A common killer disease of the past, Indian childhood cirrhosis (ICC), which became preventable and treatable in the early 1990s, is now rare. ICC must be clearly distinguished in Indian children from other chronic liver disorders including Wilson disease. Grossly increased hepatic, urinary, and serum copper concentrations are characteristic of ICC. These increased concentrations are easily demonstrated histologically with orcein-rhodanine staining. Environmental ingestion of copper appears to be the most plausible explanation for ICC, as shown by feeding histories, the prevention of ICC is siblings and in the Pune district by a change in feeding vessels, and the dramatic reduction in incidence of ICC throughout India. The nature and role of a second factor in the causation of ICC remains unclear, although an inherited defect in copper metabolism is strongly suspected. ICC, however, does not appear to be a straightforward early onset of Wilson disease because ceruloplasmin is consistently normal and clinical and histologic recovery is maintained in the long term despite withdrawal of D-penicillamine therapy. Descriptions of an ICC-like illness in the West suggest that different mechanisms (environmental, genetic, or both) can lead to the same end-stage liver disease: copper-associated childhood cirrhosis. ICC probably represents a specific form of copper-associated childhood cirrhosis that requires high environmental copper ingestion for its full expression.

We describe a patient who had severe neurologic symptoms, psychiatric abnormalities, and secondary amenorrhea superimposed on a history of hemolytic anemia and micronodular cirrhosis attributed to hemochromatosis. The correct diagnosis of Wilson's disease was delayed until the appearance of Kayser-Fleischer rings and a low serum ceruloplasmin level. Appropriate treatment ameliorated symptoms, and maintenance therapy has been effective in retarding progression. It is essential to consider Wilson's disease in patients with unexplained hepatic, neurologic, and psychiatric dysfunction, because appropriate early medical treatment can prevent further organ damage and reduce the risk of permanent damage to the liver and brain.

End-stage liver disease secondary to cryptogenic cirrhosis is the indication for orthotopic liver transplantation (OLT) in 7% to 14% of recipients. However, there are no reports documenting the outcome of OLT for this indication. The aim of this study was to determine (1) survival and (2) the incidence of histological recurrence of cryptogenic cirrhosis after OLT. Between March 1985 and December 1994, 560 OLTs were performed at our institution. Of these, 39 transplants for cryptogenic cirrhosis were in patients who met the following criteria: antinuclear antibody < 1:40; negative anti-smooth muscle antibody, antimitochondrial antibody, polymerase chain reaction for hepatitis C virus, and hepatitis B surface antigen results; normal ceruloplasmin and alpha-1 antitrypsin phenotype; transferrin saturation < 65%; and liver biopsy specimen not suggestive of hemochromatosis or other known disorders. Histological recurrence was assessed with protocol liver biopsies in all patients who survived longer than 6 months. The mean age of cryptogenic recipients at the time of transplantation was significantly lower (40.6 years; range, 3 to 63 years) than that of noncryptogenic recipients (48.5 years; range, 1-70; P < .03). Median modified Child's-Pugh score was slightly higher for cryptogenic recipients at the time of transplantation (10.0 + 0.08 standard error of mean [SEM]), than for the noncryptogenic recipients (9.0 + 0.03 SEM; P < .02). Actuarial survival was 72% (+ 0.07 SEM) at 1 and 58% (+ 0.08 SEM) at 5 years for cryptogenic recipients compared with 89% at 1 and 80% at 5 years for noncryptogenic recipients. The difference in survival was significant (P < .001) at both 1 and 5 years. Among the 27 cryptogenic recipients surviving more than 6 months (mean follow-up, 5.5 years), 6 have persistent hepatitis histologically without apparent infectious, vascular, biliary, or drug origins. Four patients (15%) had chronic active hepatitis, and 2 (7%) had steatohepatitis. No cases of recurrent cryptogenic cirrhosis were seen. OLT for cryptogenic cirrhosis is associated with a poor outcome compared with other indications, hepatitis of uncertain origin occurred in 22% of cryptogenic recipients surviving longer than 6 months, and no evidence of recurrence of cryptogenic cirrhosis was seen thus far in follow-up.

