Abstract
Despite significant improvements of renal and obstetrical management, pregnancies in women with glomerular diseases and with lupus nephritis continue to be associated with increased complications both for the mother and the fetus as compared to those of pregnancies in healthy women. To reduce the risk of these complications, planning pregnancy in a phase of stable remission of the underlining disease is necessary. A kidney biopsy is an important event in any phase of pregnancy. A kidney biopsy can be of help during counselling before pregnancy in cases of incomplete remission of the renal manifestations. In these situations, histological data may differentiate active lesions that require the reinforcement of therapy from chronic irreversible lesions that may increase the risk of complications. In pregnant women, a kidney biopsy can identify new-onset systemic lupus erythematous (SLE) and necrotizing or primitive glomerular diseases and distinguish them from other, more common complications. Increasing proteinuria, hypertension, and the deterioration of kidney function during pregnancy may be either due to a reactivation of the underlying disease or to pre-eclampsia. The results of the kidney biopsy suggest the need to initiate an appropriate treatment, allowing the progression of the pregnancy and the fetal viability or the anticipation of delivery. Data from the literature suggest avoiding a kidney biopsy beyond 28 weeks of gestation to minimize the risks associated with the procedure vs. the risk of preterm delivery. In case of the persistence of renal manifestations after delivery in women with a diagnosis of pre-eclampsia, a renal kidney assessment allows the final diagnosis and guides the therapy.

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.

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
Pregnancy requires several physiological adaptations from the maternal organism, including modifications in the glomerular filtration rate and renal excretion of several products. Chronic kidney disease (CKD) can negatively affect these modifications and consequently is associated with several adverse maternal and fetal adverse outcomes (gestational hypertension, progression of renal disease, pre-eclampsia, fetal growth restriction, and preterm delivery). A multidisciplinary vigilance of these pregnancies is essential in order to avoid and/or control the harmful effects associated with this pathology. Dialysis and transplantation can decrease the risks of maternal and fetal complications, nonetheless, the rates of complications remain high comparing with a normal pregnancy. Several recent developments in this area have improved quality and efficacy of treatment of pregnant women with CKD. This article summarizes the most recent literature about CKD and pregnancy.

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.

Clinical Predictors of Preeclampsia in Pregnant Women with Chronic Kidney Disease. ACTA ACUST UNITED AC 2020; 56:medicina56050213.

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 Maternal kidney disease (acute kidney injury (AKI), advanced chronic kidney disease (CKD), dependence on dialysis or a kidney transplant) has a substantial impact on pregnancy, with risks of significant perinatal morbidity. These pregnancies require integrated multidisciplinary care to manage a complex and often challenging clinical situation. The ability to deliver optimal care is currently hindered by a lack of understanding around prevalence, management and outcomes in Australia. This study aims to expand an evidence base to improve clinical care of women with serious kidney impairment in pregnancy. METHODS/DESIGN The "Kidney Disease in Pregnancy Study" is a national prospective cohort study of women with stage 3b-5 CKD (including dialysis and transplant) and severe AKI in pregnancy, using the Australasian Maternity Outcomes Surveillance System (AMOSS). AMOSS incorporates Australian maternity units with > 50 births/year (n = 260), capturing approximately 96% of Australian births. We will identify women meeting the inclusion criteria who give birth in Australia between 1st August 2017 and 31st July 2018. Case identification will occur via monthly review of all births in Australian AMOSS sites and prospective notification to AMOSS via renal or obstetric clinics. AMOSS data collectors will capture key clinical data via a web-based data collection tool. The data collected will focus on the prevalence, medical and obstetric clinical care, and maternal and fetal outcomes of these high-risk pregnancies. DISCUSSION This study will increase awareness of the issue of serious renal impairment in pregnancy through engagement of 260 maternity units and obstetric and renal healthcare providers across the country. The study results will provide an evidence base for pre-pregnancy counselling and development of models of optimal clinical care, clinical guideline and policy development in Australia. Understanding current practices, gaps in care and areas for intervention will improve the care of women with serious renal impairment, women with high-risk pregnancies, their babies and their families.

