Pregnancy after transplantation

Immunosuppressant Medications in Pregnancy

Pregnant patients are often on immunosuppressant medications, most commonly to manage transplantation or autoimmune disorders. Most immunosuppressant agents, including tacrolimus, corticosteroids, azathioprine, and calcineurin inhibitors, are safe during pregnancy and lactation. However, mycophenolic acid is associated with higher risks of birth defects and should be avoided in pregnancy. Tacrolimus, the commonly used drug in transplantation medicine and autoimmune disorders, requires monitoring of serum levels for dose adjustment, particularly during pregnancy. Although no pregnancy-specific therapeutic range exists, the general target range is 5-15 ng/mL, and pregnant patients may require higher doses to achieve therapeutic levels. Adherence to prescribed immunosuppressive regimens is crucial to prevent graft rejection and autoimmune disorder flare-ups. This review aims to provide essential information about the use of immunosuppressant medications in pregnant individuals. With a rising number of pregnant patients undergoing organ transplantations or having autoimmune disorders, it is important to understand the implications of the use of these medications during pregnancy.

Successful full-term pregnancy after preterm event in a liver transplant patient: a case report

BACKGROUND

Pregnancy after liver transplantation poses a significant challenge to both the patient and the transplant team.

CASE PRESENTATION

We present the case of a 19-year-old European patient who underwent liver transplantation 5 years previously owing to autoimmune hepatitis. Poor compliance with immunosuppressive therapy and missed follow-up visits during the patient's first pregnancy likely contributed to her liver function deterioration, hospitalization, and failed pregnancy. Owing to the patient's complex medical history, combined immunosuppressive treatment, and risks to the fetus, her second pregnancy was high risk. However, close outpatient monitoring and adherence to treatment led to a successful, uneventful, full-term pregnancy and healthy delivery.

CONCLUSION

Liver transplant recipients who desire to become pregnant require careful planning and management to ensure optimal outcomes for both the mother and the fetus. A personalized strategy is necessary to balance the potential benefits of childbirth with the risks involved in pregnancy after liver transplantation.

Fetal endothelial colony-forming cell impairment after maternal kidney transplantation

BACKGROUND

Successful pregnancies are nowadays possible after kidney transplantation but are associated with a higher incidence of maternal and fetal complications. Immunosuppressive therapy causes cardiovascular side effects but must be maintained during pregnancy. Little is known about the consequences of maternal kidney transplantation on offspring's endothelial health. Endothelial colony forming cells (ECFCs) represent a highly proliferative subtype of endothelial progenitor cells and are crucial for vascular homeostasis, repair and neovascularization. Therefore, we investigated whether maternal kidney transplantation affects fetal ECFCs' characteristics.

METHODS

ECFCs were isolated from umbilical cord blood of uncomplicated and post-kidney-transplant pregnancies and analyzed for their functional abilities with proliferation, cell migration, centrosome orientation and angiogenesis assays. Further, ECFCs from uncomplicated pregnancies were exposed to either umbilical cord serum from uncomplicated or post-kidney-transplant pregnancies.

RESULTS

Post-kidney-transplant ECFCs showed significantly less proliferation, less migration and less angiogenesis compared to control ECFCs. The presence of post-kidney-transplant umbilical cord serum led to similar functional aberrations of ECFCs from uncomplicated pregnancies.

CONCLUSIONS

These pilot data demonstrate differences in ECFCs' biological characteristics in offspring of women after kidney transplantation. Further studies are needed to monitor offspring's long-term cardiovascular development and to assess possible causal relationships with immunosuppressants, uremia and maternal cardiovascular alterations.

IMPACT

Pregnancy after kidney transplantation has become more common in the past years but is associated with higher complications for mother and offspring. Little is known of the impact of maternal kidney transplantation and the mandatory immunosuppressive therapy on offspring vascular development. In this study we are the first to address and detect an impairment of endothelial progenitor cell function in offspring of kidney-transplanted mothers. Serum from post-transplant pregnancies also causes negative effects on ECFCs' function. Clinical studies should focus on long-term monitoring of offspring's cardiovascular health.

Emergent prelabor cesarean delivery in solid organ transplant recipients: associated risk factors and outcomes

BACKGROUND

Pregnancies after solid organ transplant are at a higher risk of antepartum admission and pregnancy complications including cesarean delivery. Emergent prelabor cesarean delivery is associated with increased maternal and neonatal morbidity in other high-risk populations, but its incidence and impact in transplant recipients is not well-understood.

OBJECTIVE

This study aimed to characterize the risk factors and outcomes of emergency prelabor cesarean delivery in kidney and liver transplant recipients.

STUDY DESIGN

This was a retrospective cohort study of all kidney and liver transplant recipients at >20 weeks gestation enrolled in the Transplant Pregnancy Registry International between 1976 and 2019. Participants admitted antepartum who required emergency prelabor cesarean delivery were compared with those admitted antepartum who underwent nonemergent birth. The primary outcomes were severe maternal morbidity and neonatal composite morbidity. Multivariable logistic regression was conducted for neonatal composite morbidity.

