Abstract The relationship between hepatic encephalopathy (HE) and the sleep-wake disturbances exhibited by patients with cirrhosis remains debated. The aim of this study was to examine the usefulness of sleep-wake interview within the context of HE assessment. One-hundred-and-six cirrhotic patients were asked three yes/no questions investigating the presence of difficulty falling asleep, night awakenings and daytime sleepiness. All underwent formal HE assessment, quantitative electroencephalography and standardised psychometry. Fifty-eight were monitored for 8 ± 6 months in relation to the occurrence of HE. Patients complaining of daytime sleepiness (n = 75, 71 %) had slower EEGs than those who did not report it (relative alpha power: 37 ± 19 vs. 48 ± 17 %, p < 0.05). In addition, daytime sleepiness was associated with the presence of portal-systemic shunt (79 vs. 57 %, p < 0.05) and HE history (72 vs. 45 %, p < 0.05). Finally, the absence of excessive daytime sleepiness had a Negative Predictive Value of 92 % (64–100) in relation to the development of HE during the follow-up period. These data support the appropriateness of adding a yes/no question on the presence of excessive daytime sleepiness to routine assessment of patients with cirrhosis, to help identify those who do not need further, formal HE screening.

Abstract

Abstract The relationship between hepatic encephalopathy (HE) and the sleep-wake disturbances exhibited by patients with cirrhosis remains debated. The aim of this study was to examine the usefulness of sleep-wake interview within the context of HE assessment. One-hundred-and-six cirrhotic patients were asked three yes/no questions investigating the presence of difficulty falling asleep, night awakenings and daytime sleepiness. All underwent formal HE assessment, quantitative electroencephalography and standardised psychometry. Fifty-eight were monitored for 8 ± 6 months in relation to the occurrence of HE. Patients complaining of daytime sleepiness (n = 75, 71 %) had slower EEGs than those who did not report it (relative alpha power: 37 ± 19 vs. 48 ± 17 %, p < 0.05). In addition, daytime sleepiness was associated with the presence of portal-systemic shunt (79 vs. 57 %, p < 0.05) and HE history (72 vs. 45 %, p < 0.05). Finally, the absence of excessive daytime sleepiness had a Negative Predictive Value of 92 % (64–100) in relation to the development of HE during the follow-up period. These data support the appropriateness of adding a yes/no question on the presence of excessive daytime sleepiness to routine assessment of patients with cirrhosis, to help identify those who do not need further, formal HE screening.
