An outbreak of chronic liver disease was investigated in a kennel of dogs. Anorexia, depression, polyuria, polydipsia, icterus and a terminal hemorrhagic diathesis were noted in clinically affected dogs. Thrombocytopenia, hypofibrinogenemia, elevated fibrinogen degradation products and prolonged activated partial thrombosplastin times (PTT) and one-stage prothrombin times (PT) were associated with the hemorrhagic crisis. Aflatoxicosis was confirmed by the presence of significant levels of aflatoxicosis was confirmed by the presence of significant levels of aflatoxin B in the commercial dog food being fed. A subacute hepatitis was found on necropsy. Disseminated intravascular coagulation was suspected as the cause of the hemorrhage in these cases and treatment was instituted.

internal abdominal abscesses in 25 horses, including 8 horses that died or were euthanatized, were found to be caused by Streptococcus equi, Streptococcus zooepidemicus, or Corynebacterium pseudotuberculosis. Breed or sex predilection was not found. Although horses of all ages were affected, those under 5 years of age were more commonly affected. Nearly all of the horses had a history of respiratory catarrh or lymphadenitis. Horses with internal abdominal abscesses also had intermittent, prolonged colic or chronic weight loss. Most horses had increased rectal temperature, increased heart and respiratory rates, and varying degrees of anorexia. Chronic depression anemia, increased plasma fibrinogen concentration, increased total plasma protein with hypergammaglobulinemia, and hypoalbuminemia were prominent clinicopathologic findings. Results of rectal examination or surgical exploration often revealed an abdominal mass. Peritoneal fluid from 14 horses was examined, and the protein content was greater than 2.5 g/dl, with increased numbers of neutrophils. Culture results were negative in all 14 cases, although bacteria were seen intracellularly in 5 cases. Long-term (2- to 6-month) antimicrobial therapy with procaine penicillin G resulted in clinical resolution in most of these animals.

Pertinent literature on naturally occurring hemorrhagic diseases in poultry and livestock were reviewed and compared with reports on recent outbreaks of a hemorrhagic syndrome in swine. Epizootiologic, clinical, and hematologic data from porcine hemorrhagic disease suggest vitamin K-responsive hypoprothrombinemia. In weanling pigs, the toxicity of warfarin was compared with that in swine given tylosin and sulfamethazine antibacterial combination versus those given warfarin only. Toxicosis was induced in weanling swine fed warfarin daily at dose level of 0.055 mg/kg of body weight. Approximately 5 days after feeding was started, signs of poisoning appeared: lameness, anorexia, subcutaneous hematomata, melena, and periarticular enlargement. Administration of warfarin at dose level of 0.017 mg/kg did not cause clinical toxicosis, and 0.028 mg/kg produced significant increases in one-stage prothrombin time (OSPT) and activated partial thromboplastin time (APTT), but no evidence of clinical bleeding. When tylosin-sulfamethazine antibacterial combination was fed at normal and high dose levels concurrently with warfarin at dose level of 0.017 mg/kg of body weight, increase of clotting time, OPST, or APTT did not occur due to antibacterial influence. The antibacterial combination fed alone did not produce changes in clotting time, OSPT, APTT, fibrinogen, total protein, differential leukocyte count, or packed cell volume.

The objective of this study was to characterize the hemostatic defect in dogs with infectious canine hepatitis (ICH), a naturally occurring viral disease of dogs. Five littermate dogs were inoculated with 10(3) TCID50 of ICH virus intravenously. Two littermates were controls. The clinicopathologic manifestations of ICH were fever, depression, anorexia, hematemesis, melena, widespread mucocutaneous petechiae, prolonged bleeding from venipunctures, faceial edema, leukopenia, and proteinuria. The hemostatic defect of ICH was characterized by thrombocytopenia, abnormal platelet function, prolonged one-stage prothrombin time and activated partial thromboplastin time, normal thrombin times, depressed factor VIII activity, and increased fibrin-fibrinogen degradation products. These findings suggested that the central pathologic mechanism of the abnormal hemostasis in ICH was disseminated intravascular coagulation (DIC). ICH is an example of DIC induced by viral infection. This disease is a suitable model for investigation of the detection, pathogenesis, and therapy of DIC.

