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.

The effects of weight reduction on hepatic test results and physical findings related to the liver were retrospectively evaluated in 39 overweight patients screened to exclude other factors affecting the liver. An additional 11 overweight patients with primary liver disease were retrospectively evaluated to compare the effect of weight reduction in patients with liver disease with its effect in those without primary liver disease. This study showed that in overweight adults without primary liver disease, a weight reduction of greater than or equal to 10% corrected abnormal hepatic test results, decreased hepatosplenomegaly, and resolved some stigmata of liver disease. In similarly studied overweight patients with primary liver disease, some findings improved, but the changes did not correlate with a greater than or equal to 10% weight loss. Increased alanine aminotransferase activity was the most frequent hepatic enzyme abnormality in this population. For every 1% reduction in body weight, alanine aminotransferase activity improved by 8.1%. After other causes of liver disease are eliminated by clinical and biochemical parameters, weight reduction should be tried for overweight patients with abnormal hepatic test results in the absence of obvious primary liver disease as judged by clinical and biochemical parameters before extensive and expensive studies are undertaken.

A 3 years old girl presented with clinical feature of an acute hepatitis-like illness, with jaundice, hepatosplenomegaly, high alanine aminotransferase activity (ALT) and high gamma-globulin values. We were able to demonstrate high titre of anti-liver-kidney microsome antibodies type 1 (LKMA1) in the serum of this patient using immunofluorescence, ELISA (Enzyme-linked immunoabsorbent assay) and Western blot (WB) analysis. This observation together with the liver morphology and after excluding other possible causes of hepatitis established the diagnosis of chronic active hepatitis associated with anti-LKM1 antibody. Immunosuppressive therapy was therefore started immediately.

The serum activities of monoamine oxidase (MAO), gamma-glutamyl transferase (GGT) and glutamic dehydrogenase (GDH) enzymes were measured in 25 patients with Schistosoma mansoni infection (Group I), 26 patients with schistosomal hepatosplenomegaly and ascites (Group II) and 21 normal controls. The activities of these enzymes were compared with those of serum aspartate aminotransferase (AST), alanine aminotransferase (ALT) and alkaline phosphatase (ALP). The mean levels of MAO, GGT and GDH of Group I were not significantly different from controls. The mean levels of MAO and GGT in Group II, however, were significantly different from corresponding mean levels of Group I and the controls at P less than .001. Changes in the mean level of GDH and ALT were not significant. By contrast, the levels of AST and ALP in both groups showed significant elevation over control levels at P less than .001. These results indicate that estimation of the two enzymes MAO and GGT may aid in the biochemical differentiation of the stages of schistosomiasis and their associated hepatic complications.

Nitrobenzene (NBZ) is primarily employed as an oxidizing agent in the synthesis of analine and benzene compounds. It produces myelotoxic effects and effects on erythrocytes in both animal models and man. Reported hepatosplenomegaly and effects on the bone marrow are indicators that NBZ may be immunotoxic. In these studies, female B6C3F1 mice were exposed to 30, 100 and 300 mg/kg of NBZ in corn oil by gavage for 14 consecutive days. To assess the immunotoxic potential of NBZ, body and organ weights were determined and selected immunologic and host resistance responses were studied. In these studies, the liver and spleen appeared to be the primary target organs. Both liver and spleen weights were dose dependently increased. Gross histopathologic examinations revealed significant changes in the spleen, consisting of severe congestion of the red pulp areas with erythrocytes and reticulocytes. Serum chemistry profiles showed increases in alanine aminotransferase and aspartate aminotransferase activities, indicating liver toxicity. Hematologic studies showed a decrease in erythrocyte number and a concomitant increase in mean corpuscular hemoglobin and mean corpuscular volume. A dose-dependent increase in peripheral reticulocytes was also seen. DNA synthesis was enhanced, as was the number of formed elements and the number of monocyte/granulocyte stem cells in the bone marrow of treated mice. IgM responses were decreased and the phagocytic activity of macrophages in the liver was dose dependently increased with a concomitant decrease in the activities in the spleen and lung. Other immunological parameters examined were unchanged. Host resistance to microbial or viral infection was not markedly altered by NBZ; however, there were trends towards increased susceptibility where T-cell function contributes to host defense. These data indicate that NBZ-induced hemolysis and liver injury are linked to the observed alterations in bone marrow activity.

