| Abstract |
Purpose
: We investigated the clinical characteristics of IDDM patients, treated with NPH only, and evaluated current problems by measurement of serial blood glucose, insulin, C-peptide for 12 hours after administration of intermediate-acting insulin.
Methods
: We studied 19 IDDM patients who had been diagnosed and followed up on a
regular basis at Severance hospital. They were assigned into 2 groups, one(HbA1c high group) with HbA1c above 12%, the other(HbA1c low group) showing HbA1c below 12%. Their Heights, DM durations, HbA1c, basal C-peptides were primarily measured. Using continuous withdrawal pump, samples were taken every hour for 12 hours from 7:00 am. And serial blood glucose, insulin, C-peptide were assayed.
Results
:
1) The mean HbA1c of the high group was 16.5±3.5% and that of the low group was
11.0±0.6%. There were no differences in clinical characteristics.
2) In HbA1c high group, fasting blood glucose, and mean blood glucose levels for 3hours were 156±85mg%, 284±125mg%(8,9,10am), 250±133mg%(11,12am,1pm), 252±122mg%(2,3,4pm), and 182±105 mg%(5,6,7pm), respectively. In low group, fasting blood glucose, and mean blood glucose levels for 3hours were 130±71mg%, 275±109 mg%(8,9,10am), 249±129mg%(11,12am,1pm), 231±81mg%(2,3,4pm), 158±62mg%(5,6,7pm), respectively.
3) Fasting blood insulin level was 51±47μU/l in high group, 62±62μU/l in low group. Thereafter low HbA1c group showed higher insulin levels than high HbA1c group.
4) Fasting blood C-peptide was 0.16±0.20μg/l in the high group, and 0.34±0.14μg/l in low group. Thereafter low group developed higher C-peptide responses than high group. The curve of C-peptide showed similar change of blood glucose, and maximal response followed 1-2 hours after maximal level of blood glucose.
Conclusion
: We concluded that short-acting insulin should be included for good control of blood glucose. Although fasting & dinner blood sugar seemed to be under fair control, intermediate-acting insulin used alone was not effective in preventing severe blood sugar elevation after morning meal. |
