The inoculation of a temperature-sensitive mutant of Salmonella typhimurium induced a long-lasting infection in susceptible (C57BL/6) and resistant (A/J) mice. During week 1 of infection, the number of bacteria in the spleens was similar in both mouse strains. Then, the decrease of bacteria was more rapid in the resistant strain. Splenomegaly and granulomatous hepatitis were more severe in the susceptible strain. The immune response induced by this infection was studied. In both mouse strains delayed-type hypersensitivity to Salmonella antigens was present, and resistance to reinfection with a virulent strain of S. typhimurium or with Listeria monocytogenes appeared with the same kinetics. Thus, it does not seem that the gene(s) controlling natural resistance to S. typhimurium act(s) on acquired immunity.

A Brucella canis infection, causing recurrent fever with so-called granulomatous hepatitis and splenomegaly, was detected serologically in a 30-year-old female patient. The disease originated in an infected dog from Greece which also showed a high titre. Following successful initial treatment with cotrimoxazole and streptomycin the disease broke out again on two further occasions. The infection was finally cured by 4-months continuous cotrimoxazole treatment after which the Brucella canis titre dropped from 1:1280 to 1:40 and then to zero. The patient has been symptom-free for the last two years.

Eosinophilic fasciitis (EF) is an acute, idiopathic inflammatory disorder often manifested by tender swelling of the extremities after extreme physical exertion. It is usually without visceral complications. I treated a 25-year-old man with EF who had reactive hepatitis and splenomegaly. To my knowledge, the former has never been reported and the latter only once.

A patient presented with recurrent upper gastrointestinal bleeding. Celiac and superior mesenteric angiography showed a superior mesenteric venous aneurysm, a normal-sized liver, an enlarged spleen, and esophageal varices. The patient gave no history of hepatitis or alcoholism. It is concluded that the portal hypertension was secondary to aneurysm of the superior mesenteric vein. Aneurysms of the portal venous system can cause chronic portal hypertension due to alteration of blood flow. We believe this to be the second case reported in the English literature of a superior mesenteric venous aneurysm.

Human infection with Schistosoma haematobium and/or Schistosoma mansoni is known to be widespread in central Liberia, but no information is available about its clinical manifestations or its significance for public health. Details of a cross-sectional morbidity study are reported. A sample from hospital out-patients and samples from 3 villages situated in areas with different transmission patterns (lack of transmission, transmission of only S. haematobium and transmission of both S. haematobium and S. mansoni) were examined. All 184 individuals were examined by standardized case history, clinical and parasitological investigations, including a skin snip for onchocerciasis and a count of schistosomal and other intestinal worm eggs from stool and urine. A complete blood count, urine analysis, urine cultures, hepatitis-B surface antigen determination and abdominal X-rays were also carried out. Schistosomal egg counts ranged from 1 to 6200/10 ml urine for S. haematobium and from 1 to 228/g stool for S. mansoni. Difficulties for the definition of accurate morbidity indices are discussed. Except for haematuria and dysuria, the overall morbidity in the study area was not striking, neither for S. haematobium nor for S. mansoni infection. No cumulative pathology was observed in patients with mixed infection. The frequency of hypertension, hepato- and splenomegaly, ascites and bacteriuria was low and no relationship to schistosomiasis could be established. Bladder calcifications were found in 10% of people living in an area of transmission of S. haematobium. Although the intensity of infection is low for both S. haematobium and S. mansoni, long-term follow-up studies are essential for a more accurate assessment of the public health importance of these parasites.

Clinical, biochemical and histological features of chronic hepatitis type B were studied in 29 children aged 8 months to 13 years. On entry into the study, all were known to have had hepatitis B surface antigen (HBsAg) with elevated serum transaminase levels for at least six months. A possible source of infection was found in 15 children. When they entered the study, all patients were anicteric and all but one asymptomatic. Hepatomegaly was detected in 15 patients and was associated with splenomegaly in two. Hypergammaglobulinemia was present in 4 children. Serological evaluation of hepatitis B virus markers showed evidence of complete viral replication (HBeAg positivity) in 24 cases and incomplete replication (anti-HBeAg positivity) in 5. Liver histology showed chronic persistent hepatitis (CPH) in 18 children, and chronic aggressive hepatitis (CAH) in 10 (3 moderately active and 7 with major signs of aggressivity ) associated with cirrhosis in 5. One patient had only minimal histological changes. Evaluation of clinical, biochemical and virological parameters did not strictly parallel the histological diagnosis in terms of "activity" of the disease. Follow-up for a mean period of 13 months showed good clinical tolerance to the disease in both CPH and CAH patients. Only 2 children with CAH were given corticosteroids and/or azathioprine for a short period. During follow-up no children with active disease developed liver insufficiency or evidence of portal hypertension. No significant difference in the percentage of children who had seroconversion to antiHBe was found between CPH and CAH groups. Only one child with CAH became HBsAg negative.(ABSTRACT TRUNCATED AT 250 WORDS)

