Overview of Canine Lymphocytic Plasmacytic Enteritis
Lymphocytic plasmacytic enteritis (LPE) is a form of inflammatory bowel disease characterized by the presence of particular microscopic cells, including lymphocytes and plasma cells, in excess within the intestinal wall in a dog.
Causes of Lymphocytic Plasmacytic Enteritis in Dogs Idiopathic, which means it has no known cause Infectious disorders such as giardia, Salmonella, Campylobactor Dietary agents such as meat proteins, food additives, preservatives, milk proteins and gluten (wheat) Genetic Factors
Lymphocytic plasmacytic enteritis is seen in both dogs and cats and is seen in all ages. It is most common in middle aged and older animal.
LPE can affect all breeds, although is seen most commonly in the German shepherd, shar-pei, and Wheaton terrier.
Although some patients with LPE may have no clinical signs, some may have life threatening manifestations. Signs vary greatly in type, severity, and frequency.
What to Watch For Diarrhea Vomiting Anorexia Ravenous appetite Lethargy Weight loss Abdominal distension Difficulty breathing Ascities, or fluid in the abdominal cavity Edema, or abnormal fluid accumulation in any part of the body Respiratory difficulty secondary to pleural effusion, which is fluid in the chest cavity
Diagnosis of Canine Lymphocytic Plasmacytic Enteritis
Diagnostic tests may include the following in your dog: Complete blood cell count (CBC) Biochemical profile Urinalysis Fecal examinations Thoracic (chest) and abdominal radiographs (X-rays) Abdominal ultrasound Gastroduodenoscopy and biopsy
Treatment for Canine Lymphocytic Plasmacytic Enteritis
Treatment of dogs with LPE should be directed at the underlying cause if identified. Most of these individuals can be treated as outpatients. Dietary management is often recommended and varies depending on the underlying cause. Fluid therapy may be necessary in some patients with severe vomiting and diarrhea, and is directed toward correction of dehydration and acid-base derangements, replacement of electrolyte deficits, and to provide for ongoing losses. Diuretics, or drugs that help remove excess fluid from the body, may be indicated in some patients with LPE. Oncotic agents are products that help maintain normal fluid distribution in the body. Anti-inflammatory drugs Antibiotic therapy
Home Care for Dogs with Lymphocytic Plasmacytic Enteritis
Administer all medication and dietary recommendations as directed by your veterinarian. Follow up as directed by your veterinarian. If your pet’s condition is not improving and is getting worse, seek veterinary attention at once.
Generally speaking, there is no preventative care for lymphocytic plasmacytic enteritis
In cases when a food intolerance or allergy is suspected or documented, avoid that particular item and adhere strictly to dietary changes.
Information In-depth on Lymphocytic Plasmacytic Enteritis in Dogs
The term lymphocytic plasmacytic enteritis (LPE) refers to the most common form of inflammatory bowel disease (IBD). It is characterized by a particular population of inflammatory cells – lymphocytes and plasma cells – that are microscopically over- represented, and that gather within the intestinal wall. Although a definitive cause has not been well established, LPE is felt to be associated with an abnormal immune response to environmental stimuli that when continued, creates a self-perpetuating inflammation resulting in the disease.
Signs associated with LPE vary greatly in type, severity, and frequency. In general, early in the disease process signs are often mild and intermittent, but they increase in severity and frequency over time. Some combination of vomiting, diarrhea, weight loss and appetite change are most often noted. Often there is an association with hypoproteinemia (low protein levels) caused by an excessive loss of protein into the gut. In animals that are hypoproteinemic, it is important to note that the initial step in the diagnosis is to exclude non-intestinal causes of hypoproteinemia, specifically related to the liver or kidneys. Many disorders must initially be considered when these individuals present.
Disorders other than primary gastrointestinal diseases that cause hypoproteinemia: Severe liver disease must be ruled out as a contributing cause of hypoproteinemia: Hepatitis (inflammation of the liver), cancer, and cirrhosis (end stage liver disease). Protein losing kidney disorders need to be considered in hypoproteinemic patients: Glomerulonephritis (inflammation of a part of the kidney) or amyloidosis, which is the deposition or collection of a type of protein in organs and tissues that compromise their normal function. Blood loss for any reason will decrease the protein level. Inadequate protein intake will contribute to hypoproteinemia.
Other infiltrative inflammatory bowel conditions: Eosinophilic enteritis, granulomatous enteritis Infectious diseases such as histoplasmosis. This is a fungal infection that affects many systems, including the gastrointestinal tract. Intestinal parasitism has been associated with PLE, especially in young pups that are anemic as well (Roundworms, hookworms, whipworms, coccidia, and giardia). Bacterial infections (Giardia, Salmonella, Campylobacter). Viral Infections. Exocrine pancreatic insufficiency (EPI) is a disorder where chronic diarrhea and weight loss develop secondary to inadequate production of digestive enzymes. Intestinal lymphangiectasia, which is blockage of the lymphatics of the gastrointestinal tract. Cancer of any sort must be ruled out. Lymphosarcoma is a malignant cancer that most often presents in the form of a microscopic infiltration into the bowel, however may form mass lesions. An intussusception, or telescoping of part of the bowel into an adjacent segment of bowel, especially chronic, may cause similar signs. Chronic foreign bodies of the intestinal tract are often associated with a number of gastrointestinal signs such as diarrhea, vomiting, and weight loss. Ulcerative gastroenteritis – interruptions in the lining of the gastrointestinal tract – must be considered. It may be secondary to inflammation, drug administration, cancer or foreign bodies. Small intestinal bacterial overgrowth is characterized by an overgrowth of normal intestinal flora (bacteria) usually secondary to various gastrointestinal diseases, but occasionally as a primary entity Hemorrhagic gastroenteritis (HGE) is a dramatic, potentially fatal disorder with no one known cause. It has a predilection for small breed dogs. HGE is characterized by the sudden onset of profuse bloody diarrhea and occasional vomiting. Food allergies, gluten-induced enteropathies, which are sensitivity to a component of wheat and other grains.
