Insulin Pump Is
As Effective As Multiple Insulin Injections
CSII was as safe and effective as MDI in patients
with type 2 diabetes and may be preferable to
injections for patients who require intensive
insulin treatment.
A group of researchers led by Dr Philip Raskin
of the University of Texas in Dallas, USA, conducted
an open-label, randomized study to compare the
effects of continuous subcutaneous insulin infusion
(CSII) using insulin aspart with multiple daily
injections (MDI) of insulin. A total of 132 patients
with type 2 diabetes and no prior CSII treatment
were randomized to 24 weeks of CSII or MDI. The
researchers assessed efficacy with concentrations
of HbA1c and 8-point blood glucose profiles. Adverse
events, hypoglycaemic episodes and findings from
laboratory and physical examinations were recorded
to assess safety. Treatment satisfaction among
patients was measured in a self-administered questionnaire.
The researchers found that HbA1c decreased similarly
from baseline to the end of the study in patients
treated with CSII (from 8.2% to 7.6%) and MDI
(from 8.0% to 7.5%). The 8-point blood glucose
values were lower in patients treated with CSII
at most time points and were significantly lower
90 minutes after breakfast (167mg/dL versus 192mg/dL,
p=0.019). Safety outcomes were similar in both
treatment groups. Most patients (93%) preferred
CSII to their previous injectable insulin because
of its convenience, flexibility and ease of use.
The researchers conclude that CSII was as safe
and effective as MDI in patients with type 2 diabetes
and may be preferable to injections for patients
who require intensive insulin treatment.
