Urinary concentration of Cathepsin D as a relievable marker of preeclampsia. Pregnancy Hypertens 2024; 36:101116. [PMID: 38408407 DOI: 10.1016/j.preghy.2024.101116] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/09/2023] [Revised: 01/15/2024] [Accepted: 02/17/2024] [Indexed: 02/28/2024]
Abstract
BACKGROUND The early and accurate diagnosis of preeclampsia is crucial to avoid serious complications for both the mother and baby. However, the current diagnostic methods are limited, and there is a need for new diagnostic biomarkers. Previous studies have shown that cathepsin D (CTD) participates in the pathophysiology of preeclampsia and is present in urine samples, making it a potential biomarker for the disease. This study aimed to compare urinary and serum levels of CTD in preeclamptic and normotensive women and analyze its potential role as a diagnostic biomarker in preeclampsia. METHODS The study included thirty-nine patients with preeclampsia and twelve normotensive pregnant women as controls. Biomarkers were determined using Multiplex Assay kit, and serum prolactin (Prl) and urinary TNF-α levels were also evaluated. Statistical analysis was conducted using the Mann-Whitney U test. RESULTS We found that urinary and serum CTD levels were significantly higher in the preeclampsia group than in the normotensive group, suggesting that CTD could be a diagnostic biomarker for preeclampsia. No significant differences were found in the levels of serum prolactin or urinary TNF-α between the two groups. CONCLUSIONS The study provides evidence that non-invasive biological samples such as urine can be used to improve new therapeutic strategies for the early management of preeclampsia.

Abstract
INTRODUCTION Intracranial aneurysms (IAs) occur in 3-5% of the general population and are characterized by localized structural deterioration of the arterial wall with loss of internal elastic lamina and disruption of the media. The risk of incidence and rupture of aneurysms depends on age, sex, ethnicity, and other different factors, indicating the influence of genetic and environmental factors. When an aneurysm ruptures, there is an estimated 20% mortality rate, along with an added 30-40% morbidity in survivors. The alterations in hormonal levels can influence IAs, while the rupture of an aneurysm can have various impacts on endocrine pathways and affect their outcome. AREA COVERED This review explores the reciprocal relationship between endocrinological changes (estrogen, growth hormone, and thyroid hormones) and IAs, as well as the effects of aneurysm ruptures on endocrine fluctuations. EXPERT OPINION Based on the data presented in this paper, we recommend further exploration into the influence of hormones on aneurysm formation and rupture. Additionally, we propose conducting endocrine assessments for patients who have experienced a rupture of IAs. Monitoring hormonal changes in patients with IAs could serve as a potential risk factor for rupture, leading to interventions in the approach to managing IAs.

Abstract
OBJECTIVES To compare the postpartum shock index (SI) values between pregnant women with hypertensive disease of pregnancy (HDP) and normotensive controls. METHODS The present study was conducted in Ankara City Hospital Perinatology Clinic. Postpartum SI was compared between the pregnant women with HDP (n=217) and normotensive controls (n=219). A logistic regression analysis was performed to assess the independent predictors of maximum SI ≥1. Finally, a ROC analysis was performed to calculate optimal cut-off values for postpartum SI's measured at different periods in the prediction of postpartum Hb (hemoglobin) decrease ≥2 g/dL. RESULTS Peripartum SI (p<0.001), 15th min SI (p<0.001), 30th min SI (p<0.001), 2nd h SI (p<0.001), 6th h SI (p) of the HDP group (p<0.001) and max SI (p<0.001) values were found to be significantly lower in the study group. A weak positive and statistically significant correlation was found between the maximum SI and the decrease in Hb ≥2 g/dL (r=0.209; p=0.002). Optimal cutoff values for SI were; 0.7 at peripartum 0.7 at 15 min, 0.73 at 30 min, 0.6 at 2 h, and 0.7 at 6 h, respectively. CONCLUSIONS Clinically significant blood loss may develop at lower SI values in hypertensive pregnant women.

