, median = 5.0, P = .02), and for depression (median = 4.0) than controls (3.0, P < .001). Patients with high suicidal ideation, with low socioeconomic status and who were widowed or divorced were more likely to fulfil the HADS criteria for anxiety [odds ratio (OR) > 1, P = .038, P < .001, and P < .001, respectively]. The median Dermatology Life Quality Index score was 7.0 (n = 68). This study identifies a specific psychological burden experienced by hand eczema patients, highlighting the need for focused psychosocial interventions. Physicians in particular should be aware of the need to identify anxiety and depression in female patients. © 2018 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Patients actively seek information about how to cope with their health problems, but the quality of the information available varies. A number of instruments have been developed to assess the quality of patient information, primarily though in English. Little is known about the reliability of these instruments when applied to patient information in German. The objective of our study was to investigate and compare the reliability of two validated instruments, DISCERN and EQIP, in order to determine which of these instruments is better suited for a further study pertaining to the quality of information available to German patients with eczema. Two independent raters evaluated a random sample of 20 informational brochures in German. All the brochures addressed eczema as a disorder and/or therapy options and care. Intra-rater and inter-rater reliability were assessed by calculating intra-class correlation coefficients, agreement was tested with weighted kappas, and the correlation of the raters’ scores for each instrument was measured with Pearson’s correlation coefficient. DISCERN demonstrated substantial intra- and inter-rater reliability. It also showed slightly better agreement than EQIP. There was a strong correlation of the raters’ scores for both instruments. The findings of this study support the reliability of both DISCERN and EQIP. However, based on the results of the inter-rater reliability, agreement and correlation analyses, we consider DISCERN to be the more precise tool for our project on patient information concerning the treatment and care of eczema.

Substance P (SP) was reported to be associated with eczema and acts as a potent skin mast cell secretagogue. However, little is known of its expression in inflammatory cells in eczema and its ability in induction of mast cell accumulation. In the present study, we investigated expression of SP and neurokinin-1 receptor (NK1R) on peripheral blood leukocytes and mast cells from patients with eczema and influence of SP on mast cell accumulation by using flow cytometry analysis, trans-epithelial cell migration assay and mouse peritoneal model. The results showed that plasma SP and IL-17A levels in eczema patients were higher than that in healthy control subject. The percentages of SP+ and NK1R+ expression populations of monocytes, helper T cells, natural killer T cells and basophils in peripheral blood of eczema patients were markedly elevated. It was observed that not only absolute number of mast cells but also SP+ and NK1R+ mast cells are enhanced in the lesion skin of eczema. SP showed a potent chemoattractant action on mast cells as assessed by a mouse peritoneal model and a trans-endothelium cell migration assay. SP-induced mast cell accumulation appears a CD18/CD11a complex, L-selectin and ICAM-1-dependent event which can be blocked by a NK-1R antagonist RP67580. In conclusion, elevated expression of SP in patients with eczema and the ability of SP in induction of mast cell accumulation indicate strongly that SP is a potent proinflammatory mediator, which contributes to the pathogenesis of eczema. Inhibitors of SP and blockers of NK1R are likely useful agents for treatment of eczema.

Eczema is a common chronic or chronically relapsing skin disease that has a substantial impact on quality of life (QoL). By means of a consensus-based process, the Harmonising Outcome Measures in Eczema (HOME) initiative has identified QoL as one of the four core outcome domains to be assessed in all eczema trials (Allergy 67(9):1111-7, 2012). Various measurement instruments exist to measure QoL in adults with eczema, but there is a great variability in both content and quality (for example, reliability and validity) of the instruments used, and it is not always clear if the best instrument is being used. Therefore, the aim of the proposed research is a comprehensive systematic assessment of the measurement properties of the existing measurement instruments that were developed and/or validated for the measurement of patient-reported QoL in adults with eczema. This study is a systematic review of the measurement properties of patient-reported measures of QoL developed and/or validated for adults with eczema. Medline via PubMed and EMBASE will be searched using a selection of relevant search terms. Eligible studies will be primary empirical studies evaluating, describing, or comparing measurement properties of QoL instruments for adult patients with eczema. Eligibility assessment and data abstraction will be performed independently by two reviewers. Evidence tables will be generated for study characteristics, instrument characteristics, measurement properties, and interpretability. The quality of the measurement properties will be assessed using predefined criteria. Methodological quality of studies will be assessed using the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) checklist. A best evidence synthesis will be undertaken if more than one study has investigated a particular measurement property. The proposed systematic review will produce a comprehensive assessment of measurement properties of existing QoL instruments in adult patients with eczema. We aim to identify one best currently available instrument to measure QoL in eczema patients. PROSPERO CRD42015017138.

Atopic and Non-atopic Eczema.

Rożalski, Michał; Rudnicka, Lidia; Samochocki, Zbigniew

2016-06-01

Atopic dermatitis is a common term used in the medical literature, but according to The Nomenclature Review Committee Of The World Allergy Organization the name which should be used is eczema. Eczema is divided into two subtypes: atopic and non-atopic. These subtypes differ in the level of total immunoglobulin E (IgE) in serum, response to allergens in skin prick tests, and detection of specific IgE antibodies. Non-atopic eczema is characterized by a low level of total IgE, negative skin prick tests, and undetectable specific IgE antibodies. It is estimated that 10-45% cases of eczema are non-atopic ones. In recent studies, other features differentiating these two subtypes have been identified, such as female predominance in non-atopic eczema. A more severe course, damage of the epidermal barrier, predominance of Th2 (T helper cells 2) response, and a lower positive reaction to metal patch tests are the characteristics of the atopic subtype. In our opinion, new diagnostic criteria taking into account the non-atopic subtype of eczema need to be established.

Face-masks for facial atopic eczema: consider a hydrocolloid dressing.

PubMed

Rademaker, Marius

2013-08-01

Facial involvement of atopic eczema in young children can be difficult to manage. Chronic scratching and rubbing, combined with parental reluctance to use topical corticosteroids on the face, often results in recalcitrant facial eczema. While wet wraps are a useful management option for moderate/severe atopic eczema involving the trunk and limbs they are difficult to use on the face. We describe the use of a face-mask using a widely available adhesive hydrocolloid dressing (DuoDerm extra thin) in three children with recalcitrant facial atopic eczema. Symptomatic control of itch or soreness was obtained within hours and the facial atopic eczema was markedly improved by 7 days. The face-masks were easy to apply, each lasting 1-4 days. One patient had a single adjuvant application of a potent topical corticosteroid under the hydrocolloid dressing. All three patients had long remissions (greater than 3 months) of their facial eczema, although all continued to have significant eczema involving their trunk and limbs. Face-masks made from hydrocolloid dressings, with or without topical corticosteroids, are worth considering in children with recalcitrant facial eczema. © 2012 The Author.

IL-18 has been found to be associated with eczema. However, little is known of the role of IL-18 binding protein (BP) and IL-18 receptor (R) in eczema. We therefore investigated the expression of IL-18, IL-18BP, and IL-18R on mast cells by using flow cytometry analysis and mouse eczema model. The results showed that plasma free IL-18 and free IL-18BP levels in eczema patients were higher than those in healthy controls. IL-18 provoked up to 3.1-fold increase in skin mast cells. IL-18 induced also an increase in IL-18BP+ mast cells, but a reduction of IL-18R+ mast cells in mouse eczema skin. It was found that house dust mite allergen Der p1 and egg allergen OVA induced upregulation of the expression of IL-18, IL-18BP, and IL-18R mRNAs in HMC-1 cells following 2 and 16 h incubation. In conclusion, correlation of IL-18 and IL-18BP in eczema plasma suggests an important balance between IL-18 and IL-18BP in eczema. The decrease in molar concentration ratio of plasma IL-18BP/IL-18 and allergen-induced upregulated expression of IL-18 and IL-18R in skin mast cells of the patients with eczema suggests that anti-IL-18 including IL-18BP therapy may be useful for the treatment of eczema.

The presence of chronic disease is a risk factor for the development of mood disturbances and panic disorders. They can influence the course of disease and effectiveness of therapy. Depression may be the cause of making light doctor's advice. Anxious patients often aggravate symptoms of the disease. To study symptoms of anxiety and depression in patients suffering from atopic eczema/dermatitis syndrome (ZAZS). Material. We studied 38 patients suffering from adequately controlled moderate ZAZS and 62 volunteers in the control group. Mental status of subjects was assessed by means of State and Trait Anxiety Inventory (STAI) and Beck Depression Inventory (BDI) questionnaires. ZAZS patients demonstrated higher intensity of anxiety (as a trait and as a state) than healthy subjects. Intensity and prevalence of depression in the atopic eczema/ dermatitis syndrome group was higher than in the control group. Patients suffering from atopic/eczema dermatitis syndrome are pre-disposed to anxiety and depression manifestation. Even adequately controlled symptoms of atopic/eczema dermatitis syndrome may be the cause of those disturbances' occurrence.

Misunderstanding and stigmatisation are common problems encountered by patients with hand eczema. Various misconceptions about the disease circulate in the general population. Although hand eczema has gained more attention in dermatology during the past years, information on public perception of the disease is still lacking. The aim of our study was to investigate perception of and level of knowledge on the subject hand eczema. There were 624 patients included from 2 general medicine practices and 2 dermatological practices. A self-administered questionnaire was filled out by the participants, covering issues on history of hand eczema, level of knowledge and attitude towards a clinical photograph of hand eczema. We found that a larger proportion of individuals from dermatological practice were more familiar with hand eczema as a disease than those from general medical practice. Women knew significantly more about and had a more positive perception of the disease than men. Our results imply that the level of knowledge on hand eczema in the general public is rather low and influenced by prejudice.

Summary Background Atopic eczema is characterized by Th2-dominant immunity with the cytokine interleukin 13 and the transcription factor GATA binding protein 3 playing a critical role. Objectives We assessed the association of polymorphisms in the IL13 and GATA3 genes with childhood eczema. Methods A birth cohort (n = 1456) was established on the Isle of Wight in 1989 and followed at the ages of 1 (n = 1167), 2 (n = 1174), 4 (n = 1218) and 10 years (n = 1373) to determine the prevalence of allergic disease including eczema. At 4 and 10 years, skin prick testing was performed. Whole blood samples (n = 923) were obtained at the 10-year assessment, stored frozen, and genotyped. Five polymorphisms from IL13 and seven from GATA3 were genotyped for this analysis. Repeated measurement analyses were conducted for the occurrence of eczema at ages 1, 2, 4 and 10 years. All analyses were adjusted for maternal and paternal eczema, low birth weight (< 2500 g), breastfeeding ≥ 3 months and age. Results IL13 was not associated with childhood eczema. For GATA3, the single nucleotide polymorphism (SNP) rs2275806 (promoter region) showed an increased odds ratio for atopic eczema independent of whether the comparison group had a positive skin prick test. The SNP rs444762 (intron 3 region) was associated with atopic eczema in comparison with children without eczema. The increased relative risks remained significant after adjustment for multiple testing only for rs2275806 (P < 0Æ05). Conclusions A SNP in GATA3 is associated with atopic eczema. This finding highlights the importance of GATA3 as an immune-modulating gene in atopic eczema. PMID:18410415

The aim of this study was to explore the use of complementary and alternative medicine (CAM) therapies in patients with acne, psoriasis, or atopic eczema and the attitudes about CAM of these patients. This was a qualitative study, utilizing semistructured interviews and thematic analysis. Patients were recruited from the practices of dermatologists and general practitioners in a noncapital Australian city. Twenty-six (26) interviews were conducted with patients with acne, 29 with psoriasis, and 7 with atopic eczema. Use of CAM therapies was common. Participants tended to value CAM over orthodox therapies because of their preference for natural approaches to their skin diseases and the perceived lesser potential for adverse effects of CAM therapies. Respondents with acne were more confident about the efficacy of CAM than were those with psoriasis or eczema. The resulting sense of control attenuated psychologic sequelae of acne. This was not apparent in psoriasis or eczema. Practitioners should be cognizant of the likely use of CAM and its implications (including the potential for attenuation of psychologic morbidity) in their patients who have skin diseases.

Topical glucocorticoids (GCs) are the mainstay of treatment for eczema, but GC phobia and fears are very common among the parents of paediatric patients. To survey the nature and extent of "fears" of GC use, and to evaluate if disease severity is associated with such fears. Patients with eczema managed in the paediatric dermatology outpatient clinic of a university hospital were recruited in this survey. Disease severity and various aspects of belief and practices of GC use were assessed with the Nottingham Eczema Severity Score and a questionnaire. GC "fears" were present in two fifths of informants with non-eczematous skin disease and mild eczema, but three fifths in moderate-to-severe disease. Requests for steroid-sparing medications (such as tacrolimus or pimecrolimus) had been made in nearly 50% of cases with moderate-to-severe eczema, and many parents would wait until eczema had worsened or apply GC only as a last resort to avoid potential side effects. "Fears" were predominantly interpersonal and rarely iatrogenic in nature. Skin problems (in particular skin thinning) and adverse effects on growth were the side effects of GC of most concern. However, fewer than half of the informants had discussed their concerns with doctors. Our results suggest the importance of understanding the nature and extent to which GC fears, regardless of eczema severity, are prevalent so that sound advice can be offered in a timely manner to parents and patients.

Allergic responses are enhanced by stress, whereas they are reduced by laughter in atopic eczema patients. Emotion with tears decreases plasma IL-6 levels in patients with rheumatoid arthritis. Thus, the effect of emotion with tears on allergic responses in patients with atopic eczema was studied. Sixty patients with atopic eczema having latex allergy viewed both the weather information video and the heart-warming movie, Kramer vs. Kramer. Just before and immediately after viewing each video, allergic responses to latex were measured. Viewing the weather information video did not cause emotion with tears in any patients, and it failed to modulate allergic responses. In contrast, viewing Kramer vs. Kramer caused emotion with tears in 44 of 60 patients, and it reduced allergic skin wheal responses to latex and latex-specific IgE production in them. Emotion with tears reduced allergic responses, and it may be useful in the treatment of allergic diseases.

Clinical differentiation between palmar psoriasis and chronic hand eczema may sometimes be a diagnostic challenge; in such cases histopathological analysis helps to differentiate the two conditions. In the present study, palmar psoriasis and chronic hand eczema were investigated using dermoscopy and the significance of specific dermoscopic features was assessed in order to improve their non-invasive differentiation. Ten patients with biopsy-proven palmar psoriasis and 11 patients with biopsy-proven chronic hand eczema were included in the study. We found that the presence of diffuse white scales was significant in palmar psoriasis whereas the presence of yellowish scales, brownish-orange dots/globules and yellowish-orange crusts was significant in chronic hand eczema. © 2015 Japanese Dermatological Association.

The limited efficacy of topical tacrolimus may result from insufficient frequency of application or amount applied in eczema patients. To investigate the frequency of application and amount of use of topical tacrolimus in patients with various types of eczema. The frequency of application and the applied amount of topical tacrolimus were assessed over two weeks. A total of 200 eczema patients completed this study. The average number of applications per day was 1.75 ± 0.53, despite instructions to apply the topical tacrolimus twice daily. With respect to the frequency of application, 147 (73.5%) and 122 (61.0%) of patients followed the prescription in the first and second weeks, respectively. The average amount applied per 2% of total body surface area (TBSA) was 0.54 ± 0.52 g. Only 53 (26.5%) patients applied between 80 and 120% of expected amount of topical tacrolimus. The frequency of application was self-reported, possibly resulting in limited accuracy. Korean patients with eczema tend to apply topical tacrolimus less frequently and in inappropriate amounts. Clear instructions regarding both the frequency and amount of application are needed to improve the therapeutic outcome with treatment with topical tacrolimus.

Hand eczema influences the quality of life. Management strategies include the use of moisturizers. In the present study the time to relapse of eczema during treatment with a barrier-strengthening moisturizer (5% urea) was compared with no treatment (no medical or non-medicated preparations) in 53 randomized patients with successfully treated hand eczema. The median time to relapse was 20 days in the moisturizer group compared with 2 days in the no treatment group (p = 0.04). Eczema relapsed in 90% of the patients within 26 weeks. No difference in severity was noted between the groups at relapse. Dermatology Life Quality Index (DLQI) increased significantly in both groups; from 4.7 to 7.1 in the moisturizer group and from 4.1 to 7.8 in the no treatment group (p < 0.01) at the time of relapse. Hence, the application of moisturizers seems to prolong the disease-free interval in patients with controlled hand eczema. Whether the data is applic-able to moisturizers without barrier-strengthening properties remains to be elucidated.

Eczema is one of the most common chronic inflammatory skin diseases, affecting about 20% of children. The pathogenic mechanisms of eczema are still not fully understood, and current treatment of moderate-severe eczema is often difficult. Recently, it has been suggested that Vitamin D plays a key role in this disease, even if mechanisms are only partially known. The purpose of our study was to assess the 25-Hydroxyvitamin D serum levels in a pediatric population suffering from chronic eczema (IgE-mediated and non-IgE-mediated), and to correlate these phenotypes with the SCORAD severity and selected clinical and biological parameters. Moreover, we aimed to evaluate whether a supplementation of Vitamin D3 could affect the same clinical and laboratory parameters. 89 children with chronic eczema were enrolled in the study. Severity of eczema was assessed with the SCORAD index. Past and present history was taken, and patients were divided into two groups according to the state of sensitization. According to a randomization schedule, the enrolled children were assigned to the following groups: supplementation group, which received a daily oral Vitamin D3 supplementation (2000 IUs) for 3 months; control group which received no supplementation. Vitamin D concentrations in patients with moderate and severe eczema were not statistically different from Vitamin D concentration detected in the serum of patients with mild eczema. Furthermore, we did not find any correlation between Vitamin D levels, total IgEs and SCORAD index, both in the Sensitized and in the Not-Sensitized group. The Vitamin D3 supplementation did not influence the SCORAD severity or the total IgEs concentration. To our knowledge, our study is the first one that shows no correlation between serum levels of Vitamin D, eczema severity and IgE sensitization in a pediatric population suffering from chronic eczema.

To assess the properties of a novel body wash containing the mild surfactant glycinate. Biochemical and clinical assays. Research laboratories and clinical sites in the United States and Canada. Women 18 to 65 years of age (cleansing efficacy); male and female subjects 26 to 63 years of age with mild or moderate dryness and erythema (leg-controlled application test); subjects 5 to 65 years of age with mild-to-moderate eczema (eczema compatibility); and women 18 to 64 years of age (home use). Assessments across studies included colorimetric dye exclusion to assess skin damage potential (corneosurfametry), efficacy of cosmetic product removal from skin, change from baseline in visual dryness, change from baseline in Eczema Area and Severity Index, and self-perceived eczema attributes and self-reported product preference. The glycinate-based cleanser demonstrated mildness to skin components when evaluated in a corneosurfametry assay. Short-term use under exaggerated wash conditions in subjects with dryness scores <3 and erythema scores <2 (both on a 0-6 scale) indicated an initial reduction in visual dryness. In subjects with eczema, normal use resulted in significant improvements (p<0.05) at Week 4 compared with baseline in skin dryness (change from baseline = -0.73), rash (-0.56), itch (-0.927), tightness (-0.585), and all eczema (-0.756). The glycinate-based body wash removed 56 percent of a long-lasting cosmetic foundation from skin compared with less than 30 percent removed by two competitive products tested. The glycinate-based body wash was preferred over a competitive mild cleansing product overall. The patented glycinate-containing body wash demonstrated better product mildness and patient-preferred attributes and clinical benefits.

Novel specific therapies for psoriasis and eczema have been developed, and they mark a new era in the treatment of these complex inflammatory skin diseases. However, within their broad clinical spectrum, psoriasis and eczema phenotypes overlap making an accurate diagnosis impossible in special cases, not to speak about predicting the clinical outcome of an individual patient. Here, we present a novel robust molecular classifier (MC) consisting of NOS2 and CCL27 gene that diagnosed psoriasis and eczema with a sensitivity and specificity of >95% in a cohort of 129 patients suffering from (i) classical forms; (ii) subtypes; and (iii) clinically and histologically indistinct variants of psoriasis and eczema. NOS2 and CCL27 correlated with clinical and histological hallmarks of psoriasis and eczema in a mutually antagonistic way, thus highlighting their biological relevance. In line with this, the MC could be transferred to the level of immunofluorescence stainings for iNOS and CCL27 protein on paraffin-embedded sections, where patients were diagnosed with sensitivity and specificity >88%. Our MC proved superiority over current gold standard methods to distinguish psoriasis and eczema and may therefore build the basis for molecular diagnosis of chronic inflammatory skin diseases required to establish personalized medicine in the field. © 2016 John Wiley & Sons A/S.

The purpose of this case report is to describe the use of acupuncture and a gluten-free diet (GFD) for urticaria and severe eczema in a patient with undiagnosed dermatitis herpetiformis and atypical or extraintestinal celiac disease. A 48-year-old woman presented with intense urticaria, eczema, worsening heartburn, chronic constipation, headaches, and an intense feeling of heat for 4 months. Results of punch biopsies of the skin lesions and laboratory tests were inconclusive. After the acupuncture sessions reported here ended, human leukocyte antigen blood typing revealed celiac disease and dermatitis herpetiformis-associated human leukocyte antigen DQ-8. Results of an endoscopy and colonoscopy were negative. The patient received 3 acupuncture treatments a week for 12 weeks. The patient's symptoms began in March 2008. She began using topical and oral steroids and felt that her symptoms were not responding. Acupuncture began in July 2008. At the end of the first 12 treatments, during which she was using topical and oral steroids, the urticaria and constipation resolved completely; and she had temporary relief from the heartburn. It is thought that the urticaria and constipation resolved because of the acupuncture as that was the only change. At the end of the second 12 treatments, during which time she had started Optifast, a GFD, the heartburn, headache, and eczema resolved. At the end of the third 12 treatments, all her symptoms remained resolved. Steroid treatment was discontinued after the first 12 treatments. Acupuncture and diet changes appeared to provide relief from the urticaria and eczema of dermatitis herpetiformis beyond that obtained by traditional treatment of a GFD alone.

There were 5834 participants with complete data on parental social class at birth, childhood cognitive ability tests scores at 11 years, educational qualifications at 33 years, the Big Five-Factor personality traits, occupational levels and eczema (measured at age 50 years). Results showed that eczema in childhood, educational achievement and occupational levels were significantly associated with the occurrence of reported eczema in adulthood. Emotionally Stable people (non-neurotic) were less likely to have eczema, but those with high Agreeableness and Openness more likely to have eczema. Childhood cognitive ability was significantly and positively associated with eczema in adulthood.

Background Atopic dermatitis is a prevalent health problem in the world. Allergic sensitization is an important risk factor, but the roles of other factors, inherent in tropic region, are unknown. Objective A cohort study was designed in a tropical city to investigate molecular and environmental risk factors for eczema, considering as particular features perennial exposure to mites, poor living conditions and others tropical characteristics. Methods 433 patients were included at baseline and biological samples were collected during 24 months of follow-up. Clinical information was collected using questionnaires (SCORAD, DLQI and a subjective scale) during each clinical assessment. Results The prevalence of atopic eczema was 93%, with similar frequency between children and adults; parents history of eczema and polysensitization to mites, dogs, cats, cockroaches and birds, were risk factors for severe and persistent eczema and allergic comorbidities. Food sensitization was present in 16% of patients but food-induced allergies were scarce. Psychiatric, dental and ocular disorders were the most frequent non-allergic comorbidities. Study limitations selection bias. Conclusion We presented a tropical cohort of patients with eczema and we identified some risk factors for severe and persistent dermatitis. Some patterns of sensitization were associated with severe eczema and respiratory symptoms, and the natural history of "atopic march" is different to that described in some industrialized countries. The collection of biological samples will contribute to the understanding of the gene/environment interactions leading to allergy inception and evolution. PMID:28538875

Haemodialysis exposes patients to many potentially sensitizing allergens. The primary objective of this study was to evaluate the prevalence of delayed hypersensitivity in a population of haemodialysis patients. Secondary objectives were to identify the possible risk factors for contact sensitization and to propose a series of skin tests adapted to haemodialysis patients. A prospective monocentric study was carried out in a nonselected population of haemodialysis patients. For each patient, medical history of atopy and allergic contact dermatitis, ongoing treatments (including topical ones), presence of eczema at the site of vascular access for haemodialysis were recorded. Allergological investigation included delayed hypersensitivity tests (European Environmental and Contact Dermatitis Research Group battery, tests GERDA, additional list and a battery of antiseptics and other dialysis-specific allergens) and latex skin prick test. Seventy-five patients (41 men, 34 women, mean age of 65 years old), with a mean 3.8 years under dialysis, were included. Nineteen patients (25%) had at least one positive skin test and 13 (17%) a positive patch test to at least one allergen relative to dialysis process including eight tests to lidocaine-prilocaine cream and three to povidone-iodine. Tests results seemed clinically relevant since nine patients had localized pruritus at the fistula site and six patients active eczema around it. Contact sensitizations are frequent in haemodialysis patients and are linked to vascular access conditioning especially the use of lidocaine-prilocaine cream. Designing a specific test battery could help to diagnose the potential allergens and subsequently to give advice to avoid contact with sensitizing agents.

Public health nurses report on effects of fresh human milk as treatment for conjunctivitis, rhinitis and atopic eczema (AE), the latter being highly prevalent in early childhood. Emollients and topical corticosteroids are first line treatment of AE. As many caregivers have steroid phobia, alternative treatment options for mild AE are of interest. The aim of this small pilot study was to assess the potential effects and risks of applying fresh human milk locally on eczema spots in children with AE. This was a split body, controlled, randomized and physician blinded pilot study, of children with AE with two similar contralateral eczema spots having a mother breastfeeding the child or a sibling. Fresh expressed milk and emollient was applied on the intervention spot and emollient alone on the control area, three times a day for four weeks. The severity and area of the eczema spots was evaluated weekly, and samples from milk and the spots were analysed weekly with respect to bacterial colonisation. Of nine patients included, six completed the study. Mean age at inclusion was 18.5 months. The spots examined were localized on the arms, legs or cheeks. The spots were similar in severity, but differed in area. In one patient the eczema ceased after inclusion. In four patients both control and intervention areas increased during the intervention. The relative change in eczema area compared to baseline showed less increase in the intervention spots in two patients, whereas the opposite was observed in three. In four children Staphylococcus aureus was found in their eczema once or more. In three of the 28 human milk samples, Staphylococcus aureus, alfa haemolytic streptococci or coagulase negative staphylococci were detected. Staphylococcus aureus was found once both in human milk and in the eczema spots, no clinical signs of infection were however observed. No secondary infection due to milk application was detected. In this small pilot study, no effect was found on eczema spots treated with topical application of fresh human milk. (ClinicalTrials.gov Identifier, NCT02381028 ).

Topical corticosteroids (CSs) are the mainstay of treatment for eczema but CS phobia and fears are prevalent and influence therapeutic efficacy. To quantify if CS acceptability and fear affect patients' quality-of-life (QoL). Patients with eczema managed in the pediatric dermatology outpatient clinic of a university hospital were surveyed. Nottingham Eczema Severity Score (NESS) for severity, Children's Dermatology Life Quality Index (CDLQI) for QoL, CS fear, acceptability and reported frequency of CS use were measured with quantified questions. CS fears were prevalent among parents and caregivers of patients with eczema. Fifty-eight percent of parents reported general acceptability of CS as being very good or good, and many applied CS to their child regularly every week. However, >40% of parents reported CS fear "always" or "often", 41% reported that they "always" or "often" apply CS only when eczema got worse, 57% would discuss CS fear with their doctors, 30% would request CS-sparing medications and 14% "always" or "often" use traditional Chinese herbal medicine. Fears were predominantly interpersonal and less often iatrogenic in nature. Skin problems were the most concerned side effects of CS. CS acceptability, frequency of CS usage, CS fear and usage of alternative medications were independent domains in eczema management: CS fears correlated with CDLQI; CS usage frequency correlated with NESS and negatively with parental education; and CS acceptability correlated with parental education. Ordinal logistic regressions showed worse QoL was associated with more CS fear (odds ratio: 1.092 [95% CI: 1.023-1.165], p = 0.008). The extent of CS fears is independent of CS acceptability, but correlates with patients' QoL. Desensitization of parental CS fears should be integral part of eczema education and therapeutics in order to improve therapeutic efficacy and patients' QoL.

The evidence for systemic treatments for severe childhood eczema is limited and largely based on extrapolation of data from adult studies. Current therapies are often immunosuppressant and may be associated with both short- and long-term side effects. There is increasing in vitro and murine-model evidence for the role of IgE in the immunopathogenesis of atopic eczema. The aim of the study is to assess whether anti-IgE treatment (omalizumab) improves eczema, compared to placebo. The Atopic Dermatitis Anti-IgE Paediatric Trial (ADAPT) is a randomised, double-blind, placebo-controlled study assessing the role of anti-IgE in the management of severe paediatric eczema. Children with severe atopic eczema, with an objective SCORing Atopic Dermatitis (SCORAD) score of over 40 will be recruited. These children are candidates for systemic therapy, have failed systemic therapy or have experienced side effects from systemic therapy. Sixty-two patients aged between 4 and 19 years will receive anti-IgE for 6 months. The primary outcome measure will be the validated eczema score, the objective SCORAD at 24 weeks. This study has 90% power to detect a 33% relative reduction in SCORAD between active and placebo groups, with 5% significance. IgE may have a role to play in eczema, particularly in childhood. This forms the basis for the hypothesis that anti-IgE may be an effective treatment in this patient population. This will be the largest study to evaluate the efficacy of anti-IgE (omalizumab) versus placebo in children with severe eczema. The findings will help to clarify the role of anti-IgE as a potential treatment option in patients with severe childhood eczema. European Clinical Trials Database (EudraCT) Number: 2010-020841-29 .

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. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Population attributable risks from serum IgE and dust miteallergen concentrations and environmental chemicals for eczema are unclear. Therefore, it was aimed to examine serum IgE and allergen concentrations and environmental chemicals for eczema in adults and to calculate population attributable risks in a national and population-based setting. Data retrieved from the National Health and Nutrition Examination Survey, 2005-2006, was analyzed. Information on demographics and self-reported ever eczema was obtained by household interview. Bloods and urines (sub-sample) were also collected during the interview. Adults aged 20-85 were included. Statistical analyses were using chi-square test, t test, survey-weighted logistic regression modeling, and population attributable risk (PAR) estimation. Of all the included American adults (n = 4979), 310 (6.2%) reported ever eczema. Moreover, more eczema cases were observed in female adults but fewer cases in people born in Mexico. There were no significant associations observed between commonly known biomarkers (including vitamin D) and eczema or between dust mite allergens and eczema. Serum D. Farinae (PAR 1.0%), D. Pteronyssinus (PAR 1.1%), cat (PAR 1.8%), dog (PAR 1.6%), and muse (PAR 3.2%) IgE antibodies were associated with eczema. Adults with ever eczema were found to have higher levels of urinary trimethylarsine oxide concentrations (PAR 7.0%) but not other speciated arsenic concentrations. There were no clear associations between other environmental chemicals including heavy metals, phthalates, phenols, parabens, pesticides, nitrate, perchlorate, polycyclic hydrocarbons and eczema as well. Elimination of environmental risks might help delay or stop eczema up to 7% in the adult population.

Varicella infection is not associated with increasing prevalence of eczema: a U.S. population-based study.

Chickenpox infection early in childhood has previously been shown to protect against the development of childhood eczema in line with the hygiene hypothesis. In 1995, the American Academy of Pediatrics recommended routine vaccination against varicella zoster virus in the United States. Subsequently, rates of chickenpox infection have dramatically decreased in childhood. We sought to understand the impact of declining rates of chickenpox infection on the prevalence of eczema. We analysed data from 207 007 children in the 1997-2013 National Health Interview Survey. One-year prevalence of eczema and 'ever had' history of chickenpox were analysed. Associations between chickenpox infection and eczema were tested using survey-weighted logistic regression. The impact of chickenpox on trends of eczema prevalence was tested using survey logistic regression and generalized linear models. Children with a history of chickenpox compared with those without chickenpox had a lower prevalence [survey-weighted logistic regression (95% confidence interval, CI)] of eczema [8·8% (8·5-9·0%) vs. 10·6% (10·4-10·8%)]. In pooled multivariate models controlling for age, sex, race/ethnicity, household income, highest level of household education, insurance coverage, U.S. birthplace and family size, eczema was inversely associated with chickenpox [adjusted odds ratio (95% CI), 0·90 (0·86-0·94), P < 0·001]. The prevalence of eczema significantly increased over time (Tukey post-hoc test, P < 0·001 for comparisons of survey years 2001-13 vs. 1997-2000, 2008-13 vs. 2001-04 and 2008-13 vs. 2005-07). In multivariate generalized linear models, the odds of eczema was not associated with chickenpox in 2001-13 (P ≥ 0·06). These findings suggest that lower rates of chickenpox infection secondary to widespread vaccination against varicella zoster virus are not contributing to higher rates of childhood eczema in the U.S. © 2015 British Association of Dermatologists.

Dyshidrotic hand eczema is a common condition, which can be resistant to various treatments. Although a number of etiologic factors are involved in the pathogenesis of dyshidrotic eczema, hyperhidrosis is assumed to play a significant role. Oxybutynin is an alternative treatment for hyperhidrosis. We present the cases of two patients suffering from hyperhidrosis and dyshidrotic eczema, who were treated with oxybutynin with impressive results. © 2014 Wiley Periodicals, Inc.

[Atopic eczema: psychophysiological reactivity with standardized stressors].

PubMed

Münzel, K; Schandry, R

1990-11-01

In 18 atopic eczema patients with active symptomatology and 15 control subjects a comparison of reactivity to psychological stressors was made. The physiological measures were heart rate, peripheral vasomotor response, skin resistance level, spontaneous fluctuations of the skin resistance, and forearm skin temperature. In addition, self-ratings of subjective state, situational anxiety, and social anxiety were assessed. Mental arithmetic performed undisturbed and in distracting conditions, and anticipation of the latter and of having to speak in public served as stressors. The results show higher reaction values of the eczema patients for heart rate, peripheral vasomotor response, fluctuations of skin resistance and subjective tension. A subgroup of patients with extreme skin irritation (itching) reacted with an elevation of skin temperature, in contrast to control subjects and patients with less marked itching, in whom skin temperature dropped slightly. The results suggest that atopic eczema may have a psychophysiological component.

Ever since its inception a couple of centuries ago, hand dermatitis/eczema has been in the reckoning. Idiosyncrasies continued to loom large thereafter, till it acquired its appropriate position. Dermatitis/eczema are synonymous, often used to indicate a polymorphic pattern of the inflammation of the skin, characterized by pruritus, erythema and vesiculation. A spectrum delineated into acute sub-acute and chronic dermatitis of the hands. Pompholyx, recurrent focal palmer peeling, ring, wear and tear and fingertip eczema, apron, discoid eczema, chronic acral dermatitis, gut and patchy papulosquamous eczema are its clinical variants. Occupational dermatitis/eczema may be contributory. Etiological definitions are clinched by detailed history of exogenous and endogenous factors. However, scientific confirmation of the entity is through patch testing by using available antigens.

Eczematous external otitis is a chronic inflammatory disease and often difficult to treat. Our objective was to investigate the clinical effect and in vitro antibacterial potential of medical honey eardrops as treatment of eczematous external otitis. In a prospective study, 15 patients diagnosed with recurrent eczematous external otitis were treated with medical honey eardrops for 2 weeks. The following clinical outcomes were evaluated: visual analog scale of ear complaints, score of eczema, and eradication of bacterial infection. Furthermore, the antibacterial effect of honey eardrops against different bacterial strains was tested in vitro. Treatment resulted in less discomfort and itching and decreased signs of eczema, with high patient satisfaction and without adverse reactions. Honey eardrops showed a strong in vitro inhibitory activity against all tested strains but did not eradicate Staphylococcus aureus infection in vivo. The results of this preliminary study indicate a possible role of honey eardrops in eczematous ear disease.

It has remained unclear whether genetic background of patients with atopic eczema (AE) alone is identical to that of patients with both AE and atopic respiratory disease. We aimed to assess whether there is a genetic difference between these two groups of AE patients. We determined the genotype with regard to an allelic polymorphism in the gene for mast cell chymase (MCC; a serine protease secreted from mast cells) in 169 AE patients. MCC genotype was significantly associated with pure AE patients who did not have a predisposition to atopic respiratory disease and whose serum IgE concentration was < 500 IU/mL. The distribution of MCC genotypes also differed significantly between the latter patients and those AE patients with bronchial asthma and a serum IgE concentration of > 2000 IU/mL. These results suggest that pure AE is associated with genetic variants of MCC, and that the genetic basis of pure AE differs from that of AE associated with atopic asthma.

Dietary restrictions are common among patients with eczema, and such practice may lead to diminished bone mineral density. This study investigated dietary intake and bone mineral density in Hong Kong Chinese children with eczema. This cross-sectional and observational study was conducted in a university-affiliated teaching hospital in Hong Kong. Chinese children aged below 18 years with physician-diagnosed eczema were recruited from our paediatric allergy and dermatology clinics over a 6-month period in 2012. Subjects with stable asthma and/or allergic rhinitis who were free of eczema and food allergy as well as non-allergic children were recruited from attendants at our out-patient clinics as a reference group. Intake of various foods and nutrients was recorded using a food frequency questionnaire that was analysed using Foodworks Professional software. Bone mineral density at the radius and the tibia was measured by quantitative ultrasound bone sonometry, and urinary cross-linked telopeptides were quantified by immunoassay and corrected for creatinine level. Overall, 114 children with eczema and 60 other children as reference group were recruited. Eczema severity of the patients was classified according to the objective SCORing Atopic Dermatitis score. Males had a higher daily energy intake than females (median, 7570 vs 6736 kJ; P=0.035), but intake of any single food item or nutrient did not differ between them. Compared with the reference group, children with eczema had a higher intake of soybeans and miscellaneous dairy products and lower intake of eggs, beef, and shellfish. Children with eczema also consumed less vitamin D, calcium, and iron. The mean (standard deviation) bone mineral density Z-score of children with eczema and those in the reference group were 0.52 (0.90) and 0.55 (1.12) over the radius (P=0.889), and 0.02 (1.03) and -0.01 (1.13) over the tibia (P=0.886), respectively. Urine telopeptide levels were similar between the groups. Calcium intake was associated with bone mineral density Z-score among children with eczema. Dietary restrictions are common among Chinese children with eczema in Hong Kong, who have a lower calcium, vitamin D, and iron intake. Nonetheless, such practice is not associated with changes to bone mineral density or bone resorptive biomarker.

Hand eczema is often a chronic, multifactorial disease. It is usually related to occupational or routine household activities. Exact etiology of the disease is difficult to determine. It may become severe enough and disabling to many of patients in course of time. An estimated 2-10% of population is likely to develop hand eczema at some point of time during life. It appears to be the most common occupational skin disease, comprising 9-35% of all occupational diseases and up to 80% or more of all occupational contact dermatitis. So, it becomes important to find the exact etiology and classification of the disease and to use the appropriate preventive and treatment measures. Despite its importance in the dermatological practice, very few Indian studies have been done till date to investigate the epidemiological trends, etiology, and treatment options for hand eczema. In this review, we tried to find the etiology, epidemiology, and available treatment modalities for chronic hand eczema patients. PMID:24891648

The lack of standardized nomenclature for atopic dermatitis (AD) creates challenges for scientific communication, patient education, and advocacy. We sought to determine the relative popularity of the terms eczema, AD, and atopic eczema (AE) using global search engine volumes. A retrospective analysis of average monthly search volumes from 2014 to 2016 of Google, Bing/Yahoo, and Baidu was performed for eczema, AD, and AE in English and 37 other languages. Google Trends was used to determine the relative search popularity of each term from 2006 to 2016 in English and the top foreign languages, German, Turkish, Russian, and Japanese. Overall, eczema accounted for 1.5 million monthly searches (84%) compared with 247 000 searches for AD (14%) and 44 000 searches for AE (2%). For English language, eczema accounted for 93% of searches compared with 6% for AD and 1% for AE. Search popularity for eczema increased from 2006 to 2016 but remained stable for AD and AE. Given the ambiguity of the term eczema, we recommend the universal use of the next most popular term, AD.

Background: Hand eczema is a common disease seen in dermatological practice comprising of a spectrum ranging from mild disease to a severe distressing and chronic course with a negative impact on the quality of life. Aim: To assess the impact of hand eczema severity on quality of life. Materials and Methods: Patients with hand eczema were enrolled in a prospective study. Disease severity was assessed by hand eczema severity index (HECSI) score and quality of life by dermatology life quality index (DLQI) questionnaire. Results: Forty-six patients participated of which 22 (47.8%) were males and 24 (52.2%) females. The commonest age group affected among men and women was 50-59 years (31.8%) and 40-49 years (41.7%) respectively. History of atopy was found in 23.9% and 63% had persistent disease. In 28 (60.9%), the trigger was washing soaps and detergents of which 21 (87.5%) were housewives. Of those employed, 27.7% reported loss of work days. The mean HECSI score was 14.46 (S.D = 20.98) and mean DLQI score was 9.54 (S.D = 5.62). Gender, age, occupation and duration of disease did not significantly affect the quality of life or disease severity. Increased episodes of eczema (>4 episodes/year) showed a statistically significant correlation with DLQI (P value = 0.021). There was no significant correlation between HECSI score and DLQI in this study. Conclusion: Majority of the patients with hand eczema had a significant impairment of their quality of life. The impairment of quality of life in this study was mainly dependent on increased frequency of the eruptions and not on hand eczema severity. PMID:23741665

Enhancement of allergic skin wheal responses in patients with atopic eczema/dermatitis syndrome by playing video games or by a frequently ringing mobile phone.

Kimata, H

Playing video games causes physical and psychological stress, including increased heart rate and blood pressure and aggression-related feelings. Use of mobile phones is very popular in Japan, and frequent ringing is a common and intrusive part of Japanese life. Atopic eczema/dermatitis syndrome is often exacerbated by stress. Stress increases serum IgE levels, skews cytokine pattern towards Th2 type, enhances allergen-induced skin wheal responses, and triggers mast cell degranulation via substance P, vasoactive intestinal peptide and nerve growth factor. (1). In the video game study, normal subjects (n = 25), patients with allergic rhinitis (n = 25) or atopic eczema/dermatitis syndrome (n = 25) played a video game (STREET FIGHTER II) for 2 h. Before and after the study, allergen-induced wheal responses, plasma levels of substance P, vasoactive intestinal peptide and nerve growth factor, and in vitro production of total IgE, antihouse dust mite IgE and cytokines were measured. (2). In the mobile phone study, normal subjects (n = 27), patients with allergic rhinitis (n = 27) or atopic eczema/dermatitis syndrome (n = 27) were exposed to 30 incidences of ringing mobile phones during 30 min. Before and after the study, allergen-induced wheal responses, plasma levels of substance P, vasoactive intestinal peptide and nerve growth factor were measured. Playing video games had no effect on the normal subjects or the patients with allergic rhinitis. In contrast, playing video games significantly enhanced allergen-induced skin wheal responses and increased plasma levels of substance P, vasoactive intestinal peptide and nerve growth factors in the patients with atopic eczema/dermatitis syndrome. Moreover, playing video games enhanced in vitro production of total IgE and anti-house dust mite IgE with concomitant increased production of IL-4, IL-10 and IL-13 and decreased production of IFN-gamma and IL-12 in the patients with atopic eczema/dermatitis syndrome. However, exposure to frequently ringing mobile phones significantly enhanced allergen-induced skin wheal responses, plasma levels of substance P, vasoactive intestinal peptide and nerve growth factors in the patients with atopic eczema/dermatitis syndrome, but not in the normal subjects or the patients with allergic rhinitis. Playing video games enhanced allergic responses with a concomitant increased release of substance P, vasoactive intestinal peptide and nerve growth factor, and skewing of the cytokine pattern toward Th2 type in the patients with atopic eczema/dermatitis syndrome. In addition, exposure to frequently ringing mobile phones also enhanced allergic responses with a concomitant increased release of substance P, vasoactive intestinal peptide and nerve growth factor Collectively, high technology causes stress, which in turn may aggravate symptoms of atopic eczema/dermatitis syndrome.

1994-08-01

Hand eczema is one of the most common dermatological disorders. Although it is a general term referring to eczematous dermatitis of the hands, it actually covers a wide range of diseases. The classification of hand eczema is controversial even now, as definitions of individual diseases have not yet been established. It is well-known that exogenous factors, such as chemicals or water, are associated with the occurrence of hand eczema. In this study, we focused on endogenous factors, especially personal or family history of atopy as a causative factor in hand eczema. According to exogenous and endogenous factors, we classified hand eczema into three types: atopic dermatitis, contact dermatitis and dysidrosis. This classification is useful because it makes the definition of each disease clear. Skin-humidity and sebum measurement are simple and rapid methods of determining personal atopy, skin condition and the effect of treatment on hand eczema patients.

A discussion on the reasons educational interventions about eczema, by nurses, are successful, with the subsequent development of a theoretical framework to guide nurses to become effective patient educators. Effective child and parent education is the key to successful self-management of eczema. When diagnosed, children and parents should learn to understand the condition through clear explanations, seeing treatment demonstrations and have ongoing support to learn practical skills to control eczema. Dermatology nurses provide these services, but no one has proposed a framework of the concepts underpinning their successful eczema educational interventions. A discussion paper. A literature search of online databases was undertaken utilizing terms 'eczema OR atopic dermatitis', 'education', 'parent', 'nurs*', 'framework', 'knowledge', motivation', in Scopus, CINAHL, Web of Science, Medline and Pubmed. Limits were English language and 2003-2013. The framework can inform discussion on child and parent education, provide a scaffold for future research and guide non-specialist nurses, internationally, in providing consistent patient education about eczema. Founded on an understanding of knowledge, the framework utilizes essential elements of cognitive psychology and social cognitive theory leading to successful self-management of eczema. This framework may prove useful as a basis for future research in child and parent education, globally, in the healthcare community. A framework has been created to help nurses understand the essential elements of the learning processes at the foundation of effective child and parent education. The framework serves to explain the improved outcomes reported in previous nurse-led eczema educational interventions. © 2014 The Authors.

Deodorants are one of the most marketed types of cosmetics and are frequently reported as a cause of dermatitis, particularly among fragrance-sensitive persons. The aim of this study was to investigate the ability of deodorants, which had previously caused axillary dermatitis in fragrance-mix-sensitive eczema patients, to provoke reactions on repeated open application tests on the upper arm and in the axillae, and to relate the findings to the content of fragrance-mix constituents in those deodorants. 14 eczema patients performed a 7-day use test with 1 or 2 deodorants that had caused a rash within the last 12 months. 2 applications per day were made in the axilla and simultaneously on a 25 cm2 area on the upper arm. A total of 20 deodorants were tested among the 14 patients. Afterwards, the deodorants were subjected to quantitative chemical analysis identifying constituents of the fragrance mix. 12/20 (60%) deodorants elicited eczema on use testing in the axilla. 8/12 deodorants were positive in the axilla on day (D) 7 and 4 both in the axilla and on the upper arm. 2 of the 4 developed a reaction in the axilla before it developed on the upper arm. Chemical analysis revealed that 18/19 deodorants contained between 1 and 6 of the fragrance-mix constituents, on average 3 being found. The mean concentration of fragrance-mix constituents was generally higher in the deodorants causing a positive use test, as compared with those giving a negative reaction, indicating that the differences between the deodorants in terms of elicitation potential were more related to quantitative aspects of allergen content than of a qualitative nature. It is recommended that deodorants are tested in the axilla in the case of a negative use test on the upper arm and a strong clinical suspicion.

Abstract Little is known about the classification and bacterial infection in outpatients with eczema and dermatitis in China. To investigate the prevalence of eczema and dermatitis in outpatients of dermatology clinics in China, examine classification and proportion of common types of dermatitis and the possible bacterial infection, and analyze the possible related factors. Outpatients with eczema or dermatitis from 39 tertiary hospitals of 15 provinces in mainland China from July 1 to September 30, 2014, were enrolled in this cross-sectional and multicenter study. Among 9393 enrolled outpatients, 636 patients (6.7%) were excluded because of incomplete information. The leading subtypes of dermatitis were unclassified eczema (35.5%), atopic dermatitis (13.4%), irritant dermatitis (9.2%), and widespread eczema (8.7%). Total bacterial infection rate was 52.3%, with widespread eczema, stasis dermatitis, and atopic dermatitis being the leading three (65.7%, 61.8%, and 61.4%, respectively). Clinically very likely bacterial infection has a significant positive correlation with disease duration, history of allergic disease, history of flexion dermatitis, and severe itching. Atopic dermatitis has become a common subtype of dermatitis in China. Secondary bacterial infection is common in all patients with dermatitis, and more attentions should be paid on this issue in other type of dermatitis apart from atopic dermatitis. PMID:28858126

Occupational hand eczema (OHE) is associated with impaired health-related quality of life (QoL) and mental distress. Interdisciplinary inpatient rehabilitation measures in the framework of tertiary individual prevention (TIP) offered by the German employers' liability insurance associations include dermatological treatment, education and psychological interventions. To investigate the effects of interdisciplinary inpatient rehabilitation in the framework of TIP on mental health in patients with severe OHE and the relationships between recovery of OHE and improvement of mental health and QoL. A total of 122 patients participated in the study. A test battery consisting of the German versions of the Hospital Anxiety and Depression Scale (HADS-D), the Dermatology Life Quality Index (DLQI), the Short Form Health Survey-36 (SF-36) and the Trier Inventory for the Assessment of Chronic Stress (TICS) was applied at the time of admission (T1) and 3 weeks after dismissal (T2). Severity of hand eczema was assessed with the Osnabrueck Hand Eczema Severity Index (OHSI). All parameters improved significantly from T1 to T2. A relationship was established between the improvement of QoL and recovery of OHE, while there was no such relationship between the improvement of mental distress and improvement of OHE. Nonresponders had significantly more cumulative days of sickness at T1. Our data underscore the importance of psychological interventions in addition to dermatological treatment in the framework of prevention measures for OHE. These measures should be applied at an early stage of OHE prior to the occurrence of sick leave. © 2015 European Academy of Dermatology and Venereology.

Background The innate immune pathway is important in the pathogenesis of asthma and eczema. However, only a few variants in these genes have been associated with either disease. We investigate the association between polymorphisms of genes in the innate immune pathway with childhood asthma and eczema. In addition, we compare individual associations with those discovered using a multivariate approach. Methods Using a novel method, case control based association testing (C2BAT), 569 single nucleotide polymorphisms (SNPs) in 44 innate immune genes were tested for association with asthma and eczema in children from the Boston Home Allergens and Asthma Study and the Connecticut Childhood Asthma Study. The screening algorithm was used to identify the top SNPs associated with asthma and eczema. We next investigated the interaction of innate immune variants with asthma and eczema risk using Bayesian networks. Results After correction for multiple comparisons, 7 SNPs in 6 genes (CARD25, TGFB1, LY96, ACAA1, DEFB1, and IFNG) were associated with asthma (adjusted p-value<0.02), while 5 SNPs in 3 different genes (CD80, STAT4, and IRAKI) were significantly associated with eczema (adjusted p-value < 0.02). None of these SNPs were associated with both asthma and eczema. Bayesian network analysis identified 4 SNPs that were predictive of asthma and 10 SNPs that predicted eczema. Of the genes identified using Bayesian networks, only CD80 was associated with eczema in the single-SNP study. Using novel methodology that allows for screening and replication in the same population, we have identified associations of innate immune genes with asthma and eczema. Bayesian network analysis suggests that additional SNPs influence disease susceptibility via SNP interactions. Conclusion Our findings suggest that innate immune genes contribute to the pathogenesis of asthma and eczema, and that these diseases likely have different genetic determinants. PMID:22192168

The use of nonstandardized and inadequately validated outcome measures in atopic eczema trials is a major obstacle to practising evidence-based dermatology. The Harmonising Outcome Measures for Eczema (HOME) initiative is an international multiprofessional group dedicated to atopic eczema outcomes research. In June 2011, the HOME initiative conducted a consensus study involving 43 individuals from 10 countries, representing different stakeholders (patients, clinicians, methodologists, pharmaceutical industry) to determine core outcome domains for atopic eczema trials, to define quality criteria for atopic eczema outcome measures and to prioritize topics for atopic eczema outcomes research. Delegates were given evidence-based information, followed by structured group discussion and anonymous consensus voting. Consensus was achieved to include clinical signs, symptoms, long-term control of flares and quality of life into the core set of outcome domains for atopic eczema trials. The HOME initiative strongly recommends including and reporting these core outcome domains as primary or secondary endpoints in all future atopic eczema trials. Measures of these core outcome domains need to be valid, sensitive to change and feasible. Prioritized topics of the HOME initiative are the identification/development of the most appropriate instruments for the four core outcome domains. HOME is open to anyone with an interest in atopic eczema outcomes research. © 2012 John Wiley & Sons A/S.

The frequent clinical observation that the course of atopic eczema, a skin disease involving a disturbed cutaneous barrier function, is influenced by climate and weather motivated us to analyse these relationships biometrically. In the Swiss high-mountain area of Davos the intensity of itching experienced by patients with atopic eczema was evaluated and compared to 15 single meteorological variables recorded daily during an entire 7-year observation period. By means of univariate analyses and multiple regressions, itch intensity was found to be correlated with some meteorological variables. A clear-cut inverse correlation exists with air temperature (coefficient of correlation: -0.235, P<0.001), but the effects of water vapour pressure, air pressure and hours of sunshine are less pronounced. The results show that itching in atopic eczema is significantly dependent on meteorological conditions. The data suggest that, in patients with atopic eczema, a certain range of thermo-hygric atmospheric conditions with a balance of heat and water loss on the skin surface is essential for the skin to feel comfortable.

The exact etiology and pathogenesis of eczema are not yet fully understood, although different factors are considered as pathogenic mechanisms in the development of eczema. Our study was designed to determine extent of serum lipid peroxidation, antioxidants, macro minerals and trace elements in patients with eczema, and thereby, find any pathophysiological correlation. The study was conducted as a case-control study with 65 eczema patients as cases and 65 normal healthy individuals as controls. Lipid peroxidation was assessed by measuring the serum level of malondialdehyde (MDA). Antioxidants- vitamin A and E concentration was determined by RP-HPLC method whereas vitamin C was evaluated for serum ascorbic acid by UV spectrophotometric method. Serum macro minerals (Na, K, Ca) and trace elements (Zn, Fe) were determined by Atomic Absorption Spectroscopy (AAS). This study found significantly higher level of MDA (p < 0.001) and lower level of antioxidants (p < 0.05) in patients in comparison to the control subjects. Analysis of serum macro minerals (Na, K and Ca) and trace elements (Zn, Fe) found that the mean values of Na, K, Ca, Zn and Fe were 2771.60 ± 75.64, 66.33 ± 3.03, 48.41 ± 2.50, 0.30 ± 0.02 and 0.29 ± 0.009 mg/L for the patient group and 3284.81 ± 34.51, 162.18 ± 3.72, 87.66 ± 2.10, 0.75 ± 0.06 and 0.87 ± 0.06 mg/L for the control group, accordingly. There was a significant difference for all the minerals between the patients and controls (p < 0.001). This study suggests a strong association between the pathogenesis of eczema with the elevated level of MDA and depleted level of antioxidants, macro minerals, and trace elements.

Background Null mutations within the filaggrin gene (FLG) cause ichthyosis vulgaris and are associated with atopic eczema. However, the dermatological features of filaggrin haploinsufficiency have not been clearly defined. Objectives This study investigated the genotype–phenotype association between detailed skin phenotype and FLG genotype data in a population-based cohort of children. Methods Children (n= 792) aged 7–9 years were examined by a dermatologist. Features of ichthyosis vulgaris, atopic eczema and xerosis were recorded and eczema severity graded using the Three Item Severity score. Each child was genotyped for the six most prevalent FLG null mutations (R501X, 2282del4, R2447X, S3247X, 3702delG, 3673delC). Fisher’s exact test was used to compare genotype frequencies in phenotype groups; logistic regression analysis was used to estimate odds ratios and penetrance of the FLG null genotype and a permutation test performed to investigate eczema severity in different genotype groups. Results Ten children in this cohort had ichthyosis vulgaris, of whom five had mild–moderate eczema. The penetrance of FLG null mutations with respect to flexural eczema was 55·6% in individuals with two mutations, 16·3% in individuals with one mutation and 14·2% in wild-type individuals. Summating skin features known to be associated with FLG null mutations (ichthyosis, keratosis pilaris, palmar hyperlinearity and flexural eczema) showed a penetrance of 100% in children with two FLG mutations, 87·8% in children with one FLG mutation and 46·5% in wild-type individuals (P< 0·0001, Fisher exact test). FLG null mutations were associated with more severe eczema (P= 0·0042) but the mean difference was only 1–2 points in severity score. Three distinct patterns of palmar hyperlinearity were observed and these are reported for the first time. Conclusions Filaggrin haploinsufficiency appears to be highly penetrant when all relevant skin features are included in the analysis. FLG null mutations are associated with more severe eczema, but the effect size is small in a population setting. PMID:19681860

Titanium has been considered to be a non-allergenic material. However, several studies have reported cases of metal allergy caused by titanium-containing materials. We describe a 69-year-old male for whom significant pathologic findings around dental implants had never been observed. He exhibited allergic symptoms (eczema) after orthopedic surgery. The titanium screws used in the orthopedic surgery that he underwent were removed 1 year later, but the eczema remained. After removal of dental implants, the eczema disappeared completely. Titanium is used not only for medical applications such as plastic surgery and/or dental implants, but also for paints, white pigments, photocatalysts, and various types of everyday goods. Most of the usage of titanium is in the form of titanium dioxide. This rapid expansion of titanium-containing products has increased percutaneous and permucosal exposure of titanium to the population. In general, allergic risk of titanium material is smaller than that of other metal materials. However, we suggest that pre-implant patients should be asked about a history of hypersensitivity reactions to metals, and patch testing should be recommended to patients who have experienced such reactions.

It has been suggested that lifestyle factors such as smoking, overweight and stress may influence the prevalence and severity of hand eczema. To investigate the association between lifestyle factors and hand eczema severity in a cohort of patients with work-related hand eczema. Individuals with work-related hand eczema notified in the period between June 2012 and November 2013 were included in this questionnaire-based cross-sectional study. Participants responded to a questionnaire including questions on lifestyle factors, as well as a photographic guide for assessment of severity of hand eczema and questions on quality of life. A total of 773 individuals (546 women and 227 men) responded to the questionnaire and were included in the study. A strong association was found between tobacco smoking and hand eczema severity (p = 0.003), whereas no significant association was found for body weight and stress. Other factors linked to severe eczema were male sex and older age (p = 0.04 and p = 0.01, respectively), and wet work (p = 0.08). The data from the present study strongly support an association between smoking and hand eczema severity. However, owing to the cross-sectional design of the study, no conclusion on causation can be drawn. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Core beliefs and psychological distress in patients with psoriasis and atopic eczema attending secondary care: the role of schemas in chronic skin disease.

The role of ingrained cognitive and emotional patterns (schemas) in patients with psoriasis and eczema has not previously been investigated. High levels of psychiatric morbidity and psychological distress observed in these populations suggest the presence of maladaptive schemas and therefore a possible target for future successful psychological intervention. To investigate the presence of early maladaptive schemas (EMS) in patients with psoriasis and eczema and to explore their links with psychological distress. A sample of 185 adults (psoriasis n = 55, atopic eczema n = 54, chronic disease control n = 23, normal control n = 53) completed validated, self-administered questionnaires. Differences were found between dermatology patients and control groups. Patients with psoriasis differed on seven EMS from the normal control group: emotional deprivation (P = 0·011), social isolation (P < 0·001), defectiveness (P < 0·001), failure (P < 0·001), vulnerability to harm (P < 0·001), subjugation (P = 0·009) and emotional inhibition (P = 0·002). They differed from the chronic disease group on vulnerability to harm (P = 0·002) only. Patients with eczema differed from the normal control group on eight EMS: emotional deprivation (P < 0·001), social isolation (P < 0·001), defectiveness (P < 0·001), failure (P < 0·001), dependence (P = 0·010), vulnerability to harm (P = 0·002), subjugation (P = 0·006) and insufficient self-control (P = 0·010). EMS were strongly positively related to psychological distress experienced by dermatology patients. Hierarchical regressions demonstrated two schemas, vulnerability to harm (P < 0·001) and defectiveness (P = 0·029), to be predictive of anxiety, and social isolation (P = 0·012) and vulnerability to harm (P = 0·018) to be predictive of depression, irrespective of age and years of coping for dermatology patients. The findings have important theoretical and clinical implications for psychological management of patients with psoriasis and eczema. Treatment protocols may benefit by targeting schemas. Further studies are needed to investigate the benefits of schema-focused therapy in patients with skin disease. © 2012 The Authors. BJD © 2012 British Association of Dermatologists.

As global population of the elderly continues to rise, a critical need to provide it with health services, including dermatology, will be significant, especially in developing countries like Tanzania. To adequately meet their dermatologic needs, knowledge of local patterns of skin conditions is vital. This study was aimed to describe the spectrum of skin diseases among elderly patients attending skin clinic at the Regional Dermatology Training Centre (RDTC) in Northern Tanzania. A descriptive hospital based cross-sectional study was conducted between January 2013 and April 2013 at RDTC and included all patients aged 55 years and above who consented to be examined. Diagnoses were clinical, diagnostic tests being done only when necessary. Ethical clearance to conduct the study was granted. A total of 142 patients, age ranges 55-99 years, median age of 67.5 years were seen. Eczemas were the leading disease group (43.7%), with unclassified eczemas (33.9%) predominating. Papulosquamous disorders (15.4%) were second with psoriasis (50%) being the leading disease. Infections (11.3% with fungal infections the leading group representing 5.6% of all diseases), tumours (9.8%: Kaposi's sarcoma 4.2%), vascular disorders 9.1% (lymphedema 4.9%), autoimmune disorders 7.7% (connective tissue diseases 4.9%), vitiligo 4.2%, nutritional diseases 2.1% (pellagra 0.7%), urticaria 0.7% and drug reactions 0.7%. Eczemas are the most common group of disorders among elderly patients presenting at RDTC.

This article is a report of the fourth meeting of the Harmonising Outcome Measures for Eczema (HOME) initiative held in Malmö, Sweden on 23-24 April 2015 (HOME IV). The aim of the meeting was to achieve consensus over the preferred outcome instruments for measuring patient-reported symptoms and quality of life for the HOME core outcome set for atopic eczema (AE). Following presentations, which included data from systematic reviews, consensus discussions were held in a mixture of whole group and small group discussions. Small groups were allocated a priori to ensure representation of different stakeholders and countries. Decisions were voted on using electronic keypads. For the patient-reported symptoms, the group agreed by vote that itch, sleep loss, dryness, redness/inflamed skin and irritated skin were all considered essential aspects of AE symptoms. Many instruments for capturing patient-reported symptoms were discussed [including the Patient-Oriented SCOring Atopic Dermatitis index, Patient-Oriented Eczema Measure (POEM), Self-Administered Eczema Area and Severity Index, Itch Severity Scale, Atopic Dermatitis Quickscore and the Nottingham Eczema Severity Score] and, by consensus, POEM was selected as the preferred instrument to measure patient-reported symptoms. Further work is needed to determine the reliability and measurement error of POEM. Further work is also required to establish the importance of pain/soreness and the importance of collecting information regarding the intensity of symptoms in addition to their frequency. Much of the discussion on quality of life concerned the Dermatology Life Quality Index and Quality of Life Index for Atopic Dermatitis; however, consensus on a preferred instrument for measuring this domain could not be reached. In summary, POEM is recommended as the HOME core outcome instrument for measuring AE symptoms. © 2016 The Authors.

Atopic dermatitis is a common, chronic, debilitating disease. Poor adherence to treatment is the most important preventable contributor to adverse outcomes. Thus, improving adherence can improve patient outcomes. Text message reminders with embedded condition-specific information have been shown to improve pediatric immunization adherence but have not been assessed in atopic dermatitis. The objective was to assess the effect of daily text messages on Eczema Area Severity Index scores and caregiver knowledge of atopic dermatitis. In this pilot randomized controlled trial, caregivers of children with atopic dermatitis enrolled during their initial appointment with a pediatric dermatologist and randomized 1:1 to standard care or daily text messages with patient education material and treatment reminders. Participants completed a multiple-choice atopic dermatitis knowledge quiz at initial and follow-up visits, and Eczema Area Severity Index scores were assessed. Forty-two patients enrolled, and 30 completed the study: 16 standard care group, 14 text message group. There was no significant difference in Eczema Area Severity Index score between the standard care and text message groups at follow-up, with mean decreases in Eczema Area Severity Index score of 53% and 58%, respectively. Mean score on follow-up atopic dermatitis knowledge quiz was significantly higher in the text message group (84% correct) than in the standard care group (75% correct) (P = .04). This pilot study did not demonstrate a difference in Eczema Area Severity Index scores with text message reminders. The significantly higher follow-up atopic dermatitis quiz score in the text message group indicates that participants read and retained information from text messages. Limitations include small sample size and short duration of follow-up. © 2018 Wiley Periodicals, Inc.

To compare with a control group the frequency of psychiatric disorders and severity of psychiatric symptoms in preschool children with atopic eczema. The study included children between the ages of 3-5 who were diagnosed to have atopic eczema. The parents of the children with atopic eczema were interviewed in person and were asked to fill in "The Early Childhood Inventory-4" form. This form assesses the psychiatric disorders and symptoms severity in children between the ages of 3-5. The atopic eczema group included 80 patients (38 male, 42 female) with a mean age of 48.4 ± 15.7 months and the control group included 74 patients (41 male, 33 female) with a mean age of 49.9 ± 15.19 months. It was established that 68.8% of the group with atopic eczema received at least one psychiatric diagnosis. Between the psychiatric disorders, ADHD (Odds ratio: 2.57, 95% CI: 1.049-6.298, p=0.035), enuresis and encopresis (Odds ratio: 2.39, 95% CI: 1.121-5.097, p=0.022) and attachment disorder (Odds ratio: 2.03, 95% CI: 1.046-3.953, p=0.035) were found to be significantly higher when compared with the healthy control group. When the groups were compared in terms of psychiatric symptom severity scores calculated by using ECI-4, ADHD severity (p=0.043), conduct disorder severity (p=0.001), anxiety disorders severity (p<0.001), eating disorders severity (p=0.011) and tic disorder severity (p=0.01) were found to be higher in the atopic eczema group. Psychiatric illnesses are frequent in preschool children with atopic eczema. Copyright © 2015 SEICAP. Published by Elsevier Espana. All rights reserved.

