Topic:Inflammatory Bowel Disease
Inflammatory Bowel Disease (IBD) in horses encompasses a group of gastrointestinal disorders characterized by chronic inflammation of the intestines. These conditions can lead to weight loss, recurrent colic, diarrhea, and malabsorption in affected horses. IBD in equines is diagnosed through clinical evaluation, laboratory tests, and often requires histopathological examination of intestinal biopsies. The exact etiology of IBD in horses remains unclear, though it is thought to involve immune-mediated processes, dietary factors, and possibly genetic predispositions. This page compiles peer-reviewed research studies and scholarly articles that explore the pathophysiology, diagnostic approaches, and management strategies for Inflammatory Bowel Disease in equine patients.
Current Topics in Medical Colic. The list of medical causes of acute or chronic colic in horses is extensive. The purpose of this article is to review 4 medical causes of equine colic with a focus on newer trends in treatment. The 4 topics selected include gastric impaction, gastric glandular disease, colon displacement, and inflammatory bowel disease.
CD3+ T-Lymphocytic Coeliac-Mesenteric Ganglioneuritis Associated with Colonic Torsion and Inflammatory Bowel Disease in an Arabian Broodmare. A 5-year-old Arabian broodmare with acute colic was diagnosed with lymphocytic ganglioneuritis of the coeliac-mesenteric ganglia and lymphocytic‒plasmacytic enterocolitis resembling inflammatory bowel disease. No significant pathogens were identified by aerobic culture or histopathological examination. The ganglia were multifocally infiltrated with small lymphocytes that were immunopositive for CD3 and negative for CD20 and CD79a antigens, indicating CD3+ T-lymphocyte-mediated coeliac-mesenteric ganglioneuritis. The findings suggest immune-mediated inflammatory bowel disease resulting in dis...
Probiotic potential of Lactobacillus isolated from horses and its therapeutic effect on DSS-induced colitis in mice. Inflammatory bowel disease (IBD) is a refractory disease that endangers both humans and animals. In recent times, Lactobacillus have been used to treat animal diseases. It may be a good choice to try to isolate Lactobacillus with probiotic potential to treat IBD. Equine, as a kind of hindgut fermentation animal has rich intestinal microflora, but data regarding this is scarce. The isolation of Lactobacillus with probiotic potential from equine may become a new method for the treatment of IBD. Four isolates of Lactobacillus were isolated from fresh feces of healthy male adult horses and analyze...
Myenteric networks of interstitial cells of Cajal are reduced in horses with inflammatory bowel disease. Inflammatory bowel disease (IBD) is a well-recognised but poorly understood disease complex in the horse. Clinical signs may vary but often include weight loss, diarrhoea and colic. The effect this disease process may have on the gastrointestinal pacemaker cells (the interstitial cells of Cajal), enteric neurons and glial cells has not been previously evaluated in the horse. Objective: To compare the density of the interstitial cells of Cajal (ICC), enteric neurons and glial cells in horses with IBD to those of normal horses using immunohistochemical markers. Methods: Retrospective, quantitati...
Diagnostics and Treatments in Chronic Diarrhea and Weight Loss in Horses. Chronic diarrhea in the horse is defined as diarrhea present for more than several days with little if any improvement. The diagnosis and treatment of horses with chronic diarrhea usually present a great challenge to the clinician. There are many limitations to treatment of these patients given the limited numbers in which a final diagnosis can be achieved. The lack of knowledge of the alterations of horse microbiota during chronic diarrhea and the multiplicity of causes also make treatment challenging. A poor prognosis is often attached to chronic diarrhea, particularly in cases with neoplasi...
Diagnostic evaluation and short-term outcome as indicators of long-term prognosis in horses with findings suggestive of inflammatory bowel disease treated with corticosteroids and anthelmintics. Recurrent colic and unexplained weight loss despite good appetite and adequate feeding and management practices are common conditions in the horse. However, little information has been published on the systematic diagnostic evaluation, response to treatment, prognostic factors or outcome of either presentation. The aims of this study were to 1) identify possible prognostic indicators and 2) report the short- and long-term response to treatment with corticosteroid therapy of a variety of horses with a presumptive diagnosis of inflammatory bowel disease (IBD). Thirty-six horses with a history of...
Evaluation of activated neutrophils in the blood of horses with colic. To evaluate the activation status of neutrophils in blood samples obtained from horses with naturally occurring colic associated with strangulating obstruction, nonstrangulating obstruction, or inflammatory bowel disease. Methods: 30 horses with naturally occurring colic and 30 healthy control horses. Methods: Activation status of neutrophils was determined by assessing the number of neutrophils that could pass through filters with 5-microm pores, cell-surface CD11-CD18 expression, and alterations in size and granularity of neutrophils. Results: Horses with impaction or gas colic did not have ...
Acute thrombosis of limb arteries in horses with sepsis: five cases (1988-1998). A hypercoagulable condition and poor perfusion to distal extremities might occur during equine endotoxaemic or septic shock, which could cause thrombosis of limb arteries. In our review, thrombosis occurred in neonatal foals in association with gram-negative bacteraemia. In 3 older foals and adults, thrombosis was associated with inflammatory bowel disease, diarrhoea and toxaemia. All patients had been treated with broad-spectrum antibiotics, nonsteroidal antiinflammatory drugs and i.v. crystalloid solutions. Two horses received i.v. hyperimmune plasma. A generalised coagulopathy was not suspe...
Inflammatory bowel disease in horses: 11 cases (1988-1998). To determine clinical and surgical abnormalities in, and long-term outcome of, horses that undergo surgery because of colic secondary to inflammatory bowel disease (IBD). Methods: Retrospective study. Methods: 11 horses. Methods: Medical records of horses that had undergone abdominal surgery and in which IBD had been diagnosed on the basis of histologic examination of intestinal biopsy specimens were reviewed. Results: 5 horses were examined because of acute colic and 6 were examined because of chronic colic. At surgery, all 11 horses had edematous or hemorrhagic bowel segments suggestive of I...
