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
Introduction Women with kidney failure have impaired fertility and are at a higher risk of maternal and fetal morbidity and mortality. Little is known about pregnancies in women receiving maintenance home dialysis in the United States. Methods Using data from the United States Renal Data System (USRDS), a cohort of 26,387 women aged 15 to 49 years with kidney failure receiving maintenance home dialysis from 2005 to 2018 was examined. We calculated pregnancy rates and identified factors, including the modality associated with pregnancy receiving home dialysis. Results Overall, 437 pregnancies were identified in 26,837 women on home dialysis. The unadjusted pregnancy rate was 8.6 per 1000 person-years (PTPY). The unadjusted pregnancy rate was higher on home hemodialysis (16.0 vs. 7.5 PTPY) than on peritoneal dialysis. Women receiving home hemodialysis had a higher adjusted likelihood of pregnancy than women receiving peritoneal dialysis (hazard ratio [HR], 2.34; 95% confidence interval [CI], 1.79-3.05). Compared with women aged 20 to 24 years, the likelihood of pregnancy was lower in women aged 30 to 34 years (HR, 0.64; 95% CI, 0.43-0.96), 35 to 39 years (HR, 0.53; 95% CI, 0.35-0.79), 40 to 44 years (HR, 0.32; 95% CI, 0.21-0.49), and 45 to 49 years (HR, 0.21; 95% CI, 0.13-0.33). Whereas Black women had a higher likelihood of pregnancy (HR, 1.40; 95% CI, 1.07-1.83), there was no difference in likelihood of pregnancy in Asian, Hispanic, and Native Americans as compared to Whites. Body mass index, cause of kidney failure, socioeconomic status, rurality, predialysis nephrology care, or dialysis vintage were not significantly associated with pregnancy on home dialysis. Conclusion The pregnancy rate in women with kidney failure undergoing home dialysis is higher with home hemodialysis than with peritoneal dialysis. Younger age and Black race or ethnicity are associated with a higher likelihood of pregnancy among women receiving home dialysis. This information can guide clinicians in preconception counselling and making informed treatment decisions for pregnant women on home dialysis.

Abstract
Pregnancy is an important goal for many women with CKD or kidney failure, but important barriers exist, particularly as CKD stage progresses. Women with advanced CKD often have a limited fertility window and may miss their opportunity for a pregnancy if advised to defer until after kidney transplantation. Pregnancy rates in women with advanced kidney failure or receiving dialysis remain low, and despite the improved outcomes in recent years, these pregnancies remain high risk for both mother and baby with high rates of preterm birth due to both maternal and fetal complications. However, with increased experience and advances in models of care, this paradigm may be changing. Intensive hemodialysis regimens have been shown to improve both fertility and live birth rates. Increasing dialysis intensity and individualizing dialysis prescription to residual renal function, to achieve highly efficient clearances, has resulted in improved live birth rates, longer gestations, and higher birth weights. Intensive hemodialysis regimens, particularly nocturnal and home-based dialysis, are therefore a potential option for women with kidney failure desiring pregnancy. Global initiatives for the promotion and uptake of home-based dialysis are gaining momentum and may have advantages in this unique patient population. In this article, we review the epidemiology and outcomes of pregnancy in hemodialysis and peritoneal dialysis recipients. We discuss the role home-based therapies may play in helping women achieve more successful pregnancies and outline the principles and practicalities of management of dialysis in pregnancy with a focus on delivery of home modalities. The experience and perspectives of a patient are also shared.