Objective To assess parental stress levels of mothers of children less than 6 years old with eczema and compare these levels with those reported for other chronic childhood illnesses. Methods Mothers were recruited from hospital‐based out‐patient clinics (55%) or while their child was an in‐patient (45%) for management of eczema. Maternal stress was measured utilising the Parenting Stress Index‐Long Form (PSI) in 33 mothers. The severity of the eczema at the time of interview was documented by the Eczema Area and Severity Index (EASI) score and the Investigators' Global Assessment (IGA) score. Results The children with eczema had a mean age of 2.8 years. Mothers of children aged 5 years or less with eczema exhibited significantly higher total stress scores (mean PSI 259.6, 95% CI 244.9 to 274.3) as compared to mothers of normal children (PSI 222.8, 95% CI 221.4 to 224.2) and children with other chronic disorders such as insulin‐dependent diabetes (PSI 218.1, 95% CI 204.7 to 231.6) and profound deafness (PSI 221.7, 95% CI 206.4 to 237.0). Stress scores in the parental domain (138.2, 95% CI 128.9 to 147.6) did not differ significantly from the scores of parents of children with severe disabilities such as those requiring home enteral feeding (135.2, 95% CI 129.3 to 141.1) and those with Rett syndrome (132.8, 95% CI 125.0 to 140.6). Conclusions Moderate to severe childhood eczema should be regarded as a significant illness in which maternal stress is equivalent to that associated with the care of children with severe developmental and physical problems.

2016-01-01

Background Atopic dermatitis (or eczema) is a chronic inflammatory disorder associated with sleep disturbances and quality-of-life impairment. Sleep disturbances have been shown to cause headaches in childhood. However, an association between eczema and headaches is not well established. Objectives We sought to determine whether childhood eczema is associated with increased headaches and whether such association is related to fatigue or sleep disturbance. Methods We analyzed data from 401,002 children and adolescents in 19 US population-based cross-sectional studies from the National Survey of Children’s Health 2003/2004 and 2007/2008 and the National Health Interview Survey 1997–2013. Results In multivariate models controlling for age, sex, race/ethnicity, household income, highest level of education in the family, insurance coverage, number of persons in the household, birthplace in the United States, ever history of asthma, hay fever, and food allergy, eczema was found to be associated with headaches in 14 of 19 studies. In a pooled analysis of all 19 studies, children with eczema compared with those without eczema had a significantly higher prevalence (10.7% [95% CI, 10.3% to 11.0%] vs 5.4% [95% CI, 5.3% to 5.5%]) and odds (1.52 [95% CI, 1.45–1.59]) of headaches. Mild (1.79 [95% CI, 1.07–2.98]) and severe (2.72 [95% CI, 1.33–5.57]) eczema were associated with significantly higher odds of headaches. In particular, eczema associated with atopy, fatigue, excessive daytime sleepiness, insomnia, and only 0 to 3 nights of sufficient sleep had even higher odds of headache than eczema alone. Conclusions Eczema is associated with increased headaches in childhood, particularly in patients with severe disease accompanied by atopy, fatigue, and sleep disturbances. PMID:26329510

Dental workers are considered to have a high risk of developing occupational hand eczema. To estimate the prevalence of work-related hand eczema and associated risk factors in dental workers in Japan. A self-administered questionnaire was sent by mail to all dental clinics of Kumamoto City, Japan. In addition, patch testing with 24 dentistry-related allergens was offered. In total, 46.4% of dental workers (n = 528: response 31.4%, based on 97 clinics) reported a lifetime history of chronic hand eczema. The 1-year prevalence was 36.2%. According to logistic regression analysis, the most important risk factors for the 1-year prevalence were a personal history of atopic dermatitis [odds ratio (OR) 4.7, 95% confidence interval (CI): 2.2-8.8], asthma and/or allergic rhinitis (OR 2.0, 95%CI: 1.3-3.0), dry skin (OR 1.7, 95%CI: 1.1-2.7), shorter duration of work (OR 2.0, 95%CI: 1.2-3.5 for up to 10 years versus >20 years), and washing hands >10 times per day (OR 1.6, 95%CI: 1.0-2.5). Fifty-four workers were patch tested. Rubber chemicals and acrylates were the most frequent occupationally relevant contact allergens. Dental workers in Japan have a high prevalence of hand eczema. Health education to prevent hand eczema and more frequent patch testing are needed. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

This study investigated the perspective of international patients on individual symptoms of atopic dermatitis (eczema) in determining treatment response. A questionnaire was developed to evaluate the importance of symptoms from the patient's perspective. Patients were asked: "How important are these features in deciding whether or not a treatment is working?", and rated symptoms on a 5-point Likert scale. Patients were approached via Harmonising Outcome Measures for Eczema (HOME) collaborators and self-selected to take part in the on-line survey. Patients from 34 countries (n = 1,111) completed the survey; of these, 423 (38.3%) were parents of children with eczema. Nine items were rated as being "quite important" or "very important" by more than 80% of the respondents: itch, pain/soreness, skin feels hot or inflamed, bleeding, involvement of visible or sensitive body sites, cracks, sleep difficulties, amount of body affected, and weeping/oozing. These results may be of use in determining the face validity of scales from a cross-cultural patients' perspective.

The systematic support of parents of children with eczema is essential to their effective management; however, we have few models of support. This study examines the rationale, evidence base and development of a large-scale, structured, theory-based, nurse-led intervention, the 'Eczema Education Programme' (EEP), for parents of children with eczema. To outline development of the EEP, model of delivery, determine its feasibility and evaluate this based on service access and parental satisfaction data. Parent-child dyads meeting EEP referral criteria were recruited and demographic information recorded. A questionnaire survey of parental satisfaction was conducted 4 weeks post EEP; parental focus groups at 6 weeks provided comparative qualitative data. Descriptive statistics were derived from the questionnaire data using Predictive Analytics Software (PASW); content analysis was applied to focus group data. A total of 356 parents attended the EEP during the evaluation period. Service access was achieved for those in a challenging population. Both survey data (n = 146 parents, 57%) and focus group data (n = 21) revealed a significant level of parental satisfaction with the programme. It was feasible to provide the EEP as an adjunct to normal clinical care on a large scale, achieving a high level of patient/parent satisfaction and access within an urban area of multiple deprivation and high mobility. The intervention is transferable and the results are generalizable to other ethnically diverse child eczema populations within metropolitan areas in Britain. A multicentre RCT is required to test the effectiveness of this intervention on a larger scale. © 2013 European Academy of Dermatology and Venereology.

The Harmonising Outcome Measures for Eczema (HOME) initiative has defined four core outcome domains for a core outcome set (COS) to be measured in all atopic eczema (AE) trials to ensure cross-trial comparison: clinical signs, symptoms, quality of life and long-term control. The aim of this paper is to report on the consensus process that was used to select the core instrument to consistently assess symptoms in all future AE trials. Following the HOME roadmap, two systematic reviews were performed which identified three instruments that had sufficient evidence of validity, reliability and feasibility to be considered for the final COS. At the fourth international HOME meeting, there was broad consensus among all stakeholders that the Patient-Oriented Eczema Measure (POEM) should be used as the core instrument (87·5% agreed, 9·4% unsure, 3·1% disagreed). All relevant stakeholders are encouraged to use POEM as the chosen instrument to measure the core domain of symptoms in all future AE clinical trials. Other instruments of interest can be used in addition to POEM. © 2016 British Association of Dermatologists.

Atopic eczema affects 5-10% of the Spanish paediatric population, and has increased in frequency over the last few decades, probably due to changes in the environment and lifestyle. Phase II of the ISAAC (International Study of Asthma and Allergies in Childhood) uses a standardised methodology to establish the prevalence of allergic disorders and factors linked to them in each centre. To assess the prevalence and severity of atopic eczema, and to establish factors linked to atopic eczema in 10-11 year-old school children in the city of Almeria (South-East coast of Spain). An ecological study was carried out as part of ISAAC II, using homologated questionnaires and allergic tests in 1143 schoolchildren. Statistic association was assessed by means of chi(2) test, and then logistic regression analysis was performed with the most significant variables from the univariant analysis. The prevalence of atopic eczema was 11.4%. The risk factors found in the multiple logistic regression analysis were: personal antecedents of severe asthma (OR 19 CI 95% 1.35-266) and severe rhinitis (OR 7.7 CI 95% 1.79-33), fungi in bedroom during the first year of life (OR 4.2 CI 95% 1.17-15.1) and atopic eczema in one parent (OR 5.2 CI 95% 2.69-10.1). The prevalence of atopic eczema is similar to that found in other studies within ISAAC Phase I. The most important risk factors for atopic eczema are family and personal history of other atopic diseases and the presence of fungi in the home. Copyright 2009 SEICAP. Published by Elsevier Espana.

Background Association of genetic-variants in the FADS1-FADS2-gene-cluster with fatty-acid-composition in blood of adult-populations is well established. We analyze this genetic-association in two children-cohort-studies. In addition, the association between variants in the FADS-gene-cluster and blood-fatty-acid-composition with eczema was studied. Methods and Principal Findings Data of two population-based-birth-cohorts in the Netherlands and Germany (KOALA, LISA) were pooled (n = 879) and analyzed by (logistic) regression regarding the mutual influence of single-nucleotide-polymorphisms (SNPs) in the FADS-gene-cluster (rs174545, rs174546, rs174556, rs174561, rs3834458), on polyunsaturated fatty acids (PUFA) in blood and parent-reported eczema until the age of 2 years. All SNPs were highly significantly associated with all PUFAs except for alpha-linolenic-acid and eicosapentaenoic-acid, also after correction for multiple-testing. All tested SNPs showed associations with eczema in the LISA-study, but not in the KOALA-study. None of the PUFAs was significantly associated with eczema neither in the pooled nor in the analyses stratified by study-cohort. Conclusions and Significance PUFA-composition in young children's blood is under strong control of the FADS-gene-cluster. Inconsistent results were found for a link between these genetic-variants with eczema. PUFA in blood was not associated with eczema. Thus the hypothesis of an inflammatory-link between PUFA and eczema by the metabolic-pathway of LC-PUFAs as precursors for inflammatory prostaglandins and leukotrienes could not be confirmed by these data.

Chronic hand eczema is a debilitating dermatological condition with significant economic, social, and functional impacts. To date, conventional treatments such as topical corticosteroids, phototherapy, and systemic immunosuppressants have yielded disappointing results, owing to either a lack of efficacy or significant adverse events. Oral alitretinoin (9-cis-retinoic acid) is a unique panagonist retinoid with immunomodulatory and anti-inflammatory activity that has emerged as a novel treatment for chronic hand eczema. Several large-scale clinical studies have demonstrated oral alitretinoin's high efficacy rate of 28% to 89%, its safe tolerability profile, and its positive impact on quality of life, validating it as a therapeutic option for patients with severe chronic hand eczema refractory to standard treatment.

Kathon is an anti-microbial agent that is used as a preservative in cosmetics and bodily hygiene products. At the recommended levels of usage Kathon is innocuous and has a recognised efficacy. Nevertheless, following reappearance of contact allergic eczemas due to cosmetics and bodily hygiene products different authors have reported increase in sensitisation to it. We have met the same problems in the Service de Dermatology++ of the Hospital Sainte Marguerite at Marseille and we wished to make a deeper examination of the question and to ascertain whether the current cosmetics contained Kathon CG. For this we have developed a technique of liquid chromatography and tested 44 creams. Eight contained Kathon CG, of which 2 were responsible for contact eczema in patients.

Farmers are at high risk of occupational skin diseases which may start already during vocational training. This study was aimed at identification of risk factors for work-related skin diseases among vocational students of agriculture. The study involved 440 students (245 males, 195 females aged 17-21 years) in 11 vocational schools which were at least 100 km from each other. The protocol included a physician-managed questionnaire and medical examination, skin prick tests, patch tests, total IgE and Phadiatop. Logistic regression model was used for the identification of relevant risk factors. Work-related dermatoses were diagnosed in 29 study participants (6.6%, 95%CI: 4.3-8.9%): eczema in 22, urticaria in 14, and co-existence of both in 7 students. Significant risk factors for work-related eczema were: history of respiratory allergy (OR=10.10; p<0.001), history of eczema (itchy rash) provoked by wet work and detergents before entering the school (OR=5.85; p<0.001), as well as history of contact dermatitis to metals, rubber or cosmetics prior to inscription (OR=2.84; p=0.016), and family history of any skin disease (OR=2.99; p=0.013). Significant risk factors for work-related urticaria were: history of allergic rhinitis and asthma prior to inscription (OR=7.29; p=0.006), positive skin prick tests to work place allergens (OR=4.65; p=0.002) and to environmental allergens (OR=3.79; p=0.009), and positive Phadiatop test (OR=3.61; p=0.013). Work-related skin diseases are common among vocational students of agriculture. Atopy, past history of asthma, allergic rhinitis, and eczema (either atopic, allergic or irritant) are relevant risk factors for work-related eczema and urticaria in young farmers, along with family history of any skin disease. Positive skin prick tests seem relevant, especially in the case of urticaria. Asking simple, aimed questions during health checks while enrolling students into agricultural schools would suffice to identify students at risk for work-related eczema and urticaria, giving them the chance for selecting a safer profession, and hopefully avoiding an occupational disease in the future.

To evaluate the effect of a secondary prevention programme with education on skin care and individual counselling versus treatment as usual in healthcare workers with hand eczema. Randomised, observer blinded parallel group superiority clinical trial. Three hospitals in Denmark. 255 healthcare workers with self reported hand eczema within the past year randomised centrally and stratified by profession, severity of eczema, and hospital. 123 were allocated to the intervention group and 132 to the control group. Education in skin care and individual counselling based on patch and prick testing and assessment of work and domestic related exposures. The control was treatment as usual. The primary outcome was clinical severity of disease at five month follow-up measured by scores on the hand eczema severity index. The secondary outcomes were scores on the dermatology life quality index, self evaluated severity of hand eczema, skin protective behaviours, and knowledge of hand eczema from onset to follow-up. Follow-up data were available for 247 of 255 participants (97%). At follow-up, the mean score on the hand eczema severity index was significantly lower (improved) in the intervention group than control group: difference of means, unadjusted -3.56 (95% confidence interval -4.92 to -2.14); adjusted -3.47 (-4.80 to -2.14), both P<0.001 for difference. The mean score on the dermatology life quality index was also significantly lower (improved) in the intervention group at follow-up: difference of means: unadjusted -0.78, non-parametric test P=0.003; adjusted -0.92, -1.48 to -0.37). Self evaluated severity and skin protective behaviour by hand washings and wearing of protective gloves were also statistically significantly better in the intervention group, whereas this was not the case for knowledge of hand eczema. A secondary prevention programme for hand eczema improved severity and quality of life and had a positive effect on self evaluated severity and skin protective behaviour by hand washings and wearing of protective gloves.

Introduction The aim of the study was to provide current data on the incidence of allergy to various contact allergens in patients with allergic contact eczema and the analysis of selected socio-demographic data of the patients. Material and methods The study included 1532 patients (1010 women and 522 men) treated for allergic contact dermatitis at the Department of Dermatology and Venereology and at the Dermatology Outpatient Clinic in Bialystok in 2007–2011. The assessment of selected demographic data and skin lesions was based on the MOAHFLA index, while the results of patch tests were analyzed with modified Baseline European Series consisting of 31 allergens. Results In the group of patients with eczema, 34.1% were men, and 55% of all respondents were people over 40 years of age. The occupational character of skin lesions was found in 22.5%. Most frequently (38.9%) skin lesions were localized on the hands, rarely involved legs (3.98%). Atopic dermatitis was diagnosed in 4.5% of patients. The ten most frequent allergens were: nickel sulfate (24%), cobalt chloride (15.3%), fragrance mix (8.25%), potassium dichromate (6.8%), balsam of Peru (5.5%), neomycin (4.42%), paraphenylenediamine (3.85%), Quatermium-15 (2.1%), detreomycin (1.83%) and budesonide (1.44% of tested patients). Conclusions Frequent allergy to detreomycin indicates the need of patch testing for this allergen of all examined patients with allergic contact dermatitis. The increased frequency of the nickel allergy is a worrying problem and indicates the need for education about the risk factors for nickel allergy development and the implementation of appropriate legal regulations.

Hand eczema is common and has an adverse impact on the lives of patients. There is a need for population-based surveys on the pharmacoepidemiological aspects, quality of life and impact of socioeconomic factors in hand eczema. The aim of this cross-sectional study was to investigate these factors. A questionnaire-based nationwide survey of health was performed, including questions on hand eczema, use of pharmaceuticals and socioeconomic factors. Quality of life was estimated with the generic instrument Short Form 36 (SF-36). The questionnaire was sent to 7,985 persons (age range 18-84 years), response rate 61.1% (n = 4,875). The 1-year prevalence of hand eczema in the study population was 7.5%. In this group, quality of life was lower. All dimensions of SF-36 were affected, most markedly general health and those dimensions reporting on mental health. In the group with self-reported hand eczema, 51% reported using topical pharmaceuticals. Hand eczema was more common among women (9.1%, n = 2,630) than among men (5.6%, n = 2,245) and in the age group below 65 years (8.5%, n = 3,274) compared with those aged 65 years and over (4.3%, n = 1,151). This survey clearly demonstrates the impact of hand eczema on several dimensions of life and also highlights age, gender and socioeconomic differences.

Anti-programmed cell death (PD)-1 therapy is emerging as the backbone of new standard of care immunotherapy for metastatic melanoma. Immune-related cutaneous events are observed in these patients. We sought to describe cutaneous adverse events observed in patients with metastatic melanoma on anti-PD-1 therapy. We reviewed the clinical and histologic information of all patients treated with single-agent anti-PD-1 therapy for metastatic melanoma at Westmead Hospital, Sydney, Australia, from May 2012 to February 2015. Of the 82 patients included in the study, 34 had dermatology assessments. Forty (49%) developed a form of anti-PD-1-associated cutaneous adverse events. In all, 17% developed lichenoid reactions and eczema, and 15% developed vitiligo. An estimated 25% of patients were expected to develop their first lichenoid reactions within 8.3 months, and eczema and vitiligo within 10.3 months of therapy. These adverse events tend to appear together in patients on anti-PD-1 therapy. The study was from a single center and clinical information was reviewed retrospectively in patients not referred to dermatology. Anti-PD-1 therapy is associated with the development of immune-related cutaneous events. Lichenoid reactions, eczema, and vitiligo are the 3 most prevalent lesions observed in our population. There is a tendency for lichenoid reactions and eczema to occur with vitiligo. Copyright © 2015 American Academy of Dermatology, Inc. Published by Elsevier Inc. All rights reserved.

Atopic dermatitis and hand eczema often impair the ability of people to work. Only a few studies have investigated whether individuals with loss-of-function filaggrin gene (FLG) mutations, who often have severe and early onset of dermatitis, experience occupational consequences. To investigate the personal consequences of having atopic dermatitis and/or hand eczema and FLG mutations. Adult Danes from the general population (n = 3247) and patients with atopic dermatitis and/or hand eczema (n = 496) were genotyped for common FLG mutations, and completed a questionnaire about skin symptoms and hand eczema. Socioeconomic variables, including disability pension, and information on work in risk occupations were retrieved from national registries. The reasons for granting disability pension were unknown. Disability pension was associated with hand eczema in the general population, especially among individuals with a history of atopic dermatitis. Moreover, self-reported hand eczema and atopic dermatitis were associated with particularly high risk of disability pension among FLG mutation carriers [odds ratio (OR) 4.02 and 95% confidence interval (CI): 1.15-14.11; and OR 6.01 and 95%CI: 2.37-15.34, respectively]. Furthermore, 60% of the FLG mutation carriers with atopic dermatitis who developed hand eczema had experienced symptoms before adulthood. In the general population, self-reported hand eczema and atopic dermatitis, particularly in individuals with a genetically impaired skin barrier, were associated with disability pension, suggesting that FLG mutations carriers with a history of atopic dermatitis and hand eczema could benefit from early attention with respect to choice of occupation. © 2017 John Wiley & Sons A/S.

Eczema is a common chronic or chronically relapsing, inflammatory skin disease that exerts a substantial negative impact on quality of life (QoL). The Harmonising Outcome Measures for Eczema (HOME) initiative has used a consensus-based process which identified QoL as one of the four core outcome domains to be assessed in all eczema clinical trials. A number of measurement instruments exist to measure QoL in infants, children, and adolescents with eczema, and there is a great variability in both content and quality of the instruments used. Therefore, the objective of the proposed research is to comprehensively and systematically assess the measurement properties of the existing measurement instruments that were developed and/or validated for the measurement of patient-reported QoL in infants, children, and adolescents with eczema. This study is a systematic review of the measurement properties of patient-reported measures of QoL developed and/or validated for infants, children, and adolescents with eczema. A systematic literature search will be carried out in MEDLINE via PubMed and EMBASE using a selection of relevant search terms. Eligible studies will be primary empirical studies evaluating, describing, or comparing measurement properties of QoL instruments for infants, children, and adolescents with eczema. Two reviewers will independently perform eligibility assessment and data abstraction. Evidence tables will be used to record study characteristics, instrument characteristics, measurement properties, and interpretability. The adequacy of the measurement properties will be assessed using predefined criteria. The COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) checklist will be used to evaluate the methodological quality of included studies. A best evidence synthesis will be undertaken if more than one study has examined a particular measurement property. The proposed systematic review will yield a comprehensive assessment of measurement properties of existing QoL instruments in infants, children, and adolescents with eczema. The results will serve as a basis to recommend a QoL measurement instrument for infants, one for children, and one for adolescents for use in future clinical trials. PROSPERO CRD42015023483.

Background Immune specific genes as well as genes regulating the formation of skin barrier are major determinants for eczema manifestation. There is a debate as to whether allergic sensitization and filaggrin gene (FLG) variants lead to eczema or FLG variants and eczema increase the risk of allergic sensitization. To investigate the time-order between eczema and allergic sensitization with respect to FLG variants, data from a large prospective study covering infancy to late adolescence were analyzed. Methodology/Principal Findings Repeated measurements of eczema and allergic sensitization (documented by skin prick tests) at ages 1, 2, 4, 10, and 18 years were ascertained in the Isle of Wight birth cohort (n = 1,456). Three transition periods were analyzed: age 1-or-2 to 4, 4 to 10, and 10 to 18 years. FLG variants were genotyped in 1,150 participants. Over the three transition periods, in temporal sequence analyses of initially eczema-free participants, the combined effect of FLG variants and allergic sensitization showed a 2.92-fold (95% CI: 1.47–5.77) increased risk ratio (RR) of eczema in subsequent examinations. This overall risk was more pronounced at a younger age (transition period 1-or-2 to 4, RR = 6.47, 95% CI: 1.96–21.33). In contrast, FLG variants in combination with eczema showed a weaker, but significant, risk ratio for subsequent allergic sensitization only up to 10 years of age. Conclusions/Significance Taking the time order into account, this prospective study demonstrates for the first time, that a combination of FLG variants and allergic sensitization increased the risk of eczema in subsequent years. Also FLG variants interacted with eczema and increased the risk of subsequent allergic sensitization, which, was limited to the younger age. Hence, early restoration of defective skin barrier could prevent allergic sensitization and subsequently reduce the risk of eczema development. PMID:22403702

Overview of Reviews The prevention of eczema in infants and children: an overview of Cochrane and non-Cochrane reviews

Background Eczema is the most common inflammatory skin disease of childhood, characterized by an itchy red rash that usually involves the face and skin folds. There is currently no curative treatment for eczema, so the reduction of eczema incidence through disease prevention is a desirable goal. Potential interventions for preventing eczema include exclusive breastfeeding, hydrolysed protein formulas and soy formulas when bottle feeding, maternal antigen avoidance, omega oil supplementation, prebiotics and probiotics. Objectives This overview of reviews aims to present the current body of data from Cochrane and non-Cochrane reviews to provide the most up-to-date evidence on the efficacy and safety of interventions to prevent eczema in infants and children at different risk levels for developing allergic disease. Methods Our pool of Cochrane and non-Cochrane reviews came from the 2010 United Kingdom National Health Service (NHS) Evidence Skin Disorders Annual Evidence Updates Mapping Exercise on Atopic Eczema. This group used a comprehensive search strategy last conducted in August 2010 to identify all systematic reviews on eczema prevention. We identified all reviews that met our pre-specified inclusion criteria, and data were extracted, analysed, compiled into tables and synthesized using quantitative and qualitative methods. Main results Seven systematic reviews containing 39 relevant trials with 11 897 participants were included in this overview. Overall, there was no clear evidence that any of the main interventions reviewed reduced eczema incidence. In subgroup analyses of infants at high risk of allergic disease, an observational study found that exclusive breastfeeding for at least six months compared with introduction of solids at three to six months decreased the incidence of eczema by 60% (risk ratio (RR): 0.40; 95% confidence interval (CI): 0.21, 0.78), and a randomized controlled trial found that prebiotics compared with no prebiotics decreased incidence by 58% (RR: 0.42; 95% CI: 0.21, 0.84). However, each of these findings was based on the results of a single small trial, and no intervention reduced eczema incidence beyond the first two years of life. Although we pre-specified incidence of atopic eczema (i.e. eczema associated with immunoglobulin E (IgE) sensitization) as a primary outcome, data on whether participants diagnosed with eczema were truly atopic were largely lacking from systematic reviews. Similarly, data on atopy, measured using skin prick tests or specific IgE tests to allergens, were not reported in many reviews. No interventions were found to decrease atopy when reported. Adverse events data were generally lacking, but data from a trial of probiotics versus no probiotics showed significantly more spitting up in the first one (RR: 1.88; 95% CI: 1.03, 3.45) and two (RR: 1.69; 95% CI: 1.02, 2.80) months of life, but no overall increase in risk of gastrointestinal symptoms in the first year. Authors’ conclusions Although there is currently no clear evidence showing that any of the interventions examined in this overview prevent eczema in participants not selected for risk of allergic disease, there is some evidence that exclusive breastfeeding for at least six months and prebiotics might reduce eczema incidence in high-risk participants. However, these conclusions are based on limited evidence with methodological shortcomings. Future research on prevention of eczema is needed and should examine different types of hydrolysed formulas, prebiotics and probiotics, as well as enhancement of the skin barrier and other novel approaches in infants at different risk levels for developing allergic disease.

Recent studies of cutaneous nociception in atopic and non-atopic subjects.

Heyer, G R; Hornstein, O P

Itching reflects a distinct quality of cutaneous nociception elicited by chemical or other stimuli to neuronal receptors at the superficial layers of the skin and muco-cutaneous orifices. Although recent experimental studies of the conduction and perception of itch have yielded deeper insight into the physiology of this sensory quality, little is known about the neuromechanisms involved in pruritus accompanying many inflammatory skin diseases, in particular, in atopic eczema. Previous case-control studies of our research group with patients suffering from atopic eczema (AE) revealed significantly diminished itch perception after iontophoretic application of different doses of histamine as well as substance P (i.c. injected). Further experiments using acetylcholine (ACh, i.c.) clearly demonstrated that ACh elicits pruritus instead of pain in patients with AE. The first part of the present review deals with the results of our most recent case-control studies on histamine-induced itch perception in atopics devoid of eczema as well as in patients with urticaria or psoriasis compared to atopics with or without manifest eczema. We demonstrated that both focal itch and perifocal alloknesis (i.e., itch elicited by a slight mechanical, otherwise non-itching stimulus) were significantly reduced in eczema-free atopics yet were normal in non-atopics suffering from urticaria or psoriasis. In further studies using ACh i.c. injected into the uninvolved skin of patients with AE, lichen ruber, psoriasis, type IV contact eczema, or non-specific nummular eczema (n = 10/each group), all the atopics and 6/10 psoriatics felt itch instead of burning pain, but none of the others did. Different doses of vasoactive intestinal peptide (VIP) i.c. applied to the controls and the atopics with or without eczema did not markedly increase the intensity of nociceptive sensations. However, ACh induced pain in the controls, pure pruritus in the atopics with acute eczema, and a 'mixture' of pain and itch in the atopics just free from eczema. Obviously, the quality of sensations evoked by ACh and VIP depends on the inflammatory or non-inflammatory state of the atopic skin. In a placebo-controlled, double blind study on histamine-induced focal itch and alloknesis with healthy subjects (n = 15) using naltrexone (opioid receptor antagonist) and cetirizine (H1-blocking agent), naltrexone was found to significantly reduce both itching and alloknesis. Cetirizine reduced focal itch but failed to influence the alloknesis phenomenon. The wheal and flare reaction was suppressed only by cetirizine. These different effects point to a mainly CNS-based activity of naltrexone but a peripheral level effect of cetirizine. Due to long-lasting experience with group sport as a supporting adjuvant for inpatients with AE, we evaluated, by clinical, psychometric, and physiological studies, the therapeutic efficacy of controlled physical exercise in addition to otherwise equal anti-eczematous therapy for both voluntary participants and non-participants in sports by performing several case-control studies, one followed-up to 6 months after the patients' discharge from the hospital. Regular moderate exercises neither deteriorated nor impeded the recovery from AE, ameliorated the participants' scratch controlling ability and significantly their depressed emotional mood. The non-participants failed to achieve these aims. Sweating-induced itch was inhibited in almost all participants if simple skin care (clearing by warm shower, ointment) and short-term rest were used by informed patients. In conclusion, there are several indications that itching is elicited in individuals inclined to cutaneous atopy, regardless of their eczematous or just eczema-free state, by a different physiological pathway from that in non-atopic individuals. Therefore, antipruritic agents influencing the centrally altered nociception of atopics are needed and may be expected in near future. (ABSTRACT TRUNCATED)

Update on the use of alitretinoin in treating chronic hand eczema

PubMed Central

Ghasri, Pedram; Scheinfeld, Noah

2010-01-01

Chronic hand eczema is a debilitating dermatological condition with significant economic, social, and functional impacts. To date, conventional treatments such as topical corticosteroids, phototherapy, and systemic immunosuppressants have yielded disappointing results, owing to either a lack of efficacy or significant adverse events. Oral alitretinoin (9-cis-retinoic acid) is a unique panagonist retinoid with immunomodulatory and anti-inflammatory activity that has emerged as a novel treatment for chronic hand eczema. Several large-scale clinical studies have demonstrated oral alitretinoin’s high efficacy rate of 28% to 89%, its safe tolerability profile, and its positive impact on quality of life, validating it as a therapeutic option for patients with severe chronic hand eczema refractory to standard treatment.

Hand eczema has a one-year prevalence of approximately 10 % in the general Danish population. Often the disease becomes chronic with numerous implications for the individual's daily life, occupation and quality of life. However, no guidelines of self-management recommendations beyond the acute stage are given. Self-management of the disease is pivotal and involves self-monitoring of the condition, medication adherence, and preventive behaviour. Interventions best to support the individual in this ongoing process need to be developed. This paper describes the design of a randomised clinical trial to test a newly developed intervention of individual counselling versus conventional information. 300 patients consecutively referred to dermatologic treatment at two different settings are individually randomised to either the intervention programme, named 'The Healthy Skin Clinic' or to the control group. Block-wise randomisation according to setting and gender is carried out.The intervention offers a tool for self-monitoring; basic and specific individual counselling; the possibility of asynchronous communication with the intervention team; and an electronic patient dialogue forum. Primary outcome variable is objective assessment of the hand eczema severity performed at baseline prior to randomisation, and repeated at six months follow-up. Secondary outcome variables are dermatology related life quality and perceived global burden of disease. The trial aims at evaluating a newly developed guidance programme which is expected to support self-management of patients referred to dermatology treatment due to chronic hand eczema. The design of the protocol is pragmatic with blinding of neither participants nor the investigator. Thus, in the interpretation of the results, the investigator takes into account effects that may be attributed to actors of the interventions rather than the intervention per se as well of potential observer bias. Inclusion criterions are wide in order to increase transferability of the results. The trial is registered in ClinicalTrials.Gov with registration number NCT01482663.

Silverberg, Jonathan I

2016-02-01

Atopic dermatitis (or eczema) is a chronic inflammatory disorder associated with sleep disturbances and quality-of-life impairment. Sleep disturbances have been shown to cause headaches in childhood. However, an association between eczema and headaches is not well established. We sought to determine whether childhood eczema is associated with increased headaches and whether such association is related to fatigue or sleep disturbance. We analyzed data from 401,002 children and adolescents in 19 US population-based cross-sectional studies from the National Survey of Children's Health 2003/2004 and 2007/2008 and the National Health Interview Survey 1997-2013. In multivariate models controlling for age, sex, race/ethnicity, household income, highest level of education in the family, insurance coverage, number of persons in the household, birthplace in the United States, ever history of asthma, hay fever, and food allergy, eczema was found to be associated with headaches in 14 of 19 studies. In a pooled analysis of all 19 studies, children with eczema compared with those without eczema had a significantly higher prevalence (10.7% [95% CI, 10.3% to 11.0%] vs 5.4% [95% CI, 5.3% to 5.5%]) and odds (1.52 [95% CI, 1.45-1.59]) of headaches. Mild (1.79 [95% CI, 1.07-2.98]) and severe (2.72 [95% CI, 1.33-5.57]) eczema were associated with significantly higher odds of headaches. In particular, eczema associated with atopy, fatigue, excessive daytime sleepiness, insomnia, and only 0 to 3 nights of sufficient sleep had even higher odds of headache than eczema alone. Eczema is associated with increased headaches in childhood, particularly in patients with severe disease accompanied by atopy, fatigue, and sleep disturbances.

In a genome-wide association study, a common variant on chromosome 11q13.5 (rs7927894[T]) has been identified as a susceptibility locus for eczema. We aimed to analyze the effect of this risk variant on asthma and hay fever and to determine its impact on the general population level in over 9300 individuals of the prospectively evaluated Avon Longitudinal Study of Parents and Children birth cohort. We demonstrate an association of rs7927894[T] with atopic asthma and with hay fever. The largest effect sizes were found in patients with the combined phenotype atopic asthma plus eczema [odds ratio (OR) = 1.50; 95% confidence interval (CI) 1.20-1.88; P = 3.7 × 10(-4)] and hay fever plus eczema (OR = 1.37; 95% CI 1.15-1.62; P = 3.8 × 10(-4)). We replicated the effects of rs7927894[T] on eczema-associated asthma and hay fever independently in the German GENUFAD (GEnetic studies in NUclear Families with Atopic Dermatitis) study and show that they are significantly larger than the effect observed in eczema. The estimated population attributable risk fractions for eczema, eczema-associated atopic asthma or hay fever were 9.3, 24.9 and 23.5%, respectively. Finally in eczema, we found a synergistic interaction of rs7927894[T] with filaggrin gene (FLG) mutations, which are a major cause of epidermal barrier dysfunction, and replicated the interaction in the German Multicenter Allergy Study birth cohort. The synergistic effect of rs7927894[T] and FLG mutations on eczema risk as well as the association of both variants with eczema-associated atopic asthma and hay fever point to an involvement of rs7927894[T] in a functional pathway that is linked to the barrier defect.

Health-related quality of life and hand eczema--a comparison of two instruments, including factor analysis.

Hand eczema is a disease of long duration, affecting the individual and society. The purpose of this study of 100 patients (51 females and 49 males) at an occupational dermatology clinic was to investigate whether the generic questionnaire Short Form-36 (SF-36), and the dermatology-specific Dermatology Life Quality Index (DLQI) are appropriate for assessing health-related quality of life (HRQL) in patients with hand eczema, and whether gender differences in HRQL could be detected. HRQL was affected by hand eczema, measured with both SF-36 and DLQI. The SF-36 showed more impaired HRQL for females than for males, in the mental health dimension, whereas no gender-related differences were detected with the DLQI. To compare the instruments we used factor analysis, with a polychoric correlation matrix as input, thus taking the ordinal aspect of the data into account. There was a high correlation between the instruments for physical health, but lower for mental health. In this context our interpretation of the factor analysis is that the SF-36 measures mental health better than the DLQI. The SF-36 therefore appears suitable for use in future studies for measuring HRQL, and gender differences in HRQL, in persons with reported hand eczema.

Food allergy has been associated with lower weight and height in cross-sectional studies in children; however, this has not been investigated in longitudinal studies to explore growth over time, and previous studies have not accounted for coexisting eczema. The objective of this study was to examine the association of IgE-mediated food allergy and eczema with anthropometric measures at 1 and 4 years of age. In the HealthNuts population-based cohort, infants recruited at age 1 year underwent a skin prick test to egg, peanut, and sesame; those sensitized had oral food challenges. Food challenges repeated at 4 years determined food allergy persistence or resolution. Eczema was defined as parent report of eczema diagnosis. Parent-reported weight and height and child health record data were used to calculate age- and sex-adjusted percentiles from World Health Organization charts. Multivariable linear regression models were fitted to examine the effect of food allergy and eczema on weight and height controlling for potential confounders. Children with both food allergy and eczema at age 1 had lower percentiles for mean weight (51.3 vs 58.3 percentile, P = .001) and height (48.4 vs 53.4, P = .028) at age 1 compared with those with neither condition. There was no difference for children with only food allergy or eczema at age 1. By age 4, children with persistent food allergy and persistent eczema, but not those with resolved food allergy, were still shorter and lighter. Children with both food allergy and eczema were shorter and lighter throughout early childhood, with more pronounced differences in those with persistent food allergy.

Eczema and sleep and its relationship to daytime functioning in children.

2010-12-01

Chronic childhood eczema has significant morbidity characterised by physical discomfort, emotional distress, reduced child and family quality-of-life and, of particular note, disturbed sleep characterised by frequent and prolonged arousals. Sleep disturbance affects up to 60% of children with eczema, increasing to 83% during exacerbation. Even when in clinical remission, children with eczema demonstrate more sleep disturbance than healthy children. Notably, disturbed sleep in otherwise healthy children is associated with behavioural and neurocognitive deficits. Preliminary evidence suggests that disturbed sleep in children with eczema is also associated with behavioural deficits while the impact on neuropsychological functioning remains unexplored. In conclusion, a disease which affects up to 20% of children in some countries and may produce long-term behavioural and neurocognitive deficits merits further evaluation using standardised tests of sleep, behaviour and neurocognition.

Gradual increase in cutaneous pain threshold was found in healthy subjects and patients with atopic eczema during repeated hypnotic sessions with specific suggestions. This increase was less in the former than in the latter group. Repeated threshold measurements did not influence the threshold. The analgesic effect outlasted the hypnotic sessions by several months. It could be, however, suddenly reduced by appropriate hypnotic suggestion.

Eczema in the cubital fossa, which is susceptible to sweat, is frequently observed in atopic dermatitis (AD). However, there has been no direct evidence that sweating causes eczema in the cubital fossa. To investigate this issue, axon reflex-mediated sweating volume (AXR) and skin barrier function in the cubital fossa were measured in subjects with AD and in healthy volunteers, and were applied to clinical feature of the cubital fossa. AXR in the cubital fossa decreased in AD subjects; it positively correlated only with water-holding capacity in healthy subjects but not in patients with in AD. Furthermore, AD subjects with lichenoid eczema and either prurigo or papules over the cubital fossa showed extremely decreased AXR. These results suggest that decreased sweating is a major source of water in the stratum corneum, and decreased sudomotor function may be involved in both the cause and aggravation of representative atopic eczema in the cubital fossa.

Contact Eczema Caused by True Teak (Tectona Grandis)

An epidemiological study of occupational contact eczema in a furniture factory is presented. The localization, distribution, and clinical features of the skin lesions were characteristic of contact eczema caused by a sensitizing or irritating dust. True teak—Tectona grandis—was the cause of the skin condition. That teak is a fairly potent sensitizer and also contains primary irritants is fully confirmed by the present study. About half the employees who were heavily exposed to teak dust suffered from eczema and/or severe itching. Only 8% of those with slight exposure to teak dust experienced skin symptoms. Patch tests with native teak dust moistened with water were applied on 10 “controls” and 112 workers who were exposed to teak in various working procedures. Moistened teak dust produced toxic reactions in 20·5%, while native teak dust did not have primary irritant effects and was, therefore, considered to be the substance of choice for patch testing; 18·7% of the workers showed an allergic skin reaction to native teak dust. The diagnosis of allergic contact eczema was made in 12·5%, and 6·2% were considered to have latent allergy. Primary irritant (contact) eczema was considered to be present in four individuals who had experienced acute, transitory, eczematous eruptions during the hot part of the summer when they perspired freely. In these cases the patch test to native teak dust was negative. Desensitization or “hardening” was observed in four workers. In most cases the skin lesions were not severe enough to cause sickness absence. The cause of the relatively high percentage of sensitization to teak among the workers in the factory is discussed. The importance of suitable prophylactic measures is stressed. PMID:14459786

Breastfeeding is said to protect children from eczema (atopic dermatitis), but the available evidence is conflicting and subject to the influences of parental atopy and reverse causation (when mothers extended duration of breastfeeding because their children had eczema). In the prospective, population-based Leicester Respiratory Cohort study, we assessed duration of breastfeeding in children aged 1-4 years. Prevalence of eczema was determined by questionnaire surveys that were repeated until the children were 17 years old. We investigated the association between having been breastfed and current eczema using generalized estimating equations, adjusting for potential confounders, and tested for effect modification by parental atopy. We also assessed the association between having been breastfed and incident eczema at ages 2, 4, and 6 years using multivariable logistic regression. Among the 5,676 children in the study, 2,284 (40%) had never been breastfed, while 1,610 (28%), 705 (12%), and 1,077 (19%) had been breastfed for 0-3, 4-6, and >6 months, respectively. Prevalence of current eczema decreased from 36% in 1-year-olds to 18% in children aged 10-17 years. Breastfeeding was not associated with current eczema. Compared with children who had never been breastfed, the adjusted odds ratios for current eczema at any age were 1.02 (95% confidence interval 0.90-1.15) for children who had been breastfed for 0-3 months, 0.97 (0.82-1.13) for children breastfed for 4-6 months, and 0.98 (0.85-1.14) for children breastfed for >6 months. There was no strong evidence for an effect modification by parental atopy (p-value for interaction term was 0.061) and no association between having been breastfed and incident eczema later in childhood. This population-based cohort study found no evidence for protection of breastfeeding against childhood eczema at any age, from infancy through adolescence.

Background 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. Methods A systematic review of the MEDLINE, EMBASE, and LILACS (1945–2016) for the terms AD, atopic eczema (AE), and multiple other eczematous disorders. Results 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. Conclusion 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. PMID:27392131

Few food diets in the treatment of atopic eczema.

Sixty six children with severe atopic eczema were treated with highly restricted ('few food') diets followed, if they improved, by serial reintroduction of excluded foods. Twenty four patients (36%) improved considerably during the few food phase of the diet. Fifteen of these (23% of the study group) maintained this improvement on dietary treatment, of whom three abandoned the diet after periods ranging from six to 10 months, despite continued benefit, because they found the dietary restrictions too arduous. Thus 12 out of 66 children (18%) with severe eczema experienced prolonged and useful benefit from this dietary manoeuvre. Double blind food challenges performed in 10 patients failed to establish that parental identification of provoking foods is reliable. A search for historical and in vitro predictors of diet responsiveness was unsuccessful in this series. PMID:2624475

Hand eczema affects nearly 10% of the population. The condition becomes severe and chronic in 5% to 7% of cases and is refractory to topical corticosteroids in 2% to 4%. This study aimed to describe the current use of oral alitretinoin in treating Spanish national health system patients with hand eczema that is refractory to potent topical corticosteroids. Observational, descriptive, exploratory, cross-sectional study based on the retrospective analysis of records for patients with hand eczema treated with alitretinoin in the Spanish national health system. We reviewed the records for 62 patients in 13 hospitals in 5 different administrative areas (autonomous communities) of Spain. Alitretinoin was usually used at a dosage of 30mg/d. In most cases the physician judged the clinical response to be satisfactory after a single cycle. The recorded adverse effects were foreseeable and of the type reported for systemic retinoids. The dermatologists agreed that the clinical benefits achieved with alitretinoin favored adherence to treatment and an early return to work. The results show that oral alitretinoin is being used according to established recommendations and that response is good, with few adverse effects. The dermatologists agreed that the benefits favored adherence and improved the patients' health related quality of life. Copyright © 2015 AEDV. Published by Elsevier España, S.L.U.

Validation of Scratching Severity as an Objective Assessment for Itch.

Udkoff, Jeremy; Silverberg, Jonathan I

2018-05-01

There are currently no simple, standardized, objective assessments of itch for clinical trials and practice. We sought to validate and test the severity of scratching as an objective measure of itch (4-point ordinal scale ranging from 0 [not present] to 3 [very prominent] based on the observation of scratching lesions). We performed a prospective outpatient study using questionnaires and evaluations by a dermatologist in adults with atopic dermatitis (n = 261). Severity of scratching best correlated with patient-reported global atopic dermatitis severity (Kendall τ = 0.336, P < 0.0001), numeric rating scale of itch in the past 24 hours (τ = 0.266, P = 0.0010) and 3 days (τ = 0.296, P < 0.0001). Severity of scratching showed responsiveness over time. Patients experiencing improvement of scratching severity of 1 point or greater had significantly lower itch based on numeric rating scale in the past 3 days (Wilcoxon rank sum test, P = 0.0175), 5-D itch scale (P = 0.0146), and Patient-Oriented Eczema Measure scores (P = 0.0146). There was a significant decrease in scratching severity for patients experiencing itch improvement of 4 points or greater in the past 3 days on the numeric rating scale (Fisher exact test, P = 0.0026), Patient-Oriented Eczema Measure (P < 0.0001), and Dermatology Life Quality Index (P = 0.0285). Severity of scratching may be a useful endpoint in clinical trials and practice across the gamut of pruritic disorders. Future studies are needed to validate severity of scratching in other pruritic disease. Copyright © 2017 The Authors. Published by Elsevier Inc. All rights reserved.

Objective To examine risk factors for eczema at age 4 years. Study design Beginning at age one, infants of atopic parents (n=636) had annual clinical evaluations and skin prick tests (SPTs) to 15 aeroallergens, and milk and egg. Parents completed validated surveys on eczema and environmental exposures. House dust samples were evaluated for allergens and endotoxin. Eczema was defined as a parental report of scratching, and redness, “raised bumps,” or dry skin/scaling for 6 of the last 12 months. Results At age four, 90 children (16%) had eczema. Not having a dog prior to age one and being dog SPT+ at ages one, two, and/or three conferred a four-fold higher risk for eczema at age four (aOR=3.9 [1.6–9.2]; p=0.002). Among dog owners, however, dog SPT+ was not associated with significantly increased risk (aOR 1.3 [0.3–6.8]; p=0.8). Among children with cats prior to age one, cat SPT+ conferred significantly increased risk for eczema (aOR= 13.3 [3.1–57.9]; p<0.001). Among non-cat owners, cat SPT+ was not associated with increased risk (aOR=1.1 [0.5–2.7]; p=0.8). Conclusion Dog ownership significantly reduced the risk for eczema at age four among dog sensitized children, and cat ownership combined with cat sensitization significantly increased the risk.

Beginning at 1 year of age, infants of atopic parents (n = 636) had annual clinical evaluations and skin prick tests (SPTs) to 15 aeroallergens and milk and egg. Parents completed validated surveys on eczema and environmental exposures. House dust samples were evaluated for allergens and endotoxin. Eczema was defined as a parental report of scratching, and redness, "raised bumps," or dry skin/scaling for 6 of the last 12 months. At age 4 years, a total of 90 children (14%) had eczema. Not having a dog before 1 year of age and being dog SPT+ at 1, 2, or 3 years of age conferred a 4-fold higher risk for eczema at age 4 years (adjusted odds ratio [aOR] = 3.9 [1.6-9.2]; P = .002). Among dog owners, however, dog SPT+ was not associated with significantly increased risk (aOR 1.3 [0.3-6.8]; P = .8). Among children with cats before 1 year of age, cat SPT+ conferred significantly increased risk for eczema (aOR = 13.3 [3.1-57.9]; P < .001). Among non-cat owners, cat SPT+ was not associated with increased risk (aOR = 1.1 [0.5-2.7]; P = .8). Dog ownership significantly reduced the risk for eczema at age 4 years among dog-sensitized children, cat ownership combined with cat sensitization significantly increased the risk.

This study reports the findings from a user evaluation of a counselling programme for hand eczema patients in which face-to-face encounters were supplemented with user access to a new website. Patients treated for hand eczema in two different settings were included consecutively. Website utilization was examined by use of the transaction log. Comparisons were made between participants who used the website and those who did not. The patients' perspectives were explored by the use of interviews. Among potential website users (n = 140), 88 patients (63%) had an average of 5.1 site visits. At follow-up, the website users had improved more in quality of life (p = 0.014), current burden of disease (p = 0.053), and itching (p = 0.042). The website users reported more changes in habits than did the non-website users (p = 0.024). No differences in clinical severity of hand eczema were found. The interviewees were generally satisfied with the counselling and the website. The strict log-on procedures were considered to be an obstacle to using the site. The consecutive inclusion of participants was considered to be a barrier to engagement in the dialogue forum. The website users benefited from the website, although this was not substantiated by clinical measurements. The trial design partly hampered website utilization. An initial feasibility study could have been warranted. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

The Quality of Life in Hand Eczema Questionnaire (QOLHEQ) is the only instrument assessing disease-specific health-related quality of life in patients with hand eczema. It is available in eight language versions. In this study we assessed if the items of different language versions of the QOLHEQ yield comparable values across countries. An international multicenter study was conducted with participating centers in Finland, Germany, Japan, The Netherlands, Sweden, and Turkey. Methods of item response theory were applied to each subscale to assess differential item functioning for items among countries. Overall, 662 hand eczema patients were recruited into the study. Single items were removed or split according to the item response theory model by country to resolve differential item functioning. After this adjustment, none of the four subscales of the QOLHEQ showed significant misfit to the item response theory model (P < 0.01), and a Person Separation Index of greater than 0.7 showed good internal consistency for each subscale. By adapting the scoring of the QOLHEQ using the methods of item response theory, it was possible to obtain QOLHEQ values that are comparable across countries. Cross-cultural variations in the interpretation of single items were resolved. The QOLHEQ is now ready to be used in international studies assessing the health-related quality of life impact of hand eczema. Copyright © 2017 The Authors. Published by Elsevier Inc.

Background Atopic eczema (AE) is a common chronic inflammatory skin disorder. In order to dissect the genetic background several linkage and genetic association studies have been performed. Yet very little is known about specific genes involved in this complex skin disease, and the underlying molecular mechanisms are not fully understood. Methodology/Findings We used human DNA microarrays to identify a molecular picture of the programmed responses of the human genome to AE. The transcriptional program was analyzed in skin biopsy samples from lesional and patch-tested skin from AE patients sensitized to Malassezia sympodialis (M. sympodialis), and corresponding biopsies from healthy individuals. The most notable feature of the global gene-expression pattern observed in AE skin was a reciprocal expression of induced inflammatory genes and repressed lipid metabolism genes. The overall transcriptional response in M. sympodialis patch-tested AE skin was similar to the gene-expression signature identified in lesional AE skin. In the constellation of genes differentially expressed in AE skin compared to healthy control skin, we have identified several potential susceptibility genes that may play a critical role in the pathological condition of AE. Many of these genes, including genes with a role in immune responses, lipid homeostasis, and epidermal differentiation, are localized on chromosomal regions previously linked to AE. Conclusions/Significance Through genome-wide expression profiling, we were able to discover a distinct reciprocal expression pattern of induced inflammatory genes and repressed lipid metabolism genes in skin from AE patients. We found a significant enrichment of differentially expressed genes in AE with cytobands associated to the disease, and furthermore new chromosomal regions were found that could potentially guide future region-specific linkage mapping in AE.

Eczema may flare because of bacterial infection, but evidence supporting antibiotic treatment is of low quality. We aimed to determine the effect of oral and topical antibiotics in addition to topical emollient and corticosteroids in children with clinically infected eczema. We employed a 3-arm, blinded, randomized controlled trial in UK ambulatory care. Children with clinical, non-severely infected eczema were randomized to receive oral and topical placebos (control), oral antibiotic (flucloxacillin) and topical placebo, or topical antibiotic (fusidic acid) and oral placebo, for 1 week. We compared Patient Oriented Eczema Measure (POEM) scores at 2 weeks using analysis of covariance (ANCOVA). We randomized 113 children (40 to control, 36 to oral antibiotic, and 37 to topical antibiotic). Mean (SD) baseline Patient Oriented Eczema Measure scores were 13.4 (5.1) for the control group, 14.6 (5.3) for the oral antibiotic group, and 16.9 (5.5) for the topical antibiotic group. At baseline, 104 children (93%) had 1 or more of the following findings: weeping, crusting, pustules, or painful skin. Mean (SD) POEM scores at 2 weeks were 6.2 (6.0) for control, 8.3 (7.3) for the oral antibiotic group, and 9.3 (6.2) for the topical antibiotic group. Controlling for baseline POEM score, neither oral nor topical antibiotics produced a significant difference in mean (95% CI) POEM scores (1.5 [-1.4 to 4.4] and 1.5 [-1.6 to 4.5] respectively). There were no significant differences in adverse effects and no serious adverse events. We found rapid resolution in response to topical steroid and emollient treatment and ruled out a clinically meaningful benefit from the addition of either oral or topical antibiotics. Children seen in ambulatory care with mild clinically infected eczema do not need treatment with antibiotics. © 2017 Annals of Family Medicine, Inc.

Objective Occupational hand eczema has adverse health and socioeconomic impacts for the afflicted individuals and society. Prevention and treatment strategies are needed. This study aimed to assess the effectiveness of an educational intervention on sickness absence, quality of life and severity of hand eczema. Methods PREVEX (PreVention of EXema) is an individually randomized, parallel-group superiority trial investigating the pros and cons of one-time, 2-hour, group-based education in skin-protective behavior versus treatment as usual among patients with newly notified occupational hand eczema, with follow-up after one year. Co-primary outcomes were total sickness absence, health-related quality of life (HR-QoL), and self-reported severity of hand eczema. Results Patients (N=1668) with notified occupational skin diseases from July 2012 to November 2014 were invited to participate in the trial. Of these, 756 were randomized to the intervention (N= 376) versus control (N=380) group. The intervention group had 21% fewer sickness absence days compared with the control group [95% confidence interval (CI) -55-40%, P=0.43]. We found no significant difference in the change of HR-QoL for the intervention compared with the control group (4% lower in the intervention group, 95% CI -18-13%, P=0.67). The ordinal odds of scoring worse on self-reported hand eczema severity was 15% lower in the intervention compared with the control group (95% CI -39-18%, P=0.34). Post-hoc sub-group analyses indicated that the effect of the intervention on severity differed between occupations, being detrimental to healthcare workers and beneficial in all other occupations. Conclusion The educational skincare program had no marked effect on the primary outcomes sickness absence, HR-QoL, and severity of hand eczema when compared with treatment as usual.

Hand eczema is a common inflammatory dermatosis that causes significant patient morbidity. Previous studies comparing psoralen-ultraviolet A (PUVA) with narrowband ultraviolet B (NB-UVB) have been small, nonrandomized and retrospective. To conduct an observer-blinded randomized controlled pilot study using validated scoring criteria to compare immersion PUVA with NB-UVB for the treatment of chronic hand eczema unresponsive to topical steroids. Sixty patients with hand eczema unresponsive to clobetasol propionate 0·05% were randomized to receive either immersion PUVA or NB-UVB twice weekly for 12 weeks with assessments at intervals of 4 weeks. The primary outcome measure was the proportion of patients achieving 'clear' or 'almost clear' Physician's Global Assessment (PGA) response at 12 weeks. Secondary outcome measures included assessment of the modified Total Lesion and Symptom Score (mTLSS) and the Dermatology Life Quality index (DLQI). In both treatment arms, 23 patients completed the 12-week assessment for the primary outcome measure. In the PUVA group, five patients achieved 'clear' and eight 'almost clear' [intention-to-treat (ITT) response rate 43%]. In the NB-UVB group, two achieved 'clear' and five 'almost clear' (ITT response rate 23%). For the secondary outcomes, median mTLSS scores were similar between groups at baseline (PUVA 9·5, NB-UVB 9) and at 12 weeks (PUVA 3, NB-UVB 4). Changes in DLQI were similar, with improvements in both groups. In this randomized pilot trial recruitment was challenging. After randomization, there were acceptable levels of compliance and safety in each treatment schedule, but lower levels of retention. Using validated scoring systems - PGA, mTLSS and DLQI - as measures of treatment response, the trial demonstrated that both PUVA and NB-UVB reduced the severity of chronic palmar hand eczema. © 2017 British Association of Dermatologists.

Allergic contact dermatitis (ACD) may complicate the clinical course of atopic dermatitis (AD), and patch testing remains the criterion standard for diagnosing ACD. To date, there have been no guidelines or consensus recommendations on when and how to patch test individuals with AD. Failure to patch test when appropriate may result in overlooking an important and potentially curable complicating comorbidity. In this article, we present consensus recommendations regarding when to perform patch testing in the AD patient, best practices, and common pitfalls. Patch testing should be considered in AD patients with dermatitis that fails to improve with topical therapy; with atypical/changing distribution of dermatitis, or pattern suggestive of ACD; with therapy-resistant hand eczema in the working population; with adult- or adolescent-onset AD; and/or before initiating systemic immunosuppressants for the treatment of dermatitis. A suggested patch testing algorithm for AD patients is provided.

Filaggrin loss-of-function (FLG-LOF) mutations are an established genetic cause of eczema. These mutations have subsequently been reported to increase the risk of aeroallergen sensitization and allergic airway disease. However, it is unclear whether FLG variants require both eczema and aeroallergen sensitization to influence airway disease development long-term outcomes. To examine the effects of FLG-LOF mutations on allergic airway disease outcomes, with eczema and aeroallergen sensitization as intermediate variables, using the Isle of Wight birth cohort. Study participants were evaluated at ages 1, 2, 4, 10 and 18 years to ascertain the development of allergic diseases (eczema, asthma and allergic rhinitis) and aeroallergen sensitization (determined by skin prick tests). FLG-LOF mutations were genotyped in 1150 subjects. To understand the complex associations between FLG mutations, intermediate variables (eczema and aeroallergen sensitization) and airway disease, path analysis was performed. There were significant total effects of FLG-LOF mutations on both asthma and allergic rhinitis at all ages as well as on aeroallergen sensitization up till 10 years old. In the filaggrin-asthma analysis, a direct effect of FLG-LOF mutations was observed on early childhood eczema (age 1 and 2 years) (relative risk (RR) 2.01, 95% CI: 1.74-2.31, P < .001), and all significant indirect pathways on asthma outcomes passed through eczema at these ages. In contrast, for the filaggrin-rhinitis model, FLG-LOF mutations exerted significant direct effects on early eczema as well as rhinitis at 10 years (RR 1.99; 95% CI: 1.72-2.29, P = .002). FLG-LOF mutations are a significant risk factor for later childhood asthma and rhinitis. However, the pathway to asthma is only through early childhood eczema while a direct effect was observed for childhood rhinitis. © 2017 John Wiley & Sons Ltd.

Sleep and neurocognitive functioning in children with eczema.

Sleep disruption in childhood is associated with clearly defined deficits in neurocognition and behaviour. Childhood eczema is also a potent cause of sleep disruption though it is unknown whether it too results in neurocognitive deficits. To test this hypothesis, neurocognitive (WISC-IV), parental-reported sleep quality (Sleep Disturbance Scale of Children (SDSC)) and overnight polysomnographic (PSG) data were collected in 21 children with eczema and 20 healthy controls (age range 6-16 years). Children with eczema had worse sleep quality on both PSG (notably increased nocturnal wakefulness, a higher number of stage shifts and a longer latency to REM onset) and parental report. In addition, they demonstrated significant neurocognitive deficits (especially verbal comprehension, perceptual reasoning and to a lesser extent working memory) with a composite Full Scale IQ 16 points lower than controls. Parental reported sleep problems but not PSG parameters were correlated with reduced neurocognitive performance. However, hierarchical regression analyses revealed that eczema status was predictive while sleep fragmentation (parental or PSG) was not predictive of neurocognitive performance. As this is the first study to systematically examine neurocognitive functioning in children with eczema and given the finding of significant deficits it merits replication especially given the prevalence of the condition. The unanswered question is whether these cognitive deficits normalise with effective eczema treatment and if this is mediated by improvements in sleep architecture. Crown Copyright © 2013.

Hand eczema is an impacting cutaneous disease. Globally valid tools that help to diagnose hand and forearm eczema are required. To validate the questions to detect hand and/or forearm eczema included in the "Nordic Occupational Skin Questionnaire" (NOSQ-2002) in the Spanish language. A prospective pilot study was conducted with 80 employees of a cleaning company and a retrospective one involving 2,546 individuals. The responses were analysed for sensitivity, specificity and positive and negative predictive values. The final diagnosis according to the patients' hospital records, the specialty care records and the physical examination was taken as gold standard. The Dermatology Life Quality Index (DLQI) was also evaluated. Sensitivity and specificity, in a worst case scenario (WC) combining both questions, were 96.5% and 66.7%, respectively, and in a per protocol (PP) analysis, were 96.5% and 75.2%. The questions validated detected eczema effectively, making this tool suitable for use e.g. in multicentre epidemiological studies or clinical trials.

Secondary skin infection is common during eczema exacerbations and many children are treated with antibiotics when this is suspected, although there is little high-quality evidence to justify this practice. To determine the clinical effectiveness of oral and topical antibiotics, in addition to standard treatment with emollients and topical corticosteroids, in children with clinically infected eczema. Multicentre randomised, double-blind, placebo-controlled trial. General practices and dermatology clinics in England, Wales and Scotland. Children (aged 3 months to < 8 years) with a diagnosis of eczema (according to U.K. Working Party definition) and clinical suspicion of infection. (1) Oral flucloxacillin and topical placebo; (2) topical fusidic acid (Fucidin(®), Leo Laboratories Limited) and oral placebo; and (3) oral and topical placebos, all for 1 week. Patient-Orientated Eczema Measure (POEM) at 2 weeks (assessing subjective severity in the week following treatment). We randomised 113 children (36 to oral antibiotic, 37 to topical antibiotic and 40 to placebo), which was fewer than our revised target sample size of 282. A total of 103 (92.0%) children had one or more clinical features suggestive of infection and 78 (69.6%) children had Staphylococcus aureus cultured from a skin swab. Oral and topical antibiotics resulted in a 1.52 [95% confidence interval (CI) -1.35 to 4.40] and 1.49 (95% CI -1.55 to 4.53) increase (worse subjective severity) in POEM score at 2 weeks, relative to placebo and controlling for baseline POEM score. Eczema Area and Severity Index (objective severity) scores were also higher (worse) in the intervention groups, at 0.20 (95% CI -0.12 to 0.52) and 0.42 (95% CI 0.09 to 0.75) for oral and topical antibiotics, respectively, at 2 weeks. Analyses of impact on the family, quality of life, daily symptom scores, and longer-term outcomes were all consistent with the finding of no or limited difference and a trend towards worse outcomes in the intervention groups. Sensitivity analyses, including adjusting for compliance and imputation for missing data, were consistent with the main findings. Our data suggest that oral and topical antibiotics have no effect, or a harmful effect, on subjective eczema severity in children with clinically infected eczema in the community. The CIs around our estimates exclude a meaningful beneficial effect (published minimal clinically important difference for POEM is 3.4). Although most patients in this trial had features suggestive of infection and S. aureus on their skin, participants primarily had mild-moderate eczema and those with signs of more severe infection were often excluded. Clinicians should consider avoiding oral and topical antibiotic use in children with suspected infected eczema in the community who do not have signs of 'severe infection'. Further research should seek to understand how best to encourage the use of topical steroids and limit use of antibiotics in those with eczema flares without signs of severe infection, as well as developing tools to better phenotype eczema flares, in order to better define a population that may benefit from antibiotic treatment.

Tacrolimus treatment of atopic eczema/dermatitis syndrome.

PubMed

Thestrup-Pedersen, Kristian

2003-10-01

Atopic dermatitis is today the most common chronic disease of children in Europe, the US and Japan. The 'golden standard' of therapy is topical glucocorticosteroids and emollients. The steroids have been on the market for four decades, are efficacious, but only advised for short-term treatment due to their risks of side effects. More than 16,000 persons suffering from atopic dermatitis have been enrolled in clinical studies of tacrolimus. One third of patients with moderate to severe atopic dermatitis experience over 90% improvement in their disease over a 12-week treatment period and up to 70% of patients have over 50% improvement. A 1-year treatment leads to more than 90% improvement in 75% of patients. The most pronounced side effect is a burning sensation occurring in up to 60% of patients. Atopic dermatitis is a chronic skin disease leading to a demand for long-term treatment control. Such treatment options have not previously been available--except for emollients which are not efficacious for controlling skin inflammation. Tacrolimus and pimecrolimus are new treatment options, free from the potential side effects of topical steroids, which are known for their efficacy in short-term treatment. The new treatment modalities prevent the eczema from relapsing and at the same time they control active eczema. The future will see a shift towards the long-term use of tacrolimus which is able to control the skin inflammation and, hopefully, shorten the course of the eczema.

