The influence of continuous sc insulin infusion therapy for 6 weeks on sensitivity to insulin (euglycemic clamp technique) and hepatic glucose production (3-[3H]glucose technique) was measured in 10 type 1 diabetic patients whose mean duration of diabetes was 8 yr. Mean diurnal blood glucose fell from 8.5 +/- 0.8 (SEM) mmol/liter to 6.0 +/- 0.6 mmol/liter (P less than 0.05) and glycosylated hemoglobin from 10.5 +/- 0.4% to 8.7 +/- 0.3%. Insulin requirements declined by 23% from 47 +/- 4 U/day prepump to 36 +/- 2 U/day after 6 weeks of pump therapy (P less than 0.01). During the insulin clamp, plasma insulin was maintained at approximately 90 mU/liter and plasma glucose at approximately 5.0 mmol/liter in all studies. The rate of glucose metabolism in diabetic patients during conventional therapy (4.65 +/- 0.41 mg/kg X min) was 35% lower than in normal subjects (7.20 +/- 0.42 mg/kg X min, n = 14, P less than 0.001). After 6 weeks of pump therapy, total glucose uptake increased by 27% to 5.90 +/- 0.60 mg/kg X min, P less than 0.05 vs. prepump). This was still 18% lower than in the normal subjects (P less than 0.05). Basal hepatic glucose production in the diabetic patients during conventional therapy (3.07 +/- 0.14 mg/kg X min) was 70% higher than in the normal subjects (1.79 +/- 0.07 mg/kg X min, n = 7, P less than 0.001). After 6 weeks of pump therapy, hepatic glucose production fell to 2.48 +/- 0.19 mg/kg X min (P less than 0.05), which was still 40% higher than in the normal subjects (P less than 0.01). Basal hepatic glucose production was directly related to the fasting plasma glucose level (r = 0.67, P less than 0.001) and inversely proportional to fasting insulin concentration (r = -0.48, P less than 0.05) in the diabetic patients. Specific tracer insulin binding to erythrocytes in the diabetic patients (19.4 +/- 1.5%) was comparable to that in the normal subjects (19.6 +/- 1.2%) and remained unchanged during pump therapy. Thus the improved metabolic control resulting from pump therapy is associated with enhancement in sensitivity to insulin, and reduction in basal hepatic glucose production.
