Bone marrow lymphoblasts from 109 children admitted with untreated acute lymphoblastic leukemia (ALL) were tested for spontaneous rosette formation with sheep erythrocytes. Twenty-six children (24%) had lymphoblasts that formed rosettes (E+). Of 13 initial clinical characteristics, 8 were significantly associated with E+ lymphoblasts: mediastinal enlargement (86% of patients E+), leukocyte counts over 100 X 10(9)/liter (65% E+), nodes greater than 2 cm in any diameter (65% E+), age over 5 yr (46% E+), hemoglobin over 8 g/dl (44% E+), hepatomegaly greater than 5 cm (38% E+), boys (35% E+), and lymph node enlargement outside of the cervical area (28% E+). Spleen size, initial platelet counts, and periodic acid-Schiff scores did not distinguish E+ from E- patients. Since few patients were black and few presented with central nervous system leukemia, the association of these two characteristics with E+ blasts could not be determined. A hierarchical classification scheme and a linear logistic regression model were used to define the patterns of characteristics associated with E+ lymphoblasts. The initial clinical characteristics and the poorer course of E+ patients suggest that ALL comprises at least two biologically and clinically distinct types. The E+ ALL may result from a leukemic transformation of a non-Hodgkin lymphoma.

Forty-two with hepatosplenic patients treated with praziquantel and followed up for 5 years. One half of the patients received a single 30 mg/kg dose and the other half, two doses of 25 mg/kg given 4 hrs apart. According to Hoffman and Kato-Katz stool exams, an 83.3% cure rate, was observed after twelve months. Stool egg counts in cases of incomplete cure were greatly reduced. Liver function, as assessed by serum levels of aspartate aminotransferase, alanine aminotransferase, gamma glutamyltransferase and alkaline phosphatase activities as well as albumin and gamma globulin showed marked improvement after one year. Hepatomegaly was reduced in 81.0% of patients and splenomegaly in 78.8%. Spleen regression was complete in 15.1% of the total, and in 18.5% of those with compensated hepatosplenic disease. As a result of these observations, the authors recommend early treatment with anti-schistosomal medication, either oxamniquine or praziquantel, to halt progression of disease and reduce splenomegaly.

We previously reported that streptococcal preparation (OK-432), which is a TNF inducer, inhibits insulitis and development of autoimmune diabetes in nonobese diabetic (NOD) mice and Bio-Breeding (BB) rats, as animal models of insulin-dependent diabetes mellitus. We have recently shown that recombinant human (h)TNF-alpha also suppresses development of diabetes in NOD mice. In this study we have extended our observation on TNF to BB rats in order to see whether TNF generally inhibits autoimmune diabetes. A total of 5 x 10(4) U of rhTNF-alpha was administered i.p., twice a week to male and female BB rats from 4 to 27 wk of age. The cumulative incidence of diabetes by 27 wk of age in nontreated rats was 36.4% (8/22), whereas that in hTNF-alpha-treated rats was 0% (0/21) (p less than 0.001). The hTNF-alpha-treated rats did not lose body weight and maintained normal blood glucose concentrations. Immunologic and histologic examinations were performed at the end of the experiment. Spleen cell cytotoxicities for NK-sensitive YAC-1 and rat insulinoma (RINm5F) cells in hTNF-alpha-treated rats significantly decreased in comparison with nontreated and nondiabetic BB rats. Intensity of insulitis was also inhibited in hTNF-alpha-treated rats. Interestingly, a huge hepatomegaly and splenomegaly was found in two of the 21 hTNF-alpha-treated rats. The latter consisted of W3/13dull+ and W3/25dull+ cells, which did not exhibit cytotoxicity for either YAC-1 or RINm5F cells. These results indicate that the chronic and systemic administration of TNF has a regulatory role in autoimmune diabetes in BB rats as well as in NOD mice, and that these animals may have a defect in TNF-mediated immunoregulation.

