- The study aimed to determine the cervical calreticulin and cathepsin-G concentrations in pregnancies complicated by preterm prelabor rupture of membranes (PPROM) with respect to the presence of microbial invasion of the amniotic cavity (MIAC) and intra-amniotic inflammation (IAI).Eighty women with singleton pregnancies complicated by PPROM were included in this study. Cervical and amniotic fluids were obtained at the time of admission, and concentrations of calreticulin and cathepsin-G in cervical fluid were determined using ELISA. The MIAC was defined as a positive PCR analysis for Ureaplasma species, Mycoplasma hominis, and/or Chlamydia trachomatis and/or by positivity for the 16S rRNA gene. IAI was defined as amniotic fluid bedside IL-6 concentrations ≥745pg/mL Result: Neither women with MIAC nor with IAI had different cervical fluid concentrations of calreticulin (with MIAC: median 18.9pg/mL vs. without MIAC: median 14.7pg/mL, p=0.28; with IAI: median 14.3pg/mL vs. without IAI: median 15.6pg/mL, p=0.57;) or of cathepsin-G (with MIAC: median 30.7pg/mL vs. without MIAC: median 24.7pg/mL, p=0.28; with IAI: median 27.3pg/mL vs. without IAI: median 25.1pg/mL, p=0.80) than women without those complications. No associations between amniotic fluid IL-6 concentrations, gestational age at sampling, and cervical fluid calreticulin and cathepsin-G concentrations were found.Cervical fluid calreticulin and cathepsin-G concentrations did not reflect the presence of MIAC or IAI in women with PPROM.

- 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).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.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.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.

- We evaluated the levels of cell-free nuclear DNA (nDNA) and cell-free mitochondrial DNA (mtDNA) in the amniotic fluid supernatant from pregnancies complicated by preterm prelabor rupture of membranes (PPROM) based on evidence of microbial invasion of the amniotic cavity (MIAC) and/or intra-amniotic inflammation (IAI).A total of 155 women with PPROM were included in this study. Amniotic fluid samples were obtained by transabdominal amniocentesis. The levels of cell-free nDNA and mtDNA in the amniotic fluid supernatant were assessed and quantified by real-time polymerase chain reaction.The levels of cell-free nDNA and mtDNA were higher in women with MIAC and IAI than in women without these conditions (nDNA: with MIAC: median 3.9×104 genome equivalent [GE]/mL vs without MIAC: median 1.2×104 GE/mL, with IAI: median: 5.3×104 GE/mL vs without IAI: median 1.2×104 GE/mL; mtDNA: with MIAC: median 9.2×105 GE/mL vs without MIAC: median 2.5×105 GE/mL, with IAI: median 1.1×106 GE/mL vs without IAI: median 2.5×105 ; all P values≤0.01). Women with the microbial-associated IAI showed the highest levels of cell-free nDNA and mtDNA.Cell-free nDNA and mtDNA are constituents of the amniotic fluid supernatant from PPROM pregnancies. Both cell-free nDNA and mtDNA are involved in the intra-amniotic inflammatory response in women with PPROM.

- Abstract Objective: To determine the cervical fluid interleukin (IL)-6 and IL-8 levels in pregnancies complicated by preterm prelabor rupture of membranes (PPROM) and the association of these interleukins with microbial invasion of the amniotic cavity (MIAC) and histological chorioamnionitis (HCA). Methods: Sixty women with singleton pregnancies were included in this study. Cervical fluid was sampled at the time of admission using Dacron polyester swabs, which were placed into the endocervical canal for 20s. IL-6 and IL-8 levels were determined by ELISA. The management of PPROM was active management (except for in pregnancies <28 weeks of gestation) and occurs not later than 72h after the rupture of membranes. Result: The women with MIAC had higher IL-6 and IL-8 levels than did the women without MIAC (IL-6: p=0.01; IL-8: p=0.003). There was no difference in IL-6 levels between women with and without HCA (p=0.37). The women with HCA had higher IL-8 levels only in the crude analysis (p=0.01) but not after adjustment for gestational age (p=0.06). The women with both MIAC and HCA had higher levels of IL-6 and IL-8 than did the other women (IL-6: p=0.003; IL-8: p=0.001). IL-8 level of 2653pg/mL was found to be the best cut-off point in the identification of PPROM pregnancies complicated by both MIAC and HCA with a likelihood ratio of 24. Conclusions: The presence of MIAC is the most important factor impacting the local cervical inflammatory response, which is determined by IL-6 and IL-8 levels in the cervical fluid. IL-8 levels seem to be a promising non-invasive marker for the prediction of pregnancies complicated by the presence of both MIAC and HCA.

