Objectives:
• Based on the American Diabetes Association Standards of Medical
Care in Diabetes – 2013:
• Identify the classification, risk factors, diagnosis, and screening
criteria for diabetes
• Explain pharmacologic and non-pharmacologic treatments options
for patients with diabetes or pre-diabetes
• Describe measures that can be taken to prevent diabetes
progression and complications including immunization
recommendations
2
Objectives:
•
Identify the class, mechanism of action, dosing, and administration of new
and common diabetes medications
•
Discuss with patients and other health care practitioners diabetes treatment
options, monitoring, and the goals for therapy
•
Compare and contrast medication therapies available for the treatment of
diabetes and select appropriate options for a given patient
•
Develop a comprehensive care plan for a given patient with diabetes which
included pharmacologic and non-pharmacologic measures, monitoring, and
preventative measures
3
“What is Diabetes?” Warm-up
• Spend 60 seconds thinking about and writing down a
description of Diabetes
• Spend the next 2 minutes sharing your description with
someone next to you
• Write down some of the concepts you come up with
4
“What is Diabetes?” Warm-up
• Endocrine condition that increases risks of Cardiovascular
events v.
• Cardiovascular disease with abnormal processing and
distribution of glucose
• Others?
5
Review: Diabetes Pathogenesis
• Insulin deficiency
• Quantitative: decreased in production by the β-cells of the pancreas
• Qualitative: insulin resistance especially muscle, liver, adipose,
myocardial
• Improvements in insulin function
• Weight loss to decrease insulin resistance
• Can in turn improve β-cell function
6
Review: Diabetes Pathogenesis
•
Excess secretion of glucagon by α-cells of pancreas
•
Glucose overproduction by liver; underutilized by body
•
Gluconeogenesis (making glucose from glycerol and amino acids)
•
Renal tubular transport of glucose to the urine due to hyperglycemia
•
Incretin system deviations (relationship to DM still not fully clear)
•
Glucagon-like peptide 1 (GLP-1)
•
Glucose dependent insulinotropic peptide (GIP)
7
Who has Diabetes?
• Incidence of diabetes is rising (about 25 million adults in the US)
• Incidence is higher in certain populations
• Many risk factors/associated conditions are also rising in prevalence
• About 2/3 of patients with diabetes in the US also have hypertension
(HTN)
• How does Maine compare to the US when it comes to incidence of
Diabetes?

Progress….
• LL follows recommendations from you and his other health care
providers
• He is able to quit smoking with nicotine patches and counseling,
but during this time his weight goes up 2.5 kg
• About 6 months later he begins a diet and exercise program for
patients with Pre-Diabetes
• He is able to loose ~ 20 lbs but has been struggling to keep
from gaining it back
47
Progress….
• LL has tolerated Metformin therapy and is now taking 1
gram BID
• He is exercising more, but he is still having difficulties
balancing his diet
• He was diagnosed with high blood pressure
• Not currently on therapy - improved with smoking
cessation and weight loss
48
8 years later….
• He comes into the pharmacy today for his Metformin refill and
reports bad news…
• Despite his lifestyle changes he has been diagnosed with
type 2 diabetes
• His A1c has reached 8.1% and he has had two FPGs > 140
mg/dL drawn by the lab over 2 weeks
• He is motivated to continue with his lifestyle changes, but
wants to know more about additional medications
49
Adding on more medications
• Individually take 1 minute to list additional diabetes therapies
that could be added to LL’s Metformin for better glycemic
control
• In pairs take a few minutes to discuss your options
• Select and write down one agent/class that you would
recommend for him based on his current status
• Write down why you think it is a good choice for him
50
Adding on Therapy
•
While metformin is still the preferred first line therapy for patients with diabetes, if maximum
doses of metformin do result in an A1C at goal, how should an additional agent be chosen?
•A. The second agent added on should be a Glucagon-Like-Peptide-1 (GLP-1) receptor agonist
•B. The second agent added on should be selected based on patient specific factors with
consideration of cost, potential side-effects, and comorbidities
•C. The second agent should be insulin therapy with insulin glargine daily and insulin aspart or
lispro TID with meals
•D. A second agent should not be added until diet and lifestyle goals have been achieved to
reduce insulin resistance
51
A Patient Centered Approach
• American Diabetes Association (ADA) and the European
Association for the Study of Diabetes (EASD) 2012
recommendations
• Patient be involvement in decision making
• Patient factors be considered in selecting treatments and goals
of therapy
• Most add-on therapy will offer similar glycemic benefit, but
compliance and risk of adverse events varies
Inzucchi SE, Bergenstal RM, Buse JB, et al. Management of hyperglycemia in type 2 diabetes:
a patient52
centered approach, Position Statement by the ADA and the EASD. Diabetes Care. 2012;35:1364-79.
Factors to Consider
•
Think of each element as a continuous spectrum:
•
Patient attitude and expected treatment efforts
•
Risks of hypoglycemia and other adverse events
•
Disease duration
•
Life expectancy
•
Important comorbidities
•
Established vascular complications
•
Resources, support system available

