NCT01570660

Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

  • whole body insulin sensitivity

    Participants underwent a two-step hyperinsulinemic euglycemic clamp to determine insulin sensitivity, expressed as rate of glucose disposal (Rd) in mg/kg/min.

    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.

Secondary Outcomes (1)

  • intrahepatocellular lipid content

    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.

Study Arms (1)
