Abstract

Objective To investigate the role of the Janus tyrosine kinase (JAK)- signal transducer and activators of transcription (STAT) signaling pathway in thrombosis formation after splenectomy in cirrhotic patients with portal hypertension. Methods A total of 198 liver cirrhosis patients with portal hypertension who underwent splenectomy and devascularization were recruited from March 2018 to April 2020 and then divided into thrombosis (n=41) and non-thrombosis groups (n=157) according to whether portal vein thrombosis occurred 3 months after surgery. mRNA levels of JAK2 and STAT3 in peripheral blood mononuclear cells (PBMCs) were assessed. Comparison of continuous data between groups was performed using t test, while comparison of categorial data between group was performed using chi square test. Clinicopathological data from patients were collected and analyzed for the potential risk factors of portal vein thrombosis by using univariate and multivariate Logistic regression analyses. The prediction values of JAK2 and STAT3 mRNA for portal vein thrombosis were evaluated by area under the receiver operating curve (AUC). Results The diameter of portal vein, the diameter of portal vein, the velocity difference of portal vein and the volume of spleen in the thrombus group were significantly higher than those in the non-thrombus group (t=4.718, 3.945, 8.671, and 2.006 respectively; P < 0.05).The relative mRNA levels of JAK2 and STAT3 in PBMCs of the two groups were significantly increased after surgery (t=12.933, 15.442, 14.386, 10.896; P < 0.05), and their levels were also much higher in the thrombosis group than in the non-thrombosis group of patients (P < 0.05). Multivariate Logistic regression analytic data showed that the portal vein diameter, the velocity difference of portal vein and mRNA level of JAK2 and STAT3 were all predictors for thrombosis in these patients (P < 0.05). The AUC of JAK2 and STAT3 mRNAs was 0.850 and 0.787, respectively in diagnosis of thrombosis in these patients. Conclusion The JAK / STAT signaling was activated in the process of thrombosis after splenectomy in cirrhotic patients with portal hypertension, which may be one of the important mechanisms of postoperative portal vein thrombosis, and may become a potential target for the prevention and treatment of postoperative portal vein thrombosis.
