Abstract
BACKGROUND Preeclampsia, a new-onset hypertensive disorder of pregnancy, is associated with lifetime cardiovascular disease risk, but less is known about risk after other pregnancy-related hypertension. METHODS AND RESULTS The Northern Finland Birth Cohort 1966 included all expected births from 1 year (N=12 055 women). Blood pressure measurements and other prospective data were determined from prenatal care records and questionnaires for 10 314 women. Subsequent diagnoses were ascertained from Finnish registries (average follow-up, 39.4 years). Adjusted hazard ratios (HRs) with 95% confidence intervals (CIs) estimate risks in hypertensive women compared with normotensive women. Hypertension during pregnancy was associated with increased risk of subsequent cardiovascular disease and arterial hypertension. Women with chronic hypertension and superimposed preeclampsia/eclampsia had high risk for future diseases. Gestational hypertension was associated with increased risk of ischemic heart disease (HR, 1.44 [95% CI, 1.24-1.68]), myocardial infarcts (HR, 1.75 [95% CI, 1.40-2.19]), myocardial infarct death (HR, 3.00 [95% CI, 1.98-4.55]), heart failure (HR, 1.78 [95% CI, 1.43-2.21]), ischemic stroke (HR, 1.59 [95% CI, 1.24-2.04]), kidney disease (HR, 1.91 [95% CI, 1.18-3.09]), and diabetes mellitus (HR, 1.52 [95% CI, 1.21-1.89]). Isolated systolic hypertension was associated with increased risk of myocardial infarct death (HR, 2.15 [95% CI, 1.35-3.41]), heart failure (HR, 1.43 [95% CI, 1.13-1.82]), and diabetes mellitus (HR, 1.42 [95% CI, 1.13-1.78]), whereas isolated diastolic hypertension was associated with increased risk of ischemic heart disease (HR, 1.26 [95% CI, 1.05-1.50]). Results were similar in nonsmoking women aged <35 years with normal weight and no diabetes mellitus during pregnancy. CONCLUSIONS Elevated blood pressure during pregnancy, regardless of type and even without known risk factors, signals high risk of later cardiovascular disease, chronic kidney disease, and diabetes mellitus. Clinical monitoring, risk factor evaluation, and early intervention could benefit women with hypertension in pregnancy.

Abstract
With appropriate multi-disciplinary team care, most women with diabetic nephropathy will have successful pregnancy outcomes; however, pregnancy complications are increased compared to non-diabetic individuals, particularly in those with poor glycaemic control. Women with more severe renal impairment, especially those with hypertension and proteinuria at are highest risk of worse pregnancy outcomes and deterioration in pre-existing renal function. Pre-pregnancy counselling should be offered to all women with diabetes in order to optimise diabetic care, and inform women of potential complications. Pregnancy is an indicator of long-term health, and may indicate important issues for the future management of women with diabetic nephropathy.

BMC Pregnancy Childbirth 2013; 13:61. [PMID: 23497157 PMCID: PMC3605330 DOI: 10.1186/1471-2393-13-61] [Citation(s) in RCA: 46] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/08/2013] [Accepted: 03/04/2013] [Indexed: 11/21/2022] Open
Abstract
Background Preeclampsia (PE), a hypertensive disorder of pregnancy affects 2-8% of women and is associated with increased cardiovascular disease (CVD) risk later in life. There is little information about the knowledge of obstetrician-gynecologists in German outpatient care setting regarding the future health risk of PE and knowledge of the current guidelines on treatment and counseling patients post PE. This study aimed to assess whether obstetrician-gynecologists are aware of PE’s association with maternal long-term adverse outcomes and providing appropriate counseling. Methods A random sample of 500 obstetrician-gynecologists in the federal state of Lower Saxony was mailed a survey and a reminder with a second copy of the survey. The questionnaire elicited both personal information, and knowledge on future disease risks, e.g. cardiovascular disease (CVD) and current guidelines as well as on counseling practice. Descriptive analysis was used to analyze the responses. Results A total of 212 obstetrician-gynecologists (42.4%) responded to the questionnaire. A large proportion of physicians stated that PE was associated with a higher risk for the development for hypertension (86.6%), stroke (78.5%) and kidney disease (78.0%). Of the participants 75.8% reported that women after PE have a shorter life expectancy. Respondents with knowledge of the current guidelines of the German Association of Obstetrics and Gynecology concerning follow up and risk management of PE (45.2%) were more often aware of the development of CVD and stroke and counseled patients on self -blood-pressure measurement, meaning and long-term-risks of PE and attached importance to family history of PE compared to physicians with no knowledge of the guidelines. Conclusion Although the majority of obstetrician-gynecologists were aware of higher CVD risk after PE, weaknesses exist in the follow up care and counseling of these patients. These deficiencies would be amendable to directed educational activities to improve the implementation of current guidelines.

Abstract
BACKGROUND Studies into the association between hypertensive disorders during pregnancy and end-stage renal disease are limited. We investigated the risk of end-stage renal disease after delivery among women with hypertensive disorders during pregnancy. METHODS We used insurance claims data from 1998 to 2009 to identify 26,651 women aged 19-40 years old who experienced hypertensive disorders during pregnancy; these women had no history of hypertension, diabetes, kidney disease or lupus. We also randomly selected 213,397 women without hypertensive disorders during pregnancy as a comparison cohort; the frequency was matched by age and index year of pregnancy. We compared the incidence of end-stage renal disease in the 2 cohorts. We calculated hazard ratios (HRs) and 95% confidence intervals (CIs) after controlling for demographic and clinical factors. RESULTS Women with hypertensive disorders during pregnancy had a greater risk of chronic kidney disease and end-stage renal disease, with adjusted HRs of 9.38 (95% CI 7.09-12.4) and 12.4 (95% CI 8.54-18.0), respectively, after controlling for urban status, coronary artery disease, congestive heart failure, hyperlipidemia and abruption. The HR for end-stage renal disease was 2.72 (95% CI 1.76-4.22) after we also controlled for hypertension and diabetes. Women with preeclampsia or eclampsia had a higher risk of end-stage renal disease (adjusted HR 14.0, 95% CI 9.43-20.7) than women who had gestational hypertension only (adjusted HR 9.03, 95% CI 5.20-15.7). INTERPRETATION Women with hypertensive disorders during pregnancy were at a high risk of end-stage renal disease. The risk was much greater for women who had preeclampsia or eclampsia than those who had gestational hypertension only.

