Summary
Diabetes prevalence and costs continue to grow
Lower treatment targets will likely drive the adoption of more
intensive management
The use of intensive insulin management continues to grow
with a notable increase in insulin pump use
A potential barrier to intensive management is patient’s lack
of awareness and perception of good control

Editor's Notes

  • #6 Lowering HbA1C Reduces Risk of Complications United Kingdom Prospective Diabetes Study (UKPDS) UKPDS, the largest and longest study of the benefits of tight glycemic control in patients with type 2 diabetes, has demonstrated that improved glucose control in patients with type 2 diabetes reduces the risk of developing retinopathy, nephropathy, and possibly neuropathy. In the UKPDS, newly diagnosed patients with type 2 diabetes were assigned either to conventional or intensive therapy. Conventional therapy began with dietary intervention, with the goal of therapy to maintain fasting plasma glucose below 270 mg/dL. If marked hyperglycemia or symptoms occurred, patients were secondarily randomized to treatment with sulfonylurea or insulin therapy, with the additional option of metformin in overweight patients. For those assigned to intensive therapy, the goal was to maintain a FPG <108 mg/dL. Non-overweight patients were randomly assigned to treatment with a sulfonylurea or insulin. Overweight patients were randomly assigned to one of the above options or metformin. Overall, the risk of any diabetes-related endpoint was reduced by 12% and the microvascular complications rate decreased by 25% in patients receiving intensive therapy. UKPDS. Lancet. 1998;352:837-853. Epidemiologic analysis showed a continuous relationship between the risk of microvascular complications and glycemia, suggesting that for every percentage point decrease in HbA1c there was a 35% reduction in the risk of microvascular complications. Matthews DR, et al. ADA. 1999, Abstract 0669.
  • #7 Goals of Intensive Diabetes Management glucose hypothesis: people without diabetes do not get diabetic complications achieving euglycemia is a means to and end: The end point of therapy is by normalization of glucose to prevent the occurrence of complications universally accepted due to irrefutable prospective studies studies demonstrated that glycemic control is both attainable and beneficial factors preventing this from being actualized hypoglycemia hyperglycemia DKA quality of life of the individual must be maintained throughout the therapy REF: ADA: Clinical Practice Recommendations, 2001.  
  • #13 Slide Index 00030 DISCUSSION POINTS: Click 1: DCCT and EDIC data in left panel: Left panel shows data from a sub-group of patients who had been in the intensive group during the DCCT and continued in EDIC, a long-term follow-up of the DCCT This sub-group began the DCCT with an average HbA1c of 9.0% [first bar], and ended the study with a mean of 7.3% [second bar]. After the DCCT ended, patients returned to community-based diabetes management and were followed for an additional 4 [third bar, blue] and 6 [last bar, blue] years. As can be seen by the increasing HbA1c in the last 2 blue bars, these patients had difficulty sustaining HbA1c improvements achieved during the DCCT. Click 2: UKPDS data appears in right panel The right panel shows data from the insulin-treated group of the UKPDS. Initial decreases in HbA1c were not sustained during the 10-year study period. SLIDE BACKGROUND: EDIC: Epidemiology of Diabetes Interventions and Complications 1375 of the 1441 DCCT participants (95%) volunteered to participate in EDIC. 1208 patients were evaluated after 4 years of follow-up in EDIC (605 of these were previously in the DCCT intensive group; N for Year 6 not yet available). Data for DCCT/EDIC on slide are for previous participants in DCCT intensive group. The gap between this group and their counterparts in the conventional group has diminished over time. Data for previous participants in DCCT conventional group are: DCCT time 0 = 9.0% DCCT time 6.5 yrs = 9.0% EDIC + 4 years = 8.2% EDIC + 6 years = 8.1% Data for DCCT/EDIC are means.
  • #14 Relationship Between %BG in Target and HbA1c Level Brewer at the Barbara Davis Center in Denver, Colorado effort to determine the percentage of SMBGs within, above or below target range that result in HbA1c levels within target range = 70 to 180 mg/dl above target range = greater than 180 mg/dl below target range = below 70 mg/dl a slight difference needs to be achieved of BG within target range to achieve a reduction of HbA1c 8.5% to 7%. slight improvements yield large results! Note: at all HbA1c levels the occurrence of hypoglycemic values is in excess of 10%. REF: Brewer K, Chase P, Owen S, Garg S, Diabetes Care 1998, 21:2.
  • #15 Key Points The primary objectives of effective diabetes management are to reduce A1C to as near-normal levels (ie, 4%–6%) as is possible and safe, to lower systolic blood pressure to <130 mm Hg, and to decrease LDL cholesterol to <100 mg/dL Achieving target levels of A1C, systolic blood pressure, and LDL cholesterol may reduce the risk of the micro- and macrovascular complications of diabetes by up to 75% As illustrated in this slide, the objectives of effective diabetes management are to reduce A1C to as near-normal levels as is possible and safe (ie, 4%–6%), lower systolic blood pressure to <130 mm Hg, and to decrease LDL cholesterol to <100 mg/dL. Evidence suggests that achieving these target levels can reduce the risk of both microvascular and macrovascular complications of diabetes by >75%.1 Most recently, the Steno-2 Study followed 160 patients with type 2 diabetes and microalbuminuria over 7.8 years to determine the effect of intensive treatment on long-term CV and microvascular outcomes. Researchers found that target-driven, intensive treatment consisting of stepwise diet, exercise, and pharmacotherapy for glycemia, microalbuminuria, lipids, and blood pressure resulted in a decreased risk of CV and microvascular events of about 50%. Control group members received conventional treatment in accordance with national guidelines. However, factors leading to diminished degrees of separation between the intensive treatment and control groups (eg, more than 50% of control group members were referred for specialist treatment during the course of the study) led the authors to estimate that the actual risk reduction associated with intensive versus conventional therapy may be even greater than that observed.2 References American Diabetes Association.
