Pregnancy outcomes in liver and cardiothoracic transplant recipients: a UK national cohort study

Long-term maternal outcomes of pregnancy after orthotopic liver transplantation in the Netherlands: A retrospective multicenter cohort study

Pregnancy after orthotopic liver transplantation (OLT) puts the mother, child, and transplanted organ at risk. Little is known about long-term outcomes. We performed a nationwide retrospective cohort study to evaluate short-term and long-term outcomes of post-OLT pregnancies. The secondary aim was to assess predictors for adverse pregnancy outcomes. A composite outcome of preeclampsia, preterm birth, low birth weight, and neonatal intensive care unit admission was made. Survival of women who received a transplant at <50 years of age with and without pregnancy after OLT were compared (Dutch Organ Transplantation Registry data). Descriptive statistics, regression analysis, Kaplan-Meier and log-rank analysis, and generalized estimating equation analysis were used. Among the included 70 women with 113 pregnancies >20 weeks of gestation, hypertension occurred in 20% and preeclampsia in 12%. The live birth rate was 87%; 33% were preterm, and 23% had low birth weight. Long-term follow-up (median 10 y [IQR: = 4-14]) showed small changes in serum creatinine and bilirubin ( p < 0.001). Sixteen mothers (23%) died during follow-up (median 8 y [IQR: = 4-12]), with all their children aged <18 years. No difference in survival was found when comparing women with and without pregnancy after OLT. The composite outcome occurred in 43/98 of pregnancies. Higher body mass index (BMI) and maternal age at conception increased the composite outcome risk (OR: 1.24, p < 0.01, and OR: 1.25, p = 0.01, respectively). To conclude, pregnancy after OLT does not seem to influence long-term outcomes of graft, kidney function, or patient survival in most cases. However, although pregnancy does not seem to impact survival after OLT, we do show that a substantial number of children will lose their mothers early in life. We believe this is important for pregnancy couseling of patients with an OLT and their partners.

Examining the impact of solid organ transplantation on family planning: pre- and post-transplantation pregnancy evaluations for both women and men

PURPOSE

The aim of this study was to collect and analyze information from pregnancies of organ transplanted women and partners of organ transplanted men. The goal was to enhance counseling regarding pregnancy planning and management and to enable more targeted monitoring to improve maternal and child health.

METHODS

In this retrospective, multicenter cohort study, women and men aged 18 to 45 who had undergone organ transplantation in Germany, Austria, and Switzerland were surveyed about their pregnancies before and after transplantation by using a self-developed questionnaire.

RESULTS

Even through transplanted women planned their pregnancies more carefully than before transplantation, they still experienced more pregnancy complications afterward. The live birth rate for pregnancies of partners of transplanted men, especially men who received a thoracic organ, was lower compared to before transplantation. Furthermore, this study showed that pregnancies of the partners of male transplant recipients occurred significantly less by spontaneous conception in comparison to pregnancies of transplanted women.

CONCLUSION

Pregnancies after organ transplantation are possible but associated with an increased risk of pregnancy complications. Therefore, early counseling for transplanted women and men who wish to have children, along with extensive monitoring during pregnancy, is necessary.

Immunosuppressive and immunomodulating therapy for atopic dermatitis in pregnancy: an appraisal of the literature

Atopic dermatitis (AD) is the most common dermatological diagnosis during pregnancy. Treatment of AD during pregnancy can be challenging, due to the unpredictable course and the fact that the therapy needs to be safe for both the mother and the fetus. Here we present an up-to-date appraisal of the literature on the treatment options available for AD in patients planning pregnancy, during pregnancy, and during breastfeeding. All patients with AD are recommended to supplement any medical treatment with daily applications of emollients. The first step in the medical treatment for AD during pregnancy are topical corticosteroids, and/or topical tacrolimus. If required, UV-light therapy can also be considered. Treatment with systemic therapy during pregnancy should always rely on a careful risk-benefit assessment and be based on shared-decision making between the treating physician and patient. The first-line systemic treatment option is cyclosporine A, whereas azathioprine may be considered in patients already receiving this treatment prior to pregnancy. Systemic glucocorticoids may also be used. Treatment with systemic JAK inhibitors is not recommended, whereas treatment with mycophenolate mofetil and methotrexate is contraindicated. Targeted therapy with dupilumab is not generally recommended, due to lack of experience in human pregnancies, yet some case-reports on their use are emerging. These recommendations are based on the authors appraisal of existing literature and the current recommendation from the European Task Force on Atopic Dermatitis. It is always the responsibility of the treating physician to stay updated on the newest guidelines and literature when treating patients with AD during pregnancy.

Counselling, Research Gaps, and Ethical Considerations Surrounding Pregnancy in Solid Organ Transplant Recipients

Survival after solid-organ transplantation has improved significantly, and many contemporary transplant recipients are of childbearing potential. There are limited data to guide decision-making surrounding pregnancy after transplantation, variations in clinical practice, and significant knowledge gaps, all of which raise significant ethical issues. Post-transplant pregnancy is associated with an increased risk of maternal and fetal complications. Shared decision-making is a central aspect of patient counselling but is complicated by significant knowledge gaps. Stakeholder interests can be in conflict; exploring these tensions can help patients to evaluate their options and inform their deliberations. We argue that uniform, evidence-based recommendations for pregnancy after solid organ transplantation are needed. Conducting research, including patient-engaged studies, in this area should be priority for the transplant community.

