High Prevalence of Nickel Allergy in an Overweight Female Population: A Pilot Observational Analysis
CONTEXT In our Allergy Unit, we incidentally observed that a low Nickel diet, prescribed for delayed allergy to Nickel sulfate, reduced body mass index (BMI) and waist circumference in overweight patients. OBJECTIVES This pilot cross-sectional analysis was undertaken to compare the prevalence of Nickel allergy of overweight individuals versus the general population. We also had the chance to ...
Fig. 1. Allergic nickel dermatitis caused by nickel release from an electric shaver. Nickel allergy is frequent in adult Danes and dermatitis patients (1, 2). The high prevalence is mostly explained by consumer exposure to products that release nickel, e.g. watches, jewellery, buttons, zips, rivets and mobile phones (3–8). It has been debated whether classic dry electric shavers may cause nicke...
BACKGROUND To estimate the prevalence of nickel allergy, self-reports are sometimes used in epidemiological studies. Self-reports are practical and may facilitate estimation of prevalence provided that the questions are validated. OBJECTIVES To investigate the validity of self-reported nickel allergy. METHODS Three hundred and sixty-nine women, aged 30-40 years, from the general population ...
This study was performed to establish a convenient mouse model for the evaluation of nickel allergy. For sensitization, 0.2 g of nickel sulfate in petrolatum was applied 4 times every other day to the shaved dorsal skin. Seven days after the first application of the nickel sulfate salt sample, the antigen-specific metal allergy reaction was estimated based on the swelling response of the footpa...

Potential relationships between the development of nickel allergy and previous ear piercing or orthodontic treatment with nickel-containing appliances were studied in 294 patients. We found 77 (31.2%) of 247 patients with pierced ears were allergic to nickel compared to only three (6.4%) patients without pierced ears (p = 0.001), which confirms earlier suggestions that nickel allergy (as assess...
