Abstract

Background & aims: Patients with advanced fibrosis related to nonalcoholic fatty liver disease (NAFLD) are at risk of developing hepatic and extrahepatic complications. We investigated whether, in a large cohort of patients with NAFLD and compensated advanced chronic liver disease, baseline liver stiffness measurements (LSMs) and their changes can be used to identify patients at risk for liver-related and extrahepatic events.

Methods: We performed a retrospective analysis of consecutive patients with NAFLD (n = 1039) with a histologic diagnosis of F3-F4 fibrosis and/or LSMs>10 kPa, followed for at least 6 months, from medical centers in 6 countries. LSMs were made by FibroScan using the M or XL probe and recorded at baseline and within 1 year from the last follow-up examination. Differences between follow up and baseline LSMs were categorized as: improvement (reduction of more than 20%), stable (reduction of 20% to an increase of 20%), impairment (an increase of 20% or more). We recorded hepatic events (such as liver decompensation, ascites, encephalopathy, variceal bleeding, jaundice, or hepatocellular carcinoma [HCC]) and overall and liver-related mortality during a median follow-up time of 35 months (interquartile range, 19-63 months).

Results: Based on Cox regression analysis, baseline LSM was independently associated with occurrence of hepatic decompensation (hazard ratio [HR], 1.03; 95% CI, 1.02-1.04; P < .001), HCC (HR, 1.03; 95% CI, 1.00-1.04; P = .003), and liver-related death (HR, 1.02; 95% CI, 1.02-1.03; P = .005). In 533 patients with available LSMs during the follow-up period, change in LSM was independently associated with hepatic decompensation (HR, 1.56; 95% CI, 1.05-2.51; P = .04), HCC (HR, 1.72; 95% CI, 1.01-3.02; P = .04), overall mortality (HR, 1.73; 95% CI, 1.11-2.69; P = .01), and liver-related mortality (HR, 1.96; 95% CI, 1.10-3.38; P = .02).

Conclusions: In patients with NAFLD and compensated advanced chronic liver disease, baseline LSM and change in LSM are associated with risk of liver-related events and mortality.
