Abstract:
Objective:To explore the changes of iron metabolism in patients with hepatitis B cirrhosis and esophageal and gastric varices complicated with portal vein thrombosis.Methods:This study was a cross-sectional study. 253 patients with hepatitis B cirrhosis with esophageal and gastric varices who were hospitalized in the Zhongshan Hospital, Fudan University from January 1, 2020 to December 31, 2021 were included in this study. They were divided into portal vein thrombosis group ( n=57) and non portal vein thrombosis group ( n=196) according to the presence or absence of portal vein thrombosis. The iron metabolism characteristics of the two groups were compared, and subgroups were analyzed according to the presence or absence of ascites, platelet count level, D-dimer level, and Child grade. The factors related to portal vein thrombosis were screened through multivariate logistic regression analysis. Results:The ratio of Child pugh B/C, ascites, D-dimer and platelet count in patients with hepatitis B cirrhosis and esophageal and gastric varices complicated with portal vein thrombosis was higher (all P<0.05). Patients with portal vein thrombosis had higher levels of soluble transferrin receptor [2.4(1.8, 3.6)mg/L vs 1.8(1.3, 2.7)mg/L, P=0.006], and lower levels of ferritin [33.1(18.9, 63.3)ng/ml vs 57.7(19.4, 142.5)ng/ml, P=0.038]. Layered analysis showed that ascites, platelet count levels, D-dimer levels, and Child-pugh grade did not affect the negative correlation trend between ferritin and portal vein thrombosis, and the positive correlation trend between soluble transferrin receptors and portal vein thrombosis. Moreover, soluble transferrin receptors showed a statistically significant positive correlation with portal vein thrombosis in the absence of ascites, low D-dimer levels, and Child-pugh grade A. Multivariate analysis suggested that after weighing Child-pugh grading, platelet count, and D-dimer levels, ferritin ( OR=0.943, 95% CI: 0.904-0.983, P=0.006) and soluble transferrin receptor ( OR=1.034, 95% CI: 0.001-1.067, P=0.044) were independently associated with portal vein thrombosis. Conclusions:In patients with hepatitis B cirrhosis with esophageal and gastric varices, the characteristics of iron metabolism in patients with portal vein thrombosis are different from those in patients without thrombosis, with higher levels of soluble transferrin receptor and lower levels of ferritin.
