Introduction:
Ureaplasma (U.) and Mycoplasma (M.) species have been related to pregnancy complications (including preterm birth) and worse neonatal outcomes. The aim of our work is to evaluate neurodevelopmental outcomes in preterm infants born to mothers with Ureaplasma/Mycoplasma colonization during pregnancy.
Methods:
Preterm infants with gestational age (GA) of ≤ 30 weeks were included in a retrospective follow-up study. To evaluate the effects of maternal vaginal colonization, we divided preterm infants into two groups: exposed and unexposed infants. All infants were assessed at 24 ± 3 months of age using Griffith's Mental Developmental Scales (GMDS).
Results:
Among 254 preterm infants, only 32 infants (12.6%) were exposed to U. /M. colonization during pregnancy. Exposed infants and unexposed ones had a similar Griffith's Developmental Quotient (106 ± 27.2 vs. 108.9 ± 19.5, respectively), without significant differences (p = 0.46). However, exposed infants had a significantly poorer outcome than their unexposed peers in terms of locomotor abilities (100.7 ± 28.3 exposed vs. 111.5 ± 26.1 unexposed, p = 0.03).
Conclusion:
For visual and hearing impairment, exposed and unexposed infants had similar incidences of cognitive and motor impairment. However, exposed infants had significantly lower locomotor scores than unexposed peers.
Insights
Maternal Ureaplasma/Mycoplasma colonization in pregnancy was linked to poorer neurodevelopmental outcomes in preterm infants, specifically affecting locomotor abilities. This highlights potential risks for infant development following such infections during gestation.
Area of Science:
- Neonatal development
- Microbiology
- Obstetrics
Background:
- Ureaplasma and Mycoplasma species are associated with pregnancy complications and adverse neonatal outcomes.
- Maternal colonization may impact fetal development and long-term health.
- Understanding these effects is crucial for improving neonatal care.
Purpose of the Study:
- To assess neurodevelopmental outcomes in preterm infants born to mothers with Ureaplasma/Mycoplasma colonization.
- To identify specific areas of development affected by maternal colonization.
- To evaluate the impact on infants born at ≤ 30 weeks gestational age.
Main Methods:
- Retrospective follow-up study of preterm infants (≤ 30 weeks gestational age).
- Infants categorized into exposed (maternal colonization) and unexposed groups.
- Neurodevelopmental assessment at 24 ± 3 months using Griffith's Mental Developmental Scales (GMDS).
Main Results:
- 12.6% of 254 preterm infants were exposed to Ureaplasma/Mycoplasma.
- No significant difference in overall Griffith's Developmental Quotient between exposed (106) and unexposed (108.9) infants.
- Exposed infants showed significantly poorer locomotor scores (100.7) compared to unexposed infants (111.5).
Conclusions:
- Maternal Ureaplasma/Mycoplasma colonization did not significantly affect overall neurodevelopmental scores in preterm infants.
- Locomotor abilities were significantly impaired in infants exposed to maternal colonization.
- Further research is needed to understand the mechanisms and long-term implications of these findings.

Development of Immunocompetence
The initial cells that migrate from the fetal thymus settle within the skin and epithelial tissues lining the mouth, digestive tract, and in females, the uterus and vagina. These cells, including skin-based dendritic cells, serve as antigen-presenting cells, playing a key role in T cell activation.