RESULTS

Of 1979 births, 181 pregnancies (188 neonates) with antepartum admission were included. 51 pregnancies (53 neonates, 28%) were delivered by emergent prelabor cesarean delivery compared with 130 pregnancies (135 neonates, 72%) admitted antepartum who subsequently did not require emergent delivery. The most common indication for emergent delivery was nonreassuring fetal heart tracing (44 pregnancies /51 emergent deliveries = 86%). Pregnant people who underwent emergent prelabor cesarean delivery were less likely to deliver at a transplant center (37.3% vs 41.5%; P=.04) and had increased rates of chronic hypertension (33.3% vs 16.2%; P=.02). There was no significant difference in severe maternal morbidity (3.9% vs 4.6%; P=.84), though there was an increase in surgical site infection in the emergent prelabor cesarean delivery cohort (3.9% vs 0%; P=.02). Among those with emergent prelabor cesarean delivery, there was a significant increase in neonatal composite morbidity (43.4% vs 19.3%; P<.001) with earlier gestational age at delivery (33.4 vs 34.7 weeks; P=.02), lower birthweight (1899 g vs 2321 g; P<.001), lower birthweight percentile (30.3% vs 40.6%; P=.03), increased neonatal intensive care unit admission (52.8% vs 35.6%; P=.03), and increased neonatal mortality (11.3% vs 1.5%; P=.002). After adjusting for year of conception, race, hypertensive disorders, and fetal malformations, there was a persistent increased risk of neonatal morbidity (adjusted odds ratio, 3.01; 95% confidence interval, 1.50-6.08; P=.002) associated with emergent prelabor cesarean delivery after transplant.

CONCLUSION

Almost one-third of kidney and liver transplant recipients admitted antepartum had an emergency prelabor cesarean delivery, and 63% of this cohort delivered outside of a transplant center. Pregnancies after transplantation should involve multidisciplinary transplant-obstetrics collaboration to ensure optimal antepartum disease management, especially for preexisting hypertension, to prevent and mitigate obstetrical and neonatal morbidity in the setting of emergent cesarean delivery.

Outcomes of Pregnancies in Liver Transplant Recipients: Experience of a Single Center in Turkey

BACKGROUND

Liver transplantation is the ultimate treatment for end-stage liver failure. As organ donation systems improve, more reproductive-age women are expected to undergo liver transplantation. Current studies indicate increased risk of some perinatal and maternal complications; however, the available data is still scarce. Therefore, we aimed to evaluate the maternal and fetal outcomes of pregnancies in liver transplant recipients.

METHODS

We retrospectively evaluated liver transplantations performed between 2011 and 2020 in a tertiary center. Perinatal, maternal, fetal outcomes and transplant status were assessed among pregnancies conceived after liver transplantation.

RESULTS

Among 1137 patients, 82 (7.2%) were reproductive-age females. Ten pregnancies in nine patients were identified after liver transplantation. The mean age of patients was 29.3±6.1 at transplantation, and 32.5±5.4 at conception. The mean interval between conception and transplantation was 30.3±11.7 months. There were eight live births (80%), one miscarriage (10%) and one termination (10%). Three patients delivered<37th gestational week (37.5%). The median gestational age at birth was 38.5 (IQR: 5.21) weeks. The mean birth weight of infants was 2669.3±831 g. Two patients were diagnosed with preeclampsia (25%) and acute graft rejection episode was observed in one patient (10%) during pregnancy.

CONCLUSION

Although the incidence of some perinatal complications, such as hypertensive disorders and preterm delivery, is increased in liver transplant recipients, pregnancy after liver transplantation appears to have favorable outcomes for the mother, fetus and transplant with close monitoring by a multidisciplinary team.

Successful maternal and fetal outcomes in a kidney transplant patient under everolimus throughout pregnancy complicated by pyelonephritis and preeclampsia

Pregnancy in kidney transplant patients has many risks such as worsening renal function and/or proteinuria, allograft rejection, preeclampsia, spontaneous abortion, premature fetal delivery, and low fetal birthweight. We report a case of a 35-year-old patient with a history of kidney transplant, who received everolimus throughout pregnancy and experienced a successful cesarean delivery with positive maternal and fetal outcomes. Information regarding everolimus use in pregnancy is limited. However, data from animal studies suggest that everolimus may cause fetal harm when administered during pregnancy. In our case, everolimus did not affect the pregnancy of this patient; cesarean delivery was performed without complications. Owing to the increased risks and monitoring required during pregnancy in patients with a previous kidney transplant and limited information regarding the use of antirejection agents during pregnancy, care throughout pregnancy should involve a multidisciplinary team, including transplant, maternal fetal medicine, and nephrology.

Pregnancy outcomes in female patients exposed to cyclosporin-based versus tacrolimus-based immunosuppressive regimens after liver/kidney transplantation: A systematic review and meta-analysis

WHAT IS KNOWN AND OBJECTIVE

Pregnancy after transplantation is a challenge owing to the high risk of adverse maternal and foetal outcomes, and immunosuppressants may further impact these outcomes. There are no head-to-head randomized controlled trials comparing influences of cyclosporin and tacrolimus on pregnancy outcomes. Thus, we systematically reviewed and meta-analysed observational studies assessing the comparative influences of these two drugs on pregnancy outcomes in liver/kidney transplant recipients.

METHODS

Relevant studies comparing pregnancy outcomes with tacrolimus and cyclosporin head-to-head were searched in PubMed, EMBASE and Web of Science (from 1 January 2000 to 20 March 2020). The weighted mean difference and odds ratio (OR) were calculated to compare continuous and dichotomous variables, respectively, with 95% confidence intervals (CIs). Publication bias was estimated using funnel plots. The study quality was assessed according to the modified Newcastle-Ottawa scale.

