Abstract
AIM IgA nephropathy (IgAN) is the most common primary glomerular disease worldwide. Pregnant IgAN patients are more susceptible to adverse pregnancy outcomes (APO). However, the risk factor for APO and its effects on the long-term renal outcome of pregnant IgAN patients remained unclear. METHODS We performed a retrospective observational study covering 2003-2019 that included 44 female IgAN patients with pregnancy history to investigate the risk factor for APO and its impact on clinical outcome in IgAN. Renal function outcome and proteinuria remission were evaluated in pregnant IgAN women with and without APO. RESULTS In this retrospective and observational study, we found that patients with APO exhibited higher levels of serum creatinine and IgM, and lower haemoglobin levels while other clinical characteristics, pathological characteristics and therapy protocol had no significant difference. We found that anaemia and a higher level of serum IgM were independent risk factors for APO. IgAN pregnant women without APO experienced a higher proportion of proteinuria remission than those with APO, but there is no difference in the renal function outcome. CONCLUSION Pregnant IgAN patients with higher risks, including lower haemoglobin levels and higher IgM levels deserve intensive monitoring, and aggressive therapy to reduce proteinuria should be carried out in pregnant IgAN patients with APO.

Koirala P, Garovic V, Irene Dato M, Kattah A. Role of chronic kidney disease and risk factors in preeclampsia. Pregnancy Hypertens 2024; 37:101146. [PMID: 39159547 DOI: 10.1016/j.preghy.2024.101146] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/03/2024] [Revised: 06/30/2024] [Accepted: 08/10/2024] [Indexed: 08/21/2024]
Abstract
BACKGROUND Our goal was to identify what impact chronic kidney disease (CKD) and its associated risk factors, such as body mass index (BMI), diabetes and hypertension, have on preeclampsia and other adverse pregnancy outcomes in the CKD population. METHODS This was a population-based cohort study of women with CKD who had a pregnancy from 2010 to 2022 (n = 95). At the time of the woman's pregnancy, data was collected on demographics, clinical measures, BMI, CKD etiology and other renal parameters. Outcomes included preeclampsia, pre-term delivery, and low birth weight. RESULTS Pre-pregnancy BMI increased over time in patients with CKD, with a median (interquartile range) BMI of 25 (22-29) prior to 2016 and 29 (25-34) after 2016 (p = 0.01). There were significant trends of increasing age at delivery and decreasing pre-pregnancy estimated glomerular filtration rate (eGFR) by delivery year. Preeclampsia affected nearly half of pregnancies in this cohort. In multivariate analyses, BMI and chronic hypertension did not impact the odds of preeclampsia, preterm delivery or low birth weight, though a CKD etiology of diabetes (19/20 with type I diabetes), was associated with a significant increase in preeclampsia risk (odds ratio (OR) 7.41 (95 % CI 2.1-26.1)). Higher pre-pregnancy eGFR was associated with a lower odds of preterm delivery (OR 0.81 (95 % CI 0.67-0.98)) per 10 ml/min/1.73 m2). CONCLUSION Pre-pregnancy BMI significantly increased over time, similar to the general population. While preeclampsia was common in CKD patients, outcomes were associated with eGFR and CKD etiology as opposed to BMI and chronic hypertension.

Abstract
INTRODUCTION Hypertensive disorders of pregnancy affect approximately one in 10 pregnancies and are associated with increased risk of adverse fetal, neonatal and maternal outcomes. There is strong evidence that effective treatment of hypertension (blood pressure ≥ 140/90 mmHg), and enhanced monitoring throughout pregnancy reduces these risks. AREAS COVERED This article provides a contemporaneous review of treatment of hypertension in pregnancy with antihypertensive agents. We completed a systematic search and review of all meta-analyses and systematic reviews of studies comparing antihypertensives for treatment of pregnancy hypertension in the last five years. We provide a clinically focused summary of when to treat hypertension in pregnancy and which antihypertensive agents can be offered. Special scenarios reviewed include treatment-resistant hypertension and pre-pregnancy antihypertensive optimization. EXPERT OPINION Several antihypertensives are considered safe and are known to be effective for treatment of hypertension in pregnancy. Given the current uncertainty as to which antihypertensive(s) are superior for treatment of hypertension in pregnancy, women should be counselled and offered a range of antihypertensive options in keeping with evidence on clinical effectiveness, local context and availability of antihypertensive(s), potential side effect profile, and women's preference. Further research is required to help guide clinical decision making, and move toward personalized treatment.

Abstract
Monitoring and timing of delivery in preterm preeclampsia and fetal growth restriction is one of the biggest challenges in Obstetrics. Finding the optimal time of delivery of these fetuses usually involves a trade-off between the severity of the disease and prematurity. So far, most clinical guidelines recommend the use of a combination between clinical, laboratory and ultrasound markers to guide the time of delivery. Angiogenic biomarkers, especially placental growth factor (PlGF) and soluble fms-like tyrosine kinase-1 (sFlt-1), have gained significant attention in recent years for their potential role in the prediction and diagnosis of placenta-related disorders including preeclampsia and fetal growth restriction. Another potential clinical application of the angiogenic biomarkers is for the differential diagnosis of patients with chronic kidney disease, as this condition shares similar clinical features with preeclampsia. Consequently, angiogenic biomarkers have been advocated as tools for monitoring and deciding the optimal time of the delivery of fetuses affected by placental dysfunction. In this clinical opinion, we critically review the available literature on PlGF and sFlt-1 for the surveillance and time of the delivery in fetuses affected by preterm preeclampsia and fetal growth restriction. Moreover, we explore the use of angiogenic biomarkers for the differentiation between chronic kidney disease and superimposed preeclampsia.

Abstract
Chronic kidney disease (CKD) presents significant challenges in the management of pregnant women due to its impact on renal function and cardiovascular stability. This review examines the crucial role of anesthesia management in antenatal care for women with CKD, focusing on the complexities introduced by renal dysfunction and the implications for maternal and fetal health outcomes. The review discusses the physiological changes in CKD during pregnancy, highlighting the increased risks of hypertension, proteinuria, and adverse fetal outcomes. Anesthesia considerations, including the choice of anesthesia techniques (general anesthesia, regional anesthesia), perioperative monitoring, and management of fluid and electrolyte balance, are analyzed in the context of CKD-specific challenges. Clinical outcomes and current evidence regarding anesthesia efficacy and safety in CKD patients are reviewed, emphasizing the need for tailored anesthesia protocols to ensure optimal maternal comfort and fetal safety. The review concludes by identifying research gaps and proposing future directions to enhance anesthesia practices and improve outcomes for pregnant women with CKD undergoing surgical interventions or labor management.

Abstract
A 37-year-old woman with chronic kidney disease (CKD) stage G4 with membranoproliferative glomerulonephritis was hospitalized for nephrotic syndrome and hypertension due to superimposed preeclampsia at 27 weeks into her third pregnancy. Proteinuria did not worsen significantly after pulse steroid therapy. Delivery was induced at 30 weeks' gestation due to the maternal renal function and fetal growth. No obvious fetal complications other than preterm delivery were observed. In this case, we successfully managed a high-risk patient with membranoproliferative glomerulonephritis complicated by advanced CKD, nephrotic syndrome, and hypertension, which are independent risk factors for pregnancy complications.

