A 36-year-old woman was admitted to our hospital because of general fatigue. The physical and laboratory findings on admission revealed splenomegaly, pancytopenia, hypocoagulopathy, liver hypofunction with a hepaplastin test of 55% and ICG Rmax of 0.6 mg/kg/min. Diagnostic imaging showed a hypoechoic mass 1.5 in diameter a low density area on the CT scan and a faint tumor stain on the AAG in the posterior inferior area of the liver. On a diagnosis of hepatocellular carcinoma with liver cirrhosis and hypersplenism, partial hepatectomy and splenectomy were performed. The resected hepatic specimen revealed a small liver cancer of 1.9 x 1.5 x 1.3 cm with liver cirrhosis. The specimen consisted of a firm rubbery mass. Macroscopically, the tumor appeared oval and was lobulated with a thin capsule. A fibrous scar was observed in the central area. Microscopically, malignant hepatocytes showed various shapes, ranging from polygonal to spindle form, with eosinophilic granular cytoplasm and were surrounded by abundant fibrous stroma. Orcein stain, revealed that these malignant hepatocytes contained many black granules of copper-binding protein. Immunoperoxidase staining for alpha 1-antitrypsin was also positive in the malignant hepatocytes. However, within this lamellar fibrous regions, there were many cords of tumor cells in which nucleoli were absent and abortive biliary differentiation was suggested. Consequently this tumor was diagnosed as an atypical fibrolamellar hepatocellular carcinoma. We think that this case is the 3rd case reported in Japan and the 2nd case in a Japanese person.

Seven women, mean age 47.7 years, with primary biliary cirrhosis (6 patients in the II-III stage and I patient in IV stage of the disease) were treated in the course of 16 months with ursodeoxycholic acid (Ursofalk) 500 mg daily. At the end of the 3-d month of treatment the itching had passed in 3 of the patients and in the remaining 4 patients it had substantially decreased. In all patients the subjective complaints, dyspeptic syndrome, appetite and sleep improved. The serum concentrations of bilirubin, copper and cholesterol started to decrease and the serum activity of the enzymes alkaline phosphatase, ALAT and ASAT also decreased. In one patient the treatment was discontinued in the 6-th month because of allergic reaction. After 16 month treatment in the 6 patients who completed the treatment the itching passed and the working capacity improved. The serum concentrations of bilirubin, cholesterol, copper and IgG significantly fell (p less than 0.01), the serum activity of alkaline phosphatase, gamma glutamyl transpeptidase, ALAT and ASAT fell near the upper normal range. The hepatomegaly, splenomegaly, McLagan's flocculation test, serum concentration of IgM and the titer of the specific antimitochondrial antibodies (M2) did not change in spite of the treatment. The results show the ursodeoxycholic acid as a perspective therapeutic means for primary biliary cirrhosis which lowers or overcomes the syndrome of intrahepatic cholestasis and limits the activity of the cirrhotic process in the liver. Ursodeoxycholic acid is well tolerated.

Serum copper, magnesium, zinc, calcium and ionized calcium (Ca++) concentrations were compared in 6 rabbits infected with Trypanosoma brucei brucei and 5 uninfected rabbits. There was a significant depletion of Mg and Zn and a significant increase in Cu from about day 10 of infection to the end. There was no change in plasma total calcium or free diffusible calcium. There was a development of kidney damage as shown clinically by proteinuria and urinary loss of magnesium and zinc, and histologically by the observation of hypercellularity in the glomeruli and tubular degeneration. Our findings thus indicate that trypanosomiasis causes kidney damage which may be responsible for the depletion of the cations seen in the study. Some of the clinical manifestations associated with African trypanosomiasis such as convulsions, anaemia, electrocardiographic changes and splenomegaly may therefore be related to these cation changes.

