Abstract
OBJECTIVE Sleep loss is common in patients with liver injury, but the effects of sleep deprivation (SD) on liver injury remain unclear. In the present study, the potential effects of SD on acute liver injury and the underlying mechanisms have been investigated. METHODS The sleep of male BALB/c mice has been deprived by using a modified multiple platform water bath for 3 days and acute liver injury was induced by intraperitoneal injection of lipopolysaccharide (LPS) and D-galactosamine (D-Gal). The degree of liver injury was detected by aminotransferase determination, histopathology and survival rate analysis. Inflammatory response and melatonin (MT) were measured by enzyme-linked immunosorbent assay (ELISA). In addition, hepatocyte apoptosis was determined by caspase activity measurement and terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) assay. RESULTS We observed that SD increased plasma aminotransferases, TUNEL-positive hepatocytes, histological abnormalities and mortality rates in mice with LPS/D-Gal treatment. SD also promoted LPS/D-Gal-induced production of TNF-α and upregulated hepatic caspase-8, caspase-9, and caspase-3 activities in LPS/D-Gal-exposed mice. In addition, SD significantly decreased MT contents in plasma of mice with acute liver injury, but supplementation with MT reversed these SD-promoted changes. CONCLUSION Our data suggested that SD exacerbated LPS/D-Gal-induced liver injury via decreasing melatonin production.

Low-dose melatonin for sleep disturbances in early-stage cirrhosis: A randomized, placebo-controlled, cross-over trial. JGH OPEN 2020; 4:749-756. [PMID: 32782966 PMCID: PMC7411556 DOI: 10.1002/jgh3.12356] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 02/20/2020] [Revised: 04/08/2020] [Accepted: 05/02/2020] [Indexed: 12/16/2022]
Abstract
Background and aim Melatonin is used to treat sleep disturbances (SDs). The aim of this study was to investigate the safety and efficacy of low‐dose melatonin for SDs in early‐stage cirrhosis. Methods In a single‐center, randomized, double‐blind, placebo‐controlled, cross‐over clinical trial, patients with early‐stage (Child‐Turcotte‐Pugh [CTP] class A or B) cirrhosis with SDs, without hepatic encephalopathy, were randomized to placebo or 3 mg of melatonin for 2 weeks. After 2 weeks, the patients were given a washout period of 1 week and crossed over to melatonin or placebo for a further 2 weeks. The Pittsburgh Sleep Quality Index (PSQI) and Epworth Sleepiness Scale (ESS) were used to measure sleep quality and daytime sleepiness, respectively. Analysis of results was based on intention to treat, and linear mixed‐effect models were used to evaluate the effect of melatonin. Analysis was conducted using R‐programming language 3.5.1. Results Seventy one patients were recruited (mean age: 61.9 ± 8.7 years, males: 46 [64.8%], and CTP Class A = 52 [73.2%] and Class B = 19 [26.8%]). Sixty patients completed the study (mean age: 61.7 ± 8.8 years, males: 40 [66.6%], and CTP Class A = 45 [75.0%] and Class‐B = 15 [25.0%]). Two patients dropped out due to adverse events. Nine patients were lost to follow up. Patients given melatonin had a significantly lower PSQI and ESS compared to both pretreatment (P < 0.001) and postplacebo scores (P < 0.001). Incidence of adverse events was similar (two each of abdominal pain, one each of headache, one each of dizziness) in both groups. Conclusion Melatonin seems safe and effective for use in patients with SDs in early‐stage cirrhosis in the short term. However, larger and longer‐term studies to assess efficacy and safety are required before its clinical use can be recommended.

Abstract
Sleep disturbance and excessive daytime sleepiness have been reported in patients with hepatic cirrhosis. The objective of this study was to evaluate daytime somnolence and sleep complaints in a group of 178 patients with cirrhosis compared to a control group. Sleep features and excessive daytime sleepiness were evaluated by the Basic Nordic Sleep Questionnaire (BNSQ) and the Epworth Sleepiness Scale (ESS). We collected clinical and laboratory data, neurological assessment and EEG recordings in cirrhotic patients. Patients with cirrhosis complained of more daytime sleepiness (p<0.005), sleeping badly at least three times a week (p<0.005), difficulties falling asleep (p<0.01) and frequent nocturnal awakening (p<0.005) than controls. We found a poor correlation between sleep disorders and clinical or laboratory parameters. Our results confirm previous literature reports suggesting a high prevalence of sleep disturbance in patients with cirrhosis. Insomnia and daytime sleepiness are the main complaints. Sleep disorders are probably a multifactorial phenomenon.

