A case is described of permanent atrial paralysis in a 68 year old female with diabetes and cirrhosis of the liver. Absence of electrical atrial activity was expected on the standard electrocardiogram, and confirmed by intracavitary electrophysiological investigation which showed the ineffectiveness of stimulation of both the right atrium and the coronary sinus. Recording of the His potentials showed that the resultant rhythm was of supra-ventricular origin. The absence of mechanical atrial activity was confirmed radiographically, on the jugular venogram, on the apexogram, and on the tracings of right atrial and pulmonary capillary pressure. A search was made for muscular or neuromuscular dystrophy which has often been found in association with this arrhythmia, but none was found. There may be an etio-pathological relationship between carbohydrate metabolism and atrial paralysis, as certain authors have suggested.

Serum zinc concentrations are decreased in patients with a variety of clinical disorders including cirrhosis, nephrotic syndrome and renal insufficiency. Urinary zinc excretions are increased in the first two disease states. Symptoms of acute zinc deficiency (anorexia, dysfunction of smell and taste, and mental and cerebellar disturbances) and chronic zinc deficiency (growth retardation, anemia, testicular atrophy, and impaired wound healing) are common in these patients. It remains unresolved whether these disease states are indicative of true symptomatic or asymptomatic zinc deficiency or merely reflect a decrease in available zinc binding proteins. The low serum zinc concentrations and high urinary zinc excretions in patients with nephrotic syndrome do not appear to be due to loss of zinc bound to urinary proteins. Studies in dogs indicate increased serum and urine concentrations of certain amino acids(cysteine, histidine) greatly increase urinary zinc excretions. Studies are now underway to determine if the hyperzincuria and hypozincemia of cirrhosis, nephrotic syndrome and hyperalimentation can be explained by an increase in these urinary amino acids.

Derangements in glucose, amino acid and protein metabolism in patients with liver cirrhosis were examined with special reference to plasma levels of human growth hormone (HGH). Changes in blood glucose, IRI (immunoreactive insulin), HGH, FFA (free fatty acid) and plasma free amino acid levels were determined in controls and patients following either oral glucose load, protein feeding or intravenous arginine infusion. 1) In patients with liver cirrhosis, incidence of glucose intolerance after glucose tolerance test (GTT) was high and IRI levels were elevated in the fasting state as well as after glucose, protein or arginine loads. 2) Fasting levels of blood HGH were significantly higher in liver cirrhosis than in controls. GTT revealed that blood HGH levels decreased slightly during the rising phase of blood glucose, and conversely, increased during the falling phase of glucose (180 minutes after the glucose load) both in controls and in patients. In cirrhotic patients, marked increases in HGH levels were observed both 120 minutes after the protein load and 60 minutes after the arginine infusion. 3) Fasting levels of serum FFA were significantly higher in liver cirrhosis than in controls. Both controls and patients, however, showed a similar pattern of change in FFA levels following GTT or protein ingestion, i.e. a minimum value 120 minutes after the load and a gradual increase thereafter. 4) Fasting levels of plasma free amino acids were significantly higher in cirrhotic patients than in controls. After the glucose load, however, slight decrease was noted in some amino acid levels. All the amino acid levels examined were elevated following protein ingestion, particularly in cirrhotic patients. 5) A positive correlation was demonstrated in cirrhotic patients between total plasma free amino acids and maximal HGH responses following protein ingestion. Similar significant correlations were observed between the maximal HGH response and the plasma level of several amino acids such as His., Ser., Gly., Thr., Ala., and Ileu., respectively. 6) In cirrhotic patients, negative correlations were demonstrated between fasting levels of serum albumin and total plasma free amino acids or maximal HGH responses, respectively, after the protein ingestion. From these results it was inferred that derangements in the metabolism of protein and amino acids in cirrhotic patients may result in an increase in plasma free amino acid level which in turn stimulates HGH secretion. It was surmised that the HGH levels so elevated in the patients may cause FFA mobilization which in effect results in the glucose intolerance.

Amiodarone, a commonly used antiarrhythmic agent, has numerous adverse effects. The purpose of this case report is to highlight its hepatotoxicity, an unusual complication of long term amiodarone therapy. Our patient is a 76-year-old man with underlying ischaemic heart disease and recurrent ventricular tachycardia. Eleven months after commencing amiodarone, he developed asymptomatic raised aminotransferases which resolved following drug withdrawal. Amiodarone was then reintroduced and four years later, the patient developed hepatomegaly, worsening liver biochemistry and histopathological changes consistent with early cirrhosis. His symptoms improved following discontinuation of amiodarone. However, hepatomegaly and a low serum albumin still persist four years later.

