Forty-three patients with spontaneous bacterial peritonitis (SBP) between 1973 and 1978 were identified. Criteria for SBP included a positive ascites culture and polymorphonuclear cell concentration greater than 250 cells per mm3. Chronic liver disease was documented by varices in 91%, severe histologic fibrosis or cirrhosis in 94%, splenomegaly in 91%, and past hospitalization for liver disease in 57% of the patients. SBP was detected within 7 days of admission in 17 patients (40%) and within 35 days in 38 patients. Single organisms were isolated from 38 patients and multiple organisms from 5 patients. Twenty-six of 43 patients survived the episode of SBP, but only 13 survived the hospitalization. Analysis of the survival curve from the onset of SBP revealed a rapid death rate and a slow death rate set of patients. Rapid death (less than or equal to 7 days from SBP onset) correlated with a lack of prior hospitalization for liver disease (p less than 0.001), hepatomegaly (p less than 0.001), increased serum bilirubin (p less than 0.005), serum creatinine (p less than 0.05), and peripheral white blood cell concentrations (p less than 0.05). Survival during hospitalization was associated with prior hospitalization with liver disease (p less than 0.001) and chills during the episode of SBP (p less than 0.001). The 43 patients were divided into Group 1 patients on the basis of a serum bilirubin greater than 8 mg% and/or serum creatinine greater than 2.1 mg%; Group 2 patients had lower values. Survival was greater in Group 2 patients with advanced, relatively quiescent liver disease compared to Group 1 patients for both the episode of SBP (91 vs. 29%; p less than 0.001) and for hospitalization (50 vs. 9%; p less than 0.05). Death in Group 2 patients was related to inadequate antibiotic therapy (p less than 0.05), nonhepatic factors, and new onset of renal failure. Although SBP in the setting of severe acute liver injury has a dismal prognosis, SBP with minimal acute liver injury has a relatively good prognosis for hospital survival even with advanced chronic liver disease. Long-term survival is also possible since 4 of 9 patients with prolonged follow-up have survived 3 years.

Acute intrinsic renal failure was diagnosed in a two-year-old, male, German shepherd dog following a Vipera aspis bite. Clinical signs included depression, hypersalivation, vomiting, tachypnoea, abdominal pain, splenomegaly, oliguria with haematuria and haemolysed serum. Leucocytosis with a shift to the left, thrombocytopenia, prolonged coagulation times (activated partial thromboplastin time, prothrombin time and thrombin time), hypofibrinogenaemia, azotaemia and hyposthenuria were the most prominent laboratory abnormalities. Histopathological evaluation of the kidneys showed a discrete glomerular hypercellularity, mesangial lysis and renal tubules filled with many hyaline casts and some necrotic cells.

We report the clinical outcome of 105 essential mixed cryoglobulinemia (EMC) patients with renal involvement collected throughout 25 years in three renal Units of Milan. The median follow-up was 72 months since renal biopsy and 131 months since the clinical onset of EMC. Patient survival was 49% at 10 years after renal biopsy. Forty-two patients died primarily from cardiovascular and liver disease or infection, whereas 15 patients developed chronic renal failure. Two patients had a complete remission of the disease while 15 had a remission only of renal signs. Thirty-one patients are alive with persistent renal and extrarenal manifestations. Anti-HCV antibodies were retrospectively detected in 34 patients and were present in 85% of them. This variable was not included in the statistical evaluation. At multivariate analysis, age older than 50 years, purpura, splenomegaly, cryocrit levels higher than 10%, C3 plasma levels lower than 54 mg/dl, and serum creatinine higher than 1.5 mg/dl were independent risk factors for death or dialysis. In conclusion, several factors may influence the outcome of patients with EMC nephritis. Markers of disease activity and an impaired renal function can herald a bad prognosis. It should be stressed, however, that only a minority of patients eventually develop renal failure, probably because in the most severe cases patients die earlier.

A 67-year-old male was admitted to our hospital because of anemia, thrombocytopenia, and renal failure. On admission he showed splenomegaly and elevated serum LDH level. Bone marrow showed hypercellularity with massive infiltration of lymphoblastoid cells. He was diagnosed as having multiple myeloma (BJ-kappa, stage IIIB). He transiently responded to intensive chemotherapy (VAD, MP, IFN alpha) but relapsed with multiple subcutaneous tumors and pericardial effusion. This is a rare case that the myeloma cell invasion to pericardial space was diagnosed before his death. The level of interleukin 6 (IL-6) in pericardial effusion was 16382 pg/ml, and the myeloma cells obtained from the pericardial effusion responded to IL-6, which suggested that high level of IL-6 closely related to the proliferation of myeloma cells in this case.