A 62-year-old man was admitted to our hospital because of severe jaundice and fever. Physical examination demonstrated hepatosplenomegaly. The laboratory data revealed elevated serum bilirubin, alkaline phosphatase, lactate dehydrogenase, aspartate aminotransferase and alanine aminotransferase, and the reduced hepaplastin test (Normotest). Computed tomography showed hepatosplenomegaly and swelling of the paraaortic lymph nodes. Although he was treated with antibiotics and steroids, he died of hepatic failure 22 days after admission. At autopsy, his liver weighed 1910 grams, and a histological examination of the liver revealed marked infiltration of CD30 (Ki-1) positive lymphoma cells. He was diagnosed as having non-Hodgkin lymphoma, large cell anaplastic type, Ki-1 lymphoma. We herein report our findings of this very rare case of Ki-1 lymphoma associated with hepatic failure.

A women, 50 years old, has been observed for 4 years because of recurrent infiltrations in both lungs. Biopsy of those lesions revealed sarcoid-like granulomas. Tubercle baccilli were not present in those lesions nor in the sputum or bronchial washings. Anti-tuberculosis therapy was without effect. On admission to our hospital she was in good performance state. There was an infiltration in the base of the left lung. Hepatosplenomegaly was observed on USG examination. Aspartate aminotransferase was 49 UI/l, alanine aminotransferase 70 UI/l. Alkaline phosphatase was 167 UI/l and the titer of antimitochondrial antibodies was 1:2000. Primary biliary cirrhosis was suspected, but the patient refused liver biopsy. Prednisone in the dose of 60 mg per day was given to suppress the granuloma formation in the lungs. During this treatment there was a decrease in size of liver and spleen, lung lesion disappeared and the titer of antimitochondrial antibodies decreased to 1:40. After 3 months of treatment the dose of prednisone was reduced gradually. When she was receiving 15 mg of prednisone every other day the titer of antimitochondrial antibodies rose to 1:8000 and the activity of alkaline phosphatase to 448 UI/l. At this time she accepted liver biopsy. Primary biliary cirrhosis was diagnosed. The possible connection between sarcoid-like granulomas in the lungs and the primary biliary cirrhosis is discussed.

The characteristics of Epstein-Barr virus (EBV)-associated infectious mononucleosis (IM) in Chinese children are rarely reported. To evaluate the clinical presentations and risk factors for complications of EBV-associated IM in previously healthy children in Taiwan, hospitalized children with the diagnosis of IM due to EBV infection from January 1998 to December 2002 were enrolled. Patients had to fulfill the serologic criteria for the diagnosis of primary EBV infection [viral capsid antigen immunoglobulin M (IgM)-(+), viral capsid antigen IgG-(+), and anti-Epstein-Barr nuclear antigen (EBNA) antibody-(-) with exclusion of other concurrent infections or underlying diseases]. Ninety eight children were eligible, with 79% younger than 5 years old (mean, 4.0 +/- 2.3 years). The male-to-female ratio was 2:1. Nearly all patients suffered from fever (mean duration 10.3 +/- 6.0 days). Cough/rhinorrhea, tonsillopharyngitis, cervical lymphadenopathy and hepatosplenomegaly were found over half of the patients. Atypical lymphocytosis (mean, 12 +/- 13%) and elevated serum aspartate aminotransferase (AST; mean, 167 +/- 183 IU/L) and alanine aminotransferase (mean, 221 +/- 222 IU/L) were the most striking laboratory findings. Various complications, including hematologic, hepatobiliary, central nervous system, and obstructive airway problems occurred in about 20% of patients with significantly prolonged course of hospitalization. All patients recovered uneventfully under supportive and immunomodulating management. Female gender, no signs of tonsillopharyngitis, white blood cell count < or =10,000/mm3 and AST > or =150 IU/L were significant risk factors for the occurrence of complications. Clinicians should monitor such patients closely and give proper treatment to decrease possible morbidity or even mortality should complications occur.

