Prompt metabolic control improvement and daily
insulin requirement assessment are indications for short-term intensive
insulin therapy in
type 2 diabetes, applied as multiple daily subcutaneous
insulin injections (MDI), continuous subcutaneous (CSII) and intravenous
insulin infusion (IVII). The study aimed at assessing the mean daily
insulin dosage before beginning and after finishing three methods of short-term intensive
insulin therapy, discontinued upon achievement of good
glycemic control. 90 poorly controlled
type 2 diabetes patients, hospitalized in Diabetology Department of Medical University in Lódź, treated with
insulin twice daily were enrolled into the study (age 52.8 +/- 6.7 years, mean daily
insulin dosage 0.76 +/- 0.28 U.I./kg. of
body weight, daily
blood glucose profile values 271 +/- 76 mg/dl). The patients were randomized into three groups: the first group treated with MDI, the second with IVII and the third with CSII.
Insulin dosage increased significantly after MDI
therapy comparing with prehospital values (0.72 U.I./ kg-->0.84 U.I./kg, p = 0.007). No change in daily
insulin requirement was noted in CSII and IVII groups. We concluded that CSII and IVII comparing with MDI are more efficient methods of achieving prompt
glucose control improvement and they do not lead to the increase in the
insulin dosage.