Bone marrow involvement was seen in 11 percent of patients with Hodgkin's Disease which was determined from pre-treatment biopsy specimens using established histopathologic criteria. Analysis of 32 evaluable patients with marrow involvement showed male preponderance with a peak in fourth decade of life. Twenty four cases (75%) had B-symptoms and 15 (46%) presented within six months of onset of symptoms. On categorizing for clinical staging, 21 (65%) belonged to stage III and IV. Hepatomegaly (greater than or equal to 2 cms) was present in seven cases (21%) and splenomegaly in 13 cases (40%). Mixed cellularity and lymphocytic depletion histopathologic subtypes showed the highest frequency of involvement (21 cases; 65%). Out of 28 cases ESR was raised in 27 cases (96%). Eighteen cases (56%) showed elevated serum alkaline phosphatase levels. Serum copper levels were determined in 14 cases, out of which 12 (85%) showed elevated levels. These parameters along with anemia (hemoglobin of 12 g/dl or less) in 26 cases (81%), correlated well with the disease activity. Only four cases had leukopenia at presentation pointing to no hindrance for aggressive chemotherapy. All cases received minimum of six courses of standard combination chemotherapy with or without local radiotherapy. Sixteen cases (50%) relapsed subsequently and were managed accordingly. A five year follow-up revealed a minimal 31 percent overall survival, and 18 percent of patients were disease free and well since the time of treatment.(ABSTRACT TRUNCATED AT 250 WORDS)

The ultrasonographic study of 33 patients with hepatolenticular degeneration showed the following main changes: disorders of the hepatic echotexture (29 cases), changes of the splenic dimensions (21), liver shrinkage (10), cholelithiasis (8), hepatomegaly and ascites (1). The disorders of liver echotexture exhibited different patterns, from slight to severe changes of the hepatic echogenicity, associated with anatomic distortions of the liver, such as alterations of outline and decrease of dimensions. Liver shrinkage was always accompanied by splenomegaly. The scarcity of hepatomegaly may be explained by the fact that the ultrasonography was performed after the onset of treatment with penicillamine, or by other factors still unknown, copper perhaps possessing a stronger fibrogenetic action than other hepatotoxic agents. Cholelithiasis was very frequent in females (6 of 13 patients), its incidence tending to increase with age. Regarding males there was no increase when the incidence was compared to the general population. The two sole males were young, an unusual finding in normal men.

Protein and lipid analyses were conducted on isolated erythrocyte and lymphocyte plasma membranes from 7-wk-old male C57BL copper-deficient and copper-supplemented mice to investigate mechanisms for the altered immunity that accompanies dietary copper deficiency. Beginning at parturition, dams were fed a diet low in copper (0.5 mg/kg) and the offspring were weaned to this diet. Half the dams and their respective offspring received supplemental copper (20 mg/L) in the drinking water (+Cu) and served as controls. Unsupplemented offspring (-Cu) had lower activity of cuproenzymes serum ceruloplasmin, spleen and thymus cytochrome-c oxidase and copper, zinc-superoxide dismutase. The -Cu mice exhibited anemia, splenomegaly and thymic atrophy. Based on the marker enzyme alkaline phosphodiesterase I (APDE-I), lymphocyte plasma membranes were enriched 7- to 10-fold for spleen and thymus, respectively, after discontinuous sucrose density centrifugation. The activity of APDE-I was higher in spleen and thymus samples from -Cu mice than from those of +Cu mice for both crude homogenates and purified plasma membranes. Proteins were fractionated by sodium dodecyl sulfate-polyacrylamide gel electrophoresis followed by silver staining. A yellow-appearing band, Mr 74,000, present in all splenic membrane samples from +Cu mice was not evident in the samples from -Cu mice. Fatty acid methyl esters (FAME) were quantified by gas chromatography. Compared to splenic membranes from +Cu mice, the samples from -Cu mice demonstrated significant changes in all FAME (lower 16:0, 18:0 and 20:3n-6 and higher 18:1n-9, 18:2n-6 and 20:4n-6), including a higher unsaturation index. FAME composition of erythrocyte ghosts from -Cu mice demonstrated similar changes.(ABSTRACT TRUNCATED AT 250 WORDS)

