Abstract
AIM To describe pregnancy outcome of kidney transplant patients till 1 year postpartum. METHODS This retrospective, monocentric study included 15 kidney transplant patients who presented 18 pregnancies, between January 2000 and January 2020. For each of them, we searched for possible obstetrical, fetal and renal complications and we evaluated renal function before, during and after pregnancy. RESULTS The live birth rate was 84% (16/19) with an average gestational age at delivery of 37 weeks of gestation. The rate of prematurity was 50% (8/16), gestational diabetes was 16.6% (3/18) and preeclampsia was 27.7% (5/18). Cesarean section was performed in 61.1% (11/18) of cases including, 81.8% (9/11) unplanned surgery. The average birth weight was 2635 grams and 37.5% (6/16) of the newborn were small for gestational age. All patients had stable renal function before conception of pregnancy. We noticed two acute graft rejection during pregnancy with only one resulting in graft loss. Four patients had a reduced graft function in 12months of the postpartum. CONCLUSION Risk of maternal, fetal and renal complications remained high in kidney transplant recipients. Pregnancy should be carefully planned in transplanted women associated with adequate follow-up according to clinical guidelines (normal renal function and blood pressure without proteinuria before pregnancy, no recent graft rejection, period of one year after transplant respected and no teratogenic treatment in the month before pregnancy).

Acute Kidney Injury in Pregnant Patient With Pancreas-Kidney Transplant Caused by Abdominal Compartment Syndrome: A Case Presentation, Review of Literature, and Proposal of Diagnostic Approach. Can J Kidney Health Dis 2019; 6:2054358119861942.

Abstract
Rationale: With increasing number of complex medical patients with renal transplant who get pregnant, clinicians need to be aware of abdominal compartment syndrome which may masquerade as acute renal allograft injury in pregnancy. Presenting concerns of the patient: A 34-year-old nulliparous Caucasian female with end-stage renal disease (ESRD) due to type 1 diabetes mellitus who received a simultaneous pancreas-kidney transplant (SPK) in 2006 and then after rejection of renal allograft another, kidney-only allograft from a donation after circulatory death became pregnant in May 2013 with dichorionic, diamniotic twins without reproductive technology, and during pregnancy, she developed two episodes of acute injury to the renal allograft. Diagnoses: End-stage renal disease secondary to type I diabetes, acute renal allograft injury, tacrolimus toxicity, abdominal pain. Interventions (including prevention and lifestyle): She received intravenous hydration, medications contributing to renal failure were held, and pain and nauseas were controlled appropriately. Abdominal compartment syndrome was managed by maintaining intravascular pressure and optimizing regional and systemic vascular perfusion by appropriate fluid balance, evacuating intraluminal contents by decompressing gastrointestinal system, and improving abdominal wall compliance by using appropriate analgesics, sedation, and patient positioning. Outcomes: With advancing pregnancy, the patient developed progressive abdominal pain, nausea, leg edema, and rising creatinine that were not responsive to ongoing therapies and required delivery via Cesarean section at 31 weeks of gestational age. Lessons learned: In the era of increasing number of pregnant renal transplant patients with multiple medical issues, we need organized approach to diagnosis of acute renal allograft injury in pregnancy and we need to consider abdominal compartment syndrome as one of the causes.

Abstract
BACKGROUND Women suffering from kidney disease are more prone to fertility problems, due to uremia. Fortunately, their fertility rate increases dramatically after renal transplantation. This study analyzes the predictors/risk factors of successful pregnancy with live birth outcome while presenting an overview of the 7-year experience of a single center. METHODS This retrospective cohort study includes 239 women of reproductive age (18-40 years) who underwent renal transplantation in a tertiary Turkish clinic between October 1, 2011, and August 24, 2017. The subjects were invited to take part in a survey questioning their obstetric characteristics and they were assessed in 2 groups: fertile and infertile. Multivariable linear regression analysis was conducted to determine the predictors of a successful pregnancy. RESULTS Thirty-five 35 patients wished to become pregnant: 12 got pregnant spontaneously, while 21 failed to become pregnant (spontaneously). The mean age of the patients at the survey was 34 ± 7. Regular menstrual cycles after renal transplantation, tacrolimus-mycophenolate mofetil maintenance protocol, and age at transplantation were found to be predictors of spontaneous pregnancy. The duration of peritoneal dialysis was significantly longer in the infertile group (48 vs 12 months). CONCLUSION End-stage renal disease's negative impacts, including menstrual abnormality and fertility problems, can be overcome by successful kidney transplantation with appropriate immunosuppression. Minimizing the duration of peritoneal dialysis, particularly in patients who desire future fertility, may be accepted as a logical management strategy.

