Background And PurposeEmerging researches have regarded serum chloride as a capable predictor of mortality in liver cirrhosis. We aim to investigate the clinical role of admission chloride in cirrhotic patients with esophagogastric varices receiving transjugular intrahepatic portosystemic shunt (TIPS), which is unclear.MethodsWe retrospectively analyzed data of cirrhotic patients with esophagogastric varices undergoing TIPS in Zhongnan Hospital of Wuhan University. Mortality outcome was obtained by following up for 1-year after TIPS. Univariate and multivariate Cox regression were used to identify independent predictors of 1-year mortality post-TIPS. The receiver operating characteristic (ROC) curves were adopted to assess the predictive ability of the predictors. In addition, log-rank test and Kaplan-Meier (KM) analyses were employed to evaluate the prognostic value of predictors in the survival probability.ResultsA total of 182 patients were included ultimately. Age, fever symptom, platelet-to lymphocyte-ratio (PLR), lymphocyte-to-monocyte ratio (LMR), total bilirubin, serum sodium, chloride, and Child-Pugh score were related to 1-year follow-up mortality. In multivariate Cox regression analysis, serum chloride (HR = 0.823, 95%CI = 0.757-0.894, p < 0.001) and Child-Pugh score (HR = 1.401, 95%CI = 1.151-1.704, p = 0.001) were identified as independent predictors of 1-year mortality. Patients with serum chloride <107.35 mmol/L showed worse survival probability than those with serum chloride ≥107.35 mmol/L no matter with or without ascites (p < 0.05).ConclusionAdmission hypochloremia and increasing Child-Pugh score are independent predictors of 1-year mortality in cirrhotic patients with esophagogastric varices receiving TIPS.Copyright © 2023 Formosan Medical Association.
