While there is widespread acceptance of its importance, there is no consensus on how best to diagnose and monitor HE. Objective To compare the four most favoured methods for the diagnosis of HE. Design 170 patients who were on the waiting list for liver transplantation as well as 86 healthy controls were included in the study. All patients and controls underwent the portosystemic encephalopathy syndrome test yielding the psychometric hepatic encephalopathy score (PHES), the repeatable battery for the assessment of neuropsychological status (RBANS), the inhibitory control test (ICT) and critical flicker frequency (CFF) measurement. Results PHES and ICT targets had the best sensitivity (85.7% vs 85.7%) and specificity (96.5% vs 97.6%) for the diagnosis of overt HE. CFF showed inferior sensitivity (40.9%) for the diagnosis of HE and dependency from previous alcohol abuse (p=0.015). Multiple regression analysis showed that all test results apart from PHES were influenced by secondary diagnoses such as diabetes mellitus and renal insufficiency. Conclusions In the German population of patients awaiting liver transplantation, PHES is the most robust method for the diagnosis and follow-up of HE. ER -
