Systemic inflammation and portal vein thrombosis in cirrhotic patients with gastroesophageal varices.

Abstract

BACKGROUND AND AIM:

Cirrhotic patients with gastroesophageal varices and non-tumoral portal vein thrombosis have a higher risk of re-bleeding and poor prognosis. This study aimed to analyze inflammatory biomarkers and thromboelastography in cirrhotic patients with portal vein thrombosis.

METHODS:

A total of 385 consecutive cirrhotic patients with gastroesophageal varices were prospectively enrolled between 1 December 2016, and 31 August 2017. Of these, 231 were eligible for analysis and were divided into portal vein thrombosis (n = 103) and non-portal vein thrombosis (n = 128) groups based on computerized tomography angiography findings.

RESULTS:

Patients with portal vein thrombosis generally had higher Child-Pugh scores than those without portal vein thrombosis (6.38 ± 0.12 vs. 5.81 ± 0.09, P < 0.001). The serum albumin levels were significantly lower in patients with portal vein thrombosis (35.90 ± 0.52 vs. 38.52 ± 0.43, P < 0.001). The portal vein thrombosis group had significant higher serum levels of interleukin 6 [4.85 (3.15-6.99) vs. 3.09 (2.06-5.20) pg/ml, P < 0.001] and tumor necrosis factor alpha [10.70 (7.60-15.20) vs. 9.07 (7.03-11.60) pg/ml, P = 0.020]. The interleukin 6 level was 2.5-fold higher in patients with portal vein thrombosis (adjusted odds ratio: 2.574; 95% confidential interval: 1.248-5.310). Thromboelastography showed that TEG-R, the reaction time, was significantly lower in the portal vein thrombosis group [5.20 (4.80-6.30) vs. 6.00 (5.20-6.95), P = 0.009], indicating enhanced coagulation activity.

CONCLUSION:

This study confirmed the important role of systemic inflammation in portal vein thrombosis. Interleukin 6, an important inflammatory cytokine, is independently associated with portal vein thrombosis. The correlation between the interleukin 6 level and portal vein thrombosis requires further investigation.
