Abstract
OBJECTIVES To evaluate the correlation between maternal serum and urinary soluble Fms-like tyrosine kinase-1 (sFlt-1) and placental growth factor (PlGF) levels and to assess their potential value in preeclampsia and fetal growth restriction. STUDY DESIGN This case-control longitudinal prospective study was performed in 49 singleton pregnant women, divided into two clinical groups, low risk pregnancy (n = 23) and pregnancy complicated by preeclampsia (n = 26). Maternal serum and urinary sFlt-1 and PlGF levels were quantified by electrochemiluminescence. Every patient underwent an ultrasound for fetal biometry. Doppler assessment was done when estimated fetal weight was under the 10th centile. ROC curves were used to evaluate the predictive capability of serum and urinary angiogenic biomarkers and their ratios on preeclampsia. Linear regression was used to compare the values of serum and urinary sFlt-1 and PlGF and their ratios. RESULTS Urine biomarkers were positively associated with their serum values, being the best associated urinary PlGF (R2 = 0.73), which also showed the highest predictive capability of preeclampsia of urine biomarkers (AUC 0.866). The predictive capability of urinary sFlt-1 was much lower (AUC 0.640), but increased when adjusting by serum creatinine, a more precise parameter (AUC 0.863). CONCLUSIONS Urinary PlGF could be a lesser invasive alternative to circulating biomarkers to monitor pregnancies complicated with preeclampsia that need repeated controls of their pregnancy complication. Urinary sFlt-1 values need adjustment by serum creatinine to be reliable.

Detection of Urinary Misfolded Proteins for Imminent Prediction of Preeclampsia in Pregnant Women With Suspected Cases: Protocol for a Prospective Noninterventional Study. JMIR Res Protoc 2024; 13:e54026. [PMID: 38669061 PMCID: PMC11087858 DOI: 10.2196/54026] [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: 11/08/2023] [Revised: 03/19/2024] [Accepted: 03/21/2024] [Indexed: 04/28/2024] Open
Abstract
BACKGROUND Preeclampsia (PE) is one of the most common hypertensive diseases, affecting 2%-8% of all pregnancies. The high maternal and fetal mortality rates of PE are due to a lack of early identification of affected pregnant women that would have led to closer monitoring and care. Recent data suggest that misfolded proteins might be a promising biomarker for PE prediction, which can be detected in urine samples of pregnant women according to their congophilia (aggregated) characteristic. OBJECTIVE The main purpose of this trial is to evaluate the value of the urine congophilia-based detection of misfolded proteins for the imminent prediction of PE in women presenting with suspected PE. The secondary objectives are to demonstrate that the presence of urine misfolded proteins correlates with PE-related maternal or neonatal adverse outcomes, and to establish an accurate PE prediction model by combining misfolded proteins with multiple indicators. METHODS At least 300 pregnant women with clinical suspicion of PE will be enrolled in this prospective cohort study. Participants should meet the following inclusion criteria in addition to a suspicion of PE: ≥18 years old, gestational week between 20+0 and 33+6, and single pregnancy. Consecutive urine samples will be collected, blinded, and tested for misfolded proteins and other PE-related biomarkers at enrollment and at 4 follow-up visits. Clinical assessments of PE status and related complications for all participants will be performed at regular intervals using strict diagnostic criteria. Investigators and participants will remain blinded to the results. Follow-up will be performed until 42 days postpartum. Data from medical records, including maternal and fetal outcomes, will be collected. The performance of urine misfolded proteins alone and combined with other biomarkers or clinical variables for the prediction of PE will be statistically analyzed. RESULTS Enrollment started in July 2023 and was still open upon manuscript submission. As of March 2024, a total of 251 eligible women have been enrolled in the study and enrollment is expected to continue until August 2024. Results analysis is scheduled to start after all participants reach the follow-up endpoint and complete clinical data are collected. CONCLUSIONS Upon completion of the study, we expect to derive an accurate PE prediction model, which will allow for proactive management of pregnant women with clinical suspicion of PE and possibly reduce the associated adverse pregnancy outcomes. The additional prognostic value of misfolded proteins is also expected to be confirmed.

