FORWARD In March 2001, the National Institutes of Health issued the following warning: "The number of Web sites offering health-related resources grows every day. Many sites provide valuable information, while others may have information that is unreliable or misleading."1 Furthermore, because of the rapid increase in Internet-based information, many hours can be wasted searching, selecting, and printing. Since only the smallest fraction of information dealing with hepatic encephalopathy is indexed in search engines, such as www.google.com or others, a non-systematic approach to Internet research can be not only time consuming, but also incomplete. This book was created for medical professionals, students, and members of the general public who want to know as much as possible about hepatic encephalopathy, using the most advanced research tools available and spending the least amount of time doing so. In addition to offering a structured and comprehensive bibliography, the pages that follow will tell you where and how to find reliable information covering virtually all topics related to hepatic encephalopathy, from the essentials to the most advanced areas of research. Public, academic, government, and peer-reviewed research studies are emphasized. Various abstracts are reproduced to give you some of the latest official information available to date on hepatic encephalopathy. Abundant guidance is given on how to obtain free-of-charge primary research results via the Internet. While this book focuses on the field of medicine, when some sources provide access to non-medical information relating to hepatic encephalopathy, these are noted in the text. E-book and electronic versions of this book are fully interactive with each of the Internet sites mentioned (clicking on a hyperlink automatically opens your browser to the site indicated). If you are using the hard copy version of this book, you can access a cited Web site by typing the provided Web address directly into your Internet browser. You may find it useful to refer to synonyms or related terms when accessing these Internet databases. NOTE: At the time of publication, the Web addresses were functional. However, some links may fail due to URL address changes, which is a common occurrence on the Internet. For readers unfamiliar with the Internet, detailed instructions are offered on how to access electronic resources. For readers unfamiliar with medical terminology, a comprehensive glossary is provided. For readers without access to Internet resources, a directory of medical libraries, that have or can locate references cited here, is given. We hope these resources will prove useful to the widest possible audience seeking information on hepatic encephalopathy. The Editors

CHAPTER 1. STUDIES ON HEPATIC ENCEPHALOPATHY Overview In this chapter, we will show you how to locate peer-reviewed references and studies on hepatic encephalopathy.
The Combined Health Information Database The Combined Health Information Database summarizes studies across numerous federal agencies. To limit your investigation to research studies and hepatic encephalopathy, you will need to use the advanced search options. First, go to http://chid.nih.gov/index.html. From there, select the “Detailed Search” option (or go directly to that page with the following hyperlink: http://chid.nih.gov/detail/detail.html). The trick in extracting studies is found in the drop boxes at the bottom of the search page where “You may refine your search by.” Select the dates and language you prefer, and the format option “Journal Article.” At the top of the search form, select the number of records you would like to see (we recommend 100) and check the box to display “whole records.” We recommend that you type “hepatic encephalopathy” (or synonyms) into the “For these words:” box. Consider using the option “anywhere in record” to make your search as broad as possible. If you want to limit the search to only a particular field, such as the title of the journal, then select this option in the “Search in these fields” drop box. The following is what you can expect from this type of search: •
Hepatic Encephalopathy: Metabolic Consequence of Cirrhosis Often is Reversible Source: Postgraduate Medicine. 109(2): 52-54, 57-60, 63-65, 69-70. February 2001. Contact: Available from McGraw-Hill, Inc. 1221 Avenue of the Americas, New York, NY 10020. (612) 832-7869. Summary: This article discusses hepatic encephalopathy, a condition characterized by neuropsychiatric manifestations ranging from a slightly altered mental status to coma, and neuromuscular symptoms may be present. This complication of chronic or acute liver disease is a result of the failure of the liver to detoxify toxins originating in the intestine. The pathogenesis (how it occurs) probably is multifactorial, although the predominant causative agent appears to be ammonia. About 30 percent of patients with
4
Hepatic Encephalopathy
cirrhosis (scarring of the liver) die in hepatic coma. The molecular basis of neurotoxicity of ammonia or other agents implicated in the condition is poorly understood. Therapy includes timely recognition and correction of precipitating factors. Once the condition is manifested, standard therapy is acute administration of lactulose, a disaccharide that is undigested in the small intestine. The beneficial action of lactulose is not fully understood. The use of oral antibiotics and BCAAs (branched chain amino acids) is of some benefit in patients who do not respond to lactulose. Limitation of protein in the diet may be useful for short periods but is not recommended for long term use because of potential worsening of already poor nutrition. The ultimate therapy for hepatic encephalopathy is orthotopic liver transplantation. Future research will likely focus on the correction of alterations in neurotransmission. 2 figures. 4 tables. 20 references. •
Hepatic Encephalopathy: Current Approaches Source: Contemporary Gastroenterology. 4(3): 51-56. May-June 1991. Summary: This article discusses the current approaches to treating hepatic encephalopathy, focusing on portal-systemic encephalopathy, a reversible metabolic disorder seen almost exclusively in patients with cirrhosis and portal hypertension. The authors suggest limiting protein intake and administering lactulose, once other causes of altered mental status have been eliminated and the precipitating factors have been identified and treated. Liver transplantation may be necessary if this therapy is not helpful and the syndrome recurs. 3 tables. 41 references. (AA-M).

Complications of Cirrhosis: Ascites and Hepatic Encephalopathy Source: Current Opinion in Gastroenterology. 6(3): 365-369. June 1990. Summary: This article discusses two of the complications of cirrhosis: ascites and hepatic encephalopathy. Ascites is the most common complication of cirrhosis. It is associated with about 50 percent of deaths in these patients. Hepatic encephalopathy (HE) is the metabolic effect of liver failure on the central nervous system. Permanent structural changes in the central nervous system do not occur and the syndrome is completely reversible. The clinical course and treatment for both of these conditions is considered in detail, with numerous citations to current research. 23 annotated references.

Hepatic Encephalopathy, Revisited (Editorial) Source: Liver Update Function and Disease. 6(4): 1-2. Fall 1992. Summary: This article presents a brief overview of hepatic encephalopathy. Topics include brain edema in acute liver failure; post-shunt encephalopathy; subclinical encephalopathy; research studies that compare treatments for patients with chronic hepatic encephalopathy; how ammonia affects brain function; and the use of flumazenil, a benzodiazepine receptor antagonist, for treatment of hepatic encephalopathy. The author concludes that newer drugs should provide insight into the pathogenesis of hepatic failure and improve the management of encephalopathy.

Summary: This article reviews the evidence concerning efficacy and safety of the use of parenteral nutritional support (also called total parenteral nutrition or TPN) in three clinical situations: as a primary therapy for patients with inflammatory bowel disease, for patients with acute renal failure, and for patients with hepatic cirrhosis resulting in encephalopathy. For each of the three situations, the rationale, efficacy, safety, and recommendations for using TPN are given. The authors conclude that the true value of parenteral nutritional support in these three clinical indications remains unknown. It is possible that future clinical trials will demonstrate the value of parenteral nutrition for these patients or for subgroups of these patients. 32 references. •
Hepatic Encephalopathy and Ascites Source: Lancet. 350(9087): 1309-1315. November 1, 1997. Summary: This professional education article discusses hepatic encephalopathy and ascites. Hepatic encephalopathy (HE) is a neuropsychiatric syndrome that occurs only with significant liver dysfunction and has a potential for full reversibility. Two distinct forms (overt and subclinical) can be identified in patients with cirrhosis. Various methods have been described for estimating the severity of HE, but the authors encourage the use of the West-Haven criteria for grading mental state in hepatitic encephalopathy. The authors report on recent developments in the pathogenesis of HE, including alterations in the blood-brain barrier, changes in energy metabolism, the role of gut-derived factors, and changes in cerebral neurotransmission. The authors then review the principles of management of HE, including reduction of ammonia toxicity, cerebral neurotransmission, and other approaches. The second half of the article addresses the problem of ascites in patients with cirrhosis, a major cause of morbidity and a serious prognostic development in these patients. The authors consider the pathogenesis of ascites, including the retention of sodium, retention of water, and the hepatorenal syndrome. The article concludes with a discussion of the management of ascites. 3 figures. 1 table. 62 references.
Federally Funded Research on Hepatic Encephalopathy The U.S. Government supports a variety of research studies relating to hepatic encephalopathy. These studies are tracked by the Office of Extramural Research at the National Institutes of Health.2 CRISP (Computerized Retrieval of Information on Scientific Projects) is a searchable database of federally funded biomedical research projects conducted at universities, hospitals, and other institutions. Search the CRISP Web site at http://crisp.cit.nih.gov/crisp/crisp_query.generate_screen. You will have the option to perform targeted searches by various criteria, including geography, date, and topics related to hepatic encephalopathy. For most of the studies, the agencies reporting into CRISP provide summaries or abstracts. As opposed to clinical trial research using patients, many federally funded studies use animals or simulated models to explore hepatic encephalopathy. The following is typical of

