Abstract

OBJECTIVE—To determine whether, over daytime, one or several hyperglycemic excursions exist that can be general failures in the glycemic control of patients with type 2 diabetes. RESEARCH DESIGN AND METHODS—In 200 non–insulin-using patients with type 2 diabetes, diurnal plasma glucose and insulin profiles were studied. Plasma glucose concentrations were measured after an overnight fast (at 8:00 a.m. immediately before breakfast), during the postprandial period (at 11:00 a.m. and 2:00 p.m.), and during the postabsorptive period (at 5:00 p.m., extended postlunch time). RESULTS—In the population considered as a whole, prelunch glucose concentrations (12.0 mmol/l) were found to be significantly increased (P < 0.0001) when compared with those observed at 8:00 a.m. (8.8 mmol/l), at 2:00 p.m. (10.5 mmol/l), and at 5:00 p.m. (8.6 mmol/l). Similar significant excursions (P < 0.0001) in prelunch glucose were observed within subsets of patients selected from the following criteria: 1) body weight, 2) HbA1c, 3) categories of treatment, and 4) residual β-cell function. From the calculation of areas under the daytime glucose curves, the relative contributions of postprandial and fasting glucose to the total glucose increment were found to be similar. CONCLUSIONS—High plasma glucose excursions over morning periods seem to be a permanent failure in non–insulin-using patients with type 2 diabetes, whatever the clinical (BMI), biological (HbA1c), therapeutic, and pathophysiological (residual β-cell function) status. Midmorning glucose testing should be recommended for detecting such abnormalities and for correcting them with appropriate therapies.

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.