Abstract
The sFlt-1/PlGF ratio is an established tool in clinical practice, where it is part of a diagnostic algorithm and informs the prognosis of preeclampsia (PE). Maternal and gestational comorbidities can affect the performance of the sFlt-1/PlGF ratio and its constituent elements, and a good understanding of the potential pitfalls is required. The objective of this paper was to provide a current narrative review of the literature on the diagnostic and predictive performance of the sFlt-1/PlGF ratio in specific patient cohorts. Potential factors which can negatively affect the clinical interpretability and applicability of the sFlt-1/PlGF ratio include chronic kidney disease, twin pregnancy, and maternal obesity. Pathophysiological mechanisms related to these factors and disorders can result in different concentrations of sFlt-1 and/or PlGF in maternal blood, meaning that the use of standard cut-off values in specific cohorts can lead to errors. To what extent the cut-off values should be adapted in certain patient cohorts can only be clarified in large prospective cohort studies. This applies to the use of the ratio both for diagnosis and prognosis.

Abstract
Introduction Females with kidney disease are at increased risk for pregnancy complications. Few studies have examined pregnancy perspectives of people with kidney disease. Our objective was to examine kidney patients' perspectives on family planning. Methods We conducted an online survey of female patients with kidney disease from the University of Colorado Hospital between the ages of 18 and 50 years from August to October 2022. The survey asked questions on previous and current pregnancies with kidney disease, family planning, and reproductive health discussions with their nephrologists. Perspectives on how kidney disease influences pregnancies were also explored. Results A total of 136 participants completed the survey. The majority of participants were White (71.3%) with a mean (SD) age of 37 ± 10 years. The majority of participants self-characterized their kidney disease as moderate (n = 57, 43.5%) with 16 participants (12.2%) receiving dialysis. Fifty-two participants (38.5%) experienced a pregnancy with a diagnosis of kidney disease, which were largely planned (n = 33, 61.1%). The majority of participants were able to conceive within 6 months (64.8%). Nearly half of participants reported that kidney disease influenced their family planning decisions with the majority (n = 91, 66.5%) believing that kidney disease increased their risk for pregnancy complications. More than half of participants never discussed the health risks of a potential pregnancy (54.0%), desire to have children (58.0%), pregnancy prevention (57.0%), and/or optimizing their health prior to pregnancy (68.1%) with their nephrologist. Conclusion Although kidney disease influenced family planning decisions, few participants had family planning discussions with their nephrologists.

Abstract
Pregnancy in women living with chronic kidney disease (CKD) was often discouraged due to the risk of adverse maternal-fetal outcomes and the progression of kidney disease. This negative attitude has changed in recent years, with greater emphasis on patient empowerment than on the imperative 'non nocere'. Although risks persist, pregnancy outcomes even in advanced CKD have significantly improved, for both the mother and the newborn. Adequate counselling can help to minimize risks and support a more conscious and informed approach to those risks that are unavoidable. Pre-conception counselling enables a woman to plan the most appropriate moment for her to try to become pregnant. Counselling is context sensitive and needs to be discussed also within an ethical framework. Classically, counselling is more focused on risks than on the probability of a successful outcome. 'Positive counselling', highlighting also the chances of a favourable outcome, can help to strengthen the patient-physician relationship, which is a powerful means of optimizing adherence and compliance. Since, due to the heterogeneity of CKD, giving exact figures in single cases is difficult and may even be impossible, a scenario-based approach may help understanding and facing favourable outcomes and adverse events. Pregnancy outcomes modulate the future life of the mother and of her baby; hence the concept of 'post partum' counselling is also introduced, discussing how pregnancy results may modulate the long-term prognosis of the mother and the child and the future pregnancies.

Abstract
Chronic kidney disease (CKD), anemia, and iron deficiency are global health issues affecting individuals in both high-income and low-income countries. In pregnancy, both CKD and iron deficiency anemia increase the risk of adverse maternal and neonatal outcomes, including increased maternal morbidity and mortality, stillbirth, perinatal death, preterm birth, and low birthweight. However, it is unknown to which extent iron deficiency anemia contributes to adverse outcomes in CKD pregnancy. Furthermore, little is known regarding the prevalence, pathophysiology, and treatment of iron deficiency and anemia in pregnant women with CKD. Therefore, there are many unanswered questions regarding optimal management with oral or i.v. iron and recombinant human erythropoietin (rhEPO) in these women. In this review, we present a short overview of the (patho)physiology of anemia in healthy pregnancy and in people living with CKD. We present an evaluation of the literature on iron deficiency, anemia, and nutritional deficits in pregnant women with CKD; and we evaluate current knowledge gaps. Finally, we propose research priorities regarding anemia in pregnant women with CKD.

Any reduction in maternal kidney mass makes a difference during pregnancy in gestational and fetal outcome. Kidney Int 2024; 105:865-876. [PMID: 38296027 DOI: 10.1016/j.kint.2023.12.018] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/28/2023] [Revised: 11/29/2023] [Accepted: 12/15/2023] [Indexed: 02/19/2024]
Abstract
Little is known about the effect tubulointerstitial nephropathies have in modulating maternal-fetal outcomes in pregnancy. Therefore, we analyzed the main outcomes of pregnancy in these women to gain a better understanding of the role of a reduction in maternal kidney mass. From the Torino Cagliari Observational Study (TOCOS) cohort, we selected 529 patients with a diagnosis of tubulointerstitial disease and focused on 421 patients with chronic kidney disease (CKD) stage 1, without hypertension but with proteinuria less than 0.5 g/day at referral. From a cohort of 2969 singleton deliveries from low-risk pregnancies followed in the same settings we selected a propensity score matched control cohort of 842 pregnancies match 2:1 for age, parity, body mass index, ethnicity, and origin. Time to delivery was significantly shorter in the study cohort 38.0 (Quartile 1-Quartile 3: 37.0-39.0) versus 39.0 (Q1-Q3 38.0-40.0) weeks, with respect to controls. Incidence of delivery of less than 37 gestational weeks significantly increased from controls (7.4%) to women with previous acute pyelonephritis (10.8%), other tubulointerstitial diseases (9.7%) and was the highest in patients with a single kidney (31.1%). Similarly, neonatal birthweight significantly and progressively decreased from controls (3260 g [Q1-Q3: 2980-3530]), previous acute pyelonephritis (3090 g [Q1-Q3: 2868-3405], other tubulointerstitial diseases (3110 g [Q1-Q3: 2840-3417]), and to solitary kidney (2910 g [Q1-Q3: 2480-3240]). Risk of developing preeclampsia was significantly higher in the CKD cohort (3.6% vs 1.7% in low-risk controls). Thus, even a small reduction in functional kidney mass, such as a pyelonephritic scar, is associated with a shorter duration of pregnancy and an increased risk of preterm delivery. The risk is proportional to the extent of parenchymal reduction and is highest in cases with a solitary kidney.

