  • Recommendations for the Diagnosis and Treatment of Equine Metabolic Syndrome (EMS)
    Recommendations for the Diagnosis and Treatment of Equine Metabolic Syndrome (EMS) 2016 GROUP GROUP Recommendations for the Diagnosis and Treatment of Equine Metabolic Syndrome (EMS) June 2016 Prepared by the EMS Working Group Nicholas Frank (Group Coordinator; Tufts University), Simon Bailey (University of Melbourne), Andy Durham (Liphook Equine Hospital), Janice Kritchevsky (Purdue University), Nicola Menzies-Gow (Royal Veterinary College), and Lisa Tadros (Michigan State University) Introduction Equine metabolic syndrome (EMS), which is characterized by insulin dysregulation, abnormal adipose distribution, and a high risk for laminitis, results from an interaction between genetics and environment. The risk of laminitis in the individual animal therefore depends on the relative weighting of genetic and environmental influences. We can identify high-genetic risk animals that develop EMS with only mild environmental influences, and early detection is essential in these animals. Other horses have a lower genetic influence, but can develop EMS through exposure to improper environments (diets that provide more calories than an animal requires and are high in non-structural carbohydrates). It might therefore be assumed that any horse can develop EMS if pushed far enough in the wrong direction by improper management and exposure to environmental factors. Epigenetic influences on gene expression might also further the development of EMS. The Equine Endocrinology Group (EEG) is composed of experts in the field of equine endocrinology who provide advice in the form of written guidelines to help veterinary practitioners diagnose and manage equine endocrine disorders. Guidelines are updated every two years or when new information becomes available, and can be found on the EEG web site: http://sites.tufts.edu/equineendogroup.

(Seshu) Ganjam, BVSc, MA (hc), PhD , Nat T. Messer IV, DVM KEYWORDS Endocrinopathic laminitis Insulin resistance Equine metabolic syndrome Obesity Although much has been written about laminitis in the context of its association with inflammatory processes, such as dietary carbohydrate overload and endotoxemia,1–5 recognition is growing that most cases of laminitis examined by veterinarians in private practice are those associated with pasture grazing, obesity, and insulin resistance (IR).6,7 The term endocrinopathic laminitis has been adopted to classify the instances of laminitis in which the origin seems to be more strongly associated with an under- lying endocrinopathy, such as either IR or the influence of corticosteroids.8–11 Results of a recent study suggest that obesity and IR represent the most common metabolic and endocrinopathic predispositions for laminitis in horses.6,12 IR also plays an impor- tant role in the pathogenesis of laminitis that develops when some horses or ponies are allowed to graze pastures at certain times of the year (pasture-associated laminitis [PAL]).12–15 Moreover, IR is provoked by and contributes to pathophysiologic processes associated with endotoxemia and systemic inflammation under the more classic circumstances associated with risk for acute laminitis, such as grain overload, retention of fetal membranes, and gastroenteritis.16,17 However,

  • Are Drugs Effective Treatment for Horses with Acute Laminitis?
    IN-DEPTH: LAMINITIS FOR THE PRACTITIONER Are Drugs Effective Treatment for Horses With Acute Laminitis? William Moyer, DVM; John Schumacher, DVM; Jim Schumacher, DVM, MRCVS; and G. Kent Carter, DVM Currently, the only therapy for horses with acute laminitis for which there is consensus among practitioners is aggressive treatment for the disease process that has initiated laminitis. Although other treatments may have merit and seem logical based on studies of the pathogenesis of laminitis, the efficacy of these treatments has not been proven. Some of the confusion regarding treatment of horses for laminitis is the result of differing theories regarding the pathogenesis of laminitis and failure of clinicians to distinguish between recommendations made for treatment during the devel- opmental (prodromal) stages (i.e., before signs of foot pain are observed) and recommendations for treatment during the acute phase (i.e., when signs of foot pain are apparent). Controlled studies have not shown the efficacy of any drug for treating horses in the acute phase of laminitis.