A 42-year-old male was admitted with subarachnoidal hemorrhage. Dexamethasone 224 mg was used to reduce brain edema. His operation was successful without blood transfusion. No remarkable signs and symptoms were found except HBsAg positive and mild GPT elevation during his admission. He was discharged on the 33rd day. But 2 weeks later, he felt general fatigue and became worse day by day. He was re-admitted on the 75th day. Several therapies were given but he died of hepatic failure on the 85th day. The autopsy showed liver cirrhosis with massive necrosis. We believed that the steroid-withdrawal-phenomenon caused excessive immunological response and this process caused his hepatic failure leading to death.

We admitted a 60 year old patient with severe right hydrothorax. He was known to suffer from decompensated non-alcoholic cirrhosis. His invaliding dyspnea was only temporarily improved by repeated thoracocentesis, due to the very rapid refilling of the thorax from the ascites; until the development of a "tension hydrothorax" with dangerous mediastinal deviation. By insertion a peritoneo-venous shunt described by LeVeen the clinical picture was improved, and the patient no longe required further pleural aspiration. Six per cent of cases of ascites complicating hepatic cirrhosis may be associated with hydrothorax of the same origin. The diaphragm is normally perforated by a multitude of tiny virtual holes, closed by the peritoneum and the thoracic pleura. The high intra-abdominal pressure in ascites tears these fragile membranes, and allows the peritoneal fluid to overflow into the pleural cavity. Usually treated by fluid restriction and diuretics, when this condition becomes intractable or when a tension hydrothorax appears, interfering with respiratory function a LeVeen peritoneo-venous shunt should be inserted.

A 64-year-old man was admitted to our hospital because of possible liver cirrhosis. His serum cholinesterase was anomalously low with a delta pH of 0.1 (normal range; 0.8-1.1). His enzyme was more heat-labile than the normal controls. Km value of his enzyme for benzoylcholine was 1.1 x 10(-5) mol/l, while that for normal controls was 2.3 x 10(-6) mol/l. In addition, isozymic alteration of his enzyme was observed. Sequencing of the white blood cell DNA of the patient showed a point mutation at nucleotide 1093 (GGA to CGA), which changes codon 365 from glycine to arginine.

A 58-year-old man, with primary hemochromatosis, cirrhosis, and diabetes mellitus treated with insulin developed hepatoma. As the tumor grew, he lost his dependence on insulin therapy and experienced episodes of hypoglycemia. His response to infuse insulin was studied using the euglycemic clamp technique. Insulin was infused at rates of 1 and 10 mu/kg/min. The insulin dose response curve was shifted to the left and at plasma insulin levels of 72 microU/ml, steady-state glucose consumption was 9.6 mg/kg/min, 50% more than in normals, and nearly three times greater than that in other cirrhotics. The insulin clearance rate was 4417 m1/m2/min, almost five and six times more than in normals and cirrhotics, respectively. Basal hepatic glucose production was 3.6 mg/kg/min, two and three times higher than in normal and in cirrhotic subjects, respectively. The decrease in amino acid during hyperinsulinemia was more than 30% higher than in normal and other cirrhotics. IFG-I and II levels were not elevated in this patient. Increased insulin sensitivity and increased insulin clearance and serum amino acid decrease in response to insulin in vivo, suggest that insulin responsive tissues are at last partially responsible for tumor hypoglycemia. The increased glucose disposal rate probably accounted for the disappearance of the diabetes.

A 58-year-old male liver cirrhosis patient, who had a history of recurrent hepatic encephalopathy, was admitted to our hospital because of clouding of consciousness. He had an episode of recent head trauma. On admission, he was drowsy and exhibited flapping tremor, fetor hepaticus and ascites. Laboratory data showed an increase in blood ammonia level, and a decrease in peripheral thrombocytes, serum albumin and prothrombin value. A ratio of branched-chain to aromatic amino acids was reduced. Antibody against hepatitis C virus was positive. His electroencephalogram showed bilaterally large synchronous slow waves. He was treated with intravenous branched-chain amino acids, and recovered. Cranial computed tomography on day 9 demonstrated a crescent shaped area of low density in the right frontotempoparietal subdural region. He was diagnosed as chronic subdural hematoma, which was treated surgically. It has been suggested that chronic subdural hematomas develop as a complication of hemostatic deficiency due to liver cirrhosis.

Encephalopathy in liver disease may be unresponsive to protein restriction, lactulose, and neomycin. Zinc supplements have been reported to improve psychometric performance in liver cirrhosis, but the importance of zinc deficiency in overt hepatic encephalopathy has not yet been clearly established. A patient with severe recurrent hepatic encephalopathy was studied to determine the relation between her signs of encephalopathy and zinc deficiency. The study included a period in which zinc deficiency was artificially induced by oral histidine. An episode of overt encephalopathy occurred that was identical to earlier episodes and responded to oral zinc. The study showed an association between encephalopathy and zinc deficiency by successive zinc depletion and supplementation regimens. Long-term zinc supplementation improved severe recurrent hepatic encephalopathy and therefore the quality of life.