Abstract
Proteinuria during pregnancy is closely related to the occurrence of adverse pregnancy outcomes. One hundred and forty-two women with proteinuria during pregnancy and followed between January 2018 and December 2020 were evaluated. Based on the 24-h proteinuria value, they were divided as mild (n = 76, 300-1000 mg/day), moderate (n = 39, 1000-3500 mg/day) and severe (n = 27, >3500 mg/day) proteinuria. The rates of prematurity, low birth weight and neonatal asphyxia were significantly higher in the severe proteinuria group than in the mild and moderate groups, while the rates of foetal growth restriction and neonatal intensive care unit admission were significantly higher in the severe compared with the mild proteinuria group (all p < .05). Logistic regression analysis showed that moderate proteinuria (OR = 97.2, 95%CI: 7.1-1334.2, p = .001) and severe proteinuria (OR = 34.0, 95%CI: 1.6-711.0, p = .023) were associated with adverse perinatal outcomes. Compared with mild proteinuria, moderate and severe proteinuria are associated with adverse pregnancy outcomes in perinatal infants.Impact StatementWhat is already known on this subject? The production of proteinuria is closely related to the filtration function of the glomerulus, the reabsorption and secretion function of the renal tubules. For women with normal renal function before pregnancy, such physiological changes are less likely to cause adverse symptoms; however, for women with chronic kidney disease before pregnancy, especially those with significantly impaired renal function, the kidneys often cannot compensate for these physiological changes, which can lead to serious complications for both mother and infant.What do the results of this study add? In our study, logistic regression analysis showed that the severity of proteinuria was independently associated with adverse perinatal outcomes. The ROC curve showed that 24-h proteinuria had a predictive value for adverse perinatal outcomes. Therefore, for patients with urine protein quantification ≥0.3 g/24 h, regular 24-h urine protein quantification during pregnancy could help predict adverse perinatal outcomes and improve prognosis.What are the implications of these findings for clinical practice and/or further research? Proteinuria quantification can be used as one of the factors predicting adverse pregnancy outcomes. Thus, monitoring of urinary protein quantification in women during pregnancy should be strengthened for early detection of renal impairment, then interventions be used to improve maternal and infant outcomes.

Abstract
Background Proteinuria is commonly measured to assess the renal status of chronic kidney disease (CKD) patients before the 20th week of gestation during pregnancy. High levels of proteiuria have been associated with adverse pregnancy outcomes. However, researchers have not clearly determined what baseline proteinuria levels would be associated with adverse pregnancy outcomes. This study aimed to analyse associations between proteinuria levels and adverse pregnancy outcomes among CKD patients treated with or without steroids/immunosuppressive therapy in early pregnancy. Methods This retrospective study included the clinical information of 557 pregnant patients with CKD from 1 January 2009 to 31 December 2021. A multivariable logistic regression analysis was conducted to evaluate the risk of adverse pregnancy outcomes across various proteinuria ranges, which were further stratified by whether the patients were receiving steroids/immunosuppressive therapy. Results (i) Proteinuria was assessed on 24-h urine collection. The median (quartile) baseline proteinuria levels were 0.83 g (0.20, 1.92) and 0.25 g (0.06, 0.80) in the steroids/immunosuppressive therapy and therapy-free groups, respectively. (ii) CKD patients with adverse pregnancy outcomes had significantly higher proteinuria levels in the first trimester than patients without adverse pregnancy outcomes. (iii) The risk of adverse pregnancy outcomes increased with increasing baseline proteinuria levels (P < .001). (iv) In the early-pregnancy steroids/immunosuppressive therapy group, the risk of severe preeclampsia was higher in patients with higher baseline proteinuria levels (P < .007) [odds ratio (OR) 30.86 for proteinuria ≥5.00 g/24 h]; in the therapy-free group, the risks of severe preeclampsia, very-low-birth-weight infants, early preterm birth and foetal-neonatal death were higher in patients with higher baseline proteinuria levels (OR 53.16 for proteinuria ≥5.00 g/24 h; OR 37.83 for proteinuria ≥5.00 g/24 h; OR 15.30 for proteinuria ≥5.00 g/24 h; and OR 18.83 for proteinuria ≥5.00 g/24 h, respectively; P < .001, P < .001, P < .001 and P = .006, respectively). Conclusions As shown in the present study, a baseline 24-h proteinuria level >1.00 g was associated with adverse maternal outcomes. Furthermore, a 24-h proteinuria level >2.00 g increased the incidence of adverse foetal events among CKD patients.

Abstract
Purpose of review To review the current studies and guidelines on the risk of adverse pregnancy outcomes in female kidney donors. Recent findings Living kidney donors include a significant amount of young women of child-bearing age. Safety and possible risks of pregnancy after donation are a concern for female kidney donor candidates. Many current studies indicate a higher risk of preeclampsia in women after kidney donation. Considering the increasing number of living kidney donors, the maternal outcomes of living kidney donation is an active area of research. Summary Guidelines and consensus statements on the risk of pregnancy in living kidney donors recommend close monitoring of blood pressure, weight gain, and proteinuria during pregnancy. Current studies indicate an increased risk of hypertensive disorders of pregnancy in living kidney donors. Counseling and informing donor candidates about the possible risks is important.

Abstract
INTRODUCTION Women with Chronic Kidney Disease (CKD) are at increased risk of adverse pregnancy and renal outcomes. It is unknown how women with CKD understand their pregnancy risk. This nine-centre, cross-sectional study aimed to explore how women with CKD perceive their pregnancy risk and its impact on pregnancy intention, and identify associations between biopsychosocial factors and perception of pregnancy risk and intention. METHODS Women with CKD in the UK completed an online survey measuring their pregnancy preferences; perceived CKD severity; perception of pregnancy risk; pregnancy intention; distress; social support; illness perceptions and quality of life. Clinical data were extracted from local databases. Multivariable regression analyses were performed. Trial registration: NCT04370769. RESULTS Three hundred fifteen women participated, with a median estimated glomerular filtration rate (eGFR) of 64 ml/min/1.73m2 (IQR 56). Pregnancy was important or very important in 234 (74%) women. Only 108 (34%) had attended pre-pregnancy counselling. After adjustment, there was no association between clinical characteristics and women's perceived pregnancy risk nor pregnancy intention. Women's perceived severity of their CKD and attending pre-pregnancy counselling were independent predictors of perceived pregnancy risk. Importance of pregnancy was an independent predictor of pregnancy intention but there was no correlation between perceived pregnancy risk and pregnancy intention (r = - 0.002, 95% CI - 0.12 to 0.11). DISCUSSION Known clinical predictors of pregnancy risk for women with CKD were not associated with women's perceived pregnancy risk nor pregnancy intention. Importance of pregnancy in women with CKD is high, and influences pregnancy intention, whereas perception of pregnancy risk does not.

Abstract
INTRODUCTION Women of reproductive age with chronic kidney disease (CKD) are recognised to have decreased fertility and a higher risk of adverse pregnancy outcomes. How often CKD afflicts women of reproductive age is not well known. This study aimed to evaluate the burden of CKD and associated birth rates in an entire region. METHODS This was a retrospective cohort study including women of childbearing age in Stockholm during 2006-2015. We estimated the prevalence of "probable CKD" by the presence of an ICD-10 diagnosis of CKD, a single estimated glomerular filtration rate (eGFR) < 60 mL/min/1.73 m2 or history of maintenance dialysis. By linkage with the Swedish Medical Birth Register we identified births during the subsequent three years from study inclusion and evaluated birth rates. RESULTS We identified 817,730 women in our region, of whom 55% had at least one creatinine measurement. A total of 3938 women were identified as having probable CKD, providing an age-averaged CKD prevalence of 0.50%. Women with probable CKD showed a lower birth rate 3 years after the index date (35.7 children per 1000 person years) than the remaining women free from CKD (46.5 children per 1000 person years). CONCLUSION As many as 0.50% of individuals in this cohort had probable CKD, defined on the basis of at least one eGFR<60 ml/min1.73 m2 test result, dialysis treatment (i.e. CKD stages 3-5) or an ICD-10 diagnosis of CKD. This prevalence is lower than previous estimates. Women with probable CKD, according to a study mainly capturing CKD 3-5, had a lower birth rate than those without CKD, illustrating the challenges of this population to successfully conceive.