Longitudinal 8-Epi-Prostaglandin F2-Alpha and Angiogenic Profile Mediator Evaluation during Pregnancy in Women with Suspected or Confirmed Pre-eclampsia. Biomedicines 2024; 12:433. [PMID: 38398035 PMCID: PMC10886743 DOI: 10.3390/biomedicines12020433] [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: 12/19/2023] [Revised: 01/31/2024] [Accepted: 02/05/2024] [Indexed: 02/25/2024] Open
Abstract
Background: In this exploratory study, we aimed to evaluate the dynamics of angiogenic [soluble fms-like tyrosine kinase-1 (sFlt-1), placental growth factor (PlGF), soluble Endoglin (sEng), and sFlt-1/PlGF, PlGF/sFlt-1, and sEng/PlGF ratios] and oxidative stress [8-epi-prostaglandin F2 alpha (8-epi-PGF2α) and 8-epi-PGF2α/PlGF ratio] mediator levels in women with suspected or confirmed pre-eclampsia (PE) at least two times during pregnancy. We also wanted to identify the possible correlations between 8-epi-PGF2α and angiogenic mediator levels at the time of inclusion of pregnant women. Methods: We included 40 pregnant women with suspected or confirmed PE, with a mean age of 29 years (range between 18 and 41 years) and gestational age between 18 and 28 weeks at inclusion in this study. The Enzyme-Linked Immunosorbent Assay (ELISA) method to measure the levels of serum angiogenic and oxidative stress mediators was used. Results: The evaluation of baseline sFlt-1/PlGF ratios using a cut-off of 38 suggested that 25 pregnant women had a sFlt-1/PlGF ratio of >38 (sFlt-1/PlGF ratio of >38 group) and 15 had a sFlt-1/PlGF ratio of ≤38 (sFlt-1/PlGF ratio of ≤38 group). The increases in sFlt-1/PlGF ratio in the sFlt-1/PlGF ratio of >38 group were caused by both an increase in sFlt-1 (2.04-fold) and a decrease in PlGF levels (2.55-fold). The 8-epi-PGF2α median levels were higher in the sFlt-1/PlGF ratio of >38 group (1.62-fold). During follow-up after pregnancy, we observed that the mean values of sFlt-1 and sEng and the median values of 8-epi-PGF2α and sFlt-1/PlGF, sEng/PlGF, and 8-epi-PGF2α/PlGF ratios increased directly proportional to gestational age for each measurement time until delivery in both groups. For five women who had a sFlt-1/PlGF ratio ≤38 at inclusion, sFlt-1/PlGF ratio was observed to increase to >38 later in pregnancy. We observed that, in the sFlt-1/PlGF ratio >38 group, baseline 8-epi-PGF2α levels better correlated with angiogenic mediator levels. Conclusions: Our study shows that 33.33% of pregnant women evaluated for suspected or confirmed PE with a sFlt-1/PlGF ratio of ≤38 displayed a rise in sFlt-1/PlGF ratio in subsequent weeks. In addition, together with angiogenic mediators, 8-epi-PGF2 α can be utilized as an independent predictor factor to help clinicians identify or predict which pregnant women will develop PE.

Abstract
The comet assay-based in vitro DNA repair assay has become a common tool for quantifying base excision repair (BER) activity in human lymphocytes or cultured cells. Here, we optimized the protocol for studying BER in human placental tissue because the placenta is a non-invasive tissue for biomonitoring of early-life exposures, and it can be used to investigate molecular mechanisms associated with prenatal disorders. The optimal protein concentration of placental protein extracts for optimal damage recognition and incision was 2 mg protein/mL. The addition of aphidicolin did not lead to reduced non-specific incisions and was, therefore, not included in the optimized protocol. The interval between sample collection and analysis did not affect BER activity up to 70 min. Finally, this optimized protocol was tested on pre-eclamptic (PE) placental tissues (n = 11) and significantly lower BER activity in PE placentas compared to controls (n = 9) was observed. This was paralleled by a significant reduction in the expression of BER-related genes and increased DNA oxidation in PE placentas. Our study indicates that BER activity can be determined in placentas, and lower activity is present in PE compared with healthy. These findings should be followed up in prospective clinical investigations to examine BER's role in the advancement of PE.

Abstract
BACKGROUND Preeclampsia is associated with the incidence of common fetal problems including intra-uterine growth restriction (IUGR), premature delivery oligohydramnios, placental abruption, fetal discomfort, and intrauterine fetal death. Pregnant women are not well-informed about preeclampsia, including its symptoms, risk factors, and consequences. The aim of the current study is to evaluate the awareness of preeclampsia and its associated factors among women in the Al Baha region, Saudi Arabia. METHODOLOGY An observational cross-sectional design was employed to assess the awareness of preeclampsia and its associated factors among women in the Al Baha region of Saudi Arabia. Data was collected from April 2023 to September 2023. A questionnaire was designed to gather information on participants' sociodemographic characteristics (such as age, educational level, and residency) and their awareness of preeclampsia, including knowledge about signs/symptoms, risk factors, and complications. RESULTS In the current study, we included 485 pregnant women. The majority of participants were aged 40 years or older (37.5%), followed by those aged 35-39 (20.4%). Among the participants, 70.9% confirmed that they had heard about pre-eclampsia before. The most common signs and symptoms were high blood pressure (47.4%), increased protein in urine (40.2%), continuous headache (39.2%), and vomiting/nausea (40.0%). Participants demonstrated awareness of obesity (29.7%), diabetes mellitus (35.5%), chronic hypertension (47.0%), and chronic kidney disease (31.3%) as major risk factors. Participants were aware of potential risks such as kidney disorders (34.6%), heart disorders (23.7%), and preterm delivery (50.9%). The analysis reveals that younger participants below 20 years old (3.3%) and lower educational levels (5.6%) had lower awareness of preeclampsia compared to older age groups. CONCLUSION The findings of this study highlight a reasonable level of preeclampsia awareness and knowledge among Saudi Arabian women residing in the Al Baha region. While the majority of participants were familiar with preeclampsia, there were significant knowledge gaps regarding the precise symptoms, risk factors, and consequences of the condition.

