Manifestation of atopic eczema in children after heart transplantation in the first year of life.

Children undergoing heart transplantation in the first year of life appear in clinical observation to develop atopic eczema at an above-chance frequency despite immunosuppressive therapy with cyclosporine A. A clinical study was undertaken to clarify the extent to which those children develop atopic eczema with above-chance frequency. In this cross-sectional study, we examined 41 consecutive children after heart transplantation. Twenty-seven underwent heart transplantation in the first year of life, seven after the first birthday, and seven had cardiac surgery other than heart transplantation in the first year of life and served as a control group. Atopic eczema was diagnosed in 11 out of 27 children with heart transplant in the first year of life. No atopic eczema was diagnosed in the other two groups. Children undergoing heart transplant prior to the first birthday apparently develop atopic eczema more frequently than children whose surgery was performed after the first birthday, and also more frequently than children undergoing organ-preserving procedures, despite immunotherapy. It remains an open question whether a surgical procedure within the first months of life with subsequent immunosuppression causes an alteration in the reactivity of the immune system in these children compared to older children which promotes the occurrence of atopic eczema despite immunosuppression.

Pediatric atopic eczema: the impact of an educational intervention.

Patient education has been regarded as having a key role in the self-management of atopic eczema. However, the relationship between the educational interventions and clinical outcomes including severity of eczema, quality of life, and family impact has not been rigorously examined. The purpose of this longitudinal randomized controlled study was to evaluate the impact of an intensive education program with a focus on dermatology and immunology designed for parents and children diagnosed with atopic eczema. The intention of this study was not to change treatment regimes prescribed by the patient's physician. The Scoring Atopic Dermatitis rating system was used for assessment of disease impact, and the impact on quality of life was quantified by using the Children's Dermatology Life Quality Index, Infants' Dermatology Quality of Life Index, and Dermatitis Family Impact. A total of 61 pediatric patients (0-16 years) diagnosed with atopic eczema from the metropolitan area of Adelaide were randomized to either the control or intervention group. Results of the study showed that the intervention group had a significant improvement in the scoring atopic dermatitis measure when compared to the control group at week 4 and week 12. Quality of life measures did not significantly improve with decreased severity of eczema except in the group of children aged 5-16 years which, despite small numbers, showed a significant improvement in quality of life scores. These findings suggest that education provides an important role in decreasing the severity of eczema.

Oral challenge with metal salts. (II). Various types of eczema.

299 patients with chronic dermatitis of obscure origin were challenged orally in a controlled study with 2.5 mg nickel, 2.5 mg chromium, and 1 mg cobalt given as salts of the respective metals. Flares of the dermatitis were seen in 12 of 61 patients with patch-test-negative hyperkeratotic eczema, in 9 of 32 patients with patch-test-negative perianal eczema, and in 7 of 143 patients with various other patch-test-negative eczemas. In this latter group, flares were seen only among patients with nummular eczema or hand eczema. Among 34 patients with various positive patch tests not relevant to the current dermatitis, 3 with hand eczema experienced flares. Patients who reacted to oral challenge with the metal salt to which they had a positive patch test, included 3 of 9 with nickel allergy, 2 of 5 with cobalt allergy and 6 of 15 with chromate allergy. These patients were tested openly. Low metal diets were prescribed for 33 patients who had flares after oral challenge with specific metal salts. For 23 of these, the dermatitis cleared or improved markedly after following the diet for at least 4 weeks. Responses to a questionnaire sent to the 23 patients indicated that 16 had followed the prescribed diet rigorously or intermittently for at least a year.

Psychosocial adjustment in preschool children with atopic eczema.

