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.

[Ovarian overstimulation syndrome: problem of intensive care].

Ovarian hyperstimulation syndrome (OHSS) is an iatrogenic complication, the basis for which is a hyperergic uncontrolled ovarian response to gonadotropins in the ovulation stimulation cycles and assisted procreation programs. The clinical picture of OHSS is characterized by a broad spectrum of clinical and laboratory manifestations: increased vascular permeability resulting in the excess release of liquid into the third space and its storage with the development of hypovolemia, hemoconcentration, oliguria, hypoproteinemia, electrolyte imbalance, polyserositis; in severe cases, acute renal failure, thromboembolic events, and adult respiratory distress syndrome develop. The goal of treatment is to prevent the development of multiply organ dysfunctions.

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.

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.

IgA antibodies to the 27-kDa heat-shock protein in the genital tracts of women with gynecologic cancers.

Heat-shock proteins promote cell survival under adverse environmental conditions. Synthesis of the 27-kDa (HSP27), 70-kDa (HSP70), and 90-kDa (HSP90) heat-shock proteins is increased in malignantly transformed cells and has been associated with tumor proliferation, metastasis, and resistance to chemotherapeutic agents. The increased expression of heat-shock proteins and their association with tumor-specific antigens may result in local immunity to the heat-shock proteins.

Serum antibodies to the 27-kd heat shock protein in women with gynecologic cancers.

Objectives: Among women the association between heat shock protein immunity and cancer has been examined primarily for breast cancer. Autoantibodies to the 27-kd heat shock protein were detected in some patients with breast cancer but not in control subjects, and the presence of these antibodies was correlated with improved survival. We examined the relationship between autoimmunity to heat shock proteins and the diagnosis of malignancies of the female genital tract.

Heat shock protein expression during gametogenesis and embryogenesis.

When cells are subjected to various stress factors, they increase the production of a group of proteins called heat shock proteins (hsp). Heat shock proteins are highly conserved proteins present in organisms ranging from bacteria to man. Heat shock proteins enable cells to survive adverse environmental conditions by preventing protein denaturation.

Vaginal heat shock protein expression in symptom-free women with a history of recurrent vulvovaginitis.

Objectives: The cause of recurrent vulvovaginitis remains unexplained in most cases. Heat shock protein synthesis is induced under conditions of stress; its presence in vaginal samples from women who were between episodes of recurrent vulvovaginitis thus might reflect a persistent perturbation in the local milieu.

Study Design: We undertook an evaluation by means of enzyme-linked immunosorbent assay of 60-kd heat shock protein and inducible 70-kd heat shock protein expressions in vaginal wash samples from 24 symptom-free women with a history of recurrent vulvovaginitis and 19 matched control subjects.

Chlamydia trachomatis Infection, Immunity, and Pregnancy Outcome.

Chlamydia trachomatis can ascend from the cervix to the fallopian tubes and survive for long periods of time without causing symptoms. The immune response to infection clears the extracellular organisms but leads to development of a persistent intracellular infection. Repeated cycles of productive infection and persistence eventually induce tubal occlusion and infertility.