Abstract
INTRODUCTION Preeclampsia (PE) arises due to defective spiral artery remodelling which may be due to deficient migration of trophoblast cells. Migration of human endothelial cells has been shown to be promoted via Hydrogen sulphide(H2S)/Rho GTPase Rac1 axis. This novel role of H2S and its downstream processes have not yet been studied in the development and function of the placental trophoblast cells. METHODS Placental tissues were obtained post-delivery from consented preeclamptic and normotensive mothers (n = 60). The protein expression levels of cystathionine-gamma-lyase (CSE) and cystathionine-beta-synthase (CBS) along with its downstream migratory molecules were compared in both the arms. The pro-migratory role of H2S was investigated in a first trimester placental cell line. RESULTS H2S promoted the migration of trophoblast cells in a Rho GTPase dependent manner mediated by actin cytoskeleton reorganization. The reduced levels of H2S producing enzymes in the PE placentae along with decreased levels of Rho GTPases (Rac1 and Rho A) corroborate the results of PAG and AOAA treatment in down regulating the Rho GTPases in the in vitro grown placental cultures. Reduction of the migratory potential of trophoblastic cells caused due to hypoxia/reoxygenation was rescued by upregulating the H2S expression with the use of NaHS as a H2S donor. DISCUSSION Exogenous H2S increases the migratory potential of the placental cells in culture conditions and also post hypoxia/reoxygenation injury. H2S as a gaso-transmitter holds a great potential as a therapeutic agent. Its long-term effects need to be investigated using model systems (rat/mouse) of PE following it up with clinical regulatory trials.

Abstract
Preeclampsia increases the risk of pregnancy-related complications, nevertheless a successful spiral vessel remodeling, and trophoblast invasion reduces disorders of pregnancy. Matrix metalloproteinase-2 (MMP-2) clears the path for trophoblast invasion, and activation of MMP-2 largely depends on extracellular matrix metalloproteinases inducer (EMMPRIN) protein. This study aimed to investigate EMMPRIN gene polymorphism and MMP-2 activity in preeclampsia patients. Archival whole blood and serum samples of 74 preeclampsia and 66 normotensive pregnant women age-matched were used in this case-control study. Genomic DNA was extracted from the whole blood samples and EMMPRIN gene amplified with specific primers following fragments sequence mutation analysis. Serum MMP-2 activity was determined using enzyme-linked immunosorbent assay (ELISA) and socio-demographic data of participants retrieved from the database. Age of preeclampsia patients (32.78 ± 6.39) years and body mass index (BMI) (33.09 ± 7.27) kg/m2 compared with the normotensive counterparts (32.33 ± 5.56) years and (32.33 ± 5.56) kg/m2,respectively, were not statistically significant (P > 0.05). Serum matrix metalloprotease-2 (MMP-2) activity was significantly reduced in preeclampsia group (16.34 ± 7.07) compared with the normotensives (25.63 ± 4.56) (P < 0.001), and rs424243T/G variant (55.6%) was overrepresented among the cases compared with the normotensives (16.7%). The single-nucleotide polymorphism T/G was found to be associated with preeclampsia (odds ratio [OR] = 7.63; 95% confidence interval [CI] = 3.95-14.75; P < 0.0001). Decreased activity of MMP-2 and rs424243T/G SNP of EMMPRIN gene was reported in preeclampsia. These preliminary data warrant a further investigation into the relationship between EMMPRIN gene polymorphism and MMP-2 activity in preeclampsia.

Abstract
Pre-eclampsia is a severe pregnancy-related complication that manifests as a syndrome with multisystem involvement and damage. It has significantly grown in frequency during the past 30 years and could be considered as one of the major causes of maternal and fetal morbidity and mortality. However, the specific etiology and molecular mechanisms of pre-eclampsia are still poorly known and could have a variety of causes, such as altered angiogenesis, inflammations, maternal infections, obesity, metabolic disorders, gestational diabetes, and autoimmune diseases. Perhaps the most promising area under investigation is the imbalance of maternal angiogenic factors and its effects on vascular function, though studies in placental oxidative stress and maternal immune response have demonstrated intriguing findings. However, to determine the relative importance of each cause and the impact of actions aiming to significantly reduce the incidence of this illness, more research is needed. Moreover, it is necessary to better understand the etiologies of each subtype of pre-eclampsia as well as the pathophysiology of other major obstetrical syndromes to identify a clinical tool able to recognize patients at risk of pre-eclampsia early.