Endotoxin, a lipopolysaccharide (LPS), is a bacterial cell wall product instrumental in producing deleterious host responses to infection. This LPS appears to act, in part, by triggering release of endogenous mediators such as cytokines. Repeated exposures to endotoxin produce attenuated responses to this molecule. To examine the mechanisms and biologic consequences of this tolerance to LPS, Wistar rats were subjected to a 14-day course of LPS administration. Tolerance to LPS with regard to anorexia, weight loss, and acute-phase responses was noted. Attenuation of these physiologic responses was accompanied by abrogation of circulating cytokine appearance in response to endotoxin, suggesting that tolerance to LPS is in part due to a decreased production of cytokines. Tolerance to LPS also diminished the response to a subsequent infected thermal injury, as measured by food intake, body weight, fibrinogen levels, and mortality. Thus, clinical conditions involving repeated exposure to LPS may modify the host's responses to subsequent injury. The attenuated responses to injury accompanying the decreased production of cytokines further implicate cytokines in the pathogenesis of injury and disease.

42 dogs with non-Hodgkin's lymphoma (NHL) were randomized for treatment with either PEG-L-asparaginase 10 IU/kg intramuscularly (n = 22) or L-asparaginase 400 IU/kg intraperitoneally (n = 20). Another 20 dogs were treated with either PEG-L-asparaginase 30 IU/kg (n = 10) or L-asparaginase 400 IU/kg (n = 10). Each treatment protocol consisted of two asparaginase treatments followed by a 10-week period of induction chemotherapy and then maintenance on asparaginase until progression occurred. No significant differences were found between treatments in the response rates after 2 weeks of asparaginase therapy or in the time to relapse, the time to treatment failure or the remission period. The reaction to asparaginase after the initial 2 weeks was a prognostic factor for the total duration of remission under asparaginase maintenance therapy. No side-effects were noted in the dogs treated with PEG-L-asparaginase, whereas 14 (48%) of the L-asparaginase treated dogs had side-effects related to this drug, including anaphylactic shock (9), anorexia or vomiting (4), hypersensitivity-related oedema (3), seizures (1) and acute pancreatitis (1). No abnormalities in clotting times, fibrinogen levels or antithrombin-III levels were found in any of the 62 dogs. PEG-L-asparaginase has the same anti-tumour activity as native L-asparaginase in dogs with NHL, but lacks side-effects.

A polyethylene glycol conjugate of L-asparaginase (PEGLA) was administered to 21 patients with refractory non-Hodgkin's lymphoma. The dose given was 2,000 mu/m2 intramuscularly every 2 weeks. Eligibility required at least one prior trial of chemotherapy and ambulatory performance status. At entry, all patients had measurable lesions and documented disease progression. The median age of the patients was 61 years; 18 (86%) were ambulatory with minimal symptoms, 12 patients (57%) had 3 or more prior regimens, and 13 (62%) had stage IV disease. Histologic subtype was low grade in 11 patients (52%), intermediate in 7 (33%), high grade in 2 (10%) and unclassifiable in one (5%). There were two partial responses (11%) noted (95% confidence interval of response of 1-30%). Eleven patients (52%) were removed from study due to disease progression. Nine patients (43%), required removal for toxicity (7 for protracted nausea and vomiting and 2 for confusion). One patient died of sepsis while on study but this was not considered drug related. Almost one third of patients complained of fatigue or loss of appetite. Nausea and vomiting occurred in approximately half the patients and was moderate to severe in 9. Diarrhea and abdominal pain were also noted in one-third of those treated. Changes in the partial thromboplastin time and fibrinogen were noted in most patients but resulted in no bleeding complications. In this trial, PEGLA displayed modest activity in a heterogenous group of patients with progressive non-Hodgkin's lymphoma.