Project Title: EFFECT OF CIRRHOSIS AND SHUNTS ON DRUG DISPOSITION Principal Investigator & Institution: Gorski, J. Christopher.; Associate Professor of Medicine; Medicine; Indiana Univ-Purdue Univ at Indianapolis 620 Union Drive, Room 618 Indianapolis, in 462025167 Timing: Fiscal Year 2002; Project Start 15-AUG-2002; Project End 31-JUL-2007 Summary: (provided by applicant): It is well established that hepatic cirrhosis results in reduced clearance of drugs that are highly metabolized and an enhanced sensitivity to the pharmacological and adverse actions of drugs. Chronic alcohol consumption and hepatitis C are the two most common causes of cirrhosis in the United States with an incidence of 3.1 per 1000 people. The development of portal hypertension is the primary mechanism behind several major complications of cirrhosis such as bleeding from gastroesophageal varices, hepatic encephalopathy, and ascites. Transjugular intrahepatic portosystemic shunts (TIPS) and other surgical shunts are performed to manage these complications of portal hypertension. We have demonstrated that in addition to a reduction in hepatic clearance, cirrhotic patients with TIPS experience an increase in intestinal availability of midazolam, a selective cytochrome P450 3A (CYP3A) substrate. This increased bioavailability primarily reflects a functional lack of intestinal wall first-pass metabolism relative to cirrhotics without TIPS and healthy volunteers. The mechanism for this lack of intestinal wall metabolism is unknown. We propose to characterize the mechanism and consequences of this loss of intestinal wall CYP3A activity in cirrhotics with TIPS by directly examining the CYP3A protein and mRNA levels, intestinal permeability, and in vivo hepatic and intestinal CYP3A activity before, immediately after, and I month after TIPS placement. Cirrhotic patients with TIPS, and potentially other types of portosystemic shunts, are expected to be at risk for excessive

pharmacological effects or suffer from an increased incidence of adverse reactions following CYP3A substrate administration. We will examine the susceptibility of these individuals to adverse drug reactions and drug-drug interaction by examining the ability of erythromycin to prolong the QT interval and clarithromycin to inhibit metabolism of buspirone, a CYP3A substrate. Finally, the expression of other enzymes such as UDP-glucuronosyltransferases (UGTs), sulfotransferases (SULTs) and pglycoprotein may also be altered in cirrhosis. We will characterize the changes in these enzymes using the partial clearance of acetaminophen to glucuronide (UGT) and sulfate (SULT) conjugates and the disposition of fexofenadine in cirrhotics with and without TIPS and healthy volunteers.

Project Title: EXPRESSION OF AMMONIA-SENSITIVE PROTEINS IN THE CNS Principal Investigator & Institution: Weiner, I. David.; Associate Professor; Medicine; University of Florida Gainesville, Fl 32611 Timing: Fiscal Year 2004; Project Start 01-DEC-2003; Project End 30-NOV-2005 Summary: (provided by applicant): Encephalopathy due to elevated ammonia levels is a common and costly clinical condition associated either with congenital deficiency of hepatic urea cycle enzymes, with acquired liver disease and with a variety of other conditions. Despite a long recognition that elevated ammonia levels can lead to impaired neurologic functioning, the exact mechanism through which this occurs remains incompletely understood. Moreover, treatment of hyperammonemic encephalopathy has been limited by a lack of knowledge of the specific CNS protein(s) with which ammonia directly interacts. The broad, long-term objective of this project is to examine the hypothesis that Rh C Glycoprotein (RhCG) is a central nervous system (CNS) ammonia 'sensor.' We hypothesize that RhCG protein is expressed in specific CNS neuron populations, that ammonia-stimulation of RhCG is coupled to specific intracellular signaling pathways, most likely including MAP kinase, and that RhCG expression is regulated by specific physiology/pathophysiologic stimuli. We will examine this hypothesis with two specific aims. In the first, we will determine whether ammonia's stimulation of RhCG, or, possibly the related proteins, Rh A Glycoprotein (RhAG) or Rh B Glycoprotein (RhBG), activates specific intracellular signaling pathways in cultured neurons. We will use primary neuronal cultures, and will use RNA interference techniques to inhibit RhCG expression to show specificity of response. In parallel, we will determine whether RhCG can function as an ammonia sensor by determining whether it can complement the pseudohyphal transformation-defect of Amep2-Amep2 S. cerevisiae. To examine the second aim, we will determine whether cecal ligation and puncture-induced sepsis increases CNS expression of either RhCG, or of RhAG or RhBG. These studies will combine immunohistochemical analyses of cellular protein expression patterns with quantitative analyses of protein and mRNA expression with immunoblot and real-time RT-PCR, respectively. These studies fit the purpose of the R21 mechanism in two different manners. These studies will provide pilot data to assess the feasibility of a novel avenue of investigation into the role of RhCG, or related proteins, as CNS ammonia 'sensors.' Second, while these studies are admittedly high risk, their results could lead to a breakthrough in the field of hyperammonemic and hepatic encephalopathy.

Project Title: EXTREME AMMONIA TOLERANCE MECHANISMS: A MODEL VERTEBRATE Principal Investigator & Institution: Walsh, Patrick J.; Marine Biology and Fisheries; University of Miami Coral Gables Box 248293 Coral Gables, Fl 33134 Timing: Fiscal Year 2002; Project Start 08-FEB-2002; Project End 30-NOV-2004 Summary: (provided by applicant): Hepatic Encephalopathy (HE), and resultant elevated blood and tissue ammonia concentrations (i.e., hyperammonemia, HA), has profound central nervous system (CNS) effects, and can have environmental causes. In particular, liver damage due to exposure to toxicants such as carbon tetrachloride, toluene, DDT, heptachlor, etc., as well as chronic alcoholism and direct exposure to environmental ammonia, can elicit symptoms of HE/HA. However, there are such a wide variety of CNS effects produced in the disease in humans, and in rodent experimental models, that it is difficult to determine which disease biomarkers are the most critical indicators of disease progression. Furthermore, characteristics of the rodent model present several weaknesses in the study of HE/HA. Because of this gap in our knowledge, no practical and effective clinical intervention strategies are available to prevent or reverse biomarkers or symptoms of the disease. Recently, we have identified a vertebrate model, the gulf toadfish (Opsanus beta), which is both extremely tolerant of ammonia insult, and which, by virtue of its aquatic lifestyle, enables a line of experimentation not practical in mammalian models, namely rapid "ammonia washout" protocols. Therefore, we propose to test several hypotheses aimed at exploiting these and other characteristics of this new model to address the lack of biomarkers and intervention strategies for HE/HA. In particular, we will: (1) test the hypothesis that there are reversible vs. irreversible biomarkers of HE/HA, and that these can be readily identified and distinguished in an aquatic model like the toadfish; (2) test the hypotheses that extreme ammonia tolerance in the toadfish, relative to mammals, is due to an unusual aspect of its physiology, in particular, either to a more robust ammonia detoxification system in the brain, or to an inherent insensitivity of brain mitochondrial metabolism to ammonia insult. As a further test of this second hypothesis, we will also explore the possibility that the toadfish has higher levels of naturally occurring ammonia protectant compounds (e.g., carnitine, trimethylamine oxide, etc.) in its brain tissues than do mammals. In sum, these experiments will lead to information which is not readily obtainable from humans and existing mammalian models concerning the mechanisms of action of ammonia and cellular capacity for tolerance and recovery, and thus to a better understanding of the causes and mechanisms underlying HE/HA that could lead to therapeutic strategies.

Project Title: MRS STUDIES OF NEUROTRANSMITTER CYCLING IN HUMAN BRAIN Principal Investigator & Institution: Rothman, Douglas L.; Professor; Internal Medicine; Yale University 47 College Street, Suite 203 New Haven, Ct 065208047 Timing: Fiscal Year 2002; Project Start 01-APR-1998; Project End 14-JUN-2003 Summary: Glutamate neurotransmitter release depends on a stable precursor cytosolic glutamate concentration. Loss of glutamate by synaptic release will deplete the nerve terminal cytosolic precursor pool unless compensated for by glutamate reuptake and synthesis. Glial uptake efficiently removes released glutamate from the synaptic cleft in order to maintain a low ECF concentration of glutamate. In vivo and in vitro studies indicate that glutamate taken up by glia is converted to glutamine by glutamine

synthetase. Glutamine is released from the glia to the ECF where it is taken up by neurons and converted back to glutamate through the action of glutaminase. Despite the critical role of this glutamate/glutamine cycle for normal brain function, little is known about the rate or regulation of this pathway. Recently we have developed and tested in the rat brain a model of this pathway which allows the rate of the glutamate/glutamine cycle to be measured from C MRS measurements of glutamine isotopic labeling. The primary objective of this grant is to determine the rate of the glutamate/glutamine cycle in normal human cortex. C MRS will be used to measured glutamine and glutamate isotopic labeling from infused [1-13C] and [2-13C] glucose. Key aspects of the proposed model of the glutamate/glutamine cycle will be tested through measuring of the effect of altering plasma ammonia concentration on total and anapleurotic glutamine synthesis in subjects with mild hepatic encephalopathy.

