Subclinical hepatic encephalopathy impairs daily functioning

Area of Science:

• Hepatology
• Neurology
• Psychiatry

Background:

• Subclinical hepatic encephalopathy (SHE) is presumed to affect daily functioning in cirrhosis patients, yet clinical relevance remains unquantified.
• Previous research has not established the real-world impact of SHE on patients' lives.

Purpose of the Study:

• To determine the prevalence of SHE in outpatients with cirrhosis.
• To assess the influence of SHE on patients' daily functioning using the Sickness Impact Profile (SIP) questionnaire.

Main Methods:

• 179 outpatients with cirrhosis were evaluated for SHE using psychometric tests (NCT-A, DGT) and EEG analysis.
• SHE was diagnosed based on abnormal psychometric tests or EEG slowing.
• Patient-reported daily functioning was measured using the SIP, with reproducibility assessed over 3 months.

Main Results:

• The prevalence of SHE was determined in the study cohort.
• Cirrhosis patients with SHE reported significantly greater impairment across all SIP scales (physical, psychosocial, total) compared to those without SHE.
• Multivariate analysis confirmed SHE as an independent predictor of diminished daily functioning, even after accounting for disease severity and other factors.

Conclusions:

• Subclinical hepatic encephalopathy is associated with significant impairment in daily functioning for patients with cirrhosis.
• The findings underscore the clinical relevance of SHE and support the initiation of treatment strategies.
• The SIP demonstrated high reproducibility, validating its use for assessing functional status in this population.
