Q

Hvilke dyr rammes oftest af pancreatitis og hvordan diagnosticeres det?

A

Hund og kat - sjælden i andre dyr

  • klinisk
  • billeddiagnostik
  • laboratoriske abnormaliteter: stigning i amylase og lipase men begge skal stige meget før det tillægges værdi

Q

Hvornår kigger man på TLI?

A
  • lav sensitivitet ved pancreatitis –> stigning

- falder ved exocrin pancreas insufficiens (EPI)

  • hyperglycæmi
  • dehydrering
  • azotæmi
  • øget ALAT
  • øget BASP (cholestasis)

Q

Angiv halveringstiderne for CK, ASAT og LDH

A
  • CK: kort (normaliseres indenfor 2-3 dage)
  • ASAT: længere halveringstid end CK men stiger langsommere
  • LDH: lav specifitet
