Allergic contact dermatitis from glucose sensors may interfere with their ongoing application.
To evaluate a series of Spanish patients with contact dermatitis to glucose sensors regarding former sources of contact allergens, patch test results and outcomes from the ongoing use of the device.
A series of patients with contact dermatitis from glucose sensors was investigated in eight dermatology departments across Spain epidemiologic features, brands, latency time to develop dermatitis, the ability to continue using the devices as well as the patch test results.
Thirty patients were evaluated mean age: . years. . % were children and . % female. . % used Freestyle Libre FSL. / . % reacted to isobornyl acrylate IBOA and / . % to N,N dimethylacrylamide DMAA. The mean latency time to develop dermatitis was months. / . % patients continued using the same sensor causing the reaction. / . % were unable to continue using the sensor due to severe reactions. Of them, were positive to IBOA, one to IBOA and DMAA; one to DMAA; one to colophony and to isopropyl alcohol wipes. In one patient the outcome was unknown.
The frequency of sensitization to IBOA and DMAA, was lower than in other European series, but similar to a previously published Spanish article. Legislation requiring manufacturers to provide information regarding medical devices composition and cooperate with the investigation of contact dermatitis is urgently needed.
