Knowledge of the natural history of symptomatic congenital cytomegalovirus (CMV) infection in the newborn is essential in order to anticipate complications and assess the potential benefit from antiviral therapy. To define the disease course we reviewed data on 106 neonates with symptomatic congenital CMV infection diagnosed and managed by the investigators. Petechiae, jaundice and hepatosplenomegaly were each noted in 70% or more patients. Microcephaly was noted in 54 of 102 (53%) at birth. Elevated alanine aminotransferase, conjugated hyperbilirubinemia and thrombocytopenia were seen in 83, 81 and 77%, respectively. Eighty-six percent had at least two of the manifestations highly suggestive of congenital infection. Platelet count fell to its nadir during the second week of life whereas elevated alanine aminotransferase and direct bilirubin persisted past the first month. In spite of the difficulty in assessing central nervous system function in the newborn, evidence of damage was present in the majority. Seventy-two had microcephaly, poor suck, lethargy/hypotonia or seizures. Abnormal computerized tomographic scan was present in 16 of 20 (80%) and decreased hearing in 20 of 39 (56%). Cerebrospinal fluid protein was greater than 120 mg/dl in 24 of 52 (46%) and this elevation was associated with neurologic abnormalities as well as hearing loss. The mean length of hospital stay was 13 and 22.4 days for term and preterm infants, relatively. Thirteen infants (12%) died during the first 6 weeks of life. Disseminated CMV infection with multiorgan involvement was evident in 7 of 9 at postmortem examination. We conclude that neonates with symptomatic congenital CMV infection have a multi-system disease with significant morbidity and mortality.

A 52-year-old woman presented slight fever, diffuse papular skin rash and painful cervical lymph node swelling. Her lymph node swelling generally up to 3 cm in diameter, with petechiae on the lower legs and hepato-splenomegaly within a few weeks. ESR was 45 mm/h, Hb 10.0 g/dl, RBC 345 x 10(4)/microliter, WBC 22,600/microliter (atypical lymphocyte 47%), PLT 1.0 x 10(4)/microliter, GPT 91 U/L, gamma-globulin 34.3%, EBV-VCA x 2,560, EBNA x 20, and anti-rubella antibody x 512. The biopsied cervical lymph node showed histologic features of effacement of nodal architecture by an exuberant vascular proliferation accompanied with infiltration of the immunoblasts, and was diagnosed as immunoblastic lymphadenopathy (IBL)-type lymphadenopathy. The pulse therapy of methylprednisolone and high dose of gamma-globulin improved lymphadenopathy, thrombocytopenia and anemia. IBL-type lymphadenopathy after infection of rubella virus may be different from true IBL, but is important to discuss the pathogenesis of IBL.

It has been generally accepted that congestive heart failure does not lead to fulminant hepatic failure, unless it is associated with cardiac shock or low cardiac output. Only three cases have been reported, in which liver congestion is followed by fulminant hepatic failure without a history of shock or low cardiac output. Here we present a case of a 48-year-old man with dilated cardiomyopathy and pulmonary infarction, who developed fulminant hepatic failure from congestion. When he was admitted for the control of diabetes mellitus, hepatomegaly of 3-finger breadth and marked cardiomegaly without pulmonary congestion was noted. Diabetes was controlled using insulin. But 3 weeks after admission, he sometimes complained of back dullness because of pulmonary infarction. His heart gradually increased in size, and Jugular venous dilatation and pretibial pitting edema also worsened. Jaundice was noted and serum GOT and GPT increased. A large liver of 6-finger breath below the right costal margin was able to be felt. But within one week, the size of the liver markedly decreased and the signs of hepatic failure such as jaundice, hepatic encephalopathy and numerous petechiae appeared. Blood pressure was maintained and no hypotension or cardiac shock was noted. The patient died of fulminant hepatic failure on the 20th days after onset of the hepatic failure. The autopsy revealed liver atrophy with severe central lobular necrosis, and thrombus in the right main pulmonary artery which caused severe pulmonary infarction. The mechanism of fulminant hepatic failure not accompanied with low cardiac output is discussed.

