We aimed to assess the accuracy of three promising circulating biomarkers for diagnosing AMI—citrulline, intestinal fatty acid-binding protein (I-FABP), and D-lactate. A cross-sectional diagnostic study enrolled AMI patients admitted to the intestinal stroke center and controls with acute abdominal pain of another origin. We included 129 patients—50 AMI and 79 controls. Plasma citrulline concentrations were significantly lower in AMI patients compared to the controls [15.3 μmol/L (12.0–26.0) vs. 23.3 μmol/L (18.3–29.8), p = 0.001]. However, the area under the receiver operating curves (AUROC) for the diagnosis of AMI by Citrulline was low: 0.68 (95% confidence interval = 0.58–0.78). No statistical difference was found in plasma I-FABP and plasma D-lactate concentrations between the AMI and control groups, with an AUROC of 0.44, and 0.40, respectively. In this large cross-sectional study, citrulline, I-FABP, and D-lactate failed to differentiate patients with AMI from patients with acute abdominal pain of another origin. Further research should focus on the discovery of new biomarkers.Grants from MSD-Avenir and APHP funded the SURVIBIO study; Alexandre Nuzzo received Ph.D. Grants from “Fondation de l'Avenir” and the French Gastroenterology Society (SNFGE)
Acute extrahepatic infectious or inflammatory diseases are a cause of transient mosaic pattern on CT and MR imaging related to sinusoidal dilatation of the liver
Purpose: To report the association of a mosaic enhancement pattern on contrast-enhanced CT or MR imaging and hepatic sinusoidal dilatation (SD) with acute inflammatory conditions affecting extrahepatic organs. Methods: From 2007 to 2012, patients with acute inflammatory diseases who underwent contrast-enhanced CT and/or MRI of the liver with a mosaic enhancement pattern were selected. Clinico-biological and other imaging features were collected at diagnosis and during follow-up. Results: Sixteen patients were included (15 women, median age 27\ua0years; range 18\u201368). Five women (33\ua0%) were receiving oral contraceptives. Acute inflammatory diseases included pyelonephritis (n = 10), pancreatitis (n = 2), pneumonia (n = 1), septicemia (n = 1), active Crohn's disease (n = 1), and infectious colitis (n = 1). Median white blood cell count was 13,250 cells/\u3bcL (range 11,500-18,000 cells/\u3bcL) and CRP level 94\ua0mg/L (range 60\u2013121\ua0mg/L). Mosaic enhancement pattern was present in the whole liver and was prominent in the subcapsular areas. Four patients underwent liver biopsy confirming SD. Eleven patients underwent follow-up imaging showing normalized aspect in 9/11 patients after a median of 2\ua0months. Conclusion: Acute diseases of extrahepatic organs, associated with a marked systemic inflammatory syndrome should be added to the list of conditions causing a reversible hepatic sinusoidal dilatation as manifested by a mosaic enhancement pattern on contrast-enhanced CT or MR imaging. Key Points: \u2022 Acute extrahepatic infectious/inflammatory diseases are a cause of transient MP. \u2022 In most patients, MP was seen during both arterial and portal venous phase. \u2022 In all patients, the mosaic enhancement pattern was diffuse, but more conspicuous in subcapsular areas. \u2022 MP was no longer seen after resolution of the acute disease. \u2022 No liver biopsy should be performed
