I am sure all of us could all come up
with favorites for the American Diabetes Association to do, but being
a group by and for doctors, I doubt we will see changes that we wish
would happen.
I have seen several bloggers use the
term “Stage 1” to mean prediabetes and “Stage 2” for type 2
diabetes. Yet none go as far as Brenda Bell did in her Tuesday, April 20, 2010 blog. I have lifted this from her blog and thank her
for this, even though I did not appreciate it at the time. While I
am at it, I sincerely wish she would do more blogging, as she was
often enlightening before other bloggers even thought about it.
Quote: An initial straw man
chart can be derived from the American Association of Clinical
Endrocrinologists' Medical Guidelines for Clinical Practice for the
Management of Diabetes Mellitus (2007) examples for initial
pharmacotherapy of T2DM:
Classification of Type 2 Diabetes
Mellitus (based on initial therapy algorithms)
Progression Level |
HbA1c (untreated) |
---|---|
Stage 1 (Prediabetes) |
5.7 - 6.4
|
Stage 2 |
6.5 - 7.0
|
Stage 3 |
7.0 - 8.0
|
Stage 4 |
8.0 - 10.0
|
Stage 5 |
> 10.0
|
Other issues that play into determining the progression of T2DM include the deterioration of endogenous insulin production, the development of complications of diabetes, and the degree to which a person's blood glucose levels and HbA1c are responsive to pharmacotherapy. A more complex table of progression might include these in a manner such as this:
Classifications of Type 2 Diabetes
Mellitus (proposed)
Level |
HbA1c (Goal)1 |
Effective Therapy |
Evidence of Complications |
c-peptide (relative) |
---|---|---|---|---|
Stage 1 (Pre-Diabetes)2 |
< 6.03 |
ILM. Oral medication optional for aggressive treatment. |
none |
high |
Stage 2 |
< 6.5 |
Oral medication and/or insulin sensitizer required |
none |
high |
Stage 3 |
< 7.0 |
Combination therapy and/or insulin required |
possible; possible comorbid conditions |
varies |
Stage 4 |
< 7.0 |
Insulin therapy required, with or without oral medications
and/or pramlintide (Symlin) |
probable; possible comorbid conditions |
low |
Stage 5 |
< 8.0 |
Intensive insulin therapy required, possibly in conjunction
with insulin sensitizers |
obvious; one or more comorbid conditions |
low |
1 While the HbA1c
goals at the more advanced levels of diabetes progression are high
enough that complications are likely to develop or intensify, those
goals may not be realistically achievable with current medical and
pharmaceutical technology.
2 Includes all
previous diagnoses of gestational diabetes or Type 2 diabetes in
which pharmacotherapy is not currently indicated
3 More aggressive
practitioners may argue for an HbA1c goal of under 5.5 for Stage 1,
under 6.0 for Stage 2, and under 6.5 for later stages of T2DM. The
less-aggressive goals are informed in part by the (ACCORD) study, in
which the tested combination therapy suggested a higher mortality
risk for intensive control.
A classification scheme of this sort may remove the ambiguity of a diagnosis of "prediabetes" and its associated laissez-faire ("It's not diabetes") attitude, as well as the popular belief that once diagnosed, one can become "undiagnosed" (or perhaps "de-diagnosed"). It can also alert a medical practitioner to the need for ongoing monitoring and assessment of a person's glucose metabolism. On the other hand, classification will add to the pool of people indicated to have diabetes those who do not consider themselves to be currently affected by diabetes -- and in an environment where a positive diagnosis can mean the denial of employment, medical insurance, or healthcare, this can have worse repercussions than living with undiagnosed or untreated Stage 1 (or even Stage 2) T2DM.

The above quoted information is the
most comprehensive that I have seen and I wish the ADA would give
this consideration.
