Abstract
Studies have shown that triggering receptor expressed on myeloid cells-1 (TREM-1) is the mediator and activator of neutrophils and monocytes after stimulation with lipopolysaccharide (LPS), heat-inactivated Gram (-) bacteria, Gram (+) bacteria or fungi. Different studies have measured the expression of TREM-1 in patients with bacterial infections and critical states. The purpose of this study was to evaluate the expression of TREM-1 in circulating maternal leukocytes in premature rupture of the membranes (PRM). Two groups of patients were included in this case control study: pregnant women with PRM and healthy controls. All patients were free of any infection, including cervix and urinary tract. Although all patients expressed TREM-1 to some extent, there was no statistically significant difference in the expression of different cellularities in both groups; except for the mononuclear leukocytes (p < 0.05). In this study, TREM-1 was not altered in PRM.

Abstract
Maternal nutrition is an important determinant of one-carbon metabolism and defects in the one-carbon metabolism may lead to poor obstetric outcomes. This study was designed to test the hypothesis that altered intake/metabolism of micronutrients (folic acid and vitamin B12) and docosahexaenoic acid (DHA) contributes to increased homocysteine and oxidative stress leading to altered levels of matrix metalloproteinases (MMPs) and tissue inhibitors of metalloproteinases (TIMPs) in women delivering preterm. We have earlier reported increased vitamin B12, homocysteine, and oxidative stress along with reduced placental DHA in women delivering preterm. In this study, we further examine the placental levels of MMP2, MMP3, TIMP1, and TIMP2 in 75 women delivering at term and 73 women delivering preterm. Placental levels of MMPs and TIMPs were determined by ELISA. Placental MMP2 and MMP3 levels were higher (P<0.01) in women delivering preterm as compared with term. There was no difference in the placental TIMP1 and TIMP2 levels in women delivering preterm and at term. Further placental MMP2 and MMP3 levels were higher (P<0.01) in women with preterm labor as compared with those in labor at term, suggesting that MMPs may favor degradation of extracellular matrix in the placenta during preterm labor. Our study for the first time suggests a crucial role of micronutrients and MMPs in preterm birth. Future studies need to examine if epigenetic modifications through the one-carbon cycle contribute to increased levels of MMPs leading to preterm deliveries.

Abstract
BACKGROUND Matrix metalloproteinases (MMPs) are involved in remodeling of the extracellular matrix (ECM) during pregnancy and parturition. Aberrant ECM degradation by MMPs or an imbalance between MMPs and their tissue inhibitors (TIMPs) have been implicated in the pathogenesis of preterm labor, however few studies have investigated MMPs or TIMPs in maternal serum. Therefore, the purpose of this study was to determine serum concentrations of MMP-3, MMP-9 and all four TIMPs as well as MMP:TIMP ratios during term and preterm labor. METHODS A case control study with 166 singleton pregnancies, divided into four groups: (1) women with preterm birth, delivering before 34 weeks (PTB); (2) gestational age (GA) matched controls, not in preterm labor; (3) women at term in labor and (4) at term not in labor. MMP and TIMP concentrations were measured using Luminex technology. RESULTS MMP-9 and TIMP-4 concentrations were higher in women with PTB vs. GA matched controls (resp. p = 0.01 and p<0.001). An increase in MMP-9:TIMP-1 and MMP-9:TIMP-2 ratio was observed in women with PTB compared to GA matched controls (resp. p = 0.02 and p<0.001) as well as compared to women at term in labor (resp. p = 0.006 and p<0.001). Multiple regression results with groups recoded as three key covariates showed significantly higher MMP-9 concentrations, higher MMP-9:TIMP-1 and MMP-9:TIMP-2 ratios and lower TIMP-1 and -2 concentrations for preterm labor. Significantly higher MMP-9 and TIMP-4 concentrations and MMP-9:TIMP-2 ratios were observed for labor. CONCLUSIONS Serum MMP-9:TIMP-1 and MMP-9:TIMP-2 balances are tilting in favor of gelatinolysis during preterm labor. TIMP-1 and -2 concentrations were lower in preterm gestation, irrespective of labor, while TIMP-4 concentrations were raised in labor. These observations suggest that aberrant serum expression of MMP:TIMP ratios and TIMPs reflect pregnancy and labor status, providing a far less invasive method to determine enzymes essential in ECM remodeling during pregnancy and parturition.