Abstract
Preeclampsia (PE) is a multisystem obstetric disorder that affects 2-10% of pregnancies worldwide and it is a leading cause of maternal and fetal morbidity and mortality. The etiology of PE development is not clearly delineated, but since delivery of the fetus and placenta often leads to symptom resolution in the most cases of PE, it is hypothesized that the placenta is the inciting factor of the disease. Current management strategies for PE focus on treating the maternal symptoms to stabilize the mother in an attempt to prolong the pregnancy. However, the efficacy of this management strategy is limited. Therefore, identification of novel therapeutic targets and strategies is needed. Here, we provide a comprehensive overview of the current state of knowledge regarding mechanisms of vascular and renal pathophysiology during PE and discuss potential therapeutic targets directed at improving maternal vascular and renal function.

Abstract
Our understanding of the various aspects of pregnancy in women with kidney diseases has significantly improved in the last decades. Nevertheless, little is known about specific kidney diseases. Glomerular diseases are not only a frequent cause of chronic kidney disease in young women, but combine many challenges in pregnancy: immunologic diseases, hypertension, proteinuria, and kidney tissue damage. An international working group undertook the review of available current literature and elicited expert opinions on glomerular diseases in pregnancy with the aim to provide pragmatic information for nephrologists according to the present state-of-the-art knowledge. This work also highlights areas of clinical uncertainty and emphasizes the need for further collaborative studies to improve maternal and fetal health.

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.

Efficacy and safety of hemodialysis strategies for pregnant women with chronic kidney disease: Systematic review. Semin Dial 2023; 36:3-11. [PMID: 35934871 DOI: 10.1111/sdi.13120] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/28/2022] [Revised: 06/28/2022] [Accepted: 07/10/2022] [Indexed: 02/01/2023]
Abstract
Pregnancy in chronic kidney disease (CKD) women is relatively rare, and the less risky choice of hemodialysis is unknown. The objective of this systematic review was to identify, systematically evaluate and summarize the available evidence on the efficacy and safety of hemodialysis strategies for pregnant CKD women. Sensitive search strategies were applied to six databases without data or language restrictions. Comparative (randomized and non-randomized) studies were prioritized. Two reviewers independently selected, extracted, and critically evaluated data from studies. The risk of bias assessment was performed using the ROBINS-I tool, considering the study design (non-randomized comparative observational studies). The certainty of the evidence was assessed using the GRADE approach. From 7210 references identified, six retrospective cohort studies were included (576 women). The effects of intensive hemodialysis (over 20 h/week) are uncertain for maternal and neonatal mortality (Peto odds ratio [OR] 0.85; 95% confidence interval [95% CI] 0.26-2.80), miscarriage (Peto OR 0, 38; 95% CI 0.12-1.23), stillbirths (Peto OR 0, 56; 95% CI 0.13-2.31), preterm birth (Peto OR 0.87; 95% CI 0.33-2.28), low birth weight (Peto OR 0.71; 95% CI 0.20-2.50) and congenital anomalies rates. The certainty of the evidence was very low due to studies methodological limitations and effect estimates imprecision. The uncertainty about intensive versus conventional hemodialysis effects for pregnant women with CKD and the imprecision in the estimated effects precludes any recommendation. The strategy choice must consider treatment availability, costs, and maternal social aspects until future studies provide more reliable evidence. PROSPERO CRD42021259237.

Plant-Based Diets Improve Maternal-Fetal Outcomes in CKD Pregnancies. Nutrients 2022; 14:nu14194203.

Abstract
Reducing protein intake in patients with chronic kidney disease (CKD) limits glomerular stress induced by hyperfiltration and can prevent the progression of kidney disease; data in pregnancy are limited. The aim of this study is to analyze the results obtained in CKD patients who followed a plant-based moderately protein-restricted diet during pregnancy in comparison with a propensity-score-matched cohort of CKD pregnancies on unrestricted diets. A total of 52 CKD pregnancies followed up with a protein-restricted plant-based diet (Torino, Italy) were matched with a propensity score based on kidney function and proteinuria with CKD pregnancies with unrestricted protein intake (Cagliari Italy). Outcomes included preterm (<37 weeks) and very preterm (<34 weeks) delivery and giving birth to a small-for-gestational-age baby. The median age in our cohort was 34 years, 63.46% of women were primiparous, and the median body mass index (BMI) was 23.15 kg/m2 with 13.46% of obese subjects. No statistical differences were found between women on a plant-based diet and women who were not in terms of age, parity, BMI, obesity, CKD stage, timing of referral, or cause of CKD. No differences were found between the two groups regarding the week of delivery. However, the combined negative outcome (birth before 37 completed gestational weeks or birth-weight centile <10) occurred less frequently in women following the diet than in women in the control group (61.54% versus 80.77%; p = 0.03). The lower risk was confirmed in a multivariable analysis adjusted for renal function and proteinuria (OR: 0.260 [Q1:0.093-Q3:0.724]; p = 0.010), in which the increase in proteinuria from the first to the last check-up before delivery was lower in patients on plant-based diets (median from 0.80 to 1.87 g/24 h; p: ns) than in controls (0.63 to 2.39 g/24 h p <0.0001). Plant-based, moderately protein-restricted diets in pregnancy in patients with CKD are associated with a lower risk of preterm delivery and small-for-gestational-age babies; the effect may be mediated by better stabilization of proteinuria.

Pregnancy after living kidney donation, a systematic review of the available evidence, and a review of the current guidance. Am J Transplant 2022; 22:2360-2380.

Abstract
Understanding and communicating the risk of pregnancy complications post-living kidney donation is imperative as the majority of living kidney donors (LKD) are women of childbearing age. We aimed to identify all original research articles examining complications in post-donation pregnancies and compared the quality and consistency of related guidelines. We searched Embase, MEDLINE, PubMed, society webpages, and guideline registries for English-language publications published up until December 18, 2020. Ninety-three articles were screened from which 16 studies were identified, with a total of 1399 post-donation pregnancies. The outcome of interest, post-donation pregnancy complications, was not calculable, and only a narrative synthesis of the evidence was possible. The absolute risk of pre-eclampsia increased from ~1%-3% pre-donation (lower than the general population) to ~4%-10% post-donation (comparable to the general population). The risks of adverse fetal and neonatal outcomes were no different between post-donation and pre-donation pregnancies. Guidelines and consensus statements were consistent in stating the need to inform LKDs of their post-donation pregnancy risk, however, the depth and scope of this guidance were variable. While the absolute risk of pregnancy complications remains low post-donation, a concerted effort is required to better identify and individualize risk in these women, such that consent to donation is truly informed.

