CLINICAL CLASSIFICATION OF DIABETES
● Type 2 diabetes (results from a progressive insulin secretory defect on
the
background of insulin resistance)
Pharmaceuticals
● Type 1 diabetes (results from -cell destruction, usually leading to
absolute
insulin deficiency)
● Other specific types of diabetes due to other causes, e.g.,
genetic defects in cell function,
genetic defects in insulin action,
diseases of the exocrine pancreas (such as cystic fibrosis), and
drug or chemical-induced (such as in the treatment of AIDS or
after organ transplantation)
● Gestational diabetes mellitus (GDM) (diabetes diagnosed during
pregnancy)
Diabetes Care, Jan 2008
CRITERIA FOR THE DIAGNOSIS OF DIABETES

CRITERIA FOR TESTING FOR PRE-DIABETES AND DIABETES IN
ASYMPTOMATIC ADULT INDIVIDUALS
1. Testing should be considered in all adults who are overweight (≥ BMI 25
kg/m2*)
and have additional risk factors:
● physical inactivity
● first-degree relative with diabetes
● members of a high-risk ethnic population (e.g., African American,
Latino,
Native American, Asian American, and Pacific Islander)
● women who delivered a baby weighing 9 lb or were diagnosed with
GDM

A1C
Preprandial capillary plasma glucose
R
Peak postprandial capillary plasma glucose†
(10.0 mmol/l)
Key concepts in setting glycemic goals:
● A1C is the primary target for glycemic control
● Goals should be individualized based on:
● duration of diabetes
● pregnancy status
● age
● co-morbid conditions
● hypoglycemia unawareness
● individual patient considerations
● More stringent glycemic goals (i.e., a normal A1C, <6%) may further
reduce
complications at the cost of increased risk of
hypoglycemia
● Postprandial glucose may be targeted if A1C goals are not met
despite reaching preprandial glucose goals
Diabetes Care, Jan 2008
TESTING FOR PRE-DIABETES AND DIABETES
R
Pharmaceuticals
● Testing to detect pre-diabetes and type 2 diabetes in asymptomatic
people
should be considered in adults who are overweight or obese (BMI ≥25
kg/m2)
and who have one more additional risk factors for diabetes. In those
without these risk factors, testing should begin at age 45. (B)
● If tests are normal, repeat testing should be carried out at least at 3-year
intervals.(E)
● To test for pre-diabetes or diabetes, either an FPG test or 2-h oral
glucose tolerance test (OGTT; 75-g glucose load), or both, is appropriate.
(B)
● An OGTT may be considered in patients with impaired fasting glucose
(IFG) to better define the risk of diabetes. (E)
● In those identified with pre-diabetes, identify and, if appropriate, treat

TESTING FOR TYPE 2 DIABETES IN CHILDREN
R
● Family history of type 2 diabetes in first- or second-degree
relative
● Race/ethnicity (Native American, African American, Latino, Asian
American, Pacific Islander)
Pharmaceuticals
Test children who are overweight (BMI >85th percentile for age and sex,
weight for height >85th percentile, or weight >120% of ideal for height) and
have two of the following risk factors:
● Signs of insulin resistance or conditions associated with insulin
resistance (acanthosis nigricans, hypertension,
dyslipidemia, or
polycystic ovary syndrome [PCOS])
● Maternal history of diabetes or gestational diabetes mellitus
(GDM) (E)
● Testing should begin at age 10 years or at onset of puberty, if
Diabetes Care, Jan 2008
puberty
occurs at a younger age, and
be repeated
SELF-MONITORING OF BLOOD GLUCOSE (SMBG)
R
● For patients using less frequent insulin injections, non-insulin therapies,
or
medical nutrition therapy (MNT) alone, SMBG may be useful in
achieving
glycemic goals. (E)
Pharmaceuticals
● SMBG should be carried out three or more times daily for patients using
multiple
insulin injections or insulin pump therapy. (A)
● To achieve postprandial glucose targets, postprandial SMBG may be
appropriate. (E)
● When prescribing SMBG, ensure that patients receive initial instruction
in, and routine follow-up evaluation of, SMBG technique and their ability to
use
data to adjust therapy. (E)