Safe pregnancy after liver transplantation: Evidence from a multicenter Italian collaborative study

BACKGROUND

Women who have undergone liver transplantation (LT) enjoy better health, and possibility of childbearing. However, maternal and graft risks, optimal immunosuppression, and fetal outcome is still to clarify.

AIM

Aim of the study was to assess outcomes of pregnancy after LT at national level.

METHODS

In 2019, under the auspices of the Permanent Transplant Committee of the Italian Association for the Study of the Liver, a multicenter survey including 14 Italian LT-centers was conducted aiming at evaluating the outcomes of recipients and newborns, and graft injury/function parameters during pregnancy in LT-recipients.

RESULTS

Sixty-two pregnancies occurred in 60 LT-recipients between 1990 and 2018. Median age at the time of pregnancy was 31-years and median time from transplantation to conception was 8-years. During pregnancy, 4 recipients experienced maternal complications with hospital admission. Live-birth-rate was 100%. Prematurity occurred in 25/62 newborns, and 8/62 newborns had low-birth-weight. Cyclosporine was used in 16 and Tacrolimus in 37 pregnancies, with no different maternal or newborn outcomes. Low-birth-weight was correlated to high values of AST, ALT and GGT.

CONCLUSION

Pregnancy after LT has good outcome; however, maternal complications and prematurity may occur. Compliance with the immunosuppression is fundamental to ensure the stability of graft function and prevent graft-deterioration.

Successful pregnancy outcome in patient with cardiac transplantation

Objectives

The population of female heart transplant recipients of reproductive age is increasing and pregnancy follow-up of these patients is important.

Case presentation

A 30-year-old patient who had a heart transplant due to viral myocarditis became pregnant spontaneously. A close follow-up by a multidisciplinary team allowed a normal pregnancy without maternal or fetal complications and the delivery of a healthy infant.

Conclusions

Successful pregnancy outcomes are possible in women who had a heart transplant. Careful and close surveillance by a multidisciplinary team is mandatory.

Usage of Tacrolimus and Mycophenolic Acid During Conception, Pregnancy, and Lactation, and Its Implications for Therapeutic Drug Monitoring: A Systematic Critical Review

BACKGROUND

Conception, pregnancy, and lactation following solid organ transplantation require appropriate management. The most frequently used immunosuppressive drug combination after solid organ transplantation consists of tacrolimus (Tac) plus mycophenolic acid (MPA). Here, the effects of Tac and MPA on fertility, pregnancy, and lactation are systematically reviewed, and their implications for therapeutic drug monitoring (TDM) are discussed.

METHODS

A systematic literature search was performed (August 19, 2019) using Ovid MEDLINE, EMBASE, the Cochrane Central Register of controlled trials, Google Scholar, and Web of Science, and 102 studies were included. Another 60 were included from the reference list of the published articles.

RESULTS

As MPA is teratogenic, women who are trying to conceive are strongly recommended to switch from MPA to azathioprine. MPA treatment in men during conception seems to have no adverse effect on pregnancy outcomes. Nevertheless, in 2015, the drug label was updated with additional risk minimization measures in a pregnancy prevention program. Data on MPA pharmacokinetics during pregnancy and lactation are limited. Tac treatment during conception, pregnancy, and lactation seems to be safe in terms of the health of the mother, (unborn) child, and allograft. However, Tac may increase the risk of hypertension, preeclampsia, preterm birth, and low birth weight. Infants will ingest very small amounts of Tac via breast milk from mothers treated with Tac. However, no adverse outcomes have been reported in children exposed to Tac during lactation. During pregnancy, changes in Tac pharmacokinetics result in increased unbound to whole-blood Tac concentration ratio. To maintain Tac concentrations within the target range, increased Tac dose and intensified TDM may be required. However, it is unclear if dose adjustments during pregnancy are necessary, considering the higher concentration of (active) unbound Tac.

CONCLUSIONS

Tac treatment during conception, pregnancy and lactation seems to be relatively safe. Due to pharmacokinetic changes during pregnancy, a higher Tac dose might be indicated to maintain target concentrations. However, more evidence is needed to make recommendations on both Tac dose adjustments and alternative matrices than whole-blood for TDM of Tac during pregnancy. MPA treatment in men during conception seems to have no adverse effect on pregnancy outcomes, whereas MPA use in women during conception and pregnancy is strongly discouraged.

Biochemical and clinical predictors in pregnant women with antiphospholipid syndrome and systemic lupus erythematosus: comprehensive update

BACKGROUND

Autoimmune diseases as antiphospholipid syndrome (APS) and systemic lupus erythematosus (SLE) could cause many maternal complications. The most common maternal complications of autoimmune diseases are lupus flare, hypertension, nephritis, preeclampsia (PE), eclampsia, and poor pregnancy outcomes which including preterm delivery and pregnancy loss. Only the lupus anticoagulant in the greatest prospective multicenter study has been associated with adverse pregnancy outcomes of the APS.

PURPOSE

This review aims to provide a comprehensive update for predictors in pregnant women with APS/SLE.

METHODS

These data have been collected from clinical and pathological studies, systematic reviews, and meta-analysis.