RESULTS AND DISCUSSION

Overall, 10 observational studies of low quality, including a total of 1080 post-liver or kidney transplant pregnancies, were identified. Tacrolimus-treated recipients experienced a lower risk of gestational hypertension (28.0%; OR: 1.74; 95% CI: 1.27-2.39; p < 0.01). Cyclosporin-treated recipients showed a lower incidence of caesarean section (40.3%; OR: 0.62; 95% CI: 0.46-0.82; p < 0.01). Additionally, cyclosporin performed better in terms of the live birth rate (78.0%; OR: 1.38; 95% CI: 1.02-1.88; p = 0.04). No significant differences in the incidences of pre-eclampsia, gestational diabetes, preterm delivery and birth weight were observed.

WHAT IS NEW AND CONCLUSION

Tacrolimus performed better in patients with gestational hypertension, while cyclosporin was associated with a lower incidence of caesarean section and a higher incidence of live birth. The findings are based on relatively low-quality evidence, but may provide a reference for clinicians in their clinical monitoring and obstetric care for post-transplant pregnancies.

Sexual and reproductive health in cystic fibrosis

PURPOSE OF REVIEW

With improving life expectancy and quality of life, sexual and reproductive health (SRH) has become an increasingly important aspect of patient-centered cystic fibrosis care. This review aims to describe advances in cystic fibrosis-related SRH and highlight optimal practices.

RECENT FINDINGS

Recent publications suggest that people with cystic fibrosis follow a similar trajectory of sexual development and activity as their noncystic fibrosis peers, although contraception use is lower. Although fertility is reduced in patients with cystic fibrosis, improved survival and assisted reproductive technologies have led to an increasing pursuit and incidence of pregnancy. Cystic fibrosis transmembrane regulator modulators that correct the underlying cystic fibrosis defect might improve fertility and thus far appear safe in pregnancy, though data are limited.Despite medical knowledge of SRH in cystic fibrosis, patients continue to report they lack sufficient education about these aspects of their healthcare, and cystic fibrosis multidisciplinary teams are ill prepared to counsel their patients.

SUMMARY

Understanding of the effects of cystic fibrosis on SRH continues to improve, although many questions remain regarding optimal care from the choice of contraception to the safety of cystic fibrosis-specific medications in pregnancy. Further development of cystic fibrosis-informed interdisciplinary specialist networks and a wider framework of practice would both enhance health outcomes and better support patients.

Risk stratification and management of women with cardiomyopathy/heart failure planning pregnancy or presenting during/after pregnancy: a position statement from the Heart Failure Association of the European Society of Cardiology Study Group on Peripartum Cardiomyopathy

This position paper focusses on the pathophysiology, diagnosis and management of women diagnosed with a cardiomyopathy, or at risk of heart failure (HF), who are planning to conceive or present with (de novo or previously unknown) HF during or after pregnancy. This includes the heterogeneous group of heart muscle diseases such as hypertrophic, dilated, arrhythmogenic right ventricular and non-classified cardiomyopathies, left ventricular non-compaction, peripartum cardiomyopathy, Takotsubo syndrome, adult congenital heart disease with HF, and patients with right HF. Also, patients with a history of chemo-/radiotherapy for cancer or haematological malignancies need specific pre-, during and post-pregnancy assessment and counselling. We summarize the current knowledge about pathophysiological mechanisms, including gene mutations, clinical presentation, diagnosis, and medical and device management, as well as risk stratification. Women with a known diagnosis of a cardiomyopathy will often require continuation of drug therapy, which has the potential to exert negative effects on the foetus. This position paper assists in balancing benefits and detrimental effects.

Paternity in male kidney transplant recipients: a French national survey, the PATeRNAL study

Background

There is concern about the impact of immunosuppressive agents taken by male kidney transplant (KT) recipients on the risk of foetal malformations. The aim of our survey was to estimate the paternity rate and the outcomes of pregnancies fathered by kidney transplanted males.

Methods

This survey analysed 1332 male KT recipients older than 18 years, followed in 13 centres in France. A self-reported questionnaire was used to collect data on the patients, treatments at the time of conception and the pregnancy outcomes.

Results

The study included data on 349 children from 404 pregnancies fathered by 232 male KT recipients. The paternity rate was 17% (95% CI [15–20]). There were 37 (9%, 95% CI [7–12]) spontaneous abortions, 12 (3%, 95% CI [2–5]) therapeutic abortions, 2 (0.5%, 95% CI [0.1–1]) still births, and 13 (4%, 95% CI [2–6]) malformations reported. Compared to the general population, there was no difference in the proportion of congenital malformations nor unwanted outcomes whether the father was exposed or not to immunosuppressive agents.

Conclusions

This survey does not provide any warning signal that pregnancies fathered by male patients exposed to immunosuppressive agents, notably the debated MMF/MPA, have more complications than pregnancies in the general population.

Pregnancy Following Heart Transplantation: A Single Centre Case Series and Review of the Literature

BACKGROUND

Maternal and fetal outcomes of pregnancy amongst cardiac transplant recipients are limited in the current literature.

METHODS

We describe five pregnancies in three cardiac transplant recipients managed between a tertiary centre for obstetric medicine and an associated state-wide transplant centre between 2014-2018, and provide a narrative review of the literature.

RESULTS

Pre-conception counselling was undertaken. There were no recent rejection episodes and all women demonstrated good baseline cardiac function. Median maternal age was 27 years (range 23-38 yrs.). Median time from transplantation to pregnancy was 5 years (range 2-14 yrs.). All women were managed with modified immunosuppressant regimens and multidisciplinary care. Cardiac function, tacrolimus levels and renal function were closely monitored with frequent monitoring for common complications of pregnancy. There were no maternal or fetal deaths. There was no evidence of graft rejection and no deterioration in cardiac function. Tacrolimus doses were increased to maintain therapeutic targets. Gestational diabetes occurred in three women and cholestasis of pregnancy occurred in one. Each infant was delivered by vaginal delivery. One mother had postpartum haemorrhage in both pregnancies. Pre-eclampsia did not occur. Median gestation at delivery was 37 weeks (range 35⁺⁴-40⁺⁵ days) with two preterm deliveries. One (1) infant was born with low birth weight. One (1) infant had jaundice requiring phototherapy. All infants were breastfed.

