The implanted glucose monitoring system Eversense: An alternative for diabetes patients with isobornyl acrylate allergy.

BACKGROUND: Some patients with diabetes develop skin reactions when using systems for continuous glucose monitoring (CGM) or insulin pumps. Regular usage and long wearing periods lead not only to skin irritation, but also to allergic contact dermatitis. It has been shown that allergens such as isobornyl acrylate (IBOA) are present in the plastic housing and also in the adhesives of medical devices used for diabetes treatment. OBJECTIVES: To evaluate the IBOA content of all parts of a newly introduced, implanted CGM system (Eversense) to check whether this can be an alternative for IBOA-sensitized patients. METHODS: The IBOA content of the implanted sensor itself (n = 3), the transmitter (n = 3), and two different types of adhesive (white adhesive [n = 4] and clear adhesive [n = 4]) was measured by gas chromatography/mass spectrometry. RESULTS: No IBOA was found in any part of this CGM system. CONCLUSIONS: Patients with an IBOA allergy may be able to use this implanted CGM system.
