3 What is optimal diabetes control? 10 years ago A1c < 7% for most The lower, the better One size fits all ACCORD ADVANCE VADT Standards of Medical Care in Diabetes 2012 The ADA proposes optimal targets, but each target must be individualized to the needs of each patient and his or her disease factors

4 What is optimal diabetes control in 2016? Most people - A1c goal <7% Lower targets (ex: <6.5%) Short duration of DM T2D treated with lifestyle or metformin only Long life expectance No significant CVD Only if this can be achieved without significant hypoglycemia or other adverse effects of treatment Higher targets (ex: <8%) Severe hypoglycemia Limited life expectancy Advanced microvascular or macrovascular complications Extensive comorbid conditions Long-standing DM in whom general goal is difficult to attain

5 How does a health plan achieve optimal A1c control? Piling on?

6 Kaiser Permanente Northern California: Leader in diabetes control #9 in the US for A1c <8% 70% of DM patients have A1c under 8% Regional target = 73% 82% of DM patients have A1c under 9% Regional target = 86%

10 OK, so what medications should I use??

11 Sulfonylureas Glipizide (Glucotrol), Glimiperide (Amaryl) - $ ($100/yr) Stimulates pancreatic beta cell insulin release Advantages Oral Affordable Long clinical exp. microvascular risk (UKPDS) Disadvantages Hypoglycemia risk 1-3% risk for severe hypoglycemia Weight gain (avg <5 kg) 1-2% A1c** **expected decrease in A1c (%) with MONOtherapy, actual A1c lowering when used as 2 nd or 3 rd line agent will be less

20 Case 1- what is the best choice for 3 rd line agent? Tobacco Red is a 48 year-old dye-worker with type 2 diabetes: Smokes 3 packs per day for the last 40 years He has beaten bladder cancer twice in last 10 years His current BMI is 55.3 Last three quarterly A1C levels were: 7.5% 7.8% 8.1% Current meds: Metformin XR 2 gm PO once daily Glipizide 10 mg PO bid Tobacco Red has been stable on this regimen for the last 3 years. At this point, the best course of action would be to...

21 Case 1- what is the best choice for 3 rd line agent? (A) Nothing - 8.1% is not bad, and this guy is likely to die from bladder cancer anyway. (B) Add Pioglitazone (Actos), retest in 3 months (C) Replace glipizide with bedtime NPH and titrate to a fasting glucose level <130. Retest in 3 months. (D) Replace glipizide with a Liraglutide (Victoza), retest in 3 months. (E) C or D Hints: Current meds = Metformin 2000 mg qd, Glipizide 10 bid Considerations: Obesity (BMI 55), smoker

22 Case 1- what is the best choice for 3 rd line agent? Answers: (A) No - technically correct but politically incorrect. (B) No - adding Actos will get you sued when he develops bladder cancer for the 3rd time (C) YES - is correct and cost effective (D) YES - is correct and Liraglutide (Victoza) have a weight negative effect, which this gentleman needs. It s possible this might reduce his risk for CVD death. However, this option is less costeffective. (E) YES either C or D is correct

23 Does Pioglitazone cause bladder cancer? Dormandy, Lancet 2005: 366, PROspective pioglitazone Clinical Trial In macrovascular Events (PROactive) study YES Erdmann, Diabetes Obes Metab 2014: 16, 63 PROactive update NO Lewis, JAMA 2015: 314, 265 Cohort and nested case-control study NO Tuccori, BMJ 2016; 352:i1541 Cohort study YES AHRQ review (Diabetes Medications for Adults With Type 2 Diabetes: An Update, April 2016) - NO Used most rigorous evidence which evaluated people prospectively

24 Leader Trial Liraglutide (Victoza) reduced death from CVD causes Hazard ratio, 0.87; 95% CI, 0.78 to kg more weight loss ~80% had established CVD Unknowns: Helpful for primary prevention? Class effect? (Evaluation of Lixisenatide in Acute Coronary Syndrome (ELIXA) trial no CVD benefit)

25 Case 2 - what is Terry s next best course of action? Terry Treetrunklegs is a 55 year-old lover of salt with type 2 diabetes who recently graduated to the 4th stage of CHF. She is quite proud of her accomplishment and feels a debt of gratitude to her hubby Jim, who makes her six nightly margaritas with salt at her favorite Mexican Restaurant. Her weight has increased by 5 lbs over the last 12 hours. Terry has battled pancreatitis and won four different times. Terry currently takes glipizide 10 mg PO bid Her last three quarterly A1C values: 7.2% 7.8% 8.5%.

