ABSTRACT To explore the prevalence of common food and aeroallergens sensitization in early childhood skin diseases. and to compare the pattern of common food and aeroallergens sensitization before and after 6 months among infants with atopic dermatitis (AD).
All skin prick tests (SPTs) performed on children pound18 months of age managed at the pediatric dermatology clinic of an university-affiliated teaching hospital over a 16-month period were examined.
There was generally no difference in the pattern of sensitization to common food and aeroallergens between AD patients and non-AD young children with miscellaneous dermatological or gastrointestinal conditions. Dust mites were the only common aeroallergens in these patients; whereas egg and peanuts were the common sensitizing food allergens. Cat and dog fur as aeroallergens, soy bean, orange and beef as food allergens were relatively uncommon among the studied subjects. In AD, infants pound 6 months were generally naive to aeroallergens but became sensitized to the D. Pteronyssinus in the next 12 months of age. 80% of these infants were not sensitized to cow's milk and none sensitized to soybean.
Atopic sensitization to common allergens was common in early childhood with or without AD. Majority of young infants were not sensitized to milk, and develop eczema before they show atopy to the milk or soy allergens.

    ABSTRACT: Atopic eczema is a common and distressing disease. This study aimed to review the age-dependent pattern of atopic sensitization to food and aeroallergens in patients with eczema by skin prick testing. The results of skin prick test (SPT), serum IgE, bronchial challenge test, and family history of atopy in eczema patients seen at a pediatric dermatology clinic were reviewed. SPT results were available in 816 eczema patients. In these patients, 90% had atopic sensitization to at least one aeroallergen, 69% to at least one food allergen, and 94% to at least one allergen by SPT. Together with a family history of atopy in parents or siblings and a personal history of airway atopies, 97% and 99.8% of the patients were atopic, respectively. Bronchial hyper-reactivity (BHR) was demonstrated in 44% of 339 patients. Aeroallergen was more prevalent than food allergen sensitization among children older than 10 years. The mites (D. pteronysissnus, D. farinae and Blomia Tropicalis) were the most prevalent allergens regardless of age and BHR, but D. pteronysissnus and D. farinae sensitization were more prevalent among BHR-positive patients. Beef is the least sensitized food protein in all ages. The majority of patients with eczema are atopic to aeroallergens. The mites (D. pteronysissnus, D. farinae and Blomia Tropicalis) are the most prevalent allergens regardless of age and BHR.

    ABSTRACT: Atopic eczema is a common and distressing disease. This study aims to review PubMed indexed research statistics on atopic eczema over a-10 year period to investigate the clinical relevance and research interest about this disease. PubMed (a service of the U.S. National Library of Medicine) was searched for the terms "atopic dermatitis" and "eczema", with limits activated (Humans, Clinical Trial, Meta-Analysis, Randomized Controlled Trial, English, published in the last 10 years), and editorials, letters, practice guidelines, reviews, and animal studies excluded. Journal impact factor (IF) is in accordance with Journal Citation Report (JCR) 2009, a product of Thomson ISI (Institute for Scientific Information). A total of 890 articles were retrieved. Taking out publications that were irrelevant and those without an impact factor, 729 articles were obtained. These articles were grouped into dermatology (n = 337, mean IF: 3.01), allergy/immunology (n = 215, mean IF: 4.89), pediatrics (n = 118, mean IF: 2.53) and miscellaneous subject categories (n = 142, mean IF: 5.10). The impact factors were highest in the miscellaneous category (p = 0.0001), which includes such prestigious journals as the New England journal of Medicine (n = 1, IF: 47.05), the Lancet (n = 4, IF: 30.76) and BMJ (n = 6, IF: 13.66). There was no publication in any family medicine or general practice journal. The British Journal of Dermatology (n = 78), Pediatric Allergy and Immunology (n = 49) and Journal of Allergy and Clinical Immunology (n = 46) had the highest number of publications on the subject. Atopic eczema ranked higher in impact factors in allergy/immunology although more publications appeared in the dermatology category. Atopic eczema is a multidisciplinary disease. Its clinical relevance and research interests are definitely beyond that of a mere cutaneous disease. Investigators may consider allergy/immunology and miscellaneous journal categories for higher impact of their research.

    ABSTRACT: OBJECTIVE: To evaluate if eczema severity is associated with blood levels of immunoglobulins, white cell differentials and complements. METHODS: White cell differentials, levels of serum immunoglobulins and complements of patients with eczema and miscellaneous non-eczema skin diseases were measured. Eczema severity and quality of life were assessed by SCORAD, Nottingham Eczema Severity Score (NESS) and Children's Dermatology Life Quality Index (CDLQI). Correlations were analyzed by Pearson's correlation test for parametric data and Spearman's rho correlation test for non-parametric data. RESULTS: Serum IgE and peripheral blood eosinophil percentage were significantly higher in patients with eczema than other non-eczema skin diseases. Levels of IgE (log-transformed), IgA and IgG correlated with objective SCORAD (r = 0.52, 0.40, 0.29, respectively). Levels of eosinophil, neutrophils, lymphocytes and complements also correlated with objective SCORAD, with the eosinohil/lymphocyte ratio showing the highest correlation (r = 0.60, p < 0.01). Ratios of IgE/IgA, IgE/IgG, eosinophils/lymphocytes, eosinophils/neutrophils correlated positively with CDLQI. IgM appeared to have no correlation with eczema. CONCLUSIONS: Blood levels of IgE, IgA, IgG,eosinophils, lymphocytes, neutrophils and complements pathophysiologically correlate with eczema severity. Eosinophil/lymphocyte ratio may represent a readily-available objective laboratory correlate of eczema severity. Eczema is a complex atopic disease involving many cellular and humoral components of the immune system.
