“…In the years since, it has been confirmed that, apart from FreeStyle Libre, IBOA is a contact allergen detectable in: (i) the housing [ 35 ] (1.11 ± 0.12 μg/mL), adhesive [ 35 ] (0.26 μg/mL) and in the Enlite sensor itself [ 36 ] (10 μg/sensor) (Medtronic, Fridley, MN, USA); (ii) a tubeless insulin pump Omnipod [ 37 ] (5 μg/patch and 190 μg/sensor) (Insulet Corporation, Billerica, MA, USA); (iii) insulin infusions sets Paradigm MiniMed Quick-Set and Paradigm MiniMed Sure-T [ 38 ] (Medtronic, Fridley, MN, USA); (iv) insulin infusion set Accu-Chek Insight Flex (Roche Diabetes Care, Indianapolis, IN, USA) [ 38 ]; (v) in all following parts of the Medtrum A6 TouchCare (Medtrum Technologies, Shanghai, China): 1 μg in the sensor, 3 μg in the sensor adhesive patch, 30 μg in the insulin pump reservoir, 6 μg in the reservoir patch adhesive [ 39 ]. Initially, gas-chromatography-mass-spectrometry (GC-MS) analysis showed that the related Paradigm Minimed Silhouette infusion does not contain IBOA within detection limits [ 38 ], but a recent report of a 15-year-old boy from Poland suggests that the Silhouette set might still contain IBOA in untraceable amounts, but enough to elicit contact dermatitis [ 40 ]. Unfortunately, despite the ongoing saga of skin reactions towards diabetes medical devices, it has already been reported that the relatively new insulin pump system YpsoPump (Ypsomed, Burgdorf, Switzerland) also contains IBOA, and the first cases of ACD elicited by this device are known [ 41 ].…”
