1 Susan Alexander, DNP, CNS, CRNP, BC- ADM College of Nursing University of Alabama in Huntsville Clinical Affiliation: Outpatient Diabetes Self-Management Education Crestwood Medical Center Huntsville, AL

2  Describe factors associated with worsening of DM control in the patient with pre-TXP DM.  Describe risk factors associated with development of DM in the post-TXP patient  Discuss management strategies for optimization of DM control in the post-TXP patient.

3  Diabetes Mellitus: Heterogeneous Condition With Hyperglycemia and Common Complications  Insulin Deficiency: Relative or Absolute

4 Diabetes occurs post transplant at rate of: 9% at 3 months 16% at 12 months 24% at 36 months Risk factors: Age >40-45, Obesity, AA and Hispanic Race, Family History, Hepatitis C and CMV, Polycystic kidneys Post-transplant Diabetes Mellitus in Renal Transplant Recipiants. Tobin, G et al, UpToDate, May 31, 2008.

5  Calcineurin Inhibitors  Reversible islet cell toxicity, (tacrolimus)  Glucocorticoids are insulin antagonists that  insulin resistance, hepatic glucose production and inhibit glucose transport into cells  Screening for Diabetes: -Monitor blood sugar prior to transplant -Monitor blood sugar post transplant with FBS weekly X4, recheck in 3 months, 6 months and annually thereafter Post-transplant Diabetes Mellitus in Renal Transplant Recipients. Tobin, G et al, UpToDate, May 31, 2008.

6 Fat Adapted from Kruszynska YT, et al. J Invest Med. 1996;44: Henry RR. Ann Intern Med. 1996;124: Liver Pancreas Peripheral Tissues (Skeletal Muscle and Adipose Tissue) Glucose Insulin Resistance Increased Glucose Production Impaired Insulin Secretion Hyperglycemia in Type 2 Diabetes

7  Type 1: -Steroids increase insulin requirement and dose -Insulin dose will increase from ESRD to having a working kidney  Type 2 -Cannot use all oral agents -Usually require insulin -Insulin and/or oral agent dose will increase from ESRD to having a working kidney

8  Large blood vessel disease  MI, stroke, peripheral artery disease and LE amputation  Small vessel disease  retinopathy/vision loss and blindness, kidney damage/renal failure  Neuropathy with pain, loss of protective sensation

9  Hyperglycemia  Severe hyperglycemia (BG>250)  Does improving glycemic control relate to improved outcomes for patients?  Medical ICU, CV surgery and general surgery patients have higher risk of death if hyperglycemia is present.

10  Medications  Food intake  Tests and procedures  Prior history  Nutritional status Inzucchi, S. N Engl J Med 2006;355:

11  IV insulin infusion  Hourly BG monitoring  Transition to subcutaneous  Overlap IV and subcutaneous Insulin  Type 2 DM with <2u/h Inzucchi, S. N Engl J Med 2006;355:

12 Before meals: - Regular insulin (R) - Rapid-actingAnalog Correction Dose: insulin sensitive/resistant Adjust dose based on BG before lunch, supper or HS Inzucchi, S. N Engl J Med 2006;355:

13  ADA: ICU target = As close to 110 as possible and <180. General med. target = and <180 after meals.  ACE: ICU target = <110. General med. Target = <110 with max of 180.  Guidelines are controversial, not based on clinical data from non-ICU patients. Inzucchi, S. N Engl J Med 2006;355:

14  No Food Intake: Give IV infusion or basal insulin qd or bid + regular or rapid acting analog q 6h based on blood glucose.  Continuous Enteral Feeding: Basal insulin + correction dose q 6h. If feeding interrupted, give IV glucose to prevent hypoglycemia.  Total Parenteral Nutrition: Add regular insulin to IV bag and titrate dose in increments of 5-10u/liter.  Reassess insulin requirement with any change in nutritional status. Inzucchi, S. N Engl J Med 2006;355:

15  Medical and surgical ICU targets: Suggest <140 and consider <110  IV insulin allows more rapid titration and absorption in critically ill  Non critically ill target: pre meals  Adjust dose q 1-2 days to optimize glycemic control ASAP Inzucchi, S. N Engl J Med 2006;355:

16  Before making insulin adjustment, consider factors that can cause hyperglycemia: -Missed insulin doses -Snacking -Infection -BG testing and/or insulin administration after versus before meals  Frequent monitoring and dose adjustment is essential. Adjust dose based on fingerstick BG before each meal and HS.  Transition to out patient regimen requires education of patient and a manageable regimen.