Atopic eczema is a chronic skin disorder that is most common in early childhood, an important stage in the child's social and emotional development. The psychiatric adjustment and mother-child attachment in 30 preschool children with severe atopic eczema was compared with 20 matched controls. Patients with eczema had a significant increase in behaviour symptoms, 7/30 (23%) v 1/20 (5%); with significant excess of dependency/clinginess, 15/30 (50%) v 2/20 (10%); fearfulness, 12/30 (40%) v 2/20 (10%); and sleep difficulty, 19/30 (63%) v 9/20 (45%), but there was no significant difference between the two groups in the security of attachments, 25/29 (86%) v 14/20 (70%). Significantly fewer mothers of children with atopic eczema were in outside employment, 8/29 (27%) v 13/20 (65%), or felt supported socially, 10/29 (34%) v 13/20 (65%). Significantly more of them, 9/30 (30%) v 1/20 (5%), felt particularly stressed in relation to their parenting and less efficient in their disciplining of the affected child. In spite of this and at variance with earlier reports in the literature, they did not display negative attitudes towards their child. On the contrary mothers had a positive empathic attitude towards the child, 7/14 (50%) v 2/16 (12%). Child behaviour problems, 7/14 (50%) v 2/16 (12%), and maternal distress, 12/14 (85%) v 5/16 (31%), were significantly more common in the more severely affected children. Minor behaviour problems and parenting distress are important features of severe atopic eczema in early childhood but atopic eczema does not lead to insecurity of the mother-child attachment.

Gastrointestinal symptoms in atopic eczema.

AIMS: To determine the prevalence of gastrointestinal symptoms in children with eczema and the association of such symptoms with the extent of eczema or skin prick test results. METHODS: Sixty five children with atopic eczema and a control group matched for age and sex were recruited. Their parents completed a questionnaire about the children's gastrointestinal symptoms. The children's skin was examined; their weight, height, and abdominal circumference were measured; and skin prick tests were carried out. RESULTS: Gastrointestinal symptoms, especially diarrhea, vomiting, and regurgitation, were more common in the children with eczema. Diarrhea appeared to be associated with the ingestion of specific foods. Gastrointestinal symptoms were related to diffuse eczema and positive skin prick tests to foods. There was no anthropometric differences between the patient and control groups. CONCLUSIONS: A gastrointestinal disorder is common in children with eczema, especially with diffuse distribution. This may be responsible for substantial symptoms and may play a part in the pathogenesis of the disease and in the failure to thrive with which it is sometimes associated.

Hygiene levels in a contemporary population cohort are associated with wheezing and atopic eczema in preschool infants.

BACKGROUND: The hygiene hypothesis states that insufficient exposure to certain infectious agents during childhood increases the risk of developing asthma and atopic diseases. Improvements in hygiene levels may be partly responsible for this decline in exposure. AIMS: To assess whether hygiene levels in infancy are associated with wheeze and/or atopic eczema, independent of a number of possible confounding factors. METHODS: Data were gathered from the Avon Longitudinal Study of Parents and Children (ALSPAC). Parental self completion questionnaires provided symptom data on infant wheeze and atopic eczema at 0-6 months and 30-42 months, respectively. A simple hygiene score was derived using questionnaire responses at 15 months, which ranged from least hygienic to most hygienic. Multivariable logistic regression models analysed the effect of hygiene scores on health outcomes, while adjusting for a number of important confounding variables. RESULTS: Increasing hygiene scores were independently associated with wheezing (OR = 1.04; 95% CI: 1.00 to 1.08) and atopic eczema (OR = 1.04; 95% CI: 1.01 to 1.07) between 30 and 42 months, but not in the first six months. The odds ratio was higher for atopic eczema if the rash was reported to have become sore and oozy (OR = 1.09; 95% CI: 1.02 to 1.16). CONCLUSIONS: High levels of hygiene at 15 months of age were independently associated with wheeze and atopic eczema reported between 30 and 42 months, and there was an increased risk for children with more severe eczema during this period. The importance of hygiene in public health should not be dismissed; however, the creation of a sterile environment through excessive cleanliness may potentially be harmful to the immune system.

High frequency of detection of herpes simplex virus DNA in the oral cavity of patients with eczema herpeticum.

BACKGROUND: It has been reported that herpes simplex virus (HSV) DNA was detected in the oral cavity of patients with herpes labialis under various conditions such as during oral surgery. OBJECTIVE: The frequency of detection of oral HSV DNA was compared between first or recurrent episodes of eczema herpeticum and recurrent type herpes labialis. PATIENTS AND METHODS: Oral swabs were collected from 7 patients with eczema herpeticum and 9 with herpes labialis. The detection of oral HSV DNA was performed by the polymerase chain reaction method. RESULTS: Oral HSV DNA was detected in 6 out of 7 patients (86%) with eczema herpeticum and 3 of 9 (33%) with herpes labialis. CONCLUSIONS: The high frequency of oral HSV DNA detection in eczema herpeticum suggests that subclinical herpetic lesions may develop in the oral cavity of patients with a first episode of eczema herpeticum or may occur during asymptomatic oral HSV shedding in people with recurrent eczema herpeticum.