Abstract
Several studies have emphasized poor pregnancy outcomes associated with active lupus nephritis at the onset of conception. A few controversial studies have compared pregnancy outcome in patients with inactive lupus nephritis at conception and those without a history of lupus nephritis. This study aimed to find out if quiescent lupus nephritis at the onset of conception carries an increased risk of pregnancy complications compared to pregnancies without a history of lupus nephritis. This is a prospective cohort study carried out at the Rheumatology/Obstetrics Conjoint Clinic of Kasr Al-Ainy Hospital between January 2006 and December 2017. A total of 119 pregnancies were included: 72 pregnancies in group I (with a history of lupus nephritis) and 47 pregnancies in group II (non-renal systemic lupus erythematosus). They were subjected to full history taking, monthly clinical examination and laboratory investigations. In total, 16 (22.2%) renal pregnancies had renal flares at the onset of conception. Maternal complications, specifically renal flares, were reported in 36 (50%) pregnancies in group I and 13 (27.7) pregnancies in group II, with a significant difference ( p = 0.015). No significant differences were found concerning the frequency of pregnancy-related maternal and fetal complications between the two groups. When data were re-analyzed after excluding patients experiencing renal flares during the 6 months preceding pregnancy, there were no significant differences regarding the frequency of maternal and fetal complications between renal and non-renal pregnancies. In conclusion, lupus nephritis, per se, is not a risk factor for poor pregnancy outcome; rather, it is the lupus nephritis activity at the onset of pregnancy.

Abstract
Pregnancy is increasingly reported in chronic kidney disease (CKD), reflecting higher awareness, improvements in materno-foetal care, and a more flexible attitude towards “allowing” pregnancy in the advanced stages of CKD. Success is not devoid of problems and an important grey area regards the indications for starting dialysis (by urea level, clinical picture, and residual glomerular filtration rate) and for dietary management. The present case may highlight the role of plant-based diets in dietary management in pregnant CKD women, aimed at retarding dialysis needs. The case. A 28-year-old woman, affected by glomerulocystic disease and unilateral renal agenesis, in stage-4 CKD, was referred at the 6th week of amenorrhea: she weighed 40 kg (BMI 16.3), was normotensive, had no sign of oedema, her serum creatinine was 2.73 mg/dL, blood urea nitrogen (BUN) 35 mg/dL, and proteinuria 200 mg/24 h. She had been on a moderately protein-restricted diet (about 0.8 g/kg/real body weight, 0.6 per ideal body weight) since childhood. Low-dose acetylsalicylate was added, and a first attempt to switch to a protein-restricted supplemented plant-based diet was made and soon stopped, as she did not tolerate ketoacid and aminoacid supplementation. At 22 weeks of pregnancy, creatinine was increased (3.17 mg/dL, BUN 42 mg/dL), dietary management was re-discussed and a plant-based non-supplemented diet was started. The diet was associated with a rapid decrease in serum urea and creatinine; this favourable effect was maintained up to the 33rd gestational week when a new rise in urea and creatinine was observed, together with signs of cholestasis. After induction, at 33 weeks + 6 days, she delivered a healthy female baby, adequate for gestational age (39th centile). Urea levels decreased after delivery, but increased again when the mother resumed her usual mixed-protein diet. At the child’s most recent follow-up visit (age 4 months), development was normal, with normal weight and height (50th–75th centile). In summary, the present case confirms that a moderate protein-restricted diet can be prescribed in pregnancies in advanced CKD without negatively influencing foetal growth, supporting the importance of choosing a plant-based protein source, and suggests focusing on the diet’s effects on microcirculation to explain these favourable results.

Abstract
In both women and men, chronic kidney disease (CKD) is associated with decreased fertility. Though a multitude of factors contribute to the reduction in fertility in this population, progressively impaired function of the hypothalamic-pituitary-gonadal axis appears to play a key role in the pathophysiology. There is limited research on strategies to manage infertility in the CKD population, but intensive hemodialysis, kidney transplantation, medication management and assisted reproductive technologies (ART) have all been proposed. Though fertility and reproductive care are reported as important elements of care by CKD patients themselves, few nephrology clinicians routinely address fertility and reproductive care in clinical interactions. Globally, the average age of parenthood is increasing, with concurrent growth and expansion in the use of ART. Coupled with an increasing prevalence of CKD in women and men of reproductive age, the importance of understanding fertility and reproductive technologies in this population is highlighted. This review endeavors to explore the female and male factors that affect fertility in the CKD population, as well as the evidence supporting strategies for reproductive care.

