People infected with schistosomes may present with a variety of clinical manifestations ranging from the relatively asymptomatic intestinal (INT) form to the hepatointestinal (HI) or hepatosplenic (HS) forms characterized by hepatomegaly and hepatosplenomegaly with severe portal hypertension, respectively. Flow cytometry analyses were used to evaluate the contribution of apoptosis in specific cell populations from schistosomiasis patients to the development of the different clinical forms of the disease. The results showed that cell death induced by combinations of specific antigen and cytokines corresponds with specific clinical presentations. It was shown that soluble egg antigen (SEA) increased the level of apoptosis only in T cells from INT patients. Stimulation with soluble lung worm antigen preparation (SLAP) did not induce significant differences in the levels of apoptosis in T cells from the patients with the different clinical forms of schistosomiasis. These results suggest for the first time that apoptosis plays an important role in the modulation of the anti-SEA response in INT patients.

Acute hepatitis led to abnormal coagulopathy, bleeding, and death in a nonhemophiliac infant infected with the human immunodeficiency virus, possibly due to zidovudine or ritonavir or both. Acute hepatitis during ritonavir treatment and episodes of spontaneous bleeding have been reported in patients with hemophilia. Zidovudine is associated with elevated liver enzymes, elevated bilirubin, and hepatomegaly leading to abnormal coagulopathy, bleeding, and death in adults. A temporal relationship between the start of combination antiretroviral therapy and onset of hepatosplenomegaly and rise in liver enzymes suggests that zidovudine or ritonavir, or both, are the likely cause of this adverse event. Ritonavir is believed to cause direct hepatotoxicity, probably by inducing acute mitochondrial toxicity, and may hasten reverse transcriptase inhibitor-induced liver toxicity. Liver function of patients receiving a combination of nucleoside reverse transcriptase inhibitor and protease inhibitors should be closely monitored.

A 38-year-old man with refractory follicular lymphoma underwent allogeneic BMT from an HLA-identical sibling donor. He had generalized lymphadenopathy, hepatosplenomegaly and lymphoma infiltration of the marrow, all of which disappeared within 3 months following transplantation. Six months post-transplant, progressive hepatomegaly developed in the absence of splenomegaly and lymphadenopathy, and he died from hepatic failure. Autopsy disclosed diffuse large B cell lymphoma of the liver, into which the follicular lymphoma had transformed. Future issues to be investigated should include the optimal timing of allogeneic BMT for low-grade lymphomas.

A malaria survey was conducted to examine the presence of common clinical features of malaria in individuals living in an endemic area of malaria. The overall infection rate was 11.0% with 7.5% and 3.5% infected with Plasmodium vivax and Plasmodium falciparum respectively. The mean parasitaemia level of both species was 2905.9 parasites/microliter blood, with the mean parasitaemia level of P. vivax and P. falciparum at 682.7 parasites/microliter blood and 6981.7 parasites/microliter blood respectively. The infection rates were higher in the younger age group. Hepatomegaly, hepatosplenomegaly and clinical anaemia were significantly associated with malaria. None of the patients were febrile. In conclusion, in low endemic areas, the presence of clinical anaemia, hepatomegaly and hepatosplenomegaly in afebrile individuals could be considered as useful criteria for the presence of asymptomatic parasitaemia. It is important to carry out laboratory diagnostic investigations, to ensure all the asymptomatic parasitaemia which act as reservoirs are detected and treated.

In neonates, inborn errors of metabolism can produce all the major signs of liver dysfunction - jaundice, coagulopathy, hepatomegaly, splenomegaly, ascites and encephalopathy. The significance of encephalopathy in the neonate is different from that in older patients; it is usually due to a specific abnormality such as hypoglycaemia rather than being a non-specific indicator of liver failure. Attention is focused on five neonatal presentations: unconjugated hyperbilirubinaemia, cholestatic jaundice with otherwise good liver function, severe liver dysfunction (jaundice, coagulopathy persisting after vitamin K, and ascites), hepatomegaly with hypotonia+/- cardiomyopathy; and hepatosplenomegaly. The metabolic disorders presenting in these ways are listed alongside specific clinical features that can aid differential diagnosis and tests that can be used to confirm or refute the diagnosis. Diagnosis is important because treatment can be dramatically effective, e.g. withdrawal of galactose in galactosaemia. Even when treatment is not effective it is often possible to offer prenatal diagnosis for future pregnancies.