Abstract
Objective To obtain information on menstrual patterns before and after transplantation, desire for future pregnancy, and use of contraception among premenopausal kidney transplant recipients. Study Design This observational study collected information using self-administered anonymous questionnaires during a routine outpatient clinic visit. Results Of the 107 women who completed the questionnaire, 41 identified themselves as being premenopausal. Among the 41 premenopausal women, approximately half of the women reported their current menstrual patterns as normal and 26% were not using any form of contraception. Overall, 10 women (24%) reported a desire to become pregnant and 4 women (10%) had a successful pregnancy after transplantation. Most of the women who desired a future pregnancy (8/10) were receiving an immunosuppressive regimen that included mycophenolate mofetil. Conclusion Kidney transplantation in the current era is associated with a return of normal menstrual function in the majority of female transplant recipients. A substantial fraction of women desire pregnancy after transplantation and many are using an immunosuppressive drug with limited safety data on use during pregnancy. More caution should be used with the use of newer immunosuppressive agents in sexually active premenopausal transplant recipients until more safety data are available.

Abstract
Management of the pregnant woman with chronic kidney disease is difficult for both nephrologists and obstetricians. Prepregnancy counselling with respect to risk stratification, optimization of maternal health prior to pregnancy, as well as management of the many potential pregnancy-associated complications in this complex patient population remains challenging due to the paucity of large, well-designed clinical studies. Furthermore, the heterogeneity of disease and the relative infrequency of pregnancy, particularly in more advanced stages of chronic kidney disease, leaves many clinicians feeling ill prepared to manage these pregnancies. As such, counselling is imprecise and management varies substantially across centers. All pregnancies in women with chronic kidney disease can benefit from a collaborative multidisciplinary approach with a team that consists of nephrologists experienced in the management of kidney disease in pregnancy, maternal-fetal medicine specialists, high-risk pregnancy nursing staff, dieticians, and pharmacists. Further access to skilled neonatologists and neonatal intensive care unit support is essential given the risks for preterm delivery in this patient population. The goal of this paper is to highlight some of the data that currently exist in the literature, provide management strategies for the practicing nephrologist at all stages of chronic kidney disease, and explore some of the knowledge gaps where future multinational collaborative research efforts should concentrate to improve pregnancy outcomes in women with kidney disease across the globe.

Abstract
Fertility in women with kidney failure is restored by transplantation. It requires careful planning and is only advisable in women with good kidney function, controlled blood pressure, and general good health. Immunosuppressive drugs carry risks for the fetus, but the risks of prednisone, azathioprine, cyclosporine, and tacrolimus are surprisingly low. Mycophenolate is teratogenic. The success rate for pregnancy in kidney transplant recipients is lower than in the general population with 70% to 80% of pregnancies resulting in surviving infants. Prematurity, intrauterine growth restriction, and preeclampsia are all increased. Complications are higher and outcomes are worse for women with serum creatinine levels over 1.3 mg/dL. Ten to 15% of women have a temporary or permanent decline in kidney function, particularly if prepregnancy creatinine is high. Transplant-related infections can be serious for the mother and fetus. A multidisciplinary team should coordinate care.

Abstract
The 2009 Kidney Disease: Improving Global Outcomes (KDIGO) clinical practice guideline on the monitoring, management, and treatment of kidney transplant recipients is intended to assist the practitioner caring for adults and children after kidney transplantation. The guideline development process followed an evidence-based approach, and management recommendations are based on systematic reviews of relevant treatment trials. Critical appraisal of the quality of the evidence and the strength of recommendations followed the Grades of Recommendation Assessment, Development, and Evaluation (GRADE) approach. The guideline makes recommendations for immunosuppression, graft monitoring, as well as prevention and treatment of infection, cardiovascular disease, malignancy, and other complications that are common in kidney transplant recipients, including hematological and bone disorders. Limitations of the evidence, especially on the lack of definitive clinical outcome trials, are discussed and suggestions are provided for future research.

Abstract
The National Transplantation Pregnancy Registry (NTPR) was established in 1991 to study the outcomes of pregnancies in female transplant recipients and pregnancies fathered by male transplant recipients. Data from the NTPR have helped to endorse the reassurances from publications of smaller experiences that successful pregnancies are possible in the transplant population. In our last review for this journal (2000), we noted that important future issues would include the reassessment of prepregnancy guidelines, gestational and organ-specific problems, the role of new immunosuppressive drugs, and the long-term effects of pregnancy on both graft and child. Data collected by the NTPR over the last 7 years have addressed these issues, thus providing additional information for health care providers of transplant recipients of childbearing age. There has been some refinement of prepregnancy guidelines, but there is a need for additional data collection so that organ-specific outcomes and risks can further be identified. To date, the outcomes of the children followed have been encouraging, and specific remote effects have not been identified, but continued surveillance is still vital. Of special concern are the new immunosuppressive drugs, specifically for mycophenolate mofetil (CellCept, Roche Laboratories Inc., Nutley, New Jersey), where data reported to the NTPR and through postmarketing surveillance have shown an increased incidence of nonviable outcomes and a specific pattern and increased incidence of malformation in the newborn, which has resulted in a pregnancy category change. Newer information points to an increased need for vigilance among centers and continued monitoring of pregnancy outcomes in this population. As the first reported pregnancy after transplantation occurred in a kidney recipient 50 years ago, in March 1958, this review also highlights the first reported pregnancies in other solid organ recipients.

