Abstract
PURPOSE New-onset proteinuria, as a pivotal sign of representative renal lesions in preeclampsia, is still the most common diagnostic tool for this condition and has been proven to be related to a significantly abnormal sFlt-1/VEGF ratio in circulation. At the same time, blood pressure control plays a vital role in the occurrence and evolution of proteinuria. Therefore, it is particularly helpful to investigate their interval, not only for performing urinalysis for protein more accurately but also for evaluating blood pressure as well as the aggravation of illness, as the related research is limited. METHODS This retrospective study included 515 preeclampsia patients and 358 normotensive pregnant women who labored in the Second Hospital of Tianjin Medical University from January 2016 to January 2020. First, we described the onset circumstance of high blood pressure and proteinuria as well as the interval among the case group and the subgroups. Then, we determined whether there were significant differences in the basic information, laboratory test results, and newborns between the case and normal groups. Finally, multifactor ANOVA was used to determine the factors influencing the interval. RESULTS 1. The two most common complications in preeclampsia were proteinuria (88.35%) and placental dysfunction (5.05%). Moreover, 72.04% of preeclampsia cases were diagnosed by abnormal blood pressure together with new-onset proteinuria. 2. The average interval between high blood pressure and proteinuria was 22 gestational days (from 0 to 106 days), and this interval was not significantly different between mild and severe PE (26 days vs. 21 days, P > 0.05) but significantly differed between early-onset and late-onset PE (9 days vs. 28 days, P < 0.05). 3. The number of prenatal visits, serum creatinine in the early trimester, gestational time and diastolic blood pressure value when increased blood pressure was initially detected may influence the interval between the onset of increased blood pressure and proteinuria. CONCLUSION New-onset proteinuria was still the main parameter for identifying preeclampsia. The interval between increased blood pressure and proteinuria was probably related to the imbalance in the sFlt-1/VEGF ratio; therefore, we should pay attention to monitor proteinuria during the prenatal visits, especially for patients with a lower frequency of prenatal visits, higher serum creatinine in the early trimester, earlier onset and higher diastolic blood pressure at the initial onset of increased blood pressure.

Abstract
In the case of PIH, the history is the story of gradually developing awareness and the gradual formation of requisite knowledge. The development of the sphygmomanometer, or blood pressure cuff, in the late 1700s, provided the basis for modern systematic blood pressure reporting for Gravid patients. In the following years and over a few decades, the relationship between high blood pressure and these complications, such as preeclampsia and eclampsia, became clearer. The hypertensive disease was categorized by the American Committee on Maternal Welfare in 1952, which included PIH, chronic hypertension, and preeclampsia. Today, attention is being paid to the identification of such factors, the search for ways to enhance the treatment of diseases, methods for their diagnosis, and the enhancement of pregnancy outcomes. Pregnancy can cause high blood pressure in two of the following ways: preeclampsia and gestational hypertension. These conditions are both part of something called pregnancy-induced hypertension (PIH). In the world, most problems for moms and babies during pregnancy come from PIH. To help both mom and baby, we need to know a lot about what causes it, how to manage it, and how to watch the baby carefully. Aspects like immune responses, the environment, and genes all mix to cause PIH. They make the placenta not work right. When the cells that help the placenta grow don't do their job well, when blood vessels are stiff, when there's too much stress on the body, or when there's not a good balance of chemicals that help build blood vessels, things can get bad. Blood vessels all over the body squeeze tight, blood flow goes down, and blood pressure goes up. That can make a lot of organs stop working right and stop the baby from healthy growth. Various studies concluded that PIH severely limits the blood flow to the placenta and thus contributes to reduced fetal growth. It showed that compared to other hospitals, women who experience PIH are more likely to give birth early before the baby is ready, that is, before 37 weeks, and may cause further health complications to the baby. This normally makes the offspring have low birth weight and exposes them to many complications in infancy and the future in case they are born to mothers with PIH. In severe cases, PIH may lead to the death of the infant either by stillbirth or immediately after birth. The researchers have noted several predisposing factors to PIH, which include histories of elevated blood pressure, diabetes, being overweight or obese, and having a family history of PIH. Educating women about the presence of PIH and its causes can help them consult health facilities early, thus helping leaders in achieving better pregnancy results.

Abstract
Placental development is a tightly controlled event, in which cell expansion from the trophectoderm occurs in a spatiotemporal manner. Proper trophoblast differentiation is crucial to the vitality of this gestational organ. Obstructions to its development can lead to pregnancy complications, such as preeclampsia, fetal growth restriction, and preterm birth, posing severe health risks to both the mother and offspring. Currently, the only known treatment strategy for these complications is delivery, making it an important area of research. The aim of this review was to summarize the known information on the development and mechanistic regulation of trophoblast differentiation and highlight the similarities in these processes between the human and mouse placenta. Additionally, the known biomarkers for each cell type were compiled to aid in the analysis of sequencing technologies.

Abstract
Preeclampsia and other hypertensive disorders of pregnancy are major contributors to maternal morbidity and mortality worldwide. This group of disorders includes chronic hypertension, gestational hypertension, preeclampsia, preeclampsia superimposed on chronic hypertension, and eclampsia. The body undergoes important physiological changes during pregnancy to allow for normal placental and fetal development. Several mechanisms have been proposed that may lead to preeclampsia, including abnormal placentation and placental hypoxia, impaired angiogenesis, excessive pro-inflammatory response, immune system imbalance, abnormalities of cellular senescence, alterations in regulation and activity of angiotensin II, and oxidative stress, ultimately resulting in upregulation of multiple mediators of endothelial cell dysfunction leading to maternal disease. The clinical implications of preeclampsia are significant as there are important short-term and long-term health consequences for those affected. Preeclampsia leads to increased risk of preterm delivery and increased morbidity and mortality of both the developing fetus and mother. Preeclampsia also commonly leads to acute kidney injury, and women who experience preeclampsia or another hypertensive disorder of pregnancy are at increased lifetime risk of chronic kidney disease and cardiovascular disease. An understanding of normal pregnancy physiology and the pathophysiology of preeclampsia is essential to develop novel treatment approaches and manage patients with preeclampsia and hypertensive disorders of pregnancy. © 2023 American Physiological Society.

Abstract
OBJECTIVES To assess risk factors and incidence of diabetes complications in women with type 1 diabetes (T1D) based on parity. RESEARCH DESIGN/METHODS Data were collected from women (16-40 years old) in the T1D Exchange completing pregnancy/childbirth questionnaires during 2011-2013 and 2016-2018. Incidence of risk factors and diabetes complications were compared between women with a first pregnancy at/within 1-year of enrollment (n = 28) and never pregnant women by year 5 (n = 469). RESULTS There was a trend for lower HbA1c (adjusted p = .14) and higher rates of overweight/obesity, triglyceride/HDL > 2, log (triglyercide/HDL), and hypertension among parous women compared with nulliparous women. There were no significant differences in rates of advanced nephropathy, albuminuria or cardiovascular disease. CONCLUSIONS Four-5 years after delivery, parous women with T1D tended to have lower HbA1c levels despite higher body mass indices and more frequent adverse lipid profiles and hypertension compared with nulliparous women. Further studies based on these trends are warranted.

Abstract
Pregnancy is often considered to be a "cardiometabolic stress-test" and pregnancy complications including hypertensive disorders of pregnancy can be the first indicator of increased risk of future cardiovascular disease. Over the last two decades, more evidence on the association between hypertensive disorders of pregnancy and cardiovascular disease has become available. However, despite the importance of addressing existing racial and ethnic differences in the incidence of cardiovascular disease, most research on the role of hypertensive disorders of pregnancy is conducted in white majority populations. The fragmented knowledge prohibits evidence-based targeted prevention and intervention strategies in multi-ethnic populations and maintains the gap in health outcomes. In this review, we present an overview of the evidence on racial and ethnic differences in the occurrence of hypertensive disorders of pregnancy, as well as evidence on the association of hypertensive disorders of pregnancy with cardiovascular risk factors and cardiovascular disease across different non-White populations, aiming to advance equity in medicine.

Abstract
About 5-10% of pregnancies are complicated by one of the hypertensive disorders of pregnancy. The women who experience these disorders have a greater risk of having or developing kidney diseases than women with normotensive pregnancies. While international guidelines do not provide clear indications for a nephrology work-up after pregnancy, this is increasingly being advised by nephrology societies. The definitions of the hypertensive disorders of pregnancy have changed greatly in recent years. The objective of this short review is to gather and comment upon the main definitions of the hypertensive disorders of pregnancy as a support for nephrologists, who are increasingly involved in the short- and long-term management of women with these disorders.

