Veterinarian Karen Dye explains two canine intestinal disorders: hemorrhagic gastroenteritis and inflammatory bowel disease. The symptoms of intestinal disease are nonspecific, but characteristics such as breed, as well as blood tests of metrics such as packed cell volume, help the veterinarian pinpoint the cause, Dr. Dye writes. The recommended treatment varies depending on the diagnosis but usually includes fluids, medications and dietary changes<\/em><\/strong>. The Culpeper Star-Exponent (Va.)<\/a><\/p>\n

Q: What is HGE?<\/p>\n

Hemorrhagic Gastroenteritis (or HGE) is a serious and potentially fatal disease of the intestinal tract.\u00a0 The cause is unknown, and this condition occurs most commonly in smaller breed dogs, although it can arise in any breed. The onset of bloody diarrhea is quick and dehydration occurs rapidly. Vomiting also commonly occurs. If not treated promptly, the dog may go into shock.<\/p>\n

No specific tests are available to diagnose HGE, however, a packed cell volume (PCV) being elevated along with clinical signs and physical exam lead to a diagnosis. A normal PCV for a healthy dog would be 37-55%, meaning 37-55% of the blood volume should be red blood cells (the rest being fluid and white blood cells). When a patient becomes very dehydrated, there is less fluid in the blood stream, and the result is a rising percentage of red blood cells.\u00a0 A dog with HGE will have a PCV greater than 60%. Measurement of total protein is often done with a PCV.<\/p>\n

Dogs with HGE will have a lower than normal total protein.<\/p>\n

During an episode of hemorrhagic gastroenteritis, the intestinal lining and intestinal blood vessels become permeable to fluid. Fluid and associated proteins leak out of the blood vessels and into the intestine.\u00a0 The blood cells are too large and stay behind.\u00a0 It is in this way that fluid is lost into the intestine, causing diarrhea and dehydration.\u00a0 The PCV rises and the total protein decreases.<\/p>\n

Treatment involves hospitalization and appropriate intravenous fluid therapy.\u00a0 Symptoms such as vomiting and nausea can be controlled with medications by injection since the patient should not receive anything by mouth for at least one day.\u00a0 A bland diet can be added slowly while continuing fluid support.\u00a0 Aggressive fluid therapy will decrease the PCV into a normal range and prevent the patient from going into shock.\u00a0 Often antibiotics are indicated as well.\u00a0 It is usual for the patient to be hospitalized for several days receiving IV fluid support.<\/p>\n

It is not contagious or genetic, and we still need further research into the cause as it remains unknown.\u00a0 Sometimes, stress or hyperactivity precedes the onset of disease.<\/p>\n

Q: What is IBD?Inflammatory Bowel Disease (IBD) is a complex set of diseases all grouped together as IBD.\u00a0 There are different types of inflammatory bowel disease and the only way to definitively diagnose it is via intestinal biopsy and histopathology. Therefore, IBD is a disease that can be difficult to diagnose since many other causes of diarrhea present similarly to IBD.\u00a0 Inflammatory bowel diseases are the most common cause of long-term vomiting and diarrhea in dogs and cats.\u00a0 The cause of IBD is not completely understood.\u00a0 The gastrointestinal tract becomes invaded by inflammatory cells, including lymphocytes, plasma cells, eosinophils, macrophages, and\/or neutrophils.\u00a0 These infiltrates cause damage to the mucosal lining of the intestines, causing diarrhea and\/or vomiting.\u00a0 It is believed that with IBD, the immune system reacts abnormally to normal bacteria in the intestines.<\/p>\n

Diagnosis is based on clinical signs (chronic diarrhea, vomiting, and weight loss) in addition to the exclusion of other diseases causing similar symptoms. Other diseases include metabolic disease, infectious disease, obstructive disorders and neoplasia.\u00a0 To confirm the diagnosis of IBD, biopsies must show histological evidence of cellular infiltrates and changes to the intestinal architecture.<\/p>\n

Dietary treatment is of utmost importance. Up to 60% of dogs and cats with IBD will benefit from a special diet prescribed by your veterinarian. Sometimes antimicrobial therapy is necessary as well as a novel diet.\u00a0 Immunosuppressive drugs such as prednisone or cyclosporine are reserved for cases that fail to respond to nutritional and antimicrobial therapy.<\/p>\n

There is no cure for inflammatory bowel disease.\u00a0 It is a disease that is controlled and relapses are possible.\u00a0 Dietary compliance is important.<\/p>\n