Project Title: MUSCARINIC RECEPTOR COUPLING TO INOSITIDES IN CNS Principal Investigator & Institution: Fisher, Stephen K.; Professor; Pharmacology; University of Michigan at Ann Arbor 3003 South State, Room 1040 Ann Arbor, Mi 481091274 Timing: Fiscal Year 2003; Project Start 01-SEP-1986; Project End 30-JUN-2007 Summary: (provided by applicant): The regulation of cell volume is of critical importance to the CNS due to the restrictions of the skull. Brain swelling, which may occur in response to a lowering of plasma osmolarity or during cytotoxic edema, is associated with a number of clinical conditions, including congestive heart failure, hepatic encephalopathy, ischemic stroke, or head trauma. To counteract the increased volume, cells release Kv, CI-, and "non-perturbing" organic osmolytes, a major component of which is myo-inositol. Efflux of the osmolytes occurs via a volumesensitive organic anion channel (VSOAC), which primarily gates CI'. Although most attention has been focused on the role played by glia in the process of volume regulation, cultured neuronal cells have also been recently shown to exhibit similar properties. Moreover, recent results from this laboratory indicate that high concentrations of myo-inositol are present in some neuronal populations and that the polyol can be released in a volume-dependent manner. Although the electrophysiological and pharmacological characteristics of VSOAC have been well documented, relatively little is known of the cell signaling pathways that regulate osmolyte efflux through this channel. A central tenet of this proposal is that, in the face of hypoosmotic challenge, the capacity of neural cells to restore their volume via the efflux of inositol and other osmolytes can be regulated by extracellular agonists operating via phosphoinositide-linked receptors, such as the muscarinic cholinergic receptor. Thus we plan to examine the characteristics of myo-inositol efflux from human SH-SY5Y neuroblastoma cells under hypoosmotic conditions and evaluate the relationship between effiux of the polyol and changes in cell volume. In addition, we will test the hypothesis that activation of muscarinic cholinergic and other phosphoinositide-linked receptors leads to an increase in the effiux of inositol, and other osmolytes, from these cells. Furthermore, the possibility that individual osmolytes exit the cell via multiple VSOACs will be explored via a comparison of the effiux characteristics of inositol, taurine, and D-aspartate, all of which can be released from these cells. The ability to manipulate osmolyte effiux could be of potential benefit for a number of clinically relevant conditions. Accordingly, knowledge of the signal transduction pathways that regulate VSOAC is an essential prerequisite for the rational design of therapeutic agents.

Project Title: REGULATION OF 15N UREA ISOTOPOMERS PRODUCTION Principal Investigator & Institution: Nissim, Itzhak; Research Professor Pediatrics; Children's Hospital of Philadelphia 34Th St and Civic Ctr Blvd Philadelphia, Pa 191044399 Timing: Fiscal Year 2002; Project Start 01-APR-1999; Project End 29-FEB-2004 Summary: The biochemistry and physiology of hepatic ureagenesis has posed one of the more complex problems in metabolic regulation. The current proposal entails a comprehensive investigation of the mechanism(s) regulating hepatic ureagenesis in vivo or in liver perfusion, and delineates the determinants of mass isotopomers of [15N]urea production from 15N labeled precursor. We will address two primary hypotheses: (i) The preferential utilization of 5-15N of glutamine (Gln) for carbamoyl- phosphate (CP) synthesis may determine the rate of 15N incorporation into urea nitrogens depending upon acid base homeostasis and/or hormonal states; and (ii) Metabolites of arginine, i.e., nitric oxide (NO) and/or agmatine may have a key role in the synthesis of Nacetylglutamate (NAG), and therefore, the utilization of [5-15N]Gln for CP synthesis and [15N]urea production. An alternative hypothesis is that the partitioning of mitochondrial pyruvate metabolism between the pyruvate dehydrogenase (PDH) pathway (production of acetyl-CoA) and alanine formation via the mitochondrial alanine aminotransferase (MAAT) pathway, may determine the rate of NAG synthesis, and thereby, hepatic ureagenesis at various hormonal or acid-base states. We will use rats and/or liver perfusion as a model system and a perfusate which approximates the complex extracellular fluid taken up by the liver in vivo, with only one substrate labeled with 15N or 13C. We will determine the isotopic enrichment of the immediate nitrogenous precursor pools in urea synthesis, and identify primary site(s) of hormonal or acid-base regulation of [15N]urea mass isotopomers production from 15N labeled precursors by using Gas Chromatography-Mass Spectrometry (GC-MS) and/or Nuclear Magnetic Resonance (NMR). The data to be obtained will have considerable impact on our understanding of liver nitrogen metabolism in normal and disease states. We will provide a rigorous experimental framework for understanding the determinants of urea isotopomers production and delineate the mechanism(s) by which [H+] or hormones regulate hepatic nitrogen metabolism. A long term goal is to apply our experimental approach to human subjects in cases such as sepsis, hepatic encephalopathy and/or perturbed hormonal status, such as in diabetes.

Project Title: THE CNS AND CIRRHOSIS:PSYCHOBIOLOGICAL APPROACHES Principal Investigator & Institution: Stewart, Charmaine; Medicine; University of Pennsylvania 3451 Walnut Street Philadelphia, Pa 19104 Timing: Fiscal Year 2002; Project Start 01-SEP-2002; Project End 31-DEC-2002 Summary: (provided by applicant): Hepatic encephalopathy (HE) is one of the most common manifestations of decompensated cirrhosis. Approximately 70% of patients with cirrhosis also have subacute hepatic encephalopathy (SHE), as demonstrated on neuropsychological testing. The use of transjugular intrahepatic portosystemic shunts (TIPS), which acts as a side-to-side shunt, has become common to manage complications of cirrhosis. However, TIPS are associated with adverse effects, including worsening of existing HE or the precipitation of overt HE and liver failure. Liver transplantation has become the ideal management for patients who have decompensated liver disease. The
Studies
11
principal hypothesis of this proposal is that changes of HE and SHE can be determined by neuropsychological testing and changes in cerebral blood flow (CBF). The Specific Aims are the following: (1) Determine the changes in cognitive function in patients with cirrhosis; (2) Identify changes in CBF and neurotransmitter activity, as assessed by central benzodiazepine receptor binding and serotonin transporter binding after TIPS insertion; (3) Identify changes in CBF and neurotransmitter activity, as assessed by central benzodiazepine receptor binding and serotonin transporter binding after liver transplantation; and (4) Correlate the neuropsychological changes with cognitive function and central benzodiazepine receptor binding and serotonin transporter binding. These Specific Aims will be pursued in 60 subjects: group I will be 20 cirrhotics who will undergo TIPS; group II will be 20 cirrhotic patients who are scheduled to undergo liver transplantation; and group III will be 20 age and sex matched cirrhotic controls. All groups will be studied with a battery of neuropsychological tests and stimulated CBF, using 1502 labeled water, while half of groups I and II will be tested with 11C flumazenil PET or (11C)(+)McN5652 positron emission tomography (PET), in order to determine central benzodiazepine receptor binding and serotonin transporter binding, respectively, before and one month after undergoing TIPS or liver transplantation. The control group will be studied with 11C flumazenil PET or (11C)(+)McN5652 PET at baseline and 1 month, thereafter. In aggregate, these studies will provide a platform to elucidate cognitive and biological mechanisms underlying hepatic encephalopathy with the ultimate goal of enhancing diagnosis and management. Additionally, the proposed studies will be guided by a team of mentors and sponsors and supplemented by a didactic curriculum, all to lay the foundation for eventual independent clinical investigator status.