Three study groups in the Rusizi plain (Burundi) were examined parasitologically (duplicate 28 mg Kato slides) and clinically (history, abdominal palpation) 0, 1.5, 3, 6, 12 and 24 months after treatment for Schistosoma mansoni infection. Infected subjects in Maramvya (n = 430) were treated randomly with oxamniquine 20, 30 or 40 mg/kg; those in Bulinga (n = 457) with praziquantel, 20, 30 or 40 mg/kg; those in Bulamata (n = 333) with praziquantel, 30 or 40 mg/kg. In children (less than 20 years) in Maramvya and Bulamata, infection rates and intensities returned almost to pretreatment levels one to 2 years after treatment. In Bulinga, reinfection in children was much less intense. Hardly any reinfection occurred in adults in Bulinga and Maramvya; in Bulamata, half of the cured adults were reinfected, most of them lightly, 2 years after treatment. The initial parasitological advantage of the higher dosages of both drugs disappeared generally 3-12 months after treatment. There was no indication of predisposition to heavy reinfection after treatment of subjects with initial high egg counts. Little relation between pre-treatment egg count and morbidity was observed. The impact of chemotherapy on hepatomegaly was limited and observed only in adults treated with 40 mg/kg of either drug. Spleen rates in children and adults were not affected. Abdominal pain was reduced in almost all treatment groups for 3 to 24 months. The frequency of bloody diarrhoea decreased dramatically in children and adults from all 3 villages. This effect lasted 24 months in Maramvya, 12 months in Bulinga and 6 months in Bulamata, and was not dose-dependent. It is concluded that: (i) repeated population chemotherapy combined with sanitation is necessary to achieve lasting impact on infection rates; (ii) retreatment intervals should be adapted to age group and, possibly, local endemicity levels; (iii) the morbidity impact of population chemotherapy in these conditions was greater on intestinal than on hepatosplenic disease; (iv) lower, cheaper treatment schedules may in the long term be as effective as those with high cure rates.

Three cases of a syndrome featuring massive splenomegaly, gross generalized lymphadenopathy, and moderate hepatomegaly are reported. Spleen weights ranged from 800 to 2400 g. Gradual depletion of lymphoid germinal centers, and prominent infiltration of the splenic and lymph node cords with plasma cells, immunoblasts and actively dividing B cells were the most distinctive histological features. The liver in two cases showed portal infiltrates. A marked hypergammaglobulinemia, a decrease in blood cholesterol level and hematological abnormalities related to hypersplenism were observed. The condition begins early in life and runs a chronic course, of up to 25 years. There was a family history in only one instance. Since there was no generalized immunodeficiency nor local depletion of T cells or dendritic reticulum cells, a failure in the local regulation of the immune response and possible cytokine production is postulated. This condition underlines the pivotal role of the local organization of the germinal centers in cellular cooperation and in the carrying out and regulation of the immune response.

A new disease in broiler breeders known in Australia as Big Liver and Spleen Disease (BLS) is described from field observations, retrospective record analysis, and detailed study of a selected flock. BLS has a predilection for adult birds. It is characterized clinically by a sudden drop in egg production, splenomegaly, hepatomegaly, and increased mortality and histologically by a period of lymphoproliferation followed by a period of lymphoid destruction that coincides with the clinical signs. Epidemiology suggests an infectious cause, though initial attempts at isolation of a causative agent have been unsuccessful, and it is serologically distinct from the common avian viral and mycoplasma diseases.

Measurements were made on sulfur colloid scintigrams of normal pediatric livers and spleens by analyzing 131 scans from 116 patients referred for liver or spleen trauma. Studies were used only if scans were normal, there was no history of malignancy or hepatic or splenic disease either prior to of after the study. Linear correlation was made with age, weight and both age and weight. All measured parameters correlated better with weight than with age, with vertical liver dimension exhibiting the best correlation (r = 0.848). Multivariate analysis demonstrated uniformly better correlation of all measurements with both age and weight. Spleen and liver volumes were calculated assuming simple geometry, and showed excellent correlations. Graphical presentation of data will be useful in the clinical determination of hepatomegaly or splenomegaly in routine scintigraphy.

