Phielix et al.: Hepatic Fat Content and Adipokines
Thiazoledinediones decrease blood glucose by their insulin-sensitizing properties. Here the investigators examined whether pioglitazone (PIO) improves insulin sensitivity independently of glycemic control and whether adipokines or non-esterfied fatty acids (NEFA) serve as mediators.

- whole body insulin sensitivity [ Time Frame: within a minimal of 1 week before the start of the 12 weeks pioglitazone or glimepiride treatment and after the last day of the treatment period. ] [ Designated as safety issue: No ]Participants underwent a two-step hyperinsulinemic euglycemic clamp to determine insulin sensitivity, expressed as rate of glucose disposal (Rd) in mg/kg/min.
- intrahepatocellular lipid content [ Time Frame: within a minimal of 1 week before the start of the 12 weeks pioglitazone or glimepiride treatment and after the last day of the treatment period. ] [ Designated as safety issue: No ]Liver proton-magnetic resonance spectroscopy was applied to determine liver fat (HCL) in % (relative to the water peak).