Abstract
Purpose To observe the effect of soya yoghurt (Soyghurt), which is high in flavonoid substance, on the expression of preeclampsia biomarkers (sFLT-1 and PLGF) on preeclampsia serum-induced trophoblast primary cell culture isolated from placental tissue. Methods The trophoblast primary culture was induced by preeclampsia serum (10%). The Soyghurt treatment was performed with 2.5%, 5%, and 7.5% Soyghurt supernatant concentrations in culture media. The expression of preeclampsia markers, sFLT-1 and PLGF, were evaluated using ELISA. Results Expression of sFLT-1 on preeclampsia-induced cell culture treated with Soyghurt was significantly lowered compared to the untreated group (p<0.01). However, no significant difference was observed in the PLGF levels of all groups induced by preeclampsia serum (p>0.05). Conclusion This study demonstrates the potential effect of Soyghurt's in balancing preeclampsia marker expression by inhibiting the expression of sFLT-1 in preeclampsia serum -induced trophoblast cells.

Abstract
INTRODUCTION Preeclampsia (PE) is a highly relevant pregnancy-related disorder. An early and accurate diagnosis is crucial to prevent major maternal and neonatal complications and mortality. Due to the association of kidney dysfunction with the pathophysiology of the disease, urine samples have the potential to provide biomarkers for PE prediction, being minimally invasive and easy to perform. Therefore, searching for novel biomarkers may improve outcomes. This narrative review aimed to summarize the scientific literature about the traditional and potential urinary biomarkers in PE and to investigate their applicability to screen and diagnose the disorder. METHODS A non-systematic search was performed in PubMed/MEDLINE, Scopus, and SciELO databases. RESULTS There is significant divergence in the literature regarding traditionally used serum markers creatinine, cystatin C, and albuminuria, accuracy in PE prediction. As for the potential renal biomarkers investigated, including vascular epithelial growth factor (VEGF), placental growth factor (PlGF), and soluble fms-like tyrosine kinase (sFlt-1), urinary levels of PlGF and sFtl-1/PlGF ratio in urine seem to be the most promising as screening tests. The assessment of the global load of misfolded proteins through urinary congophilia, podocyturia, and nephrinuria has also shown potential for screening and diagnosis. Studies regarding the use of proteomics and metabolomics have shown good accuracy, sensitivity, and specificity for predicting the development and severity of PE. CONCLUSION However, there are still many divergences in the literature, which requires future and more conclusive research to confirm the predictive role of urinary biomarkers in pregnant women with PE.

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
In normal pregnancy, the soluble form of FMS-like tyrosine kinase-1 (sFLT1)/ vascular endothelial growth factor receptor-1 (sVEGFR-1), a VEGF-trapping protein, is expressed in trophoblasts of the placenta, suggesting that it plays an important role in the physiological barrier between fetal and maternal angiogenesis, when stimulated with VEGF-A. In pathological conditions such as preeclampsia (PE), sFLT1 protein is abnormally overexpressed in trophoblasts and secreted into the serum, which could cause hypertension and proteinuria on the maternal side and growth retardation on the fetal side. Detection of an abnormal increase in serum sFLT1 during the early to middle stages of PE is essential for proper initiation of medical care. To carry out this screening for sFLT1, we developed an easier and relatively low-cost sandwich-type ELISA method using a single mixture of human serum sample with an anti-FLT1 antibody and heparin-beads, namely heparin-beads-coupled ELISA (HB-ELISA). This method takes only about 2 h, and the sFLT1 values were similar levels with commercially available recent ELISA kits: the serum sFLT1 protein was approximately 4.3-fold increased in severe PE compared with those in normal pregnancy.