Abstract
BACKGROUND To identify factors related with successful pregnancy in renal transplant recipients and the effect of pregnancy on long-term graft outcome. METHODS The study group consisted of 48 women who conceived after undergoing renal transplantation (total pregnancies 74). The control group consisted of 187 nonpregnant female renal transplant recipients. RESULTS Mean ages at the time of transplantation and pregnancy were 28.0+/-4.0 years and 31.6+/-4.1 years, respectively. The mean interval from transplantation to pregnancy was 40.2+/-27.1 months. Outcomes included 49 live births, 12 terminations, 9 miscarriages, 3 stillbirths, and 1 ectopic pregnancy. Eleven of the 74 pregnancies (15%) were within 1 year of transplantation, resulting in seven live births, two miscarriages, and two terminations. Live births were associated with younger age at the time of transplantation (relative risk, 0.75; P=0.042) and younger age at the time of pregnancy (relative risk, 0.76; P=0.022). Graft failure rate from transplantation to end of follow-up did not differ between the pregnant and nonpregnant groups (19% vs. 21%, P=0.688). The 10-year graft survival rates were also similar in the 11 women who became pregnant less than or equal to 12 months after transplantation and the 37 who became pregnant more than 12 months after transplantation (78.8% vs. 78.6%, P=0.941). CONCLUSION A younger age at transplantation and at pregnancy was associated with a greater likelihood of a live birth. Transplantation to conception interval of less than 1 year was not associated with a greater number of adverse pregnancy events when compared with the group with transplantation to conception interval greater than 1 year.

Abstract
Reproductive success is a common, expected outcome for male and female recipients of solid-organ transplants. Men can father children, and women can become pregnant and carry the fetus to delivery. There are, however, important maternal and fetal complications that need to be considered to provide optimal care to the mother and her infant. Although pregnancy is common after the transplantation of all solid organs, guidelines for optimal counseling and clinical management are limited. This review discusses information to help the physician counsel the kidney transplant recipient about risks of pregnancy for the mother and the fetus and provides information to help guide treatment of the pregnant transplant recipient.

Abstract
Endocrine abnormalities are common in patients with chronic kidney disease (CKD) and lead to sexual dysfunction, anemia, hyperparathyroidism, and altered mineral metabolism. Common clinical problems include disturbances in menstruation in women, erectile dysfunction in men, and decreased libido and infertility in both sexes. Organic factors tend to be prominent and are related to uremia and other comorbid illnesses. Psychological factors and depression may exacerbate the primary problem. Alterations in the hypothalamic-pituitary axis are seen early in CKD and tend to worsen after patients start dialysis. Hypogonadism plays a dominant role in male sexual function, whereas changes in hypothalamic-pituitary function predominate in female sexual dysfunction. In patients on dialysis, treatment strategies include optimizing dose of dialysis, correction of anemia with erythropoietin, and correction of hyperparathyroidism. Successful kidney transplantation may restore normal sexual function, especially in younger patients.

Abstract
Kidney transplant improves reproductive function; planning for pregnancy is crucial. Prenatal management must address potential fetal complications: preterm delivery, intrauterine growth restriction, low birth weight; as well as maternal: hypertension, preeclampsia, gestational diabetes, acute rejection or graft loss. The latter depends upon timing after transplant, prepregnancy kidney function, and continuation of immunosuppressive agents at appropriate levels. Graft function is not adversely affected if preconception kidney function was normal. Acute rejection, 9%-14%, must be immediately addressed, with kidney biopsy if necessary. Blood pressure should be meticulously managed; serious morbidity results from poor control. Blood pressures >130/80 mmHg require acceptable antihypertensives: beta-blockers, alpha-methyldopa, hydralazine, and calcium channel blockers. Preeclampsia requires seizure prophylaxis with magnesium sulfate, with expeditious delivery. Screening for urinary tract infections with aggressive treatment and for opportunistic infections that may affect the fetus is essential. Surveillance for fetal anomalies, growth, and antenatal testing is important. Steroids for fetal lung maturity are indicated for preterm delivery. Vaginal birth is preferred, reserving cesarean for obstetrical indications, with pain management similar to normal laboring patients. Surveillance for infection postpartum is warranted. Conflicting information exists regarding safety of breastfeeding with immunosuppressive drugs; immunosuppressive medication must be adjusted to prepregnancy levels and contraception counseling addressed.

Abstract
BACKGROUND There are limited data on the effect of pregnancy on long-term renal allograft function. The aim of the study was to compare long-term graft and patient outcome between pregnant and nonpregnant women after renal transplantation. METHODS The study group consisted of 39 women attending the Perinatal Division of the Rabin Medical Center who conceived after undergoing renal transplantation (total number of live births: 55). All had a functioning allograft at the time of conception. Each patient was matched with 3 controls for 12 factors known to affect graft survival. The controls were derived from a cohort of 250,000 transplant patients registered in the Collaborative Transplantation Study (CTS) database. The groups were compared for graft survival, long-term patient survival, and kidney function (CTS clinical grading scale). RESULTS Graft (61.6%) and patient (84.8 %) survival from transplantation to the end of follow-up (15 years) in the women who conceived after transplantation did not differ from the rates observed in the 177 women in the matched control group (68.7% and 78.8 %, respectively). There were no between-group differences in long-term graft function. CONCLUSION Pregnancy does not appear to have adverse effects on long-term graft or patient survival or kidney function in women after renal transplantation.

