33 patients with chronic renal failure were divided into two groups. Group I consisted of 8 non-dialysed patients without any clinical or biochemical sign of liver disturbance nor any iron supplementation. Group II consisted of 25 maintenance hemodialysis (MHD) patients treated from 2 to 13 years. 19 subjects had chronic B hepatitis. Total exogenous iron load parenteral iron and/or blood transfusions) was calculated. Body iron overload (hemosiderosis) was assessed by liver iron concentration (LIC) in needle biopsy specimens according to Barry's method (less than 200 microgram/100 mg dry weight) and serum ferritin levels (less than 360 ng/ml). 4 patients whose serum ferritin was increased with or without hepatic fibrosis and with or without any organ dysfunction due to hemochromatosis received i.v. infusions of desferrioxamine in doses of 2 g at each dialysis. Serum ferritin levels were correlated with LIC (p less than 0.001) and iron load (p less than 0.001). Hemosiderosis was noted in 16 MHD patients (group II) and correlated with iron load. Hemochromatosis was noted in 4 patients (group II). 4 hemodialysed patients with iron overload were treated by desferrioxamine from 6 to 18 months. During this therapy, body iron stores fell and organ dysfunction (heart failure, hepatic cytolysis, anaemia, diabetes mellitus improved. Long-term chelation therapy by desferrioxamine was effective and the chelated iron was readily removed by dialysis. These data show the importance of precise evaluation of iron stores in MHD patients.

Hepatic morphologic changes in seven patients in heart failure who were initially thought to have hepatitis are reported. In each instance, percutaneous liver biopsy or post mortem tissue examination disclosed a striking lesion involving all perivenular areas, with replacement of hepatocytes by erythrocytes. Four patients were in pure left-heart failure, while three were in biventricular failure. Upon treatment of the heart failure, the conditions of all patients improved clinically, and liver-function tests returned to normal or near normal. In two patients who later had refractory heart failure and died, there was no evidence of hepatic-vein thrombosis or occlusion post-mortem. A hypothesis is offered for the pathogenesis of this lesion, and its clinico-pathologic differential is discussed.

Ischemic hepatitis represents a condition in which an acute circulatory failure determines a striking elevation of both serum transaminases and total bilirubin and a prolongation of prothrombin time. Such impairment of liver function tests is due to a haemodynamic hepatocyte injury, showing focal centrilobular necrosis as the specific pathologic correlate. In this paper the authors describe four different cases of ischemic hepatitis, in which an acute derangement of liver function tests occurred as a consequence either of myocardial failure or of systemic venous congestion. Finally, the authors review all current international literature concerning the various clinical, pathologic and therapeutic features of ischemic hepatitis.

A 20 year-old white man was admitted with fever and weight loss since 60 days previous to his admission and cardiac failure (functional class IV). The heart was enlarged in the echocardiographic examination without valvular involvement. Liver biopsy showed granulomatous hepatitis with a necrosis focus. The patient was treated with a combination of venous dilators and digital. Serum agglutination test for Brucella showed a titer of 1/250, and complement fixation 1/40. Seven days later, agglutination titer was 1/4000. He was treated with rifampin and trimethoprimsulfametoxazol. He got better; fever disappeared, and the signs of cardiac failure improved. Brucellosic myocarditis is an uncommon complication of brucellosis in the absence of endocarditis. In our knowledge, this case would be the first reported in Argentina and the third in adult patients out of the five cases reported worldwide.

A 25 year-old woman diagnosed as acute myelocytic leukemia (M0) suffered a fourth relapse in February 1992 at which time she already had anthracycline-induced cardiac dysfunction. Although remission was induced by low dose cytosine arabinoside and etoposide combined with pirarubicin, she developed acute heart failure followed by extreme elevation of transaminases level and DIC. Abdominal echography and CT revealed small round lesions in the liver. We diagnosed this episode as ischemic hepatitis because of the following clinical findings; serological markers of virus hepatitis were negative, hypotension and reduced blood flow to the liver were seen, and both transaminases and LDH were markedly elevated. Dobutamin and oxygen inhalation were started, her liver function returned to almost normal levels 8 days later.

Eleven cases of hepatic injury attributed to the intake of flucloxacillin were reported to the Netherlands Center for Monitoring of Adverse Reactions to Drugs between 1982 and 1992. They concerned four men and seven women, with a mean age of 57 years, treated for 2-28 days with an oral dose varying from 1500-4000 mg per day. Symptoms mostly appeared 10 to 30 days after starting treatment with flucloxacillin. Biochemically, the pattern was compatible with cholestatic hepatitis in seven cases, with a mixed cholestatic-hepatocellular type of injury in one case, a hepatocellular pattern in two cases, and mild liver enzyme elevations in one patient. Two patients died, one due to fatal bleeding from the liver after biopsy, and the second patient to a combination of hepatic and cardiac failure. The other patients recovered, on average 72 days after peaking of serum aminotransferase values. Histology in seven cases showed cholestatic hepatitis in five, with cholangitis or cholangiolitis in four of these patients. In the other two patients, there was centrilobular cholestasis with extensive bridging fibrosis and portal-central bridging necrosis, respectively.