Abstract
Fertility is known to be impaired more frequently in patients with chronic kidney disease than in the general population. A significant proportion of chronic kidney disease patients may therefore need Medically Assisted Reproduction. The paucity of information about medically assisted reproduction for chronic kidney disease patients complicates counselling for both nephrologists and gynaecologists, specifically for patients with advanced chronic kidney disease and those on dialysis or with a transplanted kidney. It is in this context that the Project Group on Kidney and Pregnancy of the Italian Society of Nephrology has drawn up these best practice guidelines, merging a literature review, nephrology expertise and the experience of obstetricians and gynaecologists involved in medically assisted reproduction. Although all medically assisted reproduction techniques can be used for chronic kidney disease patients, caution is warranted. Inducing a twin pregnancy should be avoided; the risk of bleeding, thrombosis and infection should be considered, especially in some categories of patients. In most cases, controlled ovarian stimulation is needed to obtain an adequate number of oocytes for medically assisted reproduction. Women with chronic kidney disease are at high risk of kidney damage in case of severe ovarian hyperstimulation syndrome, and great caution should be exercised so that it is avoided. The higher risks associated with the hypertensive disorders of pregnancy, and the consequent risk of chronic kidney disease progression, should likewise be considered if egg donation is chosen. Oocyte cryopreservation should be considered for patients with autoimmune diseases who need cytotoxic treatment. In summary, medically assisted reproduction is an option for chronic kidney disease patients, but the study group strongly advises extensive personalised counselling with a multidisciplinary healthcare team and close monitoring during the chosen medically assisted reproduction procedure and throughout the subsequent pregnancy.

Abstract
About 3% of pregnant women suffer from chronic kidney disease (CKD). This article reviews the literature on the outcomes of neonates born to mothers with CKD (including those undergoing dialysis and kidney transplantation), and the results show that CKD during pregnancy may increase the risk of preterm birth, low birth weight, and small for gestational age infant, but it does not increase the risk of congenital anomalies. As for long-term outcomes, CKD during pregnancy has no significant impact on offspring's physical development and immune function. Neurodevelopmental outcome of offspring is associated with preterm birth and low birth weight, rather than intrauterine drug exposure. However, further research and follow-up are needed to investigate the outcome of neonates born to mothers with CKD.

Abstract
Background Pregnant women with end-stage renal disease on chronic dialysis are at a high risk of maternal and foetal complications. Over the years, the prognosis of their pregnancies has improved with advances in dialysis treatments and maternal and neonatal care. We conducted this systematic review to examine the recent data on maternal and foetal outcomes in pregnant women with end-stage renal failure on chronic dialysis over the last decade. Methods We made a systematic review of studies on pregnant women on chronic dialysis published between 1 January 2010 and 31 December 2020. We searched the following electronic databases: Medline via PubMed, Embase and the Cochrane Library, with search strategies for each database. We checked the titles and abstracts identified by the search equation, and two independent reviewers assessed the articles retrieved. For each study, the two reviewers separately recorded the data from each selected article on a standardized data extraction form. For each article, we recorded relevant general information on the study, patient demographic characteristics, dialysis schedule, pregnancy complications and outcomes, maternal complications, and foetal and neonatal outcomes. Results The literature search yielded 1668 potentially relevant abstracts. After reviewing the titles, abstracts and full text, we identified 14 studies according to the inclusion criteria. All studies were observational, nine of them were retrospective and eight were from a single-centre experience. The total number of women included in these studies was 2364 (range 8-2008) and the total number of pregnancies was 2754 (range 8-2352). The patients' ages ranged from 15 to 45 years. Obesity was observed in 808 (34.2%) women and ranged from 1 to 778. Haemodialysis was the predominant modality with 2551 (92.6%) pregnancies, and 203 (7.4%) on peritoneal dialysis. Overall, 68 out of 402 (16.9%) spontaneous miscarriages, 21 out of 402 (5.2%) therapeutic abortions and 26 (8.3%) stillbirths among 313 (stillbirths and live births) were recorded. The mean or median gestational age at delivery ranged from 25.2 to 36 weeks. The main maternal complications were preeclampsia 11.9%, hypertension 7.7% and anaemia 3.9%. Live births represented 287 (71.4%) out of 402 pregnancies, birth weight ranged from 590 to 3500 g and preterm birth was the main, most common complication in all studies, ranging from 50% to 100%. Intrauterine growth restriction was present in 5.9% and small-for-gestational-age was reported in 18.9% of neonates. There were 22 (7.6%) neonatal deaths among 287 live births and 48 (15.3%) perinatal deaths among 313 total births (stillbirths and live births). Conclusions Presumably, considering the increase in the number of publications and the total number of pregnancies reported therein, the frequency of pregnancy in patients with end-stage chronic kidney disease treated by chronic dialysis has increased. However, the practice of treating pregnant women on dialysis differs significantly among countries. These findings highlight the need to standardize the definition of outcomes and healthcare for pregnant women on dialysis.