Infantile eczema at one month of age is associated with cord blood eosinophilia and subsequent development of atopic dermatitis and wheezing illness until two years of age.

BACKGROUND: 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. METHODS: 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. RESULTS: 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. CONCLUSION: 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.

Atopic eczema, Langerhans cells and allergy.

While the pathomechanisms of respiratory atopy are rather well established, the role of IgE-mediated hypersensitivity in the elicitation and maintenance of eczematous skin lesions in atopic eczema is still controversial. Few diseases are characterized by an equally elevated production of IgE antibodies as atopic eczema. Many authors, however, regard this only as epiphenomenon. On the other hand, there is clearcut clinical evidence for exogenous elicitation of atopic eczema by contact with aero or food allergens. A variety of hypotheses may help to explain the participation of IgE antibodies in the induction of eczema: vasoactive mediators secreted by skin mast cells or basophils after allergen contact may produce itch, contact urticaria or a 'late-phase-reaction' with consequent eczematous skin changes further maintained by scratch responses. Recent investigations stress a possible role of Langerhans cells in the epidermis with a low affinity receptor for IgE with possible function for antigen presentation, mediator release or regulatory interactions. Certain cytokines such as interleukin-4 or gamma-interferon are able to enhance the expression of the IgE-receptor on the surface of Langerhans cells. IL-4 and gamma-interferon act synergistically in this respect on Langerhans cells, contrary to B cells. Furthermore lymphocytes may act directly via certain cytokines (e.g. histamine releasing factor, chemotactic factors etc.) on mast cells or eosinophil granulocytes in a proinflammatory sense. Eosinophils seem also to be involved in the inflammatory response in atopic eczema by releasing products such as major basic protein (MBP) or eosinophil cationic protein (ECP) which has been found to be elevated in severe atopic eczema.(ABSTRACT TRUNCATED AT 250 WORDS)

Elevated serum levels of soluble adhesion molecules ICAM-1 and ELAM-1 in patients with severe atopic eczema and influence of UVA1 treatment.

BACKGROUND: ICAM-1 is known to be strongly expressed on keratinocytes in lesional atopic eczema correlating with the degree of inflammation. ELAM-1 was found to be expressed on dermal vascular endothelium in lesional atopic eczematous skin. OBJECTIVE: The present study was performed to investigate whether elevated serum levels of soluble forms of these molecules are detectable in patients with severe atopic eczema and whether these parameters could be useful markers for disease activity. METHODS: Serum levels of soluble ICAM-1 (sICAM-1) and ELAM-1 (sELAM-1) were measured by ELISA in 18 patients with severe atopic eczema before and after UVA1 therapy. RESULTS: Before onset of treatment, serum sICAM-1 (565 +/- 99 ng/ml) and sELAM-1 (89.7 +/- 29.9 ng/ml) levels were significantly (p < 0.001) elevated compared to 22 healthy control persons (296 +/- 46 and 48.8 +/- 22.7 ng/ml). After achievement of significant clinical improvement after 3 weeks of UVA1 therapy, there was neither a decrease in serum sICAM-1 nor in sELAM-1 levels. The posttherapeutic serum sICAM-1 and sELAM-1 values remained elevated (p < 0.001) above the normal range. CONCLUSION: Based on these data we suggest that (1) serum sICAM-1 and sELAM-1 are elevated in patients with severe atopic eczema, (2) sICAM-1 does not decrease together with reduction of ICAM-1-positive keratinocytes in atopic eczema following clinical improvement and might therefore be mainly of a different origin, i.e. leukocytes/endothelial cells, and that (3) sICAM-1 and sELAM-1 seem not to be suitable markers of actual disease activity in severe atopic eczema.

Prevalence of symptoms of asthma, rhinitis, and atopic eczema among Brazilian children and adolescents identified by the International Study of Asthma and Allergies in Childhood (ISAAC) - Phase 3.

