Zusammenfassung
Fragestellung
Follitropin alfa (Gonal-F®) rekombinantes follikelstimulierendes Hormon (r-hFSH) entspricht
dem endogenen humanem FSH. Seine Vorteile im Vergleich zu urinärem FSH liegen in der
Chargenkonformität und seiner hohen Reinheit. Follitropin alfa kann von der Patientin
selbst subkutan appliziert werden. Studien konnten eine höhere Effizienz von Follitropin
alfa im Vergleich zu urinärem FSH zeigen. In einer Beobachtungsstudie mit hoher Patientenzahl
sollte die Wirksamkeit von Follitropin alfa bei Patientinnen im Rahmen der Ovulationsinduktion
in der alltäglichen Praxisroutine dokumentiert werden.
Patientinnen und Methodik
Bei 728 Patientinnen wurden 1371 Ovulationszyklen dokumentiert. Bei 204 Patientinnen
(378 Zyklen) folgte nach der ovariellen Stimulation der Geschlechtsverkehr (GV) zum
zeitlichen Optimum, bei 524 Patientinnen (993 Zyklen) die intrauterine Insemination
(IUI).
Ergebnisse
Die Stimulation dauerte durchschnittlich 10 Tage bei einer kumulativen Gesamtdosis
von 1050 IE, entsprechend 14 Ampullen je 75 IE Follitropin alfa. In 32,5 % der Zyklen
führte die Stimulation zur Entwicklung eines Follikels ≥ 15 mm, in 25,8 % zu zwei
und in 13,3 % zu drei Follikeln. In nur insgesamt 15 Zyklen wurde auf die Ovulationsauslösung
verzichtet, in 94 Zyklen wurde für die Ovulationsauslösung eine Alternative zu hCG
gewählt bzw. die Spontanovulation genutzt. Der Östradiolwert am Tag der hCG-Gabe betrug
durchschnittlich 473 pg/ml (1736 pmol/l). Die klinische Schwangerschaftsrate pro Zyklus
lag bei 18,6 %, die Abortrate bei 14,5 %. Zu einem Überstimulationssyndrom kam es
in 14 Zyklen (1,0 %).
Schlussfolgerungen
Follitropin alfa führt in Ovulationsinduktionszyklen mit GV oder IUI zu guten Schwangerschaftsraten.
Eine niedrig dosierte Therapie könnte helfen, das Risiko für Mehrlingsschwangerschaften
zu reduzieren.
Summary
Objective
Objective
Follitropin alpha recombinant follicle stimulating hormone (r-hFSH) is identical to
endogenous FSH. Compared with urinary FSH, the recombinant form has high batch-to-batch
consistency and purity and is more effective. r-hFSH can be self-administered. We
conducted a post-surveillance study on the efficacy of r-hFSH for ovulation induction
cycles.
Methods
We documented 1371 ovulation-induction cycles in 728 patients (328 cycles in 204 women
with timed intercourse and 993 cycles in 524 patients with intrauterine insemination).
Results
The average duration of stimulation was 10 days with an average cumulative r-hFSH
dose of 1050 IU (14 ampoules of 75 IU). 32.5 % of the cycles achieved one, 26 % two,
and 13 % three follicles ≥ 15 mm. Only 15 cycles were cancelled because of risk for
ovarian hyperstimulation. In 94 cycles ovulation was triggered with an alternative
to hCG or was spontaneous. The mean estradiol level on the day of hCG administration
was 473 pg/mL (1736 pmol/L). The clinical pregnancy rate was 19 % with an abortion
rate of 14.5 %. Severe ovarian hyperstimulation developed in 14 cycles (1.0 %).
Conclusion
r-hFSH for induction of ovulation and with subsequent timed intercourse or intrauterine
insemination results in good pregnancy rates. Low-dose protocols might reduce the
rate of multiple pregnancies.
