ABSTRACT Ureaplasma urealyticum is the microorganism most frequently isolated from amniotic fluids of women in preterm labor. The relationship between vaginal colonization with U. urealyticum, vaginal interleukin-1 receptor antagonist (IL-1ra) levels, and the IL-1ra genotype in pregnant women was examined. Vaginal specimens, obtained with a cotton swab from 207 women in their first trimester of pregnancy, were tested for IL-1ra concentrations by enzyme-linked immunosorbent assay and for U. urealyticum and IL-1ra genotypes by PCR. U. urealyticum was detected in 85 (41.1%) women. The median IL-1ra level was 450 ng/ml in women positive for U. urealyticum, as opposed to 225 ng/ml in women negative for this microorganism (P < 0.0001). Sixty-two percent of the 16 women who were homozygous for allele 2 of the IL-1ra gene (IL-1RN*2) were colonized with U. urealyticum, as opposed to 47% of the 49 women who were IL-1RN*1/IL-1RN*2 heterozygotes and 34% of the 133 women who were IL-1RN*1 homozygotes (P < 0.05). Median IL-1ra levels were 750 ng/ml in IL-1RN*2 homozygotes, 300 ng/ml in IL-1RN*1/IL-1RN*2 heterozygotes, and 250 ng/ml in IL-1RN*1 homozygotes (P = 0.02). The vast majority of subjects had an uneventful pregnancy and delivered a healthy infant at term. The IL-1ra genotype or U. urealyticum colonization was unrelated to birth weight. Pregnant women who are colonized with U. urealyticum during the first trimester have elevated vaginal IL-1ra concentrations and a higher prevalence of the IL-1RN*2 homozygote genotype than do noncolonized women.

The objective of the research was to study genital mycoplasma contribution to the development of reproductive disorders. Mycoplasma detection rate in genital smears of pregnant women of Khabarovsk was studied by a polymerase chain reaction (PCR) method. Ureaplasma (urealyticum+parvum) was detected in 56.3% of cases; Mycoplasma hominis in 7.5% of cases, Mycoplasma genitalium in 0% of cases. Genital mycoplasmas were detected in chorionic and fetal tissue samples in early-term spontaneous miscarriage cases, suction biopsies in women with recurrent miscarriage, tissue samples in elective abortions, placental samples of women whose pregnancy ended in preterm delivery, and placental samples of women who gave birth to children at term. Ureaplasma (urealyticum+parvum) DNA was detected in 11.9%, 18.8%, 1.4%, 32.6%, and 25.0% of cases, respectively; Mycoplasma hominis DNA in 7.4%, 12.5%, 2.6%, 2.3%, and 0% of cases, respectively; Mycoplasma genitalium DNA in 5.2%, 6.3%, 1.4%, 2.3%, 0%, respectively. Genital mycoplasmas were detected in autopsy material of children who had died in neonatal and postnatal periods. Relationship between mycoplasma concentration in vaginal flora of pregnant women and preterm delivery was identified using real-time PCR. Mycoplasma detection rate in reproductive pathologies was found to be significantly higher than in control groups. The results of the study favor the view of etiopathogenetic role of mycoplasmas in development of complications and outcomes of pregnancy.
