Abstract

Background and Aims

Alcoholic liver disease (ALD) and non-alcoholic fatty liver disease (NAFLD) are common and increasing in prevalence. We examined prevalence and predictors of functional impairment in biopsy-proven ALD and NAFLD. Change in function over 3 years was explored.

Methods

Validated functional, cognitive, autonomic, and fatigue symptom assessment tools were completed by patients who had attended our liver clinic.

Results

Totals of 224 NAFLD and 107 ALD patients returned the assessment tools. NAFLD and ALD demonstrated comparable functional difficulties, which were significantly worse than controls (p < 0.001) with the proportion of participants experiencing difficulty significantly higher [x 2 8.93(3), (p = 0.01)]. No significant functional difficulty was demonstrated between those participants who were pre-cirrhotic or cirrhotic. Independent associations were present between difficulty with function in ALD and higher burden of autonomic and cognitive symptoms (p = 0.02) and in NAFLD-increased cognitive difficulty (p < 0.0001), age (p = 0.001), fatigue (p = 0.01), lower albumin (p = 0.02), and bilirubin (p = 0.04). PHAQ scores increased 21 % 2008–2011 {(3.2/15.6) [15.6 (0–93.8)] to 18.75 (0–90.6)}. Functional difficulty of participants alive [15.6 (0–96.9)] was significantly less compared to those who died [40.6 (0–100)] (p = 0.02).

Conclusions

NAFLD and ALD patients experience significant functional impairment affecting activities of daily living that persists over time. This has implications for the management of liver disease and service provision.
