Introduction: This study aimed to examine the immunity level against rubella in pregnant women of different birth cohorts. Methods: In total, 512 pregnant women who visited a primary clinic between May 2019 and March 2020 were enrolled. Information in terms of the patients’ hemagglutination inhibition (HI) titers, birthdate, obstetrical history, and vaccination history were collected. Participants were divided into three generational groups according to the vaccination policy in Japan. Publicly funded vaccination was administered twice as part of a routine program in group A (n = 11), once as part of a routine program and once in a catch-up program in group B (n = 181), and once in group C (n = 320). Results: All groups had some women with negative rubella HI antibody titers (7.6% of all the women, 18.2% of group A, 9.4% of group B, and 6.3% of group C) and those with rubella HI antibody titers of ≤1:16 (45.1% of all women, 90.9% of group A, 56.4% of group B, and 37.2% of group C). Rubella HI antibody titers differed between the groups; group C had higher titers than that in group B. In groups B and C, the proportions of women with rubella HI antibody titers of ≤1:16 were not statistically different between primipara and multipara. Conclusions: Our study showed that an increase in immunity to rubella, a vaccine-preventable disease, is nevertheless required among childbearing women to prevent rubella and congenital rubella syndrome.

Syphilis is a sexually transmitted disease caused by <i>Treponema pallidum</i>. Congenital syphilis occurs as a result of vertical transmission from a mother to the fetus. The number of congenital syphilis cases has recently been rising in both the United States and Japan. Vertical transmission of syphilis can be prevented by early detection during pregnancy and adequate treatment of the mother. Here we report two cases of very low birth weight infants with congenital syphilis, who had different clinical courses. One survived and developed normally following successful antibiotic treatment, while the other died at 14 hours of age with <i>Treponema pallidum</i> infection in the placenta and multiple organs.

Aim: To investigate the effects of Mycoplasma/Ureaplasma cultured in amniotic fluid on perinatal characteristics in preterm delivery between 22 and 33 weeks of gestation. Methods: The study was conducted in a tertiary perinatal center and involved 38 pregnant women who had undergone amniocentesis to evaluate intrauterine infection due to preterm labor or premature rupture of membranes. The subjects were divided into three groups based on the culture results: negative (Negative Group, n = 24), positive for Mycoplasma/Ureaplasma (M/U Group, n = 6), and positive for other pathogens (Other Pathogens Group, n = 8). One-way analysis of variance was used to compare the three groups. Results: The incidence of histological chorioamnionitis and neonatal sepsis was significantly different among the three groups (the Negative Group and the Other Pathogens Group, P < 0.01; the M/U Group and the Other Pathogens Group, P = 0.03). In the M/U Group, no infants had sepsis, severe intraventricular hemorrhage, cystic periventricular leukomalacia, or poor neurological outcomes, but one infant developed bronchopulmonary dysplasia and needed home oxygen treatment. Although one died of gastrorrhexis, the remaining five patients had normal brain magnetic resonance imaging findings and developed normally. Conclusion: The presence of Mycoplasma/Ureaplasma isolated from amniotic fluid did not cause neonatal sepsis or poor prognosis. In some infants, there was no histological chorioamnionitis in the placenta. These pathogens thus seem to be less invasive than any other microbes with respect to perinatal outcomes.

Purpose: we aimed to estimate the anxiety levels of pregnant women following maternal serum screening for CMV infection. Materials and methods: In this case-control study conducted from April 2016 to June 2017, we enrolled all pregnant women referred to our hospital who were CMV immunoglobulin (Ig) M antibody positive (IgM-positive group, n = 51); further, those who were CMV IgG positive but IgM negative (IgM-negative group, n = 51) during the same period were included as study controls. Data were collected on patient characteristics, CMV IgM levels, and whether patients were accompanied by their partners during the first hospital visit after CMV IgM testing. The State-Trait Anxiety Inventory was used to assess anxiety levels. Results: Both groups were age matched [mean age (years): IgM-positive, 30 ± 4.2 and IgM-negative, 29.9 ± 4.6]. The mean state-anxiety score was higher in the IgM-positive group (53 ± 9.6) than in the IgM-negative group (38.5 ± 7.0, p <.05) with no between-group differences in trait-anxiety scores. Similarly, a higher number of women were accompanied by their partners in the IgM-positive group. The state-anxiety scores and CMV IgM levels were not correlated in the IgM-positive group. Conclusion: Counseling support is essential for IgM-positive pregnant women following serum screening, and the screening should be avoided if support systems are unavailable.