Abstract
BACKGROUND Vascular alterations are present in pregnant women affected by preeclampsia. In this study, we assessed arterial compliance in women affected by hypertensive disorders of pregnancy. We hypothesized that arterial compliance is reduced in women affected by preeclampsia. METHODS Forty-three hypertensive pregnant women undergoing evaluation for preeclampsia were studied. Clinical data about each patient and pregnancy were collected. Large (C1) and small (C2) artery compliance were assessed by radial tonometry, while the patients underwent laboratory tests to diagnose preeclampsia. At the time of delivery, gestational age and newborn data were recorded. RESULTS Eighteen women were diagnosed with preeclampsia. C2 levels were lower among preeclamptic versus hypertensive aproteinuric women (mean ± SD, 4.5 ± 1.3 vs 5.9 ± 2.3 mL/mm Hg · 100, P = 0.013, 95% confidence interval [CI] of difference 0.32-2.55), whereas C1 levels did not differ. In the preeclampsia group, C2 levels correlated with urine total protein concentrations measured the same day (Spearman ρ = -0.49, P = 0.047, upper 95% CI -0.01) and with gestational age at first occurrence of hypertension (Spearman ρ = 0.59, P = 0.010, lower 95% CI 0.17). Among singleton gestations, C2 also correlated with newborn birth weight measured at delivery (Spearman ρ = 0.43, P = 0.009, lower 95% CI 0.11). Women who were hypertensive but aproteinuric at the time of compliance assessment, but who subsequently developed preeclampsia (n = 6), had C2 levels similar to those with an early diagnosis of preeclampsia (mean difference 0.37 mL/mm Hg · 100, 95% CI -2.42 to 1.67) and lower C2 levels than women diagnosed with gestational hypertension (P = 0.019, 95% CI 0.33-4.42 mL/mm Hg · 100). CONCLUSIONS The noninvasive assessment of arterial elasticity may contribute toward characterization of the nature of the pathophysiology in pregnancy-induced hypertensive disorders. The vascular alterations of the small arteries, as assessed by C2, may reflect the extent of vascular alterations present with preeclampsia.

Abstract
Cardiovascular disease claims more women's lives than any other disease. Hypertension is an important risk factor for cardiovascular disease in women but is often underestimated and undiagnosed and there is an ongoing misperception that women are at a lower risk of cardiovascular disease than men. The attainment of clinical blood pressure goals can markedly reduce cardiovascular morbidity and mortality, yet approximately two-thirds of treated hypertensive women have uncontrolled blood pressure. Furthermore, there are special risk factors that are unique for women that needs acknowledgement in order to help prevent the great number of hypertension-related events in women. Guidelines for treatment of hypertension are similar for men and women. More studies on the interaction between gender and response to antihypertensive drugs would be of interest.

Abstract
Background Obstetrical interventions during childbirth vary widely across European and North American countries. Regional differences in intrapartum care may reflect an inpatient-based, clinician-oriented, interventional practice style. Methods Using nationally representative hospital discharge data, a retrospective cohort study was conducted to explore regional variation in obstetric intervention across four major regions (Dublin Mid Leinster; Dublin Northeast; South; West) within the Republic of Ireland. Specific focus was given to rates of induction of labour, caesarean delivery, epidural anaesthesia, blood transfusion, hysterectomy and episiotomy. Logistic regression analyses were performed to assess the association between geographical region and interventions while adjusting for patient case-mix. Results 323,588 deliveries were examined. The incidence of interventions varied significantly across regions; the greatest disparities were observed for rates of induction of labour and caesarean delivery. Women in the South had nearly two-fold odds of having prostaglandins (adjusted OR: 1.75, 95% CI 1.68-1.82), whereas women in the West had 1.85 odds (95% CI 1.77-1.93) of artificial rupture of membrane. Women delivering in the Dublin Northeast, South and West regions had more than two-fold increased odds of elective caesarean delivery relative to women delivering in the Dublin Mid Leinster region. The Dublin Northeast region had the highest odds of emergency caesarean delivery (adjusted OR: 1.36; 95% CI: 1.31-1.40). Conclusions Substantial regional variation in intrapartum care was observed within this small, relatively homogeneous population. The association of intervention use with region illustrates the need to encourage uptake of scientific based practice guidelines to better inform clinical judgment.

Abstract
BACKGROUND AND OBJECTIVES CKD and multiple pregnancies bear important risks for pregnancy outcomes. The aim of the study was to define the risk for adverse pregnancy-related outcomes in multiple pregnancies in CKD patients in comparison with a control group of "low-risk" multiple pregnancies. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS The study was performed in the Maternal Hospital of the University of Turin, Italy. Of 314 pregnancies referred in CKD (2000-2011), 20 were multiple (15 twin deliveries). Control groups consisted of 379 low-risk multiple pregnancies (314 twin deliveries) and 19 (15 twin deliveries) cases with hypertension-collagen diseases. Baseline data and outcomes were compared by univariate and logistic regression analyses. RESULTS The prevalence of multiple pregnancies was relatively high in the CKD population (6.4%); all referred cases were in early CKD stages (I-II); both creatinine (0.68 to 0.79 mg/dl; P=0.010) and proteinuria (0.81 to 3.42 g/d; P=0.041) significantly increased from referral to delivery. No significant difference in demographic data at baseline was found between cases and low-risk controls. CKD was associated with higher risk of adverse pregnancy outcomes versus low-risk twin pregnancies. Statistical significance was reached for preterm delivery (<34 weeks: 60% vs 26.4%; P=0.005; <32 weeks: 53.3% vs 12.7%; P<0.001), small for gestational age babies (28.6% vs 8.1%; P<0.001), need for Neonatal Intensive Care Unit (60% vs 12.7%; P<0.001), weight discordance between twins (40% vs 17.8%; P=0.032), and neonatal and perinatal mortality (6.6% vs 0.8%; P=0.032). CONCLUSION This study suggests that maternal-fetal risks are increased in multiple pregnancies in the early CKD stages.