OBJECTIVES: To determine the prevalence of symptoms of asthma, rhinitis, and atopic eczema among schoolchildren aged 6 to 7 years and adolescents aged 13 to 14 years in 20 Brazilian cities by using the standardized ISAAC written questionnaire, and to assess the association of this prevalence with latitude, altitude and average annual temperature of collaborating centers. METHODS: Schoolchildren and adolescents from five Brazilian regions participated in the study, totaling 23,422 ISAAC questionnaires answered by schoolchildren's parents and 58,144 questionnaires answered by adolescents. The values for latitude, altitude and average annual temperature were obtained from the Brazilian Institute of Geography and Statistics. RESULTS: The mean prevalence rates among schoolchildren and adolescents were respectively 24.3 and 19.0% for active asthma; 12.6 and 14.6% for rhinoconjunctivitis; and 8.2 and 5.0% for atopic eczema. A significant negative association was observed between latitude and physician-diagnosed asthma among schoolchildren, severe asthma, physician-diagnosed asthma, eczema and atopic eczema among adolescents. No association with altitude was found. CONCLUSIONS: The prevalence of asthma, rhinitis and atopic eczema in Brazil varies considerably. Higher prevalence rates, especially of asthma and eczema, were found at centers located closer to the equator.

Stigmata of atopic constitution in patients with atopic eczema or atopic respiratory disease.

In the diagnosis of atopic eczema, minor physical markers (stigmata) frequently provide valuable clues. The prevalence of nine stigmata (dry skin, hyperlinearity of the palms or soles, infraorbital fold, white dermographism, facial pallor, orbital darkening, Hertoghe's sign, low hairline) was evaluated in 34 atopic eczema patients without atopic respiratory disease, in 16 patients with allergic rhinitis and/or asthma without atopic eczema, and in 23 controls without atopic respiratory or eczematous disease, and with negative results at prick testing with three common aeroallergens. Compared with controls, all features except Hertoghe's sign were significantly (p less than 0.01) more frequent in atopic eczema, and, except for Hertoghe's sign, dry skin and white dermographism, they were significantly (low hairline, p less than 0.05; others, p less than 0.01) more frequent also in respiratory disease. The prevalence of most stigmata did not differ significantly (p greater than 0.05) in cutaneous vs. respiratory atopic disease, only dry skin being more frequent in atopic eczema (p less than 0.05). Although not specific, most stigmata are characteristic markers not only of atopic eczema, but of atopy as such.

Children with atopic eczema. I: Clinical response to food elimination and subsequent double-blind food challenge.

The role of foods in the exacerbation of atopic eczema was studied by offering a food elimination diet and subsequent random order, double-blind food challenges to 91 eczematous patients, [49 males and 42 females, median age 4.5 years (range 0.5-15)]. Eczema improved in 49 of 66 (74 per cent) (skin score fall greater than or equal to 3) after stopping cows' milk, eggs and various other foods, with significant decreases in erythema, excoriation, lichenification and extent of eczema. One hundred and ninety-four food challenges were given to 64 patients who had shown objective or subjective improvement. Eczema and associated symptoms were significantly worse after cows' milk and tomato compared with placebo. Egg did not worsen eczema, but 48 per cent of 44 challenges were incomplete, mainly due to hypersensitivity reactions and challenge refusal. The longer a food had been avoided, the less likely was the chance of a positive food reaction. Clinical history did not predict response to dietary manipulation. A standard elimination diet avoiding cows' milk, egg, tomatoes and possibly colours and preservatives should help up to three-quarters of patients, and is easy to implement with the help of a dietician. This diet may be considered in all children with moderate or severe eczema.

Children with atopic eczema. II: Immunological findings associated with dietary manipulations.

