A patient is presented in whom celiac disease was complicated by the development of chronic nongranulomatous ulcers in the small and large intestine. In addition, he had nodular lymphoid hyperplasia in the bowel wall and mesenteric lymphoadenopathy. The terminal illness was characterized by disseminated intravascular coagulation. It is postulated that the lymphoid hyperplasia was secondary to excessive stimulation of the reticuloendothelial system by nongluten antigens and may be a precursor of the development of lymphoma in celiac disease. Nongluten antigens such as bacteria or endotoxins were probably responsible for the consumptive coagulopathy.

Ten percent (214/2,059) of all dogs with cancer at North Carolina State University Veterinary Teaching Hospital had thrombocytopenia. The thrombocytopenia was associated with infectious/inflammatory etiologies in 4%, miscellaneous disorders (therapy, bone marrow failure, disseminated intravascular coagulation) in 35%, and neoplasia without identifiable secondary factors in 61% of cancer-bearing dogs. Classifying these dogs by tumor groups revealed the following proportionate ratios: lymphoid, 29%; carcinoma, 28%; sarcoma, 20%; hemic neoplasia, 7%; multiple, 5%; unclassified, 3%; benign, 3%; brain, 3%; and endocrine, 3%. Dogs with hemangiosarcoma, lymphoma, and melanoma were at increased risk of developing thrombocytopenia. Cytotoxic therapy was the major factor increasing the risk of thrombocytopenia in dogs with melanoma. Golden Retrievers were the only breed recognized with a predisposition to develop thrombocytopenia. If thrombocytopenia is identified in a dog with cancer, we recommend thorough evaluation of the coagulation system before surgery or therapy, and careful consideration of the risks and potential benefits of myelosuppressive or L-asparaginase therapy.

Still's disease is characterized by arthritis, fever, rash, lymphoid hypertrophy, leukocytosis, and anemia, often in association with thrombocytosis. We describe a patient with Still's disease and thrombocytopenia secondary to disseminated intravascular coagulation (DIC). Fifteen definite cases of DIC complicating Still's disease have been reported in the English literature. Most developed this complication while receiving high doses of salicylates in association with hepatic dysfunction. In a few, the coagulopathy has been associated with gold therapy. Our patient is only the second reported to develop DIC in the absence of drug therapy and the fourth reported to die from this complication. The clinical features of these 16 patients are summarized and proposed mechanisms of pathogenesis are reviewed.

The plasma tissue factor (TF) antigen level was measured in patients with disseminated intravascular coagulation (DIC). The plasma TF antigen was detected in normal volunteers, and it was significantly higher in DIC patients than in non-DIC patients. However, in some patients with DIC, the plasma TF antigen level was within the normal range. The plasma TF antigen level in patients with DIC significantly decreased after therapy, but it was not correlated with organ failure or outcome. The plasma TF antigen level in patients with DIC was not correlated with other hemostatic markers. The plasma TF antigen level tended to be higher in DIC patients with nonlymphoid leukemia than in those with lymphoid tumor. TF might be implicated in the occurrence and progression of DIC.

In a first experiment, 28 specific pathogen-free chickens aged 3 weeks showed clinical signs 1 to 5 days after intramuscular inoculation with Erysipelothrix rhusiopathiae. Twelve of 28 birds died 2 to 4 days after inoculation. Macroscopically, the liver, spleen and kidneys were seen to be enlarged and congested. Histologically, fibrinous thrombus formation, seen in the hepatic sinusoids, renal glomerular capillaries and small pulmonary blood vessels, was a characteristic feature. In addition, the liver showed marked congestion, increase of mononuclear cells and heterophils in the sinusoids, hyperplasia of sinusoidal lining cells, and vacuolar changes in hepatic cells. The spleen showed fibrinous exudation of the lymphoid follicles and ellipsoids with lymphocytic depletion, and hyperplasia of ellipsoidal reticular cells. There was oedema, congestion and cellular infiltration in the interstitium of the kidney. The bursa of Fabricius and thymus showed marked lymphocytic depletion. In a second experiment, the blood chemical values (uric acid, glutamic-oxalacetic transaminase, lactate dehydrogenase and gamma-glutamyl transpeptidase) of birds inoculated intramuscularly with E. rhusiopathiae were significantly higher than those of uninfected controls. The blood prothrombin times and activated partial thromboplastin times of the inoculated group were significantly greater than those of the control group. The pathological and haematological findings demonstrated that E. rhusiopathiae induced disseminated intravascular coagulation in the chickens.

A six-day-old Missouri foxtrotter colt was examined because it had had diarrhoea since it was 24 hours old. A diagnosis of colitis, septicaemia, and disruption of the arterial blood flow to the pelvic limbs was made on the basis of clinical and laboratory findings. Despite intensive medical therapy, the foal died 13 hours after being examined. Postmortem examination revealed diffuse fibrinous enteritis with lymphoid necrosis, multifocal fibrinonecrotic typhlocolitis, disseminated intravascular coagulation, and a large occluding thrombus at the aortic termination. The results of bacteriological culturing supported the diagnosis of septicaemia leading to activation of the clotting cascade, disseminated intravascular coagulation, aorto-iliac thrombosis and infarction of the pelvic limbs.

