    • Objective: To determine the best prediction model of histological chorioamnionitis and funisitis in preterm prelabor rupture of membranes (PPROM) using selected candidate proteins in the amniotic fluid (AF). Material and methods: Prospective cohort study. Twenty-six AF proteins were assayed by a multiple immunoassay from 107 women with membranes rupture from 23+0 to 36+6 weeks. The Czech Republic policy is active management, and the majority of women were delivered within 72 h after the rupture of membranes, except for women with PPROM <28+0 weeks who were managed conservatively. The best predictive models to diagnose histological chorioamnionitis and funisitis were calculated by logistic regression depending on the gestational age (GA) at membrane rupture. Results: Both IL-6 and a combination of IL-10, and migration inhibiting factor (MIF) were the best predictive models of histological chorioamnionitis and funisitis, respectively, with sensitivity, specificity, positive and negative predictive values and positive likelihood ratio (LR+) of 62, 83, 37, 93 and 3.6 and of 63, 91, 53, 94 and 7.0, respectively. Depending on whether GA at membrane rupture was <32 or ≥ 32 weeks, IL-10, alone or in combination with MIF and triggering receptor expressed on myeloid cells-1, was the strongest inflammatory biomarker for funisitis (LR+10.6 and 36.6, respectively). Conclusion: Regardless of the GA at membrane rupture, IL-6 from the AF was the best predictor of histological chorioamnionitis. Amniotic fluid IL-10 was notably accurate in the prediction of funisitis.

  • Intra-amniotic inflammation predicts microbial invasion of the amniotic cavity but not spontaneous preterm delivery in preterm prelabor membrane rupture.
  • 2012
  • Ingår i: Acta obstetricia et gynecologica Scandinavica. - : Wiley. - 1600-0412 .- 0001-6349.
  • Tidskriftsartikel (refereegranskat)abstract
    • Objective. To predict microbial invasion of the amniotic cavity (MIAC) and spontaneous preterm delivery within seven days using a panel of selected proteins from amniotic fluid in a Swedish population of preterm prelabor membrane rupture (PPROM). Design. Prospective cohort study. Setting. Evaluation of intra-amniotic inflammation in preterm premature rupture of membranes. Population. Sixty-six pregnant women with preterm prelabor membrane rupture at 22(+0-) 33(+6) weeks' gestational age. Methods. Twenty-seven amniotic fluid proteins were assayed by a multiple immunoassay. Main outcome measures. The intra-amniotic inflammatory response was evaluated according to the presence of MIAC and the risk of spontaneous preterm delivery within seven days. A prediction model was constructed using logistic regression. Results. The overall rates of MIAC and spontaneous preterm delivery within seven days were 20% and 50%, respectively. There was a higher inflammatory response in women with MIAC than without. Earlier gestational age at delivery and lower birthweight were observed in the presence of microbial invasion of the amniotic cavity. Amniotic fluid Interleukin (IL)-6 and IL-10 were the best predictors of MIAC in terms of sensitivity (69%), specificity (81%), positive predictive value (47%), negative predictive value (91%) and positive likelihood ratio of 3.6. There were no differences in intra-amniotic inflammatory response according to the risk of spontaneous preterm delivery within seven days. Conclusion. Amniotic fluid IL-6 and IL-10 are the best inflammatory biomarkers to predict MIAC in women with PPROM. Intra-amniotic inflammation does not predict the occurrence of spontaneous preterm delivery within seven days of PPROM.

  • The association between selected mid-trimester amniotic fluid candidate proteins and spontaneous preterm delivery
  • 2020
  • Ingår i: Journal of Maternal-Fetal and Neonatal Medicine. - : Informa UK Limited. - 1476-7058 .- 1476-4954. ; 33:4, s. 583-592