Abstract
Risk of hypertension in mother and offspring after preeclampsia is greater if preeclampsia develops early in pregnancy. We investigated whether those who develop early onset disease have unique adverse blood pressure characteristics. One hundred forty women were studied 6 to 13 years either after a pregnancy complicated by preeclampsia (45 women with early onset preeclampsia before 34 weeks gestation and 45 women with late-onset preeclampsia) or after a normotensive pregnancy (50 women). Forty-seven offspring from these pregnancies also participated. Data on maternal antenatal and postnatal blood pressures were extracted from maternity records and related to peripheral, central, and ambulatory blood pressure measurements in later life. Compared with late-onset preeclampsia, early onset preeclampsia was associated with higher diastolic blood pressure 6 weeks postnatally (86.25±13.46 versus 75.00±5.00 mm Hg,
P
<0.05), a greater increase in blood pressure relative to booking blood pressure over the subsequent 6 to 13 years, and higher nocturnal systolic and diastolic blood pressures in later life (111.07±13.18 versus 101.13±11.50 mm Hg,
P
=0.04, and 67.00±7.25 versus 58.60±5.79 mm Hg,
P
=0.002). Furthermore, at age 6 to 13 years their offspring had higher systolic blood pressure compared with those born to late-onset preeclampsia (96.27±7.30 versus 88.39±7.57 mm Hg,
P
=0.005). Mothers who developed early onset preeclampsia, and the offspring of that pregnancy display specific adverse blood pressure characteristics later in life. These are not evident in mothers and offspring after late-onset preeclampsia or normotensive pregnancy.

Abstract
BACKGROUND AND OBJECTIVES Women with preeclampsia have increased risk of developing ESRD. This study assessed whether this can be explained by preeclampsia itself or by familial aggregation of common risk factors. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS Since 1967, the Medical Birth Registry of Norway has registered data on all births in the country. By linkage with the Norwegian Population Registry, different, but overlapping, cohorts were defined: the first and second cohorts included women and a sibling (first cohort) or child (second cohort) with a registered first birth between 1967 and 2008. Similar cohorts were defined for men. The Norwegian Renal Registry provided data on ESRD from 1980 to June 2009. RESULTS Cohort 1 was used for the main analyses and included 570,675 women, 291 of whom developed ESRD after a median 18.2 years. Compared with women without preeclampsia and no siblings with preeclampsia, women without preeclampsia but a sibling with preeclampsia had a relative risk (RR) of ESRD of 0.96 (95% confidence interval, 0.59-1.6), women with preeclampsia but no siblings with preeclampsia had a RR of 6.0 (4.4-8.1), and women with preeclampsia and a sibling with preeclampsia had a RR of 2.8 (0.88-8.6). Further analyses of women showed no increased risk of ESRD if a child had preeclampsia in first pregnancy. CONCLUSIONS Familial aggregation of risk factors does not seem to explain increased ESRD risk after preeclampsia. These findings support the hypothesis that preeclampsia per se may lead to kidney damage.

Abstract
Pre-eclampsia is a syndrome of pregnancy, defined by the gestational-onset of hypertension and proteinuria, which resolves postpartum. This definition does not consider the variable multiorgan involvement of a syndrome that can include seizures, fulminating hepatic necrosis and a consumptive coagulopathy. These disparate clinical features are a consequence of an accelerated but transient metabolic syndrome with widespread maternal endothelial dysfunction and inflammation. A trigger to this maternal state is the relatively ischaemic placenta. As pregnancy progresses, the concentration of vaso-toxic factors released by the relatively ischaemic placenta gradually builds up in the maternal circulation. Those predisposed to endothelial dysfunction, e.g. women with risk factors for cardiovascular disease, are more sensitive to these placental derived factors and will develop pre-eclampsia before natural onset of labour. A woman's vulnerability to pre-eclampsia is therefore composed of a unique balance between her pre-existing maternal endothelial and metabolic health and the concentration of placental derived factors toxic to maternal endothelium. Delivery of the placenta remains the only cure. Years later, women who had pre-eclampsia are at increased risk of chronic hypertension, ischaemic heart disease, cerebrovascular disease, kidney disease, diabetes mellitus, thromboembolism, hypothyroidism and even impaired memory. This article describes how a brief, usually single episode of this acute pregnancy syndrome might both identify those vulnerable to chronic disease in later life and in some cases initiate chronic disease.

Abstract
Cardiovascular and neuroendocrine reactivity to acute stress are important predictors of health outcomes in non-pregnant populations. Greater magnitude and duration of physiological responses have been associated with increased risk of hypertensive disorders and diabetes, greater susceptibility to infectious illnesses, suppression of cell-mediated immunity as well as risk for depression and anxiety disorders. Stress reactivity during pregnancy has unique implications for maternal health, birth outcomes, and fetal development. However, as compared to the larger literature, our understanding of the predictors and consequences of exaggerated stress reactivity in pregnancy is limited. This paper reviews the current state of this literature with an emphasis on gaps in knowledge and future directions.

