Abstract

Insulin administration to healthy subjects inhibits the production of very low density lipoprotein (VLDL)1 (Svedbergs flotation (Sf) rate 60-400) without affecting that of VLDL2 (Sf 20-60) sub-class. This study was designed to test whether this hormonal action is impaired in non-insulin-dependent diabetes mellitus (NIDDM). We studied six men with NIDDM (age 53 +/- 3 years, body mass index 27.0 +/- 1.0 kg/m2, plasma triglycerides 1.89 +/- 0.22 mmol/l) during an 8.5 h infusion of saline (control) and then in hyperinsulinaemic (serum insulin approximately 540 pmol/l) conditions during 8.5 h infusions of glucose and insulin to give either hyper- and normoglycaemic conditions. [3-2H]-leucine was used as tracer and kinetic constants derived using a non-steady-state multicompartmental model. Compared to the control study, patients with NIDDM reduced VLDL1 apo B production by only 3 +/- 8% after 8.5 h of hyperinsulinaemia (701 +/- 102 vs 672 +/- 94 mg/day respectively, NS) in hyperglycaemic conditions and by 9 +/- 21% under normoglycaemic conditions (603 +/- 145 mg/day). In contrast, in normal subjects insulin induced a 50 +/- 15% decrement in VLDL1 apo B production (p < 0.05). Direct synthesis of VLDL2 apo B in patients with NIDDM was not markedly affected by insulin. We conclude that a contributory factor to hypertriglyceridaemia in NIDDM is the inability of insulin to inhibit acutely the release of VLDL1 from the liver, despite efficient suppression of serum nonesterfied fatty acids.

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.