Abstract
Achieving parenthood can be an important priority for women and men with kidney failure. In recent decades, the paradigm has shifted toward greater support of parenthood, with advances in our understanding of risks related to pregnancy and improvements in obstetrical and perinatal care. This review, codesigned by people with personal experience of kidney disease, provides guidance for nephrologists on how to answer the questions most asked by patients when planning for parenthood. We focus on important issues that arise in preconception counseling for women receiving dialysis and postkidney transplant. We summarize recent studies reflecting pregnancy outcomes in the modern era of nephrology, obstetrical, and perinatal care in developed countries. We present visual aids to help clinicians and women navigate pregnancy planning and risk assessment. Key principles of pregnancy management are outlined. Finally, we explore outcomes of fatherhood in males with kidney failure.

Abstract
Background Evidence surrounding vascular access options for commencing dialysis in pregnancy complicated by chronic kidney disease (CKD) is limited. Creation of new arteriovenous fistulas (AVFs) in pregnant women is rare. Methods Retrospective cohort study of approaches to vascular access in pregnancy in centres in Australia, the United Kingdom (UK) and Canada (2002–2018). Results Twenty-three women with advanced CKD commenced dialysis in pregnancy (n = 20) or planned to commence (n = 3). Access at dialysis start was a tunnelled catheter (n = 13), temporary catheter (n = 1), AVF created pre-conception but used in pregnancy (n = 3) and AVF created during pregnancy (n = 3). No women commencing dialysis with an AVF required a catheter. No differences in perinatal outcomes were observed comparing AVFs and catheters at dialysis commencement. No AVFs were created in pregnancy in Canadian women. From Australia and the UK, 10 women had a new AVF created in pregnancy, at median gestation 14.5 weeks (IQR 12.5, 20.75). Four women still needed a catheter for dialysis initiation and 3 eventually used the new AVF. Six AVFs were successfully used in pregnancy at median gestation 24 weeks (IQR 22.5, 28.5), 2 were successfully created but not used and 2 had primary failure. No catheter-associated complications were identified except one episode of catheter-related sepsis. Conclusions Catheter-related complications were minimal. In selected women, with sufficient pre-planning, an AVF can be created and successfully used during pregnancy to minimise catheter use if preferred. Pre-conception counselling in advanced CKD should include discussing vascular access options reflecting local expertise and patient preferences. Graphic abstract ![]()

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
Sex and gender often are used interchangeably, but are two distinct entities, with sex being the biological attribute and gender including the social, psychological, and cultural aspects of one's identity. Kidney transplantation has been proven to be the best treatment for end-stage kidney disease, improving both quality of life and life-expectancy for most patients. However, gender disparities in access to and outcomes of kidney transplantation remain despite the plethora of evidence showing the advantages of kidney transplantation to our patients. Data have shown that women are less likely to be waitlisted for a kidney transplant and to receive a deceased donor or a living donor kidney. On the other hand, women are more likely than men to become living kidney donors. Although some state the latter is the result of the female gender to nurture and care for loved ones, others believe this observation is because women often are incompatible with their spouse or child because pregnancy is a strong sensitizing event, which stems from the biological rather than the social differences between the sexes. Influence of sex and gender is not limited to access to kidney transplantation, but rather exist in other areas of transplant medicine, such as the difference observed in transplant outcomes between the sexes, variability in immunosuppression metabolism, and even in more contemporary areas such as recent data showing sex-based differences in outcomes of kidney transplant recipients with coronavirus disease-2019, with males having an increased incidence of acute kidney injury and death.