Abstract
OBJECTIVES Sleep difficulty is common in minimal hepatic encephalopathy (HE) and the mechanisms are not fully elucidated. Dysregulated histamine neurotransmission is associated with an altered circadian rhythmicity that is partially restored following central histamine H1 receptor blockade in cirrhotic animals. We studied the effects of the histamine H1 blocker hydroxyzine in sleep alterations in patients with cirrhosis in a double-blind, randomized controlled fashion. METHODS A total of 35 patients (age 56 yr [36-69], Pugh's score 9 [7-12], portosystemic shunt: N = 7) with minimal HE and long-standing sleep difficulties (8 months [4-48]) and free from benzodiazepines were randomized to hydroxyzine 25 mg at bedtime (N = 17) or placebo (N = 18) for a 10-day period. Measurements of sleep behavior using visual analog scale and wrist actigraphy, neuropsychological tests, and protein s100beta serum levels were performed at baseline and at day 10. RESULTS Subjective improvement in sleep was observed in 40% of hydroxyzine-treated patients but in none receiving placebo (P < 0.04). Objectively, 65% of hydroxyzine-treated patients versus 25% of patients under placebo had a >or=30% increase in sleep efficiency as measured by wrist actigraphy (P < 0.04). Neuropsychological tests (Z scores) and protein s100beta levels remained statistically unchanged in both groups. One patient developed an acute episode of encephalopathy reversible upon cessation of hydroxyzine. CONCLUSIONS In contrast to placebo, hydroxyzine 25 mg at bedtime improved sleep behavior (subjectively and using wrist actigraphy) in patients with cirrhosis and minimal HE. The risk of precipitating overt HE warrants some caution when prescribing this drug.

Abstract
There is no "gold standard" for diagnosing hepatic encephalopathy in patients with cirrhosis. In consequence, the presence of this condition, unless floridly overt, is often missed. As a result, the majority of patients are denied the benefits of treatment. There are a number of individual techniques, which access different aspects of cerebral function that can be used, singly or in combination, to provide diagnostic information in this condition, including mental state assessment, psychometric testing, electroencephalography, sensory and cognitive evoked potentials, and neuroimaging. These have been variously applied to the study of hepatic encephalopathy but fundamental differences in the essential aims of the studies, as well as differences in the patient populations and the acquisition and analysis of the data, have made comparisons difficult. Thus, there is no clear consensus as to the sensitivity, specificity, or validity of these tests when used alone or in combination. There are, however, a number of additional methods that could be used to analyze the electrophysiological data, and a number of alternative evoked potentials that could be measured to provide better diagnostic information. In addition, there are a number of techniques, such as critical flicker frequency and smooth pursuit eye movements, which have not yet been applied systematically in this condition and which may provide useful diagnostic information. Clearly the methods for assessing hepatic encephalopathy need to be reviewed, newer methods for analyzing the electrophysiological data and newer techniques for assessing alternative aspects of cerebral function need to be explored for their diagnostic utility. This process should aim at developing a multidimensional diagnostic tool.

Abstract
The circadian variation in some biologic functions may have clinical, fiscal and therapeutic implications. The authors discuss circadian variation in portal pressure in cirrhotic patients and nocturnal occurrence of bleeding from varices in these patients. The pathogenesis of the diurnal variation in portal pressure is presented. The authors submit the hypothesis that an optimal dosing regimen for non-selective beta blocker therapy in the prevention of variceal bleed must include an evening dose of beta blocker medication. In studies reporting comparative efficacy of beta blocker therapy with other modalities in the prevention of variceal bleeding, the optimal dosing schedule for beta blocker therapy must be emphasized.

Abstract
OBJECTIVES The circadian variation in portal blood pressure and in the diurnal incidence of variceal bleeding is well known, but the seasonal variation in variceal bleeding is still controversial. This report analyzes the seasonal variations in mortality and hospitalizations due to variceal bleeding in the French population. METHODS All the deaths due to variceal bleeding that occurred from 1987 to 1996 (N = 13,514) and all adults discharged from French public hospitals for variceal bleeding from 1995 to 1997 (N = 17,026) were examined retrospectively. Cumulated monthly averages were expressed as the percentage above or below the average monthly value during the entire study period. RESULTS Deaths due to variceal bleeding in France occurred with a clear annual periodicity and peaked in winter (December/January), both in the overall population and in subgroups defined by age and sex, except for women. The distribution of cumulative monthly deaths differed by 24%, with a peak (14% above average) in December and a trough (10% below average) in July (Roger's test: p < 0.001). Hospitalizations for variceal bleeding in French public hospitals followed a similar seasonal pattern (p < 0.001) with a winter-spring predominance (4% to 7% from December through April), except in patients aged 15-49 yr. There was a short sharp peak of mortality in early winter in French public hospitals. The seasonality of hospitalization and death increased markedly with age. CONCLUSIONS A better understanding of these age- and sex-specific seasonal patterns would allow to improve pharmacological protection measures, disease management, and educational strategies.

