Abstract/OtherAbstract:
OBJECTIVE: We examined the hypothesis that fetal proinflammatory cytokine release is a feature of placental vascular disease causing fetal compromise. We measured the concentrations of fetal proinflammatory cytokines interleukin 6 (IL-6), tumor necrosis factor alpha (TNF-alpha), and interleukin-8 (IL-8) in the presence of vascular disease in the umbilical placental villous circulation. Vascular disease was identified by high-resistance umbilical artery Doppler flow velocity waveform studies. METHODS: We measured levels of the inflammatory cytokines IL-6 and TNF-alpha and the chemokine IL-8 in fetal blood. Blood was collected from the umbilical vein at delivery, and serum was stored at -70C until assayed using chemiluminescent and enzyme-linked immunosorbent assay methods. We studied 36 normal pregnancies delivered by elective cesarean at term and 50 pregnancies with a high-resistance umbilical artery Doppler flow velocity waveform pattern indicative of fetal placental vascular disease delivered by elective cesarean because of potential fetal compromise. RESULTS: In the presence of umbilical placental vascular disease there were significantly higher levels of IL-6 (median 5.3 pg/mL, P <.05) and IL-8 (median 26.5 pg/mL, P <.01) compared with normal pregnancies (median value of IL-6 and IL-8 were below assay threshold). There was no difference for TNF-alpha, with the median results undetectable in both groups. CONCLUSION: We found higher concentrations of IL-6 and IL-8 in the fetal circulation in the presence of umbilical placental vascular disease.
