Objectives
• Recognize incidence, risk factors, and consequences of post-transplant diabetes mellitus (PTDM) among liver recipients
• Identify short-term and long-term complications related to PTDM
• Understand role of registered dietitian (RD) in management of PTDM
• Describe use of Stages of Change in the management of PTDM
Liver Transplant
• 5 year survival after Orthotopic Liver Transplant (OLT)
• 70-80%• Good Quality of Life
• New Challenge … long-term management• Cardiovascular disease: among most serious
conditions to develop after transplant• Diabetes: leading risk factor for CVD
Benten 2009
Immunosuppressant Side Effects
• Major cause long-term mortality & morbidity after OLT
• >1/2 deaths after 3 year survival:• Atherosclerotic cardiovascular disease
(ASCVD)• Correct or control potentially reversible CV risk
factors (i.e. DM, dyslipidemia, obesity, hypertension)
• De novo malignancies• Regular surveillance
Benten 2009, Reuben 2001
Drug Effects
Benten
Adverse effect Ciclo-sporin
Tacro-limus
Gluco-corticoids
Azathioprine Myco-phenolate mofetil
mTOR inhibitors
Arterial HTN +++ ++ +++ - - +
Hyperglycemia, DM
- (?) + +++ - - -
Hyperlipidemia ++ + ++ - - +++
Nephrotoxicity +++ (K+, Mg2+)
+++ (K+, Mg2+)
- - - + (proteinuria)
DM Etiology
• Tissue resistance to insulin-mediated glucose uptake
• β-cell failure, inability to compensate for insulin resistance
Rizvi
Immunosuppressants & DM Etiology
• Corticosteroids• Increase insulin resistance• Increase hepatic gluconeogenesis• Decrease glucose use in muscle and adipose
tissue
• Calcineurin Inhibitors (CNIs)• Increase insulin resistance• Pancreatic beta-cell toxicity
Rizvi 2004, Marchetti 2005
Hyperglycemia Outcomes
• Short-term consequences• Infections• Graft rejection
• Long-term consequences• Microvascular complications• Progressive HCV disease• Increased risk ASCVD
Rizvi 2004, Swift 2006
DM & Other Side Effects
• DM risk increases with obesity & sedentary lifestyle
• Microvascular complications responsible for most adverse outcomes
• Link between DM2 & CVD major determinant early mortality
• Risk for future CV event: Presence of DM2 = Established CVD
• DM v. no DM: 2 to 4 fold increased risk for MI
Rizvi, Horan
DM & Other Side Effects
• Expanding perception of DM
• Cluster of risks:
• Each impacts at least one other
• Each contributes to overall risk ASCVD
• Immunosuppressants increase risk of each
Rizvi 2004, Horan 2006, Beckman
Immunosuppressant Side Effects
Arterial HTN
Hyperglycemia / DM
Nephrotoxicity
Dyslipidemia
Risk ASCVD
Diet
Obesity/Overweight
PTDM: Diagnosis & Incidence
• American Diabetes Association & World Health Organization diagnostic criteria:
• Fasting plasma glucose ≥126 mg/dL (7 mM)
• OLT recipients pre-transplant• 10-30%
• New-onset diabetes mellitus (NODM) in OLT recipients
• 20-40%• Incidence is cumulative over time
Marchetti 2005, Benten 2009, Ma 2005, Oufroukhi 2008, Steinmüller 2000, Reuben 2001
PTDM: Risk Factors
• HCV
• Immunosuppressant type/dose: CNI, Steroids
• Pre-transplant glycemia
• Alcohol
• Recurrent viral disease
• Family history
• African-American or Hispanic ethnicity
• Male gender
• Age >40 years
• Increased weight
• Metabolic syndrome
Marchetti 2005, Benten 2009, Ma 2005, Oufroukhi 2008, Steinmüller 2000, Reuben 2001
Diabetes Impact
What can we do?