CONCLUSION

Pregnancy in transplant recipients confers risk to the mother and fetus. Pre-conception counselling, immunosuppressant tailoring and regular monitoring are paramount to avoid rejection and possible teratogenic complications. Favourable pregnancy outcomes are achievable with specialist multidisciplinary care.

Pregnancy outcomes in women with liver transplants: systematic review and meta-analysis

BACKGROUND

Despite increasing reports of pregnancy in liver transplant recipients, questions remain about the impact of transplantation in pregnancy.

METHODS

This systematic review was performed according to PRISMA guidelines and eligible studies were identified through a search of PubMed, Scopus and Cochrane CENTRAL databases up to 26th December 2019 for studies reporting pregnancy with liver transplant. A meta-analysis was conducted with the use of random-effects modelling and prospectively registered with the PROSPERO database.

RESULTS

Of 1239 unique studies, 28 met inclusion criteria, representing 1496 pregnancies in 1073 liver transplant recipients. The live-birth rate was 85.6% (CI95%: 80.5%-90.7%). The rate of other pregnancy outcomes was as follows: induced abortions (5.7%), miscarriages (7.8%) and stillbirths (3.3%). Pooled rates of obstetric complications were hypertension (18.2%), pre-eclampsia (12.8%) and gestational diabetes (7.0%). Pooled rates of delivery outcomes for caesarean section (C-section) and pre-term birth were 42.2% and 27.8%, respectively.

CONCLUSION

In conclusion, live birth outcomes are good among liver transplant recipients and this favourable trend is consistent at an international level. However, special attention should be given to obstetric complications such as hypertension, pre-eclampsia, and preterm delivery. The high incidence of these complications supports the high-risk classification of post-liver transplant pregnancies and it is necessary for a multidisciplinary team to be involved in the monitoring and counselling of liver transplant recipients both before and during pregnancy. Whilst majority data originate from institutions from high-income countries, data from low-middle income countries (LMIC) are needed owing to rising rates of liver transplantation in LMIC.

Pregnancy after lung and heart-lung transplantation: a French multicentre retrospective study of 39 pregnancies

Pregnancy after lung and heart–lung transplantation remains rare. This French study deals with change in lung function after a pregnancy and the maternal and newborn outcomes.

We retrospectively included 39 pregnancies in 35 women aged >20 years. Data on patients, course of pregnancies and newborns were collected from nine transplantation centres.

Mean age at time of pregnancy was 28 years. Cystic fibrosis affected 71% of patients. Mean±sd time between transplantation and pregnancy was 63±44 months. 26 births occurred (67%) with a mean term of 36 weeks of amenorrhoea and a mean birthweight of 2409 g. Prematurity was observed in 11 cases (43%). Forced expiratory volume in 1 s was 83.9% of predicted before pregnancy and 77.3% of predicted 1 year after the end of pregnancy (p=0.04). 10 patients developed chronic lung allograft dysfunction after delivery. Nine patients died at a mean±sd time after transplantation of 8.2±7 years and a mean±sd time after pregnancy of 4.6±6.5 years.

These data show that pregnancy remains feasible in lung and heart–lung transplant recipients, with more frequent maternal and newborn complications than in the general population. Survival in this cohort appears to be similar to the global survival observed in lung transplant recipients. Planned pregnancy and multidisciplinary follow-up are crucial.

Pregnancy in lung and heart–lung recipients remains rare but possible. There is a significant decrease in FEV₁ pre- and post-pregnancy, but overall outcomes are reassuring. Specialised, multidisciplinary follow-up is necessary.http://bit.ly/31iXxov

Outcomes of Pregnancy in Recipients of Liver Transplants

BACKGROUND & AIMS

Despite increasing reports of pregnancy in women who received liver transplants, it is not clear how transplantation and immunosuppression affect pregnancy. We collected data from liver transplant recipients who became pregnant on immunosuppression regimens, pregnancy management, graft morbidity, and outcomes of mothers and neonates.

METHODS

We searched the liver transplant database in Birmingham, United Kingdom, for women who reported pregnancy after liver transplantation from August 1986 through May 2016. We collected information on morbidities and outcomes of 139 pregnancies in 83 women (median age at conception, 27 y; range, 15-46 y). Fisher exact tests were used to compare categoric variables and Mann-Whitney U and Kruskal-Wallis tests were used to compare continuous variables. The primary outcome was the live birth rate in the entire cohort. Additional outcomes analyzed included differences in immunotherapy regimens, and outcomes associated with exposure to cyclosporine and tacrolimus, time to transplantation (<12 vs >12 mo), and time period of pregnancy (1986-2000 vs 2001-2016).

RESULTS

Of the pregnancies, 69% resulted in live births, 19% resulted in miscarriages or still births, and 9% were terminated. A higher proportion of patients who conceived more than 1 year after liver transplantation had live births than of women who conceived before this time (98% vs 80%; P = .006). Tacrolimus exposure was associated with higher risks of premature delivery (P = .045) and caesarian section (P = .031) than cyclosporine exposure. Compared with the period from 1986 to 2000, women who conceived from 2001 to 2016 had a significantly shorter time between transplantation and conception (median, 3 vs 7 y; P = .027), frequent use of tacrolimus vs cyclosporine (84% vs 26%; P = .001), and a higher incidence of cesarean section (44% vs 32%; P = .025).