Project Title: THE ENCEPHALOPATHY
PERMEABILITY
TRANSITION
IN
HEPATIC
Principal Investigator & Institution: Norenberg, Michael D.; Professor; Pathology; University of Miami-Medical Box 248293 Coral Gables, Fl 33124 Timing: Fiscal Year 2003; Project Start 01-SEP-2003; Project End 31-JUL-2008 Summary: (provided by applicant): Hepatic encephalopathy (HE) is an important cause of morbidity and mortality in patients with severe liver failure. Acute HE associated with fulminant hepatic failure has an extremely poor prognosis and specific therapy is not available, short of an emergency liver transplantation. Although its pathogenesis remains poorly understood, ammonia is strongly implicated as a neurotoxin, and astrocytes appear to be the primary target of ammonia neurotoxicity. Additionally, altered bioenergetics and oxidative stress are thought to play a major role in this disorder. These facts led to a consideration of the involvement of mitochondrial permeability transition (MPT) as a factor in the pathogenesis of HE and ammonia neurotoxicity. The MPT is a Ca2+-dependent, cyclosporin A (CsA)-sensitive process due to the opening of a pore in the inner mitochondrial membrane leading to a collapse of ionic gradients and ultimately to mitochondrial dysfunction. We have recently shown that ammonia induced the MPT in cultured astrocytes. We intend to examine the role of the MPT in HE and hyperammonemia using ammonia-treated neural cell cultures and in vivo models of HE/hyperammonemia (HA). Our working hypothesis is that ammonia induces the MPT in astrocytes, culminating in mitochondrial failure and astroglial dysfunction. A corollary of this concept is that inhibition or interference in the development of the MPT in astrocytes may ameliorate CNS dysfunction in HE. The Specific Aims of this proposal are: 1) To identify the factors responsible for the
12
Hepatic Encephalopathy
ammonia-induced MPT in cultured neural cells. Our focus will be on agents implicated in the pathogenesis of HE/H that have also been shown to induce the MPT in other cells. Specifically, we will examine the role of Ca 2+, reactive oxygen species, nitric oxide, pH and glutamine. We will determine whether these factors are elevated in ammonia-treated cultures, and whether diminishing their production or blocking their actions reduces or abolishes the MPT. Additionally, we will examine possible sequential interrelationships among these factors. 2) To determine whether ammonia-induced abnormalities in astrocytes (morphological alterations, defects in neurotransmitter uptake, and cell swelling) are mediated by the MPT, we will investigate whether inhibitors of the MPT (CsA, bongkrekik acid) are capable of diminishing or blocking the deleterious effects of ammonia. 3) To investigate the involvement of mitochondrial dysfunction as a potential factor in MPT-mediated cell injury. We will determine the state of mitochondrial function after ammonia treatment, and then investigate whether improving energy metabolism will inhibit ammonia-induced cellular injury. 4) To clarify whether the MPT occurs in in vivo models of HE (thioacetarnide treatment) and hyperammonemia. We will also determine whether factors that inhibit the MPT in vitro (e.g., CsA, trifluoperazine) are also capable of doing so in vivo. Additionally, we will assess the ability of MPT blockers to improve the clinical, histopathologic, neurochemical abnormalities, and the extent of brain swelling observed in HE/HA. We believe that these studies will yield critical data bearing on the pathogenesis of HE, and may potentially aid in the development of novel therapeutic strategies for the treatment of this condition.

Project Title: TWO-DIMENSIONAL MR SPECTROSCOPIC CHARACTERIZATION OF HE Principal Investigator & Institution: Thomas, Michael A.; Associate Professor; Radiology; University of California Los Angeles 10920 Wilshire Blvd., Suite 1200 Los Angeles, Ca 90024 Timing: Fiscal Year 2003; Project Start 04-DEC-2002; Project End 30-NOV-2006 Summary: (provided by applicant): The major goals of this application are to evaluate a localized two-dimensional (2D) MR spectroscopic technique (MRS) and to detect cerebral metabolites unequivocally in hepatic encephalopathy (HE). Detection of early changes is very critical in the diagnosis of HE. Localized MR Spectroscopy is a major biochemical tool in characterizing noninvasively several metabolites in human tissues. Excellent one-dimensional (1D) MR spectra of HE and other pathologies have been reported with promising results. However, spectral overlap of various metabolites has been a major concern with the conventional 1D MRS. Spectral analysis of certain metabolites, namely glutamate, glutamine, GABA, myo-inositol, aspartate, glutathione, and the aspartyl groups of NAA and NAAG, has been complicated by severe overlap at 1.5T. 2D MRS seems well suited to address this problem of overlap. It has revolutionized the applications of NMR in biological macromolecules. Previous attempts by other researchers to implement the localized versions of the twodimensional MR techniques mainly used phantom solutions, although some results were reported from animal brains using a non-localized 2D technique. In addition to the major metabolites successfully assigned and analyzed so far with 1D MRS, more metabolites are yet to be detected and their respective roles in different pathologiesare yet to be explored using 2D MRS. A major hypothesis to be tested in this work is whether the changes of glutamine/glutamate, myo-inositol, aspartate, GABA and other cerebral metabolites can be detected using the localized 2D COSY more unambiguously

in HE than the conventional 1D MRS. Three specific goals of this project will be: 1) to acquire the single-voxel based 2D COSY spectra in the anterior cingulate and the basal ganglia regions of HE patients; 2) to record the global pallidal Mill changes in HE patients; 3) to perform the neuropsychiatric and neurocognitive assessment in HE patients, and to correlate the MR findings with the neuropsycho-logical, blood ammonia and liver function test results using multivariate regression analysis. AGE 1.5T MRI scanner with a bilateral surface "receive" coil (MRI Devices Corp.) in combination with a body rf "transmit" coil will be used to achieve improved signal detection. Minimal spectral overlap leading to less ambiguous assignment and better quantitation of glutamate/glutamine, GABA, myo-inositol, threonine, glucose, taurine and glutathione, will be a major outcome of this work.

With PubMed Central, NCBI is taking the lead in preservation and maintenance of open access to electronic literature, just as NLM has done for decades with printed biomedical literature. PubMed Central aims to become a world-class library of the digital age. 5 The value of PubMed Central, in addition to its role as an archive, lies in the availability of data from diverse sources stored in a common format in a single repository. Many journals already have online publishing operations, and there is a growing tendency to publish material online only, to the exclusion of print. 6 PubMed was developed by the National Center for Biotechnology Information (NCBI) at the National Library of Medicine (NLM) at the National Institutes of Health (NIH). The PubMed database was developed in conjunction with publishers of biomedical literature as a search tool for accessing literature citations and linking to full-text journal articles at Web sites of participating publishers. Publishers that participate in PubMed supply NLM with their citations electronically prior to or at the time of publication.

CHAPTER 2. NUTRITION AND HEPATIC ENCEPHALOPATHY Overview In this chapter, we will show you how to find studies dedicated specifically to nutrition and hepatic encephalopathy.
Finding Nutrition Studies on Hepatic Encephalopathy The National Institutes of Health’s Office of Dietary Supplements (ODS) offers a searchable bibliographic database called the IBIDS (International Bibliographic Information on Dietary Supplements; National Institutes of Health, Building 31, Room 1B29, 31 Center Drive, MSC 2086, Bethesda, Maryland 20892-2086, Tel: 301-435-2920, Fax: 301-480-1845, E-mail:
[email protected]). The IBIDS contains over 460,000 scientific citations and summaries about dietary supplements and nutrition as well as references to published international, scientific literature on dietary supplements such as vitamins, minerals, and botanicals.7 The IBIDS includes references and citations to both human and animal research studies. As a service of the ODS, access to the IBIDS database is available free of charge at the following Web address: http://ods.od.nih.gov/databases/ibids.html. After entering the search area, you have three choices: (1) IBIDS Consumer Database, (2) Full IBIDS Database, or (3) Peer Reviewed Citations Only.

CHAPTER 4. PATENTS ON HEPATIC ENCEPHALOPATHY Overview Patents can be physical innovations (e.g. chemicals, pharmaceuticals, medical equipment) or processes (e.g. treatments or diagnostic procedures). The United States Patent and Trademark Office defines a patent as a grant of a property right to the inventor, issued by the Patent and Trademark Office.8 Patents, therefore, are intellectual property. For the United States, the term of a new patent is 20 years from the date when the patent application was filed. If the inventor wishes to receive economic benefits, it is likely that the invention will become commercially available within 20 years of the initial filing. It is important to understand, therefore, that an inventor’s patent does not indicate that a product or service is or will be commercially available. The patent implies only that the inventor has “the right to exclude others from making, using, offering for sale, or selling” the invention in the United States. While this relates to U.S. patents, similar rules govern foreign patents. In this chapter, we show you how to locate information on patents and their inventors. If you find a patent that is particularly interesting to you, contact the inventor or the assignee for further information. IMPORTANT NOTE: When following the search strategy described below, you may discover non-medical patents that use the generic term “hepatic encephalopathy” (or a synonym) in their titles. To accurately reflect the results that you might find while conducting research on hepatic encephalopathy, we have not necessarily excluded non-medical patents in this bibliography.
Patents on Hepatic Encephalopathy By performing a patent search focusing on hepatic encephalopathy, you can obtain information such as the title of the invention, the names of the inventor(s), the assignee(s) or the company that owns or controls the patent, a short abstract that summarizes the patent, and a few excerpts from the description of the patent. The abstract of a patent tends to be more technical in nature, while the description is often written for the public. Full patent descriptions contain much more information than is presented here (e.g. claims, references, figures, diagrams, etc.). We will tell you how to obtain this information later in the chapter. 8Adapted

