ABSTRACT

OBJECTIVE@#Hepatic veno-occlusive disease (HVOD) has attracted increasing attention in recent years due to its relationship with ingestion of Gynura segetum. The mortality of severe HVOD remains high due to the lack of specific therapies. The aim of the study was to delineate the clinical characteristics and outcomes and explore the potential prognostic factors of HVOD.@*METHODS@#This was a single-center retrospective study. Eighty-nine HVOD patients were screened from the First Affiliated Hospital of Zhejiang University with an ingestion history of G. segetum before developing symptoms from January 2009 to May 2018. The enrolled patients were divided into the survivor and death groups according to the clinical follow-up that ended on September 1, 2019. The demographic variables and clinical data of the patients were recorded. A binary logistic regression analysis and receiver operating characteristic curve were conducted to identify the prognostic factors and assess the prognostic value for predicting death, and a survival analysis was performed to evaluate the clinical outcomes.@*RESULTS@#Sixty-four patients were eligible for further analysis. Most patients showed abdominal distension and were positive for migrating dullness in the abdomen (P = 0.740 and P = 0.732, respectively). The patients who died had higher levels of model for end-stage liver disease score, and higher prothrombin time than those who survived (both P < 0.001). All HVOD patients in both the survival and death groups showed ascites with abnormal imaging presentations of the liver parenchyma and hepatic blood vessels. Unexpectedly, we found that hydrothorax was detected in 21 (65.63%) patients in the death group and 19 (59.38%) patients in the survivor group during hospitalization, which was rarely mentioned in previous studies. Furthermore, international normalized ratio (INR) and creatinine are found to be potential independent prognostic factors for predicting death. Six severe patients achieved clinical improvements and survived after liver transplantation.@*CONCLUSION@#HVOD can be induced by the ingestion of G. segetum, and INR combined with creatinine has prognostic value for predicting death. Liver transplantation may be an effective treatment option for severe HVOD patients.

ABSTRACT

Objective To evaluate the efficacy of transjugular intrahepatic portosystemic shunt (TIPS)in the treatment of patients with hepatic sinusoidal obstruction syndrome (HSOS).Methods From April 2015 to August 2018,at The First Affiliated Hospital of University of Science and Technology of China,21 patients with gynura segetum caused HSOS were selected.All the patients received TIPS treatment because of unresponsiveness to anticoagulant therapy for at least two weeks.After operation patients were followed up with liver and portal vein Doppler ultrasonography examination,liver and kidney function tests,and survival observation.T test,logistic univariate regression analysis and Cox regression analysis were performed for statistical analysis.Results Among the 21 patients with gynura segetum-related HSOS,18 patients were in the subacute phase and three patients in the chronic phase.All of them were moderate or severe patients and all successfully underwent TIPS.The postoperative portal vein pressure was (16.71 ± 4.68) cmH2O (1 cmH2O =0.098 kPa),which was lower than that before operation ((41.52 ±6.27) cmH2O),and the difference was statistically significant (t =16.936,P < 0.01).The postoperation portal vein blood flow velocity was (41.52 ±7.70) cm/s,which was higher than before operation ((11.19 ± 3.29) cm/s),and the difference was statistically significant (t =-15.191,P <0.01).At one month after operation,15 of 21 patients were clinically cured;among the remaining six patients,four patients were improved and two patients were ineffective (including one patient died).At four months after operation,two patients died,and the remaining 19 patients were clinically cured.At one month after operation,the levels of alanine aminotransferase (ALT),aspartate aminotransferase (AST),total bilirubin (TBil) and serum creatinine were (23.7 ± 16.8) U/L,(33.9 ±7.4) U/L,(52.7 ± 38.2) μmol/L and (62.7 ± 12.6) μmol/L,respectively,which were lower than those before operation ((60.5 ± 42.4) U/L,(78.4 ± 42.4) U/L,(74.9 ± 38.2) μmol/L and (82.4 ± 19.6) μmol/L,respectively),and the differences were statistically significant (t =3.193,3.493,2.378 and 4.519;all P < 0.05).The level of albumin was (39.0 ±3.1) g/L,which was higher than that before operation ((30.9 ± 3.8) g/L),and the difference was statistically significant (t =-10.283,P < 0.01).Portal vein thrombosis and preoperative TBil level had predictive value for therapeutic efficacy (both P <0.05).The one-year cumulative survival rate of patients was 90.5%.Preoperative TBil level and hepatic encephalopathy had effects on the prognosis of patients (both P < 0.05).Conclusion TIPS is a safe,reliable and effective treatment for patients with subacute and chronic gynura segetum-related HSOS who are not responding to ineffective anticoagulant therapy,which can improve the prognosis and survival rate of the patients.
