What Is Equine Cushing’s Syndrome
Equine Cushing’s Syndrome (ECS), also known as Pituitary Pars Intermedia Dysfunction (PPID), is an endocrine disorder predominantly affecting older horses. Recognizing the importance of awareness, we at FarmLab Diagnostics aim to guide horse owners through understanding the causes, diagnosis, and management of ECS.
What Causes ECS?
At the core of ECS is a dysfunction in the pituitary gland’s pars intermedia. This dysfunction leads to an overproduction of adrenocorticotropic hormone (ACTH), which in turn causes the adrenal glands to produce excessive cortisol. This hormone imbalance manifests in symptoms such as hirsutism (a long, curly hair coat), increased thirst and urination, laminitis, and muscle wasting.
Diagnosing ECS
The key to diagnosing ECS lies in measuring plasma ACTH levels, which can vary seasonally. Here’s what the process involves:
- Clinical Examination: Vets look for symptoms like unusual hair growth, increased thirst and urination, and signs of laminitis.
- ACTH Measurement: A blood sample is collected to check ACTH levels. Handling and timing are crucial, as samples should be cool and tested considering seasonal ACTH fluctuations.
- Interpreting Results: Results are compared against seasonally adjusted reference ranges to confirm ECS.
Managing ECS
Though ECS is chronic, effective management is possible through:
- Medications: Pergolide mesylate is commonly used to regulate pituitary function.
- Diet: A low sugar and carbohydrate diet helps manage insulin resistance.
- Exercise: Regular activity is encouraged to maintain muscle tone and manage weight.
- Regular Monitoring: Ongoing veterinary check-ups and ACTH tests are essential to adapt the treatment plan as needed.
- Hoof Care: Regular care from a professional farrier helps manage laminitis risks.
With early diagnosis and proactive management, horses with ECS can enjoy a good quality of life. At FarmLab Diagnostics, we are committed to supporting horse owners with accurate diagnostics and practical guidance. For detailed information or to schedule a test, visit our services page.
