Boehringer Ingelheim Launches Digital Tools to Help Veterinarians Diagnose EPM with Confidence
Updated, centralized resources include online neurological exam, interactive EPM diagnostic tool

The new website, developed by Boehringer Ingelheim and presented by Marquis® (15% w/w ponazuril) Antiprotozoal Oral Paste, aims to help veterinarians accurately identify EPM by providing updated diagnostic tools consolidated in a centralized location. undefined

Equine protozoal myeloencephalitis (EPM)—a protozoal disease that causes inflammation of the brain and/or spinal cord in horses—can be difficult to diagnose. That’s because many of the signs of EPM can vary and imitate other health issues, making it easy to overlook.

The new website, developed by Boehringer Ingelheim and presented by Marquis® (15% w/w ponazuril) Antiprotozoal Oral Paste, aims to help veterinarians accurately identify EPM by providing updated diagnostic tools consolidated in a centralized location. The site includes an online neurological exam form that can be downloaded and shared electronically and an interactive EPM diagnostic tool that walks users through a series of questions (signs, diagnostic procedures, test results) to determine the likelihood of EPM.

“As the equine veterinarian must be an expert in so many areas, the website helps provide the tools needed to provide a thorough, detailed neurological exam that can then assist the veterinarian in evaluating whether EPM is likely and more testing, such as a spinal tap, is needed,” says Sarah Reuss, VMD, DACVIM, Equine Professional Services Veterinarian for Boehringer Ingelheim.

MARQUIS IMPORTANT SAFETY INFORMATION: The safe use of MARQUIS in horses used for breeding purposes, during pregnancy, or in lactating mares has not been evaluated. In animal safety studies, loose feces, sporadic inappetence, lost weight, and moderate edema in the uterine epithelium were observed. For use in animals only. Not for human use. Keep out of reach of children.

The company worked with a team of veterinarians and researchers specializing in neurological diseases to create the site, including: Steve Reed DVM, DACVIM, Rood & Riddle Equine Hospital; Nicola Pusterla, DVM, PhD, DACVIM, UC Davis School of Veterinary Medicine; Amy Johnson, DVM, DACVIM, University of Pennsylvania School of Veterinary Medicine; Rob MacKay, BVSc, PhD, DACVIM, University of Florida College of Veterinary Medicine.

The site also includes patient-facing resources, such as the downloadable STALL Sheet, which can help the veterinarian educate horse owners about the signs of EPM—stumbling, tilted head, asymmetrical muscle loss, lameness or gait abnormality and leaning against walls.

“While performing a consistent neurological exam and EPM diagnosis are key, anything veterinarians can do to help empower horse owners to identify the signs and get the veterinarian involved sooner can ultimately help the horse as well,” Reuss says.