Ann Med Surg (Lond) 2022; 78:103818. [PMID: 35734723 PMCID: PMC9206927 DOI: 10.1016/j.amsu.2022.103818] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/07/2022] [Revised: 05/12/2022] [Accepted: 05/14/2022] [Indexed: 11/25/2022] Open
Abstract
Introduction Preeclampsia (PE) is an important complication of pregnancy that can lead to chronic kidney disease. Soluble fms-like tyrosine kinase-1 (sFlt-1), placental growth factor (PlGF), the sFlt-1/PlGF ratio and endoglin are biomarkers for the differential diagnosis of PE and other diseases. We aimed to explore the correlation of these biomarkers with long-term renal function, blood pressure and the urine albumin/creatinine ratio (UACR) in PE patients. Methods 34 patients with PE were enrolled. Blood samples for sFlt-1, PlGF, endoglin and the urine albumin/creatinine ratio (UACR) were collected at the time of PE diagnosis (at 35–40 weeks’ gestational age (GA) (87.50% of cases). After delivery, the patients were followed up at three months and one year to assess blood pressure, renal function and the UACR. Results Thirty-four PE patients were included, and 17 completed the study. The estimated glomerular filtration rate (eGFR) decreased significantly at three months and one year after follow-up (128.20 ± 10.34 to 120.75 ± 10.166 ml/min/1.73 m2 (p = 0.001) at three months and 126.71 ± 9.948 to 114.29 ± 11.274 ml/min/1.73 m2 (p < 0.001) at one year). The endoglin level correlated significantly with the eGFR level during PE, but there was no correlation of any biomarker with eGFR, blood pressure, or the UACR at one year. Conclusion Women with PE have a reduction of eGFR at three months and one year after the diagnosis of PE. Only endoglin is correlated with eGFR antepartum; however, it is not correlated with long-term renal function, blood pressure or the UACR. Preeclampsia has been suggested to increase the risk of kidney problems. The soluble endoglin level and sFlt-1:PlGF ratio can predict early and late-onset preeclampsia. Analysis of angiogenic factors may be associated with long term renal function.

Abstract
BACKGROUND Maternal morbidity and mortality are related to prepregnancy hypertensive disease and hypertensive disorders of pregnancy (HDP) including preeclampsia (41.1% of HDP), eclampsia (1.3% of HDP), and gestational hypertension (39.9% of HDP). Less information is available on the risk of maternal kidney disease and potential racial/ethnic differences following a hypertensive condition during pregnancy. Our objective was to examine the relationships between HDP and prepregnancy hypertension with maternal incident kidney disease subsequent to delivery (up to 3, 5, and 14 years) with consideration of racial/ethnic differences. METHODS In a retrospective cohort study, 391 838 women 12 to 49 years of age had a live birth in South Carolina between 2004 and 2016; 35.1% non-Hispanic Black (NHB) and 64.9% non-Hispanic White (NHW). Hospitalization, emergency department, and birth certificate data defined prepregnancy hypertension and HDP. Hospitalization and death certificate data identified incident kidney disease. RESULTS 317 006 (80.8%) women experienced neither condition, 1473 (0.4%) had prepregnancy hypertension, 64 050 (16.3%) had HDP, and 9662 (2.5%) had both conditions (prepregnancy hypertension with superimposed HDP, ie, preeclampsia). Five years after delivery, incident kidney disease risk was increased for NHB and NHW women with HDP (NHB: hazard ratio, 2.30 [95% CI, 1.94-2.73]; NHW: hazard ratio, 1.97 [95% CI, 1.64-2.37]) and with both conditions (NHB: hazard ratio, 3.88 [95% CI, 3.05-4.93]; NHW: hazard ratio, 1.86 [95% CI, 1.20-2.87]) compared with counterparts with neither condition after adjustment (P value for race/ethnicity interaction=0.003). CONCLUSIONS Increased kidney disease risk 5 years after delivery was observed for women with HDP and with both compared with neither condition, with associated risk higher in NHB than NHW women.

Abstract
OBJECTIVE To evaluate the relationship between hypertensive diseases in pregnancy and kidney function later in life. METHODS We evaluated measured glomerular filtration rate (mGFR) using iothalamate urinary clearance in 725 women of the Genetic Epidemiology Network of Arteriopathy (GENOA) study. Women were classified by self-report as nulliparous (n=62), a history of normotensive pregnancies (n=544), a history of hypertensive pregnancies (n=102), or a history of pre-eclampsia (n=17). We compared adjusted associations among these four groups with mGFR using generalized estimating equations to account for familial clustering. Chronic kidney disease (CKD) was defined as mGFR of less than 60 mL/min per 1.73 m2 or urinary albumin-creatinine ratio (UACR) greater than or equal to 30 mg/g. RESULTS Among women with kidney function measurements (mean age, 59±9 years, 52.9% African American), those with a history of hypertensive pregnancy had lower mGFR (-4.66 ml/min per 1.73 m2; 95% CI, -9.12 to -0.20) compared with women with a history of normotensive pregnancies. Compared with women with a history of normotensive pregnancies, women with a history of hypertensive pregnancy also had higher odds of mGFR less than 60 ml/min per 1.73 m2 (odds ratio, 2.09; 95% CI, 1.21 to 3.60). Additionally, women with a history of hypertensive pregnancy had greater odds for chronic kidney disease (odds ratio, 4.89; 95% CI, 1.55 to 15.44), after adjusting for age, race, education, smoking history, hypertension, body mass index, and diabetes. CONCLUSION A history of hypertension in pregnancy is an important prognostic risk factor for kidney disease. To our knowledge, this is the first and largest investigation showing the association between hypertensive diseases in pregnancy and subsequent kidney disease using mGFR in a large biracial cohort.

[PMID: 36035364 PMCID: PMC9413555 DOI: 10.7150/ijms.72926] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/16/2022] [Accepted: 08/01/2022] [Indexed: 11/10/2022] Open
Abstract
Introduction: To evaluate patterns of change in the urine protein-to-creatinine ratios (uPCRs) during labor at term between normal and women with pregnancy-induced hypertension (PIH). Methods: This is an observational study in tertiary referral hospital, recruiting 269 women at term delivery in Taiwan from April 19, 2019 to April 18, 2021. uPCRs in four phases (latent, active, recovery and early postpartum) and related clinical data at delivery were collected. Multivariate analyses with a linear regression model were performed to analyze continuous variables after adjusting for clinical data between two groups. Results: Based on exclusion criteria, 68 normal and 24 pregnant women with PIH were included. There were no differences in the uPCR or the proportion cases of uPCRs ≥ 300 mg/g between normal and PIH group in the four phases. There was a statistically significant tendency for the proportion of uPCRs ≥ 300 mg/g to increase from the latent to the early postpartum phase in both groups. The proportion of uPCRs ≥ 300 mg/g significantly increased from the active to the recovery phase and then declined from the recovery to the early postpartum phase in the normal group. Thus no differences in uPCRs cases change between any two phases in women with PIH, except the duration above stated. Conclusion: This is the first study to demonstrate that uPCRs data are not different between normal pregnant and PIH groups during the course of labor, but it did show different dynamic change patterns throughout the labor phases.

Bridging the Postpartum Gap: A Randomized Controlled Trial to Improve Postpartum Visit Attendance Among Low-Income Women with Limited English Proficiency. WOMEN'S HEALTH REPORTS 2021; 2:381-388. [PMID: 34671758 PMCID: PMC8524728 DOI: 10.1089/whr.2020.0123] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Accepted: 07/14/2021] [Indexed: 11/12/2022]
Abstract
Background: Rates of postpartum visit attendance are low among all women, and particularly for low-income women. Experts in obstetrics, women's health, and health disparities are calling for novel, holistic approaches to postpartum care to better meet the needs of women and that respond to existing health care disparities. Materials and Methods: We conducted a single-site parallel-arm randomized controlled trial to determine the feasibility and effect of a co-located, co-timed 4-6 weeks postpartum obstetrics visit and well-newborn pediatric visit (i.e., "mommy-baby visit") compared with an enhanced usual postpartum visit, that is, staff scheduled the postpartum visit for the patient before hospital discharge. Results: One hundred sixteen women, of whom 76.7% (n = 89) were Latina immigrants, were enrolled postdelivery and randomized to a mommy-baby visit (n = 58, 49.5%) or to enhanced usual care (n = 58, 50.4%). Almost all study participants attended their postpartum visit (n = 109, 94.0%). There was no significant difference in postpartum visit attendance rate by randomization assignment (91.4% of mommy-baby vs. 96.6% of enhanced usual care participants). Study participants, mommy-baby intervention and enhanced usual care arms combined, were significantly more likely to attend the postpartum visit than historical controls (94.0% vs. 69.7%, respectively, p < 0.001). Conclusions: In a randomized controlled trial, we showed postpartum visit attendance rates were high for participants in both the mommy-baby and enhanced usual care arms. Postpartum visit scheduling assistance was provided to all participants and may have increased postpartum visit attendance and thereby attenuated the effect of the intervention. It is encouraging that a low-cost, low-tech, low-touch intervention, that is, postpartum appointment scheduling before hospital discharge, could increase postpartum visit attendance.

Abstract
OBJECTIVES We aimed to quantitatively synthesize the association between maternal exposure to particulate matter (PM; including PM <2.5 μm and PM <10 μm) and hypertensive disorders in pregnancy (HDP; including gestational hypertension [GH] and pre-eclampsia) and to explore the influence of certain factors on the outcome. STUDY DESIGN Meta-analysis was used to quantitatively synthesize the results of similar independent studies. METHODS Original documents were identified by searching six electronic bibliographic databases from their inceptions to August 17, 2021. Then we performed meta-analysis to combine the effect estimates if at least three estimates reported the same exposure and outcome and used stratified analysis to evaluate the impact of exposure assessment method, data source, and study area on heterogeneity. In addition, we used the 95% prediction interval to evaluate the potential effects of exposure in random effects meta-analysis. RESULTS The overall meta-analysis showed that the risk of HDP was significantly associated with per 5 μg/m3 increase in PM2.5 exposure during T1 and PM10 exposure during T, with odds ratios [ORs] 1.06 (95% confidence interval [CI]: 1.01-1.12) and 1.04 (95% CI: 1.02-1.07), respectively. The results also showed that PM2.5 exposure during T1 and T2 and PM10 exposure during T1 increased the incidence of GH; the summary ORs were 1.11 (95% CI: 1.01-1.23), 1.16 (95% CI: 1.05-1.29), and 1.04 (95% CI: 1.02-1.07), respectively. Subgroup analyses showed that the pooled effects were generally significant or more apparent in studies using models to assess exposure, studies whose data derived from birth registers, and studies in Europe. CONCLUSIONS This meta-analysis showed that PM exposure was associated with increased HDP risks, and the association varied by study area, data source, and exposure assessment method. With the continuous improvement of research design and exposure assessment, future research may find higher risks.

