Reliability of atopy patch tests in detecting protein sensitization in atopic dermatitis: a vehicle comparison

The etiopathogenesis of the nummular eczema is not fully known. Various causative factors have been proposed, and among these only a few studies investigate the relevance of contact allergy. Here, we present a case of nummular contact eczema in an 8-year-old allergic to perfumes. Since atopic dermatitis may also present with different clinical phenotypes, among which nummular eczema is quite frequent, the possible significant differences between non-atopic and atopic nummular diseases are considered. Based on the high incidence of contact sensitization in all cases of nummular eczema, it is recommended to perform patch tests for diagnostic-preventive purposes.

Aim of our study was to evaluate the importance of atopy patch testing with aeroallergens as a diagnostic method in patients suffering from atopic dermatitis. Method: The complet dermatological and allergological examinations were performed in 29 patients; 10 men, 19 women with the average age of 27.8 years, min. 17, max. 57 years; with the median SCORAD 24.2 points, s.d. 13.3 points. Wormwood, grass, dog dander, cat dander, dermatophagoides pharinae, dermatophagoides pteronyssinus and birch pollen were examined in diagnostic procedures. Skin prick tests, specific IgE were examined; the atopy patch tests were performed with aeroallergens for skin prick tests in concentration 1× skin prick tests. Results: Specific IgE and skin prick tests to one or more tested aeroallergens were positive altogether in 27 patients; atopy patch tests were positive only in one of these patients. Conclusion: For atopy patch testing with aeroallergens the concentration of 1× skin prick tests is low to confirme the eczematic reaction in patients suffering from allergy to inhallant allergens.

AbstractBackgroundDermatological services in Laos, South East Asia are limited mainly to the capital and patch testing is currently not available, so no data exists regarding the common cutaneous allergens in this population.ObjectivesThe aim of this study was to document common allergens in paediatric patients with atopic dermatitis attending the allergy clinic in the capital, Vientiane.Patients/Materials/MethodsFifty paediatric patients with atopic dermatitis were patch tested using TRUE Test® panels 1 to 3 (35 allergens). Readings were taken at Days 2 and 4.ResultsTwenty-six positive patch tests were recorded on Day 4 in 15 children (30%). The most common allergens were: gold (18%), nickel (10%), formaldehyde (6%) and p-Phenylenediamine (6%). Other positive allergens were potassium dichromate (2%), cobalt dichloride (2%), Bronopol (2%), paraben mix (2%), fragrance mix 1 (2%) and neomycin (2%). The majority of the patients with positive reactions were female.ConclusionsThis study represents the first documented patch test results in the Lao population. It is hoped that these findings will help clinicians to advise the families of children with atopic dermatitis on common allergens to avoid and inform future work on contact dermatitis in this population.