Golden hamsters were used to determine whether intraperitoneal Zn supplementation can improve the outcome of infection with Schistosoma mansoni. The animals were divided into two groups; one received an initial intraperitoneal dose of Zn chloride (0.75 mg 100 g body wt.-1) followed by booster doses (0.25 mg 100 g body wt.-1) twice weekly for four weeks, the other group received no Zn supplement. After one week, when the initial and one booster doses were given, half of the animals in each group were exposed to S. mansoni cercariae for two hours using body immersion technique. After five weeks (one week after the final Zn supplement) the animals were killed, their worm burdens determined and their livers, kidneys, spleens, hearts and sera examined. There was a significant reduction in total worm counts in the Zn supplemented group (P less than 0.05). Also, Zn supplementation of infected animals protected them against the hepatomegaly which is very often associated with schistosomiasis. Spleen weight and Zn uptake were highest in the infected Zn supplemented group, indicating that this organ requires larger amounts of Zn to perform its various Zn-dependent immunological functions. The data suggest that Zn may enhance the ability of the body organs to resist some of the harmful effects of schistosomal infection.

A 17-year-old previously healthy high school student who lived in a dormitory was referred to our office by her private physician for evaluation of abnormal liver function tests. She was sexually active with one partner but denied any current or past substance abuse. The patient was not taking any medications or nutritional supplements. Family history was unremarkable. Physical examination revealed scleral icterus and minimal hepatomegaly. Spleen was not palpable. The liver function tests are shown in table 1. Total leucocyte count was 6.3 x 10(9)/1 with 53% lymphocytes. The platelet count was normal. Anti-Hbc IgM antibody was negative, so were anti-HAV IgM and anti-HCV antibodies. HBsAg was negative and anti-HBs antibody was positive. Erythrocyte sedimentation rate was 16 mm in the first hour. An abdominal sonogram was done to evaluate a persistent elevation in alkaline phosphatase and it showed only hepatomegaly.

Our aim was to evaluate the efficacy of abdominal US and fine-needle aspiration biopsy (FNAB) in the diagnosis of disseminated mycobacteriosis (DM) in patients with Acquired Immunodeficiency Syndrome (AIDS). We reviewed the US and clinical records of 18 AIDS patients (12 males; 22-43 years) with DM studied with abdominal US. 18 patients underwent fine-needle aspiration biopsy of enlarged abdominal lymphnodes and 11 underwent FNAB of the spleen. All aspirates were studied with acid-fast stain for fast examination and cultures for isolation of mycobacteria. Abdominal US showed: enlarged abdominal lymphnodes (diameter range: 5-35 mm; mean 17 mm) splenomegaly (spleen diameter range: 14-22 cm; mean: 16.2 cm) and hepatomegaly (right hepatic lobe thickness range: 14.5-18.5 cm) in all patients; multiple splenic abscesses (diameter range: 3-20 mm) in 11 patients; small intestine wall thickening in 5 patients (maximum bowel wall thickness range: 7-15 mm); mild to moderate ascites in 8 patients; pleural effusion in 4 patients; hyperechogenicity of the kidney cortex in 5 patients; peritoneal abscesses in one and a retroperitoneal abscess in one patient. fast-acid-stain of spleen and/or lymphnode FNAB specimens allowed early diagnosis of mycobateriosis in 18/18 cases (100%). Cultures of lymphnode aspirates grew mycobacteria in 10/18 patients (56%). Spleen aspirates grew mycobacteria in 11/11 patients (100%) Blood cultures were positive in 6/18 patients (33%). Diagnosis of species was M. tuberculosis in 9 and M. avium in 6 patients. In 3/18 patients (17%) all cultures were negative. In conclusion, abdominal US features suggest DM in AIDS patients. Spleen and/or lymphnode FNAB allows a specific diagnosis in 100% of the patients.
