High density lipoprotein (HDL) kinetics were studied by injecting (/sup 3/H)apoprotein A-I (apoA-I)/HDL into 12 subjects with normal glucose tolerance and 12 patients with noninsulin-dependent diabetes mellitus (NIDDM). The results indicate that the mean fractional catabolic rate (FCR) of apoA-I/HDL was significantly faster (0.63 +/- 0.07 (+/- SEM) vs. 0.39 +/- 0.02 1/day; P less than 0.001) and the apoA-I/HDL synthetic rate greater (29.4 +/- 2.9 vs. 22.9 +/- 1.3 mg/kg X day; P less than 0.02) in patients with NIDDM than in normal subjects. Furthermore, there were statistically significant inverse relationships between apoA-I/HDL FCR and plasma levels of both HDL cholesterol (r = -0.71; P less than 0.001) and apoA-I (r = -0.63; P less than 0.001). In addition, the increase in apoA-I/HDL FCR was directly related to fasting plasma glucose (r = 0.78; P less than 0.001) and insulin (r = 0.76; P less than 0.001) concentrations. These data support the view that the decrease in plasma HDL cholesterol and apoA-I levels commonly found in patients with noninsulin-dependent diabetes is due to an increase in the catabolic rate of apoA-I/HDL secondary to the defects in carbohydrate metabolism present in these patients.
