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
BACKGROUND The outcomes of pregnancy in women with renal diseases remain controversial. The purpose of the study was to report fetal and maternal outcomes among women with glomerular disease in comparison with healthy pregnant women and a review of the current literature on this issue. METHODS Retrospective analysis included 72 pregnancies in 62 women with biopsy-proven glomerulonephritis (GN) (in 65.3% of cases, immunoglobulin A nephropathy was found). The control group consisted of 315 healthy pregnant women. We assessed fetal (prematurity, low birth weight, hypotrophy, fetal malformation, or intrauterine death) and maternal (gestational hypertension, preeclampsia, deterioration in kidney function, and maternal death) outcomes. Descriptive data analysis, Fisher's exact test, unpaired Student's t test, and ANOVA were performed. RESULTS Hypertension prevalence among the GN group and controls was 76.4 and 10.2%, respectively. Preeclampsia complicated 29.2% of pregnancies among women with GN and 2.9% of controls. In 8.3% of patients, at least a 50% decrease in GFR during pregnancy was observed. Preterm delivery prevalence in the GN group and controls was 74.7 and 12.7%, respectively. Hypotrophy was diagnosed in 12.5% of cases from the GN group and 5.4% of controls. The analysis showed that low estimated glomerular filtration rate, hypertension, and proteinuria were risk factors of adverse neonatal outcomes. CONCLUSION Women with GN are a risk factor of adverse pregnancy outcomes. As pregnancy complications are more prevalent across all the CKD stages, even in patients with near-normal kidney function, they require specialized care. It might be advisable to screen pregnant women for the presence of CKD, as especially in the early stage, it is often asymptomatic. Both hypertension and proteinuria are risk factors for neonatal and maternal complications.

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.

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
RATIONALE IgA nephropathy is one of the most common causes of renal hypertension. The clinical management of IgA renal patients during pregnancy is challenging, as complex pathophysiological changes may occur that affect both the patient's prognosis and the outcome of the pregnancy. PATIENT CONCERNS A 36-year-old woman with a family history of hypertension and at least one year of untreated mild high blood pressure was admitted to our hospital in the 28th week of pregnancy. She suffered from hypertensive disorder complicating pregnancy (HDCP) with renal insufficiency and stillbirth. Treatment with duplex antihypertensive drugs did not improve her blood pressure and she presented with abnormal renal function. DIAGNOSES A renal biopsy led to the diagnosis of a grade IV IgA nephropathy (Lee's grading system) with renal hypertension. INTERVENTIONS The prescribed treatment regimen consisted of low dose cyclophosphamide 0.2 g per day for two days, followed by daily oral administration of 30 mg prednisone, 30 mg Nifedipine extended-release tablets and 80 mg Telmisartan to regulate the blood pressure. OUTCOMES The medication with a combination of antihypertensive and immunosuppressive drugs led to a clinical improvement with a nearly normal renal function and a stable blood pressure during the one-year follow-up. LESSONS This case underlines that 1) the pregnancy outcomes of patients with IgA nephropathy are variable and depend on the renal function, blood pressure, status of urine proteins and the renal histological grade, and 2) especially female patients of childbearing age with hypertension need to be carefully examined to determine the cause of hypertension to avoid damage to target organs and complications during pregnancy.

Abstract
During pregnancy, CKD increases both maternal and fetal risk. Adverse maternal outcomes include progression of underlying renal dysfunction, worsening of urine protein, and hypertension, whereas adverse fetal outcomes include fetal loss, intrauterine growth restriction, and preterm delivery. As such, pregnancy in young women with CKD is anxiety provoking for both the patient and the clinician providing care, and because the heterogeneous group of glomerular diseases often affects young women, this is an area of heightened concern. In this invited review, we discuss pregnancy outcomes in young women with glomerular diseases. We have performed a systematic review in attempt to better understand these outcomes among young women with primary GN, we review the studies of pregnancy outcomes in lupus nephritis, and finally, we provide a potential construct for management. Although it is safe to say that the vast majority of young women with glomerular disease will have a live birth, the counseling that we can provide with respect to individualized risk remains imprecise in primary GN because the existing literature is extremely dated, and all management principles are extrapolated primarily from studies in lupus nephritis and diabetes. As such, the study of pregnancy outcomes and management strategies in these rare diseases requires a renewed interest and a dedicated collaborative effort.

