Nine patients with acute liver failure due to Plasmodium falciparum liver injury admitted to the Rajgarhia Liver Unit of the All-India Institute of Medical Sciences during 1982-84 are presented. The liver was palpable in all the patients, and eight had splenomegaly. Investigations revealed mild to moderate abnormality in liver function tests. All were negative for the markers of acute infection due to hepatitis A and B viruses. Blood film examination showed P. falciparum alone in seven and along with P. vivax in the remaining two patients. Liver histology, which was identical in all eight patients where liver biopsy was done, showed centrizonal necrosis and hyperplastic Kupffer cells loaded with malarial pigment. All the patients recovered with specific anti-malarial and supportive treatment. Our observations suggest that malaria due to P. falciparum may present as jaundice and encephalopathy which stimulates acute hepatic failure due to fulminant hepatitis.

Lyme disease typically begins with a unique skin lesion, erythema chronicum migrans (ECM) (stage 1). Patients with this lesion may also have headache, meningeal irritation, mild encephalopathy, multiple annular secondary lesions, malar or urticarial rash, generalized lymphadenopathy and splenomegaly, migratory musculoskeletal pain, hepatitis, sore throat, non-productive cough, conjunctivitis, periorbital edema, or testicular swelling. After a few weeks to months (stage 2), about 15% of patients develop frank neurologic abnormalities, including meningitis, encephalitis, cranial neuritis (including bilateral facial palsy), motor or sensory radiculoneuritis, mononeuritis multiplex, or myelitis. At this time, about 8% of patients develop cardiac involvement--AV block, acute myopericarditis, cardiomegaly, or pancarditis. Throughout this stage, many patients continue to experience migratory musculoskeletal pain in joints, tendons, bursae, muscle, or bone. Months to years after disease onset (stage 3), about 60% of patients develop frank arthritis, which may be intermittent or chronic. Recently evidence suggests that Lyme disease may also be associated with chronic neurologic or skin involvement. Thus, Lyme disease occurs in stages with different clinical manifestations at each stage, but the course of the illness in each patient is highly variable.

Acute lead poisoning can present a difficult diagnostic dilemma, with symptoms that mimic those of hepatitis, nephritis, and encephalopathy. We report two cases in intravenous methamphetamine users who presented with abnormal liver function values, low hematocrit values, basophilic stippling of red blood cells, and elevated blood lead levels. Both patients excreted large amounts of lead in their urine after treatment with edetic acid, followed by resolution of their symptoms. Lead contamination was proved in one drug sample. Basophilic stippling of the red blood cells was the one key laboratory result that led to the definitive diagnosis in both cases.

We report 20 cases of alcoholic cirrhosis with superimposed episodes of acute viral hepatitis. Four had acute type B hepatitis and 16, presumed non A non B hepatitis. Before hepatitis, 17 patients had stopped drinking and only four had a complicated cirrhosis. Eighteen patients had received a blood transfusion within the 6 months before the occurrence of hepatitis (mean: 52 days). All patients developed jaundice, 7 encephalopathy, and 5 ascites. The ASAT/ALAT ratio was greater than 1 in 18 patients. Two patients died of hepatic failure. Follow-up was known in 17 of the 18 surviving patients: in all patients jaundice disappeared and transaminases returned to values less than 3 times the upper limits of normal. In our experience, the prognosis is good when viral hepatitis occurs in patients with non complicated alcoholic cirrhosis.

Antibodies to halothane-altered liver cell determinants (halothane antibodies) have previously been detected in serum of patients with fulminant hepatic failure after halothane anaesthesia. However, their diagnostic value has not been reported in patients with non-fulminant hepatitis. Sera from 39 patients who developed hepatitis following halothane anaesthesia between January 1983 and December 1985 were tested for antibodies to halothane-induced liver antigens using an ELISA; 22 of these patients had hepatitis without encephalopathy. Nineteen of the sera were from patients anaesthetized during 1985; four of the patients were aged 15 yr or less. All patients had undergone previous anaesthesia 17 days to 13 yr (median 3 yr) earlier. In 19 of the patients the final operation was a minor surgical procedure, lasting less than 45 min. In 13 patients a previous adverse reaction to halothane was documented in the case records. Twelve of the patients died. Halothane antibodies were detected in 12 of the 16 (75%) patients with hepatic encephalopathy and 16 of the 23 (70%) who did not develop encephalopathy, demonstrating that halothane antibodies are detectable in a wider spectrum of halothane-associated liver damage than previously appreciated.

