I was looking a a mare for breeding and found one that recovered completely from purpura haemorrhagica in 2003 that left extensive scaring on her back legs but has no effect on breeding. (She had a healthy colt in 2005)

My question is what is purpura haemorrhagica, is there any reason I should avoid this mare as a potential broodmare? She has great lines, but I know absolutly nothing about this disease.

Thanks for help

SS,

:-). I had a gelding with purpura several months ago. VERY frightening.
Regardless, talk with your vet. What you need to ask the owners of this mare is what brought on the PH.

To summarize what PH is, I cut/paste this for you (it's hard to explain)...
***immune-mediated disease called purpura hemorrhagica following infection with or vaccination from strangles. Purpura hemorrhagica is an immune-mediated vasculitis caused by deposition of immune complexes in the blood vessel walls. This causes edema and hemorrhage of the head, limbs, and/or trunk. The severity of clinical signs varies from a mild, transient reaction to a severe, fatal disease. Severe edema may result in oozing from the skin surfaces and sloughing of the skin may occur. Corticosteroids are the primary treatment for purpura......

The above is not the ONLY way a horse can get purpura, but it is by far the most common. My horse had purpura post strangles vaccination.

There is a lab called Equine Biodiagnostics that leads the field in testing...if you look them up on the web, you will find the site. They are also quite helpful over the phone for questions, etc.

Anyway, purpura is more of a condition (vs. disease), and horses can and do (like mine) recover. It is the body reacting...and purpura is the symptom.

On that note, my horse is absolutely fine. I caught the initial symptoms quickly and my vet and the university collaborated with his treatment. The ONLY recommendation in the future, is to test his serum titer levels via the SEM Elisa test to determine his risk level to strangles, and if vaccination is warranted.

Hope this helps,
Heather

I was told back in Jan that my 4yr old twh mare has Purpura Haemorrhagica. She started doing alot better and just yesterday she got bad again both hind legs are swollen and oozing again her legs swelled so bad her skin split in three places on her hind legs (fetlock) I am very worried again and very tired Coul this be caused by hosing her legs down with cold water or too much protein? both times she got bad she had increased protein i put a protein tub in the field and the second time I increased her protein with a higher fat and slightly higher protein I thought I did it slow enough Also both times this happened Ihosed her legs down from the mud the day before. Is there something else I could do for her I love her and I don't want to give up she is back on 32 mg of dexamethasone 2x,s a day bute and 15 smz 2x's a day Does sh still need trihist?