17  Insulin NPH QD or BID u/kg/day or 50% of IV insulin dose  Insulin Detemir QD or BID u/kg/day or 50% of IV insulin dose  Insulin Glargine Q day 0.2u/kg/day or 50% of IV insulin dose

18  Regular, Lispro, Aspart, Glulisine  0.20 units/kg/meal or 50% of IV insulin dose type 2 Diabetes  0.30 units/kg/meal or 50% of IV insulin dose High Steroid Dose  Consistent carb intake across meals (45-60 grams/meal) to avoid hypo- and hyperglycemia  Adjust each dose by % q 1-2 days until pre- meal BG is in target

19 NormalGoal HbA1c4-6%<7% * Pre-prandial Blood Sugar mg/dl mg/dl (70-120) Post-prandial Blood sugar <140 mg/dl<180 mg/dl (<160) Diabetes Care 29:S4-S42, 2006 * As close to 6.0% as possible ADA Recommendation: Check A1c at least 2 x/yr if in target and stable; q 3 months if therapy has changed or not meeting goals. Diabetes Care 29:S4- S42, 2006

20  Provides vital data for clinical decision making  Provides patient with accountability and feedback about his/her behavior  Advise patient about: -Appropriate meter -When to test -How to record results -How to interpret and respond to results -Insurance/financial issues, prescription required for reimbursement

21

22  Set small, reasonable goals: Something is better than nothing  Long term goal: Aerobic activity 30 minutes per day, 5 days per week, 1-3 sessions per day; resistance/strength training 3x/week

23  Chair exercises  Strength training  Water exercise

24  2896 adults with DM interviewed from  Outcomes: All cause and CVD mortality over 8- years RESULTS:  Walking 17-minutes/day 39% in all cause mortality; 34% in CVD  Walking 30 minutes/day 46% all cause mortality; 47% in CVD Arch Intern Med Jun 23;163(12):

28  Treatment of type 2 diabetes in patients on metformin or sulfonylurea and not taking insulin  Byetta 5 mcg bid x 1 month, the 10 mcg bid within 1 hour of meal  Liraglutide 0.6 mg per day for one week, then 1.2 mg daily with max. dose ofto 1.8 mg (2).

29  Stimulates first phase insulin release by pancreas when glucose levels are elevated  Reduces glucagon secretion  Slows Gastric Emptying (gastric emptying is accelerated in diabetes)  Reduces caloric intake by promoting satiety

30  Symlin =synthetic Amylin. Amylin is co-secreted with insulin by pancreatic beta cells in response to food intake.  Reduces Postprandial Glucagon  Postprandial Glucagon is Excessive and Not Corrected by Exogenous Insulin in Diabetes  Slows Gastric Emptying Gastric Emptying Is Accelerated in Diabetes  Reduces Caloric Intake by promoting satiety *** Slowed gastric emptying will effect immunosuppressive drug levels ***

31  Described by duration of action - Absorption -Clearance Maintenance Insulin (Basal) -Dose effectiveness evident in fasting blood glucose -Dose is based on body mass and insulin sensitivity Meal Insulin -Impacts post prandial blood glucose -Dose based on meal timing and size, insulin sensitivity

39  Fluctuating prednisone dose requires frequent monitoring of blood sugar and flexibility in insulin and/or oral medication dosing  Prednisone will increase appetite  Insulin or oral medication doses will increase after kidney transplant

40  Adjust dose and number of injections based on home capillary glucose readings  Monitor in 1-2 week intervals  Steroid-induced hyperglycemia is less severe when dose is < 10mg/day  Prednisone dosed in morning  elevated lunch and suppertime glucose, minimally elevated FBG

41 Continuous, automatic monitoring of glucose in the subcutaneous tissue
