Evaluation of the correlation between the spectra of volatile organic compounds (VOCs), measured with GC-IMS and MOx sensors, and the venous blood glucose level in individuals with type 2 diabetes
Zusammenfassung der Studie
The main objective of this study is to identify certain particles in the exhaled air that are associated with different blood glucose levels. Highly specialized breath analysis devices are used to accurately measure the composition of the exhaled air. These measurement results are then compared with the blood glucose levels of participants with type 2 diabetes. Participants complete five visits, during which four visits involve different glucose trajectories (increasing and decreasing) through the administration of liquid sugar (to raise the level) and insulin (to lower the level). During these visits, blood glucose values and the composition of the exhaled air are regularly recorded. The study examines both differences between individual visits of the same person and between different participants. It analyzes how quickly changes in blood glucose can be detected in the exhaled air, how different rates of blood glucose change affect the results, and whether it makes a difference if participants have eaten or if liquid sugar has been administered. Each visit includes monitoring of vital signs, safety checks, and recording of blood glucose values and exhaled air data. The study spans ten months, includes 15 participants, and is scheduled to be conducted from June 2024 to March 2025.