The purpose of this study was to evaluate the effects of experimentally induced sublethal endotoxaemia in equine neonates. Four foals, between two and five days of age, were infused intravenously with 0.5 microgram/kg bodyweight of Salmonella typhimurium endotoxin (LPS) over a 5 h period. A four-day-old and a five-day-old foal, similarly infused with sterile isotonic saline, served as controls. Clinical signs were monitored, blood samples obtained for evaluation of selected haematological and biochemical parameters; and haemodynamic parameters were recorded hourly during the infusion, as well as 6 and 24 h post infusion. Depression, anorexia, increased rectal temperature, leucopenia followed by leucocytosis, hypoglycaemia, increased prothrombin time, partial thromboplastin time (APTT), pulmonary artery pressure, pulmonary artery wedge pressure, right atrial pressure, pulmonary and systemic vascular resistance and mild hypoxaemia were consistent findings in the foals receiving endotoxin. There was marked variation over time in the above parameters, during the infusion. Shock was not induced, and the foals appeared to be healthy shortly after the infusion was discontinued. The return to baseline values of body temperature (3 of 4 foals), APTT (1 of 4 foals) and neutrophil count (2 of 4 foals), during endotoxin infusion, suggests induction of early tolerance. The control foals remained alert and the temperature, prothrombin time and fibrinogen remained stable during the study. Hyperglycaemia, transient increased APTT and variations in selected haemodynamic parameters were recorded in the control foals during the infusion.

Children undergoing ABMT, a procedure which entails massive doses of chemotherapy along with total-body irradiation, are candidate to develop severe gastrointestinal toxicity and prolonged anorexia requiring administration of Parenteral Nutrition (PN) for variable periods. We report a series of 35 consecutive children affected by malignancies who underwent 37 courses of PN after ablative therapy followed by ABMT. Age ranged from 8 months to 17 years; 16 were females, 19 males. There were 23 cases of neuroblastoma, 5 of Wilms' tumor, 3 of acute myelogenous leukemia, 2 of Ewing's sarcoma, 1 case each of rhabdomyosarcoma and acute lymphoblastic leukemia. All patients developed severe neutropenia for 9-42 days (median 18 d). Fever occurred in all patients; sepsis was documented in 10. Duration of PN ranged from 10 to 64 days (23 +/- 9; mean +/- SD). PN solution, containing crystalline L-Aminoacids (8.5%) mixed with 33% glucose, minerals, trace elements and vitamins provided for children a caloric intake of 49.8 +/- 17.3 Kcal/Kg/day with a nitrogen intake of 0.26 +/- 0.27 g/Kg/day. Nutritional assessment, utilizing percent ideal body weight, serum protein electrophoresis, C3, pseudocholinesterase and fibrinogen, was performed at the beginning and at the completion of each course of PN. Mean percent ideal body weight was 95.8 before PN, 98.5 on last day of PN (p less than 0.0005). Other parameters did not change significantly. No metabolic complication nor severe electrolyte imbalance were observed except for 5 patients who developed hypokalemia in coincidence with administration of Amphotericin B.(ABSTRACT TRUNCATED AT 250 WORDS)

A 55-year-old man was admitted to our hospital with fever, ascites, generalized lymphadenopathy and hepatosplenomegaly. A cervical lymph node was biopsied and diagnosed as a diffuse mixed cell type B-cell malignant lymphoma with positive cytoplasmic IgM in plasmacytoid lymphocytes and immunoblasts. Serum protein electrophoresis disclosed a monoclonal peak and immuno-electrophoresis identified the abnormal protein as IgM kappa(k). Serum immunoquantitation revealed an IgM level of 1470 mg/dl. Bence-Jones protein of the k type was positive in the urine. Cryoglobulin with the characteristics of IgM was present in the serum. In peripheral blood, hemoglobin was 12.4 g/dl, WBC 26,500/microliters with increased abnormal cells and the platelet count 2.2 x 10(4)/microliters. Low fibrinogen and high FDP levels indicated the existence of disseminated intravascular coagulation (DIC). Gabexate mesilate (FOY) was administered at a dose of 1,000 mg/day for the DIC with very good response. After one course of combination chemotherapy (vincristine, cyclophosphamide, prednisolone, adriamycin), he achieved complete remission. However, three months later, he showed icterus and anorexia again with high levels of serum GOT and GPT and positive HBs antigen. On the 117th hospital day, he became abruptly developed right hemiplegia and coma. Cranial CT demonstrated massive thalamic bleeding in the left hemisphere with ventricular rupture, and he died on the same day.