A Systematic Review on Materno-Foetal Outcomes in Pregnant Women with IgA Nephropathy: A Case of "Late-Maternal" Preeclampsia? J Clin Med 2018; 7:jcm7080212. [PMID: 30103519 PMCID: PMC6111833 DOI: 10.3390/jcm7080212] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/01/2018] [Revised: 08/09/2018] [Accepted: 08/10/2018] [Indexed: 02/07/2023] Open
Abstract
Background: IgA nephropathy is the most common primary glomerulonephritis in pregnancy and shares with other immunologic diseases and kidney diseases a relationship with adverse maternal outcomes, whose entity and pattern is only partially quantified. Recent studies provide new information and a systematic review regarded progression of kidney disease. The discussion of the outcomes with respect to low-risk pregnancies may help to perfect the estimation of the risks, and to identify specific research needs. Methods: A search strategy was built on Medline, EMBASE and the Cochrane review for the period January 2000–April 2017, aimed at retrieving both case series (defined as with at least 6 pregnancies in women with IgA nephropathy) and case reports, to look into rare occurrences. All papers, with or without control groups, were selected if they reported on at least one pregnancy outcome, or on long-term kidney function. Search strategy, paper selection and data extraction were done in duplicate (PROSPERO N 42016042623). Meta-analysis of case series was performed with Metanalyst Beta 3.13. Case reports were analysed narratively. Results: The search retrieved 556 papers, of which 27 were included (13 series and 14 case-reports). The case series report on 581 women with 729 pregnancies. The analysis was performed in comparison to the available control groups: 562 non-pregnant controls were available for the analysis of progression of kidney disease. As for pregnancy related outcomes (preeclampsia (PE), pregnancy induced hypertension (PIH), preterm birth, small babies), we meta-analyzed the data with respect to the only series of low-risk pregnancies (1418 pregnancies). When compared with women who never got pregnant after diagnosis of IgA nephropathy, in the present meta-analysis pregnancy in women with IgA nephropathy was not associated with a higher risk of progression of kidney disease, possibly due to the overall preserved kidney function at baseline: end-stage kidney disease (OR 0.68; CI 0.28–1.65). Conversely, the incidence of adverse pregnancy-related outcomes was increased compared to low-risk controls: PE and PIH were more than ten-fold increased (OR 11.80; CI 7.53–18.48 and OR 10.39; CI 5.45–19.80), while the increase in risk of preterm birth and “low birth weight babies” was less marked (OR 3.37; CI 1.91–5.95 and OR 2.36; CI 1.52–3.66), a discrepancy suggesting the occurrence of “late” or “maternal” PE, that may affect less severely foetal growth or shorten gestation. In conclusion, in the present meta-analysis IgA nephropathy was not associated with an increased progression of kidney disease. The more than ten-fold increased risk of PIH and PE, in combination with a doubled risk of small babies, suggests the occurrence of “late” or “maternal” PE, usually less affecting early foetal growth. This finding may be of help in defining control policies, while further research is needed to guide clinical management.

