Dear Diane:
I agree strongly with Dr. Karen's request for more information, but I
would like to go a little far on this one. Ferrets rarely if ever
develop Cushing's disease. Cushing's disease is oversecrtetion of
cortisol, a hormone manufactured in the adrenal gland. Less than 25%
of ferrets with adrenal disease secrete elevated levels of cortisol,
and only extremely rarely is it elevated to a point where it might
cause clinical disease. I would have to look long and hard at the
bloodwork and question your vet, because I generally interpret a
discussion on Cushing's disease in ferrets to be a sign of either a
loakc of ferret knowledge, or a significant miscommunication of the
facts. Additionally, traditional bloodwork outside of the Tennessee
adrenal panel is highly NON-predictive of adrenal disease in ferrets.
While long-term prednisolone treatment may mimic true Cushing's
disease (prednisolone is a cortisol analogue), her dosage is not
terribly high, and I think the likelihood of iatrogenic (doctor-
induced) Cushings disease is very low.
But more info on this case would be appreciated.
With kindest regards,