A group of 91 children with atopic eczema entered a study where clinical and immunological features were compared before and after a food elimination diet, and after double blind randomized food challenges in which a food was given for several days at a time. Eczema improved significantly during the diet and became worse on food challenges. The clinical outcome of food elimination could not be predicted by the initial skin prick test results, serum immunoglobulins, total or food-specific IgE, or complexed IgG or IgE. There was a tendency for patients whose eczema did not improve after food elimination to have higher initial serum IgG levels, without a corresponding increase in skin infections. The radioallergosorbent test to soy gave a higher result in those who improved on diet. No significant changes in serum or complexed immunoglobulins occurred over the period of food elimination or subsequent food challenge. Results of food challenges could not be predicted by initial serum immunoglobulin levels. A history of spring/summer exacerbations of eczema correlated with positive skin prick tests to silver birch pollen, but not to grass pollen. Serological tests did not help in planning food diets in atopic eczema, and the immunological studies did not delineate any particular mechanism by which foods might exacerbate eczema.

[Professional hand eczema and atopy. A clinical prospective study on correlation].

683 patients with hand eczema were examined for history and clinical signs of atopy. 242 of these patients suffered from occupational eczema. In more than 50% of this latter group we saw at least 3 references to atopy. This rate exactly corresponds to one established in 441 patients without industrial eczema but with predominantly definite atopic eczema. Thus, atopy exists largely in patients with occupational eczema and in fact furthers the incidence of this disease relevant in social medicine. Early diagnosis of atopy resulting in efficient vocational guidance can diminish the number of cases of industrial eczema.

Are viral warts seen more commonly in children with eczema?

BACKGROUND AND DESIGN: We sought to test the hypothesis that warts are seen more commonly in individuals with eczema by analyzing skin examination data from a national birth cohort study of 9263 British children born between March 3 and 9, 1958. RESULTS: Warts were seen less frequently in those with visible eczema at ages 11 and 16 years (relative risk, 0.60; 95% confidence intervals, 0.37 to 0.95; P = .03). This inverse association persisted after adjustment for potential confounders and was consistent within each age and sex group for children with a history of eczema who did not have visible eczema at the time of examination and for children with asthma/wheezy bronchitis regardless of eczema status. Visible acne or psoriasis was not associated with a decreased prevalence of warts. CONCLUSIONS: These findings contradict previous suggestions of an increased risk of viral warts in atopic eczema and raise new questions regarding the role of cell-mediated immunity in atopic subjects.

Differences in prevalence of asthma, rhinitis, and eczema between parental and self-completed questionnaires in adolescents.

This study was undertaken to compare, for the first time in a developing country, the prevalence of asthma, rhinitis, and eczema in children aged 13-14 years when questionnaires from the International Study of Asthma and Allergies in Childhood (ISAAC) were independently completed by children and parents. A random sample of 3,178 children completed the ISAAC questionnaire at school, while in another sample of 3,387 children, the questionnaire was completed by their parents at home. The prevalence of asthma, rhinitis, and eczema symptoms was significantly higher when questionnaires were completed by adolescents themselves rather than by the parents, particularly for those symptoms that could be better perceived by children or that were more severe, e.g., wheezing with exercise, severe episodes of wheezing, nocturnal cough, and awaking with wheezing in the last 12 months. The diagnosis of hay fever and eczema was also reported more frequently by adolescents compared to their parents. The prevalence of asthma ever and wheezing in the last 12 months was not significantly different between the two samples. In a randomly selected subset of 550 pairs where adolescents and parents came from the same family, asthma ever had the highest agreement (kappa = 0.72, 95% CI: 0.64-0.80), but agreement was poor for rhinitis and eczema ever. In conclusion, the prevalence of asthma, rhinitis, and eczema symptoms varied according to whether the information was reported by independent samples of adolescent or parents. However, the prevalence of wheezing in the last 12 months and asthma ever was quite similar between adolescents and parents, suggesting that these questions are crucial for assessing asthma in epidemiological studies.

Intestinal permeability in patients with eczema and food allergy.

Polyethylene glycol (PEG) was used as a probe molecule to investigate intestinal absorption in eight patients with eczema and evidence of food allergy and ten with eczema alone. In both groups absorption of molecules of larger molecular weight was greater than in normal subjects but absorption of molecules of low molecular weight was normal. There was no difference in absorption between eczema patients with or without food allergy. These results suggest that there is an intestinal mucosal defect in eczema which exists whether or not there is coexistent food allergy. Half the patients with eczema alone and two of the eight with food allergy had more of the large molecular weight PEG recovered in their urine in the second 12 h after ingestion than in the first 12 h. This could be the result of abnormal permeability in the more distal small bowel or even in the colon.
