This systematic review examined hepatic encephalopathy (HE) characteristics, treatment strategies and outcomes in adults with alcohol-related cirrhosis or documented alcohol consumption. It included 14 randomized trials and cohort studies, with 6,185 participants; heterogeneity required narrative synthesis. Hospital prevalence of HE was 18.5%, and 90-day mortality was 12.1%. Observational evidence linked HE with higher mortality (HR 3.1 at 90 days; HR 2.9 at 1 year). Rifaximin was associated with less recurrence in secondary prophylaxis (HR 0.42), usually alongside lactulose. The authors judged the evidence indirect and heterogeneous, insufficient to establish a distinct alcohol-related HE phenotype.
Key findings
- Across included studies, hospital prevalence of HE was 18.5%, and 90-day mortality was 12.1%.
- Observational evidence associated HE with higher mortality: HR 3.1 at 90 days and HR 2.9 at 1 year.
- Rifaximin was associated with reduced recurrence in secondary prophylaxis (HR 0.42), predominantly as add-on therapy to lactulose.
- Active alcohol consumption was identified as a potential adverse prognostic factor (HR 2.5); polyethylene glycol showed faster improvement than lactulose in acute HE, with limited evidence.
Why it matters
The review highlights substantial morbidity and mortality associated with HE in alcohol-related cirrhosis and summarizes treatment findings relevant to recurrence and acute episodes. However, much of the evidence comes from mixed-etiology populations, so these estimates may not define outcomes or treatment effects specific to alcohol-related disease. The findings underscore the need for evidence that directly characterizes this population.
What to keep in mind
Substantial heterogeneity required narrative synthesis, and evidence was largely indirect from mixed-etiology populations, limiting conclusions about a distinct alcohol-related HE phenotype.