Abstract
Kidney transplantation (KT) is often considered to be the method best able to restore fertility in a woman with chronic kidney disease (CKD). However, pregnancies in KT are not devoid of risks (in particular prematurity, small for gestational age babies, and the hypertensive disorders of pregnancy). An ideal profile of the potential KT mother includes “normal” or “good” kidney function (usually defined as glomerular filtration rate, GFR ≥ 60 ml/min), scant or no proteinuria (usually defined as below 500 mg/dl), normal or well controlled blood pressure (one drug only and no sign of end-organ damage), no recent acute rejection, good compliance and low-dose immunosuppression, without the use of potentially teratogen drugs (mycophenolic acid and m-Tor inhibitors) and an interval of at least 1–2 years after transplantation. In this setting, there is little if any risk of worsening of the kidney function. Less is known about how to manage “non-ideal” situations, such as a pregnancy a short time after KT, or one in the context of hypertension or a failing kidney. The aim of this position statement by the Kidney and Pregnancy Group of the Italian Society of Nephrology is to review the literature and discuss what is known about the clinical management of CKD after KT, with particular attention to women who start a pregnancy in non-ideal conditions. While the experience in such cases is limited, the risks of worsening the renal function are probably higher in cases with markedly reduced kidney function, and in the presence of proteinuria. Well-controlled hypertension alone seems less relevant for outcomes, even if its effect is probably multiplicative if combined with low GFR and proteinuria. As in other settings of kidney disease, superimposed preeclampsia (PE) is differently defined and this impairs calculating its real incidence. No specific difference between non-teratogen immunosuppressive drugs has been shown, but calcineurin inhibitors have been associated with foetal growth restriction and low birth weight. The clinical choices in cases at high risk for malformations or kidney function impairment (pregnancies under mycophenolic acid or with severe kidney-function impairment) require merging clinical and ethical approaches in which, beside the mother and child dyad, the grafted kidney is a crucial “third element”.

Abstract
BACKGROUND Analysis the maternal and fetal risk predictors in pregnancy in conjunction with chronic glomerulonephritis (CGN) patients are helpful to understand the influence of kidney diseases on pregnancy and the effects of pregnancy on kidney diseases. The aim of this study was to determine the predictors of adverse maternal and fetal outcomes in CGN patients. MATERIAL AND METHODS Maternal and fetal outcomes in 64 pregnancies of CGN patients were retrospectively analyzed. We randomly selected 100 low-risk-pregnancy women without chronic kidney disease (CKD) at the same time as the control group. Clinical manifestations, laboratory data, medication, and outcomes during pregnancies of these patients were analyzed by univariate and logistic regression. RESULTS CGN patients were associated with higher adverse pregnancy outcomes versus general pregnancies. The gestational ages are shorter, and the incidence of preeclampsia, gestational hypertension, and abortion were increased. The rates of premature delivery, low birth weights, and intrauterine growth restriction were higher in the CGN group. Prenatal proteinuria and blood pressure were significantly increased compared with pre-pregnancy stage. Proteinuria (0.9±0.6 g/d vs. 0.5±0.3 g/d, P=0.032) and hypertension (6.9% vs. 3.4%, P=0.021) at 6 months after delivery were aggravated. Prenatal proteinuria ≥3.5 g/d (OR 12.22, 95%CI 3.16~47.32, P=0.001) was the maternal risk predictor in pregnancy. Prenatal blood pressure ≥160/110 mmHg (OR 8.97, 95%CI 1.69~47.53, P=0.010) and uric acid ≥363 μmol/L (OR 7.35, 95%CI 1.88~28.76, P=0.004) were the fetal risk predictors in pregnancy in conjunction with CGN patients. CONCLUSIONS Maternal-fetal risks are increased in pregnancies in conjunction with CGN patients. Prenatal proteinuria ≥3.5 g/d, BP ≥160/110 mmHg, and uric acid ≥363 μmol/L were the maternal and fetal risk predictors in pregnancy.

Abstract
Introducción. La enfermedad renal poliquística (PKD, por su sigla en inglés) es una enfermedad genética frecuente en la que se desarrollan de forma progresiva lesiones quísticas que reemplazan el parénquima renal. Es una causa de insuficiencia renal terminal y una indicación común para diálisis y trasplante renal. Existen dos presentaciones de esta enfermedad que se distinguen por sus patrones de herencia: la enfermedad renal poliquística dominante (ADPKD, por su sigla en inglés) y la enfermedad renal poliquística recesiva (ARPKD, por su sigla en inglés).Objetivo. Resumir los aspectos más relevantes de la enfermedad renal: epidemiología, fisiopatología, diagnóstico, manifestaciones clínicas, tratamiento y pronóstico.Materiales y métodos. Revisión sistemática de la literatura en las bases de datos PubMed, Lilacs, UptoDate y Medline con los siguientes términos: enfermedades renales poliquísticas, riñón poliquístico autosómico dominante y riñón poliquístico autosómico recesivo.Resultados. Se encontraron 271 artículos y se escogieron 64 con base en su importancia.Conclusiones. Todo paciente con enfermedad renal poliquística en insuficiencia renal grado V debe ser estudiado para un trasplante renal; en la gran mayoría de los casos no se encontrará contraindicación para realizarlo.