Abstract
OBJECTIVE This study is designed to evaluate which factors would relate to deterioration of renal function (DRF) after delivery in pregnant women with chronic kidney disease (CKD). MATERIALS AND METHODS This study included 156 singleton pregnancies of 139 women with CKD at our institution from 2001 to 2010. DRF was defined as the shift of CKD stage into another more severe stage. The relevant variables were compared between women who had DRF (n = 39) and the controls (n = 117). RESULTS The number of transplantation or dialysis cases after delivery was 5.8%. DRF occurred in 25% of the study patients. From a logistic regression model, the factors that influence DRF were the presence of glomerulonephritis [odds ratio (OR) 3.56, 95% confidence interval (CI) 1.18-10.81], significant proteinuria prior to pregnancy (≥3 g/d or 3+ more dipstick; OR 3.43, 95% CI 1.14-10.33), and treatment with antiplatelet agents (OR 0.30, 95% CI 0.09-0.94). Receiver-operating characteristic curve analysis confirmed that the estimated glomerular filtration rate (eGFR) of 75 mL/min/1.73 m(2) or more before conception is not a risk factor for DRF after delivery (negative predictive value 0.788). CONCLUSION This was the first report to reveal a clear cutoff value regarding DRF in pregnant woman with CKD. There is an almost 78% risk of developing DRF after delivery in patients showing eGFR of 75 mL/min/1.73 m(2) or more before conception.

Abstract
BACKGROUND The outcomes of pregnancy in immunoglobulin A nephropathy (IgAN) are controversial. This cohort study assessed the effects of pregnancy on kidney disease progression and risk factors for adverse pregnancy outcomes in patients with IgAN. STUDY DESIGN A cohort study. SETTING & PARTICIPANTS Women of child-bearing age with IgAN and minimum follow-up of 1 year after biopsy from December 2003 to September 2014. PREDICTORS Pregnancy, treated as a time-dependent variable; baseline (at time of biopsy) estimated glomerular filtration rate (eGFR), proteinuria, blood pressure, and kidney pathology (Oxford MEST classification). OUTCOMES Kidney disease progression event, defined as 30% decline in eGFR or end-stage kidney disease; rate of eGFR decline; and adverse pregnancy outcomes, including severe preeclampsia and fetal loss. RESULTS Of 413 patients enrolled, 266 (64.4%), 101 (24.5%), 40 (9.6%), and 6 (1.5%) had chronic kidney disease (CKD) stages 1, 2, 3, and 4, respectively. During follow-up, 104 had 116 pregnancies, of which 110 continued beyond week 20; 309 patients did not become pregnant. After adjustment for age, eGFR, mean arterial pressure, proteinuria, and pathology class at the time of biopsy, subsequent pregnancy among patients with CKD stages 3 to 4, but not CKD stages 1 to 2, was associated with faster eGFR decline (-7.44 vs -3.90mL/min/1.73m2 per year; P=0.007) and increased incidence of kidney progression events (HR, 5.14; 95% CI, 1.16-22.74) compared with patients who did not become pregnant. LIMITATIONS Relatively small sample size and single-center experience. CONCLUSIONS Pregnancy accelerated kidney disease progression in women with IgAN and CKD stage 3, but not in those at stage 1 or 2.

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.