Abstract
OBJECTIVE This study was conducted to examine the frequency and clinical significance of a positive Amnisure test in patients with preterm labor and intact membranes by sterile speculum exam. STUDY DESIGN A retrospective cohort study was performed including 90 patients with preterm labor and intact membranes who underwent Amnisure tests prior to amniocentesis (< 72 h); most patients (n=64) also underwent fetal fibronectin (fFN) tests. Amniotic fluid (AF) was cultured for aerobic/anaerobic bacteria and genital mycoplasmas and assayed for matrix metalloproteinase-8. RESULTS (1) the prevalence of a positive Amnisure test was 19% (17/90); (2) patients with a positive Amnisure test had significantly higher rates of adverse pregnancy and neonatal outcomes (e.g., impending preterm delivery, intra-amniotic infection/inflammation, and neonatal morbidity) than those with a negative Amnisure test; (3) a positive test was associated with significantly increased risk of intra-amniotic infection and/or inflammation, delivery within 7, 14, or 28 days and spontaneous preterm birth (< 35 weeks) among patients with a negative fFN test. CONCLUSIONS A positive Amnisure test in patients with preterm labor and intact membranes is a risk factor for adverse pregnancy outcome, particularly in patients with a negative fFN test. A positive Amnisure test in patients without symptoms or signs of ROM should not be taken as an indicator that membranes have ruptured.

Abstract
OBJECTIVE To examine the association between maternal and fetal genetic variants and small-for-gestational-age (SGA). METHODS A case-control study was conducted in patients with SGA neonates (530 maternal and 436 fetal) and controls (599 maternal and 628 fetal); 190 candidate genes and 775 SNPs were studied. Single-locus, multi-locus and haplotype association analyses were performed on maternal and fetal data with logistic regression, multifactor dimensionality reduction (MDR) analysis, and haplotype-based association with 2 and 3 marker sliding windows, respectively. Ingenuity pathway analysis (IPA) software was used to assess pathways that associate with SGA. RESULTS The most significant single-locus association in maternal data was with a SNP in tissue inhibitor of metalloproteinase 2 (TIMP2) (rs2277698 OR = 1.71, 95% CI [1.26-2.32], p = 0.0006) while in the fetus it was with a SNP in fibronectin 1 isoform 3 preproprotein (FN1) (rs3796123, OR = 1.46, 95% CI [1.20-1.78], p = 0.0001). Both SNPs were adjusted for potential confounders (maternal body mass index and fetal sex). Haplotype analyses resulted in associations in α 1 type I collagen preproprotein (COL1A1, rs1007086-rs2141279-rs17639446, global p = 0.006) in mothers and FN1 (rs2304573-rs1250204-rs1250215, global p = 0.045) in fetuses. Multi-locus analyses with MDR identified a two SNP model with maternal variants collagen type V α 2 (COL5A2) and plasminogen activator urokinase (PLAU) predicting SGA outcome correctly 59% of the time (p = 0.035). CONCLUSIONS Genetic variants in extracellular matrix-related genes showed significant single-locus association with SGA. These data are consistent with other studies that have observed elevated circulating fibronectin concentrations in association with increased risk of SGA. The present study supports the hypothesis that DNA variants can partially explain the risk of SGA in a cohort of Hispanic women.

Abstract
OBJECTIVES to assess the relationship between maternal and umbilical serum concentrations of matrix metalloproteinases (MMP)-2,8,9, the soluble receptor for advanced glycation end products (sRAGE) and IL-10 and premature delivery and fetal inflammation. METHODS maternal serum levels of MMPs, sRAGE, IL-10 and C-reactive protein (CRP) were determined in 67 women with preterm labor and in 38 healthy pregnant women of similar gestational age (GA). In the group with preterm labor we also determined umbilical concentrations of MMPs, IL-6 and sRAGE. The group with preterm labor was additionally divided based on the presence of funisitis and elevations of fetal umbilical IL-6 concentrations. RESULTS maternal serum levels of MMP-2 and sRAGE were significantly lower in women with preterm labor compared to women with normal pregnancy. Additionally, within the group of women with preterm labor, maternal serum MMP-2 concentrations were significantly lower in the subgroup with funisitis and in the subgroup with elevated umbilical concentration of IL-6. CONCLUSION our results demonstrate significantly different serum concentrations of MMP-2 and sRAGE in women with preterm labor compared to healthy pregnant patients of the same GA.

