Abstract:
Objective:To explore pyrrolizidine alkaloid-induced hepatic sinusoidal obstruction syndrome (PA-HSOS) severity grading to predict the prognostic value for PA-HSOS patients treated with transjugular intrahepatic portosystemic shunt (TIPS).Methods:Clinical data of patients with PA-HSOS who were critically ill or had ineffective drug treatment and underwent TIPS treatment from December 2013 to September 2019 were retrospectively analyzed. PA-HSOS severity grading criteria in adult was quoted, revised and defined from the European Group for Blood and Marrow Transplantation (EBMT). The survival time, the rate of shunt dysfunction and the incidence of postoperative hepatic encephalopathy in different severity groups after TIPS were compared. Univariate Cox or Binomial Logistic regression analysis was used to evaluate the impact of each variable. Variables with P < 0.1 were regarded as statistically significant variables for the prognosis, and were introduced into Cox or Binomial Logistic regression hierarchical regression analysis as controlled covariates. PA-HSOS severity grading was analyzed as dummy variables.Results:A total of 102 patient data were collected, and the median follow-up time was 14.52 months. The difference in survival time of patients with different severity levels was statistically significant ( P = 0.023). The mortality risk in moderate patients was 1.575 times higher than that of mild patients (95% CI: 0.216-11.457, P = 0.654). The mortality risk of severe and very severe patients was 7.424 times higher than that of mild patients (95% CI: 1.612-34.197, P = 0.010). There was no statistically significant difference in postoperative hepatic encephalopathy recurrence rate and shunt dysfunction rate ( P > 0.05). Conclusion:PA-HSOS severity grading has prognostic value for PA-HSOS patients receiving TIPS treatment, and can be used as an important reference for guiding the timing of TIPS intervention.
