Background/AimsThe aim of our study was to provide a predictive model for early recognition of the risk of short-term development of hepatic encephalopathy (HE) in patients with symptomatic acute liver disease (ALD).MethodsFrom a retrospective analysis of 220 patients with ALD, prothrombin time (PT) equal to, or lower than, 80% of normal, was set as the registration criteria in the subsequent patient cohorts of the study. Then, a HE-prediction model was derived by a logistic regression analysis of data in 259 new patients, and prospectively validated in 124 other patients, both groups of patients were affected by ALD unrelated to paracetamol (non-P ALD).ResultsThe following HE-prediction model was established: lambda=[0.692Ãln(1+total bilirubin(mg/dL))]-[0.065ÃPT(%)]+[1.388ÃAge(years)]+[0.868ÃEtiology]-1.156,where Age is 1 in patients older than 50Â years and Etiology is 1 when the cause of non-P ALD is flare-up of type B hepatitis, auto-immune hepatitis or unknown, and 0 otherwise. In the validation group, according to the model-based risk of subsequent development of HE, sensitivity and specificity of the model were 100% and 69.0%, respectively, in patients with an evaluated risk lower than 20%, and 62.5% and 93.1%, respectively, in those with an evaluated risk equal to, or greater than, 50%.ConclusionIn Japanese patients with symptomatic non-P ALD, our model, which includes four of the five items used in the King's College Hospital criteria, represents an acceptable, effective model to allow early detection of the risk of short-term development of HE. Using this model in other populations requires further validation specific to each of them.