Abstract
RATIONALE & OBJECTIVE Even though studies have demonstrated a relationship between hypertensive disorders of pregnancy (HDPs) and chronic kidney disease, there are limited data on the risk of acute kidney injury (AKI) following HDPs. We examined the risk of AKI following the occurrence of HDPs. STUDY DESIGN Retrospective population-based cohort study. SETTING & PARTICIPANTS Pregnant women in Ontario, Canada, aged 14-50 years, who delivered at ≥20 weeks' gestation between April 1, 2002, and March 31, 2015. EXPOSURE Preeclampsia, gestational hypertension, or neither. OUTCOMES The primary outcome was AKI with receipt of dialysis (AKI-D) ≥90 days after delivery. The main secondary outcome was AKI based on a hospitalization with a diagnostic code for AKI ≥90 days after delivery. ANALYTICAL APPROACH Time-dependent Cox proportional and cause-specific hazards models were used to evaluate the relationship between HDP and outcomes of interest. Models were adjusted for baseline and time-varying covariates. RESULTS Our cohort comprised 1,142,656 women and 1,826,235 deliveries, of which 1.7% were associated with gestational hypertension and 4.4% with preeclampsia. After a mean follow-up of 6.7 years, there were 322 episodes of AKI-D (0.41 per 10,000 person-years) and 1,598 episodes of AKI based on diagnostic codes (2.04 per 10,000 person-years). After adjustment, neither preeclampsia nor gestational hypertension was associated with AKI-D. Preeclampsia was associated with AKI (HR, 1.22 [95% CI, 1.03-1.45]), but gestational hypertension was not. LIMITATIONS Retrospective design and possible unmeasured confounding. Cases of HDPs and AKI may have been undetected. CONCLUSIONS Preeclampsia was a risk factor for AKI occurring ≥90 days after delivery. Our findings suggest the potential importance of obtaining a pregnancy history as part of a comprehensive risk profile for acute kidney disease and suggest that women with a history of HDP may benefit from monitoring of kidney function.

Abstract
Purpose Hypertensive disorders of pregnancy are still a leading cause of maternal and neonatal morbidity and mortality worldwide. Women with a history of preeclampsia have an increased risk for future cardiovascular and cerebrovascular disease, renal disease as well as diabetes mellitus. There is little knowledge on postpartum risk management. The aim of this study was to assess follow-up care for patients after pre-eclampsia or HELLP syndrome. Methods This questionnaire-based cross-sectional study aimed to evaluate the current recommendations of obstetricians in Austria regarding follow-up care, long-term risk counselling and risk of recurrence in future pregnancies after preeclampsia or HELLP syndrome. Data were collected using a survey, based on recommendations given by three substantial guidelines on hypertensive disorders of pregnancy, which was distributed via e-mail to 69 public obstetric departments in Austria. Each obstetric department was required to answer one questionnaire per local protocol. Results Our results revealed that of the 48 participating hospitals most obstetricians are aware of the importance of follow-up care for women after a pregnancy complicated by preeclampsia. Our data show that most physicians counselled patients about the future cardiovascular health risks associated with preeclampsia or HELLP syndrome (79.2%). Most obstetricians recommended lifestyle modification (77.1%) and continued blood pressure measurements (97.9%). All centers stated to counsel about the risk of recurrence (100%). However, counselling regarding follow-up care to exclude kidney damage (37.5%) and underlying diseases like thrombophilia (39.6%) were less prioritized. Conclusions We were able to show that counselling concerning the risk of long-term cardiovascular disease and risk of recurrence after a pregnancy complicated by preeclampsia or HELLP syndrome has been established in obstetric departments in public hospitals. Regarding the evaluation of underlying chronic diseases such as thrombophilia or renal disease, as well as counselling on the future risk of renal disease is still improvable according to our data. Further evaluation of follow-up care after hypertensive disorders of pregnancy in the outpatient and private sector and implementation of structured guidelines for follow-up, as well as screening for cardiovascular disease are necessary to ensure adequate risk management and to provide opportunities for prevention.

Abstract
BACKGROUND Worldwide, hypertensive disorders in pregnancy (HDPs) complicate between 5 and 10% of pregnancies. Sub-Saharan Africa (SSA) is disproportionately affected by a high burden of HDPs and chronic kidney disease (CKD). Despite mounting evidence associating HDPs with the development of CKD, data from SSA are scarce. METHODS Women with HDPs (n = 410) and normotensive women (n = 78) were recruited at delivery and prospectively followed-up at 9 weeks, 6 months and 1 year postpartum. Serum creatinine was measured at all time points and the estimated glomerular filtration rates (eGFR) using CKD-Epidemiology equation determined. CKD was defined as decreased eGFR< 60 mL/min/1.73m2 lasting for ≥ 3 months. Prevalence of CKD at 6 months and 1 year after delivery was estimated. Logistic regression analyses were conducted to evaluate risk factors for CKD at 6 months and 1 year postpartum. RESULTS Within 24 h of delivery, 9 weeks, and 6 months postpartum, women with HDPs were more likely to have a decreased eGFR compared to normotensive women (12, 5.7, 4.3% versus 0, 2 and 2.4%, respectively). The prevalence of CKD in HDPs at 6 months and 1 year postpartum was 6.1 and 7.6%, respectively, as opposed to zero prevalence in the normotensive women for the corresponding periods. Proportions of decreased eGFR varied with HDP sub-types and intervening postpartum time since delivery, with pre-eclampsia/eclampsia showing higher prevalence than chronic and gestational hypertension. Only maternal age was independently shown to be a risk factor for decreased eGFR at 6 months postpartum (aOR = 1.18/year; 95%CI 1.04-1.34). CONCLUSION Prior HDP was associated with risk of future CKD, with prior HDPs being more likely to experience evidence of CKD over periods of postpartum follow-up. Routine screening of women following HDP-complicated pregnancies should be part of a postpartum monitoring program to identify women at higher risk. Future research should report on both the eGFR and total urinary albumin excretion to enable detection of women at risk of future deterioration of renal function.

An observational claims data analysis on the risk of maternal chronic kidney disease after preterm delivery and preeclampsia. Sci Rep 2021; 11:12596.

Abstract
Women with complications of pregnancy such as preeclampsia and preterm birth are at risk for adverse long-term outcomes, including an increased future risk of chronic kidney disease (CKD) and end-stage kidney disease (ESKD). This observational cohort study aimed to examine the risk of CKD after preterm delivery and preeclampsia in a large obstetric cohort in Germany, taking into account preexisting comorbidities, potential confounders, and the severity of CKD. Statutory claims data of the AOK Baden-Wuerttemberg were used to identify women with singleton live births between 2010 and 2017. Women with preexisting conditions including CKD, ESKD, and kidney replacement therapy (KRT) were excluded. Preterm delivery (< 37 gestational weeks) was the main exposure of interest; preeclampsia was investigated as secondary exposure. The main outcome was a newly recorded diagnosis of CKD in the claims database. Data were analyzed using Cox proportional hazard regression models. The time-dependent occurrence of CKD was analyzed for four strata, i.e., births with (i) neither an exposure of preterm delivery nor an exposure of preeclampsia, (ii) no exposure of preterm delivery but exposure of at least one preeclampsia, (iii) an exposure of at least one preterm delivery but no exposure of preeclampsia, or (iv) joint exposure of preterm delivery and preeclampsia. Risk stratification also included different CKD stages. Adjustments were made for confounding factors, such as maternal age, diabetes, obesity, and dyslipidemia. The cohort consisted of 193,152 women with 257,481 singleton live births. Mean observation time was 5.44 years. In total, there were 16,948 preterm deliveries (6.58%) and 14,448 births with at least one prior diagnosis of preeclampsia (5.61%). With a mean age of 30.51 years, 1,821 women developed any form of CKD. Compared to women with no risk exposure, women with a history of at least one preterm delivery (HR = 1.789) and women with a history of at least one preeclampsia (HR = 1.784) had an increased risk for any subsequent CKD. The highest risk for CKD was found for women with a joint exposure of preterm delivery and preeclampsia (HR = 5.227). These effects were the same in magnitude only for the outcome of mild to moderate CKD, but strongly increased for the outcome of severe CKD (HR = 11.90). Preterm delivery and preeclampsia were identified as independent risk factors for all CKD stages. A joint exposure or preterm birth and preeclampsia was associated with an excessive maternal risk burden for CKD in the first decade after pregnancy. Since consequent follow-up policies have not been defined yet, these results will help guide long-term surveillance for early detection and prevention of kidney disease, especially for women affected by both conditions.