CONCLUSIONS

Almost 70% of women who conceive after liver transplantation have live births, although this rate is lower than that of women in the overall population. These cases require involvement of hepatologists and obstetricians.

A New Life: Motherhood After Heart Transplantation. A Single-center Experience and Review of Literature

BACKGROUND

Pregnancy after heart transplantation (HTx) may expose the recipient to hemodynamic and immunologic risks and the newborn to toxic effects of immunosuppressive therapy. Adequate preconception counseling is crucial to identify optimal timing and to modify immunosuppressive therapy to minimize risks for both the mother and the fetus.

METHODS

We describe our experience with 12 pregnancies occurred in 11 women who had undergone HTx at our center.

RESULTS

Pregnancies ran without severe complications or rejections, and none of the babies have shown major defects at birth. However, as reported in the literature, weight at birth rated in lower range in most of the newborns, probably due to in utero cyclosporine exposure. Up to now, none of the babies showed clinical signs of heart disease, although more than half of the mothers had an inherited or familial cardiomyopathy.

CONCLUSIONS

Despite potential mother and fetal complications, successful pregnancy and delivery are possible after HTx, provided that optimum timing, close monitoring, and therapy adjustments are guaranteed. Becoming a mother appears to be an important achievement for young women after HTx, even when there is a risk to transmit an inheritable heart disease.

The Impact of Immunosuppressive Drugs on Human Placental Explants

The use of immunosuppressive drugs guarantees the vitality of the graft and allows gestation in spite of intercurrences such as prematurity and intrauterine growth restriction. However, little is known about the direct effects of immunosuppressive drugs on placental cells. We investigated the effects of immunosuppressive drugs in the chorionic villous explants from human term placentas of healthy gestations. Human placental explants from term gestations (37-39 week gestational age, n = 12) were exposed to cyclosporine A (CSA, 0, 62.5, 125, 1250 ng/mL) or azathioprine (AZA, 0, 5, 10, 100 ng/mL) separately or, in combination for up to 48 hours. 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assays showed a significant decrease in the explant metabolic activity between AZA and the control group (24 hours, 100 ng/mL, 48 hours, all concentrations, P < .005). Cyclosporin A (CsA) reduced cell activity when associated with AZA (48 hours, P < .005). Fibrinoid deposits increased in AZA-treated explants alone (5 ng/mL, 48 hours; 10 ng/mL, 24-48 hours; P < .005) or when associated with CsA (10 AZA/125 CsA, P < .05), whereas in CsA treatment alone, there was an augment in syncytial knots (24-48 hours, P < .005). The sFLT1 gene (24 hours, P < .05) and protein ( P < .005) expression increased in AZA and CsA-treatments separately or in combination ( P < .05). Placental growth factor increased in AZA (24 hours, 10 ng/mL) and CsA (125 ng/mL; P < .05). In conclusion, our data indicate that AZA primarily acts on the villous metabolism, perturbing placental homeostasis. Since these drugs may alter the balance of angiogenic factors in its selection for clinical application, their impact on the behavior of placental villous should be considered.

Successful remission of ulcerative colitis flare-up during pregnancy with adsorptive granulomonocytapheresis plus tacrolimus

Ulcerative colitis (UC) is 1 of the 2 major phenotypes of chronic inflammatory bowel disease (IBD), which afflicts millions of individuals throughout the world with debilitating symptoms that impair function and quality of life. Further, IBD often affects women during childbearing age. Indeed, UC activity frequently increases during pregnancy, and the medications used to induce remission may adversely affect the health of the mother and the unborn child. We report successful induction of a remission in a UC case who experienced a flare-up in the first trimester of pregnancy. Upon relapse, she was treated with steroids and adsorptive granulomonocytapheresis (GMA) with the Adacolumn plus tacrolimus. This combination therapy induced a stable remission that was maintained during her entire pregnancy. She gave birth to a healthy child at 36 weeks of pregnancy with no maternal or fetal complications. Our experience indicates that GMA, as a non-drug therapeutic intervention with a favorable safety profile, plus tacrolimus might be a relevant treatment option for patients with active IBD during pregnancy. A future study of a large cohort of pregnant patients should strengthen our findings.

Anesthetic Considerations for the Parturient After Solid Organ Transplantation

Over the past 40 years, the success of organ transplantation has increased such that female solid organ transplant recipients are able to conceive and carry pregnancies successfully to term. Anesthesiologists are faced with the challenge of providing anesthesia care to these high-risk obstetric patients in the peripartum period. Anesthetic considerations include the effects of the physiologic changes of pregnancy on the transplanted organ, graft function in the peripartum period, and the maternal side effects and drug interactions of immunosuppressive agents. These women are at an increased risk of comorbidities and obstetric complications. Anesthetic management should consider the important task of protecting graft function. Optimal care of a woman with a transplanted solid organ involves management by a multidisciplinary team. In this focused review article, we review the anesthetic management of pregnant patients with solid organ transplants of the kidney, liver, heart, or lung.

