Abstract
Preeclampsia, a serious and potentially life-threatening medical complication occurring during pregnancy, is characterized by hypertension and often accompanied by proteinuria and multiorgan dysfunction. It is classified into two subtypes based on the timing of diagnosis: early-onset (EO-PE) and late-onset preeclampsia (LO-PE). Despite being less severe and exhibiting distinct pathophysiological characteristics, LO-PE is more prevalent than EO-PE, although both conditions have a significant impact on placental health. Previous research indicates that different pathophysiological events within the placenta may contribute to the development of preeclampsia across multiple pathways. In our experimental study, we investigated markers of oxidative stress, ferroptosis, and lipid peroxidation pathways in placental tissue samples obtained from women with LO-PE (n = 68) compared to healthy control pregnant women (HC, n = 43). Through a comprehensive analysis, we observed an upregulation of specific molecules associated with these pathways, including NADPH oxidase 1 (NOX-1), NADPH oxidase 2 (NOX-2), transferrin receptor protein 1 (TFRC), arachidonate 5-lipoxygenase (ALOX-5), acyl-CoA synthetase long-chain family member 4 (ACSL-4), glutathione peroxidase 4 (GPX4) and malondialdehyde (MDA) in women with LO-PE. Furthermore, increased ferric tissue deposition (Fe3+) was observed in placenta samples stained with Perls' Prussian blue. The assessment involved gene and protein expression analyses conducted through RT-qPCR experiments and immunohistochemistry assays. Our findings underscore the heightened activation of inflammatory pathways in LO-PE compared to HC, highlighting the pathological mechanisms underlying this pregnancy disorder.

Abstract
The renin-angiotensin-aldosterone system has an indispensable function in the uteroplacental circulation, placental growth, and blood pressure optimization. The angiotensin I converting enzyme (ACE) gene is a critical integrator for electrolyte balance, and water retention, along with inhibiting preeclampsia. The main goal of this pertaining study is to assess the contribution of ACE*(Ins/Del) variant with the susceptibility for preeclampsia with focus on the severity of the disease among gestational hypertensive women. This retrospective study included 225 participants [125 PE gestational women, and 100 normotensive healthy controls] matching with age, and geographical region. PE women classified into 82 early-onset PE women, accompanied with 43 late-onset PE women. Additionally, PE women categorized into 59 mild PE women, together with 66 severe PE women. The genotyping and characterization of ACE*(Ins/Del) variant were applied using the PCR technique. Our findings indicated higher frequency of the ACE*(Del/Del) genotype and ACE*(D allele) with elevated risk of preeclampsia compared to normotensive controls under recessive (OR = 2.09, and p-value = 0.007), and allelic (OR = 1.75, and p-value = 0.012) models. In addition, testing logistic regression revealed that the levels of endothelin-1 and malondialdehyde exposed significant difference for the ACE*(Del/Del) genotype among early-onset and late-onset PE women (p-value = 0.024, and 0.23, respectively). Furthermore, carriers of the ACE*(Del/Del) genotype observed statistically significant with lower sodium concentrations among severe PE women (p-value = 0.034). The ACE*(Del/Del) genotype and ACE*(D allele) were associated with increased risk preeclampsia among gestational women. Furthermore, early-onset PE and late-onset PE were correlated with endothelin-1 and malondialdehyde concentrations among Egyptian women.

Endothelial cell vasodilator dysfunction mediates progressive pregnancy-induced hypertension in endothelial cell tetrahydrobiopterin deficient mice. Vascul Pharmacol 2023; 150:107168. [PMID: 36966985 DOI: 10.1016/j.vph.2023.107168] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/12/2022] [Revised: 03/05/2023] [Accepted: 03/19/2023] [Indexed: 04/10/2023]
Abstract
BACKGROUND AND PURPOSE Pregnancy-associated vascular remodelling is essential for both maternal and fetal health. We have previously shown that maternal endothelial cell tetrahydrobiopterin (BH4) deficiency causes poor pregnancy outcomes. Here, we investigated the role and mechanisms of endothelial cell-mediated vasorelaxation function in these outcomes. EXPERIMENTAL APPROACH The vascular reactivity of mouse aortas and uterine arteries from non-pregnant and pregnant endothelial cell-specific BH4 deficient mice (Gch1fl/flTie2cre mice) was assessed by wire myography. Systolic blood pressure was assessed by tail cuff plethysmography. KEY RESULTS In late pregnancy, systolic blood pressure was significantly higher (∼24 mmHg) in Gch1fl/flTie2cre mice compared with wild-type littermates. This was accompanied by enhanced vasoconstriction and reduced endothelial-dependent vasodilation in both aorta and uterine arteries from pregnant Gch1fl/flTie2cre mice. In uterine arteries loss of eNOS-derived vasodilators was partially compensated by upregulation of intermediate and large-conductance Ca2+-activated K+ channels. In rescue experiments, oral BH4 supplementation alone did not rescue vascular dysfunction and pregnancy-induced hypertension in Gch1fl/flTie2cre mice. However, combination with the fully reduced folate, 5-methyltetrahydrofolate (5-MTHF), restored endothelial cell vasodilator function and blood pressure. CONCLUSIONS AND IMPLICATIONS We identify a critical requirement for maternal endothelial cell Gch1/BH4 biosynthesis in endothelial cell vasodilator function in pregnancy. Targeting vascular Gch1 and BH4 biosynthesis with reduced folates may provide a novel therapeutic target for the prevention and treatment of pregnancy-related hypertension.

