Glucose, Advanced Glycation End Products, and Diabetes Complications: What Is New and What Works

Abstract

Editor’s note: This is one in a series of articles from the various professional section councils of the American Diabetes Association. This installment is from the Council on Complications. The incidence of diabetes, particularly type 2 diabetes, is increasing at an alarming rate. Worldwide, about 124 million people had diabetes by1997; by 2010, this number is estimated to reach 221 million. Because of the large number of severe pathologies complicating the clinical course of diabetes, one can easily speculate on the huge economic and psychosocial impact of diabetes across age groups and geographical regions. A large number of studies have focused on the factors involved in the pathogenesis of diabetic complications, most seeking effective therapies, but the exact cellular or molecular basis of these complications has not yet been fully elucidated. Hyperglycemia is still considered the principal cause of diabetes complications. Its deleterious effects are attributable, among other things, to the formation of sugar-derived substances called advanced glycation end products (AGEs). AGEs form at a constant but slow rate in the normal body, starting in early embryonic development, and accumulate with time. However, their formation is markedly accelerated in diabetes because of the increased availability of glucose. AGEs are a heterogeneous group of molecules formed from the nonenzymatic reaction of reducing sugars with free amino groups of proteins, lipids, and nucleic acids. The initial product of this reaction is called a Schiff base, which spontaneously rearranges itself into an Amadori product, as is the case of the well-known hemoglobin A1c (A1C). These initial reactions are reversible depending on the concentration of the reactants. A lowered glucose concentration will unhook the sugars from the amino groups to which they are attached; conversely, high glucose …

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

  • Endogenous AGEs are produced and slowly accumulated within the body during normal aging and under oxidative stress, inflammatory, and hyperglycemic conditions often observed in diabetes and other metabolic syndromes.

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.
