Impact of Treatment Response to Anticoagulant Therapy on Liver-Related Events in Patients With Cirrhosis and Portal Vein Thrombosis
Research article published in Hepatology research : the official journal of the Japan Society of Hepatology (2026)
Abstract
AIM: The effect of treatment response to anticoagulant therapy on prognosis of patients with cirrhosis and portal vein thrombosis (PVT) remains unclear. METHODS: Forty-one patients with cirrhosis and first PVT treated with intravenous anticoagulant therapy between January 2015 and April 2018 at 10 Japanese hospitals were included. Treatment response was defined based on change in size of PVT after anticoagulant therapy as the following: complete response (CR, 0%), partial response (PR, ≤ 50%), stable disease (SD, 51%-100%), and progressive disease (PD, ≥ 101%). CR and PR were combined as the effective group and SD and PD formed as the ineffective group. RESULTS: The median age was 69 years, and 56% of the patients had Child-Pugh class B. Overall, 5 (12%) achieved CR, 22 (54%) achieved PR, 12 (29%) had SD and 2 (5%) had PD. During a median follow-up of 31.8 months from the date of assessment of treatment response, 17 patients died. The overall survival rates at 1- and 3-year were 82.5% and 65.1%, respectively. In the multivariate analysis, the model for end-stage liver disease-Na score was significantly associated with overall survival, whereas treatment response was not significant. Twenty-five patients experienced liver-related events with hospitalization, and the 3-year cumulative rate of liver-related events was 63.9%. In the multivariate analysis, treatment response was significantly associated with liver-related events. The 3-year cumulative rates of liver-related events were 56.7% and 75.5% in the effective and ineffective groups, respectively (p = 0.008). CONCLUSIONS: Among patients with cirrhosis, treatment response to anticoagulant therapy for PVT correlated with the incidence of liver-related hospitalization events.

Resumen
The effect of treatment response to anticoagulant therapy on prognosis of patients with cirrhosis and portal vein thrombosis (PVT) remains unclear. Forty-one patients with cirrhosis and first PVT treated with intravenous anticoagulant therapy between January 2015 and April 2018 at 10 Japanese hospitals were included.
Por qué esto importa para la hirudoterapia
Este estudio multicéntrico japonés de 41 pacientes con cirrosis y una trombosis portal primaria tratados con anticoagulación intravenosa evaluó la respuesta al tratamiento según el cambio en el tamaño del trombo y halló que, si bien la respuesta no predijo significativamente la supervivencia global (determinada en su lugar por la puntuación MELD-Na), una respuesta anticoagulante eficaz estuvo significativamente asociada con menos eventos de hospitalización relacionados con el hígado (tasa acumulada de 3 años del 56,7% en respondedores frente al 75,5% en no respondedores, P = 0,008). Es relevante para el panorama de la evidencia clínica de la hirudoterapia como una visión realista de cómo la disolución exitosa del trombo venoso se traduce en resultados significativos para el paciente en una población cirrótica frágil y propensa a hemorragias, el tipo de equilibrio riesgo-beneficio que cualquier estrategia antitrombótica debe respetar. Las limitaciones son que este es un pequeño cohorte observacional (41 pacientes en 10 hospitales) de anticoagulación intravenosa convencional, no hirudoterapia, y el análisis de supervivencia tenía poco poder estadístico, por lo que la asociación con eventos relacionados con el hígado es generadora de hipótesis en lugar de confirmatoria.