Abstract
OBJECTIVE To assess the association between hypertensive disorders of pregnancy and adverse events after pregnancy, including chronic kidney disease and major adverse cardiovascular events (cerebrovascular accident, coronary artery disease, or death). METHODS A nationwide, population-based cohort study was conducted analyzing women with hypertensive disorders of pregnancy identified from Taiwan National Health Insurance Research Database from 2004 to 2015. Hypertensive disorders of pregnancy were identified using the International Classification of Diseases, Ninth Revision, Clinical Modification codes. The study cohort was comprised of women aged 20-40 years diagnosed with hypertensive disorders of pregnancy from 2006 to 2013. The comparison group comprised of four randomly selected women without hypertensive disorders of pregnancy, matched for age and index date for each woman with hypertensive disorders of pregnancy. All the women were followed from the date of cohort entry until they developed chronic kidney disease or major adverse cardiovascular events or until the end of 2015, whichever occurred first. A Cox proportional hazard model was used to estimate the risk of chronic kidney disease and major adverse cardiovascular events. RESULTS We identified 29,852 women with a diagnosis of hypertensive disorders of pregnancy and 119,408 matched women without hypertensive disorders of pregnancy who fit the inclusion criteria. The crude hazard ratios (HRs) were 5.22 (95% CI 4.67-5.83) and 2.26 (95% CI 1.99-2.57) for chronic kidney disease and major adverse cardiovascular events. After adjusting for potential confounders, hypertensive disorders of pregnancy was associated with a higher risk of chronic kidney disease (adjusted HR, 4.26; 95% CI 3.80-4.78), and major adverse cardiovascular events (adjusted HR, 2.15; 95% CI 1.89-2.45). CONCLUSION This population-based cohort study indicated that women with hypertensive disorders of pregnancy are at a higher risk of chronic kidney disease and major adverse cardiovascular events than women without hypertensive disorders of pregnancy. Further studies are required to clarify the nature of these associations and to improve public health interventions.

[PMID: 33594802 PMCID: PMC8189207 DOI: 10.1111/mcn.13157] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/18/2020] [Revised: 01/21/2021] [Accepted: 01/24/2021] [Indexed: 11/27/2022]
Abstract
In this secondary analysis of data from a double‐blind randomized controlled trial (clinicaltrials.gov identifier: NCT00133744) of micronutrient supplementation (multiple micronutrients [MMN], iron–folic acid [IFA] and folic acid [FA] alone), we examined the potential modifying effect of gestational age at enrolment on the association of antenatal supplementation and pregnancy‐induced hypertension (PIH). We included 18,775 nulliparous pregnant women with mild or no anaemia who were enrolled at 20 weeks of gestation or earlier from five counties of northern China. Women were randomly assigned to receive daily FA, IFA or MMN from enrolment until delivery. We used logistic regression to evaluate the association between PIH and timing of micronutrient supplementation. The incidence of PIH was statistically significantly lower among women who began MMN supplementation before 12 gestational weeks compared with women who began MMN supplementation at 12 weeks or later (RR = 0.74, 95% CI: 0.60–0.91). A similar protective effect was observed for both early‐onset (<28 weeks, RR 0.45, 0.21–0.96) and late‐onset of PIH (≥28 weeks, RR 0.77, 0.63–0.96). No statistically significant association was observed between PIH occurrence and timing of supplementation for FA or IFA. Maternal MMN supplementation and antenatal enrolment during the first trimester of pregnancy appeared to be of importance in preventing both early‐ and late‐onset of PIH.

Effect of preeclampsia and its severity on maternal serum NGAL and KIM-1 levels during pregnancy and the post-pregnancy period. Eur J Obstet Gynecol Reprod Biol 2020; 256:246-251. [PMID: 33248380 DOI: 10.1016/j.ejogrb.2020.11.040] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/04/2020] [Revised: 11/07/2020] [Accepted: 11/12/2020] [Indexed: 11/21/2022]
Abstract
OBJECTIVE The purpose of this trial was to appraise the effects of preeclampsia and its intensity on maternal serum neutrophil gelatinase-associated lipocalin (NGAL) and kidney injury molecule-1 (KIM-1) levels during pregnancy and the post-pregnancy period. STUDY DESIGN Firstly pregnant participants (n = 156) were separated into three groups, as control, mild, and severe preeclampsia. Secondly women in post-pregnancy period (n = 368) were separated into three groups according to history of pregnancy, as healthy control, mild, and severe preeclampsia. These women were identified through the hospital data system and contacted by telephone to participate in the study. RESULTS Our study comprised 147 patients, 77 of whom were pregnant and 70 of whom were in their post-pregnancy period after the exclusion criteria had been applied. In terms of maternal serum NGAL levels, there is a significant increase in the severe preeclampsia group compared with that in the mild preeclampsia and normal pregnancy groups (p < 0.001). During the post-pregnancy period, the maternal serum NGAL levels were found significantly higher in the severe preeclampsia group than in the mild preeclampsia group and non-hypertension control group (p < 0.001). Maternal serum KIM-1 levels were found as significantly higher in the severe and mild preeclampsia groups than in the non-hypertension pregnancy group (p = 0.004). During the post-pregnancy period, maternal serum KIM-1 levels were found as similar among all post pregnant groups (p = 0.792). CONCLUSIONS Our results indicated that as the severity of preeclampsia increases, kidney damage as assessed using NGAL levels continues for a long period of time, even during the post-pregnancy period.

Abstract
Preeclampsia is a multisystem progressive disorder of pregnancy that can be potentially catastrophic for the mother and the fetus. It involves complex perturbations of the kidney and systemic physiology, along with long-term effects on vascular and kidney health. Thus, the nephrologist plays a key role in the peripartum and long-term management of preeclampsia. Recent translational research has improved our understanding of its pathophysiology, and there is hope for novel therapies. In this review, we discuss the evolution of diagnostic criteria and dilemmas in the diagnosis of hypertensive disorders in pregnancy. We summarize the advances in the pathogenesis and prediction of preeclampsia. We describe the management and prevention of preeclampsia focusing specially on the forthcoming strategies from the nephrologist's perspective. We address the evidence regarding long-term outcomes for the mother and the child. We end with exploring areas warranting future research.

Abstract
PURPOSE OF REVIEW Preeclampsia and chronic kidney disease have a complex, bidirectional relationship. Women with kidney disease, with even mild reductions in glomerular filtrate rate, have an increased risk of developing preeclampsia. Preeclampsia, in turn, has been implicated in the subsequent development of albuminuria, chronic kidney disease, and end-stage kidney disease. We will discuss observational evidence and mechanisms linking the two disease processes. RECENT FINDINGS Preeclampsia is characterized by an imbalance in angiogenic factors that causes systemic endothelial dysfunction. Chronic kidney disease may predispose to the development of preeclampsia due to comorbid conditions, such as hypertension, but is also associated with impaired glycocalyx integrity and alterations in the complement and renin-angiotensin-aldosterone systems. Preeclampsia may lead to kidney disease by causing acute kidney injury, endothelial damage, and podocyte loss. Preeclampsia may be an important sex-specific risk factor for chronic kidney disease. Understanding how chronic kidney disease increases the risk of preeclampsia from a mechanistic standpoint may open the door to future biomarkers and therapeutics for all women.

Hypertensive disorders of pregnancy and the risk of chronic kidney disease: A Swedish registry-based cohort study. PLoS Med 2020; 17:e1003255. [PMID: 32797043 PMCID: PMC7428061 DOI: 10.1371/journal.pmed.1003255] [Citation(s) in RCA: 31] [Impact Index Per Article: 7.8] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/02/2020] [Accepted: 07/15/2020] [Indexed: 12/25/2022] Open
Abstract
BACKGROUND Hypertensive disorders of pregnancy (HDP) (preeclampsia, gestational hypertension) are associated with an increased risk of end-stage kidney disease (ESKD). Evidence for associations between HDP and chronic kidney disease (CKD) is more limited and inconsistent. The underlying causes of CKD are wide-ranging, and HDP may have differential associations with various aetiologies of CKD. We aimed to measure associations between HDP and maternal CKD in women who have had at least one live birth and to identify whether the risk differs by CKD aetiology. METHODS AND FINDINGS Using data from the Swedish Medical Birth Register (MBR), singleton live births from 1973 to 2012 were identified and linked to data from the Swedish Renal Register (SRR) and National Patient Register (NPR; up to 2013). Preeclampsia was the main exposure of interest and was treated as a time-dependent variable. Gestational hypertension was also investigated as a secondary exposure. The primary outcome was maternal CKD, and this was classified into 5 subtypes: hypertensive, diabetic, glomerular/proteinuric, tubulointerstitial, and other/nonspecific CKD. Cox proportional hazard regression models were used, adjusting for maternal age, country of origin, education level, antenatal BMI, smoking during pregnancy, gestational diabetes, and parity. Women with pre-pregnancy comorbidities were excluded. The final sample consisted of 1,924,409 women who had 3,726,554 singleton live births. The mean (±SD) age of women at first delivery was 27.0 (±5.1) years. Median follow-up was 20.7 (interquartile range [IQR] 9.9-30.0) years. A total of 90,917 women (4.7%) were diagnosed with preeclampsia, 43,964 (2.3%) had gestational hypertension, and 18,477 (0.9%) developed CKD. Preeclampsia was associated with a higher risk of developing CKD during follow-up (adjusted hazard ratio [aHR] 1.92, 95% CI 1.83-2.03, p < 0.001). This risk differed by CKD subtype and was higher for hypertensive CKD (aHR 3.72, 95% CI 3.05-4.53, p < 0.001), diabetic CKD (aHR 3.94, 95% CI 3.38-4.60, p < 0.001), and glomerular/proteinuric CKD (aHR 2.06, 95% CI 1.88-2.26, p < 0.001). More modest associations were observed between preeclampsia and tubulointerstitial CKD (aHR 1.44, 95% CI 1.24-1.68, p < 0.001) or other/nonspecific CKD (aHR 1.51, 95% CI 1.38-1.65, p < 0.001). The risk of CKD was increased after preterm preeclampsia, recurrent preeclampsia, or preeclampsia complicated by pre-pregnancy obesity. Women who had gestational hypertension also had increased risk of developing CKD (aHR 1.49, 95% CI 1.38-1.61, p < 0.001). This association was strongest for hypertensive CKD (aHR 3.13, 95% CI 2.47-3.97, p < 0.001). Limitations of the study are the possibility that cases of CKD were underdiagnosed in the national registers, and some women may have been too young to have developed symptomatic CKD despite the long follow-up time. Underreporting of postpartum hypertension is also possible. CONCLUSIONS In this study, we found that HDP are associated with increased risk of maternal CKD, particularly hypertensive or diabetic forms of CKD. The risk is higher after preterm preeclampsia, recurrent preeclampsia, or preeclampsia complicated by pre-pregnancy obesity. Women who experience HDP may benefit from future systematic renal monitoring.