Abstract
Preeclampsia is a heterogeneous and multiorgan cardiovascular disorder of pregnancy. Here, we report the development of a novel strip-based lateral flow assay (LFA) using lanthanide-doped upconversion nanoparticles conjugated to antibodies targeting two different biomarkers for detection of preeclampsia. We first measured circulating plasma FKBPL and CD44 protein concentrations from individuals with early-onset preeclampsia (EOPE), using ELISA. We confirmed that the CD44/FKBPL ratio is reduced in EOPE with a good diagnostic potential. Using our rapid LFA prototypes, we achieved an improved lower limit of detection: 10 pg ml-1 for FKBPL and 15 pg ml-1 for CD44, which is more than one order lower than the standard ELISA method. Using clinical samples, a cut-off value of 1.24 for CD44/FKBPL ratio provided positive predictive value of 100 % and the negative predictive value of 91 %. Our LFA shows promise as a rapid and highly sensitive point-of-care test for preeclampsia.

Int J Mol Sci 2023; 24:ijms24076744. [PMID: 37047717 PMCID: PMC10095124 DOI: 10.3390/ijms24076744] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/30/2023] [Revised: 03/13/2023] [Accepted: 03/24/2023] [Indexed: 04/08/2023] Open
Abstract
One of the main causes of maternal and neonatal morbidity and mortality is pre-eclampsia. It is characterized by a high sFlt1/PlGF ratio, according to prior research. Pregestational diseases in mothers may increase the risk of developing pre-eclampsia. Only a few studies have looked at the connection between maternal comorbidities before conception and the sFlt1/PlGF ratio. The most recent information regarding the association between maternal pregestational diseases and the ratio of sFlt1/PlGF is described in this review. The paper also examines current research suggesting that changes in pregnancy hormones and metabolites are related to a high sFlt1/PlGF ratio. Certain maternal disorders have been found to dramatically raise sFlt-1 and sFlt1/PlGF levels, according to an analysis of the literature. There is still debate about the data on the association between the sFlt1/PlGF ratio and maternal disorders such as HIV, acute coronary syndromes, cardiovascular function in the mother between 19 and 23 weeks of pregnancy, thyroid hormones, diabetes, and cancer. Additional research is needed to confirm these findings.

Abstract
BackgroundPreeclampsia is a disease with far-reaching consequences that extend beyond the immediate postpartum period and have a significant impact later in life. Preeclampsia exerts an effect on most organ systems in the body. These sequelae are mediated in part by the incompletely elucidated pathophysiology of preeclampsia and the associated vascular changes.ContentCurrent research focuses on unraveling the pathophysiology of preeclampsia with the goal of implementing accurate screening and treatment modalities based on disease development and progression. Preeclampsia causes significant short- and long-term maternal morbidity and mortality, not only in the cardiovascular system but also in other organ systems throughout the body. This impact persists beyond pregnancy and the immediate postpartum period.SummaryThe goal of this review is to discuss the current understanding of the pathophysiology of preeclampsia as it relates to the adverse health consequences in patients impacted by this disease, along with a brief discussion of ways to improve overall outcomes.

Abstract
Background Congo Red Dot Paper Test (CRDPT) appears to be a simple, cost-effective, non-invasive diagnostic tool for hypertensive disorders of pregnancy (HDP). The main objective of the study is to assess the effectiveness of CRDPT in detecting HDP. Methods This is a systemic review and meta-analysis of published studies on the effectiveness of CRDPT in the detection of HDP. The study was conducted in line with the PRISMA-DTA guidelines. The PICOS framework was used to search for relevant articles using Medline, PubMed, Google Scholar, Web of Science, and the Cochrane Library databases. The articles were screened against a set of inclusion and exclusion criteria and analysed using the Review Manager 5.4 software. Results A title, abstract and full article screening was conducted on 18,153 potential articles based on the inclusion and exclusion criteria. The screening yielded five articles for meta-analysis. The total number of normotensive pregnant women (n = 3,380) in the included studies was five times higher than the total number of women with pre-eclampsia (n = 535). A difference between the HDP and normotensive group was noted. This is indicated by a significantly decreased in the effectiveness of CRDPT in detecting HDP as compared to normotensive group [Risk Ratio (RR) = 6.32 (2.17, 18.43) p < 0.00001]. The included studies had a high nature of heterogeneity (I 2 = 98%, p < 0.00001) partially due to different study designs included in the analysis and different regions where studies were conducted given that none of these studies were conducted in African countries where HDP is prominent. Conclusions According to results generated from 5 studies in this meta-analysis, it was found that CRDPT might not be effective in the detection of hypertensive disorder of pregnancy. Moreover, more research, especially in African women where hypertensive disorders of pregnancy are prevalent, are re-quired to ascertain these findings.