    J Vet Intern Med 2013;27:1528–1534 Clinical and Clinicopathological Factors Associated with Survival in 44 Horses with Equine Neorickettsiosis (Potomac Horse Fever) F.R. Bertin, A. Reising, N.M. Slovis, P.D. Constable, and S.D. Taylor Background: The epidemiology of equine neorickettsiosis (EN) has been extensively studied but limited clinical and clinicopathological data are available concerning naturally infected horses. Hypothesis: Factors predictive of survival will be identified in horses diagnosed with EN. Animals: Convenience sample of 44 horses with EN admitted to 2 referral institutions. Methods: A retrospective study was performed. A diagnosis of EN was based on the presence of positive blood or fecal PCR. Results: The most common clinical signs included diarrhea (66%), fever (50%), anorexia (45%), depression (39%), colic (39%), and lameness (18%). The median duration of hospitalization was 6 days and 73% of horses survived to dis- charge. Laminitis was present in 36% of horses, 88% of which were affected in all 4 feet. Serum creatinine and urea nitro- gen concentrations, as well as RBC count, blood hemoglobin concentration, hematocrit, band neutrophils, serum AST activity, serum CK activity, and anion gap, were significantly (P < .05) higher in nonsurvivors. Serum chloride and sodium, concentrations as well as duration of hospitalization were significantly lower in nonsurvivors. The results of for- ward stepwise logistic regression indicated that blood hemoglobin concentration on admission and antimicrobial treatment with oxytetracycline were independent factors associated with survival. Conclusions and Clinical Importance: Severity of colitis as reflected by electrolyte loss, hemoconcentration, and prerenal azotemia were predictors of survival in horses diagnosed with EN.

The aetiology of laminitis has been widely studied, but still not completely understood. There is some evidence that pasture associated laminitis is one of the most common forms of laminitis , and this is most likely associated with underlying endocrine dysfunction i.e. insulin resistance. However, what the prevalence of insulin resistance in horses presented with laminitis is, that is currently unknown and it has not been studied previously. Endocrinopathic laminitis is a term including laminitis developing subsequently to Equine Cushing’s Disease, equine metabolic syndrome and iatrogenic corticosteroid-induced laminitis. The term equine metabolic syndrome includes a history of laminitis, insulin resistance and a characteristic phenotype of a cresty neck, bulging supraorbital fat and increased fat deposits. Horses suffering from laminitis and insulin resistance seem to have a slow recovery process, but recovery is more likely if insulin sensitivity is improved. Increased exercise, maintaining optimal body condition, avoidance of high-glycaemic meals and molasses should be incorporated in the treatment of laminitis. Horses with insulin resistance have a higher risk of developing laminitis and to find and treat horses with insulin resistance would be a means of preventing laminitis.

  • Equine Insulin Resistance and the Role the Farrier Plays with This Disease
    Equine Insulin Resistance And the Role the Farrier Plays with this Disease The most common cause of Laminitis today is via the disease Equine Insulin Resistance. Horses of any age can be effected by it. Older horses (>15 years old may have this problem and Equine Cushings disease together. Equine Insulin Resistance (EIR) leads to a pathological elevation of blood Insulin leading directly to Laminitis. Studies just a few years ago in Australia documented that a bolus of Insulin given IV caused Laminitis in all four feet within twenty-four hours. Signs of EIR: 1. Overweight, Fat pads on butt/shoulders 2. Easy keeper – little food but large 3. Laminitis on grass, now on dirt lot while others outside 4. Sore feet after routine trims from talented farrier 5. Stretched white line – high Insulin stretches laminae so bonds are not strong 6. Chronic white line disease 7. Laminitis – acute and chronic 8. High blood Insulin 9. Sore on hard ground or frozen ground 10. On Pergolide but still founders What causes Insulin to be so high to create Laminitis? Due to several possible triggers, there has been interference with Insulin’s normal action. Insulin has several roles, with carbohydrate (sugar) transport to cells being its main job – sugar absorbed from the meal enters the blood stream, signaling the Pancreas to send out Insulin to escort nutrients to cells. Once at the cell, a lock and key system is in place, with Insulin the key opening the lock to allow glucose sugar inside. When the lock and key setup is interfered with, the Pancreas sees that glucose is still in the bloodstream, so it pours more and more Insulin out into the bloodstream to force glucose in – basically more keys put into play.