Abstract
With the increasing prevalence of chronic kidney disease (CKD) worldwide, the number of pregnant women with various degrees of renal dysfunction is expected to increase. There is a bidirectional relation between CKD and pregnancy in which renal dysfunction negatively affects pregnancy outcomes, and the pregnancy can have a deleterious impact on various aspects of kidney disease. It has been shown that even mild renal dysfunction can increase considerably the risk of adverse maternal and fetal outcomes. Moreover, data suggest that a history of recovery from acute kidney injury is associated with adverse pregnancy outcomes. In addition to kidney dysfunction, maternal hypertension and proteinuria predispose women to negative outcomes and are important factors to consider in preconception counseling and the process of risk stratification. In this review, we provide an overview of the physiologic renal changes during pregnancy as well as available data regarding CKD and pregnancy outcomes. We also highlight the important management strategies in women with certain selected renal conditions that are seen commonly during the childbearing years. We call for future research on underexplored areas such as the concept of renal functional reserve to develop a potential clinical tool for prognostication and risk stratification of women at higher risk for complications during pregnancy.

Abstract
No data are available about the impact of pregnancy on the long-term outcome of lupus nephritis. Thirty-two women with lupus nephritis with a 10-year follow-up after their first pregnancy ("women who gave birth") and 64 matched controls with the same follow-up and who never had pregnancies ("controls") were compared for the occurrence of SLE flares, chronic kidney disease (CKD), and SLICC/ACR Damage Index (SDI) in the post pregnancy period. The same evaluations were done before and after pregnancy in women who gave birth. The predictors of CKD and damage accrual in the whole population were studied. All patients were Caucasians and had biopsy proven LN. At conception and after 10 years, in both groups, less than 10% of patients had active renal disease (p = ns). Controls had more frequent arterial hypertension (p = 0.025). Between the two groups there was no difference in SLE flares and in CKD free survival curves (p = 0.6 and p = 0.37) during the 10-year follow-up. In both groups, the temporal trend, based on annual evaluation, of glomerular filtration rate and serum creatinine shows a significant decrease and increase respectively. However, the women who gave birth persistently maintained better values of renal function than controls during the whole follow-up (P = 0.00001). There was no difference in the CKD-free survival curves. SDI did not increase significantly in women who gave birth in comparison to controls. All the above mentioned clinical parameters were comparable before and after pregnancy in the women who gave birth. Among the basal clinical characteristics, high serum creatinine and occurrence of SLE flares predicted CKD, whereas low levels of C3, pre-existing damage score, and occurrence of SLE flares predicted SDI increase. Pregnancy was not a predictor of CKD or SDI increase. Carrying a pregnancy during inactive lupus nephritis does not seem to increase the rate of SLE flares, worsen renal prognosis or increase SDI significantly in the very long-term.

Abstract
BACKGROUND Breastfeeding is a widely encouraged practice due to its benefits for mother and the infant. Little is known about the impact of disease states, such as kidney dysfunction and childbirth complications, on the composition of breast milk. METHODS We describe a case of a 35-year-old woman who suffered a postpartum hemorrhage, was administered a contrast dye prior to computer tomography, and developed an acute kidney injury. Using nuclear magnetic resonance spectrometry, we measured composition of milk in acute kidney injury. The amount of dye secreted into milk was determined using a spectroscopic assay. RESULTS Here we show that acute kidney injury results in changes in milk composition, but it does not significantly affect major macronutrients. We also determine that iodinated computer tomography contrast dye does not accumulate in milk in appreciable amounts. CONCLUSION Acute kidney injury has impact on breast milk. Intravenous administration of computer tomography contrast dye does not result in significantly elevated levels in milk.