Abstract
Background Preeclampsia (PE) is a multi-factor and multi-mechanism disease, which may jeopardize the life safety of affected pregnant women and fetuses. Our study aimed to detect the potential molecular indicators of PE that might be helpful for its diagnosis and treatment. Methods Methylation assay of PE and normal pregnancies placental biopsies was analyzed using the Illumina Human Methylation-27 Assay. Differentially expressed genes (DEGs) were analyzed using R-DESeq2 software. Subsequently, the relationship between DNA methylation genes and DEGs were evaluated. Furthermore, immunohistochemical (IHC) and quantitative reverse transcription polymerase chain reaction (qRT-PCR) validation analyses were conducted for the hub genes. Results These hub genes (including PLXNB1, PMCH, PPARG, GOPC, CD79A, and MME) were found to be differentially methylated genes and DEGs. Further analysis revealed that PPARG, CD79A, and PLXNB1 may be diagnostic gene markers for PE; down-regulation of PPARG expression was closely correlated with the development of PE. The IHC analysis demonstrated that the expression levels of PLXNB1, PMCH, GOPC, CD79A, and MME genes were increased, whereas that of PPARG was decreased in PE tissues. The PCR results showed that PLXNB1, PMCH, GOPC, CD79a, and MME were upregulated, whereas PPARG was downregulated. The results of the 2 experiments were consistent with those of bioinformatics analysis. Conclusions The molecular indicators identified in this study could facilitate the development of potential biomarkers and therapeutic targets for PE.

Serum Collected from Preeclamptic Pregnancies Drives Vasoconstriction of Human Omental Arteries-A Novel Ex Vivo Model of Preeclampsia for Therapeutic Development.

Abstract
New-onset maternal hypertension is a hallmark of preeclampsia, driven by widespread endothelial dysfunction and systemic vasoconstriction. Here, we set out to create a new ex vivo model using preeclamptic serum to cause injury to the endothelium, mimicking vascular dysfunction in preeclampsia and offering the potential to evaluate candidate therapeutic interventions. Human omental arteries were collected at caesarean section from normotensive pregnant patients at term (n = 9). Serum was collected from pregnancies complicated by preterm preeclampsia (birth < 34 weeks’ gestation, n = 16), term preeclampsia (birth > 37 weeks’ gestation, n = 5), and healthy gestation-matched controls (preterm n = 16, term n = 12). Using wire myography, we performed ex vivo whole vessel assessment where human omental arteries were treated with increasing doses of each serum treatment (2−20%) and vasoreactivity was assessed. All pregnant serum treatments successfully drove vasoconstriction; no significant difference was observed in the degree of vasoconstriction when exposed to preeclamptic or control serum. We further demonstrated the ability of esomeprazole (a candidate therapeutic for preeclampsia; 0.1−100 µM) to drive vasorelaxation of pre-constricted vessels (only with serum from preeclamptic patients). In summary, we describe a novel human physiological model of preeclamptic vascular constriction. We demonstrate its exciting potential to screen drugs for their therapeutic potential as treatment for vasoconstriction induced by preeclampsia.

Abstract
Preeclampsia (PE), an inflammatory state during pregnancy, is a significant cause of maternal and fetal morbidity and mortality. Adverse outcomes associated with PE include hypertension, proteinuria, uterine/placental abnormalities, fetal growth restriction, and pre-term birth. Women with obesity have an increased risk of developing PE likely due to impaired placental development from altered metabolic homeostasis. Inflammatory cytokines from maternal adipose tissue and circulating cholesterol have been linked to systemic inflammation, hypertension, and other adverse outcomes associated with PE. This review will summarize the current knowledge on the role of nutrients, obesity, and cholesterol signaling in PE with an emphasis on findings from preclinical models.

Abstract
Disruption of normal intrauterine brain development is a significant consequence of premature birth and may lead to serious complications, such as neonatal brain injury (NBI). This prospective case-control longitudinal study aimed at determining the levels and prognostic value of serum activin A during the first three days of life in human premature neonates which later developed NBI. It was conducted in a single tertiary hospital and eligible participants were live-born premature (<34 weeks) neonates. Each case (n = 29) developed NBI in the form of an intraventricular haemorrhage, or periventricular leukomalacia, and was matched according to birth weight and gestational age to one neonate with normal head ultrasound scans. Serum activin A levels in both groups showed a stable concentration during the first three days of life as no difference was observed within the two groups from the first to the third day. Neonates diagnosed with NBI had significantly higher activin A levels during the first two days of life compared to control neonates and its levels correlated to the severity of NBI during the second and third day of life. Although serum activin A on the second day was the best predictor for neonates at risk to develop NBI, the overall predictive value was marginally fair (area under the ROC-curve 69.2%). Activin A, in combination with other biomarkers, may provide the first clinically useful panel for the early detection of premature neonates at high risk of NBI.

Abstract
We present the case of a 35-year-old female who presented to the emergency department (ED) shortly after undergoing a cesarean section with dyspnea. Her vitals on admission revealed hypertension, tachypnea, bradycardia, and suboptimal oxygen saturation. Physical examination was remarkable for crackles in the lower lung fields. Laboratory results revealed elevated lactate dehydrogenase (LDH), pro-B-type natriuretic peptide (pro-BNP), and D-dimer levels. A CT angiogram showed no pulmonary emboli, and an echocardiogram revealed a normal ejection fraction and no diastolic dysfunction. A chest X-ray was significant for pulmonary edema and vascular congestion. The patient was diagnosed with respiratory distress due to pulmonary edema that was secondary to hypertension. This unusual case report seeks to highlight the idea that elevated blood pressure in postpartum women should warrant careful monitoring, as its consequential manifestations may be lethal. Additionally, pulmonary edema secondary to hypertension should be considered as a differential in either postpartum or peripartum women who present with respiratory symptoms and elevated blood pressure.

