A standardized clinical, laboratory, and histological assessment was carried out on 85 patients with primary biliary cirrhosis within 1 year of developing symptoms. Presenting symptoms included pruritus (n = 30), jaundice (n = 9), variceal bleeding (n = 6), ascites (n = 5), fatigue (n = 4), and abdominal pain (n = 4). Ten patients had symptoms not immediately suggestive of hepatic etiology and a further 17 were asymptomatic, the diagnosis being made fortuitously. Eighty four percent were not incapacitated and 52 were anicteric. Less than half were pigmented, 22% had xanthoma, and only 12% were deeply jaundiced. In contrast, all had significant laboratory abnormalities with alkaline phosphatase activity greater than 400 IU/L in 60% and IgM greater than 2.5 g/L in 75%. Mitochondrial antibody was detectable in 83% with a titer greater than 1:160 in 70%. Cirrhosis was present in 24 patients, nine of whom were anicteric and a further 11 had fibrosis or scarring.

Cholestasis associated with Alagille syndrome may, in a few cases, be extremely severe and result in major impairment in the quality of life during early childhood and end up in cirrhosis eventually. We report the results of liver transplantation in 12 children with a severe hepatic form of Alagille syndrome. All children presented with cholestatic jaundice from birth, peculiar facies, stenosis of the peripheral pulmonary artery, and posterior embryotoxon; butterfly-like vertebrae were present in 9 children. At the time of transplantation (mean age 7 years 10 months) refractory pruritus was present in 9 children, xanthoma in 11, and height and weight retardation in 11. Total serum bilirubin ranged from 116 to 322 mumol/L and total serum cholesterol from 3.5 to 29 mmol/L. Systolic right ventricular pressure was moderately raised (36 to 48 mmHg) in 5 children; mean creatinine clearance was 99 ml/min/1.73 m2. Histologic examination of the removed livers showed cirrhosis, severe annular fibrosis, and moderate portal fibrosis in 4 children each. Follow-up in the 11 survivors has ranged from 14 months to 5 1/2 years. All lead normal lives. Pruritus and xanthomas disappeared. Increase in height was observed in 8 of the 10 survivors who had growth retardation prior to transplantation. School level is normal in 4 (median age at LT: 5 yr 9 mo) and below normal in 6 (median age at OLT: 9 yr 9 mo). Liver function tests are normal in 10 children. Mean creatinine clearance is 101 ml/min/1.73 m2. These results indicate that the quality of life can be considerably improved after liver transplantation in children with a severe hepatic form of Alagille syndrome and suggest that it could be carried out before these children attend elementary school.

Cholestatic liver disease is primarily caused by impaired bile production on the level of hepatocytes and cholangiocytes. Clinically cholestasis can be divided into intrahepatic and extrahepatic forms based on the presence or absence of dilated bile ducts (sonography). Intrahepatic cholestasis is most frequently caused by end stage liver cirrhosis followed by primary cholangiopathies and canalicular transport defects in hepatocytes. The causes of the most important cholangiopathies, such as Primary Biliary Cirrhosis (PBC) and Primary Sclerosing Cholangitis (PSC) are so far not known. Therefore, drug therapy of cholestatic liver disease focuses on the improvement of symptoms such as fatigue, pruritus, abdominal discomfort, jaundice, xanthoma, hypercholesterolemia, portal hypertension, blood count abnormalities, osteoporosis/osteomalacia, and the prevention of complications such as bile-duct strictures in PSC and development of cholangiocarcinoma. The first choice drug in the treatment of cholestatic liver disease of various causes is urosodeoxycholic acid (UDCA), that has been shown to decrease bile acid toxicity in general and prolong the transplant free survival of patients with PBC. If cholestasis persists cirrhosis of the liver is the major complication and liver transplantation may be the definitive treatment in advanced cases of cholestatic liver disease.

Alagille syndrome is characterized by a paucity of bile ducts in the liver. The syndrome is associated with some or all the features of chronic cholestasis, cardiac disease, skeletal abnormalities, ocular defects and a distinctive facial appearance. The most common finding is chronic cholestasis, which causes intractable pruritus, xanthoma, deficiency of certain metabolic nutrients and growth retardation. Cardiac abnormalities are the most common cause of death in these patients. It is unusual to see the clinical picture of hepatic failure resulting in cirrhosis and requiring transplantation, but liver transplantation is indicated in Alagille syndrome patients who have chronic cholestasis. If the disease is diagnosed in childhood, transplantation can improve significantly the patient's prognosis and the quality of life. In recent years, auxiliary liver transplantation has gained popularity for treating both acute and chronic liver disease. Heterotopic segmental liver transplantation is an alternative treatment modality for patients who do not require native liver removal. Individuals with Alagille syndrome are good candidates for this type of treatment. J Pediatr Surg 36:667-671.

The liver can be involved directly, by infiltration, and indirectly--by remote effects--in the histiocytoses of childhood. Langerhans cell disease, the most well recognized of these, infiltrates the liver directly but has a remarkable selectivity for the bile ducts. Early involvement is by Langerhans cell histiocytosis (LCH) infiltration leading to a sclerosing cholangitis and, eventually, biliary cirrhosis. Gamma glutamyl transpeptidase is a sensitive indicator of liver infiltration in a child with LCH. The indirect effects on the liver of LCH elsewhere in the body are mediated through an accompanying macrophage activation syndrome that is most likely responsible for hepatomegaly and hypoalbuminemia but without direct infiltration. These indirect effects are completely reversible. Juvenile xanthogranuloma/xanthoma disseminatum, a related dendritic cell disorder that can have systemic manifestations, has a strikingly different pattern, with a predominantly portal infiltrate spilling over into the adjacent lobule but sparing the biliary tree. The biology of the liver lesions is not clear but regression has been documented. Myeloproliferative disorders and myeloid leukemias can express CD1a and/or S100 protein, mimicking LCH but distinguished by their sinusoidal pattern. The primary macrophage histiocytoses such as the familial hemophagocytic syndromes can lead to severe liver damage. Although a portal lymphohistiocytic infiltrate is most characteristic, it is probably cytokine-mediated hepatocellular damage that can cause substantial functional impairment or even hepatic failure as a presenting feature. Liver involvement in other, more unusual histiocytic disorders, is also illustrated.

Ethanol is the most abused psychoactive substance. Accordingly to World Health Organization ethanol ranks among the top five risk factors for disease, disability and death (3.3 million/year) throughout the world. This manuscript highlights and critically analyses clinical and forensic signs related to hepatoxicity of ethanol that may lead to suspected of abuse. Namely, steatosis, jaundice, cirrhosis, hemorrhoids, esophageal varices caput medusae, ascites, petechiae, ecchymoses, splenomegaly, hemochromatosis, xanthelasma, nutritional deficiency, testicular atrophy, gynecomastia and dilated congestive cardiomyopathy are discussed and related to the toxic mechanism of ethanol.