RESULTS

In recent years the SLE and APS demonstrated to have different and valuable clinical and biomarker predictors for the pregnancy outcome. Treatment of pregnant women with APS is low molecular weight heparin (LMWH) and aspirin; however, around 75% of this management is considered successful.

CONCLUSION

This review summarizes recent research that focuses on biochemical and clinical predictors of adverse pregnancy outcomes (APOs) of pregnant women with SLE and APS. Furthermore, we have collected more evidence that confirms the safety and efficacy of hydroxychloroquine (HCQ) preventing APOs.

Pregnancy care in solid organ transplant recipients

Recipients of solid organ transplants who become pregnant represent an obstetrically high-risk population. Preconception planning and effective contraception tailored to the individual patient are critical in this group. Planned pregnancies improve both maternal and neonatal outcomes and provide a window of opportunity to mitigate risk and improve lifelong health. Optimal management of these pregnancies is not well defined. Common pregnancy complications after transplantation include hypertension, preterm birth, infection, and metabolic disease. Multidisciplinary preconception and prepartum management, and counseling decrease complications and benefit the maternal-neonatal dyad.

Immunosuppressive and Immunomodulating Therapy for Atopic Dermatitis in Pregnancy: An Appraisal of the Literature

The aim of this appraisal of the literature is to elucidate the effects of immunosuppressive and immunomodulating agents used to treat atopic dermatitis (AD) on risk factors for fertility, pregnancy, and breastfeeding. Negative side effects of the psychological and physical stresses associated to AD flairs and uncontrolled AD are discussed, in order to evaluate the consequences of abstaining from treatment. Research on pregnancies in Danish women suggests a tendency towards an increased use of topical steroids and ultraviolet light therapy during pregnancy, compared to before conception, confirming the need for these patients to receive treatment, as well as decreased use of systemic treatments, suggesting a tendency towards undertreatment in this patient population. It is important that effective treatment be provided to pregnant women with AD. Here we present an appraisal of current knowledge on treatments for AD and the risks of exposure for the fetus and breastfed infant. Since little is known about the association between AD, pregnancy, and systemic treatment, we generalize conclusions based on studies on treatments of pregnant women who have undergone organ transplantation and who have inflammatory bowel disease, rheumatic disease, and autoimmune disease. The majority of recommendations are therefore based on a low or very low quality of evidence according to the GRADE system. The selected studies reflect the authors’ assessment regarding originality and importance in the context of this appraisal. It is always the treating doctor’s responsibility to stay updated on current literature when treating patients, especially pregnant patients.

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 outcomes in heart transplant recipients

BACKGROUND

The population of female heart transplant recipients of reproductive age is growing, and counseling regarding reproductive decisions is important. We describe maternal and fetal outcomes of pregnancy in the Transplant Pregnancy Registry International.

METHODS

Data regarding pregnancies between 1987 and 2016 were collected via questionnaires, phone interviews, and medical records review. Demographics, comorbidities, changes in immunosuppressive regimens, rejection episodes during pregnancy, data on maternal retransplants, and deaths were recorded.

RESULTS

A total of 91 patients reported 157 pregnancies. Mean maternal age at conception was 27 ± 5.6 years. The most common indications for transplant were congenital heart disease (22%) and viral myocarditis (18%). Average transplant to conception interval was 7 ± 6.1 years. Immunosuppression was calcineurin inhibitor-based in almost all patients, with 20% of recipients taking mycophenolic acid (MPA) while pregnant. Complications during pregnancy included pre-eclampsia (23%) and infections (14%). Rejection was reported during 9% of pregnancies and within 3 months postpartum in 7%. Livebirths occurred in 69%, with no neonatal deaths. Miscarriages occurred in 26% of pregnancies, 49% of which had MPA exposure. Mean follow-up post pregnancy was 8.9 ± 6.5 years. At last follow-up, 30 recipients had died, an average of 9.4 ± 6.2 years after pregnancy. The most common causes included allograft vasculopathy and rejection.

CONCLUSIONS

This is the largest reported series of pregnancies in heart transplant recipients and demonstrates that two thirds of pregnancies reported are successful. MPA exposure is associated with increased risk of teratogenicity and miscarriage. Pre-pregnancy counseling should include discussions of risk of MPA exposure, rejection, graft dysfunction, and maternal survival.

Pregnancy After Liver Transplantation: Outcomes From a Single-Center Experience

BACKGROUND/OBJECTIVES

Although much has been learnt regarding pregnancy after liver transplantation, data from India are scant. Hence, we evaluated the maternal and fetal outcomes of pregnancies after liver transplantation at our center.

METHODS

We conducted a retrospective review of all patients who underwent liver transplantation and later conceived at our center between 2006 and 2019.

RESULTS

Of the 750 liver transplantations performed at our center, 129 were female and 62 of them were in the childbearing age group (15-44 years). A total of seven conceptions occurred in seven patients during the study period. All the pregnancies occurred spontaneously. The median age of the patients at the time of liver transplantation and conception was 25 years (range, 24-33 years) and 29 years (range, 26-36 years), respectively. The median interval between transplantation and conception was 40 months (range, 7-48 months). All patients were on tacrolimus monotherapy. None of the patients had rejection during pregnancy despite a low median tacrolimus trough level of 2.7 ng/mL. Live birth (five cesarean and one normal) occurred in six of seven pregnancies at a median gestation age of 37.5 weeks. Mean birth weight was 3055.8 g (range, 2470-3635 g). Antenatal rubella infection and grade III intrauterine growth restriction resulting in still birth at 29 weeks occurred in one patient. The median postnatal follow-up was 25 months (range, 2-81 months). All babies and mothers were healthy.

