Abstract
Urogenital infections are extremely prevalent during pregnancy and are an important cause of premature labor. However, the prevalence of urogenital infections during childbirth is not well known. Objective. Identify urogenital infections present at the beginning of labor in both full-term and preterm pregnancies. Study Design. Ninety-four women were admitted to the inpatient maternity clinic of the Federal University of Rio Grande do Norte (UFRN). In total, 49 women in preterm labor and 45 women in full-term labor were included in the study, and samples of urinary, vaginal, and perianal material were collected for microbiological analysis. Results. The prevalences of general infections in the preterm labor group and the full-term labor group were 49.0% and 53.3% (P = 0.8300), respectively. Urogenital infections in the preterm and full-term labor groups included urinary tract infection in 36.7% and 22.2% of women, vaginal candidiasis in 20.4% and 28.9% of women, bacterial vaginosis in 34.7% and 28.9% of women, and group B streptococcus in 6.1% and 15.6% of women, respectively. Conclusions. Urogenital infections were prevalent in women in preterm labor and full-term labor; however, significant differences between the groups were not observed.
Highlights
Urogenital infections (UGIs) are prevalent during pregnancy and are recognized as an important cause of premature labor
Bacterial vaginosis (BV), vulvovaginal candidiasis (VC), and trichomoniasis are responsible for 90% of cases of infectious vulvovaginitis, which can lead to gynecological and obstetrical complications such as pelvic inflammatory disease, postabortion endometritis, chorioamnionitis, and premature labor [3, 4]
BV was identified according to the Amsel criteria, and VC was diagnosed by analyzing vaginal smears
Summary
Urogenital infections (UGIs) are prevalent during pregnancy and are recognized as an important cause of premature labor. The presence of pathogenic bacteria in the bladder of pregnant women is associated with the mass colonization of the inferior genital tract and the presence of chorioamnionitis, even when the infection is subclinical [11]. Many studies have demonstrated the importance of adequate maternal diagnosis and treatment for the reduction of the vertical transmission of BGS and early-onset neonatal sepsis [13]. Adequate diagnosis and treatment of urogenital infections during the prenatal period is necessary; the prevalence of infections during labor must be studied, and the importance of these infections in determining the outcome of pregnancy and the health of the newborns must be evaluated
