The hemoglobin threshold for transfusion of red cells in patients with acute gastrointestinal bleeding is controversial. We compared the efficacy and safety of a restrictive transfusion strategy with those of a liberal transfusion strategy.

In compensated cirrhosis, a threshold value of hepatic venous pressure gradient (HVPG) ≥10 mm Hg is required for the development of decompensation. However, whether the treatment of portal hypertension (PHT) can prevent the transition into development of ascites once this level has been reached is unclear. Our aim was to assess the relationship between changes in HVPG induced by β-blockers and development of ascites in compensated cirrhosis with severe PHT. Eighty-three patients without any previous decompensation of cirrhosis, with large esophageal varices and HVPG ≥12 mm Hg were included. After baseline hemodynamic measurements nadolol was administered and a second hemodynamic study was repeated 1-3 months later. During 53±30 months of follow-up, decompensation occurred in 52 patients (62%) and in 81% of them ascites was the first manifestation. Using receiver operating characteristic curve analysis a decrease in HVPG ≥10% was the best cutoff to predict ascites. As compared with nonresponders, patients with an HVPG decrease ≥10% had a lower probability of developing ascites (19% vs. 57% at 3 years, P<0.001), refractory ascites (P=0.007), and hepatorenal syndrome (P=0.027). By Cox regression analysis hemodynamic nonresponse was the best predictor of ascites. By stepwise logistic regression, development of ascites was independently associated with nonresponse, whereas refractory ascites, hepatorenal syndrome, and spontaneous bacterial peritonitis were not. In patients with compensated cirrhosis and large varices treated with β-blockers, an HVPG decrease ≥10% significantly reduces the risk of developing ascitic decompensation and other related complications such as refractory ascites or hepatorenal syndrome.

Falls are frequent among patients with debilitating disorders and can have a serious effect on health status. Mild cognitive disturbances associated with cirrhosis may increase the risk for falls. Identifying subjects at risk may allow the implementation of preventive measures. Our aim was to assess the predictive value of the Psychometric Hepatic Encephalopathy Score (PHES) in identifying patients likely to sustain falls. One hundred and twenty-two outpatients with cirrhosis were assessed using the PHES and were followed at specified intervals. One third of them exhibited cognitive dysfunction (CD) according to the PHES (<−4). Seventeen of the forty-two patients (40.4%) with CD had at least one fall during follow-up. In comparison, only 5 of 80 (6.2%) without CD had falls ( P < 0.001). Fractures occurred in 4 patients (9.5%) with CD, but in no patients without CD ( P = 0.01). Patients with CD needed more healthcare (23.8% versus 2.5%; P < 0.001), more emergency room care (14.2% versus 2.5%; P = 0.02), and more hospitalization (9.5% versus 0%; P = 0.01) as a result of falls than patients without CD. Patients taking psychoactive treatment (n = 21) had a higher frequency of falls, and this was related to an abnormal PHES. In patients without psychoactive treatment (n = 101), the incidence of falls was 32.4% in patients with CD versus 7.5% in those without CD ( P = 0.003). In the multivariate analysis, CD was the only independent predictive factor of falls (odds ratio, 10.2; 95% confidence interval, 3.4–30.4; P < 0.001). The 1-year probability of falling was 52.3% in patients with CD and 6.5% in those without ( P < 0.001). Conclusion: An abnormal PHES identifies patients with cirrhosis who are at risk for falls. This psychometric test may be useful to promote awareness of falls and identify patients who may benefit from preventive strategies.
