Non-alcoholic fatty liver disease, or NAFLD, represents a spectrum of pathologic liver histologic findings ranging from the simple accumulation of fat, known as steatosis, to nonalcoholic steatohepatitis and cirrhosis. It is estimated that NAFLD in all of its forms would have a 20% prevalence worldwide, but the evidence suggests a higher rate for developed countries, exceeding 30% for the US general population. Major risk factors for NAFLD, such as ageing, obesity and insulin resistance, are projected to increase in the following decades, causing the prevalence and relevance of NAFLD to rise in the future. In obese populations and type 2 diabetes patients, the prevalence of this disease exceeds 70%. NAFLD has been called the "silent epidemic" for its lack of symptoms, relatively complex diagnosis and its deleterious effects. The association between NAFLD with cardiovascular diseases, energy metabolism disorders and polycystic ovarian syndrome has promoted the inclusion of this liver pathology within the metabolic syndrome. From a biochemical point of view, current evidence suggests the existence of a bidirectional causal relationship between NAFLD and oxidative stress, where various alterations energy metabolism and important inflammatory components are involved. An abnormal glucose and fatty acid metabolism lead to glucotoxicity and lipotoxicity, respectively, which promote oxidative stress through different pathways. Oxidative stress induces the expression of pro-inflammatory mediators, including transcription factors and cytokines, which trigger an immune activation, a key step in the transition from simple steatosis to steatohepatitis. An early diagnosis and optimal therapy are essential for NAFLD treatment. First-line treatment of NAFLD focuses on lifestyle changes. Weight reduction through an increase in physical activity and/or nutritional management is considered safe and effective, but pharmacological management of common comorbidities such as hyperglycemia, dyslipidemias and hypertension are also essential. The key role of oxidative stress in NAFLD pathophysiology suggests that antioxidant interventions based in natural substances such as polyphenols would be effective. Recently, it was shown that the antioxidant properties of these compounds are beyond their free radical scavenging. This book presents an update of research advances contributing to a better understanding of relevant clinical models of NAFLD, particularly, the disorder in energy metabolism and the role of oxidative stress. It also highlights the clinical and pathophysiological association between NAFLD and the metabolic syndrome, and presents an overview of current diagnosis and treatment and the future avenues for the management of this disease.

This is the second edition of a very well received book devoted specifically to the treatment of liver tumors by radioembolization with 90Y microspheres.

The new edition has been fully updated to cover the most recent advances and includes additional chapters on regulations and emerging trends. Detailed information is provided on the full range of relevant topics, including hepatic vascular anatomy (including variants), dosimetry, assessment of tumor response, and the results achieved using radioembolization alone and in combination with other treatments in patients with primary or metastatic disease. Complications and side-effects are also fully discussed. This book will prove immensely valuable for both beginners and practitioners.

Hepatitis B virus (HBV) infection is a problem of global health importance and represents a significant cause of morbidity and mortality world-wide. HBV can be transmitted parenterally, sexually and perinatally. Despite progress on prophylaxis, diagnostic and treatment of HBV infection, it remains one of the major causes of chronic liver disease, cirrhosis or hepatocellular carcinoma. This book presents a compilation of current research including such topics as Hepatitis B and dialysis; Hepatitis B virus infection among middle school students in South Brazil; genotyping and management of chronic Hepatitis B; the risk assessment for Hepatitis B infection and its role in hepatocellular carcinoma; and silencing Hepatitis B virus replication with antiviral Pri-Mir shuttles generated from liver-specific Pol II promoters.

This book discusses in detail new aspects of the metabolic basis of important chronic liver diseases. Entities such as non-alcoholic fatty liver disease (fatty liver and Non-Alcoholic SteatoHepatitis -- NASH), diabeties in chronic hepetitis C, hemochromatosis, Wilson's disease, Gaucher disease, porphyria, as well as liver cirrhosis and its metabolic consequences will be discussed in detail. These clinical conditions are highly prevalent and affect millions of patients in the USA and world-wide. For example, non-alcoholic fatty liver disease is the most common cause of elevated liver enzymes in the general population. This field has been practically transformed over the last few years, with many new insights gained, regarding both pathogenesis and effective novel treatments.

