A considerable proportion of patients with cirrhosis exhibit insomnia, delayed sleep habits, and excessive daytime sleepiness. These have been variously attributed to hepatic encephalopathy and impaired hepatic melatonin metabolism, but the understanding of their pathophysiology remains limited and their treatment problematic. Sleep is regulated by the(More)
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(More)
HRQoL is impaired in cirrhosis. Establishing the relevance of depression, anxiety, alexithymia and cirrhosis stage on the patients’ HRQoL. Sixty cirrhotics underwent a neuropsychological assessment, including ZUNG-SDS, STAI Y1-Y2 and TAS-20. Minimal hepatic encephalopathy (MHE) was detected by PHES, HRQoL by Short-Form-36 (SF-36). Depression was detected in(More)
Bright times for patients with cirrhosis and delayed sleep habits: a case report on the beneficial effect of light therapy Light therapy for sleep disturbance in cirrhosis Word count 615 To the Editor: In February 2011, an 82-year-old female was admitted into hospital for a chest infection. She had a history of viral cirrhosis, with a previous, minor(More)
Hyperammonaemia is observed after prolonged, intense exercise, or in patients with hepatic failure. In the latter, it is associated with a set of neurological and psychiatric abnormalities termed hepatic encephalopathy. The aims of our study were: 1. to measure vigilance in a condition of induced hyperammonaemia; 2. to assess whether caffeine modulates the(More)
European Association for the Study of the Liver 1 Ascites is the most common complication of cirrhosis, and 60% of patients with compensated cirrhosis develop ascites within 10 years during the course of their disease [1]. Ascites only occurs when portal hypertension has developed [2] and is primarily related to an inability to excrete an adequate amount of(More)
BACKGROUND Epidemiological studies indicate that a growing number of cirrhotic patients will develop hepatocellular carcinoma (HCC) in the next decade. Recent findings have demonstrated that Squamous cell carcinoma antigen 1 (SCCA1) and 2 (SCCA2) isoforms, now classified as serpinB3 and serpinB4, are over-expressed in HCC, but not in normal liver. As(More)
The physiological roles of the protease inhibitor SERPINB3 (SB3) are still largely unknown. The study was addressed to assess the biological effects of this serpin in vivo using a SB3 transgenic mouse model. Two colonies of mice (123 transgenic for SB3 and 148 C57BL/6J controls) have been studied. Transgenic (TG) mice showed longer survival than controls(More)
INTRODUCTION Sleep-wake disturbances are common in hospitalized patients but few studies have assessed them systematically. The aim of the present study was to assess sleep quality in a group of medical inpatients, in relation to environmental factors, and the switch to daylight-saving time. METHODS Between March and April 2013, 118 consecutive inpatients(More)