Abstract
Dr Susan Hou began her illustrious nephrology career at a time when pregnancy in women with chronic kidney disease (CKD) was hazardous and actively discouraged. Her pioneering research in women's health provided much of the early outcome data that shaped our current understanding of CKD and pregnancy. Although many uncertainties regarding optimal management of this vulnerable patient group remain, recent decades have witnessed important advances and renewed interest in improving care for pregnant women with CKD. Many nephrologists have been inspired by Dr Hou's lifetime of work and are grateful for her generous collaborations. In this In Practice Review, we honor her legacy by providing an update of current literature and clinical management guidance in the context of a clinical case vignette that challenges us to consider the many complex aspects to the counseling and care of women with CKD who desire a pregnancy.

Pregnancy and delivery in women receiving maintenance hemodialysis in Japan: analysis of potential risk factors for neonatal and maternal complications. J Nephrol 2021; 34:1599-1609. [PMID: 34591251 PMCID: PMC8494660 DOI: 10.1007/s40620-021-01146-3] [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: 01/23/2021] [Accepted: 08/16/2021] [Indexed: 11/18/2022]
Abstract
Introduction Average dialysis vintage in Japan is among the longest in the world, providing a unique opportunity to characterize pregnancy under conditions of long dialysis vintage. In 2017, we carried out a nationwide survey following up on a similar survey in 1996, in which we investigated the prevalence and outcomes of pregnancy in women undergoing dialysis and assessed risk factors associated with neonatal and maternal complications. Methods The target population was women aged 15–44 years undergoing maintenance dialysis between 2012 and 2016. The survey was conducted in 2693 dialysis units. Results A response was obtained from 951 dialysis units, yielding a target population of 1992 women of childbearing age receiving hemodialysis or peritoneal dialysis. Pregnancy occurred only among women receiving hemodialysis, with 25 pregnancies (1.26% in 5 years) being reported for 20 women. Detailed information about 19 pregnancies (mean age 34.6 ± 5.7 years at conception, mean dialysis vintage 8.4 ± 7.3 years) indicated 4 spontaneous abortions, 1 elective abortion, no neonatal deaths, and 14 surviving infants, including 5 full-term (≥ 37 weeks at birth), 2 late preterm (34–36), and 3 extremely preterm (< 28) cases. Neonatal complications occurred in the offspring of 3 mothers who had end-stage renal disease (ESRD) caused by primary glomerulonephritis and serum albumin levels (sAlb) ≤ 3.2 mg/dL in the first trimester. These mothers had started dialysis at 12, 17, and 30 years of age. ESRD caused by diabetic nephropathy or primary glomerulonephritis, age at conception ≥ 38 years, and sAlb ≤ 3.2 mg/dL were associated with maternal complications, although not significantly. Conclusions In this study, the pregnancy rate of Japanese women with ESRD was 0.25% per year. The study generates the hypothesis that ESRD caused by diabetic nephropathy and age at conception ≥ 38 years are potential risk factors for maternal complications but not for neonatal complications in dialysis patients, and that hypoalbuminemia is a potential risk factor for both kinds of complications.

