Laminitis, an extremely painful disease of the equine foot, is most commonly caused by elevated insulin
concentrations in blood (hyperinsulinemia). Therefore, strategies to reduce hyperinsulinemia in horses are warranted.
Studies in obese children with insulin dysregulation and hyperinsulinemia have identified elevated levels of the
hormone glucagon in blood. To identify novel treatment strategies for preventing laminitis we compared insulin
dysregulation in the horse with that observed in humans. We found that horses with insulin dysregulation also had an
excessive glucagon secretion during an oral sugar test in a small pilot study.
If the results of the pilot study hold true also for a larger population of horses, this would be a breakthrough in the
understanding of the pathophysiology of insulin dysregulation in the horse. This opens up for medical treatment of
these horses since there are treatment strategies for an abnormal glucagon response in humans with -cell
dysregulation.
Fång, en smärtsam sjukdom som drabbas hästens hov, orsakas i de flesta fall av förhöjda koncentrationer av insulin i
blodet (hyperinsulinemi). På grund av detta samband finns det ett stort behov av att finna metoder, som minskar
graden av hyperinsulinemi hos häst.Studier utförda på överviktiga barn med störd insulinmetabolism och hyperinsulinemi har funnit förhöjda nivåer av hormonet glukagon i blodet. I likhet med dessa resultat har vår forskargrupp i en mindre pilotstudie visat att hästar med hyperinsulinemi också hade en ökad frisättning av glukagon under ett oralt glukostoleranstest.
Om vi studerar detta samband i en större hästpopulation och då påvisar samma resultat som i pilotstudien, skulle det
innebära ett stor genombrott i förståelsen om hur hyperinsulinemi uppstår hos häst. Det skulle innebära att nya
behandlingsmetoder mot hyperinsulinemi hos häst blir tillgängliga, då det redan finns behandlingsstrategier med
läkemedel vid störd glukagonmetabolism hos människa.

A few years ago, media reported on a 7 year-old girl who was killed during a riding lesson. The accident evokes questions about children, horses and safety. Children are small and horses big, and the horse is a herd and prey animal whose behaviour is partly controlled by instincts. Today, many …
