title: Hemodynamic effects of terlipressin and high somatostatin dose during acute variceal bleeding in nonresponders to the usual somatostatin dose.
abstract: OBJECTIVE
  High dose of somatostatin infusion achieves a greater reduction of hepatic venous pressure gradient (HVPG) than the usual dose, and terlipressin decreases HVPG through mechanisms other than somatostatin. Our aim was to assess the hemodynamic effects of terlipressin and high somatostatin dose during acute variceal bleeding in nonresponders to the usual somatostatin dose.
  
  
  METHODS
  Hemodynamic studies were performed in 80 patients with cirrhosis and variceal bleeding during the first 3 days of admission. After baseline measurements, somatostatin was administered (250 microg/h with an initial bolus of 250 microg). Patients were considered responders when the HVPG decreased by >10% from baseline (n = 31). Nonresponders were randomized under double-blind conditions to a control group (n = 7), or to receive terlipressin (2 mg IV bolus, n = 22), or high dose of somatostatin (500 microg/h, n = 20). Final measurements were obtained 30 min later.
  
  
  RESULTS
  Terlipressin caused a decrease in HVPG (from 22.2 +/- 5 to 19.1 +/- 5.2, p < 0.01) and heart rate (p < 0.01), while mean arterial pressure increased (p < 0.01). High somatostatin dose also reduced HVPG (from 21.8 +/- 3.4 to 19.6 +/- 3.1, p < 0.01), although this decrease was more pronounced with terlipressin (15%+/- 9%vs 10%+/- 6% from baseline, p= 0.05). Both terlipressin and high somatostatin dose achieved a significantly higher rate of response than that in the control group. A decrease in HVPG >20% was observed in 36% of cases with terlipressin versus 5% with high somatostatin dose (p= 0.02).
  
  
  CONCLUSIONS
  In nonresponders to usual somatostatin dose, both terlipressin and high-dose of somatostatin infusion significantly decreased HVPG and increased the rate of hemodynamic responders. Such effects were greater with terlipressin. Both treatments may be an alternative when standard somatostatin fails.
