ACVIM abstract presentations- the winners are:

First Place, Oral Abstract Category – Blake Guard.

Blake Guard is a Master’s student at the Gastrointestinal Laboratory, Texas A&M University. His presentation, entitled “The effect of the probiotic Sivoy on fecal microbial composition in healthy dogs”, describes changes over time in the structure of the fecal microbiome in healthy dogs receiving a high-dose probiotic product, showing a marked increase in Streptococcus spp and Bifidobacterium spp abundance after 60 days of treatment with this product.

Equal Second Place, Oral Abstract Category – A three-way tie: Dr’s Alexandra Hamilton, Yasushi Minamoto, and Sara Wennogle (alphabetical order).

Dr Alexandra Hamilton is a third year small animal internal medicine resident at Veterinary Specialty Hospital in San Diego, California. Her presentation was titled “Serum markers of Vitamin B metabolism in cats with hepatic lipidosis”. Dr Hamilton reported that cats with hepatic lipidosis had higher serum methylmalonic acid concentrations than healthy cats, even though serum cobalamin was considered normal in most affected cats. This suggests that cobalamin metabolism may be compromised at a cellular level in cats with hepatic lipidosis.  Dr Hamilton’s presentation was also judged the winner of the ACVIM Resident Award for an oral presentation in Small Animal Gastroenterology.

Dr Yasushi Minamoto is a PhD student in the Gastrointestinal Laboratory at Texas A&M University. His presentation, “Fecal short-chain fatty acid concentrations in dogs with chronic enteropathy”, demonstrated several interesting and important changes in fecal SCFA’s, and by implication changes in enterocyte metabolism, in dogs with chronic enteropathic disease. Fecal concentrations of acetate, propionate and total SCFA were all reduced in dogs with chronic enteropathy. The possible role of the gastrointestinal microbiota in these changes is an obvious area of further interest.

Dr Sara Wennogle is a resident in Small Animal Internal Medicine at Colorado State University. In her presentation “Measurement of plasma fibrinogen in dogs with hepatobiliary disease” she presented data showing that dogs with hypofibrinogenemia is more likely to occur in dogs with chronic hepatitis than with other histological categories of chronic hepatobiliary disease, with many dogs in the chronic hepatitis group showing fibrinogen concentrations lower than the assay reference range.

First Place, Poster Abstract Category – Jess Rigling

Jess Rigling is a second year veterinary student in the Oregon State University College of Veterinary Medicine. Her poster, entitled “Validation of a urinary 5-hydroxyindole acetic acid assay, and preliminary use in dogs with chronic enteropathies”, was the product of a summer research program funded by a grant from the Comparative Gastroenterology Society as part of a program to enhance DVM student interest in gastrointestinal research. In her poster, Jess showed that a commercially available assay kit for 5-HIAA, a terminal metabolite of serotonin, is usable with canine-origin urine samples following dilution to eliminate a matrix effect, and that 5-HIAA is elevated in dogs with chronic enteropathy. Interestingly, she also showed that urinary 5-HIAA:Creatinine correlates linearly with disease severity as measured by CIBDAI.

Second Place, Poster Abstract Category – Dr Frances Hurrell

Dr Frances Hurrell is a third-year small animal internal medicine at the Ryan Hospital for Companion Animals, University of Pennsylvania. Her poster, entitled “Beta-hydroxybutyrate concentrations in dogs with acute pancreatitis and without diabetes mellitus”, presented fascinating data regarding the presence of ketosis in dog with acute pancreatitis, who showed significantly higher concentrations of BOHB than either healthy dogs or sick dogs presented for diseases other than pancreatitis. In this study there was no apparent relationship between BOHB concentrations and length of clinical signs, dog’s body condition or any of several clinical pathology variables assessed, thus the prognostic utility of this finding requires further assessment.
