BACKGROUND AND AIM: Comprehensive investigations on the prothrombotic factors of splanchnic vein thrombosis (SVT), including Budd-Chiari syndrome (BCS) and non-cirrhotic nonmalignant portal vein thrombosis (PVT), in Eastern patients are scarce.
METHODS: Between March 2012 and July 2017, 812 consecutive patients, including 418 BCS and 394 non-cirrhotic nonmalignant PVT patients, were admitted to Xijing Hospital (a Chinese tertiary academic hospital) and screened for prothrombotic factors. Odds ratios (ORs), 95% confidence intervals (CIs), and P-trends were calculated by using conditional logistic regression.
RESULTS: The prevalence of myeloproliferative neoplasms (MPNs) was only 6.3% among BCS patients but 28.3% among PVT patients. Notably, the presence of MPNs was associated with a higher risk of hepatic vein-type BCS (OR 9.9, 95% CI 3.6-26.7, P-trend < 0.001) and extensive thrombosis in PVT (OR 4.1, 95% CI 1.9-8.9, P-trend < 0.001). Calreticulin mutations existed in 2.7% of SVT patients. Furthermore, the prevalence of antiphospholipid antibody syndrome and protein C, protein S, or antithrombin deficiency in BCS patients was 7.3% and 22.5%, respectively, similar to that in patients with PVT (7.4% and 25.7%). In addition, factor V Leiden mutation, prothrombin G20210A mutation, and paroxysmal nocturnal hemoglobinuria were identified in < 1% of both BCS and PVT patients.
CONCLUSION: There is a significant positive association between MPNs and hepatic vein-type BCS or non-cirrhotic nonmalignant PVT with extensive thrombosis. Additionally, calreticulin mutations should be tested in JAK2V617F -negative SVT patients in China. However, screening for factor V Leiden mutation, prothrombin G20210A mutation, and paroxysmal nocturnal hemoglobinuria may be unnecessary.
