Clinical Trial Summary

This a prospective randomized double blind study involving patients at high risk of OHSS development with peak serum E2 levels < 4,000 pg/ml comparing the ongoing pregnancy rates in patients who receive adjuvant hCG 1,000 IU at the time of GnRH agonist trigger or adjuvant hCG 1,500 IU 35 hours after GnRH agonist trigger.


Description:

Ovarian hyperstimulation syndrome (OHSS) is an iatrogenic complication of controlled ovarian hyperstimulation which may result in significant morbidity and rarely mortality as well as significant financial and psychological distress. GnRH agonist trigger has been shown to be effective in OHSS prevention. However, the adoption of its use has not been widely accepted in view of concerns regarding potential impairment of implantation.

Intensive luteal phase supplementation with estrogen (E2) and progesterone (P) is important due to the strong evidence of abnormal luteal phase serum E2 and P profiles. However, it has been shown that optimal conception rates is not achieved for high risk patients with peak serum E2 < 4,000 pg/ml despite aggressive steroidal supplementation. It has been proposed that the use of adjuvant low dose hCG at the time of GnRH agonist trigger or 35 hours later will rescue some of the corpora lutea and help improve corpora lutea function and improve pregnancy rates.

The study will evaluate patients at high risk of OHSS development with peak serum E2 < 4,000 pg/mL to determine whether timing of low dose hCG administration affects ongoing pregnancy rates or risk of OHSS. Markers of corpus luteum function such as serum 17 hydroxy-progesterone and prorenin during the luteal phase and early pregnancy will help elucidate further the effect of adjuvant low dose hCG with GnRH agonist trigger on corpus luteum function.

Outcome

Type Measure Description Time frame Safety issue
Other Markers of Corpus Luteum Function A subset of patients (20 patients in each group) will have serum frozen for subsequent analysis of 17 hydroxy progesterone and prorenin. Within 60 days after trigger of oocyte maturation
Other Proportion of Patients With Abdominal Distension Patients will complete a questionnaire to determine if there is a difference in the effect of the intervention on the quality of life (abdominal distension) of the patients from the day of trigger of oocyte maturation until menses or positive pregnancy test. Within 2 weeks after trigger of oocyte maturation
Primary Ongoing Pregnancy Positive serum pregnancy test and ultrasound evidence of fetal pole and fetal heart rate . Through time of study completion, on average 1-2years
Secondary Ovarian Hyperstimulation Syndrome Evaluation of symptoms and signs of OHSS at 9 days after trigger of oocyte maturation. Patients who also present with symptoms of OHSS wil also be evaluated for OHSS within 4 weeks after oocyte maturation. Within 4 weeks of oocyte retrieval