Integrated, multidisciplinary care for hand eczema: design of a randomized controlled trial and cost-effectiveness study

PubMed Central

2009-01-01

Background The individual and societal burden of hand eczema is high. Literature indicates that moderate to severe hand eczema is a disease with a poor prognosis. Many patients are hampered in their daily activities, including work. High costs are related to high medical consumption, productivity loss and sick leave. Usual care is suboptimal, due to a lack of optimal instruction and coordination of care, and communication with the general practitioner/occupational physician and people involved at the workplace. Therefore, an integrated, multidisciplinary intervention involving a dermatologist, a care manager, a specialized nurse and a clinical occupational physician was developed. This paper describes the design of a study to investigate the effectiveness and cost-effectiveness of integrated care for hand eczema by a multidisciplinary team, coordinated by a care manager, consisting of instruction on avoiding relevant contact factors, both in the occupational and in the private environment, optimal skin care and treatment, compared to usual, dermatologist-led care. Methods The study is a multicentre, randomized, controlled trial with an economic evaluation alongside. The study population consists of patients with chronic, moderate to severe hand eczema, who visit an outpatient clinic of one of the participating 5 (three university and two general) hospitals. Integrated, multidisciplinary care, coordinated by a care manager, including allergo-dermatological evaluation by a dermatologist, occupational intervention by a clinical occupational physician, and counselling by a specialized nurse on optimizing topical treatment and skin care will be compared with usual care by a dermatologist. The primary outcome measure is the cumulative difference in reduction of the clinical severity score HECSI between the groups. Secondary outcome measures are the patient's global assessment, specific quality of life with regard to the hands, generic quality of life, sick leave and patient satisfaction. An economic evaluation will be conducted alongside the RCT. Direct and indirect costs will be measured. Outcome measures will be assessed at baseline and after 4, 12, 26 and 52 weeks. All statistical analyses will be performed on the intention-to-treat principle. In addition, per protocol analyses will be carried out. Discussion To improve societal participation of patients with moderate to severe hand eczema, an integrated care intervention was developed involving both person-related and environmental factors. Such integrated care is expected to improve the patients' clinical signs, quality of life and to reduce sick leave and medical costs. Results will become available in 2011. PMID:19951404

Eczema is an inflammatory skin disease that tends to involve skin creases, such as the folds of the elbows or knees; it is an intensely itchy skin condition, which can relapse and remit over time. As many as a third of people with eczema who have a positive test for allergy to house dust mite have reported worsening of eczema or respiratory symptoms when exposed to dust. To assess the effects of all house dust mite reduction and avoidance measures for the treatment of eczema. We searched the following databases up to 14 August 2014: the Cochrane Skin Group Specialised Register, CENTRAL in The Cochrane Library (2014, Issue 8), MEDLINE (from 1946), Embase (from 1974), LILACS (from 1982), and the GREAT database. We also searched five trials registers and checked the reference lists of included and excluded studies for further references to relevant studies. We handsearched abstracts from international eczema and allergy meetings. Randomised controlled trials (RCTs) of any of the house dust mite reduction and avoidance measures for the treatment of eczema, which included participants of any age diagnosed by a clinician with eczema as defined by the World Allergy Organization. We included all non-pharmacological and pharmacological interventions that sought to reduce or avoid exposure to house dust mite and their allergenic faeces. The comparators were any active treatment, no treatment, placebo, or standard care only. Two authors independently checked the titles and abstracts identified, and there were no disagreements. We contacted authors of included studies for additional information. We assessed the risk of bias using Cochrane methodology. We included seven studies of 324 adults and children with eczema. Overall, the included studies had a high risk of bias. Four of the seven trials tested interventions with multiple components, and three tested a single intervention. Two of the seven trials included only children, four included children and adults, and one included only adults. Interventions to reduce or avoid exposure to house dust mite included covers for mattresses and bedding, increased or high-quality vacuuming of carpets and mattresses, and sprays that kill house dust mites.Four studies assessed our first primary outcome of 'Clinician-assessed eczema severity using a named scale'. Of these, one study (n = 20) did not show any significant short-term benefit from allergen impermeable polyurethane mattress encasings and acaricide spray versus allergen permeable cotton mattress encasings and placebo acaricide spray. One study (n = 60) found a modest statistically significant benefit in the Six Area, Six Sign Atopic Dermatitis (SASSAD) scale over six months (mean difference of 4.2 (95% confidence interval 1.7 to 6.7), P = 0.008) in favour of a mite impermeable bedding system combined with benzyltannate spray and high-filtration vacuuming versus mite permeable cotton encasings, water with a trace of alcohol spray, and a low-filtration vacuum cleaner. The third study (n = 41) did not compare the change in severity of eczema between the two treatment groups. The fourth study (n = 86) reported no evidence of a difference between the treatment groups.With regard to the secondary outcomes 'Participant- or caregiver-assessed global eczema severity score' and the 'Amount and frequency of topical treatment required', one study (n = 20) assessed these outcomes with similar results being reported for these outcomes in both groups. Four studies (n = 159) assessed 'Sensitivity to house dust mite allergen using a marker'; there was no clear evidence of a difference in sensitivity levels reported between treatments in any of the four trials.None of the seven included studies assessed our second primary outcome 'Participant- or caregiver-assessed eczema-related quality of life using a named instrument' or the secondary outcome of 'Adverse effects'.We were unable to combine any of our results because of variability in the interventions and paucity of data. We were unable to determine clear implications to inform clinical practice from the very low-quality evidence currently available. The modest treatment responses reported were in people with atopic eczema, specifically with sensitivity to one or more aeroallergens. Thus, their use in the eczema population as a whole is unknown. High-quality long-term trials of single, easy-to-administer house dust mite reduction or avoidance measures are worth pursuing.

Hydroxyisohexyl 3-cyclohexene carboxaldehyde (HICC)-Lyral® is a widely used synthetic fragrance found in personal care and household products. It is an aldehyde, lipophilic enough to penetrate the skin and is a frequent cause of contact sensitization. Describe the frequency of contact allergy to HICC in a Contact Dermatitis Unit, after its inclusion in baseline patch test series. A retrospective study including all patients submitted to patch test, from January 2007 to December 2009. Over a 3-year period, 629 consecutive patients were patch tested. The frequency of positive reactions to HICC was 2.7% (17/629). Of the positive patients, 35% (6/17) gave a history of atopy, 58.8% (10/17) had eczema on the face and neck, 23.5% (4/17) on the hands, 23.5% (4/17) in the axillae, 17.6% (3/17) on the trunk and 6% (3/17) had generalized eczema. All patients were patch positive for more than one allergen: all (17/17) positive to fragrance Mix 2 (FM2); 47% of the patients (8/17) positive to fragrance Mix 1 (FM1); and 23.5% of the patients (4/17) positive to Balsam of Peru. In 94% (16/17) of cases, the reaction was judged to be of current relevance. The frequency of positive reactions to HICC of 2.7% found in our population is according to what is described in several European reports, where HICC is still widely used as a fragrance ingredient. In contrast, in North America, the prevalence is lower. All the patients were positive also to FM2. The association found between reactions to FM1 and HICC is also commonly reported and could represent a concomitant sensitization following increased exposure to fragrance allergens. These data confirm the importance of HICC introduction in the baseline patch test series.

Hydroxyisohexyl 3-cyclohexene carboxaldehyde, also known as Lyral, is a fragrance ingredient identified as the cause of contact allergic reactions in 2-3% of eczema patients undergoing patch testing. Lyral has been included in the standard patch test series in many clinics due to its importance as an allergen. It has been used without restrictions in cosmetic products, until now. In the present study, the dose-response relationship of Lyral contact allergy was studied with doses relevant for normal exposure in cosmetic products. 18 eczema patients, who previously had given a positive patch test to Lyral 5% petrolatum, were included along with 7 control subjects. All cases were tested with a serial dilution of Lyral in ethanol 6% to 6 p.p.m and subjected to a 2-week, repeated open application test with a low dose of Lyral in ethanol. In the case of no reaction, this was followed by another 2 weeks of testing with a higher dose. The test was performed at the volar aspect of the forearm. In 16 of 18 cases (89%), a positive use test developed, 11 reacting to the low and 5 to the high concentration. None reacted to the vehicle control of ethanol applied to the contralateral arm. All controls were negative to both the test solutions of Lyral and the ethanol control. The difference between the test and the control group was statistically significant (Fisher's test, P < 0.001). It is concluded that Lyral at the current usage levels is inducing sensitization in the community. The same levels were shown to elicit allergic contact dermatitis in almost all sensitized individuals. A significant reduction in usage concentrations is recommended to prevent contact allergic reactions.

Improving Value for Patients with Eczema.

Block, Julie

2018-04-01

Chronic diseases now represent a cost majority in the United States health care system. Contributing factors to rising costs include expensive novel and emerging therapies, under-treatment of disease, under-management of comorbidities, and patient dissatisfaction with care results. Critical to identifying replicable improvement methods is a reliable model to measure value. If we understand value within healthcare consumerism to be equal to a patient's health outcome improvement over costs associated with care (Value=Outcomes/Costs), we can use this equation to measure the improvement of value. Research and literature show that patient activation-the skills and confidence that equip patients to become actively engaged in their health care-impact health outcomes, costs, and patient experience. Reaching patient activation through engagement methods including shared decision-making (SDM) lead to improved value of care received. The National Eczema Association (NEA) Shared Decision-Making Resource Center can be a transformative strategy to measure and evaluate value of health care interventions for eczema patients to advance a value-driven health care system in the United States. Through this Resource Center, NEA will measure patient value through their own perceptions using validated PRO instruments and other patient-generated health data. Assessment of this data will reveal findings that can assist researchers in evaluating the impact this care framework on patient-perceived value across other chronic diseases.

An association between nickel contact allergy and hand eczema has previously been demonstrated. In 1990, Denmark regulated the extent of nickel release in the ear-piercing process as well as nickel release from consumer products. This study aimed to evaluate the effect of the Danish nickel regulation by comparing the prevalence of concomitant nickel allergy and hand eczema observed in two repeated cross-sectional studies performed in the same general population in Copenhagen. In 1990 and 2006, 3881 18-69 year olds completed a postal questionnaire and were patch tested with nickel. Data were analysed by logistic regression analyses and associations were expressed as odds ratios (ORs) with 95% confidence intervals (CIs). The prevalence of concomitant nickel contact allergy and a history of hand eczema decreased among 18-35-year-old women from 9.0% in 1990 to 2.1% in 2006 (P < 0.01). The association between nickel contact allergy and a history of hand eczema decreased in this age group between 1990 (OR = 3.63; CI = 1.33-9.96) and 2006 (OR = 0.65; CI = 0.29-1.46). Among older women, no significant changes were observed in the association between nickel contact allergy and hand eczema. Regulatory control of nickel exposure may have reduced the effect of nickel on hand eczema in the young female population.

In the year 2000, the level of methyldibromo glutaronitrile (MDGN) allergy in dermatology clinics in Europe exceeded the level of allergies to all other preservatives, with a prevalence of 3.5%. In the present study, cases of primary sensitization and elicitation to MDGN due to cosmetic products were collected over an 8-month period at the Department of Dermatology, Gentofte University Hospital. The aim was to identify the products related to hand eczema, assess exposure to MDGN in these products and relate the findings to results from a newly developed updated risk assessment model for contact allergy. Out of 24 patients with a positive patch test to MDGN, 17 patients with hand eczema were identified. In 11 of these patients, cosmetic products used in relation to the onset of the disease were shown to contain MDGN (65%). In 8 of these 11 cases, primary sensitization was probable, 5 due to hand/body lotions and 3 due to lotions and/or liquid hand soap. Chemical analysis of 12 products showed that lotions contained 149-390 ppm of MDGN, liquid hand soap 144-399 ppm, a rinsing cream 293 ppm and shampoos 78-79 ppm. The shampoo exposure was not of certain relevance to the eczema. Applying the newly developed updated risk assessment model showed that the concentrations of MDGN in lotions of 149-390 ppm exceeded the calculated maximum acceptable exposure level for MDGN, which would be expected to lead to sensitization in consumers using such products, as seen in the current study. The present cases and updated exposure-based risk assessment process add to the evidence and need for re-defining safe-use concentrations of MDGN in cosmetic products.

Background Epidemiological studies and anecdotal reports suggest a possible link between household use of hard water and atopic eczema. We sought to test whether installation of an ion-exchange water softener in the home can improve eczema in children. Methods and Findings This was an observer-blind randomised trial involving 336 children (aged 6 months to 16 years) with moderate/severe atopic eczema. All lived in hard water areas (≥200 mg/l calcium carbonate). Participants were randomised to either installation of an ion-exchange water softener plus usual eczema care, or usual eczema care alone. The primary outcome was change in eczema severity (Six Area Six Sign Atopic Dermatitis Score, SASSAD) at 12 weeks, measured by research nurses who were blinded to treatment allocation. Analysis was based on the intent-to-treat population. Eczema severity improved for both groups during the trial. The mean change in SASSAD at 12 weeks was −5.0 (20% improvement) for the water softener group and −5.7 (22% improvement) for the usual care group (mean difference 0.66, 95% confidence interval −1.37 to 2.69, p = 0.53). No between-group differences were noted in the use of topical corticosteroids or calcineurin inhibitors. Conclusions Water softeners provided no additional benefit to usual care in this study population. Small but statistically significant differences were found in some secondary outcomes as reported by parents, but it is likely that such improvements were the result of response bias, since participants were aware of their treatment allocation.

Background Associations of filaggrin (FLG) variants with asthma and rhinitis have been shown to be modulated by eczema status. However, it is unknown whether allergic sensitization status modifies this association. The aim of this study was to determine whether FLG variants need eczema and/or allergic sensitization as a necessary component to execute its adverse effect on coexisting and subsequent asthma and rhinitis. Methods Repeated measurements of asthma, rhinitis, eczema, and allergic sensitization (documented by skin prick tests) at ages 1, 2, 4, 10, and 18 years were ascertained in the Isle of Wight birth cohort (n = 1,456). FLG haploinsufficiency was defined as having at least the minor allele of R501X, 2282del4, or S3247X variants. Log binomial regression models were used to test associations and statistical interactions. Results FLG variants increased the risk of asthma (RR = 1.39, 95% CI: 1.06 – 1.80) and rhinitis (RR = 1.37, 95% CI: 1.16 – 1.63). In delayed effect models, ‘FLG variants plus allergic sensitization’ and ‘FLG variants plus eczema’ increased the risk of subsequent asthma by 4.93-fold (95% CI: 3.61 – 6.71) and 3.33-fold (95% CI: 2.45 – 4.51), respectively, during the first 18 years of life. In contrast, neither eczema nor allergic sensitization in combination with FLG variants increased the risk of later rhinitis. Conclusions Allergic sensitization and eczema modulated the association between FLG variants and asthma, but not rhinitis. Results of our study imply that the mechanisms and pathways through which FLG variants predispose to increased risk of asthma and rhinitis may be different. PMID:25277085

1997-06-01

The aim of the study was to investigate the elicitation potential of perfumes from 17 commonly sold lower-price cosmetic products. 8 of the perfumes were from stay-on cosmetics and 9 were from wash-off cosmetics. Each perfume was tested in 500 consecutive eczema patients, who also were tested with the European standard patch test series. 4.2% reacted to 1 or more of the wash-off product perfumes and 3.2% to 1 or more of the stay-on product perfumes. Concordant positive reactions between the fragrance mix and the product perfumes were found in 81.3% of positive reactions to the stay-on product perfumes and in 52.4% of the reactions to the wash-off product perfumes. Compared to the fragrance mix alone, only 1 additional case of contact allergy to the product perfumes was detected by balsam of Peru. Chemical analysis revealed that between 1 and 5 of the chemically-defined constituents of the fragrance mix were present in all of the product perfumes. Geraniol was found in 12 of the 17 perfumes and was most often detected. The concentration of the target fragrance materials ranged from 0.005%-1.35 w/v%. It is concluded that the allergenic constituents of the fragrance mix are impossible to avoid if perfumed cosmetics are used. Furthermore, patients suspected of perfume allergy need to be tested with their own perfumed products, as far from all cases of perfume allergy are detected by the fragrance mix and/or balsam of Peru in the European standard patch test series.

Psychiatric Treatment of Eczema: A Controlled Trial

Seventy-two patients with eczema were randomly allotted to one of two treatment groups: A, those receiving dermatological treatment only, and B, those receiving the same dermatological treatment plus psychiatric treatment, limited where possible to four months. Cases were followed up at six-monthly dermatological assessments, 57 (79%) for 18 months. The findings suggest that in the presence of overt emotional disturbance, of new psychological or psychophysiological symptoms preceding the rash by up to a year, and of high motivation for it, brief psychiatric treatment improves the outcome in eczema (the proportion clear at 18 months was about doubled), whereas in their absence such treatment may worsen it, especially in the short term.

Eczema is characterized by itching, lichenification, scaling, oedema and erythema. Current management strategies include corticosteroids, which are limited due to side effects. Many herbal remedies are used traditionally but unfortunately have not been validated in controlled clinical trials. Three popular traditional treatments of eczema include Indian pennywort, Walnut and Turmeric. In this study three topical formulations (micro emulsion, gel and ointment) were prepared from extracts of Indian pennywort, Walnut and Turmeric. These formulations were monitored for stability for a period of three months. Controlled clinical trials were conducted on 360 eczema patients. Clinical parameters observed were degree of erythema, oedema, scaling, itching and lichenification. Effects of each formulation on these clinical parameters were compared with placebo formulations. Micro emulsion formulations in all cases proved to be more effective in reducing semi quantitative scores of erythema and oedema. Itching was relieved more by gel formulation. The ointment showed more efficacy towards scaling and lichenification. Comparison of the effects of placebo and the specific formulations was performed by chi-square statistics and found to be highly significant. In summary it is concluded that all the formulations could be used as promising source for treatment of eczema.

Probiotics: immunomodulatory properties in allergy and eczema.

PubMed

Drago, L; Toscano, M; Pigatto, P D

In the last decades the prevalence of allergic diseases and eczema raised significantly, and today they are the most common chronic pathologies affecting children. It has been shown that a functional intestinal mucosa provides a defensive barrier to the host against potential dangerous antigens, regulating the tolerance to them. Some inflammatory diseases of the gut weaken the barrier causing an increase in the mucosa permeability and in antigenic transition. As a consequence, there is an aberrant immune response and the release of pro-inflammatory cytokines further compromises the barrier functionality. It has been demonstrated that a correlation between allergy and eczema onset and the intestinal microflora composition exists, and in particular, it has been showed that some microorganisms are able to influence the immune response. For these reasons it has been hypothesized that probiotics may have a beneficial role in preventing and treating allergies and eczema. However, the benefits of this treatment depend on many factors, such as the bacterial strain, the duration of administration, the pathology, the patient characteristics (age, diet, allergy predisposition). The aim of this work was to review the present knowledge about the use of probiotics in allergic diseases and eczema, highlighting their role in the aforementioned pathologies.

Cupping Therapy May be Harmful for Eczema: A PubMed Search

2013-01-01

Eczema is a common childhood atopic condition and treatment is with emollients, topical corticosteroids, and avoidance of possible triggers. S. aureus colonization is a common complication. As there is no immediate cure, many parents seek alternative therapies that claim unproven therapeutic efficacy. We report a girl with long history of treatment noncompliance. After practicing a long period of dietary avoidance and supplementation, the grandparents took her to an alternative medicine practitioner. Following cupping therapy and acupuncture, the child developed blistering and oozing over her back the next day, which rapidly evolved to two large irregular-edge deep ulcers. She was treated with intravenous antibiotics and received multidisciplinary supportive intervention. Using search words of  “cupping,” “eczema,” and “atopic dermatitis,” only two reports were found on PubMed. Therapeutic efficacy was claimed but not scientifically documented in these reports. Childhood eczema is an eminently treatable atopic disease. Extreme alternative therapy seems not to be efficacious and may even be associated with serious undesirable sequelae. Physicians should be aware of various alternative treatment modalities and be prepared to offer evidence-based advice to the patients with eczema and their families. PMID:24282650

Family eczema-history in 2-year olds with eczema; a prospective, population-based study. The PACT-study, Norway

PubMed Central

2011-01-01

Background A maternal line of inheritance regarding eczema has been described in several studies, whereas others find associations to both a maternal as well as a paternal line of inheritance. When studying family history of eczema symptoms, cohort studies including siblings are rare. Time point for assessing family eczema-history could be of importance when studying the associations between family eczema-history and children with eczema, as parents with unaffected children may not recall mild symptoms in other siblings or their own disease history. We therefore aimed to study the associations between reported eczema in mother, father and siblings and reported eczema in index child where information on family history was collected at two different ages of index child. Methods Parents/children participating in The Prevention of Allergy among Children in Trondheim (PACT) study were given questionnaires on reported eczema symptoms in mother, father and siblings at 6 weeks and 1 year. When index child was 2 years of age, a detailed questionnaire on different health issues with emphasize on different allergy related disorders were filled in. Results Both maternal and paternal reports on eczema were significantly associated with eczema in index child. Reporting family eczema-history at 1 year (N = 3087), "eczema sibling only" [adjusted odds ratio (aOR) = 3.13 (2.27-4.33)] as well as all other family-groups containing siblings with eczema were strongly associated with eczema 2 years. When family eczema-history was reported at 6 weeks (N = 2657), reporting of "eczema sibling only" was not associated to reported eczema at 2 years in index child [aOR = 1.31 (0.77-2.23)]. Conclusions Having sibling(s) with eczema strengthened the associations between maternal and paternal reports on eczema with eczema in index child only when exposure was reported at 1 year. These findings indicate that results from questionnaires-based studies of family eczema-history depend on whether or not index child has yet developed eczema.

Patients with moderate-to-severe atopic eczema (AE) often require photo- or systemic immunomodulatory therapies to induce disease remission and maintain long-term control. The current evidence to guide clinical management is small, despite the frequent and often off-label use of these treatments. Registries of patients on photo- and systemic immunomodulatory therapies could fill this gap, and the collection of a core set concerning these therapies in AE will allow direct comparisons across registries as well as data sharing and pooling. Using an eDelphi approach, the international TREatment of ATopic eczema (TREAT) Registry Taskforce aims to seek consensus between key stakeholders internationally on a core set of domains and domain items for AE patient registries with a research focus that collect data of children and adults on photo- and systemic immunomodulatory therapies. Participants from six stakeholder groups will be invited: doctors, nurses, non-clinical researchers, patients, as well as industry and regulatory body representatives. The eDelphi will comprise three sequential online rounds, requesting participants to rate the importance of each proposed domain and domain items. Participants will be able to add domains and domain items to the proposed list in round 1. A final consensus meeting will be held with representatives of each stakeholder group. Identifying a uniform core set of domains and domain items to be captured by AE patient registries will increase the utility of individual registries, and provide greater insight into the effectiveness, safety and cost-effectiveness of photo- and systemic immunomodulatory therapies to guide clinical management across dermatology centres and country borders. Not applicable. This eDelphi study was registered in the Core Outcome Measures for Effectiveness Trials (COMET) database.

The lack of core outcome sets for atopic eczema (AE) is a major obstacle for advancing evidence-based treatment. The global Harmonising Outcome Measures for Eczema (HOME) initiative has already defined clinical signs, symptoms, quality of life, and long-term control of flares as core outcome domains for AE trials. This article deals with the standardization of measurement instruments to assess clinical signs of AE. To resolve the current lack of standardization of the assessment of clinical signs of AE, we followed a structured process of systematic reviews and international consensus sessions to identify 1 core outcome measurement instrument for assessment of clinical signs in all future AE trials. Systematic reviews indicated that from 16 different instruments identified to assess clinical signs of AE, only the Eczema Area and Severity Index (EASI) and the objective Scoring Atopic Dermatitis (SCORAD) index were identified as extensively validated. The EASI has adequate validity, responsiveness, internal consistency, and intraobserver reliability. The objective SCORAD index has adequate validity, responsiveness, and interobserver reliability but unclear intraobserver reliability to measure clinical signs of AE. In an international consensus study, patients, physicians, nurses, methodologists, and pharmaceutical industry representatives agreed that the EASI is the preferred core instrument to measure clinical signs in all future AE trials. All stakeholders involved in designing, reporting, and using clinical trials on AE are asked to comply with this consensus to enable better evidence-based decision making, clearer scientific communication, and improved patient care.

Viewing a humorous film decreases IgE production by seminal B cells from patients with atopic eczema.

PubMed

Kimata, Hajime

2009-02-01

Sperms induced IgE production by seminal B cells from patients with atopic eczema via interaction of B cells with galectin-3 on sperms. We studied the effect of viewing a humorous film on IgE production by seminal B cells cultured with sperms. Twenty-four male patients with atopic eczema viewed a humorous film (Modern Times, featuring Charlie Chaplin). Just before and immediately after viewing, semen was collected, and seminal B cells and sperms were purified. Seminal B cells were cultured with sperms and IgE production was measured, while expression of galectin-3 on sperms was assessed. After viewing the humorous film, IgE production by B cells cultured with sperms was significantly decreased. Moreover, expression of galectin-3 on sperms was reduced. Viewing a humorous film reduced galectin-3 expression on sperms, which in turn decreased IgE production by seminal B cells cultured with sperms. These results indicate that viewing a humorous film may be helpful for the study and treatment of local IgE production and allergy in the reproductive tract.

Piercing the earlobes has increased in popularity among males in recent years. This habit would be expected to increase the incidence of nickel and cobalt sensitization. Patch testing with nickel sulfate and cobalt chloride was performed in 520 young Swedish men doing compulsory military service. The overall frequency of nickel/cobalt positive tests was 4.2%. The prevalence of nickel/cobalt positive tests was significantly higher (p < 0.05) in 152 men with pierced earlobes (7.9%) than in those 368 with unpierced earlobes (2.7%). A history of hand eczema (7/152 = 4.6%) or other types of eczema (22/152 = 14.5%) in individuals with pierced earlobes was no more common than in those with unpierced earlobes: 24/368 = 6.5% and 51/386 = 13.9%, respectively (n.s.). Hand eczema was no more common in sensitized (1/22 = 4.5%) than in nonsensitized individuals (32/498 = 6.4%) (n.s.).

Issues related to empirical dietary restriction are important, but they have been inadequately studied among children with atopic dermatitis (AD). To evaluate whether any association exists between food atopy, food avoidance, and AD severity, investigators in the present study reviewed all skin prick tests (SPTs) performed between January 2005 and April 2006 at a pediatric dermatology clinic and correlated findings with history of food avoidance and eczema severity. Only 13% of 114 children with AD had a positive SPT for beef. The most commonly sensitized foods were egg yolk (53%), egg white (42%), shrimp (35%), peanuts (31%), and crab (29%). Disease severity was not associated with prevalence of sensitization to these foods. The investigators concluded that immediate immunoglobulin E reaction to beef, as suggested by positive SPT findings, is unlikely to occur in most children with AD. SPT information may be useful in reassuring parents about the unlikelihood of a severe and immediate reaction to beef. As for other foods, it is sensible to advise parents about specific avoidance strategies only in more severely affected children with a definite history of eczema exacerbation by specific food allergens.

Decreased natural killer cell activity in atopic eczema.

Hall, T J; Rycroft, R; Brostoff, J

1985-01-01

We have studied NK cell activity in atopic and non-atopic subjects using a standard 51Cr-release assay and K562 target cells. In atopics (AT) with allergic rhinitis and/or asthma, NK cell activity was similar to that in non-atopic (N) subjects, whilst patients with severe atopic eczema (AE) had depressed NK cell activity compared to AT or N subjects. In addition, circulating T-cell numbers and Con A responsiveness was decreased in AE, although neither parameter was correlated with decreased NK cell activity. However, decreased NK cell activity in atopic eczema was positively correlated with decreased numbers of Fc gamma + lymphocytes (P = 0.01) and decreased effector: target cell binding (P = 0.05), and negatively correlated with increased monocytes in AE (P = 0.09). AE NK cell activity was equally or more sensitive to the inhibitory effects of drugs such as dibutyryl cyclic AMP, prostaglandins (PG) D2,E2 and histamine. The relative percentage increase in NK cell activity by the interferon inducer poly I:C was similar in AE patients and controls. The results suggest that reduced numbers of circulating NK cells and pre-NK cells account for the depressed level of NK cell activity in subjects with severe atopic eczema. PMID:3876984

Atopic eczema (AE) in the elderly is gradually increasing and has been added to the classification of AE in recent years. This investigation retrospectively analyzed 60 patients with elderly AE. Among the clinical characteristics, a male predominance, existence of several patterns of onset and clinical course, and associations with immunoglobulin (Ig)E-allergic-status and asthmatic complication were observed. The highest positive-rate and positive-score for serum-specific IgE against Dermatophagoides farinae were 83.8% and 2.65 in patients with IgE-allergic AE, and a lower incidence of lichenified eczema in the elbow and knee folds were observed. In terms of treatments and outcomes, clinical improvement and clinical remission were observed in 80.8% and 36.5% of cases, respectively, using standard treatments and combined therapy with oral corticosteroid in severe cases. As for complications and final prognosis, most elderly AE patients reached the end of life with AE, but patients with IgE-allergic AE showed significantly lower incidences of complications of malignancy and death from malignancy. These results indicate that AE in the elderly represents a new subgroup of AE with specific features.

Summary This report provides a summary of the third meeting of the Harmonising Outcome Measures for Eczema (HOME) initiative held in San Diego, CA, U.S.A., 6–7 April 2013 (HOME III). The meeting addressed the four domains that had previously been agreed should be measured in every eczema clinical trial: clinical signs, patient-reported symptoms, long-term control and quality of life. Formal presentations and nominal group techniques were used at this working meeting, attended by 56 voting participants (31 of whom were dermatologists). Significant progress was made on the domain of clinical signs. Without reference to any named scales, it was agreed that the intensity and extent of erythema, excoriation, oedema/papulation and lichenification should be included in the core outcome measure for the scale to have content validity. The group then discussed a systematic review of all scales measuring the clinical signs of eczema and their measurement properties, followed by a consensus vote on which scale to recommend for inclusion in the core outcome set. Research into the remaining three domains was presented, followed by discussions. The symptoms group and quality of life groups need to systematically identify all available tools and rate the quality of the tools. A definition of long-term control is needed before progress can be made towards recommending a core outcome measure. What's already known about this topic? Many different scales have been used to measure eczema, making it difficult to compare trials in meta-analyses and hampering improvements in clinical practice. HOME core outcome measures must pass the OMERACT (Outcome Measures in Rheumatology) filter of truth (validity), discrimination (sensitivity to change and responsiveness) and feasibility (ease of use, costs, time to perform and interpret). It has been previously agreed as part of the consensus process that four domains should be measured by the core outcomes: clinical signs, patient-reported symptoms, long-term control and health-related quality of life. What does this study add? Progress was made towards developing a core outcome set for measuring eczema in clinical trials. The group established the essential items to be included in the outcome measure for the clinical signs of eczema and was able to recommend a scale for the core set. The remaining three domains of patient-reported symptoms, long-term control and health-related quality of life require further work and meetings to determine the core outcome measures. PMID:24980543

Atopic eczema (AE) is a common relapsing inflammatory skin disease in children associated with chronicity and poor quality of life. Many children also display depressive, anxiety and stress symptoms. To investigate the prevalence of depressive, anxiety and stress symptoms, and if these symptoms are associated with disease severity, quality of life and skin biophysiology in childhood AE. Psychological symptoms, eczema severity, quality of life and biophysical skin condition of consecutive adolescents at the pediatric dermatology clinic of a teaching hospital were evaluated with the validated Chinese versions of Depressive, Anxiety, Stress Scales (DASS-42), Beck Depression Inventory (BDI-13), Nottingham Eczema Severity Score (NESS), Children's Dermatology Life Quality Index (CDLQI), transepidermal water loss (TEWL) and stratum corneum skin hydration (SH), respectively. AE patients (n=120) had lower SH, higher TEWL, worse CDLQI and reported higher overall, depressive and stress symptom scores, personal history of atopy, current topical corticosteroid usage and food avoidance than non-AE patients (n=26). Depressive, anxiety and stress symptoms were reported in 21%, 33% and 23% of AE patients, respectively. Multivariate analyses showed that these symptoms were significantly correlated with a poor quality of life (partial correlations of 0.40-0.49; p<0.001). Male patients had more severe disease (higher NESS, p=0.036) and DASS-depressive symptoms (multivariate OR=3.2, p=0.034) than females. Patients who reported current topical steroid usage generally practiced food avoidance (p=0.047), had poor quality of life (p=0.043) but less DASS-depression (multivariate OR=0.354, p=0.043). Only 6% of the 120 AE patients reported prior psychology consultation. Quality of life impairments correlate with disease severity, aberrant skin biophysiology, depression, anxiety and stress symptoms in adolescents with AE. Physicians caring for these patients must evaluate the different but inter-correlated medical, biophysiological and pertinent psychosocial domains. These significant correlations imply that a holistic approach should encompass psychotherapy, behavioral therapy and coping strategies in conjunction with dermatologic therapy.

Development and validation of a questionnaire on 'Satisfaction with dermatological treatment of hand eczema' (DermaSat)

PubMed Central

2010-01-01

Objective To develop a self-administered short questionnaire to assess patient satisfaction with medical treatment for hand eczema (dermatitis) with good psychometric properties. Method The content of the questionnaire was determined on the basis of clinical consultation with groups of patients, from studying the existing instruments, and from discussions with a panel of seven experts. A first draft version containing 38 items organised in six dimensions was tested on a pilot sample of patients to assess its legibility. The extended version was then tested on a sample of 217 patients of both genders enrolled at 18 hospitals representative of the national distribution. The questionnaire was supplied together with the Morisky-Green compliance questionnaire, the health-related quality of life (HRQL) SF-12 questionnaire, and a visual analogue scale (VAS) of perceived health status to assess concurrent validity. The dimensionality was reduced by means of exploratory factor analysis, and reliability was evaluated on the basis of internal consistency and two halves reliability estimates. Item discriminant capability and questionnaire discriminant validity with respect to known groups of patients (by gender, principal diagnosis, age, disease severity and treatment) were also assessed. Results The reduction and validation sample was composed of 54% women and 46% men, of various educational levels with an average age of 43 years (SD = 13.7). Of those who responded, 26% were diagnosed with hyperkeratotic dermatitis of the palms and 27% of the fingertips, and 47% with recurring palmar dyshidrotic eczema. The questionnaire was shortened to a version containing 17 items grouped in six dimensions: effectiveness, convenience, impact on HRQL, medical follow-up, side effects, and general opinion. Cronbach's alpha coefficient reached a value of 0.9. The dimensions showed different degrees of correlation, and the scores had a normal distribution with an average of 58.4 points (SD = 18.01). Treatment satisfaction scores attained correlations between 0.003 and 0.222 with the HRQL measures, and showed higher correlations with the effectiveness (r = 0.41) and tolerability (0.22) measures, but very low correlation with compliance (r = 0.015). Significant differences were observed between some diagnoses and treatments. Conclusions The shortened questionnaire proved to have good psychometric properties, providing excellent reliability, satisfactorily reproducing the proposed structure and supplying evidence of validity.

Background Allergic sensitization and filaggrin gene (FLG) variants are important risk factors for allergic disorders; however, knowledge on their individual and interactive effects on the coexistence of eczema, asthma, and rhinitis is lacking. Objective This study aimed at investigating the single and combined effects of allergic sensitization and FLG variants on the development of single and multiple allergic disorders. Methods The Isle of Wight Birth Cohort (n = 1,456) has been examined at 1, 2, 4, 10, and 18 years of age. Repeated measurements of eczema, asthma, rhinitis, and skin prick tests were available for all follow-ups. FLG variants were genotyped in 1,150 participants. Associations of allergic sensitization and FLG variants with single and multiple allergic disorders were tested in log-binomial regression analysis. Results The prevalence of eczema-, asthma-, and rhinitis-only ranged from 5.6% to 8.5%, 4.9% to 10.2%, and 2.5% to 20.4%, respectively, during the first 18 years of life. The coexistence of allergic disorders is common, with approximately 2% of the population reporting the comorbidity of “eczema, asthma, and rhinitis” during the study period. In repeated measurement analyses, allergic sensitization and FLG variants, when analyzed separately, were associated with having single and multiple allergic disorders. Of particular significance, their combined effect increased the risk of “eczema and asthma” (RR = 13.67, 95% CI: 7.35 – 25.42), “asthma and rhinitis” (RR = 7.46, 95% CI: 5.07 – 10.98), and “eczema, asthma, and rhinitis” (RR = 23.44, 95% CI: 12.27 – 44.78). Conclusions and Clinical Relevance The coexistence of allergic disorders is frequent and allergic sensitization and FLG variants jointly increased risk of allergic comorbidities, which may represent more severe and complex clinical phenotypes. The interactive effect and the elevated proportion of allergic comorbidities associated with allergic sensitization and FLG variants emphasize their joint importance in the pathogenesis of allergic disorders.

Allergy-like symptoms are common in young children, but the case history and physical examination cannot identify the underlying origins of overlapping symptom profiles. To evaluate a blood test, Phadiatop Infant (Pharmacia Diagnostics AB, Uppsala, Sweden), for differentiating the capability of IgE-mediated disease in young children with recurrent wheezing, eczema, or both. One hundred forty-seven children (mean age, 2.0 years) were consecutively referred to 2 allergy centers by their primary care physician for recurrent wheezing, eczema, or both. The allergist's clinical evaluation included medical history, physical examination, skin prick testing with inhalant and food allergens, and specific IgE determinations in blood. The accuracy of Phadiatop Infant was evaluated in a masked manner against the allergist's final diagnosis. Sixty-nine children had wheezing, 69 had eczema, and 9 had both symptoms. Sixty-one children were clinically diagnosed as having IgE-mediated allergy, 78 as having non-IgE-associated disease, and 8 as having an inconclusive diagnosis. Fifty-six of the 61 children with IgE-mediated allergy had positive Phadiatop Infant test results, and 64 of 78 without the condition had negative results. Sensitivity was 92% and specificity was 82%, with positive and negative predictive values of 80% and 93%, respectively. Thirteen children with a positive Phadiatop Infant test result and a negative final diagnosis were retested after 2 years; 12 of them were diagnosed as having IgE-mediated allergy using a masked evaluation. The Phadiatop Infant blood test discriminates between IgE- and non-IgE-mediated symptoms in children younger than 4 years.

Infant feeding and the development of food allergies and atopic eczema: An update.

There is an increasing awareness of food allergies in the community. Dermatologists frequently see patients with atopic eczema, where parents are extremely concerned about the role of food allergy. Advice given to parents regarding the timing of introduction of solid foods has changed markedly over the past decade. Whereas previous advice advocated delaying the introduction of solid foods until the infant's gastrointestinal system had matured, recent studies suggest that the introduction of solids from around 4 to 6 months may actually prevent the development of allergies. Studies on maternal dietary restrictions during pregnancy and lactation have led researchers to believe that antigen avoidance does not play a significant role in the prevention of atopic disease. Breastfeeding exclusively for 4 to 6 months has multiple benefits for mother and child, however, it does not convincingly prevent food allergies or decrease atopic eczema. New evidence suggests that the use of hydrolysed formulas does not delay or prevent atopic eczema or food allergy. This article aims to highlight current evidence and provide an update for dermatologists on the role of food exposure in the development of atopic disease, namely atopic eczema. © 2012 The Authors.

Symptoms have been identified as a core outcome domain for atopic eczema (AE) trials. Various instruments exist to measure symptoms in AE, but they vary in quality and there is a lack of standardization between clinical trials. Our objective was to systematically evaluate the quality of the evidence on the measurement properties of AE symptom instruments, thereby informing consensus discussions within the Harmonising Outcome Measures for Eczema (HOME) initiative regarding the most appropriate instruments for the core outcome domain symptoms. Using the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) checklist and predefined criteria for good measurement properties on identified development and validation studies of AE symptom instruments, a best evidence synthesis was performed to draw an overall conclusion on quality of the instruments and to provide recommendations. Eighteen instruments were identified and evaluated. When the quality and results of the studies were considered, only five of these instruments had sufficient validation data to consider them for the core outcome set for the core outcome domain symptoms. These were the paediatric Itch Severity Scale (ISS), Patient-Oriented Eczema Measure (POEM), Patient-Oriented SCOring Atopic Dermatitis (PO-SCORAD), Self-Administered Eczema Area and Severity Index (SA-EASI) and adapted SA-EASI. ISS (paediatric version), POEM, PO-SCORAD, SA-EASI and adapted SA-EASI are currently the most appropriate instruments and therefore have the potential to be recommended as core symptom instrument in future clinical trials. These findings will be utilized for the development of a core outcome set for AE. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Quality of life (QoL) is one of the core outcome domains identified by the Harmonising Outcome Measures for Eczema (HOME) initiative to be assessed in every eczema trial. There is uncertainty about the most appropriate QoL instrument to measure this domain in infants, children and adolescents. To systematically evaluate the measurement properties of existing measurement instruments developed and/or validated for the measurement of QoL in infants, children and adolescents with eczema. A systematic literature search in PubMed and Embase, complemented by a thorough hand search of reference lists, retrieved studies on measurement properties of eczema QoL instruments for infants, children and adolescents. For all eligible studies, we judged the adequacy of the measurement properties and the methodological study quality with the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) checklist. Results from different studies were summarized in a best-evidence synthesis and formed the basis to assign four degrees of recommendation. Seventeen articles, three of which were found by hand search, were included. These 17 articles reported on 24 instruments. No instrument can be recommended for use in all eczema trials because none fulfilled all required adequacy criteria. With adequate internal consistency, reliability and hypothesis testing, the U.S. version of the Childhood Atopic Dermatitis Impact Scale (CADIS), a proxy-reported instrument, has the potential to be recommended depending on the results of further validation studies. All other instruments, including all self-reported ones, lacked significant validation data. Currently, no QoL instrument for infants, children and adolescents with eczema can be highly recommended. Future validation research should primarily focus on the CADIS, but also attempt to broaden the evidence base for the validity of self-reported instruments. © 2016 British Association of Dermatologists.

Nickel is knows as the most common cause of allergic contact dermatitis, as well as diffuse eczema, allergic rhinitis and bronchial asthma. The mechanism of contact allergy to nickel is well known. In spite of numerous investigations, the mechanism of systemic allergy to nickel is still not clear. 22 patients with positive patch tests to nickel were analyzed. On basis of clinical symptoms the patients were divided into two groups: 1. with contact allergy dermatitis to nickel--8 patients 2. with systemic allergy to nickel (allergic rhinitis and/or diffuse eczema--14 patients. The control group included non-atopic patients with negative patch test to nickel--6 patients. 10 ml of blood were taken from each patient and peripheral mononuclear blood cells (PMBC) were isolated. In PBMC culture, NiSO4 and PHA were stimulated. The control group was non-stimulated cells. The supernatants were collected after 3 and 6 days of culture and the levels of cytokines IL-5, 4 and IFNgamma were measured (ELISA). The concentration of IFNgamma in supernatants from stimulated as well as non-stimulated cells from patients with contact allergy to nickel was higher in comparison to the control group. The concentration of IL-5 in this group was low. There was an increase in the production of IFNgamma and IL-5 after NiSO4 stimulation in patients with systemic allergy to nickel. The higher concentration of IFNgamma in the same groups of patients investigated was in supernatants from the third day of PBMC culture were compared to the sixth day. After 3 and 6 days of culture, the concentration of IL-4 (ELISA) was below detection level in all supernatants analyzed. IFNgamma plays an essential role in the mechanism of developing of contact allergy to nickel; and IFNgamma as well as IL-5 play a role in the mechanism of developing systemic allergy to nickel. The third day of PBMC culture is more reliable for IFNgamma estimation.

A nineteen year old female with pustular eczema and dissociative spells is presented. The patient has a three year history of severe dermatitis beginning shortly after her marriage. Central dynamic issues appear to be difficulty separating from her mother and an ambivalent identification with a hostile father. The patient also describes fugue-like episodes which occur with emerging aggressive feelings. Psychological testing supported these hypotheses. The relevant literature describing the correlation between aggression and skin disease is reviewed. A final uniform formulation was tentatively proposed that this patient, in addition to a strong genetic component for atopic dermatitis, had her illness abetted by inability to cope with aggressive affects.

Loss-of-function mutations in the filaggrin gene (FLG) are associated with xerosis, atopic dermatitis, and early onset of hand eczema. Irritant exposure is a risk factor for occupational hand eczema, and FLG mutations increase the risk of occupational irritant contact dermatitis on the hands in hospital cohorts. It is unknown whether FLG mutations affect the level of irritant exposure. To evaluate whether exposure to occupational irritants was dependent on FLG mutations, atopic dermatitis, and age at hand eczema onset. Randomly chosen Danish adults completed a questionnaire on general health and occupational exposures. Genotyping for FLG mutations (R501X, 2282del4, and R2447X) and patch testing were performed. Overall, 38.7% of subjects reported present or previous occupational exposure to irritants. Among individuals who reported hand eczema onset before entering their work life, 50.6% (45/89) of FLG non-mutation carriers became exposed to irritants, as compared with 28.6% (4/14) of heterozygous and 0% (0/6) of homozygous mutation carriers (p = 0.006). Avoidance was conspicuous among mutation carriers reporting childhood hand eczema and atopic dermatitis (odds ratio 0.08, 95% confidence interval 0.01-0.65). Carriers of FLG mutations who have had hand eczema onset in childhood avoid occupational exposure to irritants; the association is most marked with homozygous mutation status combined with atopic dermatitis. © 2013 John Wiley & Sons A/S.

Aim To conduct a systematic review of treatments for anal eczema (AE). Methods We conducted a Medline search for clinical trial data for the treatment of perianal diseases including AE, including papers not published in the English language. We assessed the study reports using the system recommended by the Oxford Centre for Evidence-based Medicine. No meta-analysis was attempted. Results The evidence base for topical treatments used to treat AE is very poor: there are very few studies and many of those that exist are of poor quality. The best evidence was found for medications that are yet to be licensed for AE. Among products with existing licences for the treatment of eczema, our assessment found some evidence to support the continued use of mild-to-moderate corticosteroids first line in most patients. Discussion Features of the perianal region, and the fact that it is almost always occluded, mean that not all medications recommended in the general treatment guidelines for eczema are appropriate for AE. However, there are no specific treatment guidelines for these patients. This may in part be because of the lack of high-quality evidence-based medicine in this therapy area. Many frequently prescribed medications were developed and licensed many years ago, in an era when clinical trial design was not expected to be as rigorous as it is today. Conclusion This review highlights the need to conduct more high-quality clinical trials in patients with AE in order that specific guidelines for the management of this difficult proctological condition can be prepared.

Background Formaldehyde (FA) and other volatile organic compounds (VOCs) are considered among the main causes of atopic aggravation. Their main sources include wallpapers, paints, adhesives, and flooring materials. Objective To assess the effects of environmentally friendly wallpaper and flooring material on indoor air quality and atopic dermatitis severity. Methods Thirty patients with atopic dermatitis were enrolled in this study. To improve air quality, the wallpaper and flooring in the homes of the subjects were replaced with plant- or silica-based materials. The indoor air concentration of FA and the total VOCs (TVOCs) were measured before remodeling and 2, 6, and 10 weeks thereafter. Pruritus and the severity of atopic eczema were evaluated by using a questionnaire and the eczema area and severity index (EASI) score before and at 4, 8, and 12 weeks after remodeling. The subjects were instructed to continue their therapy for atopic dermatitis. Results The houses of 24 subjects were remodeled; all subjects completed the study. The concentration of FA in ambient air significantly decreased within 2 weeks after remodeling. The TVOC level showed a decrease at week 2 but increased again at weeks 6 and 10. The reduction of pruritus and EASI score was statistically significant in patients whose baseline EASI score was >3. Conclusion Replacing the wallpaper and flooring of houses with environmentally friendly material reduced FA in ambient air and improved pruritus and the severity of atopic eczema. The improvement of pruritus and eczema was statistically significant in patients whose baseline EASI score was >3. PMID:25473219

Improved emollient use reduces atopic eczema symptoms and is cost neutral in infants: before-and-after evaluation of a multifaceted educational support programme

PubMed Central

2013-01-01

Background Parents and carers of children with eczema often underuse emollient therapy, essential to repairing and protecting the defective skin barrier in atopic eczema. Educational interventions delivered by specialist dermatology nurses in hospital settings have been shown to improve emollient use and reduce symptoms of atopic eczema, but benefits of community-based interventions are uncertain. Support and information about appropriate care may often be inadequate for patients and carers in the community. Methods A multifaceted educational support programme was evaluated as a method of increasing emollient use and reducing atopic eczema in children. Support provided for parents and carers included an educational DVD, online daily diary and telephone helpline. The before and after study included 136 British children and their parents, providing baseline and 12 week follow-up data while receiving the programme. Measures included emollient use, POEM and PEST scores, and cost of care. Results Average emollient use increased by 87.6 g (95% CI: 81.9 to 119.5 g, p = 0.001) from baseline with the change being immediate and persistent. The POEM score reduced on average by 5.38 (95% CI: 4.36 to 6.41, p = 0.001), a 47% reduction from baseline. Similarly the PEST score reduced on average by 0.61 (95% CI: 0.47 to 0.75, p = 0.001), a 48% reduction from baseline. Sleep disturbance was reduced by 1.27 nights per week (95% CI: 0.85 to 1.68, p = 0.001) and parental feeling of control improved by 1.32 points (95% CI: 1.16 to 1.48, p = 0.001). From the NHS perspective, the programme was cost neutral overall within the study period. Conclusion A community-based multifaceted educational support programme greatly increased emollient use, reducing symptoms of atopic eczema and general practitioner contacts, without increasing cost. Significant benefits may accrue to the families and carers of children with atopic eczema due to improved sleep patterns and greater feeling of control. PEST, a new simple measure of acute and remitting atopic eczema severity designed to help parents and children to monitor and manage eczema, merits further evaluation. PMID:23679991

[Type IV contact allergies in the food processing industry: an update].

Bauer, A; Schubert, S; Geier, J; Mahler, V

2018-06-01

The food sector is one of the high-risk areas for occupational irritative and allergic contact eczema. The present work provides an overview of the main allergens as well as sensitization frequencies and risk in various food industry occupations. The literature on type IV sensitization in the food sector is summarized. The relative risk of developing a work-related eczema in food processing is increased by more than 3 times. The comparison group was calculated on the basis of the proportion of documented cases in the IVDK (Informationsverbund Dermatologischer Kliniken) network per 100,000 working persons in relation to the average of the years 2005 and 2010. For this purpose, the average risk of all patients was set as reference to 1. Bakers, pastry chefs, cooks and meat and fish processors are mainly affected. In addition to irritant contact eczema, allergic contact eczema and protein contact dermatitis often occur. Leading haptens (main allergens) are rubber ingredients, but also disinfectants and compositae. Only a few contact allergens are responsible for the majority of job-relevant sensitizations in the food industry.

Adverse reactions to foods.

Allergic reactions to foods represent a prominent, actual and increasing problem in clinical medicine. Symptoms of food allergy comprise skin reactions (urticaria, angioedema, eczema) respiratory (bronchoconstriction, rhinitis), gastrointestinal (cramping, diarrhea) and cardiovascular symptoms with the maximal manifestation of anaphylactic shock. They can be elicited by minute amounts of allergens. The diagnosis of food allergy is done by history, skin test, in vitro allergy diagnosis and--if necessary--oral provocation tests, if possible placebo-controlled. Avoidance of respective allergens for the allergic patient, however, is often complicated or impossible due to deficits in declaration regulations in many countries. Increasing numbers of cases including fatalities, due to inadvertent intake of food allergens are reported. It is therefore necessary to improve declaration laws and develop methods for allergen detection in foods. Allergens can be detected by serological methods (enzyme immunoassays, in vitro basophil histamine release or in vivo skin test procedures in sensitized individuals). The problem of diagnosis of food allergy is further complicated by cross-reactivity between allergens in foods and aeroallergens (pollen, animal epithelia, latex etc.). Elicitors of pseudo-allergic reactions with similar clinical symptomatology comprise low-molecular-mass chemicals (preservatives, colorings, flavor substances etc.). For some of them (e.g. sulfites) detection assays are available. In some patients classic allergic contact eczema can be elicited systemically after oral intake of low-molecular-mass contact allergens such as nickel sulfate or flavorings such as vanillin in foods. The role of xenobiotic components in foods (e.g. pesticides) is not known at the moment. In order to improve the situation of the food allergic patient, research programs to elucidate the pathophysiology and improve allergen detection strategies have to be implemented together with reinforced declaration regulations on a quantitative basis.

Contact eczema to foods, spices, and food additives can occur in occupational and nonoccupational settings in those who grow, handle, prepare, or cook food. Pizza is one of the most eaten foods in every continent, and pizza making is a common work in many countries. We aimed to evaluate the occurrence and the causes of contact dermatitis in pizza makers in Naples. We performed an observational study in 45 pizza makers: all the enrolled subjects had to answer a questionnaire designed to detect personal history of respiratory or cutaneous allergy, atopy; work characteristics and timing were also investigated. Every subject attended the dermatology clinic for a complete skin examination, and when needed, patients were patch tested using the Italian baseline series of haptens integrated with an arbitrary pizza makers series. Our results reported that 13.3% of the enrolled pizza makers (6/45) presented hand eczema, and that 8.9% (4/45) were affected by occupational allergic contact dermatitis. Diallyl disulfide and ammonium persulfate were the responsible substances. Performing patch tests in pizza makers and food handlers affected by hand contact dermatitis is useful. We propose a specific series of haptens for this wide working category.

Cheilitis is a superficial inflammatory condition of the lip. It can occur either alone or be associated with stomatitis or perioral eczema. Contact hypersensitivity reactions are a frequent cause of cheilitis. Cosmetic and hygiene products are the most usual causes. Less frequently, allergic cheilitis is caused by contact with musical instruments, topical medicines or food allergens. Cases of cheilitis induced by dental material are rare and debated. The diagnosis relies on patch tests, which start with the European baseline series and the patient's personal cosmetic and topical products. This investigation will then be completed by the ingredients in the topical products and specific test series.

Quantification of quality of life (QoL) related to disease severity is important in patients with atopic eczema (AE), because the assessment provides additional information to the traditional objective clinical scoring systems. To measure health-related QoL (HRQoL) in patients with AE; to analyse discriminant, divergent and convergent validity by examining the association between various QoL methods; and to examine the association between disease severity assessed by an objective Severity Scoring of Atopic Dermatitis (SCORAD) and QoL. HRQoL was assessed at two visits at a 6-monthly interval in 101 patients with AE and 30 controls with one dermatology-specific questionnaire [Dermatology Life Quality Index (DLQI) or Children's DLQI (CDLQI)], one generic instrument (SF-36) and three visual analogue scales (VASs) of severity and pruritus. Objective SCORAD was used to measure disease severity. Patients with AE had significantly lower QoL than healthy controls and the general population. DLQI /CDLQI, pruritus, and patient and investigator overall assessment of eczema severity were significantly (P < 0.0001) and positively correlated with SCORAD, while the generic questionnaire showed only poor correlation. A gender difference was found for the mental component score of SF-36 (P = 0.019). AE has an impact on HRQoL. Patients' mental health, social functioning and role emotional functioning seem to be more affected than physical functioning. A simple VAS score of patients' assessment of disease severity showed the highest and most significant correlations with most of the HRQoL methods used. There is evidence to support the ability of patients with AE to make an accurate determination of their disease severity and QoL.

EMB6/481: Evidence-Based Patient Education on the Web: Methods and studies for determining consumers' needs

Introduction On the Internet, thousands of medical Web sites aim to educate consumers in the field of health. The quality of the educational material for patients varies greatly and is rarely "evidence-based" - not only in terms of the scientific accuracy but also in terms of sometimes questionable appropriateness for the target group. Material boring the reader with facts already known to him/her and failing to address common questions or misunderstandings will most likely fail to reach its aims. Conventional studies to determine the information needs of patients and their relatives are expensive and difficult to conduct. At our dermatology portal site we conducted two separate studies using two different approaches to determine the "needs" of the consumers by using both most commonly used "feedback channels" the Internet has to offer: Emails and Web forms. Methods In the first study, we systematically reviewed 209 unsolicited emails we received from consumers in response to our dermatology Web site, analyzing their contents in respect to previous contacts with live physicians, disease duration, level of frustration expressed in the e-mails, and type of information sought. In another study, we developed a web-based questionnaire as a "pre-test" to determine the knowledge level of patients visiting a patient education site on atopic eczema. The "pre-test" is a form-based "quiz", users are asked to voluntarily complete this questionnaire before entering the information system. The quiz contains 24 statements about atopic eczema, which the user should mark as "true" or "untrue". Once completed, answers are stored in a database and the system generates a dynamic, customized page for the user with explanations and hyperlinks to the respective Web pages which contain further information about the respective items. Results Analysis of the 209 emails revealed that many dermatologic patients surfing the Internet and requesting tele-advice have a chronic disease (81%) and seek a second opinion. Seventeen percent express frustration about previous encounters with live physicians. 40% of all e-mails could have been answered by a librarian. In at least 5 instances patients attempt self-diagnosis. Analysis of 1010 responses to the quiz, entered within 5 months (27.2.-27.7.98), revealed some common misunderstandings among patients with atopic eczema, for example that it is a psychosomatic disease or "disease of the nerves", that a special diet is principally required and that AE is an allergy (which is an especially common misunderstanding among parents!). Discussion The studies demonstrate how easy, fast and cost-effectively the information needs of patients and consumers can be determined using interactive venues on the Internet and give some insights into the motivation of consumers to consult the Internet.

Contact allergy: an update.

Contact allergies are common cause of eczema in all age groups and are one of the most common causes of occupational disability. Contact dermatitis (CD) can be divided into irritant and allergic contact dermatitis. Distinguishing between irritant and allergic triggers of CD by clinical and histologic examinations can be challenging. The approach to patients with CD should consist of a detailed (work and leisure) history, skin examination, patch tests with allergens based on history, physical examination, education on materials that contain the allergen and adequate therapy and prevention.

Increase in dermcidin-derived peptides in sweat of patients with atopic eczema caused by a humorous video.

Dermcidin (DCD)-derived peptide is an antimicrobial peptide produced by the sweat glands. However, the levels of DCD-derived peptide in sweat were decreased in patients with atopic eczema (AE). The effect of viewing a humorous video on the levels of DCD-derived peptide was studied. Twenty patients with AE viewed an 87-min humorous video (Modern Times, featuring Charlie Chaplin). Just before and immediately after viewing, sweat was collected, and the levels of DCD-derived peptide and total protein in sweat were measured. Viewing a humorous video increased the levels of DCD-derived peptide without affecting the levels of total protein in sweat. Viewing a humorous video increased DCD-derived peptide in sweat of patients with AE, and thus, it may be helpful in the treatment of skin infection of AE.

Supporting Self-Care for Families of Children With Eczema With a Web-Based Intervention Plus Health Care Professional Support: Pilot Randomized Controlled Trial

Background Childhood eczema, or childhood atopic dermatitis, causes significant distress to children and their families through sleep disturbance and itch. The main cause of treatment failure is nonuse of prescribed treatments. Objective The objective of this study was to develop and test a Web-based intervention to support families of children with eczema, and to explore whether support from a health care professional (HCP) is necessary to engage participants with the intervention. Methods We followed the PRECEDE-PROCEED model: regular emollient use was the target behavior we were seeking to promote and we identified potential techniques to influence this. LifeGuide software was used to write the intervention website. Carers of children with eczema were invited through primary care mail-out and randomized to 3 groups: (1) website only, (2) website plus HCP support, or (3) usual care. Patient-Oriented Eczema Measure (POEM) scores were measured online by carer report at baseline and at 12 weeks. Qualitative interviews were carried out with 13 HCPs (primarily practice nurses) and 26 participants to explore their experiences of taking part in the study. Results A total of 143 carers were recruited through 31 practices. We found a decrease of ≥2 in follow-up compared with baseline POEM score in 23 of 42 (55%) participants in the website only group, 16 of 49 (33%) in the usual care group, and 18 of 47 (38%) in the website plus HCP group. Website use data showed that 75 of 93 (81%) participants allocated to the website groups completed the core modules, but less than half used other key components (videos: 35%; regular text reminders: 39%). There were no consistent differences in website use between the website only or the website plus HCP groups. Qualitative feedback showed that most HCPs had initial concerns about providing support for eczema self-care because this was not a condition that they felt expert in. However, HCPs reported productive consultations and that they found it helpful to use the website in consultations, while observing that some participants seemed to need more support than others. Qualitative interviews with participants suggested that HCP support was valued highly only by a minority, generally those who were less confident in their management of eczema or less confident using the Internet. Conclusions Our pilot trial demonstrated the potential for greater improvements in POEM scores in both website intervention groups and that a full-scale trial is feasible. Such a trial would quantify the effectiveness and cost-effectiveness of this intervention to determine whether it should be widely promoted to families of children with newly diagnosed eczema. In this study population, HCP support was not strongly valued by participants and did not lead to better outcomes or website use than use of the Web-based intervention alone.

Although "atopic march" is a popular concept, the relationship between eczema and subsequent asthma is far from clear. However, some cohort studies have shown the possibility of two different allergic phenotypes in those who present with early eczema in terms of their persistency. We checked the cohort data from 308,849 children born in 2000 in Taiwan, to evaluate the different courses of eczema and their relationships to subsequent asthma and allergic rhinitis (AR) at age 7 years. We examined the age prevalence of eczema, asthma, and AR up to 7 years of age. We grouped all cases according to their course of eczema, as well as wheezing, and determined the rates of asthma and AR at age 7 years. We checked the adjusted risk factors by multiple logistic regression model. We also examined the distributions of wheezing types in different eczema groups. We found the "atopic march" pattern of allergic diseases based on their age prevalence. Early eczema was associated with asthma and AR at the age of 7 years. Those with eczema symptoms persisting after 36 months of age had a higher risk than those with transient eczema. Early wheeze also contributed to asthma and AR later in childhood. In addition, late-onset eczema had a completely different wheeze distribution compared with other groups and also had a higher risk for asthma and AR than transient eczema. In conclusion, different eczema phenotypes could be found in this population-based cohort. This article emphasizes the special attention to the persistency and late-onset eczema in clinical practice.

Prevalence, incidence and predictive factors for hand eczema in young adults – a follow-up study

2013-01-01

Background Hand eczema is common in the general population and affects women twice as often as men. It is also the most frequent occupational skin disease. The economic consequences are considerable for society and for the affected individuals. Methods To investigate the prevalence and incidence of hand eczema and to evaluate risk factors for development of hand eczema in young adults. Subjects and methods; This is a prospective follow-up study of 2,403 young adults, 16 – 19 years old in 1995 and aged 29 – 32 years, 13 years later, in 2008. They completed a postal questionnaire that included questions regarding one-year prevalence of hand eczema, childhood eczema, asthma, rhino-conjunctivitis and factors considered to affect hand eczema such as hand-washing, washing and cleaning, cooking, taking care of small children and usage of moisturisers. These factors were evaluated with the multinominal logistic regression analysis. Results The one-year prevalence of hand eczema was 15.8% (females 20.3% and males 10.0%, p < 0.001). The incidence was 11.6 cases per 1000 person-years (females 14.3 and males 5.2, p < 0.001). Childhood eczema was the most important risk factor for hand eczema. The odds ratios were 13.17 when having hand eczema 1995 and 2008 compared to 5.17 in 2008 (p < 0.001). A high frequency of hand washing was important in predicting hand eczema only when having 1-year prevalence 2008, OR 1.02 (p = 0.038). Conclusions After 13 years an increased 1-year prevalence of hand eczema was found. The significant risk factors for hand eczema changed over time from endogenous to exogenous factors. PMID:24164871

Several studies show an association between eczema and attention-deficit/hyperactivity disorder (ADHD) in childhood, but the mechanisms and time sequence remain unclear. Information on the association between eczema and other disorders involving the central nervous system (CNS) is limited. The aim was to explore whether preschool eczema was associated with ADHD or other CNS-associated disorders requiring pharmacotherapy at school age and to analyze whether eczema at other ages of childhood was associated with medication for ADHD. From a Swedish birth cohort, 3606 children were included in the analyses. At 1, 2, 4, 8, 12, and 16 years of age, their parents answered questionnaires regarding eczema the last year. Information on prescribed medications during school age (10-18 years of age) was derived by record linkage to the Swedish Prescribed Drug Register. A total of 1178 (32.7%) of the children had preschool eczema (eczema at 1, 2, and/or 4 years), and 162 (4.5%) of the children had dispensed ADHD medication at school age. Preschool eczema was not associated with ADHD medication at school age (crude odds ratio 1.16; 95% Confidence Intervals: 0.83-1.61). There was no significant association between preschool eczema and use of antidepressants, migraine drugs, or anti-epileptics at school age. Infantile eczema, school-age eczema, and eczema ever up to 16 years of age were not associated with ADHD medication at school age. In this large birth cohort, there were no significant associations between preschool eczema and medications for ADHD, depression/anxiety/phobia, migraine, or epilepsy at school age. © 2016 John Wiley & Sons A/S.

Previous knowledge of the impact of certain life-style factors on hand eczema is scanty. To investigate a possible association between hand eczema and life-style factors such as obesity, physical exercise, stress, smoking and alcohol consumption. In a cross-sectional public health survey in Stockholm, Sweden, 27,994 (58%) randomly chosen individuals aged 18-64 years completed a postal questionnaire regarding physical and mental health, social relations, economic status and work. Of these, 27,793 individuals responded to the question regarding hand eczema and were included in the present study. The association between life-style factors and hand eczema was analysed by prevalence proportion ratios (PPR), using a generalized linear model. Hand eczema was more common among individuals who reported high stress levels, PPR 1·326 (95% CI 1·303-1·350). There was also a positive dose-response relationship between hand eczema and stress. Hand eczema was less common among individuals reporting high physical exercise, and most apparent in women, PPR 0·781 (95% CI 0·770-0·792). Men who reported high alcohol intake reported hand eczema less often, PPR 0·958 (95% CI 0·930-0·987). Obese individuals reported hand eczema more commonly, PPR 1·204 (95% CI 1·174-1·234). There was a slight increase of hand eczema among smokers, PPR 1·025 (95% CI 1·006-1·044). Hand eczema was more common in individuals who reported stress, obesity and smoking. In individuals who reported high physical exercise levels hand eczema was less common. As there appears to be an association between life-style factors and hand eczema it is important to consider life-style factors in clinical practice. © 2011 The Authors.

Why am I so itchy?

2004-07-01

Virtually all of us experience an itch at some time. However, for some people, an intense or persistent itch can cause considerable morbidity that often affects the entire family. This article gives an overview of the problem of itch, and discusses the assessment and management of atopic eczema, scabies, lichen planus and dermatitis herpetiformis. A good history will nearly always provide the diagnosis. Examination can then be targeted at finding specific signs. The distribution of rash is important, as is examination of the nails and mouth. Simple but helpful investigations such as microscopy and skin biopsy can be carried out in the consulting room. If a patient presents with a very itchy rash, consider four main possibilities: eczema, scabies, lichen planus and dermatitis herpetiformis, with the first two being the most common. For chronic conditions such as eczema, structured follow up is essential.

To study the psychosocial factors in patient with chronic hand eczema (CHE).
 Methods: Personality traits, emotional state, and quality of life of 240 patients with CHE and 221 normal control (NC) subjects were assessed by General Questionnaire, Eysenck Personality Questionnaire (EPQ), Self-Rating Depression Scale (SDS), Self-Rating Anxiety (SAS), and Eczema Quality of Life Scale (EQOLS).
 Results: In comparison, EPQ scores, scores of extraversion (E) factor in patients with CHE were significantly lower than those in NC subjects (P<0.01), but scores of neuroticism (N) factor in patients with CHE were significantly higher than those in NC subjects (P<0.01), while there was no significant difference in scores of psychoticism (P) and lie (L) factors between two groups (P>0.05). Patients with CHE had significantly higher scores in SDS and SAS compared with the NC subjects (P<0.01). Patients with CHE had significantly higher scores in scale of morbid, physical, social, psychological, general quality of life, and total scores of EQOLS compared with the NC subjects (P<0.01). The level of skin lesions and the degree of itch were significantly correlated with scores in scale SDS, SAS, morbid, physical, social, psychological, general quality of life, and total scores of EQOLS compared with the NC subjects (P<0.05).
 Conclusion: Personality of patients with CHE is prone to emotional instability of introverts.Patients with CHE have a higher level of depression and anxiety, and exert a negative effect on their quality of life, which is related to severity of disease.

