Terlipressin or vasopressin plus transdermal nitroglycerin in a treatment strategy for digestive bleeding in cirrhosis : a randomized clinical trial

Between 1988 and 1990 an unblinded, randomized trial of terlipressin or vasopressin plus transdermal nitroglycerin, as part of a treatment strategy including emergency sclerotherapy for actively bleeding varices, was conducted during 165 admissions in 137 patients with cirrhosis and upper digestive bleeding. Eighty-four patient admissions were assigned to terlipressin (2 mg every 6 h) and 81 to vasopressin (0.4 to 0.8 unit per min) plus transdermal nitroglycerin (20 to 80 mg). The two groups were comparable for relevant clinical data, but there were slightly more patients with hepatocellular carcinoma or terminal conditions in the terlipressin group. After the 24-h study period, failure to control bleeding was 20/84 (25%) in the vasopressin and 14/81 (17%) in the terlipressin group (p = 0.19). Corresponding figures for patients bleeding from varices (emergency sclerotherapy in 43 and 45, respectively) were 13/55 (24%) and 5/56 (9%; p = 0.035), from other sources 5/16 (31%) and 2/15 (13%; p = 0.23), from undefined sources 2/10 (20%) and 7/13 (54%; p = 0.1). In a logistic multivariate regression model the odds ratio for terlipressin adjusted for prognostic factors was 0.45 (p = 0.07). There were seven major side effects requiring treatment discontinuation in the vasopressin and one in the terlipressin group. These results suggest that terlipressin alone is as effective as vasopressin plus transdermal nitroglycerin, with less severe side effects, in 24-h control of upper gastrointestinal bleeding in patients with cirrhosis.

Which patients with cirrhosis should undergo endoscopic screening for esophageal varices (EV) detection

Our aims were to develop a noninvasive predictive tool to identify cirrhotic patients with esophageal varices and to evaluate whether portal Doppler ultrasonographic parameters may improve the value of other predictors. One hundred forty-three consecutive compensated cirrhotic patients underwent upper gastrointestinal endoscopy. Fourteen clinical, biochemical, ultrasonographic, and Doppler ultrasonographic parameters of each patient were also recorded. Esophageal varices were detected in 63 of the 143 patients examined (44%; 95% confidence interval [CI] 36.2-52.6). Medium and large esophageal varices were observed in 28 subjects (44%; 95% CI 31.4-58.4). Using stepwise logistic regression, presence of esophageal varices was independently predicted by prothrombin activity less than 70% (odds ratio [OR]: 5.83; 95% CI: 2.6-12.8), ultrasonographic portal vein diameter greater than 13 mm (OR: 2.92; 95% CI: 1.3-6.4), and platelet count less than 100 3 109/L (OR: 2.83; 95% CI: 1.27-6.28). Variables included in the model were used to generate a simple incremental rule to evaluate each individual patient. The discriminating ability of the prediction rule was relevant (area under the curve: 0.80) and did not change by replacing ultrasonographic portal vein diameter with congestion index of portal vein. We concluded that compensated cirrhotic patients should be screened by upper gastrointestinal endoscopy when prothrombin activity less than 70%, platelet count less than 100 3 109/L, and ultrasonographic portal vein diameter greater than13 mm are observed, whereas those without any of these predictors should not undergo endoscopy. The contribution provided by portal Doppler ultrasonographic parameters does not appear of practical utility. (HEPATOLOGY 2001;33:333-338.)