Abstract
OBJECTIVES To assess whether there is a risk of kidney disease during the postpartum period of women who had preeclampsia (PE). STUDY DESIGN Observational trials were searched in the PubMed, Science Direct, Clinical trials, Cochrane, LILACS and Web of Science databases. The data extracted from the studies were systematized, and the risk of bias was evaluated for each of them. Meta-analyses were performed with studies that evaluated chronic kidney disease (CKD) and end-stage renal disease (ESRD), pooling the natural logarithms of the adjusted risk measures and the confidence intervals of each study in a random effects model. RESULTS Of the 4149 studies evaluated, 35 articles were included in the review, of which 3 of the CKD and 6 of the ESRD presented the necessary outcomes to compose the meta-analysis. A formal registration protocol was included in the PROSPERO database (number: CRD42019111821). There was a statistically significant difference between the development of CKD (hazard ratio (HR): 1.82, confidence interval to 95% (95% CI): 1.27-2.62, P < 0.01) and ESRD (HR: 3.01, confidence interval to 95% (95% CI): 1.92-4.70, P < 0.01) in postpartum women affected by PE. CONCLUSIONS PE was considered a risk factor for the onset of CKD and ESRD in the postpartum period. Thus, more research is needed to clarify the underlying mechanisms of this association, and to assist in determining the most appropriate and effective clinical conduct to prevent and/or treat such complications.

Abstract
Purpose of review: To review an international guideline on the evaluation and care of living
kidney donors and provide a commentary on the applicability of the
recommendations to the Canadian donor population. Sources of information: We reviewed the 2017 Kidney Disease: Improving Global Outcomes (KDIGO)
Clinical Practice Guideline on the Evaluation and Care of Living Kidney
Donors and compared this guideline to the Canadian 2014 Kidney Paired
Donation (KPD) Protocol for Participating Donors. Methods: A working group was formed consisting of members from the Canadian Society of
Transplantation and the Canadian Society of Nephrology. Members were
selected to have representation from across Canada and in various
subspecialties related to living kidney donation, including nephrology,
surgery, transplantation, pediatrics, and ethics. Key findings: Many of the KDIGO Guideline recommendations align with the KPD Protocol
recommendations. Canadian researchers have contributed to much of the
evidence on donor evaluation and outcomes used to support the KDIGO
Guideline recommendations. Limitations: Certain outcomes and risk assessment tools have yet to be validated in the
Canadian donor population. Implications: Living kidney donors should be counseled on the risks of postdonation
outcomes given recent evidence, understanding the limitations of the
literature with respect to its generalizability to the Canadian donor
population.

Abstract
Preeclampsia is defined as new-onset hypertension after the 20th wk of gestation along with evidence of maternal organ failure. Rates of preeclampsia have steadily increased over the past 30 yr, affecting ∼4% of pregnancies in the United States and causing a high economic burden (22, 69). The pathogenesis is multifactorial, with acknowledged contributions by placental, vascular, renal, and immunological dysfunction. Treatment is limited, commonly using symptomatic management and/or early delivery of the fetus (6). Along with significant peripartum morbidity and mortality, current research continues to demonstrate that the consequences of preeclampsia extend far beyond preterm delivery. It has lasting effects for both mother and child, resulting in increased susceptibility to hypertension and chronic kidney disease (45, 54, 115, 116), yielding lifelong risk to both individuals. This review discusses recent guideline updates and recommendations along with current research on these long-term consequences of preeclampsia.

Abstract
It is estimated that women with CKD are ten times more likely to develop preeclampsia than women without CKD, with preeclampsia affecting up to 40% of pregnancies in women with CKD. However, the shared phenotype of hypertension, proteinuria, and impaired excretory kidney function complicates the diagnosis of superimposed preeclampsia in women with CKD who have hypertension and/or proteinuria that predates pregnancy. This article outlines the diagnoses of preeclampsia and superimposed preeclampsia. It discusses the pathogenesis of preeclampsia, including abnormal placentation and angiogenic dysfunction. The clinical use of angiogenic markers as diagnostic adjuncts for women with suspected preeclampsia is described, and the limited data on the use of these markers in women with CKD are presented. The role of kidney biopsy in pregnancy is examined. The management of preeclampsia is outlined, including important advances and controversies in aspirin prophylaxis, BP treatment targets, and the timing of delivery.

Abstract
BACKGROUND Preterm delivery is an independent risk factor for maternal cardiovascular disease. Little is known about the association between preterm delivery and maternal renal function. This study aimed to examine whether women who experience preterm delivery are at increased risk of subsequent chronic kidney disease (CKD) and end-stage kidney disease (ESKD). METHODS Using data from the Swedish Medical Birth Register, singleton live births from 1973 to 2012 were identified and linked to data from the Swedish Renal Register and National Patient Register (up to 2013). Gestational age at delivery was the main exposure and treated as a time-dependent variable. Primary outcomes were maternal CKD or ESKD. Cox proportional hazard regression models were used for analysis. RESULTS The dataset included 1,943,716 women who had 3,760,429 singleton live births. The median follow-up was 20.6 (interquartile range 9.9-30.0) years. Overall, 162,918 women (8.4%) delivered at least 1 preterm infant (< 37 weeks). Women who had any preterm delivery (< 37 weeks) were at increased risk of CKD (adjusted hazard ratio (aHR) 1.39, 95% CI 1.32-1.45) and ESKD (aHR 2.22, 95% CI 1.90-2.58) compared with women who only delivered at term (≥ 37 weeks). Women who delivered an extremely preterm infant (< 28 weeks) were at increased risk of CKD (aHR 1.84, 95% CI 1.52-2.22) and ESKD (aHR 3.61, 95% CI 2.03-6.39). The highest risk of CKD and ESKD was in women who experienced preterm delivery + preeclampsia (vs. non-preeclamptic term deliveries, for CKD, aHR 2.81, 95% CI 2.46-3.20; for ESKD, aHR 6.70, 95% CI 4.70-9.56). However, spontaneous preterm delivery was also associated with increased risk of CKD (aHR 1.32, 95% CI 1.25-1.39) and ESKD (aHR 1.99, 95% CI 1.67-2.38) independent of preeclampsia or small for gestational age (SGA). CONCLUSIONS Women with history of preterm delivery are at increased risk of CKD and ESKD. The risk is higher among women who had very preterm or extremely preterm deliveries, or whose preterm delivery was medically indicated. Women who experience spontaneous preterm delivery are at increased risk of long-term renal disease independent of preeclampsia or SGA. Preterm delivery may act as a risk marker for adverse maternal renal outcomes.

Longitudinal follow-up of kidney function in patients with a history of preeclampsia: From 11 to 18 years postpartum. Pregnancy Hypertens 2020; 19:187-189.

Abstract
Formerly preeclamptic (fPE) women are reported to have an increased risk to develop end stage kidney disease. To gain more insight in the course of kidney function after preeclampsia we assessed blood pressure, eGFR and urinary protein loss in 75 fPE women at 11 and 18 years postpartum. We found that during follow-up blood pressure did not increase and no cases of CKD were identified. Only a small decrease in eGFR (6-7 mL/min) and a small increase in urinary protein loss were observed, which fall within the expected range of normal aging. In conclusion, our data suggests that progression to kidney disease might not be a major concern in women after preeclampsia within 18 years postpartum.

Abstract
IMPORTANCE Adverse pregnancy outcomes, such as hypertensive disorders of pregnancy, gestational diabetes, and preterm delivery, are associated with increased risk of maternal cardiovascular disease. Little is known about whether adverse pregnancy outcomes are associated with increased risk of maternal chronic kidney disease (CKD) and end-stage kidney disease (ESKD). OBJECTIVE To review and synthesize the published literature on adverse pregnancy outcomes (hypertensive disorders of pregnancy, gestational diabetes, and preterm delivery) and subsequent maternal CKD and ESKD. DATA SOURCES PubMed, Embase, and Web of Science were searched from inception to July 31, 2019, for cohort and case-control studies of adverse pregnancy outcomes and maternal CKD and ESKD. STUDY SELECTION Selected studies included the following: a population of pregnant women, exposure to an adverse pregnancy outcome of interest, and at least 1 primary outcome (CKD or ESKD) or secondary outcome (hospitalization or death due to kidney disease). Adverse pregnancy outcomes included exposure to hypertensive disorders of pregnancy (preeclampsia, gestational hypertension, or chronic hypertension), preterm delivery (<37 weeks), and gestational diabetes. Three reviewers were involved in study selection. Of 5656 studies retrieved, 23 were eligible for inclusion. DATA EXTRACTION AND SYNTHESIS The Meta-analyses of Observational Studies in Epidemiology (MOOSE) guidelines were followed throughout. Three reviewers extracted data and appraised study quality. Random-effects meta-analyses were used to calculate overall pooled estimates using the generic inverse variance method. MAIN OUTCOMES AND MEASURES Primary outcomes included CKD and ESKD diagnosis, defined using established clinical criteria (estimated glomerular filtration rate or albuminuria values) or hospital records. The protocol for this systematic review was registered on PROSPERO (CRD42018110891). RESULTS Of 23 studies included (5 769 891 participants), 5 studies reported effect estimates for more than 1 adverse pregnancy outcome. Preeclampsia was associated with significantly increased risk of CKD (pooled adjusted risk ratio [aRR], 2.11; 95% CI, 1.72-2.59), ESKD (aRR, 4.90; 95% CI, 3.56-6.74), and kidney-related hospitalization (aRR, 2.65; 95% CI, 1.03-6.77). Gestational hypertension was associated with increased risk of CKD (aRR, 1.49; 95% CI, 1.11-2.01) and ESKD (aRR, 3.64; 95% CI, 2.34-5.66). Preterm preeclampsia was associated with increased risk of ESKD (aRR, 5.66; 95% CI, 3.06-10.48); this association with ESKD persisted for women who had preterm deliveries without preeclampsia (aRR, 2.09; 95% CI, 1.64-2.66). Gestational diabetes was associated with increased risk of CKD among black women (aRR, 1.78; 95% CI, 1.18-2.70), but not white women (aRR, 0.81; 95% CI, 0.58-1.13). CONCLUSIONS AND RELEVANCE In this meta-analysis, exposure to adverse pregnancy outcomes, including hypertensive disorders of pregnancy, gestational diabetes, and preterm delivery, was associated with higher risk of long-term kidney disease. The risk of ESKD was highest among women who experienced preeclampsia. A systematic approach may be warranted to identify women at increased risk of kidney disease, particularly after hypertensive disorders of pregnancy, and to optimize their long-term follow-up.