Hepatic Encephalopathy
The following is an example of the type of information that you can expect to obtain from a patent search on hepatic encephalopathy: •
Infusion solutions for the treatment of hepatic encephalopathy and method of using them Inventor(s): Kleinberger; Gunter (Vienna, AT) Assignee(s): Leopold & Co., Chem. Pharm. Fabrik Gesellschaft m. b. H. (Graz, AT) Patent Number: 4,259,353 Date filed: November 3, 1978 Abstract: Infusion solution for the treatment of human patients with heptic encephalopathy which consists essentially of a sterile aqueous solution of L-valine and has a pH-value of 7,4 to 7,5. This infusion solution when intravenously administered to patients in an amount of 20-85 mg/kg of body weight per hour influences hepatic encephalopathy in a very advantageous manner. Excerpt(s): It is known that in patients with hepatic encephalopathy, especially those in praecoma or coma hepaticum, the content of the branched amino acids valine, leucine and isoleucine is lower than normal and the content of the aromatic amino acids phenylalanine, tyrosine and tryptophane is higher than normal, see Fisher et al., Am. J. Surg, volume 127, page 40 (1974). Since such patients also require parenteral feeding, it has been proposed according to U.S. Pat. No. 3,950,529 to use nutrient solutions which contain at least the essential amino acids and in which very specific relationships between the branched-chain amino acids and the aromatic amino acids must be maintained, the content of tryptophane and of phenylalanine being limited in particular. By this means, excessive tryptophane transport to the brain is said to be prevented and it is said to be ensured that too high a phenylalanine content does not arise in the plasma. In the paper by E. Fisher et al., Surgery Vol. 80, No. 1, 77-91, 1976, it was finally pointed out that the degree of hepatic encephalopathy is decisively dependent on the factor of the concentration of the branched amino acids valine, leucine and isoleucine to that of the aromatic amino acids phenylalanine, tyrosine and tryptophane. It is suggested that the branched chain amino acids are competing with the aromatic amino acids for entry across the blood brain barrier and a higher dosage level of branched chain amino acids leads to a lower concentration of aromatic amino acids in the brain. It is presumed, that by this action the brain neurotransmitter profile, which is deranged in hepatic encephalopathy, can be improved. It is therefore pointed out that with nutrient solutions which are of a composition calculated so that it aims to normalize the amino acid level in the plasma, an amelioration of the encephalopathy is also achieved although the solutions also contain some amount of aromatic amino acids.

several years.) The following patent applications have been filed since December 2000 relating to hepatic encephalopathy: •
Dihydrofuran cyclic tanshinones used in treating hyperammonemia and hepatic encephalopathy Inventor(s): Bu, Xianzhang; (Guangzhan, CN), Gu, Lianquan; (Guangzhou, CN), Ma, Lin; (Guangzhan, CN) Correspondence: Banner & Witcoff; 1001 G Street N W; Suite 1100; Washington; DC; 20001; US Patent Application Number: 20040024056 Date filed: September 4, 2003 Abstract: The present invention relates to use of dihydrofuran cyclic tanshinones represented by the formula (I): 1wherein R.sub.1 is selected from a group consisting of -CH.sub.2CH.sub.2CH.sub.2C(CH.sub.3).sub.2--, --CHCHCHC(CH.sub.3)--, -CH.sub.2CH.sub.2CHC(CH.sub.3)--, or --CH.sub.2CH.sub.2CH.sub.2C(CH.sub.- 2)--, R.sub.2 is H or C.sub.1-C.sub.3 alkyl etc. or a pharmaceutical composition containing the same manufacturing medicine in preventing or treatment of hypermmonemia caused by chronic hepatitis and hepatocirrhosis, including hepatic encephalopathy and subclinical hepatic encephalopathy caused by hypermmonemia etc. Excerpt(s): The present invention relates to use of dihydrofuran cyclic tanshinones, especially Cryptotanshinone and Dihydortanshinone I for manufacturing medicine in preventing or treating hypermmonemia (over concentration of ammonia and phenethylamine in the blood) caused by chronic hepatitis and hepatocirrhosis etc., especially hepatic encephalopathy (HE) and subclinical hepatic encephalopathy (SHE) caused by hypermmonemia, and so on. Hypermmonemia is one of the major symptoms of chronic hepatitis and hepatocirrhosis. There are mainly two sources of ammonia production in the body: intestine and kidney. Most of the ammonia produced by them can be detoxicated through the ornithine cycle for synthesizing urea in the liver when its function is normal. However, the liver function of the chronic hepatitis and hepatocirrhosis patients is abnormal, and the ability of the liver to eliminate ammonia toxin is weakened, so there is increased amount of ammonia infiltrated into the blood, especially to the hepatocirrhosis patients for their greatly increased ammonia production caused by intestine congestion with portal vein diffluence formation and refluence blockage. Meanwhile, the kidney function of the chronic hepatitis and hepatocirrhosis patients is also impaired which also leads to apparently increased production of ammonia. Therefore, hypermmonemia is a symptom commonly shown by chronic hepatitis and hepatocirrhosis patients. Ammonia is a kind of basic toxic substance with poisoning effect to many major organs especially the brain. Long-term hypermmonemia is a major cause of aggravation and deterioration of chronic hepatitis and hepatocirrhosis, and initiation of hepatic encephalopathy (HE) and subclinical hepatic encephalopathy (SHE). Hepatic encephalopathy (HE) is a syndrome of central nervous system dysfunction based on metabolizing disturbance. Its main clinical manifestation is consciousness disorder, behavior disorder and coma (Pathology, edited by Li Yu-Lin, People's Health Press, 2000, p340-350). There are primarily two mechanisms for hepatic encephalopathy (HE). The first mechanism is the high concentrated blood ammonia caused by liver dysfunction permeating through bloodbrain barrier and entering into the brain tissue. The toxic effect of ammonia to brain tissue chiefly exists in its influence to the energy metabolism of brain cells, resulting in a decrease of the concentration of energy-rich phosphate compounds, some coenzymes and.alpha.-ketoglutarate. In normal situation, the liver can transform most of the
72
Hepatic Encephalopathy
ammonia produced in metabolism in the body into urea which is then removed form the kidney. In the situation of liver dysfunction, the ammonia eliminating ability will be weakened, thus the blood ammonia concentration increased. Moreover, at the time of alkalosis, the ionic type ammonium in the body will be transformed into molecular type ammonia, which also leads to a raise of blood ammonia concentration. The second mechanism is the action of the pseudo-neurotransmitter. The phenethylamine formed through decarboxylase effect by some amino acid such as phenylalanine can be decomposed and eliminated in the liver in normal situation, however, the blood phenethylamine concentration will rise and enter into the brain tissue through the blood-brain barrier, and converse into phenylethanol amine through the action of the enzyme in the neurocyte when the liver function is abnormal. Phenylethanol amine is a kind of pseudo-neurotransmitter with a similar structure to normal neurotransmitters such as dopamine, norepinephrine etc., but far weaker physiological functions. Phenylethanol amine can compete with normal neurotransmitter and so cause the dysfunction of cranial nerves. Web site: http://appft1.uspto.gov/netahtml/PTO/search-bool.html •
Remedy for hepatopathy Inventor(s): Chin, Masahiro; (Miyagi, JP), Doi, Hideyuki; (Miyagi, JP), Koga, Hiroshi; (Tokyo, JP), Komatsu, Hiromichi; (Shizuoka, JP), Satomi, Susumu; (Miyagi, JP) Correspondence: Browdy And Neimark, P.L.L.C.; 624 Ninth Street, NW; Suite 300; Washington; DC; 20001-5303; US Patent Application Number: 20040022827 Date filed: July 30, 2003 Abstract: Compositions that contain valine as an active ingredient but which are entirely free of other amino acids or substantially free of amino other acids as an active ingredient are used as drugs or foods for treating or ameliorating hepatic diseases, whereupon less side effects are caused than in the conventional regimens of pharmacotherapy and yet the compositions ameliorate, palliate or gain recovery from symptoms and abnormalities that are caused by such hepatic diseases, for example, fever, lassitude, loss of appetite, vomiting stomachache, ascites and pleural effusion, or complications of hepatic disease (not including hepatic encephalopathy). Excerpt(s): The present application is a continuation of U.S. Ser. No. 09/509,680, filed Mar. 30, 2000, which is the national stage under 35 U.S.C.371 of PCT/JP98/04495, filed Sep. 30, 1998. This invention relates to compositions for treating hepatic diseases or improving the hepatic function that are characterized by containing valine as an active ingredient and being substantially free of other amino acids as an active ingredient. More specifically, the invention relates to pharmaceutical or food compositions that contain valine as an active ingredient capable of treating or ameliorating hepatic diseases such as acute hepatitis, hepatic insufficiency, chronic hepatitis and cirrhosis but which are substantially free of other amino acids as an active ingredient. Various amino acid preparations are conventionally used against hepatic diseases such as hepatic insufficiency and cirrhosis. For example, amino acid preparations such as Aminoleban (registered trademark), Morihepamin (registered trademark), Aminoleban (registered trademark) EN, Hepan (registered trademark) ED and Livact (registered trademark) granule are used for such purposes as ameliorating hepatic encephalopathy and hypoalbuminemia that accompany hepatic diseases such as cirrhosis and hepatic insufficiency. In fact, however, these amino acid preparations are used not for direct
Patents 73
treatment or amelioration of the mentioned hepatic diseases but rather in anticipation of an improvement in impaired nutrition due to hepatic diseases, namely, for such purposes as improving nitrogen metabolism by correcting the imbalance in plasma amino acids and lowering the blood ammonia level. In addition, these preparations are mixtures of amino acids and single amino acids are little known to be capable of ameliorating the mentioned hepatic diseases. Referring to the official gazette of Examined Japanese Patent Publication No. 29446/1982, it is taught that an injection of Lvaline, when administered alone, is useful in the treatment of hepatic encephalopathy; however, hepatic encephalopathy is one of the complications of worsened hepatic disease and toxic substances such as ammonia that accumulate in blood impair the central nervous system to cause various neurotic symptoms; hence, hepatic encephalopathy is different from "hepatic disease" in the sense of term used in the present invention. What is more, the official gazette, supra, makes no suggestion that Lvaline is capable of direct treatment or amelioration of hepatic diseases per se. As a matter of fact, hepatic encephalopathy is currently treated with blood ammonia lowering agents such as lactulose and there have been reported no cases of using therapeutics for hepatic diseases in the treatment of hepatic encephalopathy, of which fact shows that the present invention is by no means easy to derive from the official gazette, supra.