Pregnancy in chronic kidney disease and kidney transplantation

Chronic kidney disease (CKD) affects up to 6% of women of childbearing age in high income countries, and is estimated to affect 3% of pregnant women. Advanced renal dysfunction, proteinuria, hypertension, and poorly controlled underlying primary renal disease are all significant risks for adverse maternal, fetal, and renal outcomes. In order to achieve the best outcomes, it is therefore of paramount importance that these pregnancies are planned, where possible, to allow the opportunity to counsel women and their partners in advance and to optimize these risks. These pregnancies should be deemed high risk and they require close antenatal monitoring from an expert multidisciplinary team. We discuss the effect of pregnancy on CKD, and also current guidelines and literature with specific reference to transplantation, autoimmune disease, and medication use in pregnancy. We also discuss the benefits of prepregnancy counseling and give practical recommendations to advise pregnant women with renal disease.

A complicated multisystem flare of systemic lupus erythematosus during pregnancy

We report a case of systemic lupus erythematosus (SLE) in a young woman who became pregnant amid a severe flare. She continued to have active disease in the face of aggressive treatments complicated by several side effects of immunosuppressive drugs including recurrent sepsis and gestational diabetes. Her fetus was at risk for congenital heart block during the second and third trimesters. Despite an extremely guarded prognosis, she delivered a healthy baby girl. This case highlights the complexities of SLE management during pregnancy. We discuss the therapeutic options available in pregnancy, and highlight the importance of cross-specialty multidisciplinary care in these women.

Managing pregnancy in chronic kidney disease: improving outcomes for mother and baby

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

Anesthesia management for cesarean section 10 years after heart transplantation: a case report

Introduction

Pregnancy after organ transplantation is becoming increasingly common. However, reports of the anesthesia for such patients are rare. Heart transplant recipients are always accompanied with pathophysiological changes and present anesthesiologists with challenge.

Case description

We reported a case of anesthesia management of gravida undergoing cesarean section 10 years after cardiac transplantation. We used two points spinal and epidural anesthesia, combined with phenylephrine throughout the surgery. The course was absolutely successful and both mother and baby got good results.

Discussion and evaluation

Physiology of heart transplant recipients and key points of anesthesia management were discussed.

Conclusions

Spinal anesthesia can be performed in heart transplant recipients, however, we have to think twice before anesthesia for this kind of patients.

Pregnancy outcomes following maternal kidney transplantation: a national cohort study

INTRODUCTION

Internal design flaws in previous reports of pregnancies following kidney transplantation have been outlined, and the need for a validation has been stated. The aim of this study was to collect information about obstetrical and neonatal outcomes in all Norwegian pregnancies following maternal kidney transplantation, and to compare these data with the general Norwegian population.

MATERIAL AND METHODS

A retrospective cohort study based on 1 272 000 deliveries in Norway between 1969 and 2013. All data were collected from medical records. From the source population, we compared 119 first deliveries in kidney transplanted women with 238 first deliveries in nontransplanted women. An explanatory strategy was used in the analysis.

RESULTS

The risk of preeclampsia was significantly increased in kidney-transplanted women compared with nontransplanted women (adjusted incidence rate ratio: 6.06, 95% confidence interval 3.18-11.55). Additionally, preeclampsia in kidney-transplanted women was early onset (diagnosed <34 gestational weeks) in half of the cases. There were also persistent risks of cesarean delivery (adjusted incidence rate ratio 4.14, 95% confidence interval 2.56-6.66), preterm delivery (adjusted incidence rate ratio 4.45, 95% confidence interval 2.13-9.30) and a birthweight below the 10th centile (22.7% vs. 9.7%) in the kidney-transplanted group. A high proportion (63%) of the kidney-transplanted women with chronic hypertension developed preeclampsia.

CONCLUSIONS

Using consistent diagnostic criteria, this study shows high rates of maternal and neonatal complications in pregnancies following kidney transplantation. In particular, we reveal a high rate of early-onset preeclampsia requiring operative preterm delivery, conferring long-term risks on both the mother and child.

Pregnancy and autoimmune connective tissue diseases

Autoimmune connective tissue diseases predominantly affect women and often occur during the reproductive years. Thus, specialized issues in pregnancy planning and management are commonly encountered in this patient population. This chapter provides a current overview of pregnancy as a risk factor for onset of autoimmune disease, considerations related to the course of pregnancy in several autoimmune connective tissue diseases, and disease management and medication issues before pregnancy, during pregnancy, and in the postpartum period. A major theme that has emerged across these inflammatory diseases is that active maternal disease during pregnancy is associated with adverse pregnancy outcomes, and that maternal and fetal health can be optimized when conception is planned during times of inactive disease and through maintaining treatment regimens compatible with pregnancy.

Top 10 Things Primary Care Physicians Should Know About Maintenance Immunosuppression for Transplant Recipients

The success of organ transplantation allows many transplant recipients to return to life similar to nontransplant patients. Their need for regular health care, including preventive medicine, has switched the majority of responsibilities for their health care from transplant specialists to primary care physicians. To take care of transplant recipients, it is critical for primary care physicians to be familiar with immunosuppressive medications, their side effects, and common complications in transplant recipients. Ten subjects are reviewed here in order to assist primary care physicians in providing optimal care for transplant recipients.

Surveillance of Immunosuppression During Pregnancy After Heart Transplantation: Case Report

BACKGROUND

Transplantation and immunosuppressive drugs are major limitations to the success of pregnancy. In 1988, the first pregnancy after a heart transplant was reported, which has given female recipients the hope to give birth. During pregnancy, physiologic changes with increased blood volume and hemodilution may influence blood drug level.

