Susan Alexander, DNP, CNS, CRNP, BCADM College of Nursing University of Alabama in Huntsville Clinical Affiliation: Outpatient Diabetes Self-Management Education Crestwood Medical Center Huntsville, AL 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. Diabetes Mellitus: Heterogeneous Condition With Hyperglycemia and Common Complications Insulin Deficiency: Relative or Absolute 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. 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. Hyperglycemia in Type 2 Diabetes Peripheral Tissues (Skeletal Muscle and Adipose Tissue) Pancreas Impaired Insulin Secretion Glucose Liver Increased Glucose Production Insulin Resistance Fat Adapted from Kruszynska YT, et al. J Invest Med. 1996;44:413-428. Henry RR. Ann Intern Med. 1996;124:97-103. 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 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 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. Medications Food intake Tests and procedures Prior history Nutritional status Inzucchi, S.

N Engl J Med 2006;355:1903-11 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;355:1903-11 ADA: ICU target = As close to 110 as possible and <180. General med. target = 90-130 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;355:1903-11 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;355:1903-11 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: 90-150 pre meals Adjust dose q 1-2 days to optimize glycemic control ASAP Inzucchi, S. N Engl J Med 2006;355:1903-11 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.