Abstract
ObjectiveWe evaluated if there were more adverse gestational outcomes of pregnant women with unilateral congenital renal agenesis (UCRA). Study design: This single center retrospective case-control study compared maternal complications and neonatal outcomes from 25 women with UCRA to the outcomes of 125 women with two kidneys. Results: UCRA women had lower gestational weeks at birth and higher rates of preterm delivery (p = 0.004 and <0.001; respectively). Mothers had higher rates of preeclampsia and newborns with congenital anomalies and neonatal intensive care unit (NICU) admission (p = 0.009, 0.042, and 0.039; respectively). Unadjusted odds ratios were significantly higher for preterm delivery and for any APGAR score of <7 at the first 10 min and preeclampsia [OR (95% CI):13.5 (4.66-39.05), 31 (3.44-279.32) and 5.76 (1.33-24.84), respectively]. Conclusion: Maternal UCRA is a risk factor for less optimal obstetric and neonatal outcomes.

Abstract
Preeclampsia is a protean syndrome causing a kidney disease characterised by hypertension and proteinuria, usually considered transitory and reversible after delivery. Its prevalence ranges from 3-5 to 10% if all the related disorders are considered. This narrative review, on behalf of the Kidney and Pregnancy Study Group of the Italian Society of Nephrology, focuses on three reasons why preeclampsia should concern paediatric nephrologists and how they can play an important role in its prevention, as well as in the prevention of future kidney and cardiovascular diseases. Firstly, all diseases of the kidney and urinary tract diagnosed in paediatric age are associated with a higher risk of adverse pregnancy-related outcomes, including preeclampsia. Secondly, babies with low birth weights (small for gestational age, born preterm, or both) have an increased risk of developing the full panoply of metabolic diseases (obesity, hypertension, early-onset cardiopathy and chronic kidney disease) and girls are at higher risk of developing preeclampsia when pregnant. The risk may be particularly high in cases of maternal preeclampsia, highlighting a familial aggregation of this condition. Thirdly, pregnant teenagers have a higher risk of developing preeclampsia and the hypertensive disorders of pregnancy, and should be followed up as high risk pregnancies. In summary, preeclampsia has come to be seen as a window on the future health of both mother and baby. Identification of subjects at risk, early counselling and careful follow-up can contribute to reducing the high morbidity linked with this disorder.

Abstract
Chronic kidney disease (CKD) and end stage kidney disease are prevalent even in women of reproductive age. These are known to reduce fertility and successful pregnancy. There are chances of conception even in advanced CKD, though laden with complications. We present two cases of women who conceived in advanced CKD and were on haemodialysis in a tertiary hospital in Kenya, and review of literature.

Abstract
Recent trends in the diagnosis, treatment, and classification of collagen IV-associated kidney disease are likely to result in increasing numbers of people in adult nephrology practices who have a confirmed diagnosis of Alport syndrome. These trends include the increasing use of genetic testing in the diagnostic evaluation of people with hematuria, focal segmental glomerulosclerosis, and chronic kidney disease of unknown etiology; early treatment with inhibitors of the renin-angiotensin-aldosterone system to delay kidney failure; and application of an expanded definition of Alport syndrome based on genotype rather than phenotype. This commentary discusses these trends and their implications for the adult nephrologist.

Abstract
BACKGROUND Preeclampsia is a condition often superimposed to CKD. OBJECTIVE The purpose of this study was to evaluate the clinical characteristics and outcomes of pregnant women with chronic kidney disease (CKD) with suspected superimposed preeclampsia, stratified according to the degree of their angiogenic imbalance, as assessed by the soluble fms-like tyrosine kinase-1 (sFlt-1)/placental growth factor (PlGF) ratio. METHODS Using a cross-sectional design, we studied 171 pregnancies in patients with CKD and with suspected superimposed preeclampsia, admitted to a teaching hospital. Patients were divided into three groups based on their degree of angiogenic imbalance, evaluated by the sFlt-1/PlGF ratio: no angiogenic imbalance (sFlt-1/PlGF ratio≤ 38), mild angiogenic imbalance (sFlt-1/PlGF ratio> 38 to < 85), and severe angiogenic imbalance (sFlt-1/PlGF ratio≥ 85). Superimposed preeclampsia and preeclampsia-related adverse outcomes were defined according to The American College of Obstetricians and Gynecology criteria. Measurements of sFlt-1 and PlGF were performed on single serum samples using the Elecsys sFlt-1 and PlGF assays (Roche Diagnostics). Serum soluble endoglin (sEng) levels were also determined (ELISA R&D Systems, Minneapolis, MN). Glomerular filtration rate (GFR) was calculated using the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) formula, whenever possible on pre-prengancy data. RESULTS Patients with severe angiogenic imbalance had higher rates of confirmed superimposed preeclampsia and preeclampsia-related adverse maternal and perinatal outcomes (p < 0.001) when compared to patients with no or mild angiogenic imbalance. A significant trend towards higher serum sEng levels was observed as the degree of angiogenic imbalance increased. Interestingly, the rate of progression to superimposed preeclampsia increased progressively as the degree of angiogenic imbalance increased (no 11.8%, mild 60.0%, and severe 100%). CONCLUSION In women with CKD and suspected superimposed preeclampsia, severe angiogenic imbalance was associated with confirmed superimposed preeclampsia or progression to superimposed preeclampsia. Patients with no angiogenic imbalance displayed lower rates of progression to superimposed preeclampsia, whereas outcomes were intermediate, supporting a systematic use of sFlt-1/PlGF ratio, and other biomarkers in the clinical management of CKD pregnacies.

Abstract
Chronic kidney disease (CKD) is frequently accompanied by reproductive health challenges in females and males alike. Progression of CKD is associated with escalating impairment of the hypothalamic-pituitary-gonadal axis, which facilitates evolving ovarian, testicular, and sexual dysfunction. Common clinical reproductive health complications in CKD include abnormal menstruation, impaired sexual health, and reduced fertility. Though sex-specific factors, such as sex hormones and gonadal function, have a strong influence on reproductive health outcomes in CKD, a person's gender and gendered experience also have important implications. Institutionalized gender, gendered perceptions of health, and health care-seeking behaviors, as well as adherence to medical care, all have critical effects on reproductive health in CKD. This review endeavors to explore the implications of both sex and gender on overall reproductive health in individuals living with CKD.

Abstract
Introduction Women with advanced kidney disease are advised to wait until after transplant to pursue pregnancy, but the impact of pregnancy on estimated glomerular filtration rate (eGFR) decline and kidney histology is unclear. Methods We identified a cohort of women aged 18 to 44 years at transplant from 1996 to 2014 at our 3-site program (N = 816) and determined whether they had a pregnancy >20 weeks gestation post-transplant by chart review. Outcomes included rate of change in eGFR after pregnancy, changes in kidney histology before and after pregnancy, graft failure, and 50% reduction in eGFR. Results There were 37 women with one or more pregnancies lasting longer than 20 weeks gestation post-transplant. Comparing women with and without pregnancy post-transplant, there was a significant increase in the rate of eGFR decline after pregnancy (−2.4 ml/min per 1.73 m2 per year vs. −1.9 ml/min per 1.73 m2 per year in women with no pregnancy, P < 0.001). Pregnancy did not affect the risk of graft failure, death-censored graft failure, or 50% reduction in eGFR. Conclusion Pregnancy affects the rate of eGFR decline in the allograft. Postpregnancy biopsy findings revealed an increase in vascular injury, which could be a potential mechanism. We did not find a significant increase in risk of graft failure or reduction in eGFR by 50% owing to pregnancy.