Abstract
Preeclampsia is a common complication of pregnancy associated with high maternal morbidity and mortality and intrauterine fetal growth restriction. There is extensive evidence that the reduction of uteroplacental blood flow in this syndrome results from the toxic combination of hypoxia, imbalance of angiogenic and antiangiogenic factors, inflammation, and deranged immunity. Women treated for preeclampsia also have an increased risk for cardiovascular and renal disease. At present it is unclear if the increased cardiovascular and renal disease risks are due to residual and or progressive effects of endothelial damage from the preeclampsia or from shared risk factors between preeclampsia and cardiac disease. Moreover, it appears that endothelin-1 signaling may play a central role in the hypertension associated with preeclampsia. In this paper, we discuss emerging data on the pathogenesis of preeclampsia and review therapeutic options.

Abstract
BACKGROUND Chronic kidney disease (CKD) has a high prevalence in pregnancy. In a period of cost constraints, there is the need for identification of the risk pattern and for follow-up. METHODS Patients were staged according to K-DOQI guidelines. The analysis was prospective, January 2000-June 2011. Two hundred and forty-nine pregnancies were observed in 225 CKD patients; 176 singleton deliveries were recorded. The largest group encompasses stage 1 CKD patients, with normal renal function, in which 127 singleton deliveries were recorded. No hard outcomes occurred (death; dialysis); therefore, surrogate outcomes were analysed [caesarean section, prematurity, need for neonatal intensive care unit (NICU)]. Stage 1 patients were compared with normal controls (267 low-risk pregnancies followed in the same setting) and with patients with CKD stages 2-4 (49 singleton deliveries); two referral patterns were also analysed (known diagnoses; new diagnoses). RESULTS The risk for adverse pregnancy rises significantly in stage 1 CKD, when compared with controls: odds ratios were caesarean section 2.73 (1.72-4.33); preterm delivery 8.50 (4.11-17.57); NICU 16.10 (4.42-58.66). The risks rise in later stages. There is a high prevalence of new CKD diagnosis (overall: 38.6%; stage 1: 43.3%); no significant outcome difference was found across the referral patterns. Hypertension and proteinuria are confirmed as independent risk factors. CONCLUSIONS CKD is a risk factor in pregnancy; all patients should be followed within dedicated programmes from stage 1. There is need for dedicated interventions and educational programmes for maximizing the diagnostic and therapeutic potentials in early CKD stages.

Abstract
BACKGROUND Gestational hypertension and pre-eclampsia can cause fluid shifts. Pulmonary oedema and renal failure can result from these shifts. Fluid management is crucial in managing pre-eclampsia, especially in the context of pulmonary oedema and renal failure. Pulmonary artery catheterisation may be a method of effectively monitoring fluid status and thus aid in the management of renal failure and pulmonary oedema in the context of pre-eclampsia. OBJECTIVES To assess the safety and efficacy of pulmonary flow catheters in women with severe pre-eclampsia in preventing and managing of renal failure and pulmonary oedema or both. SEARCH METHODS We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (30 April 2012). SELECTION CRITERIA Randomised trials evaluating the use of the pulmonary artery catheterisation in the management of pre-eclamptic and eclamptic antepartum, intrapartum and postpartum women. DATA COLLECTION AND ANALYSIS We did not identify any randomised controlled studies. MAIN RESULTS There are no included studies. AUTHORS' CONCLUSIONS There is currently no evidence from randomised controlled trials supporting the use of the pulmonary artery catheters. Fluid management in pre-eclampsia, especially in the context of preventing or managing renal failure and pulmonary oedema, remains an important issue. Randomised trials dealing with this intervention are needed, however, we do recognise the difficulty in performing randomised trials due to the invasive nature of the procedure and skills involved in inserting a pulmonary flow catheter.

Abstract
Hypertension is the most common medical disorder encountered during pregnancy. Hypertensive disorders are one of the major causes of pregnancy-related maternal deaths in the United States. We will present a comprehensive update of the literature pertinent to hypertension in pregnancy. The paper begins by defining and classifying hypertensive disorders in pregnancy. The normal vascular and renal physiological changes which occur during pregnancy are detailed. We will summarize the intriguing aspects of pathophysiology of preeclampsia, emphasizing on recent advances in this field. The existing diagnostic tools and the tests which have been proposed for screening preeclampsia are comprehensively described. We also highlight the short- and long-term implications of preeclampsia. Finally, we review the current management guidelines, goals of treatment and describe the potential risks and benefits associated with various antihypertensive drug classes. Preeclampsia still remains an enigma, and the present management focuses on monitoring and treatment of its manifestations. We are hopeful that this in depth critique will stimulate the blossoming research in the field and assist practitioners to identify women at risk and more effectively treat affected individuals.

Abstract
Intrauterine growth restriction is associated with increased risk of adult cardiorenal diseases. Small birth weight females are more likely to experience complications during their own pregnancy, including pregnancy-induced hypertension, preeclampsia, and gestational diabetes. We determined whether the physiological demand of pregnancy predisposes growth-restricted females to cardiovascular and renal dysfunction later in life. Late gestation bilateral uterine vessel ligation was performed in Wistar-Kyoto rats. At 4 months, restricted and control female offspring were mated with normal males and delivered naturally (ex-pregnant). Regardless of maternal birth weight, at 13 months, ex-pregnant females developed elevated mean arterial pressure (indwelling tail-artery catheter; +6 mm Hg), reduced effective renal blood flow ((14)C-PAH clearance; -23%), and increased renal vascular resistance (+27%) compared with age-matched virgins. Glomerular filtration rate ((3)H-inulin clearance) was not different across groups. This adverse cardiorenal phenotype in ex-pregnant females was associated with elevated systemic (+57%) and altered intrarenal components of the renin-angiotensin system. After pregnancy at 13 months, coronary flow (Langendorff preparation) was halved in restricted females compared with controls, and together with reduced NO excretion, this may increase susceptibility to additional lifestyle challenges. Our results have implications for aging females who have been pregnant, suggesting long-term cardiovascular and renal alterations, with additional consequences for females who were small at birth.

