Systemic contact dermatitis after oral exposure to nickel: a review with a modified meta‐analysis

2006

Systemic contact dermatitis can be elicited experimentally in nickel-sensitive individuals by oral nickel exposure. A crucial point interpreting such experiments has been the relevance of nickel exposure from drinking water and diet. The aim of this meta-analysis study on former nickelexposure investigations was to provide the best possible estimation of threshold values of nickel doses that may cause systemic contact dermatitis in nickel-sensitive patients. 17 relevant investigations were identified, and statistical analyses were performed in a stepwise procedure. 9 studies were included in the final dose-response analysis, which divided the studies into a homogenous middle group of 5 studies and 2 groups of 2 studies with a higher and lower response frequency, respectively, described by logistic dose-response curves shifted in parallel. On the basis of these curves, calculations were made of the doses that, theoretically, would cause systemic contact dermatitis in exposed nickel-sensitive patients. The results from the 2 most sensitive groups show that 1% of these individuals may react with systemic contact dermatitis at normal daily nickel exposure from drinking water and diet, i.e. 0.22-0.35 mg nickel.

“…In Netherland, the Cr concentration in 76% of the supplies was below 1 μg/L and of 98% below 2 μg/L [20]. A survey of Canadian drinking-water supplies gave an overall median level of Cr as 2 μg/L, with maxima of 14 μg/L (raw water) and 9 μg/L (treated water) [21]. Cocho et al reported that normal cow milk contains 5-15 μg/L of Cr [22].…”

The concentration of selected heavy metals (chromium and zinc) was detected and estimated in water and raw milk collected from Chittagong City of Bangladesh. A total of 25 water samples and 20 raw milk samples were collected from different farms situated in 10 locations of Chittagong, Bangladesh. Chromium content in water was obtained in the range from 0.2 µg/L to 13 µg/L. The highest level of chromium content in water was 13.068 µg/L. The content of chromium in raw milk was obtained in the range from 2 µg/L to 17 µg/L. The highest level of chromium in milk was 17.062 µg/L. Chromium concentrations in water and milk were below the maximum allowed limit. The concentration of zinc in water was in the range from 0.01 mg/L to 1 mg/L. The highest level of zinc in water was 1.024 mg/L. The concentration of zinc in raw milk was in the range from 0.6 mg/L to 0.9 mg/L. The highest concentration of zinc in water was 1.024 mg/L which is around the toxicological guidance value of zinc.

“…Exposure of cobalt from water varies considerably from location to location but median cobalt concentration in USA drinking water is <2.0 μg/L [11]. For example, in Canada, the daily cobalt intake of the average adult form drinking water is ≤ 2.6 μg; this could increase to 10 μg for those living in areas with the highest cobalt levels [12][13][14][15][16][17][18][19] (Table 1). Occupational exposure to cobalt can result from metal mining, smelting, refining, in industries that make or use cutting or grinding tools, or in other industries that produce or use cobalt metal and cobalt compounds.…”

Cobalt is a chemical element that has been used for centuries recreationally as pigments for colouring, giving the bluish hue to glass. Cobalt Poisoning can be manifested by a wide array of systemic effects. Cobalt poisoning can be seen as a result of super alloys in orthopaedic implants, ionizing radiation, occupational exposure and rarely as a foam stabilizer in beer. Here in we conduct a review of the literature describing the systemic adverse effects of cobalt poisoning along with the respective toxicity levels that have been attributed to multisystem pathology.