Acute alcohol ingestion can affect life expectancy and is directly responsible for 3,500 deaths per year. Acute lung diseases are mainly caused by pneumococci, Gram negative bacilli and anaerobic germs, and are often due to multiple microbes. In this case, evolution toward abscess can be feared. Septicaemia and enterobacterial peritonitis are frequently observed in cirrhotic patients. Ethanol, hypokaliemia and hypophosphoraemia also lead to rhabdomyolysis. Rhabdomyolysis can be complicated with acute renal failure and hyperkaliaemia. Alcoholic ketoacidosis and the hypoglycaemia favored by prolonged inadequate nutrition, are corrected by infusion of glucose solutions. Hyponatraemia can be complicated by convulsions and central pontine myelinolysis. Minor forms of alcoholic hepatitis remiss after stopping alcohol intoxication. The major forms can evolve toward fatal encephalopathy; treatment with corticosteroids improves the prognosis in severe hepatitis. The cardiac failure with lactic acidosis in shoshin beriberi rapidly evolves to collapsus; treatment is based on emergency administration of vitamin B1. Management of patients in acute alcohol episodes requires great vigilance. Careful clinical examination and biological tests should eliminate severe somatic complications before concluding to simple alcoholic intoxication.

Plasma DNA increases where cell death occurs in vivo. To investigate its significance in elderly patients, plasma DNA was assayed in 79 institutionalized patients over 68 years of age. The patients were divided into two groups: group I comprises 39 patients suffering from various acute or chronic illnesses; group II comprises 40 patients without chronic disease, and free of any clinical or biological symptoms of any infectious or inflammatory process. Plasma DNA was higher in group I than in group II (p < 0.0001) and in group II than in a control group of middle-aged subjects (p < 0.05). In group I, increase in plasma DNA concentration was found in various pathological situations associated with cell death phenomena, including infections, cancers with metastasis, hepatitis, irreversible cardiac failure, severe respiratory insufficiency and thrombophlebitis. Plasma DNA concentrations were not correlated with erythrocyte sedimentation rate, fibrinogen concentration, hemoglobin concentration or leukocyte count. In group I, as well as in the overall population, survival after 1 month was significantly reduced in patients with increased concentrations of plasma DNA. In conclusion, plasma DNA as a marker of cell death phenomena occurring in vivo, could be helpful for follow-up and management of elderly patients.

We studied four patients who presented a striking elevation of blood transaminases suggesting acute hepatitis. The post mortem histological examination of the liver revealed centrolobular necrosis that is commonly diagnosed as ischaemic hepatitis. The liver necrosis arose from heart failure which was worsened by an acute anaemia in one patient and by a severe hypoxemia, due to respiratory failure, in another. In three subjects there was evidence of disseminated intravascular coagulation that may be responsible for aggravating the condition of liver hypoxia. The authors also review the literature on the various aspects of ischaemic hepatitis.

Ischaemic hepatitis, a condition to be distinguished from cardiac liver or stasis cirrhosis, can occur as an acute episode in patients with advanced stage congestive heart failure. The mechanism is massive necrosis in the central lobules resulting from acute hypoxia when low cardiac output reduces oxygen supply further aggravating the underlying condition of congestion due to poor venous outflow. We report 4 cases which illustrate the difficulties in diagnosis and treatment. All four patients (age range 79-86 years) were seen in an emergency situation caused by an acute drop in cardiac output aggravating their underlying heart failure. Clinical signs included jaundice, oligouria, abdominal pain and cardiovascular shock. The first element suggesting the diagnosis of ischaemic hepatitis was a sudden and massive peak in transaminase levels (> 20 times normal) which rapidly returned to normal. Prothrombin and fibrinogen levels fell rapidly and functional renal failure was present in all cases. Viral serology was negative and no hepatotoxic drugs could be incriminated. Despite symptomatic intensive care one patient died on day 15 due to cardiovascular shock. Enzyme movements, together with the lack of evidence for another cause, is the key to diagnosis of acute ischaemic hepatitis which thus is often established after the emergency situation has been controlled. Initially, viral hepatitis or drug-induced hepatotoxicity may be suspected, especially if the episode of low cardiac output goes unrecognized. Cases with signs of encephalopathy may also be difficult to distinguish from fulminating hepatitis and would be the only indication for needle biopsy in this acute situation. Outcome is generally unfavourable with mortality at 6 months estimated at 50%.
