In Praise of the Hyperglycemic Clamp: A method for assessment of β-cell sensitivity and insulin resistance
Abstract
The most widely used methods for the assessment of beta-cell response and peripheral tissue sensitivity to insulin include the oral glucose tolerance test (OGTT), the frequently sampled intravenous glucose tolerance test, and the hyperinsulinemiceuglycemic clamp technique. During an OGTT, glucose levels increase after a variable lag period, then reach a peak and fall variably among individuals. The response even varies in the same subject upon repeat testing. A more reproducible glucose curve is achieved with an intravenous glucose tolerance test in which the plasma glucose levels rise rapidly to a very high level and fall exponentially. In neither of the two methods is a steady-state glucose level achieved. In the hyperinsulinemic-euglycemic clamp technique, a steady-state glucose level can be maintained at any level of hyperinsulinemia. However, an assessment of beta-cell sensitivity is not obtained. The less used hyperglycemic clamp technique can assess beta-cell sensitivity as well as peripheral tissue sensitivity. Moreover, a measure of glucose effectiveness or non-insulin-mediated glucose uptake can also be determined. With this technique the beta-cells of all subjects are stimulated with the same arterial glucose concentration, thus enabling assessment of beta-cell response to identical plasma glucose levels. Comparison of responses to stable hyperglycemic stimuli can be made in glucose-tolerant and -intolerant states with the addition of various substances, either alone or in combination. The use of the hyperglycemic clamp and several of its variant forms is reviewed as an alternative method for assessment of glucose homeostasis.

“Although not as accurate as euglycemic hyperinsulinemic clamps for measuring insulin sensitivity, GIR during steady-state hyperglycemia (i.e., 60–90 min) allows a fairly good direct measurement of insulin sensitivity (34).”

“The insulin response to square-wave–induced hyperglycemia is bimodal: there is a first-phase insulin secretion that occurs during the first 10 minutes with a peak response at ≈4 minutes; then, plasma insulin level falls reaching a nadir at ≈10 minutes; next, the second insulin secretion phase begins and insulin levels…”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