Brazil has a young population and areas of endemic mansoni schistosomiasis where Wilson's disease might be easily misdiagnosed in patients erroneously classified as having either the hepatosplenic or the hepatointestinal form of the helminthiasis. Twenty five patients with the "hepatic form" of Wilson's disease (14 males and 11 females) were investigated in Belo Horizonte, MG; the mean age was 13.7 years (3 to 22). Nineteen had hepatomegaly (76%) and nine splenomegaly (36%). Twenty two (88%) had cirrhosis. The Kaiser-Fleisher ring was detected in fifteen (60%). Four (16%) had clear neurological abnormalities. Eleven (44%) had ascitis and/or jaundice. Ninety one point three per cent and 92% had low ceruloplasmin and copper serum levels respectively. Eighty four point two per cent showed an increased 24 hours urinary copper excretion; seven patients in whom hepatic copper was determined had increased values. Six out of nine had at least a ten fold increase in 24 hours urinary copper excretion following penicillamine use ("penicillamine test"). Three out of 19 patients (15.8%) had mansoni schistosoma ova in stools examination, a common prevalence in our population. Their biopsies showed inactive cirrhosis without schistosomiasis-associated alterations. At least fourteen patients (56%) could be misdiagnosed as having hepatointestinal or hepatosplenic schistosomisis when in fact they suffered from Wilson's disease with or without asymptomatic intestinal schistosomiasis, losing the chance of an early treatment. The follow-up time of 22 patients was 52 months (1 to 96); eight (36.3%) died, four from bleeding esphageal varices, three from terminal hepatic failure and one from fulminant liver failure. The majority of the patients, including those who died, had abandomned the use of penicillamine or had taken it irregularly, due mainly to its highly expensive cost. A 17 year old patient underwent a successful liver transplant in 1989.

Copper can induce acute and chronic intoxications in humans. Copper in tap water has caused a series of severe systemic diseases in Germany in recent years (copper induced liver cirrhosis). Besides cirrhosis, another type of disease with predominantly gastrointestinal symptoms has occurred which likewise appeared to be induced by copper in tap water. - In a retrospective investigation we looked for additional indications and proof that chronic copper poisoning has been the cause of the observed gastrointestinal diseases. All patients suffering from this type of disease had copper plumbing in their houses. - The patients (children and adults) suffered from nausea, vomiting, colic, and diarrhoea. In the group of infants, one refused formula milk (prepared with tap water) and the others suffered from persistent restlessness, unexplainable screaming (especially at night) and/or long lasting diaper rash. - We accept the diagnosis of chronic copper intoxication as the cause of the gastrointestinal symptoms when at least one of the following criteria were fulfilled: 1. first manifestation, remission and relapse of the disease depend on intake and a non-intake of water containing copper, respectively. 2. hypercupric state of the patients (i.e. pathological high concentrations of the non-ceruloplasmin-bound copper in serum and/or elevated copper levels in urine) 3. signs of systemic copper intoxication in the same patient 4. signs of systemic copper intoxication or hypercupric states in members of the patient s family or in his neighbourhood (non-relatives) - We found that the disease can even be caused by copper concentrations below the allowed concentration given by the German Guidelines for Drinking Water (Trinkwasserverordnung). - The data prove that copper in drinking water can cause gastrointestinal diseases and not only the better known systemic diseases (i.e. copper induced liver cirrhosis). Copper poisoning must be considered as a possible cause of chronic gastrointestinal diseases in those countries in which copper plumbing is common.

We describe a case of Wilson's disease with late psychiatric onset. Major depressive disorder was the first clinical manifestation at the age of 38 years. After pharmacotherapy with antidepressive agents, a manic episode was observed. Extrapyramidal hand tremor and micrography were the first neurological signs. Emotional lability occurred during worsening of extrapyramidal signs. Diagnosis was based on urinary and serum copper levels, ceruloplasmin serum level, Kayser-Fleischer ring, and liver biopsy that detected cirrhosis. Magnetic resonance imaging revealed basal ganglia hyperintensity on T1-weighted images, and hypodensity in the central part and hyperintensity in the peripheral part of the lentiform nucleus on T2-weighted images. Hyperintensity on T2-weighted images was also observed in the dorsal part of the midbrain. 123I-iodobenzamide single photon emission computed tomography (IBZM-SPECT) detected a normal distribution of the drug in the brain, with better signal in the right side and deficit of D2-dopaminergic receptors in the basal ganglia. Abnormal manganese erythrocyte level was observed. Treatment was based on penicillamine, zinc salts, low-copper diet, antidepressant agents, interpersonal psychotherapy and neurorehabilitation.

