Equine Laminitis Research Open Access Project Highlights Studies Funded by the Animal Health Foundation

The Animal Health Foundation would like to share the news that laminitis research funded by the charity is now available for review by donors and potential donors through a publication grant by the British Equine Veterinary Association (BEVA) Foundation in Great Britain.

BEVA's Equine Veterinary Journal (EVJ) is giving the public open (free) access to a collection of important new research papers on equine laminitis, including studies by American and Australian researchers supported by the Animal Health Foundation.

Normally, non-subscriber access to these articles would be as much as US$40 per view, per article.

The papers include practical advice as well as the latest research.

Professor Celia Marr, BVMS, MVM, PhD, DEIM, DipECEIM, MRCVS, and editor of the EVJ explains: “In view of the growing public interest in high quality science, there is increasing demand for easy, open access to journal articles via the internet, particularly on topics such as laminitis.

"In recent years, there has been an explosion of knowledge and new thinking about this devastating condition. We have also recognized that some of the old-fashioned remedies, such as standing in cold water, have sound science behind them. I hope that horse owners who are unfortunate enough to have come across laminitis will find this new online resource valuable.”

Laminitis is an equine health crisis whose time has come. The British Equine Veterinary Association Foundation recognized the need for open access to the latest research, and responded by opening a special edition of its journal to the public. (BEVA image)
The EVJ laminitis virtual issue, comprising 15 original research articles on topics including the role of insulin, the effects of cryotherapy and the regulation of epidermal stem cells in affected horses, is available at http://onlinelibrary.wiley.com/journal/10.1001/%28ISSN%292042-3306/homepage/laminitis__recent_advances_and_future_directions.htm.

In addition, the issue contains several articles from international experts commissioned by the EVJ on important aspects of laminitis including causes, treatment, prevention and future research projects. Contributors to this special issue include world-leading equine veterinary and research experts on the subject of laminitis: James Belknap, Ray Geor, Samuel Black, James A. Orsini from the USA, Andrew van Eps, Melody De Laat, Martin Sillence and Chris Pollitt from Australia and Nicola Menzies-Gow from the UK.

Subjects covered include the present state and future of laminitis research, endocrinological aspects of the pathophysiology of equine laminitis, sepsis-related laminitis, supporting limb laminitis and progress towards effective prevention and therapy for laminitis.

The EVJ has a long history of promoting laminitis research. In 2004, the publication produced a special issue dedicated to laminitis and since that time significant numbers of articles on laminitis have been published every year.

Professor Marr concludes: “We hope that this special laminitis virtual issue will provide the rigor and quality of information that many horse owners are now seeking, to help them to understand and deal with this condition as effectively as possible.”

Secretariat's Laminitis: Where were you on October 4, 1989?

Today is the anniversary of the death of the great racehorse Secretariat. We look back on what laminitis meant then, what it means now, and what we are doing to change the picture of this terrible disease.


It was a dark day in laminitis history, and we could serenade you with all the right moving words that will tug at your heart-strings. But why not go back to that day and see how the news media reported the death of America's great racehorse? The horse who could win it all--except when he came up against laminitis.

Twenty-three years have passed since Secretariat's tragic death, which was attributed to laminitis and the need to spare the great racehorse pain. How far have we come? Horses--even rich and famous ones like Secretariat--are still euthanized because of laminitis.

We know so much more, but not enough--yet.

The Animal Health Foundation had barely begun when Secretariat's death was announced. We thought we could figure laminitis out quickly if we raised enough money. But the disease has stayed a step ahead of us. Now we know we are close, and we know that the mission can be accomplished.

Nothing makes us take stock of where we've been and where we're going like today's anniversary. And nothing inspires us to keep unraveling laminitis like the knowledge that even the great Secretariat knew its pain.

We hope you will stop what you're doing and make a donation, however small, to the Animal Health Foundation, whether in Secretariat's memory or any other horse.

Signed and numbered prints of Secretariat by renowned 
equine artist Helen Hayes of Lexington, Kentucky, 
will be awarded to all donors of $250 or more.

