Abstract

BACKGROUND: There are a few limitations in application of staged diabetes management (SDM) program to Korean type 2 diabetic patients because of their unique characteristics, such as non-obese but centrally obese anthropometry and variable relationships between insulin secretion and insulin resistance compared to western diabetic patients. Therefore, we proposed new therapeutic model which considers ethnic characteristics and assesses patient by insulin secretion and insulin resistance.
METHODS
We have previously assessed patient's insulin secretion by serum fasting C-peptide level and insulin resistance by insulin tolerance test (ITT) and proposed new therapeutic model: by cut-off value of 2.5%/min in insulin resistance and 1.1 ng/dL, 1.7 ng/dL in insulin secretion.
RESULTS
Total 183 patients were enrolled in this program and 59% of total subjects had to change the treatment modality according to this new therapeutic model. Mean fasting glucose level dropped from 177.0+/-38.6 mg/dL (9.83+/-2.14 mmol/L) to 148.2+/-31.2 mg/dL (8.23+/-1.73 mmol/L) (p<0.001), mean postprandial 2 hour glucose level dropped from 255.6+/-60.1 mg/dL (14.19+/-3.34 mmol/L) to 221.1+/-58.4 mg/dL (12.27+/-3.24 mmol/L) (p<0.001), mean HbA1c level dropped from 8.37+/-1.42% to 7.72+/-1.39% (p<0.001) even though baseline group already received conventional treatment. 51.4% of the post-treatment group achieved a HbA1c valued of less than 7.5% compared to 28.4% of the pre-treatment group.
CONCLUSION
The new standardized therapeutic model strongly suggests its valuable clinical application in Korean type 2 diabetic patients.
