Implications of the UK prospective diabetes study: questions answered and issues remaining.

摘要

The UK Prospective Diabetes Study (UKPDS) provides the first conclusive proof for the importance of intensifying diabetes control in individuals with type 2 diabetes mellitus. However, reduction in cardiovascular disease risk with intensive therapy was modest and did not reach statistical significance. Metformin therapy in obese individuals with type 2 diabetes mellitus was associated with reduced cardiovascular death. These observations should be re-evaluated to determine whether various therapeutic agents available for treatment of type 2 diabetes mellitus have different effects on cardiovascular complications of diabetes. The addition of alpha-glucosidase inhibitor, acarbose, improved glycaemic control irrespective of concomitant therapy for diabetes, although compliance with this agent was poor. The tight blood pressure control study embedded in UKPDS reaffirms the importance of lowering the blood pressure below 150/85 to reduce microvascular and macrovascular complications of diabetes.
