AIM: Pyrrolizidine alkaloids-induced hepatic sinusoidal obstruction syndrome(PA-HSOS) has been reported to have high mortality. We evaluated the efficacy and safety of anticoagulation therapy for the patients with PA-HSOS.
METHODS: We collected clinical data on 249 PA-HSOS patients from January 2012 to December 2017 at four tertiary care hospitals. Among them, 151 patients received anticoagulation therapy, and 98 patients received supportive treatment. The outcomes were analyzed using the Fine and Gray competing risk analysis method and Cox regression model.
RESULTS: The cumulative complete response rate was higher in the anticoagulation group than in the supportive group (60.9 vs 36.7%; P < 0.0001). The cumulative mortality was 12.6% in the anticoagulation group compared with 43.9% in the supportive group (P < 0.0001). In subgroup analysis, for mild, moderate, severe, and very severe groups, the adjusted hazard ratios [95% confidence interval (CI)] for complete response rates were 7.05 (3.00-16.59), 5.26 (2.31-12.42), 2.59 (0.85-7.87), and 2.05 (0.61-6.92), respectively; and the adjusted hazard ratios (95% CI) for mortalities were 0.02 (0.01-0.09), 0.04 (0.01-0.14), 0.19 (0.01-3.98), and 0.07 (0.02-1.27), respectively (P < 0.0001). There was no significant difference between both groups in the incidence of bleeding events (P = 0.674).
CONCLUSIONS: Anticoagulation therapy improves clinical remission and the survival in selected patients with mild or moderate PA-HSOS. Anticoagulation therapy has a similar safety profile to supportive therapy.