Abstract
Severe maternal morbidity and mortality continue to increase in the United States, largely owing to chronic and newly diagnosed medical comorbidities. Interconception care, or care and management of medical conditions between pregnancies, can improve chronic disease control before, during, and after pregnancy. It is a crucial and time-sensitive intervention that can decrease maternal morbidity and mortality and improve overall health. Despite these potential benefits, interconception care has not been well implemented by the primary care community. Furthermore, there is a lack of guidelines for optimizing preconception chronic disease, risk stratifying postpartum chronic diseases, and recommending general collaborative management principles for reproductive-age patients in the period between pregnancies. As a result, many primary care providers, especially those without obstetric training, are unclear about their specific role in interconception care and may be unsure of effective methods for collaborating with obstetric care providers. In particular, internal medicine physicians, the largest group of primary care physicians, may lack sufficient clinical exposure to medical conditions in the obstetric population during their residency training and may feel uncomfortable in caring for these patients in their subsequent practice. The objective of this article is to review concepts around interconception care, focusing specifically on preconception care for patients with chronic medical conditions (eg, chronic hypertension, chronic diabetes mellitus, chronic kidney disease, venous thromboembolism, and obesity) and postpartum care for those with medically complicated pregnancies (eg, hypertensive disorders of pregnancy, gestational diabetes mellitus, excessive gestational weight gain, peripartum cardiomyopathy, and peripartum mood disorders). We also provide a pragmatic checklist for preconception and postpartum management.

Abstract
BACKGROUND The effect of urolithiasis on pregnancy-related outcomes remains unknown. The aim of this study was to determine the risk of adverse maternal and neonatal outcomes. METHODS We searched PubMed, Embase, and the Cochrane Library through December 2020 for studies reporting on adverse maternal and neonatal outcomes in patients with urolithiasis. Risk ratios (ORs) with 95% confidence intervals (CIs) were calculated for these outcomes in pregnant mothers with urolithiasis and compared to healthy controls. RESULTS Eight studies comprising 26,577 mothers with urolithiasis were included in our analysis. Preterm birth (OR = 1.63; 95% CI 1.37-1.95, p < 0.001) or very preterm birth risk (OR = 1.49, 95% CI 1.06-2.11, p = 0.02) was more common in patients with urolithiasis compared to healthy controls. Mothers with urolithiasis had an increased incidence of preeclampsia (OR = 1.75, 95% CI 1.33-2.3, p < 0.001), hypertension (OR = 2.97, 95% CI 1.31-6.71, p = 0.009), caesarean section (OR 1.31, 95% CI 1.11-1.55, p = 0.001), and gestational diabetes mellitus (OR 1.84, 95% CI 1.37-2.46, p < 0.001). CONCLUSION Patients with urolithiasis may be at increased risk of developing adverse maternal or neonatal outcomes.

Abstract
Alport syndrome is a multisystem disorder that universally affects the kidney and frequently involves the inner ear and the eye. Over the course of a lifetime, addressing the health care needs of a person with Alport syndrome and their family entails the services of primary providers, nephrologists, genetic counselors, audiologists, ophthalmologists, transplant physicians, kidney dieticians, and social workers as well as other healthcare professionals. This article attempts to provide context and guidance regarding the multidisciplinary care of Alport syndrome based on the natural history of the condition.

Abstract
BACKGROUND Prepregnancy kidney dysfunction has been associated with preterm birth, which is the leading cause of neonatal morbidity and mortality; however, the relation is not well understood. We determined the risk of preterm birth in women with prepregnancy kidney dysfunction, defined using pregnancy-specific serum creatinine cut points. METHODS This population-based cohort study in the province of Ontario, Canada, involved women aged 16 to 50 years who had a singleton birth between 2006 and 2016 and measurement of serum creatinine within 10 weeks preceding their estimated conception date. The exposure was abnormally elevated prepregnancy serum creatinine, defined as greater than the 95th percentile (> 77 μmol/L), a value derived from a population-based sample of women without known kidney disease who became pregnant soon after the measurement was obtained. The main outcome was any preterm birth from 23 to 36 weeks' gestation. Secondary outcomes included provider-initiated preterm birth before 37 weeks' gestation and spontaneous preterm birth before 37 weeks. RESULTS Among 55 946 pregnancies, preterm birth before 37 weeks' gestation occurred in 3956 women (7.1%). The risk of preterm birth before 37 weeks was higher among women with prepregnancy creatinine above the 95th percentile, relative to those with prepregnancy creatinine at or below the 95th percentile (9.1% v. 7.0%; adjusted relative risk [RR] 1.23, 95% confidence interval [CI] 1.09 to 1.38). The effect was significant for provider-initiated preterm birth (adjusted RR 1.30, 95% CI 1.11 to 1.52) but not for spontaneous preterm birth (adjusted RR 1.12, 95% CI 0.91 to 1.37). INTERPRETATION Given that prepregnancy kidney dysfunction conferred an increased risk of preterm birth, measurement of serum creatinine (a relatively inexpensive blood test) may form part of the assessment of risk for preterm birth among those planning pregnancy.

Abstract
Patients with chronic kidney disease are required to make difficult decisions, negotiating between the risks, burdens and benefits for any proposed course. This process can be extremely challenging, since these decisions involve inherent risks, which can impact on survival and quality of life. Shared decision-making offers a patient-centred approach in partnering with patients to make decisions about their treatment, which reflect their values and preferences. Shared decision-making can improve patient preparedness, motivation, satisfaction, and adherence to the treatment or decision agreed upon. In this review article, we outline the key principles of shared decision-making, and provide a framework with communication strategies to facilitate shared decision-making. We highlight the broad range and context of decisions faced by patients in several areas of nephrology care and discuss patient-important outcomes, priorities and motivations that underpin their decision-making. Preserving patient autonomy through shared decision-making ensures close consideration of patient preferences to enhance satisfaction with the decision reached and optimize outcomes important to patients.

Abstract
Background Immunoglobulin A nephropathy (IgAN) incidence peaks in childbearing age. Data on pregnancy outcomes in women with IgAN are limited. Methods We performed a register-based cohort study in a nationwide cohort of women with biopsy-verified IgAN in Sweden, comparing 327 pregnancies in 208 women with biopsy-verified IgAN and 1060 pregnancies in a matched reference population of 622 women without IgAN, with secondary comparisons with sisters to IgAN women. Adverse pregnancy outcomes, identified by way of the Swedish Medical Birth Register, were compared through multivariable logistic regression and presented as adjusted odds ratios (aORs). Main outcome was preterm birth (< 37 weeks). Secondary outcomes were preeclampsia, small for gestational age (SGA), low 5-min Apgar score (< 7), fetal or infant loss, cesarean section, and gestational diabetes. Results We found that IgAN was associated with an increased risk of preterm birth (13.1% vs 5.6%; aOR = 2.69; 95% confidence interval [CI] = 1.52–4.77), preeclampsia (13.8% vs 4.2%; aOR = 4.29; 95%CI = 2.42–7.62), SGA birth (16.0% vs 11.1%; aOR = 1.84; 95%CI = 1.17–2.88), and cesarean section (23.9% vs 16.2%; aOR = 1.74, 95%CI = 1.14–2.65). Absolute risks were low for intrauterine (0.6%) or neonatal (0%) death and for low 5-min Apgar score (1.5%), and did not differ from the reference population. Sibling comparisons suggested increased risks of preterm birth, preeclampsia, and SGA in IgAN, but not of cesarean section. Conclusion We conclude that although most women with IgAN will have a favorable pregnancy outcome, they are at higher risk of preterm birth, preeclampsia and SGA. Intensified supervision during pregnancy is warranted. Supplementary Information The online version contains supplementary material available at 10.1007/s40620-021-00979-2.