Abstract
Preeclampsia (PE) is a protean syndrome causing a transitory kidney disease, characterised by hypertension and proteinuria, ultimately reversible after delivery. Its prevalence is variously estimated, from 3 to 5% to 10% if all the related disorders, including also pregnancy-induced hypertension (PIH) and HELLP syndrome (haemolysis, increase in liver enzyme, low platelets) are included. Both nephrologists and obstetricians are involved in the management of the disease, according to different protocols, and the clinical management, as well as the role for each specialty, differs worldwide. The increased awareness of the role of chronic kidney disease in pregnancy, complicating up to 3% of pregnancies, and the knowledge that PE is associated with an increased risk for development of CKD later in life have recently increased the interest and redesigned the role of the nephrologists in this context. However, while the heterogeneous definitions of PE, its recent reclassification, an emerging role for biochemical biomarkers, the growing body of epidemiological data and the new potential therapeutic interventions lead to counsel long-term follow-up, the lack of resources for chronic patients and the increasing costs of care limit the potential for preventive actions, and suggest tailoring specific interventional strategies. The aim of the present position statement of the Kidney and Pregnancy Study Group of the Italian Society of Nephrology is to review the literature and to try to identify theoretical and pragmatic bases for an agreed management of PE in the nephrological setting, with particular attention to the prevention of the syndrome (recurrent PE, presence of baseline CKD) and to the organization of the postpartum follow-up.

Abstract
Chronic kidney disease (CKD) is increasingly encountered in pregnancy, and hypertension is frequently concomitant. In pregnancy, the prevalence of CKD is estimated to be about 3%, while the prevalence of chronic hypertension is about 5-8%. The prevalence of hypertension and CKD in pregnancy is unknown. Both are independently related to adverse pregnancy outcomes, and the clinical picture merges with pregnancy-induced hypertension and preeclampsia. Precise risk quantification is not available, but risks linked to CKD stage, hypertension, and proteinuria are probably multiplicative, each at least doubling the rates of preterm and early preterm delivery, small for gestational age babies, and related outcomes. Differential diagnosis (based upon utero-placental flows, fetal growth, and supported by serum biomarkers) is important for clinical management. In the absence of guidelines for hypertension in CKD pregnancies, the ideal blood pressure goal has not been established; we support a tailored approach, depending on compliance, baseline control, and CKD stages, with strict blood pressure monitoring. The choice of antihypertensive drugs and the use of diuretics and of erythropoiesis-stimulating agents (ESAs) are still open questions which only future studies may clarify.

Abstract
BACKGROUND Pregnancy in women with advanced CKD becoming increasingly common. However, experience with low-protein diets in CKD patients in pregnancy is still limited. Aim of this study is to review the results obtained over the last 15 years with moderately restricted low-protein diets in pregnant CKD women (combining: CKD stages 3-5, proteinuria: nephrotic at any time, or > =1 g/24 at start or referral; nephrotic in previous pregnancy). CKD patients on unrestricted diets were employed for comparison. METHODS STUDY PERIOD January, 2000 to September, 2015: 36 on-diet pregnancies (31 singleton deliveries, 3 twin deliveries, 1 pregnancy termination, 1 miscarriage); 47 controls (42 singleton deliveries, 5 miscarriages). The diet is basically vegan; since occasional milk and yoghurt are allowed, we defined it vegan-vegetarian; protein intake (0.6-0.8 g/Kg/day), keto-acid supplementation, protein-unrestricted meals (1-3/week) are prescribed according to CKD stage and nutritional status. Statistical analysis was performed as implemented on SPSS. RESULTS Patients and controls were similar (p: ns) at baseline with regard to age (33 vs 33.5), referral week (7 vs 9), kidney function (CKD 3-5: 48.4 % vs 64.3 %); prevalence of hypertension (51.6 % vs 40.5 %) and proteinuria >3 g/24 h (16.1 % vs 12.2 %). There were more diabetic nephropathies in on-diet patients (on diet: 31.0 % vs controls 5.3 %; p 0.007 (Fisher)) while lupus nephropathies were non-significantly higher in controls (on diet: 10.3 % vs controls 23.7 %; p 0.28 (Fisher)). The incidence of preterm delivery was similar (<37 weeks: on-diet singletons 77.4 %; controls: 71.4 %). The incidence of other adverse pregnancy related outcomes was non-significantly lower in on-diet patients (early preterm delivery: on diet: 32.3 % vs controls 35.7 %; birth-weight = <1.500 g: on diet: 9.7 % vs controls 23.8 %). None of the singletons in the on-diet series died, while two perinatal deaths occurred among the controls (p = 0.505). The incidence of small for gestational age (SGA <10th centile) and/or extremely preterm babies (<28th week) was significantly lower in singletons from on-diet mothers than in controls (on diet: 12.9 % vs controls: 33.3 %; p: 0.04 (Fisher)). CONCLUSION Moderate protein restriction in the context of a vegan-vegetarian supplemented diet is confirmed as a safe option in the management of pregnant CKD patients.

