Elevated concentrations of interleukin-6 (IL-6), C-reactive protein (CRP), and matrix
metalloproteinase-9 (MMP-9) in fetal and neonatal compartments have been associated …

Most previous studies of maternal cytokines and preterm birth have analyzed immunologic
biomarkers after the onset of labor or membrane rupture; fewer have examined the systemic …

OBJECTIVE: The objective of this study was to determine the frequency and clinical
significance of a systemic inflammatory response as defined by an elevated plasma …

Objective: To examine the interaction of the cytokines interleukin-1 receptor antagonist (IL)-
1Ra, IL-6 and IL-10 to predict preterm birth (PTB) in pregnant Hispanic women (n= 470) …

Methods: Blood samples were collected from 130 gravidas at 22-34 weeks' gestation. The
study group consisted of 89 women evaluated for preterm contractions or premature rupture …

OBJECTIVE: Our purpose was to determine whether early second-trimester amniotic fluid
interleukin-6 levels predict delivery before 34 weeks' gestation. STUDY DESIGN: We used …

OBJECTIVE: Disorders that lead to preterm delivery influence the fetal inflammatory
response. STUDY DESIGN: We calculated odds ratios of elevated concentrations of 25 …

Objective: To determine the normal concentrations of maternal serum interleukin-6 during
the second and third trimesters of pregnancy and the different stages of term and preterm …

OBJECTIVE: This study was undertaken to evaluate the association between umbilical cord
interleukin-6 (IL-6) levels and neonatal morbidity in infants born at less than 32 weeks' …

PROBLEM: Subclinical intra‐amniotic infection is often associated with preterm delivery and
may precede it by several weeks. We tested the hypothesis that Interleukin‐6 (IL‐6) may be …
