THE ROLE OF HIGH FOLLICULAR LEVELS OF ANGIOTENSIN II AND VASCULAR ENDOTHELIAL GROWTH FACTOR IN ANTICIPATING THE DEVELOPMENT OF SEVERE OVARIAN HYPERSTIMULATION SYNDROME IN PATIENTS WITH PROPHYLACTIC CABERGOLINE THERAPY UNDERGOING AN IN VITRO FERTILIZATION PROCEDURE

Abstract

Severe Ovarian Hyperstimulation Syndrome (OHSS) forms with very aggressive clinical evolution are still common, despite prophylactic measures. Besides the Vascular Endothelial Growth Factor (VEGF), there are other angiogenic factors, like Renin-Angiotensin-Aldosterone System (RAS), that might be associated with this disorder. Our study aims to evaluate the role of VEGF and Angiotensin II (ANG II) in the development of early severe OHSS, in high risk patients under prophylactic Cabergoline therapy. We recruited 192 patients undergoing in vitro fertilization (IVF) procedures with high risk for OHSS development. Out of these, 106 patients with OHSS were enrolled in the study, of which 28 subjects had a severe form of disease (group I), and 78 patients had a mild/moderate form (group II). We collected blood and follicular fluid from our study participants and determined serum and follicular VEGF and ANG II levels using Enzyme-Linked Immunosorbent Assay (ELISA) technique. Follicular VEGF, ANG II, and serum VEGF levels were significantly higher in group I versus group II. Serum VEGF titers were 645.97 versus 548.62 (p = 0.0008), follicular VEGF titers were 2919.52 versus 1093.68 (p < 0.0001), and follicular ANG II levels were 281.64 ...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
