Question
Do you consider tight glycemic control a
priority in management of type 2 diabetes?”
YES
NO
It depends on the patients

 Is optimizing glycaemic
control important in T2 DM?
Targets
The lower the better?
 Target A1c
 BP control
 Lipid levels
Windows of opportunity?

Is there an evidence base for
tight and timely control of blood
glucose?
UK Prospective Diabetes Study
20-year Interventional Trial from 1977 to 1997
 5,102 patients with newly-diagnosed type 2 diabetes
recruited between 1977 and 1991
 Median follow-up 10.0 years, range 6 to 20 years
 Results presented at the 1998 EASD Barcelona meeting
10-year Post-Trial Monitoring from 1997 to 2007
 Annual follow-up of the survivor cohort
 Clinic-based for first five years
 Questionnaire-based for last five years
Median overall follow-up 17.0 years, range 16 to 30 years

Conclusions
• Despite an early loss of glycemic differences, a
continued reduction in microvascular risk and
emergent risk reductions for myocardial infarction and
death from any cause were observed during 10 years
of post-trial follow-up
• A continued benefit after metformin therapy was
evident among overweight patients.

Major hypoglycaemia was uncommon in ADVANCE and only reported in
231 patients among 11,140 followed for 5 years, 150 in intensive group
and 81 in standard control group
* Represents 0.7 and 0.4 events per 100 patient

HbA1c targets should be individualized
Goal of therapy
 In general: HbA1c <7%
 In the individual patient: HbA1c as close to 6% as possible without significant
hypoglycemia
Call to action: HbA1c 7%
Less stringent goals may be appropriate for:
 Patients with a history of severe hypoglycemia
 Patients with limited life expectancies
 Very young children or older adults
 Individuals with co-morbid conditions
Nathan DM, et al. Diabetes Care 2009;32 193-203.
Other cardiovascular risk factors
 Blood pressure
 Lipid levels
Steno 2: study design
• Study design: randomized, open, parallel trial in Denmark
• Microvascular study: effect of intensive multifactorial strategy on the development of nephropathy
• Macrovascular study: effect of intensive mutifactorial strategy on the incidence of CV events
• Treatments: conventional multifactorial treatment versus intensified multifactorial treatment
• Patients: 160 patients with T2D and microalbuminuria
• Follow-up: 7.8 years

In Conclusion…….
Treatment Strategies for Patients
with Diabetes
Optimum glycemic control
 Dietary and lifestyle changes
 Exercise
 Medication
Prevention of microvascular complications
 Control of glycemia
 Control of blood pressure
 Monitoring and screening
Prevention of CHD, MI, and other macrovascular complications

Implications of Optimal Management
– for the System
Multidisciplinary F/U
Intensive monitoring
Regular health checks
Regular screening
Regular Intervention
Increasing medication costs
Escalating healthcare costs