There has not been a reported series of children with therapy-induced myelodysplastic syndrome/acute myeloid leukemia (tMDS/tAML) who were treated systematically. This paper describes 24 children with tMDS/tAML who were assigned randomly to standard- or intensive-timing induction on protocol CCG 2891. Presenting features and outcomes of those children were compared with those of 960 patients with de novo MDS (62 patients) or AML (898 patients). Children with tMDS/tAML were older at presentation (P =.015), had lower white blood cell counts (P =.01), and were more likely to have MDS (21% vs 7%) (P =.02) and trisomy 8 (P =.06). Fewer had hepatomegaly (P =.02), splenomegaly (P =.03), hepatosplenomegaly (P =.02), or classic AML translocations [t(8;21), t(15;17), 16q22; P =.02]. They had a poorer induction rate (50% vs 72%, P =.016), overall survival (26% vs 47% at 3 years, P =.007), and event-free survival (21% vs 39% at 3 years, P =.023). Disease-free survival after achieving remission was similar (45% vs 53%, P =.868). Children with tMDS/tAML who received intensive-timing induction had better outcomes than those who received standard-timing induction (overall survival 32% vs 0%, P =.54). In this study, the latency period to development of tMDS/tAML was the same for presumed alkylator-induced as for topoisomerase-induced myeloid leukemia. The findings of this study confirm that most children with tMDS/tAML have disease resistant to current therapies. Standard-timing induction appears less effective for this population.

The long-term effect of single-dose praziquantel on morbidity and mortality from Schistosoma mansoni was investigated in surveys in 1987 and 1994 in central Sudan. Prevalence of infection dropped from 53% to 34%, and intensity of infection (> or = 400 eggs/g of faeces) from 31% to 18%. There was a reduction in hepatomegaly and hepatosplenomegaly, although splenomegaly alone was unchanged. Prevalence of periportal fibrosis decreased from 14% to 10%. Endoscopic investigation of patients with fibrosis showed a reduction in oesophageal varices from 47% to 30%. Mortality due to bleeding varices was high (community-wide, up to 11/100 infected patients with bleeding). Thus praziquantel mass treatment can be spaced to a much longer period, reducing the expense of treatment, delivery and distribution.

The most common symptoms of Gaucher disease include hepatosplenomegaly and anemia and thrombocytopenia due to hypersplenism. We describe the case of a patient with Gaucher disease who had cachexia, massive hepatomegaly, and multiple focal hepatic lesions. The clinical and radiologic findings suggested malignancy. A biopsy specimen was taken from a hepatic lesion and revealed infiltration by Gaucher cells. We discuss our findings in light of the putative increased incidence of hematologic malignancies in patients with Gaucher disease.

Autoimmune lymphoproliferative syndrome (ALPS) is a rare disease occurring in childhood. Recently, it has been shown that heritable mutations in Fas or Fas ligand genes, which regulate lymphocyte survival by triggering apoptosis of lymphocytes, are the most frequent cause of ALPS. Patients with ALPS frequently have lymphadenopathy, splenomegaly and hepatomegaly, especially at young ages. A positive result of the Direct Coomb's test, autoimmune hemolytic anemia, and idiopathic thrombocytopenic purpura are the most common features of autoimmunity in patients with ALPS. Elevated numbers and percentages (>1%) of double-negative (CD4-CD8-) T cells, and characteristic pathologic findings in lymph nodes or spleen are other important diagnostic features. In this report, we present the clinical, immunologic, and pathologic features of two children who were diagnosed with ALPS. The early recognition of ALPS in children with enlarged lymph nodes, hepatosplenomegaly, and autoimmune hematologic features has important diagnostic and prognostic value in avoiding expensive and time-consuming studies and unnecessary treatments. The ratio of CD4-CD8- T cells, immunoglobulin levels and the histopathologic features of lymph nodes should be rapidly determined in these patients in order to establish an early diagnosis and treatment.

The clinical case of one patient with fever of unknown origin, due to granulomatous hepatitis of tuberculous etiology was presented. The patient was a a 50-year-old woman, with 50 days illness characterized by chills, 39 degrees C fever and heavy diaphoresis. She had a record of seven malaria cases. She looked thin and pale at the initial physical examination. During the evolution, she developed pancytopenia, massive hepatosplenomegaly, jaundice, and anasarca. The patient underwent screening tests for infection, neoplasias, collagenosis, and granulomatous diseases. The laboratory tests showed transaminase-alkaline phosphatase dissociation, which led to the final diagnosis of tuberculosis, through the histological examination of the liver parenchyma. The specific treatment against tuberculosis caused remission of fever, ascites, and hepatomegaly and normalization of liver tests, with satisfactory clinical evolution.
