28 Recommendations To achieve glycemic targets in adults with type 1 diabetes, basalbolus insulin regimens or the use of CSII as part of an intensive diabetes management regimen should be used [Grade A, Level 1A] 2. Rapid-acting insulin analogues, in combination with adequate basal insulin, should be used instead of regular insulin, to minimize the occurrence of hypoglycemia, improve A1C [Grade B, Level 2] and achieve postprandial glucose targets [Grade B, Level 2] 3. Rapid acting insulin analogues (aspart or lispro) should be used with CSII in adults with type 1 diabetes [Grade B, Level 2] CDA CPGs. Can J Diabetes 2013;37:S56-60 guidelines.diabetes.ca BANTING ( ) diabetes.ca Copyright 2013 Canadian Diabetes Association

29 Recommendations 4 and 5 4. A long-acting insulin analogue (detemir, glargine) may be used as the basal insulin [Grade B, Level 2] to reduce the risk of hypoglycemia [Grade B, Level 2], for detemir; [Grade C, Level 3], for glargine], including nocturnal hypoglycemia [(Grade B, Level 2), for detemir ;(Grade D, Consensus), for glargine]. 5. All individuals with type 1 diabetes should be counseled about the risk and prevention of insulin-induced hypoglycemia, and risk factors for severe hypoglycemia should be identified and addressed [Grade D, Consensus] CDA CPGs.

54 4T Study: Insulin Initiation - Results Mean A1C levels achieved were similar: 7.1% biphasic, 6.8% prandial, 6.9% basal Hypoglycemia rates (per patient per year) lowest in basal group (1.7%), biphasic group (3.0%), prandial group (5.7%) Mean weight gain highest in the prandial group The authors concluded that basal insulin had better control, less hypoglycemia, and less weight gain Holman RR et al.

68 Insulin Degludec: Summary Through the formation of multihexamer chains of insulin in subcutaneous depots, degludec has an extra long duration of action (half-life >25 hours and activity > 40 hours) Insulin degludec effectively improves A1C and is noninferior to insulin glargine in bolus and basal-bolus therapy in both type 1 and type 2 diabetes Insulin degludec results in significantly less risk of hypoglycemia than insulin glargine 20% less risk of overall confirmed hypoglycemia 25% less risk of nocturnal hypoglycemia Degludec improves the quality of life of people with diabetes who require insulin therapy Heller S et al. Lancet 2012;379: Garber AJ et al. Lancet 2012;379:

69 Key Messages on Insulin Therapy Individuals must strive for self management of their diabetes Self management of insulin: individuals need to be proactive and less reactive Need to adjust insulin doses to reach the next upcoming target Patients should ask themselves: should I take more or less insulin with this injection?

70 Glycemic Management of Diabetes 2013 CDA guidelines recommend that glycemic management should be individualized, aiming for A1C 7% for most people Basal-bolus insulin therapy are the insulin regimens of choice for all adults with type 1 diabetes Metformin is the initial choice for type 2 diabetes, with additional antihyperglycemic agents selected on the basis of matching individuals with drug characteristics Metformin, incretin-based therapies and acarbose, are not associated with adverse CV outcomes Analogues should be considered instead of human insulin to improve A1C while minimizing the occurrence of hypoglycemia All individuals with diabetes should be counseled about the risk, prevention and treatment of hypoglycemia CDA CPGs.
