Prenatal exposure to intra-amniotic infection with Ureaplasma species increases the prevalence of bronchopulmonary dysplasia

OBJECTIVES: species. METHODS: spp. cultures were diagnosed with microbial invasion of the amniotic cavity (MIAC). Patients who tested positive for both intra-amniotic inflammation and MIAC were considered to have intra-amniotic infection. An umbilical vein blood IL-6 concentration >11.0 pg/mL indicated fetal inflammatory response syndrome (FIRS). The maternal inflammatory response (MIR) and fetal inflammatory response (FIR) were staged using the Amsterdam Placental Workshop Group Consensus Statement. RESULTS: spp. or intra-amniotic inflammation without MIAC. CONCLUSION: species.
