BACKGROUND AND AIMS:Minimal hepatic encephalopathy (MHE) is associated with poor quality of life and increased work disability in cirrhotic patients. Its prevalence in extrahepatic portal vein obstruction (EHPVO) is not known. We studied the prevalence of MHE in EHPVO patients and utility of critical flicker frequency (CFF) for diagnosing MHE.PATIENTS AND METHODS: Thirty-four EHPVO patients with a history of variceal bleed (age 23.2 ± 11.2 yr, M:F 22:12) diagnosed by either Doppler US or MR angiography, which demonstrated portal vein obstruction and/or portal vein cavernoma, were evaluated by psychometry (number connection tests A, B or figure connection tests A, B) and P300 auditory event-related potential (P300ERP). CFF was also evaluated. MHE was diagnosed by abnormal psychometry (|2 standard deviation [SD]) and/or P300ERP (|2.5 SD).RESULTS:Prevalence of MHE (N = 12) was 35.3%. Of 34 patients, P300ERP was abnormal (380.0 ± 28.9 msec) in 11 (32%), psychometry in 9 (26.4%), both P300ERP and
Development of hepatic encephalopathy in a patient with cirrhosis is associated with poor survival rate of 10-70% at one year depending upon hepatic and renal functions. Treating patients to prevent development of first episode of hepatic encephalopathy is classified as primary prophylaxis of hepatic encephalopathy and preventing recurrence of hepatic encephalopathy in patients who had previous episode of hepatic encephalopathy is secondary prophylaxis of hepatic ...
Hepatic encephalopathy encompasses a spectrum or continuum of disease and, consequently, the symptoms and severity of the disorder can vary widely from one person to another. The severity of hepatic encephalopathy can range from mild, barely discernable symptoms to serious, life-threatening complications. Hepatic encephalopathy may develop slowly over time in individuals with chronic liver disease or may occur episodically, worsening and then improving only to recur. An episode of hepatic encephalopathy is often triggered by certain conditions such as infection, gastrointestinal bleeding, constipation, certain drugs, surgery or an alcohol binge. Episodes of hepatic encephalopathy can develop rapidly and without warning, often necessitating hospitalization.. It is important to note that affected individuals may not have all of the symptoms discussed below. Affected individuals should talk to their physician and medical team about their specific case, associated symptoms and overall prognosis. ...

OBJECTIVES:The aim of this study was to determine whether the number connection test (NCT) times of a group of cirrhotic patients without clinically overt hepatic encephalopathy and a group of healthy patients without liver disease who were undergoing endoscopy were prolonged after sedation with short acting i.v. benzodiazepines.METHODS:All patients were administered the NCT in a standard fashion for 30 min before sedation for an upper GI endoscopy and then 2 h after sedation postprocedure. Two NCTs were carried out before and 2 h after sedation, and the mean of the tests pre- and postsedation calculated. Based on the upper limit of the 95% CI of the presedation NCT of patients without liver disease as the cut-off level for hepatic encephalopathy, the proportion of cirrhotic patients with subclinical encephalopathy before and after sedation were also determined.RESULTS:A total of 61 consecutive cirrhotic patients who underwent therapeutic upper GI endoscopy completed the study. The mean ...
There are various explanations why liver dysfunction or portosystemic shunting might lead to encephalopathy. In healthy subjects, nitrogen-containing compounds from the intestine, generated by gut bacteria from food, are transported by the portal vein to the liver, where 80-90% are metabolised through the urea cycle and/or excreted immediately. This process is impaired in all subtypes of hepatic encephalopathy, either because the hepatocytes (liver cells) are incapable of metabolising the waste products or because portal venous blood bypasses the liver through collateral circulation or a medically constructed shunt. Nitrogenous waste products accumulate in the systemic circulation (hence the older term "portosystemic encephalopathy"). The most important waste product is ammonia (NH3). This small molecule crosses the blood-brain barrier and is absorbed and metabolised by the astrocytes, a population of cells in the brain that constitutes 30% of the cerebral cortex. Astrocytes use ammonia when ...