Summary: This atlas is one in an 8-volume collection of images that pictorially displays the gastrointestinal tract, liver, biliary tree, and pancreas in health and disease, both in children and adults. This volume includes 14 chapters on the liver. Several chapters deal with the major manifestations of liver disease, providing reviews of jaundice, portal hypertension, hepatic encephalopathy, ascites, hepatorenal syndrome, and spontaneous bacterial peritonitis. The spectrum of manifestations of hepatitis (viral, autoimmune, and drug induced) is interwoven throughout the book. In addition, there is a comprehensive discussion of the problems attendant to the development of acute liver failure. The various causes of acute and chronic hepatitis are covered in depth and Hepatitis B and hepatitis C receive individual attention in separate chapters. The spectrum of drug-induced liver disease and the mechanisms by which drug-related liver injuries develop (and can be detected or prevented) is discussed. Liver disease caused by copper and iron receive special attention as do those disorders predominantly affecting the hepatic vasculature or the parnechyma in the form of abscesses or cysts. The volume describes tumors of the liver, once considered therapeutically hopeless, with emphasis on recently acquired information regarding the pathogenic roles of hepatitis B, hepatitis C, iron, and environmental toxins. The book includes a status report evaluating the roles of hepatic resection and transplantation as treatments for tumors. The last chapter of the book covers liver transplantation. The format of the atlas is visual images supported by relatively brief text. Tables, charts, diagrams, and photomicrographs are used extensively.

[email protected]. Website: www.wbsaunders.com. PRICE: $66.00 plus shipping and handling. ISBN: 0702018422. Summary: Wilson's disease, an inherited copper toxicosis, is a condition that affects the central nervous system and liver, and appears in childhood or early adulthood. Though the condition is rare, it is vital that the physician be aware of its clinical manifestations, since treatment can be very successful if instituted before irreversible organ damage has occurred. This book offers a comprehensive guide to the early diagnosis and treatment of Wilson's disease, using case studies to bring out the nuances of effective patient management. In addition, the author provides a review of the etiology and pathogenesis of the disease, plus practical guidance on new diagnostic tests and therapies. There is a genetic basis for the difference in the age of presentation. Patients with late (usually neurological) presentation have the H714X mutation; patients with early (usually hepatic) presentation have other, thus far unknown, mutations. Increase of free plasma copper, and not copper accumulation, is the central feature of Wilson's disease. High concentrations of copper in the liver and brain are a sign of copper detoxification by

Hepatic Encephalopathy
metallothionein. The neuropathological abnormalities in Wilson's disease and hepatic encephalopathy are similar at a microscopic level. Three clinical forms of neurological Wilson's disease can be distinguished: the dyskinetic, the pseudosclerotic, and the pseudoparkinsonian forms. The neuropsychiatric symptoms of Wilson's disease are those of subacute metabolic encephalopathy. The essential diagnostic indices of Wilson's disease are Kayser-Fleischer ring (in the eyes), low caeruloplasmin, high urinary copper excretion and high hepatic copper content. Pencillamine and zinc sulphate are both effective in the treatment of Wilson's disease. Because chelating (removal) agents may cause paradoxical deterioration, penicillamine should not be used as initial treatment. The author advocates starting treatment with zinc sulphate and to add penicillamine only if decoppering with zinc therapy alone is insufficient. The book includes a section of color plates, an extensive references list, and a subject index. 404 references.

Summary: Fulminant (acute) liver failure (FLF) is a relatively uncommon condition characterized by hepatocyte necrosis (liver tissue death) and disruption of liver function in proportion to the degree of liver cell death. With extensive liver cell death comes the development of clinically obvious hepatic encephalopathy, which defines the clinical condition of FLF. This chapter on the approach to patients with FLF is from a lengthy, two-volume textbook that integrates the various demands of science, technology, expanding information, good judgment, and common sense into the diagnosis and management of gastrointestinal patients. The chapter first discusses the definition, pathogenesis, and etiology of FLF. Thereafter, the authors discuss the clinical management of these patients, divided into pre-intensive care unit (ICU) and ICU management of patients with FLF. Subsequently, liver transplantation and developments in transplantation are discussed, as well as the available bioreactors for use in patients with FLF. Supportive therapy allows both functional and structural regeneration of the liver after FLF, without the development of chronic liver disease. However, in certain cases, the prognosis is grave and is greatly improved by emergency liver transplantation. 2 tables. 58 references.

Summary: Patients with liver (hepatic) failure frequently require drug therapy both for the primary hepatic disease and for other complicating conditions. The liver has a central role in drug metabolism and disposition and, consequently, impairment of hepatic function may have profound effects on drug handling. Since inappropriate drug administration may worsen hepatic failure or even precipitate serious complications, the administration of many drugs often needs to be modified radically in patients with liver failure. This chapter on hepatic failure is from a textbook that reviews the drug therapy

for gastrointestinal and liver diseases. The authors discuss general principles of prescribing for patients with liver failure, outline areas of importance in their supportive care, and examine practical therapeutic approaches to the treatment of hepatic encephalopathy, a frequent and important complication of hepatic failure. The chapter concludes with a drug list that summarizes mode of action, and other aspects of clinical pharmacology where appropriate, drug doses, common adverse affects, and drug interactions. 2 figures. 1 table. 79 references. •

Ascites is the accumulation of serous fluid in the abdominal cavity. Hepatic encephalopathy is a reversible state of impaired cognitive function or altered consciousness that occurs in patients with liver disease or portosystemic shunts. This chapter on portal hypertension, ascites, and hepatic encephalopathy is from an atlas of the liver, pancreas and gallbladder. The authors describe each condition, its diagnosis, and treatment strategies. The authors also briefly cover hepatorenal syndrome, an acute state of kidney failure resulting from intense constriction of the blood flow in the kidneys in otherwise normal kidneys; and spontaneous bacterial peritonitis.

Summary: This chapter on acute liver failure is from a comprehensive handbook in outline format that offers easy access to information on the full range of liver disorders and covers symptoms, signs, differential diagnoses, and treatments. The authors define acute liver failure as a syndrome of rapidly evolving hepatic synthetic dysfunction that is complicated by coagulopathy and, in advanced stages, hepatic encephalopathy. Acute liver failure can be divided into two subgroups: fulminant hepatic failure, with hepatic encephalopathy developing within 8 weeks of the onset of illness (or at least 2 weeks after the onset of jaundice); and subfulminant hepatic failure, with hepatic encephalopathy developing 8 weeks to 6 months after the onset of illness (or 2 weeks to 3 months after the onset of jaundice). Fuliminant hepatic failure is most often caused by acute hepatitis A, acute hepatitis B, or acetaminophen overdose, while subfulminant hepatic failure is more often caused by drug induced hepatotoxicity or unknown factors. The major complications of acute liver failure that require preventive measures or specific therapy include cerebral edema, coagulopathy, renal failure, hypoglycemia, and infection. Management of acute liver failure is directed toward aggressive supportive care in an intensive care unit and determination of whether liver transplantation is

Summary: This section on the nutrition management of the patient with hepatic (liver) failure is from a manual that serves as a nutrition care guide for dietetics professionals, physicians, nurses, and other health professionals. The manual integrates current knowledge of nutrition, medical science, and food to set forth recommendations for healthy individuals and those for whom medical nutrition therapy (MNT) is indicated. The challenge of nutrition support during hepatic failure is to provide absorbable nutrients in sufficient quantity to promote hepatic regeneration (liver healing) while preventing or minimizing nutrient intolerance and hepatic encephalopathy. Nutrition support is indicated for the patient with advanced hepatic disease who cannot meet his or her nutritional needs through oral intake. The text outlines the purpose, use, modifications, and adequacy of the diet. The section also outlines the related physiology, noting problems with malabsorption and the changes in mental status that may accompany hepatic failure. The section provides guidelines for enteral support and parenteral support. 12 references. (AA-M).

