The role of tumor necrosis factor alpha (TNF alpha) in the immunopathological events induced by infection with lymphocytic choriomeningitis (LCM) virus (LCMV) was assessed by treatment of C57Bl/6 mice with a sheep antibody to murine TNF alpha antiserum to strongly interfere with anti-Listeria host defense. However, despite its effectiveness in Listeria infections in vivo, antibody to TNF alpha used at 6 x 10(4) neutralizing units per day subcutaneously had no detectable influence on the kinetics of maturation of antiviral cytotoxic T-cell activity, inflammatory processes, or clearance of virus. First, onset and severity of LCMV-induced hepatitis, as assessed by cytotoxic T-cell activity, viral titers in the liver, serum liver enzyme values, and histology, were not detectably affected by antibody to TNF alpha. Second, incidence of lethal LCM disease after intracerebral infection and the kinetics of the primary footpad swelling reaction observed after local foot inoculation were not altered by anti-TNF alpha antibody treatment. From the data presented we conclude that TNF alpha as assayed by in vivo therapy with a polyclonal anti-TNF alpha antibody plays no detectable role in the host reaction against LCMV.

A 10-week-old, black buck antelope calf, from the Mesker Park Zoo in Evansville, Indiana was found dead without observed signs of illness. Necropsy disclosed disseminated ecchymoses on the pericardium, diaphragm, intestines, and renal capsules and more extensive hemorrhage in the muscles of the hindquarters. There were numerous, 1 mm, pale foci on the capsular and cut surfaces of the liver and spleen which, on microscopic examination, were necrotic foci containing variable numbers of neutrophils and mononuclear leukocytes with numerous, short, Gram-positive, cocco-bacilli at the periphery. Listeria monocytogenes was isolated from the liver. Septicemia is the most common form of listeriosis in non-domestic ruminants. Listeriosis should be suspected when unexpected deaths are accompanied by multifocal necrotizing hepatitis and splenitis, myocarditis, and disseminated hemorrhage.

We report three cases of disseminated listeriosis that presented as acute hepatitis characterized by striking increase of liver function test values and fever. Peak serum transaminases (SGOT) for each of three patients were 5,380, 2,350, and 443 mu/ml respectively. The correct diagnosis was not suspected in any of the patients until blood and cerebrospinal fluid cultures obtained routinely in the course of evaluation for fever grew Listeria monocytogenes. When antibiotic therapy was instituted, serum transaminase values plummeted in two patients; these two were eventually cured of their infection. The third patient succumbed to his infection; postmortem examination showed miliary abscesses of the liver which revealed L. monocytogenes. Review of the literature for previous reports of hepatic involvement in adult patients with listeriosis shows that hepatitis is an unusual mode of presentation. However, since we observed these three cases over a one-year period, we suspect this may not be an uncommon occurrence.

We report the case of a 40 year-old woman, pregnant for 4 months, with acute hepatitis revealed by jaundice, fever and high serum aminotransferase levels. Infection by Listeria monocytogenes was demonstrated by blood cultures. The course of the disease was characterized by abortion and complete recovery of hepatitis within 4 weeks after antibiotic administration. This report shows that listeriosis can cause acute severe hepatitis.

Listeria is an uncommon cause of hepatitis in adults. We report the case of a liver transplant recipient who presented with a clinical picture of acute hepatitis, 8 months after grafting. Blood cultures yielded Listeria monocytogenes. The patient made a full clinical recovery after adequate antimicrobial therapy (ampicillin and gentamicin intravenously for 4 weeks). Hepatitis was attributed to the Listeria infection. We believe this is the first reported case of Listeria hepatitis in an organ transplant recipient.

Involvement of the liver in cases of Listeria monocytogenes infection is uncommon but has been manifested as solitary liver abscess, multiple liver abscesses, and hepatitis. We describe a 73-year-old diabetic woman who presented with a solitary liver abscess and prolonged fever, and we review the world literature on hepatic manifestations of L. monocytogenes infection. Patients presenting with solitary liver abscesses uniformly recovered with antimicrobial therapy and abscess drainage, whereas almost all patients presenting with multiple liver abscesses died.

