A summary of published reports that have compared the magnitude of sensor lag measured during rising glucose (or low insulin effect) to lag measured during falling glucose (or high insulin effect)
Authors, year | Reference | Type of sensor | Subjects | Lower lag found during high insulin effect? |
---|---|---|---|---|
Sternberg et al., 1996 | [3] | Microdialysis | Type 1 diabetes— humans | Yes, but only in ~50% of subjects |
Thome-Duret et al., 1996 | [4] | Wilson-Reach sensor(GOX, non-mediated) | Type 1 diabetes—rats | Yes |
Wilhelm et al., 2006 | [21] | MiniMed (GOX, non-mediated) | Type 1 diabetes— humans | * |
Schmidke et al., 1998 | [7] | Heller sensor (GOX, osmium-mediated) | Non-diabetic rats | No |
Aussedat et al., 2000 | [5] | Wilson-Reach | Non-diabetic rats | Yes |
Rebrin et al., 1999 | [8] | MiniMed | Non-diabetic dogs | No |
Kulcu et al., 2003 | [6] | Cygnus, GOX, transdermal | Type 1 and Type 2 diabetes— humans | Yes |
Boyne et al., 2003 | [2] | MiniMed | Type 1 diabetes— humans | No |
Kamath et al., 2009 | [12] | Dexcom Seven+ (GOX, non-mediated) | Type 1diabetes— humans | Apparently yes, although not directly stated |
Compared with the rising glucose phase, during rapid decline after oral glucose and insulin administration, there was less of a lag of the sensor (vs. capillary blood as a reference), but there was also consistent calibration error (the sensor substantially underestimated blood glucose at high glucose levels), so this finding is difficult to interpret.
GOX, glucose oxidase.
