Liver cirrhosis is relatively rare in children as compared to adults; frequently it is diagnosed too late. Biliary cirrhosis of early childhood is often the result of neonatal cholestatic syndromes. Beyond infancy, cirrhosis as a consequence of chronic active autoimmune hepatitis or of Wilson's disease may be prevented, if causal therapy is begun in time. Hence paediatricians should exclude both diseases in all children with elevated transaminases and clinical features of a liver disorder.

Wilson's disease presenting as fulminant hepatic failure is a rare and poorly recognized disorder. When ophthalmic and neurologic signs are missing and liver biopsy cannot be performed the patients may not be diagnosed and treated specifically. An acute hemolysis only occasionally occurs in Wilson's disease but is considered a distinctive feature in the form of fulminant hepatitis. Two homozygous sisters suffering fatal Wilsonian fulminant hepatitis with hemolytic episodes are presented. Failure or delay in diagnosis seems to be responsible for high mortality in this form of Wilson's disease. Diagnostic value of familial history and laboratory results is discussed.

Penicillamine is known to be effective therapy for Wilson's disease. However, the clinical consequences of the abrupt and permanent withdrawal of penicillamine have not been investigated. We studied 11 patients who stopped their own treatment after having been treated successfully with penicillamine (1 to 2 g per day) for periods of 3 to 19 years. Eight died of hepatic decompensation or fulminant hepatitis after an average survival of only 2.6 years. In another 13 patients, penicillamine was discontinued by the physician because of serious adverse reactions. In these patients, penicillamine was replaced with trientine (1 to 1.5 g per day), a newer chelating agent. All but one of these patients (who was killed accidentally) are alive at this writing, from 2 to 15 years later. Our observations suggest that discontinuation of penicillamine in patients with Wilson's disease results in rapid clinical deterioration, which is often fatal. The replacement of penicillamine with trientine appears to prevent this adverse clinical course.

Although copper is believed to be hepatotoxic in Wilson's disease and Indian Childhood Cirrhosis (ICC), the rat shows only minimal hepatic damage on copper-loading. To investigate the possibility that copper deposition may potentiate the effects of a superimposed hepatitis, D-galactosamine (GalN) was given to copper-loaded and control rats. In the non-copper-dosed rats, GalN 0.85 g/kg i.p. produced elevated serum AST (3731 +/- 545 IU/l; normal 64.8 +/- 2.1), ALT (2090 +/- 190 IU/l; normal 18.0 +/- 0.7), and OCT (16.7 +/- 2.6 mmol/min/ml; normal 0.12 +/- 0), and liver cell necrosis with portal infiltration. In rats whose liver copper was elevated to 1298 +/- 169 micrograms/g (control 18.7 +/- 1.7) by oral copper supplementation, GalN produced much smaller increases in AST (825 +/- 122 IU/l), ALT (103 +/- 15 IU/l) and OCT (0.27 +/- 0.02 mmol/min/ml) and minimal histological damage. Viable bacterial cell counts from faecal homogenates showed that the anaerobically cultured bacteria were reduced on copper-dosing of rats. Therefore the protective effect of copper may be due to a decrease in gut-derived endotoxin acting on the liver, or to an impaired prostaglandin synthesis or perhaps to synthesis of acute phase reactants.

Consumption of the hepatotoxin arsenic is very common in certain geographical areas of India and occurs as a result of the intake of arsenic contaminated water, vegetables, adultered opium, ayurvedic and indigenous medicines, and "home made brew". Arsenic levels were estimated in livers obtained after autopsy from patients of idiopathic cirrhosis, alcoholic cirrhosis, Indian childhood cirrhosis, non-cirrhotic portal fibrosis, fulminant hepatitis and Wilson's disease. Significantly increased levels of arsenic were found in all diseased livers investigated when compared with values obtained from control groups. The study suggests that elevated levels of arsenic may be associated with liver disease.

The weights of the spleens of series of patients with various disorders of children dating from birth or early infancy and causing splenomegaly, with or without cirrhosis of the liver, were analyzed. The linear regression equation for spleen weight versus age in months for each disease was derived, and the rate constants from these equations were adjusted for the age range of the patients in each group. The original data of Coppoletta and Wolbach were used for normal values. The rates of splenic growth of appropriate entities for which the regression equation could be computed fell into three groups, with adjusted rate constants (growth of spleen in grams per month) of 6.53-6.95 (biliary atresia, thalassemia, and cirrhosis following neonatal hepatitis), 2.30-2.62 (cirrhosis of alpha-1-antitrypsin deficiency, infantile polycystic disease, and spherocytosis), and 1.06-1.11 (cystic fibrosis and idiopathic thrombocytopenic purpura). These classes of splenic growth rates are approximately 10, 3.7, and 1.6 times the normal growth rate (0.67 g/mo). Rate constants could not be computed for the categories cirrhosis following viral hepatitis and hemolytic anemia other than spherocytosis and sickle cell anemia, and the numbers of patients with splenic vein obstruction, cirrhosis with the cholestatic syndrome of parenteral alimentation, hypoplastic anemia with hemosiderosis, tyrosinemia, Byler's disease, congenital hepatic fibrosis, and Wilson's disease were too few for analysis. The significance of the finding of classes or "quantum groups" of splenic growth rates in disorders of children, dating from birth or early infancy and causing splenomegaly, is uncertain. Comparable data on adequate series of patients with other appropriate disorders will be necessary.

From 1974 through 1982, fulminant hepatitis was diagnosed in 34 patients at our institution. Of these patients, only two survived (survival rate, 6%). This syndrome was caused by viruses (B and non-B hepatitis and herpes simplex) in 23 patients, hepatotoxic drug in 6, Wilson's disease (hepatolenticular degeneration) in 3, and industrial poisons in 2. Most of the patients died within 10 days after the onset of encephalopathy. The poor prognosis in our group of patients was probably related to the preponderance of older patients and cases caused by non-B hepatitis virus. In our patients, the clinical course was complicated by renal failure, ascites, bleeding, sepsis, pancreatitis, and seizures. The major cause of death was hepatic failure.

Unit cell dimensions of mitochondrial crystals were determined by optical diffraction analysis of electron micrographs of human liver biopsy specimens. Identical unit cells were found in pathologic material obtained from six patients with Wilson's disease, from one patient with sickle-cell hepatitis, and from two normal subjects. These measurements led to the conclusion that the crystals observed in patients and in normal subjects were probably chemically identical. Furthermore, the relatively large size of the unit cell limits the choices for its constituents to phospholipid micelles or to relatively large protein molecules.

In the study the aspects noticed on hepatic biopsies by I.F. in HBsAg+ and HBsAg- chronic hepatitis and in some cases of hepatitis on dismetabolic basis in Wilson's disease are compared. Great differences occurred between HBsAg+, HBsAg- and the Hepatitis in Wilson disease. In fact in the first case reactivity is often present due to immunological phenomena (presence of IgG immunocomplexes and autoantibodies) while in Wilson's disease these aspects are not found confirming the hypothesis that in the latter case is a question of an exclusively toxic damage.

The clinical course of certain patients with Wilson's disease resembles that of patients with viral or drug-induced fulminant hepatitis lasting only few weeks from recognition of symptoms to severe hepatic insufficiency and death. The disease is complicated by hemolysis and is characterized by hypercupremia. Routine laboratory findings may underestimate the severity of the disease. These patients, as well as patients with decompensated Wilsonian cirrhosis who are not responding to therapy, should be considered as candidates for liver transplants.
