RE: [IP] A1c - 5.5 on MDI vs 5.5 on Pump
I'm still digging the journal reference, my endo is one of the team who
developed/is developing the Edmonton protocol here in Edmonton. There are
several variables in regards to these discussions that mant people seem to
be lumping together and/or disregarding. These include everything from
blood pressude characteristics to variability of a persond schedule.
A research study seeks to limit changes in many variables to focus on a
particular facet that has been deemed important. Some researcher choosing
different variables than another researcher can often be the source of
contradictions between studies that appear to be the same in their method.
In regards to your son, it is highly likely that he has a rather
erratic schedule/eating habits. HUGE assumption on my part not knowing his
age/lifestyle etc. but for my part THIS is the reason a pump is useful for
me. But remember, one of the points made in the studies was that lifestyle
was deemed to be the major source of difference in effectiveness of pump
versus MDI therapies. Am I saying "No matter what MDI is as good/better
than pumping."? Heck no, read carefully. "DEPENDING ON FACTORS INCLUDING
BUT NOT LIMITED TO LIFESTYLE, PUMP THERAPY MAY NOT BE BETTER THAN MDI FOR
CERTAIN INDIVIDUALS". Remember, individuals are not a statement of
generality for an entire population but rather an acknowledgement that
investigation and testing is required before arbitrarily making any
statement about which treatment is better. Without taking all the factors
into account (which is supposed to be the job of your endo/specialist) it is
anecdotal and irresponsible of us to try.

Studies are only as good as the sources that did them. So your memory of
unnamed sources is not a huge endorsement to me. I can also say that I have
read studies and pulling from my memory, these studies show that pumps help
to maintain more normal blood glucose levels. Also, I have done my own
personal study (sample of 1) and can assure you in my son's case the pump is
a vastly improved method of delivering insulin. Just to see his basal
profile shows this. His lowest basal is .15 and the largest is .6 It would
take a TREMENDOUS amount of testing and shots to provide for stable bgs for
him. When I add sports into the picture, and the use of temporary basals,
the superiority of CSII is really evident. I know that at in least some of
the islet transplant centers, it is a requirement that patients use pumps.
This thread seems to have changed from "are pumps a medical necessity" to
"MDI can be just as good as pumps." It can't.
Not just my opinion.