The proto-oncogene Fli-1 is a member of the ets family of transcription factor genes. Its high expression in the thymus and spleen and the presence of DNA binding sites for Fli-1 in a number of lymphoid cell-specific gene suggest that Fli-1 is involved in the regulation of lymphopoiesis. Activation of the Fli-1 gene by either chromosomal translocation or viral insertion leads to Ewing's sarcoma in humans and erythroleukemia in mice, respectively. Thus, Fli-1 is normally involved in pathways involved in the regulation of cell growth and differentiation. We have generated H-2Kk-Fli-1 transgenic mice that overexpress Fli-1 in various mouse tissues, with the highest levels of Fli-1 protein in the thymus and spleen. These Fli-1 transgenic mice developed a high incidence of a progressive immunological renal disease and ultimately died of renal failure caused by tubulointerstitial nephritis and immune-complex glomerulonephritis. The incidences of renal disease correlated with the levels of Fli-1 protein in lymphoid tissues of transgenic lines. The hypergammaglobulinemia, splenomegaly, B-cell hyperplasia, accumulation of abnormal CD3+ B220+ T lymphoid cells and CD5+ B220+ B cells in peripheral lymphoid tissues, and detection of various autoantibodies in the sera of diseased Fli-1 transgenic mice suggested the involvement of an immune dysfunction in the pathogenesis of the renal disease. In addition, splenic B cells from transgenic mice exhibited increased proliferation and prolonged survival in vitro in response to mitogens. Taken together, these data suggest that overexpression or ectopic expression of Fli-1 perturbs normal lymphoid cell function and programmed cell death. Thus, H-2Kk-Fli-1 transgenic mice may serve as a murine model for autoimmune disease in humans, such as systemic lupus erythematosus.

Human ehrlichiosis is a zoonotic disease, caused by a rickettsia that infects leukocytes. It was described for the first time in the United States of America in 1986. More than 300 cases have been reported in that country. One case has been reported in Portugal, two in France and one more in a tourist coming from Mali (Africa). In Venezuela, a tropical country, where ehrlichiosis is endemic in dogs and horses, the first case of human ehrlichiosis is reported in a seventeen month old girl. She initially had symptoms compatible with a viral illness. Then she developed a rash, acute respiratory failure, hepato-splenomegaly, neurologic abnormalities, renal failure and hematologic alterations including pancytopenia and disseminated intravascular coagulation (DIC). Different diagnoses were given before it was concluded that it was a case of ehrlichiosis. She was treated with tetracycline and very soon recovered. The initial diagnosis was made using buffy coat blood smears stained with Diff Quick Stain. Indirect Immunofluorescence (IFA) test was used to detect antibodies against Ehrlichia chaffeensis (1:126) but not to other rickettsias. Also the presence of platelets with ehrlichia bodies similar to E. platys from dogs, it was demonstrated, in peripheral blood from the child. The presence of these bodies in human platelets has not been previously reported. In this case, it could not be proved that the disease was transmitted by a tick bite. The presence of ehrlichia bodies in platelets from the girl's peripheral blood is also described.

We prospectively studied 50 Vietnamese patients with blackwater fever (BWF). All patients had fever and hemoglobinuria, 40 (80%) were jaundiced, 25 (50%) had hepatomegaly, 15 (34%) had splenomegaly, and 9 (18%) had hepatosplenomegaly. Twenty-one patients (42%) had impaired renal function, with creatinine clearances of < 50 mL/min/m2; however, only four (8%) developed oliguric renal failure, three (6%) of whom required dialysis. Forty-four patients (88%) developed anemia, which was severe (hematocrit, < 20% in 32 (64%). One patient died, representing a death rate for this once-feared disease that is considerably lower than that reported by earlier investigators. BWF was associated with quinine ingestion in 28 patients (56%), glucose-6-phosphate dehydrogenase (G6PD) deficiency in 27 (54%), and concurrent malaria infection in 16 (32%). There was no statistically significant difference in the severity of BWF associated with each of these three factors, as assessed by creatinine clearance and the hematocrit value on admission and by the number of units of blood transfused. There was considerable overlap in the occurrence of G6PD deficiency, quinine ingestion, and malaria, suggesting that these factors may interact and that it may not be justifiable to regard hemoglobinuria caused by G6PD deficiency as a separate syndrome.

