Medical Guidelines for the Management of Diabetes Mellitus. Endocr Pract. 2002; 8(Suppl. 1): A1C (%) Normal: 4-6% Fasting/Preprandial (mg/dL) (plasma equivalent) Postprandial (mg/dL) (2-hour) ACE <6.5 <110 <140 ADA < <180* * Peak Goals for individual patients may vary. Aim for the Lowest A1C Possible without Hypoglycemia. Targets for Glycemic Control

Relative Contribution of FBG and PPG Varies With A1C Range Adapted from Monnier L, et al. Diabetes Care. 2003;26: Thus, to get to glycemic goals, one must control PPG as well as FBS. (incretins, alpha-glucosidase inhibitors, TZDs, glinides, fast-insulin analogues) Inc PPG increases Micro- and macro- vascular disease

Non-Insulin Therapy for Type II Diabetes

Non-Insulin Therapy for Hyperglycemia in Type 2 Diabetes, Treating Defronzo’s Octet: Match Patient Characteristics to Drug Characteristics 5. Gut CHO Absorption: Incretin, Pramlintide, Glucosidase inh. Peripheral glucose uptake Pancreatic insulin Secretion: Incretin, ranolazine 2.Pancreatic glucagon Secretion- Incretin HYPERGLYCEMIA 6.Fat- TZD, metformin 7.Brain- TZD,INCRETIN, bromocryptine 8.Kidney- SGLT2 3. Muscle- TZD, Incretin 4.Liver Hepatic glucose production: Metformin, incretin De

The New ADA Guidelines for Type 2 Diabetes: AKA- David Nathan’s Regimen- DNR Revised Treatment Algorithm Intensive insulin At diagnosis: Lifestyle + metformin At diagnosis: Lifestyle + metformin STEP 1 STEP 2 Tier 1*Tier 2 † STEP 3 Add basal insulin Add sulfonylurea Add GLP-1 agonist Add pioglitazone ± SU HbA1C >7.0% NOT Glyburide, chlorpropamide NOT Rosiglitazone

Endocr Pract. 2009;15: A1C 6.5%-7.5%A1C 7.6%-9.0% A1C > 9.0% If under treatment If drug naive Insulin plus other agent(s)* Insulin plus other agent(s)* Symptoms No symptoms Lifestyle Modifications *Pramlintide can be used with prandial insulin, but insulin secretagogues should be discontinued with multidose insulin Monotherapy Dual therapy Triple therapy Dual therapy Triple therapy Therapeutic Choice, based on Safety/ Efficacy, Should Match The Drug Characteristics With Patient Characteristics

Minimize risk/severity of Hypoglycemia5. Lifestyle Modification Essential and NO SMOKING 2. Minimize risk/severity of Weight gain 6. Combination frequently required; Complimentary mechanisms of action 3. Fast therapeutic changes (2-3 months, earlier even better) 7. When using insulin, add an insulin-sensitizing agent if possible 4. Address fasting and postprandial glucose8. Cost is important but, safety and efficacy trump cost Future AACE Guideline- Modest Proposal Therapeutic Choice Should Match The Drug Characteristics With Patient Characteristics Diet and Exercise Prevention Pioglitazone [Incretin] [Bromocriptine] Metformin Colsevelam

Synergies In Therapy for the Cardiometabolic Syndrome ?√

Summary  Treat aggressively-benefit on cost and complications  Treat elements of pathophysiology  Resistance-glycemia,endothelial dysfunction,lipids,BP,coag.  Secretion-first phase,incretin,importance of PPG  Multi-hormonal issues  Use SIDE-BENEFITS of the various agents  Treat to new goals using combinations that make pathophysiologic sense  Guidelines should help pick right drug(s) for right patients
