Macrophage inflammatory protein 1α is a chemokine produced by various immune, epithelial, mesothelial, and fibroblast cells after exposure to bacterial lipopolysaccharide or proinflammatory molecules. The primary aim of this study was to determine MIP-1α concentrations in amniotic and cervical fluids from pregnancy with spontaneous preterm labor with intact membranes (PTL) with respect to the presence of intra-amniotic infection (both microbial invasion of the amniotic cavity and intra-amniotic inflammation) and sterile intra-amniotic inflammation (intra-amniotic inflammation alone).
The secondary aim was to assess the diagnostic indices of MIP-1α in predicting intra-amniotic infection.