2008-09-01

Acne, psoriasis and atopic eczema are common diseases and have been consistently associated with adverse psychological sequelae including stigmatization. Being teased on the basis of appearance has been associated with psychiatric morbidity in children and adolescents. The objective of this qualitative study was to explore the experiences of teasing and bullying in patients with acne, psoriasis and eczema, and the role of appearance-related teasing and bullying as mediators of psychological morbidity in these patients. Data collection consisted of 62 in-depth semi-structured interviews with patients with acne, psoriasis or atopic eczema recruited from both specialist dermatology and general practices. Data analysis was cumulative and concurrent throughout the data collection period reflecting a grounded theory approach. Analysis followed the analytic induction method, allowing themes to emerge from the data. Teasing, taunting or bullying was a considerable problem for a significant minority of acne, psoriasis and atopic eczema participants. Themes that emerged were the universally negative nature of the teasing, the use of teasing as an instrument of social exclusion, and as a means of establishing or enforcing power relationships, teasing related to contagion and fear, the emotional and psychological sequelae of teasing and the theme of 'insensate' teasing. For those who had suffered teasing or bullying, this was causally linked in respondents' accounts with psychological sequelae, especially self-consciousness and effects on self-image and self-esteem. Experiences of teasing and bullying were found to have principally occurred during the adolescence of participants and the perpetrators were other adolescents, but there were findings of respondents with psoriasis also having been subjected to ridicule or derogatory remarks by health professionals. Teasing, taunting and bullying may represent an underappreciated source of psychological morbidity in children and adolescents with these common skin diseases.

The Th1/Th 2 concept is a model to understand the pathophysiology of certain diseases. Atopic diseases (asthma, eczema and hayfever) are characterized by a chronic inflammatory reaction that is dominated by Th 2 cells, and type 1 diabetes mellitus (DM) is Th1 cell dominated. Because it is known that Th1 and Th 2 cells reciprocally counteract each other, it can be speculated that the prevalence of Th 2-mediated disease is lower in patients with Th1-mediated disease. To compare the prevalence of atopic diseases between children with DM and age-matched controls. Parents of children with DM were requested by Dutch paediatricians to complete the International Study of Asthma and Allergies in Childhood (ISAAC) questionnaire on the prevalence of atopic diseases. A control group was derived from a Dutch cross-sectional survey (the ISAAC2 study). We received 555 completed questionnaires, which is estimated to be 25% of the total number of Dutch children with DM. The control group consisted of 777 children. After age-matching, the questionnaires of 188 DM patients were used. Symptoms of asthma, hayfever and eczema were reported less in the group of children with DM compared with the control group (wheeze last year, OR 0.796, 95% CI 0.408-1.554; hayfever symptoms last year, OR 0.642, 95% CI 0.369-1.118; eczema symptoms last year, OR 0.693, 95% CI 0.430-1.115). The lower prevalence of astma, hayfever and eczema symptoms in DM patients compared with age-matched controls, although not statistically significant, is consistent with the Th1/Th 2 concept.

Somatization: the under-recognized factor in nonspecific eczema. The Hordaland Health Study (HUSK).

Psychodermatology has focused primarily on depression and anxiety in eczema. Skin symptoms are listed among many others for the ICD-10 diagnosis of somatization disorder. Somatization (unexplained somatic symptoms) is highly prevalent in the general population, but its association with eczema is yet to be empirically investigated. We therefore explored the association between somatization and eczema by examining the extent of somatization in eczema compared with allergic rhinitis, and by examining if eczema was more strongly associated with somatization than with anxiety and depression. Finally, we aimed to examine the relationship between the site of eczema and somatization for individual somatic symptoms and for somatic symptoms as a whole. For this population-based cross-sectional study we employed data from the Hordaland Health Study (HUSK) with 15,225 participants aged 41-48 years. Information on nonspecific eczema, allergic rhinitis, somatization, anxiety, depression and other covariates was obtained by self-report. The association between nonspecific eczema and somatization was strong and followed a dose-response pattern, as did all somatic symptoms in our index of somatization when analysed separately. The association between nonspecific eczema and somatization was stronger than that between rhinitis and somatization, and also the association between nonspecific eczema and anxiety and depression. In multivariate models, somatization accounted for most of the association between nonspecific eczema and anxiety/depression. In contrast, the association between nonspecific eczema and somatization was robust for adjustment for anxiety/depression. Somatization was strongly associated with nonspecific eczema. This applies to a whole range of somatic symptoms constituting the construct of somatization. There is hardly any mention of somatization in leading dermatological journals, in contrast to anxiety and depression which are frequently reported in eczema. We speculate that this under-recognition of somatization in the dermatological literature may correspond to under-recognition of this factor also in clinical practice. © 2011 The Authors.

Background The Scottish Photobiology Service is the national referral pathway for patients with cutaneous photosensitivity diseases in Scotland. We reviewed the pattern of diagnosis of photosensitivity diseases and investigations performed between 1989 and 2015. Methods and Results Data were collected from the Photodiagnostic Database, annual reports and paper records. The total number of patients assessed each year was stable over the period studied (median 242 [range 231-266]), with most being new patients (median 69 [range 62-73]%). Monochromator phototesting was the most utilised investigation, although the use of provocation testing and photopatch testing has increased. The most common diagnosis was polymorphic light eruption, and there was a trend to increasing diagnosis of photoaggravated atopic eczema. Conclusions The pattern of diagnosis of photosensitivity diseases remains fairly stable in Scotland and we wish to emphasise the importance of this Scottish specialist service for patients with photosensitivity diseases and referrers.

There are few studies on psychosocial problems in adolescents with eczema. We performed a cross-sectional, questionnaire-based study to explore the relationship of suicidal ideation, mental health problems, and social functioning with eczema. A total of 4,744 adolescents (18-19 years) were invited for the study, of whom 3,775 (80%) participated. The overall prevalence of current eczema was 9.7%. Among those with current eczema, 15.5% reported suicidal ideation compared with 9.1% among those without eczema, significantly associated in a multivariate model (odds ratio 1.87, 95% confidence interval 1.31-2.68). In a subgroup analyses, the prevalence of suicidal ideation in those with both eczema and itch was 23.8%, and was significantly associated, compared with those without eczema (3.57, 2.46-5.67). Eczema was associated with mental health problems assessed by the Strength and Difficulties Questionnaire (1.72, 1.21-2.45) and the Hopkins Symptom Checklist 10 (1.63, 1.23-2.16). Five questions assessed social function: feeling attached to family and friends; thriving at school; experiencing bullying; and romantic relationships. Boys with current eczema were less likely to have had romantic relationships (1.93, 1.21-3.08). Eczema in late adolescence is associated with suicidal ideation and mental health problems but rarely with social problems. Our findings point to the importance of addressing mental health issues in adolescents with eczema.

Childhood chronic health conditions have considerable impact on children. We aimed to test the efficacy of a brief, group-based parenting intervention for improving illness-related child behaviour problems, parents' self-efficacy, quality of life, parents' competence with treatment, and symptom severity. A 2 (intervention vs. care as usual) by 3 (baseline, post-intervention, 6-month follow-up) design was used, with random group assignment. Participants were 107 parents of 2- to 10-year-old children with asthma and/or eczema. Parents completed self-report questionnaires, symptom diaries, and home observations were completed. The intervention comprised two 2-h group discussions based on Triple P. Parents in the intervention group reported (i) fewer eczema-related, but not asthma-related, child behaviour problems; (ii) improved self-efficacy for managing eczema, but not asthma; (iii) better quality of life for parent and family, but not child; (iv) no change in parental treatment competence; (v) reduced symptom severity, particularly for children prescribed corticosteroid-based treatments. Results demonstrate the potential for brief parenting interventions to improve childhood chronic illness management, child health outcomes, and family wellbeing. Effects were stronger for eczema-specific outcomes compared to asthma-specific outcomes. Effects on symptom severity are very promising, and further research examining effects on objective disease severity and treatment adherence is warranted. ACTRN12611000558921.

Epidemiological research on the relationship between single nucleotide polymorphisms (SNPs) in the IL4Rα gene and eczema is sparse. We investigated the associations between IL4Rα SNPs rs1805011, rs1805015 and rs1801275 and risk of eczema in young adult Japanese women. Included were 188 women who met the criteria of the International Study of Asthma and Allergies in Childhood (ISAAC) for eczema. Controls were 635 women without eczema according to the ISAAC criteria who also had not been diagnosed with asthma, atopic eczema and/or allergic rhinitis by a doctor. Adjustment was made for age, region of residence, number of children, smoking and education. Under the additive model, SNP rs1805011 was significantly related to eczema: the adjusted OR was 0.55 (95% CI: 0.31-0.99). SNP rs1805015 was significantly associated with eczema in the additive and dominant models: the adjusted ORs were 0.55 (95% CI: 0.30-0.98) and 0.55 (95% CI: 0.30-0.997), respectively. There was no significant association between SNP rs1801275 and eczema. None of the haplotypes were significantly related to eczema. Significant associations between SNPs rs1805011 and rs1805015 and eczema were reported in women who had never smoked, but not in those who had ever smoked; the multiplicative interactions, however, were not significant. This is the first study to demonstrate significant associations between IL4Rα SNPs rs1805011 and rs1805015 and eczema. We do not find evidence for interactions affecting eczema between IL4Rα SNPs and smoking. © 2013 The Authors. Scandinavian Journal of Immunology © 2013 Blackwell Publishing Ltd.

Cross-sectional studies suggest an association between eczema and mental health problems, but the temporal relationship is unclear. To assess the association between infant-onset eczema and mental health problems in a prospective study. Between 1995 and 1998, a birth cohort study was recruited and followed until age 10 years. Physician-diagnosed eczema, comorbidities, and a broad set of environmental exposures were assessed at age 1, 2, 3, 4, 6, and 10 years. First, we investigated the association between infant-onset eczema (age 1-2 years) and mental health problems at age 10 years according to the Strengths and Difficulties Questionnaire. Second, we analyzed the likelihood of mental health problems at age 10 years in relation to the course of eczema. A total of 2916 infants were eligible for analysis. Compared with participants never diagnosed as having eczema, children with infant-onset eczema had a significantly increased risk for possible/probable mental health problems (Strengths and Difficulties Questionnaire total score) at age 10 years (odds ratio, 1.49; 95% CI, 1.13-1.96) and for emotional symptoms (odds ratio, 1.62; 95% CI, 1.25-2.09). Eczema limited to infancy predicted a significantly higher risk for conduct problems at age 10 years. The strength of the association between eczema and emotional problems at age 10 years increased with increasing eczema persistence. Infants with eczema are at increased risk for mental health problems at age 10 years. Even if cleared afterward, eczema at age 1 to 2 years may cause persistent emotional and behavioral difficulties.

In a randomized, controlled trial (RCT) on childhood eczema we reported that substituting nurse practitioners (NPs) for dermatologists resulted in similar outcomes of eczema severity and in the quality of life, and higher patient satisfaction. To determine costs and cost-effectiveness of care provided by NPs vs. dermatologists and to compare our results with those in studies from other countries. We estimated the healthcare costs, family costs and the costs in other sectors alongside the RCT. All the costs were linked to quality of life [Infants' Dermatitis Quality of Life Index (IDQOL), Children's Dermatology Life Quality Index (CDLQI)] and to patient satisfaction (Client Satisfaction Questionnaire-8) to determine the incremental cost-effectiveness ratio (ICER). We also examined all the reported studies on the costs of childhood eczema. The mean annual healthcare costs, family costs and costs in other sectors were €658, €302 and €21, respectively, in the NP group and €801, €608 and €0·93, respectively, in the dermatologist group. The ICER in the NP group compared with the dermatologist group indicated €925 and €751 savings per one point less improvement in IDQOL and CDLQI, respectively, and €251 savings per one point more satisfaction in the NP group at 12 months. The mean annual healthcare costs and family costs varied considerably in the six identified studies. Substituting NPs for dermatologists is both cost-saving and cost-effective. The treatment of choice is that provided by the NPs as it is similarly effective to treatment provided by a dermatologist with a higher parent satisfaction. International comparisons are difficult because the types of costs determined, the units and unit prices, and eczema severity all differ between studies. © 2011 The Authors.

Information about predictive factors of hand eczema is crucial for primary prevention. To investigate predictive factors of hand eczema in adult Danes from the general population. Participants from a cross-sectional 5-year follow-up study in the general population, aged 18-72 years (n = 2270), completed questionnaires about skin health and were grouped into four hand eczema groups: 'never', 'incident', 'nonpersistent' and 'persistent'. Multiple logistic regression models adjusted for age group and sex were used to evaluate associations with baseline variables. The participation rate for the follow-up study was 66·5% (29·7% of the participants originally invited to the baseline study). A history of atopic dermatitis (AD) was associated with both persistent and incident hand eczema [odds ratio (OR) 9·0, 95% confidence interval (95% CI) 5·6-14·4 and OR 3·0, 95% CI 1·7-5·2, respectively]. Thus, even in adulthood, a history of AD should be considered as a predictor of incident hand eczema. While filaggrin gene (FLG) null mutations were not associated with incident hand eczema, a statistically significant association was observed with persistent hand eczema (OR 3·1, 95% CI 1·8-5·2). Finally, contact sensitization (23 allergens without nickel) was also associated with persistent hand eczema (OR 2·5, 95% CI 1·2-5·0), independently of a history of AD. This study confirms a history of AD as the strongest predictor of persistent hand eczema. We additionally found that a history of AD was associated with incident hand eczema in adults, in contrast to FLG mutations, which were associated only with persistent hand eczema in individuals with a history of AD, and not with incident hand eczema. Our study adds new knowledge to the interplay between AD, FLG mutations and hand eczema in the adult general population. © 2016 British Association of Dermatologists.

Occupational hand eczema is common in hairdressers, owing to wet work and hairdressing chemicals. To estimate the prevalence of hand eczema and its career consequences among hairdressers in Denmark. A register-based study was conducted, comprising all graduates from hairdressing vocational schools from 1985 to 2007 (n = 7840). The participants received a self-administered postal questionnaire including questions on hand eczema, atopic dermatitis, and career change. A response rate of 67.9% (n = 5324) was obtained. Of the respondents, 44.3% no longer worked as hairdressers and had worked for an average of 8.4 years in the profession before leaving it. Hand eczema was more common among ex-hairdressers (48.4%) than among current hairdressers (37.6%) (p < 0.0001), and significantly more ex-hairdressers (26.8%) than current hairdressers (15.7%) had chronic hand eczema (p < 0.0001). Of the respondents with hand eczema, 75% were aged 15-24 years at onset, and 45.5% gave hand eczema as a reason for career change. In this group, logistic regression analysis showed that chronic hand eczema contributed the most to the decision to change career (odds ratio 50.12; 95% confidence interval 18.3-137). Hairdressers work an average of 8.4 years in the profession before leaving it, and hand eczema contributes significantly to this career change. © 2011 John Wiley & Sons A/S.

Cutaneous protothecosis is a rare infection caused by achlorophyllic algae of the genus Prototheca. The lesions usually occur on exposed areas, related with trauma, in immunocompromised patients. The most common clinical presentation is a vesicobullous and ulcerative lesion with pustules and scabs, simulating bacterial, fungal or herpetic infections or eczema. The diagnosis is determined by agent identification through histopathology, culture and the carbohydrates assimilation test. The finding of morula-like spherules is characteristic of Prototheca sp. Its rarity and non-specific clinical aspect may difficult the disease diagnosis. We report a case of a diabetic patient, in chronic use of systemic corticosteroids, that developed a skin lesion after trauma to the right leg. PMID:24346914

Summary Staphylococcus aureus skin colonization is universal in atopic dermatitis and common in cancer patients treated with epidermal growth factor receptor inhibitors. However, the causal relationship of dysbiosis and eczema has yet to be clarified. Herein, we demonstrate that Adam17fl/flSox9-Cre mice, generated to model ADAM17-deficiency in human, developed eczematous dermatitis with naturally occurring dysbiosis, similar to that observed in atopic dermatitis. Corynebacterium mastitidis, S. aureus, and Corynebacterium bovis sequentially emerged during the onset of eczematous dermatitis, and antibiotic specific for these bacterial species almost completely reversed dysbiosis and eliminated skin inflammation. Whereas S. aureus prominently drove eczema formation, C. bovis induced robust T helper 2 cell responses. Langerhans cells were required for eliciting immune responses against S. aureus inoculation. These results characterize differential contributions of dysbiotic flora during eczema formation, and highlight the microbiota-host immunity axis as a possible target for future therapeutics in eczematous dermatitis.

2009-11-01

Respiratory symptoms from environmental perfume exposure are main complaints in patients with multiple chemical sensitivities and often coincide with asthma and or eczema. In this population-based twin study we estimate the heritability of respiratory symptoms related to perfume and if co-occurrences of the symptoms in asthma, atopic dermatitis, hand eczema or contact allergy are influenced by environmental or genetic factors common with these diseases. In total 4,128 twin individuals (82%) responded to a questionnaire. The heritability of respiratory symptoms related to perfume is 0.35, 95%CI 0.14-0.54. Significant associations (p<0.05) between perfume-related respiratory symptoms and asthma, atopic dermatitis, hand eczema or contact allergy are not attributable to shared genetic or shared environmental/familial factors, except possibly for atopic dermatitis where genetic pleiotropy with respiratory symptoms to perfume is suggested by an estimated genetic correlation of 0.39, 95%CI 0.09-0.72.

To inform the development of a core outcome set for eczema by engaging with people with eczema and parents of children with eczema to understand their experiences and understanding of the concept 'eczema control'. 37 participants took part in a total of six semi-structured online focus groups held in a typed chatroom with 5-7 participants per group. Three groups involved adults with eczema and three groups involved parents of children with eczema. Framework analysis was used for data analysis. A community-based sample was recruited from across the UK via social media and email. 19 adults aged 17-61 years (15/19 female, 16/19 white) and 18 parents of children with eczema aged 9 months-17 years (9/18 female, 18/19 white). Four main themes were identified:(1) 'Commonalities and differences in the experiences of control': a reduction in symptoms such as itch and sleep loss characterised eczema control, but what level was acceptable differed across participants;(2) 'Eczema control goes beyond the skin': psychological factors, social factors, the constant scratching and the impact on everyday activities are a variety of ways an individual can be impacted;(3) 'Stepping up and down of treatment': participants' stepped-up treatment in response to loss of control, but several factors complicated this behaviour. Control needed to be maintained after stepped-up treatment ended to be acceptable; and (4) 'How to measure control': self-report was generally preferred to allow frequent measurements and to capture unobservable features. Although most thought their eczema needed to be measured frequently, many also felt that this was not always realistic or desirable. 'Eczema control' is a complex experience for people with eczema and parents of children with the condition. These experiences could have important implications on how long-term control should be measured in eczema clinical trials and clinical practice. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

Nummular eczema: An addition of senile xerosis and unique cutaneous reactivities to environmental aeroallergens.

The pathogenesis of nummular eczema (NE) is still unknown. It often develops on the lower legs of elderly individuals with xerotic changes during the winter months. Such winter exacerbation is also observed in atopic dermatitis, in which there is a high incidence of cutaneous immune reactivities against environmental aeroallergens. Because of the total lack of information about skin reactivities in NE patients, we performed immunological as well as functional studies in their uninvolved skin. Prick tests and chamber scarification patch tests for representative aeroallergens were conducted on the flexor surface of the forearm in 26 NE patients, in 21 age-matched elderly persons without NE and in 43 healthy young controls. We found that the elderly subjects, regardless of their background, showed a significantly higher immediate skin reactivity to Candida albicans than the young controls. In contrast, patch testing revealed that, unlike the age-matched elderly subjects who showed a decrease in incidence of positive patch test reactions, the NE patients retained delayed contact sensitivity at a level comparable to that of the young healthy controls. They showed a significantly higher percentage of positive patch test reactions to Dermatophagoides farinae allergen (46%) and house dust allergen (35%) than the age-matched controls. Moreover, they also showed a significantly higher percentage of delayed hypersensitive reactions to C. albicans allergen (85%) than the age-matched controls (48%). Noninvasive functional assessment of the stratum corneum (SC) in unaffected skin areas of the lower legs in 8 NE patients demonstrated that, though the water barrier function of the SC was comparable to that of the age-matched controls, they showed a significantly lower hydration state of the SC than the age-matched controls. The xerotic skin of elderly individuals facilitates the development of cracking and fissuring of the skin surface in dry and cold winter. Such damage in the SC is sometimes aggravated by inadvertent scratching due to pruritus, allowing skin permeation of various environmental allergens. They may induce eczematous changes in those with preserved adequate delayed hypersensitivity despite their advanced age.

Recent studies have suggested that epidermal barrier dysfunction contributes to the development of atopic dermatitis (AD) and other allergic diseases. We performed a prospective, randomized controlled trial to investigate whether protecting the skin barrier with a moisturizer during the neonatal period prevents development of AD and allergic sensitization. An emulsion-type moisturizer was applied daily during the first 32 weeks of life to 59 of 118 neonates at high risk for AD (based on having a parent or sibling with AD) who were enrolled in this study. The onset of AD (eczematous symptoms lasting >4 weeks) and eczema (lasting >2 weeks) was assessed by a dermatology specialist on the basis of the modified Hanifin and Rajka criteria. The primary outcome was the cumulative incidence of AD plus eczema (AD/eczema) at week 32 of life. A secondary outcome, allergic sensitization, was evaluated based on serum levels of allergen-specific IgE determined by using a high-sensitivity allergen microarray of diamond-like carbon-coated chips. Approximately 32% fewer neonates who received the moisturizer had AD/eczema by week 32 than control subjects (P = .012, log-rank test). We did not show a statistically significant effect of emollient on allergic sensitization based on the level of IgE antibody against egg white at 0.34 kUA/L CAP-FEIA equivalents. However, the sensitization rate was significantly higher in infants who had AD/eczema than in those who did not (odds ratio, 2.86; 95% CI, 1.22-6.73). Daily application of moisturizer during the first 32 weeks of life reduces the risk of AD/eczema in infants. Allergic sensitization during this time period is associated with the presence of eczematous skin but not with moisturizer use. Copyright © 2014 The Authors. Published by Elsevier Inc.

Asthma, rhinitis and eczema often co-occur in children, but their interrelationships at the population level have been poorly addressed. We assessed co-occurrence of childhood asthma, rhinitis and eczema using unsupervised statistical techniques. We included 17 209 children at 4 years and 14 585 at 8 years from seven European population-based birth cohorts (MeDALL project). At each age period, children were grouped, using partitioning cluster analysis, according to the distribution of 23 variables covering symptoms 'ever' and 'in the last 12 months', doctor diagnosis, age of onset and treatments of asthma, rhinitis and eczema; immunoglobulin E sensitization; weight; and height. We tested the sensitivity of our estimates to subject and variable selections, and to different statistical approaches, including latent class analysis and self-organizing maps. Two groups were identified as the optimal way to cluster the data at both age periods and in all sensitivity analyses. The first (reference) group at 4 and 8 years (including 70% and 79% of children, respectively) was characterized by a low prevalence of symptoms and sensitization, whereas the second (symptomatic) group exhibited more frequent symptoms and sensitization. Ninety-nine percentage of children with comorbidities (co-occurrence of asthma, rhinitis and/or eczema) were included in the symptomatic group at both ages. The children's characteristics in both groups were consistent in all sensitivity analyses. At 4 and 8 years, at the population level, asthma, rhinitis and eczema can be classified together as an allergic comorbidity cluster. Future research including time-repeated assessments and biological data will help understanding the interrelationships between these diseases. © 2015 John Wiley & Sons A/S.

Household animal dander has been implicated as aeroallergen in childhood atopic diseases. Many parents seek healthcare advice if household pet keeping may be detrimental in atopic eczema (AE), allergic rhinitis and asthma. We investigated if skin sensitization by cat/dog dander was associated with disease severity and quality of life in children with AE. Demographics, skin prick test (SPT) results, disease severity (Nottingham eczema severity score NESS), Children Dermatology Life Quality Index (CDLQI), blood IgE and eosinophil counts of a cohort of AE patients were reviewed. 325 AE patients followed at a pediatric dermatology clinic were evaluated. Personal history of asthma was lowest (20%) in the dog-dander-positive-group but highest (61%) in bothcat- and-dog-dander-positive group (p=0.007). Binomial logistic regression ascertained that catdander sensitization was associated with increasing age (adjusted odds ratio [aOR], 1.056; 95% Confidence Interval [CI], 1.006 to 1.109; p=0.029), dust-mite sensitization (aOR, 4.625; 95% CI, 1.444 to 14.815; p=0.010), food-allergen sensitization (aOR, 2.330; 95% CI, 1.259 to 4.310; p=0.007) and keeping-cat-ever (aOR, 7.325; 95% CI, 1.193 to 44.971; p=0.032); whereas dogdander sensitization was associated with dust-mite sensitization (aOR, 9.091; 95% CI, 1.148 to 71.980; p=0.037), food-allergen sensitization (aOR, 3.568; 95% CI, 1.341 to 9.492; p=0.011) and keeping-dog-ever (aOR, 6.809; 95% CI, 2.179 to 21.281; p=0.001). However, neither cat nor dog sensitization were associated with asthma, allergic rhinitis, parental or sibling atopic status, disease severity or quality of life. Physicians should advise parents that there is no direct correlation between AE severity, quality of life, asthma or allergic rhinitis with cutaneous sensitization to cats or dogs. Sensitized patients especially those with concomitant asthma and severe symptoms may consider non-furry alternatives if they plan to have a pet. Highly sensitized individuals, especially those with asthma co-morbidity, may have to remove their pet for a trial period to determine if symptoms improve.

Reaching clinically relevant outcome measures for new pharmacotherapy and immunotherapy of atopic eczema.

This article describes the core outcome set (COS) for atopic eczema trials. COS describe a minimum set of outcomes to be assessed in a defined situation. COS are required to overcome the current situation of different trials using different endpoints with unclear/insufficient measurement properties resulting in incomparable trials. The global multi-stakeholder Harmonising Outcomes Measures for Eczema initiative developed the Harmonising Outcomes Measures for Eczema roadmap as a generic framework for COS development. Following the establishment of a panel representing all stakeholders, a core set of outcome domains need to be selected based on systematic reviews and consensus methods. Outcome measurement instruments to assess these core domains need to be valid, reliable, and feasible. There is broad global consensus that clinical signs, quality of life, symptoms, and long-term control of flares form the COS for atopic eczema trials. The Eczema Area and Severity Index is recommended to assess clinical signs in atopic eczema trials. Systematic reviews to identify adequate outcome measurement instruments for the other core outcome domains are underway. Clinical signs should be assessed in all atopic eczema trials by at least the Eczema Area and Severity Index. Quality of life, symptoms, and flares should also be assessed in all atopic eczema trials by a valid, reliable, and feasible instrument.

Several genetic association studies have examined the relationships between single nucleotide polymorphisms (SNPs) in the IL13 gene and eczema, and have provided contradictory results. We investigated the relationship between the IL13 SNPs rs1800925 and rs20541 and the risk of eczema in Japanese young adult women. Included were 188 cases who met the criteria of the International Study of Asthma and Allergies in Childhood (ISAAC) for eczema. Control subjects were 1,082 women without eczema according to the ISAAC criteria, who had not been diagnosed with atopic eczema by a doctor and who had no current asthma as defined by the European Community Respiratory Health Survey criteria. Adjustment was made for age, region of residence, number of children, smoking, and education. The minor TT genotype of SNP rs1800925 was significantly associated with an increased risk of eczema in the co-dominant model: the adjusted odds ratio was 2.19 (95% confidence interval: 1.03-4.67). SNP rs20541 was not related to eczema. None of the haplotypes were significantly associated with eczema. Compared with women with the CC or CT genotype of SNP rs1800925 who had never smoked, those with the TT genotype who had ever smoked had a 2.85-fold increased risk of eczema, though the adjusted odds ratio was not statistically significant, and neither multiplicative nor additive interaction was statistically significant. Our findings suggest that the IL13 SNP rs1800925 is significantly associated with eczema in Japanese young adult women. We could not find evidence for an interaction between SNP rs1800925 and smoking with regard to eczema.

The present case-control study examined the relationship between IL5RA SNPs and eczema in young adult Japanese women. Cases and control subjects were selected from pregnant women who participated in the baseline survey of the Kyushu Okinawa Maternal and Child Health Study, which is an ongoing prebirth cohort study. Cases comprised 188 women with eczema in the previous 12 months as defined according to the criteria of the International Study of Asthma and Allergies in Childhood (ISAAC), regardless of the presence of a doctor's diagnosis of atopic eczema. Control subjects comprised 1130 women without eczema as defined according to the ISAAC criteria who also had not been diagnosed with atopic eczema by a doctor. Compared with the AA genotype of IL5RA SNP rs17881144, the AT genotype, but not the TT genotype, was significantly associated with a decreased risk of eczema. The ATTAGA haplotype and the GTAGCA haplotype of rs17882210, rs3804797, rs334809, rs9831572, rs6771148 and rs17881144 were significantly associated with an increased risk of eczema. In contrast, the GCTGCA haplotype was significantly related to a decreased risk of eczema. Multiplicative interactions between IL5RA SNPs rs334809 and rs17881144 and smoking with respect to eczema were marginally significant (P = 0.07 and 0.07, respectively). This is the first study to show significant associations between IL5RA SNP rs17881144, the ATTAGA haplotype, the GTAGCA haplotype, and the GCTGCA haplotype and eczema. Smoking may modify the relationships between SNPs rs334809 and rs17881144 and eczema. © 2014 John Wiley & Sons Ltd.

Loss-of-function mutations in the filaggrin (FLG) gene were identified as a major risk factor for atopic eczema. The aim of the study was to investigate the importance of 4 common FLG null mutations in the susceptibility to atopic eczema and other allergic phenotypes in Polish children population. The FLG mutations were determined in 158 children younger than 2 years of age. All subjects were selected using a detailed questionnaire and blood samples for total and specific IgE measurements were obtained. Cases of atopic eczema were diagnosed according to the criteria of Hanifin and Rajka and skin examination. All FLG mutations were genotyped by real-time PCR assays with a subsequent melting curve analysis using a SimpleProbe® probes. The combined genotype of all 4 mutations (carriage of ≥ 1 FLG mutation) was significantly associated with atopic eczema (p = 0.016). The odds ratio (OR) for individuals carrying 1 of these 4 null mutations was 5.52 (95% CI; 1.11 ÷ 37.12). The significant association between either the combined FLG genotype or 2282del14 deletion and eczema was seen only in the allergic group. The association with asthma was restricted to asthma occurring in the context of eczema (OR, 6.27; 95% CI, 0.89 ÷ 53.56; p = 0.042). Our study confirms the previous findings that FLG mutations are strongly associated with atopic eczema and confer a significant risk of allergic sensitization and asthma in the context of eczema. These results underline the role of the epidermal barrier and filaggrin insufficiency in the pathogenesis of atopic eczema and eczema-associated asthma.

Background: Recent cross-sectional studies suggest a link between butylbenzyl phthalate (BBzP) in house dust and childhood eczema. Objectives: We aimed to evaluate whether concentrations of monobenzyl phthalate (MBzP), the main BBzP metabolite in urine, during pregnancy are associated prospectively with eczema in young children, and whether this association varies by the child’s sensitization to indoor allergens or serological evidence of any allergies. Methods: MBzP was measured in spot urine samples during the third trimester of pregnancy from 407 African-American and Dominican women residing in New York City in 1999–2006. Repeated questionnaires asked mothers whether their doctor ever said their child had eczema. Child blood samples at 24, 36, and 60 months of age were analyzed for total, anti-cockroach, dust mite, and mouse IgE. Relative risks (RR) were estimated with multivariable modified Poisson regression. Analyses included a multinomial logistic regression model for early- and late-onset eczema versus no eczema through 60 months of age. Results: MBzP was detected in > 99% of samples (geometric mean = 13.6; interquartile range: 5.7–31.1 ng/mL). By 24 months, 30% of children developed eczema, with the proportion higher among African Americans (48%) than among Dominicans (21%) (p < 0.001). An interquartile range increase in log MBzP concentration was associated positively with early-onset eczema (RR = 1.52 for eczema by 24 months; 95% confidence interval: 1.21, 1.91, p = 0.0003, n = 113 reporting eczema/376 total sample), adjusting for urine specific gravity, sex, and race/ethnicity. MBzP was not associated with allergic sensitization, nor did seroatopy modify consistently the MBzP and eczema association. Conclusions: Prenatal exposure to BBzP may influence the risk of developing eczema in early childhood. PMID:22732598

The association between eczema and mental health problems in schoolchildren has been underexplored. We aimed to investigate this association with the validated questionnaires. Of 46,648 invited children, we analyzed 9954 (21.3%) in the 2nd to the 8th grades from the ToMMo Child Health Study conducted in 2014 and 2015, a cross-sectional survey in Miyagi Prefecture, Japan. We defined eczema status as "normal," "mild/moderate," or "severe," based on the presence of persistent flexural eczema and sleep disturbance, according to the International Study of Asthma and Allergies in Childhood (ISAAC) Eczema Symptom Questionnaire. Clinical ranges of Strengths and Difficulties Questionnaire (SDQ) total difficulties scores and four SDQ subcategories of emotional symptoms, conduct problems, hyperactivity/inattention, and peer problems were defined as scores ≥16, ≥5, ≥5, ≥7, and ≥5, respectively. The mean SDQ total difficulties score significantly increased as eczema status worsened (all P ≤ 0.004 for trend). The OR of scores in the clinical range for SDQ total difficulties were 1.51 (95% CI, 1.31-1.74) for mild/moderate eczema and 2.63 (95% CI, 1.91-3.63) for severe eczema (P < 0.001 for trend), adjusted for sex, school grade, current wheeze, and disaster-related factors, using normal eczema as a reference. The association between severity of eczema and four SDQ subcategories showed a similar trend (all P ≤ 0.017 for trend). We found a significant association between severity of eczema and mental health problems. The presence of eczema was associated with four SDQ subcategories.

To determine whether "herbal creams" reported as being effective for the treatment of childhood atopic eczema contained corticosteroids. Patients attending the paediatric dermatology clinic at Birmingham Children's Hospital, April 2001 to March 2002, and who reported using "herbal creams" with good effect for atopic eczema were asked to submit the cream for analysis. Hydrocortisone, clobetasone butyrate, betamethasone valerate, and clobetasol propionate were analysed by HPLC. Twenty four creams from 19 patients, median (interquartile range) age 3.82 (0.69-7.98) years were analysed. All five creams labelled Wau Wa and the two labelled Muijiza cream contained clobetasol propionate. Thirteen of 17 unnamed creams contained corticosteroids: clobetasol proprionate (n = 4), clobetasol proprionate + hydrocortisone (n = 1), betamethasone valerate (n = 2), clobetasone butyrate (n = 3), and hydrocortisone (n = 2); there was an unidentified peak in one. Further analysis suggested Wau Wa cream contained approximately 20% proprietary Dermovate Cream in a paraffin base. No parents were aware that the creams contained steroid. The majority of herbal creams analysed illegally contained potent or very potent topical steroids. There is an urgent need for tighter regulation of herbal creams and for increased public education about the potential dangers of alternative therapies.

Exposure to low levels of vitamin D in fetal life might affect the developing immune system, and subsequently the risk of childhood eczema. We examined whether 25-hydroxyvitamin D levels in mid-gestation and at birth were associated with the risk of eczema until the age of 4 years. In a population-based prospective cohort study of 3019 mothers and their children, maternal blood samples in mid-gestation and umbilical cord blood samples at birth were used to determine 25-hydroxyvitamin D levels (severely deficient <25.0 nmol/l, deficient 25.0-49.9 nmol/l, sufficient 50.0-74.9 nmol/l, optimal ≥75.0 nmol/l). Eczema was prospectively assessed by annual questionnaires until the age of 4 years. Eczema patterns included never, early (age ≤1 year only), late (age >1 year only), and persistent eczema (age ≤ and >1 year). Data were assessed using the generalized estimating equations and multinomial regression models. Compared with the optimal 25-hydroxyvitamin D group, sufficient, deficient, and severely deficient groups of 25-hydroxyvitamin D level in mid-gestation were not associated with the risk of overall eczema (odds ratios [95% confidence interval]: 1.09 [0.82, 1.43], 1.04 [0.87, 1.25], and 0.94 [0.81, 1.10], p-values for trend >0.05), nor with eczema per year or eczema patterns in children up to the age of 4 years. Similarly, we observed no associations of 25-hydroxyvitamin D groups at birth with any eczema outcome. Our results suggest that levels of 25-hydroxyvitamin D in mid-gestation and at birth are not associated with the risk of overall eczema, eczema per year, or eczema patterns among children until the age of 4 years. © 2015 John Wiley & Sons A/S.

What's new in atopic eczema? An analysis of systematic reviews published in 2007 and 2008. Part 2. Disease prevention and treatment.

Williams, H C; Grindlay, D J C

2010-04-01

This review summarizes clinically important findings from systematic reviews indexed in bibliographical databases between August 2007 and August 2008 that dealt with disease prevention (six reviews) and treatment of atopic eczema (seven reviews). Regarding disease prevention, two independent systematic reviews found some clinical trial evidence that ingestion of probiotics by mothers during pregnancy might reduce the incidence of subsequent eczema. Another review failed to find any clear benefit of prebiotics in eczema prevention. Although furry pets are often cited as causing allergic disease, a systematic review of observational studies found no evidence that exposure to cats or dogs at birth increases eczema risk. One very large review of studies of breastfeeding found some evidence of a protective effect on eczema risk, although all the studies were limited by their observational nature. A German group has attempted an overview of eczema prevention studies with a view to informing national guidelines. In terms of eczema treatment, two systematic reviews have confirmed the efficacy of topical tacrolimus ointment. Another review of 31 trials confirms the efficacy of topical pimecrolimus, although many of those trials were vehicle controlled, which limits their clinical utility. A review of 23 studies of desensitization therapy for allergic diseases found some evidence of benefit for eczema, which needs to be explored further. Despite the popularity of antistaphylococcal therapies for eczema, a Cochrane Review of 21 trials failed to show any clear benefit for any of the therapies for infected or clinically noninfected eczema. Another Cochrane Review dealt with dietary exclusions for people with eczema and found little evidence to support any dietary exclusion, apart from avoidance of eggs in infants with suspected egg allergy supported by evidence of sensitization. A review of 13 studies of probiotics for treating established eczema did not show convincing evidence of a clinically worthwhile benefit, an observation that has been substantiated in a subsequent Cochrane Review.

A recent Danish study showed a significant increase in the prevalence of chromate contact allergy after the mid-1990s, probably as a result of exposure to leather products. To reproduce the results by analysing data from the period 1992-2009 at Odense University Hospital, Denmark. The temporal development in the occurrence of chromate contact allergy and assumed causative exposures were investigated. A retrospective analysis of patch test data was performed (n = 8483), and medical charts from patients with chromate allergy (n = 231) were reviewed. Comparisons were made using the χ(2) -test. A test of the reproducibility of the TRUE Test® was also performed. Logistic regression analyses were used to test for associations. No significant changes in the prevalence or exposure sources of chromate allergy during 1992-2009 were identified. Leather shoes (24.4%) were the most frequent exposure sources in chromate allergy, and were mainly registered in women, although the difference between men and women was not significant (P = 0.07). Cement and leather glove exposure occurred significantly more often in men than in women (P = 0.002). Foot dermatitis (40.3%) was the most frequent anatomical location, apart from hand eczema (60.6%). The reproducibility of the TRUE Test® was 93.3%. Apart from hand eczema, the most frequent clinical picture of chromate allergy was foot dermatitis caused by leather shoe exposure. A tendency for an increasing prevalence of chromate contact allergy from 1997 was shown, but no significant change was detectable. © 2010 John Wiley & Sons A/S.

We examined the association between thymic stromal lymphopoietin (TSLP) single nucleotide polymorphisms (SNPs) and eczema in young adult Japanese women. Cases were 188 women who met the criteria of the International Study of Asthma and Allergies in Childhood (ISAAC) for eczema. Controls were 565 women without eczema according to the ISAAC criteria, who had not been diagnosed with asthma, atopic eczema, and/or allergic rhinitis by a doctor and who had no asthma as defined by the European Community Respiratory Health Survey criteria and no rhinoconjunctivitis according to the ISAAC criteria. Compared with women with the TT genotype of SNP rs1837253, those with the TC or CC genotype had a significantly increased risk of eczema after adjustment for age and smoking, although this association was not significant in crude analysis. There were no relationships between SNP rs3806933 or rs2289276 and eczema. The TC and CC genotypes combined of SNP rs1837253 may be significantly positively associated with eczema.

Asthma is often difficult to control and it is likely that not all patients are optimally treated. This study aimed to explore asthma control in adults receiving fixed dose combination (FDC) therapy. Control of asthma was assessed using the mannitol challenge test as a monitoring tool to see if this would give additional information compared to the asthma control test (ACT). The study was an open-label, prospective study on 98 adults prescribed with FDC therapies for at least three months. 74 patients considered that their asthma was well controlled. However, 60 patients had a positive mannitol challenge test (PD15 < 635 mg), and when those with a positive response to the short-acting β2-agonist (≥15%) after the mannitol challenge test were included, this increased to 64 patients (65%). Exploratory analysis determined that the spirometry parameters; FEV1/FVC and FEV1% of predicted, were statistically significant predictors of a positive mannitol challenge test. Co-morbid conditions such as concomitant upper airway involvement or eczema did not predict mannitol reactivity. Although most patients rated their asthma as well controlled, many provided a positive mannitol challenge test, suggesting the presence of underlying inflammation, despite treatment with fixed dose combination therapy.

Numerous risk factors have been suggested for hand eczema. This systematic review evaluates the association between tobacco smoking and hand eczema. To review the literature systematically on the association between smoking and hand eczema. The PubMed and EMBASE databases were searched up to 27 January 2015 for articles on the association between tobacco smoking and hand eczema, including human studies in English and German only. Experimental studies, studies on tobacco allergy, case reports, reviews and studies on second-hand smoking were excluded. Twenty articles were included. Among studies in occupational settings, three of seven found a statistically significant positive association between tobacco smoking and hand eczema prevalence rate, as did four of eight population-based studies. The association was stronger for studies in occupational settings than for population-based studies. No studies reported tobacco to be a clear protective factor for hand eczema. Two of five studies regarding severity found a positive association between smoking and hand eczema severity. Overall, the data indicate that smoking may cause an increased frequency of hand eczema, particularly in high-risk occupations. However, data from studies controlling for other risk factors are conflicting, and few prospective studies are available. Studies controlling for other risk factors are needed, and information regarding the diagnosis of subclasses of hand eczema, as well as severity, may be important. © 2015 John Wiley & Sons A/S.

Dietary factors may be important in the development of atopic eczema. It remains controversial whether n-3 polyunsaturated fatty acid intake is preventive against allergic disorders and whether n-6 polyunsaturated fatty acid intake increases the risk of allergic disorders. The current cross-sectional study examined the association between intake of fatty acids and foods high in fatty acids and the prevalence of atopic eczema. Study subjects were 1002 pregnant Japanese females. Current atopic eczema and atopic eczema after age 18 were defined as present if subjects had been treated with medications at some time in the previous 12 months and after reaching the age of 18, respectively. Information on dietary factors was collected using a validated self-administered diet history questionnaire. Docosahexaenoic acid intake was statistically significantly related to a decreased prevalence of atopic eczema after age 18 and current atopic eczema. Inverse dose-response relationships with regard to consumption of n-3 polyunsaturated fatty acids, eicosapentaenoic acid, and fish and the ratio of n-3 to n-6 polyunsaturated fatty acids with atopic eczema were not observed although these dietary variables in the second tertile were inversely significantly associated with atopic eczema after age 18. Intake of total fat, saturated fatty acids, monounsaturated fatty acids, n-6 polyunsaturated fatty acids, cholesterol, meat, eggs, or dairy products was not related to either of the outcomes for atopic eczema. Docosahexaenoic acid intake may be associated with a reduced prevalence of atopic eczema in pregnant Japanese females.

Chemical exposures at work and at home may cause hand eczema. However, this has been scarcely described for Norway. To investigate the prevalence of, and occupational risk factors for, hand eczema in Norway. Among 50 805 respondents (aged ≥20 years) to the third Nord-Trøndelag Health Study (HUNT3), 5757 persons reported ever having hand eczema, and 4206 answered a hand eczema questionnaire. The lifetime prevalences of hand eczema were 8.4% in men and 13.8% in women (p < 0.001), with onset at age ≤10 years in 24% (men) and 20% (women), and onset at age ≥30 years in 37% (men) and 25% (women) (p < 0.001). Work-related hand eczema affected 4.8% of the population, and was most frequently associated with health/social work (29%) and occupational cleaning (20%) in women, and with farming (26%) and industrial occupations (27%) in men. Cleaning detergents (75%) and other chemicals (36%) were the most common exacerbating factors. The prevalence of hand eczema was 11.3%, and that of work-related hand eczema was 4.8%. Hand eczema was more common in women than in men, but with a later onset in men. Cleaning detergents were the most common aggravating factors. A large proportion of the Nord-Trøndelag population is employed in farming, providing the possibility to identify farming as an important risk factor for hand eczema. © 2017 John Wiley & Sons A/S.

There is a well-known association between atopic dermatitis (AD) and hand eczema but less is known about how age at onset, persistence and severity of AD influence the risk of developing hand eczema. To examine the role of AD in the occurrence of hand eczema in adolescence. In addition, associations between asthma and rhinoconjunctivitis, sensitization to common airborne and food allergens, and hand eczema were studied. From the population-based birth cohort BAMSE, 2927 adolescents who had been followed up repeatedly concerning allergy-related disease were included. Questionnaires identified adolescents with hand eczema at 16 years, and their blood was analysed for specific IgE. A total of 152 (5·2%) adolescents had hand eczema at the age of 16 years. Many of these adolescents had a history of AD (n = 111; 73·0%) and asthma and/or rhinitis (n = 83; 54·6%), respectively. Children with AD (aged 0-16 years) had more than threefold increased odds ratios (OR) for having hand eczema; those with persistent or severe AD had a crude OR of 6·1 [95% confidence interval (CI) 4·0-9·1] and 5·3 (95% CI 2·9-9·6), respectively. We confirm a strong association between AD during childhood and hand eczema in adolescence. Children with persistent or more severe AD are at greater risk of developing hand eczema. Asthma and/or rhinoconjunctivitis, positive specific IgE or age at onset of AD are not associated with hand eczema in adolescence. © 2015 British Association of Dermatologists.

Although psychological factors are widely considered to be important in atopic eczema, there have been few controlled studies to assess the extent of disturbance in affected children and the problems experienced by their parents. This study was designed to find out the degree of psychological difficulty experienced by children with atopic eczema, whether their mothers show higher levels of mental distress than a comparison group, and whether the families of children with atopic eczema have less social support than the comparison group. We investigated 30 school-aged children with atopic eczema for psychological problems using the Rutter parent scale and compared them with 30 children with relatively minor skin lesions such as viral warts. Mental distress in mothers was assessed using the General Health Questionnaire. The Family Support Scale was used to get a measure of the social support experienced by the families. We found twice the rate of psychological disturbance in children in the eczema group compared with the control group. This difference was statistically significant for children with moderately severe eczema and severe eczema, but not for children with very mild eczema. Levels of mental distress were no greater in mothers of children with eczema than in parents of the control group and there was no difference in the degree of social support experienced by their families. These findings indicate that school-aged children with moderate and severe atopic eczema are at high risk of developing psychological difficulties, which may have implications for their academic and social development.

Allergic airborne contact dermatitis from essential oils used in aromatherapy.

PubMed

Schaller, M; Korting, H C

1995-03-01

Contact allergy to various essential oils used in aromatherapy was demonstrated on patch testing in a 53-year-old patient suffering from relapsing eczema resistant to therapy on various uncovered parts of the skin, in particular the scalp, neck and hands. Sensitization was due to previous exposure to lavender, jasmine and rosewood. Laurel, eucalyptus and pomerance also produced positive tests, although there was no hint of previous exposure. A diagnosis of allergic airborne contact dermatitis was thus established. On topical and systemic glucocorticoid treatment (peroral methylprednisolone at an initial dose of 60 mg/day) the skin lesions eventually resolved. Due to persistence of the volatile essential oils in the patient's home after a year-long use of aroma lamps, complete renewal of the interior of the patient's flat was considered essential. Due to changing self-medication habits, with increasing orientation to 'natural' modes of treatment, increasing numbers of such sensitizations might be on the horizon.

Several fruits have been reported to crossreact with latex antigen in latex allergy patients but little is known regarding tropical fruits in particular. Here we report the case of a 34-year old nurse who developed anaphylaxis following the ingestion of dried jackfruit (Artocarpus heterophyllus). The patient had a history of chronic eczema on both hands resulting from a regular wear of latex gloves. She and her family also had a history of atopy (allergic rhinitis and/or atopic dermatitis). The results of skin prick tests were positive for jackfruit, latex glove, kiwi and papaya, but the test was negative for banana. While we are reporting the first case of jackfruit anaphylaxis, further research needs to be conducted to identify the mechanisms underlying it. In particular, in-vitro studies need to be designed to understand if the anaphylaxis we describe is due to a cross reactivity between latex and jackfruit or a coincidence of allergy to these 2 antigens.

Epidemiological evidence suggests that routine vaccinations can have nontargeted effects on susceptibility to infections and allergic disease. Such effects may depend on age at vaccination, and a delay in pertussis vaccination has been linked to reduced risk of allergic disease. We aimed to test the hypothesis that delay in vaccines containing diphtheria-tetanus-acellular pertussis (DTaP) is associated with reduced risk of food allergy and other allergic diseases. HealthNuts is a population-based cohort in Melbourne, Australia. Twelve-month-old infants were skin prick-tested to common food allergens, and sensitized infants were offered oral food challenges to determine food allergy status. In this data linkage study, vaccination data for children in the HealthNuts cohort were obtained from the Australian Childhood Immunisation Register. Associations were examined between age at the first dose of DTaP and allergic disease. Of 4433 children, 109 (2.5%) received the first dose of DTaP one month late (delayed DTaP). Overall, delayed DTaP was not associated with primary outcomes of food allergy (adjusted odds ratio (aOR) 0.77; 95% CI: 0.36-1.62, P = 0.49) or atopic sensitization (aOR: 0.66; 95% CI: 0.35-1.24, P = 0.19). Amongst secondary outcomes, delayed DTaP was associated with reduced eczema (aOR: 0.57; 95% CI: 0.34-0.97, P = 0.04) and reduced use of eczema medication (aOR: 0.45; 95% CI: 0.24-0.83, P = 0.01). There was no overall association between delayed DTaP and food allergy; however, children with delayed DTaP had less eczema and less use of eczema medication. Timing of routine infant immunizations may affect susceptibility to allergic disease. © 2015 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Epidemiological studies to determine the burden of skin diseases are important for proper health care planning. The purpose of this study was to find the pattern of skin diseases in our patients attending university-affiliated dermatologic clinics in the Qassim region. We conducted a prospective study of all Saudi patients attending the Qassim University Medical College-affiliated dermatology clinics of the Ministry of Health for a period of 12 months from 1 March 2008 to 28 February 2009. The study included 3051 patients comprising 1786 (58.5%) males and 1265 (41.5%) females. Males outnumbered females (P<.05) (male-to-female ratio, 1.4:1). The mean age (standard error of the mean) of the patients was 25.3 (0.27) years. About 71% of the patients were between 5 and 34 years of age. The top five skin diseases were eczema/ dermatitis (19.5%), viral infections (16.6%), pilosebaceous disorders (14.4%), pigmentary lesions (11.2%) and hair disorders (7.6%). The major disorder in males was viral skin infections (20.0%), while eczema/dermatitis (20.7%) constituted the most prevalent skin disease in females. Seasonal variations were recorded in cases of pigmentary lesions, papulosquamous disorders and protozoal infections. Infectious skin diseases, eczema/dermatitis, pilosebaceous disorders, pigmentary lesions and hair disorders ranked as the top five skin diseases. Appropriate training programs for diagnosing and managing common skin diseases should be initiated for primary health care physicians and other general practitioners so as to decrease referrals to dermatology clinics.

Experimental Eczema. 16. Diminution of the Eczematous Reaction in Preirradiated Guinea Pigs (in French)

Irradiation of small areas of guinea pig skin with 1600 r produced persistent alopecia and acanthosis, without any other subsequent histologic or macroscopic changes in skin. Forty days after such local irradiation of skin, the animals were sensitized to chlorodinitrobenzene and skin reactions were tested with the same compound 7 days later on both the irradiated and control areas. In contrast to the intense eczema developing in control skin, irradiated skin showed a complete lack of reactivity to the allergen. lt was shown that the absence of reactivity in irradiated skin was not the result of the existing acanthosis, sincemore » acanthosis induced by applications of erucic acid did not block the eczematous response to the allergen. Nor was the lack of reactivity due to the absence of hair, since radiationinduced inhibition of eczema could be demonstrated in skin normally lacking hair (nipples).« less

To determine the feasibility of a randomised controlled trial of 'leave on' emollients for children with eczema. Single-centre, pragmatic, 4-arm, observer-blinded, parallel, randomised feasibility trial. General practices in the UK. Children with eczema aged 1 month to <5 years. Primary outcome-proportion of parents who reported use of the allocated study emollient every day for the duration of follow-up (12 weeks). Other feasibility outcomes-participant recruitment and retention, data collection and completeness and blinding of observers to allocation. Aveeno lotion, Diprobase cream, Doublebase gel, Hydromol ointment. 197 children were recruited-107 by self-referral (mainly via practice mail-outs) and 90 by inconsultation (clinician consenting and randomising) pathways. Participants recruited inconsultation were younger, had more severe Patient-Oriented Eczema Measure scores and were more likely to withdraw than self-referrals. Parents of 20 (10%) of all the randomised participants reported using the allocated emollient daily for 84 days. The use of other non-study emollients was common. Completeness of data collected by parent-held daily diaries and at monthly study visits was good. Daily diaries were liked (81%) but mainly completed on paper rather than via electronic ('app') form. Major costs drivers were general practitioner consultations and eczema-related prescriptions. Observer unblinding was infrequent, and occurred at the baseline or first follow-up visit through accidental disclosure. It is feasible in a primary care setting to recruit and randomise young children with eczema to emollients, follow them up and collect relevant trial data, while keeping observers blinded to their allocation. However, reported use of emollients (study and others) has design implications for future trials. ISRCTN21828118/EudraCT2013-003001-26. Published by the BMJ Publishing Group Limited.

A 24-year-old female working in the Department of Pathology of a University Hospital developed an acute peri-ocular eczema clearly being related to her daily work at the microscope. Patch testing revealed delayed type hypersensitivity against the black rubber mix, N-isopropyl-N'-phenyl paraphenylenediamine, N-cyclohexyl-N'-phenyl paraphenylenediamine and the rubber ring situated on the ocular of the respective microscope. This is the first report, to our knowledge, on peri-orbital allergic contact eczema because of sensitization with rubber components of a microscope.

We review clinical information on 141 individuals with Dubowitz syndrome, 105 reported since 1965, and 36 previously unreported. We define the Dubowitz syndrome phenotype on the basis of clinical descriptions. The facial appearance is characteristic and present in most patients with Dubowitz syndrome. The phenotypic spectrum is quite variable and ranges from normal growth and head circumference with mild psychomotor retardation and lack of eczema to a condition of severe growth retardation, mental retardation, microcephaly, and eczema. Overall, the condition may involve the cutaneous, ocular, dental, digestive, musculoskeletal, urogenital, cardiovascular, neurological, hematological, and immune systems. Characteristic behavior patterns which have not been cited previously are present in our cases; most patients are hyperactive, shy, hate crowds, and like music, rhythm, and vibrations from music speakers, tape recorders, or transmitted through floors. Dubowitz syndrome is an autosomal recessive disorder with possibly increased frequency of parental consanguinity. Heterogeneity cannot be excluded at this time.

Paediatric eczema and psychosocial morbidity: how does eczema interact with parents' illness beliefs?

PubMed

Walker, C; Papadopoulos, L; Hussein, M

2007-01-01

Thus far there has been relatively little work on children's illness representations regarding eczema and how these relate to parental conceptualizations of their child's psychosocial health. This is important because the challenge of raising a child with a serious illness can affect many facets of a parent's everyday life and the behaviour of parents can be closely related to the health of the child. Two hundred and thirty-two children with eczema, asthma, eczema and asthma, and healthy controls between 7 and 12 years of age and their parents were recruited. Children were administered the Children's Illness Perception Questionnaire. Questionnaires completed by the parents were The Personality Inventory for Children and The Parental Stress Inventory. Parents of children with eczema did not judge their children to have poorer psychosocial health than controls, but parents of children with eczema could not be distinguished between in terms of whether their child was significantly affected by their eczema or not. This work could have important implications for the quality of life of the child and for the parent-child relationship and these implications are considered.

Eczema is frequently the first manifestation of an atopic diathesis and alteration in the diversity of gut microbiota has been reported in infants with eczema. To identify specific bacterial communities associated with eczema, we conducted a case-control study of 50 infants with eczema (cases) and 51 healthy infants (controls). We performed high-throughput sequencing for V3-V4 hypervariable regions of the 16S rRNA genes from the gut fecal material. A total of 12,386 OTUs (operational taxonomic units) at a 97% similarity level were obtained from the two groups, and we observed a difference in taxa abundance, but not the taxonomic composition, of gut microbiota between the two groups. We identified four genera enriched in healthy infants: Bifidobacterium, Megasphaera, Haemophilus and Streptococcus; and five genera enriched in infants with eczema: Escherichia/Shigella, Veillonella, Faecalibacterium, Lachnospiraceae incertae sedis and Clostridium XlVa. Several species, such as Faecalibacterium prausnitzii and Ruminococcus gnavus, that are known to be associated with atopy or inflammation, were found to be significantly enriched in infants with eczema. Higher abundance of Akkermansia muciniphila in eczematous infants might reduce the integrity of intestinal barrier function and therefore increase the risk of developing eczema. On the other hand, Bacteroides fragilis and Streptococcus salivarius, which are known for their anti-inflammatory properties, were less abundant in infants with eczema. The observed differences in genera and species between cases and controls in this study may provide insight into the link between the microbiome and eczema risk.

The evidence for a preventive effect of breast-feeding on the development of eczema in childhood remains controversial. To investigate the effect of breast-feeding in various phenotypes of eczema to 4 years. A birth cohort of 4089 children made up the study base. Data on breast-feeding, allergic symptoms, and potential confounders were obtained from questionnaires when the children were 2 months and 1, 2, and 4 years old. At 4 years, blood specific IgE was analyzed. Children with symptoms of eczema and asthma during the period of breast-feeding were excluded in most analyses on risk assessment of eczema and asthma, respectively, to avoid disease-related modification of exposure. Exclusive breast-feeding for >or=4 months reduced the risk for eczema at the age of 4 years (odds ratio [OR], 0.78; 95% CI, 0.63--0.96) irrespective of combination with asthma, sensitization to common allergens, or parental allergic disease. This decreased risk was most evident for children with onset of eczema during the first 2 years persisting to 4 years (OR, 0.59; 95% CI, 0.45--0.77). Among children with early-onset eczema, irrespective of persistency, followed by late onset of asthma or early-onset asthma irrespective of persistency, followed by late-onset eczema to 4 years, a protective effect of breast-feeding was also seen (OR, 0.48; 95% CI, 0.30--0.76). Breast-feeding 4 months or more reduces the risk for eczema and onset of the allergy march to age 4.

Atopic eczema is most commonly diagnosed in children under the age of 5 yr. Environmental factors during pregnancy or in early life may confer risk for childhood atopic eczema. The present prospective study examined the relationship of the perinatal home environment and the risk of suspected atopic eczema among Japanese infants under the age of 1. Study subjects were 865 parent-child pairs. The term 'suspected atopic eczema' was used to define an outcome based on our questionnaire at 2-9 months postpartum. Adjustment was made for maternal age, gestation, family income, maternal and paternal education, maternal and paternal history of asthma, atopic eczema, and allergic rhinitis, time of delivery before the second survey, baby's older siblings, baby's sex, and baby's birth weight. A high mite allergen level from maternal bedclothes and mold in the kitchen during pregnancy were significantly associated with an increased risk of suspected atopic eczema. Frequent vacuuming practices during pregnancy and giving the infant a bath or shower at least once a day were significantly inversely related to the risk of suspected atopic eczema. Maternal smoking, maternal use of a synthetic duvet and pillow, carpet use in the living room and maternal bedroom, indoor domestic pets, no ducted heating appliance, and gas use for cooking during pregnancy and household smoking in the same room as the infant, infant's synthetic duvet, carpet use in the infant's room, or vacuuming the infant's room were not related to the risk of suspected atopic eczema. High house dust mite allergen levels and mold in the kitchen during pregnancy may increase the risk of infantile atopic eczema, whereas frequent vacuuming practices during pregnancy and giving the infant a bath or shower at least once a day may protect against infantile atopic eczema.

Several association studies have investigated the relationships between single nucleotide polymorphisms (SNPs) in the IL13 gene and eczema, with inconsistent results. We conducted a case-control study of the relationship between the polymorphisms of rs1800925 and rs20541 and the risk of eczema in Japanese children aged 3 years. Included were the 209 cases identified based on criteria of the International Study of Asthma and Allergies in Childhood (ISAAC). Controls were 451 children without eczema based on ISAAC questions who had not been diagnosed by a physician as having asthma or atopic eczema. The minor TT genotype of the rs1800925 SNP and the minor AA genotype of the rs20541 SNP were significantly related to an increased risk of eczema: adjusted odds ratio for the TT genotype was 2.78 (95% confidence interval 1.22-6.30) and that for the AA genotype was 2.38 (95% confidence interval 1.35-4.18). Haplotype analyses showed a protective association between the CG haplotype and eczema, whereas the TA haplotype was positively related to the risk of eczema. Perinatal smoking exposure did not interact with genotypes of the IL13 gene in the etiology of eczema. The significant association of the rs20541 SNP with eczema essentially disappeared after additional adjustment for the rs1800925 SNP, whereas a relationship with the rs1800925 SNP remained significant. A common genetic variation in the IL13 gene at the levels of both single SNPs and haplotypes was associated with eczema. However, the significant association with the rs20541 SNP might be ascribed to the rs1800925 SNP. Copyright © 2010 S. Karger AG, Basel.

To determine if eczema is associated with an increased risk of a speech disorder. We analyzed data on 354,416 children and adolescents from 19 US population-based cohorts: the 2003-2004 and 2007-2008 National Survey of Children's Health and 1997-2013 National Health Interview Survey, each prospective, questionnaire-based cohorts. In multivariate survey logistic regression models adjusting for sociodemographics and comorbid allergic disease, eczema was significantly associated with higher odds of speech disorder in 12 of 19 cohorts (P < .05). The pooled prevalence of speech disorder in children with eczema was 4.7% (95% CI 4.5%-5.0%) compared with 2.2% (95% CI 2.2%-2.3%) in children without eczema. In pooled multivariate analysis, eczema was associated with increased odds of speech disorder (aOR [95% CI] 1.81 [1.57-2.05], P < .001). In a single study assessing eczema severity, mild (1.36 [1.02-1.81], P = .03) and severe eczema (3.56 [1.70-7.48], P < .001) were associated with higher odds of speech disorder. History of eczema was associated with moderate (2.35 [1.34-4.10], P = .003) and severe (2.28 [1.11-4.72], P = .03) speech disorder. Finally, significant interactions were found, such that children with both eczema and attention deficit disorder with or without hyperactivity or sleep disturbance had vastly increased risk of speech disorders than either by itself. Pediatric eczema may be associated with increased risk of speech disorder. Further, prospective studies are needed to characterize the exact nature of this association. Copyright © 2016 Elsevier Inc.

Atopic dermatitis (eczema) in childhood is socially patterned, with higher incidence in more advantaged populations. However, it is unclear what factors explain the social differences. To identify early-life risk factors for eczema, and to explore how early-life risk factors explain any differences in eczema. We estimated odds ratios (ORs) for ever having had eczema by age 5 years in 14 499 children from the U.K. Millennium Cohort Study (MCS), with a focus on maternal, antenatal and early-life risk factors and socioeconomic circumstances (SECs). Risk factors were explored to assess whether they attenuated associations between SECs and eczema. Overall 35·1% of children had ever had eczema by age 5 years. Children of mothers with degree-level qualifications vs. no educational qualifications were more likely to have eczema (OR 1·52, 95% confidence interval 1·31-1·76), and there was a gradient across the socioeconomic spectrum. Maternal atopy, breastfeeding (1-6 weeks and ≥ 6 months), introduction of solids under 4 months or cow's milk under 9 months, antibiotic exposure in the first year of life and grime exposure were associated with an increased odds of having eczema. Female sex, Pakistani and Bangladeshi ethnicity, smoking during pregnancy, exposure to environmental tobacco smoke and having more siblings were associated with reduced odds for eczema. Controlling for maternal, antenatal and early-life characteristics (particularly maternal smoking during pregnancy, breastfeeding and number of siblings) reduced the OR for eczema to 1·26 (95% confidence interval 1·03-1·50) in the group with the highest educational qualifications compared with the least. In a representative U.K. child cohort, eczema was more common in more advantaged children. This was explained partially by early-life factors including not smoking during pregnancy, breastfeeding and having fewer siblings. © 2015 The Authors.

Developmental Profiles of Eczema, Wheeze, and Rhinitis: Two Population-Based Birth Cohort Studies

PubMed Central

2014-01-01

Background The term “atopic march” has been used to imply a natural progression of a cascade of symptoms from eczema to asthma and rhinitis through childhood. We hypothesize that this expression does not adequately describe the natural history of eczema, wheeze, and rhinitis during childhood. We propose that this paradigm arose from cross-sectional analyses of longitudinal studies, and may reflect a population pattern that may not predominate at the individual level. Methods and Findings Data from 9,801 children in two population-based birth cohorts were used to determine individual profiles of eczema, wheeze, and rhinitis and whether the manifestations of these symptoms followed an atopic march pattern. Children were assessed at ages 1, 3, 5, 8, and 11 y. We used Bayesian machine learning methods to identify distinct latent classes based on individual profiles of eczema, wheeze, and rhinitis. This approach allowed us to identify groups of children with similar patterns of eczema, wheeze, and rhinitis over time. Using a latent disease profile model, the data were best described by eight latent classes: no disease (51.3%), atopic march (3.1%), persistent eczema and wheeze (2.7%), persistent eczema with later-onset rhinitis (4.7%), persistent wheeze with later-onset rhinitis (5.7%), transient wheeze (7.7%), eczema only (15.3%), and rhinitis only (9.6%). When latent variable modelling was carried out separately for the two cohorts, similar results were obtained. Highly concordant patterns of sensitisation were associated with different profiles of eczema, rhinitis, and wheeze. The main limitation of this study was the difference in wording of the questions used to ascertain the presence of eczema, wheeze, and rhinitis in the two cohorts. Conclusions The developmental profiles of eczema, wheeze, and rhinitis are heterogeneous; only a small proportion of children (∼7% of those with symptoms) follow trajectory profiles resembling the atopic march.

