Parenterally administered dipeptide alanyl-glutamine prevents worsening of insulin sensitivity in multiple-trauma patients
Abstract
BACKGROUND: Dipeptide alanyl-glutamine is a commonly used substrate in major trauma patients. Its importance and effects are widely discussed; as yet, it has not been elucidated whether its administration influences glucose homeostasis. OBJECTIVE: We studied the effect of alanyl-glutamine administration on insulin resistance. DESIGN: Prospective, randomized, controlled trial. SETTING: Intensive care unit of a tertiary level hospital. PATIENTS: Multiple-trauma patients. INTERVENTIONS: Patients were randomized into two groups and assigned to receive parenterally an equal dose of amino acids either with alanyl-glutamine in the dose of 0.4 g x kg body weight(-1) x 24 hrs(-1) (group AG) or without alanyl-glutamine (control group C). This regimen started 24 hrs after injury and continued for 7 days. To assess insulin sensitivity, we performed an euglycemic clamp on day 4 and day 8 after injury. MEASUREMENTS AND MAIN RESULTS: We randomized 40 patients, 20 into each group. At day 4, insulin-mediated glucose disposal was higher in group AG (2.4 +/- 0.7 mg x kg(-1) x min(-1) glucose), with significant difference from group C (1.9 +/- 0.6 mg x kg(-1) x min(-1), p = .044). At day 8, glucose disposal was higher in group AG (2.2 +/- 0.7 mg x kg(-1) x min(-1) glucose), with significant difference in comparison with group C (1.2 +/- 0.6, p < .001). Diminution of the main glucose homeostasis variables in group C between days 4 and 8 of the study was statistically significant (p < .001); however, differences in these variables in group AG were without statistical significance. CONCLUSIONS: Parenteral supplementation of alanyl-glutamine dipeptide was associated with better insulin sensitivity in multiple-trauma patients.

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.