CONCLUSIONS

Pregnancy after liver transplantation has a favorable outcome with a multidisciplinary team approach. There is a physiological reduction of tacrolimus trough levels during pregnancy for which dose augmentation is not usually required.

Obstetric outcomes among women with a liver transplant

BACKGROUND

Women with liver transplants may be at increased risk for adverse outcomes.

OBJECTIVE

The objectives of this study were to evaluate trends and provide recent data on outcomes for women with a liver transplant.

STUDY DESIGN

The National (Nationwide) Inpatient Sample (NIS) from the Healthcare Cost and Utilization Project from 1998 to 2014 was used for this repeated cross-sectional analysis. Women aged between 15 and 54 years, with a history of liver transplant who underwent delivery, antepartum, or postpartum hospitalizations were identified. Temporal trends in deliveries of women with liver transplants were analyzed. The risk for severe maternal morbidity (SMM) excluding transfusion based on criteria from the Centers for Disease Control and Prevention (CDC), as well as for individual outcomes including hypertensive diseases of pregnancy, postpartum hemorrhage, placental abruption, liver rejection, cesarean delivery, preterm delivery, and coagulopathy during delivery hospitalizations were analyzed. Risks of SMM during antepartum and postpartum hospitalizations were also analyzed. An adjusted log-linear regression model for SMM during delivery hospitalizations including demographic factors, hospital characteristics, and underlying comorbidity was performed. The chi-squared or Fisher's exact test was used for comparisons. Temporal trends were analyzed with the Cochran-Armitage trend test. Population weights were applied to create national estimates.

RESULTS

From 1998 to 2014, an estimated 1165 births occurred by women with a liver transplant. The number of births occurring by women with liver transplants increased over the study period from 1.0 per 100,000 in 1998-2000 to 2.8 per 100,000 in 2012-2014 (p < .01). The risk for CDC SMM excluding transfusion was significantly higher during delivery hospitalizations among women with compared to without liver transplant (8.0 versus 0.5%, p < .01, unadjusted risk ratio 15.4, 95% CI 12.7-18.6). Women with liver transplant were also at significantly higher risk for abruption (2.5 versus 1.0%, p = .03), hypertensive diseases of pregnancy (27.8 versus 6.9%, p < .01), postpartum hemorrhage (8.0 versus 2.8%, p = .01), cesarean delivery (51.7 versus 29.5%, p < .01), preterm delivery (27.5 versus 7.0%, p < .01), and coagulopathy (3.1 versus 0.3%, p < .01). A diagnosis of liver rejection was present during 4.1% of delivery hospitalizations for women with liver transplant. In the adjusted analysis for severe morbidity excluding transfusion risk was retained with liver transplant associated with increased likelihood of this adverse outcome (aRR 8.49, 95% CI 5.59-12.87). Women with liver transplants were at significantly higher likelihood of undergoing antepartum and postpartum admissions, and of experiencing SMM during these hospitalizations.

CONCLUSION

In this analysis of antepartum, delivery, and postpartum hospitalizations, women with liver transplant were at significantly higher risk for both SMM during all hospitalizations and for a range of adverse outcomes including placental abruption, hypertensive diseases of pregnancy, postpartum hemorrhage, cesarean delivery, and coagulopathy delivery during delivery hospitalizations. While deliveries to women with liver transplant were rare, these births became more frequent over the study period.

Management of reproductive health after cardiac transplantation

Pregnancy after cardiac transplantation poses immense challenges. Maternal risks include hypertensive disorders of pregnancy, rejection, and failure of the cardiac allograft that may lead to death. Fetal risks include potential teratogenic effects of immunosuppression and prematurity. Because of the high-risk nature of pregnancy in a heart transplant patient, management of reproductive health after cardiac transplantation should include preconception counseling to all women in the reproductive age group before and after cardiac transplantation. Reliable contraception is vital as nearly half of the pregnancies in this population are unintended. Despite the associated risks, successful pregnancies after cardiac transplantation have been reported. A multidisciplinary approach proposed in this review is essential for successful outcomes. A checklist for providers to guide management is provided.

European task force on atopic dermatitis position paper: treatment of parental atopic dermatitis during preconception, pregnancy and lactation period

Atopic dermatitis (AD) is a common inflammatory skin disease that affects both children and adults, including a large number of adults of reproductive age. Several guidelines for the treatment of AD exist, yet specific recommendations for the treatment of pregnant or lactating women and for adults planning to have a child are often lacking. This position paper from the European Task force on Atopic Dermatitis (ETFAD) is based on up-to-date scientific literature on treating pregnant and lactating women as wells as adults with AD planning to have a child. It is based on the expert opinions of members of the ETFAD and on existing safety data on the proposed treatments, many of which are derived from patients with other inflammatory diseases or from transplantation medicine. For treating future parents, as well as pregnant and lactating women with AD, the use of topical treatments including moisturizers, topical corticosteroids, tacrolimus, antiseptics such as chlorhexidine, octenidine, potassium permanganate and sodium hypochlorite (bleach) is deemed to be safe. Ultraviolet (UV) therapy may also be used. Systemic treatment should be prescribed only after careful consideration. According to the opinion of the ETFAD, treatment should be restricted to systemic corticosteroids and cyclosporine A, and, in selected cases, azathioprine.