Kidney Transplant Outcomes in Indigenous People of the Northern Great Plains of the United States. Transplant Proc 2021; 53:1872-1879. [PMID: 34246475 DOI: 10.1016/j.transproceed.2021.05.003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/12/2021] [Accepted: 05/04/2021] [Indexed: 11/22/2022]
Abstract
BACKGROUND Indigenous people experience higher rates of end-stage renal disease as well as negative predictive factors that undermine kidney transplantation (KT) success. Despite these inequalities, data suggest that short-term outcomes are comparable to those of other groups, but few studies have examined this effect in the Northern Great Plains (NGP) region. METHODS We performed a retrospective database review to determine outcomes of KT in Indigenous people of the NGP. White and Indigenous people receiving a KT between 2000 and 2018 at a single center were examined. RESULTS A total of 622 KT recipients were included (117 Indigenous and 505 White). Indigenous patients were more likely to smoke, have diabetes, have higher immunologic risk, receive fewer living donor kidneys, and have longer waitlist times. In the 5 years after KT there were no significant differences in renal function, rejection events, cancer, graft failure, or patient survival. At 10 years posttransplant, Indigenous patients had twice the all-cause graft failure (odds ratio = 2.06; 95% confidence interval, 1.25-3.39) and half the survival rate (odds ratio = 0.47; 95% confidence interval, 0.29-0.76); however, this effect was not maintained once the effects of race, sex, smoking status, diabetes, preemptive transplant, high panel reactive antibody status, and transplant type were adjusted for. CONCLUSIONS KT outcomes in Indigenous patients in the NGP region are similar to those of White patients 5 years posttransplant, with differences emerging at 10 years that could be diminished with greater emphasis on correcting modifiable risk factors.

Abstract
AIM To review the incidence and management of anaemia and outcomes in pregnancies in a cohort of Australian women with chronic kidney disease. METHODS A retrospective audit of 63 pregnancies in 52 women with chronic kidney disease. RESULTS Sixty-eight percent of chronic kidney disease pregnancies were complicated by haemoglobin less than 100 g/L. Iron stores were measured in only 62% of all pregnancies. Serum ferritin was less than 100 ng/ml in 95% of those tested. Erythropoietin-stimulating agents were used in 24 pregnancies (38%). Intravenous iron was used in only nine non-dialysis pregnancies. CONCLUSION Greater awareness of the importance of regular measurement of iron stores and appropriate levels for repletion in chronic kidney disease pregnancies amongst health professionals involved in obstetric care may result in earlier detection and treatment of iron deficiency, and potentially improve maternal and fetal outcomes.

Factors influencing fertility rates in Australian women receiving kidney replacement therapy: Analysis of linked ANZDATA registry and perinatal data over 22 years. Nephrol Dial Transplant 2021; 37:1152-1161.

Abstract
BACKGROUND Pregnancy in women receiving kidney replacement therapy (KRT) is uncommon, and trends and factors influencing fertility rates remain poorly defined. METHODS The Australia and New Zealand Dialysis and Transplant Registry (ANZDATA) was linked to mandatory perinatal datasets (all births from 1991-2013, ≥20 weeks' gestation) in four Australian jurisdictions. Overall, age and era-specific fertility rates were calculated based on general and KRT population denominators. RESULTS From 2,948,084 births, 248 babies were born to 168 mothers receiving KRT (37 babies born to 31 dialysed mothers; 211 babies born to 137 transplanted mothers). Substantial agreement between ANZDATA and perinatal datasets was observed for birth events and outcomes. Transplanted women had higher fertility rates than dialysed women in all analyses, with 21.4 live births/1000 women/year (95% CI: 18.6-24.6) in transplanted women, 5.8 (95% CI: 4.1-8.1) in dialysed women and 61.9 (95% CI: 61.8-62.0) in the Non-KRT cohort. Fertility rates for dialysed women rose in recent years. After adjusting for maternal age and treatment modality, Caucasian women had higher fertility rates, while women with pre-existing diabetes, or transplanted women with exposure to KRT for ≤3.0 years had lower rates. As expected, transplanted women with a pre-conception estimated glomerular filtration rate (eGFR) of < 45 or transplant-to-pregnancy interval of < 1.0 year had lower fertility rates. Geographical location, socioeconomic status and primary disease (glomerulonephritis vs. other) did not affect fertility rates. CONCLUSIONS Reporting of births to ANZDATA is sufficiently accurate to justify ongoing data collection. Rising fertility rates in dialysed women may indicate permissive attitudes towards pregnancy. Treatment modality, ethnicity, diabetes, pre-conception eGFR, transplant-to-pregnancy interval and duration of KRT exposure were associated with fertility rates. These factors should be considered when counselling women with kidney disease about parenthood.

