During the past 8 years, a large number of reports have appeared on allergic contact dermatitis to glucose sensors and insulin pumps in paediatric and adult patients with type 1 diabetes mellitus. Isobornyl acrylate in one particular sensor sensitised many hundreds of (published) individuals, and many other allergens were discovered in a large number of sensors and pumps. Diagnostic procedures with patch tests proved very complicated, as manufacturers showed a serious lack of cooperation with dermatologists in providing information on the ingredients of their products and samples for patch testing. This two-part article provides a full and detailed review of all aspects of the subject of allergic contact dermatitis to glucose sensors and insulin pumps. Part 1 begins with a general introduction to sensors and pumps, followed by the cutaneous adverse reactions that they have caused and a full account of the allergens in the diabetes devices. In addition, an overview of the glucose sensors and insulin pumps that have caused allergic contact dermatitis is presented. Part 2 presents all published case reports and case series, clinical features of allergic contact dermatitis to sensors and pumps, patch test procedures, differentiation from irritant dermatitis, management of allergic patients and (proposed) legislation.