Abstract
In order to investigate the effect of different immunosuppressive regimens and the time interval between transplantation and pregnancy on long-term outcome, we performed a case-control study in pregnant renal allograft recipients. Eighty-one pregnancies of kidney transplanted recipients were identified [cyclosporine (CYA): n = 40; azathioprine (AZA): n = 41]. Controls were matched with respect to important prognostic factors. Posttransplant follow-up was 91.3 +/- 5 months. Graft and patient survival were similar in both groups and there was no apparent effect of immunosuppression. A total of 28 recipients (33%) delivered within 2 years and 6 (8%) subjects within 1 year after transplantation, but these short transplantation-to-pregnancy intervals had no apparent adverse effect on long-term outcome. In contrast to AZA-treated patients, CYA-treated patients experienced an increase in serum creatinine postpartum (1.15 +/- 0.2 mg/dL vs. 1.61 +/- 0.1 mg/dL; p < 0.05). Whole blood CYA levels decreased transiently during pregnancy from 115.9 +/- 8 ng/mL to 80.7 +/- 7 ng/mL leading to a gradual increase in drug dose from 240 +/- 14 mg/day to 324 +/- 21 mg/day (p < 0.05). Following delivery, there was an increase in CYA concentrations to 173 +/- 5.4 ng/mL, requiring rapid dose tapering to baseline of 246 +/- 15 mg/day. Pregnancies in renal recipients do not affect long-term patient and graft survival, independent of the immunosuppression. No detrimental effect of short transplantation-to-pregnancy intervals on long-term graft function was detected.

Abstract
Little is known about the implications of performing a renal transplant on a patient who is already pregnant. This case study reports a successful outcome of pregnancy, diagnosed coincidentally following renal transplantation at 13 weeks gestation. The recipient was a 23-year-old woman with chronic kidney disease who received a live-related renal transplant from her father. Pregnancy was discovered at routine ultrasound scanning of the renal allograft at 5 days posttransplant and estimated at 13 weeks gestation. She received ciclosporin monotherapy as immunosuppression throughout the pregnancy, and was given valacyclovir as prophylaxis against cytomegalovirus (CMV) infection. Renal function remained stable throughout the pregnancy, which progressed normally, resulting in the vaginal delivery of a healthy, liveborn male infant at 37 weeks gestation. This case study demonstrates that transplantation during pregnancy can have a successful outcome.

Abstract
INTRODUCTION This study reviewed the course of pregnancies in terms of impact on renal function and delivery-related data among women who received kidney transplants in our unit. METHODS We reviewed the medical records of women transplanted between 1982 and 2002 who became pregnant. We recorded the data of medical, obstetrical, and transplant-related complications, plasma creatinine levels, and blood pressures at baseline, delivery, and 12 months after delivery. RESULTS Thirty women had 37 pregnancies. Immunosuppressive protocols included cyclosporine, ketoconazole, azathioprine, and prednisone in 22 patients or azathioprine and prednisone in 15. Renal function decreased significantly: mean creatinine levels at baseline, delivery, and after 1 year were: 1.19 +/- 0.38 mg/dL; 1.44 +/- 0.70 mg/dL; and 1.38 +/- 0.53 mg/dL, respectively (P = .023 and P = .004 vs baseline respectively). Systolic and diastolic blood pressures at delivery were higher than at baseline (134 +/- 19 and 86 +/- 14 mm Hg vs 126 +/- 21 and 79 +/- 13 mm Hg (P = .029 and P = .053, respectively). These values normalized 1 year later (128 +/- 21 and 80 +/- 16). Decreased use of antihypertensive drugs were the cause of poor blood pressure control (1.8 +/- 1.3 vs 0.9 +/- 0.7, P < .01). Blood pressure control improved following delivery. The most frequent complications were preeclampsia (18.9%), intrahepatic cholestasis (13.5%), and urinary tract infections (13.5%). There were five rejection episodes. Seven miscarriages took place and one mole. Eleven pregnancies were uncomplicated. CONCLUSION Renal transplantation is the best treatment for fertile women with end-stage renal disease who want to become pregnant. However, pregnancy is risky for the mother, fetus, newborn, and allograft.