Intravenous immunoglobulin (IVIg) treatment is highly effective for autoimmune diseases including myasthenia gravis. Recovery is observed at approximately. 75% of myasthenia gravis patients through IVIg treatment. As a result of many clinical studies, the recommended dose is determined as 0.4 g/kg for 5 days (maximum total dose at 2 g/kg body weight). If an additional immunomodulatory treatment is not administered, IVIg maintenance treatment is needed mostly. However, some side effects may inhibit long-term treatment. For this reason, it is important to know the effect profile well and when the treatment should be discontinued. A female myasthenia gravis patient case is presented here, where dyshidrotic eczema has occurred after the second dose of  intravenous Ig medication and whose treatment is despite further IVIg therapy.

Stress is known to activate or exacerbate dermatoses, but the relationships between chronic stress, job-related stress and sickness absence among occupational hand eczema (OHE) patients are inadequately understood. To see whether chronic stress or burnout symptoms were associated with cumulative sickness absence in patients with OHE and to determine which factors predicted sickness absence in a model including measures of job-related and chronic stress. We investigated correlations of these factors in employed adult inpatients with a history of sickness absence due to OHE in a retrospective cross-sectional explorative study, which assessed chronic stress (Trier Inventory for the Assessment of Chronic Stress), burnout (Shirom Melamed Burnout Measure), clinical symptom severity (Osnabrück Hand Eczema Severity Index), perceived symptom severity, demographic characteristics and cumulative days of sickness absence. The study group consisted of 122 patients. OHE symptoms were not more severe among patients experiencing greater stress and burnout. Women reported higher levels of chronic stress on some measures. Cumulative days of sickness absence correlated with individual dimensions of job-related stress and, in multiple regression analysis, with an overall measure of chronic stress. Chronic stress is an additional factor predicting cumulative sickness absence among severely affected OHE patients. Other relevant factors for this study sample included the 'cognitive weariness' subscale of the Shirom Melamed Burnout Measure and the physical component summary score of the SF-36, a measure of health-related life quality. Prevention and rehabilitation should take job stress into consideration in multidisciplinary treatment strategies for severely affected OHE patients. © The Author 2014.

Washing the hands using cleansers with antiseptic materials is the most popular method for hand hygiene and helps maintain health by preventing food poisoning and bacterial infections. However, repeated hand washing tends to induce eczema of the hand, such as dryness, cracking and erythema. Moreover, eczema on the hand leads to increased levels in Staphylococcus aureus (S. aureus) on the skin surface in contrast to expectations. Thus, mild hand cleansers which induce less eczema even with repeated washings are desired. Here, we evaluated the efficacy of a hand cleanser formulated with alkyl ether sulphate (AES), alkyl ether carboxylic acid (AEC) and alkyl glucoside (AG) that contains isopropyl methylphenol (IPMP) on skin symptoms and S. aureus levels. Eczema of the hand and the presence of S. aureus on the skin surface were analysed prior to and following 4 weeks of usage of the hand cleanser. A soap-based hand cleanser with IPMP was used as a reference cleanser. Eczema and cutaneous conditions were evaluated by visual grading, transepidermal water loss (TEWL), stratum corneum moisture-retention ability (MRA) and skin surface pH. The repeated use of the soap-based hand cleanser significantly worsened the hand dryness, scaling and cracks on the tips of the fingers and significantly increased the TEWL and decreased the MRA. In contrast, usage of the test cleanser only induced a significant increase in skin dryness but did not induce skin scaling or cracking and did not increase TEWL or decrease the MRA. Corresponding to these changes in skin symptoms, the presence of S. aureus increased the following use of the reference cleanser but not the test cleanser. There was no significant difference in skin surface pH between the two cleansers. Moreover, the increase in S. aureus was significantly correlated to the worsening of skin dryness and scaling. These results suggest that not only antimicrobial activity but also the mildness, which minimizes cutaneous effects, are important for hand cleansers to prevent the growth of S. aureus. The cleanser formulated with AES, AEC and AG containing IPMP is mild and is effective to promote hand hygiene. © 2016 Society of Cosmetic Scientists and the Société Française de Cosmétologie.

Staphylococcus aureus skin colonization is universal in atopic dermatitis and common in cancer patients treated with epidermal growth factor receptor inhibitors. However, the causal relationship of dysbiosis and eczema has yet to be clarified. Herein, we demonstrate that Adam17(fl/fl)Sox9-(Cre) mice, generated to model ADAM17-deficiency in human, developed eczematous dermatitis with naturally occurring dysbiosis, similar to that observed in atopic dermatitis. Corynebacterium mastitidis, S. aureus, and Corynebacterium bovis sequentially emerged during the onset of eczematous dermatitis, and antibiotics specific for these bacterial species almost completely reversed dysbiosis and eliminated skin inflammation. Whereas S. aureus prominently drove eczema formation, C. bovis induced robust T helper 2 cell responses. Langerhans cells were required for eliciting immune responses against S. aureus inoculation. These results characterize differential contributions of dysbiotic flora during eczema formation, and highlight the microbiota-host immunity axis as a possible target for future therapeutics in eczematous dermatitis.

[Percutaneous sensitization to almond oil in infancy and study of ointments in 27 children with food allergy].

Guillet, G; Guillet, M H

2000-10-01

A five month old child with atopic dermatitis developed contact dermatitis to almond with positive patch test, positive prick test, and class 4 anti-almond IgE. Focal lesions of persistent eczema were correlated with application of almond oil for 2 month on cheeks and buttocks. The child had not ingested almond and her mother did not report almond intake during her breast-feeding. This observation points to the problems of possible percutaneous sensitisation to food proteins. The study of skin ointments containing components of food origin in 27 food sensitized atopic patients confirm that the choice of an ointment for lesional skin is of importance.

Introduction: There is a general consensus that sleep disruption in children causes daytime behavioral deficits. It is unclear if sleep disruption in children with eczema has similar effects particularly after controlling for known comorbid disorders such as asthma and rhinitis. Methods: Parents of children (6-16 y) with eczema (n = 77) and healthy controls (n = 30) completed a validated omnibus questionnaire which included the Sleep Disturbance Scale for Children, Conners Parent Rating Scale-Revised (S), Child Health Questionnaire, Children's Dermatology Life Quality Index, and additional items assessing eczema, asthma, rhinitis, and demographics. Results: Compared to controls, children with eczema had a greater number of sleep problems with a greater percentage in the clinical range, lower quality of life, and higher levels of ADHD and oppositional behavior. They also had elevated rhinitis and asthma severity scores. Importantly, structural equation modelling revealed that the effect of eczema on the behavioral variables of Hyperactivity, ADHD Index, and Oppositional Behaviors were mediated through sleep with no direct effect of eczema on these behaviors. The comorbid atopic disorders of rhinitis and asthma also had independent effects on behavior mediated through their effects on sleep. Conclusions: The present findings suggest that the daytime behaviors seen in children with eczema are mediated independently by the effects of eczema, asthma, and rhinitis on sleep quality. These findings highlight the importance of sleep in eczematous children and its role in regulating daytime behavior. Citation: Camfferman D; Kennedy JD; Gold M; Martin AJ; Winwood P; Lushington K.

Reports on controlled trials on the efficacy and tolerability of sulfonated shale oils in atopic eczema are not available so far. The aim of this study was to investigate whether topically applied, specially prepared pale sulfonated shale oil (PSSO) cream is capable of improving symptoms/signs of mild to moderate atopic eczema in children more efficaciously than a corresponding vehicle cream. A total of 99 children suffering from mild to moderate atopic eczema were enrolled in this multicentre, randomized, vehicle-controlled study. Verum or vehicle cream was applied to the affected skin area three times a day over 4 weeks. As the primary outcome parameter served the reduction of the total score after 4 weeks of treatment, compared with the initial examination. Secondary outcome parameters were addressed as well. Tolerability was judged by investigators and patients/parents, and adverse events were documented. After 4 weeks of treatment, the total score declined from 13.4 ± 3.7 to 4.5 ± 7.4 score points in the verum group and from 13.0 ± 3.1 to 11.7 ± 8.6 score points in the vehicle group (P < 0.0001). The superiority of verum regarding total score was already apparent after a treatment period of 1 week (reduction by 5.6 ± 4.3 vs. 1.3 ± 5.9 score points; P < 0.0001). Tolerability was found superior at the end of the treatment in the verum when compared with the control group--both by investigators (P < 0.0001) and patients/parents (P = 0.0051). Pale sulfonated shale oil cream 4% is capable to treat mild to moderate atopic eczema in children more efficaciously than vehicle and is well tolerated. PSSO thus represents a valuable addition to our therapeutic armamentarium. PSSO should be considered in particular when valid alternatives for topical glucocorticoids are sought for. © 2010 The Authors.

OBJECTIVE--To determine whether the increased prevalence of childhood eczema in advantaged socioeconomic groups is due to increased parental reporting. DESIGN--Comparison of parental reports of eczema with visible eczema recorded by medical officers during a detailed physical examination. SETTING--National birth cohort study. SUBJECTS--8279 children from England, Wales, and Scotland born during 3-9 March 1958 and followed up at the ages of 7, 11, and 16. MAIN OUTCOME MEASURES--Prevalence of eczema according to parental report compared with medical officer's examination at the ages of 7, 11, and 16. RESULTS--Prevalence of both reported and examined eczema increased with rising social class at the ages of 7, 11, and 16 years. The point prevalence of examined eczema at age 7 was 4.8%, 3.6%, 3.6%, 2.4%, 2.2%, and 2.4% in social classes I, II, III non-manual, III manual, IV, and V respectively (chi 2 value for linear trend 12.6, P < 0.001). This trend persisted after adjustment for potential confounders such as region and family size and was not present for examined psoriasis or acne. CONCLUSIONS--Eczema is more prevalent among British schoolchildren in social classes I and II than those in lower classes. Exposures associated with social class are probably at least as important as genetic factors in the expression of childhood eczema. PMID:8173454

The role of timing and diversity of allergenic food introduction in the development of childhood allergic sensitization and atopic diseases is controversial. To examine whether timing and diversity of allergenic food introduction are associated with allergic sensitization, allergy and eczema in children until age 10 years. This study among 5,202 children was performed in a population-based prospective cohort. Timing (age ≤6 months vs. >6 months) and diversity (0, 1, 2 and ≥3 foods) of allergenic food (cow's milk, hen's egg, peanut, tree nuts, soy and gluten) introduction were assessed by questionnaires at ages 6 and 12 months. At age 10 years, inhalant and food allergic sensitization were measured by skin prick tests, and physician-diagnosed inhalant and food allergy by questionnaire. Data on parental-reported physician-diagnosed eczema were obtained from birth until age 10 years. Children introduced to gluten at age ≤6 months had a decreased risk of eczema (aOR (95% CI): 0.84 (0.72, 0.99)), compared with children introduced to gluten at age >6 months. However, timing of allergenic food introduction was not associated with allergic sensitization or physician-diagnosed allergy. Children introduced to ≥3 allergenic foods at age ≤6 months had a decreased risk of physician-diagnosed inhalant allergy (0.64 (0.42, 0.98)), compared with children not introduced to any allergenic food at age ≤6 months. However, diversity of allergenic food introduction was not associated with allergic sensitization, physician-diagnosed food allergy or eczema. Neither timing nor diversity of allergenic food introduction was consistently associated with childhood allergic sensitization, allergy or eczema.

Vitamin D and the Development of Atopic Eczema

PubMed Central

Palmer, Debra J.

2015-01-01

A “vitamin D hypothesis” has been proposed to explain the increased prevalence of eczema in regions with higher latitude. This review focuses on the current available evidence with regard to the possible effect of vitamin D on the development of atopic eczema. Observational studies have indicated a link between vitamin D status and eczema outcomes, including lower serum vitamin D levels associated with increased incidence and severity of eczema symptoms. Vitamin D is known to have a regulatory influence on both the immune system and skin barrier function, both critical in the pathogenesis of eczema. However heterogeneous results have been found in studies to date investigating the effect of vitamin D status during pregnancy and infancy on the prevention of eczema outcomes. Well-designed, adequately powered, randomised controlled trials are needed. The study design of any new intervention trials should measure vitamin D levels at multiple time points during the intervention, ultraviolet (UV) radiation exposure via the use of individual UV dosimeters, and investigate the role of individual genetic polymorphisms. In conclusion, the current available evidence does not allow firm conclusions to be made on whether vitamin D status affects the development of atopic eczema. PMID:26239464

Preeclampsia reflects an unusual increase in systemic inflammation during pregnancy. We studied associations between preeclampsia and asthma, allergy, and eczema in Copenhagen Prospective Studies on Asthma in Childhood 2000 (COPSAC 2000 ) and in national registries. COPSAC 2000 is a high-risk birth cohort of 411 Danish children. Asthma, allergy, and eczema were diagnosed prospectively, and lung function measured at age 1 month and 7 years. Sensitization was evaluated at age 6 months, 18 months, 4 years, and 6 years by skin prick tests and IgE measurements. The register-based cohort included 1.7 million children from Danish national registries in the 35-year period 1977-2012. Children born to mothers with preeclampsia were analyzed regarding risk of asthma, allergy, and eczema. In the COPSAC 2000 cohort, 5.6% (n = 23) were diagnosed with preeclampsia. Preeclampsia was associated with increased risk of treatment with inhaled corticosteroids at age 7 years (adjusted odds ratio, 4.01 [95% confidence interval (CI), 1.11-14.43]; P = 0.0337), increased bronchial responsiveness to methacholine (adjusted β-coefficient log-μmol, -0.80 [95% CI, -1.55 to -0.06]; P = 0.0348), and allergic rhinitis (adjusted odds ratio, 4.83 [95% CI, 1.58-14.78]; P = 0.0057) in the 7-year-old children. Furthermore, the children had an increased risk of sensitization to both aeroallergens and food allergens, and increased amount of total IgE during childhood. In the registry-based cohort, 3.7% (n = 62,728) were born to mothers with preeclampsia. Preeclampsia was associated with increased risk of asthma, eczema, and aeroallergen and food allergy, especially pronounced after a duration of preeclampsia of 14 days or more. Maternal asthma increased the risk of preeclampsia. Preeclampsia is a shared prenatal risk factor for asthma, eczema, and allergy in childhood pointing toward in utero immune programming of the child.

An altered compositional signature and reduced diversity of early gut microbiota are linked to development of allergic disease. We investigated the relationship between dominant Bifidobacterium species during the early post-natal period and subsequent development of allergic disease in the first year of life. Faecal samples were collected at age 1 week, 1 month and 3 months from 117 infants at high risk of allergic disease. Bifidobacterium species were analysed by quantitative PCR and terminal restriction fragment length polymorphism. Infants were examined at 3, 6 and 12 months, and skin prick test was performed at 12 months. Eczema was diagnosed according to the UK Working Party criteria. The presence of B. catenulatum at 3 months was associated with a higher risk of developing eczema (OR adj = 4.5; 95% CI: 1.56-13.05, p adj = 0.005). Infants colonized with B. breve at 1 week (OR adj = 0.29; 95% CI: 0.09-0.95, p adj = 0.04) and 3 months (OR adj = 0.15; 95% CI: 0.05-0.44, p adj = 0.00001) had a reduced risk of developing eczema. Furthermore, the presence of B. breve at 3 months was associated with a lower risk of atopic sensitization at 12 months (OR adj = 0.38; 95% CI: 0.15-0.98, p adj = 0.05). B. breve colonization patterns were influenced by maternal allergic status, household pets and number of siblings. Temporal variations in Bifidobacterium colonization patterns early in life are associated with later development of eczema and/or atopic sensitization in infants at high risk of allergic disease. Modulation of the early microbiota may provide a means to prevent eczema in high-risk infants. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

JOINT EFFECT OF PRENATAL EXPOSURE TO FINE PARTICULATE MATTER AND INTAKE OF PARACETAMOL (ACETAMINOPHEN) IN PREGNANCY ON ONSET OF ECZEMA IN EARLY CHILDHOOD. PROSPECTIVE BIRTH COHORT STUDY

Prenatal Paracetamol (Acetaminophen) has been associated with increased risk of allergic disease in early childhood, an association that could be due to increased altered susceptibility induced by air pollutants. The main goal of the study was to test the hypothesis that prenatal Paracetamol exposure increases the risk of developing eczema in early childhood and that this association is stronger for children who are exposed prenatally to higher concentrations of fine particulate matter (PM2.5). The study sample consisted of 322 women recruited from January 2001 to February 2004 in the Krakow inner city area who gave birth to term babies and completed 5-year follow-up. Paracetamol use in pregnancy was collected by interviews and prenatal personal exposure to over 48 hours was measured in all recruited women in the second trimester of PM2.5 pregnancy. After delivery, every three months in the first 24 months of the newborn’s life and every 6 months later, a detailed standardized face-to-face interview on the infant’s health was administered to each mother by a trained interviewer. During the interviews at each of the study periods after birth, a history of eczema was recorded. By Cox proportional hazard regression, prenatal exposure to Paracetamol increased the risk of eczema by 20% and PM2.5 by 6%, albeit non significantly. However, the the joint exposure to Paracetamol and higher prenatal PM2.5 was significant and doubled the risk of eczema symptoms (HR = 2.07, 95%CI: 1.01 – 4.34). The findings suggest that even very small doses of Paracetamol in pregnancy may affect the occurrence of allergy outcomes such as eczema in early childhood but only at the co-exposure to higher fine particulate matter.

The aim was to assess the impact of eczema on health-related quality of life in the population-based birth cohort BAMSE with 2,756 pre-adolescent children. All answered the following questions on self-perceived health; "How are you feeling?", "How healthy do you consider yourself to be?" and "How happy are you with your life right now?". Children with ongoing eczema answered the "Children's Dermatology Life Quality Index (CDLQI)" questionnaire. In total, 350 (12.7%) of the children had eczema. Girls with eczema reported impaired self-perceived health as evaluated in the 3 questions; adjusted OR 1.72 (95% CI 1.16-2.55), 1.89 (95% CI 1.29-2.76) and 1.69 (95% CI 1.18-2.42). Eczema among boys was not associated with impairment of self-perceived health. The mean CDLQI score was 3.98 (95% CI 3.37-4.58). Since eczema affects up to 20% of pre-adolescent girls, the findings have implications both for health care providers and for society as a whole.

There is a need for well-developed and validated questionnaires to measure patient reported outcomes. The Quality of Life in Hand Eczema Questionnaire (QOLHEQ) is such a validated instrument measuring disease-specific health-related quality of life in hand eczema patients. A re-validation of measurement properties is required before an instrument is used in a new population. With the objective of arriving at a guideline for translation and national validation of the QOLHEQ, we have developed the design of a reference study on how to adequately assess measurement properties of the QOLHEQ based on interdisciplinary discussions and current standards. We present a step-by-step guideline to assess translation (including cross-cultural adaptation), scale structure, validity, reproducibility, responsiveness, and interpretability. We describe which outcomes should be reported for each measurement property, and give advice on how to calculate these. It is also specified which sample size is needed, how to deal with missing data, and which cutoff values should be applied for the measurement properties assessed during the validation process. In conclusion, this guideline, presenting a reference validation study for the QOLHEQ, creates the possibility to harmonize the national validation of the various language versions of the QOLHEQ. © 2017 John Wiley & Sons A/S.

Several studies on avoidance of house-dust-mite (HDM) and cat allergens have been carried out, most of them in asthmatic patients and only a few in patients with atopic dermatitis (AD). No study so far has focused on which subgroup of AD patients benefits from avoidance measures. Forty adult patients with AD completed the 12-month avoidance study. They were divided into an active treatment (n = 22) and a placebo (n = 18) group. Active treatment comprised use of polyurethane-coated cotton encasings for bedding, and placebo use of cotton covers. Patients came for regular checkups during the 12-month period, when eczema severity was assessed and blood samples were analyzed for total IgE, HDM- and cat-specific IgE and soluble CD30 (sCD30) in serum. Dust samples were collected from mattresses before treatment and after 3, 6, and 12 months, and analyzed for content of HDM and cat allergen. Eczema severity decreased significantly in both groups (P < 0.001), with a more pronounced decrease in patients with active covers. The HDM exposure decreased significantly in the active treatment group (P < 0.001), and the levels of HDM-specific IgE were reduced (P<0.05). Exposure to cat allergens was unchanged in the active treatment group but decreased, albeit not significantly (P=0.19), in the placebo group. sCD30 levels were significantly reduced in both groups (P<0.001). Patients not sensitized to HDM allergens benefited from the bedcovers as much as sensitized patients. Occlusive bedding significantly reduced HDM exposure in bed (P<0.001) and eczema severity, and sCD30 levels decreased significantly (P<0.001). Patients not sensitized to HDM and not exposed to HDM allergens benefited equally from use of the bedcovers, a result which could be due to a reduction of other important allergens, superantigens, or irritants in bed. We therefore recommend the use of bedcovers as part of treatment for AD.

Atopic dermatitis (AD) affects health and quality of life and it has great impact on both health-care costs and costs to the society. The objective of this study was to develop a model to analyse the cost-effectiveness of a barrier-strengthening moisturizing cream as maintenance therapy compared with no treatment after initial treatment with betamethasone valerate in adult patients with AD in Sweden. A further aim was to apply a similar health-economic analysis for Denmark, Norway and Finland. A Markov simulation model was developed including data from three sources: (i) efficacy data from a randomized controlled trial including patients with moderate AD treated with either a moisturizing cream or no treatment, (ii) resource utilization and quality of life data, and (iii) unit prices from official price lists. A societal perspective was used and the analysis was performed according to treatment practice in Sweden. The model simulation was also applied for Denmark, Norway and Finland with inclusion of country-specific unit costs. Sensitivity analyses were performed to test the robustness of the results. The results from the present analyses of treatment for patients with moderate AD indicate that maintenance treatment with a moisturizing cream during eczema-free periods could be cost-effective in a societal perspective. Similar results were obtained for Sweden, Denmark, Norway and Finland. According to the analysis, treatment with a moisturizing cream was found to be a cost-effective option compared with no treatment in eczema-free periods in adult patients with AD in the four Nordic countries.

Evidence-based recommendations are available for the prevention of hand eczema among healthcare workers. However, the implementation of these recommendations is not always successful. To identify barriers and facilitators in the implementation of recommendations for the prevention of hand eczema among healthcare workers alongside a randomized controlled trial. A qualitative study was performed in which 19 healthcare workers were interviewed. The interview transcripts were open coded and also coded by means of a template by two researchers to identify relevant barriers and facilitators. Most barriers and facilitators reported for the recommendations were found at the level of the innovation (e.g. the recommendations), whereas for the guideline as a whole, multiple levels (socio-political, organization, user, and facilities) were identified. To enhance the implementation of recommendations for the prevention of hand eczema in a healthcare setting, having knowledge about these recommendations seems to be an important first step. In addition, maintaining the attention of the subject, testing the products beforehand and close collaboration with the infection control department might enhance implementation. Furthermore, it is important that the recommendations fit in with the work of the healthcare workers. When the implementation of the recommendations is prepared, these points should be taken into account. © 2015 The Authors. Contact Dermatitis published by John Wiley & Sons Ltd.

Eczema and cardiovascular risk factors in 2 US adult population studies.

Eczema is associated with high rates of sleep disturbance and quality-of-life impairment. These factors might have a negative impact on psychosocial development and behavior and could increase cardiovascular risk. We sought to determine whether adults with eczema have increased cardiovascular risk factors. We analyzed data for 27,157 and 34,525 adults aged 18 to 85 years from the 2010 and 2012 National Health Interview Survey. Adults with eczema had higher odds of ever smoking 100 cigarettes in their lifetime (survey logistic regression; adjusted odds ratio [aOR], 1.32; 95% CI, 1.18-1.47) and current smoking history (aOR, 1.28; 95% CI, 1.12-1.45), with significantly younger age of onset (survey linear regression; adjusted β, -0.58; 95% CI, -0.95 to -0.21). Eczema was also associated with greater odds of ever drinking 12 or more alcoholic beverages annually (aOR, 1.16; 95% CI, 1.03-1.31), including current intake of moderate (aOR, 1.33; 95% CI, 1.09-1.62) and heavier (aOR, 1.58; 95% CI, 1.23-2.03) amounts. Adults with a history of eczema had lower odds of daily vigorous activity (aOR, 0.79; 95% CI, 0.63-0.99) and lower frequency of vigorous activity in the past week (adjusted β, -0.46; 95% CI, -0.72 to -0.21) than did adults without a history of eczema. Those with eczema had a higher body mass index than did those without eczema (adjusted β, 0.86; 95% CI, 0.37-1.36), particularly a body mass index of 35 or more (aOR, 1.54; 95% CI, 1.16-2.05), and higher odds of hypertension (aOR, 1.48; 95% CI, 1.18-1.85), hypertension on 2 visits (aOR, 1.56; 1.22-1.99), and lifetime prediabetes (aOR, 1.71; 95% CI, 1.19-2.45). Finally, there were significant interactions between eczema and sleep disturbances such that eczema associated with fatigue, daytime sleepiness, or insomnia was associated with even higher odds of obesity, hypertension, hypertension on 2 visits, prediabetes, diabetes, and high cholesterol than eczema alone. We found that eczema in adults is a marker for cardiovascular risk, emphasizing the importance of behavioral modification and perhaps more aggressive interventions to better manage eczema.

Atopic eczema begins primarily in infancy or early childhood, and sleep loss due to night-time pruritus can have a considerable impact on patients' and parents' quality of life (QoL). In this study, infants (n = 196) with mild to severe atopic eczema were randomized 2:1, double-blind, to receive either pimecrolimus cream 1% (Elidel, Novartis Pharma, Nürnberg, Germany) or the corresponding vehicle bid for 4 wk, followed by a 12 wk, open-label phase and a 4 wk, treatment-free, follow-up period. The parents' QoL was measured at baseline and at the end of the double-blind phase, using the questionnaire 'QoL in Parents of Children with Atopic Dermatitis' (PQoL-AD), thus data presented here refer to the initial 4-wk treatment phase only. After 4 wk of double-blind treatment, an increase in the mean percentage change from baseline in eczema area and severity index of 71.5% was observed with pimecrolimus, compared with 19.4% with vehicle. The increase in efficacy was paralleled by the following mean percentage changes from baseline in the five domains of the questionnaire in pimecrolimus and vehicle, respectively: psychosomatic well-being: 14.6% vs. 6.2%; effects on social life: 6.7% vs. 2.3%; confidence in medical treatment: 10.0% vs. 3.7%; emotional coping: 16.1% vs. 6.5%; acceptance of disease: 19.6% vs. 7.0%. Analysis (ancova) of the dependent variable difference from baseline and the covariate baseline value revealed values of p < 0.05 for all five domains, despite the very short duration of the study. It is concluded that improvements in atopic eczema in infants achieved by treatment with pimecrolimus have a significant beneficial effect on the QoL of parents.

Epidemiological evidence regarding the effect of perinatal smoking exposure on atopic eczema in children continues to be inconclusive. The aim of this prospective prebirth cohort study was to investigate the association between prenatal smoking exposure and postnatal living with household smokers and the risk of atopic eczema in Japanese children aged 23 to 29 months. Study subjects were 1354 Japanese mother-child pairs. Information on the variables under study was obtained through questionnaires which were completed by mothers, first prior to delivery, then shortly after birth and subsequently around 4, 12, and 24 months after delivery. Eczema in the last 12 months was defined according to the criteria of the International Study of Asthma and Allergies in Childhood. Physician-diagnosed atopic eczema was considered present if reported by mothers. Compared with no perinatal smoking exposure, prenatal smoking exposure only was associated with an increased risk of physician-diagnosed atopic eczema (adjusted odds ratio = 7.11, 95% confidence interval: 1.43 to 27.8). Postnatal living with at least one household smoker only was not associated with the risk of physician-diagnosed atopic eczema; neither was the combination of both prenatal smoking exposure and postnatal living with at least one household smoker. No association was observed between perinatal smoking exposure status and the risk of eczema as defined according to the International Study of Asthma and Allergies in Childhood criteria. Our findings suggest that maternal smoking during pregnancy may increase the risk of atopic eczema in young children. In the present prebirth cohort study, we assessed the independent and additive effects of pre- and postnatal exposure to tobacco smoking on atopic eczema in children. Compared with no perinatal smoking exposure, prenatal smoking exposure only was significantly associated with an increased risk of atopic eczema. Postnatal smoking exposure only was not associated with the risk of atopic eczema; neither was the combination of both pre- and postnatal smoking exposure. This is the first epidemiological study to show a positive association between prenatal smoking exposure only and the risk of atopic eczema. © The Author 2016.

2016-05-27

Eczema, synonymous with atopic eczema or atopic dermatitis, is a chronic skin disease that has a similar impact on health-related quality of life as other chronic diseases. The proposed research aims to provide a comprehensive systematic assessment of the economic evidence base available to inform economic modelling and decision making on interventions to prevent and treat eczema at any stage of the life course. Whilst the Global Resource of Eczema Trials (GREAT) database collects together the effectiveness evidence for eczema, there is currently no such systematic resource on the economics of eczema. It is important to gain an overview of the current state of the art of economic methods in the field of eczema in order to strengthen the economic evidence base further. The proposed study is a systematic review of the economic evidence surrounding interventions for the prevention and treatment of eczema. Relevant search terms will be used to search MEDLINE, EMBASE, Database of Abstracts of Reviews of Effects, Cochrane Database of Systematic Reviews, Cochrane Central Register of Controlled Trials, National Health Service (NHS) Economic Evaluation Database, Health Technology Assessment, Cumulative Index to Nursing and Allied Health Literature, EconLit, Scopus, Cost-Effectiveness Analysis Registry and Web of Science in order to identify relevant evidence. To be eligible for inclusion studies will be primary empirical studies evaluating the cost, utility or full economic evaluation of interventions for preventing or treating eczema. Two reviewers will independently assess studies for eligibility and perform data abstraction. Evidence tables will be produced presenting details of study characteristics, costing methods, outcome methods and quality assessment. The methodological quality of studies will be assessed using accepted checklists. The systematic review is being undertaken to identify the type of economic evidence available, summarise the results of the available economic evidence and critically appraise the quality of economic evidence currently available to inform future economic modelling and resource allocation decisions about interventions to prevent or treat eczema. We aim to use the review to offer guidance about how to gather economic evidence in studies of eczema and/or what further research is necessary in order to inform this. PROSPERO CRD42015024633.

The authors followed the frequency of fragrance contact sensitization in Hungary in a multicentre study in the years 1998 and 1999. A total of 3,604 patients were tested with fragrance mix (FM), and positive reactions were observed in 294 (8.2%). In 160 FM hypersensitive patients, the study was continued with patch testing of the mix constituents (cinnamic alcohol, cinnamic aldehyde, eugenol, amyl cinnamic aldehyde, hydroxycitronellal, geraniol, isoeugenol, oak moss absolute). Of the patients tested, 70.6% produced positive reactions to the constituents. FM contact sensitization was mainly observed in female patients (74.4%). The incidence of contact urticaria in FM hypersensitive patients was 6.1%. Simultaneous patch test trials of other environmental contact allergens, in both early and late evaluations, mainly confirmed hypersensitivity reactions to balsams. Female dominance of hypersensitivity reactions observed during testing the individual components of the mix was striking (82.4%). In positive skin reactions, cinnamic alcohol, isoeugenol and oak moss provoked skin symptoms most frequently. We also tested the 104 patients who produced negative reactions to FM with the constituent individual allergens, with 11.9% positive incidence. The clinical symptoms of the patients were above all manifest in the form of contact eczema, located on the hands, face, eyelids and axillae. With this study, the authors, members of the Hungarian Contact Dermatitis Research Group, call attention to one of the most frequent allergens in the environment.

Objective Leave-on emollients form the mainstay of eczema treatment, but adherence is poor. We aimed to explore parents’/carers' views on effectiveness and acceptability of leave-on emollients for childhood eczema through secondary analysis of data from 2 qualitative data sets. Setting Study 1 recruited through mail-out from 6 general practices in southern England. Study 2 recruited from a feasibility trial of an intervention to support eczema self-care in 31 practices in the same area. Participants Study 1 included 28 interviews with carers of children aged ≤5 years with eczema. Study 2 included 26 interviews with carers of children aged ≤5 years with eczema. Methods Interviews followed semistructured guides: study 1 explored carers' understandings around eczema treatments in order to develop a web-based self-care support intervention; study 2 explored carers' understandings of eczema and eczema treatments after using the intervention. Interviews were carried out face to face or by telephone, audio-recorded and transcribed. Secondary analysis of data from both studies focused on views and experiences of emollient use. Data were analysed using an inductive thematic approach facilitated by NVivo V.10 software. Results In study 1, most participants felt emollients improved eczema but held mixed views about long-term use to prevent flare-ups. In study 2, where carers had used the web-based intervention, all participants held positive views about long-term emollient use. In both studies, participants expressed a range of preferences about emollient ‘thickness’; some felt that ‘thick’ emollients (ointments) were most effective, while others found these difficult to use. Carers described a process of ‘trial and error’, trying emollients suggested by professionals, friends and family, or bought over-the-counter. Carers expressed a need for understanding differences between products and their effective use. Conclusions Providing a rationale for long-term emollient use and choice of emollients could help improve adherence and help families gain more rapid control of eczema. PMID:27543590

Filaggrin gene (FLG) expression, particularly in the skin, has been linked to the development of the skin barrier and is associated with eczema risk. However, knowledge as to whether FLG expression in umbilical cord blood (UCB) is associated with eczema development and prediction is lacking. This study sought to assess whether FLG expression in UCB associates with and predicts the development of eczema in infancy. Infants enrolled in a birth cohort study (n=94) were assessed for eczema at ages 3, 6, and 12 months. Five probes measuring FLG transcripts expression in UCB were available from genomewide gene expression profiling. FLG genetic variants R501X, 2282del4, and S3247X were genotyped. Associations were assessed using Poisson regression with robust variance estimation. Area under the curve (AUC), describing the discriminatory/predictive performance of fitted models, was estimated from logistic regression. Increased level of FLG expression measured by probe A_24_P51322 was associated with reduced risk of eczema during the first year of life (RR=0.60, 95% CI: 0.38-0.95). In contrast, increased level of FLG antisense transcripts measured by probe A_21_P0014075 was associated with increased risk of eczema (RR=2.02, 95% CI: 1.10-3.72). In prediction models including FLG expression, FLG genetic variants, and sex, discrimination between children who will and will not develop eczema at 3 months of age was high (AUC: 0.91, 95% CI: 0.84-0.98). This study demonstrated, for the first time, that FLG expression in UCB is associated with eczema development in infancy. Moreover, our analysis provided prediction models that were capable of discriminating, to a great extent, between those who will and will not develop eczema in infancy. Therefore, early identification of infants at increased risk of developing eczema is possible and such high-risk newborns may benefit from early stratification and intervention. © 2017 John Wiley & Sons Ltd.

Background Worms may protect against allergy. Early-life worm exposure may be critical, but this has not been fully investigated. Objectives To investigate whether worms in pregnancy and in early childhood are associated with childhood eczema incidence. Methods The Entebbe Mother and Baby Study, an anthelminthic treatment trial, enrolled pregnant women between 2003 and 2005 in Uganda. Mothers were investigated for worms during pregnancy and children annually. Eczema was doctor-diagnosed from birth to age five years. A planned observational analysis was conducted within the trial cohort to investigate associations between worms and eczema. Results Data for 2345 live-born children were analysed. Hookworm was the most prevalent maternal worm (45%). Childhood worms were less prevalent. Eczema incidence was 4.68/100 person-years. Maternal hookworm was associated with reduced eczema incidence [adjusted hazard ratio (95% confidence interval), p-value: 0.71(0.51–0.99), 0.04] and modified effects of known risk factors for eczema: Dermatophagoides-specific IgE in children was positively associated with eczema incidence if the mother had no hookworm [2.72(1.11–6.63), 0.03], but not if the mother had hookworm [0.41(0.10–1.69), 0.22], interaction p-value = 0.03. Similar interactions were seen for maternal history of eczema {[2.87(1.31–6.27, 0.008) vs. [0.73(0.23–2.30), 0.60], interaction p-value = 0.05}, female gender {[1.82(1.22–2.73), 0.004 vs. [0.96(0.60–1.53), 0.87], interaction p-value = 0.04} and allergen-specific IgE. ChildhoodTrichuris trichiura and hookworm were inversely associated with eczema. Conclusions Maternal hookworm modifies effects of known risk factors for eczema. Mechanisms by which early-life worm exposures influence allergy need investigation. Worms or worm products, and intervention during pregnancy have potential for primary prevention of allergy.

Prevalence of childhood eczema and food sensitization in the First Nations reserve of Natuashish, Labrador, Canada

PubMed Central

2014-01-01

Background The Mushua Innu of Natuashish, Labrador, Canada seem to have a high rate of childhood eczema. Anecdotally this problem seems to be more common now than 20 years ago. There has been speculation that this could be related to food sensitization that may have arisen coincident with a move away from a traditional Innu diet. We undertook to assess the prevalence and severity of pediatric eczema in Natuashish (population 792), and investigate the level of sensitization to common food antigens. Methods Over a three-month period we performed a population survey of all children in the community from the ages of 2–12 inclusive. The one-year prevalence of eczema was assessed using the United Kingdom Working Party’s diagnostic criteria, and graded on the Nottingham Severity Scale. All children with eczema and twice as many age/sex matched controls were offered complete blood counts, total IgE, and food specific IgE levels for egg white, cow’s milk protein and wheat. Results One hundred and eighty two (95% of the eligible children) were assessed. Of the 182 children examined eczema was diagnosed in 30 (16.5%) - 22 females and 8 males. The majority of children with eczema (20/30) were classified as being in the moderate and severe category. Of the 22 with eczema and 40 controls who consented to venipuncture all but 3 had IgE levels above the lab's reference range. Food specific antibody assays showed that 32, 23, and 5 percent of children with eczema were sensitized to egg, milk, and wheat respectively. None of the controls were sensitized. Conclusions The children of Natuashish, Labrador have a high rate of eczema, much of it graded as moderate or severe. IgE levels were markedly elevated in children with and without eczema, with average values at least ten-fold higher than other populations. There is no evidence of an unusual amount of sensitization to egg, milk or wheat. PMID:24649812

The early occurrence of atopic dermatitis in infants may be influenced by urban air pollution. The aim of this study was to determine the relationship between incidences of infantile eczema in children under 2 years of age and urban outdoor environmental factors. A 11-year population-based study was conducted in retrospective design. The age/gender-adjusted incidence rates of infantile eczema were determined using the data of outpatient visits. We analysed 1965 cases with atopic dermatitis including infantile eczema in relation to the annual means of outdoor monitoring data from 2005 through 2015 in Minsk. Logistic regression and principal component analysis were performed to determine association between the annual means of air pollutants, meteorological variables and incidences of infantile eczema. Higher mean annual carbon monoxide, ammonia, formaldehyde, lead, particulate matter and ground-level ozone were associated with high incidence rates of infantile eczema both in boys and girls. Higher nitrogen dioxide was associated with high incidence rates of infantile eczema in girls 1-2 years of age and boys 0-2 years of age. There were identified by principal component analysis five combinations of pollutants and meteorological factors. High incidence rates of infantile eczema were associated with the combinations contained higher levels of air pollutants and ultraviolet index, or lower β-activity of the radionuclide-associated aerosols. The higher phenol and formaldehyde levels the higher incidence rates of infantile eczema were observed among boys 0-1 years of age and girls 1-2 years of age. The higher total column ozone with lower lead level was associated with low incidence rates of infantile eczema among boys and girls 1-2 years of age. Urban outdoor air pollutants and their combination with meteorological conditions may impact onset of infantile eczema in both genders. © 2018 European Academy of Dermatology and Venereology.

Epidemiological studies associated with breastfeeding have provided conflicting results about whether it is preventive or a risk factor for atopic eczema in children. The current prospective study investigated the relationship between breastfeeding and the risk of atopic eczema in Japan. A birth cohort of 763 infants was followed. The first survey during pregnancy and the second survey between 2 and 9 months postpartum collected information on potential confounding factors and atopic eczema status. Data on breastfeeding and symptoms of atopic eczema were obtained from questionnaires in the third survey from 16 to 24 months postpartum. The following variables were a priori selected as potential confounders: maternal age, maternal and paternal history of asthma, atopic eczema, and allergic rhinitis, indoor domestic pets (cats, dogs, birds, or hamsters), family income, maternal and paternal education, maternal smoking during pregnancy, baby's sex, baby's birth weight, baby's older siblings, household smoking in the same room as the infant, and time of delivery before the third survey. In the third survey, 142 infants (18.6%) were revealed to have developed atopic eczema based on criteria of the International Study of Asthma and Allergies in Childhood. In an overall analysis, neither exclusive nor partial breastfeeding was significantly related to the risk of atopic eczema. After excluding 64 infants identified with suspected atopic eczema in the second survey, both exclusive breastfeeding for 4 months or more and partial breastfeeding for 6 months or more were independently associated with an increased risk of atopic eczema only among infants with no parental history of allergic disorders [multivariate odds ratios were 2.41 (95% confidence interval, 1.10-5.55) and 3.39 (95% confidence interval, 1.20-12.36), respectively]. The authors found that, overall, neither exclusive nor partial breastfeeding had a strong impact on the risk of atopic eczema. However, a parental allergic history may affect the risk.

To determine whether installation of an ion-exchange water softener in the home could improve atopic eczema in children and, if so, to establish its likely cost and cost-effectiveness. An observer-blind, parallel-group randomised controlled trial of 12 weeks duration followed by a 4-week observational period. Eczema was assessed by research nurses blinded to intervention at baseline, 4 weeks, 12 weeks and 16 weeks. The primary outcome was analysed as intent-to-treat, using the randomised allocation rather than actual treatment received. A secondary per-protocol analysis excluded participants who failed to receive their allocated treatment and who were deemed to be protocol violators. Secondary and primary care referral centres in England (UK) serving a variety of ethnic and social groups and including children living in both urban and periurban homes. Three hundred and thirty-six children (aged 6 months to 16 years) with moderate/severe atopic eczema, living in homes in England supplied by hard water (≥ 200 mg/l calcium carbonate). Participants were randomised to either installation of an ion-exchange water softener plus usual eczema care (group A) for 12 weeks or usual eczema care alone (group B) for 12 weeks. This was followed by a 4-week observational period, during which water softeners were switched off/removed from group A homes and installed in group B homes. Standard procedure was to soften all water in the home, but to provide mains (hard) water at a faucet-style tap in the kitchen for drinking and cooking. Participants were therefore exposed to softened water for bathing and washing of clothes, but continued to drink mains (hard) water. Usual care was defined as any treatment that the child was currently using in order to control his or her eczema. New treatment regimens used during the trial period were documented. Primary outcome was the difference between group A and group B in mean change in disease severity at 12 weeks compared with baseline, as measured using the Six Area, Six Sign Atopic Dermatitis (SASSAD) score. This is an objective severity scale completed by blinded observers (research nurses) unaware of the allocated intervention. Secondary outcomes included use of topical medications, night-time movement, patient-reported eczema severity and a number of quality of life measures. A planned subgroup analysis was conducted, based on participants with at least one mutation in the gene encoding filaggrin (a protein in the skin thought to be important for normal skin barrier function). Target recruitment was achieved (n = 336). The analysed population included 323 children who had complete data. The mean change in primary outcome (SASSAD) at 12 weeks was -5.0 [standard deviation (SD) 8.8] for the water softener group (group A) and -5.7 (SD 9.8) for the usual care group (group B) [mean difference 0.66, 95% confidence interval (CI) -1.37 to 2.69, p = 0.53]. The per-protocol analysis supported the main analysis, and there was no evidence that the treatment effect varied between children with and without mutations in the filaggrin gene. No between-group differences were found in the three secondary outcomes that were assessed blindly (use of topical medications; night-time movement; proportion showing reasonable, good or excellent improvement). Small, but statistically significant, differences in favour of the water softener were found in three of the secondary outcomes that were assessed by participants [Patient-Oriented Eczema Measure (POEM); well-controlled weeks (WCWs); Dermatitis Family Index (DFI)]. The results of the economic evaluation, and the uncertainty surrounding them, suggest that ion-exchange water softeners are unlikely to be a cost-effective intervention for children with atopic eczema from an NHS perspective. Water softeners provided no additional benefit to usual care in this study population. Small, but statistically significant, differences were found in some secondary outcomes as reported by parents, but it is likely that such improvements were the result of response bias. Whether or not the wider benefits of installing a water softener in the home are sufficient to justify the purchase of a softener is something for individual householders to consider on a case-by-case basis. This trial demonstrated overwhelming demand for non-pharmacological interventions for the treatment of eczema, and this is something that should be considered when prioritising future research in the field.

Of 656 asthmatic patients referred specifically for allergy assessments, 544 (84 percent) gave positive immediate skin prick tests to at least one of 22 common allergens used routinely. Comparison of these skin test positive patients with the 102 (16 percent) who were skin test negative showed a number of significant differences. The majority of the skin test positive patients (52 percent) were less than 10 years old at the time of onset of the asthma, whereas, of the skin test negative patients, 56 percent were aged over 30 years at the time of onset. Seventy per cent report rhinitis compared with 48 per cent of the skin test negative patients, and 29 per cent reported infantile eczema compared with 9 per cent. Symptoms attributed to house dust, pollens, and animals were noted two to three times more frequently by the skin test positive patients, while corticosteroid drugs had been used more commonly by the skin test negative patients (45 percent compared with 35 percent). No significant differences were observed with the other factors studied, namely, history of urticaria or angio-oedema, family history of "allergic" disease, and awareness of sensitivity to foods, aspirin or penicillin. Prick test reactions in the skin test positive patients were most commonly seen to house dust or the acarine mite, Dermatophagoides farinae (82 percent), followed by pollens (66 percent), animal danders (38 percent), foods (16 percent), Aspergillus fumigatus (16 percent), and other moulds (21 percent). There was a highly significant association of positive history with positive prick test for all allergens studied. Images PMID:1168378

Methylmethacrylate was first reported in 1941 as a cause of contact dermatitis. Since then, occupational contact allergies to acrylates in dentistry, orthopedic surgery, printing industry and industry have been reported, but few reports are found in the literature as a consequence of the contact with sculptured artificial acrylic nails which are increasingly popular. We describe here 3 patients with contact allergy to acrylates in artificial sculptured nails. Patch tests were performed with the Portuguese baseline series of contact allergens and an extended series of acrylates were applied. In particular, we tested three female patients with allergic contact dermatitis from sculptured acrylic nails. Two of these patients were both customers and also technical nail beauticians. Two patients developed periungual eczema; one presented only with face and eyelid dermatitis had no other lesions. The tests showed positive reaction to 2-hydroxyethylmethacrylate (2-HEMA) and 2-hydroxypropylmethacrylate (2-HPMA) in all the three patients. Our cases demonstrate the variety of clinical presentations of allergic contact dermatitis from acrylic sculptured nails. They show the need to warn patients of persistent and sometimes permanent side effects of these products. They also emphasize the importance of cosmetic ingredient labeling. PMID:25386316

There is a lack of information on the prevalence, severity and risk factors of asthma, rhinitis and eczema in Chinese children. To establish baseline data for a major longitudinal study of factors affecting asthma, rhinitis and eczema in a large group of children from the industrialized city of Shijiazhuang, China. We used the International Study of Asthma and Allergies in Childhood questionnaire and studied 10 338 children, ages 6-18, from Shijiazhuang. The prevalence of childhood asthma, rhinitis and eczema is 1.2%, 13.5% and 11.8%, respectively. Boys had higher prevalence of these conditions than girls and younger children had higher prevalence of asthma and eczema but lower prevalence of rhinitis than older children. Breastfed children had lower prevalence of asthma and rhinitis, but not eczema, than non-breastfed children. Overweight children had higher prevalence of asthma and rhinitis than those who were not overweight. Children exposed to paternal smoking had higher prevalence of rhinitis and eczema than those not exposed; children exposed to pets had higher prevalence of asthma and rhinitis than those not exposed. The prevalence of asthma in this study group is low, but the prevalence of rhinitis is high, and could be considered a major public health problem. The prevalence of asthma, rhinitis and eczema is generally higher in boys and younger children generally have higher prevalence of asthma and eczema but lower prevalence of rhinitis. Exposure to pets is a risk factor for rhinitis, being overweight is a risk factor for asthma and rhinitis, and exposure to parental smoking is a risk factor for asthma, rhinitis and eczema in these children.

There is limited information on clinical manifestations of atopic eczema (AE) and non-AE in teenagers. To describe the characteristics of adolescent eczema in the general population and to identify potential differences between AE and non-AE in teenagers. Overall, 3108 teenagers were included from the population-based BAMSE cohort and 2529 of these teenagers provided blood samples for analysis of specific IgE. At age 16 years, the teenagers answered questionnaires regarding the symptoms of eczema, asthma and rhinitis for the previous year. The prevalence of eczema in adolescence was 9·6% (n = 297). More girls than boys had eczema (12·5% vs. 6·5%; P < 0·001). The age at onset was usually within the first 2 years of life (48·8%), but onset in adolescence was also common (25·6%). Eczema was mild in 72·7% of cases, moderate in 16·8% and severe in 10·4%. Body folds were most frequently affected (73·4%). More than half of the teenagers with eczema had AE (59%). The teenagers with AE had more severe and more chronic eczema. Onset in infancy was most common in AE and onset in adolescence was most common in non-AE. There were no major differences in location or seasonal variance between AE and non-AE in adolescence. AE is more common than non-AE among teenagers. More than one in four teenagers with eczema has moderate-to-severe disease. Onset in adolescence is common, especially for non-AE. AE in adolescence has an earlier onset and is more chronic and more severe than non-AE. © 2015 British Association of Dermatologists.

Today, many therapies are available for the treatment of psoriasis and eczema. One of the oldest topical therapies is coal tar. Coal tar has been used for decades, but over the past years, the use of coal tar has decreased for several reasons, including the supposed carcinogenicity of coal tar. We investigated the current and past treatment policies for psoriasis and eczema with special emphasis on the use of tar products; a postal survey was conducted among all dermatologists in two European countries: the Netherlands (n = 360) and the Flemish speaking part of Belgium (Flanders) (n = 328). This study was conducted as part of the ongoing LATER-study ("Late effects of coal tar treatment in eczema and psoriasis; the Radboud study"). All practising dermatologists received a questionnaire. Dermatologists were asked to describe their treatment policies in mild/moderate psoriasis, severe psoriasis, mild/moderate eczema and severe eczema. The response rate to the questionnaire was 62.5% for the Dutch dermatologists and 45.7% for the Flemish dermatologists. Almost all dermatologists prescribe topical corticosteroids. In eczema, most of the dermatologists prescribe the recently introduced calcineurin inhibitors (95%). Coal tar is a second choice topical therapy. Dutch dermatologists mainly use tar in the treatment of eczema (72% vs. 48% in Flanders), whereas in Flanders, tar is mainly prescribed in psoriasis (60% vs. 41% in Holland). Flemish dermatologists very frequently prescribe PUVA in psoriasis (93% vs. 63%). Topical treatment, especially topical corticosteroids, is the mainstay in psoriasis and eczema. Coal tar still is an important (second choice) therapy for the topical treatment of psoriasis and eczema, but its use varies from country to country. Despite the carcinogenicity of PUVA, this photochemotherapy is frequently prescribed by dermatologists, mainly in Flanders.

Eczema is a common chronic inflammatory disease of the skin. Studies suggest differences in disease prevalence and severity by race/ethnicity. Our knowledge of health care utilization for eczema among different racial/ethnic groups remains limited. To evaluate health care utilization for childhood eczema among different racial/ethnic groups in the United States. We performed a cohort study of non-Hispanic white (reference), non-Hispanic black, and Hispanic white individuals under the age of 18 years with caregiver-reported eczema (N = 2043) pooled from the 2-year longitudinal cohorts of the 2001-2013 Medical Expenditure Panel Surveys. Health care utilization outcomes were evaluated over the 2-year follow-up period by race/ethnicity using multivariable regression. Among all children with eczema, non-Hispanic blacks were less likely than whites to report an ambulatory visit for eczema (adjusted odds ratio [OR adj ] 0.69; 95% confidence interval [CI] 0.51-0.92). Among those with ≥1 ambulatory visit for eczema, non-Hispanic blacks reported more visits (adjusted incidence rate ratio [IRR adj ] 1.68; 95% CI 1.10-2.55) and prescriptions (IRR adj 1.22; 95% CI 1.01-1.46) than whites and were more likely than whites to report a dermatology visit (OR adj 1.82; 95% CI 1.06-3.14) for eczema. We used caregiver- or self-reported data. Our findings suggest disparities in health care utilization for eczema among non-Hispanic black children despite utilization patterns suggestive of more severe disease.

Factors accounting for the association between anxiety and depression, and eczema: the Hordaland health study (HUSK)

PubMed Central

2010-01-01

Background The association between anxiety and depression, and eczema is well known in the literature, but factors underlying this association remain unclear. Low levels of omega-3 fatty acids and female gender have been found to be associated with both depression and eczema. Somatization and health anxiety are known to be associated with anxiety and depression, further, somatization symptoms and health anxiety have also been found in several dermatological conditions. Accordingly, omega-3 fatty acid supplement, female gender, somatization and health anxiety are possible contributing factors in the association between anxiety and depression, and eczema. The aim of the study is to examine the relevance of proposed contributing factors for the association between anxiety and depression, and eczema, including, omega-3 fatty acid supplement, female gender, health anxiety and somatization. Methods Anxiety and depression was measured in the general population (n = 15715) employing the Hospital Anxiety and Depression Scale (HADS). Information on eczema, female gender, omega-3 fatty acid supplement, health anxiety and somatization was obtained by self-report. Results Somatization and health anxiety accounted for more than half of the association between anxiety/depression, and eczema, while the other factors examined were of minor relevance for the association of interest. Conclusions We found no support for female gender and omega-3 fatty acid supplement as contributing factors in the association between anxiety/depression, and eczema. Somatization and health anxiety accounted for about half of the association between anxiety/depression, and eczema, somatization contributed most. The association between anxiety/depression, and eczema was insignificant after adjustment for somatization and health anxiety. Biological mechanisms underlying the mediating effect of somatization are yet to be revealed. PMID:20412596

Atopic eczema (AE) is a common dermatological condition that causes significant problems in everyday life and high levels of illness-related stress in substantial proportions of patients. The extent to which adult AE is associated with clinically relevant psychiatric morbidity is unclear. To investigate the association between adult AE and major psychiatric/psychosomatic disorders. Case-control study utilizing the GKV database Saxony, an interdisciplinary administrative outpatient database from Germany. All patients documented as having AE at least twice within the study period (2003-2004) (n = 3769, mean age 44 years) were individually matched by age and sex to 3769 controls without AE. Logistic regression models were fitted to investigate the relationship of AE with affective, stress-related, behaviour and schizophrenic disorders, considering sociodemographic characteristics, consulting behaviour and allergic comorbidities as potential confounding factors. Eczema was independently associated with affective [adjusted odds ratio (OR) 1.42, 95% confidence interval (CI) 1.13-1.79], stress-related (OR 1.55, 95% CI 1.35-1.77), behaviour (OR 1.52, 95% CI 1.03-2.23) and schizophrenic disorders (OR 2.12, 95% CI 1.22-3.71). For each psychiatric condition the likelihood of being affected significantly increased with each physician visit due to AE, suggesting that the risk of psychiatric comorbidity increases with the severity of AE. This study indicates psychiatric comorbidity of adults with AE. Collaboration between dermatologists and mental health specialists may optimize medical care for a significant subgroup of patients with AE.

Food and environmental allergies.

Immunoglobulin E-mediated allergic responses to food and environmental allergens can cause symptoms ranging from mild allergic rhinitis and rashes to gastrointestinal distress and, most seriously, anaphylaxis. The diagnosis can be difficult, as it relies on complex interplay between patient history and diagnostic tests with low specificity. Adding to the difficulty in confirming the diagnosis is an increased public interest in food intolerances, which can be inappropriately attributed to an allergic response. Treatment of allergic diseases with avoidance strategies and pharmacologic treatments can improve quality of life and control of other chronic conditions, such as asthma and eczema.

[Atopic dermatitis and domestic animals].

Song, M

2000-09-01

Several arguments are raised attributing to aeroallergens an important role in atopic dermatitis. The aeroallergens that penetrate the epidermis could be fixed by IgE on the Langerhans cells and then induce a cellular mediator reaction comparable to that of allergic contact eczema. Patch tests have been developed to evaluate the role of aeroallergens (dust mites, animal dander, etc.). Preventive anti-dust mites measures in the home of atopic patients are recommended. Eviction of domestic animals (cat, dog, etc.) or avoidance measures for animal dander in the home can produce improvement in atopic dermatitis. Oral specific immunotherapy is being validated as a treatment for this disease.

Environmental irritants are important risk factors for skin diseases, but little is known about the influence of environmental factors on eczema incidence. In this time-series study, our objective was to examine the associations of environmental factors with outpatient visits for eczema. Daily outpatient visits between 2007 and 2011 (1826 days) were collected from Huashan Hospital in Shanghai, China. We used an overdispersed generalized additive model to investigate the short-term association between environmental factors and outpatient visits for eczema. Daily outpatient visits for eczema were significantly associated with air pollution and meteorological factors. For example, a 10 μg/m³ increase of 7-day (lag 06) average concentrations of PM 10 (particulate matter no greater than 10 microns), SO₂, NO₂ was associated with 0.81% (95% confidence intervals (CI) 0.39%, 1.22%), 2.22% (95% CI: 1.27%, 3.16%) and 2.31% (95% CI: 1.17%, 3.45%) increase in outpatient visits for eczema, respectively. A 10 °C elevation of temperature on lag 0 day were associated with 8.44% (95% CI: 4.66%, 12.22%) increase in eczema visits, whereas 10 unit decrease of 7-day average relative humidity were associated with 10.86% (95% CI: 8.83%, 12.89%) increase in eczema visits. This study provided clear evidence of ambient air pollution, high temperature and low relative humidity on increasing the incidence of eczema in Shanghai, China.

There is strong evidence to support a genetic predisposition to eczema and more recently studies have suggested that probiotics might be used to prevent eczema by modifying the expression of putative allergy-associated genes. The aim of this present study was to investigate whether two probiotics, Lactobacillus rhamnosus HN001 (HN001) and Bifidobacterium animalis subsp. lactis HN019 (HN019), can modify the known genetic predisposition to eczema conferred by genetic variation in the Toll-like receptor (TLR) genes in a high-risk infant population. We selected 54 SNPs in the Toll-like receptor genes. These SNPs were analysed in 331 children of sole European ancestry as part of a double-blind, randomized, placebo-controlled trial examining the effects of HN001 and HN019 supplementation on eczema development and atopic sensitization. The data showed that 26 TLR SNPs interacted with HN001 resulting in a significantly reduced risk of eczema, 18 for eczema severity as defined by SCORAD ≥ 10 and 20 for atopic sensitization compared to placebo. There were only two SNPs that interacted with HN019 resulting in a reduced risk of eczema, eczema severity or atopy. This is the first study to show that the negative impact of specific TLR genotypes may be positively affected by probiotic supplementation. HN001 exhibits a much stronger effect than HN019 in this respect. © 2015 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Eczema is a common childhood ailment responsible for a considerable disease burden. Both timing of introduction to solid food and allergenic food are believed to be related to childhood eczema. Despite the growing body of evidence, the relationship between timing of any solid food introduction (allergenic and/or non-allergenic) and development of eczema has not previously been systematically reviewed. PubMed and EMBASE databases were searched using food and eczema terms. Two authors selected papers according to the inclusion criteria and extracted information on study characteristics and measures of association. Meta-analyses were performed after grouping studies according to the age and type of exposure. A total of 17 papers met the inclusion criteria, reporting results from 16 study populations. Of these, 11 were cohort studies, 2 case-controls, 1 cross-sectional study and 2 randomized controlled trials. Limited meta-analyses were performed due to heterogeneity between studies. Timing of solid food introduction was not associated with eczema. One randomized controlled trial provided weak evidence of an association between early allergenic (around 4 months) food introduction and reduced risk of eczema. The available evidence is currently insufficient to determine whether the timing of introduction of any solid food influences the risk of eczema. © 2018 John Wiley & Sons Ltd.

Hand eczema is common in the nursing profession, and has been reported widely in various parts of the world. The aim of this study was to determine the prevalence and severity of hand eczema among nurses working in a regional hospital in Hong Kong, as well as its psychosocial impact and any possible associated risk factors. The study took the form of a self-report questionnaire survey; 1240 nurses in a regional hospital were asked to participate in the survey by completing the questionnaire and returning it anonymously within 2 weeks. Seven hundred and twenty-four nurses returned the questionnaire (a response rate of 59%). The prevalence of hand eczema among the respondents was 22.1% (160/724). More than 90% had moderate to severe hand eczema. Itchiness and dryness were the most common symptoms. Occupational work, housework, mood, social activities and sleep were particularly affected. Multinomial logistic regressions showed that a personal or family history of atopy and a hand washing frequency of >20 times per day were independent risk factors for hand eczema. Hand eczema is common and severe among Hong Kong nurses. The results of this study suggest that hand eczema is an important problem for nurses and that preventive measures should be emphasized. © 2011 John Wiley & Sons A/S.

Eczema is a common skin condition that impairs children's daily life activities and quality of life. Previous research shows that gut microbiome composition plays an important role in the development of eczema. The present review summarizes evidence on environmental factors related to altered gut microbiota in children with eczema. We searched Medline, PubMed, Embase, and the Cochrane database of Systematic Reviews through October 2015. The search strategy focused on articles published in peer-reviewed, English-language journals with no publication year limit. Only original studies and review articles that reported environmental factors on gut microbiome specific to eczema were included in this review. We selected six studies (total 1990 participants) for full review and identified that the composition of gut microbiota specific to eczema could be influenced by the following environmental factors: length of gestation, mode of delivery, type of feeding, method of treatment, number of older siblings, and other lifestyle factors. There has been inconsistent empirical evidence as to the modulatory effects of gut microbiota on immunological functions in children with eczema. Further research on the environmental-host-microbial interaction is needed to develop a strong base of knowledge for the development and implementation of prevention strategies and policies for eczema.

The objective of this study was to investigate the prevalence and severity of asthma, rhinitis, and atopic eczema in schoolchildren from southern Brazil. A cross-sectional study was carried out with the International Study of Asthma and Allergies in Childhood phase III written questionnaire. The questionnaire was self-applied by 2,948 randomly selected schoolchildren aged 13 to 14 years. The lifetime prevalence rates of symptoms were as follows: wheezing, 40.8%; rhinitis, 40.7%; eczema, 13.6%; self-reported asthma, 14.6%; rhinitis, 31.4%; eczema, 13.4%. Rhinitis was reported by 55% of adolescents with current asthma (60% females vs 46.9% males). Girls 13 to 14 years of age had higher prevalence rates of asthma, rhinitis, and eczema than boys had. Atopic eczema was reported by 42.7% of girls and 31.4% of boys with asthma. The prevalence rates were statistically significant for symptoms of asthma, rhinitis, and atopic eczema in females. However, there were no statistically significant differences between the sexes in regard to reported asthma and bronchospasm induced by exercise. PMID:20529214

Background The role of timing and diversity of allergenic food introduction in the development of childhood allergic sensitization and atopic diseases is controversial. Objective To examine whether timing and diversity of allergenic food introduction are associated with allergic sensitization, allergy and eczema in children until age 10 years. Materials and methods This study among 5,202 children was performed in a population-based prospective cohort. Timing (age ≤6 months vs. >6 months) and diversity (0, 1, 2 and ≥3 foods) of allergenic food (cow's milk, hen's egg, peanut, tree nuts, soy and gluten) introduction were assessed by questionnaires at ages 6 and 12 months. At age 10 years, inhalant and food allergic sensitization were measured by skin prick tests, and physician-diagnosed inhalant and food allergy by questionnaire. Data on parental-reported physician-diagnosed eczema were obtained from birth until age 10 years. Results Children introduced to gluten at age ≤6 months had a decreased risk of eczema (aOR (95% CI): 0.84 (0.72, 0.99)), compared with children introduced to gluten at age >6 months. However, timing of allergenic food introduction was not associated with allergic sensitization or physician-diagnosed allergy. Children introduced to ≥3 allergenic foods at age ≤6 months had a decreased risk of physician-diagnosed inhalant allergy (0.64 (0.42, 0.98)), compared with children not introduced to any allergenic food at age ≤6 months. However, diversity of allergenic food introduction was not associated with allergic sensitization, physician-diagnosed food allergy or eczema. Conclusion Neither timing nor diversity of allergenic food introduction was consistently associated with childhood allergic sensitization, allergy or eczema. PMID:29176842

Rural residence is protective against atopy and wheeze-rhinitis-eczema symptoms in developed countries, an effect attributed to farming and poor hygiene exposures. There are few data from developing countries addressing this question. We compared atopy and wheeze-rhinitis-eczema symptoms between urban and rural Ecuador, and explored the effects of farming and poor hygiene exposures. We performed cross sectional studies of schoolchildren living in rural and urban Ecuador. Data on symptoms and farming/hygiene exposures were collected by parental questionnaire, atopy by allergen skin prick test reactivity and geohelminth infections by stool examinations. Among 2526 urban and 4295 rural schoolchildren, prevalence was: atopy (10.0% vs 12.5%, p=0.06), wheeze (9.4% vs 10.1%, p=0.05), rhinitis (8.1% vs 6.4%, p=0.02) and eczema (5.9% vs 4.7%, p=0.06). A small proportion of symptoms were attributable to atopy (range 3.9-10.7%) with greater attributable fractions for respiratory symptoms observed in urban schoolchildren. Respiratory symptoms were associated with poor hygiene/farming exposures: wheeze with lack of access to potable water; and rhinitis with household pets, no bathroom facilities and contact with large farm animals. Birth order was inversely associated with respiratory symptoms. Area of residence and atopy had few effects on these associations. Urban schoolchildren living in Ecuador have a similar prevalence of atopy, eczema and wheeze but a higher prevalence of rhinitis compared with rural children. Some farming and poor hygiene exposures were associated with an increase in the prevalence of wheeze or rhinitis while birth order was inversely associated with these symptoms.