Abstract
BACKGROUND Pre-eclampsia affects around 2-3% of all pregnancies, and is associated with potential serious complications for the woman and the baby. Once diagnosed, progression of the syndrome can be unpredictable, and decisions around timing of delivery need to take into account evolving maternal complications and perinatal morbidity. Novel prognostic models and blood biomarkers for determination of need for delivery in pregnancies with pre-eclampsia are now emerging. OBJECTIVE The objective of the study was to establish a prognostic model to inform optimal timing of delivery in women with late preterm pre-eclampsia (34+ 0 to 36+ 6 weeks' gestation), comparing novel candidate biomarkers (e.g. placental growth factor) with clinical and routinely collected blood/urinary parameters [incorporated into the PREP-S (Prediction models for Risk of Early-onset Pre-eclampsia - Survival) model] to determine clinically indicated need for delivery for pre-eclampsia (or related complications) within 7 days of assessment. METHODS Prospective recruitment of women in whom blood samples for placental growth factor and soluble fms-like tyrosine kinase-1 testing was obtained, alongside clinical data, for use within the PREP-S model. Candidate variables were compared using standard methods (sensitivity, specificity, receiver operator curve areas). Estimated probability of early delivery from PREP-S was compared with actual event rates by calibration. SETTING The PEACOCK (Prognostic indicators of severe disEAse in women with late preterm pre-eClampsia tO guide deCision maKing on timing of delivery) study was a prospective cohort study, nested within the PHOENIX (Pre-eclampsia in HOspital: Early iNductIon or eXpectant management) trial. PARTICIPANTS Women between 34+ 0 and 36+ 6 weeks' gestation, with a diagnosis of pre-eclampsia, in whom a plasma (ethylenediaminetetraacetic acid) blood sample for placental growth factor testing was obtained, alongside clinical data for the assessment of variables in a prognostic model. MAIN OUTCOME MEASURES Clinically indicated need for delivery for pre-eclampsia within 7 days of assessment. Statistical analysis: both PREP-S and placental growth factor were assessed and compared using standard methods (sensitivity and specificity for placental growth factor thresholds of 100 pg/ml and < 12 pg/ml, and receiver operating characteristic areas for continuous measurements). The estimated probability of early delivery from PREP-S was compared with actual event rates for women with similar probabilities by calibration. Calibration using logistic regression was also used. RESULTS Between 27 April 2016 and 24 December 2018, 501 women were recruited to the study. Although placental growth factor testing had high sensitivity (97.9%) for delivery within 7 days, the negative predictive value was only 71.4% and the specificity was low (8.4%). The area under the curve for the clinical prediction model (PREP-S) and placental growth factor in this cohort in determining need for delivery within 7 days was 0.64 (standard error 0.03) and 0.60 (standard error 0.03), respectively, and 0.65 (standard error 0.03) in combination. LIMITATIONS A high proportion of women in this cohort already had low placental growth factor concentrations at the time of confirmed diagnosis, which reduced the ability of the biomarker to further predict adverse outcomes. CONCLUSIONS In this group of women with late preterm pre-eclampsia, placental growth factor measurement is not likely to add to the current clinical assessment to help plan care for late preterm pre-eclampsia regarding timing of delivery. Existing models developed in women with early-onset pre-eclampsia to predict complications cannot be used to predict clinically indicated need for delivery in women with late preterm pre-eclampsia. FUTURE WORK Further statistical modelling and subgroup analysis is being considered to assess if improved model performance in the whole cohort or a subgroup can be achieved. Addition of other biomarkers to the model may also be of use and will be explored. TRIAL REGISTRATION Current Controlled Trials ISRCTN01879376.

Abstract
Background: Preeclampsia (PE) is diagnosed after 20 weeks of gestation. This multisystem disorder affects 2-7% of pregnant women. PE is a serious complication of pregnancy and one of the main causes of maternal and neonatal mortality and morbidity in the world. The inadequate placentation process results in a change in anti-angiogenic factors levels, such as placental protein 13 (PP13) and soluble fms-like tyrosine kinase 1 (sFlt-1).
Objectives: To investigate the correlation between urinary PP13 and sFlt-1 in preeclamptic women in their third trimester of pregnancy.
Methods: A case-control study was carried out from August 2018 till January 2019. Urine samples were collected from pregnant women at Al-Elweyia Hospital, Al-Hakeem Hospital, and Al- Imamain Al-Kadhimain Medical City (in Baghdad, Iraq). The patients’ group include fifty women with PE in the third trimester (25 mild and 25 severe). Fifty healthy pregnant women (at their third trimester of pregnancy) were studied as a control group.
Results: The mean urinary PP13 levels were decreased in women with PE significantly (p≤ 0.05) (mild and severe) compared with healthy women (43.44±4.914 pg/ml, 33.34±1.863 pg/ml, and 51.84 ±2.60 pg/ml) respectively. Also, urinary sFlt-1 concentrations were decreased non-significantly (p> 0.05) in women with PE (mild and severe) compared with healthy women (5.71±0.414 ng/ml, 5.31±0.38 ng/ml and 6.01±0.282 ng/ml), respectively.
Conclusions: Urinary PP13 and sFlt-1 levels in the third trimester of pregnancy were significantly correlated with the severity of PE, and urinary levels of PP13 were found to be decreased significantly in patients with PE than in healthy pregnant women in the 3rd trimester of pregnancy.

