Blood group and ovarian hyperstimulation syndrome.
2009
Blood group does not constitute a risk factor for the onset of the early form of ovarian hyperstimulation syndrome in women "at risk."
Ovarian Hyperstimulation Syndrome as a Growing Diagnostic Problem in Emergency Department Settings: A Case Report.
2018
Abstract Background Ovarian hyperstimulation syndrome (OHSS) is a common complication of an in-vitro fertilization (IVF) procedure, which is usually clinically insignificant. However, without monitoring, it can progress into a life-threatening condition. With the increasing popularity of IVF technology, patients with OHSS may begin visiting emergency departments (EDs) more frequently. Case Report We report the case of a patient admitted to the ED presenting with severe abdominal pain, cough, and nausea. An ultrasound examination was inconclusive. Computer tomography revealed enlarged ovaries and fluid in the pleural cavities, around the liver and spleen, between the bowel loops, and in the …
Ovarian stimulation for ovulation induction and in vitro fertilization in patients with systemic lupus erythematosus and antiphospholipid syndrome.
2008
Objective To review the current evidence regarding the relationship between systemic lupus erythematosus (SLE) and antiphospholipid syndrome and female infertility, as well as the risks associated with ovarian stimulation for ovulation induction and IVF. To establish, based on this information, guidelines for safe and successful assisted reproductive technology (ART). Design A MEDLINE computer search was performed to identify relevant articles. Result(s) Systemic lupus erythematosus and antiphospholipid syndrome are not related to infertility, except for cases of amenorrhea accompanying severe flares, renal insufficiency-related hypofertility, and ovarian failure secondary to cyclophosphami…
Physiology and Pathology of Ovarian Hyperstimulation Syndrome
2010
Ovarian hyperstimulation syndrome (OHSS) occurs when ovaries primed with follicle-stimulating hormone/leuteinizing hormone (LH) are subsequently exposed to human chorionic gonadotropin (hCG). The ultimate pathophysiological step underlying this clinical picture is increased vascular permeability (VP). With the administration of hCG, the expression vascular endothelial growth factor (VEGF) and VEGF receptor 2 (VEGFR-2) mRNA increases significantly rising to a maximum coinciding with peaked VP. Immunohistochemistry shows the presence of VEGF and VEGFR-2 proteins in the granulosa-lutein and endothelial cells of the entire corpus luteum. These findings suggest that the syndrome can be prevented…
Targeting the vascular endothelial growth factor system to prevent ovarian hyperstimulation syndrome
2008
BACKGROUND: Ovarian hyperstimulation syndrome (OHSS) typically occurs when ovaries are primed with FSH/ LH and subsequently exposed to hCG. The ultimate pathophysiological step underlying this clinical picture is increased vascular permeability (VP). METHODS: A search of the literature was carried out using PubMed and the authors’ files. RESULTS: In rodents and humans, the expression of vascular endothelial growth factor (VEGF) and VEGF receptor 2 (VEGFR-2) mRNA increases during ovarian stimulation. With the administration of hCG, the expression of each rises to a maximum. Expression of VEGF/VEGFR-2 mRNAs correlates with enhanced VP, with both peaking 48 h following an injection of hCG. Imm…
Prevention of OHSS: Current strategies and new insights
2010
Abstract Ovarian hyperstimulation syndrome (OHSS) is an iatrogenic and potentially life threatening condition that affects young healthy patients. Many strategies have been proposed to prevent this syndrome. However, to avoid OHSS without compromising on IVF outcome is still a challenge. The most important action is to identify patients at risk even before ovarian stimulation is initiated and to give them special attention. Coasting is the most popular method to avoid/minimize OHSS. Cycle cancellation, cryopreservation, GnRH antagonists, GnRH agonists, i.v. albumin are other strategies that can provide some kind of benefit but do not completely avoid both early and late forms of OHSS and/or…
