“…Our prevalences of contact allergy to MI are higher than reported elsewhere, with a peak of 20.3% of those patch tested in 2015. In contrast, the prevalence of MI allergy in the United States was 10.9% in 2013 to 2014 . In Leeds, United Kingdom, MI allergy increased from ∼1% in 2009 to ∼10% in 2014, and decreased to 4% in 2015 .…”

“…Cobalt is a strong skin sensitizer, and an estimated 5.9% and 7.4% of patch tested dermatitis patients in Europe and North America, respectively, are cobalt‐allergic . However, clinical relevance is often difficult to determine, and previous identification of occupational and consumer sources of cobalt seems to be insufficient.…”

Background Cobalt contact allergy is common, but clinical relevance is often difficult to determine. Objectives To examine the aetiology, prevalence and clinical characteristics of cobalt‐allergic patients who were patch tested between 2002 and 2017 at the Department of Dermatology and Allergy, Herlev‐Gentofte Hospital. Methods Patch test data, along with patient characteristics and causative exposures, from all adult dermatitis patients seen and tested between 2002 and 2017 were analysed. Associations were tested with the χ 2 test and logistic regression. Results A total of 13 475 adults aged 18 to 99 years were patch tested. The overall prevalence of cobalt allergy and the prevalence of isolated cobalt allergy were 3.3% and 1.5%, respectively. The prevalence of isolated cobalt allergy decreased from 2.4% in 2006 to 2009 to 1.1% in 2014 to 2017 (Ptrend = 0.00003). Leather exposure as a relevant cause of allergic cobalt dermatitis increased from 3.7% in 2002 to 2009 to 8.3% in 2010 to 2017 (P = 0.04). The current clinical relevance of positive patch test reactions, that is, a positive reaction to cobalt combined with a history of current skin exposure to a source of cobalt, was 20.1%. Conclusions We conclude that cobalt allergy is relatively common, but causative exposures are largely unknown, and the proportion of positive patch test reactions with clinical relevance is low. It is therefore currently unclear how we can better protect consumers and workers from cobalt exposure.

“…Since the first cases of ACD were described in 2003, there has been a slow but steady increase in the frequency of sensitization. The North American Contact Dermatitis Group, for instance, which has been routinely patch testing patients with decyl glucoside since 2009, noted an increase in positive reactions from 1.5% in 2009 to 2012 to 1.7% in 2013 to 2014 . Routine patch testing with multiple alkyl glucosides has not been yet widely adopted.…”

Patch testing with alkyl glucosides: Concomitant reactions are common but not ubiquitous

Background Alkyl glucosides contitute a family of mild surfactants that are increasingly being used in a wide range of cosmetics and household products. Contact allergy to alkyl glucosides may be more frequent than previously suspected, especially in atopic patients. Objectives To investigate the frequency of contact allergy to alkyl glucosides, and to identify concomitant reactivity. Method We retrospectively reviewed all cases of suspected allergic contact dermatitis (ACD) in which patients were patch tested with either a cosmetic series that includes five alkyl glucosides (decyl glucoside, lauryl glucoside, coco glucoside, cetearyl glucoside, and caprylyl/capryl glucoside) or a specific alkyl glucoside series from November 2013 to April 2017 in two UK centres. Results A total of 5775 patients were patch tested across the two centres. Twenty‐nine (1.04%) of the 2796 patients tested with the cosmetic/alkyl glucoside series had a positive patch test reaction to at least one of the alkyl glucosides. Twenty‐three (79.3%) patients were sensitized to multiple alkyl glucosides; 21 patients (72.4%) were female. The mean age was 43.5 years. Twelve patients (41.4%) had a background of atopic dermatitis. Conclusions The prevalence of alkyl glucoside‐induced ACD is relatively high, and there are frequent concomitant reactions between different alkyl glucosides. We recommend the inclusion of alkyl glucosides in all cosmetic series.
