BMC Pediatr 2024; 24:107. [PMID: 38347448 PMCID: PMC10860215 DOI: 10.1186/s12887-024-04556-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/05/2022] [Accepted: 01/11/2024] [Indexed: 02/15/2024] Open
Abstract
OBJECTIVE As the predominant complication in preterm infants, Bronchopulmonary Dysplasia (BPD) necessitates accurate identification of infants at risk and expedited therapeutic interventions for an improved prognosis. This study evaluates the potential of Monosaccharide Composite (MC) enriched with environmental information from circulating glycans as a diagnostic biomarker for early-onset BPD, and, concurrently, appraises BPD risk in premature neonates. MATERIALS AND METHODS The study incorporated 234 neonates of ≤32 weeks gestational age. Clinical data and serum samples, collected one week post-birth, were meticulously assessed. The quantification of serum-free monosaccharides and their degraded counterparts was accomplished via High-performance Liquid Chromatography (HPLC). Logistic regression analysis facilitated the construction of models for early BPD diagnosis. The diagnostic potential of various monosaccharides for BPD was determined using Receiver Operating Characteristic (ROC) curves, integrating clinical data for enhanced diagnostic precision, and evaluated by the Area Under the Curve (AUC). RESULTS Among the 234 neonates deemed eligible, BPD development was noted in 68 (29.06%), with 70.59% mild (48/68) and 29.41% moderate-severe (20/68) cases. Multivariate analysis delineated several significant risk factors for BPD, including gestational age, birth weight, duration of both invasive mechanical and non-invasive ventilation, Patent Ductus Arteriosus (PDA), pregnancy-induced hypertension, and concentrations of two free monosaccharides (Glc-F and Man-F) and five degraded monosaccharides (Fuc-D, GalN-D, Glc-D, and Man-D). Notably, the concentrations of Glc-D and Fuc-D in the moderate-to-severe BPD group were significantly diminished relative to the mild BPD group. A potent predictive capability for BPD development was exhibited by the conjunction of gestational age and Fuc-D, with an AUC of 0.96. CONCLUSION A predictive model harnessing the power of gestational age and Fuc-D demonstrates promising efficacy in foretelling BPD development with high sensitivity (95.0%) and specificity (94.81%), potentially enabling timely intervention and improved neonatal outcomes.

J Cell Biochem 2021; 122:1506-1516. [PMID: 34192359 DOI: 10.1002/jcb.30072] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/07/2021] [Revised: 05/02/2021] [Accepted: 06/09/2021] [Indexed: 12/23/2022]
Abstract
As a unique and common obstetric complication of pregnant women, pre-eclampsia (PE) has been the first leading cause of maternal and perinatal morbidity and mortality in the world. Mounting studies have demonstrated that an abnormality of long noncoding RNA (lncRNA) expression was related to the pathological process of PE. Here, we showed that lncRNA AFAP1-AS1 was markedly downregulated in pre-eclamptic placentas. We further investigated the mechanism underlying the regulatory role of AFAP1-AS1 in PE using human trophoblast cells. In vitro functional assays revealed that AFAP1-AS1 knockdown inhibited trophoblast proliferation, migration, and invasion. Moreover, AFAP1-AS1 interacts with EZH2 and inhibits DUSP5 expression through modulating H3K27m3 in the DUSP5 promoter of trophoblast cells, thus being involved in PE pathogenesis. Overall, these findings suggest that AFAP1-AS1 could potentially become a prognostic biomarker as well as a new therapeutic target for PE.

Abstract
OBJECTIVE This study aimed to investigate the mechanisms of advanced glycation end products (AGEs) on cell tight conjunction and placental vascular permeability in BeWo cells. STUDY DESIGN Monolayer permeability assay and transmission electron microscopy were employed to reveal the transformation of the placental vascular permeability and cell tight conjunction. Immunofluorescence, western blot and RT-qPCR were adopted to determine the protein and mRNA levels. Anti-RAGE and NF-kB inhibitor (PDTC) were used to inactivate the RAGE/NF-kB signaling pathway. RESULTS AGEs significantly decreased trans-epithelial electrical resistance (TEER), while increased paracellular permeability (P < 0.05). TEM showed that AGEs made cell junction loose. AGEs inhibited ZO-1 and Occludin expressions, while anti-RAGE or PDTC partially restored their levels. AGEs also significantly increased mRNA RAGE and NF-kB expressions in BeWo cells (P < 0.05), and their expressions were inhibited by anti-RAGEy or PDTC. CONCLUSION AGEs could reduce the expressions of ZO-1 and Occludin by activating RAGE/NF-kB signaling pathway, thus increasing placental vascular permeability.