Abstract
OBJECTIVES Women with a history of preeclampsia or gestational hypertension have an increased risk of cardiovascular disease. Underlying cardiovascular risk factors, persistent endothelial dysfunction or sympathetic overactivity may contribute to this risk. We studied markers of cardiovascular disease risk in nonpregnant women with a history of hypertension in pregnancy. METHODS Women with a history of preeclampsia (n = 39), gestational hypertension (n = 27) and normal pregnancies (n = 35) were studied 2-12 years after delivery. Laboratory measures included plasma fasting lipids, glucose, insulin, creatinine and urinary albumin-to-creatinine ratio. Blood pressure was measured by 24-h ambulatory blood pressure monitoring, endothelial function by flow-mediated dilatation and sympathetic activity by both head-up tilt test and cold pressor test, including the response of the circulating renin-angiotensin system to tilt testing. RESULTS Compared with women who had previous normal pregnancies, women with a history of preeclampsia or gestational hypertension have higher ambulatory blood pressure, BMI and relative insulin resistance. Glomerular filtration rate, albumin-to-creatinine ratio, endothelial function and sympathetic activity was similar among the three groups. CONCLUSION Women with a history of preeclampsia or gestational hypertension have features of the metabolic syndrome which are presumably present already before pregnancy, predisposing them to hypertensive disorders of pregnancy and later cardiovascular risk. In this study, we found no evidence for early renal damage, endothelial dysfunction or sympathetic overactivity in the postpartum state.

Abstract
The spectrum of kidney disease occurring during pregnancy includes preeclampsia, hypertensive disorders of pregnancy, urinary tract infection, acute kidney injury, and renal cortical necrosis (RCN). Preeclampsia affects approximately 3-5% of pregnancies. We observed preeclampsia in 5.8% of pregnancies, and 2.38% of our preeclamptic women developed eclampsia. Severe preeclampsia and the eclampsia or hemolysis, elevated liver enzymes levels, and low platelets count (HELLP) syndrome accounted for about 40% of cases of acute kidney injury (AKI) in pregnancy. Preeclampsia/eclampsia was the cause of acute renal failure (ARF) in 38.3% of the cases. Preeclampsia was the most common (91.7%) cause of hypertension during pregnancy, and chronic hypertension was present in 8.3% of patients. We observed urinary tract infection (UTI) in 9% of pregnancies. Sepsis resulting from pyelonephritis can progress to endotoxic shock, disseminated intravascular coagulation, and AKI. The incidence of premature delivery and low birth weight is higher in women with UTI. The incidence of AKI in pregnancy with respect to total ARF cases has decreased over the last 30 years from 25% in 1980s to 5% in 2000s. Septic abortion-related ARF decreased from 9% to 3%. Prevention of unwanted pregnancy and avoidance of septic abortion are key to eliminate abortion-associated ARF in early pregnancy. The two most common causes of ARF in third trimester and postpartum periods were puerperal sepsis and preeclampsia/HELLP syndrome. Pregnancy-associated thrombotic thrombocytopenic purpura/hemolytic uremic syndrome and acute fatty liver of pregnancy were rare causes of ARF. Despite decreasing incidence, AKI remains a serious complication during pregnancy.

Abstract
PURPOSE To investigate the characteristics of women who have kidney injury during pregnancy. METHODS Medical records of all women who gave birth at our institution between January 1, 2005, and December 31, 2010, were retrospectively reviewed electronically. We identified those who incurred a kidney injury [defined by modified Acute Kidney Injury Network (AKIN) criteria: serum creatinine (sCr) increase ≥0.3 mg/dL] during pregnancy or within 30 days postpartum. Identified case records were reviewed in detail. RESULTS During the study period, 54 women had a kidney injury (0.4 % estimated incidence) with a mean (SD) increase in sCr of 0.46 (0.29) mg/dL; most injuries were AKIN stage 1 with transient increases in sCr. Most of the women (n = 48, 87.3 %) had substantial preexisting or pregnancy-associated comorbid conditions (e.g., kidney disease, hypertension, diabetes), complications (e.g., preeclampsia, HELLP syndrome), or a complicated obstetric course (hemorrhage, infections) that could have contributed to the development of a kidney injury. Two patients had AKIN stage 3 injuries: a previously healthy patient who had a massive hemorrhage during cesarean delivery, and a patient with a renal transplant who had deterioration and eventual postpartum failure of her transplanted kidney. CONCLUSIONS The majority of pregnancy-associated kidney injuries were transient and occurred in women with substantial comorbid conditions or complicated pregnancies.

Abstract
Adverse exposures in utero have long been linked with an increased susceptibility to adult cardio-renal and metabolic diseases. Clear gender differences exist, whereby growth-restricted females, although exhibiting some phenotypic modifications, are often protected from overt disease outcomes. One of the greatest physiological challenges facing the female gender, however, is that of pregnancy; yet little research has focused on the outcomes associated with this, as a potential 'second-hit' for those who were small at birth. We review the limited evidence suggesting that pregnancy may unmask cardio-renal and metabolic disease states and the consequences for long-term maternal health in females who were born small. Additionally, a growing area of research in this programming field is in the transgenerational transmission of low birth weight and disease susceptibility. Pathways for transmission might include an abnormal adaptation to pregnancy by the growth-restricted mother and/or inheritance via the parental germline. Strategies to optimise the pregnancy environment and/or prevent the consequences of inheritance of programmed deficits and dysfunction are of critical importance for future generations.

