Hemodynamic effects of acute administration of furosemide in patients with cirrhosis receiving beta-adrenergic antagonists.

In patients with cirrhosis, both beta-blockers and diuretics decrease the degree of portal hypertension. Since their mechanisms of action differ, the combination of these two substances should induce a more pronounced effect on portal pressure than one of these substances alone. Thus, the hemodynamic effects of furosemide were evaluated in ten patients with cirrhosis receiving beta-blockers. One hour after furosemide (0.75 mg/kg intravenously) administration, cardiac output decreased significantly from 6.2 +/- 0.6 to 5.2 +/- 0.3 l/min and blood volume from 8.0 +/- 1.6 to 5.3 +/- 0.5 l. Mean arterial pressure was not affected. Wedged and free hepatic venous pressures did not change significantly; nor did the hepatic venous pressure gradient (19.6 +/- 1.7 to 18.6 +/- 1.5 mmHg). Azygos blood flow was not affected (0.46 +/- 0.05 to 0.50 +/- 0.07 l/min). In conclusion, this study did not demonstrate that the addition of furosemide to propranolol further decreased portal pressure in patients with cirrhosis. The long-term effects of this combination are unknown and should be tested.Journal ArticleResearch Support, Non-U.S. Gov'tinfo:eu-repo/semantics/publishe

Relationship between portal pressure, esophageal varices, and variceal bleeding on the basis of the stage and cause of cirrhosis.

Hepatic venous pressure gradient, esophageal varices, and variceal bleeding were investigated in 957 patients with cirrhosis. The causes (alcoholic/virus) and stage (Child-Pugh's classification) of cirrhosis were also taken into account.Comparative StudyJournal Articleinfo:eu-repo/semantics/publishe

Acute effects of propylthiouracil on hemodynamics and oxygen content in patients with alcoholic cirrhosis.

The antithyroid drug propylthiouracil has been suggested for the treatment of alcoholic liver disease. Its beneficial effects could be due to either a decrease in hepatic oxygen consumption or an increase in hepatic blood flow. The aim of this study was to test these two hypotheses in patients with proven alcoholic cirrhosis.Journal ArticleResearch Support, Non-U.S. Gov'tinfo:eu-repo/semantics/publishe

Plasma endotoxin and tumor necrosis factor-alpha in the hyperkinetic state of cirrhosis.

BACKGROUND/AIMS: The factors which trigger the hyperdynamic circulation in cirrhosis remain poorly defined. Plasma levels of the potent vasodilators endotoxin and tumor necrosis factor-alpha may be elevated in patients with cirrhosis, and therefore the potential role of these substance was assessed in the hyperkinetic circulation in cirrhosis. METHODS: Forty-nine patients in stable condition underwent systemic and hepatic hemodynamic measurements, and right atrial blood sampling for endotoxin and tumor necrosis factor-alpha assays. Patients were divided into three groups according to the severity of the disease: group 1 consisted of eight patients with normal liver or mild hepatic fibrosis, and groups 2 and 3 contained 17 and 24 patients with Child A and Child B or C cirrhosis, respectively. RESULTS: Systemic vascular resistance decreased and cardiac index increased from group 1 to 3: 1530 +/- 196 dyn.s.cm-5 to 990 +/- 72 dyn.s.cm-5 (mean +/- S.E. p<0.05) and 3.1 +/- 0.3 l.min-1.m-2 to 4.2 +/- 0.2 l.min-2.m-2, respectively. Endotoxin was not detectable in any of the groups and tumor necrosis factor-alpha was increased in one patient from group 1, six from group 2 and six from group 3. Mean tumor necrosis factor-alpha levels were not different among the groups (10 +/- 5, 18 +/- 5 and 17 +/- 7 pg/ml in groups 1, 2 and 3, respectively). Systemic vascular resistance and cardiac index were not correlated to plasma tumor necrosis factor-alpha levels; patients with increased levels of this cytokine did not have worse hyperdynamic circulation in any of the groups. CONCLUSIONS: These results suggest that tumor necrosis factor-alpha and endotoxin do not play a role in the maintenance of the hyperkinetic state of cirrhosis.Journal ArticleSCOPUS: ar.jinfo:eu-repo/semantics/publishe