Abstract
Sexual and reproductive function are impacted negatively in individuals with chronic kidney disease and end-stage renal disease. Disruption of the hypothalamic-pituitary-gonadal axis plays a pivotal role in contributing to these manifestations as a result of decreasing kidney function and the development of uremia. Early menopause is encountered commonly in women with reduced kidney function, and treatment is problematic as a result of reduced kidney function changing the half-life of medications. Kidney transplantation corrects some of these abnormalities, but medications required after transplantation as well as the persistence of other comorbidities are barriers to normal restoration of gonadal dysfunction.

Abstract
Pregnancy rates in women on dialysis have increased in the last decades, thus making it a topic of growing interest. The rarity of this event is predominantly due to fertility problems and to the high rates of pregnancy failure including stillbirth, fetal, and neonatal deaths. We conducted a narrative review of existing literature in order to analyze the major issues about pregnancy on dialysis to give the reader a fully updated perspective about this topic which, even if not common, is becoming more and more frequent. Even if recently acquired knowledge has improved diagnosis and treatment of dialysis pregnancies focusing on several aspects, pregnancy on dialysis remains a great challenge for obstetricians and should be managed by a multidisciplinary expertise team. Dialysis in pregnancy may be necessary for women previously affected by end stage renal disease (ESRD) becoming pregnant, or in case of acute renal injury presenting for the first time during gestation or, again, in case of existent renal pathology worsening during pregnancy and requiring dialysis. Although some evidence suggests that more intensive dialysis regimens are correlated with better obstetric outcomes, the optimal therapeutic protocol still remains to be established.

Abstract
Objective: To evaluate the obstetric outcomes of pregnancies with chronic kidney disease (CKD) and to assess the prognostic factors on adverse obstetric outcomes. Methods: We retrospectively reviewed 101 singleton pregnancies with CKD. Obstetric outcomes were explored according to CKD stages. The composite adverse obstetric outcome was defined as at least one of stillbirth, neonatal death and delivery <34 weeks due to preeclampsia or fetal distress. Results: The incidences of preeclampsia, fetal growth restriction, perinatal mortality and composite adverse obstetric outcome were 40.5%, 26.7%, 14.8% and 37.6% respectively in pregnancies with CKD. Composite obstetric adverse outcome was significantly higher in pregnancies with CKD stage 4-5 than the other stages (p < 0.01). CKD stage 4-5 and baseline proteinuria >3 g/24 h were associated with composite obstetric adverse outcome (OR 43.2, p = 0.005 and OR 6.08, p = 0.01 respectively) comparing to stage 1 and proteinuria <0.5 g/24 h. Conclusion: Incidences of adverse obstetric outcomes are high even in early stages of CKD. CKD stage 4-5 and baseline proteinuria >3 g/24 h are poor prognostic factors.

Abstract
Unplanned pregnancies account for a large number of encountered pregnancies. One of the reasons for this is the lack of counseling surrounding contraception and subsequently lack of contraception use. A conversation during a regular CKD office visit of simply asking a woman what her plans are regarding pregnancy can lead to further discussion on timing of pregnancy and contraception and eventually safer outcomes for both the mother and fetus. Individual preference, as well as comorbid conditions, should be taken into account when deciding on optimal contraceptive methods. One must remember that contraception counseling and initiation of contraception should not be wrapped up in a single office visit, and there must be continued follow-up to ensure that the woman is using the contraceptive method correctly to prevent any future unplanned pregnancy.

Abstract
Women with chronic kidney disease (CKD) are at high risk for adverse outcomes in pregnancy. In the United States, pregnancy rates in women with risk factors for CKD such as obesity and advanced maternal age are increasing; thus, more pregnancies are likely to be affected by CKD. Strategies that involve coordinated multidisciplinary care to optimize preconception health, perform meticulous antenatal monitoring, and provide continued care in the postpartum "fourth trimester" appear to be most beneficial for both the mother and baby. Discussions surrounding preconception risk stratification should be individualized based on CKD stage/serum creatinine level, degree of hypertension and proteinuria, and comorbid conditions. Preparation for pregnancy should include optimization of comorbidities and medication adjustments to those compatible with pregnancy. Unless contraindicated, all women with CKD should be prescribed low-dose aspirin in pregnancy to reduce risk of preeclampsia. After delivery, women with CKD may benefit from an early postpartum visit (within 7-10 days) for blood pressure check and may require serial monitoring of serum creatinine and proteinuria as appropriate. Breastfeeding is safe and can be recommended for most women with CKD. A contraceptive plan that includes patients' preferences, feasibility, medical eligibility, duration, and effectiveness of the contraceptive method should be implemented.

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.

Clinical Predictors of Preeclampsia in Pregnant Women with Chronic Kidney Disease. ACTA ACUST UNITED AC 2020; 56:medicina56050213. [PMID: 32349458 PMCID: PMC7279325 DOI: 10.3390/medicina56050213] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/11/2020] [Revised: 04/22/2020] [Accepted: 04/24/2020] [Indexed: 12/05/2022]
Abstract
Background and Objectives: Pregnant women with chronic kidney disease (CKD) are at high risk of adverse maternal and fetal outcomes. Preeclampsia (PE) superimposed on CKD is estimated to occur in 21%–79% of pregnancies. Both conditions share common features such as proteinuria and hypertension, making differential diagnosis difficult. Objective: The aim of this study was to evaluate the incidence and the clinical-biological predictors of preeclampsia in pregnant women with CKD. Material and Methods: We retrospectively analyzed 34 pregnant women with pre-existing CKD admitted to our department between 2008 and 2017. Results: Among the 34 patients, 19 (55.8%) developed PE and the mean time of occurrence was 31.26 ± 2.68 weeks of gestation. The median value of 24-h proteinuria at referral was 0.87 g/day (interquartile range 0.42–1.50) and 47.1% of patients had proteinuria of ≥1 g/day. Patients with PE tended to be more hypertensive, with a more decreased renal function at referral and had significantly higher proteinuria (1.30 vs. 0.63 g/day, p = 0.02). Cox multivariate analysis revealed that proteinuria ≥1 g/day at referral and pre-existing hypertension were independently associated with PE (adjusted hazard ratio = 4.10, 95% confidence interval: 1.52–11.02, p = 0.005, adjusted hazard ratio = 2.62, 95% confidence interval: 1.01–6.77, p = 0.04, respectively). The cumulative risk of PE was significantly higher in pregnant women with proteinuria ≥1 g/day at referral (log-rank, p = 0.003). Proteinuria ≥ 1 g/day at referral and pre-exiting hypertension predicted PE development with accuracies of 73.5% and 64.7%, respectively. Conclusions: Pregnant patients with pre-existing CKD are at high risk of developing preeclampsia, while proteinuria ≥ 1 g/day at referral and pre-existing hypertension were independent predictors of superimposed preeclampsia.

