Background: Changes in gastrointestinal (GI) permeability and injury are caused by a breakdown of the protective gastrointestinal epithelial barrier and commonly occurs in humans, horses, and dogs following strenuous exercise. Gastrointestinal injury and increased permeability raise the risk of ulceration and translocation of intestinal bacteria causing sepsis or systemic inflammatory response syndrome (SIRS). Current methods to assess intestinal injury and permeability in dogs are either invasive, difficult to perform, or have high variability. Intestinal fatty acid binding protein (I-FABP) and diamine oxidase (DAO) are two enterocyte proteins absorbed from the epithelium with intestinal injury. Hypothesis/Objectives: We hypothesize I-FABP and DAO concentrations will be correlated with previously obtained assessments of intestinal permeability and injury. Animals: Serum was collected after various distances of a racing trial in conditioned Alaskan sled dogs. Methods: I-FABP and DAO levels will be quantified using commercially available canine-specific ELISA assays. Protein concentrations will be correlated with 5-sugar gastrointestinal permeability and severity of gastroduodenal ulceration, previously obtained by one of the authors (Davis). Results: Pending. Conclusions and Clinical Importance: This study establishes the utility of serum I-FABP and DAO in the assessment of gastrointestinal permeability and injury in dogs. Future research will continue to validate these easily quantified biomarkers and investigate their potential both as a prognostic marker as well as an assessment of therapies in diseases of gastrointestinal injury in dogs, including sepsis/SIRS, exercise, obesity, and heart disease.
