Angiogenic cytokine and interleukin 8 levels in early luteal phase after triggering ovulation with gonadotropin-releasing hormone agonist in high-responder patients.

Problem: Interleukin 8 (IL-8), vascular endothelial growth factor A (VEGFA), its receptors 1 (VEGFR1) and 2 (VEGFR2) are associated with ovarian hyperstimulation syndrome (OHSS) pathophysiological mechanisms. The aim of this study was to evaluate the concentrations of these cytokines depending on the way of ovulation triggering.

Method Of Study: A total of 51 high-responder patients underwent IVF program and received gonadotropin-releasing hormone agonists (GnRHa) trigger + 1500 IU human chorionic gonadotropin (hCG) support on the oocyte pick-up (OPU) day (group I), dual trigger (GnRHa + 1500 IU hCG; group II), or hCG trigger 10,000 IU (group III) for the final oocyte maturation.

Mannose-binding lectin codon 54 genetic polymorphism and vaginal protein levels in women with gynecologic malignancies.

Objectives: Mannose-binding lectin (MBL), an innate immune system component that binds to carbohydrates, activates the complement cascade and promotes destruction of microorganisms and abnormal cells. We determined whether a polymorphism in the MBL gene influences vaginal MBL protein concentrations and the occurrence of gynecologic malignancies.

Study Design: DNA from 289 women seen in a gynecologic oncology practice and from 126 healthy women was tested for an MBL codon 54 single nucleotide polymorphism by polymerase chain reaction and endonuclease digestion.

Differential vaginal expression of interleukin-1 system cytokines in the presence of Mycoplasma hominis and Ureaplasma urealyticum in pregnant women.

Objective: The genital mycoplasmas, Ureaplasma urealyticum and Mycoplasma hominis, are commonly identified in the vagina of healthy pregnant women. However, these microorganisms are the most common isolates from the amniotic fluids of women in preterm labor. The mechanisms responsible for vaginal colonization and ascent to the uterus remain undetermined.

Mycoplasma hominis and Ureaplasma urealyticum in midtrimester amniotic fluid: association with amniotic fluid cytokine levels and pregnancy outcome.

Objective: The association between the detection of Mycoplasma hominis or Ureaplasma urealyticum in midtrimester amniotic fluid and amniotic fluid cytokine concentrations and subsequent pregnancy outcome were examined.

Study Design: Amniocentesis was performed between 15 and 19 weeks of gestation in 179 asymptomatic women. Aliquots were assayed for M hominis and U urealyticum by polymerase chain reaction coupled to enzyme-linked immunosorbent assay.

Cell-free 27 kDa heat shock protein (hsp27) and hsp27-cytochrome c complexes in the cervix of women with ovarian or endometrial cancer.

Antibodies to the 27 kDa heat shock protein (hsp27) are present in some women with ovarian and endometrial cancers but not in women with nonmalignant conditions or healthy women. The appearance of these antibodies suggests that the corresponding protein (hsp27) may be present in an extracellular form in gynecologic cancer patients. Synthesis of hsp27 is upregulated in gynecologic cancers and inhibits induction of apoptosis.