A syndrome of acquired immunodeficiency has been identified in a group of rhesus monkeys (Macaca mulatta) which died at the California Primate Research Center. Clinical evaluation of these animals revealed that 50% or more had lymphadenopathy, weight loss, and diarrhea. At least 30% had splenomegaly, fever, cutaneous abscesses and/or arthritis/myositis. Two animals had fibrosarcomas. Anemia was seen in 19 animals, lymphopenia in 14, granulocytopenia in four and thrombocytopenia in three. Hepatitis was diagnosed histopathologically in 13. Electrophoresis revealed hypoproteinemia, hypoalbuminemia and hypogammaglobulinemia. Numerous bacterial, protozoal, and viral agents were identified including cytomegalovirus and leukocyte-associated herpesvirus. Pathologic lesions included severe post-reactive depletion of lymphocytes in germinal centers and paracortical regions of lymph nodes. Clinical and pathologic changes indicate an acquired immunodeficiency syndrome which has some similarities to AIDS in humans. This disease in monkeys may provide a model for studying that disease.

To investigate the cause of clinically detectable splenomegaly, which is common in patients receiving regular haemodialysis, splenic volume was assessed by isotopic scanning using intravenously injected technetium-99m microspheres in 34 controls and 149 patients with chronic renal failure. Of the patients, 16 had never received dialysis, 10 were undergoing continuous peritoneal dialysis, 94 were undergoing regular haemodialysis, and 29 had undergone successful renal transplantation more than nine months previously. Mean splenic volume was increased only in the patients who were receiving haemodialysis. Splenic enlargement was probably not due to iron overload as it occurred in all patients who had received haemodialysis, 14 of whom had not received intravenous iron. No patient had had hepatitis. Splenic enlargement was probably related to the process of haemodialysis itself and may have been due either to red cell damage produced by haemodialysis or to an immunological reaction induced by a component of haemodialysis, possibly ethylene oxide.

We compared light pen (LPEN) and Region of Interest (ROI) computer methods in determining spleen-to-liver (S/L) ratios both in anterior and posterior images in various liver diseases. The S/L ratio was independent of age or type of colloid used (equal particle size provided). Results with corresponding LPEN and ROI programs did not differ significantly from each other. The sensitivity and specificity were tested and the anterior view yielded somewhat better results than the posterior view but the best results were obtained when both projections were used. The sensitivity for all liver diseases was 60% and the corresponding specificity 93%. In hepatocellular diseases the sensitivity was 80-100%, but the S/L ration had only 37% sensitivity for hepatic metastases. Hepatomegaly in the anterior view was found in 67% of fatty liver cases, in 25% of cirrhosis cases, in 20% of hepatitis and in 25% of metastatic livers. Splenomegaly was noted in 39-54% of patients with hepatocellular diseases but only in 4-10% of metastatic diseases.

Previous reports have suggested that idiopathic portal hypertension, a condition quite distinct from tropical splenomegaly syndrome, occurs in Kenya. In the present study patients with oesophageal varices were allocated to diagnostic groups on the basis of liver histology and results of splenoportovenography , and these groups were then compared for prevalence of hepatitis B markers, immunoglobulin levels and results of enzyme-linked immunosorbant assay (ELISA) for S. mansoni infection. 85 patients with oesophageal varices were studied. 29.4% had histological evidence of Schistosoma mansoni infection, 20% had cirrhosis and in 25.9% liver histology was non-diagnostic and the portal vein was radiologically shown to be patent. A comparison of clinical findings, serological data and parasitological investigations suggested that this latter group was a distinct one, and did no result from failure of histological diagnosis of cirrhosis or schistosomiasis. It is likely that these patients had idiopathic portal hypertension. In 82 normal controls, the carrier rate of hepatitis B surface antigen (HBsAg) was 12.2%, 59.8% had antibody to HBsAg (anti-HBs) and 7.3% showed antibody to core antigen (anti-HBc) as the only viral marker. 58.3% of the cirrhotics and 26.7% of patients with probable idiopathic portal hypertension were HbsAg positive. The implications of these results, and limited data on hepatitis Be antigen and antibody are discussed.
