Description : Over the past 10 years there has been a veritable explosion of knowledge in working in this area are fortunate to meet their bile acid research. Those colleagues from time to time at International Meetings which are often held in attractive parts of the world. The 7th International Symposium on bile acids 'Bile Acids in Gastroenterology' was no exception. It took place in Cortina d'Ampezzo in the heart of the Italian Dolomites, from 17th-20th March 1982. This meeting was organised by a Scientific Committee, with representatives from Italy, the United States and Great Britain, in collaboration with the Italian Society of Gastroenterology. The format of the meeting was somewhat different from that of previous years. In addition to the free communications (verbal and poster presentations) which characte rise many scientific meetings, there was also an Advanced Postgraduate Course on bile acids given by a distinguished international panel of experts. Their contributions form the basis for this timely volume which should be of interest both to basic scientists and to clinical investigators alike. The editors are indebted to Dr Gian Germano Giuliani, Gipharmex SpA, Milano, whose generous support made the meeting possible. They also thank Mr P. M. Lister, Managing Editor, MTP Press Limited and Mrs Veronica Cesari, Italian Society of Gastroenterology for help with the publication of these proceedings. R.

Description : This book contains the proceedings of the XIIIth International Bile Acid Meeting (Falk Symposium 80), an official satellite meeting of the World Congress of Gastroenterology, held in San Diego, California, U.S.A., September 30--October 2, 1994. It begins with presentations of major advances in bile acid chemistry, biology and pharmacology. The new structure proposed for the mixed micelles present in bile is reviewed, as are the properties of new synthetic analogues of bile acids. The mechanisms by which bile acids interact with cell membranes are discussed in order to provide insight into the hepatotoxic effects of bile acids in cholestatic liver disease. The book further shows the exciting progress in the molecular biology of bile acid transport by the hepatocyte and enterocyte, and concludes with a consensus on the use of ursodeoxycholic acid in cholestatic liver disease and as an adjunct to immunosuppressive therapy after liver transplantation, and to interferon therapy in chronic viral hepatitis.

Description : Bile acids occupy a central position in in the absorption, excretion and metab olism of lipids within the body. Our understanding of their unique properties has illuminated many biochemical and biophysical processes. Animals have evolved a unique system of preserving these important detergent-like molecules within the body and reusing them many times - the enterohepatic circulation. Disorders of the enterohepatic circulation contribute to a correspondingly wide range of diseases, and recent developments have centred in particular on cholesterol gallstone disease and bile acid diarrhoea. Successful manage ment of these diseases is increasingly based on an understanding of the physicochemical and biochemical properties of bile acids, and of their pathophysiological role in disease. Professor Alan Hofmann starts this book with an overview of the enterohepatic circulation of bile acids. The first section then discusses biliary lipid synthesis, transport and secretion by the liver and the solubilisation of cholesterol in the bile. The next section applies this knowledge to the pathogenesis of cholesterol gallstones. Separate chapters focus on defects in biliary lipid secretion, in cholesterol solubilisation and in gallbladder motility. The succeeding sections then review posssible approaches to gallstone prevention, and assess recent developments in non-surgical forms oftreatment. Two exciting new therapies that receive particular attention are contact dissolution therapy with methyl tert-butyl ether and extracorporeal shock wave lithotripsy. Further sections turn to the absorptive functions of bile acids in health.

Description : The last decade has seen tremendous developments in many fields of gastroenterology and hepatology. The aim of this series is to highlight some of these topics that deserve particular interest. Research in the field of viral hepatitis has been very intense and successful in recent years. The hepatitis B virus is one of the best explored at the current level of virology. Not only the nucleotid sequence of the viral DNA can be decoded, but also the amino acid compounds of its genetic products are known today. Since the techniques of molecular biology have increasingly found access to clinical laboratory use, hepatitis B virus infection can serve as an example for the importance of molecular biology in clinical hepa tology. Another example for the interdependence of basic science and clini cal medicine represents the research on bile acid metabolism. The investigation of bile acids has revealed new diagnostic approaches to hepatic and intestinal disorders. Commercial kits for the routine measurement of serum bile acids in clinical laboratories by enzymatic or radioimmunologic techniques are now available. The diagnostic value of these measurements in gastroenterology and hepatology shall be defined. Another aspect of bile acid research leads to new per spectives in the treatment of gallstone disease. The dissolution of cholesterol gallstones by chenodeoxycholic acid (therapy) may be quoted as the best example for the development of new phar macotherapeutic principles derived from basic bile acid research.

Description : This book is the proceedings of the Falk Workshop on `Bile Acids in Hepatobiliary Disease', which took place at the Royal Society of Medicine (RSM) in London, UK, on 29-30 March 1999, and was held in association with the Section of Measurement in Medicine at the RSM. The main interest in bile acid therapy has been recently in cholestatic liver disease. The proceedings of the workshop not only discusses this, but moves on to examine its possible use in alcoholic liver disease, and moves back to re-examine its role in biliary disease. Leading world experts attempt to define its mechanism of action, and the current role of other non-surgical treatments in biliary disease. The physiology and pathogenesis of cholestatic and alcoholic liver disease and cholesterol gallstone disease is also examined.

Description : The condition of prolonged obstructive jaundice with patent bile ducts was first described in 1851 by Addison and Gull of Guy's Hospital, London. The term primary biliary cirrhosis (PBC) was defined in 1950 by Ahrens and colleagues of the Rockefeller Institute, New York. The condition was considered rare but this changed in 1965 with the discovery of a definitive diagnostic serum mitochondrial antibody test and the recognition that a raised serum alkaline phosphatase value, often discovered incidentally, could be a diagnostic pointer. If the diagnosis is made earlier, the end stages are rarely reached as death is replaced by liver transplantation. On November 6th 1997, in Chicago, an International Faculty discussed in depth the clinical features, pathogenesis and treatment of PBC, no longer considered a rare disease. The course of PBC is long, but some 18 years after the discovery of a positive mitochondrial antibody test in a symptom free patient with normal serum biochemistry, 83% will have developed abnormal tests and 76% will be symptomatic. Identification of those who will progress rapidly is difficult. The serum antimitochondrial profile may be useful but this is a very specialist technique. Mathematical prognostic models are useful in therapeutic trials and in the selection and timing of patients for liver transplantation but have limited value in individual patients. An increasing serum bilirubin level remains the most important indicator of rapid progression. Its value however can be negated by the use of ursodeoxycholic acid which has a bilirubin-lowering effect.