Abstract
Several combined pathogenetic factors such as hyperammonemia, different brain tryptophan metabolic disturbances and serotonin physiological/pharmacological alterations not yet defined in all details, will often give rise to the clinical neuropsychiatric condition known as hepatic encephalopathy (HE). Indeed, to this the probable exposure to novel potent CNS-monoamine acting drugs today may put such patients at certain risk for other pharmacodynamic (PD) responses than usually are expected from these "safe" drugs. Moreover, with a compromised liver function in HE, also pharmacokinetic (PK) features for the drugs are likely changed in these patients. Thus, the ultimate clinical outcome by this probable but unknown PD/PK-deviation for such psychoactive drugs when given to HE-patients needs further clarification. Accordingly, delineation of both PD- and PK-effects in experimental HE should shed light on this issue of relevance for monoamine-active drug safety as well as on some further details in the complex tryptophan/monoamine-related pathophysiology that comes into play in HE.

Abstract
To determine if the extent of portal-systemic shunting (PSS) influences the disruption of circadian function in chronic liver disease, locomotor activity was examined in two rat models with varying degrees of PSS, i.e., portal vein ligation (PVL) and end-to-side portacaval anastomosis (PCA). Animals were housed in individual activity cages under conditions of 12 hour light/12 hour darkness (weeks 0-3), then under conditions of constant dim light (weeks 4-7). Cages were equipped with running wheels connected to a continuous recorder, and daily tracings of running activity were recorded for 7 weeks. Computer analysis of wheel revolutions per hour with a chi 2 periodogram was used to calculate Qp, a measure of the amplitude of a circadian rhythm. The degree of PSS was measured by means of radioactive microspheres injected into the ileocolic vein and spleen. PVL rats were found to have PSS from the splenic and mesenteric territories of 88% and 27%, respectively; circadian periodicity was maintained in all PVL rats. PCA rats had complete shunting (greater than 99%) and showed a range of disrupted circadian rhythms from blunting of the amplitude to complete absence of the locomotor activity rhythm. This spectrum of disorganization occurred in spite of similar degrees of liver atrophy and weight gain. Whereas PCA in rats markedly disturbs the circadian rhythm of locomotor activity, animals with considerably less PSS from PVL exhibit normal behavior. The extent of PSS could be a variable affecting the expression of circadian rhythms in liver disease.

Abstract
To determine whether hepatic encephalopathy may be associated with a disruption of circadian function, the circadian rhythms of locomotor activity and pineal melatonin content were examined in an animal model of complete portal-systemic shunting, rats with a portacaval anastomosis (PCA). The locomotor activity rhythm of all sham-operated animals entrained normally to a light/dark cycle and exhibited a normal free-running period during exposure to constant light. In contrast, PCA led to a dampening of the locomotor activity rhythm in all animals and the abolishment of a circadian periodicity in the activity rhythm of approximately 50% of rats during exposure to either a light/dark cycle or constant light. While normal diurnal variations of pineal melatonin content were seen in sham-operated rats, the amplitude of this variation appeared to be decreased in PCA animals. The similar effects of PCA on both a behavioral and an endocrine circadian rhythm, known to be regulated by a common neural pacemaker, coupled with studies indicating that a variety of other circadian rhythms may be disrupted in both animals and humans with hepatic dysfunction, suggests that this circadian disturbance originates within the pacemaker or on one of its afferent/efferent pathways.

Abstract
The concentrations of catecholamines, serotonin, histamine and GABA as well as some of their precursors and metabolites were measured in the CSF and the serum of human patients at different grades of hepatic encephalopathy. In all grades the CSF concentrations of the neurotransmitters were much increased over control levels, while the amount of metabolites varied with the grade of coma. The data suggest modifications of the cerebral turnover of dopamine, norepinephrine and serotonin. The "false transmitters" also occurred in high concentration in all grades of hepatic coma and could play a role in the alterations of synaptic transmission. The present results suggest that the biochemical changes between grade 2 and grade 4 hepatic coma could be due to an inhibition of dopamine beta-hydroxylase. Moreover, the levels of neurotransmitter precursors, tyrosine and 5-hydroxytryptophan, showed enhancement in grades 2 and 3 followed by an important reduction in grade 4. Finally, it seems that the biogenic amines measured in the CSF are of central origin and that their quantification in human lumbar fluid gives new information on the central mechanisms involved in hepatic encephalopathy.
