Gastrointestinal diseases are a leading cause of veterinary visits, accounting for over 10% of all new cases. Now, researchers at the Texas A&M Gastrointestinal Laboratory have identified early biomarkers that can predict the risk of GI diseases in dogs before clinical symptoms appear. This groundbreaking study, published in the Journal of Veterinary Internal Medicine, could revolutionize the prevention and management of these diseases, particularly in breeds with a high mortality rate.
Certain breeds more prone to GI diseases
Soft-coated Wheaten Terriers, German Shepherds, Yorkshire Terriers, and Staffordshire Bull Terriers are among the breeds particularly susceptible to GI diseases. Soft-coated Wheaten Terriers, for example, often develop protein-losing enteropathy (PLE), a condition that can be fatal within six months of diagnosis. The ability to identify at-risk dogs before symptoms develop could significantly improve outcomes for these breeds.
Biomarkers that point to high risk of disease
Dr. Katie Tolbert, a board-certified veterinary nutritionist and small animal internist at Texas A&M, led the study. “We found that certain biomarkers start to show up before symptoms are present,” she said. “These markers include signs of inflammation, leaky gut, and other gastrointestinal changes. By identifying these early indicators, we can potentially intervene before the disease progresses.”
The research team discovered multiple biomarkers that indicate a high risk of developing GI diseases. These biomarkers can vary from dog to dog, highlighting the complexity of GI disorders. “There are all sorts of things going on in the gut that turn out to be markers for high risk,” explained Dr. Tolbert. “Any of these signs can contribute to the development of GI disease if enough changes are present.”
Subsequent study to focus on dietary interventions
With this discovery, Dr. Tolbert and her collaborators have secured funding to conduct a new study focusing on dietary interventions for Soft-coated Wheaten terriers. “As a nutritionist, I’m hopeful diet can be a benign intervention to reverse the condition in these dogs,” she said. The team aims to determine whether specific dietary changes can prevent or slow down the development of GI diseases in at-risk breeds.
New diagnostic tools for early detection
In addition to exploring dietary interventions, the GI Lab is working on developing new diagnostic tools to make pre-clinical detection more widely available. “Our goal is to create diagnostics that can identify at-risk dogs early, allowing for preventive measures to be taken,” said Dr. Tolbert.
This research holds immense promise for veterinary professionals and dog owners alike. By identifying early biomarkers and exploring dietary interventions, the study aims to improve the health and longevity of at-risk dog breeds. Veterinary professionals should stay tuned for further developments in this area, as these findings could significantly impact the management and prevention of GI diseases in clinical practice.
