Echoviruses cause neonatal disease following intrauterine and intrapartum acquisition of the organism or by nosocomial infection. Dizygous twins apparently became infected following transplacental transmission of echovirus 11. At 5 days of age, both twins experienced poor feeding, lethargy and hypothermia, and evidence of coagulopathy and hepatitis. During the sixth week of illness, the convalescence of twin A was complicated by peritonitis and sepsis, and the infant died. Pathologic findings included scattered foci of dystrophic myocardial calcification, distortion of hepatic architecture with fibrous connective tissue surrounding regenerative nodules and large foci of dystrophic calcification, and adrenal hemorrhagic necrosis and calcification. Twin B recovered without sequelae. The disease in twin A was unusual because of the extensive myocardial involvement. Also of interest was the variability of disease in twins who presumably had received a similar inoculum of organism by the same route.

A total of 133 children aged between less than a month to 14 years presenting consecutively with hepatitis were prospectively studied over a 6-year period. Most cases were acute and presented at the icteric phase. The peak incidence was in very young infants whose illness had to be differentiated from congenital biliary tract obstruction. The older children exhibited the usual manifestations of lethargy, anorexia and tenderness over the liver area to varying degrees. There were 2 cases of chronic active hepatitis in children aged 13 and 14 years, one a female and the other a male. Their illness was controlled with steroid therapy. The serum biochemistry was characteristic in all cases. Serological tests revealed that about 55% of the children had antibody to hepatitis A virus but only 4% demonstrated HAV-specific IgM, while 15% had hepatitis B surface antigen (HBsAg) and 23% demonstrated antibody to core antigen (HBcAg). While most of the children with acute hepatitis made a full clinical and biochemical recovery, 2 have persistent HBs antigenaemia. There were 3 deaths in children who had fulminant hepatitis. Our results show that exposure to hepatitis A virus appears to be prevalent in Nigerian children and probably occurs quite early in life, and infections with hepatitis B virus and perhaps other hepatotropic viruses are also not uncommon. The surveillance of such children and long-term follow-up are necessary. There is already compelling evidence to indicate that hepatocellular carcinoma, prevalent among young adults in our environment, may be related to hepatitis B antigenaemia persisting over several years. The need for an effective vaccine against hepatitis B virus infection cannot, therefore, be over-emphasized.

A 6-day-old female (Bison bison) was inoculated with 10 million sporocysts of the B1 isolate of Sarcocystis cruzi originally obtained by feeding heart of a naturally infected cow (Bos taurus) to a laboratory-raised coyote. The bison became febrile, lethargic, and anorectic at about 25 days after inoculation of the sporocysts, and was euthanatized 3 days later. There were widespread hemorrhages, hepatitis, myocarditis, nephritis, and enteritis; intravascular meronts were found in the adrenal cortex and lamina propria of the small intestine. Another 7-day-old male bison was inoculated with 100,000 sporocysts of the same B1 isolate of S cruzi. Except for mild fever and transient diarrhea, the bison remained clinically normal. Sarcocysts were found at necropsy on day 76 after inoculation. It was concluded that S cruzi of cattle is transmissible to bison.

Fatal Yersinia pseudotuberculosis infection was diagnosed in 3 bushbabies (Galago crassicaudatus) in a large prosimian colony. The clinical signs were diarrhea, dyspnea, hyperthermia, dehydration, and lethargy. Histologically, the disease was characterized by lesions of ulcerative enterocolitis, necrotizing hepatitis, splenitis, lymphadenitis, and nonsuppurative pneumonitis.

The clinical signs and gross and microscopic lesions of Lassa virus infection in the rhesus monkey are described. Of 17 monkeys infected with Lassa virus, nine died or were killed when moribund. The clinical signs were lethargy, aphagia, constipation, fever, conjunctivitis, and skin rash. Pulmonary congestion, pleural effusion, pericardial edema, hydropericardium, and a few visceral hemorrhages were present grossly. Major microscopic lesions were necrotizing hepatitis and interstitial pneumonia. Other microscopic changes were present in the heart, small intestine, spleen, lymph nodes, kidney, urinary bladder, adrenal glands, and central nervous system; however, most of these lesions were mild. In fact, death could not always be attributed to the morphologic changes; therefore, function alterations must be examined.

Seven horses developed clinical or subclinical hepatitis 48 to 87 days after administration of tetanus antitoxin. One horse had mildly high hepatic enzyme activity 120 days after inoculation with tetanus antitoxin. The first horse developed signs of depression, lethargy, and anorexia. During hospitalization, signs of hepatoencephalopathy were noticed, and laboratory data were consistent with hepatic disease. Another horse that was found dead had gross and histologic lesions compatible with serum hepatitis. Screening of serum gamma-glutamyltransferase (GGT) and aspartate transaminase activities were used to investigate the remaining horses in the herd. High GGT activities (71 to 206 IU/L) were detected in 5 additional herd members. These horses appeared clinically normal, apart from 2 reports of nasal photosensitization and an aborted fetus. In 3 horses, high serum GGT activity persisted over a 44-day testing period. All affected horses had been given tetanus antitoxin within 12 hours of parturition, and a common source of vaccine was identified for 7 horses. Findings in this group of horses indicate that clinical and subclinical serum hepatitis can develop after administration of tetanus antitoxin.