Help us end this terrible disease. Use the PayPal button in the right sidebar or visit our donations page to learn more how you can join the laminitis research effort.

Laminitis Research: Where Does Your Money Go? Animal Health Foundation Funds Melody de Laat’s Study of Insulin-Like Receptors in the Horse’s Foot

It’s a long, long way from Queensland, Australia to Stillwater, Oklahoma. The University of Queensland had palm trees and kangaroos. Oklahoma State has pickup trucks and cowboy hats.
 
What could  uproot a young woman and move her halfway around the world?

 
Two words: Laminitis research.


Melody de Laat was a rising star back in Queensland. She earned a PhD as part of the world-renowned Australian Equine Laminitis Research Unit. Director Chris Pollitt, BVSC, PhD instilled in her the curiosity and the drive to earn not just a doctorate, but a place in the small but significant legion of successful laminitis researchers scattered around the world. 
 
Working with Dr. Pollitt, Melody discovered that receptors designed to receive insulin-like growth factor 1 (IGF-1) may be binding to insulin instead in horses when horses have high levels of insulin.

This groundbreaking discovery may enable scientists to develop strategies to try to block IGF-1 receptors from receiving insulin and prevent the disease from occurring.

The equine foot is very dependent on glucose for metabolism, but it is not dependent on insulin to deliver that glucose. Horses have a large number of IGF-1 receptors in their feet, but no insulin receptors. Pollitt’s team theorizes that these IGF-1 receptors are being stimulated by insulin that mimics insulin-like growth factor 1 and is binding to these receptors.

When this happens, the lamina stretch, and laminitis occurs.

To continue her research, Melody accepted a post-doctoral position at Oklahoma State University College of Veterinary Medicine. Even though she has only been there a few months, she’s hard at work.



Before Melody left Australia, she accepted a challenge to explain her PhD research in plain English to an audience who knew nothing about laminitis or horses--in three minutes.

Melody’s research at Oklahoma State is funded by your donations through the Animal Health Foundation. Will her research make a difference to horses at risk for laminitis? The Animal Health Foundation believes it will. 

Here’s a brief description of the project we are funding,  with your help:
Investigation of the regulation of glucose transport and insulin signaling pathways in the insulin-induction model of laminitis
Problems associated with abnormal glucose (i.e. sugar) and insulin processes are of particular interest and concern in horses where a persistently increased level of insulin in the blood causes the development of laminitis. This condition is a relatively common one among many breeds.
The current AHF-funded project being investigated by Drs. Lacombe and de Laat at Oklahoma State University aims to investigate how glucose transport and insulin signaling are regulated in the heart, muscle and lamellar tissues (in the feet) of horses that have laminitis associated with hyperinsulinaemia. 

This will be compared to glucose and insulin regulation in the same tissues of normal horses.

Why is this important research?

1. This project will study tissues that have not been previously examined to assess the pattern of glucose metabolism during very high blood insulin levels. 

2. The work will build on the limited available data on lamellar metabolism in horses with insulin-associated laminitis by investigating new topics such as intracellular signaling and inflammatory pathways in the foot and how they relate to glucose transport.

3. Characterization of the changes in glucose transport during conditions of high insulin will provide new insights into the mechanisms of insulin resistance in horses and may facilitate the development of novel therapeutic interventions for the management of metabolic diseases in horses. 

4. Finally, better understanding of the insulin-signaling processes in the foot during increased insulin availability will improve our overall understanding of laminitis. 
This may lead to new avenues for disease treatment and prevention.  

The Animal Health Foundation is encouraged by Melody’s continued involvement in laminitis research, and in her move to the United States. We are confident that her research will yield results that will move our efforts forward and ever closer to our goal of ending this terrible disease.

Thank you for your support of the Animal Health Foundation’s laminitis research.

