Abstract
Background: Terlipressin or octreotide given alone has been used as the first-line pharmacological treatment for acute variceal bleeding. In portal hypertensive animals, pre-infusion of octreotide followed by the addition of terlipressin has an additive or complementary effect on splanchnic hemodynamics. The current study was aimed at evaluating such a combination treatment in patients with cirrhosis and portal hypertension. Methods: Patients were randomly assigned to receive either a placebo ( n = 11) or an intravenous infusion of octreotide 100 μg/h after an initial bolus of 100 μg ( n = 13). Thereafter, each patient received an intravenous injection of terlipressin 2 mg. Hemodynamic values were measured basally, 30 min after octreotide or placebo, and 60 min after terlipressin. Results: Placebo administration did not affect any of the hemodynamic values. Terlipressin administration resulted in expected changes in hepatic venous pressure gradient, hepatic blood flow and systemic hemodynamics. In contrast, octreotide administration significantly decreased hepatic blood flow but did not affect other hemodynamic values. After terlipressin administration, significant hemodynamic changes were observed that were similar to the hemodynamic changes with terlipressin alone. The magnitude of changes in hepatic venous pressure gradient, cardiac index and systemic vascular resistance were no different between the two groups of patients. The heart rate was significantly lower in patients receiving octreotide plus terlipressin than those receiving terlipressin alone. Conclusion: The current study showed that a combination of octreotide and terlipressin did not exert an additive effect in reducing hepatic venous pressure gradient in patients with cirrhosis. In addition, the systemic hemodynamic changes were comparable between the two groups.