Abstract
OBJECTIVE There are many kidney transplant recipients and living donors of reproductive age, and the prevalence of pregnancies in kidney transplant recipients can reach 55% in the Middle Eastern countries. Living kidney donation is predominant in this region. As the risks and outcomes of pregnancy should be a part of counselling for both recipients and donors, we reviewed available reports on maternal and foetal outcomes in these particular populations. METHODS Information was obtained from retrospective analyses of a large database, and from single-centre reports indexed in PubMed on pregnancy in donors and kidney transplant recipients. The keywords used for the search included 'fertility', 'kidney disease', 'pregnancy', 'maternal/foetal outcomes', 'kidney transplant recipient', 'immunosuppression side-effects', 'living donor' and 'Arab countries'. RESULTS Pregnancies in kidney transplant recipients are most successful in those with adequate kidney function and controlled comorbidities. Similarly to other regions, pregnant recipients in the Middle East had a higher risk of pre-eclampsia (26%) and gestational diabetes (7%) than in the general population. Caesarean section was quite common, with an incidence rate of 61%, and the incidence of pre-term birth reached 46%. CONCLUSIONS Most living donors can have successful pregnancies and should not be routinely discouraged. Women who had pregnancies before and after donation were more likely to have adverse maternal outcomes (gestational diabetes, hypertension, proteinuria, and pre-eclampsia) in the latter, but no adverse foetal outcomes were found after donation. The evaluation before donation should include a gestational history and counselling about the potential risks.

Abstract
Acute kidney injury (AKI) has been implicated as an independent risk factor for the development of CKD in recent observational studies. The presumption in the nephrology community is that this association represents a causal relationship. However, because of potential problems related to residual confounding (shared risk factors), ascertainment bias (sicker patients have more follow-up assessments), misclassification of exposure (problems with defining baseline kidney function and AKI representing a discrete event versus progression of renal disease), and misclassification of outcome (de novo CKD versus CKD progression), it is difficult to conclude with certainty that AKI is truly causal for CKD. In this review we highlight several of the Hill causality criteria to examine the existing evidence and point out the missing elements that preclude defining AKI as a cause of CKD in the general population. Only well-designed studies with rigorous assessment of kidney function in all participants (AKI and non-AKI) before and after the episode or hospitalization or randomized, controlled trials demonstrating that prevention or treatment of AKI reduces the incidence of subsequent CKD can clarify the causal nature of the AKI-CKD relationship.

Abstract
PURPOSE OF REVIEW Living kidney donors face a unique decision of self-sacrifice that is not without potential risk. The purpose of this review is to highlight existing research regarding the perioperative morbidity, mortality and long-term outcomes of living kidney donors. RECENT FINDINGS Recent studies of long-term donor survival have affirmed that the life expectancy for living kidney donors is excellent and their risk of end-stage renal disease (ESRD) is not increased. Long-term health outcomes for living donors representing minority groups, however, may not be as favorable. Recent studies conclude that African-American and Hispanic donors, similarly to nondonors of the same race, are at higher risk of developing chronic kidney disease (CKD), hypertension, and diabetes mellitus. Outcomes in medically complex donors have also generated considerable attention, and the evidence on outcomes among otherwise healthy obese and older donors appears to be reassuring. SUMMARY Living kidney donation is a superior transplantation option for many individuals with ESRD. The survival and health consequences of living donation have proven to be excellent. These favorable outcomes stem from careful screening measures, and further research endeavors are needed to ensure long-term living donor safety in high-risk donors.

Abstract
Excess soluble fms-like tyrosine kinase 1 (sFlt-1) of vascular endothelial growth factor receptor 1 secreted from the placenta causes pre-eclampsia-like features by antagonizing vascular endothelial growth factor signaling, which can lead to reduced endothelial nitric oxide synthase (eNOS) activity; the effect of this concomitant decrease in eNOS activity is unknown. We tested whether the decrease in nitric oxide occurring in female mice lacking eNOS aggravates the pre-eclampsia-like phenotype induced by increased sFlt-1. Untreated eNOS-deficient female mice had higher BP than wild-type mice. Adenovirus-mediated overexpression of sFlt-1 increased systolic BP by approximately 27 mmHg and led to severe loss of fenestration of glomerular capillary endothelial cells in both eNOS-deficient and wild-type mice. However, only the eNOS-deficient sFlt-1 mice exhibited severe foot process effacement. Compared with wild-type sFlt-1 mice, eNOS-deficient sFlt-1 mice also showed markedly higher urinary albumin excretion (467±74 versus 174±23 μg/d), lower creatinine clearance (126±29 versus 452±63 μl/min), and more severe endotheliosis. Expression of preproendothelin-1 (ET-1) and its ET(A) receptor in the kidney was higher in eNOS-deficient sFlt-1 mice than in wild-type sFlt-1 mice. Furthermore, the selective ET(A) receptor antagonist ambrisentan attenuated the increases in BP and urinary albumin excretion and ameliorated endotheliosis in both wild-type and eNOS-deficient sFlt-1 mice. Ambrisentan improved creatinine clearance and podocyte effacement in eNOS-deficient sFlt-1 mice. In conclusion, reduced maternal eNOS/nitric oxide exacerbates the sFlt1-related pre-eclampsia-like phenotype through activation of the endothelin system.

Abstract
BACKGROUND/AIMS Preeclampsia (PE) is a cause of glomerulopathy worldwide. Urinary retinol-binding protein (RBP) is a marker of proximal tubular dysfunction, albuminuria is an endothelial injury marker, urine protein:creatinine ratio (PCR) may have a predictive value for renal disease later in life, and, recently, podocyturia has been proposed as a sensitive tool in pregnancy, but it needs to be tested. The aim of this study was to evaluate renal involvement in PE and healthy pregnancy. METHODS Case-control study with 39 pregnant women assessed after 20 weeks of gestation (25 in the control group, CG, and 14 in the PE group) by performing urinary tests. RESULTS Mean (±SD) age and gestational age of the CG were 26.9 ± 6.4 years and 37.1 ± 5.0 weeks, and of the PE group 26.4 ± 6.9 years and 30.6 ± 5.6 weeks, respectively (p = 0.001). Mean (±SD) urinary RBP (p = 0.017), albuminuria (p = 0.002), and urinary albumin concentration (UAC) ratio (p = 0.006) of the CG were 0.4 ± 0.7 mg/l, 7.3 ± 6.9 mg/l, and 8.2 ± 6.7 mg/g and of the PE group 2.0 ± 4.4 mg/l, 2,267.4 ± 2,130.8 mg/l (p = 0.002), and 3,778.9 ± 4,296.6 mg/g (p = 0.006), respectively. Mean (±SD) urine PCR in the PE group was 6.7 ± 6.1 g/g (p < 0.001). No statistical differences were found between podocyturia in the CG and PE group (p = 0.258). CONCLUSIONS Urinary RBP, PCR, albuminuria, and UAC ratio were elevated in the PE group in comparison to the CG. Podocyturia did not predict PE.