DM: Change Outcomes
• Improved Glycemic control decreased microvascular risk, DM dyslipidemia
• Hemoglobin A1c• DCCT: 1% decrease 60% decrease
microvascular complication• UKPDS (over 10 year follow-up): every 1%
decreases 37% decrease microvascular complications
• 5% weight loss • Increased insulin sensitivity• Decreased fasting blood glucose• Decreased medication needs
Horan 2006, Beckman
DM: Interventions
• Lifestyle modification
• Diabetes Self-management Education (DSME)
• General guidelines:• More Intensive• Clear guiding theory• Face-to-face delivery• Inclusion physical activity• Include cognitive restructuring and
patient/educator interaction• Team management
Rizvi 2004, Skinner 2008
DM: Interventions
• Individual counseling with RD• 1.9% reduction in HbA1c with intensive RD
intervention• Better outcomes than with medication alone
• Patient-tailored• Simplified educations among lower literacy
patients Improved comprehension and compliance
Rizvi 2004, Swift 2006, Bantle 2008 2004, Horan 2006, Wilson
DM: Interventions
• Structured group education • Greater weight loss• Less likely to smoke• Greater changes in illness beliefs• Lower depression
• More facilitative, less didactic education • Greater change in illness beliefs
• Patient empowerment – patients involved in setting realistic goals according to their lifestyles
Davies 2008, Skinner 2008, Horan 2006
DM: Nutrition Care
• No more taboo foods
• Research refutes a specific “diabetic diet”
• Meal planning based on individual preferences better compliance and achievement metabolic goals
Rizvi 2004, Swift 2006, Bantle 2008, Horan 2006
DM: Nutrition Care
• Carbohydrate consistency• 45-65% total calories• Provide energy, fiber, vitamins, minerals• Meals may vary from each other, but daily
amounts at each should be constant• Snacks not required• Unnecessary to eliminate sucrose• No research to support one method versus
another for carbohydrate content estimation
Bantle 2008, Swift 2006
DM: Transtheoretical Model / Stages of Change
• Precontemplation: No intent to change behavior within next 6 months
• Contemplation: Stated intent to change behavior within next 6 months
• Preparation: Intention to take specific steps toward behavior change within the next month
• Action: Overt behavior changes within the past 6 months - not yet well-established
• Maintenance: Behavior changes have lasted greater than 6 months
Vallis 2004
Traditional interventions are action-oriented
Those in pre-action stages do not benefit
DM: Transtheoretical Model / Stages of Change
• Individuals with DM in action phases compared to pre-action stages
• Fewer calories from fat• Lower BMI• More likely DSME in past year• More frequent MD appointments• Less likely to smoke• Fewer psychosocial problems• Older, more females, more insulin users
Vallis 2004
DM: Transtheoretical Model / Stages of Change
• Chicken or egg?
• Controllable:• DSME & medical follow-up frequency• Social interventions to improve QoL &
support
• Non-controllable:• Take factors into account when intervening
Vallis 2004
PTDM: Management
• Immediate post-transplant• In-patient education:
• Motivate to participate in glycemic control• Rationale to limit carbohydrate foods to 3 meals• Carbohydrate foods• Non-carbohydrate snack examples
• Refer as needed for outpatient follow-up after discharge
PTDM: Management
• Commonly Used Insulin Preparations post-OLT
Preparation Action Onset (h)
Peak Action (h)
Effective Action duration (h)
Maximum duration (h)
Insulin aspart
(NovoLog)
¼ - ½ ½ - 1 ¼ 3-4 4-6
Basal Insulin
3-4 8-16 18-20 20-24
PTDM: Management
• Chronic post-transplant• All patients attend 4 month follow-up• RD education• Screen for additional education needs
Chronic Post-transplant
• Content: Mediterranean diet/lifestyle
• Goal: • Reduce risk factors for ASCVD
• Manage long-term immunosuppressant side effects
• Format: interactive
• Stages of change: • Provide motivation for behavior change• Encourage incremental steps
• Patient-centered: • Provide patients with lipid profiles• Instruct to set personal goals
Chronic Post-transplant
• Diabetes Assessment Risk Tool• Diagnosis status, BMI, dyslipidemia,
hypertension, medication/insulin
• Referral as needed to Diabetes Education Program