Equine Endocrinology Summit: The Animal Health Foundation's Laminitis Research Connection

Is laminitis research just a jumble of complicated words? Dr. Walsh helps us find out why research into equine endocrine problems is critical to understanding why, how, when and if horses get laminitis.


Dr. Don Walsh
The Animal Health Foundation's Dr Don Walsh has answered some questions about The 2012 Equine Endocrinology Summit and how the information presented relates to laminitis research. Some of the speakers at the Summit included AHF-funded researchers Melody De Laat from Oklahoma State, Nicholas Frank from Tufts and Philip Johnson from the University of Missouri.

AHF: What is The Equine Endocrinology Summit? 

Dr. Walsh: The leading scientific researchers in the field of Equine Metabolic Syndrome (EMS) gathered in Boston on September 7-8 under the direction of Dr. Nicholas Frank, Professor and Chair of the Department of Clinical Sciences in Large Animal Internal Medicine of the Cummings School of Veterinary Medicine at Tufts University. I had the privilege of attending this meeting, which was sponsored by Boehringer Ingelheim Vetmedica’s Equine Division.

AHF: Why, with all the other conferences, would this meeting be needed? 

Dr. Walsh: We met to discuss the latest research findings and to shape opinion regarding the future research most needed to prevent horses from developing this type of painful laminitis. These gatherings allow for researchers who may have only known someone as a name on a manuscript to meet and interact with each other on a very informal basis. Ideas are exchanged, questions asked, friendships made, and collaborations often occur.

AHF: Did you talk only about metabolic problems? What about laminitis?

Dr. Walsh: Although Equine Metabolic Syndrome (EMS) was the main subject, some time was delegated to hearing the latest information regarding PPID (Cushing’s Disease). Both conditions are extremely relevant to laminitis, since so many affected horses develop laminitis. To understand this type of laminitis, research is exploring endocrine processes that can initiate laminitis. While EMS and PPID were the area of great interest this year, the Summit previously also covered other endocrine disorders.

AHF: What does this group hope to achieve? 

Dr. Walsh: The general direction and driving goal of the group is to find ways to diagnose both EMS and PPID earlier, before horses develop the crippling disease laminitis.

AHF: What was this meeting's most important new development relevant to the Animal Health Foundation's interest in laminitis research? 

Dr. Walsh: One of the most widely agreed upon ideas, regarding a diagnosis of EMS, was the use of an oral sugar test to reveal an abnormally large insulin and or glucose response seen in the blood measured 75 minutes after an oral dose of sugar is given. Those horses and ponies that test positive are at high risk of developing laminitis and will require special husbandry practices and in some cases drugs to maintain normal levels of insulin and normal feet. AHF is integrally involved in this research project (see upcoming article) with Dr. Nick Frank at Tufts University.

AHF: What does this mean to our horses that are at risk for EMS-type laminitis? 

Dr. Walsh: I can imagine that, in the near future, we might include an oral sugar test as part of the annual physical exam. It might work like this: the owner gives the horse two ounces of common household Karo syrup before the veterinarian arrives. Then the veterinarian takes a blood sample 75 minutes later to test the insulin and glucose levels. If the horse has any symptoms of PPID (Cushing’s Disease), a test for ACTH can also be done.

AHF: How does that relate to laminitis? 

Dr. Walsh: We know that both EMS and PPID can result in laminitis. The changes start to occur when insulin levels are elevated for a prolonged time, causing alterations in the growth pattern of the foot. This results in abnormal rings on the external hoof capsule and a separation in the hoof wall at the toe, when seen from the bottom of the foot. Early recognition and correction of the insulin level is essential to prevent laminitis. 

AHF: Did you have a favorite personal experience? 

Dr. Walsh: One of the highlights of the conference for me was meeting and enjoying a good visit with Dr. Jill Beech, who is now retired from University of Pennsylvania’s New Bolton Center. Her wisdom and experience and plain good common sense was demonstrated by her participation in many discussions during the meeting. Getting to spend some time with this great researcher was very inspiring to me. There was great planning and organization and running of the program by Dr. Nick Frank.