Bronchopulmonary dysplasia in neonates born to mothers with preeclampsia: Impact of small for gestational age. PLoS One 2018; 13:e0204498. [PMID: 30248159 PMCID: PMC6152970 DOI: 10.1371/journal.pone.0204498] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/21/2018] [Accepted: 09/10/2018] [Indexed: 12/28/2022] Open
Abstract
Background and objectives Small for gestational age and preeclampsia have both been described as risk factors for bronchopulmonary dysplasia in preterm neonates, but their respective role in the occurrence of bronchopulmonary dysplasia is debated. We evaluated the relation between small for gestational age and bronchopulmonary dysplasia in neonates born to mothers with preeclampsia. We hypothesized that low birth weight is still associated with bronchopulmonary dysplasia in this homogeneous population. Methods Retrospective single-center cohort study including 141 neonates born between 24 and 30 weeks’ gestation to mothers with preeclampsia. The main outcome measure was moderate to severe bronchopulmonary dysplasia at 36 weeks’ postmenstrual age. Neonates born small for gestational age (birthweight < 10th percentile on the AUDIPOG curves) were compared to those with appropriate birthweight for gestational age by bivariable analyses and logistic regression models, estimating odds ratios (ORs) and 95% confidence intervals (CIs). Results Bronchopulmonary dysplasia rates were 61.5% (32/52) and 27.4% (20/73) for small for gestational age and appropriate birthweight for gestational age neonates (p < .001). On adjustment for gestational age and other confounding factors, the risk of moderate to severe bronchopulmonary dysplasia was greater for small for gestational age than appropriate birthweight for gestational age neonates (adjusted OR = 5.9, 95% CI [2.2–15.4]), as was the composite outcome death or moderate to severe bronchopulmonary dysplasia (adjusted OR = 4.7, 95% CI [1.9–11.3]). Conclusions Small for gestational age was associated with bronchopulmonary dysplasia in very preterm neonates born to mothers with preeclampsia. Registration number CNIL no. 1747084.

J Gynecol Obstet Hum Reprod 2017; 47:17-21. [PMID: 29102706 DOI: 10.1016/j.jogoh.2017.10.007] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/11/2016] [Revised: 10/22/2017] [Accepted: 10/25/2017] [Indexed: 10/18/2022]
Abstract
OBJECTIVES Despite its simple definition, preeclampsia can have variable and atypical clinical presentations, an unpredictable course, and potential adverse maternal and fetal outcomes. No single test currently predicts risk or prognosis adequately. Scientific advances suggest that an angiogenic imbalance is involved in its pathophysiology. The objective of this study was to investigate the use of sFlt-1, PlGF, and their ratio in predicting preeclampsia. MATERIALS AND METHODS In a single-center prospective observational study, we measured the angiogenic markers sFlt-1 and PlGF and calculated the sFlt-1/PlGF ratio in patients at risk of preeclampsia at 20 to 37 weeks of gestation. The main outcomes were the occurrence of preeclampsia and the interval before its onset. RESULTS Of the 67 at risk patients included, 8 (12%) developed preeclampsia. For a sFlt-1/PlGF ratio ≥85, the specificity was 93%. The ratio was significantly higher (ratio=104±30) in women with an onset time less than 5 weeks than in those with later preeclampsia (ratio=10±2), P<0.001. CONCLUSION In a high-risk population, angiogenic markers appear to be an interesting aid in predicting the onset of preeclampsia with high specificity and in estimating time to onset. However, due to small number of cases of PE, more studies are needed before recommendations to use these markers in daily practice.

Abstract
Preeclampsia (PE), a specific complication of pregnancy, is one of the most frequent causes of maternal and fetal morbidity and mortality in the world. Recently, PE risk calculation algorithms allowing early detection of PE in the first trimester of pregnancy have been described. The aim of early detection would be to rapidly introduce an effective preventive treatment. The aim of our work is to study the different preventive treatments through the literature. Aspirin has some efficiency and reduces the risk of PE from 10 to 24%. It is most effective when the dose exceeds 75mg and when introduced before 16 gestational age. Early introduction of aspirin mainly prevents severe and preterm PE. Low molecular weight heparin (LMWH) and vitamin D appear to be promising therapy for PE but further research is required. Calcium administered at 1g/day reduces the risk of PE especially to patients with low baseline calcium intake. A low dose of calcium could also reduce the risk of PE but this must be confirmed. Other preventive measures (antioxidants, nitric oxide, progesterone, rest, exercise) do not reduce the incidence of PE.

