Description
Summary:Van Walraven highlights the United Kingdom Prospective Diabetes Study (UKPDS). The study showed that attaining intensive glucose control in patients with newly diagnosed type 2 diabetes with metformin, sulfonylureas or insulin significantly decreased microvascular complication risks despite a small difference in glycosylated hemoglobin (HbA1c) of only 0.9% between treatment groups. In addition, the study showed that metformin significantly decreased all-cause mortality in those with obesity. Posttrial analyses of UKPDS found that intensive control by any treatment significantly decreased risks of diabetes-related outcomes, myocardial infarction and all-cause mortality. These results were attained despite identical HbA1c levels between treatment groups during posttrial monitoring. The Action to Control Cardiovascular Risk in Diabetes and Action in Diabetes and Vascular Disease: Preterax Diamicron Modified release Controlled Evaluation randomized controlled trials (both subsequently showed that intensive glucose control significantly decreased microvascular disease in those with long-standing type 2 diabetes. This research highlights the importance of good glucose control in the treatment of type 2 diabetes.
