Severe liver disease complicates pregnancy in only 0.1% of the cases. Viral hepatitis is the most common cause (40%). (Liver cirrhosis usually results in amenorrhea). Liver disease unique to pregnancy comprises "intrahepatic cholestasis of pregnancy" (Increased fetal risk), "acute fatty liver of pregnancy" (AFLP) and "HELLP-syndrome", both with high maternal and fetal risk when untreated. AFLP and HELLP-syndrome are diseases of the third trimester and show similar clinical signs of jaundice, coagulopathy and elevated liver enzymes. The immediate termination of pregnancy preferably by Caesarean section has been shown to improve both, maternal and fetal outcome. Imaging methods like ultrasound are invaluable in the differential diagnosis and detection of complications like subcapsular hematoma in the liver patients with HELLP-syndrome. Fulminant hepatic failure requires intensive care, liver transplantation is an additional therapeutic option. Recurrent AFLP has been reported recently.

Fulminant hepatic failure is caused by a variety of viruses, toxins, and metabolic derangements. The hepatitis C virus (HCV) causes indolent development of cirrhosis and has not been associated with fulminant hepatic failure. We report the first documented case of fulminant hepatitis C in the United States. The patient developed jaundice and stage IV encephalopathy. Initial laboratory evaluation did not reveal the etiology. The patient survived without liver transplantation. Three wk later he was found to have a positive HCV RNA and anti-HCV antibody seroconversion. He continued to improve with alpha-interferon treatment and has normal liver function and a negative HCV RNA 15 months later.

Fulminant hepatic failure (FHF) is a poorly understood condition in which total liver failure occurs and is thought to be caused by a variety of conditions including Reye's syndrome, hepatitis, drug overdoses, and vascular insufficiency. While this condition is an uncommon one, it carries with it a high fatality rate and must therefore be diagnosed as rapidly as possible. Six patients have been observed over a two-year period with biopsy and/or autopsy-confirmed FHF: one with acute hepatitis B-delta; three with histories of alcoholism, two of them with cirrhosis; one with acute tylenol overdose; and one with hepatic vascular insufficiency. All of these patients, except one, exhibited a rapid, fatal downhill course after onset of symptoms. In all of these patients, a consistent elevation was observed in serum levels of aspartate aminotransferase (AST) or serum glutamate oxaloacetate transaminase (SGOT) and alanine aminotransferase (ALT) or serum glutamate pyruvate transaminase (SGPT) such that the ratio of AST to ALT was significantly greater than 1 and in serum levels of ammonia. Other liver function tests were found to be abnormal but not in so consistent a pattern, although total protein and albumin were found to be significantly decreased in all of these patients. The stereotypical elevation of the transaminases with high AST-to-ALT ratios and the rise in ammonia appear to characterize this life-threatening illness most reliably.

Acute hepatic failure developed after 8-methoxypsoralen and ultraviolet irradiation for psoriasis in a patient with prior methotrexate-induced cirrhosis. Review of the literature and the temporal relationship between 8-methoxypsoralen and hepatic injury in our patient suggests it may be a direct hepatotoxin. In our report, submassive necrosis superimposed on cirrhosis appears to have produced hepatic failure.

Chronic liver diseases are potentially evolving clinical situations which, independently by the etiology, could proceed towards progressive liver structural and functional impairments. The only efficient treatment is orthotopic liver transplantation. Chronic liver diseases, and up to 40% of liver cirrhosis, are initially asymptomatic, but cirrhosis is the most frequent cause of death among non-neoplastic digestive diseases. Important elements complicating a decompensated liver cirrhosis are ascites, hepatic encephalopathy, digestive bleeding and jaundice. Acute liver failure (ALF) is the expression of a clinical state, that is common to many conditions sharing severe liver structural and functional impairments. In patients affected by decompensated liver cirrhosis, ALF could be triggered by several factors, while the death is caused by bleeding episodes, hepato-renal syndrome, spontaneous bacterial peritonitis or hepatocarcinoma. In patients affected by chronic liver diseases, the diagnosis of ALF is based on progressively increasing jaundice, encephalopathy and coagulopathy. Recent clinical trials have evaluated the efficacy of extrahepatic liver support systems, either artificial or bio-artificial, in treating episodes of ALF in chronic liver patients. The preliminary results indicate a potential use of such systems in blood detoxification, but they also showed limits in increasing patient survival.