Abstract
BACKGROUND Studies among pregnant Asian women with chronic kidney disease (CKD) have not been widely performed; therefore, clinical criteria for these patients have not been well established. METHODS We conducted a retrospective study among pregnant women with CKD who received prenatal care at our institution for 8 consecutive years. Primary outcome was the development of severe adverse events (SAEs). We analyzed correlations between primary outcome and CKD parameters [age, body mass index (BMI), estimated glomerular filtration rate (eGFR), urinary protein-creatinine ratio (UP), systolic blood pressure (SBP), diastolic blood pressure (DBP), and not normal blood pressure (non-NBP)] at the time of referral. Secondary outcomes were low birth weight (LBW), preterm delivery (PreD), and small for gestational age (SGA). We divided into two categories, CKD stage G1, and G2 or higher according to eGFR, and proteinuria negative and proteinuria positive according to UP, respectively. RESULTS We observed 89 pregnancies. SAE was observed in 28 pregnancies. In live birth cases, there were 28 PreD, 28 LBW and 13 SGA. Major SAEs included preeclampsia, superimposed preeclampsia, unscheduled cesarean section, neonatal intensive care unit admission, and fetal death. Stepwise logistic regression analysis selected eGFR (OR = 0.847, p = 0.026), SBP (OR = 1.897, p = 0.006) and proteinuria positive (OR = 2.96, p = 0.046) as the significant predictors of SAEs. There were no significant differences among the baseline characteristics stratified by SGA. CONCLUSIONS This is the first study to report pregnancy outcomes among Japanese non-disease-oriented patients with CKD. In Asians, especially in the Japanese population, kidney function, blood pressure and proteinuria might affect pregnancy outcomes.

Abstract
Background Serum anti-Müllerian hormone (AMH) is a biomarker of ovarian reserve. There are limited data to guide the clinical interpretation of AMH in women with chronic kidney disease (CKD). The purpose of this study was to examine AMH concentrations in women with CKD compared with women without CKD. Methods We conducted a prospective cohort study of serum AMH concentrations in 163 non-pregnant women with CKD. Serum AMH concentrations were compared with age-specific AMH centiles from 887 healthy female controls. Results Participants included 30 women with Stage 1 CKD, 37 women with Stage 2 CKD, 26 women with Stage 3a CKD, 31 women with Stage 3b CKD and 39 women with Stages 4 and 5 CKD. The median estimated glomerular filtration rate (eGFR) was 51 (interquartile range 31–80) mL/min/1.73 m2. Serum AMH concentrations were lower in all CKD stages compared with women without CKD. Women ages 20–24 years with CKD had comparable serum AMH concentrations (median 1.959 ng/mL) to women ages 35–39 years without CKD (median 1.995 ng/mL). There was no evidence that eGFR was an independent modifier of serum AMH concentrations. More than half of women with CKD (58%) were predicted to have a low response to gonadotrophin stimulation. Conclusions Women with CKD have a lower ovarian reserve and are predicted to have a lower ovarian response to gonadotrophin stimulation compared with women without CKD of a similar age. Women with CKD who fail to conceive within 6 months of regular unprotected intercourse should be considered for fertility assessment and intervention.

Abstract
Acute kidney injury (AKI) is a common and life-threatening complication in critically ill neonates. Gestational risk factors for AKI include premature birth, intrauterine growth restriction and low birthweight, which are associated with poor nephron development and are often the consequence of pre-gestational and gestational factors, such as poor nutritional status. Our understanding of how to best optimize renal development and prevent AKI is in its infancy; however, the identification of pre-gestational and gestational factors that increase the risk of adverse neonatal outcomes and the implementation of interventions, such as improving nutritional status early in pregnancy, have the potential to optimize fetal growth and reduce the risk of preterm birth, thereby improving kidney health. The overall risk of AKI among critically ill and premature neonates is exacerbated postnatally as these infants are often exposed to dehydration, septic shock and potentially nephrotoxic medications. Strategies to improve outcomes - for example, through careful evaluation of nephrotoxic drugs - may reduce the incidence of AKI and its consequences among this population. Management strategies and updated technology that will support neonates with AKI are greatly needed. Extremely premature infants and those who survive an episode of AKI should be screened for chronic kidney disease until early adulthood. Here, we provide an overview of our current understanding of neonatal AKI, focusing on its relationship to preterm birth and growth restriction. We describe factors that prevent optimal nephrogenesis during pregnancy and provide a framework for future explorations designed to maximize outcomes in this vulnerable population.

Abstract
BACKGROUND Although kidney transplant improves reproductive function in women with end-stage kidney disease (ESKD), pregnancy in kidney transplant recipients' remains challenging due to the risk of adverse maternal and fetal outcomes. METHODS We evaluated a retrospective cohort of 7,966 women who were aged 15-45 years and received a kidney transplant between January 1, 2005 and December 31, 2011 from the United States Renal Data System with Medicare as the primary payer for the entire three years after the date of transplantation. Unadjusted and adjusted rates of pregnancy in the first three post-transplant years were calculated, using Poisson regression for the adjustment. Factors associated with pregnancy, including race, were examined using logistic regression. RESULTS Overall, 293 pregnancies were identified in 7966 women. The unadjusted pregnancy rate was 13.8 per thousand person-years (PTPY) (95% confidence interval (CI), 12.3-15.5). Pregnancy rates were roughly constant in the years 2005-2011 except in 2005 and 2010. The rate of pregnancy was highest in Hispanic women (21.4 PTPY; 95% CI, 17.2-26.4) and Hispanic women had a higher likelihood of pregnancy as compared to white women (OR, 1.56; CI, 1.12-2.16). Pregnancy rates were lowest in women aged 30-34 years and 35-45 years at transplant, and women aged 30-34 years and 35-45 years at transplant were less likely to ever become pregnant during the follow-up (odds ratio [OR], 0.69; CI, 0.49-0.98 and OR, 0.14; CI 0.09-0.21 respectively) as compared to women aged 25-29 years at time of transplant. Women had higher rates of pregnancy in the second and third-year post-transplant (16.0 PTPY, CI 13.2-19.2 and 16.9 PTPY, CI 14.0-20.4) than in the first-year post-transplant (9.0 PTPY, CI 7.0-11.4). In transplant recipients, pregnancy was more likely in women with ESKD due to cystic disease (OR, 2.42; CI, 1.02-5.74) or glomerulonephritis (OR, 2.14; CI, 1.07-4.31) as compared to women with ESKD due to diabetes. CONCLUSION Hispanic race, younger age, and ESKD cause due to cystic disease or glomerulonephritis are significant factors associated with a higher likelihood of pregnancy. Pregnancy rates have been fairly constant over the last decade. This study improves our understanding of factors associated with pregnancy in kidney transplant recipients.