R
A1C
● Perform the A1C test quarterly in patients whose therapy has changed
or
who are not meeting glycemic goals. (E)
Pharmaceuticals
● Perform the A1C test at least two times a year in patients who are
meeting
treatment goals (and who have stable glycemic control).
(E)
● Use of point-of-care testing for A1C allows for timely decisions on
therapy
changes, when needed. (E)
Diabetes Care, Jan 2008
GLYCEMIC GOALS
R
Pharmaceuticals
● Lowering A1C to an average of ~7% has clearly been shown to reduce
microvascular and neuropathic complications of diabetes and,
possibly,
macrovascular disease.
Therefore, the A1C goal for non-pregnant adults in general is <7%.
(A)
● Epidemiologic studies have suggested an incremental (albeit, in absolute
terms, a small) benefit to lowering A1C from 7% into the normal range.
Therefore, the A1C goal for selected individual patients is as close
to
normal (<6%) as possible without significant hypoglycemia. (B)
● Less stringent A1C goals may be appropriate for patients with a history
of severe
hypoglycemia, patients with limited life expectancies, children,
individuals
with co-morbid conditions, and those with longstanding diabetes
and
minimal or stable microvascular complications. (E)
Diabetes Care, Jan 2008
R
MEDICAL NUTRITION THERAPY (MNT)
● Individuals who have pre-diabetes or diabetes should receive
individualized
MNT as needed to achieve treatment goals, preferably provided
by a
registered dietitian familiar with the components of diabetes MNT.
(B)
Pharmaceuticals
GENERAL RECOMMENDATIONS:
● MNT should be covered by insurance and other payors. (E)
Diabetes Care, Jan 2008
MEDICAL NUTRITION THERAPY (MNT)
R
● In overweight and obese insulin resistant individuals, modest weight
loss has
been shown to reduce insulin resistance. Thus, weight
loss is recommended for all overweight or obese individuals who have
or are at risk for diabetes. (A)
Pharmaceuticals
ENERGY BALANCE, OVERWEIGHT, AND OBESITY
● For weight loss, either low-carbohydrate or low-fat calorie-restricted
diets
may be effective in the short term (up to 1 year). (A)
● For patients on low-carbohydrate diets, monitor lipid profiles, renal
function
and protein intake (in those with nephropathy), and adjust
hypoglycemic
therapy as needed. (E)
● Physical activity and behavior modification are important components
Diabetes Care, Jan 2008
of weight
MEDICAL NUTRITION THERAPY (MNT)
R
● Sugar alcohols and nonnutritive sweeteners are safe when consumed
within
the acceptable daily intake levels established by the FDA. (A)
● If adults with diabetes choose to use alcohol, daily intake should be
limited to a
moderate amount (one drink per day or less for adult women and
two
drinks per day or less for adult men). (E)
Pharmaceuticals
OTHER NUTRITION RECOMMENDATIONS
● Routine supplementation with anti-oxidants,such as vitamins E and C
and
carotene, is not advised because of lack of evidence of efficacy
and
concern related to long-term safety. (A)
● Benefit from chromium supplementation in people with diabetes or
obesity

R
PHYSICAL ACTIVITY
● In the absence of contraindications, people with type 2 diabetes
should be
encouraged to perform resistance training three times per
week. (A)
Pharmaceuticals
● People with diabetes should be advised to perform at least 150
min/week of
moderate-intensity aerobic physical activity (50–70% of
maximum
heart rate). (A)
Diabetes Care, Jan 2008
IMMUNIZATION
R
● Provide at least one lifetime pneumococcal vaccine for adults with
diabetes.
A one-time revaccination is recommended for individuals ≥65 years
of
age previously immunized when they were <65 years of age if the
vaccine
was administered >5 years ago. Other indications for repeat
vaccination
include nephrotic syndrome, chronic renal disease, and
other immunocompromised states, such as after transplantation. (C)
Pharmaceuticals
● Annually provide an influenza vaccine to all diabetic patients ≥6 months
of age. (C)
Diabetes Care, Jan 2008
HYPERTENSION / BLOOD PRESSURE CONTROL
R
● Blood pressure should be measured at every routine diabetes visit.
Patients
found to have SBP of ≥130 mmHg or DBP ≥80 of mmHg
should have BP
confirmed on a separate day. Repeat SBP of
≥130mmHg or DBP of ≥80mmHg confirms a diagnosis of HPN. (C)
GOALS

● Patients with a SBP of 130–139 mmHg or a DBP of 80–89mmHg may be
given
lifestyle therapy alone for a maximum of 3 months. If targets are not
achieved, add pharmacological agents. (E)
● Patients with more severe hypertension (SBP ≥140 or ≥DBP 90 mmHg) at
diagnosis
or follow-up should receive pharmacologic therapy in addition to
lifestyle
therapy. (A)
● For patients with DM & HPN start with either an ACEI or an ARB. If one
class is
not tolerated, the other should be substituted. If needed to
achieve BP, a thiazide diuretic should be added to those with an estimated
GFR of ≥ 50
ml/min per 1.73 m2 and a loop diuretic for those with an estimated
GFR of <50 ml/min per 1.73 m2. (E)