Acute liver failure and haemolytic syndrome appeared quite suddenly as the first manifestations of Wilson disease (WD) in five of our patients previously regarded as healthy persons (although an interview showed that 2-4 weeks prior to the illness the patients complained of several non-specific symptoms, such as abdominal pain, headaches, fever, weakness or behavioural changes). All the patients were young women (17-23 years), none of them had any history of liver disease. They were admitted with icterus, nausea, vomiting and symptoms of increasing haemolysis. The diagnosis of WD was given as disturbed copper metabolism. After a short period of observation ascites and anasarca occurred, haemorrhagic diathesis and other symptoms of liver failure increased. Levels of clotting factors decreased rapidly. Despite treatment with D-penicillamine, plasmapheresis, and symptomatic drugs, three of the women died in irreversible liver coma, due to the unavailability of liver transplantation. The fourth woman was carried to the Transplantation Centre, due to aggravation of the symptoms of liver failure, where liver transplantation was performed. Histopathologically micronodular cirrhosis was shown in all these cases. The fifth patient survived having undergone the above treatment without liver transplantation. The main differences between the patient who survived and those who died or underwent transplantation were relatively higher activity of alkaline phosphatase (26 U/l vs. 10-20 U/l), slightly higher levels of clotting factors and prothrombin time, which never fall below 68% of the control (versus 14-44% in other patients). Only in the surviving patient was the Kayser-Fleischer ring present. In four of our patients we found family members who were carriers of WD.

Severe congestive heart failure is associated with two distinct forms of liver dysfunction: jaundice that is related to passive congestion and acute hepatocellular necrosis that is caused by impaired perfusion. Cardiac cirrhosis (fibrosis) may result from prolonged recurrent congestive heart failure. Ischemic hepatitis (shock liver) usually manifests as asymptomatic elevation of the serum aminotransferase levels after an episode of hypotension, although the clinical presentation may mimic that of acute viral hepatitis. In most cases, ischemic hepatitis is of little clinical consequence and is self-limited. Acute liver failure may occur in patients with preexisting cirrhosis, severe chronic heart failure, or sustained hepatic ischemia.

Recent advances in molecular biology have made possible the identification of genetic defects responsible for Wilson's disease, Indian childhood cirrhosis and copper toxicosis in Long Evans Cinnamon rats, toxic milk mice, and Bedlington terriers. The Wilson's disease gene is localized on human chromosome 13 and codes for ATP7B, a copper transporting P-type ATPase. A genetic defect similar to that of Wilson's disease occurs in Long Evans Cinnamon rats and toxic milk mice. Familial copper storage disorders in Bedlington and West Highland white terriers are associated with early subclinical disease, and copper accumulation with subsequent liver injury culminating in cirrhosis. The canine copper toxicosis locus in Bedlington terriers has been mapped to canine chromosome region CFA 10q26. Recently, a mutated MURR1 gene was discovered in Bedlington terriers affected with the disease. Idiopathic childhood cirrhosis is biochemically similar to copper toxicosis in Bedlington terriers, but clinically much more severe. Both conditions are characterized by the absence of neurologic damage and Kayser-Fleisher rings, and normal ceruloplasmin levels. A recent study added North Ronaldsay sheep to the list of promising animal models to study Indian childhood cirrhosis. Morphologic similarities between the two conditions include periportal to panlobular copper retention and liver changes varying from active hepatitis to panlobular pericellular fibrosis, and cirrhosis. Certain copper-associated disorders, such as chronic active hepatitis in Doberman pinschers and Skye terrier hepatitis are characterized by copper retention secondary to the underlying disease, thus resembling primary biliary cirrhosis in humans. Copper-associated liver disease has increasingly being recognized in Dalmatians. Copper-associated liver diseases in Dalmatians and Long Evans Cinnamom rats share many morphologic features. Fulminant hepatic failure in Dalmatians is characterized by high serum activities of alanine aminotransferase and aspartate aminotransferase, and severe necrosis of centrilobular areas (periacinar, zone 3) hepatocytes. Macrophages and surviving hepatocytes contain copper-positive material. Liver disease associated with periacinar copper accumulation has also been described in Siamese cats. Many questions regarding copper metabolism in mammals, genetic background, pathogenesis and treatment of copper-associated liver diseases remain to be answered. This review describes the similarities between the clinico-pathological features of spontaneous copper-associated diseases in humans and domestic animals.

