18Correlation of A1C with Estimated Average Glucose
(eAG)
Mean plasma glucose Mean plasma glucose
A1C () mg/dl mmol/l
6 126 7.0
7 154 8.6
8 183 10.2
9 212 11.8
10 240 13.4
11 269 14.9
12 298 16.5
These estimates are based on ADAG data of 2,700
glucose measurements over 3 months per A1C
measurement in 507 adults with type 1, type 2,
and no diabetes. The correlation between A1C and
average glucose was 0.92. A calculator for
converting A1C results into estimated average
glucose (eAG), in either mg/dl or mmol/l, is
available at http//professional.diabetes.org/Gluc

40Early and aggressive insulin therapy
- Reduces long-term vascular risk and potentially
may prolong B-cell lifespan and - Function.
- .
41- initiating combination therapy or insulin
immediately for all patients with A1C 9 at
diagnosis.
42- Recent clinical treatment guidelines, suggest
that these agents may be less effective as add-on
therapy for patients with an A1C 9.5 and
therefore recommend the initiation of insulin in
all patients with an A1C gt 10.
43Indication for insulin therapy
44ketosis-prone type 2 diabetes
- At presentation, they have markedly impaired
insulin secretion and insulin action, but
aggressive management with insulin improves
insulin secretion and action to levels similar to
those of patients with type 2 diabetes without
DKA.
45- Recently, it has been reported that the
nearnormoglycemic remission is associated with a
greater recovery of basal and stimulated insulin
secretion and that 10 years after diabetes onset,
40 of patients are still non-insulin dependent.
46- Fasting C-peptide levels of gt1.0 ng/dl (0.33
nmol/1) and stimulated C-peptide levels gt1.5
ng/dl (0.5 nmol/1) are predictive of long-term
normoglycemic remission in patients with a
history of DKA.

intensification

- Initiation
- Optimisation
- Intensification
48Patient barriers
49Physician barriers
- Low motivation
- Education barriers

51Insulin initiation strategies
- In general, patients are initiated on relatively
less intensive insulin regimens to ease them into
an appropriate routine. The insulin regimen can
then be intensified as needed to meet
glycemic - goals. .

57- Long-acting analogs may also possess added
benefit when compared to NPH insulin in regard to
rates of hypoglycemia and, in the case of insulin
detemir, decreased weight gain. .

60Titration
61Starting with a basal insulin analogue
- The OADs,
- including metformin and a secretagogue, are
usually retained.
62- For patients who experience dose waning toward
the end of the dosing interval, twice-daily
dosing may be considered or the administration
time for single-dose regimens can be moved to
earlier in the day during the period the patient
will be using prandial coverage or periods of
greater physical activity.

65Premixed insulin
- initiating a once-daily regimen in patients for
whom hyperglycemia is not severe and a
twice-daily regimen in patients with an AlC gt
8.5.

69Rapid-acting products
- Ideally, these agents should be administered with
a lag time before eating that is proportional to
the preprandial glucose level. The higher the
glucose level, the greater amount of time before
the meal the insulin should be administered to
allow for onset of effect and a downward trend of
premeal hyperglycemia before eating..
70Rapid-acting products
- rapid-acting insulin should be administered
earlier (e.g., 10-15 minutes before the meal) for
meals that contain primarily rapidly absorbed
carbohydrates to ensure onset during carbohydrate
absorption. Conversely, this insulin could be
administered later (e.g., at the first bite or 15
minutes after the meal) for meals with high fat
content, which may slow carbohydrate absorption..
71- Most patients start a once-daily
- regimen before dinner, while maintaining
sensitisers - and discontinuing evening secretagogues, and
- should use 12 U initially.
72- A recent study shows 41 of
- patients with type 2 diabetes attained an A1C
less than 7 on a once-daily - regimen of BIAsp 30 and OADs.
73- the addition of oncedaily biphasic insulin aspart
70/30 before the evening meal in patients failing
to meet glycemic goals on metformin resulted in
A1C reductions of 1.1-1.3.
74it is important to note that when A1C levels are
8.5 or above, initiating insulin therapy with a
twice-daily premixed insulin analogue is more
effective at achieving glycaemic control
than basal insulin.

78- Lingvay et al, recently demonstrated a 100
success rate in achieving a goal AlC of lt 7.0 in
patients with newly diagnosed type 2 diabetes by
initiating twice-daily biphasic insulin aspart
70/30 insulin in combination with metformin..
79- Patients usually remain on sensitisers
- whereas secretagogues are generally discontinued
if using two or more injections.

88Use of insulin glargine and cancer incidence in
Scotlanda study from the Scottish Diabetes
Research NetworkEpidemiology Group-Diabetologia(2
009)
- Overall, insulin glargine use
- was not associated with an increased risk of all
cancers over a 4 year time frame. - In the subgroup of insulin glargine only users
- to more likely reflect allocation bias rather
- than an effect of insulin glargine itself.