J Nutr 2016; 146:532-41. [PMID: 26865647 DOI: 10.3945/jn.115.221267] [Citation(s) in RCA: 31] [Impact Index Per Article: 3.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/30/2015] [Accepted: 01/04/2016] [Indexed: 01/09/2023] Open
Abstract
BACKGROUND Intrauterine growth restriction (IUGR) results from either maternal undernutrition or impaired placental blood flow, exposing offspring to increased perinatal mortality and a higher risk of metabolic syndrome and cardiovascular disease during adulthood. l-Citrulline is a precursor of l-arginine and nitric oxide (NO), which regulates placental blood flow. Moreover, l-citrulline stimulates protein synthesis in other models of undernutrition. OBJECTIVE The aim of the study was to determine whether l-citrulline supplementation would enhance fetal growth in a model of IUGR induced by maternal dietary protein restriction. METHODS Pregnant rats were fed either a control (20% protein) or a low-protein (LP; 4% protein) diet. LP dams were randomly allocated to drink tap water either as such or supplemented with l-citrulline (2 g · kg(-1) · d(-1)), an isonitrogenous amount of l-arginine, or nonessential l-amino acids (NEAAs). On day 21 of gestation, dams received a 2-h infusion of l-[1-(13)C]-valine until fetuses were extracted by cesarean delivery. Isotope enrichments were measured in free amino acids and fetal muscle, liver, and placenta protein by GC-mass spectrometry. RESULTS Fetal weight was ∼29% lower in the LP group (3.82 ± 0.06 g) than in the control group (5.41 ± 0.10 g) (P < 0.001). Regardless of supplementation, fetal weight remained below that of control fetuses. Yet, compared with the LP group, l-citrulline and l-arginine equally increased fetal weight to 4.15 ± 0.08 g (P < 0.05) and 4.13 ± 0.1 g (P < 0.05 compared with LP), respectively, whereas NEAA did not (4.05 ± 0.05 g; P = 0.07). Fetal muscle protein fractional synthesis rate was 35% lower in the LP fetuses (41% ± 11%/d) than in the control (61% ± 13%/d) fetuses (P < 0.001) and was normalized by l-citrulline (56% ± 4%/d; P < 0.05 compared with LP, NS compared with control) and not by other supplements. Urinary nitrite and nitrate excretion was lower in the LP group (6.4 ± 0.8 μmol/d) than in the control group (17.9 ± 1.1 μmol/d; P < 0.001) and increased in response to l-citrulline or l-arginine (12.1 ± 2.2 and 10.6 ± 0.9 μmol/d; P < 0.05), whereas they did not in the LP + NEAA group. CONCLUSION l-Citrulline increases fetal growth in a model of IUGR, and the effect may be mediated by enhanced fetal muscle protein synthesis and/or increased NO production.

Abstract
OBJECTIVES Placental growth factor (PlGF) is a pro-angiogenic factor mainly assessed in preeclampsia in which its blood concentration is decreased. The aim of this study was to dose the blood concentration of PlGF in women with fetal intra-uterine growth restriction (IUGR) without associated preeclampsia at the time of diagnosis. METHODS Case/control study: IUGR was defined by a fetal biometry with abnormal uterine and/or umbilical doppler (n=23). This group was compared to a control group of fetuses (n=25) matched for gestational age at blood sampling for the dosage of maternal seric PlGF. Women with preeclampsia were not included. RESULTS The plasma PlGF concentration was 11pg/mL (IQR [11-42,8]) in the IUGR group vs 287pg/mL [135-439] in the control group (P<0.001) and this difference was available after adjustment for gestational age at the time of blood sampling (P<0.001). PlGF sensitivity and specificity for discrimination were respectively 87% (CI 95% [66-97]) and 88% (CI 95% [69-97]). CONCLUSION Maternal serum PlGF concentrations were very low in IUGR group compared with those of the control group.

Abstract
OBJECTIVES Preeclampsia is one of the most frequent and most serious complications of pregnancy. Its occurrence is around 5% of the pregnancies. Its pathophysiology is complex and includes several hypotheses. Preeclampsia is inconsistently associated with intrauterine growth retardation (IUGR). The determinants that explain the variability of this association are unknown. The objective of our study was to identify in a population of French patients who had preeclampsia and/or HELLP syndrome, incidence and risk factors of IUGR to isolate specific characteristics of these women. PATIENTS AND METHODS We studied 578 pregnant women treated for preeclampsia or HELLP syndrome according to the presence or absence of IUGR (database compiled since 1996). Comparisons between the groups were done with Wilcoxon test (quantitative data) or Fisher's exact test (qualitative data). RESULTS We found that pre-eclampsia appeared earlier and was more severe in the group with IUGR. In addition foetal issues were more defavorable when IUGR was associated with preeclampsia. CONCLUSION Combination of IUGR and pre-eclampsia or HELLP syndrome is a criterion of severity for both the mother and the fetus. Our data do not allow distinguishing physiopathological mechanism to explain these differences.