Liver disease is a widespread and increasing problem throughout the world, however little is published on how different types and degrees of liver dysfunction affect the body's ability to handle medicines."Drugs and the Liver" is designed to assist practitioners in making pragmatic choices for their patients. It aims to: enable the practitioner to assess liver function using biochemical markers, other tests, signs, symptoms and disease knowledge; identify which pharmacokinetic and pharmacodynamic parameters of a drug are likely to be affected by different types of liver disease; and consider the impact of a drug's side effects on a patient with liver disease.This practical guide covers background information on liver function, the principles of drug use in liver disease and includes a section of worked examples of commonly asked questions. It will be invaluable to clinical pharmacists and anyone making medicine choices in patients with liver impairment.

The latest information on living with and treating liver disorders

"The Liver Disorders and Hepatitis Sourcebook, Revised Edition," gives you frank assessments of the latest therapies and drugs. It also provides advice on how you can navigate the day-to-day challenges of living with a liver disorder, and diet and nutrition guidelines, including the truth about the effectiveness of herbal remedies and liver-cleansing diets.

The liver is a large organ that sits in the right upper abdomen, just under the right lung. It is one of the body's most 'intelligent' organs in that it performs so many different functions at the same time. The liver makes proteins, eliminates waste material from the body, produces cholesterol, stores and releases glucose energy and metabolises many drugs used in medicine. It also produces bile that flows through bile ducts into the intestine where it helps to digest food. This organ also has the ability to regenerate itself if it is injured or partially removed. Cirrhosis is scarring of the liver that involves the formation of fibrous (scar) tissue associated with the destruction of the normal architecture of the organ. Many types of chronic injury to the liver can result in scar tissue. This scarring distorts the normal structure and re-growth of liver cells. The flow of blood through the liver from the intestine is blocked and the work done by the liver, such as processing drugs or producing proteins, is hindered. Until recently, the most common cause of cirrhosis of the liver in the United States was attributed to alcohol abuse. Because of the rapid increase of hepatitis C virus infection, hepatitis C has now taken over first place (26%), with alcohol abuse falling to second place, but only slightly behind at 21%. This outstanding new book elucidates new and important research results from throughout the world.

This book guides practitioners in the assessment of patients with a liver problem. The emphasis is on the role of macro- and microscopic pathology in elucidating pathogenesis as well as identifying confounding features of image findings that may lead to a more elaborate differential diagnosis. If appropriate, the role of light and electron microscopic examination, along with the role of specific stains and molecular techniques, is illustrated. In addition, the concept of each liver disease is summarized briefly and its up-to-data is provided, and unresolved problems in diagnosis, treatment, and pathogenesis are clearly described.The approach in this book is a practical one with a focus on the evaluation of illustrative cases, simultaneously demonstrating cross-sectional images (ultrasonography, computed tomography, magnetic resonance imaging, and angiography), pathological findings, and peritoneoscopic images. The diagnosis and therapy are summed up in helpful tables, and association of clinical manifestations with image analysis and pathological findings is shown to be important in differential diagnosis and treatment. With the authors comprising internationally renowned experts, this book will serve as a useful source of information for medical students, physicians, internists, hepatologists, gastroenterologists, radiologists, and pathologists worldwide.

* Hepatocellular carcinoma (HCC) used to be regarded as a rare disease. However, the increasing numbers of chronic HCC carriers in the U.S. and subsequent increased incidences of HCC seen in most large medical centers means that it is no longer an uncommon disease for gastroenterologists or oncologists to encounter and its incidence and epidemiology are changing. During this exciting time in the field of HCC basic science and clinical management, many changes are simultaneously occurring at multiple levels of our understanding and management of the disease. Suddenly, there are several new choices of therapy to offer patients. Hepatocellular Carcinoma, 3rd edition addresses this fast-changing disease and gives the reader a clearer understanding of the many mechanisms involved in carcinogenesis of the liver. This comprehensive and detailed review of how to diagnose and treat hepatocellular carcinoma is written by international leaders in the field, covering both clinical treatment choices and the basic science underlying HCC development. Updated and enhanced from the last edition in 2009, Hepatocellular Carcinoma, 3rd edition features 12 new chapters including discussion of molecular markers, molecular hepatocarcinogenesis, microenvironment, heterogeneity, the new and exciting contributions of immunotherapy, and updates on the major effective hepatitis therapies that will transform HCC incidence and perhaps also the therapy. This cutting-edge text is a vital resource and must-have for today's hepatologists and medical and surgical oncologists. "This is a well written text and should be a good reference book for those who see patients with HCC.." - Practical Gastroenterology "...a useful tool for both physicians and surgeons with a specific interest in the management of patients with HCC." - Digestive and Liver Disease
