PROBLEM: To determine the changes of pentraxin 3 (PTX3) level in noninvasively obtained cervical fluid samples from women with preterm prelabor rupture of membranes (PPROM) based on the presence of microbial invasion of the amniotic cavity (MIAC) and/or intra-amniotic inflammation (IAI), and intra-amniotic infection (the presence of both MIAC and IAI). METHODS OF STUDY: A total of 160 women with PPROM were included. Cervical fluid samples were obtained using a Dacron polyester swab and amniotic fluid samples were obtained by transabdominal amniocentesis. Cervical fluid PTX3 levels were assessed using enzyme-linked immunosorbent assay. RESULTS: PTX3 was found in all the cervical fluid samples and its levels were higher in women with MIAC, IAI, and intra-amniotic infection than in women without these conditions. When the women were categorized into four subgroups based on the presence of MIAC and/or IAI, women with intra-amniotic infection had higher cervical fluid PTX3 levels than those with sterile IAI (IAI alone), colonization (MIAC alone), or no MIAC or IAI. A cervical fluid PTX3 level of 11 ng/mL was the best value for identifying the presence of intra-amniotic infection in women with PPROM. CONCLUSIONS: PTX3 is a constituent of cervical fluid of women with PPROM. Cervical fluid PTX3 level reflects the situation in the intra-amniotic compartments of women with PPROM. Cervical fluid PTX3 is a potential marker for the noninvasive identification of intra-amniotic infection in PPROM.