Abstract Background & Aims Episodic hepatic encephalopathy is frequently precipitated by factors that induce circulatory dysfunction, cause oxidative stress-mediated damage or enhance astrocyte swelling. The administration of albumin could modify these factors and improve the outcome of hepatic encephalopathy. The aim of this study is to assess the efficacy of albumin in a multicenter, prospective, double-blind, controlled trial (ClinicalTrials.gov number, NCT00886925). Methods Cirrhotic patients with an acute episode of hepatic encephalopathy (grade ...
This is a prospective study designed to examine the role of bacterial overgrowth and delayed intestinal transit and the effect of Rifaximin with hepatic encephalopathy (HE). This study is divided into Phase A and Phase B. The purpose of Phase A is to test patients with cirrhosis to determine if they have bacterial overgrowth which may lead to slow intestinal transit and hepatic encephalopathy. The purpose of Phase B is to investigate whether the improvement found in patients with hepatic encephalopathy taking Rifaximin is also related to decreased bacterial overgrowth.. Subjects mental capacity will be assessed at each visit via interview, brief mental status, questionnaires and psychometric evaluation. Any subject who appears to have lost capacity to continue participation, as evidenced by HE grade 2 or higher, a lack of attentiveness, concentration, or understanding of evaluation, will be discontinued from the study. Female subjects of childbearing potential will be asked to comply with the ...
A comatose state in a patient with a history of chronic alcoholism or chronic liver disease may be due to causes other than hepatic encephalopathy. For correct therapy it is necessary to establish whether such a patient is actually suffering from a hepatic encephalopathy or from some other conditions producing coma. Since blood ammonia levels in hepatic coma vary greatly, we have determined the glutamine level in the cerebrospinal fluid (CSF) of such patients.. We have diagnosed hepatic coma by the elevated glutamine levels (above 30 mg) in the CSF. This diagnosis was confirmed later by the clinical course, liver ...

Hepatic encephalopathy is caused by disorders affecting the liver. These include disorders that reduce liver function (such as cirrhosis or hepatitis) and conditions where blood circulation bypasses the liver. The exact cause of the disorder is unknown. The liver cannot properly metabolize and detoxify substances in the body. Accumulation of toxic substances causes metabolic abnormalities that lead to damage in the central nervous system (brain and spinal cord). The most common toxic substance is ammonia, which is produced by the body when proteins are digested, but normally is detoxified by the liver. Many other substances also accumulate in the body and damage the nervous system.. In people with otherwise stable liver disorders, hepatic encephalopathy may be triggered by episodes of gastrointestinal bleeding, excessive dietary protein, or electrolyte abnormalities (especially decrease in potassium, which may result from vomiting or treatments such as diuretics or paracentesis). The disorder ...
TY - JOUR. T1 - The role of astrocytes in hepatic encephalopathy. AU - Norenberg, Michael D. PY - 1987/2/1. Y1 - 1987/2/1. N2 - The Alzheimer type II astrocyte change is the distinctive morphologic alteration in brain of humans and experimental animals succumbing to hepatic encephalopathy (HE). Whether this change is a primary event in the pathogenesis of HE or whether it is secondary to injury of some other component(s) of the CNS has not been clarified. Studies in a rat model of HE have revealed early reactive changes in astrocytes characterized by cytoplasmic hypertrophy. During the later phases, degenerative changes ensue corresponding to the Alzheimer type II change observed by light microscopy. In view of the role of astrocytes in ammonia detoxification and the importance of ammonia in the pathogenesis of HE, we have suggested that the initial astrocytic changes are the morphological correlates of ammonia detoxification. We have speculated that the later degenerative alterations could lead ...
Gastroenterology faculty, nurse practitioners and physician assistants had excellent concordance in classifying grade 2 or higher hepatic encephalopathy compared with gastroenterology and hepatology physicians, according to a recently published study.

A late stage liver condition, known as minimal hepatic encephalopathy (MHE), is associated with impaired driving skills and greater risk of motor vehicle accidents. Cost analysis of management strategies for detection and treatment of MHE are published in the April issue of Hepatology, a journal of the American Association for the Study of Liver Diseases.
Abnormal circadian rhythms have been described for several biological parameters in cirrhosis. The existence of a "biologic clock" in the SCN allows the body to anticipate external environment modifications during the day-night cycle. Current views propose two explanations for circadian alterations seen in chronic liver disease. According to the first hypothesis, circadian rhythm abnormalities arise from the effect of neurotoxins on the SCN and/or its afferent/efferent connections. According to the second hypothesis, impaired hepatic melatonin clearance, probably due to decreased liver blood flow, lower 6-beta-hydroxylase activity, and competition with bilirubin in the intrahepatic transport system [14, 20-22], results in elevated morning melatonin levels, thereby causing a circadian clock phase-shift. It is possible that both proposed mechanisms, by combining the effects of hepatocellular dysfunction and portal systemic shunting, are responsible for circadian abnormalities in liver disease [1, ...
The purpose of the present investigation was to study changes in cerebral blood flow (CBF) in hepatic encephalopathy, to ascertain whether this was related to the changes in liver function and whether these changes gave any prognostic information. CBF, determined by the intravenous xenon-133 method, and liver functions, assessed by the prothrombin index, bilirubin concentration, and the galactose elimination capacity, were studied in patients with acute fulminant liver failure and in patients with encephalopathy due to chronic liver diseases--that is, cirrhosis of various etiologies. The CBF range in healthy young subjects (age, 23-42 years) was 44-61 ml/100 g/min; in patients with grade I + II encephalopathy (mean +/- SEM) it was 32.8 +/- 3.6 ml/100 g/min in acute (n = 4; age, 28 +/- 8 years) and 37.0 +/- 3.3 ml/100 g/min in chronic liver patients (n = 10; age, 51 +/- 2 years). In grade III + IV encephalopathy it was 28.7 +/- 3.8 ml/100 g/min in acute (n = 8; age, 28 +/- 3 years) and 32.9 +/- ...
WASHINGTON -- The FDA approved the travelers diarrhea drug rifaximin (Xifaxan) for the risk recurrence reduction of overt hepatic encephalopathy in patients with advanced liver disease.
Hepatic encephalopathy (HE) is a cause of significant morbidity and mortality in patients with liver disorders and a wide range of rodent models of HE have been described to facilitate studies into the pathogenesis and treatment of HE. However, it is widely acknowledged that no individual model perfectly mimics human HE and there is a particular need for spontaneous, larger animal models. One common congenital abnormality in dogs is the portosystemic shunt (cPSS) which causes clinical signs that are similar to human HE such as ataxia, disorientation, lethargy and occasionally coma. As inflammation has recently been shown to be associated with HE in humans, we hypothesised that inflammation would similarly be associated with HE in dogs with cPSS. To examine this hypothesis we measured C-reactive protein (CRP) in 30 healthy dogs, 19 dogs with a cPSS and no HE and 27 dogs with a cPSS and overt HE. There was a significant difference in CRP concentration between healthy dogs and dogs with HE (p , ...