Abstract
OBJECTIVES An imbalanced redox homeostasis resulting in oxidative stress is present in preeclampsia. Peroxiredoxin-1 (PRDX1) and thioredoxin-1 (TRX1) regulatory enzymes are also contributing to the redox homeostasis, but were not investigated so far in preeclampsia. Thus, we have aimed to characterize PRDX1, TRX1 and oxidative stress biomarkers in blood samples of pregnant women with preeclampsia. STUDY DESIGN Twelve patients with preeclampsia (PE) were enrolled into the study. Seven third trimester healthy pregnant women (HP) were accepted as control group. MAIN OUTCOME MEASURES Peripheral venous blood samples of healthy and preeclamptic pregnant women were analyzed. Plasma level of advanced oxidation protein products (AOPP) was determined by spectrophotometry. The exofacial PRDX1 and TRX1 expression of lymphocytes and monocytes was detected by flow cytometry. RESULTS The plasma AOPP level was significantly higher in preeclampsia compared to the healthy pregnant group. Significantly higher percentage of PRDX1 and TRX1 expressing lymphocytes and monocytes were detected in the blood samples of preeclamptic women compared to healthy pregnant controls. The ratio of circulating PRDX1 and TRX1 expressing lymphocytes and monocytes showed a significant inverse correlation with the birth weight of newborns. CONCLUSIONS We have revealed that the level of advanced oxidation protein products is increased and the exofacial peroxiredoxin-1 and thioredoxin-1 system in lymphocytes and monocytes is upregulated in preeclampsia. In addition, the ratio of peroxiredoxin-1 and thioredoxin-1 positive circulating lymphocytes and monocytes correlates inversely with the neonatal birth weight, which finding indicates that pregnancies complicated by intrauterine growth restriction are accompanied by a higher level of oxidative stress.

Abstract
Background This study aimed to investigate the serum levels of mucoprotein 3 in hypertensive diseases of pregnancy. Methods In total, 60 consecutive women with gestational hypertensive diseases (gestational hypertension (n = 20), severe preeclampsia (n = 20), HELLP syndrome (n = 20)) and 20 pregnant women without any gestational hypertensive diseases were included for this prospective controlled study. Serum MUC3 protein levels were measured with commercially available ELISA kits. Results Serum MUC3 protein level was the lowest in normal pregnant women (0.1047 ± 0.0295 ng/ml); while the severity of the disease increases, it significantly increased in severe preeclampsia (0.2700 ± 0.0199 ng/mL) and HELLP syndrome group (0.3494 ± 0.0455 ng/mL), but less in the gestational hypertension (0.2172 ± 0.0354 ng/mL) group. Mean serum MUC3 protein level differences were found the least in gestational hypertension (0.1125 ± 0.0107, p < 0.001), the most in HELLP syndrome (-0.2546 ± 0.0107, p < 0.001) compared with the pregnant control group. Conclusion The increase in serum MUC3 protein concentration in these women supported the argument that serum MUC3 protein may be used as a marker indicating the severity of the gestational hypertensive diseases.

Abstract
Abstract
Preeclampsia (PE) is a major complication of pregnancy with both mother and fetal adverse outcomes. Pregnancy is a state of increased oxidative stress that has been reported to be exacerbated when complicated with preeclampsia. However, conflicting data are available in literature regarding the systemic oxidative stress in PE pregnancies. The present pilot study was purported to assess systemic oxidative stress in preeclamptic vs healthy pregnancies. To this aim plasma derived compounds of reactive oxygen metabolites (d-ROMs) and the biological antioxidant potential (BAP) were determined in mild and severe preeclamptic pregnancies using the Diacron equipment. Both healthy and preeclamptic pregnancies showed high levels of systemic oxidative stress. Paradoxically, significantly higher values of d-ROMs were found in healthy pregnancies as compared to the PE ones. At variance, in preeclamptic pregnancies, a major increase in the plasma antioxidant capacity occurred. In this pilot study, we report an increase in the systemic antioxidant capacity in preeclamptic pregnancies.