A 56-year-old Saudi male was admitted with abnormal liver chemistry values and a > 5-month history of lethargy, malaise, anorexia, and jaundice. Extensive investigations did not establish an etiological diagnosis. Liver histology confirmed the clinically apparent aggressive hepatitis with fibrosis but gave no clue to its etiology. The patient was empirically treated with alpha-interferon for presumed non-A, non-B hepatitis, with clinical and biochemical worsening. Interferon was discontinued and the patient was started on immunosuppression. Dramatic clinical and biochemical improvement occurred, with normalization of the liver chemistry within 4 weeks. The patient has been followed-up for 12 months and has not suffered a relapse. This case highlights the etiological heterogeneity of chronic active hepatitis. The entity of autoimmune chronic active hepatitis is unclear, and perhaps it is better defined as steroid-responsive hepatitis. Steroid-responsive hepatitis should always be considered in cases of cryptogenic chronic active hepatitis.

Disseminated infection with Mycobacterium avium complex is described in 3 adult Siamese cats. All cats were the result of father-daughter matings. Clinical signs included anorexia, weight loss, and lethargy. Physical examination revealed pale mucous membranes, lymphadenopathy, splenomegaly, and pyrexia. Nonregenerative anemia was detected in all 3 cats, and macrocytosis was observed in 2. An antemortem diagnosis of mycobacterial infection was made on the basis of identification of acid-fast bacilli in tissue aspirates. The cats died or were euthanatized owing to clinical deterioration, despite antibiotic treatment. Necropsy findings included granulomatous lymphadenitis, enterocolitis, pneumonia, cellulitis, myelitis, and hepatitis. Organisms from the Mycobacterium avium complex were identified in bacteriologic cultures of tissue samples.

We studied 57 infants < or = 14 days of age referred for possible enterovirus (EV) infection to assess the accuracy of that clinical diagnosis and describe the natural history of neonatal EV infection. Twenty-nine neonates proved to have EV infection, 23 had illnesses compatible with (but not proven to be) EV infection, and 5 had alternative diagnoses: bacterial infections (2); herpes simplex virus infection (1); and metabolic disorders (2). Neonates with proved EV infection were generally full term and had uncomplicated immediate postnatal periods but high percentages of ill contacts. Neonatal symptoms and signs included fever, irritability, anorexia, lethargy, hypoperfusion, rash, jaundice and respiratory findings. Laboratory abnormalities included cerebrospinal fluid (CSF) pleocytosis, chest radiograph infiltrates, abnormal urinalyses and elevated transaminases. EVs were most commonly isolated from CSF and rectum/stool but also frequently from serum and urine. Five EV-infected patients had severe multisystem disease (pneumonitis, hepatitis, thrombocytopenia, bleeding and meningitis), requiring supportive care and lengthy hospitalizations. All survived, 2 with residual hepatic dysfunction. Markers of severe disease included: early age of illness onset (especially Day 1 of life); maternal viral symptoms at delivery; absence of fever and irritability; tachypnea; lethargy; abdominal distension; hepatomegaly; and positive serum viral culture. These data support conservative management of ill infants < or = 2 weeks of age and suggest that antiviral therapy for neonatal EV infection would be optimally targeted at infants with early onset illness, multisystem disease and/or viremia.

We clarified the clinical and immunogenetical differences between patients with autoimmune hepatitis (AI-CAH), and patients with type C chronic active hepatitis (C-CAH) and type B chronic active hepatitis (B-CAH) who were positive for autoantibodies and hyperglobulinemia. While histories of blood transfusion, intravenous drug abuse and tattoo were seen frequently in patients with type C-CAH, they were rare in patients with AI-CAH. The severe subjective symptoms including anorexia, lethargy, icterus, high fever and extrahepatic manifestations, and severe abnormality of biochemical data were seen in AI-CAH predominantly. Ongoing or past infection of HCV was seen in only 14% of patients with AI-CAH. HLA-DR4 was the most frequently associated with AI-CAH (89%) and 6 DR4-negative patients were positive for DR2. HLA-DNA typing showed that there was no significant difference in the frequency of DR4-associated Dw-alleles between the patients and controls who were positive for DR4. These findings suggest that the basic amino acid at position 13, which is present only on the DR2 and DR4 B1 molecules (Arg on DR2 and His on DR4), may contribute to the susceptibility to autoimmune hepatitis of Japanese. Thus, we conclude that AI-CAH is a genetically restricted, disease, and different from C-CAH which is a viral infectious disease.
