Study Overview In a post hoc analysis of the Treating to New Targets study, high-density lipoprotein cholesterol levels in patients receiving statin therapy were shown to be predictive of subsequent major cardiovascular events, even when low- density lipoprotein (LDL) cholesterol levels were taken into account and even among patients with very low levels of LDL cholesterol (<70 mg per deciliter)

Relationship between HDL Cholesterol Levels and the Risk of Major Cardiovascular Events Barter P et al. N Engl J Med 2007;357:

Conclusion In this post hoc analysis, HDL cholesterol levels were predictive of major cardiovascular events in patients treated with statins This relationship was also observed among patients with LDL cholesterol levels below 70 mg per deciliter

Original Article Addition of Biphasic, Prandial, or Basal Insulin to Oral Therapy in Type 2 Diabetes Rury R. Holman, M.B., Ch.B., F.R.C.P., Kerensa I. Thorne, M.Sc., Andrew J. Farmer, D.M., F.R.C.G.P., Melanie J. Davies, M.D., F.R.C.P., Joanne F. Keenan, B.A., Sanjoy Paul, Ph.D., Jonathan C. Levy, M.D., F.R.C.P., for the 4-T Study Group N Engl J Med Volume 357(17): October 25, 2007

Study Overview In an open-label trial, patients with type 2 diabetes with a suboptimal glycated hemoglobin level while receiving a maximally tolerated dose of metformin and sulfonylurea were randomly assigned to receive biphasic, prandial, or basal insulin The addition of a single analogue-insulin formulation resulted in a glycated hemoglobin level of 6.5% or less in a minority of patients at 1 year. Regimens of biphasic or prandial insulin had greater efficacy than did the basal regimen but were associated with greater risks of hypoglycemia and weight gain

Adverse Events Holman RR et al. N Engl J Med 2007;357:

Conclusion A single analogue-insulin formulation added to metformin and sulfonylurea resulted in a glycated hemoglobin level of 6.5% or less in a minority of patients at 1 year. The addition of biphasic or prandial insulin aspart reduced levels more than the addition of basal insulin detemir but was associated with greater risks of hypoglycemia and weight gain