A 17-year-old girl previously in good health presented with a 2-month history of recurrent, high-grade fever; general fatigue; anorexia; a 10-kg weight loss; and multiple, painful, reddish skin lesions on the lower abdomen. Some lesions were ulcerated, with an oily yellowish brown discharge. A systemic review was unremarkable other than bleeding from the nose. Her medical and family histories were unremarkable. On examination, the patient was pale, jaundiced, and febrile (temperature of 39 degrees C). She had enlarged lymph nodes in the axillary and inguinal areas. There was moderate hepatosplenomegaly. Local skin examination revealed multiple erythematous, tender, and firm subcutaneous nodules of variable size (1-2 cm) on the lower abdomen. Some nodules were ulcerated, with oily yellowish brown discharge and overlying ecchymosis (Figures 1 and 2). Mucous membranes were free of lesions. Laboratory investigations showed pancytopenia, an elevated erythrocyte sedimentation rate (>80 mm/h), normal renal function tests, abnormal hepatic function tests (alanine aminotransferase 172 U/L, aspartate aminotransferase 229 U/L, alkaline phosphatase 725 U/L, and total bilirubin 100 mmol/L [normal range 0-18 mmol/L]), conjugated bilirubin 45 mmol/L (normal range 0-5 mmol/L), and high triglycerides 855 mg/dL (normal range 20-200 mg/dL). Prolonged prothrombin time, 26 seconds (normal range 13-16 seconds); prolonged activated partial thromboplastin time, 61 seconds (normal range 26-38 seconds); positive disseminated intravascular coagulation studies evidenced by low fibrinogen, 74 mg/dL (normal range 160-350 mg/dL); and positive fibrinogen degradation products were also noted. Throat, midstream urine, and blood culture results were negative. Serologic tests for syphilis, HIV, and hepatitis B and C viruses were negative. Epstein-Barr virus and cytomegalovirus serologic values revealed evidence of past infection. Tuberculin and Coombs tests were negative. The alpha1-antitrypsin level was normal. Antinuclear and anti-smith antibodies, rheumatoid factor, and cryoglobulins were negative. CT showed enlarged lymph nodes in the axillary and inguinal areas, bilateral small pleural effusion, moderate hepatosplenomegaly, severe fatty infiltration of the liver, and thickening of lower abdominal subcutaneous tissue. A liver biopsy showed steatohepatitis. Bone marrow aspirate and trephine were normal. A deep punch biopsy of a nodule from the right lower abdomen revealed lobular panniculitis with atypical lymphocytes and large macrophages with cytophagocytosis ("beanbag" cells) (Figures 3 and 4). Immunohistochemistry showed that these atypical cells were positive for CD3, CD8, granzyme B, and perforin, and negative for CD56. T-cell gene rearrangement studies on skin lesions revealed a monoclonal T-cell receptor (gamma-chain) gene rearrangement, supporting the diagnosis of subcutaneous panniculitis-like T-cell lymphoma. On presentation, the initial treatment included 6 U of fresh frozen plasma, 2 U of packed red blood cells, and 2 g IV fibrinogen for 3 consecutive days. The patient was started on prednisolone 60 mg orally once daily and cyclosporine A 5 mg/kg/d orally in two divided doses. The fever and other systemic symptoms and skin lesions resolved within 2 weeks after the treatment. The prednisolone dose was tapered gradually, and a maintenance dose of cyclosporine A was continued. The patient's condition remained in remission at 12-month follow-up; there was no evidence of clinical relapse.

Niemann-Pick type C (NP-C) disease is a neurovisceral lysosomal storage disease characterized by neurologic dysfunction, hepatosplenomegaly, and early death. Natural history studies are very difficult to perform due to the low incidence and high heterogeneity of disease in the human population. Sixteen cats with a spontaneously occurring missense mutation in NPC1 were evaluated over time to define the progression of neurologic and hepatic disease. Affected cats had remarkably regular onsets of specific signs of cerebellar and vestibular system dysfunction with progressive severity of dysfunction quantified by postrotatory nystagmus and brain stem auditory evoked response measures. NP-C disease cats also showed increasing serum activity of alanine aminotransferase, asparate aminotransferase, and cholesterol with advancing age. Affected cats lived to a mean age of 20.5 +/- 4.8 wk. CNS and hepatic lesions were similar to those described in human patients. These data are the first to document progressive hepatic disease in the feline model and demonstrate the importance of liver disease as part of the NP-C disease phenotype. Both neurologic and hepatic measures of disease onset and severity can be used as a baseline with which to assess the efficacy of experimental therapies of NP-C disease in the feline model.
