Hydrogen breath testing after oral administration of individual sugars was considered a simple test to detect malabsorption and to assess transit time, but it has also fallen out of favor.

Hypocholesterolemia may develop with fat malabsorption and is most notable in lymphangiectasia. This plasma protein is lost into the intestinal lumen together with albumin, but unlike albumin it is an antiprotease and is excreted in the feces essentially intact. In most cases of PLE, serum albumin and globulin are both low, but a low albumin alone does not exclude it; inflammatory bowel disease IBD and neoplasia are rarely associated with hyperglobulinemia as well as hypoalbuminemia.

In dogs, EPI is most commonly due to acinar atrophy; chronic pancreatitis is less common and is seen in older animals, and pancreatic hypoplasia is a rare congenital cause. However, its use is very limited because of the use of radioactive markers. Specific treatment involves lifelong supplementation of each meal with pancreatic extract.

The prognosis is worse the more severe the small-intestinal pathology. Dogs have an early socialization period, lasting from roughly 2 to 4 months of age. The diet should comprise digestible carbohydrate preferably rice, which is most digestible and high-quality protein.

Abdominal radiography is more useful when vomiting is present or palpable abnormalities are detected, but ultrasonography is an important part of the investigation of most small-intestinal diseases.

Deconjugated bile salts and hydroxy fatty acids exacerbate diarrhea by stimulating colonic secretion. Definitive diagnosis of chronic small-intestinal disease typically includes histologic examination of intestinal biopsies taken by endoscopy or at laparotomy.

The description of morphologic abnormalities can provide a baseline to evaluate response to treatment if sequential small-intestinal biopsies are possible. Liver enzymes ALT, AST may be increased as a consequence of increased intestinal permeability, allowing more antigens to reach the liver; in such cases, a bile acid stimulation test as well as ultrasonography should be performed to exclude primary liver disease.

Speciation of Campylobacter isolates by PCR allows distinction of the pathogenic C jejuni from the more common and probable commensal C upsaliensis.

Boiled white rice and potato are suitable carbohydrate sources, while fish, lamb, or chicken are often used as a protein source, depending on the dietary history.

However, a positive response to antibiotic therapy indicates that the malabsorption is related to bacteria, perhaps in how the innate immune system toll-like receptors respond to bacterial components. Intestinal lymphangiectasia causes intestinal protein loss as well as severe fat malabsorption.

The main brush border enzyme deficiency reported is a relative lactase deficiency, leading to milk intolerance in adult dogs and cats. Once obvious dietary, systemic, parasitic, and infectious causes of chronic small-intestinal diarrhea have been eliminated, the next step is differentiation of EPI from intestinal malabsorption; the diagnosis of EPI is relatively straightforward, whereas that of small-intestinal disease is more complex.

Bacteriologic culture of duodenal fluid obtained endoscopically or at laparotomy has been used to confirm a diagnosis of ARD.

Clinical signs of malabsorption are mainly the result of lack of nutrient uptake and losses in the feces. Histologic examination of intestinal biopsy specimens can identify morphologic changes in intestinal inflammation including lymphocytic-plasmacytic enteritis and eosinophilic enteritisintestinal lymphangiectasia, villous atrophy, and intestinal neoplasia.

Effective treatment of small-intestinal disease depends on the nature of the disorder, but therapy may be empirical when a specific diagnosis cannot be made. Commercial exclusion diets are not necessary to diagnose food hypersensitivity; however, they are preferred for maintenance to reduce potential dietary imbalances.

Postmucosal obstruction may be seen with lymphatic obstruction especially lymphangiectasia and vascular compromise portal hypertension, vasculitis. Lack of pancreatic enzymes maldigestion Luminal Antibiotic-responsive diarrhea, secondary small-intestinal bacterial overgrowth Bacterial activity: Historically, the xylose absorption test was used to assess intestinal function, but it was insensitive, especially in cats, and is no longer used.

The presence of fat, undigested muscle fibers, or starch in feces may provide indirect evidence for malabsorption, but these are unreliable.

Acid suppressants eg, H2-receptor blockers, such as cimetidine or ranitidine; proton pump inhibitors, such as omeprazole may be given 20 min before a meal to inhibit acid secretion and to minimize acid degradation of enzymes in the pancreatic extract, but they are expensive and their value is questionable.

Adult diet Socialization and Training The earliest training that your puppy must learn is housetraining. Lymphocytosis in a dog with diarrhea raises the suspicion of hypoadrenocorticism.

Endoscopy is minimally invasive and allows visualization of the mucosa and targeted biopsy sampling. In cases of lymphosarcoma, treatment involves an appropriate chemotherapy regimen, but response is poor in dogs and in cats with lymphoblastic forms. Other factors such as the severity, extent, and duration of a mucosal abnormality; dietary intake; and vitamin supplementation also influence these concentrations.

Vitamin supplementation may be helpful, particularly for animals with cobalamin deficiency.
