ACTH very high PPID (?) -- Stacey & Baron Terrace BC 2022 https://ecir.groups.io/g/CaseHistory/files/Stacey%20and%20Baron https://ecir.groups.io/g/CaseHistory/album?id=278023 |

Baron is three years old. I'm not qualified to tell you he's PPID. This level is above the Liphook seasonal rise cutoff values. No update in the CH to understand what else may be going on currently. If he were here however, I'd might be looking at testing via TRH in the spring.
Your insulin is within the reference range, and it has come down form the May report, however it is not "normal". https://www.ecirhorse.org/FastingInsulin-LabRefRanges.php -- Nancy C in NH ECIR Moderator 2003 ECIR Group Inc.

Hi Stacey, Could you please update your case history so it’s easier to compare bloodwork values? Martha in Vermont

Hi Stacey,
You need Dr Kellon's input here. Normally that would be a positive result, but for a 3 year old PPID is so unlikely.... Was there any stress that could have artificially raised ACTH, like trailering or exercise...even running around playing before the blood draw could push it up (although I would not expect that to cause it to go so high). Was blood drawn from other horses at the same barn and could there have been a sample/labeling mixup? -- Kirsten and Shaku (EMS + PPID) and Snickers (EMS) - 2019 Kitimat, BC, Canada ECIR Group Moderator Shaku's Photo Album Snickers' Case History Snickers' Photo Album |

I agree with doing a TRH stimulation after the seasonal rise.

Thank you all for responding.
Kristen, yes to all 3 questions. The vet appointment was the same as in May. Hauling to site, lunging to evaluate, blood draw. Kristen, as you are aware - until recently we have not had large animal vet service. I will check with the new vet here regarding TRH Stimulation test although that frightens me to think I could kick on a new round of laminitis!????

Hi Stacey,
I would start with getting blood drawn at home with no exercise beforehand. Given the trailering and exercise it's difficult to say if Baron is PPID or not. -- Thanks, PA 2014 https://ecir.groups.io/g/CaseHistory/files/Sherry%20and%20Scutch_Scarlet/Scutch%20Case%20History.pdf https://ecir.groups.io/g/CaseHistory/album?id=78891 |

Hi Stacey,
That exercise and trailering could explain your high ACTH. What did your vet say about it? Did she suggest medication? Next time you have blood drawn, have the vet pull blood before they even look at him, sedate him, exercise him, or anything happens that stresses him out (like separation from his herd/buddy). As for the trailering, that is unfortunate because it's been shown to elevate ACTH to some degree, even in horses that are used to being trailered and don't get stressed. A TRH Stimulation test will not cause laminitis. I know our usual vet was able to source TRH from the US about 3 years ago, so you could ask them to look into it again for your spring appt. But it really should be done on your property. If that's not possible for your current vet, you could ask our new local vet to do a TRH Stimulation in January or later, or come and do another baseline ACTH around Sept 21 next year, on your property. Given his age it's very likely this was a one-off elevation due to all the stresses at the time of the blood draw, but I wouldn't discount it entirely because of his laminitis last winter. -- Kirsten and Shaku (EMS + PPID) and Snickers (EMS) - 2019 Kitimat, BC, Canada ECIR Group Moderator Shaku's Photo Album Snickers' Case History Snickers' Photo Album |