Abstract
OBJECTIVE This research aimed to explore the predictive value of levels of vitamin A and E in pre-eclampsia and postpartum kidney injury. METHODS A total of 106 pregnant women with severe pre-eclampsia diagnosed in our hospital from May 2015 to December 2018 were selected as the research subjects. There from, 75 pregnant women with severe pre-eclampsia were enrolled into the severe PE group (SPE) and 31 with acute kidney injury were divided into the severe PE and AKI group (SPE and AKI). Serum vitamin A and E content was determined by high-performance liquid chromatography (HPLC), and the correlation between vitamins A and E and disease was analyzed. The expression levels of kidney injury markers in both groups were detected, and the correlation between markers and vitamin A and E levels was analyzed. RESULTS The expression level of vitamins A and E decreased in the pre-eclampsia and postpartum kidney injury, and it was negatively correlated with disease severity. The expression of the two decreased further in the severe pre-eclampsia patients with kidney injury. In addition, the expression of kidney injury markers in the severe pre-eclampsia patients with postpartum kidney injury was higher than that in severe pre-eclampsia patients, and it was negatively correlated with vitamin A and E levels. CONCLUSION Vitamins A and E are expressed in low levels in pre-eclampsia and postpartum kidney injury, and the latter has a higher sensitivity and specificity than the former. It is negatively correlated with kidney injury markers KIM-1, NGAL, UA and Scr, which can be used as a physical and chemical indexes for clinical prediction.

Oxidative Stress Markers Differ in Two Placental Dysfunction Pathologies: Pregnancy-Induced Hypertension and Intrauterine Growth Restriction. OXIDATIVE MEDICINE AND CELLULAR LONGEVITY 2020; 2020:1323891. [PMID: 32685085 PMCID: PMC7346256 DOI: 10.1155/2020/1323891] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/24/2020] [Revised: 05/27/2020] [Accepted: 06/19/2020] [Indexed: 01/07/2023]
Abstract
Aim Pregnancy-induced hypertension (PIH) and intrauterine growth restriction (IUGR) are both multisystemic disorders of pregnancy that cause perinatal morbidity and mortality. Recently, researchers focused on the role of oxidative stress (OS) as a pathophysiological mechanism in the development of these pathologies. The aim of this study was to compare OS in placental-related pathologies (PIH and IUGR) and uncomplicated pregnancies. We also investigated which salivary OS markers reflect systemic oxidative status and which only reflect the state of the oral cavity. Material and Methods. A total of 104 pregnant women (n = 104; 27 with PIH, 30 with IUGR, and 47 controls) were evaluated. Malondialdehyde (MDA), total antioxidant capacity (ORAC), aldehyde dehydrogenase (ALDH), and activity of glutathione peroxidase (GPx) and glutathione transferase (GST) in plasma/whole blood and/or saliva were analysed. Dietary nutrient intake was calculated using a Semiquantitative Food Frequency Questionnaire (SFFQ). Oral health was assessed to eliminate patients with bleeding, severe periodontitis, and other dental pathologies. Results In the IUGR group, increased concentration of ORAC was observed both in saliva and plasma. Also, lower plasma levels of MDA in IUGR compared to the control group was detected. No sign of oxidative stress was confirmed in the PIH group. The examined groups did not differ regarding diet and markers of inflammation. ORAC in saliva was correlated with its level in plasma. No such correlations for MDA were observed. In the IUGR group, there were no differences in OS markers in plasma, but there was a lower ALDH level in the blood compared to the control group. It confirms OS occurrence in IUGR. In IUGR, a higher activity of salivary ALDH was probably due to worse oral health. Conclusion Oxidative stress differs between IUGR and PIH groups: the presence of oxidative stress was confirmed only in the IUGR group. Salivary ORAC can be used to estimate ORAC in plasma. The activity of salivary ALDH reflects the state of the oral cavity.

Abstract
Background: Limited studies have been conducted to evaluate the utility of indices for the prediction of the adverse neonatal outcomes in hypertensive disorders of pregnancy (HDP).Method: A total of 174 pregnant women with HDP (gestational hypertension, late onset preeclampsia, and early onset preeclampsia) and 49 controls were sampled during the third trimester. Preterm birth, low birth weight, fetal, and infant mortality and low Apgar scores were assessed.Results: Multivariate analysis confirmed systolic blood pressure (SBP), time of onset of hypertension (TOH), and total antioxidant status (TAS) as predictors of preterm births; TOH and diastolic blood pressure (DBP) to be predictors of low birth weight babies; TOH and asymmetric dimethyl arginine (ADMA) as predictors of fetal mortality and babies with low Apgar at 5 min. We found TOH as the single best predictor for adverse neonatal outcomes.Conclusion: This study identified TOH as an important predictor of most of the adverse neonatal outcomes.