Abstract
BACKGROUND As a serious pregnancy-specific condition, preeclampsia (PE) is a serious pregnancy-specific condition characterized by insufficient trophoblastic invasion and shallow placental implantation. Long noncoding RNA uc.187, which is transcribed from an ultra-conserved region is highly expressed in the placental tissue of patients with PE, is associated with abnormal trophoblast invasion. Therefore, we aimed to further characterize the relationship between uc.187 and PE through in vitro experimental studies to find new targets to treat PE. METHODS In this study, we constructed PE rat models induced by lipopolysaccharide, experimented with overexpressing uc.187 and performed experiments using HTR-8/SVneo cells. RESULTS We found uc.187 was elevated in the placenta of PE rats. By injecting pregnant rats with a lentivirus containing the lncRNA uc.187, we successfully triggered maternal hypertension along with a series of symptoms similar to PE in humans. In vitro experiments demonstrated that high levels of uc.187 lead to decreased trophoblast invasion. In addition, our results revealed that uc.187 had high expression in PE and fetal growth restricted cells, but low expression in placental site trophoblastic tumors compared with the control groups. Results of western blot and cell immunofluorescence indicated that the aberrant biological behavior of HTR-8/SVneo cells were related to the distribution of β-catenin in the cytoplasm and nucleus. CONCLUSIONS Taken together, our study revealed that uc.187 was negatively correlated to trophoblastic cell invasion, and overexpression of uc.187 could induce PE-like symptoms in a pregnant rat model by affecting the distribution of β-catenin in the cytoplasm and nucleus.

Urinary and Serum Angiogenic Markers in Women With Preexisting Diabetes During Pregnancy and Their Role in Preeclampsia Prediction. Diabetes Care 2020; 43:67-73. [PMID: 31601637 DOI: 10.2337/dc19-0967] [Citation(s) in RCA: 12] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/14/2019] [Accepted: 09/26/2019] [Indexed: 02/03/2023]
Abstract
OBJECTIVE To determine the correlation between urinary and serum placental growth factor (PlGF) and investigate the predictive value as pregnancy progresses of urinary PlGF compared with serum PlGF, soluble fms-like tyrosine kinase 1 (sFLT-1), and the sFLT-1-to-PlGF ratio for the outcome of preeclampsia in women with preexisting diabetes. RESEARCH DESIGN AND METHODS A multicenter prospective cohort study was conducted of 158 women with preexisting insulin-requiring diabetes (41 with type 1 and 117 with type 2). Urinary PlGF and serum PlGF, sFLT-1, and the sFLT-1-to-PlGF ratio were assessed four times (14, 24, 30, and 36 weeks' gestation), and the association with the outcome of preeclampsia was investigated. RESULTS A correlation between urinary and serum PlGF was demonstrated from 24 weeks' gestation onward (P < 0.001). At all time points, those who developed preeclampsia had lower serum PlGF levels (P < 0.05), and receiver operating characteristic curves demonstrated that serum PlGF in this cohort performed better than the serum sFLT-1-to-PlGF ratio as a predictive test for preeclampsia. Preconception HbA1c ≥6.5% (48 mmol/mol) was an important discriminative predictor for preeclampsia (P = 0.01). CONCLUSIONS This study prospectively describes the longitudinal changes in urinary PlGF alongside serum angiogenic markers throughout pregnancy in women with preexisting diabetes. We demonstrate correlation between urinary and serum PlGF and that in women with preexisting diabetes in pregnancy, serum PlGF is a better predictor of preeclampsia than the sFLT-1-to-PlGF ratio.

