Seasonal influence on the pituitary gland - what it means for your PPID cases

July 31, 2018

For years, vets and researchers have recognised a seasonal influence on the pituitary gland in equine Cushing’s disease cases and normal horses.  This seasonal influence is the reason why we have seasonal (or in Liphook’s case, weekly) adjusted reference intervals for basal ACTH testing.  The seasonal influence on the pituitary gland also impacts on our interpretation of follow-up tests when starting or monitoring a horse on pergolide therapy.  Check out this latest podcast where Victoria South and Andy Durham discuss a variety of PPID scenarios that many of us are facing at this time of year.
