OBJECTIVE: Impaired water excretion is a major prognostic factor in decompensated cirrhotic patients. We investigated if terlipressin improves water excretion after a water load test in nonazotemic cirrhotic patients with ascites without hyponatremia. METHODS: Fifteen patients (Child-Pugh B/C: 6/9) were studied after an oral water intake of 20 ml/kg within 40 min and water excretion over 5 h was measured at baseline: day 1, and after a bolus infusion (2 mg) of terlipressin: day 3. Mean arterial pressure (MAP) before and after water loading on day 1, and MAP, cardiac output (CO), and systemic vascular resistance (SVR) before and 1 h after terlipressin infusion on day 3, were evaluated. The 5-h creatinine clearance (ClCre), diuresis, and sodium excretion were also evaluated in each study day. RESULTS: The water load excreted on day 1 was significantly correlated with Child-Pugh score, ClCre, sodium excretion, and SVR. The water load excreted and diuresis increased significantly after terlipressin infusion in the 12 patients that completed the study (48.3+/-3.3% vs. 39.5+/-4.9%; p=0.001 and 2.51+/-0.21 vs. 2.06+/-0.29 ml/min; p=0.001, respectively); significant increases in ClCre and sodium excretion, a significant decrease in CO and significant increases in MAP and SVR were also noted. The changes in the percentage of water load excreted were significantly correlated with the changes in SVR and ClCre. CONCLUSIONS: Terlipressin increases water excretion during a water load test in nonazotemic cirrhotic patients without hyponatremia, suggesting that the administration of arterial vasoconstrictors could influence the prognosis of these patients.
