Groppetti D, Pecile A, Filipe J, Riva F, Inglesi A, Kuhn PA, Giussani E, Dall’Ara P. Canine Amniotic Fluid at Birth Holds Information about Neonatal Antibody Titres against Core Vaccine Viruses. Vet Sci 2024; 11:234. [PMID: 38921981 PMCID: PMC11209429 DOI: 10.3390/vetsci11060234] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/01/2024] [Revised: 05/09/2024] [Accepted: 05/22/2024] [Indexed: 06/27/2024] Open
Abstract
There is a growing interest in the composition of amniotic fluid (AF) in both humans and animals. In addition to its nutritional and protective functions for the foetus, current knowledge demonstrates that AF also serves advanced diagnostic, prognostic, and therapeutic roles. Newborn dogs have an underdeveloped immune system, making them highly susceptible to dangerous pathogens such as canine parvovirus (CPV-2), canine infectious hepatitis virus (CAdV-1), and canine distemper virus (CDV), thus exposing them to a high risk of mortality in the first weeks of life. Immunoglobulins G (IgGs) represent the only antibody isotype capable of crossing the placenta in a small amount and have been detected also in canine AF. The primary aim of this study was to investigate the reliability of AF collected at birth as a marker of passive immunity in canine species. For this purpose, total and specific IgGs against CPV-2, CAdV-1, and CDV were investigated and quantified in both maternal plasma and AF collected at the time of caesarean section. The vaccination status of the bitches was also taken into consideration. Since the immune system can be influenced by gestational age, with preterm infants having immature innate and adaptive immunity, IgG concentrations were correlated with amniotic lecithin, sphingomyelin, cortisol, surfactant protein A, and pentraxin 3 levels. In a previous study from our group on foetal maturity these molecules were measured in the same samples. Finally, correlations between their amniotic content and neonatal outcomes were investigated. This study demonstrates that AF analysis at birth can provide valuable insights into neonatal immunity in puppies, offering a non-invasive method to detect potential early health risks, for improved puppy care and management.

Biomarkers of neutrophil extracellular traps (NETs) and nitric oxide-(NO)-dependent oxidative stress in women who miscarried. Sci Rep 2020; 10:13088.

Abstract
Pregnancy loss is a multidisciplinary problem which concerns researchers from the fields of medicine, epidemiology, psychology, and public health. The primary objective of the present study was to explain the potential role of neutrophil extracellular traps (NETs) in the process of spontaneous miscarriage. Enzyme-linked immunosorbent assay to assess the levels of biomarkers of NETs in the serum of examined women was conducted. Furthermore, levels of nitric oxide (NO) and late markers of its action were measured in serum samples. Analyses results demonstrated the existence of NETs in the placental tissue of women who miscarried as well as a simultaneous increase in the levels of myeloperoxidase and pentraxin 3. This clearly confirms the participation of NETs in the course of pregnancy loss. Women who have had a miscarriage but did not show the presence of NETs in their placenta exhibited the highest contents of NO, nitrotyrosine, and malondialdehyde suggesting a different pathway leading to pregnancy loss associated with disturbed oxidative-antioxidative processes. Although study results demonstrate new aspects associated with the formation of NETs they are not, however, sufficient to unambiguously determine the role of NETs in the course of miscarriage.

Increased Expression of Pentraxin 3 in Placental Tissues from Patients with Unexplained Recurrent Pregnancy Loss. Balkan J Med Genet 2019; 22:21-28.

Abstract
Pentraxin 3 (PTX3), a prototypical member of the long pentraxin subfamily, is a evolutionarily conserved multimeric pattern recognition receptor involved in the humoral component of the innate immune system. Pentraxin 3 is released when tissue is stressed or damaged, and interacts with many different ligands. Pentraxin 3 exerts a pivotal role both as a regulator and as an indicator of inflammatory response in the pathogenesis of many diseases such as sepsis, vasculitis and preeclampsia. Uncontrolled inflammatory response is considered a major cause of unexplained recurrent pregnancy loss (URPL). We determined the PTX3 messenger ribonucleic acid (mRNA) and protein expression levels in placentai tissues from 50 women with URPL, and made comparison with those in 50 age-matched control subjects. In quantitative real-time polymerase chain reaction (qRT-PCR) and immunohistochemistry analyses, PTX3 mRNA and protein levels, respectively, were significantly increased in URPL patients compared with their respective controls (p = 0.0001). Although no significant correlations were identified between PTX3 expression levels and clinical parameters such as maternal age, numbers of previous pregnancy losses, and gestational age at miscarriage, PTX3 mRNA expression was significantly higher in patients with no live births than in women with previous live births (p = 0.0001). Our study suggests that tissue-specific expression of PTX3 is associated with URPL. Further larger studies are required to determine whether PTX3 expression can be used as a biomarker to manage URPL in routine clinical practice.

