Core Tip

Core Tip: Bacterial translocation exacerbates the hyperdynamic circulation observed in cirrhosis and contributes to a more severe disease course. Probiotics may reduce bacterial translocation and may therefore be useful to redress the circulatory imbalance. The aim of the study was to investigate the effect of probiotics on hemodynamic parameters, systemic inflammation, and complications of cirrhosis in this randomized placebo-controlled trial. Following a 3-mo course of probiotics, we observed amelioration of hyperdynamic circulation and systemic inflammation, improvement liver function, regression of ascites and hepatic encephalopathy, and an increase in serum sodium level.