Abstract
Preeclampsia (PE) is a major cause of maternal and new-born morbidity and mortality. Angiogenic factors contribute a major role in the vascular dysfunction associated with PE. We investigated the circulating levels of vascular endothelial growth factor (VEGF), placental growth factor (PlGF) and soluble Feline McDonough Sarcoma (fms)-like tyrosine kinase-1 (sFlt1), their association with PE and diagnostic performance of disease among pregnant women in Uganda. Using a case-control study design, 106 women with PE and 106 with normal pregnancy were enrolled. Demographic and clinical characteristics, and anticoagulated blood samples were collected from participants. Plasma VEGF, PlGF and sFlt1 levels were measured using Luminex and enzyme linked immunosorbent assays (ELISA). Conditional logistic regression was used to explore association of angiogenic factors with PE and receiver operating characteristic analysis was performed to investigate PE diagnostic performance. Levels of VEGF and PIGF were significantly lower in cases compared to controls (VEGF: median = 0.71 pg/ml (IQR = 0.38-1.11) Vs 1.20 pg/ml (0.64-1.91), p-value<0.001 and PlGF: 2.20 pg/ml (1.08-5.86) Vs 84.62 pg/ml (34.00-154.45), p-value<0.001). Plasma levels of sFlt1 were significantly higher in cases than controls (median = 141.13 (71.76-227.10) x103 pg/ml Vs 19.86 (14.20-29.37) x103 pg/ml). Increasing sFlt1 levels were associated with increased likelihood of PE (aOR = 4.73; 95% CI, 1.18-19.01; p-value = 0.0287). The sFlt1/PlGF ratio and sFlt1 had a better performance for diagnosis of PE, with AUC = 0.95 (95% CI, 0.93-0.98) followed by PlGF with AUC = 0.94 (95% CI, 0.91-0.97). Therefore, sFlt1, sFlt1/PlGF ratio and PlGF are potential candidates for incorporation into algorithms for PE diagnosis in the Ugandan population.

Abstract
INTRODUCTION To assess renal and hepatic functions along with the redox state in preeclampsia (PE) and gestational diabetes mellitus (GDM) pregnancies. DESIGN AND METHOD The study was conducted on 33 PE (mean age = 30 ± 5 years), 33 GDM (mean age = 30 ± 6 years) and age, gravida, parity, and ethnicity matched 25 normal pregnancies (NP). Biomarkers of redox status, renal and hepatic functions; aspartate transaminase (AST), alanine transaminase (ALT), alkaline phosphatase (ALP), bilirubin, urea, blood urea nitrogen (BUN), creatinine, uric acid, lipid peroxidation (MDA), total thiols (TSH), radical scavenging activities and ferric reducing antioxidant potentials of serum were measured. RESULTS Higher urea, BUN, uric acid, creatinine and overexpressed AST, ALT, ALP was observed in PE (p <0.03-p<0.001), whereas in GDM elevation in creatinine and ALT activity were only statistically significant (p <0.01) in comparison to NP. Diminished antioxidant/radical scavenging potentials, TSH content and increased MDA were noted in both the diseased pregnancies when compared with NP with statistically significant variables ranged from p <0.04-p <0.0001. CONCLUSION Our data suggest that PE has detrimental effects on renal and hepatic functions while GDM are prone to malfunctioned liver and kidney performances. Impaired redox state may be one of the reasons of altered physiological process in PE and GDM pregnancies. Results may be used to monitor the efficiency and efficacy of antioxidant supplementation, recently suggested for PE and GDM patients.

Clin Chim Acta 2020; 510:781-786. [PMID: 32941837 DOI: 10.1016/j.cca.2020.09.013] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/07/2020] [Revised: 08/23/2020] [Accepted: 09/09/2020] [Indexed: 12/23/2022]
Abstract
BACKGROUND Neonatal brain injury (NBI) is a serious adverse outcome in premature neonates. We sought to determine the levels and prognostic value of serum S100B during the first three days of life in premature neonates (<34 weeks) that later developed NBI in the form of either intraventricular hemorrhage (IVH) or periventricular leukomalacia (PVL). METHODS This is a prospective case - control longitudinal study. Each case (n = 29) was matched according to birthweight and gestational age to one neonate with normal head ultrasound scans. RESULTS Neonates with NBI, had significantly higher S100B concentration during the first three days of life. In both groups S100B was significantly higher on the first day when compared to the next two days of life showing a downwards trend. Serum S100B on the first day was the best predictor for adverse neonatal outcome such as death or II-IV IVH grade. A cut-off value of 10.51 ng/ml serum S100B performed a sensitivity of 100% and a specificity of 93.9% to predict adverse neonatal outcome. CONCLUSION Further research on the predictive value of serum S100B regarding NBI in premature neonates is of great interest and may provide the first clinically useful biomarker for early detection of neonates at high risk.