Effect of maternal omega-3 fatty acids and vitamin E supplementation on placental apoptotic markers in rat model of early and late onset preeclampsia. Life Sci 2019; 239:117038. [PMID: 31730868 DOI: 10.1016/j.lfs.2019.117038] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/12/2019] [Revised: 10/23/2019] [Accepted: 10/31/2019] [Indexed: 12/19/2022]
Abstract
AIM Disturbed placentation results in pregnancy complications like preeclampsia. Placental development is influenced by apoptosis during trophoblast differentiation and proliferation. Increased oxidative stress upregulates placental apoptosis. We have earlier reported increased oxidative stress, lower omega-3 fatty acids and vitamin E levels in women with preeclampsia. Current study examines effect of maternal omega-3 fatty acids and vitamin E supplementation on apoptotic markers across gestation in a rat model of preeclampsia. MAIN METHODS Pregnant Wistar rats were randomly assigned to control; early onset preeclampsia (EOP); late onset preeclampsia (LOP); early onset preeclampsia + omega-3 fatty acid + vitamin E supplementation (EOP + O + E) and late onset preeclampsia + omega-3 fatty acid + vitamin E supplementation (LOP + O + E) groups. Animals (Control, EOP, EOP + O + E) were sacrificed at d14 and d20 of gestation while animals (LOP, LOP + O + E) were sacrificed at d20 to collect blood and placentae. Protein and mRNA levels of apoptotic markers were analyzed by ELISA and RT-PCR respectively. KEY FINDINGS Protein levels of proapoptotic markers like Bcl-2 associated X-protein (BAX) (p < 0.05), caspase-8 and 3 (p < 0.01 for both) and malondialdehyde (p < 0.01) were higher only in the EOP group as compared to control. However, the antiapoptotic marker, B cell lymphoma 2 (Bcl-2) protein levels were lower in both the subtypes of preeclampsia (p < 0.01 for both). SIGNIFICANCE Our findings suggest that supplementation was beneficial in reducing the caspase-8 and 3 in early onset preeclampsia but did not normalize BAX and Bcl-2 levels. This has implications for reducing placental apoptosis in preeclampsia.

Aldehyde dehydrogenase isoforms and inflammatory cell populations are differentially expressed in term human placentas affected by intrauterine growth restriction. Placenta 2019; 81:9-17. [PMID: 31138432 PMCID: PMC6719708 DOI: 10.1016/j.placenta.2019.03.015] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/25/2018] [Revised: 03/21/2019] [Accepted: 03/28/2019] [Indexed: 11/18/2022]
Abstract
OBJECTIVE Intrauterine growth restriction (IUGR) is a complication of pregnancy that has both short- and long-term sequelae for affected mothers and offspring. The pathophysiology of disease stems from poor nutrient and oxygen provision to the fetus, resulting in increased oxidative stress within the placenta. As the milieu within the local microenvironment alters macrophage differentiation, we hypothesized that macrophage plasticity may be altered in placentas associated with IUGR, and that macrophages would show hallmarks of lipid peroxidation including altered aldehyde metabolism. METHODS In human placentas taken from normal pregnancies resulting in appropriate-for-gestational-age (AGA) newborns and placentas associated with IUGR, placental macrophages were evaluated by immunohistochemistry and shown in IUGR to resemble pro-inflammatory activated M1-type macrophages. To link oxidative stress to macrophages, the expression of aldehyde dehydrogenase (ALDHs) isozymes ALDH1, ALDH2, and ALDH3 was assessed. RESULTS All three isozymes displayed preferential staining for distinct cellular populations within the term human placenta. ALDH1 and ALDH2 were strongly expressed in placental Hofbauer and decidual stromal cells. ALDH3, in contrast, was present in extravillous trophoblasts. Comparing AGA and IUGR-associated placentas, ALDH1 and ALDH2 trended to have greater expression in macrophage populations but lower expression in decidual cell populations in IUGR-associated placentas. ALDH3 had higher expression in IUGR-associated placentas but localized specifically to extravillous trophoblast populations. CONCLUSION Therefore, we speculate that specific ALDH isozymes have cell-specific functions related to differentiation, inflammation, or oxidative stress responses that are altered in IUGR-associated term human placentas. This family of isozymes may be a novel method to identify human placentas affected by placental insufficiency/IUGR.

Abstract
Abstract
Background
Specific metabolic changes during physiological pregnancy are characterized by hyperlipidemia and increased oxidative stress. However, these specific changes raise the question of their pro-atherogenic potential during pregnancy and their influence on the risk of developing cardiovascular disease (CVD) in women later in life, as well as complications during pregnancy. The aim of this study was to investigate the changes in lipid indexes and parameters of lipid peroxidation in non-complicated pregnancy in order to estimate their course of change and potential relationship during non-complicated pregnancy.
Methods
The study included 43 healthy pregnant women and 38 non-pregnant healthy women, in appropriate ages, as the control group. Lipid parameters and oxidative stress parameters were monitored in a longitudinal study in the first, second and third trimesters, and before delivery during non-complicated pregnancy.
Results
Results have shown that lipid indexes rise during pregnancy. The values were significantly increased when compared to the first trimester in all lipid indices and in comparison with the control group. Thyobarbituric acid reactive substances (TBARS) and lipid hydroperoxides (LOOH) were not changed significantly during physiological pregnancy, but LOOH showed a significantly higher value in the first trimester compared with the control group. Prooxidative-antioxidative balance (PAB) significantly increases as pregnancy progresses.
Conclusions
We observed the changes in lipids, lipid indexes and parameters that indicate oxidative modification of lipids in physiological pregnancy that may lead to an atherogenic, prooxidant state.