Abstract
Rationale & Objective Although end-stage kidney disease (ESKD) adversely affects fertility, pregnancies can occur among women receiving dialysis. ESKD increases the risk for adverse pregnancy outcomes and little is known about contraceptive use in women undergoing dialysis. Study Design Retrospective cohort study. Setting & Participants Using the US Renal Data System covering January 1, 2005, through December 31, 2014, we evaluated for each calendar year women who for the entire year were aged 15 to 44 years, receiving dialysis, and with Medicare as the primary payer. Predictors Age, race/ethnicity, and calendar year of prevalent ESKD. Outcome Contraceptive use. Analytic Approach We determined rates of contraceptive use and used multivariable logistic regression to identify factors associated with contraceptive use. Results The study cohort included 35,732 women and represented 115,713 person-years. The rate of contraceptive use was 5.30% of person-years (95% CI, 5.17%-5.42%). Overall, contraceptive use increased from 2005 to 2014 (4.21%; 95% CI, 3.84%-4.59% vs 6.54%, 95% CI, 6.10%-6.99%). Compared with women aged 25 to 29 years, contraceptive use was higher in women aged 15 to 24 years (OR, 1.30; 95% CI, 1.18-1.43) and lower in women aged 30 to 34 years (OR, 0.74; 95% CI, 0.68-0.81), 35 to 39 years (OR, 0.46; 95% CI, 0.42-0.50), and 40 to 44 years (OR, 0.30; 95% CI, 0.27-0.34). Compared with White women, contraceptive use was higher in Black (OR, 1.12; 95% CI, 1.02-1.24) and Native American women (OR, 1.60; 95% CI, 1.25-2.05). Women with ESKD due to glomerulonephritis had a higher likelihood of contraceptive use than women with ESKD due to diabetes (OR, 1.22; 95% CI, 1.06-1.42). Women receiving peritoneal dialysis had a lower likelihood of contraceptive use than women receiving hemodialysis (OR, 0.85; 95% CI, 0.78-0.93). Compared with women without predialysis nephrology care, contraceptive use was higher in women who received predialysis nephrology care for 12 or fewer months (OR, 1.22; 95% CI, 1.09-1.37) and more than 12 months (OR, 1.33; 95% CI, 1.20-1.47). Limitations Retrospective design and use of administrative data. Conclusions Among women with ESKD undergoing dialysis, contraceptive use remains low at 5.30%. Younger age, Native American and Black race/ethnicity, ESKD due to glomerulonephritis, hemodialysis, and predialysis nephrology care are associated with a higher likelihood of contraceptive use. The study highlights the importance of prepregnancy counseling for contraceptive use in women receiving dialysis.

Abstract
Sexual health is inversely associated with estimated glomerular filtration rate and is associated with adverse cardiovascular outcomes, depression, poor self-image, and impaired quality of life. Many women with chronic kidney disease (CKD) and ESKD experience symptoms of sexual dysfunction which is underrecognized secondary to a variety of factors including physicians' discomfort in discussing sexual health, patients' reluctance to bring up sexual health, difficulty in the assessment of sexual health in comparison to men, and the overall lack of well-conducted clinical studies in women. The pathophysiology is not fully understood but likely involves changes in sex hormones throughout the hypothalamic-pituitary-ovarian axis. Proper evaluation of this axis is necessary as treatment is tailored to these findings and can improve outcomes. A comprehensive assessment of sexual dysfunction inclusive of women with varying gender identification and sexual orientation, partnered with recognition and treatment of contributing factors as well as identifying the underlying cause, is paramount. With the lack of studies, particularly in women with CKD, treatment options, in some cases, can be considered unchartered territory. In this article, we will review available evidence on the pathophysiology, clinical manifestations, and treatment for sexual dysfunction in women with CKD and ESKD.

