Between March 1986 and March 1989, 20 children were diagnosed as having liver abscesses at the Pediatric Department of the Central Hospital in Valencia. 10 were amebic and 10 pyogenic abscesses. 85% occurred in children and 15% in infants. 15 of them (75%) were located in the right lobe, 80% of amebic abscesses had positive serological tests. An etiologic agent was found in 50% of the pyogenic abscesses (3: E. coli, 2: S. Aureus). 80 to 90% of patients presented abnormal prothrombin time. Sedimentation rate was very high in both groups, even at the discharge time. Hepatomegaly, fever, anemia and abdominal pain were the main clinical features. The macroscopic aspect of the aspirate was not helpful in the diagnosis. 60% of amebic liver abscesses needed only medical treatment but 80% of pyogenic abscesses deserved medical treatment and needle aspiration.

A 27-year-old female patient with alcoholic cirrhosis was reported. She was admitted to the hospital because of jaundice and ascites after heavy drinking. She had a history of drinking Japanese Sake in quantities of more than 5 go/day (900 ml/day) for 7 years. On admission, she was icteric, and had both hepatosplenomegaly and ascites. Laboratory data showed an elevation of serum transaminase and bilirubin, and a decrease in the albumin and prothrombin values. A biopsy specimen of the liver showed pericellular fibrosis, fatty change, Mallory bodies and regenerative nodules, and revealed findings compatible with alcoholic cirrhosis. A 99mTc-N-pyridoxyl-5-methyltryptophan scintigram showed hepatomegaly. On the 99mTc-phytate scintigram, the uptake of radioisotope to the liver was markedly decreased with the increased uptake to the spleen and bone marrow. Even 6 months after the onset, poor visualization of the hepatic image on 99mTc-phytate scintigram continued. This is the first report of alcoholic cirrhosis demonstrating a long-term poor visualization of the hepatic image on 99mTc-phytate scintigraphy.

The authors describe a child with Budd-Chiari syndrome secondary to membranous obstruction of the hepatic veins and a web in the inferior vena cava. Transhepatic catheter venography demonstrated the occlusion, which was recanalized and dilated percutaneously via a transhepatic approach. Hepatomegaly and ascites decreased promptly and the prothrombin time became normal.

Phenytoin hepatotoxicity is a serious idiosyncratic reaction that occurs in less than one percent of patients. The onset of symptoms occurs early in therapy, usually within the first six weeks. Presenting symptoms often include fever, rash, lymphadenopathy, hepatomegaly, anorexia, and myalgias or arthralgias. Other significant findings that may develop throughout hospitalization are jaundice, periorbital or facial edema, and splenomegaly. The following alterations in liver function tests are associated with phenytoin hepatotoxicity: elevations in serum aminotransferases, lactic dehydrogenase, alkaline phosphatase, bilirubin, and prothrombin time. Rechallenges, lymphocyte stimulation test, and liver biopsy have been used to aid in the diagnosis. Rechallenge is the most definitive diagnostic approach; however, its use is limited by the potential of a fatal reaction. Although the exact mechanism of phenytoin hepatotoxicity is unknown, the majority of literature supports a hypersensitivity mechanism. The severity of this adverse effect ranges from self-limiting to fatal. Since 1965 six fatal cases have been reported. To date, sufficient evidence is not available to establish treatment guidelines. Discontinuation of phenytoin therapy is warranted.

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.

The effect of proctocolectomy on the primary sclerosing cholangitis that frequently is associated with chronic ulcerative colitis in patients with both conditions is unknown. We have studied prospectively the progression of clinical, biochemical, cholangiographic, and hepatic histologic features in 45 patients with both primary sclerosing cholangitis and chronic ulcerative colitis to compare these variables in the 20 patients who had undergone proctocolectomy with the 25 who had not. The two groups were similar initially with regard to clinical, biochemical, cholangiographic, and hepatic histologic findings. All patients were followed for a minimum of 1 yr and overall duration of follow-up was similar in both groups (4.1 vs. 3.9 yr). Clinically, new onset of hepatomegaly, splenomegaly, esophageal varices, and ascites did not differ in patients with and without proctocolectomy. Biochemically, the serial changes in bilirubin, alkaline phosphatase, aspartate aminotransferase, prothrombin time, and albumin were similar. Histologic progression on liver biopsy did not differ between groups, nor did changes on serial cholangiograms. Proctocolectomy also had no effect on survival. We conclude that proctocolectomy for chronic ulcerative colitis has no beneficial effect on the primary sclerosing cholangitis in patients with both diseases.