Abstract
BACKGROUND Animal work indicates that ovarian hormones are important in initiating and maintaining enhanced renal function in pregnant rats and that a renal response resembling pregnancy can be provoked in male rats exposed to pregnancy hormones. Women becoming pregnant following renal transplantation provide an opportunity to compare the functional response of male and female allografts to the gestational endocrine environment. METHODS This retrospective observational study included 20 renal allograft recipients (age 29.7 +/- 2.4 yrs) (mean +/- SE) who had 22 pregnancies beyond 24 weeks (gestation at delivery 35.5 +/- 0.6 weeks). Donor characteristics, transplant details, renal follow-up data, and information about pregnancy and allograft function were obtained from hospital notes. RESULTS Thirteen women received male allografts (donor age 30.0 +/- 3.9 years) (mean +/- SEM) and 7 women, female allografts (donor age 45.1 +/- 6.0 years) (P = .04). There were no significant differences between the two groups in maternal recipient age, transplant to pregnancy interval, antenatal complications, pregnancy outcome, or postnatal graft function. Compared to prepregnancy values serum creatinine (SCr) decrements and augmented 24-hour creatinine clearance (CrCl) were observed over the first trimester in both male and female allografts: Delta CrCl from 106.8 +/- 13.2 mL/min to 114.4 +/- 11.4 mL/min (35.6% increase) and 71.8 +/- 7.4 to 89.5 +/- 11.3 mL/min (24.7% increase), respectively, and Delta SCr from 90.1 +/- 5.4 micromol/L to 73.6 +/- 6.6 micromol/L (17.8% decrease) and 99.8 +/- 9.7 micromol/L to 78.0 +/- 5.7 micromol/L (13.5% decrease), respectively. Differences between the two groups did not reach statistical significance. CONCLUSIONS Donor gender and/or age do not appear to influence the gestational renal response in kidney transplant recipients.

Abstract
BACKGROUND For women with end-stage renal failure of child-bearing age, renal transplantation offers a chance to start a family. Pregnancies in renal transplant recipients involve risks for graft and fetus, and need to be carefully managed. AIM To identify graft, fetal and maternal outcomes in our patients, and compare our results with those of the large national transplant registries. DESIGN Retrospective case-note review. METHODS We assessed the outcomes of 48 pregnancies in 24 renal transplant recipients. Obstetric data and renal parameters were examined in 27-30 pregnancies that progressed to delivery. RESULTS Mean time from transplantation to pregnancy was 6.5 years, with an unfavourable outcome in patients who conceived within 1 year. There was a 41% incidence of fetal growth restriction (FGR), and 33% of infants were small for gestational age. FGR was associated with maternal hypertension, a pre-pregnancy serum creatinine (SCr) >/= 133 micro mol/l (1.5 mg/dl), calcineurin inhibitors and the use of cardioselective beta blockers. Two patients with pre-pregnancy SCr > 200 micro mol/l lost their grafts within 3 years of delivery. A permanent significant decline in graft function occurred in 20%, by 6 months post delivery. DISCUSSION FGR with SGA infants occurs frequently. Atenolol should be avoided in pregnancy and Metoprolol should not be combined with calcineurin inhibitors. Pregnancy appeared to have a deleterious effect on graft function in patients with SCr > 155 micro mol (1.75 mg/dl). Patients with pre-pregnancy SCr 200 micro mol/l are at greatest risk.

Abstract
Successful pregnancy outcomes are possible after all types of solid organ transplantation and thousands of successful pregnancies in such women have been reported. As immunosuppressive medications are required to maintain adequate graft and maternal survival, major concerns are the effect of these agents on the fetus and the effect of pregnancy on the well being of mother and graft, against a background of continuing advances and modifications in immunosuppressive therapy. Women should avoid unnecessary medications during pregnancy but clinicians worry most about teratogens; agents (environmental, pharmaceuticals or other chemicals) that cause abnormal development, whether this be an overt structural birth defect or more subtle derangements of embryonic or fetal development. A concern is that any agent or combination of agents and maternal condition(s) may be teratogenic, a risk that is increased in the transplant population. The goal of immunosuppression is to ensure graft and patient survival by preventing acute rejection. Combinations of agents allow for synergistic effects while minimising drug toxicities. No specific combination has been deemed optimal and the effects of more recently available combinations require further study. Although there are known theoretical risks to mother and fetus, successful pregnancies are now the rule in transplant recipients. This is without an apparent increase in the type or incidence of malformations in the newborns, and usually with no evidence of graft dysfunction and/or irreversible deterioration either related to prepregnancy graft problems or unpredictable gestational factors. For immunosuppression, what is best for the mother and her survival should ensure the best outcome for the fetus and, although no specific malformation pattern has been reported to date, there are some interesting trends worthy of continued analyses. A balance of good maternal and graft outcome with the lowest risk of fetal toxicity must be the goal of management.

Abstract
BACKGROUND Data on the safety of azathioprine and mercaptopurine during pregnancy are very sparse. AIM To examine the risk of adverse birth outcomes in women who took up prescriptions for azathioprine or mercaptopurine during pregnancy. METHODS This is a Danish cohort study based on data from a population-based prescription registry, the Danish Birth Registry and the Hospital Discharge Registry. To examine the risk of congenital malformations, we included nine pregnancies exposed 30 days before conception or during the first trimester. To examine perinatal mortality, pre-term birth and low birth weight, we included 10 pregnancies exposed during the entire pregnancy. Eleven different exposed women were included in the study. Outcomes were compared with those of 19 418 pregnancies in which no drugs were prescribed to the mothers. RESULTS Fifty-five per cent of the exposed women had inflammatory bowel disease and 45% other diseases. Adjusted odds ratios for congenital malformations, perinatal mortality, pre-term birth and low birth weight were 6.7 (95% confidence interval, 1.4-32.4), 20.0 (2.5-161.4), 6.6 (1.7-25.9) and 3.8 (0.4-33.3), respectively. CONCLUSIONS Our results suggest that there is an increased risk of congenital malformations, perinatal mortality and pre-term birth in children born to women treated with azathioprine or mercaptopurine during pregnancy. More data are needed to determine whether the associations are causal or occur through confounding.

