[Diagnose/Therapie] Mysteriöse Krankheit, mehrere Pferde tot...

lundi 6 octobre 2014

Hallo,



wir leben auf einer kleinen Insel im Mittelmeer.

Das Pony meiner Freundin starb letzte Woche an, was zuerst aussah wie eine Kolik, sich dann aber entwickelte wie eine Nervenkrankheit.



Anscheinend sind inzwischen bereits mehrere Pferde auf der Insel daran gestorben, alle in den letzten Wochen.

ABER nicht im gleichen Stal sondern über die Insel verteilt.

Verlauf ist immer gleich, wenn auch normalerweise langsamer verlaufend.



Irgendeine Idee/Erfahrung?

Leider spricht keinerlei Behandlung an, gestern wieder ein Pferd betroffen, gleicher Ort anderer Stall.



Hier einmal ein genauer Krankheitsverlauf.

Wenn ihr eine Übersetzung möchtet, schreibe ich die später gerne:



Skye was a 16-year old Shetland mare. She spent her day in the paddock as usual on Friday (26/09/14) where she seemed fine. I led her in at around 6.30pm, groomed her then took her inside her stable for feeding. Very unusually, she refused her feed and lay down. This alarmed me as she was a pony with an appetite, and it was unusual to find her resting at this hour. I also realised she did not urinate, which is usually the first thing she would do on entering her stall. I suspected colic so I immediately began to walk her while I called my my vet. She was however passing gas. My vet confirmed she had a slight fever in conjunction with her colic, which is what she was treated for at that point. I noticed slight trembling of her stifles, which was assumed to be due to pain or possibly fatigue. By around 1.30 am, her fever reduced and we gave her some time to 'heal'.

The next morning (27/09/14) at around 7am, she still seemed uncomfortable so again I began to walk her until my vet arrived to re-monitor her. There was some faeces in her stall which was expected due to the parafin oil previously given through a tube, but no sign of urine overnight and this concerned me. I began to walk her again for a few minutes at around 11am and noticed slight dragging of the toes of her hind quarters. By the time my vet arrived, she was already much weaker. Her fever was borderline, but we had to support her from her tail as he examined her taking a few steps outside her stall. On crossing her legs in a sensitivity assessment (placing one hind hoof over the other) there was no automatic or reflexive re-positioning. I realised he was looking for clinical signs of a neurological disorder (ie clapping hands/flicking fingers within her vision), which she responded to. We immediately took blood samples for testing, which was difficult being a Saturday evening as our facilities are extremely limited. Until then we began palliative care, giving IV anti-inflammatory drugs/antibiotics/'something for the nerves' (vet did not specify) and also a drip (she had an appetite but would not drink any water). I found somebody to do me a 'favour' by testing it when the labs were closed, but this was a small animal clinic so some results were missing and therefore inconclusive. We did however rule out infection as her WBC appeared to be in range. My little girl began deteriorating by the hour. She would attempt to walk around her stall, pivoting from behind. She was still able lift her tail to pass gas. Then she got to the point where her hind legs would not move with her, and we would have to arrange them for her to prevent falling over. They appeared very stiff, which made it difficult for me to bend them and place them in a way that was most 'comfortable' (for lack of a better word). Eventually, we literally had to support her from the back and sides in order to maintain her balance. This was around 8pm of the same day, so it all happened within a time frame of literally hours. Skye was exhausted but seemingly afraid to lie down, until she gave way and fell over to her side. She panicked but I lay on the floor and held her head in attempt to calm her down, hoping that she would trust me enough to remain resting for at least a short while. She did. Once her breathing patterns regularised and her broken sweat was reduced, she struggled to get up. She did so using her front legs and we helped her up from behind, once again supporting her. Granted we were a total of 5 persons, but this was only possible because she was relatively small in size. The colic was surely an issue that redeveloped, considering she had still not urinated or self-excreted in over 24 hours. My Skye lay on the floor, given up.

By around 2am (28/09/14), the paresis developed to almost complete paralysis. She became dehydrated and jaundice was emerging. She was not responding to pin pricks in her hind lower legs. On leaving her alone for visual assessment, Skye engaged in 'dog-sitting' in attempt to stand up. This was in vain so she called out for help. There was nothing more to do for her medically, so my pony was put to sleep.

My research led me to EPM and EHV-1 with Cauda Equina syndrome relations, however this is based merely on the symptoms. I also looked at Wobbler syndrome, but it seemed less likely. Looking back (around a week or two prior to the Skye's death), I did suspect moderately unusual gait. Her hind legs looked very slightly spread when walking, almost in the same way stifle-locking presents. She was prone to this so I began creating forward movement in brief exercises as one might do in a case of UFP. She also appeared to be somewhat pigeon-toed when leading (she did not have heavy work), so I intended to have her hooves clipped and filed in order to rule out superficial causes of tenderness. This made me wonder whether a slow onset with such fast progression would make sense if these were really 'early signs'. It could indeed be an over-analysis and completely unrelated, but my thoughts were there. My angel is gone but whether this is viral or genetic or idiopathic, and if it is in fact related to the increasing cases on the island, all information is useful.