Abstract
OBJECTIVE To evaluate whether urinary levels of placental growth factor (PlGF) during pregnancy are associated with the subsequent development of composite adverse outcomes (preeclampsia, fetal growth restriction, placental abruption, perinatal death, maternal death) occurring at less than 34 weeks of gestation. METHODS This is a preplanned ancillary study of the Heparin-Preeclampsia trial, a randomized trial in pregnant women with a history of severe early-onset preeclampsia (less than 34 weeks of gestation). In the parent study, all women were treated with aspirin and then randomized to receive either low-molecular-weight (LMW) heparin or aspirin alone. For this substudy we measured urinary levels of PlGF and urinary creatinine at the following gestational windows: 10-13 6/7, 14-17 6/7, 18-21 6/7, 22-25 6/7, 26-29 6/7, 30-33 6/7, and 34-37 6/7 weeks of gestation. RESULTS Urine samples were available from 187 patients: LMW heparin plus aspirin (n=93) and aspirin alone (n=94). The two groups had comparable baseline characteristics and had similar adverse composite outcomes at less than 34 weeks of gestation (14/93 [15.1%] vs 11/94 [11.7%]; P=.50). There were no significant differences in urine PlGF levels in the patients who received LMW heparin plus aspirin compared with those who received aspirin alone. However, median [interquartile range] urinary PlGF/creatinine concentrations (pg/mg) measured at mid-pregnancy (22-26 weeks of gestation) were significantly lower among women who developed composite adverse outcome at less than 34 weeks of gestation (42.7 [32.4-80.8] vs 255.6 [118.7-391.8] P<.001) and significantly lower among women who developed preeclampsia at less than 34 weeks of gestation (42.7 [27.5-80.7] vs 244.6 [112.9-390.6] P<.001). For a fixed false-positive rate of 10% the sensitivity of urinary PlGF concentrations at mid-pregnancy was 75.2% (area under the curve 0.93) for the subsequent development of composite adverse outcomes. CONCLUSION Decreased urinary PlGF at mid-gestation (22-26 weeks of gestation) is associated with the subsequent development of preeclampsia-related adverse outcomes at less than 34 weeks of gestation.

Abstract
Objective To determine the association between levels of serum 25-hydroxyvitamin D (25[OH]D) and soluble fms-like tyrosine kinase 1 (sFlt-1) in patients with preeclampsia. Methods Clinical and demographic data were collected from patients with preeclampsia and healthy pregnant controls. Serum 25(OH)D and sFlt-1 levels were evaluated by enzyme-linked immunosorbent assay and their correlations were determined using Spearman’s rank correlation coefficient. Associations between serum 25(OH)D and sFlt-1 levels and disease severity and clinical parameters were evaluated. Results Significantly lower serum 25(OH)D and higher sFlt-1 levels were observed in patients with preeclampsia (n = 100) versus controls (n = 100), and 25(OH)D was inversely correlated with sFlt-1 in patients with preeclampsia. Serum 25(OH)D levels were reduced, while sFlt-1 concentration was increased in patients with severe versus mild preeclampsia. Serum 25(OH)D levels were reduced in late-onset versus early-onset severe preeclampsia. Patients with preeclampsia who had lower serum 25(OH)D or elevated sFlt-1 levels showed significantly higher blood pressure indexes versus those with higher 25(OH)D or lower sFlt-1. Conclusions Low serum 25(OH)D and high sFlt-1 may be candidate biomarkers for preeclampsia diagnosis and prognosis.

Abstract
Objective The aim of this study was to investigate the diagnostic efficacy of thrombelastography (TEG) in patients with preeclampsia. Methods One hundred and seventeen pregnant women were recruited from Department of Obstetrics and Gynecology of 1st affiliated Hospital of Fujian Medical University. Of the 117 patients, 59 were normal late gestation (control group), 32 were mild preeclampsia and other 26 cases were severe preeclampsia. All the patients were received thrombelastography (including: K time, Reaction time, Clot angel, MA value, CI value) and blood coagulation examination (including: PT, APTT, Fib, TT, D-dimer and AT-III). Results The R time, K time, Coagulation Index value and Clot Angle in preeclampsia group were significant different between control and preeclampsia groups with statistical difference (p<0.05). Moreover, the R and K time value in severe preeclampsia group were significant higher than those of control groups (p<0.05); however, the Coagulation Index value and Clot Angle in severe preeclampsia group were significant higher than those of mild preeclampsia group with statistical difference (p<0.05). Coagulation Index had the highest diagnostic sensitivity [87.93 (76.70-95.01) %] and specificity [83.83 (79.17-96.18)%] compared to other parameters with the AUC of 0.94 (0.90-0.98). The K time and the Coagulation Index had the highest diagnostic sensitivity (96.15%) and specificity (0.75%) respectively with the AUC of 0.68 and 0.75 respectively in differential diagnosis of severe preeclampsia from mild preeclampsia. However, there were no statistical difference in the aspects of platelet count and parameters relevant to coagulation test for the control, mild and sever preeclampsia groups(p>0.05). Conclusion TEG provides more accurate information in monitoring the blood coagulation of preeclampsia patients and can be used as a reliable marker for assessing the severity of preeclampsia.

