The Alabama Preterm Birth Study: diffuse decidual leukocytoclastic necrosis of the decidua basalis, a placental lesion associated with preeclampsia, indicated preterm birth and decreased fetal growth.
Laminar necrosis, a band-like distribution of coagulative necrosis, has been reported at the choriodecidual interface of the free membranes of placentas of women with various adverse neonatal outcomes. Our goal in this study was to evaluate the frequency of an equivalent feature in the decidua basalis, diffuse decidual leukocytoclastic necrosis (DDLN), a diffuse coagulative necrosis admixed with karyorrhectic debris, in preterm births <32 weeks, and to determine its association with various obstetric conditions, markers of placental inflammation, and newborn outcome. ⋯ DDLN of the decidua basalis is relatively common in placentas of 23-32 week newborns, and, when present, is inversely associated with inflammatory maternal and newborn conditions and positively associated with preeclampsia, indicated preterm birth, and lower birth weight. The positive correlation of DDLN with obstetrical and neonatal conditions associated with underperfusion of the placental bed, suggests that DDLN may be a marker of vascular compromise.
