Enhanced liver fibrosis score is stable after withdrawal in patients with heavy alcohol consumption: A pilot study

Abstract

AbstractBackgroundEnhanced liver fibrosis (ELF) score is an accurate, noninvasive test for assessing the severity of liver fibrosis in chronic liver disease, including alcohol‐related liver disease. However, whether the ELF score changes during alcohol withdrawal is unknown. This pilot study assessed changes in the ELF score during withdrawal in patients with a history of excessive alcohol intake.MethodsIn this prospective study, ELF was performed on day 0 (D0, at the beginning of hospitalization), at day 7 (D7, on discharge from hospital), and at follow‐up visits on days 30 (D30) and 90 (D90). Transient elastography (TE) was also assessed on days 4 (D4) and D30.ResultsThe study included 35 patients (71% male) with a mean alcohol intake of 139 g/day. On D30 and D90, 8 and 13 patients had resumed alcohol consumption (mean intake of 90 and 80 g/day, respectively). In patients who remained abstinent, the mean ELF score was 8.93 on D0, 9.14 on D30 (p = 0.32), and 9.27 on D90 (p = 0.14). In patients who resumed alcohol, mean ELF score was 9.7 on D0, 10.05 on D30 (p = 0.09), and 9.71 on D90 (p = 0.12). ELF score was comparable over the first months after withdrawal, although there was a slight increase in the first week (mean ELF score increased from 9.24 on D0 to 9.74 on D7, p < 0.001). Mean TE value was 7.9 kPa on D4 and 8.1 kPa on D30 (p = 0.84) in patients who resumed alcohol consumption, and 8.3 and 7.5 kPa (p = 0.03) on D4 and D30, respectively, in abstinent patients.ConclusionThe ELF score is stable during the first months after withdrawal and thus appears to be a useful tool to assess liver fibrosis or cirrhosis in this setting. Nevertheless, because in the first week there is a transient increase in ELF score, caution in interpretation is warranted.
