Current Breakthroughs in Equine Research

Over the past 30 years the Grayson-Jockey Club Research Foundation has funneled nearly $20 million into studies aimed at improving horse health. This year the effort continues with funding for a dozen new projects in fields ranging from laminitis to lameness diagnosis. A sampling:

Detecting lameness at the gallop: Kevin Keegan, DVM, of the University of Missouri, is developing an objective method (using a calibrated instrument) for detecting obscure, subtle lameness in horses at the gallop. The goal is a low-cost method that can be used in the field to increase understanding of lameness in racehorses.

Deworming and vaccines: While it’s not unusual to deworm and vaccinate horses on the same day, recent findings have raised concerns about possible interactions. Martin Nielsen, DVM, of the University of Kentucky and Gluck Equine Research Center, is investigating whether deworming causes an inflammatory reaction that affects vaccination.

Imaging injured tendons: Horses recovering from tendon injuries are often put back to work too soon and suffer re-injury. Sabrina Brounts, DVM, of the University of Wisconsin–Madison, is exploring a new method developed at the university to monitor healing in the superficial digital flexor tendon. The technique, called acoustoelastography, relates ultrasound wave patterns to tissue stiffness: Healthy tendon tissue is stiffer than damaged tissue.

Detecting laminitis early: Hannah Galantino-Homer, VMD, of the University of Pennsylvania, is investigating possible serum biomarkers (molecular changes in blood) that appear in the earliest stages of laminitis. The goal is to develop tests for these disease markers so that treatment can start when laminitis is just developing, before it’s fullblown and damages the foot.

Other new studies include evaluations of a rapid test for salmonella; investigation of how neurologic and non-neurologic equine herpesvirus 1 (EHV-1) spreads cell-to-cell in the body; an effort to map the distribution of stem cells after direct injection into veins; and more.

Immune Booster Leads to Infection?

For the past 6 weeks, my horse has been receiving Ozonetherapy to aid in his chronic back leg related issues- dermatitis (“scratches”), previous DDFT tendon laceration, a history of Lymphingitis, and the residual scar tissue from his DDFT injury.  Due to his age (27), he lacks proper circulation in his hind end which does not help him fight his pastern dermatitis.  


According to the American Academy of Ozonetherapy, Ozonetherapy is described as;

“Ozonotherapy is the use of medical grade ozone, a highly reactive form of pure oxygen, to create a curative response in the body. The body has the potential to renew and regenerate itself. When it becomes sick it is because this potential has been blocked. The reactive properties of ozone stimulate the body to remove many of these impediments thus allowing the body to do what it does best – heal itself.”

“Ozonotherapy has been and continues to be used in European clinics and hospitals for over fifty years. It was even used here in the United States in a limited capacity in the early part of the 20th century. There are professional medical ozonotherapy societies in over ten countries worldwide. Recently, the International Scientific Committee on Ozonotherapy (ISCO3) was formed to help establish standardized scientific principles for ozonotherapy. The president of the AAO, Frank Shallenberger, MD is a founding member of the ISCO3.”

“Ozonotherapy was introduced into the United States in the early 80’s, and has been increasingly used in recent decades. It has been found useful in various diseases;

  • It activates the immune system in infectious diseases.
  • It improves the cellular utilization of oxygen that reduces ischemia in cardiovascular diseases, and in many of the infirmities of aging.
  • It causes the release of growth factors that stimulate damaged joints and degenerative discs to regenerate.
  • It can dramatically reduce or even eliminate many cases of chronic pain through its action on pain receptors.
  • Published papers have demonstrated its healing effects on interstitial cystitis, chronic hepatitis, herpes infections, dental infections, diabetes, and macular degeneration.”

 

After doing research and speaking to one of my good friends, we determined that Chance’s flare up of Lymphingitis, after almost 3 years of not a single issue, could possibly be caused by his immune system’s response to Ozonetherapy.  Let me explain.

Chance suffers from persistent Pastern dermatitis (“scratches”) since I purchased him in 2000.  I have tried everything- antibiotics, every cream and ointment and spray for scratches, diaper rash ointment, iodine and vaseline mix, Swat, laser treatments, scrubs and shampoos, shaving the area, wrapping the area, light therapy…you name it, I have tried it.  So, when we began Ozonetherapy to help break down the left over scar tissue from his old DDFT injury, I noticed that his scratches were drying up and falling off.  We continued administering the Ozonetherapy once a week for about 6 weeks.  The improvement was dramatic!  

However, one day Chance woke up with severe swelling in his left hind leg and obviously, he had difficulty walking.  He received Prevacox and was stall bound for 24 hours.  The vet was called and she arranged to come out the following day.  The next morning, Chance’s left leg was still huge and he was having trouble putting weight on it.  I did the typical leg treatments- icing, wrapping.  The swelling remained.  I tried to get him out of his stall to cold hose his leg and give him a bath but he would not budge.  He was sweaty and breathing heavily and intermittently shivering.  So, I gave him an alcohol and water sponge bath and continued to ice his back legs.   I sat with him for 4 hours waiting for the vet to arrive.  He had a fever and wasn’t interested in eating and his gut sounds were not as audible.  He was drinking, going to the bathroom, and engaging with me.  I debated giving him Banamine but did not want it to mask anything when the vet did arrive.  

