Task: Question Generation
Input (English): To investigate the role of HMG-CoA reductase inhibitor (statin) treatment during serum glucose variations on plasma oxidized LDL (ox-LDL) levels in obese patients with early Type 2 diabetes mellitus (T2D) and its relationship to endothelial biomarkers.', 'In a double-blind, randomized crossover study, 15 obese diet-treated T2D patients received cerivastatin (0.4 mg/day) or placebo for 3 months. Circulating ox-LDL levels were measured fasting and during a euglycaemic-hyperinsulinaemic clamp (approximately 5.5 mmol/l; EHC) and a hyperglycemic clamp (approximately 20 mmol/l; HC). An endothelium-dependent flow-mediated dilation (FMD) study was carried out and urinary albumin excretion (UAE) was measured at rest and during EHC. S-ICAM, s-VCAM and basal prothrombotic factors were also measured.', 'During cerivastatin treatment, basal circulating ox-LDL levels decreased by 48% (P<0.001) compared with placebo. Serum ox-LDL levels decreased during EHC and remained unchanged during HC compared with the fasting state; with cerivastatin treatment these levels were lower compared with placebo both in the fasting state and during the clamp studies. FMD was higher with cerivastatin than with placebo (P<0.001) and the increments in FMD correlated with decrements in serum ox-LDL levels (r=0.78, P=0.001). Microalbuminuria increased during EHC but this was blunted during cerivastatin therapy compared with placebo (P<0.05). Basal sICAM-1 and sVCAM-1 levels decreased (P<0.01 and P<0.05, respectively).
Output (English): Are oxidized-LDL levels changed during short-term serum glucose variations and lowered with statin treatment in early Type 2 diabetes : a study of endothelial function and microalbuminuria?