Background Atopic dermatitis (AD) is associated with multiple comorbid conditions, such as asthma and food allergy. We sought to determine the impact of eczema severity on the development of these disorders and other non-atopic comorbidities in AD. Methods We used the 2007 National Survey of Children's Health, a prospective questionnaire-based study of a nationally representative sample of 91,642 children age 0-17 years. Prevalence and severity of eczema, asthma, hay fever and food allergy, sleep impairment, healthcare utilization, recurrent ear infections, visual and dental problems were determined. Results In general, more severe eczema correlated with poorer overall health, impaired sleep and increased healthcare utilization, including seeing a specialist, compared to children with mild or moderate disease (Rao-Scott Chi-square, P<0.0001). Severe eczema was associated with higher prevalence of comorbid chronic health disorders, including asthma, hay fever and food allergies (P<0.0001). In addition, the severity of eczema was directly related to the severity of the comorbidities. These associations remained significant in multivariate logistic regression models that included age, sex and race/ethnicity. Severe eczema was also associated with recent dental problems, including bleeding gums (P<0.0001), toothache (P=0.0004), but not broken teeth (P=0.04) or tooth decay (P=0.13). Conclusions These data indicate that severe eczema is associated with multiple comorbid chronic health disorders, impaired overall health and increased healthcare utilization. Further, these data suggest that children with eczema are at risk for decreased oral health. Future studies are warranted to verify this novel association. PMID:23773154

Skin conditions such as psoriasis and eczema negatively impact the patient's quality of life; the primary goal of topical treatments is to minimize the disease-specific symptoms. This case report discusses the management of two refractory psoriasis skin lesions in an adult male using a topical compounded formula. The psoriasis symptoms were assessed quantitatively using two validated research instruments, the Psoriasis Symptom Inventory, and an adapted Numeric Rating Scale. A qualitative assessment was also performed by evaluating the digital photographs taken by the patient during the course of treatment. The compounded formula containing zinc pyrithione, clobetasol propionate, and cyanocobalamin in the Professional Compounding Centers of America's proprietary base PCCA XemaTop, applied topically for three weeks, significantly reduced the patient's self-reported psoriasis symptoms and improved his overall condition by 81.2%. This successful case report is important evidence for healthcare professionals when considering new, innovative topical compounded formulas for managing skin conditions such as psoriasis and eczema.

[Compositae dermatitis].

PubMed

Jovanović, Marina; Poljacki, Mirjana

2003-01-01

Compositae dermatitis is an allergic contact dermatitis caused by plant species of the Compositae family. The first report of a cutaneous reaction to the Chrysanthemum genus was made by Howe JS in 1887. In 1895 Maiden JH reported about skin lesions among men working with Tagetes minuta. Case reports of contact allergic-ragweed dermatitis appeared in the American literature as early as 1919. The North American feverfew--Parthenium Hysterophorus was brought to India from America in 1956 and it caused thousands of cases of so-called parthenium dermatitis. Ragweed and parthenium dermatitis became prototypes for the classic, so-called "airborne" Compositae dermatitis, that affects primarily exposed skin surfaces, and produces a universal erythroderma. The frequency of contact allergy to Compositae in Europe is higher than previously believed. It occurs most frequently in middle-aged and elderly persons, but also in all age groups. During the two past decades a more equal sex ratio has been established. The prevalence varies from 0.7-1.4% in the general population, up to 4.5% among occupationally exposed persons. Compositae allergy is among the top ten contact sensitivities in Europe. In North Europe plants were the cause of 4.4% cases of occupational allergic contact dermatitis. ETIOLOGY AND PATHOGENESIS: Among cultivated Compositae plants, Chrysanthemum is considered to be a major sensitizer in Europe (60%). Among the edible types, it is lettuce--Lactuca sativa and endive Cichorium endivia (20-30%), and wild-growing feverfew--Tanace--tum parthenium (70-90%), tansy--Tanacetum vulgare (54%), and dandelion--Taraxacum officinale (65%). Sesquiterpene lactones are the main sensitizers of the Compositae family. Other components, thiophenes and acetylenes are said to elicit only phytophotodermatitis, but recent studies have demonstrated that some thiophenes and benzofuran derivates possess not only phototoxic activity, but also sensitizing properties. Photosensitivity is present in 22-75% Compositae sensitive individuals. Extracts from Compositae are known to be phototoxic in vitro. Photoreactivity of alpha-methylene-gamma-la-ctone group of sesquiterpene-lactone directed towards the DNA base thymine, thus producing intermolecular 2 + 2 photoadducts (antigen within the cell), was also thought to be related to photosensitivity. Clinical manifestations vary from generalized eczema (20-30%), eczema of hands and face (24%), hand (36-44%), or facial eczema (11-28%). 65% of patients have vesicular hand eczema. Routine patch testing with sesquiterpene lactone mix, aimed testing with Compositae extracts screening mix, Compositae plants, and with their extracts, whereas the treatment of choice is a specific allergen-immunotherapy.

Patch testing can improve health-related quality of life (HRQOL). To study the impact on HRQOL of elapsed time after patch testing (1-10 years), and how the outcome of testing and patients' recall affects HRQOL. The Dermatology Life Quality Index (DLQI) questionnaire was sent to all patients (aged 18-65 years) who were patch tested for suspected contact allergy in 2009, 2005 and 2000 at the Department of Dermatology in Örebro. The response rate was 51% (n = 256). The DLQI score was significantly lower at 10 years after patch testing (mean DLQI = 5.5) than at 1 year (mean DLQI = 7.7). Work was the most impaired aspect. A binary logistic model showed that only time (10 years after testing) was associated with no effect, a light effect or a moderate effect (DLQI < 10) on HRQOL. No such association was seen for patients with negative or positive test results concerning full recall, partial recall or no recall of diagnosed allergens. Although there was an improvement in HRQOL over time, the work aspect remained a major problem. The improvement was not affected by the outcome of testing and patients' recall of test results. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Associations of childhood eczema severity: A US population based study

Little is known about predictors of eczema severity in the US population. We sought to determine the distribution and associations of childhood eczema severity in the US. We analyzed data from the 2007 National Survey of Children's Health, a prospective questionnaire-based study of a nationally representative sample of 91,642 children (0-17yr). The prevalence of childhood eczema was 12.97% (95% confidence interval [95% CI]=12.42–13.53); 67.0% (95% CI: 64.8–69.2) had mild, 26.0% (95% CI: 23.9–28.1) moderate and 7.0% (95% CI: 5.8–8.3) severe disease. There was significant statewide-variation of the distribution of eczema severity (Rao-Scott chi square, P=0.004), with highest rates of severe disease in Northeastern and Midwestern states. In univariate models, eczema severity was increased with older age, African-American and Hispanic race/ethnicity, lower household income, oldest child in the family, home with a single mother, lower paternal/maternal education level, maternal general health, maternal/paternal emotional health, dilapidated housing and garbage on the streets. In multivariate survey logistic regression models using stepwise and backward selection, moderate–severe eczema was associated with older age, lower household income and fair or poor maternal health, but inversely associated with birthplace outside the US. These data indicate that environmental and/or lifestyle factors play an important role in eczema severity. PMID:24819283

The prevalence of complementary and alternative medicine (CAM) use in US children with eczema is unknown. Furthermore, it is unknown whether CAM use in the United States is associated with higher eczema prevalence. We sought to determine the eczema prevalence in association with CAM usage. We analyzed data from the 2007 National Health Interview Survey that included a nationally representative sample of 9417 children ages 0 to 17 years. Overall, 46.9% (95% confidence interval, 45.6%-48.2%) of children in the United States used 1 or more CAM, of which 0.99% (0.28%-1.71%) used CAM specifically to treat their eczema, including herbal therapy (0.46%), vitamins (0.33%), Ayurveda (0.28%), naturopathy (0.24%), homeopathy (0.20%), and traditional healing (0.12%). Several CAMs used for other purposes were associated with increased eczema prevalence, including herbal therapy (survey logistic regression; adjusted odds ratio [95% confidence interval], 2.07 [1.40-3.06]), vitamins (1.45 [1.21-1.74]), homeopathic therapy (2.94 [1.43-6.00]), movement techniques (3.66 [1.62-8.30]), and diet (2.24 [1.10-4.58]), particularly vegan diet (2.53 [1.17-5.51]). In conclusion, multiple CAMs are commonly used for the treatment of eczema in US children. However, some CAMs may actually be harmful to the skin and be associated with higher eczema prevalence in the United States.

Whether ambient air pollution is associated with childhood atopic eczema is controversial. In this paper, we selected 3358 preschool children who had not altered residences since pregnancy from a cross-sectional study during 2011-2012 in Shanghai, China, and obtained parent-reported data regarding childhood atopic eczema using an improved ISAAC questionnaire. We recorded daily concentrations of SO 2 , NO 2 , and PM 10 throughout the child's lifetime (2006-2012), and calculated period-averaged concentrations for each district where the child lived to represent the child's exposure levels of these pollutants during different periods. In the multiple logistic regression analyses adjusted for potential confounders as well as for the other pollutants in the same periods, childhood atopic eczema was significantly associated with increments of NO 2 in the approximate interquartile range (20μg/m 3 ) during gestational period (adjusted OR, 95% CI for eczema lifetime-ever: 1.80, 1.29-2.49; for eczema in the year prior to the survey: 2.32, 1.57-3.43) and during the first year of life (2.00, 1.40-2.84; 2.16, 1.43-3.28). Exposure to elevated NO 2 in the first two years, three years and total lifetime, as well as exposure to mixtures containing NO 2 in each of these periods, were consistently associated with increased likelihood of childhood eczema. The highest odds ratios were found between exposure to a mixture of SO 2 and NO 2 during total lifetime (increment: 35μg/m 3 ) and childhood eczema (adjusted OR, 95% CI: 2.80, 1.75-4.48; 3.50, 1.98-6.19). No significant associations were found between childhood eczema and ambient SO 2 and PM 10 individually or in mixtures. This study indicates that gestational and lifetime exposures to ambient NO 2 are risk factors for atopic eczema in childhood. Exposure to ambient SO 2 and PM 10 may enhance the effect of NO 2 exposure on childhood eczema. Copyright © 2016 Elsevier B.V. All rights reserved.

Leave-on emollients form the mainstay of eczema treatment, but adherence is poor. We aimed to explore parents'/carers' views on effectiveness and acceptability of leave-on emollients for childhood eczema through secondary analysis of data from 2 qualitative data sets. Study 1 recruited through mail-out from 6 general practices in southern England. Study 2 recruited from a feasibility trial of an intervention to support eczema self-care in 31 practices in the same area. Study 1 included 28 interviews with carers of children aged ≤5 years with eczema. Study 2 included 26 interviews with carers of children aged ≤5 years with eczema. Interviews followed semistructured guides: study 1 explored carers' understandings around eczema treatments in order to develop a web-based self-care support intervention; study 2 explored carers' understandings of eczema and eczema treatments after using the intervention. Interviews were carried out face to face or by telephone, audio-recorded and transcribed. Secondary analysis of data from both studies focused on views and experiences of emollient use. Data were analysed using an inductive thematic approach facilitated by NVivo V.10 software. In study 1, most participants felt emollients improved eczema but held mixed views about long-term use to prevent flare-ups. In study 2, where carers had used the web-based intervention, all participants held positive views about long-term emollient use. In both studies, participants expressed a range of preferences about emollient 'thickness'; some felt that 'thick' emollients (ointments) were most effective, while others found these difficult to use. Carers described a process of 'trial and error', trying emollients suggested by professionals, friends and family, or bought over-the-counter. Carers expressed a need for understanding differences between products and their effective use. Providing a rationale for long-term emollient use and choice of emollients could help improve adherence and help families gain more rapid control of eczema.

Cyclic adenosine monophosphate phosphodiesterases (PDEs) regulate pro-inflammatory cytokine production. One isoform, PDE4, is overactive in chronic relapsing inflammatory skin diseases: psoriasis and eczema/atopic dermatitis, and in several cancers. East Indian sandalwood oil (EISO) has significant anti-inflammatory properties. Here, we report that 75% of pediatric eczema/atopic dermatitis patients treated with topical EISO formulations achieved a >50% reduction in their Eczema Area and Severity Index score. EISO treatment of a psoriasis model reduced PDE4 expression and reversed histopathology. EISO directly inhibited PDE enzymatic activity in vitro . In lipopolysaccharide-stimulated human dermal fibroblast, BEAS-2B, A549, and THP-1 cells, EISO suppressed total cellular PDE activity, PDE4, and 7 transcript levels, nuclear factor kappa B (NF-κB) activation, and pro-inflammatory cytokines/chemokine production. These results suggest that EISO anti-inflammatory activity is mediated through suppressing PDE activity, thus facilitating cAMP-regulated inhibition of NF-κB and indicate EISO as an attractive natural therapeutic for chronic and acute inflammatory disorders.

Contradictory results exist regarding the importance of early-life exposure to phthalates for development of childhood eczema. We evaluated the association between maternal urinary concentrations of phthalate metabolites between the 24th and 28th week of gestation and occurrence of eczema in their sons up to 5 y of age, according to allergic sensitization as assessed by total immunoglobulin E (IgE) in a subsample of individuals. Data on health outcomes and background factors were collected using five standardized annual questionnaires completed by parents at the children's ages of 1-5 y, and their associations with phthalate metabolite urinary concentrations were assessed in 604 mother-son pairs with adjusted multiple logistic regression and Cox's survival model. Several eczema phenotypes were considered. Atopic status was assessed at 5 y of age in 293 boys through total IgE assessment. At 5 y of age, the prevalence of ever eczema was 30.4%. Metabolites of di-isobutyl phthalate (DiBP) and di-isononyl phthalate (DiNP) were positively associated with early-onset (0-24 mo of age) eczema (15.7%) and late-onset (24-60 mo of age) eczema (14.7%). Applying the Cox's model showed a significant association of occurrence of eczema in the first 5 y of life with DiBP and DiNP metabolites. Among IgE-sensitized boys, metabolites of di- n -butyl phthalate (DBP) and DiBP were significantly associated with ever eczema {hazard ratio (HR)=1.67 [95% confidence interval (CI): 1.10, 2.54], p =0.01 and HR=1.87 (95% CI: 1.01, 3.48), p =0.04, respectively}. Occurrence of eczema in early childhood may be influenced by prenatal exposure to certain phthalates in boys. Further investigations are needed to confirm this observation. https://doi.org/10.1289/EHP1829.

Objective Exposure to endotoxin in early life has been proposed as a factor that may protect against the development of allergic diseases such as eczema. The objective of this study was to examine the relation between endotoxin exposure in early life and eczema in the first year of life in children with parental history of asthma or allergies. Methods This study used a prospective birth cohort study of 498 children who had a history of allergy or asthma in at least 1 parent and lived in metropolitan Boston. A subset of 401 living rooms had house dust samples adequate for analysis of endotoxin. Results In multivariate analyses adjusting for gender, income, and season of birth, endotoxin levels in the living room at 2 to 3 months of age was inversely associated with physician- or nurse-diagnosed eczema in the first year of life (odds ratio [OR] for each quartile increment: 0.76; 95% confidence interval [CI]: 0.61–0.96). Exposure to a dog in the home at age 2 to 3 months was also inversely associated with eczema in the first year of life, but the CI widened when endotoxin was included in the multivariate model (OR: 0.54; 95% CI: 0.27–1.09). Other variables associated with eczema in the first year of life included paternal history of eczema (OR: 1.91; 95% CI: 1.03–3.55) and maternal specific immunoglobulin E positivity to ≥1 allergen (OR: 1.61; 95% CI: 1.01–2.56). Conclusions Among children with parental history of asthma or allergies, exposure to high levels of endotoxin in early life may be protective against eczema in the first year of life. In these children, paternal history of eczema and maternal sensitization to at least 1 allergen are associated with an increased risk of eczema in the first year of life. PMID:15231902

Atopic dermatitis is a chronic skin disorder with high prevalence, especially in the Nordic countries. Effective maintenance therapy during symptom-free episodes may prolong the time to eczema relapse according to a previously published clinical trial. The present study evaluates the cost-effectiveness of a barrier-strengthening moisturizer containing 5% urea, compared with a moisturizer with no active ingredients during eczema-free periods. A health economic microsimulation model, based on efficacy data from the randomized clinical trial, analysed the cost-effectiveness of the barrier-strengthening treatment in Finland, Norway and Sweden. The barrier-strengthening moisturizer was cost-saving compared with the moisturizer with no active ingredients in all 3 countries. The result was confirmed in all but one sensitivity analysis. In conclusion, the barrier-strengthening moisturizer is cost-effective as maintenance therapy for patients with atopic dermatitis compared with a moisturizer with no active ingredients.

Atopic dermatitis (AD) is a disease characterized by relapsing eczema with pruritus as a primary lesion. Most patients have an atopic predisposition. The definitive diagnosis of AD requires the presence of all three features: (i) pruritus; (ii) typical morphology and distribution of the eczema; and (iii) chronic and chronically relapsing course. The current strategies to treat AD in Japan from the perspective of evidence-based medicine consist of three primary measures: (i) the use of topical corticosteroids and tacrolimus ointment as the main treatment for the inflammation; (ii) topical application of emollients to treat the cutaneous barrier dysfunction; and (iii) avoidance of apparent exacerbating factors, psychological counseling and advice about daily life. The guidelines present recommendations to review clinical research articles, evaluate the balance between the advantages and disadvantages of medical activities, and optimize medical activity-related patient outcomes with respect to several important points requiring decision-making in clinical practice. © 2016 Japanese Dermatological Association.

This study investigated the extent to which single mothers of children with atopic eczema experience disease-related stress. A total of 96 mothers were divided into 4 groups: mothers living with a partner, who had or did not have a child with atopic eczema, and single mothers, who had or did not have a child with atopic eczema. The following questionnaires were used to assess psychological burden: Short Stress Questionnaire (Kurzer Fragebogen zur Erfassung von Belastung; KFB), Satisfaction with Life Questionnaire (Fragebogen zur Lebenszufriedenheit; FLZ), General Depression Scale (Allgemeine Depressions-Skala; ADS), and the Questionnaire for Parents of Children with Atopic Eczema (Fragebogen für Eltern von Neurodermitis kranken Kindern; FEN). Single mothers had higher levels of helplessness and aggression due to their child's scratching behaviour than did mothers living with a partner and a child with atopic eczema. Single mothers of children with atopic eczema had the highest scores regarding experienced stress in the family and the lowest scores concerning general life satisfaction. Special care should be provided for single mothers with higher stress, in order to teach them how to deal with the scratching behaviour of their children.

To diagnose atopic dermatitis (AD), an appearance of eczema examined by experienced dermatologists is required. Therefore, biomarkers to diagnose AD or to reflect the severity of AD would be of a great use for non-specialists in the clinic or hospitals. We can apply such a biomarker for realization of personalized medicine for AD in the future. Interleukin-4 (IL-4) and IL-13 have been known to play important roles in the pathogenesis of allergic diseases including AD. In addition to these, we previously identified SCCA1, SCCA2, and periostin as IL-4/IL-13-inducible genes. We recently established ELISA systems to measure serum levels of SCCA1, SCCA2, and periostin and evaluated their usefulness in the treatment of AD patients. Serum SCCA1 and SCCA2 are up-regulated in AD patients and can distinguish AD patients from non-atopic controls, and their serum levels reflect eczema grades. Periostin concentration is also elevated in the serum of AD patients. These results demonstrate that SCCA1, SCCA2, and periostin might be promising biomarkers for personalized medicine in allergic diseases including AD.

Precise knowledge of the prevalence and spectrum of skin diseases in a population allows for effective planning for provision of dermatology services and distribution of resources. There are no published data on the epidemiology of skin disorders in Durban, KwaZulu-Natal. We investigated the prevalence of skin diseases in black African patients attending a predominantly black private healthcare facility and profiled the patients. Clinical charts of all black African patients seen between January 2003 and December 2010 in a private practice in Durban were reviewed. The diseases seen were described and the prevalence calculated. A total of 6664 patient charts were reviewed. The five most common conditions were acne, eczemas, dyschromias, infections, and hair disorders. These data agree with reports from other parts of the world. Selection bias was presented by a single private practice, thus data may not be fully representative of our population. Acne, eczemas, dyschromias, infections, and hair disorders are, in that order, the five most common disorders encountered. © 2014 The International Society of Dermatology.

There are no known reports of the frequency of skin diseases endemic to rural Yucatan, Mexico. The aim of this study was to report the prevalence of dermatologic conditions in rural villages in that region. We conducted a retrospective descriptive study of all cases of skin disease diagnosed by a team of American board-certified dermatologists during consultations in January 2009, August 2009, and June 2010, in the state of Yucatan, Mexico. Traveling clinics were held in eight different rural locations. Age, sex, and diagnosis, according to history and physical examination, were recorded for each patient. A total of 1071 cases of skin disease were seen in 858 patients. The frequency of parasitic, viral, and fungal infections was 34.5%. Dermatitis and eczema (24.6%) were the next most prevalent conditions, followed by disorders of skin appendages (12.2%), photosensitivity disorders (5.4%), papulosquamous disorders (3.2%), urticaria and erythema (1.5%), bacterial infections of the skin and subcutaneous tissue (1.2%), and neoplastic disorders (2.1%). The most frequently seen single diagnoses were viral warts (12.2%), scabies (8.7%), acne (7.4%), dermatophytosis (6.8%), contact dermatitis (3.5%), and nummular eczema (3.5%). Infectious diseases, acne, and eczemas are the most common skin disorders seen in dermatology clinics in rural Yucatan, Mexico. Our findings may be useful in the development of public health initiatives targeting rural communities in this region. © 2012 The International Society of Dermatology.

Abstract Objectives To determine the clinical effectiveness and cost effectiveness of including emollient bath additives in the management of eczema in children. Design Pragmatic randomised open label superiority trial with two parallel groups. Setting 96 general practices in Wales and western and southern England. Participants 483 children aged 1 to 11 years, fulfilling UK diagnostic criteria for atopic dermatitis. Children with very mild eczema and children who bathed less than once weekly were excluded. Interventions Participants in the intervention group were prescribed emollient bath additives by their usual clinical team to be used regularly for 12 months. The control group were asked to use no bath additives for 12 months. Both groups continued with standard eczema management, including leave-on emollients, and caregivers were given standardised advice on how to wash participants. Main outcome measures The primary outcome was eczema control measured by the patient oriented eczema measure (POEM, scores 0-7 mild, 8-16 moderate, 17-28 severe) weekly for 16 weeks. Secondary outcomes were eczema severity over one year (monthly POEM score from baseline to 52 weeks), number of eczema exacerbations resulting in primary healthcare consultation, disease specific quality of life (dermatitis family impact), generic quality of life (child health utility-9D), utilisation of resources, and type and quantity of topical corticosteroid or topical calcineurin inhibitors prescribed. Results 483 children were randomised and one child was withdrawn, leaving 482 children in the trial: 51% were girls (244/482), 84% were of white ethnicity (447/470), and the mean age was 5 years. 96% (461/482) of participants completed at least one post-baseline POEM, so were included in the analysis, and 77% (370/482) completed questionnaires for more than 80% of the time points for the primary outcome (12/16 weekly questionnaires to 16 weeks). The mean baseline POEM score was 9.5 (SD 5.7) in the bath additives group and 10.1 (SD 5.8) in the no bath additives group. The mean POEM score over the 16 week period was 7.5 (SD. 6.0) in the bath additives group and 8.4 (SD 6.0) in the no bath additives group. No statistically significant difference was found in weekly POEM scores between groups over 16 weeks. After controlling for baseline severity and confounders (ethnicity, topical corticosteroid use, soap substitute use) and allowing for clustering of participants within centres and responses within participants over time, POEM scores in the no bath additives group were 0.41 points higher than in the bath additives group (95% confidence interval −0.27 to 1.10), below the published minimal clinically important difference for POEM of 3 points. The groups did not differ in secondary outcomes, economic outcomes, or adverse effects. Conclusions This trial found no evidence of clinical benefit from including emollient bath additives in the standard management of eczema in children. Further research is needed into optimal regimens for leave-on emollient and soap substitutes. Trial registration Current Controlled Trials ISRCTN84102309. PMID:29724749

Objective: To estimate the prevalence of eczema in early childhood and effect of infant feeding practice on eczema by different regions of China with diverse climate and dietary patterns. Method: A questionnaire survey was conducted from June 2012 to October 2012 in Shanghai, Hohhot, and Fuzhou. The parent or guardian of the children aged between 2.5 to 3.5 years attending routine health visit in the chosen communities were invited to complete a modified questionnaire of the International Study of Asthma and Allergy in Childhood (ISAAC). Logistic regression model was used to analyze of the family history of allergy, duration of breastfeeding, timing of introduction of complementary foods and other potential confounders. Result: A total of 2 242 children were interviewed, 750 from Shanghai, 716 from Hohhot, and 776 from Fuzhou. The prevalence of eczema in early childhood was significantly different among Shanghai (16.9%, 95% CI 16.87-16.93), Hohhot (34.5%, 95% CI 34.46-34.54)and Fuzhou (44.3%, 95% CI 44.26-44.34). The difference was statistically significant between 3 groups (χ 2 =72.05, P <0.05). Introducing complementary food after the age of 6 months was associated with a decreased risk for eczema when compared to introduction between 4 to 6 months(odds ratio (OR) 0.58, 95% CI 0.41-0.81) in Fuzhou, while there was no significant association between timing of introduction of complementary foods and eczema in Shanghai and Hohhot. Conclusion: The prevalence of eczema during early childhood is various among three cities. The relationship between timing of introduction of complementary foods and eczema in Fuzhou is different from that in Shanghai and Hohhot. The role of climate and dietary patterns on prevalence of eczema needs further studies.

Background Small proline rich protein 2B (SPRR2B) is a skin and lung epithelial protein associated with allergic inflammation in mice that has not been evaluated in human atopic diseases. Objective To determine whether single-nucleotide polymorphisms (SNPs) in SPRR2B are associated with childhood eczema and with the phenotype of childhood eczema combined with asthma. Methods Genotyping for SPRR2B and filaggrin (FLG) was performed in 2 independent populations: the Cincinnati Childhood Allergy & Air Pollution Study (CCAAPS; N = 762; birth-age, 4 years) and the Greater Cincinnati Pediatric Clinical Repository (GCPCR;N = 1152; ages 5–10 years). Eczema and eczema plus asthma were clinical outcomes based on parental report and clinician’s diagnosis. Genetic analyses were restricted to whites and adjusted for sex in both cohorts and adjusted for environmental covariates in CCAAPS. Results Variants in SPRR2B were not significantly associated with eczema in either cohort after Bonferroni adjustment. Children from both cohorts with the CC genotype of the SPRR2B rs6693927 SNP were at 4 times the risk for eczema plus asthma (adjusted odds ratio, 4.1; 95% confidence interval, 1.5– 10.9; P = .005 in CCAAPS; and adjusted odds ratio, 4.0; 95% confidence interval, 1.8 –9.1; P <.001 in the GCPCR), however. SNPs in SPRR2B were not in strong linkage disequilibrium with the R501X and del2282 FLG mutations, and these findings were independent of FLG. Conclusions An SNP in SPRR2B was predictive of asthma among white children with eczema from 2 independent populations. SPRR2B polymorphisms may serve as important predictive markers for the combined eczema plus asthma phenotype. PMID:22374195

The prevalence of childhood eczema varies considerably between ethnic groups. However, data from longitudinal studies remain scarce. We examined the associations of ethnic origin with the development of eczema from birth until the age of 4 years, and whether known environmental and genetic risk factors explain these associations. This study was performed in a multiethnic population-based prospective cohort among 5,082 children. Ethnic origin was based on the parents' country of birth. Data on physician-diagnosed eczema were obtained by annual questionnaires. Information on environmental risk factors was mostly obtained by questionnaires. Filaggrin (FLG) mutations (2282del4, R2447X, R501X, and S3247X) were genotyped for 3,096 children. We used generalized estimating equation models to examine the associations of ethnic origin with the longitudinal odds of eczema at 6 months and 1, 2, 3, and 4 years of age overall and independently. Compared with Dutch children, Cape Verdean, Dutch Antillean, Surinamese-Creole, and Surinamese-Hindustani children had overall increased risks of eczema (OR (95%-CI): 1.53 (1.15, 2.03), 1.60 (1.21, 2.12), 1.95 (1.56, 2.44), and 2.06 (1.65, 2.57), respectively). Effect estimates for the associations of Cape Verdean and Dutch Antillean origin with eczema became non-significant after adjustment for genetic risk factors or both environmental and genetic risk factors, respectively. Surinamese-Creole and Surinamese-Hindustani children remained to have increased risks of eczema. Cape Verdean, Dutch Antillean, Surinamese-Creole, and Surinamese-Hindustani children had increased risks of eczema in the first 4 years of life. Environmental and genetic risk factors partly weakened these associations. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Background Loss-of-function variants within the filaggrin gene (FLG) are associated with a dysfunctional skin barrier that contributes to the development of eczema. Epigenetic modifications, such as DNA methylation, are genetic regulatory mechanisms that modulate gene expression without changing the DAN sequence. Objectives To investigate whether genetic variants and adjacent differential DNA methylation within the FLG gene synergistically act on the development of eczema. Methods A subsample (n = 245, only females aged 18 years) of the Isle of Wight birth cohort participants (n = 1,456) had available information for FLG variants R501X, 2282del4, and S3247X and DNA methylation levels for 10 CpG sites within the FLG gene. Log-binomial regression was used to estimate the risk ratios (RRs) of eczema associated with FLG variants at different methylation levels. Results The period prevalence of eczema was 15.2% at age 18 years and 9.0% of participants were carriers (heterozygous) of FLG variants. Of the 10 CpG sites spanning the genomic region of FLG, methylation levels of CpG site ‘cg07548383’ showed a significant interaction with FLG sequence variants on the risk for eczema. At 86% methylation level, filaggrin haploinsufficient individuals had 5.48-fold increased risk of eczema when compared to those with wild type FLG genotype (p-value = 0.0008). Conclusions Our novel results indicated that the association between FLG loss-of-function variants and eczema is modulated by DNA methylation. Simultaneously assessing the joint effect of genetic and epigenetic factors within the FLG gene further highlights the importance of this genomic region for eczema manifestation. PMID:23003573

Background Perinatal maternal stress and low mood have been linked to offspring atopic eczema. Objectives To examine the relation of maternal stress/mood with atopic eczema in the offspring, focusing particularly on stress/psychological distress preconception. Methods At recruitment in the UK Southampton Women’s Survey, preconception maternal reports of perceived stress in daily living and the effect of stress on health were recorded; in a sub-sample psychological distress was assessed (12-item General Health Questionnaire). Infants were followed up at ages 6 (n=2956) and 12 (n=2872) months and atopic eczema ascertained (based on UK Working Party Criteria for the Definition of Atopic Dermatitis). At 6 months postpartum, mothers were asked if they had experienced symptoms of low mood since childbirth and completed the Edinburgh Post-natal Depression Scale. Results Preconception perceived stress affecting health (OR 1.21 (95%CI 1.08-1.35), p=0.001) and stress in daily living (OR 1.16 (1.03-1.30), p=0.014) were associated with an increased risk of offspring atopic eczema at age 12 months but not at 6 months, robust to adjustment for potentially confounding variables. Findings were similar for maternal psychological distress preconception. Low maternal mood between delivery and 6 months postpartum was associated with an increased risk of infantile atopic eczema at age 12 months, but no significant association between postnatal mood and atopic eczema was seen after taking account of preconception stress. Conclusion & Clinical Relevance Our data provide novel evidence linking maternal stress at preconception to atopic eczema risk, supporting a developmental contribution to the aetiology of atopic eczema and pointing to potentially modifiable influences.

Hydroxyisohexyl-3-cyclohexene carboxaldehyde (HICC) known as Lyral is a frequent allergen. It is used in more than 50% of marketed deodorants. The aim of the present study was to determine elicitation thresholds for HICC under simulated conditions of deodorant use. 15 patients with previously diagnosed contact allergy to HICC were patch tested with 5 solutions of HICC-scented and HICC-unscented deodorants. Patients and 10 healthy controls performed a use test in the axillae using deodorants scented with HICC in increasing concentrations and unscented deodorants as control. The concentration of HICC was increased every second week (200, 600, and 1800 p.p.m.) until either a reaction developed or for 6 weeks. 14 patients completed the study, and all developed unilateral eczema from the HICC-containing deodorant, while controls were all negative (P= 0.004). In 9/14 patients, a positive use test developed during the first 2 weeks to the deodorant containing 200 p.p.m. HICC. Positive correlations were found between the day of positive use and patch test threshold concentration of the HICC solutions (r= 0.71, P= 0.01) as well as the patch test thresholds of the HICC-scented deodorants (r= 0.74, P= 0.007). In conclusion, HICC elicits allergic contact dermatitis in a high proportion of sensitized individuals at common usage concentrations in deodorants.

First studies have shown that juvenile psoriasis is associated with an increased prevalence of comorbidity. We carried out a data analysis to characterise the profiles of comorbidity in children with psoriasis and atopic eczema. Prevalence data were derived from the database of a German statutory health insurance company according to ICD-10 codes L40 (psoriasis) and L20 (atopic eczema) of children up to 18 years insured in 2009. Data sets included 1.64 million persons and 293,181 children. 1,313 children = 0.45% (0.42-0.47) had a diagnosis of psoriasis and 30,354 = 10.35% (10.24-10.47) had a diagnosis of atopic eczema. Obesity, hyperlipidaemia, arterial hypertension and diabetes were more often diagnosed in children with psoriasis in comparison to all children without psoriasis and to those with atopic eczema. Children with psoriasis and atopic eczema show different and specific patterns of comorbidity which should be detected early and treated adequately. © 2015 S. Karger AG, Basel.

There are reports that the maternal diet during pregnancy may affect development of babies' eczema. We sought to investigate the association between the maternal diet during pregnancy and the risk of eczema in infancy in Japan. A birth cohort was set up at 2 hospitals in Chiba city. Dietary habits concerning fish, butter, margarine, yogurt and natto during pregnancy was obtained from mothers just after delivery. The intake frequencies of these foods were classified into four groups: 1) daily, 2) 2-3 times a week, 3) once a week and 4) once a month or less. Diagnosis of eczema at 6 months of age was made by the presence of an itchy rash that persisted more than two months. Valid data on 650 mother-baby pairs were obtained. No relationship between frequencies of the maternal intake of fish, margarine and yogurt during pregnancy and the onset rate of the babies' eczema were observed. For butter consumption, the incidence of babies' eczema was significantly higher in the group with daily intake than in those with an intake 2-3 times a week or less (p = 0.044). For natto, incidence of babies' eczema was significantly lower in the group with everyday intake than those eating it 2-3 times a week or less (p = 0.020). High frequency intake of natto during pregnancy possibly reduces the incidence of eczema in children at 6 months of age.

Eczema in early childhood is strongly associated with the development of asthma and rhinitis in a prospective cohort

PubMed Central

2012-01-01

Background This study aimed to estimate the association between eczema in early childhood and the onset of asthma and rhinitis later in life in children. Methods A total of 3,124 children aged 1–2 years were included in the Dampness in Building and Health (DBH) study in the year 2000, and followed up 5 years later by a parental questionnaire based on an International Study of Asthma and Allergies in Childhood protocol. The association between eczema in early childhood and the incidence of asthma and rhinitis later in life was estimated by univariable and multivariable logistic regression modelling. Results The prevalence of eczema in children aged 1–2 years was 17.6% at baseline. Children with eczema had a 3-fold increased odds of developing asthma (adjusted odds ratio [aOR], 3.07; 95% confidence interval (CI) 1.79–5.27), and a nearly 3-fold increased odds of developing rhinitis (aOR, 2.63; 1.85–3.73) at follow-up compared with children without eczema, adjusted for age, sex, parental allergic disease, parental smoking, length of breastfeeding, site of living, polyvinylchloride flooring material, and concomitant allergic disease. When eczema was divided into subgroups, moderate to severe eczema (aOR, 3.56; 1.62–7.83 and aOR, 3.87; 2.37–6.33, respectively), early onset of eczema (aOR, 3.44; 1.94–6.09 and aOR, 4.05; 2.82–5.81; respectively), and persistence of eczema (aOR, 5.16; 2.62–10.18 and aOR, 4.00; 2.53–6.22, respectively) further increased the odds of developing asthma and rhinitis. Further independent risk factors increasing the odds of developing asthma were a parental history of allergic disease (aOR, 1.83; 1.29–2.60) and a period of breast feeding shorter than 6 months (aOR, 1.57; 1.03–2.39). The incidence of rhinitis was increased for parental history of allergic disease (aOR, 2.00; 1.59–2.51) and polyvinylchloride flooring (aOR, 1.60; 1.02–2.51). Conclusion Eczema in infancy is associated with development of asthma and rhinitis during the following 5-year period, and eczema is one of the strongest risk factors. Early identification is valuable for prediction of the atopic march. PMID:22839963

Specific allergen immunotherapy (SIT) is an effective allergy treatment, but it is unclear whether SIT is effective for atopic eczema (AE). We undertook a systematic review to assess SIT efficacy and safety for treating AE. We searched databases, ongoing clinical trials registers, and conference proceedings up to July 2015. Randomized controlled trials (RCTs) of SIT using standardized allergen extracts, compared with placebo/control, for treating AE in patients with allergic sensitization were eligible. We identified 12 eligible trials with 733 participants. Interventions included subcutaneous (six trials), sublingual (four trials), oral or intradermal SIT in children/adults allergic to house dust mite (10 trials), grass pollen or other inhalants. Risk of bias was moderate, with high loss to follow-up and nonblinding as the main concerns. For our primary outcomes, three studies (208 participants) reported no significant difference - patient-reported global disease severity improvement RR 0.75 (95% CI 0.45, 1.26); and eczema symptoms mean difference -0.74 on a 20-point scale (95% CI -1.98, 0.50). Two studies (85 participants) reported a significant difference - SIT improved global disease severity RR 2.85 (95% CI 1.02, 7.96); and itch mean difference -4.20 on a 10-point scale (95% CI -3.69, -4.71). Meta-analysis was limited due to extreme statistical heterogeneity. For some secondary outcomes, meta-analyses showed benefits for SIT, for example investigator-rated improvement in eczema severity RR 1.48 (95% CI 1.16, 1.88; six trials, 262 participants). We found no evidence of adverse effects. The overall quality of evidence was low. We found no consistent evidence that SIT is effective for treating AE, but due to the low quality of evidence further research is needed to establish whether SIT has a role in AE treatment. © 2016 John Wiley & Sons A/S.

Children with severe, persistent atopic eczema (AE) have limited treatment options, often requiring systemic immunosuppression. To evaluate the effect of the temperature-controlled laminar airflow (TLA) treatment in children/adolescents with severe AE. We recruited 15 children aged 2-16 years with long-standing, severe AE and sensitization to ≥1 perennial inhalant allergen. Run-in period of 6-10 weeks (3 visits) was followed by 12-month treatment with overnight TLA (Airsonett ® , Sweden). The primary outcome was eczema severity (SCORAD-Index and Investigator Global Assessment-IGA). Secondary outcomes included child/family dermatology quality of life and family impact questionnaires (CDQLI, FDQLI, DFI), patient-oriented eczema measure (POEM), medication requirements and healthcare contacts. The study is registered as ISRCTN65865773. There was a significant reduction in AE severity ascertained by SCORAD and IGA during the 12-month intervention period (P < .001). SCORAD was reduced from a median of 34.9 [interquartile range 28.75-45.15] at Baseline to 17.2 [12.95-32.3] at the final visit, and IGA improved significantly from 4 [3-4] to 2 [1-3]. We observed a significant improvement in FDQLI (16.0 [12.25-19.0] to 12 [8-18], P = .023) and DFI (P = .011), but not CDQLI or POEM. Compared to 6-month period prior to enrolment, there was a significant reduction at six months after the start of the intervention in potent topical corticosteroids (P = .033). The exploratory cluster analysis revealed two strongly divergent patterns of response, with 9 patients classified as responders, and 6 as non-responders. Addition of TLA device to standard pharmacological treatment may be an effective add-on to the management of difficult-to-control AE. © 2018 John Wiley & Sons Ltd.

Evidence of immunomodulatory therapies to guide clinical management for atopic eczema (AE) is scarce, despite frequent and often off-label use. Patient registries provide valuable evidence for the effects of treatments under real world conditions which can inform treatment guidelines, give the opportunity for health economic evaluation and the evaluation of quality of care, as well as pharmacogenetic and -dynamic research which cannot be adequately addressed in clinical trials. The TREatment of ATopic eczema (TREAT) Registry Taskforce aims to seek international consensus on a core set of domains and items ('what to measure') for AE research registries, using a Delphi approach. Participants from six stakeholder groups were included: doctors, nurses, non-clinical researchers, patients, industry and regulatory body representatives. The eDelphi comprised 3 sequential online rounds, requesting participants to rate the importance of each proposed domain item. Participants could add domain items to the proposed list in round 1. A final consensus meeting was held to ratify the core set. 479 participants from 36 countries accessed the eDelphi platform, of whom 86%, 79% and 74% completed rounds 1, 2, and 3 respectively. At the face-to-face consensus meeting attended by 42 participants the final core set was established containing 19 domains with 69 domain items (49 baseline and 20 follow-up items). This core set of domains and items to be captured by national AE systemic therapy registries will standardise data collection and thereby allow direct comparability across registries and facilitate data pooling between countries. Ultimately, it will provide greater insight into the effectiveness, safety and cost-effectiveness of photo- and systemic immunomodulatory therapies. This article is protected by copyright.

A modest number of prospective studies of the composition of the intestinal microbiota and eczema in early life have yielded conflicting results. To examine the relationship between the bacterial diversity of the gut and the development of eczema in early life by methods other than stool culture. Fecal samples were collected from 21 infants at 1 and 4 months of life. Nine infants were diagnosed with eczema by the age of 6 months (cases) and 12 infants were not (controls). After conducting denaturating gradient gel electrophoresis (DGGE) of stool samples, we compared the microbial diversity of cases and controls using the number of electrophoretic bands and the Shannon index of diversity (H') as indicators. Control subjects had significantly greater fecal microbial diversity than children with eczema at ages 1 (mean H' for controls = 0.75 vs. 0.53 for cases, P = 0.01) and 4 months (mean H' for controls = 0.92 vs. 0.59 for cases, P = 0.02). The increase in diversity from 1 to 4 months of age was significant in controls (P = 0.04) but not in children who developed eczema by 6 months of age (P = 0.32). Our findings suggest that reduced microbial diversity is associated with the development of eczema in early life.

Successful sleep onset and maintenance is associated with a reduction in core temperature, facilitated by heat loss at the distal periphery. Problems with initiating and maintaining sleep in children with eczema may relate to impaired thermoregulatory mechanisms, which also contribute to itching and scratching. Our hypothesis was that nocturnal distal skin temperature in eczematous children would be lower than controls, and would also be related to poor sleep quality. We compared overnight polysomnography and distal (finger) and proximal (clavicle) skin temperature in 18 children with eczema and 15 controls (6-16 years). Children with eczema had longer periods of nocturnal wakefulness (mean [SD] = 88.8 [25.8] vs. 44.3 [35.6] min) and lower distal temperatures (34.1 [0.6] °C vs. 34.7 [0.4] °C) than controls, whereas proximal temperature and the distal-proximal gradient were not significantly different. In children with eczema, a higher distal temperature was associated with indicators of poor sleep quality, whereas lower distal temperature was related to more scratching events during sleep. In conclusion, our findings indicate complex interrelationships among eczema, thermoregulation and sleep, and further, that deficits in thermoregulatory mechanisms may contribute to sleep disturbances in children with eczema.

No high level evidence to support the use of oral H1 antihistamines as monotherapy for eczema: a summary of a Cochrane systematic review

PubMed Central

2014-01-01

Background The most important symptom as well as one of the major diagnostic criteria for eczema is itch. Although oral antihistamines continue to be prescribed for people with eczema, it is unclear if they are effective and safe in relieving itch and skin lesions. We sought to evaluate the available evidence on effectiveness of oral antihistamines (H1 antagonists) as monotherapy in children and adults with eczema. Methods Searches included 10 databases and trial registers as well as conference proceedings (January 2014). Randomised controlled trials that assessed the effects of oral H1 antihistamines as monotherapy in children and adults with eczema were included. Results Our searches retrieved 757 references, but no randomised controlled trial met our inclusion criteria. Most studies allowed concomitant treatments, making the assessment of the individual effects of oral H1 antihistamines impossible. Conclusions There is currently no high-level evidence to support or refute the efficacy or safety of oral H1 antihistamines used as monotherapy for eczema. A further review of studies that assesses the effects of oral H1 antihistamines as ‘add-on’ therapy together with concomitant treatments is warranted to determine the beneficial effects of this group of medications in the treatment of eczema.

Evidence linking prenatal exposure to outdoor air pollution with eczema in early childhood is scare, and the role of components of air pollution and exposure timing remains unclear. We investigated the association between exposure to air pollution during preconceptional and perinatal period and the risk of eczema in preschool children. We conducted a prospective cohort study of 2598 children aged 3-6 years in Changsha, China. The prevalence of eczema was assessed by a standardized health questionnaire administered by the parents. Individual exposures to nitrogen dioxide (NO 2 ), sulfur dioxide (SO 2 ) and particulate matter with an aerodynamic diameter≤10μm (PM 10 ) during the 4th-6th and 1st-3rd month before pregnancy, entire pregnancy, and three trimesters were estimated by an inverse distance weighted (IDW) method based on concentrations measured at monitoring stations. Association between childhood eczema and exposure to air pollution was examined by logistic regression models in terms of odds ratio (OR) and 95% confidence interval (CI) for an interquartile range (IQR) increase in exposure. Life-time prevalence of eczema in preschool children in Changsha was 28.6%. Childhood eczema was associated with traffic-related air pollutant NO 2 during 3 months before pregnancy and entire pregnancy with adjusted ORs=1.19 (95% CI: 1.04-1.37) and 1.21 (95% CI: 1.03-1.42) respectively. The highest risk of eczema was observed for the 1st trimester exposure to NO 2 [OR=1.26 (95% CI: 1.09-1.46)]. However, no association was detected for SO 2 and PM 10 exposure during any window. High-level exposure to NO 2 during the whole time period significantly increased the effect of NO 2 in all windows on eczema risk as compared with low-level exposure. Sensitivity analysis indicated that the association between both preconceptional and perinatal exposure to NO 2 and childhood eczema was consistent and robust, and this association was modified by some personal, parental hereditary and indoor environmental factors. Our findings support the hypothesis that early childhood eczema is associated with exposure to traffic-related air pollutant during both preconceptional and perinatal period, especially at a high level of exposure.

Dermatological examination and patch tests with 34 rubber components were carried out in 114 tire manufacturers, 78 women and 36 men aged 29 years on average, with a mean duration of work in the plant 7 years. For correct interpretation of the obtained results patch tests with the same components were done in two control groups that is in 120 healthy subjects and 120 patients with contact dermatitis. Patch tests with proper concentrations of the studied components were evaluated after 48, 72 and 96 hours. Positive patch tests were found most frequently with antioxidants--16.6% (including IPPD--8.6%), followed by vulcanization accelerators--10.6%, and other rubber components--11.4% in all. During about 3 years of follow-up in 4 manufacturers contact allergic eczema was noted and polyvalent hypersensitivity to antioxidants and vulcanization accelerators without clinical manifestations of this hypersensitivity was diagnosed in 3 other subjects.

Background Many research studies have been published on atopic eczema and these are often summarised in systematic reviews (SRs). Identifying SRs can be time-consuming for health professionals, and researchers. In order to facilitate the identification of important research, we have compiled an on-line resource that includes all relevant eczema reviews published since 2000. Methods SRs were searched for in MEDLINE (Ovid), EMBASE (Ovid), PubMed, the Cochrane Database of Systematic Reviews, DARE and NHS Evidence. Selected SRs were assessed against the pre-defined eligibility criteria and relevant articles were grouped by treatment category for the included interventions. All identified systematic reviews are included in the Global Resource of EczemA Trials (GREAT) database (www.greatdatabase.org.uk) and key clinical messages are summarised here. Results A total of 128 SRs reviews were identified, including three clinical guidelines. Of these, 46 (36%) were found in the Cochrane Library. No single database contained all of the SRs found. The number of SRs published per year has increased substantially over the last thirteen years, and reviews were published in a variety of clinical journals. Of the 128 SRs, 1 (1%) was on mechanism, 37 (29%) were on epidemiology, 40 (31%) were on eczema prevention, 29 (23%) were on topical treatments, 31 (24%) were on systemic treatments, and 24 (19%) were on other treatments. All SRs included searches of MEDLINE in their search methods. One hundred six SRs (83%) searched more than one electronic database. There were no language restrictions reported in the search methods of 52 of the SRs (41%). Conclusions This mapping of atopic eczema reviews is a valuable resource. It will help healthcare practitioners, guideline writers, information specialists, and researchers to quickly identify relevant up-to-date evidence in the field for improving patient care.

Background One in five children visiting a homeopathic physician suffers from atopic eczema. Objectives We aimed to examine the long-term effectiveness, safety and costs of homoeopathic vs. conventional treatment in usual medical care of children with atopic eczema. Methods In this prospective multi-centre comparative observational non-randomized rater-blinded study, 135 children (48 homoeopathy, 87 conventional) with mild to moderate atopic eczema were included by their respective physicians. Depending on the specialisation of the physician, the primary treatment was either standard conventional treatment or individualized homeopathy as delivered in routine medical care. The main outcome was the SCORAD (SCORing Atopic Dermatitis) at 36 months by a blinded rater. Further outcomes included quality of life, conventional medicine consumption, safety and disease related costs at six, 12 and 36 months after baseline. A multilevel ANCOVA was used, with physician as random effect and the following fixed effects: age, gender, baseline value, severity score, social class and parents’ expectation. Results The adjusted mean SCORAD showed no significant differences between the groups at 36 months (13.7 95% CI [7.9–19.5] vs. 14.9 [10.4–19.4], p = 0.741). The SCORAD response rates at 36 months were similar in both groups (33% response: homoeopathic 63.9% vs. conventional 64.5%, p = 0.94; 50% response: 52.0% vs. 52.3%, p = 0.974). Total costs were higher in the homoeopathic versus the conventional group (months 31–36 200.54 Euro [132.33–268.76] vs. 68.86 Euro [9.13–128.58], p = 0.005). Conclusions Taking patient preferences into account, while being unable to rule out residual confounding, in this long-term observational study, the effects of homoeopathic treatment were not superior to conventional treatment for children with mild to moderate atopic eczema, but involved higher costs.

Few studies have simultaneously addressed the importance of age of onset and persistence of eczema for the subsequent development of asthma and hay fever, particularly into early adulthood. A high-risk birth cohort was recruited comprising 620 infants, who were then followed up frequently until 2 years of age, annually from age 3 to 7, then at 12 and 18 years, to document any episodes of eczema, current asthma, and hay fever. The generalized estimation equation technique was used to examine asthma and hay fever outcomes at 6 (n = 325), 12 (n = 248) and 18 (n = 240) years, when there was consistency of associations across the follow-ups. Very early-onset persistent (onset <6 months, still present from 2 to 5 years) eczema was related to current asthma (adjusted OR = 3.2 [95% CI = 1.7-6.1]), as was very early-onset remitting eczema (onset <6 months but not present from 2-5 years, OR = 2.7, 95% CI = 1.0-7.2) and early-onset persistent eczema (onset from 6-24 months, OR = 2.3, 95% CI = 1.2-4.7). Late-onset eczema (commenced from 2-5 years) was associated with increased risk of asthma at 12 years (OR = 3.0, 95% CI=1.1-8.2) but not at age 6 years. Only very early-onset persistent eczema was associated with increased risk of hay fever (aOR = 2.4, 95% CI = 1.4-4.1). Eczema which commences in early infancy and persists into toddler years is strongly associated with asthma, and to a lesser extent hay fever, in high-risk children. If these associations are causal, prevention of early-life eczema might reduce the risk of respiratory allergy. © 2017 EAACI and John Wiley and Sons A/S. Published by John Wiley and Sons Ltd.

Atopic eczema and the filaggrin story.

PubMed

Brown, Sara J; Irvine, Alan D

2008-06-01

The discovery that null mutations in the filaggrin gene (FLG) are associated with atopic eczema represents the single most significant breakthrough in understanding the genetic basis of this complex disorder. The association has been replicated in multiple independent studies during the past 2 years with the use of various methodologies, from populations in Europe, the United States, and Japan. Filaggrin plays a key role in epidermal barrier function, and its association with atopic eczema emphasizes the importance of barrier dysfunction in eczema pathogenesis. This review aims to summarize the current state of knowledge regarding the role of FLG mutations in ichthyosis vulgaris, atopic eczema, and other skin disorders, with an emphasis on potential clinical applications. Further research is needed to clarify the precise role of filaggrin in skin and systemic atopic disease, to pave the way for novel therapeutic interventions.

Epidemiologic evidence of the association between maternal intake of dairy foods, calcium, and vitamin D during pregnancy and childhood allergic disorders is inconclusive. To examine the association between maternal intake of dairy foods, calcium, and vitamin D during pregnancy and childhood allergic disorders in Japanese children aged 23 to 29 months. Study participants were 1,354 mother-child pairs. Maternal intake during pregnancy was assessed with a validated diet history questionnaire administered between April 2007 and March 2008. Wheeze and eczema, defined according to criteria of the International Study of Asthma and Allergies in Childhood, and physician-diagnosed asthma and atopic eczema were assessed via a questionnaire completed by mothers. Higher maternal intake of total dairy products during pregnancy was significantly associated with a reduced risk of infantile eczema (adjusted odds ratio [OR] between extreme quartiles, 0.64; 95% confidence interval [CI], 0.42-0.98). Higher maternal intake of cheese during pregnancy was significantly related to a reduced risk of physician-diagnosed infantile asthma (adjusted OR between extreme quartiles, 0.44; 95% CI, 0.18-0.97). Maternal intake levels of yogurt and calcium during pregnancy were significantly inversely associated with physician-diagnosed infantile atopic eczema (adjusted ORs between extreme quartiles, 0.49 and 0.34; 95% CI, 0.20-1.16 and 0.12-0.84; P for trend = .01 and .03, respectively). Maternal intake of vitamin D during pregnancy was significantly positively associated with infantile eczema (adjusted OR between extreme quartiles, 1.63; 95% CI, 1.07-2.51). Higher maternal intake of total dairy products, cheese, yogurt, and calcium during pregnancy may reduce the risk of infantile eczema, physician-diagnosed asthma, physician-diagnosed atopic eczema, and physician-diagnosed atopic eczema, respectively. Higher maternal intake of vitamin D during pregnancy may increase the risk of infantile eczema. Copyright © 2014 American College of Allergy, Asthma & Immunology. Published by Elsevier Inc.

Interest has increased in the possibility that maternal dietary intake during pregnancy might influence the development of allergic disorders in children. The present prospective study examined the association of maternal intake of selected foods high in fatty acids and specific types of fatty acids during pregnancy with the risk of suspected atopic eczema among Japanese infants aged 3-4 months. Subjects were 771 mother-child pairs. Information on maternal dietary intake during pregnancy was assessed with a validated self-administered diet history questionnaire. The term 'suspected atopic eczema' was used to define an outcome based on results of our questionnaire completed by mothers 3-4 months postpartum. The risk of suspected atopic eczema was 8.4% (n = 65). Higher maternal intake of meat during pregnancy was significantly associated with an increased risk of suspected atopic eczema in the offspring: the multivariate odds ratio (OR) for the highest vs. lowest quartile was 2.59 [95% confidence interval (CI): 1.15-6.17, p for trend = 0.01]. The positive association was strengthened when the definition of the outcome was confined to a definite physician's diagnosis of atopic eczema (n = 35): the multivariate OR between extreme quartiles was 3.53 (95% CI: 1.19-12.23, p for trend = 0.02). No material exposure-response relationships were observed between maternal intake of eggs, dairy products, fish, total fat, saturated fatty acids, monounsaturated fatty acids, n-3 polyunsaturated fatty acids, alpha-linolenic acid, eicosapentaenoic acid, docosahexaenoic acid, n-6 polyunsaturated fatty acids, linoleic acid, arachidonic acid and cholesterol and the ratio of n-3 to n-6 polyunsaturated fatty acid consumption and the risk of suspected atopic eczema. Higher maternal meat intake may increase the risk of infantile atopic eczema, whereas we found no evidence that maternal intake of fish and n-3 polyunsaturated fatty acids are preventive against infantile atopic eczema.

Background: The prevalence of eczema varies markedly across the globe. It is unclear whether the geographic variation is due to race and/or ethnic differences, environmental exposures, or genetic factors. Objective: We investigated the effects of ethnicity and environmental exposures on eczema in Hispanic white and non-Hispanic white children who participated in the Southern California Children's Health Study. Methods: We performed a cross-sectional study with sociodemographic predictors and environmental exposures among Hispanic white and non-Hispanic white children ages 4–8 years enrolled in the Children's Health Study, 2002–2003. Results: Eczema prevalence differed by ethnicity: Hispanic whites showed lower prevalence (13.8%) compared with non-Hispanic whites (20.2%), and adjustment for sociodemographic factors did not account for the ethnic difference (odds ratio [OR] 0.79 [95% confidence interval {CI}, 0.65–0.95]). Parental history of allergic disease had a larger effect in Hispanic whites than in non-Hispanic whites (p for interaction = 0.005). High maternal education level (OR 1.46 [95% CI, 1.14–1.87]), parental history of allergic disease (OR 2.21 [95% CI, 1.78–2.76]), and maternal smoking during pregnancy (OR 1.44 [95% CI, 1.06–1.95]) increased the risk of eczema. Indoor environmental factors (e.g., mold, water damage, humidifier use) increased the risk of eczema in non-Hispanic whites independent of a parental history of allergic disease, but, in Hispanic whites, increased risks were observed, primarily in children without a parental history of allergic disease. Conclusion: Hispanic white children in southern California had a lower prevalence of eczema than non-Hispanic whites, and this ethnic difference was not accounted for by sociodemographic differences. The effects of a parental history of allergic disease and indoor environmental exposures on eczema varied by ethnicity, which indicated that the etiology of eczema may differ in Hispanic whites and in non-Hispanic whites.

Although recent studies suggest that eczema in early childhood is important in the development of food allergy, the importance of the timing of eczema onset has not been fully clarified. This study aim to identify an association between the timing of eczema onset and development of food allergy in a prospective birth cohort study. Data were obtained from the Tokyo Children's Health, Illness and Development (T-CHILD) study, which is a hospital-based birth cohort study currently in progress in Japan. A total of 1550 children were born to the recruited women. Outcome data for children were collected from questionnaires completed at 6 months, 1 and 3 years of age. Association between the timing of eczema onset and development of food allergy was estimated by logistic regression analyses. All analysis were performed using SPSS software with a two-sided 5% significance level. Eczema in the first year of life was a significant risk factor in multivariate analysis (aOR 3.90, 95% CI 2.34-6.52, p<0.001). In each age (by month) stratum, infants with onset of eczema within the first 1-2 months after birth had the highest risk of food allergy at 3 years of age (aOR 6.61, 95% CI 3.27-13.34, p<0.001). Infants with early eczema onset (especially within the first 1-4 months after birth) were found to have an increased risk of developing food allergy at 3 years of age. Our findings may contribute to a better understanding of the timing of eczema onset as a potentially modifiable risk factor and to defining those who may need to be on guard for food allergy.

Genetic and environmental factors are known to be related to the development of childhood eczema. Our aim was to assess the environmental factors associated with the prevalence of eczema among children using a web-based survey. In June 2012, we conducted a nation-wide web-based survey to identify the prevalence and characteristics of allergic diseases among Japanese children. The prevalence of allergic diseases including eczema was assessed using the International Study of Asthma and Allergies in Childhood core questionnaire. The associations between eczema prevalence and environmental factors, as well as those between background characteristics and comorbid allergic diseases among 6-12 year old children were assessed. A total of 28,348 children were included in the analysis. The prevalence of current eczema was 13.0%. Current eczema was significantly associated with a higher prevalence of wheeze, rhinitis, and food allergy. In multiple logistic regression models, birth during autumn (aOR: 1.18 95%CI: 1.06-1.31) or winter (aOR: 1.21 95%CI: 1.08-1.34), duration of exclusive breastfeeding for at least 6 months (aOR: 1.14 95%CI: 1.06-1.23), and ownership of a pet from infancy (aOR: 2.61 95%CI: 1.68-4.07) were also associated with a higher prevalence of eczema. The prevalence was lower in those with a high annual household income (aOR: 0.90 95%CI: 0.81-0.99) and 2 or more siblings (aOR: 0.86 95%CI: 0.76-0.97). Duration of breastfeeding, season of birth, pet ownership, household income, and the number of siblings were associated with the prevalence of childhood eczema in a nationwide web survey.

Modes of infant feeding such as direct and indirect breastfeeding, and formula feeding, and their combinations may play a role in child health. The aim was to investigate which feeding patterns in the first 6 months pose risks of eczema/skin allergy in children up to 6 years compared to direct breastfeeding for at least 3 months. The Infant Feeding Practices Study II in the United States and its 6-year follow-up provided data on feeding modes in infancy and doctor's diagnosed eczema/skin allergy in the first 6 years of life (1387 infants), based on parental reports. Different feeding patterns were identified. Log-linear models were used to estimate prevalence ratios (PRs) of feeding patterns for doctor's diagnosed eczema/skin allergy in the first 6 years of life, adjusting for confounders. Compared to "direct breastfeeding for at least 3 months" (DBF3m), the combination of "direct feeding at the breast (DBF), pumping and feeding breast milk (BM), and formula (FF) in the first months" (DBF/BM/FF) showed a statistically significant higher risk of eczema/skin allergy in the first 6 years of life (PR = 1.46), adjusting for confounders. DBF combined with BM for the first 3 months followed by mixed feeding also had an increased risk (PR = 1.26), although not statistically significant. Formula feeding introduced since birth had no effect on eczema. Among the confounders, paternal eczema and race/ethnicity (Hispanic vs White) were associated with a higher risk of eczema/skin allergy. Mixed infant feeding may carry a higher risk of eczema/skin allergy compared to direct feeding at the breast. The recent epidemic of pumping and feeding in the United States and the use of mixed infant feeding modes requires additional studies to provide appropriate and renewed assessments of the risks of feeding modes for the future development of allergies. © 2017 John Wiley & Sons Ltd.

Long-term follow-up was completed in 84 mother-infant pairs of 118 women who completed a randomized controlled trial of prenatal supplementation with EPA- or DHA-rich fish oil or soy oil placebo. The goal of this study was to determine whether prenatal omega-3 fatty acid supplementation protects offspring against development of early childhood allergies. Assessment of childhood allergic/atopic disease among offspring at age 36 months was performed by maternal interview using the National Health Interview Survey (NHIS) questions for childhood digestive allergies, wheezing, eczema or skin allergy, and respiratory allergy. Multiple logistic regressions examined the association between prenatal supplementation and childhood outcomes, adjusted for covariates. Eczema was reported in 26/84 (31%) of offspring at age 36 months, and was significantly more prevalent in the omega-3 supplementation groups vs. placebo: EPA 13/31 (41.9%); DHA 10/26 (38.5%); placebo 3/27 (11.1%), p=0.019. Compared to placebo, EPA and DHA were associated with ≥5 times risk of offspring eczema [odds ratios (ORs): EPA 5.8 (95% CI 1.4-23.3); DHA 5.0 (95% CI 1.2-21.0)]. After adjusting for other potential risk factors (race, birth weight, vaginal/Cesarean delivery, and maternal eczema) the magnitudes of association for omega-3 supplementation increased: EPA OR 8.1 (95% CI 1.4-45.6); DHA OR 9.6 (95% CI 1.6-58.5). Maternal eczema was also significantly associated with offspring eczema in the adjusted model: OR 10.8 (95% CI 2.1-54.3). Contrary to our hypothesis, acids supplementation compared to soy oil was associated with a substantial increase in risk of childhood eczema. This association was not observed on childhood respiratory or digestive outcomes. It is unclear if these findings were driven by unfavorable effects of omega-3s, or whether there may have been unanticipated protective effects of the soy-based placebo with regards to eczema.

Symptoms of atopic dermatitis are often affected by environmental irritants. Modulation of potential irritants may benefit such symptoms. The purpose of this study was to evaluate the impact of a novel silklike bedding fabric for persons with mild to moderate atopic dermatitis. Participants with mild to moderate atopic dermatitis were provided a bedsheet set. Eczema Area and Severity Index and Investigator Global Assessment were the primary outcome measures. Visual Analog Scale for itch and a quality of life were also evaluated. The Wilcoxon signed rank test indicated a significant decrease in severity, with the Investigator Global Assessment score decreasing from 2.05 to 1.74 at week 8 (p = 0.03), the Eczema Area and Severity Index decreasing from 2.63 at baseline to 2.19 (p = 0.014), and the itching score decreasing from 3.97 to 3.00 (p = 0.010). An increase in the study-specific quality of life index was also observed, changing from -0.08 (no change in quality of life) to 1.23 (some improvement) (p < 0.0001). Atopic dermatitis is commonly recalcitrant to therapy and synthetic silklike bed linens may have value as another option for the treatment of this disease. This pilot study demonstrated promising results that warrant confirmation in controlled clinical studies.

Background In recent years, it has been proposed that the primary mechanism for the development of food allergies is percutaneous sensitization. Since 2010, in Japan, the number of immediate-type wheat allergy due to hydrolyzed wheat protein has dramatically increased among those who have been using soap containing hydrolyzed wheat. This incidence supports the hypothesis that food allergens arise through percutaneous sensitization. Clinical Summary A 25-year-old man (case 1) and an 18-year-old girl (case 2) with atopic dermatitis visited our Department because of food allergy and hand eczema. After starting their work with fish, severe itchy eczema appeared on their hands. They subsequently started to experience oral allergic symptoms, intraoral itchiness and dyspnea after eating fish. Specific IgE antibodies were detected for many fishes, and skin prick tests showed positive reactions for a variety of fishes in both cases. Furthermore, the fluorescence intensities of specific IgE antibodies against parvalbumin from various types of fish in microarray immunoassay analysis showed positive reactions. We diagnosed them as contact urticaria caused by percutaneous sensitization to parvalbumin through job-related physical contact with fish. Conclusion The patients' histories and findings indicate the possibility of percutaneous sensitization through occupational exposure to parvalbumin, leading to food allergy. PMID:26464568

Occupational allergic contact dermatitis from epoxy resin in a golf club repairman.