Abstract
End-stage kidney disease is associated with low fertility, with rates of conception in women on dialysis estimated at 1/100th of the general population. However, live birth rates are increasing over time in women on hemodialysis, whereas they remain lower and static in women on peritoneal dialysis. Intensification of hemodialysis, targeting a serum blood urea nitrogen <35 mg/dL or 36 hours of dialysis per week in women with no residual kidney function, is associated with improved live birth rates and longer gestational age. Even in intensively dialyzed cohorts, rates of prematurity and need for neonatal intensive care are high, upwards of 50%. Although women on peritoneal dialysis in pregnancy do not appear to be at increased risk of delivering preterm compared with those on hemodialysis, their infants are more likely to be small for gestational age. As such, hemodialysis has emerged as the preferred dialysis modality in pregnancy. Provision of specialized nephrology, obstetric, and neonatal care is necessary to manage these complex pregnancies and family planning counseling should be offered to all women with end-stage kidney disease.

Abstract
Women with end-stage kidney disease commonly have difficulty conceiving through spontaneous pregnancy, and many suffer from infertility. Kidney transplantation restores the impairment in fertility and increases the possibility of pregnancy. In addition, the number of female kidney transplant recipients of reproductive age has been increasing. Thus, preconception counseling, contraceptive management, and family planning are of great importance in the routine care of this population. Pregnancy in kidney transplant recipients is complicated by underlying maternal comorbidities, kidney allograft function, the effect of pregnancy on the transplanted kidney, and the effect of the maternal health on the fetus, in addition to immunosuppressive medications and their potential teratogenesis. Given the potential maternal and fetal risks, and possible complications during pregnancy, pretransplant and prepregnancy counseling for women of reproductive age are crucial, including delivery of information regarding contraception and timing for pregnancy, fertility and pregnancy rates, the risk of immunosuppression on the fetus, the risk of kidney allograft, and other maternal complications. In this article, we discuss aspects related to pregnancy among kidney transplant recipients and their management.

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
BACKGROUND AND OBJECTIVES AKI requiring dialysis is a contributor to the growing burden of kidney failure, yet little is known about the frequency and patterns of recovery of AKI and its effect on outcomes in patients on incident dialysis. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS Using the US Renal Data System, we evaluated a cohort of 1,045,540 patients on incident dialysis from January 1, 2005 to December 31, 2014, retrospectively. We examined the association of kidney failure due to AKI with the outcome of all-cause mortality and the associations of sex and race with kidney recovery. RESULTS Mean age was 63±15 years, and 32,598 (3%) patients on incident dialysis had kidney failure due to AKI. Compared with kidney failure due to diabetes mellitus, kidney failure attributed to AKI was associated with a higher mortality in the first 0-3 months following dialysis initiation (adjusted hazard ratio, 1.28; 95% confidence interval, 1.24 to 1.32) and 3-6 months (adjusted hazard ratio, 1.16; 95% confidence interval, 1.11 to 1.20). Of the patients with kidney failure due to AKI, 11,498 (35%) eventually recovered their kidney function, 95% of those within 12 months. Women had a lower likelihood of kidney recovery than men (adjusted hazard ratio, 0.86; 95% confidence interval, 0.83 to 0.90). Compared with whites, blacks (adjusted hazard ratio, 0.68; 95% confidence interval, 0.64 to 0.72), Asians (adjusted hazard ratio, 0.82; 95% confidence interval, 0.69 to 0.96), Hispanics (adjusted hazard ratio, 0.82; 95% confidence interval, 0.76 to 0.89), and Native Americans (adjusted hazard ratio, 0.72; 95% confidence interval, 0.54 to 0.95) had lower likelihoods of kidney recovery. CONCLUSIONS Kidney failure due to AKI confers a higher risk of mortality in the first 6 months compared with kidney failure due to diabetes or other causes. Recovery within 12 months is common, although less so among women than men and among black, Asian, Hispanic, and Native American patients than white patients.