A case of phenytoin-induced hepatitis with mononucleosis is reported, and syndromes associated with phenytoin hypersensitivity reactions are discussed. A 23-year-old black woman with a two-month history of seizure disorder was admitted to a hospital with nausea, vomiting, fever, lymphadenopathy, diffuse maculopapular rash, left-upper-quadrant tenderness, and hepatomegaly. She was receiving phenytoin sodium 300 mg/day; carbamazepine 200 mg four times daily had been discontinued four days before admission because of leukopenia. Phenytoin was discontinued after admission; however, phenytoin 1 g i.v. was given for a tonic-clonic seizure two days after admission, after which swelling of the face and legs and pruritus developed. Over the next few days, signs and symptoms of hepatotoxicity progressed, and she became comatose. Seizures were treated with diazepam. She began to recover after 10 days of supportive therapy and was discharged several weeks later on primidone therapy. Serious phenytoin hypersensitivity reactions may appear as dermatologic, lymphoid, or hepatic syndromes. Fever, rash, and lymphadenopathy often accompany hepatic injury. Encephalopathy and death may occur. Proposed mechanisms for phenytoin hypersensitivity include antigen-antibody reactions, alteration of lymphocyte function, and an enzyme abnormality causing the production of toxic metabolites. Treatment is supportive; phenobarbital and carbamazepine may be used with caution as alternate anticonvulsant therapy. The possibility of phenytoin hypersensitivity reactions should be considered when patients receiving phenytoin have unusual symptoms, particularly fever, rash, and lymphadenopathy.

Two cases of the Budd-Chiari syndrome are described in whom the diagnosis was finally confirmed at necropsy. The presentation was with encephalopathy, occurring within eight weeks of first symptoms and coming therefore within the definition of fulminant hepatic failure. In one, thought to have non-A, non-B hepatitis, encephalopathy progressed to grade 4 coma with death 12 days after presentation. In the other, mistakenly thought to have intra-abdominal malignancy, an exploratory laparotomy exacerbated the encephalopathy with death three weeks later. In neither case were non-invasive investigations, such as ultrasound and isotope scanning, carried out which might have facilitated an earlier diagnosis and consideration for orthotopic liver transplantation, probably the most appropriate form of therapy for these very severe cases.

Brain edema and intracranial hypertension are major complications of fulminant hepatic failure. We investigated the development of brain edema and monitored intracranial pressure in rabbits with toxic hepatitis induced by galactosamine. Using a gravimetric technique to assay small tissue samples, we found that brain water was increased in cortical grey matter, but not in subcortical, mesencephalic, and pontine white matter, or in the cerebellum. The proportion of water in cerebral grey matter in control animals was 80.96% +/- 0.49% with significant elevations to 81.96% +/- 0.47% and 82.95% +/- 1.49% in mild and severe encephalopathy, respectively. This corresponds to mean increases in tissue volume of 5.5% and 11.7%. The hippocampal grey matter also accumulated water in severe encephalopathy with a 30% increase in mean tissue volume. The regional increase in brain water was confirmed by the wet-dry weight method. Neither hypotension, hypoxia, nor severe hypoglycemia were present to account for the edema. Intracranial pressure was monitored continuously in unanesthetized rabbits via an intraventricular cannula as encephalopathy developed. The pressure was normal in the mild stage, but was intermittently elevated in animals with severe encephalopathy. The normal range of intracranial pressure was 2-9 mmHg and the range of peak values in galactosamine-treated rabbits was 18-55 mmHg. The regional differences in brain water accumulation suggest that cellular swelling and abnormalities in the movement of water across the blood-brain barrier may account for the brain edema in this model.

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.

Phenylalanine hydroxylation, tyrosine oxidation, and plasma appearance of phenylalanine and tyrosine were evaluated in a 49-yr-old woman with fulminant non-A, non-B hepatitis and encephalopathy using a continuous intravenous infusion of L-[ring-D5]phenylalanine and L-[U-14C]tyrosine. Despite marked elevations in plasma phenylalanine and tyrosine appearance and normal apparent albumin synthetic rates, phenylalanine clearance and hydroxylation to tyrosine were only 12% and 60%, respectively, of values observed in individuals with normal liver function. Three days after orthotopic liver transplantation, plasma phenylalanine and tyrosine appearances were not markedly changed. Phenylalanine clearance and conversion to tyrosine, however, were restored to normal. In addition, tyrosine oxidation and apparent albumin synthesis were increased. This case report represents the first in vivo demonstration of a selective diminution of enzyme function in an individual with fulminant liver disease. Liver replacement restored aromatic amino acid degradative capacity and increased albumin synthesis.