Preeclampsia and risk of end stage kidney disease: A Swedish nationwide cohort study. PLoS Med 2019; 16:e1002875.

Abstract
BACKGROUND Preeclampsia has been suggested to increase the risk of end-stage kidney disease (ESKD); however, most studies were unable to adjust for potential confounders including pre-existing comorbidities such as renal disease and cardiovascular disease (CVD). We aimed to examine the association between preeclampsia and the risk of ESKD in healthy women, while taking into account pre-existing comorbidity and potential confounders. METHODS AND FINDINGS Using data from the Swedish Medical Birth Register (MBR), women who had singleton live births in Sweden between 1982 and 2012, including those who had preeclampsia, were identified. Women with a diagnosis of chronic kidney disease (CKD), CVD, hypertension, or diabetes prior to the first pregnancy were excluded. The outcome was a diagnosis of ESKD, identified from the Swedish Renal Registry (SRR) from January 1, 1991, onwards along with the specified cause of renal disease. We conducted Cox proportional hazards regression analysis to examine the association between preeclampsia and ESKD adjusting for several potential confounders: maternal age, body mass index (BMI), education, native country, and smoking. This analysis accounts for differential follow-up among women because women had different lengths of follow-up time. We performed subgroup analyses according to preterm preeclampsia, small for gestational age (SGA), and women who had 2 pregnancies with preeclampsia in both. The cohort consisted of 1,366,441 healthy women who had 2,665,320 singleton live births in Sweden between 1982 and 2012. At the first pregnancy, women's mean (SD) age and BMI were 27.8 (5.13) and 23.4 (4.03), respectively, 15.2% were smokers, and 80.7% were native Swedish. The overall median (interquartile range [IQR]) follow-up was 7.4 years (3.2-17.4) and 16.4 years (10.3-22.0) among women with ESKD diagnosis. During the study period, 67,273 (4.9%) women having 74,648 (2.8% of all pregnancies) singleton live births had preeclampsia, and 410 women developed ESKD with an incidence rate of 1.85 per 100,000 person-years. There was an association between preeclampsia and ESKD in the unadjusted analysis (hazard ratio [HR] = 4.99, 95% confidence interval [CI] 3.93-6.33; p < 0.001), which remained in the extensively adjusted (HR = 4.96, 95% CI 3.89-6.32, p < 0.001) models. Women who had preterm preeclampsia (adjusted HR = 9.19; 95% CI 5.16-15.61, p < 0.001) and women who had preeclampsia in 2 pregnancies (adjusted HR = 7.13, 95% CI 3.12-16.31, p < 0.001) had the highest risk of ESKD compared with women with no preeclampsia. Considering this was an observational cohort study, and although we accounted for several potential confounders, residual confounding cannot be ruled out. CONCLUSIONS The present findings suggest that women with preeclampsia and no major comorbidities before their first pregnancy are at a 5-fold increased risk of ESKD compared with parous women with no preeclampsia; however, the absolute risk of ESKD among women with preeclampsia remains small. Preeclampsia should be considered as an important risk factor for subsequent ESKD. Whether screening and/or preventive strategies will reduce the risk of ESKD in women with adverse pregnancy outcomes is worthy of further investigation.

Abstract
Preeclampsia is a pregnancy-related syndrome of variable severity, classically characterized by acute kidney involvement, with hypertension and/or proteinuria and reduced kidney function. Once considered a self-limited disease healed by delivery, it is now acknowledged that preeclampsia can affect cardiovascular and kidney health in the long term. The entity of risk has not been established and consequently follow-up policies have not been defined. Here we undertook a systematic review to gain better insights into the need for post-preeclampsia follow-up. Articles published between January 2000 and March 2018 were selected, dealing with at least 20 preeclampsia patients, with follow-up of 4 years or more (MEDLINE, Embase, and Cochrane Library). No quality selection or language restriction was performed. Of the 10,510 titles and abstracts originally considered, 21 papers were selected, providing information on 110,803 cases with and 2,680,929 controls without preeclampsia, with partial overlap between studies on the same databases. Heterogeneity was high, and a random meta-analytic model selected. The increase in risk of end stage renal disease after preeclampsia was significant (meta-analytic risk ratios (95% confidence interval) 6.35 (2.73-14.79)); the risk of albuminuria and chronic kidney disease increased but statistical significance was not reached (4.31 (0.95-19.58) and 2.03 (0.58-7.32), respectively). Translating meta-analytic risk into the number of patients who need follow-up to detect one adverse event, 310 patients with preeclampsia are needed to identify one woman with end stage renal disease or four to identify one woman with albuminuria. Heterogeneity in definitions, insufficient follow-up and incomplete recruitment may account for discrepancies. Thus, preeclampsia significantly increases the risk of end stage renal disease. However, there is lack of sufficient data to show a relationship between preeclampsia, albuminuria and chronic kidney disease, underlining the need for further prospective studies.

Abstract
OBJECTIVE To investigate associations between pre-eclampsia and later risk of kidney disease. DESIGN Nationwide register based cohort study. SETTING Denmark. POPULATION All women with at least one pregnancy lasting at least 20 weeks between 1978 and 2015. MAIN OUTCOME MEASURE Hazard ratios comparing rates of kidney disease between women with and without a history of pre-eclampsia, stratified by gestational age at delivery and estimated using Cox regression. RESULTS The cohort consisted of 1 072 330 women followed for 19 994 470 person years (average 18.6 years/woman). Compared with women with no previous pre-eclampsia, those with a history of pre-eclampsia were more likely to develop chronic renal conditions: hazard ratio 3.93 (95% confidence interval 2.90 to 5.33, for early preterm pre-eclampsia (delivery <34 weeks); 2.81 (2.13 to 3.71) for late preterm pre-eclampsia (delivery 34-36 weeks); 2.27 (2.02 to 2.55) for term pre-eclampsia (delivery ≥37 weeks). In particular, strong associations were observed for chronic kidney disease, hypertensive kidney disease, and glomerular/proteinuric disease. Adjustment for cardiovascular disease and hypertension only partially attenuated the observed associations. Stratifying the analyses on time since pregnancy showed that associations between pre-eclampsia and chronic kidney disease and glomerular/proteinuric disease were much stronger within five years of the latest pregnancy (hazard ratio 6.11 (3.84 to 9.72) and 4.77 (3.88 to 5.86), respectively) than five years or longer after the latest pregnancy (2.06 (1.69 to 2.50) and 1.50 (1.19 to 1.88). By contrast, associations between pre-eclampsia and acute renal conditions were modest. CONCLUSION s Pre-eclampsia, particularly early preterm pre-eclampsia, was strongly associated with several chronic renal disorders later in life. More research is needed to determine which women are most likely to develop kidney disease after pre-eclampsia, what mechanisms underlie the association, and what clinical follow-up and interventions (and in what timeframe post-pregnancy) would be most appropriate and effective.

Abstract
Pregnancy-induced hypertension is a major cause of maternal and fetal morbidity and mortality. The overall strategies of defining and managing these conditions are aimed at preventing cardiovascular and cerebrovascular complications in the mother without jeopardizing fetal well-being. Our understanding of the origin of these disorders is evolving. Women with chronic hypertension should undergo a prepregnancy evaluation and close monitoring during and after pregnancy to ensure medication safety and to prevent end-organ damage. Based on available data, the current recommendation is that antihypertensive therapy should be initiated only in women with severe hypertension (defined as systolic blood pressure ≥160 mm Hg and/or diastolic blood pressure ≥105 mm Hg). It is now becoming more and more clear that hypertensive complications during pregnancy are potentially linked to cardiovascular, kidney, and metabolic diseases later in life. This review discusses the spectrum of hypertensive disorders of pregnancy, general management principles, and the need to monitor for long-term cardiovascular sequelae for decades afterward.

