Abstract

Nonspecific investigations resulting in treatment delays contribute to the 30 per cent mortality associated with acute mesenteric ischemia (AMI). As preliminary studies indicate that α-glutathione S-transferase (α-GST) is elevated in AMI we compare the ability of a-GST against conventional biochemical tests to predict AMI. There were 58 patients prospectively evaluated for AMI. Samples for α-GST (Biotrin International, Dublin, Ireland), lactate, pH, amylase, base excess, and white blood cell count (WBC) were evaluated. Intestinal ischemia was confirmed by colonoscopy, angiography, or laparotomy. Ischemia was present in 35 (60%) patients: small bowel (n = 14), colonic (n = 17), and global (n = 4). Four patients without autopsy were excluded. α-GST was elevated in those with AMI [22.2 (7–126) ng/mL vs 2.2 (1–3) ( P = 0.001)]. α-GST was more accurate at predicting intestinal ischemia (74%) than conventional tests (47–69% accuracy). Accuracy was increased to 80 per cent by combination with lactate or WBC, which increased sensitivity to 97 to 100 per cent. α-GST monitoring is a useful tool for the diagnosis of intestinal ischemia. A normal α-GST and WBC may exclude the presence of AMI.

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.