Orthotopic liver transplantation (OLT) has been applied to patients with Wilson's disease (WD) for correction of irreversible liver cirrhosis. However, the neurological outcome and the correlation between clinical manifestations and neuroimage findings after OLT remain uncertain. We present a WD patient who showed an improvement in both liver functions and neurological manifestations after OLT. Serum levels of ceruloplasmin and copper returned to normal rapidly after the operation. His ataxic gait was improved 5 months later and dysmetria and tremor disappeared 11 months later. The high signal intensities on T2-weighted brain magnetic resonance images regressed at bilateral thalami 5 months later and disappeared in bilateral thalami and red nuclei 16 months after OLT. We conclude that the neurological improvement could be expected in WD patients after OLT. The improvement was correlated with the MRI changes in red nuclei and bilateral thalami.

Wilson's disease is an autosomal recessive disorder of copper metabolism resulting from the absence or dysfunction of a copper transporting P-type ATPase encoded on chromosome 13. This ATPase is expressed in hepatocytes where it is localized to the trans-Golgi network and transports copper into the secretory pathway for incorporation into ceruloplasmin and excretion into the bile. Under physiologic circumstances, biliary excretion represents the sole mechanism for copper excretion, and thus affected individuals have progressive copper accumulation in the liver. When the capacity for hepatic storage is exceeded, cell death ensues with copper release into the plasma, hemolysis, and tissue deposition. Presentation in childhood may include chronic hepatitis, asymptomatic cirrhosis, or acute liver failure. In young adults, neuropsychiatric symptoms predominate and include dystonia, tremor, personality changes, and cognitive impairments secondary to copper accumulation in the central nervous system. The laboratory diagnosis of Wilson's disease is confirmed by decreased serum ceruloplasmin, increased urinary copper content, and elevated hepatic copper concentration. Molecular genetic analysis is complex as more than 100 unique mutations have been identified and most individuals are compound heterozygotes. Copper chelation with penicillamine is an effective therapy in most patients and hepatic transplantation is curative in individuals presenting with irreversible liver failure. Elucidation of the molecular genetic basis of Wilson's disease has permitted new insights into the mechanisms of cellular copper homeostasis.

A few patients with an affected CNS involving abnormalities in copper metabolism have been described that do not fit any known nosological entities such as Wilson's disease or Menkes' disease. Three sporadic patients (two men and one woman) were examined with involuntary movements and dysarthria associated with abnormal concentrations of serum copper, serum ceruloplasmin, and urinary copper excretion. The onset of neurological symptoms occurred at the age of 15 to 17 years. The common clinical symptoms were involuntary movements and dysarthria. The involuntary movements included dystonia in the neck, myoclonus in the shoulder, athetosis in the neck, and rapid orobuccal movements. The dysarthria consisted of unclear, slow, and stuttering speech. Two of the three patients did not have dementia. A cousin of the female patient had been diagnosed as having Wilson's disease and had died of liver cirrhosis. Laboratory findings showed a mild reduction in serum copper and ceruloplasmin concentrations, whereas urinary copper excretion was significantly reduced in all three patients. Two of the three patients showed a high signal intensity in the basal ganglia on T2 weighted brain MRI. In conclusion, the unique findings of involuntary movements, dysarthria, and abnormal serum copper and urinary copper concentrations suggest that the three patients may constitute a new clinical entity that is distinct from either Wilson's or Menkes disease.

We report the case of a patient with corticosteroid-responsive giant cell hepatitis associated with typical manifestations and changes of polyarteritis nodosa from the kidney and central nervous system. Initially, the patient presented with transient right hemiparesis, followed by spontaneous remission without any abnormalities on computed tomography scan, magnetic resonance imaging and cerebrospinal fluid examination. A few months later he was admitted to our clinic because of icterus, peripheral oedema and abdominal distension. He was found to have clinical signs of active cirrhosis. Serological tests for hepatitis B, C and HIV virus were negative. Serum ceruloplasmin. a1-AT and ferritin levels were within normal limits. Antinuclear antibodies were positive (1: 160). Liver biopsy showed micronodular cirrhosis with many eosinophils in the portal tracts and giant hepatocytes with multiple nucleoli in the lobule. Fulfilling the diagnostic criteria for autoimmune hepatitis, he was started on treatment with prednisolone and azathioprine, resulting in both clinical and biochemical responses. Four years later he presented with severe pain at the right costovertebral angle. Ultrasonography revealed a haematoma at the right kidney, and selective angiography of the abdominal aorta, renal arteries and hepatic artery documented microaneurysms in both kidney and liver arteries. Because of severe haemorrhage, right nephrectomy was performed. Histology of kidney specimen showed characteristic lesions of polyarteritis nodosa. Several months later, while on treatment with prednisolone and cyclophosphamide, the patient experienced a fatal episode of brain haemorrhage. An association between autoimmune hepatitis, polyarteritis nodosa and postinfantile giant cell hepatitis has not been reported previously.