Abstract
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.

Abstract
OBJECTIVE Many approaches try to identify the underlying molecular mechanisms to detect new potential biomarkers for successful artificial reproductive therapies. One factor has been described as a possible regulator of inflammation during implantation: Pentraxin 3 (PTX3), which seems to be essential for female fertility on one hand, but whose overexpression has been described in many obstetric complications based on abnormal placentation on the other hand. Therefore, we investigated if serum levels of PTX3 at the time of embryo transfer differ between women with an ongoing pregnancy compared to those without implantation. METHODS/DESIGN During in vitro fertilization cycles of 51 patients, PTX3 levels at the time of embryo transfer were compared between patients without implantation (n = 26) and those with ongoing pregnancy (n = 25) using an enzyme-linked immunosorbent assay. Statistical analysis was performed using the Kolmogorov-Smirnov test, Fisher's exact test and Student's t test RESULTS: No significant differences were found concerning possible confounders (patients age, smoking pattern, embryo quality, number of embryos transferred and prior IVF attempts). Patients without implantation presented with significantly higher serum levels of PTX3 at the time of embryo transfer compared to women who became pregnant (0.781 ± 0.074 ng/ml vs. 0.578 ± 0.055 ng/ml, p < 0.05). CONCLUSIONS PTX3 could present as a possible biomarker for ART success. The main limitation of this pilot study is its small sample size that needs validation with a larger study population.

Abstract
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 11 ng/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.

Abstract
Recurrent spontaneous abortion (RSA) occurs in 1–5% of parturients. The sustained therapy and research for RSA is expensive, which is a serious issue faced by both patients and doctors. The aim of the present study was to detect protein expression profiles in the serum of RSA patients and healthy controls, and to identify potential biomarkers for this disease. A 1,000-protein microarray consisting of a combination of Human L-507 and L-493 was used. The microarray data revealed that eight serum protein expression levels were significantly upregulated and 143 proteins were downregulated in RSA patients compared with the healthy controls. ELISA individually validated 5 of these 151 proteins in a larger cohort of patients and control samples, demonstrating a significant decrease in insulin-like growth factor-binding protein-related protein 1 (IFGBP-rp1)/IGFBP-7, Dickkopf-related protein 3 (Dkk3), receptor for advanced glycation end products (RAGE) and angiopoietin-2 levels in patients with RSA. Sensitivity and specificity analyses were calculated by a receiver operating characteristics curve, and were revealed to be 0.881, 0.823, 0.79 and 0.814, with diagnostic cut-off points of 95.44 ng/ml for IFGBP-rp1, 32.84 ng/ml for Dkk3, 147.27 ng/ml for RAGE and 441.40 ng/ml for angiopoietin-2. The present study indicated that these four proteins were downregulated in RSA samples and may be useful as biomarkers for the prediction and diagnosis of RSA. Subsequent studies in larger-scale cohorts are required to further validate the diagnostic value of these markers.

Abstract
OBJECTIVE To assess maternal serum amyloid A (SAA) levels among women with primary unexplained recurrent early pregnancy loss (REPL). METHODS A prospective study was conducted among women with missed spontaneous abortion in the first trimester at Ain Shams University Maternity Hospital, Cairo, Egypt, between January 21 and December 25, 2014. Women with at least two consecutive primary unexplained REPLs and no previous live births were enrolled. A control group was formed of women with no history of REPL who had at least one previous uneventful pregnancy with no adverse outcomes. Serum samples were collected to measure SAA levels. The main outcome was the association between SAA and primary unexplained REPL. RESULTS Each group contained 96 participants. Median SAA level was significantly higher among women with REPL (50.0 μg/mL, interquartile range 26.0-69.0) than among women in the control group (11.6 μg/mL, interquartile range 6.2-15.5; P<0.001). The SAA level was an independent indicator of primary unexplained REPL, after adjusting for maternal age and gestational age (odds ratio 1.12, 95% confidence interval 1.06-1.19; P<0.001). CONCLUSION Elevated SAA levels found among women with primary unexplained REPL could represent a novel biomarker for this complication of pregnancy.

