Background
Decompensated liver cirrhosis patients with refractory ascites or pleural effusion have a poor prognosis. Tolvaptan has been used for treating water retention associated with cirrhosis. However, despite the short-term response, water retention recurrence is still observed in some cases. This study aimed to clarify the water retention recurrence rate and the relationship between long-term response without recurrence and prognosis.
Methods
Altogether, 100 patients with decompensated cirrhosis treated with tolvaptan were retrospectively analyzed. Recurrence was evaluated according to the criteria of the EASL clinical practice guideline. The recurrence rate and prognosis of non-responders, patients with recurrence, and long-term responders were analyzed. The baseline factors related to short-term response, recurrence, and long-term response were also evaluated.
Results
Approximately 31.0% of the short-term responders had recurrence. Although there was no significant difference in the prognosis by short-term response (p = 0.07), the long-term responders had a significantly better prognosis than those with recurrence and non-responders (p < 0.01). Low CRP levels and high urinary Na/K ratios were significant factors related to short-term response, and the presence of acute kidney injury was also a factor related to non-response. The low CRP level (relapse: < 1.10 mg/dl, long-term response: < 0.94 mg/dl) was identified as a factor related to recurrence and long-term response.
Conclusion
The long-term responders without recurrence had a significantly better prognosis. CRP was a useful predictor for long-term response, whereas renal function parameters were useful predictors for short-term response. Inflammation control may be important for long-term response and prognosis in cirrhosis patients with water retention.
