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