CASE REPORT

We reported our experience in monitoring on immunosuppressive drugs for 2 cases. Both of them underwent heart transplantation in 2006 and were 34 and 37 years old at time of pregnancy. For both cases, we frequently monitored the blood level and increased the dosage of immunosuppressive drugs accordingly. Both cases had uneventful pregnancy and delivery to healthy babies at the National Taiwan University Hospital in Taiwan. Their postpartum courses were uneventful as well.

CONCLUSIONS

We advocate adjusting the immunosuppressive dosage according to the blood level before pregnancy.

La grossesse chez les patientes transplantées rénales est à risque de complications maternelles mais surtout fœtales. Le risque de survenue de rejet aigue ou chronique inhérent à la grossesse est faible. L'objectif de notre étude était de rapporter les grossesses survenues chez nos transplantées rénales, leurs aspects évolutifs et une revue de la littérature. L’âge moyen des patientes au moment de la transplantation rénale était de 28,5 ans. Le traitement immunosuppresseur d'entretien a associé une corticothérapie, l'azathioprine et/ou la ciclosporine A. Le délai moyen entre la transplantation rénale et la découverte de la grossesse était de 6,5 ans. L’âge moyen au moment de la conception était de 33,8 ans. Il n'ya pas eu de modifications du traitement immunosuppresseur au cours de la grossesse. La créatininémie moyenne au cours de la grossesse était stable à 104,8 µmol/l avec une créatininémie supérieure à 150 µmol/l dans 2 cas. Les complications maternelles au cours de la grossesse étaient une hypertension artérielle gravidique dans 3 cas, une protéinurie dans 3 cas, une ascension de la créatininémie au 7ème mois dans 2 cas, une cholestase hépatique gravidique dans 2 cas et une hyperuricémie dans 4 cas. Une prématurité était observée dans 3 cas en rapport avec une rupture prématurée des membranes, des contractions utérines sur utérus cicatriciel et des signes de prééclampsie dans le troisième cas. Après l'accouchement, Une hypertension artérielle était observée chez 3 patientes. On n'a pas noté de rejet aigu chez nos patientes. La créatininémie moyenne était de 195,3 µmol/l (74- 553 µmol/l). Le développement statural et psychomoteur était normal pour 9 enfants. La bonne évolution des grossesses chez les patientes transplantées rénales une planification et un suivi régulier.

Obstetric and neonatal outcome of pregnancies fathered by males on immunosuppression after solid organ transplantation

Immunosuppressive drugs may influence spermatogenesis, but little is known about outcome of pregnancies fathered by transplanted males. We estimated risk of adverse outcomes in pregnancies (with data after the first trimester) fathered by males that had undergone organ transplantation and were treated with immunosuppression. A population-based study, linking data from the Norwegian transplant registry and the Medical Birth Registry of Norway during 1967-2009 was designed. All Norwegian men undergoing solid organ transplantation were included. Odds ratios for major malformations, preeclampsia, preterm delivery (<37 weeks) and small-for-gestational-age were obtained using logistic regression. A total of 2463 transplanted males, fathering babies of 4614 deliveries before and 474 deliveries after transplantation were identified. The risk of preeclampsia was increased (AOR: 7.4, 95% CI: 1.1-51.4,) after transplantation compared to prior to transplantation. No increased risk was found for congenital malformations or other outcomes when compared with pregnancies before transplantation or with the general population (2 511 506 births). Our results indicate an increased risk of preeclampsia mediated through the transplanted and immunosuppressed father. Importantly, no increased risk was found for other adverse obstetric outcomes or malformations, which may reassure male transplant recipients planning to father children.

Graft function 1 year after pregnancy in an islet-transplanted patient

Pancreatic islet transplantation is a treatment option for patients with type 1 diabetes (T1D), but pregnancy has generally not been advised for women after receiving an islet allograft. We hereby describe what is to our knowledge the first successful pregnancy and persistent graft function in a woman 4 years after her initial islet transplantation. A 37-year-old woman with brittle type 1 diabetes was transplanted with two separate islet graft infusions, eventually becoming insulin independent. Ten months after her second transplantation, her immunosuppression was switched from tacrolimus and sirolimus to tacrolimus, azathioprine, and prednisolone, due to her wish to become pregnant. She became pregnant one year later, and after 38 weeks of uncomplicated pregnancy, she gave birth to a healthy child by C-section. The current report suggests that pregnancy and childbirth can be accomplished after islet transplantation without loss of islet graft function.

[Management of side effects of targeted therapies in renal cancer: sexual disorders]

Since sexual disorders were not specifically studied in the principal series, epidemiological data is scarce. Nevertheless, in practice, when sexuality is dealt with during the monitoring of patients undergoing targeted therapies, more than half of the patients questioned say that they attach importance to their quality of sex life, despite the severity of their metastatic renal cancer. At the start of treatment, it is therefore important to inform patients of the possible occurrence of problems and to encourage them to report them. During treatment, screening for sexual disorders by questioning is desirable: desire, lubrication, dyspareunia, erectile dysfunction. In the event of the onset of a sexual disorder during treatment, it is not usually necessary to stop or modify the treatment. Therapeutic measures depend on the discomfort felt and are under the control of the specialist: erectile dysfunction, male libido disorders, vaginal dryness and vulvovaginitis. A consultation with an oncology psychologist and/or sex therapist is useful, if possible with the partner, based on the impact of the sexual problems.