The vet arrived, gave him a shot of Banamine and an antihistamine and confirmed that Chance had a fever of 102 degrees and had Lymphingitis.  There was no visible abrasion, puncture, or lump… I asked the vet to do x-rays to ensure that he did not have a break in his leg.  The x-rays confirmed that there was no break.  The vet suggested a regiment of antibiotics, steroids (I really am against using steroids due to the short-term and long-term side effects but in this case, I would try anything to make sure he was comfortable) , prevacox, and a antacid to protect Chance from stomach related issues from the medications.  It was also advised to continue to cold hose or ice and keep his legs wrapped and Chance stall bound.  

The following day, Chance’s legs were still swollen but his fever had broken.  The vet called to say that the CBC had come back and that his WBC was about 14,00o. She suggested that we stop the steroids and do the antibiotic 2x a day and add in Banamine. I asked her if she could order Baytril (a strong antibiotic that Chance has responded well to in the past) just in case.  And that is what we did.  

Being as Chance had such a strong reaction to whatever it was, I did some thinking, discussing, and researching…first and foremost, why did Chance have such an extreme flare up of Lymphingitis when he was the healthiest he has ever been?  And especially since he had not had a flare up in 3+ years…plus, his scratches were getting better not worse.  The Ozonetherapy boosted his immune system and should provide him with a stronger defense against bacteria, virus’, etc.  So why exactly was he having a flare up?  And that is when it hit me!

In the past when Chance began his regiment of Transfer Factor (an all natural immune booster), he broke out in hives.  The vet had come out and she felt it was due to the Transfer Factor causing his immune system to become “too strong” and so it began fighting without there being anything to fight, thus the hives.  My theory- Chance started the Ozonetherapy and his body began to fight off the scratches by boosting his immune system.  As the treatments continued, his immune system began to attack the scratches tenfold.  This resulted in his Lymphatic system to respond, his WBC to increase, and his body temperature to spike.  Makes sense…but what can I do to ensure this is not going to happen again?  

My friend suggested attacking the antibiotic resistant bacteria by out smarting them…okay, that seems simple enough…we researched the optimal enviroments for the 3 types of bacteria present where Chance’s scratches are (shown in the results of a past skin scape test).  The bacteria – E. Coli, pseudomonas aeruginosa and providencia Rettgeri. The literature stated that PA was commonly found in individuals with diabetes…diabetes…SUGAR!  How much sugar was in Chance’s feed?  I looked and Nutrina Safe Choice Senior feed is low in sugar…so that is not it.  What else can we find out?  The optimal temperature for all three bacteria is around 37 degrees celsius (or 98.6 degrees fahrenheit), with a pH of 7.0, and a wet environment. Okay, so, a pH of 7.0 is a neutral.  Which means if the external enviroment (the hind legs)pH is thrown off, either to an acidic or alkaline pH, the bacteria will not have the optimal enviroment to continue growing and multiplying.  How can I change the pH?  

Vinegar!  An antimicrobial and a 5% acetic acid! And…vinegar is shown to help kill mycobacteria such as drug-resistant tuberculosis and an effective way to clean produce; it is considered the fastest, safest, and more effective than the use of antibacterial soap.  Legend even says that in France during the Black Plague, four thieves were able to rob the homes of those sick with the plague and not become infected.  They were said to have purchased a potion made of garlic soaked in vinegar which protected them.  Variants of the recipe, now called “Four Thieves Vinegar” has continued to be passed down and used for hundreds of years (Hunter, R., 1894).

I went to the store, purchased distilled vinegar and a spray bottle and headed to the farm.  I cleaned his scratches and sprayed the infected areas with vinegar.  I am excited to see whether our hypothesis is correct or not…I will keep you posted!

When It Rains, It Pours

The other day I noticed that Chance’s back fetlock a were slightly swollen and he was visably stiffer then normal. I also noticed a golf ball sized lump in the middle of the his chest. It wasn’t super sensitive and looked like a tick bite reaction, except there was no tick and a tiny barely noticeable scratch. 

I put a Poltace wrap on his back right leg (which was the leg he had previously injured and received stem cell injections in) and gave him some pain medication. I also started him on Baytril and Ulcerguard as a precaution as previously advised by the vet.

I made an appointment with our vet to come ultrasound his hind right leg and she was to come out in the next two days. I was incredibly anxious to say the least.  

The vet arrived and explained that the lump on Chance’s chest was a hematoma from another horse biting him or from him hitting something. Nothing to worry about, it was just the pooling of fluids to lowest point. 

I then trotted Chance back and forth as the vet watched. After an exam and the ultrasound, the vet explained that she felt that the swelling was due to Chance’s hip pain and the Pastern dermatitis that we have been treating and we’re finally coming off. 

The ultrasound showed a tiny DDFT lesion (vet referred to as a defect that shouldn’t be causing any symptoms). The ultrasound also showed scar tissue that we need to get “stretched out” so that he can gain increased flexibility and work as a protection for Chance’s tendons and legiments. The ultrasound also showed some fluid build up as well. Chance’s Fetlock looks good as do his legiments.

The vet wants Chance to stay on Baytril and Ulcerguard until complete. She also has added a 5 day course of Benadryl and steroids to help with edema of back hind legs. 

She also provided me with a shampoo that is milder to clean off scratches and apply swat after cleaning. The vet explained that she didn’t understand why people picked the scabs from the scratches because they’re super deep and pulling the scabs off does more harm than good.  

The Vet commented on Chance’s weight gain and how great his skin looks gooded. She wants me to continue working on the scratches and continue doing physical therapy on hills to build up his hind end then get farrier out for back feet. 

All and all I feel good about how Chance is doing and feeling. He is still full of energy, eats like he hasn’t eaten in a week, and his eyes and coat are bright. He is not on daily pain medication and is only given it when he is not feeling great. Aside from a few hiccups, Chance is loving life and being spoiled!
