Equine metabolic syndrome (EMS), pituitary pars intermedia dysfunction (PPID), medication induced hypothyroxinemia (e.g. Certain breeds or individual horses are predisposed and often referred to It often affects “thrifty” equids such as ponies, donkeys, Arabians, and mustangs. ELISA tests can also be used to measure a horse’s hormone levels, such as insulin or adrenocorticotropic hormone (ACTH), to look for metabolic diseases. Abnormally high insulin is a key feature of Equine Metabolic Syndrome (EMS) and is responsible for the high laminitis risk, but there has been considerable uncertainty regarding the best way to test for abnormal insulin and how results are interpreted for diagnosis. Pituitary Pars Intermedia Dysfunction (PPID) — Equine Cushing's Disease. Insulin results are most reliable if the horse has not eaten any concentrate (grain or sweet feed) for at least 4 hours before drawing blood. Insulin is one of the most variable of lab tests. Equine metabolic syndrome can be diagnosed by the history, detection of obesity or regional adiposity, and test results consistent with IR. Insulin in the Equine. PPID/Cushing's Disease is a disorder of the pituitary gland and results in hormonal disturbances. Affected horses commonly show increased regional fat deposition and a reduced ability to lose weight. Equine Metabolic Syndrome (EMS) is characterized by three main features: obesity or regional adiposity (accumulation of fat in certain areas, particularly the neck), insulin resistance (IR) a “pre-diabetic” like state, and laminitis in horses and ponies. It is measured in suspected cases of equine metabolic syndrome and sometimes in cases of equine Cushing’s disease. these questions, your horse might be suffering from equine metabolic syndrome (EMS). Horses should be screened for IR by collecting a blood sample and submitting plasma for … In combination with clinical signs and results of other tests results could signify the following; Muscle injury . Extensive tissue damage (especially muscle). Horses with EMS are at a … The pituitary gland secretes high levels of the hormone ACTH (adrenocorticotrophic hormone), which stimulates the production of cortisol, a stress hormone. Diagnosing Equine Metabolic Syndrome January 21, 2010 December 13, 2017 By Kentucky Equine Research Staff. It has some similarities with Cushing’s Disease, most notably in … Equine pituitary pars intermedia dysfunction is another endocrine disease, previously known as Cushing’s disease. Testing insulin levels forms part of the diagnosis of Equine Metabolic Syndrome (EMS), and gives information about insulin dysregulation and laminitis risk. Equine Metabolic Syndrome (EMS) is a wide-spread issue in the horse population. “Leptin [a hormone produced by fat cells] is another thing the lab can look for. Normal T3 and T4 essentially rules out thyroid disease in horses. ... Metabolic acidosis. phenylbutazone, corticosteroids, possibly sulfa drugs), and euthyroid What is equine metabolic syndrome? ... these tests are complicated and not commonly performed, even in hospital settings. Some are offering this as an insulin resistance panel when checking for equine metabolic syndrome,” True says. The disease also raises insulin levels, which can make equine metabolic syndrome worse. Equine Thyroid Panel (T3, T4) Primary hypothyroidism is considered rare in horses. … Acute renal failure . But, says equine researcher Ray J. Equine Metabolic Syndrome. Equine Metabolic Syndrome (EMS), previously known as Peripheral Cushing’s Disease, is a hormonal disorder of horses, and more commonly ponies that has been identified in the recent past. If you answered ‘yes’ to any or all of. EMS likely begins with a genetic pre-disposition. “PPID is seen in middle-aged horses as well as the aged horse,” says Dr. Nicholas Frank. Screening Tests. Takeaways Equine metabolic syndrome (EMS) is a disorder associated with an inability to regulate blood insulin levels (insulin dysregulation). Acute renal failure . There are currently no perfect tests for diagnosing EMS or insulin dysregulation. All horses suspected of having PPID should also have insulin tested to assess their laminitis risk.