    • Objective: The aim of this study was to explore inflammatory response and identify early potential biomarkers in mid-trimester amniotic fluid associated with subsequent spontaneous preterm delivery (PTD). Methods: A cohort study was performed at Sahlgrenska University Hospital/Östra, Gothenburg, Sweden, between 2008 and 2010. Amniotic fluid was collected from consecutive women undergoing mid-trimester transabdominal genetic amniocentesis at 14–19 gestational weeks. Clinical data and delivery outcome variables were obtained from medical records. The analysis included 19 women with spontaneous PTD and 118 women who delivered at term. A panel of 26 candidate proteins was analyzed using Luminex xMAP technology. Candidate protein concentrations were analyzed with ANCOVA and adjusted for plate effects. Results: The median gestational age at delivery was 35 + 3 weeks in women with spontaneous PTD and 40 + 0 weeks in women who delivered at term. Nominally significantly lower amniotic fluid levels of adiponectin (PTD: median 130,695 pg/mL (IQR 71,852–199,414) vs term: median 185,329 pg/mL (IQR (135,815–290,532)), granulocyte-macrophage colony stimulating factor (PTD: median 137 pg/mL (IQR 74–156) vs term: median 176 pg/mL (IQR 111–262)), and macrophage migration inhibitory factor (PTD: median 3025 pg/mL (IQR 1885–3891) vs term: median 3400 pg/mL (IQR 2181–5231)) were observed in the spontaneous PTD group, compared with the term delivery group, after adjusting for plate effects. No significant differences remained after Bonferroni correction for multiple comparisons. Conclusions: Our results are important in the process of determining the etiology behind spontaneous PTD but due to the non-significance after Bonferroni correction, the results should be interpreted with caution. Further analyses of larger sample size will be required to determine whether these results are cogent and to examine whether microbial invasion of the amniotic cavity or intra-amniotic inflammation occurs in asymptomatic women in the mid-trimester with subsequent spontaneous PTD.

  • Intraamniotic inflammatory response to bacteria: analysis of multiple amniotic fluid proteins in women with preterm prelabor rupture of membranes.
  • 2012
  • Ingår i: The Journal of Maternal-Fetal and Neonatal Medicine : the official journal of the European Association of Perinatal Medicine, the Federation of Asia and Oceania Perinatal Societies, the International Society of Perinatal Obstetricians. - : Informa UK Limited. - 1476-4954.

    • Objective: To analyse whether intraamniotic inflammation in response to bacteria is different below and above gestational age 32 weeks in pregnancies complicated by preterm prelabor rupture of membranes (PPROM). Methods: A prospective study was performed, and 115 women with singleton pregnancies complicated by PPROM at gestational ages between 24(0/7) and 36(6/7) weeks were included in the study. Transabdominal amniocenteses were performed. Amniotic fluid was analysed using polymerase chain reactions for genital mycoplasmas and cultured for aerobic and anaerobic bacteria. The concentrations of 26 proteins in the amniotic fluid were determined simultaneously using multiplex technology. Results: Bacteria were found in the amniotic fluid of 43% (49/115) of the women. The women were stratified into two subgroups according to gestational age 32 weeks. The amniotic fluid levels of four (interleukin-6, interleukin-10, CC chemokine ligands 2, and 3) and one specific (CC chemokine ligands 2) proteins were higher in women with the presence of bacteria in the amniotic fluid below and above 32 gestational weeks, respectively. Conclusions: An intraamniotic inflammatory response to bacteria in pregnancies complicated by PPROM seems to be different below and above 32 weeks of gestation.

  • Protein Concentrations of Thrombospondin-1, MIP-1β, and S100A8 Suggest the Reflection of a Pregnancy Clock in Mid-Trimester Amniotic Fluid
  • 2020
  • Ingår i: Reproductive Sciences. - : Springer Science and Business Media LLC. - 1933-7205 .- 1933-7191. ; 27:12, s. 2146-2157

    • The development of immunoassays enables more sophisticated studies of the associations between protein concentrations and pregnancy outcomes, allowing early biomarker identification that can improve neonatal outcomes. The aim of this study was to explore associations between selected mid-trimester amniotic fluid proteins and (1) overall gestational duration and (2) spontaneous preterm delivery. A prospective cohort study, including women undergoing mid-trimester transabdominal genetic amniocentesis, was performed in Gothenburg, Sweden, 2008–2016 (n = 1072). A panel of 27 proteins related to inflammation was analyzed using Meso-Scale multiplex technology. Concentrations were adjusted for gestational age at sampling, experimental factors, year of sampling, and covariates (maternal age at sampling, parity (nulliparous/multiparous), smoking at first prenatal visit, and in vitro fertilization). Cox regression analysis of the entire cohort was performed to explore possible associations between protein concentrations and gestational duration. This was followed by Cox regression analysis censored at 259 days or longer, to investigate whether associations were detectable in women with spontaneous preterm delivery (n = 47). Finally, linear regression models were performed to analyze associations between protein concentrations and gestational duration in women with spontaneous onset of labor at term (n = 784). HMG-1, IGFBP-1, IL-18, MIP-1α, MIP-1β, S100A8, and thrombospondin-1 were significantly associated with gestational duration at term, but not preterm. Increased concentrations of thrombospondin-1, MIP-1β, and S100A8, respectively, were significantly associated with decreased gestational duration after the Holm-Bonferroni correction in women with spontaneous onset of labor at term. This adds to the concept of a pregnancy clock, where our findings suggest that such a clock is also reflected in the amniotic fluid at early mid-trimester, but further research is needed to confirm this.
