Dr BG will have fun with this one when she gets the full text, but here's the sneak preview from the abstract she forwarded to me:
"In patients with IFG and hyperlipidaemia, rosuvastatin treatment was associated with a dose-dependent increase in insulin resistance."
That's an increase of 46% in the fasting insulin needed to maintain some semblance of no-worse-than-modest fasting hyperglycaemia. And probably wall to wall sdLDL in whatever cholesterol you have left.
IFG is just a random category on the road to diabetes. If you think rosuvastatin does any good to the insulin sensitivity of people with frank diabetes or of "normal" people who have yet to get themselves a label, I suspect you will be disappointed! But then what's a bit of extra insulin, sugar or both when you can have lipids to die for...