Abstract
AIM To correlate plasma and urinary soluble fms-like tyrosine kinase 1 (sFlt-1) and placental growth factor (PIGF) in preeclampsia (PE) and fetal growth restriction (FGR) and assess the performance in detecting established disease. METHODS A cross-sectional case-control study recruited 26-40 weeks gestation pregnancies into four clinical groups: normal pregnancy, PE, PE + FGR, and FGR. enzyme-linked immunosorbent assay (ELISA) measurements of urinary and plasma sFlt-1 and PlGF levels were performed. Urinary levels of sFlt-1 and PIGF were normalized to creatinine. Spearman's rank correlation was used to assess the association between plasma and urinary levels of sFlt-1 and PIGF, and receiver operating characteristic graphs were used to quantify the performance of each individual marker and their ratios in predicting normal versus pathological pregnancies affected by preeclampsia and/or FGR. RESULTS There was a significant correlation between plasma PlGF and urinary PlGF (r = 0.718, P < 0.001) in all groups. In the pathological groups, plasma sFlt-1 and urinary sFlt-1 as well as plasma sFlt-1: PIGF ratio and urinary sFlt-1: PlGF ratio were higher, but plasma PIGF and urinary PlGF were lower when compared to normal pregnancy. Plasma PIGF and plasma sFlt-1: PlGF ratio was comparable in performance to urinary PlGF and urinary sFlt-1: PIGF ratio for the diagnosis of preeclampsia and/or FGR. CONCLUSION Urinary PIGF can be used as an alternative to circulating biomarkers in preeclampsia and FGR. Plasma sFlt-1, PlGF and sFlt-1: PlGF ratio as well as urinary PIGF and sFlt-1: PlGF ratio can be used to differentiate between normal pregnancy and pregnancies complicated by preeclampsia and FGR.

Abstract
PURPOSE OF REVIEW Preeclampsia (PE) is a hypertensive disorder exclusive for pregnancy. It affects women all over the world and poses a great threat to life, both for mother and child. No definitive treatment exists and placenta delivery comprises the only known cure for PE. One of the most severe complications observed in preeclamptic women is the occurrence of cardiovascular diseases (CVDs) later in life. RECENT FINDINGS Both PE and CVDs share some of their pathogenic pathways and gene variations. Thus far, a number of publications have examined those relationships; however, almost all of them focus only on common risk factors. The precise pathomechanism and genetic basis of PE and its associated cardiovascular complications remain unknown. Therefore, the aim of this review is to unify and clarify the current state of knowledge and provide direction for future studies, especially those regarding the genetic aspect.

Abstract
We investigated the effects of sildenafil citrate (SC) on podocyturia in N ω-nitro-L-arginine methyl ester hydrochloride (L-NAME) model of pre-eclampsia (PE). One hundred and twenty Sprague-Dawley rats (SDR) were divided into five groups like pregnant control (PC), early-onset PE (EOPE), late-onset PE(LOPE), early and late-onset PE with SC-treated groups [EOPE (SC); LOPE (SC)]. PE was induced in SDR by oral administration of L-NAME in drinking water for 4-8 days for EOPE and 8-14 day for LOPE. The blood pressure, urine volume and total urine protein were increased in EOPE and LOPE groups when compared to PC, and all the above parameters decreased in EOPE (SC) and LOPE (SC) groups when compared to EOPE and LOPE groups, respectively. The EOPE and LOPE groups showed an increase in urinary nephrin mRNA and podocin mRNA levels compared to PC group. Increases in serum and renal soluble fms-like tyrosine kinase-1 (sFlt-1) expression levels and decreases in renal vascular endothelial growth factor (VEGF) expression and serum placenta growth factor (PlGF) levels were observed in EOPE and LOPE groups when compared to PC group. In addition, decreases in serum and renal sFlt-1 expression levels and increases in renal VEGF expression and serum PlGF levels were observed in EOPE (SC) and LOPE (SC) groups when compared to EOPE and LOPE groups, respectively. The light microscopy showed that the renal tissue of L-NAME-treated rats had extensive glomerular damage, tubular damage and infiltration by mononuclear cells when compared to PC group. Therefore, SC ameliorated podocyturia through its effects on the antiangiogenic/angiogenic status in this animal model.