32 cases (21 acute severe malaria and 11 chronic malaria syndrome), who developed unusual complications and/or manifestations are reported. The acute manifestations were unexplained tachypnoea 4, pulmonary oedema 5 and shock due to multiple organ dysfunction syndrome 3, melena 2 and E coli septicaemia in one. The other features were concomitant salmonellosis 2, meningitis 1, renal failure 3, hepatorenal syndrome 2, hepatitis like illness 7, neck stiffness with normal CSF 3, urticaria and subconiunctival haemorrhage 2 each, apyrexial spell with anaemia 4, thromocytopenia 3, and hypoglycaemia 3 (two pretreatment and one while on quinine in 5% glucose drip). The chronic syndrome noted were hyperreactive malaria syndrome (Tropical splenomegaly) 3, repeated haemolysis 2, chronic simple malaria with positive parasitaemia and normal Igm levels 4, and cerebellar ataxia with tremors 3. Bone marrow in these cases was hypercullular with increase plasma cells. Liver biopsy revealed lymphocytic infiltration. There was no case with permanent neurogical deficit. All patients with pulmonary oedema and multiple organ dysfunction died but chronic syndrome patients recovered fully. Early recoginition of atypical manifestation and prompt treatment will decrease the mortality and morbidity due to malaria.

The clinical and laboratory findings observed in 150 dogs naturally infected by Leishmania infantum, from a large endemic area of southern Italy, are described. There was a gradual onset of clinical signs and the course of the disease was progressive in almost all the cases. The majority of the dogs were mongrels (43.3 per cent), male (64.7 per cent), of medium size (50.6 per cent), three to seven years old (64.7 per cent), and living outdoors (60 per cent). They showed generalised (56.7 per cent) or symmetrical (32 per cent) lymphadenomegaly; the mucous membranes of 87 of the dogs (58 per cent) were pale and moderate or severe splenomegaly was diagnosed in 80 dogs (53.3 per cent); weight loss was observed in 32 per cent of the animals. Skin abnormalities were very common, and included dry exfoliative dermatitis (56 per cent), ulcers (40 per cent) periorbital alopecia ('lunettes') (18 per cent), diffuse alopecia (14 per cent) and onychogryphosis (24 per cent). Ocular signs were observed in 24 dogs (16 per cent) including 16 cases of keratoconjunctivitis (three with keratoconjunctivitis sicca), six cases of moderate uveitis and two cases of panophthalmitis. The acute form of the disease was diagnosed in only six dogs and was characterised by fever and generalised lymphadenomegaly, and by the absence of skin lesions. Another six dogs had severe renal failure without systemic clinical signs of leishmaniasis. The most important laboratory findings were a severe or moderate increase in gammaglobulins, hypoalbuminaemia, hyperproteinemia and anaemia. Cultures or cytology tests for L infantum parasites were positive in 134 of the dogs. Following the standard procedures developed for human lymph node and bone marrow cytology tests, the leishmania density in the dogs varied from 1+ to 2+. Leishmania antibody titres were high (> 1:160) in almost all the dogs. Immunological tests for autoantibodies were positive in 25 of 53 dogs tested in the antinuclear antibody (ANA) test, in 15 of 43 dogs tested in the latex test and in five of 24 dogs tested in the Coombs test.

Psittacosis, also referred to as ornithosis, is a disease primarily of birds, which may be transmitted to humans. Psittacosis is caused by Chlamydia psittaci, an obligate intracellular parasite found worldwide. Humans are infected with C. psittaci when the organism enters the blood stream, usually through inhalation of dried excrement from diseased birds or through wound contamination with infected avian secretions. C. psittaci replicates in the liver and spleen and infects the lung and other organs hematogenously.1 The clinical manifestations of human psittacosis range from a mild respiratory infection to a severe systemic illness.1,2 Symptoms are frequently described as flu-like with fever, headache, body aches, and dry or productive cough. Sore throat, chest pain, abdominal pain, vomiting, and diarrhea are variably present. Physical findings may include a pulse-temperature dissociation, localized lung crackles, hepatomegaly, splenomegaly, and a pale macular skin rash. Chest radiographs may demonstrate lesions that are atelectatic, patchy, miliary, nodular, or consolidated in one or both lungs. White cell counts, erythrocyte sedimentation rates, and liver function tests are usually normal. In severe illness, signs and symptoms of liver dysfunction, neurological impairment, and respiratory and renal failure may be present. Since 1879 when psittacosis was recognized as a disease entity, cases have been reported in North and South America, Europe, Asia, and Australia. However, reports of psittacosis in Africa have been rare. An Ethiopian group, studying community-acquired pneumonia, published what they claimed to be the first report of psittacosis in Africa in 1994.3 The report published here is believed to be the first documented case of human psittacosis in Egypt.
