Research Updates from the Purdue University Prospective Study of Canine Gastric Dilatation-Volvulus (GDV)

October 22,1999

1999 On Saturday, October 16,1999, Dr. Larry Glickman gave a talk at the American Kennel Club Canine Health Foundation, National Parent Club Canine Health Conference, in St. Louis, Missouri. The title was Incidence and Breed-Related Risk Factors for Gastric Dilatation-Volvulus (GDV) in Dogs: The Purdue University Five-Year Prospective Study. In this talk he characterized the clinical features of GDV and showed how the incidence had increased in dogs by more than 1500% over the past 30 years. This was followed by a description of the methods used to conduct the five-year prospective study and a statement of the objectives. After presenting the results, Dr. Glickman cautioned that they were still preliminary and speculated on their significance. Finally, Dr. Glickman answered questions raised by several breed representatives. We have included the published abstract of the talk for your information.

The first official report of the Purdue Prospective Study has been accepted for publication in the Journal of the American Veterianry Medical Association. We are hoping that this will appear in press within the next 6 months. Until that time, the above abstract of the study is all we are permitted by the journal to release at this time. As soon as it is published in the Journal of the American Veterianry Medical Association, copies will be sent to all eleven of the participating breed clubs for distribution.

We are currently preparing a second manuscript for submission to a journal. This second article will describe the findings related to risk factors for GDV in individual dogs. We are also working hard to determine what specific types of foods or ingredients in commercial dog foods or table foods contribute to bloat. This will take a longer period of time to sort out given that for the more than 1600 dogs in the study, owners reported feeding at least 150 brands and types of dog foods. For each one we need to track down the content and then calculate the daily caloric intake of each food in terms of carbohydrates, fat, protein, the sources of protein, type of fat preservative, kibble or particle size, fiber type and amount, etc. This is a great challenge and we are feeling our way with help from veterinary nutritionists. As soon as we have some findings to share, we will post them on this web site.

Thanks to everyone for the continued support. We would like to take this opportunity to thank those clubs and individuals who supported this effort over the past year.

Sincerely,

Larry Glickman
