Cholicalciferol (vitamín D3) je účinnou látkou mnohých druhov jedov na potkany. Vysoká dávka cholikalciferolu spôsobí destabilizáciu vápnika v tele, čo povedie k stavu hyperkalcémie a nakoniec k vápenateniu tkanív a orgánov tela. Zvýšená hladina vápnika v krvi spôsobí vážne poškodenie obličiek.

Kone občas prídu do styku s krmivom pre koňa, ktoré bolo kontaminované cholikalciferolom, napríklad keď bol jed odložený v skladovacích priestoroch a v dôsledku toho došlo k neúmyselnej otrave. K tomu často dochádza bez vedomia správcu. Požitie tejto zlúčeniny môže nastať aj pri nesprávnom zmiešaní alebo zložení krmiva alebo pri nadmernom horlivom podávaní doplnku vitamínu D3.

Príznaky

  • Strata chuti do jedla (anorexia)
  • Chudnutie
  • Depresia
  • Ťažkosti s dýchaním (dýchavičnosť)
  • Nadmerný smäd (polydipsia) so zvýšenou spotrebou vody
  • Zvýšená tvorba moču (polyúria)
  • Slabosť
  • Zvýšená srdcová frekvencia
  • Tuhosť končatín
  • Ležiaci
  • Smrť

Príčiny

  • Požitie cholikalciferolu, zvyčajne neúmyselne
  • Spravidla zahŕňa kontamináciu potravy jedom na potkany

Diagnóza

Váš veterinárny lekár môže diagnostikovať toxicitu cholikalciferolu predložením vzorky krvi do laboratória, ktoré bude merať sérové hladiny zlúčeniny. Pri rutinnejšej práci s krvou sa ukážu zvýšené hladiny fosforu a vápnika, ako aj príznaky poškodenia obličiek.

Liečba

Liečba otravy cholialciferolom sa bude líšiť od prípadu k prípadu, v závislosti od množstva požitého jedu a závažnosti príznakov.

Najbežnejší prístup k liečbe zvyčajne súvisí s obmedzením množstva vitamínu D prijímaného jedlom a doplnkami. Môže sa podať chelátor vápnika, pretože to zníži intestinálnu absorpciu vápnika. Liečba by sa mala začať aj pri zlyhaní obličiek. Toto je zvyčajne podporná starostlivosť a vyžaduje si podanie veľkého množstva IV tekutín.

Život a správa

Zotavenie z tejto toxikózy môže byť zdĺhavé a často nevhodné, pretože nie je možné zvrátiť kalcifikáciu tkanív a zlyhanie obličiek. Prognóza je strážená a často sa volí eutanázia.

Prevencia

Aj keď sa nedá zabrániť náhodnému požitiu, občas sa tento typ toxikózy vyskytne v dôsledku nesprávneho zaobchádzania s vitamínovými doplnkami. Predtým, ako začnete s akýmkoľvek doplnkom, prekonzultujte to so svojím veterinárom.