Abstract
OBJECTIVE To study the association between Porphyromonas gingivalis (P. gingivalis) infection and recurrent miscarriage. METHODS This case control study included women with early pregnancy failure admitted for surgical evacuation of retained products of conception. Cases (group 1) included 50 women with unexplained recurrent early miscarriage whereas the control group (group 2) consisted of 50 women with no such history. The evacuated products of conception, subgingival plaques, cervicovaginal secretions and saliva of all participants were examined to detect P. gingivalis deoxyribonucleic acid (DNA) using a polymerase chain reaction. RESULTS The prevalence of P. gingivalis DNA in the chorionic villous tissue samples of group 1 was significantly higher than in group 2 (8 [16%] vs. 1 [2%], respectively; p = 0.036, odds ratio [OR]: 9.3, 95% confidence interval [CI]: 1.1-76.9). The prevalence of P. gingivalis DNA was significantly higher in cervicovaginal secretions of group 1 than in group 2 (9 [18%] vs. 1 [2%], respectively; p = 0.02, OR: 10.8, 95% CI: 1.3-88.5). On the contrary, P. gingivalis DNA could not be detected in subgingival plaques and saliva samples of either group. CONCLUSION The current study found an association between P. gingivalis infection of the female genital tract and the occurrence of recurrent miscarriage.

Abstract
BACKGROUND Histidine-rich glycoprotein (HRG) has previously been shown to have an impact on implantation and fertility. The aim of this study was to investigate if there is an association between the HRG A1042G single nucleotide polymorphism (SNP) and recurrent miscarriage. METHODS The study was designed as a case-control study and the women were included at University Hospitals in Sweden. 186 cases with recurrent miscarriage were compared with 380 pregnant controls with no history of miscarriage. Each woman was genotyped for the HRG A1042G SNP. RESULTS The results indicated that the frequency of heterozygous HRG A1042G carriers was higher among controls compared to cases (34.7% vs 26.3%; p<0.05). In a bivariate regression analysis, a negative association was found between recurrent miscarriage and heterozygous A/G carriers both in the entire study population (OR 0.67, 95% CI 0.45 - 0.99; p<0.05) as well as in a subgroup of women with primary recurrent miscarriage (OR 0.37, 95% CI 0.16 - 0.84; p<0.05). These results remained even after adjustment for known confounders such as age, BMI and thyroid disease (OR 0.36, 95% CI 0.15 - 0.84; p<0.05). CONCLUSIONS Women who are heterozygous carriers of the HRG A1042G SNP suffer from recurrent miscarriage more seldom than homozygous carriers. Thus, analysis of the HRG A1042G SNP might be of importance for individual counseling regarding miscarriage.

Abstract
OBJECTIVE To assess whether or not there is an association between the cytotoxin-associated gene A (CagA)-positive strain of Helicobacter (H.) pylori and unexplained recurrent early pregnancy loss (REPL). METHODS A case control study was conducted in a tertiary care maternity centre during a one-year period. Ninety-six women with first trimester unexplained REPL admitted for surgical or medical termination of pregnancy were included in the study group (group 1), along with 96 women who suffered a first trimester missed abortion but had no history of REPL and who were included in the control group (group 2). Sera from all these women were collected for detection of the CagA line of IgG type of H. pylori using an immunoblotting assay. The main outcome measure was the association between the CagA-positive strain of H. pylori and unexplained REPL. RESULTS A significantly greater proportion of women were seropositive for the CagA- H. pylori strain in group 1 than in group 2 (71 [74%] vs. 51 [53%], respectively; p = 0.003). CONCLUSION The CagA-positive strain of H. pylori seems to be significantly more prevalent among women with unexplained REPL when compared to women with a single missed abortion.
