    R&D Systems ltb4 parameter assay kit
    Dysregulated lipid mediators from the AA pathway in AH patients. (A) Simplified schematic representation of the AA metabolic pathway. Key biosynthetic enzymes are shown next to arrows, lipid intermediators in box, and proinflammatory lipid mediators in red and anti-inflammatory lipid in blue. (B–F) Scatter plots showing plasma levels of <t>LTB4</t> (B, C) , PGD2 (D) , LXA4 (E) , and LTB4/LXA4 ratio (F) in healthy controls (HC), patients with alcoholic hepatitis (AH), and heavy drinking controls (HDC). Concentrations were measured by LC-MS/MS (B; open symbols) or ELISA (C-E; filled symbols). Kruskal-Wallis test with Dunn’s correction for pairwise comparison among AH, HDC, and HC. * p < 0.05, ** p < 0.01, *** p < 0.001. ns, not significant.

    Longitudinal changes in plasma levels of PGD2, LTB4, and LXA4 in AH patients at 6-month or 12-month follow-ups. Scatter plots comparing levels of PGD2 (A, B) , LTB4 (C, D) , LXA4 (E, F) , and LTB4/LXA4 ratio (G, H) at 6-month (D180) or 12-month (D360) follow-ups with baseline values (D0) in patients with alcoholic hepatitis (AH) who were abstinent during the follow ups. Wilcoxon matched pairs signed rank test was used to compare the differences between D0 and D180 (n=13) or D360 (n=9). * p < 0.05, ** p < 0.01. ns, not significant. AH, alcoholic hepatitis.