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.

Stopping immunosuppressive treatment in autoimmune hepatitis (AIH): Is it justified (and in whom and when)?

BACKGROUND

Initial treatment of autoimmune hepatitis (AIH) with prednisolone ± azathioprine is based on randomised controlled trials. Many patients receive long-term immunosuppressive treatment to prevent disease relapse; this strategy has a weaker evidence base.

AIM

To consider whether immunosuppressive treatment (IST) withdrawal in AIH is justified and to develop a rationale for patient selection.

METHODS

We reviewed published papers between 1972 and 2018, which addressed the outcomes of IST withdrawal and/or complications of IST in AIH.

RESULTS

(1) AIH relapse rates after withdrawal of IST vary between 25% and 100%. There is heterogeneity in these studies regarding relapse definition, IST duration prior to withdrawal and criteria for biochemical and histological remission prior to withdrawal. (2) Factors associated with relapse following IST withdrawal include: (a) absence of an identifiable initial disease trigger, (b) presence of other autoimmune diseases, (c) longer time to biochemical remission and (d) elevated serum transaminases on treatment withdrawal. Reports of associations between relapse and age, IST duration and failure of histological remission have been inconsistent. (3) Continued IST reduces risk of AIH relapse over at least 5 years. However, there is no evidence that routine (as opposed to selective) long-term IST improves disease outcome. (4) Patients with AIH have an increased risk of extrahepatic cancer, notably non-melanoma skin cancer, to which long-term IST may contribute. Long-term corticosteroid therapy is associated with weight gain, low-trauma fractures, diabetes and possibly vascular disease.

CONCLUSIONS

While further studies are needed, evidence supports a strategy of IST withdrawal in some patients with AIH who have achieved remission.

Tacrolimus treatment for infertility related to maternal-fetal immune interactions

Many approaches have been used to achieve successful pregnancies in patients with infertility, though existing treatments remain unsatisfactory in patients with infertility caused by abnormal maternal-fetal immunity. However, our understanding of the immunological aspects of infertility has steadily progressed, aided by recent research into organ transplantation and cancer. The results of these recent analyses have led to the development and evaluation of several candidate immunological treatments, but the use of immunological treatments remains a novel approach. The current paper presents the hypothesis that tacrolimus may have potential as a candidate agent for the treatment of maternal-fetal immunity-related infertility.

Immunosuppressives and biologics during pregnancy and lactation : A consensus report issued by the Austrian Societies of Gastroenterology and Hepatology and Rheumatology and Rehabilitation

An increasing and early-onset use of immunosuppressives and biologics has become more frequently seen among patients with inflammatory bowel diseases (IBD) and rheumatic disorders. Many women in their childbearing years currently receive such medications, and some of them in an interdisciplinary setting. Many questions arise in women already pregnant or wishing to conceive with respect to continuing or discontinuing treatment, the risks borne by the newborns and their mothers and long-term safety. Together with the Austrian Society of Rheumatology and Rehabilitation, the IBD working group of the Austrian Society of Gastroenterology and Hepatology has elaborated consensus statements on the use of immunosuppressives and biologics in pregnancy and lactation. This is the first Austrian interdisciplinary consensus on this topic. It is intended to serve as a basis and support for providing advice to our patients and their treating physicians.

Use of synthetic and biologic DMARDs during pregnancy

Introduction: Since most of the autoimmune diseases (AID) affect mostly women in their fertile years, and fertility is in general preserved, the use of disease-modifying antirheumatic drugs (DMARDs) during conception, pregnancy, and lactation has been a matter of concern in the treatment of women affected by AID. Areas covered: We performed a comprehensive review of the latest and most relevant research papers published in the field and discussed different aspects related to the use of synthetic and biologic DMARDs and immunosuppressants in the preconceptional period, during pregnancy and lactation in AID patients, both in males and females. Expert commentary: Active AID impose an increased risk for adverse maternal and fetal outcomes, such as preeclampsia, miscarriage, intrauterine growth restriction, prematurity, low birth weight, and stillbirth. Family planning with proper contraception and shared decision-making on the ideal time to conceive with treatment adjustment must be a rule. One of the main challenges when counseling and/or adjusting treatment of patients that are planning a pregnancy is to provide a medication that is at the same time efficacious and safe at the conceptional period and to developing the fetus.

