Objective. The aim of this study was
to compare the clinical effects of a triple
oral antidiabetic combination versus basal
insulin and metformin combination
treatment in patients with poorly controlled
type 2 diabetes.
Methods. Eighty patients with type 2
diabetes, who were treated by metformin
and sulphonylurea combination, and had
HbA1c values between 7.5 and 10 % (58
and 86 mmol/L), were randomized into two
groups. The first group was given triple oral
antidiabetic therapy (pioglitazone,
metformin, and sulphonylurea) and the
second group was given metformin and a
bedtime basal insulin (insulin detemir)
combination for 12 weeks. Metabolic
parameters were evaluated.
Results. The mean fasting plasma
glucose and HbA1c levels decreased in both
groups. The decrease in HbA1c was slightly
higher in triple oral antidiabetic group
(p=0.046). The patients in triple oral
combination group gained 0.2 kg (p=0.881)
and those in the metformin-insulin detemir
combination group lost 1.7 kg (p=0.001) in
12 weeks (p=0.29 between groups). The
frequency of hypoglycemia was higher in
triple oral antidiabetic group (11 vs. 2
episodes, respectively).
Conclusion. Both sulphonyureametformin-
pioglitazone and insulin
detemir-metformin therapies provided
significant improvements in glycemic
control. However, sulphonylurea,
pioglitazone and metformin combination
led to more frequent hypoglycemic events,
and weight management seemed in favor of
insulin detemir-metformin combination.
