The value of new inflammation index in predicting portal vein thrombosis in cirrhotic patients with portal hypertension / 中国医师杂志

ABSTRACT

Objective:To explore the value of a new inflammatory index in predicting portal vein thrombosis in cirrhotic patients with Portal hypertension.Methods:This study was a single center cross-sectional study. The patients with portal hypertension who underwent portal vein computed tomography (CT) examination and hepatic vein pressure gradient (HVPG) measurement in the Minhang District Central Hospital of Shanghai from January 2019 to February 2023 due to cirrhosis were included. They were divided into thrombosis group and non thrombosis group according to whether portal vein thrombosis was combined or not. The predictive value of Monocyte lymphocyte ratio (MLR), neutrophil lymphocyte ratio (NLR), platelet lymphocyte ratio (PLR) and systemic immune inflammatory index (SII) for portal vein thrombosis was determined by logistic regression analysis and receiver operating characteristic (ROC) curve.Results:A total of 122 patients were ultimately included and were divided into a thrombus group of 20 and a non thrombus group of 102 based on portal vein CT results. The MLR and PLR of patients in the thrombotic group were significantly higher than those in the non thrombotic group ( P=0.038 7, P=0.040 7). There was no significant difference in hemoglobin, platelets, leukocytes, neutrophils, lymphocytes, monocyte, NLR, SII, albumin, alanine aminotransferase (ALT), total bilirubin, creatinine, prothrombin time, D-dimer, and C-reactive protein between the two groups (all P>0.05). The diagnosis model of portal vein thrombosis was constructed by logistic regression model. It was found that the area under the ROC of MLR combined with D-dimer and ascites was 0.900, the sensitivity was 0.850, and the specificity was 0.431. Conclusions:The new inflammatory index (including MLR and PLR) is significantly increased in cirrhotic patients with portal vein thrombosis. MLR combined with D-dimer and ascites can predict portal vein thrombosis in cirrhotic patients.