Abstract
Most women of childbearing age who receive a renal transplant have a return of normal menses and have the ability to become pregnant. Most studies indicate that pregnancy does not adversely affect the transplant kidney's survival as long as renal function is good and serum creatinine is stable before pregnancy. The experience with immunosuppressive drugs has been surprisingly reassuring with no increase in congenital anomalies with cyclosporine, prednisone, and azathioprine. There is little experience with newer drugs. Pregnant transplant recipients need to be monitored for opportunistic infections, which may adversely affect the fetus, including herpes, toxoplasmosis, and CMV. Hypertension, urinary tract infections, and anemia are other common problems in pregnant transplant recipients. Despite a high frequency of premature births, over 80% of pregnancies result in surviving infants.

Abstract
BACKGROUND Pregnancy is feasible in organ-transplanted women, but little is known about possible effects of ciclosporine A on the circulation in the fetus and placenta. AIM To investigate the influence of ciclosporine A (CsA) on the vasoactive effects of serotonin in human umbilical arteries. STUDY DESIGN AND SUBJECTS In vitro perfusion was performed in umbilical cord segments from seven organ-transplanted patients on CsA based immunosuppression and in 17 cords from uncomplicated pregnancies. Serotonin was administered in stepwise increasing concentrations from 10(-10) to 10(-5) M. In preparations from normal pregnancies, serotonin 10(-7) M, was administered before and 30 min after the start of a continuous CsA infusion (1.0 mg/l). The influence of CsA 0.1 or 1.0 mg/l on the basal, unstimulated perfusion pressure was investigated in separate experiments. OUTCOME MEASURES Changes in perfusion pressure due to constrictory or dilatatory responses. RESULTS In all preparations from the organ-transplanted patients, serotonin induced a constrictory response that was non-significantly lower than that observed in the control group. The frequency of a dilatatory response preceding the vasoconstriction was 3/7 and 12/17 (non-significant) in the CsA-treated and control groups, respectively. In the experiments with CsA administration, a non-significant increase in the constrictory serotonin response was observed as compared to the control experiments. CsA did not alter the basal, unstimulated perfusion pressure. CONCLUSION CsA did not have any significant influence on the vasoactive effect of serotonin in human umbilical arteries perfused in vitro.

Abstract
Modern medicine is increasingly aware of the significance of patient autonomy in making treatment choices. This would seem to be particularly important where the therapy requested was "voluntary" as in fertility treatment or cosmetic surgery. However, the Hippocratic doctrine "Primum non nocere", seems especially relevant where the treatment sought may have a low chance of a successful outcome or even be life-threatening. Mrs A's case demonstrates the difficulty faced by the physician who wants to maximise her patient's autonomy, but "Above all, do no harm".

Abstract
Childbearing is important to women with renal disease, but pregnancy has generally been regarded as very high risk in these women. In this review, an attempt is made to clarify the nature and severity of those risks in the settings of chronic renal insufficiency and end-stage renal disease, including dialysis patients and transplant recipients. Hypertension is the most common life-threatening problem in all three groups. A wide range of antihypertensive medications have been used, with angiotensin-converting enzyme inhibitors the only drugs absolutely contraindicated because of their association with neonatal anuria, pulmonary hypoplasia, and neonatal death. Women with serum creatinine levels of 1.4 mg/dL or greater are at risk for accelerated loss of renal function compared with women who don't become pregnant. Transplant recipients have a risk for loss of renal function similar to controls as long as renal function is well preserved. The frequency of conception is decreased in women with renal insufficiency and markedly decreased in dialysis patients (0.5% per year). Return of fertility is the rule in transplant recipients. Exposure to immunosuppressive drugs, including prednisone, azathioprine, cyclosporine, and tacrolimus, has not been associated with an increase in congenital anomalies. These drugs, particularly cyclosporine, have been associated with small-for-gestational-age babies. Transplant recipients are at risk for infections that have implications for the fetus, including cytomegalovirus, herpes simplex, and toxoplasmosis. All groups have an increased risk for prematurity and intrauterine growth restriction. The percentage of pregnancies resulting in surviving infants in women with renal insufficiency and transplant recipients ranges from 70% to 100%. For women who conceive after starting dialysis, the likelihood of a surviving infant is approximately 50%.

