Disseminated intravascular coagulation (DIC) secondary to colic was diagnosed in 23 horses. Each horse was categorized retrospectively as to the cause of the colic based on surgical and/or necropsy findings: group 1 consisted of 14 horses with compromised intestine that required resection and anastomosis; group 2 consisted of 3 horses with nonstrangulating intestinal displacement and/or impactions; and group 3 consisted of 6 horses with colic associated with enteritis and/or colitis. Horses were considered to be affected with DIC if at least three of five hemostatic parameters were significantly abnormal: decreased antithrombin III (AT III) values, increased level of fibrin degradation products (FDP), thrombocytopenia, prolonged activated partial thromboplastin time, and prolonged prothrombin time. The most consistent hemostatic abnormalities were decreased AT III activity, increased FDP titers, and thrombocytopenia. Clotting times were more variable and did not always correlate with the presence of excessive hemorrhage. Excessive hemorrhage was present during surgery in seven horses and occurred within 1 to 12 hours after surgery in nine other horses. In addition to treatment of the primary disease, 19 horses received treatment for DIC consisting of heparin and/or plasma or fresh whole blood transfusions. Heparin alone was used in 12 horses. Heparin, in addition to fresh whole blood transfusions or fresh plasma, was administered to four horses. Three horses were treated with plasma alone. Four other horses were not treated specifically for the DIC. Eight horses (34%) survived the acute coagulopathy. Although a greater proportion of the surviving horses received heparin therapy (87.5%; 7/8) than did those that died (60%; 9/15), the difference was not statistically significant (P = 0.345).(ABSTRACT TRUNCATED AT 250 WORDS)

Colitis "X" is a sporadic diarrheal disease of horses with clinical signs of dehydration, electrolyte imbalances and "shock"-like features. Macroscopic and microscopic findings include signs of disseminated intravascular coagulation, necrosis of colonic mucosa and presence of large numbers of bacteria in the devitalized parts of the intestine. Recently published work suggests that the causative agent may be Clostridium perfringens, Type A, but the bacteria are recoverable only in the preliminary stages of the disease. Excess protein and lack of cellulose content in the diet is thought to be the trigger for the multiplication of the clostridial organisms. The pathological findings are pathognomonic, but clinically, a number of differential diagnoses have to be considered, such as intestinal accidents, salmonellosis, heavy metal intoxication and occlusive verminous arteritis.

Six foals were inoculated intrabronchially with a suspension of Corynebacterium equi. Six weeks before this challenge, three foals were vaccinated with a C. equi bacterin. Three foals were unvaccinated controls. All foals developed a severe bronchopneumonia in the inoculated lung, indicating that vaccination was not protective. Three foals (two vaccinated, one control) were killed eight to nine days after infection. One control died on day 9 with lesions of disseminated intravascular coagulation. The remaining two foals (one vaccinated, one control) were killed on day 17. C. equi was cultured in large numbers from affected lung and bronchial lymph nodes, and in smaller numbers from unaffected lung, spleen, and liver in all foals. In the 8- to 9-day-old lung lesions, the alveoli were filled with macrophages, neutrophils, and multinucleate giant cells and most contained numerous C. equi. The few foci of alveolar necrosis were associated with groups of bacteria-laden macrophages undergoing degeneration. In the lesions of 17-day duration, there was extensive parenchymal destruction with little fibrous tissue reaction. Lesions common to both groups included hyperplastic bronchiolitis, pulmonary edema, and perivascular lymphocytic cuffs and a pyogranulomatous lymphadenitis in bronchial nodes. One vaccinated foal had a microscopic pyogranulomatous colitis. The lesions in the experimentally infected foals are compared with those in naturally infected foals and discussed in terms of likely pathogenetic mechanisms involved in C. equi pneumonia in foals.

Culture for bacteria and assays for endotoxin were performed on specimens of mesenteric and peripheral venous blood from eight patients with ulcerative colitis who underwent surgery for severe uncontrolled disease. No significant bacteraemia occurred in either portal or systemic blood. Systemic endotoxaemia developed in three patients during surgery but occurred before bowel mobilisation only in the one patient whose colitis was complicated by hyposplenism. Mesenteric endotoxaemia occurred in only three patients before bowel mobilisation, but was detected during surgery in two of the three patients who developed systemic endotoxaemia. We conclude that, contrary to earlier reports, portal bacteraemia must be infrequent in ulcerative colitis. Systemic endotoxaemia does, however, occur in a significant proportion of cases during colectomy. Although in the patients studied this led to no clinical problems, it is likely to have been the precipitating factor for the syndrome of disseminated intravascular coagulation (DIC) that we have previously observed after colectomy in some of our patients with hyposplenism secondary to inflammatory bowel disease.