Abstract
This study examined the effect of over-expression of sFlt-1 by trophoblasts on the barrier function of glomerular endothelial cells and the role of VEGF in this process in order to explore the pathogenesis of glomerular disease in preeclampsia. SFlt-1 expression in the human trophoblasts (TEV-1 cells) was enhanced by transfecting sFlt-1 plasmid DNA into TEV-1 cells. The monolayer barrier function of glomerular endothelial cells (ciGEnCs) was determined by measuring the fluorescence intensity of bovine serum albumin (BSA) that crossed the monolayer of glomerular endothelial cells. The results showed that the over-expression of sFlt-1 by TEV-1 cells led to the barrier dysfunction of ciGEnCs, and the exogenous VEGF could alleviate the ciGEnCs dysfunction resulting from the over-expression of sFlt-1 to a certain extent. It was concluded that the dysregulation of sFlt-1 and VEGF in preeclamptic pregnancy may contribute to the barrier dysfunction of glomerular endothelial cells, and VEGF may play an important role in maintaining the barrier function of glomerular endothelial cells, but it may not be the sole factor.

Abstract
OBJECTIVE Pre-eclampsia contributes significantly to maternal, foetal and neonatal morbidity and mortality. The risk factors for pre-eclampsia have not been well documented in Uganda. In this paper, we describe the risk factors for pre-eclampsia in women attending antenatal clinics at Mulago Hospital, Kampala. METHODS This casecontrol study was conducted from 1st May 2008 to 1st May 2009. 207 women with pre-eclampsia were the cases, and 352 women with normal pregnancy were the controls. The women were 15-39 years old, and their gestational ages were 20 weeks or more. They were interviewed about their socio-demographic characteristics, past medical history and, their past and present obstetric performances. RESULTS The risk factors were low plasma vitamin C (OR 3.19, 95% CI: 1.54-6.61), low education level (OR 1.67, 95% CI: 1.12-2.48), chronic hypertension (OR 2.29, 95% CI 1.12-4.66), family history of hypertension (OR 2.25, 95% CI: 1.53-3.31) and primiparity (OR 2.76, 95% CI: 1.84-4.15) and para≥5 (3.71, 95% CI:1.84-7.45). CONCLUSION The risk factors identified are similar to what has been found elsewhere. Health workers need to identify women at risk of pre-eclampsia and manage them appropriately so as to prevent the maternal and neonatal morbidity and mortality associated with this condition.

Abstract
Hypertension is a common complication of pregnancy. Preeclampsia, in particular, is associated with substantial risk to both the mother and the fetus. Several risk factors have been recognized to predict risk for preeclampsia. However, at present no biomarkers have sufficient discriminatory ability to be useful in clinical practice, and no effective preventive strategies have yet been identified. Commonly used medications for the treatment of hypertension in pregnancy include methyldopa and labetalol. Blood pressure thresholds for initiating antihypertensive therapy are higher than outside of pregnancy. Women with prior preeclampsia are at increased risk of hypertension, cardiovascular disease, and renal disease.

Abstract
Pregnancy places increased demands on the mother to provide adequate nutrition to the growing conceptus. A number of micronutrients function as essential cofactors for or themselves acting as antioxidants. Oxidative stress is generated during normal placental development; however, when supply of antioxidant micronutrients is limited, exaggerated oxidative stress within both the placenta and maternal circulation occurs, resulting in adverse pregnancy outcomes. The present paper summarises the current understanding of selected micronutrient antioxidants selenium, copper, zinc, manganese, and vitamins C and E in pregnancy. To summarise antioxidant activity of selenium is via its incorporation into the glutathione peroxidase enzymes, levels of which have been shown to be reduced in miscarriage and preeclampsia. Copper, zinc, and manganese are all essential cofactors for superoxide dismutases, which has reduced activity in pathological pregnancy. Larger intervention trials are required to reinforce or refute a beneficial role of micronutrient supplementation in disorders of pregnancies.

Abstract
In primates, adequate growth of the fetus depends on the development of the uteroplacental unit. On the fetal side, this is achieved by the creation of the vascular network of the placenta. On the maternal side, the transformation of the spiral arteries into saccular nonreactive vessels by the trophoblast provides high blood flow to the intervillous space. Apart from the changes in the uterine arteries, the mother expands her plasma volume – at the expense of stimulating the renin-angiotensin-aldosterone system – and her cardiac output. In the maintaining of normotension in the face of an increased cardiac output and plasma volume, the renin-angiotensin-aldosterone system requires an enhanced vasodilator synthesis. Finally, in the late stages of pregnancy, a normal endothelial function is required to provide an ample margin to the activation provoked by deportation of syncytiotrophoblast fragments/factors to the maternal circulation. These four adaptative processes require various interrelated vasodilator systems. Deficient adaptations cause isolated or proteinuric arterial hypertension, intrauterine growth restriction, preterm delivery, and stillbirths, among others. Moreover, a normal or a defective adaptation to pregnancy influences maternal cardiovascular health in later life, as evidenced by various studies, most of them epidemiological; thus, pregnancy is now considered a stress test to the maternal cardiovascular system. Because of this, women planning to become pregnant should be screened for clinical and biochemical cardiovascular risks. Inversely, women presenting with hypertension in pregnancy should be thoroughly studied to detect and correct cardiovascular risks. The incorporation of the predictive value of a hypertensive pregnancy should help reduce cardiovascular disease in women.