Adult wild-trapped opossums were infected with Leishmania donovani (Khartoum strain, WR 378) and evaluated as an animal model of visceral leishmaniasis. All infected opossums died within 32 days. Loss of body fat, hepatomegaly, and petechiae of skin and abdominal musculature were seen at necropsy. Microscopically, numerous amastigote-laden macrophages were seen in histologic sections of liver, spleen, and lymph nodes; fewer parasite-laden macrophages were in the bronchial-associated lymphoid tissues and renal glomeruli. Hematological findings included thrombocytopenia (terminal), neutropenia, and lymphopenia. Blood lymphocyte blastogenesis in response to concanavalin A and phytohemagglutinin was decreased markedly at day 24 post-infection (PI). Serum antibodies (1:40 dilution) to promastigotes of L. donovani were detected in five of eight infected opossums tested on days 10 and 24 PI. Total bilirubin concentrations and alanine aminotransferase and aspartate aminotransferase activities were increased after day 25 PI. Activated partial thromboplastin times and one-stage prothrombin times were prolonged before death. Concurrently, factors V, VIII, and XII activities were decreased.

Ten patients with infections (8 neonates and 2 infants) were treated with 10.2 mg/10.2 mg/kg-37.7 mg/37.7 mg/kg of imipenem/cilastatin sodium (IPM/CS) b.i.d. or t.i.d. by a 1-hour intravenous drip infusion. The plasma concentrations of IPM/CS were determined in 5 of the 10 patients and in the cerebrospinal fluid of 1 patient of the 5. 1. The patients studied included 5 with pneumonia and 1 each with urinary tract infection, omphalitis, suspected meningitis, periproctal abscess and suspected septicemia. Clinical efficacy was evaluated in 9 patients: the patient with suspected meningitis was excluded from the clinical evaluation because the infection was doubtfully due to bacteria. Responses were excellent in 4 and good in 5 patients. No patient with a poor response was observed. All of the 6 etiological isolates obtained from 5 patients (2 strains of Staphylococcus aureus and 1 each of Escherichia coli, Enterococcus faecalis, Streptococcus agalactiae and Bacteroides fragilis) were eradicated. 2. As for side effects, rash was observed in 1 patient and petechiae accompanied by decreases in platelets and reticulocytes and increases in GOT and GPT were observed in another. Other abnormal laboratory test values in addition to the above abnormalities consisted of an increase in GPT in 1 patient and increases in GOT and GPT in another. These side effects and abnormalities in laboratory test values were mild and normalized after discontinuation or completion of IPM/CS administration.(ABSTRACT TRUNCATED AT 250 WORDS)

Nineteen weanling ponies and 1 adult pony were given a single oral dose of aflatoxin B1 (AFB1). Dosages were: 0, 0.5, 1, 2, 4, 5, 6, and 7.4 mg of AFB1/kg of body weight. Vital signs were monitored, and whole blood and serum collected for analysis of serum enzymes, prothrombin time, blood cell counts, and serum urea nitrogen. Ponies that died were examined for gross lesions, and tissues were collected for histopathologic examination and analysis of AFB1 and AFM1 residues. Two of the 4 ponies given the 2 mg/kg dose and all ponies given the larger dosages died within 76 hours. Clinical signs included increased rectal temperature, faster heart and respiratory rates, abdominal straining, bloody feces, and tetanic convulsions. At necropsy, ponies that died of acute aflatoxicosis showed visceral petechiae and hepatic focal lesions. Histopathologic changes included severe hepatic necrosis, vacuolation, and bile duct hyperplasia. Aflatoxins B1 and M1 were recovered from liver, kidney, skeletal muscle, and gastrointestinal contents. One other pony given the 2 mg/kg dose died 32 days after dosing, and 1 control pony died after 70 days. Continuous elevations in prothrombin time and serum aspartate aminotransferase, alanine aminotransferase, and gamma-glutamyl transpeptidase levels were observed in ponies dosed at 4 mg/kg or more. Significant (P less than 0.05) elevations in these values, which peaked 2 to 3 days after dosing, were seen in ponies given the 2 mg/kg dose. This group also had significant increases over controls in PCV and hemoglobin concentration 5 days after dosing.