Abstract
Successful pregnancy outcomes are possible after solid organ transplantation. While there are risks to mother and fetus, there has not been an increased incidence of malformations noted in the newborn of the transplant recipient. It is essential that there is closely coordinated care that involves the transplant team and an obstetrician in order to obtain a favourable outcome. Current data from the literature, as well as from reports from the National Transplantation Pregnancy Registry (NTPR), support the concept that immunosuppression be maintained at appropriate levels during pregnancy. At present, most immunosuppressive maintenance regimens include combination therapy, usually cyclosporin or tacrolimus based. Most female transplant recipients will be receiving maintenance therapy prior to and during pregnancy. For some agents, including monoclonal antibodies and mycophenolate mofetil, there is either no animal reproductive information or there are concerns about reproductive safety. The optimal (lowest risk) transplant recipient can be defined by pre-conception criteria which include good transplant graft function, no evidence of rejection, minimum 1 to 2 years post-transplant and no or well controlled hypertension. For these women pregnancy generally proceeds without significant adverse effects on mother and child. It is of note that the epidemiological data available to date on azathioprine-based regimens are favourable in the setting of a category D agent (i.e. one that can cause fetal harm). Thus, there is still much to learn regarding potential toxicities of immunosuppressive agents. The effect of improved immunosuppressive regimens which use newer or more potent (and potentially more toxic) agents will require further study.

Abstract
Retrospective analyses of pregnancies in female renal transplant recipients including case reports, center reports, and questionnaire surveys have, for the most part, reached similar conclusions. In the presence of adequate, stable graft function, these high-risk pregnancies are generally well tolerated, but the majority of the liveborn outcomes are premature and many of the newborns are low birthweight. Obstetrical complications such as preeclampsia and cesarean section occur in a significant proportion of cases. With improvements in methods of data acquisition and computer technology, the aim for the future must be enhanced communication between transplant centers on a prospective basis, perhaps comparing cases with patient profiles derived from analyzed databases such as the National Transplantation Pregnancy Registry (NTPR). Continued efforts to identify prepregnancy risk factors as well as optimal antenatal management strategies will help to further improve pregnancy outcomes in this population. Discussed in this review are reports from the literature as well as current data from the NTPR focusing on the medical management of pregnancy in the renal transplant recipient.

Abstract
Pregnancy is associated with specific immunological tolerance to fetal antigens suggesting that immunoregulatory processes during pregnancy can induce specific immunological unresponsiveness. We report a case of a female renal transplant recipient who stopped immunosuppressive therapy during first pregnancy. Despite histologically proven acute renal allograft rejection during the early course of transplantation, no immunological response was observed for 9 years after withdrawal of immunosuppression. Two further pregnancies within that time period did not evoke any renal complications, but were complicated by premature rupture of the amnion and by the development of preeclampsia. To our knowledge, there are no reports of such a long-term specific unresponsiveness to a renal allograft without immunosuppressive therapy. Natural and active immunoregulatory mechanism can be related for the development of specific immune tolerance to renal allograft in this case.

Abstract
Successful renal transplantation enables previously infertile females to conceive and carry a pregnancy. Much of the reported data on posttransplantation pregnancy accrued before the advent of cyclosporine, when steroids and azathioprine were the mainstays of maintenance immunosuppression. One factor affecting pregnancy outcome in kidney recipients is the length of time from transplantation to conception or transplant interval. It has been recommended that patients wait at least 2 years posttransplantation to conceive, as transplant intervals of shorter duration have had less favorable outcomes. Some have suggested that extended transplant intervals (> 5 years) paradoxically result in adverse outcomes. We have extracted data on cyclosporine-treated recipients with transplant intervals longer than 5 years from the National Transplantation Pregnancy Registry, and report 17 pregnancies from 15 recipients (transplant interval, 5.9 +/- 0.9 years). There were 13 live births (76.5%) and four spontaneous abortions (23.5%). The mean gestational age was 37.7 +/- 2.04 weeks and mean birth weight was 2,753 +/- 679 g. Prematurity occurred in 30.8%, low birth weight in 15.4%, very low birth weight in 7.7%, and neonatal complications in 15.4%. There were no maternal or neonatal deaths. The mean serum creatinine before pregnancy was 1.31 mg/dL, and there was no significant change during or after pregnancy. There were no rejections during or up to 3 months postpartum. Graft survival at 2 years was 100%. We conclude that most pregnancy outcomes in cyclosporine-treated recipients with transplant intervals greater than 5 years are favorable for the newborn, recipient, and graft.

Abstract
In 1992 we published a case-controlled study of posttransplant follow-up in 36 renal allograft recipients (Am J Kidney Dis 19:167-172, 1992). Eighteen of these patients became pregnant and comprise the index group; the 18 patients who did not become pregnant were considered controls. By the end of the follow-up period, plasma creatinine in the index group and controls had increased by 19% and 8%, respectively. Graft loss or chronic rejection occurred in one patient in the index group and in two in the control group. As there were no significant differences between the two groups, we concluded that pregnancy was unlikely to have a major effect on long-term graft function and/or survival. Subsequently, a case control study of Finnish women demonstrated graft survival favoring women who never conceived versus those who did (69% v 100%, respectively; P < 0.005) and thus prompted us to extend our posttransplant follow-up by a further 3 years. Data are currently available for 17 index subjects and 17 controls and during the entire follow-up period, graft losses have occurred in one index subject and in four controls. Plasma creatinine at the end of the follow-up period (1.40 +/- 0.52 mg/dL and 1.54 +/- 0.95 mg/dL, respectively) had increased from 3 years earlier by 11% and 7%, respectively, increments across time that were not significant. Although the increase in plasma creatinine was greater in the index subjects compared with the controls, there were no significant differences between the two groups. While our data do not exclude a minor deleterious effect of pregnancy on long-term graft function, we believe that female allograft recipients can be reassured that pregnancy is unlikely to substantially alter long-term graft function.