Abstract
Hemodynamic and hormonal changes during pregnancy can increase rates of formation, growth, and rupture of intracranial aneurysms (IA), and the increased incidence of subarachnoid hemorrhage (SA) in pregnant patients represents a risk to both mother and fetus. Despite this, management and treatment guidelines have not been defined for this patient population. In most instances, treatment decisions are made on a case-by-case basis with varying degrees of input from subspecialists. Important considerations, such as aneurysm location, morphology, size, growth pattern, and patient characteristics have not been presented in a management algorithm in the context of the pregnant patient. Given limited and controversial literature describing management of IAs in pregnant patients, we performed a systematic literature review. We then describe our multidisciplinary team approach and provide analysis of existing literature to provide guidelines for the management of the pregnant patient with an IA. A systematic review was undertaken to identify studies describing the management of IAs in the pregnant patient using the PubMed database. Overall maternal and fetal morbidity and mortality rates were determined. Data was analyzed for 1537 patients, including 1115 (73%) pregnant with ruptured intracranial aneurysms. In most cases, these aneurysms were managed conservatively (77%; 781/1013); however, when treatment was provided, surgical clipping was the most common modality (15%; 149/1013). Overall maternal outcomes were reported for 934 cases with morbidity and mortality rates of 5% (42/934) and 21% (194/934), respectively. Overall fetal outcomes were reported for 114 cases with morbidity and mortality rates of 10% (12/119) and 8% (9/119), respectively. Pregnancy-associated physiological changes likely elevate the risk of intracranial aneurysm formation, growth, and rupture. Treatment for aneurysms and SAs is safe and effective during pregnancy when risks are properly mitigated. Due to the complexity of care, such patients should be treated using a collaborative, interdisciplinary approach by a multidisciplinary team.

Abstract
OBJECTIVES Preeclampsia (PE) and fetal growth restriction (FGR) have abnormal placental implantation and endothelial dysfunction in common. However, their etiologies are not well understood. Both heat shock protein 70 (Hsp70) and nitric oxide (NO) are suggested to play a major role in the regulation of maternal and fetoplacental hemodynamics. In this study, the association of PE with FGR and Hsp70 or NO was analyzed. METHODS A total of 30 cases of PE, 25 cases of PE complicated with FGR and 50 cases of normal pregnant women were chose, and PE and normal animal models were constructed. Subsequently, the levels of Hsp70 and NO in serum and placental tissues of humans and animals were measured and compared. Further, rats were injected with pLV-NC-shRNA, pLV-Hsp70-shRNA, pLV-EFIa-NC, and pLV-EFIa-Hsp70, respectively, the weight of each conceptus, number of pups, fetal crown to tail length, total weight of the placenta/fetus unit, and the content of NO were analyzed. RESULTS The expression of Hsp70 in serum and placental tissues of PE complicated with or without FGR group was increased, whereas the content of NO was decreased compared to the normal group. The fetal weight (FW) of the Hsp70 targeted suppression group was higher than the other two groups, whereas the placental weight (PW) was reversed. Also, NO synthase (NOS) expression was decreased in the Hsp70 over-expression group. CONCLUSIONS We speculated that the enhancement of Hsp70 might be related to the development of PE combined with FGR through inhibiting the synthesis of NOS.

Aurora kinase mRNA expression is reduced with increasing gestational age and in severe early onset fetal growth restriction. Placenta 2020; 95:53-61. [PMID: 32452402 DOI: 10.1016/j.placenta.2020.04.012] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/31/2020] [Revised: 04/05/2020] [Accepted: 04/20/2020] [Indexed: 11/20/2022]
Abstract
INTRODUCTION Oxidative damage and biochemical ageing are implicated in placental dysfunction and potentially fetal death. Cellular senescence may play a role in the pathophysiology of fetal growth restriction (FGR) and preeclampsia (PE). Aurora kinases (AURKA, B and C) are important regulators of cellular division in mitosis and meiosis with implications in cellular senescence. We aimed to investigate whether aurora kinase expression is altered with placental dysfunction or placental ageing. METHODS Placenta and blood was obtained across gestation from pregnancies complicated by PE, FGR or both PE and FGR, as well as gestation-matched control samples. Expression of AURKA, B and C mRNA was examined using real time qPCR in both the placenta and maternal circulation. RESULTS Placental aurora kinase expression decreased as gestation progressed: AURKA and AURKB were significantly reduced at 37-40 weeks, whereas AURKC was significantly reduced at 34-37 weeks, when compared to <34 weeks. In the maternal circulation, the mRNA level of AURKB was significantly reduced at >40 weeks compared to <34 weeks gestation. A significant reduction in AURKC was seen in FGR pregnancies <34 weeks compared to gestation-matched controls. CONCLUSION Placental AURK expression is reduced with increased gestation. Circulating AURKB mRNA reduces at >40 weeks gestation, when compared to <34 weeks. AURKC is significantly reduced in placentas from pregnancies complicated by severe early onset (<34 weeks) FGR compared with gestation-matched controls. The functional role of aurora kinase in the placenta and in gestational age warrants further investigation.