Abstract
BACKGROUND We examined the risk of adverse pregnancy outcomes in primiparous kidney donors compared to matched controls. METHODS Fifty-nine women with a history of kidney donation prior to their first pregnancy with normal renal function and no history of kidney disease, diabetes or chronic hypertension were matched 1:4 by age (within 2 years) and race to women with two kidneys using data from an integrated healthcare delivery system. Adverse pregnancy outcomes were defined as preterm delivery (delivery <37 weeks), delivery via cesarean section, gestational hypertension, preeclampsia/eclampsia, gestational diabetes, length of stay in the hospital >3 days, infant death/transfer to acute facility and low birthweight (<2500 g). RESULTS Living kidney donors did not have a higher risk of adverse outcomes compared to matched controls. There was a trend toward an increased risk of preeclampsia/eclampsia in kidney donors but it did not reach statistical significance (Odds ratio [OR]: 2.96, 95% CI: 0.98-8.94, P = 0.06). However, in kidney donors ≤30 years of age, there was a fourfold increased risk of preeclampsia/eclampsia (OR: 4.09, 95% CI: 1.07-15.59, P = 0.04). CONCLUSION Overall, the risk of pregnancy-associated complications following kidney donation is small but potential female kidney donors should be counseled on the possible increased risk of preeclampsia.

Abstract
Abstract
Preeclampsia is a hypertensive disorder of pregnancy and the clinical manifestation of severe endothelial dysfunction associated with maternal and foetal morbidity and mortality. The primum movens of the disease is the defect of invasion of the uterine arteries by foetal syncytiotrophoblasts, which causes a maladaptive placental response to chronic hypoxia and the secretion of the soluble form of type 1 vascular growth endothelial factor receptor, also called soluble fms-like tyrosine kinase 1 (sFlt-1), the major player in the pathophysiology of the disease. Among its different effects, sFlt-1 induces abnormal sensitivity of the maternal vessels to the vasoconstrictor angiotensin II. This leads to the hypertensive phenotype, recently shown to be abrogated by the administration of sildenafil citrate, which can potentiate the vasodilatory mediator nitrite oxide. This review focuses on the mechanisms of maternal endothelial dysfunction in preeclampsia and discusses the therapeutic window of sildenafil use in the context of preeclampsia, based on the results from preclinical studies and clinical trials. Safety issues recently reported in neonates have considerably narrowed this window.

Abstract
Pregnancy-related acute kidney injury (pAKI), preeclampsia (PE), and the hypertensive disorders of pregnancy are closely related conditions, which are, in turn, frequently linked to pre-existing and often non-diagnosed chronic kidney disease (CKD). The current literature and research mainly underline the effects of pregnancy complications on the offspring; this review strongly emphasizes the maternal health as well. These conditions not only negatively affect pregnancy outcomes, but have a relevant effect on the future health of affected mothers and their children. Therefore, dedicated diagnostic and follow-up programs are needed, for optimizing materno-foetal health and reducing the impact of pregnancy-related problems in the mothers and in the new generations. This narrative review, performed on the occasion of the 2018 World Kidney Day dedicated to women’s health, focuses on three aspects of the problem. Firstly, the risk of AKI in the hypertensive disorders of pregnancy (the risk is the highest in developing countries; however PE is the main cause of pregnancy related AKI worldwide). Secondly, the effect of AKI and the hypertensive disorders of pregnancy on the development of CKD in the mother and offspring: long-term risks are increased; the entity and the trajectories are still unknown. Thirdly, the role of CKD in the pathogenesis of AKI and the hypertensive disorders of pregnancy: CKD is a major risk factor and the most important element in the differential diagnosis; pregnancy is a precious occasion for early diagnosis of CKD. Higher awareness on the importance of AKI in pregnancy is needed to improve short and long term outcomes in mothers and children.

Schlembach D, Hund M, Schroer A, Wolf C. Economic assessment of the use of the sFlt-1/PlGF ratio test to predict preeclampsia in Germany. BMC Health Serv Res 2018; 18:603. [PMID: 30081904 PMCID: PMC6080558 DOI: 10.1186/s12913-018-3406-1] [Citation(s) in RCA: 41] [Impact Index Per Article: 6.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/16/2017] [Accepted: 07/19/2018] [Indexed: 12/11/2022] Open
Abstract
Background The PRediction of short-term Outcome in preGNant wOmen with Suspected preeclampsIa Study (PROGNOSIS) demonstrated that a soluble fms-like tyrosine kinase 1/placental growth factor (sFlt-1/PlGF) ratio ≤ 38 ruled out the occurrence of preeclampsia in the next week with a negative predictive value of 99.3%; a ratio > 38 indicates an increased risk of developing preeclampsia in the next 4 weeks. We performed an assessment of the economic impact of the sFlt-1/PlGF ratio test for short-term prediction of preeclampsia in Germany. Methods We adapted a cost-effectiveness model, which had been developed to estimate the incremental value of adding the sFlt-1/PlGF ratio test with a cut-off ratio of 38 to standard diagnostic procedures for guiding the management of women with suspected preeclampsia in the UK. We used the adapted model to estimate the incremental value of the sFlt-1/PlGF ratio test (cut-off 38) for guiding the management of women with suspected preeclampsia from a German Diagnosis-Related Group (DRG) payer perspective. The economic model estimated costs associated with diagnosis and management of preeclampsia in women managed in either a ‘no-test’ scenario in which clinical decisions are based on standard diagnostic procedures alone, or a ‘test’ scenario in which the sFlt-1/PlGF test is used in addition to standard diagnostic procedures. Test characteristics and rates of hospitalization were derived from patient-level data from PROGNOSIS. The main outcome measure from the economic model was the total cost per patient. Results In the model adapted to the German DRG payer system, introduction of the sFlt-1/PlGF ratio test with a cut-off value of 38 could reduce the proportion of women hospitalized in Germany from 44.6 to 24.0%, resulting in an expected cost saving of €361 per patient. Conclusions The sFlt-1/PlGF ratio test is likely to reduce unnecessary hospitalization of women with a low risk of developing preeclampsia, and identify those at high risk to ensure appropriate management. Even within the restrictions of the DRG system in Germany, this results in substantial cost savings for women with suspected preeclampsia.

Abstract
Preeclampsia is a serious complication of pregnancy where it affects 5–8% of all pregnancies. It increases the morbidity and mortality of both the fetus and pregnant woman, especially in developing countries. It deleteriously affects several vital organs, including the kidneys, liver, brain, and lung. Although, the pathogenesis of preeclampsia has not yet been fully understood, growing evidence suggests that aberrations in the angiogenic factors levels and coagulopathy are responsible for the clinical manifestations of the disease. The common nominator of tissue damage of all these target organs is endothelial injury, which impedes their normal function. At the renal level, glomerular endothelial injury leads to the development of maternal proteinuria. Actually, peripheral vasoconstriction secondary to maternal systemic inflammation and endothelial cell activation is sufficient for the development of preeclampsia-induced hypertension. Similarly, preeclampsia can cause hepatic and neurologic dysfunction due to vascular damage and/or hypertension. Obviously, preeclampsia adversely affects various organs, however it is not yet clear whether pre-eclampsia per se adversely affects various organs or whether it exposes underlying genetic predispositions to cardiovascular disease that manifest in later life. The current review summarizes recent development in the pathogenesis of preeclampsia with special focus on novel diagnostic biomarkers and their relevance to potential therapeutic options for this disease state. Specifically, the review highlights the renal manifestations of the disease with emphasis on the involvement of angiogenic factors in vascular injury and on how restoration of the angiogenic balance affects renal and cardiovascular outcome of Preeclamptic women.

Abstract
Background The epidemiology of ESRD requiring maintenance dialysis (ESRD-D) in large, diverse immigrant populations is unclear.Methods We estimated ESRD-D prevalence and incidence among immigrants in Ontario, Canada. Adults residing in Ontario in 2014 were categorized as long-term Canadian residents or immigrants according to administrative health and immigration datasets. We determined ESRD-D prevalence among these adults and calculated age-adjusted prevalence ratios (PRs) comparing immigrants to long-term residents. Among those who immigrated to Ontario between 1991 and 2012, age-adjusted ESRD-D incidence was calculated by world region and country of birth, with immigrants from Western nations as the referent group.Results Among 1,902,394 immigrants and 8,860,283 long-term residents, 1700 (0.09%) and 8909 (0.10%), respectively, presented with ESRD-D. Age-adjusted ESRD-D prevalence was higher among immigrants from sub-Saharan Africa (PR, 2.17; 95% confidence interval [95% CI], 1.84 to 2.57), Latin America and the Caribbean (PR, 2.11; 95% CI, 1.90 to 2.34), South Asia (PR, 1.45; 95% CI, 1.32 to 1.59), and East Asia and the Pacific (PR, 1.34; 95% CI, 1.22 to 1.46). Immigrants from Somalia (PR, 4.18; 95% CI, 3.11 to 5.61), Trinidad and Tobago (PR, 2.88; 95% CI, 2.23 to 3.73), Jamaica (PR, 2.88; 95% CI, 2.40 to 3.44), Sudan (PR, 2.84; 95% CI, 1.53 to 5.27), and Guyana (PR, 2.69; 95% CI, 2.19 to 3.29) had the highest age-adjusted ESRD-D PRs relative to long-term residents. Immigrants from these countries also exhibited higher age-adjusted ESKD-D incidence relative to Western Nations immigrants.Conclusions Among immigrants in Canada, those from sub-Saharan Africa and the Caribbean have the highest ESRD-D risk. Tailored kidney-protective interventions should be developed for these susceptible populations.

