Subjects
ATOPIC dermatitis, NICKEL sulfate, CONTACT dermatitis, COBALT chloride, ALLERGENS
Abstract

Background: Atopic dermatitis (AD) and allergic contact dermatitis (ACD) are inflammatory skin conditions whose association is not clearly defined. Objectives: To identify differences in ACD profile between patients with and without AD among those referred for patch testing. Additionally, to determine the prevalence of sensitisation to standard Spanish contact allergens in both groups. Methods: We analysed two groups (AD and non‐AD) within the Spanish Registry of Research in Contact Dermatitis and Cutaneous Allergy (REIDAC). Contact allergy, clinical relevance and epidemiological data were compared between them. Results: A total of 5055 patients were included. Among them, 23% (1168) had a history or final diagnosis of AD. At least one positive reaction was seen in 468 (40%) of AD patients and 1864 (48%) of non‐AD patients. In both groups, the most common positive reactions were to nickel sulphate, methylchloroisothiazolinone/methylisothiazolinone and cobalt chloride. Age‐adjusted OR for sensitisation to nickel sulphate was 0.72 (95% CI: 0.61–0.86), indicating a decreased likelihood of sensitisation in AD patients compared to non‐AD individuals. Conclusions: We did not find an increased presence of ACD in patients with AD referred for patch testing, exhibiting similar profiles to non‐AD population, except for a negative relationship between AD and sensitisation to nickel sulphate.

Abstract

BACKGROUND: Hand eczema is common in patients with atopic dermatitis (AD), but few studies have described the characteristics of these patients in large, representative populations from different geographic regions and occupational settings. OBJECTIVE: To describe the epidemiological, clinical, and allergy profile of patients with hand eczema who underwent patch testing and compare patients with and without AD. METHODS: Analysis of data from the Spanish Contact Dermatitis Registry, a multicenter registry of patients who undergo patch testing in Spain. RESULTS: We included 1466 patients with hand eczema who were patch tested between January 2018 and June 2020. Those with AD were younger and had had symptoms for longer before testing. They were also more likely to have been exposed to occupational triggers (38% vs 53% for patients without AD). The only profession for which significant differences were found was hairdressing. The most common allergens were nickel sulfate, methylchloroisothiazolinone/methylisothiazolinone, cobalt chloride, potassium dichromate, fragrance mixes I and II, and formaldehyde. The most common diagnoses were allergic contact dermatitis (24% vs 31% in patients with and without AD, P=.0224) and irritant contact dermatitis (18% and 35% respectively, P<.001). CONCLUSIONS: AD is common in patients with predominant hand eczema who undergo patch testing. Patients with hand eczema and AD have different clinical and epidemiological characteristics to hand eczema patients in general and their final diagnosis following patch testing is also different.

Subjects

Abstract

Background Methyldibromo glutaronitrile (MDBGN) was one of the most frequent and relevant allergens found in patch testing at the beginning of this century. In 2008, this preservative was banned from cosmetics in Europe and ever since the prevalence of contact allergy to MDBGN has progressively decreased. Despite that gradual decline, MDBGN is still patch-tested in most baseline series. This study assessed the frequency of MDBGN sensitization, epidemiological characteristics of allergic patients, and the relevance of positive patch tests in a nationwide Spanish registry (REIDAC). Patients and methods We evaluated consecutively patch-tested patients in all participating centres. Using these data, we calculated the proportion of patients with positive patch tests to MDBGN from June 2018 to June 2020 and evaluated the relevance of the positive patch tests. Results One hundred and fourteen out of 5072 (2.24 %) tested patients were sensitized to MDBGN. Clinical current relevance was confirmed in only one case. Conclusion Although the frequency of contact allergy to MDBGN remains high, no clinical significance was found in most of these patients (5072 tests needed to obtain one relevant positive result). The clinical usefulness of this allergen seems weak and its continued inclusion in the European baseline series is questionable.

Abstract

Background: In 2012, a consensus was reached regarding a baseline photopatch test series on the basis of the results of a European multicentre study. Objectives: To describe experience with the European photopatch test series. Methods: A retrospective analysis of 116 patients tested with the European photopatch test series between 2014 and 2016 was performed. Results: Fifty-five positive photopatch test reactions in 25 subjects were recorded, most commonly caused by the topical non-steroidal anti-inflammatory drugs ketoprofen, dexketoprofen, and etofenomate. Organic ultraviolet (UV) absorbers constituted the second main category of agents eliciting positive photopatch test reactions. Among UV absorbers, benozophenone-3 and octocrylene were the most frequent photoallergens. UV absorbers that have been introduced more recently rarely elicited positive photopatch test reactions. Positive patch test reactions were less commonly observed than positive photopatch test reactions, namely, 21 reactions in 14 patients. Conclusions: We present the largest clinical experience with the European photopatch test baseline series hitherto reported. The results are similar to those underlying the above consensus process, reaffirming the usefulness of this series.

Abstract

Introduction: Hand eczema is a frequent disease in adults. Diagnosing the cause of hand eczema is difficult due to different classifications. There is lack of evidence on hand eczema and its causes in children. Material and method: A total of 389 children between 0 and 16 years were identified between 1996 and 2016, from whom 42 (10.8%) with exclusively hand eczema were selected. In all cases a standard battery of epicutaneous patch tests was performed, as well as additional batteries depending on the clinical suspicion. The clinical and epidemiological features of these children were recorded and compared against children with eczema in other locations. Results: The 42 children with hand eczema included 25 (60.5%) girls, and 17 (40.5%) boys, with a mean age of 10.6 +- 3.9 years, and did not differ from that of children with eczema in other locations. The definitive diagnosis after patch-testing was Atopic Dermatitis in 15 cases, Allergic Contact Dermatitis in 14 patients, Endogenous Vesiculous Eczema in 6 cases, Endogenous Hyperkeratotic Eczema in 5 cases, and Irritant Contact Dermatitis in 2 cases. The most frequent allergens detected were thiomersal (9 cases), nickel (5 cases), mercury (5 cases), and cobalt (4 cases). Conclusion: Hand eczema is a common condition in children. The most common cause is atopic dermatitis, although cases of allergic contact dermatitis manifesting as hand eczema are not uncommon. Any child with eczema of hands in whom an allergic cause is suspected should be referred for patch-testing. (C) 2017 Asociacion Espanola de Pediatria. Published by Elsevier Espana, S.L.U.

Abstract

Background/Objectives: Footwear dermatitis is a form of contact dermatitis resulting from exposure to shoes. There have been only small studies regarding foot contact dermatitis in children. The present study was undertaken to define the prevalence and epidemiologic and clinical features of shoe dermatitis in children. Methods: A retrospective study was undertaken of all children referred for patch testing between 1996 and 2015. Children with dermatitis limited to the feet were selected. Results: We collected data from 389 children younger than 16 years, 52 of whom (13.4%) were referred with dermatitis exclusively on the feet. Diagnosis after patch testing was allergic contact dermatitis in 23 children (44.2%), atopic eczema in 12 (23.1%), juvenile plantar dermatosis in 8 (15.4%), dyshidrotic eczema in 6 (11.5%), irritant contact dermatitis in 2 (3.8%), and tinea pedis in 1 (1.9%). The most frequent allergens were potassium dichromate, thimerosal, cobalt chloride, mercapto mix, colophonium, mercury, and nickel(II) sulfate. Conclusion: Allergic contact dermatitis caused by footwear is a common cause of foot dermatitis in children. Children with foot dermatitis should be referred for patch testing when an allergic origin is suspected.
