All subjects underwent tests for the determination of oral glucose tolerance, ultradian oscillations in insulin secretion during a 28-h glucose infusion, insulin secretion in response to intravenous glucose, glucose disappearance after intravenous glucose (Kg), and insulin sensitivity (SI) as measured by the Bergman minimal model method.

It has occasionally been suggested that GH directly suppresses circulating IGFBP-1 levels, although it is generally believed that such an effect is secondary to a GH-induced increase in insulin levels.

GH bolus caused a small but significant decrease in plasma IGFBP-1 concentrations without changes in insulin [IGFBP-1 (microgram/l): 2.6 +/- 0.3 (GH) vs 3.2 +/- 0.4 (placebo), P < 0.05].

Conversely, a 28-h somatostatin infusion with and without GH administration during fasting in normal subjects yielded higher IGFBP-1 levels in the non-GH substituted study [50.5 +/- 5.3 (GH-suppression) vs 22.6 +/- 5.6 (GH-substitution), P < 0.01], comparable with an increased concentration of IGFBP-1 during fasting in GH-deficient patients without usual GH substitution [23.4 +/- 7.6 (GH pause) vs 14.1 +/- 4.9 (GH substitution), P < 0.01].

Finally, a significant rebound increase in IGFBP-1 level in response to insulin induced hypoglycemia was only observed among GH-deficient patients, but not in control subjects, the latter of whom responded to hypoglycemia with a significant increase in serum GH levels [23.2 +/- 7.2 (GHDA) vs 2.5 +/- 0.3 (controls), P < 0.01].

In conclusion, a suppressive effect of GH on IGFBP-1 appears to be unmasked in the presence of low or suppressed insulin levels, making GH a potential regulator of IGF-1 bioactivity in a hitherto unrecognized way.