26 Case 2 - what is Terry s next best course of action? (A) Add metformin. Gradually titrate to 2,000 mg per day to avoid GI side effects. Retest in 3 months. (B) Add Pioglitazone (Actos) 15 mg. Titrate dose up over the next 6 months based on quarterly A1C values. (C) Increase glipizide to 20 mg PO BID and retest A1C in 3 months. (D) Stop glipizide and start bedtime NPH. Titrate to fasting glucose <130. Recheck an A1C 3 months after achieving a fasting glucose <130. (E) Add Exenatide (Byetta) to glipizide, retest in 3 months. Hints: Current meds = Glipizide 10 bid Considerations: Stage IV CHF, h/o recurrent pancreatitis

27 Case 2 - what is Terry s next best course of action? Answers: (A) NO - Metformin is contraindicated due to risk of lactic acidosis in acute CHF. (B) No Pioglitazone (Actos) contraindicated in CHF class 3 or higher. (C) NO - This will be inadequate to reduce her A1C by the 1.5% needed to achieve goal. (D) YES - Insulin is needed for this patient. Glipizide will be of little value once insulin is added, and it is an extra medication increasing the risk of polypharmacy effects. (E) NO - This is a good way to get sued when Jim and his margaritas provoke pancreatitis bout #5.

28 Case 3 Bernie s next steps? Bernie U. Rheinhard is a 57 year-old with type 2 diabetes whose last three hemoglobin A1C values were, in order, 7.9%, 8.5% and 8.9%. Meds: Metformin 2,000 mg once daily Glipizide 10 mg twice daily She has a prescription for fluconazole 150 mg orally one time for yeast infections with 11 refills, because you are tired of her once monthly complaining of a new yeast infection. Bernie is currently in your office because it "burns hard when she urines." Today is the fourth time she has been in your office with this complaint this year. While analyzing her urine results (nitrite positive), you recognize her A1C trend and decide to adjust her medication.

29 Case 3 Bernie s next steps? You decide to (A) Increase her glipizide to 20 mg orally twice daily (B) Add canagliflozin (Invokana) (C) Add pioglitazone (Actos) (D) Add bedtime NPH insulin (E) B or C

30 Case 3 Bernie s next steps? Answers: (A) NO - technically, she needs a 2.0% reduction in her A1C to achieve goal. No oral hypoglycemic will get her there, and increasing the dosage of one she is already taking most certainly will not get her to goal. (B) NO - this woman is a yeast producing factory who has had four UTIs in the last year. Canagliflozin will only cause more problems and cost a lot, without getting her to goal. (C) NO - This is wrong for the same reason that (A) is wrong. (D) YES - Insulin is the only medication likely to help her achieve the necessary A1C reduction. Cessation of glipizide is probably reasonable at this point. (E) NO - neither (B) or (C) is correct.

31 Case 4 Sugar s second choice? Sugar T. Lowe is a 77 yo lady with longstanding type 2 diabetes (>20 years) who has the local EMS team on her Christmas card list after several visits to the ED for hypoglycemia when she was previously taking glipizide. She also got to see her EMS friends recently after getting out of bed too quickly and conking her head on the nightstand, leading to unconsciousness. Recent A1c 8.4%. Meds: Metformin 1000 bid Donepezil (Aricept) for senior moments (she s very forgetful these days)

32 Case 4 Sugar s second choice? (A) Add Canagloflozin (Invokana). (B) Add Pioglitazone (Actos). (C) Start bedtime NPH. Titrate to fasting glucose less than 130. (D) Add Sitagliptin (Januvia). (E) B or D Hints: Current meds = Metformin 1000 mg bid Considerations: Hypoglycemia, longstanding DM, occasional dizziness, early dementia

33 Case 4 Sugar s second choice? Answers: (A) NO - Canagloflozin (Invokana) would not be a good option in an elderly patient with dizziness/fall risk because it lowers BP. (B) YES - Pioglitazone (Actos) would be a good option in this case, and is costeffective. Target A1c in this lady would be <8% because of history of severe hypoglycemia and comorbid conditions (early dementia), and this target would probably be readily achieved by adding pioglitazone, while you would not increase her risk for hypoglycemia. (C) NO with history of severe hypoglycemia on glipizide, NPH would not be a great option for this lady. (D) YES Sitagliptin (Januvia) would be a good option for the same reasons listed above for Pioglitazone (Actos). However, this option is less cost-effective. (E) YES - either (B) or (D) is correct.
