AACE in 2013: a guideline to emphasize
comprehensive management

1. Management of obesity
2. Management of prediabetes
3. Lifestyle intervention, medication and management of insulin
for hyperglycemia

AACE 2013 elevated management for overweight/obesity
and prediabetes to height of prevention and treatment for
macrovascular complications

recommended
Studies of DCCT (1993), Kumamoto (1995) and UKPDS (1998) demonstrated
that controlling glucose strictly can reduce incidence of diabetic microvascular
complications.
Subsequently, in 2008, large-scale ACCORD study, VADT study and
ADVANCE study didn’t demonstrate that intensively reducing level of blood
glucose can reduce incidence of diabetic macrovascular complications.
Reducing level of blood
glucose can reduce
incidence of diabetic
microvascular complications
How to prevent and
treat macrovascular
complications?
Nip it in the bud……
Management for obesity and
prediabetes is associated
with outcome of
macrovascular complications
Lifestyle treatment is essential and
involved through all stages for all
patients with diabetes
1.AACE Consensus Statement.ENDOCRINE PRACTICE Vol 19 (Suppl 2) May/June 2013 1.
AACE 2013 pointed out: Lifestyle is a basis of comprehensive treatment for
diabetes
Lifestyle intervention can be simultaneously
initiated with medications Gradual treatment program is once again verified
to be unreasonable
Lifestyle optimization is essential for all patients with diabetes. Lifestyle
optimization is multifaceted, ongoing, and should engage the entire
diabetes team. However, such efforts should not delay needed
pharmacotherapy, which can be initiated simultaneously and adjusted
based on patient response to lifestyle efforts. The need for medical therapy
should not be interpreted as a failure .

FOR THE TREATMENT OF TYPE 2

Minimizing risk of weight gain is also a
priority. It too is a matter of safety,

modification.
Management of cardiovascular risk factors to reduce the
CV events of T2DM patients. Such kind of management
needs to start early and maintain for the disease whole

α-glycosidase inhibitors can reduce level of

heart and blood vessels Home P. Diabetes Technol Ther. 2012 Jun;14 Suppl 1:S33-42.
1.Home P. Diabetes Technol Ther. 2012 Jun;14 Suppl 1:S33-42.
α-glycosidase inhibitors can play certain protective role for
heart and blood vessels through reducing postprandial
blood glucose. Although there are relatively fewer large
scale of hard endpoint studies for α-glycosidase inhibitors,
their delayed action for CIMT of alternative endpoint can
also evidence the benefit.

Summary
• AACE Guideline for Comprehensive
management for Diabetes 2013: safely lower
glucose, comprehensive management
• AGI listed as alternative first-line medication by
AACE 2013, which can effectively lower BG
without hypoglycemia and weight gain.
Voglibose shows better tolerance.