To delineate the interactions between rabbit hemorrhagic disease virus (RHDV) and host cells, organ and cellular targets of infection were identified in vivo. Viral specific antigens were detected by immunohistochemistry in liver, lung, spleen and lymph nodes cells. Also, intravascular infected cells were detected in most organs including kidneys, myocardium, thymus and central nervous system. To further characterize infected target cells, viral proteins and cell-specific surface antigens were identified simultaneously in double labeling experiments. Numerous lymphoid organ macrophages, from the splenic red pulp, circulating monocytes, alveolar macrophages and Kupffer cells were double labeled, demonstrating that cells of the mononuclear phagocyte lineage are major hosts for RHDV. Double labeling for other specific cell markers were negative. The distribution of viral antigens in these tissues coincided with those areas where cells presented morphology of apoptosis. Association of intravascular monocyte infection and apoptosis, could represent a possible mechanism to develop disseminated intravascular coagulation.

A case of nasal type natural killer (NK)/T cell lymphoma of the subcutis showing clinical and morphological features that resemble subcutaneous panniculitis-like T cell lymphoma (SPTCL) is presented. A 73-year-old man presented with swelling of the left arm and was diagnosed with panniculitis by a dermatologist. It was concluded from a skin biopsy specimen that the patient had non-Hodgkin's lymphoma of the large cell, NK/T cell type because the neoplastic cells showed polyclonal CD3 immunoreactivity. Treatment with interferon-gamma was initiated, but the patient died of disseminated intravascular coagulation and multiple organ failure 2 months after the initial symptoms appeared. However, involvement of additional organs by the lymphoma was not apparent clinically. An autopsy was not performed. A routinely stained section of the biopsy skin specimen revealed massive necrosis of the subcutaneous fat, karyorrhexis admixed with reactive histiocytes, and large atypical lymphoid cells. Immunoreactivity for polyclonal CD3 was present in the perinuclear region, but absent in the neoplastic cell membranes. CD56, CD45RO (UCHL-1), CD43 (MT1), CD45 (leukocyte common antigen), and the cytotoxic molecules perforin, granzyme B and TIA-1 were positive, but CD20 (L26), CD4, CD8, and betaF1 were negative. Epstein-Barr virus (EBV) mRNA was detected in the nuclei of neoplastic cells by in situ hybridization. Subcutaneous panniculitis-like T cell lymphoma is reported to be an EBV-negative, clonal T cell neoplasm. Although this case showed clinical and morphological features that resembled SPTCL, perinuclear polyclonal CD3 staining and membranous CD56 reactivity seen in neoplastic cells were suggestive of NK cells. Furthermore, the neoplastic cells were positive for EBV. This case is considered to be a NK/T cell lymphoma of the subcutis resembling SPTCL. It is believed that it is important to recognize such a tumor because patients may undergo a fulminant clinical course, despite the tumor being localized in the subcutaneous adipose tissue.

We compared lethal toxicity and potential for splenomegaly and disseminated intravascular coagulation (DIC) of the lipid A derivative DT-5461 with those of compound 506 (C506) and bacterial lipopolysaccharide (LPS). These agents were given intravenously, by either bolus intravenous injection (2 ml/min) or drip infusion (3 ml/4 h), into the tail vein of rats under various regimens. In naive rats, the lethal dose after bolus intravenous injection was clearly higher than that after drip infusion for C506 and LPS, but not for DT-5461. In partially hepatectomized or D-galactosamine-treated rats, a marked enhancement of the lethality was observed for all agents relative to that in naive rats. Splenomegaly was commonly seen in all surviving rats after treatment, and histopathological examination revealed lymphoid hyperplasia in the B-cell area of the white pulp zone and lympho-reticular cell proliferation of the red pulp zone. When administered intravenously by drip infusion to rats pretreated with 0.4 M lactic acid, both C506 and LPS provoked DIC. This was manifested by a decrease in platelet counts, prolongation of activated partial thromboplastin time (APTT), and an increase in fibrin-fibrinogen degradation products (FDP), with hepatocellular necrosis and glomercular fibrin thrombus formation. In contrast, DT-5461 showed no such toxic events with the same protocol. In14-day intravenous toxicity studies of DT-5461, rats were more susceptible to hepatocellular necrosis and splenomegaly than squirrel monkeys. These results demonstrate that DT-5461 is a promising compound, with antitumor activity dissociated from its toxic potential.

The influence of social disruption stress (SDR) on the susceptibility to endotoxic shock was investigated. SDR was found to increase the mortality of mice when they were challenged with the bacterial endotoxin lipopolysaccharide (LPS). Histological examination of SDR animals after LPS injection revealed widespread disseminated intravascular coagulation in the brain and lung, extensive meningitis in the brain, severe hemorrhage in the lung, necrosis in the liver, and lymphoid hyperplasia in the spleen, indicating inflammatory organ damage. In situ hybridization histochemical analysis showed that the expression of the glucocorticoid receptor mRNA was down-regulated in the brain and spleen of SDR animals while the ratio of expression of AVP/CRH-the two adrenocorticotropic hormone secretagogue, increased. After LPS injection, the expression of pro-inflammatory cytokines, IL-1beta and TNF-alpha, was found significantly higher in the lung, liver, spleen, and brain of the SDR mice as compared with the LPS-injected home cage control animals. Taken together, these results show that SDR stress increases the susceptibility to endotoxic shock and suggest that the development of glucocorticoid resistance and increased production of pro-inflammatory cytokines are the mechanisms for this behavior-induced susceptibility to endotoxic shock.
