The UKPDS: implications for the dyslipidaemic patient.

The UK Prospective Diabetes Study (UKPDS) is the largest intervention trial to date of patients with type 2 diabetes, involving 5102 newly diagnosed diabetic patients. Results showed that 59% of patient deaths were from cardiovascular disease. While intensive treatment of glucose produced a significant 25% reduction in microvascular endpoints compared with diet only (p=0.0099), patients with type 2 diabetes usually have a lipid profile that is highly atherogenic. In the UKPDS, intensive treatment of hyperglycaemia and hypertension did not improve lipid levels. In patients without diabetes, lipid-lowering therapy has been shown to reduce the risk of cardiovascular events in both primary and secondary prevention trials. Currently, a number of large-scale trials of lipid-lowering therapy in patients with diabetes are ongoing. For example, the Lipids in Diabetes Study will determine whether lipid lowering with a statin or fibrate can substantially reduce cardiovascular morbidity and mortality in 5000 patients with type 2 diabetes. The Atorvastatin Study for the Prevention of coronary heart disease ENdpoints (ASPEN) is comparing double-blind treatment with atorvastatin and placebo in 2250 US diabetic patients without coronary heart disease, while a sister trial in the UK, the Collaborative AtoRvastatin Diabetes Study (CARDS), is enrolling 1820 diabetic patients. The results from these trials may provide information that which will help determine the future management of diabetic dyslipidaemia.
