34/ FEBRUARY 2021 THE RIDER OVC Researcher Contributes to Global Paper on Equine Asthma Not long after the 2019

Havemeyer Workshop on Equine Asthma, Dr. Dorothee Bienzle, Ontario Veterinary College, con- tributed to a global collabo- rative research paper - The current understanding and future directions of Equine Asthma research. Bienzle and her team

concentrate on the host re- sponse to challenges like dusty barn air by looking at the epithelium in the lung. By the time a horse presents with severe equine asthma (= heaves) – they are look- ing at the disease close to the end stage. By taking biopsies of the epithelium in horses with heaves, they look at the genes and pro- teins that are present and ex-

pressed. Changes often in- clude: airway remodeling, inflammation and fibrosis, to name a few. “The goal would be to identify the dis- ease early during onset, which might allow the dis- ease to be reversed,” says Bienzle. Through next genera-

tion sequencing, Bienzle and her team have distin- guished differences in gene expression between asth- matic and non-asthmatic horses. They have looked at signature variants that may indicate a susceptibility to asthma. They have identi- fied a lack of certain anti-in- flammatory proteins such as CCSP. A lack of repair func-

tions has been observed in Whispering Hearts

is a non-profit organization that relies on public support and donations.

Our mandate is to provide care and

rehabilitation to abused and neglected horses. We assist community members that can no longer care for their horses in an

attempt to prevent innocent animals being subjected to auctions and slaughter.

Where the Whispers of Many Horses in need are Heard!

Equestrian (“USEF”)

horses with end stage equine asthma such as a reduced ability to produce cytokines in adequate numbers and the inability to recruit undiffer- entiated epithelial cells to repair epithelial damage. Unfortunately, at this

time there are no early pre- dictors of equine asthma. It may be possible that bouts of inflammatory airway dis- ease at a younger age could predispose horses to asthma in later years but as of yet such evidence is not avail- able. Bienzle explains the need to follow a large group of horses over their lifespan to come up with better pre- dictors. Be sure to watch the

accompanying video which includes images from an en-

Narrowing of airway indi- cates a reduced ability to pass air in and out of lung. Excess mucous secretions are a secondary sign that re- flects inflammation. Take-aways for horse

owners dealing with heaves include: early diagnostics, aggressive treatment and, most importantly, environ- mental management. Inter- vention is recommended at the first sign of a cough, es- pecially if the cough is repetitive or persistent. Bronchoalveolar

doscope procedure used prior to abronchoalveolar lavage

(lung wash).

Through use of an endo- scope, one can assess the

mucosa in the trachea and bronchi

for secretions,

blood, purulent material and look for other indicators im- pacting respiratory health.

(BAL) is the gold standard diagnostic test for asthma. Corticosteroids adminis- tered with a bronchodilator may be prescribed to help the horse recover from bouts of equine asthma but envi-

ronmental improvement is the key. The best advice is to get them out of dusty barns and into fresh air. Until the advent of

early diagnostics , the focus for equine asthma needs to be first on prevention, and second on management and environmental ment.

USEF & WEC Statement

The United States Federation

and World

Equestrian Center Ocala (“WEC”) are pleased to an- nounce that

they have

agreed to work together on a plan for WEC to host USEF sanctioned competi- tions in the future. USEF and WEC agree that it is in the best interest of the sport for them to work collabora- tively.

Formulating this plan

will require some time for both USEF and WEC to meet and consider what is best for equestrian sport and all of its stakeholders, while prioritizing horse and rider welfare and operating under the rules that govern all USEF organizers. To allow time for that

process to unfold, the USEF has withdrawn its request to the Federation Equestre In- ternationale (FEI) to declare

World Class Clinics, Sanctioned and Non Sanctioned Events, Cowgirl Weekend Camps, Obstacle Course, Extreme Cowboy and more.

the 2021 Ocala Winter Clas- sic Spectacular unsanc- tioned and therefore riders, officials and horses may compete there this winter without being sanctioned by the FEI or USEF. Assuming development of a mutually agreed upon plan, WEC has agreed not to host any other new competitions that are not authorized by USEF. The USEF recognizes WEC’s existing relationship with NSBA and that WEC will endeavor to include NSBA within such author- ized competitions. In agreeing to this in-

terim measure, the USEF considered how important it

was for its members to have abundant competition op- portunities this winter fol- lowing a period during which many events were cancelled because of Covid- 19.

The goal now shared

by both USEF and WEC is to have a plan agreed in the coming weeks and once that is achieved, the plan will be shared publicly.
