Wirkung des isopropanolischen Cimicifuga-racemosa-­Extrakts iCR auf Uterusmyome bei Frauen mit ­klimakterischen Beschwerden

Zusammenfassung

Der Einfluss des isopropanolischen Cimici­fuga-racemosa-Extrakts iCR auf Uterusmyome wurde an menopausalen Frauen mit klimakterischen Beschwerden untersucht. Die Studienpopulation entstammte einer randomisierten, kontrollierten (vs. Tibolon) Doppelblindstudie. Mit transvaginalen ­Ultraschallmessungen wurden die Tumordurchmesser (dreidimensional) gemessen und die Volumenänderungen im Vorher-­Nachher-Vergleich bestimmt. Nach 12-wöchiger Therapie mit iCR (n=34) war das ­Volumen der Myome deutlich reduziert (-30,3 %) und signifikant unterschiedlich (p=0,016) zu der Zunahme von 4,7 % unter Tibolon (n=28). Die Responderrate (Volumenabnahme) lag für iCR bei 70 % (Tibolon: 36 %). Die Confounder-adjustierte logistische Regression ergab eine 4,7-fach höhere Wahrscheinlichkeit, dass Myome unter iCR kleiner werden als unter Tibolon (p=0,008). Die Ergebnisse dieser Untersuchung weisen auf einen zusätzlichen Nutzen von iCR bei der Therapie klimakterischer Beschwerden von Patientinnen mit Myomen hin.

Summary

Effect of the isopropanolic Cimicifuga racemosa extract iCR on uterus myoma in women with climacteric complaints

The effect of the isopropanolic Cimicifuga racemosa extract iCR on uterus myoma has been studied in menopausal women with climacteric symptoms. The study population derived from a recent randomized, controlled (vs. tibolone) double-blind study. Transvaginal ultrasound was performed for measuring the (three-dimensional) diameters of the myoma, determining changes in volume for the pre-post comparison. After 12 weeks treatment with iCR (n=34), myoma volume was reduced by 30.3%, significantly different to the increase by 4.7% under tibolone (p=0.016). The responder rate (reduction in volume) for iCR was 70% (tibolone: 36%). The confounder-adjusted logistic regression revealed a 4.7 times higher probability of myoma reduction under iCR compared to tibolone (p=0.008). The results demonstrate an additional benefit for iCR during treatment of climacteric symptoms in women with myoma.
