BACKGROUND: Anticoagulation therapy (AT) is often used as the initial treatment for pyrrolizidine alkaloid (PA)-induced hepatic sinusoidal obstruction syndrome (HSOS). However, transjugular intrahepatic portosystemic shunt (TIPS) is an alternative treatment. This study aimed to determine the mid- to long-term outcomes of TIPS versus AT as the initial treatment for PA-induced HSOS.
METHODS: We retrospectively analyzed the clinical data of 61 patients with PA-induced HSOS that were collected between November 2015 and July 2021. The patients were allocated to the TIPS group ( n = 20) or the AT group ( n = 41). These two groups were divided into subgroups according to the severity grading. The clinical data of the patients in both groups were analyzed. Cumulative survival rates were calculated and compared between the two groups and among the subgroups.
RESULTS: The clinical symptoms and signs improved or stabilized in 100% of the patients following TIPS and in 85% of the patients following AT at discharge ( P = 0.166). The mortality rate was 0.0% in the TIPS group and 34.1% in the AT group ( P = 0.005). The patients were followed up for 2-69 months (mean, 26.3 ± 20.5 months). In the mild- and moderate-grade subgroups, there was no difference in the cumulative survival rate between the TIPS and AT groups ( P = 0.589 and P = 0.364, respectively). In the severe and very severe-grade subgroups, the cumulative survival rate was higher in the TIPS group than in the AT group ( P = 0.018 and P = 0.025, respectively).
CONCLUSION: AT is a suitable initial treatment for mild or moderate PA-induced HSOS, whereas TIPS should be considered the appropriate initial treatment for severe or very severe PA-induced HSOS.