Abstract
Background Deficiencies of enzymes in the folate cycle may lead to the generation of homocysteine, a toxic metabolic intermediate with pro-oxidant effect and ability to induce oxidant stress and lipid peroxidation as part of the pathophysiological process in gestational hypertension (GH) and pre-eclampsia (PE). Aim The aim of this study is to assess the reliability of plasma homocysteine (hcy) 5, 10 methylenetetrahydrofolate reductase (MTHFR) enzyme and oxidative stress parameters as indicators of aetio-pathogenesis and severity of gestational hypertension and pre-eclampsia. Subjects and Methods This was a comparative cross-sectional study conducted over 6 months. Two hundred pregnant women were recruited from two sites. They were divided into gestation hypertension (n = 40), pre-eclampsia (n = 60) and control groups (n = 100). Parameters evaluated for statistical analysis were MTHFR enzyme level, plasma homocysteine and malondialdehyde (MDA) levels, with glutathione (GSH), superoxide dismutase (SOD) and catalase (CAT) activities. Results Mean plasma hcy level and MDA were significantly higher in pre-eclampsia and gestational hypertension when compared to control group (p < 0.05). However, MTHFR enzyme level, GSH, SOD and CAT were significantly higher in normotensive females when compared to PE and GH subgroups (p < 0.05). Pre-eclampsia was significantly associated with an increased risk of lipid peroxidation (OR = 4.923; p = 0.007). Conclusion Pre-eclampsia and gestational hypertension are associated with marked homocysteine metabolic derangement and increased lipid peroxidation induced by oxidative stress and reduced MTHFR enzyme activity which may be the significant risk factors in the aetio-pathogenesis of GH and PE.

Abstract
OBJECTIVE This study was done to determine whether Tualang honey could prevent the altered nociceptive behaviour, with its associated changes of oxidative stress markers and morphology of the spinal cord, among the offspring of prenatally stressed rats. METHODS Pregnant rats were divided into three groups: control, stress, and stress treated with Tualang honey. The stress and stress treated with Tualang honey groups were subjected to restraint stress from day 11 of pregnancy until delivery. Ten week old male offspring (n = 9 from each group) were given formalin injection and their nociceptive behaviours were recorded. After 2 h, the rats were sacrificed, and their spinal cords were removed to assess oxidative stress activity and morphology. Nociceptive behaviour was analysed using repeated measures analysis of variance (ANOVA), while the levels of oxidative stress parameters and number of Nissl-stained neurons were analysed using a one-way ANOVA. RESULTS This study demonstrated that prenatal stress was associated with increased nociceptive behaviour, changes in the oxidative stress parameters and morphology of the spinal cord of offspring exposed to prenatal stress; administration of Tualang honey reduced the alteration of these parameters. CONCLUSION This study provides a preliminary understanding of the beneficial effects of Tualang honey against the changes in oxidative stress and neuronal damage in the spinal cord of the offspring of prenatally stressed rats.

Abstract
BACKGROUND The placenta is a multifunctional organ that can suffer with imbalances between pro- and antioxidant molecules, contributing for inflammatory imbalance. The inflammation generated by oxidative stress may induce inflammasome activation, an essential complex for pro-inflammatory cytokine production. OBJECTIVE The aim of this study was to evaluate whether hydrogen peroxide (H2O2) mediated oxidative stress induces inflammasome activation on placental explants. STUDY DESIGN Tissue cultures of placental explants obtained from normotensive pregnant women were performed in different concentrations of H2O2. Gene expressions of NLRP3, caspase-1, IL-1β, TNF-α and IL-10 were evaluated by qPCR. Superoxide dismutase (SOD), catalase, Heat shock protein 70 (Hsp70), Caspase-1, TNF-α, IL-1β, IL-10 and human Chorionic Gonadotropin (hCG) were determined by ELISA. RESULTS Concentrations of catalase, Hsp70, hCG and SOD were higher in cultures with 100 and 1000 µM H2O2 compared to controls. Gene and protein expressions of TNF-α and IL-1β were elevated in cultures with 1000 μM H2O2 compared to controls. This concentration led to inflammasome activation, by increasing gene expressions of NLRP3, caspase-1 and IL-1β. In contrast, gene and protein expressions of IL-10 were reduced at 100 and 1000 μM H2O2. Protein expression of caspase-1 was higher in cultures of 100 μM H2O2 compared to controls. Treatment with Glybenclamide at 200 μM was used to prevent NLRP3 inflammasome activation. This concentration reduced protein expression of caspase-1 compared to culture with only H2O2 and control cultures. CONCLUSIONS Our results confirm that H2O2 induces oxidative stress on placental explants and demonstrate that cell responses to this stress involve inflammasome activation.

