“…Compared with previous studies, the percentage of people allergic to nickel has increased in our center over the last 10 years (from 17%) [24], despite the “nickel directive” – in force since 2005. An increase in allergies to nickel has recently been observed in the United States and other countries where there are no regulations limiting exposure to the metal [25, 26]. Allergy to nickel is observed significantly more often among women (visible in our patients), which is explained by early exposure to allergens contained in jewelry, especially earrings.…”

IntroductionThe aim of the study was to provide current data on the incidence of allergy to various contact allergens in patients with allergic contact eczema and the analysis of selected socio-demographic data of the patients.Material and methodsThe study included 1532 patients (1010 women and 522 men) treated for allergic contact dermatitis at the Department of Dermatology and Venereology and at the Dermatology Outpatient Clinic in Bialystok in 2007–2011. The assessment of selected demographic data and skin lesions was based on the MOAHFLA index, while the results of patch tests were analyzed with modified Baseline European Series consisting of 31 allergens.ResultsIn the group of patients with eczema, 34.1% were men, and 55% of all respondents were people over 40 years of age. The occupational character of skin lesions was found in 22.5%. Most frequently (38.9%) skin lesions were localized on the hands, rarely involved legs (3.98%). Atopic dermatitis was diagnosed in 4.5% of patients. The ten most frequent allergens were: nickel sulfate (24%), cobalt chloride (15.3%), fragrance mix (8.25%), potassium dichromate (6.8%), balsam of Peru (5.5%), neomycin (4.42%), paraphenylenediamine (3.85%), Quatermium-15 (2.1%), detreomycin (1.83%) and budesonide (1.44% of tested patients).ConclusionsFrequent allergy to detreomycin indicates the need of patch testing for this allergen of all examined patients with allergic contact dermatitis. The increased frequency of the nickel allergy is a worrying problem and indicates the need for education about the risk factors for nickel allergy development and the implementation of appropriate legal regulations.

“…In addition, nickel is one of the causes of allergic contact dermatitis . The prevalence of nickel‐sensitized individuals ranges from 10% to 24% . Due to its design, our study could not confirm a causal relation between endometriosis and nickel allergy; however, hypothetically, a nickel allergy could be an antecedent event to the onset of endometriosis.…”

“…In dermatitis patients, the prevalence is higher (adults, 12%‐25%; children, 5%‐30%) . Nickel allergy has been less investigated outside of Europe, although persistently high prevalences have been observed in Asia and North America . A higher prevalence of nickel allergy in individuals with atopic dermatitis has been shown in some studies, whereas others have found negative associations .…”

Nickel allergy and allergic contact dermatitis: A clinical review of immunology, epidemiology, exposure, and treatment

Nickel is the most frequent cause of contact allergy worldwide and has been studied extensively. This clinical review provides an updated overview of the epidemiology, exposure sources, methods for exposure quantification, skin deposition and penetration, immunology, diagnosis, thresholds for sensitization and elicitation, clinical pictures, prevention, and treatment. The implementation of a nickel regulation in Europe led to a decrease in the prevalence of nickel allergy, and changes in the clinical picture and disease severity. Nevertheless, the prevalences of nickel allergy in the European general population are approximately 8% to 19% in adults and 8% to 10% in children and adolescents, with a strong female predominance. Well‐known consumer items such as jewellery and metal in clothing are still the main causes of nickel allergy and dermatitis, although a wide range of items for both private and occupational use may cause dermatitis. Allergic nickel dermatitis may be localized to the nickel exposure site, be more widespread, or present as hand eczema. Today, efficient methods for exposure quantification exist, and new insights regarding associated risk factors and immunological mechanisms underlying the disease have been obtained. Nevertheless, questions remain in relation to the pathogenesis, the persistent high prevalence, and the treatment of severe cases.