The course run by the disease is described in a horse which showed the symptom complex of colitis X following treatment with oxytetracycline. Disseminated intravascular coagulation was also observed in this horse. The possibility of disseminated intravascular coagulation being part of colitis X is discussed.

Colitis in systemic lupus erythematosus (SLE) poses a diagnostic challenge as clinical, radiological and laboratory findings are often non-specific. Fulminant amoebic colitis is a rare cause of death in SLE. Early diagnosis coupled with timely surgery can reduce the mortality. The demonstration of haematophagous trophozoites in the stool is diagnostic but insensitive. Early endoscopy with adequate specimen collection is an important part of the diagnosis. Serology is both sensitive and specific but can take up to 2-4 weeks for seroconversion making it less useful in a disease that takes a rapid downhill course if treated inappropriately. We report a fatal case of colitis in a patient with SLE due to invasive amoebiasis which was complicated by Salmonella bacteraemia, disseminated intravascular coagulation, acute oliguric renal failure and adult respiratory syndrome. We also reviewed the literature on the clinical features and diagnosis of fulminant amoebic colitis. Amoebic colitis, although rare, should be considered in the differential diagnosis of lupus patients with colitis.

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.

This paper reports two patients with catastrophic complications after marathon-type running not hitherto documented. The first, who collapsed with acute abdominal pains, was found at surgery to have infarction of the omentum and later, after a second laparotomy, acute oedematous pancreatitis. The second patient, who collapsed semi-comatose with hyperthermia, developed disseminated intravascular coagulation, rhabdomyolysis, renal shutdown and progressive hepatic failure. With regular dialysis, his condition stabilised but liver function continued to decline, associated with thrombosis of the portal vein. The spectrum of potentially life threatening disorders includes upper gastrointestinal bleeding, haemorrhagic colitis and rarely infarction of the bowel. The present two cases provide further support for ischaemia being a major contributor to the gastrointestinal catastrophes of marathon-type running.

An enzymatic, kinetic method for determining serum lipase activity was evaluated and compared to a standard manual method for use in dogs. The kinetic method was a commercial kit adapted for use on a tandem access clinical chemistry analyzer and utilized a series of coupled enzymatic reactions based on the hydrolysis of 1,2-diglyceride by lipase. The manual method was the Cherry-Crandall technique based on the titration of base against the acid formed by hydrolysis of an olive oil substrate by lipase. The correlation between the two methods was very good (r = 0.94). The reference range for 56 clinically healthy dogs assayed by the kinetic method was 90 to 527 U/L. Diseases associated with a greater than twofold elevation in serum lipase activity as determined by the kinetic method included pancreatitis, gastritis with liver disease, and oliguric renal failure with metabolic acidosis. In some cases, pancreatitis was seen with other clinical problems, such as gastroenteritis, diabetic ketoacidosis, duodenal mass, disseminated intravascular coagulation, and septic peritonitis. Diseases associated with serum lipase activity within the reference range or elevated less than twofold included gastritis, gastric ulcer, cholestasis, phenobarbital-induced hepatopathy, colitis, copper hepatopathy, abdominal hematoma, apocrine gland adenocarcinoma, and thrombocytopenia with pneumonia.

The case of a 20-year-old Japanese man, diagnosed as having autosomal recessive chronic granulomatous disease (CGD), who was being treated with corticosteroids for intractable unclassified colitis, is described. He died from multiple organ failure following disseminated intravascular coagulation secondary to disseminated varicella-zoster virus (VZV) infection. He was diagnosed as an index case of CGD when 2 years old, was inoculated against VZV at the age of 5 years and had had an unremarkable course for 19 years. He was admitted to hospital because of a third episode of recurrent bloody diarrhoea. Clinical remission for each episode was achieved by intravenous corticosteroid therapy. Unclassified colitis associated with CGD was diagnosed based on a colonic biopsy demonstrating characteristic macrophages with lipofuscin deposits. From a treatment viewpoint, idiopathic inflammatory bowel disease (IBD) should be differentiated from secondary IBD occurring in CGD, in which immunosuppressive drugs including corticosteroids, still the mainstay of IBD treatment, should be avoided.
