Abstract:
OBJECTIVE: The purpose of this study was to determine whether funisitis is associated with changes in the umbilical cord plasma concentration of interleukin-6 (IL-6) and matrix metalloproteinase-8 (MMP-8), microbial invasion of the amniotic cavity and neonatal outcome. METHODS: The relationship among the presence of funisitis, IL-6 and MMP-8 concentrations in umbilical cord plasma at birth, the results of amniotic fluid culture performed within 5 days of birth was examined in 83 consecutive singleton births (20-35 weeks' gestation). Funisitis was diagnosed in the presence of neutrophil infiltration into the umbilical vessel wall or Wharton's jelly. The IL-6 and MMP-8 concentration was measured with a specific immunoassay. Amniocentesis was performed in 47 patients within 5 days of birth. RESULTS: (1) Funisitis was present in 21.7% of patients. (2) Patients with funisitis had a significant higher cord plasma IL-6 concentration, but had no significant difference in cord plasma MMP-8 concentration. (3) Clinical chorioamnionitis was more common in patients with funisitis than those without funisitis. (4) A cord plasma IL-6 > 6.34 pg/ml had a sensitivity of 77.8% and a specificity of 75.4% in the identification of funisitis. (5) No correlation between cord blood plasma IL-6 concentration and MMP-8 concentration was found. (6) There was no significant correlation between gestational age at birth and cord blood plasma MMP-8 concentrations, but there appeared to be a trend to increase of cord plasma MMP-8 concentrations as gestational ages at birth were increased. (7) Neonates with congenital sepsis had a significantly higher cord plasma IL-6 and MMP-8 concentration than those without congenital sepsis. CONCLUSION: In patient with funisitis, umbilical cord plasma IL-6 concentrations were higher than those without funisitis, but umbilical cord plasma MMP-8 concentrations had no significant difference in each group. The umbilical cord plasma IL-6 and MMP-8 can be useful as a predictor of the occurrence of congenital sepsis in preterm infant.