Association Between Hypertensive Disorders During Pregnancy and the Subsequent Risk of End-Stage Renal Disease: A Population-Based Follow-Up Study. JOURNAL OF OBSTETRICS AND GYNAECOLOGY CANADA 2018; 40:1129-1138. [PMID: 29934233 DOI: 10.1016/j.jogc.2018.01.022] [Citation(s) in RCA: 19] [Impact Index Per Article: 3.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/10/2017] [Accepted: 01/13/2018] [Indexed: 11/23/2022]
Abstract
OBJECTIVE To assess whether hypertensive disorders during pregnancy (HDPs) are associated with the subsequent development of end-stage renal disease (ESRD). METHODS The present study included 1 598 043 women who delivered in Canadian hospitals between April 1993 and March 2003. The baseline information was from the Canadian Institute for Health Information's Discharge Abstract Database. Women with chronic kidney disease, diabetes mellitus, and other specific conditions were excluded. A follow-up study was conducted through a record linkage on their hospitalizations as of the 13th month after the delivery discharge through March 31, 2013. The primary outcome of interest was subsequent hospitalization due to ESRD. Cox model was used to quantify the association between HDPs and ESRD hospitalization. RESULTS There occurred 9.9 and 1.7 ESRD hospitalizations per 100 000 person-years in the follow-up of HDPs and non-HDP women, respectively. An increased risk of ESRD hospitalization was observed in pregnant women with pre-eclampsia/eclampsia (adjusted hazard ratio [aHR] = 4.7, 95% CI 3.6-6.0), unspecified HDPs (aHR = 4.6, 95% CI 2.8-7.7), or gestational hypertension (aHR = 3.3, 95% CI 2.1-5.1). Caesarean delivery, preterm delivery, IUGR, and deep vein thrombosis were identified as significant correlates with the subsequent ESRD hospitalization. The risk of subsequent ESRD hospitalization appeared to be lower for women who had ≥2 deliveries compared with those who had one delivery during the study period. CONCLUSION Pregnancy complicated with HDPs was significantly associated with an increased risk of ESRD hospitalization in later life, and this association varied by HDP subtype and frequency of delivery.

Abstract
OBJECTIVE Formerly preeclamptic women have an increased risk for cardiovascular and renal disease later in life. It is unknown which mechanisms contribute to this increased risk and whether this is induced by preeclampsia or by prepregnancy factors. We hypothesized that the increased risk for cardiovascular disease is partly due to an increased angiotensin II (ang II) responsiveness postpartum and that preeclampsia itself is involved in inducing this increased ang II responsiveness. METHODS In never-pregnant, formerly healthy pregnant rats and rats with former experimental preeclampsia [experimental preeclampsia model induced by low-dose endotoxin infusion on day 14 of pregnancy; endotoxin-infused pregnant rats (EP-rats)], ang II responsiveness was studied by measuring changes in blood pressure (BP) and proteinuria after chronic ang II infusion with osmotic minipumps (200 ng/kg per min). In addition, we measured BP and responses to ang II (0.3, 1.0 and 3.0 ng/kg per min) in 18 formerly early-onset preeclamptic, without comorbidities, and 18 formerly healthy pregnant women (controls). RESULTS In rats, a significantly higher systolic BP at termination was observed in formerly EP-rats vs. never-pregnant rats after ang II infusion (159.5 ± 29.5 vs. 136.7 ± 16.8; P = 0.049). In response to ang II, there was a significant increase in proteinuria in formerly EP-rats vs. healthy pregnant and never-pregnant rats (P < 0.01 for both). In humans, 1.0 ng/kg per min ang II showed a trend towards an increased mean arterial BP response in formerly preeclamptic women vs. controls (P = 0.057). CONCLUSION Our data show an increased ang II responsiveness following (experimental) preeclampsia and support a role for preeclampsia itself in altered ang II responsiveness postpartum.

Abstract
Introduction: preeclampsia can be associated with future renal disease. Objectives: To measure changes in renal function overtime in patients with
preeclampsia. Methods: urine and serum samples from eleven patients with preeclampsia and eight
patients with a normal pregnancy were obtained during pregnancy, postpartum,
and 3 years after delivery. Urine podocalyxin, protein, and serum creatinine
were measured. Results: after 3 years, there were no significant differences in urinary podocalyxin
in patients with or without preeclampsia: 4.34 ng/mg [2.69, 8.99]
vs. 7.66 ng/mg [2.35, 13], p = 0.77.
The same applied to urinary protein excretion: 81.5 mg/g [60.6, 105.5]
vs. 43.2 mg/g [20.9, 139.3] p = 0.23.
Serum creatinine was 0.86 mg/dL [0.7, 0.9] vs. 0.8 mg/dL
[0.68, 1] p = 0.74 in those with and without preeclampsia.
In normal patients, urinary podocalyxin decreased from 54.4 ng/mg [34.2,
76.9] during pregnancy to 7.66 ng/mg [2.35, 13] three years after pregnancy,
p = 0.01. Proteinuria decreased from 123.5 mg/g [65.9,
194.8] to 43.2 mg/g [20.9, 139.3], p = 0.12. In
preeclampsia patients, urinary podocalyxin decreased from 97.5 ng/mg [64.9,
318.4] during pregnancy to 37.1 ng/mg within one week post-partum [21.3,
100.4] p = 0.05 and 4.34 ng/mg [2.69, 8.99] three years
after, p = 0.003. Proteinuria was 757.2 mg/g [268.4,
5031.7] during pregnancy vs. 757.2 mg/g [288.2, 2917]
postpartum, p = 0.09 vs. 81.5 mg/g [60.6,
105.5] three years later, p = 0.01. Two patients still had
proteinuria after 3 years. Conclusions: in preeclampsia patients, postpartum urinary podocalyxin decreased before
proteinuria. After three years, serum creatinine, urinary podocalyxin, and
protein tended to normalize, although some patients still had
proteinuria.

Abstract
Background Data on the prevalence of persistent symptoms in the first year after preeclampsia are limited. Furthermore, possible risk factors for these sequelae are poorly defined. We investigated kidney function, blood pressure, proteinuria and urine sediment in women with preeclampsia 6 months after delivery with secondary analysis for possible associated clinical characteristics. Methods From January 2007 to July 2014 all women with preeclampsia and 6-months follow up at the University Hospital Basel were analyzed. Preeclampsia was defined as new onset of hypertension (≥140/90 mmHg) and either proteinuria or signs of end-organ dysfunction. Hypertension was defined as a blood pressure ≥ 140/90 mmHg or the use of antihypertensive medication. Proteinuria was defined as a protein-to-creatinine ratio in a spot urine > 11 mg/mmol. Urine sediment was evaluated by a nephrologist. Secondary analyses were performed to investigate for possible parameters associated with persistent symptoms after preeclampsia. Results Two hundred two women were included into the analysis. At a mean time of follow up of 172 days (+/− 39.6) after delivery, mean blood pressure was 124/76 mmHg (+/− 14/11, range 116–182/63–110) and the mean serum-creatinine was 61.8 μmol/l (33–105 μmol/l) (normal < 110 μmol/l). Mean estimated glomerular filtration rate using CKD-EPI was 110.7 mml/min/1.73m2 (range 59.7–142.4 mml/min/1.73m2) (normal > 60 mml/min/1.73m2). 20.3% (41/202) had a blood pressure of 140/90 mmHg or higher (mean 143/89 mmHg) or were receiving antihypertensive medication (5.5%, 11/202). Proteinuria was present in 33.1% (66/199) (mean 27.5 mg/mmol). Proteinuria and hypertension was present in 8% (16/199). No active urine sediment (e.g. signs of glomerulonephritis) was observed. Age and gestational diabetes were associated with persistent proteinuria and severe preeclampsia with eGFR decline of ≥ 10 ml/min/1.73m2. Conclusion Hypertension and proteinuria are common after 6 months underlining the importance of close follow up to identify those women who need further care.

Abstract
Preeclampsia continues to afflict 5% to 8% of all pregnancies throughout the world and is associated with significant morbidity and mortality to the mother and the fetus. Although the pathogenesis of the disorder has not yet been fully elucidated, current evidence suggests that imbalance in angiogenic factors is responsible for the clinical manifestations of the disorder, and may explain why certain populations are risk. In this review, we begin by demonstrating the roles that angiogenic factors play in pathogenesis of preeclampsia and its complications in the mother and the fetus. We then continue to report on the use of angiogenic markers as biomarkers to predict and risk-stratify disease. Strategies to treat preeclampsia by correcting the angiogenic balance, either by promoting proangiogenic factors or by removing antiangiogenic factors in both animal and human studies, are discussed. We end the review by summarizing status of the current preventive strategies and the long-term cardiovascular outcomes of women afflicted with preeclampsia.

Abstract
Pregnant women are uniquely susceptible to adverse effects of air pollution exposure due to vulnerabilities and health consequences during pregnancy (e.g., hypertensive disorders of pregnancy [HDP]) compared to the general population. Because the Clean Air Act (CAA) creates a duty to protect at-risk groups, the regulatory assessment of at-risk populations has both policy and scientific foundations. Previously, pregnant women have not been specially protected in establishing the margin of safety for the ozone and particulate matter (PM) standards. Due to physiological changes, pregnant women can be at greater risk of adverse effects of air pollution and should be considered an at-risk population. Women with preexisting conditions, women experiencing poverty, and groups that suffer systematic discrimination may be particularly susceptible to cardiac effects of air pollutants during pregnancy. We rigorously reviewed 11 studies of over 1.3 million pregnant women in the United States to characterize the relationship between ozone or PM exposure and HDP. Findings were generally mixed, with a few studies reporting a joint association between ozone or PM and social determinants or pre-existing chronic health conditions related to HDP. Adequate evidence associates exposure to PM with an adverse effect of HDP among pregnant women not evident among non-gravid populations.