Hepatic encephalopathy in cirrhosis is contributed to by toxic products deriving from the proteolytic bacterial flora related degradation of dietary nitrogen substances.. Acarbose is a novel hypoglycemic agent acting through the inhibition of glucose absorption in the gut and the promotion of intestinal saccharolytic bacterial flora at the expense of proteolytic flora.. Dr Gentile and colleagues from Naples, Italy undertook a study in order to assess whether acarbose exerts a beneficial effect on hepatic encephalopathy and on postprandial hyperglycemia.. The researchers included cirrhotic patients with low-grade hepatic encephalopathy and type 2 diabetes mellitus in the study.. In total, the research team randomized 107 cirrhotic patients with grade 1 2 hepatic encephalopathy and type 2 diabetes mellitus to acarbose 100 mg 3 times daily or placebo for 8 weeks.. The researchers then switched the patients treatments after a 2-week washout period and patients were then followed for 8 more ...
Hepatic encephalopathy (HE) is a well-recognised complication of cirrhosis, which is associated with considerable morbidity and mortality. Subtle signs of HE are observed in approximately 60%1 and overt HE (OHE) in about 30-45% of patients with cirrhosis.2 After a first OHE episode, the 1-year cumulative probability of recurrence is 40%,3 and the 1-year and 3-year survival probabilities are 42% and 23%, respectively.4 The mortality risk associated with HE is higher than that associated with other major hepatic decompensation events.5 HE can adversely affect patients quality of life (QoL) and cognitive function.6 ,7 Furthermore, because OHE requires hospital management, it places a considerable burden on healthcare resources.8. Treatment for HE aims to resolve OHE episodes and prevent recurrences.9 Rifaximin-α (TARGAXAN, Norgine) is a minimally absorbed, oral antibiotic which has been shown, in clinical trials, to reduce the risk of OHE episodes, HE-related hospitalisations and improve ...
ELPA and Norgine have launched a patient leaflet to improve the early detection of hepatic encephalopathy, and a patient passport to facilitate conversations with healthcare professionals. Hepatic encephalopathy remains under-diagnosed and under-treated, as many patients and carers are unaware of the signs and symptoms of the disease. In addition, healthcare providers dont always identify and treat the often subtle symptoms of hepatic encephalopathy, and this can lead to poor patient outcomes and increased hospital admissions.1 Hepatic encephalopathy is a significant complication of advanced chronic liver disease, and occurs in up to 40% of patients or as many as 200,000* people in Europe. 1, ...

Patients with minimal hepatic encephalopathy (MHE) show neurological impairment in specific tasks to which selective regional alterations in blood flow (BF) could contribute. Arterial spin labeling (ASL), a non-invasive magnetic resonance technique, quantitatively measures cerebral perfusion. We analyzed BF by ASL in different brain areas of controls and cirrhotic patients without and with MHE. We found that BF is more affected in cerebellum than in other areas of cirrhotic patients and that BF determination in cerebellum using ASL may detect MHE earlier than the Psychometric Hepatic Encephalopathy Score battery. Altered nitric oxide-cGMP pathway seems to be associated to altered BF in cerebellum ...

Brain manganese deposition is led by liver dysfunction and/or portal-systemic shunting in minimal hepatic encephalopathy (MHE). Manganese is toxic and can cause cognitive disorders and extrapyramidal symptoms. Thus, reduction of manganese intake might be considered as a potential treatment strategy for MHE. In this study we aimed to investigate whether low- or no-manganese feed can improve the neuropsychological manifestations in MHE rats. Rats with MHE were established by partially ligating the portal vein and fed a manganese diet (MHE-M, 10mg per kg feed; n=24), a no-manganese diet (MHE-N; n=24) and a half-manganese diet (MHE-H; n=24) for 2, 4, 6 and 8weeks, with six rats in each subgroup ...