Abstract
Background Early antiretroviral therapy (ART) during pregnancy has dramatically reduced the risk of perinatal HIV transmission. However, studies have shown an association between premature delivery and the use of ART during pregnancy (particularly protease inhibitor (PI)-based therapies), which could be explained by placental dysfunction. The objective of this study was to evaluate the association of ART (class, duration of exposure and time of initiation) with placental function by using angiogenic factors placental growth factor (PlGF) and soluble fms-like tyrosine kinase-1 (sFlt-1) as biomarkers. Methods Clinical and biological data from 159 pregnant women living with HIV were analyzed. Levels of each biomarker were measured in the first and second trimester of pregnancy. After logarithmic transformation, we compared these using generalized estimating equations according to (a) the type of ART; (b) the duration of exposure to ART; and (c) the time of initiation of ART. Results After adjusting for variables such as ethnicity, maternal age, gestational age, body mass index, parity, smoking status, and sex of the fetus, we found no significant association between the class of ART (PI-based or not) and serum concentrations of PlGF or sFlt-1. Furthermore, no significant association was found between biomarker levels and the duration of ART exposure or the timing of ART initiation (pre- or post-conception). Conclusions This study suggests that first and second trimester angiogenic factor levels are not significantly associated with ART, regardless of the duration or type (with or without PI). These observations seem reassuring when considering the use of ART during early pregnancy.

Abstract
Background Pre-eclampsia (PE) is one of the leading causes of maternal morbidity and mortality globally. Adequate knowledge about a disorder contributes greatly to its prevention, control and management. This study assessed the level of knowledge of PE and evaluated the factors associated with knowledge adequacy among pregnant women attending antenatal care at a University Hospital in Kumasi-Ghana. Methods This cross-sectional study was conducted at the University Hospital in Kumasi, Ghana. A validated closed-ended questionnaire was used to collect socio-demographic information and history of PE. Knowledge of PE was assessed based on a series of questions regarding the awareness, signs/symptoms, risk factors and complications of PE. Responses were scored percentage-wise and grouped into low (< 60%), moderate (60–80%) and high (80–100%). Knowledge score was then re-stratified into adequate (% score of ≥60%) and inadequate knowledge of PE (% score of < 60%). Results The prevalence of inadequate and adequate knowledge of PE was 88.6% (mean score = 55.5 ± 4.3%) and 11.4% (mean score = 76.3 ± 5.9%), respectively. For participants with adequate knowledge of PE, 9.1% (mean score = 67.4 ± 6.9%) and 2.3% (mean score = 85.2 ± 5.1%) had moderate and high knowledge, respectively. Using univariate logistic regression models, being older (> 35 years old) [cOR = 3.09, 95%CI (0.88–10.88), p = 0.049] and having a higher level of education (> SHS education) [cOR = 4.45, 95%CI (2.18–9.10), p < 0.0001] were significantly associated with greater odds of having adequate knowledge of PE. After controlling for potential confounders in multivariate logistic regression analysis, we found higher level of education to be independently associated with adequate knowledge of PE [aOR = 2.87, 95%CI (1.31–6.30), p = 0.008]. Conclusion The knowledge of PE among pregnant women in Ghana is low. The prominent factor that facilitates adequacy of knowledge of PE is higher level of education.

Abstract
Objective: To screen for novel predictive serum markers of preeclampsia (PE). Method: Blood samples were collected from seven women with PE and five with healthy pregnancies. Serum proteins were identified using isobaric tags for relative and absolute quantitation (iTRAQ) technology combined with liquid chromatography mass spectrometry analysis. The differentially expressed proteins in the PE samples were identified using the SwissProt database, and functionally annotated by gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) analyses. The upregulated proteins from iTRAQ result were verified by ELISA. Results: We identified 121 differentially expressed proteins, of which 76 were upregulated and 45 were downregulated, and 14 were differentially expressed by more than two-folds. The top GO terms for Cellular Components (CC) were high-density lipoprotein particles and plasma lipoprotein particles, defense response for Biological Processes (BP), and glycosaminoglycan binding, heparin binding and sulfur compound for Molecular functions (MF). The pathway hsa04979 for Cholesterol metabolism was significantly enriched among the upregulated proteins, while the structural domain was enriched in immunoglobulin subtype 2. The dysregulation of pregnancy-specific beta-1-glycoprotein 2 (PSG2) was confirmed by ELISA. Conclusion: PE pathogenesis is related to lipid metabolism and inflammation, and proteins related to these pathways are potential early diagnostic markers for PE.PSG2 may be a marker of PE.