- The primary aim of this study was to identify the association between the local inflammatory response in gingival crevicular fluid measured by the levels of multiple proteins and maternal and intra-amniotic inflammatory responses measured by maternal serum C-reactive protein (CRP) and amniotic fluid interleukin (IL)-6 concentrations, respectively, in women with preterm prelabor rupture of membranes (PPROM).A prospective study was performed in which 78 women with singleton pregnancies complicated by PPROM between 24+0 and 36+6 weeks of gestation were included. Transabdominal amniocenteses were performed at the time of admission. A bedside assessment of amniotic fluid IL-6 was performed. Maternal serum CRP concentration was also measured at the time of admission. Gingival crevicular fluid was collected from the pocket of the selected tooth (the tooth with the deepest pocket) using standard sterile paper strips within 72h after admission. Twenty-six proteins in the gingival crevicular fluid were assessed by multiplex the Meso-Scale technology.No correlations between the levels of proteins in the gingival crevicular fluid and maternal serum CRP and amniotic fluid IL-6 concentrations were found, except for a weak positive correlation between granulocyte macrophage colony-stimulating factor and CRP.The local inflammatory response in the gingival crevicular fluid is not related to the maternal and intra-amniotic inflammatory responses in women with PPROM.

- The aim of this study was to evaluate the amniotic fluid cathepsin-G concentrations in women with preterm prelabor rupture of membranes (PPROM) based on the presence of the microbial invasion of the amniotic cavity (MIAC) and/or intra-amniotic inflammation (IAI).A total of 154 women with singleton pregnancies complicated by PPROM were included in this study. Amniotic fluid samples were obtained by transabdominal amniocentesis. Amniotic fluid cathepsin-G concentrations were assessed by ELISA. MIAC was determined using a non-cultivation approach. IAI was defined as an amniotic fluid bedside interleukin-6 concentration≥745pg/mL.Women with MIAC had higher amniotic fluid cathepsin-G concentrations than women without MIAC (with MIAC: median 82.7ng/mL, versus without MIAC: median 64.7ng/mL; p=0.0003). Women with IAI had higher amniotic fluid cathepsin-G concentrations than women without this complication (with IAI: median 103.0ng/mL, versus without IAI: median 66.2ng/mL; p<0.0001). Women with microbial-associated (with both MIAC and IAI) IAI and sterile (IAI without MIAC) IAI had higher amniotic fluid cathepsin-G concentrations than women with colonization (MIAC without IAI) and women without both MIAC and IAI (p<0.0001).The presence of either microbial-associated or sterile IAI was associated with increased amniotic fluid cathepsin-G concentrations in pregnancies complicated by PPROM. Amniotic fluid cathepsin-G appears to be a potential marker of IAI.

- The aim of this study was to evaluate clusterin concentrations in amniotic fluid in pregnancies complicated by preterm prelabor rupture of membranes (PPROM) with respect to the presence of the microbial invasion of the amniotic cavity (MIAC), intra-amniotic inflammation (IAI) and microbial-associated IAI.One hundred thirty-six women with singleton pregnancies complicated by PPROM were included in this study. Amniotic fluid samples were obtained by transabdominal amniocentesis. Amniotic fluid clusterin concentrations were assessed by enzyme-linked immunosorbent assay. MIAC was determined by a non-cultivation approach. IAI was defined as an amniotic fluid bedside interleukin-6 concentration≥745pg/mL. Microbial-associated IAI was characterized as the presence of both MIAC and IAI.Women with MIAC, IAI and microbial-associated IAI had lower amniotic fluid clusterin concentrations than women without these complications (with MIAC: median 1314ng/mL versus without MIAC: median 1633ng/mL, p=0.003; with IAI: median 1281ng/mL versus without IAI: median 1575ng/mL, p=0.04; with microbial associated-IAI: median 1220ng/mL versus without microbial-associated IAI: median 1575pg/mL; p=0.008). A week negative correlation between amniotic fluid clusterin concentrations and gestational age at sampling was revealed (rho=-0.30; p=0.0005).The presence of MIAC, IAI and microbial-associated IAI was characterized by lower amniotic fluid clusterin concentrations in pregnancies complicated by PPROM.

- In this study, pentraxin 3 (PTX3), C-reactive protein (CRP), and serum amyloid P component (SAP) concentrations in the amniotic fluid of women with preterm pre-labor rupture of membranes (PPROM) were evaluated based on evidence of microbial invasion of the amniotic cavity (MIAC), intra-amniotic inflammation (IAI), and microbial-associated IAI. A total of 149 women with PPROM were included in this study. Amniotic fluid samples were obtained by transabdominal amniocentesis. Amniotic fluid PTX3, SAP, and CRP concentrations were assessed using enzyme-linked immunosorbent assay. PTX3 and CRP concentrations were higher in women with MIAC, IAI, and microbial-associated IAI than in women without these conditions. SAP concentrations were only higher in the presence of IAI and microbial-associated IAI. Amniotic fluid PTX3 concentrations of 11ng/mL were found to be the best value for identifying the presence of microbial-associated IAI and IAI in women with PPROM. To conclude, amniotic fluid pentraxins are involved in intra-amniotic inflammatory responses in pregnancies complicated by PPROM.
