          Abstract

          Ovarian hyperstimulation syndrome (OHSS) is a life- threatening complication of controlled ovarian stimulation. One of the main symptoms of OHSS is ascites. Treatment is symptomatic with resolution of the symptoms over days to weeks. We report a case of severe OHSS with persistent ascites 18 months after the diagnosis. Persistent ascites secondary to OHSS was diagnosed and single dose leuprolide acetate depot 11.25 mg was administered. At follow-up, no ascites was observed.

          The use of gonadotropin-releasing hormone (GnRH) agonist to induce oocyte maturation after cotreatment with GnRH antagonist in high-risk patients undergoing in vitro fertilization prevents the risk of ovarian hyperstimulation syndrome: a prospective randomized controlled study.

          To determine whether there are any differences in the incidence of ovarian hyperstimulation syndrome (OHSS) and implantation rates in high-risk patients undergoing IVF using a protocol consisting of GnRH agonist trigger after cotreatment with GnRH antagonist or hCG trigger after dual pituitary suppression protocol. Prospective randomized controlled trial. University-based tertiary fertility center. Sixty-six patients under 40 years of age with polycystic ovarian syndrome, polycystic ovarian morphology, or previous high response undergoing IVF. Patients were randomized to an ovarian stimulation protocol consisting of either GnRH agonist trigger after cotreatment with GnRH antagonist (study group) or hCG trigger after dual pituitary suppression with a GnRH agonist (control group). Both groups received luteal phase and early pregnancy supplementation with IM progesterone (P), and patients in the study group also received E(2) patches and their doses were adjusted according to the serum levels. Incidence of OHSS and implantation rate. None of the patients in the study group developed any form of OHSS compared with 31% (10/32) of the patients in the control group. There were no significant differences in the implantation (22/61 [36.0%] vs. 20/64 [31.0%]), clinical pregnancy (17/30 [56.7%] vs. 15/29 [51.7%]), and ongoing pregnancy rates (16/30 [53.3%] vs. 14/29 [48.3%]) between the study and control groups, respectively. The use of a protocol consisting of GnRH agonist trigger after GnRH antagonist cotreatment combined with adequate luteal phase and early pregnancy E(2) and P supplementation reduces the risk of OHSS in high-risk patients undergoing IVF without affecting implantation rate.

            Ovarian hyperstimulation syndrome

            Ovarian hyperstimulation syndrome (OHSS) is an iatrogenic complication of assisted reproduction technology. The syndrome is characterized by cystic enlargement of the ovaries and a fluid shift from the intravascular to the third space due to increased capillary permeability and ovarian neoangiogenesis. Its occurrence is dependent on the administration of human chorionic gonadotrophin (hCG). β-hCG and its analogs, estrogen, estradiol, prolactin, histamine and prostaglandins have all been implicated in OHSS but now it is increasingly better understood that the vasoactivesubstances such as interleukins, tumor necrosis factor-α, endothelin-1, and vascular endothelial growth factor (VEGF) secreted by the ovaries have been implicated in increasing vascular permeability. Enlargement of the ovaries causes abdominal pain, nausea and vomiting. Leakage of fluid from follicles, increased capillary permeability leading to third spacing (due to the release of vasoactive substances), or frank rupture of follicles can all cause ascites. Due to leakage of fluid through the impaired blood vessels both within and outside the ovary there is massive fluid-shift from the intra-vescular bed to the third compartment results in intravascular hypovolemia with concomitant development of edema, ascites, hydrothorax and/or hydropericardium. Low-dose gonadotrophin protocols have been implemented to reduce the risks of fertility treatment in polycystic ovary syndrome patients. Prophylactic albumin administration may interrupt the development of OHSS by increasing the plasma oncotic pressure and binding mediators of ovarian origin. OHSS is significantly lower in an antagonist protocol than in an agonist protocol. Cabergoline inhibits partially the VEGF receptor 2 phosphorylation levels and associated vascular permeability without affecting luteal angiogenesis reduces the ‘early’ (within the first 9 days after hCG) onset of OHSS. To prevent thrombosis, subcutaneous heparin 5000-7500 U/d is begun on the first day of admission. These patients need a hospital ward where the clinical picture is well understood and the personnel have expertise in its treatment and follow-up. Admission to an intensive care unit is necessary when critical OHSS develops.

              Induction of preovulatory luteinizing hormone surge and prevention of ovarian hyperstimulation syndrome by gonadotropin-releasing hormone agonist.

              To use gonadotropin-releasing hormone agonist (GnRH-a) instead of human chorionic gonadotropin (hCG) to induce oocyte maturation for in vitro fertilization (IVF). Pituitary and ovarian responses to GnRH-a and the outcome of IVF were studied prospectively. Data from patients injected with hCG were analyzed retrospectively. Program of IVF at the Rambam (Governmental) Hospital, Haifa, Israel. One or two doses of buserelin acetate 250 to 500 micrograms were administered to six patients with moderate response (Estradiol [E2], 1,494 +/- 422 [+/- SD] pg/mL) and 8 patients with exaggerated response (E2, 7,673 +/- 3,028 pg/mL) to gonadotropin stimulation. Progesterone (P) and E2 were administered for luteal support. Gonadotropin-releasing hormone agonist effectively triggered luteinizing hormone (LH)/follicle-stimulating hormone (FSH) surge. Mature oocytes were recovered in all patients. Luteal E2 and P were lower than in patients injected with hCG. No signs of ovarian hyperstimulation syndrome were observed. Serum LH and FSH rose over 4 and 12 hours, respectively, and were significantly (P less than 0.05) elevated for 24 hours. Of all mature oocytes, 67% fertilized and 82% cleaved. Four pregnancies were obtained. A bolus of GnRH-a is able to trigger an adequate midcycle LH/FSH surge, resulting in oocyte maturation and pregnancy. Our preliminary results also suggest that it allows a more accurate control of ovarian steroid levels during the luteal phase and may prevent the clinical manifestation of ovarian hyperstimulation syndrome.