Abstract
BACKGROUND We have recently shown that serum relaxin-2 levels are attenuated in women with a history of recurrent pregnancy loss (RPL). We sought to determine whether a history of RPL is also associated with changes in serum matrix metalloproteases (MMPs) and tissue inhibitors of matrix metalloproteases (TIMP) -1 and -2. METHODS We obtained serum from 20 pregnant women with a history of RPL and 20 age-matched pregnant women with no history of RPL (NRPL) at 6-8, 10-12, 20, and 34 weeks gestation, and from cord blood. We quantified total serum concentrations of MMP-1, MMP-3, MMP-9 and TIMP-1 and TIMP-2 by ELISA. We determined whether these serum marker levels were associated with a history of RPL and delivery before 37 weeks gestation. RESULTS There was no difference in the rates of miscarriage, preterm birth or prelabour rupture of fetal membranes between RPL and NRPL. However babies born to RPL were lighter than those born to NRPL. Serum MMP-1, 9, and TIMP-1 did not differ between RPL and NRPL but MMP-3 was higher in RPL vs. NRPL at 6-8 weeks (P < 0.05). Serum TIMP-2 levels were higher in RPL women at all gestations (P < 0.01). The ratio of RLX-2 (reported previously) to TIMP-2 at 10-12 weeks gestation was more strongly associated with a history of RPL than either peptide separately - area under the ROC curves for RLX-2 0.79 (95% CI 0.57 to 0.92), TIMP-2 0.83 (95% CI 0.63 to 0.95), and for RLX-2:TIMP-2 ratio 0.92 (95% CI 0.74 to 0.99). CONCLUSIONS Women with a history of RPL demonstrate increased serum TIMP-2 and reduced RLX-2 during a subsequent viable pregnancy. Determination of both markers in early pregnancy enhances the discrimination of women with a history of RPL. These observations suggest roles for these two peptides in early implantation and placental development. Whether these may prove to be reliable early predictive markers for subsequent pregnancy loss in the index pregnancy is unknown and will require further studies.

Abstract
BACKGROUND AND OBJECTIVE Matrix metalloproteinases (MMPs) and their regulators are connected to periodontal inflammation and destruction. However, the presence and role of the salivary MMPs in pregnancy-related gingivitis are not well known. Our longitudinal study aimed to monitor salivary proteinase levels and possible changes, and relate them to periodontal status during pregnancy and postpartum. MATERIAL AND METHODS Salivary samples were collected from 30 periodontally healthy pregnant women five times (once during each trimester, 4-6 wk after delivery and after lactation) and, as their controls, from 24 non-pregnant women three times (during successive months). Periodontal examination included visible plaque index, bleeding on probing, probing pocket depth and clinical attachment level measurements. Matrix metalloproteinase-8 levels were measured by immunofluorometric assay, and MMP-2 and MMP-9 levels and molecular forms by gelatin zymography. Salivary elastase, myeloperoxidase and tissue inhibitor of matrix metalloproteinase-1 levels were measured by ELISA. RESULTS Elastase concentrations maintained stable during the follow-up, while myeloperoxidase concentrations increased significantly after delivery. During pregnancy, MMP-8 concentrations were significantly lower than postpartum concentrations, being lowest during the second trimester and highest after delivery, and varying inversely to pregnancy gingivitis, observed as elevated percentages of bleeding on probing and probing pocket depth during the second and third trimester. In pregnant women, the highest MMP-2 and MMP-9 levels were found in saliva after lactation. In the control group, both clinical and enzymological findings remained stable during the follow-up period. CONCLUSION Our results suggest that hormonal changes during pregnancy induce or enhance susceptibility to gingivitis, while salivary proteinase and myeloperoxidase levels are reduced.

Abstract
PROBLEM Matrix metalloproteinase (MMP) and tissue inhibitor of metalloproteinase (TIMP) play important roles throughout various stages of pregnancy, including embryo implantation, trophoblastic invasion, placentation in early gestation, and cervical dilatation in later gestation, and feto-maternal membrane lysis. It would be beneficial if assessment of serum concentrations of MMP and TIMP could predict successful implantation following in vitro fertilization-embryo transfer (IVF-ET). This study was performed to compare serum MMP and TIMP concentrations between patients with and without the establishment of pregnancy following ET. METHOD OF STUDY Ten patients who conceived and 10 patients who did not after IVF-ET were entered in the present study. Only intra-uterine single pregnancies with uneventful courses to term were included in the study subjects. Blood samples were obtained at 7, 14 and 21 days after oocyte retrieval. Serum concentrations of MMP-1, MMP-2, MMP-3, and TIMP-1 were measured using enzyme-linked immunosorbent assay. These variables were compared with estradiol (E(2)), progesterone (P(4)), and betahCG levels in the patients' sera. Clinical pregnancies were diagnosed only when fetal heartbeat was visualized on ultrasound. RESULTS There were no significant differences in serum MMP concentrations between the pregnant group and the non-pregnant group. However, serum TIMP-1 concentrations on Days 14 and 21 in the pregnant group were significantly higher than those in non-pregnant group [Day 14: 223.1 +/- 11.9 versus 177.5 +/- 20.6 ng/mL (P = 0.004); Day 21: 215.4 +/- 27.8 versus 181.5 +/- 27.4 ng/mL (P = 0.03)]. Serum TIMP-1 concentrations were also correlated with serum E(2) and P(4) levels (P < 0.0001), but not with those of the MMPs. None of MMP nor TIMP-1 were correlated with serum betahCG level. CONCLUSIONS It was demonstrated that the patients who successfully conceived after IVF-ET showed significantly higher levels of TIMP-1 at 14 and 21 days after IVF-ET, but not at day 7; further work will be required to determine if serum TIMP-1 can be used to improve prediction of pregnancy outcome in these patients.