KW2083 7-N-(p-hydroxyphenyl) mitomycin C is a mitomycin C derivative, but not its masked compound. KW2083 differs from mitomycin C in various points. A phase I study of KW2083 by single intravenous injection was performed in 21 patients with advanced solid tumor. The dose limiting factor of this drug is marrow depression, and 70mg/m2 causing marked thrombocytopenia was determined as maximum tolerated dose. The thrombocyte count and the WBC count reached to nadir the minimum 2 to 3 weeks after and 1 to 2 weeks after the administration and recovered in 1 to 2 weeks and in 2 to 3 weeks respectively. As gastrointestinal symptoms, nausea or vomiting (38.1%), and anorexia (28.6%) occurred soon after the administration, and stomatitis and diarrhea were also observed in one case each. In addition, petechia, hemorrhagic tendency and fever were found in one case each. Patients receiving 70mg/m2 showed slight alopecia and transient slight in GOT and GPT elevation.

A national surveillance program for congenital cytomegalovirus (CMV) disease was initiated in 1990. In 4 years 285 cases were reported without seasonal patterns. Mean birth statistics were as follows: gestational age, 36 weeks; weight, 2,224 g; length, 45 cm; and head circumference, 30 cm. Of the infants 68% had CNS involvement, which was significantly (P < .005) associated with a direct bilirubin level of > or = 3 mg/dL, petechiae, an alanine aminotransferase level of > 100 U/L, a platelet count of < or = 75,000/mm3, hepatomegaly, and splenomegaly (P < .05). Maternal demographics revealed that the mean age was 23 years (range, 13-38 years), 59% were white, 33% were black, 47% had low incomes (receiving Medicaid), and 45% were primiparous. Compared with 1990 birth statistics in the United States, mothers of infants with congenital CMV disease were younger, and a greater percentage of these mothers were black. Two distinct maternal groups were identified on the basis of age, socioeconomic status, and parity. This finding may reflect different modes of transmission and suggest target populations for future CMV vaccine initiatives.

A 31-year-old women with chronic active hepatitis B (HBs antigen-positive, HBe antigen-negative) developed a painful petechia rash on both lower legs and the inner surface of the thighs. Histology of a skin biopsy revealed leucocytoclastic vasculitis. The affected skin areas contained HBs antigen and immunoglobulins. Immunosuppressive treatment with initially 60mg/d prednisolone improved the skin condition but activated the chronic hepatitis, GPT rising up to 240 U/l. The steroid treatment had to be discontinued. Subsequently the transaminases became normal but the vasculitis foci recurred. The patient was therefore given alpha-interferon, three times 5 mill. IU weekly subcutaneously for 6 months. The skin lesions disappeared and the circulating HBV-DNA decreased. But the HBs antigen could not be eliminated. It is to be noted that 12 months after the end of the alpha-interferon treatment the vasculitis has not recurred. - This case and published reports indicate that interferon treatment is effective against HBV-associated and immunoglobulin-complex mediated disease.

Lymphocytic/plasmacytic colitis was diagnosed in 14 cats during a 5-year period. Purebred cats were affected significantly (P < 0.001) more often than were nonpurebred cats. Six cats were male and 8 were female. Mean age at onset of clinical signs was 5.1 years (range, 0.5 to 9 years). Hematochezia, observed in 13 cats, was the most commonly reported sign; diarrhea was reported in 11 cats. Mildly high serum alanine transaminase activity and hypokalemia were frequent biochemical abnormalities. Campylobacter sp was cultured from the feces of 1 cat. On endoscopic examination, petechia and hyperemia of the colonic mucosa were detected in 7 of 8 cats. Cats were initially treated with dietary management alone or with a combination of dietary and pharmacologic management. Clinical signs in 7 of 11 treated cats completely resolved, whereas signs in 3 cats were considered improved. One cat was euthanatized when an inadequate response to treatment was observed. Most cats were eventually maintained on dietary management alone.