Abstract
Between January 1968 and December 1992, 136 kidney transplants were performed in the University Hospital of Ribeirão Preto, with women of childbearing age (14 to 40 years) as receptors. From this population, 19 patients became pregnant at least once after transplantation, and 2 were transplanted inadvertently during the first trimester of their pregnancies. There was a total of 25 pregnancies and 27 offspring. The mean age at the time of conception was 28.6 years (23 to 41 years), with a mean interval of 3.5 years from transplant to conception (< 1 to 16 years). All patients continued their immunosuppressive regimens during the entire pregnancy, but only 5 of 25 were taking cyclosporine. There were two miscarriages (8%) and two therapeutic abortions (8%); of those that passed the 20th week of pregnancy, the mean gestation time at delivery was 35 weeks (range, 28 to 38 weeks) with an incidence of prematurity (gestation < 37 weeks) of 67%, and their offspring weighed from 670 to 3,100 g (mean, 2,236 g), presenting a very high incidence of low birthweight (64%). There was one stillborn and one neonatal death. The most common complications that occurred during pregnancy were infections (especially urinary tract and vaginal mycotic infections) followed by hypertension. The obstetric complications were distributed as follows: premature rupture of membranes in 27%, fetal distress in 24%, preterm labor in 24%, and oligohydramnios in 10%. Lower segment cesarean section was necessary in 16 of 21 cases (76%), and all were for obstetric reasons. One patient died during the puerperium because of sepsis.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Reflux nephropathy is one of the renal diseases encountered most frequently in women of childbearing age. Patients with severe bilateral atrophy are the most likely to develop proteinuria, hypertension, focal glomerular sclerosis and progressive chronic renal failure, and those with persistent vesicoureteral reflux are the most likely to suffer recurrent pyelonephritic episodes. Often the disease is clinically latent and first manifests itself in pregnancy, mainly by urinary tract infection but also by proteinuria, hypertension, pre-eclampsia or renal failure. Pregnancy is most often successful and uneventful whenever renal function is normal or near normal and hypertension is absent at conception. Urinary tract infection accounts for frequent morbidity but rarely results in fetal mortality. By contrast, when renal function is significantly impaired, that is in patients whose plasma creatinine concentration is in excess of 0.20-0.22 mmol l-1 at conception, especially when hypertension is also present, there is clearly a high risk of fetal growth retardation or intrauterine death. Moreover, there is a striking risk of rapid worsening of renal function and hypertension, with accelerated progression towards end-stage renal failure. Thus, women with reflux nephropathy should attempt to conceive before the plasma creatinine concentration has reached 0.20 mmol l-1, and patients with values higher than these should be clearly advised of the high risk for both the pregnancy and the progression of the disease.

Abstract
Improvements in reproductive function invariably follow renal transplantation. The possibility of conception in women of childbearing age emphasizes the need for compassionate and comprehensive counselling. Couples who want a child should be encouraged to discuss all the implications. Therapeutic abortion is undertaken in 20% of conceptions and the spontaneous abortion rate is about 14%, the same as for the normal population. Of the conceptions that continue beyond the first trimester, 93% end successfully. In most women, renal function is augmented during pregnancy, but permanent impairment occurs in 15% of pregnancies. In others there may be transient deterioration in late pregnancy (with or without proteinuria). There is a 30% chance of developing hypertension, pre-eclampsia or both. Preterm delivery occurs in 45-60%, and intrauterine growth retardation in at least 20% of pregnancies. Despite its pelvic location, the transplanted kidney rarely produces dystocia and is not injured during vaginal delivery. Caesarean section should be reserved for obstetric reasons only. Neonatal complications include respiratory distress syndrome, leucopenia, thrombocytopenia, adrenocortical insufficiency and infection. No predominant or frequent developmental abnormalities have been described and data on infancy and childhood are encouraging. Future clinical and laboratory research needs to focus on improving prepregnancy assessment criteria, better understanding of the mechanisms of gestational renal dysfunction, proteinuria and the rare, but devastating, accelerated rejection, assessing the side-effects and implications of immunosuppression in pregnancy and learning more about the remote effects of pregnancy on both renal prognosis and the offspring.

Abstract
In human pregnancy, effective renal plasma flow and glomerular filtration rate increase to levels 50-80% above non-pregnant values. The increments occur shortly after conception, persist throughout the second trimester and reduce slightly in late pregnancy. The hyperfiltration of pregnancy does not seem to be a potentially damaging process, as intraglomerular pressure remains unchanged. The increased excretion of glucose and other nutrients, as well as uric acid and protein, is related in part to altered tubular function. Renal physiology is altered so much in pregnancy that non-pregnant norms cannot be used in antenatal care.