Pregnancy outcomes following single and repeat liver transplantation: An international 2-center cohort

Due to advances in obstetric and transplant medicine, women with a history of liver transplantation can have successful pregnancies. However, data on pregnancy outcomes is still limited, especially for women who have had a repeat liver transplant following graft rejection. This retrospective study compares pregnancy outcomes in women with single and repeat liver transplants managed at 2 tertiary hospitals in Toronto, Canada and Leuven, Belgium. We identified 41 pregnancies in 28 transplanted women, 6 of whom conceived following a second liver transplant after the first was rejected. Mean maternal age at delivery was 30 ± 7 years, and transplant-to-pregnancy interval was 8.5 ± 5.1 years. All women had normal liver function upon conception. Immunosuppressants included tacrolimus ± azathioprine (n = 26), cyclosporine (n = 4), and prednisone with immunosuppressants (n = 11). There were no maternal deaths. Maternal complications included hypertensive disorders of pregnancy (n = 10), deterioration in renal function (n = 6), gestational diabetes (n = 4), graft deterioration (n = 2), and anemia requiring blood transfusion (n = 1). Fetal/neonatal adverse outcomes included 2 miscarriages, 3 stillbirths, 1 neonatal death, 5 small-for-gestational-age infants, and 1 minor congenital anomaly. Mean gestational age at delivery was 36.7 ± 4.2 weeks. There were 14 (38.9%) preterm births. Outcomes in women with a second transplant were similar to those with a single transplant, except for a higher incidence of hypertensive disorders. In conclusion, with appropriate multidisciplinary care, stable graft function at pregnancy onset, and adherence to immunosuppressive regimens, women with single and repeat liver transplants have low rates of graft complications but remain at increased risk for pregnancy complications. Immunosuppressants and high-dose glucocorticoids can be safely used for maintenance of graft function and management of graft deterioration in pregnancy. Liver Transplantation 24 769-778 2018 AASLD.

Successful pregnancy outcomes following liver transplantation is predicted by renal function

Liver transplantation (LT) is a successful treatment for both acute liver failure and end-stage liver disease. The number of women of reproductive age undergoing LT is increasing. Pregnancy outcomes are favorable, but there is still a lack of prognostic markers. We aimed to identify factors predictive of adverse pregnancy outcomes in LT recipients. An analysis of all pregnancies occurring in LT recipients from 1989 to 2016 at King's College Hospital was performed. Clinical data of 162 conceptions in 93 women were reviewed. Descriptive and regression analyses were done to examine associations between laboratory markers and hepatological scores with pregnancy outcomes of live birth and preterm birth. Median age at LT was 23 years (range, 1-41 years), with a median age at conception of 30 years (range, 18-47 years). The live birth rate was 75% (n = 121). Of live births, 35% (n = 39/110 available) were delivered preterm. Preconception creatinine levels were higher in patients who had a preterm birth (85 versus 74 μmol/L; P = 0.008), with a preconception estimated glomerular filtration rate (eGFR) <90 mL/minute significantly associated with preterm delivery (P = 0.04). Progressive decline in eGFR predicted outcome, with gestational length declining with increasing chronic kidney disease (CKD) stage: CKD 0-1 = 39 weeks (median), CKD 2 = 37 weeks, and CKD 3 = 35 weeks. The risk of preterm birth was greatest in women with an eGFR <60 mL/minute (P = 0.004). Moreover, hypertension-related complications during pregnancy, such as gestational hypertension, preeclampsia, or eclampsia, were also associated with prematurity (P = 0.01). Women taking steroid-based immunosuppression had an increased risk of infection during pregnancy or postpartum (15% versus 4%; P = 0.02). In conclusion, although the majority of women have a successful pregnancy outcome after LT, preconception renal function predicts pregnancy outcome and steroids increase risk of infection during pregnancy or postpartum.

Pregnancy after heart transplantation: a well-thought-out decision? The Quebec provincial experience - a multi-centre cohort study

Despite reports of successful pregnancies in heart transplant (HTx) recipients, many centers recommend their patients against maternity. We reviewed our provincial experience of pregnancy in HTx recipients by performing charts review of all known gestations following HTx in the province of Quebec (Canada), stratified between planned and unplanned pregnancies. Long-term survival was compared to HTx recipient women of childbearing age who did not become pregnant. Eighteen pregnancies, 56% unplanned, occurred in eight patients, 10.1 (2.6-27.0) years after HTx. Immunosuppression was CNI-based, with a mean dose increase of 48.3% (tacrolimus) and 26.5% (cyclosporine), without rejection. Cardiometabolic complications were high compared to the general Canadian population, including preeclampsia (15.4% vs. 5.5%), hypertension (38.5% vs. 4.6%), and diabetes (15.4% vs. 5.6%). Mean gestational age was 35.1 (23.4-39.6) weeks (72.2% live births; 53.8% prematurity). Mean birthweight was 2418 (660-3612) g. Serum creatinine increased during pregnancy, becoming significant after delivery (P = 0.0239), and returning to preconception level in all but three patients within a year. After 4.6 (1.2-17.2) years of follow-up, two rejection episodes occurred in one patient. Long-term mortality was similar to overall HTx women (Kaplan-Meier; P = 0.8071). Pregnancy in HTx carries high cardiometabolic complications and decreased kidney function, but is feasible with acceptable outcomes and no impact on mother's survival.

Pregnancy after Solid Organ Transplantation

PURPOSE

To explore the reproductive decision-making process with women who were organ transplant recipients (renal, lung, & heart transplants).

STUDY DESIGN AND METHODS

Grounded theory guided data collection and analyses. Mixed methods with audiotaped telephone interviews and a written survey measuring social support were used. As social support is critical for women who are organ transplant recipients considering pregnancy, a search for disconfirming evidence for social support via a survey and interviews was included.