You will need to limit your search to “Videorecording” and “hepatic encephalopathy” using the “Detailed Search” option. Go directly to the following hyperlink: http://chid.nih.gov/detail/detail.html. To find video productions, use the drop boxes at the bottom of the search page where “You may refine your search by.” Select the dates and language you prefer, and the format option “Videorecording (videotape, videocassette, etc.).” Type “hepatic encephalopathy” (or synonyms) into the “For these words:” box. The following is a typical result when searching for video recordings on hepatic encephalopathy: •

[email protected]. PRICE: $89.00 plus shipping and handling. Summary: This health education videotape is designed to convince viewers of the liver damage caused by alcohol intake. Narrated by a registered dietitian, the program first briefly reviews the anatomy of the liver and then describes the liver's functions: making clotting factors, supporting the immune system, filtering out chemical and alcohol toxins (regardless of how they enter the body), maintaining glycogen (stored food energy), aiding digestion of fats, protein and carbohydrates, and making bile for digesting fats and accessing vitamins. The main factor in keeping the liver healthy is the avoidance of alcohol, but the program also discusses the importance of a healthy diet and regular exercise. The program then focuses on cirrhosis, a condition in which normal liver cells are replaced by scar tissue. The program offers mortality statistics and reviews the causes of cirrhosis, including hepatitis, genetic disease, drug effects, and alcohol (which causes 75 percent of cirrhosis cases). There are no adequate warning signs that become apparent before the liver has been damaged. The program discusses the consequences of cirrhosis, including malnutrition, hepatic encephalopathy (ammonia induced mental impairment), swollen abdomen (ascites), fatty liver (in which fat cells replace normal liver cells), and reduced ability to manage medications and toxins. A final section discusses liver failure and liver transplantation, emphasizing that there are never enough donor livers available and that people who have alcohol induced liver disease are often not acceptable transplant candidates. The program features interviews and scenes with patients and physicians.

CHAPTER 8. RESEARCHING MEDICATIONS Overview While a number of hard copy or CD-ROM resources are available for researching medications, a more flexible method is to use Internet-based databases. Broadly speaking, there are two sources of information on approved medications: public sources and private sources. We will emphasize free-to-use public sources.
U.S. Pharmacopeia Because of historical investments by various organizations and the emergence of the Internet, it has become rather simple to learn about the medications recommended for hepatic encephalopathy. One such source is the United States Pharmacopeia. In 1820, eleven physicians met in Washington, D.C. to establish the first compendium of standard drugs for the United States. They called this compendium the U.S. Pharmacopeia (USP). Today, the USP is a non-profit organization consisting of 800 volunteer scientists, eleven elected officials, and 400 representatives of state associations and colleges of medicine and pharmacy. The USP is located in Rockville, Maryland, and its home page is located at http://www.usp.org/. The USP currently provides standards for over 3,700 medications. The resulting USP DI Advice for the Patient can be accessed through the National Library of Medicine of the National Institutes of Health. The database is partially derived from lists of federally approved medications in the Food and Drug Administration’s (FDA) Drug Approvals database, located at http://www.fda.gov/cder/da/da.htm. While the FDA database is rather large and difficult to navigate, the Phamacopeia is both user-friendly and free to use. It covers more than 9,000 prescription and over-the-counter medications. To access this database, simply type the following hyperlink into your Web browser: http://www.nlm.nih.gov/medlineplus/druginformation.html. To view examples of a given medication (brand names, category, description, preparation, proper use, precautions, side effects, etc.), simply follow the hyperlinks indicated within the United States Pharmacopeia (USP). Below, we have compiled a list of medications associated with hepatic encephalopathy. If you would like more information on a particular medication, the provided hyperlinks will direct you to ample documentation (e.g. typical dosage, side effects, drug-interaction risks,

Commercial Databases In addition to the medications listed in the USP above, a number of commercial sites are available by subscription to physicians and their institutions. Or, you may be able to access these sources from your local medical library.
Mosby’s Drug Consult Mosby’s Drug Consult database (also available on CD-ROM and book format) covers 45,000 drug products including generics and international brands. It provides prescribing information, drug interactions, and patient information. Subscription information is available at the following hyperlink: http://www.mosbysdrugconsult.com/. PDRhealth The PDRhealth database is a free-to-use, drug information search engine that has been written for the public in layman’s terms. It contains FDA-approved drug information adapted from the Physicians’ Desk Reference (PDR) database. PDRhealth can be searched by brand name, generic name, or indication. It features multiple drug interactions reports. Search PDRhealth at http://www.pdrhealth.com/drug_info/index.html. Other Web Sites Drugs.com (www.drugs.com) reproduces the information in the Pharmacopeia as well as commercial information. You may also want to consider the Web site of the Medical Letter, Inc. (http://www.medletter.com/) which allows users to download articles on various drugs and therapeutics for a nominal fee.
Researching Orphan Drugs Although the list of orphan drugs is revised on a daily basis, you can quickly research orphan drugs that might be applicable to hepatic encephalopathy by using the database managed by the National Organization for Rare Disorders, Inc. (NORD), at http://www.rarediseases.org/. Scroll down the page, and on the left toolbar, click on “Orphan Drug Designation Database.” On this page (http://www.rarediseases.org/search/noddsearch.html), type “hepatic encephalopathy” (or synonyms) into the search box, and click “Submit Query.” When you receive your results, note that not all of the drugs may be relevant, as some may have been withdrawn from orphan status. Write down or print out the name of each drug and the relevant contact information. From there, visit the Pharmacopeia Web site and type the name of each orphan drug into the search box at http://www.nlm.nih.gov/medlineplus/druginformation.html. You may need to contact the sponsor or NORD for further information.

NORD conducts “early access programs for investigational new drugs (IND) under the Food and Drug Administration’s (FDA’s) approval ‘Treatment INDs’ programs which allow for a limited number of individuals to receive investigational drugs before FDA marketing approval.” If the orphan product about which you are seeking information is approved for marketing, information on side effects can be found on the product’s label. If the product is not approved, you may need to contact the sponsor. The following is a list of orphan drugs currently listed in the NORD Orphan Drug Designation Database for hepatic encephalopathy: •
Rifaximin (trade name: Normix) http://www.rarediseases.org/nord/search/nodd_full?code=907

103
Coffee Break: Tutorials for Biologists18 Coffee Break is a general healthcare site that takes a scientific view of the news and covers recent breakthroughs in biology that may one day assist physicians in developing treatments. Here you will find a collection of short reports on recent biological discoveries. Each report incorporates interactive tutorials that demonstrate how bioinformatics tools are used as a part of the research process. Currently, all Coffee Breaks are written by NCBI staff.19 Each report is about 400 words and is usually based on a discovery reported in one or more articles from recently published, peer-reviewed literature.20 This site has new articles every few weeks, so it can be considered an online magazine of sorts. It is intended for general background information. You can access the Coffee Break Web site at the following hyperlink: http://www.ncbi.nlm.nih.gov/Coffeebreak/.
Other Commercial Databases In addition to resources maintained by official agencies, other databases exist that are commercial ventures addressing medical professionals. Here are some examples that may interest you: •
CliniWeb International: Index and table of contents to selected clinical information on the Internet; see http://www.ohsu.edu/cliniweb/.
•
Medical World Search: Searches full text from thousands of selected medical sites on the Internet; see http://www.mwsearch.com/.
18 Adapted 19
from http://www.ncbi.nlm.nih.gov/Coffeebreak/Archive/FAQ.html.
The figure that accompanies each article is frequently supplied by an expert external to NCBI, in which case the source of the figure is cited. The result is an interactive tutorial that tells a biological story. 20 After a brief introduction that sets the work described into a broader context, the report focuses on how a molecular understanding can provide explanations of observed biology and lead to therapies for diseases. Each vignette is accompanied by a figure and hypertext links that lead to a series of pages that interactively show how NCBI tools and resources are used in the research process.
105
APPENDIX B. PATIENT RESOURCES Overview Official agencies, as well as federally funded institutions supported by national grants, frequently publish a variety of guidelines written with the patient in mind. These are typically called “Fact Sheets” or “Guidelines.” They can take the form of a brochure, information kit, pamphlet, or flyer. Often they are only a few pages in length. Since new guidelines on hepatic encephalopathy can appear at any moment and be published by a number of sources, the best approach to finding guidelines is to systematically scan the Internet-based services that post them.
Patient Guideline Sources The remainder of this chapter directs you to sources which either publish or can help you find additional guidelines on topics related to hepatic encephalopathy. Due to space limitations, these sources are listed in a concise manner. Do not hesitate to consult the following sources by either using the Internet hyperlink provided, or, in cases where the contact information is provided, contacting the publisher or author directly. The National Institutes of Health The NIH gateway to patients is located at http://health.nih.gov/. From this site, you can search across various sources and institutes, a number of which are summarized below. Topic Pages: MEDLINEplus The National Library of Medicine has created a vast and patient-oriented healthcare information portal called MEDLINEplus. Within this Internet-based system are “health topic pages” which list links to available materials relevant to hepatic encephalopathy. To access this system, log on to http://www.nlm.nih.gov/medlineplus/healthtopics.html. From there you can either search using the alphabetical index or browse by broad topic areas. Recently, MEDLINEplus listed the following when searched for “hepatic encephalopathy”:

Hepatic Encephalopathy
Cirrhosis http://www.nlm.nih.gov/medlineplus/cirrhosis.html Hepatitis http://www.nlm.nih.gov/medlineplus/hepatitis.html Hepatitis B http://www.nlm.nih.gov/medlineplus/hepatitisb.html Hepatitis C http://www.nlm.nih.gov/medlineplus/hepatitisc.html Laboratory Tests http://www.nlm.nih.gov/medlineplus/laboratorytests.html Liver Diseases http://www.nlm.nih.gov/medlineplus/liverdiseases.html Metabolic Disorders http://www.nlm.nih.gov/medlineplus/metabolicdisorders.html You may also choose to use the search utility provided by MEDLINEplus at the following Web address: http://www.nlm.nih.gov/medlineplus/. Simply type a keyword into the search box and click “Search.” This utility is similar to the NIH search utility, with the exception that it only includes materials that are linked within the MEDLINEplus system (mostly patient-oriented information). It also has the disadvantage of generating unstructured results. We recommend, therefore, that you use this method only if you have a very targeted search. The Combined Health Information Database (CHID) CHID Online is a reference tool that maintains a database directory of thousands of journal articles and patient education guidelines on hepatic encephalopathy. CHID offers summaries that describe the guidelines available, including contact information and pricing. CHID’s general Web site is http://chid.nih.gov/. To search this database, go to http://chid.nih.gov/detail/detail.html. In particular, you can use the advanced search options to look up pamphlets, reports, brochures, and information kits. The following was recently posted in this archive: •
Hepatic Encephalopathy Source: Toronto, Ontario: Canadian Liver Foundation. 200x. 3 p. Contact: Available from Canadian Liver Foundation. Suite 1500, 2235 Sheppard Avenue East, Toronto Ontario, M2J 5B5. (416) 491-3353 or (800) 563-5483. Fax (416) 491-4952. Email:

Summary: This fact sheet, from the Canadian Liver Foundation, reviews hepatic encephalothy (HE), a disorder of mental activity, neuromuscular function, and consciousness that occurs as a result of either chronic or acute liver failure (ALF). This complex neuropsychiatric syndrome is primarily caused by metabolic abnormalities. Written in question-and-answer format, the fact sheet covers the normal function of the liver, cirrhosis (scarring) of the liver, the different types of HE, symptoms of the different stages of HE, diagnostic approaches to HE, the pathogenesis of HE, and

treatment options. The author notes that the most important aspect of management of HE is the prompt recognition and correction of precipitating factors, when possible. These factors include kidney failure, use of sedatives or narcotics, gastrointestinal bleeding, hypokalemia or alkalosis, dietary protein increase, infection, constipation, and exacerbation of liver disease. The fact sheet concludes with the contact information for the Canadian Liver Foundation (www.liver.ca or 800-563-5483). The NIH Search Utility The NIH search utility allows you to search for documents on over 100 selected Web sites that comprise the NIH-WEB-SPACE. Each of these servers is “crawled” and indexed on an ongoing basis. Your search will produce a list of various documents, all of which will relate in some way to hepatic encephalopathy. The drawbacks of this approach are that the information is not organized by theme and that the references are often a mix of information for professionals and patients. Nevertheless, a large number of the listed Web sites provide useful background information. We can only recommend this route, therefore, for relatively rare or specific disorders, or when using highly targeted searches. To use the NIH search utility, visit the following Web page: http://search.nih.gov/index.html. Additional Web Sources A number of Web sites are available to the public that often link to government sites. These can also point you in the direction of essential information. The following is a representative sample: •

Finding Associations There are several Internet directories that provide lists of medical associations with information on or resources relating to hepatic encephalopathy. By consulting all of associations listed in this chapter, you will have nearly exhausted all sources for patient associations concerned with hepatic encephalopathy. The National Health Information Center (NHIC) The National Health Information Center (NHIC) offers a free referral service to help people find organizations that provide information about hepatic encephalopathy. For more
108
Hepatic Encephalopathy
information, see the NHIC’s Web site at http://www.health.gov/NHIC/ or contact an information specialist by calling 1-800-336-4797. Directory of Health Organizations The Directory of Health Organizations, provided by the National Library of Medicine Specialized Information Services, is a comprehensive source of information on associations. The Directory of Health Organizations database can be accessed via the Internet at http://www.sis.nlm.nih.gov/Dir/DirMain.html. It is composed of two parts: DIRLINE and Health Hotlines. The DIRLINE database comprises some 10,000 records of organizations, research centers, and government institutes and associations that primarily focus on health and biomedicine. To access DIRLINE directly, go to the following Web site: http://dirline.nlm.nih.gov/. Simply type in “hepatic encephalopathy” (or a synonym), and you will receive information on all relevant organizations listed in the database. Health Hotlines directs you to toll-free numbers to over 300 organizations. You can access this database directly at http://www.sis.nlm.nih.gov/hotlines/. On this page, you are given the option to search by keyword or by browsing the subject list. When you have received your search results, click on the name of the organization for its description and contact information. The Combined Health Information Database Another comprehensive source of information on healthcare associations is the Combined Health Information Database. Using the “Detailed Search” option, you will need to limit your search to “Organizations” and “hepatic encephalopathy”. Type the following hyperlink into your Web browser: http://chid.nih.gov/detail/detail.html. To find associations, use the drop boxes at the bottom of the search page where “You may refine your search by.” For publication date, select “All Years.” Then, select your preferred language and the format option “Organization Resource Sheet.” Type “hepatic encephalopathy” (or synonyms) into the “For these words:” box. You should check back periodically with this database since it is updated every three months. The National Organization for Rare Disorders, Inc. The National Organization for Rare Disorders, Inc. has prepared a Web site that provides, at no charge, lists of associations organized by health topic. You can access this database at the following Web site: http://www.rarediseases.org/search/orgsearch.html. Type “hepatic encephalopathy” (or a synonym) into the search box, and click “Submit Query.”

APPENDIX C. FINDING MEDICAL LIBRARIES Overview In this Appendix, we show you how to quickly find a medical library in your area.
Preparation Your local public library and medical libraries have interlibrary loan programs with the National Library of Medicine (NLM), one of the largest medical collections in the world. According to the NLM, most of the literature in the general and historical collections of the National Library of Medicine is available on interlibrary loan to any library. If you would like to access NLM medical literature, then visit a library in your area that can request the publications for you.21
Finding a Local Medical Library The quickest method to locate medical libraries is to use the Internet-based directory published by the National Network of Libraries of Medicine (NN/LM). This network includes 4626 members and affiliates that provide many services to librarians, health professionals, and the public. To find a library in your area, simply visit http://nnlm.gov/members/adv.html or call 1-800-338-7657.
Medical Libraries in the U.S. and Canada In addition to the NN/LM, the National Library of Medicine (NLM) lists a number of libraries with reference facilities that are open to the public. The following is the NLM’s list and includes hyperlinks to each library’s Web site. These Web pages can provide information on hours of operation and other restrictions. The list below is a small sample of

HEPATIC ENCEPHALOPATHY DICTIONARY The definitions below are derived from official public sources, including the National Institutes of Health [NIH] and the European Union [EU]. Abdomen: That portion of the body that lies between the thorax and the pelvis. [NIH] Abdominal: Having to do with the abdomen, which is the part of the body between the chest and the hips that contains the pancreas, stomach, intestines, liver, gallbladder, and other organs. [NIH] Abdominal Pain: Sensation of discomfort, distress, or agony in the abdominal region. [NIH] Abscess: A localized, circumscribed collection of pus. [NIH] Acceptor: A substance which, while normally not oxidized by oxygen or reduced by hydrogen, can be oxidized or reduced in presence of a substance which is itself undergoing oxidation or reduction. [NIH] Acetaminophen: Analgesic antipyretic derivative of acetanilide. It has weak antiinflammatory properties and is used as a common analgesic, but may cause liver, blood cell, and kidney damage. [NIH] Acetylcholine: A neurotransmitter. Acetylcholine in vertebrates is the major transmitter at neuromuscular junctions, autonomic ganglia, parasympathetic effector junctions, a subset of sympathetic effector junctions, and at many sites in the central nervous system. It is generally not used as an administered drug because it is broken down very rapidly by cholinesterases, but it is useful in some ophthalmological applications. [NIH] Acidosis: A pathologic condition resulting from accumulation of acid or depletion of the alkaline reserve (bicarbonate content) in the blood and body tissues, and characterized by an increase in hydrogen ion concentration. [EU] Acute renal: A condition in which the kidneys suddenly stop working. In most cases, kidneys can recover from almost complete loss of function. [NIH] Adaptability: Ability to develop some form of tolerance to conditions extremely different from those under which a living organism evolved. [NIH] Adenocarcinoma: A malignant epithelial tumor with a glandular organization. [NIH] Adenosine: A nucleoside that is composed of adenine and d-ribose. Adenosine or adenosine derivatives play many important biological roles in addition to being components of DNA and RNA. Adenosine itself is a neurotransmitter.