Abstract
Pre-eclampsia (PE) is a pregnancy disorder that is characterised by severe hypertension and increased risks of foetal and maternal mortality. The aetiology of PE not completely understood; however, maternal nutrition and oxidative stress play important roles in the development of hypertension. The treatment options for PE are currently limited to anti-hypertensive drugs. Punicalagin, a polyphenol present in pomegranate juice, has a range of bioactive properties. The effects of supplementation with punicalagin on angiogenesis and oxidative stress in pregnant rats with induced hypertension were investigated. The pregnant rats were randomly divided into five experimental groups (n=12 per group). Hypertension was induced using an oral dose of NG-nitro-L-arginine methyl ester (L-NAME, 50 mg/kg/day) on days 14-19 of pregnancy. Punicalagin (25, 50 or 100 mg/kg) was given orally on days 14-21 of pregnancy. Punicalagin treatment at the tested doses significantly reduced diastolic, systolic, and mean arterial blood pressure in L-NAME treated rats from day 14. Punicalagin also restored angiogenic balance by increasing the expression of vascular endothelial growth factor and downregulating vascular endothelial growth factor receptor-1/fms-like tyrosine kinase-1. Punicalagin, significantly increased the placental nitric oxide levels as compared to PE group. The increased levels of oxidative stress in rats with PE were markedly decreased by treatment with punicalagin. Punicalagin at the tested doses markedly (p<0.05) enhanced the placental antioxidant capacity in L-NAME-treated rats. The raised catalase activity observed following L-NAME induction was significantly (p<0.05) and restored to normal activity levels in punicalagin treatment. Further, 100 mg dose of punicalagin exhibited higher protective effects as compared to lower doses of 25 and 50 mg. This study shows that supplementation with punicalagin decreased blood pressure and oxidative stress and restored angiogenic balance in pregnant rats with induced PE.

Abstract
Introduction Hypertension in pregnancy is one of the potential causes of maternal and fetal morbidity and mortality. It complicates 7-10% of pregnancies. As of today, prediction of pregnancy hypertension is not possible. Aim and Objectives Evaluation of pregnancy associated plasma protein-A (PAPP-A), free β-human chorionic gonadotropin, tumor necrosis factor-α (TNF-α) and interferon gamma (INF-γ) in establishing a biomarker or combination of biomarkers for the early identification of pregnancy hypertension. Methodology This prospective study was carried out in two phases. Phase I was a cohort study in which 2000 pregnant women were enrolled in their first trimester (11 + 0 to 13 + 6 weeks of gestation) and followed till delivery. Women who developed hypertension were compared with normotensive cohort (women who remained normotensive till term). Phase II was a case-control study. The women who were diagnosed with hypertension in phase I were cases and their controls were matched for gestational age and sample storage time from normotensive cohort population. Two additional proinflammatory markers TNF-α and INF-γ were evaluated in this case-control population. Results Out of 2000 women, 199 women developed hypertension and 1454 women remained normotensive throughout their pregnancy. Among 199 hypertensive women, 151 (9.13%) cases had gestational hypertension, 45 (2.72%) had preeclampsia (PE) and 3 (0.18%) had eclampsia (E). First trimester mean arterial pressure (MAP) (p < 0.001) and body mass index (BMI) (p < 0.001) were found significantly higher in hypertensive women when compared with normotensive women. Maternal serum levels of PAPP-A (p < 0.001) were significantly low in hypertensive women as compared to normotensive women, while free β-hCG (p = 0.59) was high, but the difference was not statistically significant. TNF-α (p < 0.001) and INF-γ (p = 0.014) both were high in hypertensive women. When all biomarkers were combined we found the positive predictive value (PPV) of 51.6% an negative predictive value (NPV) of 71.4%. Conclusion Increased levels of proinflammatory cytokines suggest the role of underlying inflammation in pathogenesis of pregnancy hypertension, and low PAPP-A may be attributed to impaired implantation. Combining biomarkers may improve the prediction of pregnancy hypertension in the early stages of gestation. NPV of 71.4% depicts that if woman has all biomarkers in normal ranges during first trimester, she will have 71.4% chances of remaining normotensive during pregnancy.