ANALYSES

Verbatim responses were analyzed through the constant comparative method using open, axial, and selective coding. Trustworthiness was established through prolonged engagement, member checking, and thick descriptions.

RESULTS

Participants included 10 women who were solid organ recipients (2 lung, 1 heart, and 7 renal transplant recipients). The core theme was Wanting a child. Other themes included Getting information, Advocating, Dealing with problems, Preparing, Talking, Supporting, Coping, and Advising others. There was no evidence of a lack of social support as evaluated via the survey or interviews.

CLINICAL IMPLICATIONS

This study provides new knowledge on clinical decision-making about pregnancy for women who are solid organ recipients and for healthcare professionals. Nurses can use these data to help guide women on how to obtain the most accurate information to make a personal decision about pregnancy and to develop support from their healthcare team and family.

What Is the Teratogenic Risk of Mycophenolate?

Mycophenolate is often used in the management of systemic lupus erythematosus. It has often been associated with significant fetal embryopathy, including fetal loss and multiple anomalies. The Food and Drug Administration has directed that women should be counseled regarding this prior to initiating treatment with this drug. Isolated total anomalous pulmonary venous return (TAPVR) is a rare association seen with its use in pregnancy.

Pregnancy Outcomes Related to Mycophenolate Exposure in Female Kidney Transplant Recipients

In 2012, the U.S. Food and Drug Administration issued guidelines advising kidney transplant recipients (KTRs) to discontinue mycophenolate (MPA) in preparation for pregnancy. Little is known about how this guidance has affected pregnancy and graft outcomes. The purpose of this retrospective cohort study was to investigate any association between the discontinuation of MPA and KTR pregnancy and graft outcomes. Data from the National Transplantation Pregnancy Registry included 382 cases in which KTRs managed on MPA became pregnant. Overall, 22 variables, including the time in which a KTR discontinued MPA, were assessed across four end points: miscarriages, birth defects, and 2- and 5-year postpartum graft loss. Birth defects and miscarriages were similar among KTRs who discontinued MPA >6 and <6 weeks prior to pregnancy and during the first trimester. In contrast, discontinuing MPA during the second trimester or later significantly increased the risk of miscarriages (odds ratio [OR] 9.35, 95% confidence interval [CI] 4.31-20.00, p < 0.001) and birth defects (OR 6.06, 95% CI 1.96-18.87, p = 0.002). Discontinuing MPA <6 weeks prior to pregnancy was associated with an increased risk of 5-year graft loss. For the fetus, there is value to discontinuing MPA anytime prior to the second trimester. Adhering to current guidelines does not negatively affect graft survival.

Critical review of the current recommendations for the treatment of systemic inflammatory rheumatic diseases during pregnancy and lactation

The crucial issue for a better pregnancy outcome in women with autoimmune rheumatic diseases is appropriate planning, with counseling of the ideal timing and treatment adaptation. Drugs used to treat rheumatic diseases may interfere with fertility or increase the risk of miscarriages and congenital abnormalities. MTX use post-conception is clearly linked to abortions as well as major birth defects, so it should be stopped 3months before conception. Leflunomide causes abnormalities in animals even in low doses. Although in humans, it does not seem to be as harmful as MTX, when pregnancy is detected in a patient on leflunomide, cholestyramine is given for washout. Sulfasalazine can be used safely and is an option for those patients who were on MTX or leflunomide. Azathioprine is generally the immunosuppressive of choice in many high-risk pregnancy centers because of the safety profile and its steroid-sparing property. Cyclosporine and tacrolimus can also be used as steroid-sparing agents, but experience is smaller. Although prednisone and prednisolone are inactivated in the placenta, we try to limit the dose to the minimal effective one, to prevent side effects. Antimalarials have been broadly studied and are safe during pregnancy and breastfeeding. Among biologic disease modifying anti-rheumatic agents (bDMARD), the anti-TNFs that have been used for longer are the ones with greater experience. The large monoclonal antibodies do not cross the placenta in the first trimester, and after conception, the decision to continue medication should be taken individually. The experience is larger in women with inflammatory bowel diseases, where anti-TNF is generally maintained at least until 30weeks to reduce fetal exposure. Live vaccines should not be administrated to the infant in the first 6months of life. Pregnancy data for rituximab, abatacept, anakinra, tocilizumab, ustekinumab, belimumab, and tofacitinib are limited and their use in pregnancy cannot currently be recommended.

The EULAR points to consider for use of antirheumatic drugs before pregnancy, and during pregnancy and lactation

A European League Against Rheumatism (EULAR) task force was established to define points to consider on use of antirheumatic drugs before pregnancy, and during pregnancy and lactation. Based on a systematic literature review and pregnancy exposure data from several registries, statements on the compatibility of antirheumatic drugs during pregnancy and lactation were developed. The level of agreement among experts in regard to statements and propositions of use in clinical practice was established by Delphi voting. The task force defined 4 overarching principles and 11 points to consider for use of antirheumatic drugs during pregnancy and lactation. Compatibility with pregnancy and lactation was found for antimalarials, sulfasalazine, azathioprine, ciclosporin, tacrolimus, colchicine, intravenous immunoglobulin and glucocorticoids. Methotrexate, mycophenolate mofetil and cyclophosphamide require discontinuation before conception due to proven teratogenicity. Insufficient documentation in regard to fetal safety implies the discontinuation of leflunomide, tofacitinib as well as abatacept, rituximab, belimumab, tocilizumab, ustekinumab and anakinra before a planned pregnancy. Among biologics tumour necrosis factor inhibitors are best studied and appear reasonably safe with first and second trimester use. Restrictions in use apply for the few proven teratogenic drugs and the large proportion of medications for which insufficient safety data for the fetus/child are available. Effective drug treatment of active inflammatory rheumatic disease is possible with reasonable safety for the fetus/child during pregnancy and lactation. The dissemination of the data to health professionals and patients as well as their implementation into clinical practice may help to improve the management of pregnant and lactating patients with rheumatic disease.