The latest advances in hepatology were presented in oral and poster presentations. In order to cover the varying subspecialties, the sessions were divided into various sections including 'Acute Liver Failure and Artificial Liver Support', 'Biliary Tract and Immunologic Liver Diseases', 'Cellular and Molecular Biology', 'Clinical and Experimental Hepatobiliary Surgery', 'Hepatotoxicity and Cell Death', 'Transport and Biliary Physiology', 'Viral Hepatitis', 'Evaluation and Treatment of Biliary Disease', 'Necrosis/Apoptosis', 'Portal Hypertension', 'Blood Flow and Vascular Disorders of Cirrhosis', 'Liver Transplantation', 'Fibrogenesis', 'Hepatocellular Carcinoma', 'Metabolism and Genetic Disease', and 'Public Policy, Epidemiology and Decision Analysis'. Drug therapy focused on treatments for viral hepatitis, autoimmune hepatitis, primary biliary cirrhosis and primary sclerosing cholangitis, and recurrent viral disease following liver transplant. High dose interferon therapy or various combinations of interferon/ribavirin (ICN Pharmaceuticals Inc) therapy seem to offer the best current therapy for chronic HCV. PEGylated interferon (F Hoffmann-La Roche Ltd) offers hope for treatment and histologic improvement in patients with chronic HCV. Following liver transplantation, combination interferon/ribavirin therapy may also find success, but caution with new potent immunosuppressant monoclonal antibodies is advised. For HBV, intramuscular H-BIG (NABI) appears to be effective and less costly than iv H-BIG administration following liver transplantation. Percutaneous radiofrequency ablation may hold promise over conventional ethanol injection therapy for small hepatocellular carcinoma. Autoimmune hepatitis may respond to tacrolimus therapy whereas budesonide therapy did not provide any advantage to prednisone therapy. For primary biliary cirrhosis, eicosapentate and ursodeoxycholic acid may provide benefit to some patients while silymarin from milk thistle did not provide any additional benefit. In primary sclerosing cholangitis, high dose ursodeoxycholic acid may provide benefit. Ursodeoxycholic acid may also provide benefit for mothers with intrahepatic cholestasis of pregnancy by decreasing pruritus, lowering laboratory values and allowing deliveries to occur closer to term.

A Saudi family with Wilson's disease (hepatolenticular degeneration) is described. The index case presented with anicteric hepatitis and hydrops of the gallbladder. Neurological involvement appeared later. The diagnosis of Wilson's disease was based on the presence of Kayser-Fleischer rings, a low serum ceruloplasmin level, and an elevated urinary copper concentration. Histological examination of the liver biopsy specimen revealed active cirrhosis. Acute hepatic failure developed during D-penicillamine therapy. Continuation of the drug at a lower dose, along with other supporitve measures, was successful in reversing this. After three years of therapy, the index patient's neurological signs disappeared, and liver function and gallbladder size and function returned to normal. Family screening revealed that three other siblings have the disease, and all have been treated with D-penicillamine. The parents are related but are asymptomatic. An unusual feature of the index case was the presence of a distended nonfunctioning gallbladder that reverted to normal with decoppering. Although D-penicillamine treatment possibly precipitated the acute hepatic failure, paradoxically it was also successful in treating it.