Abstract
INTRODUCTION There is a balance between the oxidative and the anti-oxidative forces in human body. Some studies document decreased level of anti-oxidant in pre-eclampsia while other studies showed normal level of anti-oxidant in pre-eclampsia and the evidence is equivocal. AIM The aim of the present study was to assess enzymatic anti-oxidant activities in pre-eclamptic women and compare it with normotensive pregnant women with period of gestation between 28 to 36 weeks. MATERIALS AND METHODS A community-based cross-sectional survey was conducted (from November 2012-December 2013) at the Ballabgarh Health and Demographic Surveillance System (HDSS) site which was managed by Centre for Community Medicine, All India Institute of Medical Sciences, New Delhi, India. All registered pregnant women with period of gestation between 28 weeks - 36 weeks were eligible for inclusion in the study. All eligible pregnant women were contacted through home visit. A total of 217 pregnant women were enrolled out of which 209 blood samples were collected from pregnant women. About three ml of blood from antecubital vein was drawn without use of tourniquet, under aseptic conditions. It was later analysed for the serum anti-oxidative measures {Malanoaldehyde, Vitamin C, Ferric Reducing Ability of Plasma (FRAP) levels}. Data were entered on Epi-Info version 3.5.4. Data management and analysis was carried out in Stata 11. The means were compared using t-test and p-value stated. Categorical data was analysed using chi-square test. Logistic regression was used and adjusted p-value was stated. RESULTS A total of 217 pregnant women were eligible for the study and all were enrolled. Out of the 217 blood samples collected, eight samples accidently got destroyed. A total of 28 out of remaining 209 pregnant women (13.4%) had pre-eclampsia. Mean age (SD) was 22.4 (2.3) years, mean height (SD) was 156.6 (6.9) cm, mean weight (SD) was 65.1 (9.7) kg in pre-eclampsia group. In pre-eclampsia group mean serum levels of malanoaldehyde, vitamin C and FRAP was 4.2 (0.26) ng/dl, 0.83 (0.11) mg/dl, 678.0 (35.6) μmol/L. It was 4.5 (0.09) ng/dl,0.88 (0.03) mg/dl, 599.3 (13.3) μmol/L in normotensive pregnant women group respectively. The difference was statistically significant for FRAP levels only. CONCLUSION Serum anti-oxidant levels are not raised among women with pre-eclampsia.

Abstract
AIM Deficiency of vitamin D is correlated with pre-eclampsia (PE), a hypertensive disorder of pregnancy, and is characterized by angiogenic imbalance and inflammation. The aim of this study was to investigate whether vitamin D supplementation can restore the angiogenic balance and ameliorate inflammation in a rat model of PE. METHODS PE was induced using l-nitroarginine methylester. Normal pregnant and PE-induced rats were supplemented with vitamin D on gestation days 14-19. RESULTS Blood pressure was significantly increased in PE-induced rats compared with normal pregnant rats (P < 0.05), and vitamin D supplementation ameliorated this difference. In addition, rats from the PE group had lower vascular endothelial growth factor (VEGF; P < 0.01), and higher plasma-soluble FMS-like tyrosine kinase-1 (sFlt-1) and tumor necrosis factor-α (TNF-α; P < 0.01 for both) compared with the normal pregnant group. The vitamin D treatment group had significantly increased VEGF, and reduced sFlt-1 and TNF-α compared with the untreated PE group. Moreover, vitamin D supplementation was able to reduce the oxidative stress by lowering the plasma oxidative stress marker malondialdehyde. CONCLUSION Vitamin D supplementation plays an important role in restoring angiogenic balance and reducing inflammation in pregnancy-induced hypertension.

Abstract
OBJECTIVE Increased extent of lipid peroxidation and decreased antioxidant defense has been postulated as a major contributor to the development of preeclampsia. The present study was conducted to determine the serum level of malondialdehyde (MDA) and vitamin C in these patients. METHODS This research was conducted as a case-control study to assess the extent of lipid peroxidation and antioxidant status in 150 preeclampsia patients and 174 healthy pregnant women. Lipid peroxidation was assessed by measuring serum MDA level, and antioxidant defense was evaluated for serum vitamin C by UV spectrophotometric method. Independent sample t test and Pearson's correlation test were used for the statistical analysis with statistical software package SPSS, version 16.0 (SPSS, Inc., Chicago, IL). RESULTS Our study found significantly higher level of MDA (p < 0.05) and significantly lower level of vitamin C (p < 0.05) in preeclampsia patients in comparison to the control subjects. Pearson's correlation analysis revealed that there was negative correlation between the serum level of MDA and vitamin C for both patient (r = -0.057, p = 0.669) and control groups (r = -0.128, p = 0.487). Analysis of socio-economic data revealed that preeclampsia was more prevalent among the rural pregnant than the urban pregnant women (OR 1.44, 95% CI 0.665-3.14, p = 0.352). It was also observed that primigravida pregnant were at higher risk for the development of preeclampsia than the multigravida pregnant women (OR 1.87, 95% CI 0.868-4.04, p = 0.108). CONCLUSIONS Elevated serum MDA and depleted serum vitamin C may be associated with the development of preeclampsia.

