Abstract: | Vascular endothelial growth factor (VEGF) is the most important angiogenic mediator in ovarian hyperstimulation syndrome OHSS. Studies proved that cabergoline administration blocks the increase in vascular permeability via dephosphorylation of VEGF receptors and hence can be used as prophylactic agent against OHSS. This study aimed at evaluating the effectiveness of early administration of cabergoline in the prevention of OHSS in high risk cases prepared for ICSI. This case series study was conducted on 126 high risk patients prepared for ICSI using the fixed antagonist protocol. High risk patients were defined as having more than 20 follicles >12 mm in diameter, and/or E2 more than 3000 pg/ml when the size of the leading follicle is more than 15 mm. When the size of the leading follicle reached 15 mm, cabergoline was administered (0.5 mg/day) for 8 days. Patients were followed up clinically, ultrasonographically and hematologically. The final E2 was 6099.5 ± 2730 and the mean number of retrieved oocytes was 19.7 ± 7.8. The clinical pregnancy rate was 62/126 (49.2%). There were no significant changes (p > 0.05) comparing hematological parameters, renal function tests and liver function tests between the day of HCG and the day of blastocyst transfer. The incidence of severe OHSS in this group was 1/126 (0.9%), while moderate OHSS was 12 (9.5%) and there were no cases of critical OHSS. We concluded that early administration of cabergoline is a safe and potentially more effective approach for prophylaxis against OHSS in high risk cases. |