Wilson's disease is an autosomal recessive disease of copper metabolism which is widely recognized as a disease occurring clinically in children, adolescents, and young adults. Unrecognized and therefore untreated Wilson's disease in patients over age 40 is thought to occur either rarely or not at all. Two cases of Wilson's disease presenting at an age greater than 40 years are presented. The first is a 42-year-old Israeli women who presented with fulminant hepatic failure. The serologic and biochemical investigations obtained at the time of her fulminant hepatic failure included copper studies which suggested the diagnosis of Wilson's disease, which was confirmed by an examination of the native liver following successful orthotopic liver transplantation. The second case is that of a 56-year-old white male who presented to the hospital with a three-year history of neurological dysfunction, pancytopenia, and mild splenomegaly. A battery of serologic and biochemical investigations suggested a diagnosis of Wilson's disease. The diagnosis was confirmed by quantitative hepatic copper estimation and the demonstration of Wilson's disease in three of his siblings, all of whom were diagnosed after the proband case had been identified. This man and his siblings have been treated with d-penicillamine, with remarkable improvement in their neurologic and hepatic function. The proband is currently well 11 years after his diagnosis was established. These two cases demonstrate that a diagnosis of Wilson's disease should be considered as part of the differential diagnosis of individuals in the fourth and fifth decades of life who present with unexplained liver disease.

Apart from viruses, hepatotoxins, hereditary metabolic disorders, immunological factors and cholestasis may cause chronic hepatitis both clinically and histologically. As far as the etiology is concerned, a complete history can be very helpful. The clinical examination, however, is rarely diagnostic. Nevertheless, some clinical signs (e.g. ascites, splenomegaly, spider naevi) are suggestive of cirrhosis. The activities of gammaglutamyl transferase and ALT in the serum are augmented in most of the patients with chronic hepatitis independent of its etiology. Electrophoresis reveals disturbance of serum albumin and globulin ratios. "Basic' laboratory tests are supplemented by carefully selected additional investigations (e.g. immunological tests) according to the history and clinical data of the individual patient. Retrograde cholangiography is diagnostic in the majority of patients suffering from primary-sclerosing cholangitis. Liver histology, best obtained during laparoscopy, allows classification (and prognosis) of the underlying liver disease in many patients. Results of iron and copper determination in liver tissue are diagnostic in cases of congenital liver disease (hemochromatosis, M. Wilson).

Primary hemochromatosis is characterized by a specific pattern of clinical manifestations. It includes liver disease with hepatomegaly, glucose intolerance, e.g. diabetes, hyperpigmentation oft the skin, impotence/ amenorrhea, arthropathy, cardiomyopathy and fatigue. Laboratory investigation reveals significantly elevated serum ferritin and transferrin saturation with iron. The diagnosis is confirmed by liver biopsy and quantitative determination of elevated liver iron content. Wilson's disease represents a copper storage disease. Prominent clinical features are hepatomegaly and splenomegaly. Neurological alterations and detection of Kayser-Fleischer corneal rings are typical. In the acute initial phase the often young patients present with Coombs-negative hemolysis. Psychiatric alterations, cardiomyopathy, arthropathy, nephropathy, as well as thrombocytopenia and leucopenia are other clinical features. Laboratory parameters of Wilson's disease include low serum ceruloplasmin and serum copper. There is an elevated urinary copper excretion and elevated serum free copper concentration. The diagnosis is confirmed by liver biopsy with quantitative determination of an elevated liver copper content.

N-acetyl penicillamine (NAP), a derivative of penicillamine and copper chelator has been employed as a potential protector of host stress organ injury during Plasmodium berghei infection in mice. Intramuscular injection of NAP (60 mg kg-1 body wt for 10 days) to P. berghei mice was able to restrict the hepato- and splenomegaly. The mortality rate of infected mice was decreased by 50% by NAP. The decreased protein and lipid peroxidation and increased copper contents during P. berghei were almost normalized after NAP treatment. The increased levels of erythrocytic superoxide anion and lipid peroxides due to infection were almost normalized after NAP treatment.
