NCT00370305

Brief Summary

The purpose of this study is to determine whether the insulin sensitizing effects of rosiglitazone were accompanied by changes in 11ß-HSD1 expression and activity in different tissues. Furthermore the metabolic and hormonal effects of PPAR gamma stimulation by rosiglitazone will be analysed in several tissues.

Outcome Measures

Primary Outcomes (3)

  • changes of 11ß-HSD1 expression in adipose tissue and skeletal muscle during 8 weeks of rosiglitazone treatment

    11ß-HSD1 expression will be measured in adipose tissue and skeletal muscle

    8 weeks

  • changes of hepatic 11ß-HSD1 activity during 8 weeks of rosiglitazone treatment

    11ß-HSD1 activity will be assessed by measuring conversion of cortisone to cortisol (ratio will be calculated)

    8 weeks

  • changes of whole body 11ß-HSD1 activity during 8 weeks of rosiglitazone treatment

    whole body 11ß-HSD1 activity will be assessed by measuring the ratio of urinary tetrahydrocortisol (THF) + alpha-tetrahydrocortisol (THF) / tetrahydrocortisone

    8 weeks

Secondary Outcomes (6)

  • changes in insulin sensitivity during 8 weeks of rosiglitazone treatment

    8 weeks

  • Hormonal and metabolic changes induced by the intervention

    3 months

  • changes of FGF-21 induced by the intervention

    8 weeks

  • changes of free fatty acids (FFA) induced by the intervention

    8 weeks

  • changes of myocellular SCD1 expression induced by the intervention

    8 weeks

  • +1 more secondary outcomes