Effects of embryonic cyclosporine exposures on brain development and behavior

Cyclosporine, a calcineurin inhibitor, is successfully used as an immunosuppressant in transplant medicine. However, the use of this pharmaceutical during pregnancy is concerning since calcineurin is thought to play a role in neural development. The risk for human brain development is difficult to evaluate because of a lack of basic information on the sensitive developmental times and the potentially pleiotropic effects on brain development and behavior. In the present study, we use zebrafish as a model system to examine the effects of embryonic cyclosporine exposures. Early embryonic exposures reduced the size of the eyes and brain. Late embryonic exposures did not affect the size of the eyes or brain, but did lead to substantial behavioral defects at the larval stages. The cyclosporine-exposed larvae displayed a reduced avoidance response to visual stimuli, low swim speeds, increased resting, an increase in thigmotaxis, and changes in the average distance between larvae. Similar results were obtained with the calcineurin inhibitor FK506, suggesting that most, but not all, effects on brain development and behavior are mediated by calcineurin inhibition. Overall, the results show that cyclosporine can induce either structural or functional brain defects, depending on the exposure window. The observed functional brain defects highlight the importance of quantitative behavioral assays when evaluating the risk of developmental exposures.

[Impact of end-stage renal disease and kidney transplantation on the reproductive system]

Chronic renal failure leads to many metabolic disorders affecting reproductive function. For men, hypergonadotropic hypogonadism, hyperprolactinemia, spermatic alterations, decreased libido and erectile dysfunction are described. Kidney transplantation improves sperm parameters and hormonal function within 2 years. But sperm alterations may persist with the use of immunosuppressive drugs. In women, hypothalamic-pituitary-ovarian axis dysfunction due to chronic renal failure results in menstrual irregularities, anovulation and infertility. After kidney transplantation, regular menstruations usually start 1 to 12 months after transplantation. Fertility can be restored but luteal insufficiency can persist. Moreover, 4 to 20% of women with renal transplantation suffer from premature ovarian failure syndrome. In some cases, assisted reproductive technologies can be required and imply risks of ovarian hyperstimulation syndrome and must be performed with caution. Pregnancy risks for mother, fetus and transplant are added to assisted reproductive technologies ones. Only 7 authors have described assisted reproductive technologies for patients with kidney transplantation. No cases of haemodialysis patients have been described yet. So, assisted reproductive technologies management requires a multidisciplinary approach with obstetrics, nephrology and reproductive medicine teams' agreement.

Pregnancy outcome and long-term follow-up after in vitro fertilization in women with renal transplantation

STUDY QUESTION

What is the child morbidity after IVF in women who have received a kidney transplant?

SUMMARY ANSWER

Overall, obstetric outcome and morbidity in children of women who had undergone renal transplantation and IVF treatment were favourable.

WHAT IS KNOWN ALREADY

There are several studies of the obstetric outcome in women with spontaneous conception after solid organ transplantation as well as studies of obstetric outcome after IVF in general. There are only a few case reports of women with kidney or pancreas-kidney transplantation and deliveries after IVF treatment.

STUDY DESIGN, SIZE, DURATION

A population-based retrospective register study was carried out in Sweden including all women with solid organ transplantation and deliveries after IVF; however, only women with kidney transplants were recruited. It also included information on all singleton deliveries after kidney transplantation and spontaneous conception between 1973 and 2012.

PARTICIPANTS/MATERIALS, SETTING AND METHODS

We cross-linked the IVF registers with the Medical Birth Register, the Patient Register and the Cause of Death Register. Study group 1 consisted of women with kidney transplantation and deliveries after IVF treatment. Study group 2 consisted of women with kidney transplantation and singleton deliveries after spontaneous conception. Group 3 (control group to singletons in study group 1) consisted of women without organ transplantation and with singleton deliveries after IVF, matched for maternal age, parity and date of birth. Group 4 (control group to study group 2) consisted of women without organ transplantation and with singleton deliveries after spontaneous conception, matched for maternal age, parity and year of birth.

MAIN RESULTS AND THE ROLE OF CHANCE

Seven singletons and one set of twins were born after organ transplantation and IVF. All women in this group had renal transplants. Among singletons, two (28.6%) were preterm births (PTB), one (14.3%) had very low birthweight (VLBW) (672 g) and one (14.3%) was small for gestational age (SGA). Two infants had minor birth defects. One woman developed pre-eclampsia (14.3%). Mean age at follow-up of the children was 9.7 years (SD 4.2). Two children were diagnosed with hyperactivity disorders. There were 199 singletons born after renal transplantation and spontaneous conception. The rates of pre-eclampsia (23.6%), PTB (48.5%), LBW (43.7%) and SGA (21.2%) were significantly higher in pregnancies of women with renal transplants who had conceived spontaneously than in pregnancies where there was no transplantation and conception was spontaneous. Neonatal morbidity, early neonatal and infant mortality were all significantly higher. No increase in birth defects was seen. Mean age at follow-up of the children was 14.7 years (SD 9.4). Acute bronchitis, systemic lupus erythematosus and hyperactivity disorders were more common in children delivered to women with renal transplantation than in children delivered to women with no transplanted organs. Otherwise, long-term child morbidity was comparable.

LIMITATIONS, REASONS FOR CAUTION

The women who had received renal transplants and who had given birth after IVF were a small group and may represent a selected group of comparatively healthy women.

WIDER IMPLICATIONS OF THE FINDINGS

The results are important to transplant recipients with infertility problems. Neonatal outcomes after maternal renal transplantation and spontaneous conception were in agreement with the literature. Long-term follow-up of this group of children has long been asked for and findings are included in this report.

STUDY FUNDING/COMPETING INTERESTS

No conflict of interest was reported. The study was supported by grants from Swedish Association of Local Authorities and Regions and by grants from the University of Gothenburg/Sahlgrenska University hospital (LUA/ALF 70940).