a patient54
centered approach, Position Statement by the ADA and the EASD. Diabetes Care. 2012;35:1364-79.
Factors to Consider
•
•
Factors should also be considered in prescribing lifestyle modifications
•
Setting goals that are realistic
•
Adapting to patient situations
These may include:
•
Access to healthful foods
•
Access to a safe environment for exercise
•
Patient’s physical ability (i.e. Fall risk, respiratory conditions)
55
Adding on Therapy
•
While metformin is still the preferred first line therapy for patients with diabetes, if
maximum doses of metformin do result in an A1C at goal, how should an additional
agent be chosen?
•B. The second agent should be insulin therapy with insulin glargine daily and insulin
aspart or lispro TID with meals
•
This strategy of starting insulin as first line (with or without metformin) may be
appropriate for patients with severe hyperglycemia at time of diagnosis or therapy
initiation
•A1C ≥ 10% or Blood glucose > 300 mg/dL
Inzucchi SE, Bergenstal RM, Buse JB, et al. Management of hyperglycemia in type 2 diabetes:
a patient56
centered approach, Position Statement by the ADA and the EASD. Diabetes Care. 2012;35:1364-79.
Adding on Therapy
• While metformin is still the preferred first line therapy for patients with
diabetes, if maximum doses of metformin do result in an A1C at goal,
how should an additional agent be chosen?
•A. The second agent added on should be a Glucagon-Like-Peptide-1
(GLP-1) receptor agonist
• This may be appropriate for patients in whom weight gain is desirable,
patient has insurance that will cover cost (reasonable copay), and
patient feels comfortable with injectable therapy

Goals for therapy
•
Choosing an A1C goal for a patient should be individualized just like the
therapy selected
•
Guidelines recommend lowering A1C to below or around 7% to reduce
microvascular complications (range 6.5% - 8%)
•
May also reduce macrovascular complications in some patients if
implemented soon after diagnosis
•
For other patients, older, greater duration of disease, benefit of lower A1C
may not outweigh risk of hypoglycemia
•
Variance in cardiovascular outcomes between large trials

Meta-analysis on tight glycemic control
•
•
Lancet 2009: based on 5 randomised trials
•
Intensive therapy reduces coronary events without an increased risk of death
•
Notes variance between populations and rate of A1C reduction
BMJ 2011: based on 14 randomised trials (used trial sequence analysis)
•
Intensive control has not been proven to reduce all cause mortality
•
Increase in relative risk of hypoglycemia by 30 %
•
Evidence insufficient to draw conclusions on cardiovascular mortality, non-
fatal MI, composite microvascular complications, or retinopathy

What should be goal for LL?
• What do you think we should set at LL’s A1C goal?
• How about other goals/plans?
• Self-monitoring of blood glucose (SMBG)
• Preventative Care
• Cardiovascular risk reduction
• Medical Nutrition Therapy (MNT)
72
Potential Plans for LL
• A1C ≤ 7% (depending on response to therapy)
• Check A1C at least twice per year
• Check more often when changing therapies or above goal
• Diabetes Self-Management Education (DSME) and support
• Initial education plus follow-up
• Education should address quality of life and psychosocial issues
• May be recommended for patients with Pre-Diabetes as well

Potential Plans for LL
•
SMBG
•
Part of comprehensive DM education and care discussion with patient
•
Daily monitoring is not required for most patients not taking insulin
•
Consider patient comfort, access to testing supplies, and risk of
hypoglycemia based on medication therapy
•
Goals and frequency should be individualized; can consider:
•
Fasting BG range 70 - 130 mg/dL
•
Peak Post-prandial BG < 180 mg/dL (taken 1-2 hours after meal)
74
American Diabetes Association (ADA) Professional Practice Committee. Standards of medical care in diabetes - 2013. Diabetes Care. 2013;36(1): S11-S66.
Medical Nutrition Therapy
•
Weight loss (overweight/obese) and weight maintenance
•
Use of low carbohydrate, low fat calorie-restricted, or Mediterranean diet
•
Monitor lipids, renal function, and protein intake
•
Individual diet plan for intake of carbohydrates, proteins, and fats
•
Saturated fat < 7 % of total calories (9 calories per gram of fat); limit trans fats
•
Addition of physical activity (design to meet patient’s ability)
•
Increase intake of whole grains to get recommended daily intake for fiber
•
Limit alcohol intake to moderate (1 drink per day women; 2 per day men)
•
Specific vitamin supplementation not currently supported by evidence
75

Cardiovascular Prevention
•
Hypertension
•
New goal option of systolic < 140 mmHg; Diastolic < 80 mmHg
•
Lower targets (< 130 mmHg) may be appropriate for specific patients
(younger)
•
Preferred treatment
•
DASH Diet and lifestyle modification
•
Angiotensin Converting Enzyme (ACE) Inhibitors or Angiotensin Receptor
Blocker (ARB) (monitor renal function and electrolytes)
•
Addition of diurectics or other agents may be required to reach goal
76
American Diabetes Association (ADA) Professional Practice Committee. Standards of medical care in diabetes - 2013. Diabetes Care. 2013;36(1): S11-S66.
Cardiovascular Prevention
•
Hyperlipidemia
•
Monitor fasting lipids annually
•
Or every 2 years if at goal and stable
•
Lifestyle modifications recommended for all patients
•
Recommend addition of HMG-CoA Reductase Inhibitor (statin) therapy
regardless of baseline lipid values if patient has CVD or
•
Over the age of 40 with 1 or more CVD risk factors
•
Family history of CVD, HTN, smoking, albuminuria, dyslipidemia
77
Cardiovascular Prevention
•
Hyperlipidemia
•
•
For lower risk individuals add statin if
•
Lifestyle changes alone do not reduce LDL to < 100 mg/dL
•
Patient has multiple CVD risk factors
If patients do not meet goals (see next slide) on maximum tolerated statin
dosing
•
•
Alternative goal: LDL reduction by 30 - 40 % from baseline
Combination therapy has not been shown to have additional
cardiovascular benefit
