Primary prophylaxis of variceal bleeding in cirrhotic patients: A cohort study

BACKGROUND Current guidelines recommend beta-blockers for primary prevention of variceal haemorrhage in cirrhotic patients, and band ligation for patients with contraindications or intolerance to beta-blockers. However, it has been suggested that these patients may respond poorly to band ligation. AIM We evaluated the usefulness of a strategy in which band ligation was used to treat patients with contraindications or intolerance and patients not responding to beta-blockers identified by hepatic vein pressure gradient measurement. Haemodynamic responders and patients refusing hepatic vein pressure gradient measurement were given long-term beta-blockers. METHODS One hundred and thirty-five consecutive patients with high-risk oesophageal varices and no prior bleeding were enrolled. Twenty-five patients with contraindications (group A), 26 with intolerance to beta-blockers (group B) and 25 showing a poor haemodynamic response (Group C) underwent band ligation. Twenty-two haemodynamic responders (Group D) and 37 refusing hepatic vein pressure gradient measurement (Group E) were treated with beta-blockers. RESULTS Median follow-up was 32 months. 12/135 patients (8.9%) bled: 3/25 (12%) in group A, 1/26 (3.8%) in group B, 0/25 (0%) in group C, 0/22 (0%) in group D and 8/37 (22.2%) in group E. Mortality was 8/135 (5.9%). CONCLUSIONS Patients with contraindications, intolerance or not responding to beta-blockers treated with band ligation achieve protection from variceal bleeding comparable to that of good responders to beta-blockers.

High-d-dimer plasma levels predict poor outcome in esophageal variceal bleeding

BACKGROUND AND AIM Variceal bleeding carries a high-mortality rate in patients with liver cirrhosis. Since coagulation and fibrinolysis are abnormal in these patients we evaluated whether or not abnormalities of these haemostasis systems were independently related to mortality. METHODS Global coagulation, coagulation activation and fibrinolysis measurements were performed in 43 cirrhotics bleeding from esophageal varices at baseline and during follow-up and in 43 non-bleeding cirrhotic patients at baseline only. RESULTS Baseline measurements of coagulation activation and fibrinolysis were more impaired in bleeders. In bleeders, prothrombin time, tissue type plasminogen activator antigen and D-dimer plasma levels were persistently more abnormal in patients who died. High-D-dimer, infection, Child-Pugh C class and MELD score >or=17 were the significant predictors of death at univariate analysis. Two different multivariate analyses to assess the independent prognostic value of these variables, one including the Child-Pugh class, the other including MELD, were performed. Independent predictors of death were high-D-dimer and infection, but not Child-Pugh class, in the former; MELD and infection, but not D-dimer, in the latter. CONCLUSIONS Beside infection, high-D-dimer is a stronger predictor of death as compared to Child-Pugh C class, but not to a MELD score >or=17.