Abstract
OBJECTIVES Matrix metalloproteinases (MMPs) are proteins that degrade the extracellular matrix and have been shown to be elevated in the urine of patients with cancer. One action of MMPs is the degradation of collagen IV that plays a role in tumor invasion and metastasis. This degradation can be measured by a fluorescent microplate activity assay that has been suggested to identify patients with renal cell carcinoma (RCC). Our aim was to confirm the utility of urinary MMP activity as a diagnostic test for RCC. METHODS Urine samples from 21 patients undergoing nephrectomy for renal masses, as well as from 2 patients undergoing retroperitoneal mass excision for presumed local recurrence, were collected. Urine samples from 47 healthy volunteers were also collected. After concentration, the urine samples were incubated with fluorescein-labeled collagen IV. The fluorescence activity in each sample was measured using a conventional fluorescent microplate reader to determine the degree of collagen IV degradation in each specimen. RESULTS Of the 21 patients undergoing nephrectomy, 15 had RCC, and both patients undergoing retroperitoneal mass excision had pathologically confirmed RCC recurrence. The mean number of fluorescence units emitted from the urine of patients with RCC was 48,924 units (range 0 to 275,879). The mean number of fluorescence units emitted from the urine of healthy patients was 29,834 units (range 0 to 400,086). This difference was not statistically significant (P = 0.34). CONCLUSIONS Despite previous evidence, urinary MMP activity was not an adequate test to identify RCC. Most normal urine samples had significant MMP activity.

Abstract
Matrix metalloproteinases belong to the key effectors of tissue remodeling in health and disease. Matrix metalloproteinases -2 and -9, the most prevalent representatives of this family, are expressed in the endometrium. Chronic endometritis concomitant with sterility and spontaneous abortions is associated with decreased content of matrix metalloproteinases in the endometrium. Chronic endometritis combined with sterility correlates with decreased serum activities of matrix metalloproteinases -2 and -9, which returns to normal after recovery. Measurements of serum activities of matrix metalloproteinases -2 and -9 are proposed for monitoring of the dynamics and treatment efficiency in chronic endometritis.

The value of cervical length and plasma proMMP-9 levels for the prediction of preterm delivery in pregnant women presenting with threatened preterm labor. Eur J Obstet Gynecol Reprod Biol 2005; 128:108-12. [PMID: 16314025 DOI: 10.1016/j.ejogrb.2005.10.022] [Citation(s) in RCA: 8] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/25/2004] [Revised: 02/15/2005] [Accepted: 10/25/2005] [Indexed: 10/25/2022]
Abstract
OBJECTIVE To assess the value of plasma proMMP-9 levels in predicting the progress of threatened preterm labor to true preterm labor and delivery within 7 days of presentation, along with the ultrasonographic measurement of cervical length. STUDY DESIGN The study included sixty two pregnant women presented in the 2nd Department of Obstetrics and Gynecology of University of Athens at Aretaieion Hospital with threatened preterm labor. On subjects' presentation, cervical length was evaluated with transvaginal ultrasonography, plasma proMMP-9 levels were measured with the use of a solid phase enzyme immunoassay, and maternal characteristics (smoking, history of preterm delivery and parity) as well as the use of tocolytics were recorded. Subjects were followed up for premature delivery within 7 days. ROC analysis for plasma proMMP-9 levels was performed and logistic regression analysis was used for the evaluation of the prognostic effect of the parameters. RESULTS The only significant predictors for establishment of true preterm labor and delivery within 7 days of presentation were cervical length (with cutoff value 15 mm: odds ratio=0.022, 95% CI=0.002-0.243, p=0.002) and plasma proMMP-9 (with cutoff value 67.15 ng/ml: odds ratio=0.035, 95% CI=0.003-0.388, p=0.006). The combination of the adopted proMMP-9 and cervical length cutoff values was characterized by a sensitivity of 90.9% and a specificity of 98.3% for predicting the progress to true preterm labor and delivery. CONCLUSION Plasma proMMP-9 levels could possibly serve as a predictive factor for the progress of threatened preterm labor to true preterm labor and delivery within 7 days of presentation, along with the ultrasonographic evaluation of cervical length.