A golfer presented with facial and hand eczema. He had exacerbations of his hand eczema prior to golf tournaments. Being an authorized golf club repairman, he had been working with a two-part glue containing an epoxy resin (ER) based on diglycidyl ether of bisphenol A (DGEBA) and the hardener diethylenetriamine (DETA) for approximately 4 years before he developed any skin problems. He was patch-tested with the standard, which contains an ER based on DGEBA (DGEBA-R), epoxy (containing DETA), and rubber glove series and had positive reactions to DGEBA-R only. Other work materials (a latex glove, a golf glove made of leather, and part of the handle of his own golf club "as is" and in a methyl tert-butyl ether extract) were tested, with negative results. Allergic contact dermatitis from ER affects the skin by direct contact; the dermatitis is usually localized to the hands and forearms. If the face and eyelids are involved, the dermatitis may be due to exposure to airborne hardeners or reactive diluents, exposure to airborne dust from residual monomers, or ectopic allergic reactions. Our repairman had sandpapered an old glued surface, which may have led to possible airborne dust formation, thus explaining the facial eczema. Therefore, a worker with contact allergy to ER may continue working provided the skin is protected from contamination.

Studies investigating the association between Enterobius vermicularis and allergic conditions have shown conflicting results. This study was conducted to test for any such associations in Norwegian children. Parents were asked to answer questionnaires concerning their children's history of allergies, wheezing or eczema and pinworm infections. Current pinworm infections were diagnosed by microscopic examination of anal scotch tape samples. The data were analysed using logistic regression. Atopic eczema, allergy or wheezing was reported to be confirmed by a physician in 23% of the children (84/364). A possible association between current pinworm infections and food allergy was found, with 17·5% of children without food allergy testing positive for pinworms, compared to 36·8% of children with food allergy (odds ratio 2·9, 95% confidence interval 1·1-8·0). No association was found between past pinworm treatments and present atopic conditions. The association between current E. vermicularis infections and food allergy warrants further study.

There is a need to improve the quality of communication between clinicians and parents of young patients with atopic eczema (AE). To create a tool to measure the suffering that caregivers experience in association with their child's AE (Caregiver Pictorial Representation of Illness and Self-Measure, Caregiver-PRISM), assess the validity and reliability, and identify factors associated with caregiver suffering. Caregiver-PRISM was administered to 45 parents of patients from an AE outpatient service (Padua, Italy). Caregiver-PRISM had a good test-retest reliability (r = 0.85; t7 = 4.13; p < 0.05), content validity and construct validity when used in parents of AE children. Parents with a less positive family affective climate, higher education, or with children following a diet experienced higher suffering associated with their child's AE, demonstrated by lower Caregiver-PRISM scores (p < 0.05). Our results support the use of Caregiver-PRISM in parents of AE patients to assess suffering associated with patients' illness. © 2016 S. Karger AG, Basel.

The prevalence of eczema is increasing in industrialized nations. Limited evidence has shown the association of DNA methylation (DNA-M) with eczema. We explored this association at the epigenome-scale to better understand the role of DNA-M. Data from the first generation (F1) of the Isle of Wight (IoW) birth cohort participants and the second generation (F2) were examined in our study. Epigenome-scale DNA methylation of F1 at age 18 years and F2 in cord blood was measured using the Illumina Infinium HumanMethylation450 Beadchip. A total of 307,357 cytosine-phosphate-guanine sites (CpGs) in the F1 generation were screened via recursive random forest (RF) for their potential association with eczema at age 18. Functional enrichment and pathway analysis of resulting genes were carried out using DAVID gene functional classification tool. Log-linear models were performed in F1 to corroborate the identified CpGs. Findings in F1 were further replicated in F2. The recursive RF yielded 140 CpGs, 88 of which showed statistically significant associations with eczema at age 18, corroborated by log-linear models after controlling for false discovery rate (FDR) of 0.05. These CpGs were enriched among many biological pathways, including pathways related to creating transcriptional variety and pathways mechanistically linked to eczema such as cadherins, cell adhesion, gap junctions, tight junctions, melanogenesis, and apoptosis. In the F2 generation, about half of the 83 CpGs identified in F1 showed the same direction of association with eczema risk as in F1, of which two CpGs were significantly associated with eczema risk, cg04850479 of the PROZ gene (risk ratio (RR) = 15.1 in F1, 95 % confidence interval (CI) 1.71, 79.5; RR = 6.82 in F2, 95 % CI 1.52, 30.62) and cg01427769 of the NEU1 gene (RR = 0.13 in F1, 95 % CI 0.03, 0.46; RR = 0.09 in F2, 95 % CI 0.03, 0.36). Via epigenome-scaled analyses using recursive RF followed by log-linear models, we identified 88 CpGs associated with eczema in F1, of which 41 were replicated in F2. Several identified CpGs are located within genes in biological pathways relating to skin barrier integrity, which is central to the pathogenesis of eczema. Novel genes associated with eczema risk were identified (e.g., the PROZ and NEU1 genes).

Eczema, asthma, and rhinitis affect a large proportion of children, but their prevalence varies with age. IgE antibodies are also common in the pediatric population. However, the links between IgE, disease, and trajectories are unclear. To better understand the links between sensitization and disease, we studied IgE sensitization ever in relation to eczema, asthma, and rhinitis, in children followed up to 16 years of age. From the Swedish population-based birth cohort BAMSE, 2607 children were included. Parental reports from six time points between 1 and 16 years were used to identify children with eczema, asthma, and rhinitis. Blood was collected at 4, 8, and 16 years, and sensitization ever was defined as allergen-specific IgE ≥0.35 kUA /l to common food and/or inhalant allergens at any time point. Odds ratios for eczema, asthma, rhinitis, and multimorbidity in relation to sensitization ever were calculated using generalized estimating equations. Fifty-one percent were sensitized at least once up to 16 years. Almost a quarter of ever-sensitized children did not have any disease. After adjustment for potential confounders, sensitization ever was significantly associated with the following: (i) eczema throughout childhood, (ii) multimorbidity of eczema, asthma, and rhinitis from 1 to 16 years (OR for multimorbidity: 5.11, 95% CI: 3.99-6.55), (iii) asthma and rhinitis from 4 to 16 years of age. Specific IgE is strongly associated with eczema and allergic multimorbidity throughout childhood and with asthma and rhinitis from age 4 years. However, 23% of the children with IgE sensitization do not develop any disease in childhood. © 2015 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

We aim to investigate associations of the child's individual characteristics, building characteristics, home environmental exposures, family lifestyle behaviors, and dietary habits on childhood eczema during lifetime-ever and in the last year before the survey. During April 2011-April 2012, we conducted a cross-sectional study and collected 13,335 parents-reported questionnaires of 4-6-year-old children from 72 kindergartens in Shanghai, China. Logistic regression model was used to investigate associations. After adjusted for sex, age, family history of atopy, and questionnaire reporter, the factors which were strongly associated (increased odds >30% and p value <0.05) with lifetime-ever eczema included mother employed during pregnancy (adjusted OR 1.33), residence renovated during pregnancy (1.49) and in the child's first year of life (1.31), using laminate (1.58) and solid (1.42) wood as material of floor covering (compared to using cement), residence located in urban district (1.38), and dampness-related exposures in the early residence (mold spots/stains: 1.41; mold odor: 1.41) and in the current residence (water damage: 1.33; damp stains: 1.34; mold spots: 1.32; and windows pane condensation: 1.31). Parental smoking, pet-keeping, and incense-burning had no significant associations with childhood eczema. Similar associations were found for eczema in the last year before the survey. Families with sick children likely changed lifestyle behaviors and dietary habits. Childhood eczema could be influenced by many household environmental and non-environmental factors. Exposures during early lifetime likely have greater impact on childhood eczema than current exposures. Associations of lifestyle behaviors and dietary habits with childhood eczema could be modified by family avoidance behaviors.

Objective We sought to explore parents and carers’ experiences of searching for information about childhood eczema on the internet. Design A qualitative interview study was carried out among carers of children aged 5 years or less with a recorded diagnosis of eczema. The main focus of the study was to explore carers’ beliefs and understandings around eczema and its treatment. As part of this, we explored experiences of formal and informal information seeking about childhood eczema. Transcripts of interviews were analysed thematically. Setting Participants were recruited from six general practices in South West England. Participants Interviews were carried out with 31 parents from 28 families. Results Experiences of searching for eczema information on the internet varied widely. A few interviewees were able to navigate through the internet and find the specific information they were looking for (for instance about treatments their child had been prescribed), but more found searching for eczema information online to be a bewildering experience. Some could find no information of relevance to them, whereas others found the volume of different information sources overwhelming. Some said that they were unsure how to evaluate online information or that they were wary of commercial interests behind some information sources. Interviewees said that they would welcome more signposting towards high quality information from their healthcare providers. Conclusions We found very mixed experiences of seeking eczema information on the internet; but many participants in this study found this to be frustrating and confusing. Healthcare professionals and healthcare systems have a role to play in helping people with long-term health conditions and their carers find reliable online information to support them with self-care.

Cross-sectional studies suggest an association between eczema and mental health problems, possibly modified by sleeping problems, but prospective evidence is missing. We aimed to prospectively investigate the relationship between infant eczema (within first 2 years of age), infant sleeping problems (within first 2 years of age), and the risk of mental health problems at 10 years of age. Between 1997 and 1999, a population-based birth cohort was recruited in Munich, Leipzig, Wesel, and Bad Honnef, Germany, and followed until 10 years of age. Physician-diagnosed eczema, parent-reported sleeping problems, and known environmental risk factors for atopy were regularly assessed until 10 years of age. Mental health was measured using the Strengths and Difficulties Questionnaire (parent version) at 10 years of age. We applied logistic regression modeling adjusting for environmental and lifestyle factors, allergic comorbidity, and family history of eczema. From the original cohort of 3097 neonates, 1658 (54%) were followed until age 10, while 1578 (51%) were eligible for analysis. In the fully adjusted model, children with infant eczema were at increased risk of hyperactivity/inattention at 10 years of age [odds ratio (OR) 1.78; 95% confidence interval (95% CI) 1.02-3.09]. Infant eczema with concurrent sleeping problems predicted emotional problems [OR 2.63; 95% confidence interval (95% CI) 1.20-5.76] and conduct problems (OR 3.03; 95% CI 1.01-9.12) at 10 years of age. Infant eczema with concurrent sleeping problems appears to be a risk factor for the development of mental health problems. © 2010 John Wiley & Sons A/S.

Tinea incognito (TI) is a dermatophytic infection which has lost its typical clinical appearance because of improper use of steroids or calcineurin inhibitors. The incidence of TI is increasing nowadays. We conducted retrospective review on 283 patients with TI from 25 dermatology training hospitals in Korea from 2002-2010 to investigate the demographical, clinical, and mycological characteristics of TI, and to determine the associated risk factors. More than half (59.3%) patients were previously treated by non-dermatologists or self-treated. The mean duration of TI was 15.0 ± 25.3 months. The most common clinical manifestations were eczema-like lesion, psoriasis-like, and lupus erythematosus-like lesion. The trunk and face were frequently involved, and 91 patients (32.2%) also had coexisting fungal infections. Among 67 isolated strains, Trichophyton rubrum was the most frequently detected (73.1%). This is the largest study of TI reported to date and the first investigational report concerning TI in Korea. We suggest that doctors should consider TI when a patient has intractable eczema-like lesions accompanied by tinea pedis/unguium. Furthermore, there should be a policy change, which would make over-the-counter high-potency topical steroids less accessible in some countries, including Korea.

Recently named one of the most influential phone applications, Instagram continues to grow in popularity [1]. Instagram consists of images and video posts, making it ideal for education and communication within the visual field of dermatology. In this study, we seek to determine the presence of dermatology-related content with regard to the most common cutaneous diseases of the world. We searched the account types and hashtags associated with the eight most common skin diseases globally as identified by the Global Burden of Disease (GBD) study by Hollenstein et al.: eczema, psoriasis, acne,pruritus, alopecia, decubitus ulcer, urticaria, andscabies [9]. The majority of Instagram accounts included patient experiences (n=73), private accounts(n=52), and disease advocacy and awareness groups(n=20), (total n=221). We further investigated over 2 million skin disease hashtags. The greatest numbersof hashtags were the following: #acne (n = 1,622,626),#alopecia (n = 317,566), and #eczema (n = 196,115). Our results demonstrate that patients interact withone another through Instagram. As social networking platforms become more frequently used as a source of information for patients and patient support, medical professionals must gain awareness of content available through Instagram and consider it as a means to educate the public.

Dermatology in-house call is uncommon in the Spanish national health system. The objective of the present study was to define the groups of dermatologic diseases and conditions most frequently seen in the emergency department and to evaluate the need for dermatology in-house call in the training of medical residents. We performed a descriptive study of all patients who attended the emergency department with a skin complaint during a 1-year period (June 2013 to May 2014) and were assessed by 9 dermatology residents. The study variables were date/day, sex, age, diagnosis, special surgical procedures, additional laboratory tests, and need for hospitalization and/or follow-up. We also evaluated patients attending their first scheduled visit to the dermatologist between January and June 2014 in order to compare the most frequent conditions in both groups. A total of 3084 patients attended the emergency room with a skin complaint (5.6% of all visits to the emergency department), and 152 different diagnoses were made. The most frequent groups of diseases were infectious diseases (23%) and eczema (15.1%). The specific conditions seen were acute urticaria (7.6%), contact dermatitis (6.1%), and drug-induced reactions (4.6%). By contrast, the most frequent conditions seen in the 1288 patients who attended a scheduled dermatology appointment were seborrheic keratosis (11.9%), melanocytic nevus (11.5%), and actinic keratosis (8%). A follow-up visit was required in 42% of patients seen in the emergency department. Fourth-year residents generated the lowest number of follow-up visits. We found that infectious diseases and eczema accounted for almost 40% of all emergency dermatology visits. Our results seem to indicate that the system of in-house call for dermatology residents is very useful for the hospital system and an essential component of the dermatology resident's training program.

Flares in childhood eczema.

PubMed

Langan, S M

2009-01-01

Eczema is a major public health problem affecting children worldwide. Few studies have directly assessed triggers for disease flares. This paper presents evidence from a published systematic review and a prospective cohort study looking at flare factors in eczema. This systematic review suggested that foodstuffs in selected groups, dust exposure, unfamiliar pets, seasonal variation, stress, and irritants may be important in eczema flares. We performed a prospective cohort study that focused on environmental factors and identified associations between exposure to nylon clothing, dust, unfamiliar pets, sweating, shampoo, and eczema flares. Results from this study also demonstrated some new key findings. First, the effect of shampoo was found to increase in cold weather, and second, combinations of environmental factors were associated with disease exacerbation, supporting a multiple component disease model. This information is likely to be useful to families and may lead to the ability to reduce disease flares in the future.

To evaluate practice patterns in the management of cow's milk protein allergy (CMPA) and associated economic burden of disease on health service in Turkey. This study was based on experts' views on the practice patterns in management of CMPA manifesting with either proctocolitis or eczema symptoms and, thereby, aimed to estimate economic burden of CMPA. Practice patterns were determined via patient flow charts developed by experts using the modified Delphi method for CMPA presented with proctocolitis and eczema. Per patient total 2-year direct medical costs were calculated, including cost items of physician visits, laboratory tests, and treatment. According to the consensus opinion of experts, 2-year total direct medical cost from a payer perspective and societal perspective was calculated to be $US2,116.05 and $US2,435.84, respectively, in an infant with CMPA presenting with proctocolitis symptoms, and $US4,001.65 and $US4,828.90, respectively, in an infant with CMPA presenting with eczema symptoms. Clinical nutrition was the primary cost driver that accounted for 89-92% of 2-year total direct medical costs, while the highest total direct medical cost estimated from a payer perspective and societal perspective was noted for the management of an exclusively formula-fed infant presenting either with proctocolitis ($US3,743.85 and $US4,025.63, respectively) or eczema ($US6,854.10 and $US7,917.30, respectively). The first line use of amino acid based formula (AAF) was associated with total direct cost increment $US1,848.08 and $US3,444.52 in the case of proctocolitis and eczema, respectively. Certain limitations to this study should be considered. First, being focused only on direct costs, the lack of data on indirect costs or intangible costs of illness seems to be a major limitation of the present study, which likely results in a downward bias in the estimates of the economic cost of CMPA. Second, given the limited number of studies concerning epidemiology and practice patterns in CMPA in Turkey, use of expert clinical opinion of the panel members rather than real-life data on practice patterns that were used to identify direct medical costs might raise a concern with the validity and reliability of the data. Also, while this was a three-step study with six experts included in the first stage (developing local guidelines for diagnosis, treatment, and follow-up of infants with CMPA in Turkey) and 410 pediatricians included in the second stage (a cross-sectional questionnaire-survey to determine pediatricians' awareness and practice of CMPA in infants and children), only four members were included in the present Delphi panel, which allows a limited discussion. Third, lack of sensitivity analyses and exclusion of indirect costs and costs related to alterations in quality of life, behavior of infants, and general well-being of infants and their parents from the cost-analysis seems to be another limitation that may have caused under-estimation of relative cost-effectiveness of the formulae. Fourth, calculation of costs per local guidelines rather than real-life practice patterns is another limitation that, otherwise, would extend the knowledge achieved in the current study. Notwithstanding these limitations, the present expert panel provided practice patterns in the management of CMPA and an estimate of the associated costs, depending on the symptom profile at initial admission for the first time in Turkey. In conclusion, in providing the first health economic data on CMPA in Turkey, the findings revealed that CMPA imposes a substantial burden on the Turkish healthcare system from both a payer perspective and societal perspective, and indicated clinical nutrition as a primary cost driver. Management of infants presenting with eczema, exclusively formula-fed infants, and first line use of AAF were associated with higher estimates for 2-year direct medical costs.

Increased expression of RANTES, CCR3 and CCR5 in the lesional skin of patients with atopic eczema.

Atopic eczema (AE) is a relapsing inflammatory disease based on IgE sensitization and characterized by peripheral blood eosinophilia and eosinophil infiltration into the lesional skin. In the patch test reaction of AE by allergens, an increased infiltration of activated eosinophils has been demonstrated peaking at 24-48 h. Regulated on activation normal T cell expressed and secreted (RANTES/CCL5) is a chemokine that induces eosinophil migration, and CCR3 and CCR5 are the receptors of RANTES. In order to further clarify the pathomechanisms of eosinophil infiltration in ongoing chronic inflammation in the skin of patients with AE and its relation to disease severity, we examined the expression of RANTES and its receptors CCR3 and CCR5 in challenged and unchallenged lesional skin of AE. We examined the number of RANTES+ cells, CCR3+ cells, CCR5+cells, activated (EG2+) eosinophils and CD3+ T cells in normal skin of healthy volunteers, and in challenged lesional skin (24 h after mite patch test) as well as unchallenged lesional skin of AE patients by immunohistochemistry. The cellular source of RANTES, CCR3 and CCR5 was analyzed by double immunohistochemistry using specific antibodies to RANTES, CCR3 or CCR5, and antibodies to ECP (EG2) or CD3. The numbers of RANTES+ cells, CCR3+ cells, CCR5+ cells, EG2+ cells and CD3+ cells were all significantly increased in challenged (mite patch-tested) lesional skin of AE patients as compared to those in unchallenged lesional skin and normal skin. The numbers of these cells in unchallenged lesional skin were greater than those in normal skin. The number of EG2+ cells in the unchallenged lesional skin correlated with both the peripheral blood eosinophil count and the SCORAD index. The number of EG2+ cells in challenged lesional skin correlated with the number of CCR5+ cells. Activated eosinophils and T cells expressed RANTES and various proportions of these cells were CCR3+ and CCR5+ in both challenged and unchallenged lesional skin. Taken together, these results suggest that RANTES as well as its receptors CCR3 and CCR5 may play important roles in the orchestration of eosinophil infiltration in ongoing chronic inflammation in AE, and also reflect the severity of disease.

Novel unconventional therapeutic approaches to atopic eczema.

PubMed

Worm, M; Henz, B M

2000-01-01

Atopic eczema is a chronic, recurrent, multifactorial skin disease, and, accordingly, there are numerous therapeutic options for its symptomatic treatment. Conventional medications are however often unsatisfactory for many patients because of adverse effects on long-term use. For this reason, patients often readily welcome unconventional therapeutic approaches. We present here a selected number of such treatment modalities, namely gamma-linolenic acid, Chinese herbal tea, diets eliminating allergens, pseudoallergens, metal salts and sodium, and bioresonance. When stringent scientific criteria are applied in the evaluation of such study results, none of the reviewed alternative treatments provides unequivocal, convincing evidence of its efficacy, even when double-blind, placebo-controlled studies are available. With Chinese herbal tea, potentially serious adverse effects should be considered as well. Any new type of unconventional therapy should thus be thoroughly evaluated and shown to be equal or superior to conventional treatments with regard to both efficacy and tolerability before it is recommended for use in clinical practice.

Interactions between genetic and environmental factors underlie the immune dysregulation and keratinocyte abnormalities that characterize psoriasis. Among known psoriasis susceptibility loci (PSORS), PSORS1 on chromosome 6 has the strongest association to disease. Altered expression of some PSORS1 candidate genes has been reported but little is known about HLA-C expression in psoriasis. This study compared expression of major histocompatibility complex class Ia and HLA-C in psoriasis, allergic contact eczema, and normal skin. Although HLA-C was abundant in protein extracts from both eczema and psoriasis, a consistent and intriguing difference in the expression pattern was observed; strong immunoreactivity in the basal cell layer, polarized towards the basement membrane in psoriasis, whereas in eczema lesions HLA-C immunostaining was present mostly in suprabasal cells. Inflammatory cells in the dermis were strongly stained in both diseases. Normal skin epithelium showed less intense but similar HLA-C staining as eczema lesions. HLA class Ia expression overall resembled that of HLA-C in all samples. The distinct HLA-C expression patterns in psoriasis and eczema suggest a functional role in the specific psoriasis immune response and not only a general feature of inflammation.

Eczema often precedes the development of asthma in a disease course called the 'atopic march'. To unravel the genes underlying this characteristic pattern of allergic disease, we conduct a multi-stage genome-wide association study on infantile eczema followed by childhood asthma in 12 populations including 2,428 cases and 17,034 controls. Here we report two novel loci specific for the combined eczema plus asthma phenotype, which are associated with allergic disease for the first time; rs9357733 located in EFHC1 on chromosome 6p12.3 (OR 1.27; P=2.1 × 10(-8)) and rs993226 between TMTC2 and SLC6A15 on chromosome 12q21.3 (OR 1.58; P=5.3 × 10(-9)). Additional susceptibility loci identified at genome-wide significance are FLG (1q21.3), IL4/KIF3A (5q31.1), AP5B1/OVOL1 (11q13.1), C11orf30/LRRC32 (11q13.5) and IKZF3 (17q21). We show that predominantly eczema loci increase the risk for the atopic march. Our findings suggest that eczema may play an important role in the development of asthma after eczema.

The aim of this study was to determine self-reported consumption of dermatological pharmaceuticals and quality of life (QoL), measured with Short Form 36, in relation to eczema, acne, psoriasis and other inflammatory skin conditions in the Swedish population. A questionnaire containing questions on the occurrence of skin diseases, health-related QoL and the use of pharmaceuticals was sent to a cross-sectional sample of the Swedish population, age range 18-84 years (n = 8,000). The response rate was 61%. The 1-year prevalence of skin diseases was 30-35%, with females reporting a higher prevalence. The prevalence was 11.5% for eczema other than hand eczema, 10.2% for acne, 7.5% for hand eczema, 3.9% for psoriasis and 3.1% for urticaria. QoL was significantly affected and 25% of females and 19% of males had used a dermatological drug. Compared with hand eczema, persons with psoriasis and other eczema reported significantly more use of topical steroids on prescription and more use of dermatological pharmaceuticals in total. Skin conditions are common; they affect QoL and lead to a high consumption of dermatological drugs; which deserves increased awareness in the society.

[Prevention of atopic eczema. Evidence based guidelines].

Schäfer, T

With an estimated prevalence of 12% for preschool children and 3% for adults, atopic eczema is a serious public health problem. This disease severely jeopardizes quality of life and is associated with considerable costs. Since there is still no causal therapy, primary and secondary prevention are especially important. Here the evidence basis for recommendations on prevention of atopic eczema is discussed on the basis of the first evidence-based consensus guideline (S3) on allergy prevention. This recommends that babies should be breastfed exclusively for at least 4 months and exposure to passive smoking be avoided even during pregnancy; restriction of the maternal diet during pregnancy has no influence, though during breastfeeding it can lower the incidence of eczema among babies at risk. Thereby this measure should be balanced with potential consequences of malnutrition. There seems to be a positive correlation between keeping small rodents (rabbits, guinea pigs), and possibly cats, and the occurrence of atopic eczema, while keeping dogs has no effect or even a protective effect. Avoidance of an unfavorable indoor climate is probably also helpful in preventing eczema. There is no evidence to support deviating from the current recommendations of the standing committee for vaccination.

Recently, D-limonene-based solvents are used as a safe alternative to xylene for histological and cytological application to dissolve paraffin. We report the case of a histopathology technician with a recalcitrant hand contact dermatitis strictly related to the use of a limonene-based solvent agent. Patch tests with SIDAPA (Italian Society of Allergological, Professional and Environmental Dermatology) standard series, limonene-based solvent used by the patient and D- and L-limonene (both oxidized and nonoxidized form) and with Giemsa and methylene blue stains were performed. Patch testing gave positive results to oxidized D- and L-limonene. The patient retired from work and promptly improved and healed the hand eczema. Subsequently, the potential occurrence of limonene oxidation products in the incriminated preparation was investigated using gas chromatography-mass spectrometry. While patch test showed positive reaction to oxidized limonene, chemical analysis failed to detect oxidized limonene in the preparations used by the patient. Considering the strict relation between the use of the preparations and the appearance of symptoms, we can assume that oxidized limonene may be produced during the handling of limonene-based products, especially in the presence of oxidants stains, frequently used in histological laboratories.

Melamine paper is a basic material used in the furniture industry for home and office interiors. Contact allergic dermatitis from melamine formaldehyde resins (MFRs) should be considered in patients who work on melamine paper impregnation lines. We report a case of a 28-year-old female plywood worker who developed eczema on the dorsal side of her hands and wrists after 2 years of working on the melamine paper impregnation line. She had a relevant positive patch-test reaction to MFR, with a negative reaction to formaldehyde. Contact dermatitis due to MFR is not common, and it is usually related to products that are not fully cured or to close contact with intermediate products on the assembly line. Formaldehyde release from MFR can explain most of the positive responses. To our knowledge, this is the first report of MFR contact allergic dermatitis in a worker on a melamine paper impregnation line.

To investigate the effects of the implementation strategy on self-reported hand eczema and preventive behaviour. A randomized controlled trial was performed. A total of 48 departments (n = 1649) were randomly allocated to the multifaceted implementation strategy or the control group. The strategy consisted of education, participatory working groups, and role models. Outcome measures were self-reported hand eczema and preventive behaviour. Data were collected at baseline, and 3, 6, 9 and 12 months of follow-up. Participants in the intervention group were significantly more likely to report hand eczema [odds ratio (OR) 1.45; 95% confidence interval (CI) 1.03-2.04], and they reported significantly less hand washing (B, - 0.38; 95%CI: - 0.48 to - 0.27), reported significantly more frequent use of a moisturizer (B, 0.30; 95%CI: 0.22-0.39) and were more likely to report wearing cotton undergloves (OR 6.33; 95%CI: 3.23-12.41) than participants in the control group 12 months after baseline. The strategy implemented can be used in practice, as it showed positive effects on preventive behaviour. More research is needed to investigate the unexpected effects on hand eczema. © 2014 The Authors. Contact Dermatitis published by John Wiley & Sons Ltd.

Relevance of inhalant and food allergens to the etiology and management of patients with atopic dermatitis

DOE Office of Scientific and Technical Information (OSTI.GOV)

Platts-Mills, T.A.; Mitchell, E.B.; Rowntree, S.

Patients with atopic dermatitis have IgE antibodies to common environmental antigens, both foods and inhalants. Such antibodies are probably relevant and exposure to the corresponding antigens can give rise to eczema. Nevertheless, the mechanisms involved and the role of other etiologies, e.g. contact reactions, remain to be elucidated. Patients with atopic dermatitis should have comprehensive evaluations to determine the role of environmental antigens.

The potential of trivalent and hexavalent chromium to induce and elicit allergic contact dermatitis and the degree of chromium exposure from leather products are reviewed. Chromium dermatitis is often due to exposure in the occupational environment, with cement being one of the most common chromium sources. However, consumer products such as chromium(III)-tanned leather products are also an important source of chromium exposure. Apart from Cr(III), which is used for tanning, leather often also contains trace amounts of Cr(VI), which is formed by oxidation of Cr(III) during the tanning process. In a recent study of the Cr(VI) content of leather products bought on the Danish market, 35% of such articles had a Cr(VI) content above the detection limit of 3 p.p.m., ranging from 3.6 p.p.m. to 14.7 p.p.m. Leachable Cr(III) was detected at levels of 430-980 p.p.m. An examination of available dose-response studies showed that exposure to occluded patch test concentrations of 7-45 p.p.m. Cr(VI) elicits a reaction in 10% of the chromium-sensitive patients. When reviewing repeated open exposure studies, it is seen that either exposure to 5 p.p.m. Cr(VI) in the presence of 1% sodium lauryl sulfate (SLS) or exposure to 10 p.p.m. Cr(VI) alone both elicit eczema in chromium-sensitive patients. The eliciting capacity of Cr(III) has not been systematically investigated but, compared to Cr(VI), much higher concentrations are needed to elicit eczema.

Interactive effect of STAT6 and IL13 gene polymorphisms on eczema status: results from a longitudinal and a cross-sectional study

PubMed Central

2013-01-01

Background Eczema is a prevalent skin disease that is mainly characterized by systemic deviation of immune response and defective epidermal barrier. Th2 cytokines, such as IL-13 and transcription factor STAT6 are key elements in the inflammatory response that characterize allergic disorders, including eczema. Previous genetic association studies showed inconsistent results for the association of single nucleotide polymorphisms (SNPs) with eczema. Our aim was to investigate whether SNPs in IL13 and STAT6 genes, which share a biological pathway, have an interactive effect on eczema risk. Methods Data from two independent population-based studies were analyzed, namely the Isle of Wight birth cohort study (IOW; n = 1,456) and for the purpose of replication the Swansea PAPA (Poblogaeth Asthma Prifysgol Abertawe; n = 1,445) cross-sectional study. Log-binomial regressions were applied to (i) account for the interaction between IL13 (rs20541) and STAT6 (rs1059513) polymorphisms and (ii) estimate the combined effect, in terms of risk ratios (RRs), of both risk factors on the risk of eczema. Results Under a dominant genetic model, the interaction term [IL13 (rs20541) × STAT6 (rs1059513)] was statistically significant in both studies (IOW: adjusted Pinteraction = 0.046; PAPA: Pinteraction = 0.037). The assessment of the combined effect associated with having risk genotypes in both SNPs yielded a 1.52-fold increased risk of eczema in the IOW study (95% confidence interval (CI): 1.05 – 2.20; P = 0.028) and a 2.01-fold higher risk of eczema (95% CI: 1.29 – 3.12; P = 0.002) in the PAPA study population. Conclusions Our study adds to the current knowledge of genetic susceptibility by demonstrating for the first time an interactive effect between SNPs in IL13 (rs20541) and STAT6 (rs1059513) on the occurrence of eczema in two independent samples. Findings of this report further support the emerging evidence that points toward the existence of genetic effects that occur via complex networks involving gene-gene interactions (epistasis).

Polyunsaturated fatty acid intake and prevalence of eczema and rhinoconjunctivitis in Japanese children: The Ryukyus Child Health Study

PubMed Central

2011-01-01

Background The recent increase in the prevalence of allergic disorders might be a consequence of increased intake of n-6 polyunsaturated fatty acids (PUFAs) and reduced intake of n-3 PUFAs. The current cross-sectional study examined the association between intake levels and the prevalence of eczema and rhinoconjunctivitis in Japanese children. Methods Subjects were 23,388 schoolchildren aged 6-15 years residing in Okinawa. The presence of eczema and/or rhinoconjunctivitis was determined according to the criteria of the International Study of Asthma and Allergies in Childhood. A brief diet history questionnaire for children and adolescents was administered to acquire information on dietary factors. Adjustment was made for age, sex, residential municipality, number of siblings, smoking in the household, body mass index, paternal and maternal history of allergic diseases, and paternal and maternal educational level. Results The prevalences of eczema and rhinoconjunctivitis in the previous 12 months were 7.0% and 8.0%, respectively. Consumption of PUFAs, n-3 PUFAs, α-linolenic acid, n-6 PUFAs, and linoleic acid was positively associated with the prevalence of eczema: the adjusted odds ratios (ORs) between extreme quintiles (95% confidence intervals [CIs], P for trend) were 1.26 (1.07-1.48, 0.04), 1.31 (1.11-1.54, 0.009), 1.31 (1.12-1.55, 0.003), 1.26 (1.07-1.48, 0.01), and 1.27 (1.08-1.49, 0.01), respectively. Arachidonic acid intake was independently inversely related to eczema: the adjusted OR between extreme quintiles was 0.81 (0.69-0.95, 0.0008). Eczema was not associated with eicosapentaenoic or docosahexaenoic acid intake, or with the ratio of n-3 to n-6 PUFA intake. Only arachidonic acid intake was statistically significantly related to the prevalence of rhinoconjunctivitis, showing a clear inverse linear trend: the adjusted OR between extreme quintiles was 0.86 (0.74-0.997, 0.03). Conclusions Consumption of n-3 and n-6 PUFAs, especially α-linolenic acid and linoleic acid, may be positively associated with eczema. Arachidonic acid intake may be inversely related to eczema and rhinoconjunctivitis. PMID:21599987

Background Long-term follow-up was completed in 84 mother-infant pairs of 118 women who completed a randomized controlled trial of prenatal supplementation with EPA- or DHA-rich fish oil or soy oil placebo. The goal of this study was to determine whether prenatal omega-3 fatty acid supplementation protects offspring against development of early childhood allergies. Methods and Findings Assessment of childhood allergic/atopic disease among offspring at age 36 months was performed by maternal interview using the National Health Interview Survey (NHIS) questions for childhood digestive allergies, wheezing, eczema or skin allergy, and respiratory allergy. Multiple logistic regressions examined the association between prenatal supplementation and childhood outcomes, adjusted for covariates. Eczema was reported in 26/84 (31%) of offspring at age 36 months, and was significantly more prevalent in the omega-3 supplementation groups vs. placebo: EPA 13/31 (41.9%); DHA 10/26 (38.5%); placebo 3/27 (11.1%), p=0.019. Compared to placebo, EPA and DHA were associated with ≥5 times risk of offspring eczema [odds ratios (ORs): EPA 5.8 (95% CI 1.4–23.3); DHA 5.0 (95% CI 1.2–21.0)]. After adjusting for other potential risk factors (race, birth weight, vaginal/Cesarean delivery, and maternal eczema) the magnitudes of association for omega-3 supplementation increased: EPA OR 8.1 (95% CI 1.4–45.6); DHA OR 9.6 (95% CI 1.6–58.5). Maternal eczema was also significantly associated with offspring eczema in the adjusted model: OR 10.8 (95% CI 2.1–54.3) Conclusion Contrary to our hypothesis, acids supplementation compared to soy oil was associated with a substantial increase in risk of childhood eczema. This association was not observed on childhood respiratory or digestive outcomes. It is unclear if these findings were driven by unfavorable effects of omega-3s, or whether there may have been unanticipated protective effects of the soy-based placebo with regards to eczema.

We present the case of a 52-year-old woman with a topic dermatitis since adolescence who developed work-related hand eczema, cough and runny nose 12 years after she had started working as a laboratory technician at a precious metals refinery. While skin prick test with sodium hexachloroplatinate (SPTPt ) was negative, patch testing with ammonium tetrachloroplatinate was positive after 24, 48, 72, and 96 hr. Inhalation challenge with sodium hexachloroplatinate yielded cough, mild shortness of breath, and a maximal decrease of FEV1 of 8% from baseline 24 hr after the challenge. Significant increases of bronchial hyperresponsiveness, exhaled nitric monoxide and sputum eosinophils were documented after the challenge. We conclude that eosinophilic airway disease due to platinum salts may occur in SPTPt negative subjects. Both, patch testing and inhalation challenge with platinum salts should be considered in SPT negative subjects with occupational exposure to precious metal salts and work-related allergic symptoms. © 2015 Wiley Periodicals, Inc.

Rhinitis affects many young adults and often shows comorbidity with asthma. We hypothesized that young adult rhinitis, like asthma, exhibits clinical heterogeneity identifiable by means of cluster analysis. Participants in the Isle of Wight birth cohort (n = 1456) were assessed at 1, 2, 4, 10, and 18 years of age. Cluster analysis was performed on those with rhinitis at age 18 years (n = 468) by using 13 variables defining clinical characteristics. Four clusters were identified. Patients in cluster 1 (n = 128 [27.4%]; ie, moderate childhood-onset rhinitis) had high atopy and eczema prevalence and high total IgE levels but low asthma prevalence. They showed the best lung function at 18 years of age, with normal fraction of exhaled nitric oxide (Feno), low bronchial hyperresponsiveness (BHR), and low bronchodilator reversibility (BDR) but high rhinitis symptoms and treatment. Patients in cluster 2 (n = 199 [42.5%]; ie, mild-adolescence-onset female rhinitis) had the lowest prevalence of comorbid atopy, asthma, and eczema. They had normal lung function and low BHR, BDR, Feno values, and total IgE levels plus low rhinitis symptoms, severity, and treatment. Patients in cluster 3 (n = 59 [12.6%]; ie, severe earliest-onset rhinitis with asthma) had the youngest rhinitis onset plus the highest comorbid asthma (of simultaneous onset) and atopy. They showed the most obstructed lung function with high BHR, BDR, and Feno values plus high rhinitis symptoms, severity, and treatment. Patient 4 in cluster 4 (n = 82 [17.5%]; ie, moderate childhood-onset male rhinitis with asthma) had high atopy, intermediate asthma, and low eczema. They had impaired lung function with high Feno values and total IgE levels but intermediate BHR and BDR. They had moderate rhinitis symptoms. Clinically distinctive adolescent rhinitis clusters are apparent with varying sex and asthma associations plus differing rhinitis severity and treatment needs.

Atopic eczema (AE) is a chronic, itchy, inflammatory skin condition that affects the quality of life of children and their families. The role of specialist clothing in the management of AE is poorly understood. To assess the effectiveness and cost-effectiveness of silk garments for the management of AE in children with moderate to severe disease. Parallel-group, observer-blind, randomised controlled trial of 6 months' duration, followed by a 2-month observational period. A nested qualitative study evaluated the beliefs of trial participants, health-care professionals and health-care commissioners about the use of silk garments for AE. Secondary care and the community in five UK centres. Children aged 1-15 years with moderate or severe AE. Participants were randomised (1 : 1 using online randomisation) to standard care or standard care plus 100% silk garments made from antimicrobially protected knitted sericin-free silk [DermaSilk TM (AlPreTec Srl, San Donà di Piave, Italy) or DreamSkin TM (DreamSkin Health Ltd, Hatfield, UK)]. Three sets of garments were supplied per participant, to be worn for up to 6 months (day and night). At 6 months the standard care group received the garments to use for the remaining 2-month observational period. Primary outcome - AE severity using the Eczema Area and Severity Index (EASI) assessed at 2, 4 and 6 months, by nurses blinded to treatment allocation. EASI scores were log-transformed for analysis. Secondary outcomes - patient-reported eczema symptoms (Patient Oriented Eczema Measure); global assessment of severity (Investigator Global Assessment); quality of life of the child (Atopic Dermatitis Quality of Life, Child Health Utility - 9 Dimensions), family (Dermatitis Family Impact Questionnaire) and main carer (EuroQoL-5 Dimensions-3 Levels); use of standard eczema treatments (e.g. emollients, topical corticosteroids); and cost-effectiveness. The acceptability and durability of the clothing, and adherence to wearing the garments, were assessed by parental/carer self-report. Safety outcomes - number of skin infections and hospitalisations for AE. A total of 300 children were randomised (26 November 2013 to 5 May 2015): 42% female, 79% white, mean age 5 years. The primary analysis included 282 out of 300 (94%) children ( n  = 141 in each group). Garments were worn for at least 50% of the time by 82% of participants. Geometric mean EASI scores at baseline, 2, 4 and 6 months were 8.4, 6.6, 6.0, 5.4 for standard care and 9.2, 6.4, 5.8, 5.4 for silk clothing, respectively. There was no evidence of difference between the groups in EASI score averaged over all follow-up visits adjusted for baseline EASI score, age and centre (ratio of geometric means 0.95, 95% confidence interval 0.85 to 1.07; p  = 0.43). This confidence interval is equivalent to a difference of -1.5 to 0.5 in the original EASI scale units. Skin infections occurred in 39 out of 141 (28%) and 36 out of 142 (25%) participants for standard care and silk clothing groups, respectively. The incremental cost per QALY of silk garments for children with moderate to severe eczema was £56,811 from a NHS perspective in the base case. Sensitivity analyses supported the finding that silk garments do not appear to be cost-effective within currently accepted thresholds. Knowledge of treatment allocation may have affected behaviour and outcome reporting for some of the patient-reported outcomes. The addition of silk garments to standard AE care is unlikely to improve AE severity, or to be cost-effective compared with standard care alone, for children with moderate or severe AE. This trial adds to the evidence base to guide clinical decision-making. Non-pharmacological interventions for the management of AE remain a research priority among patients.

A lack of information about disease in children can lead to erroneous views such as children believing that hospital admittance or the presence of a disease is a punishment for a perceived wrong. There has thus far been no standard tool available to measure children's illness conceptualizations from a Leventhalian framework. Three groups of children with eczema, asthma and eczema and asthma between the ages of 7 and 12 years of age were recruited. Children were given the Children's Illness Perception Questionnaire (CIPQ), a 26-item instrument adapted from the Illness Perception Questionnaire for adults. A Kuder - Richardson 20 test of reliability for dichotomous data was performed allowing an estimate of the internal consistency of the measurement scales. It can be seen that, for all three illness groups, internal consistency is acceptable for the timeline and consequences scale. The cure/control scale, however, was not internally consistent for any illness group. As health professionals, we need to develop the means to further understand how paediatric illness beliefs relate to specific disease types, age and psychosocial factors and the utility of this instrument is discussed within this context.

Managing atopic eczema in childhood: the health visitor and school nurse role.

2008-06-01

Atopic eczema affects up to 20% of children in the UK. It is a disease of varying severity, and health visitors and school nurses have a vital role in educating and supporting children and their parents and carers in its management. Diagnosis and assessment needs to consider atopic eczema severity, effect on quality of life and contributing trigger factors. Treatment should be tailored to the individual child and should include education on emollient therapy, the use of topical corticosteroids and other measures. A case study is included to highlight practical issues and the support of the child and family in coping with atopic eczema at home and in school.

Eczema in early life: Genetics, the skin barrier, and lessons learned from birth cohort studies

Biagini Myers, Jocelyn M.; Khurana Hershey, Gurjit K.

2010-01-01

Eczema is a chronic inflammatory disorder of the skin that affects up to 30% of children. It often afflicts infants in the first few months of life and can be the first indicator of the atopic march. Recent results from birth cohort studies have uncovered novel information regarding genetic and environmental factors that promote the development of eczema. Birth cohort studies provide an optimal study design to elucidate these associations and prospectively track longitudinal data including exposure assessment and health outcomes from birth into early life and childhood. This is especially relevant for eczema given the age specific emergence of this disease. In this review, we will provide a general overview of pediatric eczema and discuss the important findings in the literature with respect to genetics and environmental exposures, highlighting those derived from birth cohort studies. Additionally, we will review how these relate to the atopic march, the hygiene hypothesis and the integrity of the skin barrier. PMID:20739029

Experimental eczema. 12 effects of x-rays in experimental eczema (combined injury) (in French)

Contact dermatitis was induced in guinea pig nipples by local application of 2,4-dinitrochlorobenzene after previous sensitization. No effect of x irradiation on the histologic aspects of the developing dermatitis could be detected when doses of 800 or 1600 r were given 2 to 16 days after sensitization or repeated 100-r doses were given. Although a 800-r dose had no detectable effect on epithelium, it was found to alter the eczematous reaction when given 72 hr before the eliciting application of dinitrocitlorobenzene in sensitized animals. Eczematous epithelium in irradiated skin showed swelling of cells, indistinct cell boundaries, diminished numbers of nuclei,more » and fewer mitoses blocked by colchicine; none of these changes was produced by eczema alone. The changes in epidermis induced by irradiation with 800 r before eliciting eczema resembled those produced by much higher x-ray doses (2400 r), indicating that eczema augments the cellular changes induced by irradiation.« less

Eczema often precedes the development of asthma in a disease course called the ‘atopic march'. To unravel the genes underlying this characteristic pattern of allergic disease, we conduct a multi-stage genome-wide association study on infantile eczema followed by childhood asthma in 12 populations including 2,428 cases and 17,034 controls. Here we report two novel loci specific for the combined eczema plus asthma phenotype, which are associated with allergic disease for the first time; rs9357733 located in EFHC1 on chromosome 6p12.3 (OR 1.27; P=2.1 × 10−8) and rs993226 between TMTC2 and SLC6A15 on chromosome 12q21.3 (OR 1.58; P=5.3 × 10−9). Additional susceptibility loci identified at genome-wide significance are FLG (1q21.3), IL4/KIF3A (5q31.1), AP5B1/OVOL1 (11q13.1), C11orf30/LRRC32 (11q13.5) and IKZF3 (17q21). We show that predominantly eczema loci increase the risk for the atopic march. Our findings suggest that eczema may play an important role in the development of asthma after eczema. PMID:26542096

The psychological impact of childhood atopic eczema on parents and carers is poorly quantified. Objectives To compare the impact of caring for a child with atopic eczema vs. asthma on parents' sleep and well-being. Ninety-two parents of 55 children who had moderate to severe atopic eczema or asthma took part in this prospective, questionnaire-based study. It was conducted at regional eczema and asthma outpatient clinics within a U.K. tertiary paediatric hospital. The main outcome measures were the number and duration of parents' sleep disturbances, as well as their anxiety and depression scores. Mothers caring for children with atopic eczema lost a median of 39 min of sleep per night and fathers lost 45 min sleep per night. This compared with a median of 0 min sleep lost by parents who had children with asthma (P < 0.001). These differences were independent of the age of the children, and whether the child came from a single-parent or two-parent family. There was a direct correlation between the severity of sleep disturbance and the level of maternal anxiety (rho = 0.58; P = 0.002) and depression (rho = 0.73; P < 0.001), as well as the level of paternal anxiety (rho = 0.59; P = 0.01). Compared with looking after a child with chronic asthma, caring for a child with chronic atopic eczema was associated with greater parental sleep disturbances. Disruption to parental sleep correlated with anxiety levels and, in the case of mothers, depression scores.

Gut microbiota play an important role in human immunological processes, potentially affecting allergic diseases such as eczema. The diversity and structure of gut microbiota in infants with eczema have been previously documented. This study aims to evaluate by comparative metagenomics differences in genetic content in gut microbiota of infants with eczema and their matched controls. Stools were collected at the age of one month old from twelve infants from an at risk birth cohort in a case control manner. Clinical follow up for atopic outcomes were carried out at the age of 12 and 24 months. Microbial genomic DNA were extracted from stool samples and used for shotgun sequencing. Comparative metagenomic analysis showed that immune-regulatory TCAAGCTTGA motifs were significantly enriched in the six healthy controls (C) communities compared to the six eczema subjects (E), with many encoded by Bifidobacterium (38% of the total motifs in the C communities). Draft genomes of five Bifidobacterium species populations (B. longum, B. bifidum, B. breve, B. dentium, and B. pseudocatenulatum) were recovered from metagenomic datasets. The B. longum BFN-121-2 genome encoded more TCAAGCTTGA motifs (4.2 copies per one million genome sequence) than other Bifidobacterium genomes. Additionally, the communities in the stool of controls (C) were also significantly enriched in functions associated with tetrapyrrole biosynthesis compared to those of eczema (E). Our results show distinct immune-modulatory genomic properties of gut microbiota in infants associated with eczema and provide new insights into potential role of gut microbiota in affecting human immune homeostasis.

Although alcohol consumption has been suggested to have an effect on the immune system, it is unknown whether alcohol consumption has a role in developing allergic diseases. We aimed to examine the associations of total alcohol intake during pregnancy with the risks of childhood asthma and atopic eczema in a birth cohort in Japan. Pregnant women were recruited at a maternal clinic from May 2000 to October 2001. The children who were born to these mothers were followed until November 2007. Total alcohol intake, including alcohol as a cooking ingredient, was assessed using 5-day dietary records. Mother reports of physician-diagnosed asthma and atopic eczema were annually obtained from the questionnaires. Asthma assessed by the American Thoracic Society Division of Lung Diseases questionnaire and atopic eczema assessed by International Study of Asthma and Allergies in Childhood questions were also obtained in 2007. A total of 350 children participated in the follow-up survey. Maternal total alcohol intake during pregnancy was associated with increased risks of atopic eczema before age 3. The positive association with atopic eczema was also observed when it was defined as before age 5. In the high versus the low tertile of maternal total alcohol intake, the estimated hazard ratios (HRs) of child's eczema were 1.90 (95% CI: 0.96 to 3.76) before age 3 and 1.74 (95% CI: 0.93 to 3.24) before age 5, respectively. The estimated HRs of child's asthma before age 3 was 1.61 (95% CI: 0.70 to 3.69) in the high versus the low of maternal total alcohol intake and 2.11 (95% CI: 0.93 to 4.81) among children having drinking mothers versus nondrinking mothers in pregnancy, although maternal alcohol intake during pregnancy was not significantly associated with the risk of asthma before age 5. Alcohol consumption during pregnancy might have an effect on developing atopic eczema in offspring. Copyright © 2016 by the Research Society on Alcoholism.

Introduction Chronic disease is a barrier to delivery of preventive health care and health maintenance. However, health behaviors of adults and children with eczema, a chronic skin disorder, have not been examined. This study examined associations of eczema with vaccination, disease screening, health maintenance, and healthcare utilization. Methods This study investigated 34,613 adults and 13,298 children from the 2012 National Health Interview Survey, a prospective questionnaire-based study. Data were analyzed between August 2014 and January 2015. Results Adult eczema was associated with higher odds of vaccination for tetanus (OR [95% CI]= 1.37 [1.22, 1.54]); influenza (1.23 [1.10, 1.37]); hepatitis A (1.21 [1.04, 1.41]) and B (1.21 [1.07, 1.35]); human papilloma virus (1.66 [1.32, 2.08]); and pneumonia (1.35 [1.19, 1.54]), but not herpes zoster virus (1.07 [0.87, 1.31]). Adult eczema was associated with increased measurement of blood glucose (1.29 [1.16, 1.44]); cholesterol (1.19 [1.06, 1.34]); blood pressure (1.84 [1.56, 2.08]); and HIV infection (1.50 [1.34, 1.70]), but not Pap smears (1.11 [0.95, 1.30]); colon cancer screening (p=0.17); or mammograms (p=0.63). Adults with eczema were more likely to interact with general doctors, mid-level providers, mental health professionals, eye doctors, podiatrists, chiropractors, therapists, obstetrician/gynecologists, and other specialists (p≤0.01). Childhood eczema was associated with higher rates of vaccination for influenza (p<0.0002); well child checkups (p=0.002); and interaction with most types of healthcare providers (p≤0.01). Many associations remained significant in multivariate models controlling for sociodemographics and healthcare interaction frequency. Conclusions Eczema in adults and children is associated with greater utilization of preventive health care and health maintenance, but not cancer screening. PMID:26547540

We recently demonstrated a dual effect of breastfeeding with increased risk of eczema and decreased risk of wheezing in early childhood by increasing breastfeeding length. We hypothesize that immune mediators in breast milk could explain such association either through a direct effect or as a surrogate marker of maternal immune constitution. To investigate the possible association between cytokine and chemokine levels in breast milk and development of eczema and recurrent wheeze during early childhood. Levels of 19 pro-inflammatory and immunoregulatory cytokines and chemokines were measured in 223 breast milk samples from mothers in the Copenhagen Prospective Study on Asthma in Childhood2000 (COPSAC) high-risk birth cohort. Eczema and recurrent wheeze at the age of 0-3 years were prospectively diagnosed by COPSAC physicians adherent to predefined validated algorithms. Association analyses were performed by Cox regression adjusting for potential confounding factors and by multivariable principal component analysis. Increased IL-1β in breast milk (≥ 0.7 pg/mL) was associated with more than a halved risk of eczema before age three (aHR = 0.41; 95% CI = 0.24-0.68; P < 0.001), which remained significant after false discovery rate adjustment (P = 0.008). The principal component analysis confirmed that a mediator pattern dominated by high levels of IL-1β, IL-17A, and CCL17 and low levels of CXCL1 and TSLP in breast milk protected against eczema (aHR = 0.82; 95% CI = 0.68-0.98; P = 0.03). No associations were observed for recurrent wheeze. Elevated breast milk IL-1β level was associated with decreased risk of early childhood eczema suggesting either a direct protective effect of IL-1β or IL-1b acting as a proxy for a healthy maternal immune system protecting high-risk offspring from eczema. © 2016 John Wiley & Sons Ltd.

The extravasation of T cells at sites of inflammation is critically dependent on the activity of homing receptors (HR) involved in endothelial cell recognition and binding. Two such HR (the cutaneous lymphocyte antigen [CLA] and L-selectin) have been shown to be selectively involved in T cell migration to skin and peripheral lymph nodes, respectively. This study was designed to assess the relationship between the organ specificity of an allergic reaction to food and the expression of HR on T cells activated in vitro by the relevant food allergen. Peripheral blood mononuclear cells were isolated from seven milk allergic children with a history of eczema when exposed to milk. All patients had a positive prick skin test and double-blind placebo-controlled food challenge to milk. 10 children with either allergic eosinophilic gastroenteritis or milk-induced enterocolitis and 8 nonatopic adults served as controls. Five-parameter flow cytometry using monoclonal antibodies was used for detection of the specific HR on freshly isolated T cells versus T cell blasts induced by a 6-d incubation with casein, as compared with Candida albicans. After in vitro stimulation with casein, but not C. albicans, patients with milk allergy and atopic dermatitis had a significantly greater percentage of CLA+ T cells (P < 0.01) than controls with milk-induced enterocolitis, allergic eosinophilic gastroenteritis, or nonatopic healthy controls. In contrast, the percentage of L-selectin-expressing T cells did not differ significantly between these groups. These data suggest that after casein stimulation allergic patients with milk-induced skin disease have an expanded population of CLA+ T cells, as compared with nonatopics or allergic patients without skin involvement. We postulate that heterogeneity in the regulation of HR expression on antigen-specific T cells may play a role in determining sites of involvement in tissue-directed allergic responses.

Sensitization to common allergens and its association with allergic disorders at age 4 years: a whole population birth cohort study.

Atopy is defined as the genetic propensity to develop immunoglobulin E antibodies in response to exposure to allergens and assessed by skin prick test responses to common allergens. Although it is generally agreed that atopy is an important risk factor for allergic diseases such as asthma, rhinitis, and eczema, the extent to which atopy accounts for these diseases is controversial. We aim to describe the prevalence of sensitization to common allergens and investigate the degree of association of atopy (as defined by positive skin prick test to 1 or more common allergens) to asthma, rhinitis, and eczema in a birth cohort at the age of 4 years. A birth cohort of 1456 children was recruited over a 14-month period (1989-1990). These children have been seen previously at 1 and 2 years of age. At 4 years, 1218 children were reviewed and an interview was administered or postal questionnaire was completed for the presence of allergic diseases (asthma, rhinitis, and eczema). Additionally, in 981 children, skin prick tests with a battery of 12 common allergens were performed. Allergens were house dust mite (Dermatophagoides pteronyssimus), grass pollen mix, cat, dog, Alternaria alternata, Cladosporium herbarum, cow's milk, hen's egg, soya, cod, wheat, and peanut. A mean wheal diameter of at least 3 mm greater than the negative control was taken as positive. This analysis is confined to the 981 (67% of the original population) who also had skin prick tests to the standard battery. chi(2) tests were used to test the univariate association between each allergic disease and positive skin test. Multiple logistic regression analysis was performed to obtain the adjusted odds ratios (ORs) and 95% confidence intervals (CIs) for the independent effect of sensitization to each allergen on allergic disease, adjusting for the effect of sensitization to other allergens. To ascertain how much of allergic disease is attributable to atopy, we estimated the population-attributable risk. This was calculated with the formula: P(R - 1) where R is the OR for the allergic disease under consideration and P is the proportion of atopy in children with that disease. Children who were skin prick-tested at 4 years were similar in most characteristics to the rest of the population, except that they had a higher prevalence of allergic disease. Allergic disorders (asthma, rhinitis, and eczema) were present in 276 (28.1%) of 981. One hundred ninety-two (19.6%) children were atopic (positive reaction to 1 or more allergens). Sensitization to inhalant allergens was relatively common (19.2%) as compared with food allergens (3.5%). House dust mite (11.9%), grass pollen (7.8%), and cat (5.8%) were the most common positive reactions. A test to the 4 most common allergens (house dust mite, grass pollen, cat, and A alternata) could detect 94% of the atopic children. Sensitization to the 4 most common allergens was strongly associated with the presence of allergic disorders. There was a graded effect with the potent allergens, such as house dust mite, having the greatest impact. For example, 50% of children sensitized to house dust mite had asthma as opposed to 44% sensitized to cat, 42% sensitized to grass pollen, and 32% sensitized to A alternata. Overall, 68.4% of children sensitized to house dust mite had asthma, eczema, and/or rhinitis. The respective figures for grass pollen, cat, and A alternata were 64.9%, 66.7%, and 57.4%. The proportion of children sensitized to cat was not higher in households with cat ownership (households with cats: 5.1% [19/374]; households without cats: 6.2% [36/580]; not significant [NS]). Similarly, no difference was seen in sensitization to dog in households with and without dogs (households with dogs: 1.8% [5/282]; households without dogs: 2.8% [19/673]; NS). Boys were atopic more often than girls at this age (male: 112 of 497 [22.5%] vs female: 80 of 484 [16.5%]; OR: 1.47, 95% CI: 1.07-2.02). Male preponderance was observed with most allergens, but this was statistically significant only for house dust mite (male: 75/497 [15.1%] vs female: 42/484 [8.7%]; OR: 1.87; CI: 1.25-2.79) and grass pollen (male: 51/497 [10.3%] vs female: 26/484 [5.4%]; OR: 2.01; CI: 1.23-3.29). An independent effect of allergen sensitization on asthma was observed only with house dust mite with an OR of 8.07 (CI: 4.60-14.14). The highest independent risk for rhinitis was sensitization to grass pollen (OR: 5.02; CI: 2.21-11.41), and for eczema, sensitization to peanut (OR: 4.65; CI: 1.02-21.34). The majority of children (98/192) were sensitized to >1 allergen. A graded effect was observed with the risk of allergic disease in the child increasing with the number of positive skin prick test reactions. This effect was consistent throughout the spectrum of allergic diseases (asthma, eczema, and rhinitis). (ABSTRACT TRUNCATED)

Atopic dermatitis (AD) is a common chronic inflammatory skin disease. Malassezia, the predominant skin microbiota fungus, is considered to exacerbate AD, especially in a subset of patients with head and neck type AD (HNAD). In the present study, the relationship between AD and sensitization to Malassezia antigens was investigated. We assessed 173 patients with AD. The severity of eczema was determined with Eczema Area and Severity Index (EASI); the type of AD, namely, head and neck type, was reported as well. The total serum IgE and specific IgE to Malassezia were determined and correlated with clinical picture of AD, sex, age, and the EASI. Total IgE was elevated in 77.7% of patients. Specific IgE to Malassezia was positive (≥0.35 kU/L) in 49.1% of patients. Men were significantly more often sensitized to Malassezia antigen (58% of men vs 42% of women; P value, 0.04). Concurrently, 58% of patients with HNAD versus 42% non-HNAD patients had higher levels of specific IgE to Malassezia, this difference being nearly significant (P value, 0.06). Patients with atopy were also more frequently sensitized to Malassezia. No significant relationship between EASI and the level of total IgE or specific IgE to Malassezia was observed. In our population, IgE-mediated sensitization was found in up to 49% of all patients with AD, most common in men and in head and neck type.

Quality of life and childhood atopic dermatitis: the misery of living with childhood eczema.

PubMed

Lewis-Jones, S

2006-08-01

The misery of living with atopic eczema (syn. dermatitis, AD) cannot be overstated for it may have a profoundly negative effect on the health-related quality of life (HRQoL) of children and their family unit in many cases. As it is one of the commonest chronic relapsing childhood dermatosis (UK lifetime prevalence 16-20% by 20 years), with increasing worldwide prevalence, this has major social and financial implications for individuals, healthcare providers and society as a whole. This review explores the impact of AD on the lives of children and their family units and the use of some of the recently developed HRQoL measures, which have enabled investigation and categorisation of the physical, psychological and psycho-social effects of childhood eczema across all aspects of life. These effects include symptoms of itching and soreness, which cause sleeplessness in over 60%. Sleep deprivation leads to tiredness, mood changes and impaired psychosocial functioning of the child and family, particularly at school and work. Embarrassment, comments, teasing and bullying frequently cause social isolation and may lead to depression or school avoidance. The child's lifestyle is often limited, particularly in respect to clothing, holidays, staying with friends, owning pets, swimming or the ability to play or do sports. Restriction of normal family life, difficulties with complicated treatment regimes and increased work in caring for a child with eczema lead to parental exhaustion and feelings of hopelessness, guilt, anger and depression. The hidden costs involved in eczema management can be significant and have particular impact on lower income families. The impairment of quality of life caused by childhood eczema has been shown to be greater than or equal to other common childhood diseases such as asthma and diabetes, emphasising the importance of eczema as a major chronic childhood disease. HRQoL measures are proving to be valuable tools for use in the clinical setting, as outcome measures for pharmaceutical studies, for health economics and audit purposes. It is therefore recommended that in future, they should be used in conjunction with objective measures of severity, as part of the assessment process of a child with atopic eczema. Lack of information on eczema and treatments heightens parental anxiety. Education of all individuals involved in the care of children with eczema is fundamental in the management of AD and it is essential to provide simple clear, unambiguous information on treatment and disease management in order to reduce the negative impact on HRQoL.

"To screen or not to screen": Comparing the health and economic benefits of early peanut introduction strategies in five countries.

Early peanut introduction (EPI) in the first year of life is associated with reduced risk of developing peanut allergy in children with either severe eczema and/or egg allergy. However, EPI recommendations differ among countries with formal guidelines. Using simulation and Markov modeling over a 20-year horizon to attempt to explore optimal EPI strategies applied to the US population, we compared high-risk infant-specific IgE peanut screening (US/Canadian) with the Australiasian Society for Clinical Immunology and Allergy (Australia/New Zealand) (ASCIA) and the United Kingdom Department of Health (UKDOH)-published EPI approaches. Screening peanut skin testing of all children with early-onset eczema and/or egg allergy before in-office peanut introduction was dominated by a no screening approach, in terms of number of cases of peanut allergy prevented, quality-adjusted life years (QALY), and healthcare costs, although screening resulted in a slightly lower rate of allergic reactions to peanut per patient in high-risk children. Considering costs of peanut allergy in high-risk children, the per-patient cost of early introduction without screening over the model horizon was $6556.69 (95%CI, $6512.76-$6600.62), compared with a cost of $7576.32 (95%CI, $7531.38-$7621.26) for skin test screening prior to introduction. From a US societal perspective, screening prior to introduction cost $654 115 322 and resulted in 3208 additional peanut allergy diagnoses. Both screening and nonscreening approaches dominated deliberately delayed peanut introduction. A no-screening approach for EPI has superior health and economic benefits in terms of number of peanut allergy cases prevented, QALY, and total healthcare costs compared to screening and in-office peanut introduction. © 2018 EAACI and John Wiley and Sons A/S.

Core outcome sets (COSs) are consensus-derived minimum sets of outcomes to be assessed in a specific situation. COSs are being increasingly developed to limit outcome-reporting bias, allow comparisons across trials, and strengthen clinical decision making. Despite the increasing interest in outcomes research, methods to develop COSs have not yet been standardized. The aim of this paper is to present the Harmonizing Outcomes Measures for Eczema (HOME) roadmap for the development and implementation of COSs, which was developed on the basis of our experience in the standardization of outcome measurements for atopic eczema. Following the establishment of a panel representing all relevant stakeholders and a research team experienced in outcomes research, the scope and setting of the core set should be defined. The next steps are the definition of a core set of outcome domains such as symptoms or quality of life, followed by the identification or development and validation of appropriate outcome measurement instruments to measure these core domains. Finally, the consented COS needs to be disseminated, implemented, and reviewed. We believe that the HOME roadmap is a useful methodological framework to develop COSs in dermatology, with the ultimate goal of better decision making and promoting patient-centered health care.

Professional photosensitive eczema of fishermen by contact with bryozoans: disabling occupational dermatosis.

2008-01-01

Eczema associated with bryozoans is a form of occupational dermatosis caused by a living animal, involving contact eczema, occasionally associated with photosensitivity and concerning fishermen on a quasi-elective basis. This affection can prove to be extremely disabling, frequently generating disastrous social consequences, since the eviction of the responsible allergen is very often synonymous to occupational reclassification, a measure which fishermen, highly attached to their profession, have great difficulty in accepting. Based on the description of three cases of photosensitive eczema associated with contact with the bryozoan, Alcyonidium gelatinosum, identified in fishermen from the English Channel coastline, we describe the characteristics and the specificities of this occupational dermatosis, then approach the issue of its prevention, which, unfortunately, remains limited.

Nickel levels in urine were determined among 163 female dermatological patients aged 18 to 46 years. Data on life-style factors were collected in parallel via a questionnaire. Urinary nickel excretion was in the normal range of the German female population (0.2-46.1 microg Ni/g creatinine). The 95th percentile (3.9 microg Ni/l urine) exceeded the German reference value (3.0 microg Ni/l urine). In the multivariate regression analyses we found a statistically significant increase of ln-transformed nickel levels with increase in age and in women using dietary supplements. The following variables were not associated with Nickel urine levels: suffering from nickel eczema, smoking, drinking stagnated water, eating foods with high nickel contents and using nickel-containing kitchen utensils as, for example, an electric kettle with an open heater coil. We conclude that personal urinary levels should be assessed with simultaneous consideration of habits and life-style factors. A German national survery would be useful. Those patients who experience the exacerbation of their eczema in cases of oral provocation, for example, by a high nickel diet should be aware of potential sources of nickel, such as supplements.