HYPERTENSION / BLOOD PRESSURE CONTROL
R
● Multiple drug therapy (2 or more agents at maximal doses) is generally
required to
achieve BP targets. (B)
Pharmaceuticals
TREATMENT
● If ACEI, ARBs, or diuretics are used, kidney function and serum potassium
levels should be closely monitored. (E)
● In pregnant patients with DM & chronic HPN, BP target goals of 110–129 /
65–79 mmHg are suggested in the interest of long term maternal health
and
minimizing impaired fetal growth. ACEI and ARBs are
contraindicated during pregnancy. (E)

DYSLIPIDEMIA / LIPID MANAGEMENT
R
● In most adult patients, measure fasting lipid profile at least annually.
In adults with low-risk lipid values (LDL-C cholesterol <100 mg/dl, HDLC > 50 mg/dl, and triglycerides < 150 mg/dl), lipid assessments may be
repeated
every 2 years. (E)

Pharmaceuticals
TREATMENT RECOMMENDATIONS AND GOALS
● Lifestyle modification focusing on the reduction of saturated fat, trans fat,
and cholesterol intake; weight loss (if indicated); and increased
physical activity should be recommended to improve the lipid profile
in
patients with diabetes. (A)
● Statins should be added to lifestyle therapy, regardless of baseline lipid
levels,
for diabetic patients:
● with overt cardiovascular disease (CVD) (A)
● without CVD who are over the age of 40 and have one or more
other
CVD risk factors. (A)
● For patients at lower risk than those mentioned above (e.g., without overt
CVD and
under the age of 40), statins should be considered in
addition to lifestyle
therapy if LDL-C remains >100 mg/dl or in those with multiple CVD
risk
factors. (E)

DYSLIPIDEMIA / LIPID MANAGEMENT
Pharmaceuticals
TREATMENT RECOMMENDATIONS AND GOALS
R
● In individuals without overt CVD, the primary goal is an LDL-C <100 mg/dl
(2.6 mmol/l). (A)
● In individuals with overt CVD, a lower LDL-C goal of <70 mg/dl (1.8 mmol/l),
using
a high dose of a statin, is an option. (E)
● If drug-treated patients do not reach the above targets on maximal tolerated
statin
therapy, a reduction in LDL-C of ~40% from baseline is an alternative
therapeutic goal. (A)
● Triglycerides levels <150 mg/dl (1.7 mmol/l) and HDL-C levels >40 mg/dl
(1.0
mmol/l) in men and >50 mg/dl (1.3 mmol/l) in women are desirable.
However, LDL-C -targeted statin therapy remains the preferred
strategy.

ANTI-PLATELET AGENTS
R
Pharmaceuticals
● Use aspirin therapy (75–162 mg/day) as a secondary prevention strategy in
diabetic individuals with a history of CVD. (A)
● Use aspirin therapy (75–162 mg/day) as a primary prevention strategy in
those with
type 1 or type 2 diabetes at increased CV risk, including
those who are 40
years of age or who have additional risk factors
(family history of CVD,
HPN, smoking, dyslipidemia, or albuminuria).
(A)
● Aspirin therapy is not recommended in people under 30 years of age, due
to lack of
evidence of benefit, and is contraindicated in patients under
the age of
21 years because of the associated risk of Reye’s
syndrome. (E)
● Combination therapy using other antiplatelet agents such as clopidrogel in
addition
to aspirin should be used in patients with severe and
progressive CVD. (C)
Diabetes
Care, Jan 2008
● Other antiplatelet agents may be a reasonable alternative for

● In asymptomatic patients, evaluate risk factors to stratify patients by 10year risk,
and treat risk factors accordingly. (B)
TREATMENT
Pharmaceuticals
SCREENING
● In patients with known CVD, ACEI, aspirin, and statin therapy (if not
contraindicated) should be used to reduce the risk of CV events.
(A)
● In patients with a prior MI, add -blockers (if not contraindicated) to reduce
mortality. (A)
● In patients >40 years of age with another CV risk factor (HPN, family
history, dyslipidemia, microalbuminuria, cardiac autonomic neuropathy, or
smoking), ACEI, aspirin, and statin therapy (if not contraindicated)

● To reduce the risk or slow the progression of nephropathy, optimize glucose
control. (A)
● To reduce the risk or slow the progression of nephropathy, optimize BP
control. (A)
SCREENING:
● Perform an annual test to assess urine albumin excretion in type 1 diabetic
patients
with diabetes duration of ≥ 5 years and in all type 2 diabetic patients,
starting at diagnosis. (E)
● Measure serum creatinine at least annually in all adults with diabetes
regardless
of the degree of urine albumin excretion. The serum
creatinine should
be used to estimate GFR and stage the level
of chronic kidney disease
(CKD), if present. (E)

albuminuria,
ACEI have been shown to delay the progression of
nephropathy. (A)
ARBs
● In patients with type 2 DM, HPN & microalbuminuria, both ACEI &
