Sato M et al. - The authors found no significant differences in stages of chorioamnionitis between infants with and without neonatal diseases except for respiratory distress syndrome. A significant inverse relationship was observed between the stage of chorioamnionitis and development of respiratory distress syndrome.
Methods
The authors reviewed the neonatal intensive care unit discharge files and placental pathology reports of 302 preterm infants.
The presence of various stages of chorioamnionitis as well as absence of an association with chorioamnionitis (non-chorioamnionitis) were compared among neonatal diseases.
Results
Preterm infants were grouped according to three stages of chorioamnionitis or the absence of an association with chorioamnionitis.
Gestational age differed significantly between these groups. Before controlling for gestational age, the chorioamnionitis stage was significantly higher among infants with chronic lung disease, retinopathy of prematurity and intraventricular hemorrhage than in infants without these diseases.
The chorioamnionitis stage was lower in infants with respiratory distress syndrome than without.
After controlling for gestational age, the stage of chorioamnionitis was significantly lower in infants with respiratory distress syndrome than in infants without respiratory distress syndrome, whereas, significant differences were not detected between the presence and absence of chronic lung disease, retinopathy of prematurity and intraventricular hemorrhage.
