Effects of continuous use of probiotics before liver transplantation: A randomized, double-blind, placebo-controlled...

Although there is increasing evidence for the benefits of probiotics in patients with liver diseases, data on the benefits of pre-LT administration of probiotics are lacking. The aim of this study was to evaluate the effects of continuous administration of probiotics before liver transplantation (LT) on pre- and post-transplant patient outcomes.

In this randomized, double-blind, and placebo-controlled trial adult cirrhotic patients listed for LT received a 4-strain probiotic preparation or placebo daily from enrollment until LT. The primary outcome measures were postoperative mortality and infection rates. The secondary outcome measures were 5-day post-transplant aspartate and alanine aminotransferase activities, bilirubin concentration, and international normalized ratio; waiting-list mortality; pre-transplant Model for End-stage Liver Disease score and Child-Turcotte-Pugh class changes; and pre-transplant infections.

A total of 55 patients were randomized. The 90-day postoperative mortality rates were 0% and 4.3% in the probiotic and placebo groups, respectively (p > 0.99). Patients receiving probiotics had significantly reduced 30-day (4.8% versus 34.8%, p = 0.02) and 90-day (4.8% versus 47.8%, p = 0.002) infection rates, lower post-LT bilirubin concentration (p = 0.02), and more rapid decrease of aspartate (p = 0.03) and alanine (p = 0.03) aminotransferase activities. Probiotics did not have significant effects on other secondary outcome measures.

Although continuous administration of probiotics before LT does not appear to affect postoperative mortality, it effectively prevents postoperative infections and improves early biochemical parameters of allograft function. CLINICALTRIALS.
