Characteristics of adaptive responses and status of newborns depending on degree of parturient genital colonization with Ur. Urealyticum

Aim. To study the characteristic features of newborn status depending on the level of parturient genital colonization with Ur. urealyticum.

Materials and methods. The characteristic features of newborns’ status were studied in 112 puerperas, who by the results of repeated microbiological examination for ureaplasmosis, in the period of 30–34 weeks of pregnancy were divided into 3 groups: group I included 38 persons with negative results of PCR and bacteriology; group II (risk) joined 39 women, infected with Ur. urealyticum to 10⁴ CFU/ml and PCR 5·10⁴ DNA copies per ml; and group III – 35 pregnant women with bacterial inoculation less than 10⁴ CFU/ml. The comparison group – 40 pregnant women, uninfected with ureaplasmas when examined for the first time.

Results. In newborn children from puerperas of risk group, Apgar scores at 1 and 5 minutes were statistically significantly lower, than in children, born from mothers of the other groups. In this group, birth of premature newborns and those with hypotrophy as well as newborns with fetal development retardation syndrome were registered significantly more often. Perinatal encephalopathy was detected in 50.0 % of newborns. When discharged from maternal home, nearly a half of infants from this group had no the initially required body mass, but in the other groups there were 2–2.5 times more such newborns.

Conclusions. Newborns from mothers infected with Ur. Urealyticum in high, etiologically significant titers, are characterized by decrease in adaptive responses that is proved by Apgar scores and by retarded body mass growth after birth. High level of parturient genital colonization with Ur. urealyticum has a negative effect on the newborns’ health status. Low, etiologically insignificant Ur. urealyticum titers in mothers practically don’t influence the newborns’ health status.
