Urinary <i>chiro</i>-Inositol Excretion is an Index Marker of Insulin Sensitivity in Japanese Type II Diabetes

Abstract

The urinary excretion of chiro-inositol was much lower in the diabetic patients (32.3 +/- 16.0 mumol/day, means +/- SD) than in the NGT subjects (96.0 +/- 17.6; P < 0.0001) and IGT subjects (58.9 +/- 11.6; P < 0.0001). SI was much lower in the diabetic patients (3.81 +/- 1.49) than in the NGT subjects 6.30 +/- 1.59, P < 0.0005). SG was much lower in the diabetic patients (2.14 +/- 0.56) than in the NGT subjects (3.07 +/- 0.38, P < 0.0001). There was a significant correlation between urinary chiro-inositol excretion and SI (r = 0.766), as well as a significant correlation between urinary chiro-inositol excretion and SG (r = 0.747).