We determined the clinical and biological correlates of coagulopathy in a large series of patients with untreated childhood acute leukemia. Twenty-five of 805 children with acute lymphoblastic leukemia (ALL) (3.1%) and 27 of 195 with acute myeloid leukemia (AML) (13.8%) met any two of three requirements for a coagulation disorder: fibrinogen level less than 150 mg/dL; fibrin degradation products greater than 10 micrograms/mL; and prolongation of prothrombin time (PT) greater than 12 seconds, activated partial thromboplastin time (PTT) greater than 45 seconds, or thrombin time (TT) greater than 18 seconds. Patients with ALL complicated by abnormal coagulation were more likely to be boys and to have a T-cell immunophenotype, a high leukocyte count, a mediastinal mass, leukemic involvement of the CNS, hepatosplenomegaly, and L2 blast cell morphology. These features were highly interrelated, with only T-cell markers and CNS involvement achieving independent significance in a multivariate logistic regression model. Hepatomegaly, blast cell morphological subtype (French-American-British [FAB] M3, M4, and M5) and age less than 2 years were each associated with coagulopathy in patients with AML, although age failed to retain importance after logistic regression analysis. The presence of coagulopathy at diagnosis of ALL did not influence the rate of remission induction (P = .55). By contrast, only 14 of 27 children with coagulopathy at diagnosis of AML achieved a complete remission (CR), compared with 129 of 168 other patients who lacked this complication (P = .003). After multivariate analysis, coagulopathy remained independently associated with failure to attain remission in AML (P = .02). Fatal hemorrhagic complications arising in the CNS or lungs accounted for nine of the 13 induction failures in this group. The presence or absence of coagulopathy had no discernible influence on treatment outcome among patients with either ALL or AML who attained a CR. Laboratory evidence of a coagulation defect may be useful in identifying patients with AML who have a greater risk of induction failure and, hence, require close surveillance and intensive replacement therapy to prevent fatal hemorrhagic complications.

As the results of treatment in Wilson's disease are so dependent on the stage at which penicillamine therapy is started, the antecedent history in 34 patients with Wilson's disease was analysed with particular respect to the earliest manifestations of the disease. Lethargy and anorexia (70%) jaundice (56%) and abdominal pain (48%) were the commonest symptoms and less common were intellectual deterioration (22%) and recurrent epistaxes (22%). The duration of symptoms before diagnosis ranged from five days to three years (mean 10.5 months) and in only five of the patients was the diagnosis established before referral. Analysis of the physical signs at presentation showed hepatomegaly (81%) and splenomegaly (70%) to be common and the only signs which were significantly more common in the 13 fatal cases were jaundice and ascites. In three of these and in one other patient who survived the clinical course was exceptionally severe and was indistinguishable from fulminant hepatic failure. Based on the severity of abnormality of serum aspartate aminotransferase, bilirubin, and prothrombin time on admission a prognostic index was derived which enabled complete separation of fatal and nonfatal cases and when subsequently used in a further nine index cases correctly predicted the outcome. Two further cases found to have indices in the fatal category did well after liver transplantation, which needs to be considered as soon as the diagnosis is established in cases with such severe liver damage.

Five patients had amiodarone hepatotoxicity detected on routine biochemical monitoring. Symptoms attributable to hepatotoxicity were minimal or absent; reversible hepatomegaly was seen in two patients, whereas three patients had signs of nonhepatic amiodarone toxicity before or with hepatotoxicity. Serum aminotransferase levels were elevated in all patients and alkaline phosphatase levels in four; no patient had hyperbilirubinemia or prolongation of the prothrombin time. Light microscopy showed steatosis, cellular degeneration, and cellular necrosis in the biopsy samples of four patients, whereas the fifth patient's sample had a granulomatous injury pattern. Electron microscopic study of liver tissue done in two patients showed phospholipid-laden lysosomal lamellar bodies. These findings suggest that both toxic and hypersensitivity liver injury can occur in response to amiodarone. The presence of phospholipid-laden lysosomal lamellar bodies may help differentiate amiodarone hepatotoxicity from alcoholic liver disease or other causes of hepatic steatosis.

In the past 10 years we have examined 20 children with inflammatory liver disease associated with high serum titers of anti-liver-kidney microsome antibody (anti-LKM). The first hepatic symptoms were progressive fatigue and jaundice, the fortuitous finding of hepatomegaly or splenomegaly with raised transaminase activity, or an acute hepatitis-like illness. At the time of diagnosis, hepatomegaly was present in 18 children, splenomegaly in 16, jaundice in nine, and ascites in two. Serum alanine transferase activities were elevated in all but two, who had already received steroids. Serum total gammaglobulin values were greater than 2.0 gm/dl in 16 children, prothrombin activity less than or equal to 60% in six, and serum titer of anti-LKM between 1:100 and 1:100,000. All children but one had cirrhosis, and histologic signs of aggressivity were present in 14. In 11 children one or more extrahepatic diseases were present, including type 1 diabetes, vitiligo, glomerulonephritis, autoimmune hemolytic anemia, hypoglycemia with hyperinsulinism, autoimmune thyroiditis, chronic mucocutaneous candidiasis with hypoparathyroidism, and multiple cutaneous and visceral telangiectasias. Treatment with prednisone and azathioprine improved the liver condition in 16 of the 18 patients given treatment. In eight of them discontinuation of treatment resulted in rapid relapse; 14 are still receiving treatment and have stable hepatic function with follow-up from 8 months to 6 1/2 years. Only two are free of treatment. Four children died, two in spite of immunosuppressive therapy, one during a relapse, and one of extrahepatic disease. These results indicate that this autoimmune inflammatory liver disease may have onset early in life, with several clinical patterns; is frequently associated with certain types of extrahepatic manifestations of autoimmune origin; and is a potentially fatal disease for which immunosuppressive treatment must be started early.
