Luteale Insuffizienz bei der Hündin – Symptome, Diagnose, Folgen und Therapie

Abstract: ZusammenfassungDie unzureichende Synthese von Progesteron (Hypoluteoidismus, luteale Insuffizienz) ist eine Infertilitätsursache bei der Hündin. Ohne Beachtung der dynamischen Veränderungen der Progesteronkonzentration im Reproduktionszyklus kann die Diagnose Schwierigkeiten bereiten. Die Hündin ovuliert bei einer Serumkonzentration von 5–10 ng/ml (15,7–31,4 nmol/l). In den folgenden 3–4 Wochen steigen die Werte bis auf über 25 ng/ml (~78,5 nmol/l) an und fallen nach einer 7- bis 14-tägigen Plateauphase allmäh… Show more

“…When combined with the greater imprecision, using the POC to detect clinical trends can be problematic. When managing high-risk pregnancies, for example, P4 supplementation must be started if the bitch falls below 5 ng/mL prior to day 58 to 60 from ovulation (22)(23)(24). Given the results illustrated in Figure 1, the POC is unlikely to detect this critical threshold and could lead to untreated pre-term labor and abortion.…”

“…In addition to its use for breeding management, serum P4 measurement is a critical tool throughout gestation and around parturition for monitoring high-risk pregnancies and determining the timing of intervention if needed. Hypoluteoidism or luteal insufficiency results in a premature drop in serum P4, leading to embryonic resorption or abortion of fetuses (22)(23)(24). Progesterone supplementation may become necessary to maintain the pregnancy and must be initiated when serum P4 falls below 5 ng/mL prior to day 58-60 from ovulation (22)(23)(24).…”
