Perinatal listeriosis (early-onset): correlation of antenatal manifestations and neonatal outcome

Abstract

Listeria monocytogenes is an underdiagnosed and underreported cause of congenital sepsis. Twenty mother/infant pairs from whom Listeria was isolated were studied at the University of Southern California School of Medicine and Women's Hospital during the last ten years to delineate antepartum factors indicative of a fetus at high risk for perinatal Listeria sepsis. The combination of high maternal leukocyte count, fetal tachycardia, decreased fetal heart rate variability, and, especially, the absence of intrapartum fetal heart rate accelerations was associated with a complicated course for the neonate with congenital Listeria sepsis. Intrapartum administration of antibiotics decreased fetal morbidity and mortality but did not impair recovery of the organism.
