Practical Implementation as a Discussion with the Patient Practical Use of SGLT-2 Inhibitors in T2DM: Clinical Pearls- Perlas de Sabiduria Stan Schwartz MD, FACP Affiliate, Main Line Health System Emeritus, Clinical Associate Professor of Medicine, U of Pa.

Impact of Intensive Therapy in Type 2 Diabetes Summary of Major Clinical Trials: BUT Subset Evaluations Show Reduced CV Outcomes if shorter duration of DM, without significant pre-existing complications StudyMicrovascularMacrovascularMortality UGDP ↔↔↔ UKPDS ↓↓↔↓↔↓ DCCT/EDIC* ↓↓↔↓↔ ↔ ACCORD ↓↔ ↑ (unadj.), ↔ (adj.) ADVANCE ↓↔↔ VADT ↔↔↔ Initial Trial Long Term Follow-up ↑- likely due to hypoglycemia and weight gain

Early Treatment Decreases Micro and Macro Vascular RISK/ OUTCOMES As long as do without Undue Hypoglycemia or Weight Gain Pearl

Consequences of Hypoglycemia Prolonged QT- intervals - Diabetologia 52:42,2009 –Can be of pronged duration IJCP Sup 129, 7/02 –Greater with higher catecholamine levels Europace 10,860 Associated with Angina Diabetes Care 26, 1485, 2003 / Ischemic EKG changes Porcellati, ADA2010 Associated with Arrhythmias Associated with Sudden Death Endocrine Practice 16,¾ 2010 Increased Variabilty - explains highest mortality in intensive group had highest HgA1c in ACCORD ( i ncreases inflammation, ICU mortality Hirsch ADA2010) Sulfonylureas block Ischemic Preconditioning

There is No perfect Exogenous Insulin: All result in HyperInsulinemia and Potential Hypoglycemia Exogenous Insulin Perfect glucose sensor- Insulin secretion modulator Hypoglycemia/ Wt. Gain NORMAL: Insulin into portal system and B-cell= CONCLUSION: DELAY INSULIN THERAPY; AVOID BOLUS RX if possible

Pearl No more Sulfonylureas or Glinides Delay Insulin Most will not need Bolus Insulin
