PPIs were used by 52% of this international cirrhosis cohort during a 1-year period and was a risk factor for developing HE and SBP. These findings are consistent with the hypothesis that PPIs may increase translocation of gut bacteria. (Hepatology 2016;64:1265-1272).

Branched-chain amino acids for people with hepatic encephalopathy.

No abstract

Supplements with branched-chain amino acid (BCAA) have cerebral, metabolic, and nutritional effects that may benefit patients with hepatic encephalopathy (HE). We therefore conducted a systematic review on the effects of oral BCAAs compared with control supplements or placebo for patients with cirrhosis and recurrent overt or minimal HE. The quantitative analyses included data from 8 trials (n = 382 patients). Individual patient data were retrieved from 4 trials to recalculate outcomes (n = 255 patients). The mean dose of the oral BCAA supplements was 0.25 g/(kg body weight · d). Random effects meta-analysis showed that improvements in HE manifestations were registered for 87 of 172 patients in the BCAA group compared with 56 of 210 controls [risk ratio = 1.71 (95% CI: 1.17, 2.51) number needed to treat = 5 patients]. The effect of BCAAs differed (P = 0.04) for patients with overt [risk ratio = 3.26 (95% CI: 1.47, 7.22)] and minimal HE [risk ratio = 1.32 (95% CI: 0.97, 1.79)]. Subgroup, sensitivity, regression, and sequential analyses found no other sources of heterogeneity or bias. BCAA supplements had no effect on mortality or markers of nutritional status and did not induce adverse events. In conclusion, oral BCAA supplements improve manifestations of HE but have no effect on survival.