Abstract
Parenthood is a central focus for women with chronic kidney disease, but raises important fears and uncertainties about risks to their own and their baby’s health. Pregnancy in women with background kidney disease, women receiving dialysis, or those with a functioning kidney transplant poses a challenging clinical scenario, associated with high maternal–fetal morbidity and potential impact on maternal renal health. Improvements in care over recent decades have led to a paradigm shift with cautious optimism and growing interest regarding pregnancies in women with chronic kidney disease. In this review, we discuss obstetric and renal outcomes, and practical aspects of management of pregnancy in this complex cohort.

A best practice position statement on pregnancy in chronic kidney disease: the Italian Study Group on Kidney and Pregnancy. J Nephrol 2016; 29:277-303. [PMID: 26988973 PMCID: PMC5487839 DOI: 10.1007/s40620-016-0285-6] [Citation(s) in RCA: 75] [Impact Index Per Article: 9.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/17/2015] [Accepted: 02/08/2016] [Indexed: 01/09/2023]
Abstract
Pregnancy is increasingly undertaken in patients with chronic kidney disease (CKD) and, conversely, CKD is increasingly diagnosed in pregnancy: up to 3 % of pregnancies are estimated to be complicated by CKD. The heterogeneity of CKD (accounting for stage, hypertension and proteinuria) and the rarity of several kidney diseases make risk assessment difficult and therapeutic strategies are often based upon scattered experiences and small series. In this setting, the aim of this position statement of the Kidney and Pregnancy Study Group of the Italian Society of Nephrology is to review the literature, and discuss the experience in the clinical management of CKD in pregnancy. CKD is associated with an increased risk for adverse pregnancy-related outcomes since its early stage, also in the absence of hypertension and proteinuria, thus supporting the need for a multidisciplinary follow-up in all CKD patients. CKD stage, hypertension and proteinuria are interrelated, but they are also independent risk factors for adverse pregnancy-related outcomes. Among the different kidney diseases, patients with glomerulonephritis and immunologic diseases are at higher risk of developing or increasing proteinuria and hypertension, a picture often difficult to differentiate from preeclampsia. The risk is higher in active immunologic diseases, and in those cases that are detected or flare up during pregnancy. Referral to tertiary care centres for multidisciplinary follow-up and tailored approaches are warranted. The risk of maternal death is, almost exclusively, reported in systemic lupus erythematosus and vasculitis, which share with diabetic nephropathy an increased risk for perinatal death of the babies. Conversely, patients with kidney malformation, autosomal-dominant polycystic kidney disease, stone disease, and previous upper urinary tract infections are at higher risk for urinary tract infections, in turn associated with prematurity. No risk for malformations other than those related to familiar urinary tract malformations is reported in CKD patients, with the possible exception of diabetic nephropathy. Risks of worsening of the renal function are differently reported, but are higher in advanced CKD. Strict follow-up is needed, also to identify the best balance between maternal and foetal risks. The need for further multicentre studies is underlined.