Abstract
The occurrence of pregnancy in patients with chronic kidney disease (CKD) has been considered a dangerous event both for the mother and for the fetus. However, increasing evidence shows that the stage of CKD is the leading factor that can predict possible acceleration in the declining of renal function and complications of pregnancy. This review summarizes recent data on pregnancy in patients with CKD, dialysis and kidney transplantation.

Abstract
The prevalence of diabetes in pregnant women is increasing, with 4% of deliveries in the United States occurring in women with pregestational or gestational diabetes. The proteinuria of late pregnancy is exaggerated in women with diabetes. However, diabetic women with preserved renal function before pregnancy appear to have little risk of deterioration of kidney function during pregnancy. Women with impaired renal function before pregnancy may be at risk for permanent decline of renal function during pregnancy, although it is unclear whether this represents the effect of pregnancy or the natural history of their diabetic renal disease. Preeclampsia, which is more common in women with diabetes, may be difficult to diagnose in this group of women. From the currently available literature, there appears to be no negative effect of pregnancy on the long-term progression of diabetic renal disease if renal function is normal and marked proteinuria is absent, but in light of recent findings in which preeclampsia appears to be associated with an increased risk of end-stage renal disease, large cohort studies will be necessary before this question can be definitively answered.

Abstract
Hypertension, proteinuria and biochemical changes caused by pre-eclampsia may persist for several weeks and even months postpartum. Hypertension and pre-eclampsia may even develop for the first time postpartum. Care in the six weeks postpartum should include management of hypertension and screening for secondary causes of hypertension including renal disease if abnormalities persist beyond six weeks. Optimal postpartum monitoring for patients with preeclampsia has not been determined, and care needs to be individualized. The postpartum period also provides a window of opportunity for planning for the next pregnancy in addition to discussing long term implications of pre-eclampsia. Increased risk for the development of premature cardiovascular disease is the most significant long term implication of pre-eclampsia. Pre-eclampsia and cardiovascular disease share a common disease pathophysiology. Women who develop pre-eclampsia have pre-existing metabolic abnormalities or may develop them later in life. Women with early onset pre-eclampsia are at the highest risk of ischemic heart disease. Women with a history of pre-eclampsia should adopt a heart healthy lifestyle and should be screened and treated for traditional cardiovascular risk factors according to locally accepted guidelines.

Abstract
PURPOSE As a noninvasive examination, urinary proteomics is a very useful tool to identify renal disease. The purpose of the present study was to find differential proteins among women with preeclampsia, gestational hypertension and normal pregnancy, and to screen potential biomarkers for the early diagnosis of preeclampsia. EXPERIMENTAL DESIGN Urinary proteins were identified by iTRAQ labeling coupled with 2-D LC-MS/MS. The bioinformatics analysis was performed with the Metacore software and the International Protein Index (IPI) and the Gene Ontology (GO) Database. The differentially expressed proteins were verified by ELISA. RESULTS 362 nonredundant proteins were identified, 113 of which were expressed differentially between preeclampsia and normal pregnant group and 31 differential proteins among three groups. These differential proteins were associated with biological processes of blood coagulation, cell adhesion and differentiation, immune response and cytoskeleton development, etc. They interacted with each other in the network. The urinary angiotensinogen (AGT) was downregulated, which was consistent with the ELISA validation results. CONCLUSIONS AND CLINICAL RELEVANCE The present study found a multitude of differential proteins that might provide a clue for investigating the mechanism of proteinuria development in preeclampsia. Low urinary angiotensinogen levels were useful for identifying preeclampsia.

Abstract
The gestational period serves as a natural stress test that can be used to predict future cardiovascular health risks of female patients. Recent evidence confirms that mothers with hypertensive pregnancies have higher cardiovascular disease (CVD) risks compared to other women of similar age. In women with preeclampsia, those delivering before 37 weeks of gestation and mothers with recurring preeclampsia in subsequent pregnancies carry the greater risks. These sex-specific risks are of similar magnitude to traditional CVD risk factors, such as smoking and obesity. Unfortunately, none of the commonly used CVD risk stratification models make use of these sex-specific markers, which can powerfully predict future CVD outcomes. Because women have historically posed a greater diagnostic challenge than men in assessing CVD risks, better models for risk stratification in this sex group are needed. A history of hypertension in pregnancy should be included as a variable in cardiovascular risk stratification. In addition, screening women for a history of preeclampsia should become routine practice, with greater emphasis placed on therapies to modify adverse outcomes for these higher-risk women.

Abstract
OBJECTIVE Preeclampsia, a hypertensive disorder of pregnancy, affects 5-8% of women. Large studies demonstrate a strong association between preeclampsia and future cardiovascular disease (CVD). Despite CVD being the leading cause of mortality for women, there has been little education for internal medicine physicians or obstetrician-gynecologists (ob-gyns) about this association; published guidelines do not include preeclampsia as a risk factor for future CVD. Therefore, women with a history of preeclampsia may not receive adequate risk-reduction counseling for CVD. It is unclear whether primary care physicians are aware of the association; thus, we sought to determine whether primary care providers at our institution were aware of preeclampsia's association with future CVD and whether they were providing appropriate counseling. METHODS An anonymous online survey was sent to all internists and (ob-gyns) at our hospital. RESULTS Although most internists (95%) and (ob-gyns) (70%) provide routine cardiovascular risk-reduction counseling, a substantial proportion of them were unaware of any health risk associated with a history of preeclampsia. Many internists were unsure or did not know whether preeclampsia is associated with ischemic heart disease (56%), stroke (48%), and decreased life expectancy (79%). The corresponding proportions for (ob-gyns) were 23, 38, and 77%, respectively. Only 9% of internists and 38% of obstetrician-gynecologists were providing cardiovascular risk-reduction counseling to women with a history of preeclampsia. CONCLUSION There is limited knowledge of the association between preeclampsia and future CVD; this deficiency may limit the application of this risk factor to clinical care.
