Abstract
Plasma insulin response to oral glucose, insulin resistance, and insulin suppression of hepatic glucose production were studied in 11 normal subjects and 11 hypertriglyceridaemic patients. Patients with hypertriglyceridaemia had a significantly higher insulin response to oral glucose. Insulin resistance was also significantly greater in hypertriglyceridaemic subjects as determined by measuring the steady-state plasma glucose response during a continuous infusion of epinephrine, propranolol, glucose, and exogenous insulin. Insulin suppression of hepatic glucose production was calculated from the results of two studies in which glucose turnover rate was measured by a continuous infusion of3H-2-glucose. The first study was performed under conditions of basal insulin secretion, and the second carried out at steady state exogenous insulin levels of approximately 100 μU/ml. The results indicated that basal hepatic glucose production was the same in both groups, and was suppressed to an equal degree by physiological levels of insulin. These data demonstrate that hepatic glucose production can be suppressed to an equal degree in normal and hypertriglyceridaemic subjects at comparable circulating insulin levels, at the same time that resistance to insulin-stimulated glucose uptake is observed in the hypertriglyceridaemic individuals.This publication has 11 references indexed in Scilit:
