To evaluate the therapeutic effect of glypressin (triglycyl-lysine-vasopressin, C52H74N16O15S2.2C2H4O2.5H2O) in the treatment of oesophageal variceal bleeding, a randomized controlled trial of glypressin and vasopressin was conducted in 54 cirrhotic patients with oesophageal varices bleeding. Bleeding ceased within 24 h in 50% (13/26) of patients treated with glypressin and in 53.6% (15/28) of patients given vasopressin. Re-bleeding within 7 days occurred in 30.8% (4/13) of the glypressin group and in 20.0% (3/15) of the vasopressin group. There was no statistically significant difference in the therapeutic effect between glypressin and vasopressin. In the glypressin group, bleeding was more easily stopped in non-hepatocellular carcinoma (HCC) cirrhotic patients of Pugh's criteria A or B than in patients of Pugh's criterion C or HCC. We conclude that glypressin and vasopressin have similar therapeutic effect. In considering the application convenience, glypressin is an alternative to vasopressin in the treatment of bleeding varices in patients of good liver function reserve.

Somatostatin (ST) and vasopressin (VP) infusions were compared in the treatment of actively bleeding esophageal varices. Fifty-four patients with liver cirrhosis were included in the study. Thirty-two were given ST 4.2 micrograms/min, and 22 patients were given VP 0.4 IU/min for 72 h after endoscopic diagnosis. The role of alcoholic cirrhosis was similar in both groups. Initial control of bleeding was achieved significantly more often (p = 0.0281) when ST was used (84.4%) than during VP treatment (57.1%). Rebleeding occurred in 18.8% and 4.8%, respectively. Side effects of treatment were significantly more common when VP was used than during ST treatment (p = 0.0021). Overall mortality was high in both groups, being 34% in the ST group and 36% in the VP group. ST infusion seems to be more effective and safer than VP in the treatment of acute variceal bleeding. However, the high frequency of rebleeding during ST treatment means that, after primary hemostasis with ST infusion, other methods, such as surgery or sclerotherapy, are needed to prevent the serious complications of rebleeding.

We report a 33-year-old man who developed cutaneous necrosis of the lower extremities with extensive bulla formation after i.v. administration of vasopressin for the treatment of bleeding esophageal varices. Due to its potent nonselective vasoconstrictive action, vasopressin not only may induce cardiac and gastrointestinal ischemia, but cutaneous ischemia as well. As in our patient, this may lead to extensive necrotic skin lesions at sites distant from the infusion.

A continuous IV infusion of vasopressin was administrated to a patient with cirrhosis of the liver and acute gastrointestinal bleeding from esophageal varices. In the first 24 hours, the patient developed rhabdomyolysis and cutaneous necrosis. Stopping vasopressin infusion resulted in relief of these lesions. The rarity of these complications suggests an idiosyncratic reaction of susceptible individuals that may be related to previous vascular disease or a failure in baroreceptor regulation.

Vasopressin infusion and esophageal tamponade are still widely used to arrest variceal bleeding, but no objective evidence exists on the superiority of either of the two procedures. In this study, 108 cirrhotic patients bleeding from varices were included in a prospective, randomized trial to investigate the comparative effectiveness and safety of balloon tamponade (using the Sengstaken-Blakemore tube for esophageal varices and the Linton-Nachlas tube for gastric varices) (n = 52) and intravenous vasopressin infusion (0.4 to 0.8 mu/min) plus intravenous nitroglycerin infusion (40 to 400 micrograms/min) (n = 56). Both treatments were maintained for 24-hr. The hemostatic efficacy according to the intention to treat was 86.5% for tamponade and 66% for pharmacological therapy (p less than 0.01). No significant differences were found with respect to rebleeding during the first 72 hr after treatment, mortality rate or side effects. These results suggest that esophageal tamponade is more effective than vasopressin/nitroglycerin infusion in the treatment of variceal bleeding in cirrhotic patients.

To assess vasopressin control of esophageal variceal bleeding, we investigated the effect of vasopressin on the left gastric venous flow, portal venous flow, superior mesenteric venous flow, and splenic venous flow in seven cirrhotic patients with esophageal varices, using a duplex system consisting of a real-time ultrasonograph and an echo-Doppler flowmeter. Infusion of vasopressin (0.3 U/min) significantly decreased the blood flow in the left gastric vein (-56%), portal trunk (-54%), superior mesenteric vein (-54%), and splenic vein (-56%) as a result of decrease of blood velocity in these vessels. Thus, vasopressin seems to control esophageal variceal bleeding, in part, by reducing blood velocity and blood flow in the left gastric vein following reduction of blood velocity and blood flow in the superior mesenteric vein and splenic vein.

The haemostatic effect of terlipressin (triglycyl-lysine vasopressin; Glypressin) on bleeding from oesophageal varices was evaluated in a placebo-controlled, double-blind, randomized clinical trial. Patients with clinically suspected liver cirrhosis were included in the study if they had been admitted to hospital with an extensive haemorrhage within the last 24h before diagnostic endoscopy. The patients randomized after stratification for severity of liver disease. Terlipressin or placebo was administered as intravenous bolus injections every 4th h during a period of 24 to 36 h or until the clinical course necessitated active intervention (failure or withdrawal). Sixty patients entered the study; 31 patients were allocated to receive terlipressin, and 29 patients to receive placebo. Bleeding from varices was arrested in 28 of the 31 receiving terlipressin, as compared with 17 of the 29 receiving placebo (p less than 0.01). Patients receiving active drug required significantly fewer blood transfusions (p less than 0.05). Most of the side effects were classified as mild and were registered in the terlipressin group.

Patients with cirrhosis and esophagogastric varices have a 25% to 33% risk of initial variceal bleeding, a risk of up to 70% for recurrent variceal bleeding, and an associated mortality of up to 50%. Based on a review of prospective randomized trials, control of acute variceal bleeding should involve vasopressin plus nitroglycerin as indicated for minor bleeding episodes, sclerotherapy for more severe bleeding episodes, and staple transection of the esophagus for patients who do not respond to these initial measures. Emergency portasystemic shunt surgery cannot be recommended at this time. For prevention of recurrent variceal hemorrhage, the data support the use of nonselective beta-adrenergic blockers (propranolol or nadolol) for patients with good liver function (Child's class A and B) and the use of chronic sclerotherapy to obliterate esophageal varices for patients with decompensated cirrhosis (Child's class C). Surgical procedures should be reserved for failures of medical management. The use of beta-adrenergic blockers offers the most promise for prevention of initial variceal bleeding.

Although controversial, pharmacological therapy aimed at controlling acute variceal bleeding is widely used. A combination of intravenous vasopressin and nitroglycerin or glypressin alone with the aim of lowering portal pressure is currently recommended. Immediate endoscopy is mandatory to confirm that the patient is bleeding from varices. When variceal bleeding is detected, the patient should be immediately submitted to sclerotherapy, if expert treatment is available, or have the bleeding controlled by balloon tamponade or by pharmacological means, with subsequent performance of sclerotherapy with the use of a flexible endoscope within 6 to 24 hours, or transportation of the patient to a special center during this time. If bleeding has stopped, sclerotherapy can be performed immediately, or the patient can be observed while appropriate long-term management is planned. Patients who do not respond to immediate or delayed emergency sclerotherapy should be identified early and their suitability for a shunt or devascularisation procedure assessed. There is no question that at least after one or two early or even late recurrences of variceal hemorrhage, surgery should be planned and initiated. Although sclerotherapy is the favored form of emergency treatment, a nonshunting procedure or a portosystemic shunt operation should be recommended and thoroughly evaluated in order to determine whether this may be a preferable therapeutic option in a minority of patients, representing about 20% of all patients bleeding from esophageal varices referred to our institution.

Bleeding from esophageal varices is related to the size and pressure of varices, endoscopic danger signs, and severity of liver failure. Prevention of bleeding with propranolol has given conflicting results in controlled trials, but is a safe treatment. Prophylactic sclerotherapy has been shown to reduce bleeding in European studies, but this has not been confirmed by studies in the United States. Acute variceal bleeding can usually be controlled by sclerotherapy, which may be supplemented by pharmacotherapy with vasopressin, nitroglycerin, or somatostatin. Recurrent bleeding is prevented initially by sclerotherapy, with surgery reserved for patients who have not responded to this treatment. Once bleeding has been controlled, the suitability and timing of hepatic transplantation must be considered.