Due to the urgency in choosing either clinical treatment or immediate surgical intervention, the study of the prolonged neonatal cholestasis involves two basic aims: the differential diagnosis between biliary atresia and neonatal hepatitis and the research into the associated etiological agents. So, in a prospective trial carried out in the 70's, 77 children with prolonged neonatal cholestasis were studied in order to establish the differential diagnosis between biliary atresia and neonatal hepatitis, followed by the evaluation of 108 children towards a pathogenesis of the prolonged neonatal cholestasis. The results of the differential diagnosis showed that within 18 items examined only 8 proved to be good biliary atresia indicators. They are as follows (in decreasing order): ductular proliferation (portal tracts), fibrosis (portal tracts), cholestasis (portal tracts), stools colour--acholia, hepatomegaly, canalicular cholestasis (lobule), infiltrate (portal tracts), giant cells (lobule). These eight items were then gathered in a sole indicator of great discriminative power, with a confidence level of 99%. The figures regarding the pathogenesis are: rubella virus 0%, herpes simplex virus 0%, listeriosis 0%, cytomegalovirus 2.2%, hepatitis B virus 2.4%, toxoplasmosis 2.8%, alpha-1-antitrypsin deficiency 13.1%, syphilis 21.1%, autoantibodies against the liver 58.4%. Such work thus revealed that those eight most important factors when differentiating biliary atresia from neonatal hepatitis remain as fundamental indicators and, when employed alongside other diagnostic methods, can help in the assembling of a multifactorial strategy less and less invasive and more precise. The pathogenic study, with its heavy dependency on time and place, has become more complete with the introduction of new diagnostic methods, evolving to the ideal progressive reduction of idiopathic processes.

Syncytial giant cell hepatitis in the neonatal period has been associated with many different etiologic agents and may present initially as cholestasis. Infectious causes are most common and include: (1 ) generalized bacterial sepsis, (2) viral agents, (3) toxoplasmosis, (4) syphilis, (5) listeriosis, and (6) tuberculosis. Viral hepatitis may be due to cytomegalovirus, rubella virus, herpes simplex, HHV-6, varicella, coxsackievirus, echovirus, reovirus 3, parvovirus B19, HIV, enteroviruses, paramyxovirus, and hepatitis A, B, or C (rare). Giant cell hepatitis may result in fulminant liver failure with massive hepatocyte necrosis and severe liver dysfunction leading to death, resolution with severely compromised liver function, or liver transplantation. The authors report a 6-week-old male who had an unremarkable perinatal period, became jaundiced after developing diarrhea, and subsequently developed liver dysfunction with massively increased liver enzymes and a coagulopathy. Open wedge and core liver biopsies were performed to determine if the patient should be listed for liver transplantation. Giant cell hepatitis with a significant mixed lymphocytic and neutrophilic infiltrate was present on both the wedge and core biopsies. The residual 60% of hepatocytes had ballooning degeneration and many possessed pyknotic nuclei. The hepatocytes were arranged in a pseudoacinar pattern. Electron microscopy showed paramyxoviral-like inclusions in the giant cells, characterized as large inclusions with fine filamentous, beaded substructures (18-20 nm). Paramyxoviridae are nonsegmented, negative-sense, single-stranded RNA viruses. This family is divided into the Paramyxovirinae subfamily containing respirovirus (Sendai virus, parainfluenza virus type 3), rubulavirus (mumps, parainfluenza virus type 2), and morbillivirus genera (measles); and Pneumovirinae subfamily (pneumovirus genus [respiratory syncytial virus]). Supportive care to determine if hepatic function resolves following the viral episode, liver transplantation with fulminant liver failure, and ongoing evaluation in those who recover to assess chronic liver disease are necessary. Ultrastructural evaluation may unmask the etiologic agent for hepatitis and direct therapy.

Listeria monocytogenes has long been known as a pathogen of immunocompromised hosts, including solid organ and bone marrow transplant recipients. Its principal manifestations include bacteremia and meningitis. Endocarditis due to Listeria is far less common and in general affects the left side of the heart. We here report an unusual case of Listeria tricuspid valve endocarditis and septic pulmonary emboli in a sulfa-intolerant liver transplant recipient with a history of relapsing cytomegalovirus (CMV) hepatitis and an indwelling Hickman catheter. The literature on Listeria endocarditis and infections in transplant recipients is reviewed. The possible relationship between susceptibility to Listeria infection and the discontinuation of trimethoprim-sulfamethoxazole prophylaxis is of interest.

Hepatitis due to Listeria monocytogenes is uncommon in adults. This report describes the first case observed in Senegal. The patient was a 73-year old man presenting listeria-related hepatitis presumably secondary to low-grade meningeal encephalitis. Treatment using ampicillin was unsuccessful and the patient died four days after hospitalization. The authors note that the incidence of adult listeriosis has risen constantly for the past twenty years in relation with alcohol abuse, cirrhosis, diabetes, kidney insufficiency, cancer, AIDS, and organ transplantation. However no predisposing factors were observed in the present case.