The capsaicin cough reflex in eczema patients with respiratory symptoms elicited by perfume.

2006-03-01

Respiratory symptoms elicited by perfume are common in the population but have unclear pathophysiology. Increased capsaicin cough responsiveness has been associated with the symptoms, but it is unknown whether the site of the symptoms in the airways influences this association. The aim of this study was to investigate the association between the site of airway symptoms elicited by perfume and cough responsiveness to bronchial challenge with capsaicin. 21 eczema patients with respiratory symptoms elicited by perfume were compared with 21 healthy volunteers in a sex- and age-matched case control study. The participants completed a symptom questionnaire and underwent a bronchial challenge with capsaicin. Lower, but not upper, respiratory symptoms elicited by perfume were associated with increased capsaicin cough responsiveness. Having severe symptoms to perfume (n=11) did not relate to the site of the symptoms in the airways and was not associated with increased capsaicin cough responsiveness. In conclusion, respiratory symptoms elicited by perfume may reflect local hyperreactivity related to defensive reflexes in the airways, and measurements of the capsaicin cough reflex are relevant when patients with lower respiratory symptoms related to environmental perfume exposures are investigated.

Clinical verification in homeopathy and allergic conditions.

PubMed

Van Wassenhoven, Michel

2013-01-01

The literature on clinical research in allergic conditions treated with homeopathy includes a meta-analysis of randomised controlled trials (RCT) for hay fever with positive conclusions and two positive RCTs in asthma. Cohort surveys using validated Quality of Life questionnaires have shown improvement in asthma in children, general allergic conditions and skin diseases. Economic surveys have shown positive results in eczema, allergy, seasonal allergic rhinitis, asthma, food allergy and chronic allergic rhinitis. This paper reports clinical verification of homeopathic symptoms in all patients and especially in various allergic conditions in my own primary care practice. For preventive treatments in hay fever patients, Arsenicum album was the most effective homeopathic medicine followed by Nux vomica, Pulsatilla pratensis, Gelsemium, Sarsaparilla, Silicea and Natrum muriaticum. For asthma patients, Arsenicum iodatum appeared most effective, followed by Lachesis, Calcarea arsenicosa, Carbo vegetabilis and Silicea. For eczema and urticaria, Mezereum was most effective, followed by Lycopodium, Sepia, Arsenicum iodatum, Calcarea carbonica and Psorinum. The choice of homeopathic medicine depends on the presence of other associated symptoms and 'constitutional' features. Repertories should be updated by including results of such clinical verifications of homeopathic prescribing symptoms. Copyright © 2012 The Faculty of Homeopathy. Published by Elsevier Ltd.

Recommendations for interpretation of skin prick test to foods in atopic eczema, management of allergic conjunctivitis, hypertension and breastfeeding in women treated with antiepileptic drugs and healthy breakfast have been reported. Epidemiological studies have given emphasis to high incidence of autoimmune disorders in patients with Turner syndrome, increasing prevalence of celiac disease, frequency of hypertension in adolescents, incidence and risk factor for retinopathy of prematurity. Advances in prevention include elucidation of the role of probiotics in reducing occurrence of allergies and feeding intolerance, and events of foetal life that influence later onset of diseases. Mechanistic studies suggested a role for vitamin D deficiency in asthma and type 1 diabetes and for reactivation of Varicella-Zoster virus in aseptic meningitis. Regarding diagnosis, a new mean for the diagnosis of hyperbilirubinaemia in newborns, a score for recognition of impaired nutritional status and growth and criteria for early Dyke-Davidoff-Masson Syndrome have been suggested. New therapeutic approaches consist of use of etanercept for reducing insulin dose in type 1 diabetes, probiotics in atopic eczema, and melatonin in viral infections.

Mechanistic studies suggested a role for vitamin D deficiency in asthma and type 1 diabetes and for reactivation of Varicella-Zoster virus in aseptic meningitis. Regarding diagnosis, a new mean for the diagnosis of hyperbilirubinaemia in newborns, a score for recognition of impaired nutritional status and growth and criteria for early Dyke-Davidoff-Masson Syndrome have been suggested. New therapeutic approaches consist of use of etanercept for reducing insulin dose in type 1 diabetes, probiotics in atopic eczema, and melatonin in viral infections. PMID:25015124

The common manifestations of atopic dermatitis (AD) appear sequentially with involvement of the cheeks in infancy, flexural extremities in childhood, and hands in adulthood. Although less common clinical manifestations are well described, they have not been the subject of epidemiologic studies to describe their prevalence in specific age groups. This observational, cross-sectional, comparative study included 131 children younger than 18 of both sexes with AD who attended the clinics of the Dermatology Department of the National Institute of Pediatrics in Mexico City. Patients were examined to determine the presence of infrequent clinical manifestations of AD during infancy, preschool and school age, and adolescence and stratified according to sex, age, and number of clinical signs. A chi-square test was used to detect differences according to age and sex. Logistic regression analysis was also performed. The main findings according to age were genital dermatitis and papular-lichenoid dermatitis variant in infants; atopic feet, prurigo-like, nummular pattern, and erythroderma in preschool and school-aged children; and eyelid eczema and nipple dermatitis in adolescents. The risk of development of nipple dermatitis and eyelid eczema increased with age, and the development of genital dermatitis decreased with age. The knowledge of the prevalence of less common clinical manifestations of AD according to age in different populations might be helpful in diagnosing incipient cases of AD. © 2012 Wiley Periodicals, Inc.

Tinea incognito (TI) is a dermatophytic infection which has lost its typical clinical appearance because of improper use of steroids or calcineurin inhibitors. The incidence of TI is increasing nowadays. We conducted retrospective review on 283 patients with TI from 25 dermatology training hospitals in Korea from 2002-2010 to investigate the demographical, clinical, and mycological characteristics of TI, and to determine the associated risk factors. More than half (59.3%) patients were previously treated by non-dermatologists or self-treated. The mean duration of TI was 15.0 ± 25.3 months. The most common clinical manifestations were eczema-like lesion, psoriasis-like, and lupus erythematosus-like lesion. The trunk and face were frequently involved, and 91 patients (32.2%) also had coexisting fungal infections. Among 67 isolated strains, Trichophyton rubrum was the most frequently detected (73.1%). This is the largest study of TI reported to date and the first investigational report concerning TI in Korea. We suggest that doctors should consider TI when a patient has intractable eczema-like lesions accompanied by tinea pedis/unguium. Furthermore, there should be a policy change, which would make over-the-counter high-potency topical steroids less accessible in some countries, including Korea. PMID:23341725

Although most patients with atopic dermatitis (AD) are effectively managed with topical medication, a significant minority require systemic therapy. Guidelines for decision making about advancement to systemic therapy are lacking. To guide those considering use of systemic therapy in AD and provide a framework for evaluation before making this therapeutic decision with the patient. A subgroup of the International Eczema Council determined aspects to consider before prescribing systemic therapy. Topics were assigned to expert reviewers who performed a topic-specific literature review, referred to guidelines when available, and provided interpretation and expert opinion. We recommend a systematic and holistic approach to assess patients with severe signs and symptoms of AD and impact on quality of life before systemic therapy. Steps taken before commencing systemic therapy include considering alternate or concomitant diagnoses, avoiding trigger factors, optimizing topical therapy, ensuring adequate patient/caregiver education, treating coexistent infection, assessing the impact on quality of life, and considering phototherapy. Our work is a consensus statement, not a systematic review. The decision to start systemic medication should include assessment of severity and quality of life while considering the individual's general health status, psychologic needs, and personal attitudes toward systemic therapies.

The ideal nomenclature of atopic dermatitis (AD) / atopic eczema (AE) has long been contested. However, it is becoming increasingly clear that the disparate nomenclature of this disease may have important deleterious ramifications for clinical care and research. An electronic questionnaire regarding the preferred nomenclature for AD was sent to councilors of the International Eczema Council (IEC) (n=77), an international group of clinicians and researchers with expertise in AD/AE. The survey consisted of 2 questions for consensus regarding the preference for an atopic prefix, and preference for the term AD or AE, and an exploratory question about the acceptability of the terms AD, AE or eczema. Consensus was defined a priori as at least 90% agreement for each question with a response rate of at least 90%. Seventy-one of 77 (92.2%) IEC councilors and associates responded to the survey, with all respondents completing the entire survey. Consensus was reached for question 1, with 69 of 71 respondents (97.2%) preferring the atopic prefix. However, consensus was not reached for question 2, with 40 respondents (58.0%) preferring the term AD and 30 (43,5%) preferring AE. Sixty-three respondents (88.7%) and 55 (77.5%) felt that the terms AD and AE were acceptable, whereas only 11 (15.5%) felt that eczema was acceptable. The IEC noted that the term eczema is imprecise, and its use is confusing. The consensus of the IEC was to recommend use of the prefix "atopic" (i.e., AD or AE) in all publications, presentations and discussions about the disorder. © 2017 EAACI and John Wiley and Sons A/S.

One factor capable of modulating antenatal immune responses is diet. This prospective study examined the association between maternal intake of specific types of fatty acids, cholesterol, fish and meat during pregnancy and the risk of wheeze and eczema in the offspring. Subjects were 763 mother-child pairs. Data on maternal intake during pregnancy were assessed with a diet history questionnaire. Data on wheeze and eczema based on criteria of the International Study of Asthma and Allergies in Childhood were obtained from a questionnaire completed by mothers 16-24 months postpartum. Higher maternal intake of alpha-linolenic acid and docosahexaenoic acid during pregnancy was independently associated with a reduced risk of wheeze, but not eczema, in the offspring (adjusted odds ratios (ORs) between extreme quartiles 0.52 (95% CI 0.28 to 0.97) and 0.37 (95% CI 0.15 to 0.91), respectively). Higher maternal intake of n-6 polyunsaturated fatty acids and linoleic acid during pregnancy was independently related to an increased risk of infantile eczema but not wheeze (adjusted ORs 2.25 (95% CI 1.13 to 4.54) and 2.11 (95% CI 1.06 to 4.26), respectively). No significant exposure-response relationships were observed between maternal consumption of total fat, saturated fatty acids, monounsaturated fatty acids, eicosapentaenoic acid, arachidonic acid, cholesterol, meat and fish and the ratio of n-3 to n-6 polyunsaturated fatty acid consumption during pregnancy and infantile wheeze or eczema. Maternal intake of alpha-linolenic acid and docosahexaenoic acid during pregnancy may be preventive against infantile wheeze. Maternal intake of n-6 polyunsaturated fatty acids, especially linoleic acid, during pregnancy may increase the risk of childhood eczema.

Physiological and pathological skin eruptions are commonly encountered in neonates in our clinical practice. However, the types of skin eruptions that are associated with the subsequent development of atopic dermatitis and the mechanisms of these associations remain uncertain. A total of 105 newborn babies with normal delivery were enrolled in this prospective cohort study. The cord blood eosinophil count was measured and the neonates were examined at 1 month of age and followed until 8 years of age. At 1 month of age, infantile eczema, seborrheic dermatitis, intertrigo and diaper dermatitis were diagnosed in a total of 29, 7, 14 and 24 neonates, respectively. No association was found among the prevalences of these eruptions. Neonates with infantile eczema had a significantly higher number and ratio of eosinophils in the cord blood (eosinophil count: 670.8 +/- 67.8 vs. 349.0 +/- 30.3/microl, p < 0.0001; eosinophil ratio: 5.12 +/- 0.53 vs. 2.61 +/- 0.22%, p < 0.0001, for the presence and the absence of infantile eczema, respectively). In contrast, no such tendency was found for any other skin eruptions. In neonates with infantile eczema at 1 month of age, the diagnosis of atopic dermatitis had been made significantly earlier and the prevalence of wheezing illness was significantly higher than in those without infantile eczema until 2 years of age. Infantile eczema, but not other skin eruptions, precedes the development of atopic dermatitis and wheezing illness during early infancy, presumably because of the activation of eosinophils before birth.

From April 2011 to April 2012, we conducted a cross-sectional study in Shanghai, China. A total of 13,335 modified ISAAC questionnaires (response rate: 85.3%) were returned by parents or guardians for 4-6 year-old children. Six dampness-related indicators (visible mold spots, visible damp stains, damp bed clothing, water damage, window pane condensation, and moldy odor) were used to evaluate home dampness-related exposures. In the present study, we applied logistic regression model to reveal associations, dose-response relationships, and statistical interaction effects of these dampness-related exposures, with childhood eczema, during lifetime since birth (ever) and in the last 12 months before the questionnaire. The dampness-related indicators were frequently reported in the perinatal and current residences. Prevalences of eczema ever and in the last 12 months were 22.9% and 13.2%, respectively. The dampness-related indicators were robustly associated and dose-response related with increased risk of eczema ever and in the last 12 months in the logistic regression analyses, with adjusted for potential confounders. Specifically, in the perinatal residence, visible mold spots or damp stains could increase 46% (OR, 95% CI: 1.46, 1.29-1.66) odds of childhood eczema (ever); in the current residence, visible mold spots and visible damp stains could increase 34% (1.34, 1.14-1.58) and 38% (1.38, 1.22-1.56) odds of childhood eczema (ever), respectively. Associations were not appreciably different between boys and girls, nor were they different between children with and without parental history of atopy. In conclusion, perinatal and current dampness-related exposures in the residence perhaps are risk factors for childhood eczema. Copyright © 2015 Elsevier Inc. All rights reserved.

Predicting phenotypes of asthma and eczema with machine learning

PubMed Central

2014-01-01

Background There is increasing recognition that asthma and eczema are heterogeneous diseases. We investigated the predictive ability of a spectrum of machine learning methods to disambiguate clinical sub-groups of asthma, wheeze and eczema, using a large heterogeneous set of attributes in an unselected population. The aim was to identify to what extent such heterogeneous information can be combined to reveal specific clinical manifestations. Methods The study population comprised a cross-sectional sample of adults, and included representatives of the general population enriched by subjects with asthma. Linear and non-linear machine learning methods, from logistic regression to random forests, were fit on a large attribute set including demographic, clinical and laboratory features, genetic profiles and environmental exposures. Outcome of interest were asthma, wheeze and eczema encoded by different operational definitions. Model validation was performed via bootstrapping. Results The study population included 554 adults, 42% male, 38% previous or current smokers. Proportion of asthma, wheeze, and eczema diagnoses was 16.7%, 12.3%, and 21.7%, respectively. Models were fit on 223 non-genetic variables plus 215 single nucleotide polymorphisms. In general, non-linear models achieved higher sensitivity and specificity than other methods, especially for asthma and wheeze, less for eczema, with areas under receiver operating characteristic curve of 84%, 76% and 64%, respectively. Our findings confirm that allergen sensitisation and lung function characterise asthma better in combination than separately. The predictive ability of genetic markers alone is limited. For eczema, new predictors such as bio-impedance were discovered. Conclusions More usefully-complex modelling is the key to a better understanding of disease mechanisms and personalised healthcare: further advances are likely with the incorporation of more factors/attributes and longitudinal measures.

Eczema is a chronic form of childhood disorder that is gaining in prevalence in affluent societies. Previous studies hypothesized that the development of eczema is correlated with changes in microbial profile and composition of early life endemic microbiota, but contradictory conclusions were obtained, possibly due to the lack of minimization of apparent non-health related confounders (e.g., age, antibiotic consumption, diet and mode of delivery). In this study, we recruited seven caesarean-delivered and total formula-fed infants, and comparatively examined the early-life endemic microbiota in these infants with and without eczema. Using 16S pyrosequencing, infants' fecal microbiota were observed to comprise Proteobacteria, Firmicutes, Actinobacteria and Bacteroidetes as the four main phyla, and the presence and absence of specific populations within these four phyla are primarily mediated by ageing. Quantitative analysis of bacterial targets on a larger sample size (n = 36 at 1, 3, and 12 months of age) revealed that the abundances of Bifidobacterium and Enterobacteriaceae were different among caesarean-delivered infants with and without eczema, and the bacterial targets may be potential biomarkers that can correlate to the health status of these infants. Our overall findings suggest that the minimization of possible confounders is essential prior to comparative evaluation and correlation of fecal microbiota to health status, and that stool samples collected from caesarean-delivered infants at less than 1 year of age may represent a good cohort to study for potential biomarkers that can distinguish infants with eczema from those without. These findings would greatly facilitate future efforts in understanding the possible pathogenesis behind certain bacterial targets, and may lead to a timely intervention that reduces the occurrence of early life eczema and possibly allergic disorders in later life.

Atopic dermatitis (AD) is common in the population, and studies have shown that the disease is on the increase. Studies based on hospital records reflect selected populations and may miss less severe cases of AD, and the use of self-reported questionnaires has the drawback of recall bias. To investigate some possible factors influencing recall bias when questionnaires are used to establish the prevalence of childhood eczema in an adult population. A questionnaire regarding past and present eczema was sent to 557 cases (with signs suggesting the diagnosis AD) and 554 matched controls (subjects lacking signs of AD) born during 1960-1969 and identified in school health medical records. Cases and controls were aged 31-42 years at the time of the study and 70.5% returned the questionnaire. Of 403 cases, 29% did not report childhood eczema in the questionnaire. There was a difference between those who did recall their childhood AD (remembering group, RG), and those who did not (forgetful group, FG) in who had documented the diagnostic signs in the school health records. In the RG the signs were reported by both parents and school health personnel in 51% of cases, and in the FG this was true of only 16%. The RG had a higher prevalence of eczema after 15 years of age and of hand eczema. The RG also reported more visits to physicians after the age of 15 years and more time taken as sick leave due to eczema. Several factors influence how well people remember their AD in childhood. These factors include disease activity in adult life, disease severity, and who noticed the eczema in childhood.

While the association of eczema with asthma is well recognized, little research has focused on the potential role of inhalable exposures and eczema. While indoor air quality is important in the development of respiratory disease as children in the U.S. spend the majority of their time indoors, relatively little research has focused on correlated non-respiratory conditions. This study examined the relationship between particulate matter (PM) exposures in preschool age children and major correlates of asthma, such as wheeze and eczema. Air sampling was carried out using a robotic (PIPER) child-sampling surrogate. This study enrolled 128 participants, 57 male and 71 female children. Ages ranged from 3 to 58 months with the mean age of 29.3 months. A comparison of subjects with and without eczema showed a difference in the natural log (ln) of PM collected from the PIPER air sampling (p = 0.049). PIPER's sampling observed an association between the ln PM concentrations and eczema, but not an association with wheezing history in pre-school children. Our findings are consistent with the hypothesis of the role of the microenvironment in mediating atopic dermatitis, which is one of the predictors of persistent asthma. Our findings also support the use of PIPER in its ability to model and sample the microenvironment of young children.

Manifestation of allergic disease depends on genetic predisposition, diet and commensal microbiota. Genetic polymorphism of mothers determines their breast milk glycan composition. One major determinant is the fucosyltransferase 2 (FUT2, secretor gene) that was shown to be linked to commensal microbiota establishment. We studied whether FUT2-dependent breast milk oligosaccharides are associated with allergic disease in breast-fed infants later in life. We analyzed FUT2-dependent oligosaccharides in breast milk samples of mothers (n = 266) from the placebo group of a randomized placebo-controlled trial of prebiotics and probiotics as preventive against allergic disease in infants with high allergy risk (trial registry number: NCT00298337). Using logistic regression models, we studied associations between FUT2-dependent breast milk oligosaccharides and incidence of allergic disease at 2 and 5 years of age. At 2 years, but not at 5 years of age, we observed a presumed lower incidence (p < 0.1) for IgE-associated eczema manifestation in C-section-born infants who were fed breast milk containing FUT2-dependent oligosaccharides. By logistic regression, we observed a similar relation (p < 0.1) between presence of FUT2-dependent breast milk oligosaccharides and IgE-associated disease and IgE-associated eczema in C-section-born infants only. When testing with the levels of breast milk oligosaccharide 2'-fucosyllactose as proxy for FUT2 activity, we observed significant (p < 0.05) associations in the C-section-born infants with 'any allergic disease,' IgE-associated disease, eczema and IgE-associated eczema. The data indicate that infants born by C-section and having a high hereditary risk for allergies might have a lower risk to manifest IgE-associated eczema at 2 years, but not 5 years of age, when fed breast milk with FUT2-dependent milk oligosaccharides. Further studies with larger cohorts and especially randomized controlled intervention trials are required to build on these preliminary observations.

The immunological composition of breast milk differs between mothers. The reasons for these differences and the consequences for the breast-fed infants are poorly understood. The aim of this study was to evaluate the effect of probiotic Lactobacillus reuteri supplementation on the immunological composition of breast milk in relation to sensitization and eczema in the babies. Total IgA, secretory IgA (SIgA), TGF-beta1, TGF-beta2, IL-10, TNF, soluble CD14 (sCD14), and Na/K ratios were analyzed in colostrum and mature milk obtained from women treated with L. reuteri (n = 54) or placebo (n = 55) from gestational week 36 until delivery. Bacteriological analyses of L. reuteri were performed in faecal samples of the mothers. The infants were followed prospectively for 2 yr regarding development of eczema and sensitization as defined by a positive skin prick test and/or circulating allergen-specific IgE antibodies at 6, 12, and 24 months of age. Supplementation of L. reuteri during pregnancy was associated with low levels of TGF-beta2 and slightly increased levels of IL-10 in colostrum. For TGF-beta2, this association was most pronounced in mothers with detectable L. reuteri in faeces. Infants receiving breast milk with low levels of TGF-beta2 were less likely to become sensitized during their first 2 yr of life. A similar trend was observed for development of IgE-associated eczema. The levels of total IgA, SIgA, TGF-beta1, TNF, sCD14, and Na/K ratios in breast milk were not affected by the intake of L. reuteri. None of these parameters correlated with sensitization or development of eczema in the infant, except for high Na/K ratios that associated with increased risk of sensitization. Supplementation with L. reuteri during late pregnancy reduces breast milk levels of TGF-beta2, and low levels of this cytokine are associated with less sensitization and possibly less IgE-associated eczema in breast-fed infants.

The natural history of asthma and atopic diseases begins in utero. Studies investigating the influence of foetal exposure to maternal stressful life events during pregnancy (SLEP) on asthma and atopic diseases are lacking. To test whether the children of mothers who had experienced SLEP are at an increased risk for asthma, atopic eczema and allergic rhinitis. The association between maternal SLEP (at least one among: divorce, mourning or loss of the job) and the occurrence of asthma and atopic diseases in childhood was studied in a population (n = 3854) of children, aged 3-14 yrs, living in Northern Italy. The parents filled in a standardized questionnaire about the children's health and the events occurred to their mothers during pregnancy. Three hundred and thirty-three (9%) of the mothers experienced SLEP. Their children had a statistically significantly higher lifetime prevalence of wheezing (31.6% vs. 23.1%), asthma (8.9% vs. 5.6%), allergic rhinitis (10.9% vs. 7.3%) and atopic eczema (29.7% vs. 21.1%) than those of mothers without SLEP. After adjusting for potential confounders, the foetal exposure to SLEP was positively associated with wheezing (OR: 1.41, 95% CI: 1.03-1.94), asthma (OR: 1.71, 95% CI: 1.02-2.89), allergic rhinitis (OR: 1.75, 95% CI: 1.08-2.84) and atopic eczema (OR: 1.53, 95% CI: 1.11-2.10). The children of mothers who had experienced SLEP were at a moderately increased risk of having wheezing, asthma, eczema and allergic rhinitis during their childhood. Maternal stress during pregnancy might enhance the expression of asthma and atopic phenotypes in children. © 2012 John Wiley & Sons A/S.

Filaggrin is an epidermal protein that has a role in skin barrier function. Filaggrin loss-of-function (FLG-LOF) mutations are a significant risk factor for eczema and atopy, but their association with food allergy (FA) is less clear. We explored the longitudinal relationship between 3 common FLG-LOF mutations and FA using the Isle of Wight birth cohort. FA diagnosis was based on recognized allergic reactions within 4 hours after exposure to known food allergens. Food allergen sensitization (FAS) was identified by using skin prick tests conducted between 1 and 18 years of age to a range of food allergens. Three FLG mutations were genotyped in 1150 (79%) of 1456 children. The temporal relationships between FA, FAS, and eczema in children with FLG mutations were explored by using path analysis with total, direct, and indirect effect models. There was a significant total effect of FLG-LOF mutations on the risk of FA in later childhood at the ages of 10 (odds ratio, 31.46; 95% CI, 2.86 to >100) and 18 (odds ratio, 4.25; 95% CI, 1.55-11.61) years. Path analysis showed that there was no direct effect of FLG-LOF mutations on FA at any age; however, an indirect effect was found on FA at all ages through eczema and FAS in the earlier years. FLG-LOF mutations are associated with FA in older children through eczema and FAS during early childhood. Our results highlight a biologically plausible pathway, which suggests that skin barrier function is important in the development and persistence of FA.

Background Rural residence is protective against atopy and wheeze–rhinitis–eczema symptoms in developed countries, an effect attributed to farming and poor hygiene exposures. There are few data from developing countries addressing this question. We compared atopy and wheeze–rhinitis–eczema symptoms between urban and rural Ecuador, and explored the effects of farming and poor hygiene exposures. Methods We performed cross sectional studies of schoolchildren living in rural and urban Ecuador. Data on symptoms and farming/hygiene exposures were collected by parental questionnaire, atopy by allergen skin prick test reactivity and geohelminth infections by stool examinations. Results Among 2526 urban and 4295 rural schoolchildren, prevalence was: atopy (10.0% vs 12.5%, p=0.06), wheeze (9.4% vs 10.1%, p=0.05), rhinitis (8.1% vs 6.4%, p=0.02) and eczema (5.9% vs 4.7%, p=0.06). A small proportion of symptoms were attributable to atopy (range 3.9–10.7%) with greater attributable fractions for respiratory symptoms observed in urban schoolchildren. Respiratory symptoms were associated with poor hygiene/farming exposures: wheeze with lack of access to potable water; and rhinitis with household pets, no bathroom facilities and contact with large farm animals. Birth order was inversely associated with respiratory symptoms. Area of residence and atopy had few effects on these associations. Conclusions Urban schoolchildren living in Ecuador have a similar prevalence of atopy, eczema and wheeze but a higher prevalence of rhinitis compared with rural children. Some farming and poor hygiene exposures were associated with an increase in the prevalence of wheeze or rhinitis while birth order was inversely associated with these symptoms. PMID:24105783

Thirty-five patients with classical lichen planus (LP) were extensively investigated with special reference to immunohistological changes and histocompatibility (HLA) typing. There was no evidence of lupus erythematosus (LE) in any patient, although one patient with LP and eczema had an elevated titre of antinuclear factor. There was no increased incidence of any HLA type--in particular HLA-B7 and HLA-B8--known to be associated with LE. The results suggest that LE and LP are separate disorders.

Atopic eczema is the commonest inflammatory skin disease of childhood, affecting 15-20% of children in the UK at any one time. Adults make up about one-third of all community cases. Moderate-to-severe atopic eczema can have a profound effect on the quality of life for both sufferers and their families. In addition to the effects of intractable itching, skin damage, soreness, sleep loss and the social stigma of a visible skin disease, other factors such as frequent visits to doctors, special clothing and¿the need to constantly apply messy topical applications all add to the burden of disease. The cause of atopic eczema is unknown, though a genetic pre-disposition and a combination of allergic and non-allergic factors appear to be important in determining disease expression. Treatment of atopic eczema in the UK is characterised by a profusion of treatments aimed at disease control. The evidential basis of these treatments is often unclear. Most people with atopic eczema are managed in primary care where the least research has been done. The objectives of this scoping review are two-fold. To produce an up-to-date coverage 'map' of randomised controlled trials (RCTs) of treatments of atopic eczema. To assist in making treatment recommendations by summarising the available RCT evidence using qualitative and quantitative methods. Data sources included electronic searching of MEDLINE, EMBASE, the Cochrane Controlled Clinical Trials Register, the Cochrane Skin Group specialised register of trials, hand-searching of atopic eczema conference proceedings, follow-up of references in retrieved articles, contact with leading researchers and requests to relevant pharmaceutical companies. Only RCTs of therapeutic agents used in the prevention and treatment of people with atopic eczema of any age were considered for inclusion. Only studies where a physician diagnosed atopic eczema or atopic dermatitis were included. Data extraction was conducted by two observers onto abstraction forms, with discrepancies resolved by discussion. The quality assessment of retrieved RCTs included an assessment of: a clear description of method and concealment of allocation of randomisation, the degree to which assessors and participants were blinded to the study interventions, and whether all those originally randomised were included in the final main analysis. Where possible, quantitative pooling of similar RCTs was conducted using the Cochrane Collaboration's methods. Where statistical heterogeneity was found, sources of heterogeneity in terms of study participants, formulation or posology of intervention, and use of co-treatments were explored. Where pooling was not deemed to be appropriate, detailed descriptions of the study characteristics and main reported results were presented along with comments on study quality. A total of 1165 possible RCTs were retrieved in hard copy form for further scrutiny. Of these, 893 were excluded from further analysis because of lack of appropriate data. The 272 remaining RCTs of atopic eczema covered at least 47 different interventions, which could be broadly categorised into ten main groups. Quality of reporting was generally poor, and limited statistical pooling was possible only for oral cyclosporin, and only then after considerable data transformation. There was reasonable RCT evidence to support the use of oral cyclosporin, topical corticosteroids, psychological approaches and ultraviolet light therapy. There was insufficient evidence to make recommendations on maternal allergen avoidance for disease prevention, oral antihistamines, Chinese herbs, dietary restriction in established atopic eczema, homeopathy, house dust mite reduction, massage therapy, hypnotherapy, evening primrose oil, emollients, topical coal tar and topical doxepin.

Hexavalent chromium in cement is a common cause of occupational allergic contact dermatitis (OACD). Analysis of patch test data during 1999 to 2013 was done. Patients with cement-induced chromate OACD filled the Dermatology Life Quality Index, graded 1 to 5. Of 4846 consecutive patients who were patch tested, 146 (3%) were chromate-sensitive. Of 46 (31.5%) who presented with chromate OACD, 27 (59%) had cement-induced chromate OACD. The proportion of chromate-sensitive patients with clinically relevant cement exposure increased from 7.7% in 2002 to 2004 to 28.7% in 2011 to 2013 (P = 0.04). The median age of presentation was younger than for other chromate-sensitive patients (32 vs 42 years). Hand eczema (88.9%) was the most frequent clinical presentation. Of the 27 with cement-induced chromate OACD, 21 (77.8%) had ongoing dermatitis at the time of the review. Although 14/27 (51.9%) changed their occupation to avoid exposure to cement, symptoms persisted in 9/14 (64.3%). Prolonged exposure to cement before development of symptoms was associated with chronicity. All the symptomatic patients experienced at least a moderate effect on their quality of life (grade 3 or higher on the Dermatology Life Quality Index). We recommend the adoption of the European legislation in Israel, to reduce the prevalence of chromate OACD from cement.

Prominent ear correction is a common operation. Complication as a result of infection has been quoted at between 3% and 5% [Calder JC, Nasaan A. Morbidity of otoplasty: a review of 562 consecutive cases. Br J Plast Surg 1994;47:170-4 and Jeffery SLA. Complications following correction of prominent ears: an audit review of 122 cases. Br J Plast Surg 1999;52:588-90.]. We present two cases referred for ear reconstruction following catastrophic post-operative infection at the time of pinnaplasty, leaving each patient with significant helical rim deformities. Both patients displayed evidence of active post-auricular eczema at the time of their primary surgery. Dermatological research has highlighted the increased colonisation of Staphylococcus aureus in particular within areas of atopic eczema in comparison to normal skin. We advise delaying ear surgery in the presence of a rash in view of the potentially devastating complications that may result. This approach may be extended to all cutaneous surgery where treatment of the rash is advocated prior to embarking on an elective surgical procedure.

This study examines the relationship between community pharmacists’ knowledge, attitudes to information provision and self-reported counselling behaviours in relation to topical corticosteroids and adjunct therapy in atopic eczema. A mixed-methods approach was used whereby data from interviews with community pharmacists were used to design a structured questionnaire that a larger sample of community pharmacists completed anonymously. The questionnaire was completed and returned by 105 pharmacists (36% response rate). Pharmacists showed gaps in their knowledge on the use of topical corticosteroids in atopic eczema but had good understanding on the use of emollients. There was a significant correlation between pharmacists’ attitudes to information provision and their self-reported counselling behaviour for most themes except in relation to corticosteroid safety where less advice was given. Improving attitudes to information provision should correlate with increased counselling behaviour. However, for the theme of corticosteroid safety, further studies are needed to examine why in practice pharmacists are not providing patient counselling on this topic even though most agreed this is a topic patients should know about.

The aim of our study was to find out the magnitude of anxiety and depression in our common dermatological patients and its correlation with age, sex. For this purpose, we used Hospital Anxiety and Depression Scale HADS. The psychometric validity of HADS has been established by validating the questionnaire against the structured psychiatric interviews. A study of anxiety and depression in patients with dermatologic diseases was conducted on the basis of outpatients department in 211 patients with dermatologic diseases; among them were 107 male and 104 female, aged 16 to 75 years. Among them were patients with Acne, Alopecia Areata, Psoriasis, Vitiligo, Neurodermatitis, Scabies, Eczema and Other diseases (Atopic Dermatitis, Chronic Urticaria, Lichen Planus, Herpes Zoster, Melasma, Warts and Etc.). Based on studies of patients reveals that 65.4% of them are anxiety, depression - 56.2%, both anxiety and depression in 24.7%, there figures higher than the dates of other authorizes. As a result of a direct link research risk disorder depressive spectrum with sex, age; in woman anxiety and depression occurs more frequently than men, and anxiety occurs more frequently in young age. Especially there are hight frequencies of manifestation of abuse in patients with Psoriasis (anxiety - 83.3%, depression - 69.4%, both - 38.8%), Eczema (anxiety - 73.3%, depression - 56.6%, both - 26.7%), Acne (anxiety - 78.4%, depression - 54%, both - 21.6%), Vitiligo (anxiety - 66.7%, depression - 60%, both - 33.3%).

Background The low prevalence of allergic disease in the rural tropics has been attributed to the protective effects of chronic helminth infections. There is concern that treatment-based control programmes for these parasites may lead to an increase in the prevalence of allergic diseases. Objective We measured the impact of 15–17 years of anthelmintic treatment with ivermectin on the prevalence of allergen skin test reactivity and allergic symptoms in school-age children. Methods The prevalence of allergen skin test reactivity, exercise-induced bronchospasm and allergic symptoms was compared between school-age children living in communities that had received community-based treatments with ivermectin (for onchocerciasis control) for a period of 15–17 years with those living in geographically adjacent communities that had received no ivermectin. Results The prevalence of allergen skin test reactivity was double in children living in treated communities compared with those in untreated communities (16.7% vs. 8.7%, adjusted OR 2.10, 95% CI 1.50–2.94, P<0.0001), and the effect was mediated partly by a reduced prevalence of Trichuris trichiura among treated children. Ivermectin treatments were associated with an increased prevalence of recent eczema symptoms (adjusted OR 2.24, 95% CI 1.05–4.78, P=0.04) but not symptoms of asthma or rhino-conjunctivitis. The effect on eczema symptoms was not associated with reductions in geohelminth infections. Conclusion Long-term periodic treatments with ivermectin were associated with an increased prevalence of allergen skin test reactivity. There was some evidence that treatment was associated with an increased prevalence of recent eczema symptoms but not those of asthma or rhino-conjunctivitis. Cite this as: P. Endara, M. Vaca, M. E.

A meta-analysis of randomized, placebo-controlled clinical trials of Efamol evening primrose oil in atopic eczema. Where do we go from here in light of more recent discoveries?

PubMed

Morse, N L; Clough, P M

The global incidence of atopic eczema is escalating. While new treatment options are becoming available, previous treatments with certain confirmed benefits are still worth investigating as safe and effective therapies. One such treatment, Efamol evening primrose oil (EPO), was proven efficacious in a 1989 meta-analysis of randomized, double-blind, placebo-controlled clinical trials. A decade of further testing and subsequent independent reanalysis of 26 clinical studies including 1207 patients presented here, establishes that Efamol EPO has a simultaneous, beneficial effect on itch/pruritus, crusting, oedema and redness (erythema) that becomes apparent between 4 and 8 weeks after treatment is initiated. However, the magnitude of this effect is reduced in association with increasing frequency of potent steroid use. This and other confounding variables that are now being reported in the literature may account for historically reported inconsistent patient response. Recent research has uncovered unique complexities in fatty acid metabolism and immune response in the atopic condition beyond those previously reported and may well have identified a subcategory of non-responders and has helped established those that can consistently derive significant benefit. Further research is needed to provide a better understanding of the physiology behind this complex disorder and the beneficial role that fatty acids can play in its development and management. Efamol EPO has a simultaneous, beneficial effect on itch/pruritus, crusting, oedema and redness (erythema) that becomes apparent between 4 and 8 weeks after treatment is initiated.

This study aimed to investigate the relation between environmental influences such as arsenic, cadmium, lead, and mercury, as well as environmental tobacco smoke, pet keeping, and heating systems on the prevalence of atopic eczema. Therefore, a multicenter cross-sectional study of school children aged 5-14 years, including a standardized questionnaire, blood and urine analyses, and a dermatological examination, was undertaken. A cases-control approach was chosen in order to identify relevant risk factors. A total of 2200 school children (response 79.1%) of two areas (Bitterfeld, Hettstedt) polluted by industrial activities and an agricultural control region (Zerbst) of the former German Democratic Republic were examined. Atopic eczema as identified by dermatological examination and history was the outcome variable of interest. Body burden of arsenic and heavy metals and questionnaire data on environmental tobacco smoke exposure, pet keeping, and heating system were investigated as potential risk factors. The overall prevalence of atopic eczema was 2.6%, with higher prevalences in the industrial areas (2.5 and 2.9%) compared to the control area (1.6%, not significant). Bivariate analyses did not reveal statistically significant associations between atopic eczema and tobacco smoke exposure or the body burden of arsenic and heavy metals. According to multiple logistic regression analysis, atopic eczema was significantly more frequent in predisposed families and those who reported keeping guinea pigs (OR=4.37, CI 2.15-8.91), but not other pets, like dogs, cats, and hamsters. In comparison to a distant heating system, a decreased risk was observed in households with central heating system (OR=0.30, CI 0.10-0.90), whereas the presence of a gas heater with an exhaust pipe connection to the wall was associated with a significantly elevated risk for eczema (OR=8.22, CI 2.44-27.66). The heating system and exposure to certain animal allergens are related to the manifestation of atopic eczema. Further studies are needed to clarify how far a causal relationship is reflected by these findings. Copyright 1999 Academic Press.

Gut microbiome and innate immune response patterns in IgE-associated eczema.

Gut microbiome patterns have been associated with predisposition to eczema potentially through modulation of innate immune signalling. We examined gut microbiome development in the first year of life in relation to innate immune responses and onset of IgE-associated eczema over the first 2.5 years in predisposed children due to maternal atopy [www.anzctr.org.au, trial ID ACTRN12606000280505]. Microbial composition and diversity were analysed with barcoded 16S rRNA 454 pyrosequencing in stool samples in pregnancy and at ages 1 week, 1 month and 12 months in infants (n = 10) who developed IgE-associated eczema and infants who remained free of any allergic symptoms at 2.5 years of age (n = 10). Microbiome data at 1 week and 1 month were analysed in relation to previously assessed immune responses to TLR 2 and 4 ligands at 6 months of age. The relative abundance of Gram-positive Ruminococcaceae was lower at 1 week of age in infants developing IgE-associated eczema, compared with controls (P = 0.0047). At that age, the relative abundance of Ruminococcus was inversely associated with TLR2 induced IL-6 (-0.567, P = 0.042) and TNF-α (-0.597, P = 0.032); there was also an inverse association between the abundance of Proteobacteria (comprising Gram-negative taxa) and TLR4-induced TNF-α (rs = -0.629, P = 0.024). This relationship persisted at 1 month, with inverse associations between the relative abundance of Enterobacteriaceae (within the Proteobacteria phylum) and TLR4-induced TNF-α (rs = -0.697, P = 0.038) and Enterobacteriaceae and IL-6 (rs = -0.709, P = 0.035). Mothers whose infants developed IgE-associated eczema had lower α-diversity of Bacteroidetes (P = 0.04) although this was not seen later in their infants. At 1 year, α-diversity of Actinobacteria was lower in infants with IgE-associated eczema compared with controls (P = 0.002). Our findings suggest that reduced relative abundance of potentially immunomodulatory gut bacteria is associated with exaggerated inflammatory cytokine responses to TLR-ligands and subsequent development of IgE-associated eczema. © 2015 John Wiley & Sons Ltd.

Increased risk of eczema but reduced risk of early wheezy disorder from exclusive breast-feeding in high-risk infants.

Breast-feeding is recommended for the prevention of eczema, asthma, and allergy, particularly in high-risk families, but recent studies have raised concern that this may not protect children and may even increase the risk. However, disease risk, disease manifestation, lifestyle, and the choice to breast-feed are interrelated, and therefore, analyzing true causal effects presents a number of methodologic challenges. First, to assess the effect from duration of exclusive breast-feeding on the development of eczema and wheezy disorders during the first 2 years of life in a high-risk clinical birth cohort. Second, to assess any influence from the fatty acid composition of mother's milk on the risk from breast-feeding. We studied disease development during the first two years of life of the 411 infants from the Copenhagen Study on Asthma in Childhood (COPSAC) birth cohort, born to mothers with a history of asthma. We analyzed the effect from duration of breast-feeding before disease onset on the disease risk, avoiding the effect from disease-related modification of exposure (inverse causation). Polyunsaturated fatty acids were measured in breast milk. Breast-feeding significantly increased the risk of eczema adjusted for demographics, filaggrin variants, parents' eczema, and pets at home (N = 306; relative risk, 2.09; 95% CI 1.15-3.80; P = .016) but reduced the risk of wheezy episodes (relative risk, 0.67; 95% CI 0.48-0.96; P = .021) and of severe wheezy exacerbation (relative risk, 0.16; 95% CI 0.03-1.01; P = .051). There was no association between the fatty acid composition of mother's milk and the risk of eczema or wheeze. The risk of eczema was increased in infants with increasing duration of breast-feeding. In contrast, the risk of wheezy disorder and severe wheezy exacerbations was reduced. There were no significant effects from the fatty acid composition of the breast milk on risk of eczema or wheezy disorders. Copyright (c) 2010 American Academy of Allergy, Asthma & Immunology.

To evaluate the style of education in this group of children, "scale versions" according to Stapf were used. Mothers of atopic children were found to be significantly more "strict" in their educational approach compared with control mothers (P less than 0.01). There was no significant difference between the two groups of fathers. In particular, mothers of atopic children significantly more often favored "grown-up" behavior in their children and the capacity to enjoy the joy of children was significantly less pronounced compared with controls. In the children's drawings, children with atopic eczema lacked the "friendly atmosphere" expressed in drawings of control children. Fathers of atopic children were drawn significantly smaller than the respective mothers. In animal drawings, children with atopic eczema mostly selected unpleasant or dangerous animals to describe their parents, brothers, or sisters. From the structured interviews, the following points were remarkable: atopic children more often display aggressive thoughts or behavior against their parents than do controls. Mothers of atopic children react less spontaneously and less emotionally to children's emotions. Maternal affection often takes place as a hygienic ritual or in a body and achievement-oriented fashion. Mothers of atopic children like them to behave in a "grown-up" manner.

Although development of food allergy after liver transplantation is most commonly described in young children, little is known about identification of young liver-transplant recipients who are at risk of food allergy. This study aimed to identify the types of food allergy and the risk factors for the development of food allergy after liver transplantation. This was a retrospective analysis of pediatric liver transplant recipients in our organ transplantation center during 2005-2015. Relevant data of all patients who underwent liver transplantation were extracted from the center's database and the medical records. Differences in patients' characteristics were evaluated for associations between food allergy and potential risk factors. Logistic regression models were used to calculate adjusted odds ratios. We obtained the data of 206 patients under 36 months of age, 42 (20.4%) of whom developed food allergy after liver transplantation. The allergy was IgE-mediated-only in 30 (71.4%) and non-IgE-mediated-only in 10 (23.8%). Multivariate analysis found eczema at liver transplantation to be a significant risk factor (adjusted odds ratio [aOR] 2.41, 95% confidence interval [CI] 1.14-4.77, P < .05). Eczema increased the risk of developing IgE-mediated food allergy after liver transplantation (aOR 3.13, 95% CI 1.41-6.93, P < .01), whereas no significant association was observed with non-IgE-mediated food allergy. We identified eczema at liver transplantation as a significant risk factor for the development of IgE-mediated food allergy after liver transplantation, but not non-IgE-mediated food allergy. Our findings may contribute to a better understanding of the susceptible subgroup requiring special caution and to the establishment of effective strategies for prevention.

Fragrance mix I (FM I) and fragrance mix II (FM II) in the European baseline series are used as screening tools for fragrance contact allergy. In 2005 the European Union (EU) required labelling of 26 fragrances when present in cosmetic products. INCI nomenclature is obligatory for such labelling. To describe frequencies of contact allergy to these 26 fragrance substances, and to evaluate clinical relevance of these positive reactions. Three hundred and twenty patients with eczema suspected of being contact allergy to fragrances or cosmetics were patch tested with the EU-declared fragrance chemicals, FM I and FM II. There were 76 positive reactions in 33 patients. Most reactions were seen to [corrected] hydroxyisohexyl 3-cyclohexene carboxaldehyde in 3.1%, followed by Evernia furfuracea (2.5%) and cinnamyl alcohol (2.5%). Twelve reactions to FM I and II were not confirmed by separate ingredients. Clinical relevance of positive reactions to fragrances was certain in 20/33 (61%). 10.3% of the patients had positive patch tests in the EU-list. Hydroxyisohexyl 3-cyclohexene carboxaldehyde, a component of FM II, was the most frequent allergen, followed by Evernia furfuracea. Since Evernia furfuracea is not part of FM I or FM II, relevant reactions can be missed when only the European baseline series is used.

To compare the patients who underwent surgery for congenital aural atresia (CAA) with congenital aural stenosis (CAS) for the stability of hearing results and complications during long-term follow-up. Retrospective review. Seventy-five CAA patients and fifty CAS patients who underwent congenital meatoplasty with canalplasty and tympanoplasty between 2007 and 2012. Paired comparison analyses detected no significant difference in preoperative ABG but significant changes in postoperative ABG, ΔABG, the number of ABG < 30 dB and ABG < 10 dB between CAA and CAS. Complications such as postoperative stenosis, bony regrowth, external aural canal (EAC) infection, EAC eczema, total deaf, and lateralization of the tympanic membrane (TM) were observed in 61.3% of patients with CAA and 20% of patients with CAS. Chi square test detected significant differences in complications between patients with CAA and CAS (χ(2) = 20.73, p < 0.01). Meatoplasty with canalplasty and tympanoplasty in individuals with CAS can yield reliable and lasting positive hearing results with a low incidence of severe complications. The existence and preoperative condition of patients' TM and EAC skin helped improve hearing results and decrease the incidence of complications. However, the final hearing results and complications required stricter indications for CAA patients.

We report a case of 7-year-old monozygotic twin patients with atopic dermatitis. The HLA haplotypes were HLA A2, A11, B27, B61, DR1, and DR4. Both serum IgE levels and cedar pollen radioallergosorbent test (RAST) scores were high in the twins (elder/younger sister: IgE: 5170/3980 IU/ml and Japansese cedar pollen: >100/64.0) in contrast to low mite and food RAST scores (Dermatophagoides Pterygonium; 0.59/0.4 and egg white 9.24/4.6). The patients showed positive immediate (20 min in both sisters) and delayed (24 hours in elder sister, 24, 48, 72 hours in younger sister) reactions to a scratch test with Japanese cedar pollen. Skin lesions on the face were aggravated and extended to the trunk and extremities during the Japanese cedar pollen season and gradually subsided in summer. Oral provocation with egg white or cow milk showed no exacerbations, and topical corticosteroid did not improve the eczema. In contrast, successful protection from severe scratching behaviors was achieved by use of topical anti-allergic eye drops and wearing nightgowns made by the mother.

Adverse reactions to skin prick testing in children - prevalence and possible risk factors.

Norrman, Gunilla; Fälth-Magnusson, Karin

2009-05-01

Skin prick test (SPT) is usually considered to be a safe procedure, but recently there have been occasional case reports of generalized allergic reactions. This study was performed to delineate the prevalence of, and evaluate possible risk factors for, adverse reactions to SPT in a prospective study. Altogether 5,908 patients aged < or =18 yr from 11 different pediatric settings were included. The adverse reactions were classified into two groups: (1) Generalized allergic reactions (GAR), (2) Vasovagal reactions (VVR). Adverse reactions were observed in 14 out of 5,908 children examined with SPT. Seven of the adverse reactions were GARs and required medication, yielding a 0.12% risk for GAR. Seven of 14 were VVRs, giving the same risk, 0.12%. Identified risk factors for GAR were low age (<1 yr) (RR 6.28) and active eczema (RR 16.98). For VVR, the risk factors were female sex (RR 7.32) and multiple skin pricks performed on a single patient (p < 0.05). We conclude that GARs do occur, albeit rarely, so the need for proper emergency handling should always be acknowledged. The risk factors suggested may help to identify patients who need extra attention.

Background The mechanisms explaining the co-existence of asthma, eczema and rhinitis (allergic multimorbidity) are largely unknown. We investigated the mechanisms underlying multimorbidity between three main allergic diseases at a molecular level by identifying the proteins and cellular processes that are common to them. Methods An in silico study based on computational analysis of the topology of the protein interaction network was performed in order to characterize the molecular mechanisms of multimorbidity of asthma, eczema and rhinitis. As a first step, proteins associated to either disease were identified using data mining approaches, and their overlap was calculated. Secondly, a functional interaction network was built, allowing to identify cellular pathways involved in allergic multimorbidity. Finally, a network-based algorithm generated a ranked list of newly predicted multimorbidity-associated proteins. Results Asthma, eczema and rhinitis shared a larger number of associated proteins than expected by chance, and their associated proteins exhibited a significant degree of interconnectedness in the interaction network.

A number of proteins potentially associated to these multimorbidity processes were also obtained. Conclusions These results strongly support the existence of an allergic multimorbidity cluster between asthma, eczema and rhinitis, and suggest that type 2 signaling pathways represent a relevant multimorbidity mechanism of allergic diseases. Furthermore, we identified new candidates contributing to multimorbidity that may assist in identifying new targets for multimorbid allergic diseases. PMID:28598986

This study examined the hypothesis that emotion and conduct problems (ECPs) may modify the relationships between ambient air pollutants and childhood asthma and eczema. In the cross-sectional study, 4209 French schoolchildren (aged 10e12 years) were investigated between March 1999 and October 2000. Ambient air pollutants exposures were estimated with dispersion modeling. Health outcomes and ECPs were evaluated by validated questionnaires, completed by the parents. Marginal models were used to analyze the relationships of exposures to ambient air pollutants and/or ECPs to asthma phenotypes and current eczema, adjusting for potential confounders. In our population, interactions were found between ECPs and exposures to ambient air pollutants (benzene, carbon monoxide, nitrogen dioxide, nitrogen oxides, particulate matter with an aerodynamic diameter below 10 mm, volatile organic compounds) (P < .20). In addition, ECPs were related to current wheezing (adjusted prevalence odds ratio [aOR], 2.35; 95% confidence interval [CI], 1.59e3.47), current doctor-diagnosed asthma (aOR, 1.82; 95% CI, 1.25e2.66), and current eczema (aOR, 2.21; 95% CI, 1.61e3.02). Children with ECPs had 1.17e1.51 times higher aORs for the associations between ambient air pollutants and asthma phenotypes and current eczema than those without ECPs. ECPs may modify the relationships between ambient air pollutants and childhood asthma and eczema. 2013 Elsevier Inc. All rights reserved.

In 1998, an epidemiological study on asthma and allergic diseases using ISAAC questionnaire in Laos was first conducted in the recommended schools located in Vientiane capital showing that the prevalence of rhinoconjunctivitis and atopic eczema were 23.7% and 7.1% among children aged 13-14 year-old, respectively. This study aimed to reassess the prevalence of rhinoconjunctivitis and atopic eczema using the same ISAAC questionnaire by employing random sampling method and to identify the potential risk factors for these rhinitis and atopic eczema. This school-based cross-sectional study was conducted in Vientiane capital from December 2006 to February 2007. Of 536 children, prevalence of rhinoconjunctivitis and atopic eczema among schoolchildren were 9.3% and 11.8%, respectively. Children with early respiratory infection (AOR = 4.06; p = 0.001), parasitic infestation especially by Opisthorchis viverrini (AOR = 3.41; p < 0.05) were more likely to have rhinitis. While history of measles (OR = 2.24; p < 0.01) and respiratory infection (OR = 1.96; p < 0.05), eating vegetables everyday (AOR = 2.96; p < 0.01) were associated with atopic eczema. The similarity of prevalence of rhinitis and rhinoconjunctivitis were also revealed between children aged 13-14 year-old in this study and 6-7 in the previous study in 1998. The validation study on ISAAC questionnaire in Lao language is needed in order to generalize this questionnaire in Lao.

The mechanisms explaining the co-existence of asthma, eczema and rhinitis (allergic multimorbidity) are largely unknown. We investigated the mechanisms underlying multimorbidity between three main allergic diseases at a molecular level by identifying the proteins and cellular processes that are common to them. An in silico study based on computational analysis of the topology of the protein interaction network was performed in order to characterize the molecular mechanisms of multimorbidity of asthma, eczema and rhinitis. As a first step, proteins associated to either disease were identified using data mining approaches, and their overlap was calculated. Secondly, a functional interaction network was built, allowing to identify cellular pathways involved in allergic multimorbidity. Finally, a network-based algorithm generated a ranked list of newly predicted multimorbidity-associated proteins. Asthma, eczema and rhinitis shared a larger number of associated proteins than expected by chance, and their associated proteins exhibited a significant degree of interconnectedness in the interaction network. There were 15 pathways involved in the multimorbidity of asthma, eczema and rhinitis, including IL4 signaling and GATA3-related pathways. A number of proteins potentially associated to these multimorbidity processes were also obtained. These results strongly support the existence of an allergic multimorbidity cluster between asthma, eczema and rhinitis, and suggest that type 2 signaling pathways represent a relevant multimorbidity mechanism of allergic diseases.

Atopic dermatitis (AD, atopic eczema) is driven by a complex relationship between genetic predisposition and environmental exposures. We sought to determine the impact of specific climatic factors on the US prevalence of AD. We used a merged analysis of the 2007 National Survey of Children's Health from a representative sample of 91,642 children age 0–17 years and the 2006–2007 National Climate Data Center and Weather Service measurements of relative humidity (%), indoor heating degree days (HDD), clear sky UV indices ozone levels, and outdoor air temperature. As a proxy for AD, we used an affirmative response to the NSCH survey question asking whether the participant’s child has been given a doctor diagnosis of “eczema or any other kind of skin allergy” in the previous 12 months. In multivariate models controlling for sex, race/ethnicity, age and household income, eczema prevalence was significantly lower with highest-quartile mean annual relative humidity (logistic regression, adjusted odds ratio [95% confidence interval]=0.82 [0.71–0.96], P=0.01) and issued UV index (0.73 [0.64–0.84], P<0.0001), and with two other factors associated with increased UV exposure. Eczema prevalence was decreased with highest-quartile air temperature (0.80 [0.70–0.92], P=0.002), but increased with 3rd–quartile mean annual HDD (1.26 [1.11–1.43], P=0.0003). This study provides evidence of climate influences on the US prevalence of childhood eczema. PMID:23334343

Herpesviruses and the microbiome.

PubMed

Dreyfus, David H

2013-12-01

The focus of this article will be to examine the role of common herpesviruses as a component of the microbiome of atopic patients and to review clinical observations suggesting that atopic patients might be predisposed to more severe and atypical herpes-related illness because their immune response is biased toward a TH2 cytokine profile. Human populations are infected with 8 herpesviruses, including herpes simplex virus HSV1 and HSV2 (also termed HHV1 and HHV2), varicella zoster virus (VZV or HHV3), EBV (HHV4), cytomegalovirus (HHV5), HHV6, HHV7, and Kaposi sarcoma-associated herpesvirus (termed KSV or HHV8). Herpesviruses are highly adapted to lifelong infection of their human hosts and thus can be considered a component of the human "microbiome" in addition to their role in illness triggered by primary infection. HSV1 and HSV2 infection and reactivation can present with more severe cutaneous symptoms termed eczema herpeticum in the atopic population, similar to the more severe eczema vaccinatum, and drug reaction with eosinophilia and systemic symptoms syndrome (DRESS) is associated with reactivation of HSV6 and possibly other herpesviruses in both atopic and nonatopic patients. In this review evidence is reviewed that primary infection with herpesviruses may have an atypical presentation in the atopic patient and conversely that childhood infection might alter the atopic phenotype. Reactivation of latent herpesviruses can directly alter host cytokine profiles through viral expression of cytokine-like proteins, such as IL-10 (EBV) or IL-6 (cytomegalovirus and HHV8), viral encoded and secreted siRNA and microRNAs, and modulation of expression of host transcription pathways, such as nuclear factor κB. Physicians caring for allergic and atopic populations should be aware of common and uncommon presentations of herpes-related disease in atopic patients to provide accurate diagnosis and avoid unnecessary laboratory testing or incorrect diagnosis of other conditions, such as drug allergy or autoimmune disease. Antiviral therapy and vaccines should be administered promptly when indicated clinically. Copyright © 2013 American Academy of Allergy, Asthma & Immunology. Published by Mosby, Inc.

The epidermal part of the skin is the major interface between the internal body and the external environment. The skin has a specific physiology and is to different degrees adapted for protection against multiple exogenous stress factors. Clothing is the material with the longest and most intensive contact to human skin. It plays a critical role especially in inflammatory dermatoses or skin conditions with an increased susceptibility of bacterial and fungal infections like atopic dermatitis. Previously, we have shown a dose-dependent antibacterial and antifungal activity of silver-loaded seaweed-based cellulosic fibres. We studied the mode of action of silver-loaded seaweed-based cellulosic fiber and performed a broad safety assessment. The principal aim was to analyse the effects of wearing the textile on epidermal skin physiology in 37 patients with atopic dermatitis in a controlled, randomized single-blinded in vivo study. Furthermore, the sensitization potential was tested in a patch test in 111 panellists. We could demonstrate in vitro a dose-dependent scavenging of induced reactive oxygen species by silver-loaded seaweed-based cellulosic fibers. Safety assessment of these fibres showed no detectable release of silver ions. Furthermore, ex vivo assessment after 24 h application both in healthy volunteers and patients with atopic dermatitis by sequential tape stripping and subsequently raster electron microscopy and energy dispersive microanalysis analysis revealed no detectable amounts of silver in any of stratum corneum layers. Serum analysis of silver showed no detectable levels. The in vivo patch testing of 111 volunteers revealed no sensitization against different SeaCell Active (SeaCell GmbH, Rudolstadt, Germany) containing fabrics. The in vivo study on 37 patients with known atopic dermatitis and mild-to-moderate eczema on their arms were randomly assigned to either silver-loaded seaweed fibre T-shirts or to cotton T-shirts for 8 weeks. A significant reduction in Staphylococcus aureus colonization was detectable for the silver T-shirts compared with cotton T-shirts without any changes in non-pathogenic surface bacteria colonization. Furthermore, a more pronounced improvement in barrier function (transepidermal water loss) was observed in mildly involved eczema areas during the first 4 weeks of the study. Stratum corneum hydration and surface pH improved in both treatment groups over time. The tested silver-loaded seaweed fibre can be regarded as safe and seams to be suited for application in bio-active textiles in atopic dermatitis based on its positive in vivo activity.

Chronic hand eczema (CHE) is a common inflammatory skin disease that affects approximately 10% of the population. Systemic alitretinoin has been shown to be effective in patients with CHE who are refractory to topical corticosteroids. To analyse the impact of alitretinoin on the skin barrier genes and protein expression in the skin lesions of patients with CHE. Fifteen patients with CHE were treated with 30 mg daily of alitretinoin for up to 27 weeks. Disease severity was assessed using a clinical score. Skin biopsies from all the patients were evaluated before and after therapy for the expression of Ki-67, various skin barrier genes and thymic stromal lymphopoietin (TSLP) by real-time quantitative polymerase chain reaction and immunohistochemistry. After alitretinoin application, an improvement in the clinical severity of CHE was observed in the majority of patients. Analysis of skin biopsies before treatment showed a significant increase in Ki-67-positive cells in the suprabasal layer and a dysregulated expression of various skin barrier genes, such as claudin 1, loricrin, filaggrin and cytokeratin 10, which were normalized after treatment. TSLP was significantly upregulated in patients with CHE and also normalized after alitretinoin treatment and negatively correlated with filaggrin. Our data indicate that the expression of barrier genes and proteins was normalized following treatment with alitretinoin in patients with CHE. The change in expression levels of these genes correlated with the clinical efficacy, suggesting that alitretinoin exhibits a disease-modifying activity. TSLP is upregulated in CHE and seems to counteract filaggrin expression in the skin. © 2016 British Association of Dermatologists.

To date, the genetic basis of Dubowitz syndrome (short stature, microcephaly, facial abnormalities, eczema) is unknown and vascular complications are not known to be associated with this syndrome. In microcephalic osteodysplastic primordial dwarfism type II (MOPD II; disproportionate short statue, microcephaly, facial abnormalities), however, cerebral aneurysms and other vascular abnormalities are frequent complications. MOPD II is a genetic disorder caused by mutations in the pericentrin (PCNT) gene (21q22). We report on a patient who came to our attention as a 22-year-old with subarachnoid bleeding due to a ruptured cranial aneurysm. Until then, the patient was thought and published to have Dubowitz syndrome; previously, he was treated with coronary bypass surgery for extensive coronary angiopathy. Consecutive genetic testing revealed MOPD II. After clinical stabilization, the patient was discharged to a specialized rehabilitation center where he died due to re-rupture of a cranial aneurysm. In patients with short stature-especially when clinical features are accompanied by vascular complications-MOPD II should be considered as a differential diagnosis leading to consecutive genetic testing. After detection of mutations in the PCNT gene, a full vascular status including cerebral imaging and cardiac evaluation needs to be determined in order to analyze vascular abnormalities and initiate prophylactic treatment.

Thirty seven breast fed infants with eczema were studied to see whether changes in their mothers' diets affected their skin condition. Nineteen mothers and babies took part in a double blind crossover trial of exclusion of egg and cows' milk, and 18 took part in open exclusion of 11 foods followed by double blind challenge to those mothers whose infants seemed to respond. Babies were examined at the beginning and end of each dietary period, and the extent and severity of the rash were given a numerical score. The eczema improved in six infants when their mothers avoided egg and cows' milk and worsened again when these were reintroduced. Two infants suffered gastrointestinal reactions after maternal ingestion of egg and cows' milk, one developing colitis. Maternal dietary exclusion seems to benefit some breast fed babies with eczema.

Food allergy (FA) in childhood has been shown to be more prevalent in those born in autumn and winter. The mechanisms of this season-of-birth effect remain unclear, although shortage of vitamin D during infancy has been considered one possible mechanism. The purpose of this study was to investigate the effect of eczema on the season-of-birth effect on FA in infancy. A questionnaire survey on the prevalence of allergic diseases was completed by the parents of 14 669 Japanese schoolchildren, aged 7-15 years, in Kyoto City, Japan. Logistic regression models were constructed to compare the prevalence of FA in infancy according to season of birth. Those born in autumn and winter had a significantly higher prevalence of FA in infancy compared to those born in spring and summer in a multivariate model (4.8% vs 3.6%, P = 0.001). The difference, however, was no longer significant when eczema before 6 months was included as either an additional or only confounding factor. The difference among those with and without eczema before 6 months was further analyzed, and it was found that, in both groups, there was no difference between those born in spring and summer and those born in autumn and winter. The season-of-birth effect on FA in infancy was significantly affected by the existence of eczema before 6 months in Japanese children. Eczema before 6 months may be the factor directly related to the season-of-birth effect on FA in infancy. © 2012 The Authors. Pediatrics International © 2012 Japan Pediatric Society.

We sought to examine the relationship globally between UVR dose exposure and current eczema prevalences. ISAAC Phase Three provided data on eczema prevalence for 13- to 14-year-olds in 214 centers in 87 countries and for 6- to 7-year-olds in 132 centers in 57 countries. Linear and nonlinear associations between (natural log transformed) eczema prevalence and the mean, maximum, minimum, standard deviation, and range of monthly UV dose exposures were assessed using linear mixed-effects regression models. For the 13- to 14-year-olds, the country-level eczema prevalence was positively and linearly associated with country-level monthly mean (prevalence ratio = 1.31 [95% confidence interval = 1.05-1.63] per kJ/m 2 ) and minimum (1.25 [1.06-1.47] per kJ/m 2 ) UVR dose exposure. Linear and nonlinear associations were also observed for other metrics of UV. Results were similar in trend, but nonsignificant, for the fewer centers with 6- to 7-year-olds (e.g., 1.24 [0.96-1.59] per kJ/m 2 for country-level monthly mean UVR). No consistent within-country associations were observed (e.g., 1.05 [0.89-1.23] and 0.92 [0.71-1.18] per kJ/m 2 for center-level monthly mean UVR for the 13- to 14- and 6- to 7-year-olds, respectively). These ecological results support a role for UVR exposure in explaining some of the variation in global childhood eczema prevalence. Copyright © 2017 The Authors. Published by Elsevier Inc.

The relationship between urbanisation and the symptom prevalence of asthma, rhinoconjunctivitis and eczema is not clear, and varying definitions of urban extent have been used. Furthermore, a global analysis has not been undertaken. This study aimed to determine whether the symptom prevalence of asthma, rhinoconjunctivitis and eczema in centres involved in the International Study of Asthma and Allergies in Childhood (ISAAC) were higher in urban than rural centres, using a definition of urban extent as land cover from satellite data. A global map of urban extent from satellite images (MOD500 map) was used to define the urban extent criterion. Maps from the ISAAC centres were digitised and merged with the MOD500 map to describe the urban percentage of each centre. We investigated the association between the symptom prevalence of asthma, rhinoconjunctivitis and eczema and the percentage of urban extent by centre. A weak negative relationship was found between the percentage of urban extent of each ISAAC centre and current wheeze in the 13-14-year age group. This association was not statistically significant after adjusting for region of the world and gross national income. No other relationship was found between urban extent and symptoms of asthma, rhinoconjunctivitis and eczema. In this study, the prevalence of symptoms of asthma, rhinoconjunctivitis and eczema in children were not associated with urbanisation, according to the land cover definition of urban extent from satellite data. Comparable standardised definitions of urbanisation need to be developed so that global comparisons can be made.
