Hypothyreose für den Hund, Hyperthyreose für die Katze. Ja, meistens. Doch manchmal sollte man auch bei Stubentigern mit unklarer Symptomatik an eine Hypothyreose denken.
-
Eine iatrogene Hypothyreose kann bei Thyreostatikagabe, nach Thyreoidektomie oder nach einer Radiojodtherapie auftreten.
-
Mögliche klinische Symptome: Lethargie, ↑Gewicht trotz ↓Appetit, stumpfes Fell
-
Zwei Drittel der betroffenen Katzen zeigen keine klinischen Symptome.
-
Diagnostik:
-
Gesamt-T4 als alleiniger Parameter hat keine Aussagekraft, Interpretation muss immer im (klinischen) Kontext erfolgen.
-
Freies T4 sollte nicht als alleiniger Parameter genutzt werden.
-
Die Messung von Gesamt-T4 + fT4 besitzt die höchste Aussagekraft.
-
TSH kann als ergänzender Parameter (über das canine Assay) die diagnostische Sicherheit erhöhen.