Abstract
BACKGROUND AND OBJECTIVES We undertook a systematic review and meta-analysis of published cohort studies and case-control studies to estimate (1) the risk of pregnancy complications among patients with CKD versus those without CKD and (2) the risk of CKD progression among pregnant patients versus nonpregnant controls with CKD. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS We searched electronic databases for studies published between 1946 and 2014, and we reviewed articles using validity criteria. Random-effects analytical methods were used. RESULTS Twenty-three studies (14 with data for adverse pregnancy outcomes and 9 for renal outcomes) with 506,340 pregnancies were included. Pregnancy with CKD had greater odds of preeclampsia (odds ratio [OR], 10.36; 95% confidence interval [95% CI], 6.28 to 17.09), premature delivery (OR, 5.72; 95% CI, 3.26 to 10.03), small for gestational age/low birth weight (OR, 4.85; 95% CI, 3.03 to 7.76), cesarean section (OR, 2.67; 95% CI, 2.01 to 3.54), and failure of pregnancy (OR, 1.80; 95% CI, 1.03 to 3.13). Subgroup analysis showed that odds of preeclampsia (P<0.01) and premature delivery (P<0.01) were higher in women with nondiabetic nephropathy compared with diabetic nephropathy, and the odds of preeclampsia (P=0.01) and premature delivery (P<0.01) were higher in women with macroproteinuria compared with microproteinuria. The median for follow-up time for renal events was 5 years (interquartile range, 5-14.7 years). There were no significant differences in the occurrence of renal events between CKD pregnant women and those without pregnancy (OR, 0.96; 95% CI, 0.69 to 1.35). Subgroup analysis showed that publication year, sample size, follow-up years, type of primary disease, CKD classification, level of serum creatinine at baseline, proteinuria, and level of systolic BP did not modify the renal outcomes. CONCLUSIONS The risks of adverse maternal and fetal outcomes in pregnancy are higher for women with CKD versus pregnant women without CKD. However, pregnancy was not a risk factor for progression of renal disease in women with CKD before pregnancy.

Abstract
OBJECTIVE Immunoglobulin A nephropathy (IgAN) exhibits a peak onset that coincides with the reproductive age. Therefore, many young women with IgAN may become pregnant. However, the outcome of pregnancy in women with renal diseases remains controversial, and the characteristics and outcome of pregnancy in IgAN patients must be further evaluated. METHODS A prospective follow-up study of 64 pregnant women with IgAN was performed by analyzing the laboratory data and prognosis. To clarify the influence of renal insufficiency, we compared these patients according to the chronic kidney disease (CKD) stage with special attention to CKD stage 3 [N=16 in total, N=9 for estimated glomerular filtration rate (eGFR) ≥45 mL/min, N=7 for <45 mL/min]. RESULTS We found that pregnancy and delivery did not produce any significant changes in the renal function for patients with CKD stage 3 (≥45 mL/min) at five years after delivery, although proteinuria was elevated at 30 weeks of pregnancy and at three months after delivery. However, only for patients with CKD stage 3 (<45 mL/min) was there a significant deterioration in the eGFR at five years after delivery. Additionally, the data of pregnant women with CKD stage 3 were compared with those of 22 nonpregnant women with similar clinical and demographic characteristics. CONCLUSION Pregnant patients with IgAN (CKD stage 3, eGFR ≥45 mL/min) did not exhibit any significant reduction in the renal function at five years after delivery as compared with the baseline, which was similar to the findings in nonpregnant patients. Thus, while pregnancy with CKD stage 3 (eGFR ≥45 mL/min) was not a risk factor, patients with CKD stage 3 (eGFR <45 mL/min) showed a worsened renal function five years after delivery.

Abstract
The prevalence of chronic kidney disease in women of childbearing age reaches approximately 0.2%. Under physiological conditions pregnancy results in important hemodynamic changes on the maternal organism. In the case of chronic kidney disease these adaptations often are only partial. Physiological changes of immune response during pregnancy may contribute to the progress of renal disease. Regardless of the underlying kidney disease, one can assume that the better the glomerular filtration rate and blood pressure are the more favorable the course of pregnancy will be with the chance for a healthy child and stable renal function. To achieve this goal, a close interaction is required between gynecologist, nephrologist, and other specialists in a center with appropriate experience.