Evaluation of Glutathione Peroxidase 4 role in Preeclampsia. Sci Rep 2016; 6:33300. [PMID: 27641822 PMCID: PMC5027559 DOI: 10.1038/srep33300] [Citation(s) in RCA: 15] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/27/2016] [Accepted: 08/24/2016] [Indexed: 12/31/2022] Open
Abstract
Preeclampsia (PE) is a pregnancy-specific syndrome that may be lifethreatening to pregnancies and fetus. Glutathione Peroxidase 4 (GPx4) is a powerful antioxidant enzyme that can provide protection from oxidative stress damage which plays a pivotal role in the pathology of PE. Therefore, this study aims to investigate the association between Gpx4 polymorphisms and the susceptibility to PE in Chinese Han women. TaqMan allelic discrimination real-time PCR was used to perform the genotyping of rs713041 and rs4807542 in 1008 PE patients and 1386 normotensive pregnancies. Obviously statistical difference of genotypic and allelic frequencies were found of rs713041 in GPx4 between PE patients and controls and the C allele has the higher risk for pathogenesis of PE (χ2 = 12.292, P = 0.002 by genotype; χ2 = 11.035, P = 0.001, OR = 1.216, 95% CI 1.084–1.365 by allele). Additionally, when subdividing these samples into CC + CT and TT groups, we found a significant difference between the two groups (χ2 = 11.241, P = 0.001, OR = 1.417, 95% CI 1.155–1.738). Furthermore, the genotype of rs713041 was found to be associated with the mild, severe and early-onset PE. Our results suggest that rs713041 in GPx4 may play a key role in the pathogenesis of PE.

Abstract
Objectives Our earlier studies have highlighted that an altered one carbon metabolism (vitamin B12, folic acid, and docosahexaenoic acid) is associated with preeclampsia. Preeclampsia is also known to be associated with oxidative stress and inflammation. The current study examines whether maternal folic acid, vitamin B12 and omega-3 fatty acid supplementation given either individually or in combination can ameliorate the oxidative stress markers in a rat model of pregnancy induced hypertension (PIH). Materials and Methods Pregnant Wistar rats were assigned to control and five treatment groups: PIH; PIH + vitamin B12; PIH + folic acid; PIH + Omega-3 fatty acids and PIH + combined micronutrient supplementation (vitamin B12 + folic acid + omega-3 fatty acids). L-Nitroarginine methylester (L-NAME; 50 mg/kg body weight/day) was used to induce hypertension during pregnancy. Blood Pressure (BP) was recorded during pregnancy and dams were dissected at d20 of gestation. Results Animals from the PIH group demonstrated higher (p<0.01 for both) systolic and diastolic BP; lower (p<0.01) pup weight; higher dam plasma homocysteine (p<0.05) and dam and offspring malondialdehyde (MDA) (p<0.01), lower (p<0.05) placental and offspring liver DHA and higher (p<0.01) tumor necrosis factor–alpha (TNF–ά) levels as compared to control. Individual micronutrient supplementation did not offer much benefit. In contrast, combined supplementation lowered systolic BP, homocysteine, MDA and placental TNF-ά levels in dams and liver MDA and protein carbonyl in the offspring as compared to PIH group. Conclusion Key constituents of one carbon cycle (folic acid, vitamin B12 and DHA) may play a role in reducing oxidative stress and inflammation in preeclampsia.

Abstract
PURPOSE Previous investigations have suggested a strong association between sleep-disordered breathing (SDB) during pregnancy and perinatal outcomes. However, the results of the following replication studies were not always concordant. Therefore, this meta-analysis was conducted to evaluate the more reliable estimate. METHODS A systematic literature search was performed on PubMed, Springer Link, and EMBASE to identify all eligible studies published before August 2013. Summary odds ratios (ORs) and 95% confidence intervals (CIs) were calculated using fixed or random effects model. RESULTS A total of 24 publications met the inclusion criteria and were included in this meta-analysis. Findings demonstrated that moderate-to-severe SDB during pregnancy was associated with gestational diabetes mellitus (OR=1.78; 95% CI, 1.29 to 2.46), pregnancy-related hypertension (OR=2.38; 95% CI, 1.63 to 3.47), preeclampsia (OR=2.19; 95% CI, 1.71 to 2.80), preterm delivery (OR=1.98; 95% CI, 1.59 to 2.48), low birth weight (OR=1.75; 95% CI, 1.33 to 2.32), neonatal intensive care unit (NICU) admission (OR=2.43; 95% CI, 1.61 to 3.68), intrauterine growth restriction (OR=1.44; 95% CI, 1.22 to 1.71), and Apgar score of <7 at 1 min (OR=1.78; 95% CI, 1.10 to 2.91) based on all studies but not gestational age and birth weight. CONCLUSIONS This meta-analysis revealed that moderate-to-severe SDB during pregnancy may be associated with most of adverse perinatal outcomes. Further well-designed studies are warranted to confirm our findings.
