Ovarian hyperstimulation syndrome: are preventive measures effective?

چکیده
Infertility treatment has been changed dramatically over the last decades with the introduction of the new assisted reproduction techniques (ART). Ovarian stimulation, either to induce ovulation in the management of anovulatory infertility or for controlled ovarian hyperstimulation in the course of in vitrofertilization, is a main part of the various ART. Nevertheless, ovarian stimulation entails the risk for the development of ovarian hyperstimulation syndrome (OHSS), the commonest complication as such. Hence, it is of great importance not only to know how to effectively induce ovulation but also how to prevent this severe potential risk. Ovarian hyperstimulation syndrome is a wellknown and important complication of ovulatory drugs. Its development has been described following ovulation induction with almost every drug used for ovarian stimulation, either in the management of anovulatory infertility or during controlled ovarian hyperstimulation for in-vitro fertilization, having an incidence of 0,5-2% (1). The employment of gonadotropin releasing hormoneagonists (GnRH-a) seems to be associated with an increased incidence of OHSS (2-4). PATHOPHYSIOLOGY

I-31: Antihistamine & Ovarian Hyperstimulation syndrome
Background: Ovarian hyperstimulation syndrome (OHSS) is a rare iatrogenic complication of ovulation stimulation. The pathogenesis of OHSS is uncertain. The crucial event appears to be an increase in capillary permeability by vasoactive mediators such as cytokine and histamine. The aim of this study is to evaluate the role of loratadine (antihistamine) in preventing ovarian hyperstimulation synd...

Ovarian mutilating surgery is not an option in the management of ovarian hyperstimulation syndrome (OHSS), except in cases with evident tissue necrosis after torsion. When severe OHSS occurs, preservation of fertility must be the target. Therefore, conservative management should be the only feasible approach, as recommended in literature worldwide. Individualization of controlled ovarian hypers...

Type 2 receptors for vascular endothelial growth factor are believed to be involved in the pathophysiology of ovarian hyperstimulation syndrome (OHSS). The objective of this study was to examine the preventive effects of cabergoline on OHSS and its complications. The study is a non randomized clinical trial conducted in 2006-2008 on 75 patients, which were at risk of OHSS and underwent assisted...
متن کاملPrevention and treatment of ovarian hyperstimulation syndrome.
The ovarian hyperstimulation syndrome (OHSS) is a potentially fatal condition with a pathophysiology that is not clearly understood. A shift in fluid from the extravascular space occurs, thought to be induced by cytokines and/or vascular endothelial growth factor. Human chorionic gonadotrophin (hCG), exogenous or endogenous, seems to be the triggering mechanism, resulting in early and late deve...
