PHF

 

Last week Sunday. Wasn't sure if we would make it to take this photo
 
A couple weeks ago, I was having a tough time. I left work early on a Friday and went to the barn and just cried. I'm a hospital microbiologist and to be honest, I had reached a point where I felt overwhelmed and so villainized by social media by means of my profession.

I have been fairly isolated since March since my husband and I are essential workers. However, I made the decision that I wanted to support my friend's open show. Chili wasn't up to attending, but she had a couple of horses I could show in hand and under-saddle.

Unfortunately, about halfway through the show, I received a call from my barn that my old grey mare (the original Semi Feral Mare) seemed to have a mild colic and had gone off feed. They had given her probiotics, electrolytes, and banamine and she seemed to be much more comfortable. I made the decision that they were keeping a close eye on her and I was several hours away, so I didn't return home at that moment.

I stopped out that evening and realized there may be something more going on. Unfortunately, she had pretty profuse diarrhea, but no temperature. I called my veterinarian who suggested that if she was eating and drinking to just keep an eye on her and to give her additional electrolytes and biosponge and see how she did.


 
 Well, the following morning, she seemed bright eyed and alert, but not quite right. Still no temperature. Of course, had to make an emergency vet call on a Sunday. The vet and I puzzled together, but decided to pull an SAA (serum amyloid A). SAA is a test that can be performed stall-side and rapidly rises if there is an infectious or inflammatory process. Normal range is a value of 0-20. Donni's that morning was over 900.

Oh sugar.

The best guess at this point was Potomac Horse Fever.

Despite the lack of fever, the rest of her symptoms seemed to fit. It was a bit of difficult news to take. Donni is 25 and with Cushing's. One of the major symptoms with Potomac Horse Fever (PHF) is laminitis, which often does not respond well to treatment and management.

 
Together with my veterinary clinic and barn owner, we started a plan. Another boarder had a pair of Softride boots I could borrow, which should help support her feet and hopefully help avoid laminitis.

Daily banamine, probiotics, biosponge, electrolytes, and IV antibiotics. My vets came every day and I had a wonderful barn owner who held her for the veterinarians to give antibiotics and fluids since in my critical job, I absolutely couldn't leave work (especially since I was in the middle of an accreditation inspection).

It really was one of the first times in my life that I surrendered control and decisions of my horses to a team I had to absolutely trust. My veterinary team dutifully called the daily report to me while I was at work and for a while, her SAA kept going up each day. I was pretty distraught and frustrated. What were we looking at?

Another veterinary friend did the biggest service and helped me think through and stay the (expensive) course.

Finally on Thursday, her numbers started to improve. Progress! Last Saturday, we gave her last dose of IV antibiotics and crossed our fingers.

 
 Hard for me to imagine that two weeks ago that I really didn't know what to think or even do with this sassy miss. It's an expensive lesson in learning some of the subtle signs and symptoms of PHF. Fingers crossed, it is all smooth sailing from here on out in her recovery.

I'll do a separate post on the actual organism that causes Potomac Horse Fever.