Abstract
Background A positive pregnancy test in acute or chronically ill patients has implications for the use of potentially mutagenic or teratogenic products in urgent medical therapies such as the use of chemotherapies or therapies with immunosuppressants, for anesthesia, and for time-sensitive indications like urgent surgery or organ Transplantation. Despite a lack of evidence, it is currently believed that human chorionic gonadotropin serum concentrations are always elevated in female dialysis patients even without pregnancy. It is also believed that human chorionic gonadotropin cannot be used to confirm or exclude pregnancy. Methods Human chorionic gonadotropin was examined in female dialysis patients (18–50 years of age), and was classified as positive above 5 mlU/ml. In addition, fertility status was determined. For an enhanced index test, the cut-off of 5 mIU/ml was used for potentially fertile patients and 14 mIU/ml for infertile patients to calculate diagnostic test accuracy. The ideal cut-off for human chorionic gonadotropin was estimated using Liu’s method with bootstrapped 95% confidence intervals. Predictors of human chorionic gonadotropin increase were analyzed using multivariable linear regression. Results Among 71 women, two (2.8%) were pregnant, 46 (64.8%) potentially fertile, and 23 (32.4%) infertile. We observed human chorionic gonadotropin concentrations > 5 mIU/ml in 10 patients, which had a sensitivity of 100% (95% confidence interval: 100 to 100), a specificity of 86% (95% confidence interval: 77 to 94), a positive predictive value of 17% (95% confidence interval: 8 to 25) and a negative predictive value of 100% (95% confidence interval: 100 to 100) for the diagnosis of pregnancy. Using a cut-off > 14 mIU/ml for infertile patients or the exclusion of infertile patients increased specificity to 93% or 98%, respectively. The ideal cut-off was 25 mIU/ml (95% confidence interval: 17 to 33). Pregnancy and potential fertility, but not age, were independent predictors of human chorionic gonadotropin. Conclusion Human chorionic gonadotropin is elevated > 5mIU/ml in 14.5% of non-pregnant dialysis patients of child-bearing age. In potentially fertile women, this cut-off can be used to exclude pregnancy. In case of an unknown fertility status, the ideal human chorionic gonadotropin cut-off was 25 mIU/ml.

Abstract
BACKGROUND Acute kidney injury (AKI) during pregnancy is a public health problem and is associated with maternal and fetal morbidity and mortality. Clinical outcomes and health care utilization in pregnancy-related AKI, especially in women with diabetes, are not well studied. METHODS Using data from the 2006 to 2015 Nationwide Inpatient Sample, we identified 42,190,790 pregnancy-related hospitalizations in women aged 15-49 years. We determined factors associated with AKI, including race/ethnicity, and associations between AKI and inpatient mortality, and between AKI and cardiovascular (CV) events, during pregnancy-related hospitalizations. We calculated health care expenditures from pregnancy-related AKI hospitalizations. RESULTS Overall, the rate of AKI during pregnancy-related hospitalizations was 0.08%. In the adjusted regression analysis, a higher likelihood of AKI during pregnancy-related hospitalizations was seen in 2015 (OR 2.20; 95% CI 1.89-2.55) than in 2006; in older women aged 36-40 years (OR 1.49; 95% CI 1.36-1.64) and 41-49 years (OR 2.12; 95% CI 1.84-2.45) than in women aged 20-25 years; in blacks (OR 1.52; 95% CI 1.40-1.65) and Native Americans (OR 1.45; 95% CI 1.10-1.91) than in whites, and in diabetic women (OR 4.43; 95% CI 4.04-4.86) than in those without diabetes. Pregnancy-related hospitalizations with AKI were associated with a higher likelihood of inpatient mortality (OR 13.50; 95% CI 10.47-17.42) and CV events (OR 9.74; 95% CI 9.08-10.46) than were hospitalizations with no AKI. The median cost was higher for a delivery hospitalization with AKI than without AKI (USD 18,072 vs. 4,447). CONCLUSION The rates of pregnancy-related AKI hospitalizations have increased during the last decade. Factors associated with a higher likelihood of AKI during pregnancy included older age, black and Native American race/ethnicity, and diabetes. Hospitalizations with pregnancy-related AKI have an increased risk of inpatient mortality and CV events, and a higher health care utilization than do those without AKI.
