The Science: Diabetes Control The National Diabetes Education ProgramChanging the Way Diabetes is Treated.
What is Diabetes? Diabetes is a group of diseases characterized by high levels of blood glucose (blood sugar) Diabetes can lead to serious health problems and premature death About 24 million Americans have diabetes NIDDK, National Diabetes Statistics 2007. www.diabetes.niddk.nih.gov/dm/pubs/statistics/
Common Types of Diabetes Type 1 diabetes • 5% to 10% of diagnosed cases of diabetes Type 2 diabetes • 90% to 95% diagnosed cases of diabetes NIDDK, National Diabetes Statistics 2007. www.diabetes.niddk.nih.gov/dm/pubs/statistics/
Common Types of Diabetes • Gestational Diabetes occurs during pregnancy • 5 to 10 % of women with gestational diabetes are found to have type 2 diabetes • Increased lifelong risk for mother and child for developing type 2 diabetes • 40-60 % women with gestational diabetes will develop diabetes in the next 5 to 10 years NIDDK, National Diabetes Statistics 2007. www.diabetes.niddk.nih.gov/dm/pubs/statistics/
Risk Factors for Diabetes • Age 45 and older • Overweight (BMI ≥ 25) • Hypertension • Abnormal lipid levels • Family history of diabetes • Race/ethnicity • History of gestational diabetes • History of vascular disease • Signs of insulin resistance • (such as PCOS or acanthosis nigricans) • IGT or IFG on previous test • Inactive lifestyle American Diabetes Association. Diabetes Care 2008; 31;(Suppl.1):S12-54.
Diabetes and Cardiovascular Disease • Cardiovascular disease is the leading cause of death for people with diabetes • In adults with diabetes: • 68% die of heart disease or stroke • the risk for stroke is two to four times higher • 75% have high blood pressure • smoking doubles the risk for heart disease NIDDK, National Diabetes Statistics 2007. www.diabetes.niddk.nih.gov/dm/pubs/statistics/
Diabetes Complications • Diabetes is the leading cause of: • kidney failure • new cases of adult blindness • nontraumatic lower-limb amputations • In adults with diabetes: • the risk of periodontal (gum) disease is two to three times higher • 60 to 70 % have mild to severe nervous system damage NIDDK, National Diabetes Statistics 2007. www.diabetes.niddk.nih.gov/dm/pubs/statistics/
Diabetes Control and Complications Trial (DCCT) Compared effects of two diabetes treatment regimens – standard therapy and intensive control – on the complications of diabetes in people with type 1 diabetes DCCT. New England Journal of Medicine, 329(14), September 30, 1993.
DCCT Findings Glucose control is key to preventing or delaying complications of diabetes Any sustained lowering of blood glucose helps, even if the person has a history of poor control DCCT. New England Journal of Medicine, 329(14), September 30, 1993.
DCCT Findings Lowering blood glucose reduced risk of: • Eye disease by 76% • Kidney disease by 50% • Nerve disease by 60% DCCT. New England Journal of Medicine, 329(14), September 30, 1993.
United Kingdom Prospective Diabetes Study (UKPDS) Clinical Trial Looked at intensive management of blood glucose levels and long term risk-factors for diabetes complications in type 2 diabetes UKPDS. BMJ. 2000; 321:405-412.
UKPDS Findings Mirrored the findings of DCCT in people with type 2 diabetes—better glucose control reduced development of microvascular complications Demonstrated the need for management of high blood pressure and cholesterol as well as blood glucose levels (the ABCs of diabetes) UKPDS. BMJ. 2000; 321:405-412.

Epidemiology of Diabetes Interventions and Complications Study (EDIC) Observational study DCCT participants (type 1 diabetes) Looked at risk factors for long-term complications DCCT/EDIC N Engl J Med 2005: 353:2643-2653.
EDIC Findings: Intensive Therapy and Diabetes Complications • Participants continue to benefit years later from period ofintense glucose control • Years after intensive therapy: • Lasting benefits for eye, nerve, and kidney disease • Reduces CVD events by more than half DCCT/EDIC N Engl J Med 2005: 353:2643-2653.
EDIC Findings: Cardiovascular Events Cumulative Incidence of First of Any Event 0.12 0.10 Risk reduction 42% 95% CI: 9% to 63% P = 0.02 Conventional 0.08 Cumulative Incidence 0.06 0.04 Intensive 0.02 0.00 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 Years from Study Entry DCCT/EDIC N Engl J Med 2005: 353:2643-2653.
EDIC Findings: Cardiovascular Events Non-Fatal MI, Stroke, or CVD Death 0.12 0.10 Risk reduction 57% 95% CI: 12% to 79% P = 0.02 0.08 Cumulative Incidence 0.06 Conventional 0.04 0.02 Intensive 0.00 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 Years from Study Entry DCCT/EDIC N Engl J Med 2005: 353:2643-2653.
UKPDS 10 yr Follow-Up Study- insulin/sulfonylurea group Differences in A1C between intensive & standard glycemic control treatment groups were lost after one year Relative risk reductions at 10 yr in intensive insulin/sulfonylurea group: • 9% for any diabetes end point (P=0.04) • 24% microvascular disease (P=0.001) • 15% myocardial infarction (P=0.01) • 13% death from any cause (P=0.007) N Engl J Med 2008; 359
UKPDS 10 yr Follow-Up Study- metformin group Differences in A1C between intensive & standard glycemic control treatment groups were lost after one year Relative risk reductions at 10 yr in intensive metformin group: • 21% for any diabetes end point (P=0.01) • 33% myocardial infarction (P=0.005) • 21% death from any cause (P=0.002) N Engl J Med 2008; 359
UKPDS 10 yr Follow-Up Study- Blood Pressure findings Between group differences lost within 2 yrs Significant relative risk reductions in tight control group were not maintained Benefits of BP control do not extend beyond intensive therapy period & ongoing treatment is essential N Engl J Med 2008; 359
Recent Clinical Trial Findings: Intensive glucose control in type 2 diabetes: • lowers risk of new or worsening microvascular complications (ADVANCE) • was associated with increased mortality in patients with longstanding DM and known CVD (ACCORD) • increases risk of severe hypoglycemia (ADVANCE, ACCORD and VADT) ACCORD: N Engl J Med 2008; 358(24):2545-59 ADVANCE: N Engl J Med 2008; 358 (24): 2560-72 VADT: J Diabetes Complications 2003; 17 (6): 314-22
Key points of recent findings: • Intensive glucose control in newly diagnosed type 1 or type 2 diabetes has benefits during intensive therapy AND a legacy effect for later micro- and macrovascular benefits • Optimal glucose management should start as early as possible & continue as long as possible • While the A1C goal for the general population is <7%, treatment must be individualized. N Engl J Med 2008; 359
SEARCH For Diabetes in Youth Study Observational study Physician-diagnosed diabetes in youth ages 0-19 Data will help researchers better understand and treat diabetes in young people (SEARCH). Diabetes Care 2006 29(8): 1891-6.
