Can you, or someone else familiar, describe EPO and its effects? My understanding is that steroids directly affect the adrenal gland and therefore cortisol production. A short bit of research on EPO does not show the same.
Testing in my horse showed reduced cortisol production and inability to react to the domperidone. Test results were interpreted to say the adrenal gland’s function was impaired. Knowing the link between steroids and the adrenal gland, combined with this horse’s recent history of retirement, the theory was posited this is his problem.
Can EPO cause the same glandular effects? Or is my horse a real anomoly, with a naturally occuring condition opposite of Cushings? I don’t wish to be argumentative, really just inquisitive. Since my guy’s “diagnosis” is really a theory, I am open to gathering information on similar situations.[/QUOTE]
My understanding of EPO is that one of its most serious side effects is anemia. It can be deadly in horses, according to all the literature I’ve read. I’ve read nothing about it having the glandular effects that anabolic steroids have. In my experience your horse is not an anomoly.
Like MDEventer, I’m not trying to be argumentative, I’m just really stumped. Turf and steeplechase horses are just tossed out in the field for vacations all the time with no adverse effects. They stay on their regular feeding schedule, but exercise ends except for turnout. And yet, when I buy horses showing the behavioral symptoms of anabolic steroids they sometimes (not always) crash and crash hard. Jessi P, maybe you don’t see it because either the horses are claimed from you or you manage them very carefully (as you described), perhaps maintaining their abs
I think the anecdotal evidence we have to offer is important and worth considering.
