Abstract

Amylin is a 37-amino acid pancreatic polypeptide, probably involved in the pathophysiology of Type 2 (non-insulin-dependent) diabetes mellitus. We have determined amylin in human plasma by extraction-based radioimmunoassay (Sep-Pak C18). Of 23 healthy control subjects plasma amylin was determined as 11.9 +/- 3.5 ng/l. Of 27 patients with Type 2 diabetes receiving insulin the amylin levels were lower, and in 16 patients with Type 2 diabetes on oral medication they were higher than in the control subjects; 8.2 +/- 4.4 ng/l (p less than 0.01) vs 18.8 +/- 9.9 ng/l (p less than 0.05). In 14 Type 1 (insulin-dependent) diabetic patients we found extremely low mean amounts of amylin: 2.9 +/- 1.9 ng/l (p less than 0.002). Thus, basal amylin appears to be associated with the capacity to release insulin. An oral glucose load stimulated the release of amylin, this was more pronounced in patients with Type 2 diabetes than in healthy subjects. An excellent correlation of mean amylin with mean insulin concentrations was obtained (r = 0.949). In patients with Type 2 diabetes amylin was reduced congruent to decreases in C-peptide during a hyperinsulinaemic, euglycaemic glucose clamp experiment (r = 0.971 for linear correlation between C-peptide levels and amylin). We conclude, that amylin and insulin are co-secreted in humans, and that the amylin release is under feedback-control by insulin.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Circulating amylin levels are higher in humans and animal models of obesity and type 2 diabetes.

    “Higher levels of circulating amylin were found in humans and animal models of obesity and type 2 diabetes (24, 88, 151, 184).”

    From The Activity of Peptides of the Calcitonin Family in Bone (2019) · cites this paper as [88]

    The section on plasma amylin concentrations reports higher levels in humans with type 2 diabetes taking oral medication than in healthy controls, but lower levels in those receiving insulin (page unavailable). The paper does not report circulating amylin levels in obesity or animal models, so it supports only part of the cited statement. (LLM, conf=0.90)

  • Amylin suppresses postprandial glucagon and delays gastric emptying.

    “It suppresses postprandial glucagon and delays gastric emptying (46).”

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.