Outcomes of pregnancy following liver transplantation: The King's College Hospital experience

Reports of pregnancy in liver transplantation (LT) patients have largely favorable outcomes. Concerns remain with regards to maternal and graft risk, optimal immunosuppression (IS), and fetal outcomes. We review all post-LT pregnancies at our center with regard to the outcomes and safety for the patient, graft, and fetus. A total of 117 conceptions occurred in 79 patients. Median age at conception was 29 years. Maternal complications included graft loss (2%), acute cellular rejection (ACR; 15%), pre-eclampsia/eclampsia (15%), gestational diabetes (7%), and bacterial sepsis (5%). ACR was significantly more common in those women who conceived within 12 months of LT (P = 0.001). The live birth rate was 73%. Prematurity occurred in 26 (31%) neonates, and 24 (29%) neonates were of low or very low birth weight. IS choice (cyclosporine versus tacrolimus) had no significant effect on pregnancy outcomes and complications. No congenital abnormalities occurred, and only 1 child born at 24 weeks had delayed developmental milestones. In conclusion, pregnancy following LT has a favorable outcome in the majority, but severe maternal risks remain. Patients should be counseled with regard to the above information so informed decisions can be made, and pregnancy must be considered high risk with regular monitoring by transplant clinicians and specialist obstetricians.

Update on the Teratogenicity of Maternal Mycophenolate Mofetil

Mycophenolic acid (MPA) products, namely mycophenolate mofetil and mycophenolate sodium, are immunosuppressive medications used to prevent rejection in solid organ transplant recipients and to treat various autoimmune disorders. Mycophenolate therapy is considered to be teratogenic based on observational studies of pregnancies exposed to MPA, which demonstrated an increased incidence of miscarriages in pregnancies exposed to MPA during their first trimester and a pattern of birth defects in the offspring of some pregnancies exposed to MPA. Herein, we have detailed case and series reports in a comprehensive literature review summarizing what is known to date regarding fetal exposure to MPA. Based on evidence from the literature, results of postmarketing surveillance, and information from registries such as the National Transplantation Pregnancy Registry in the United States, it is advised that pregnancy be avoided by women taking MPA. Preconception planning offers the opportunity to explore the alternatives to protect the mother, her transplanted organ, and minimize fetal risk. How to proceed in cases of unplanned pregnancies exposed to MPA in transplant recipients is a complex issue. Research involving large epidemiological studies is expected to be sparse as women heed the warnings about becoming pregnant on MPA. Published recommendations for managing MPA in women of childbearing potential include discontinuing the medication prior to conception, switching the MPA to another medication, or discontinuing the MPA when the pregnancy is discovered.

Challenges in cardiology research in pregnancy

ABSTRACT 

Research in pregnancy is challenging as it involves a special ‘vulnerable’ group due to the involvement of the mother and the fetus. These challenges, which are inherent in studying pregnancy in physiologic and pathologic states, have contributed to the scant research in pregnancy. Until recently, most studies in pregnancy were nonrandomized and retrospective in nature, representing prevailing clinical standards of practice and clinicians’ biases. Prospective studies were generally limited to single centers, comprising of small sample sizes and were observational in nature, rather than randomized studies involving therapy. Ethical and legal factors, research mandates, patient factors, the protracted nature of pregnancy, institutional commitment to research, interdisciplinary clinical and research collaboration, funding support, administrative issues and the level of involvement of national cardiac and obstetric and gynecological societies have been barriers to research in pregnancy in developed countries. Even prospective observational studies are difficult to perform due the difficulties involved with obtaining consent, study recruitment and follow-up. Misconceptions regarding research have led to a lack of participation by women. The longitudinal nature of prospective studies in pregnancy, the problems associated with enrolling women before pregnancy and in the first trimester and the failure to understand the commitment required by the patient, as well as many social factors, have led to increased drop-out rates during pregnancy, as well as difficulty with follow-up in the post-partum state. These factors, along with the failure to supplement funding support due to longer study periods than anticipated, have led to studies of small sample sizes. Understanding patient factors that lead to a lack of participation in research or dropping out following initial consent could help make research participation more conducive for pregnant women. The involvement of national societies in the planning and funding of multicenter studies, interdepartmental and interinstitutional collaboration, institutional and extramural funding support and patient incentives are crucial for shortening study duration and ensuring adequacy of sample sizes for successful research in pregnancy. National health service structures, such as those found in Europe and Canada, makes multicenter collaboration for prospective studies more feasible than for countries such as the USA, in which the fees-for-service system is used. Utilization of telemedicine and handheld ultrasound systems and participation in prospective multicenter registries could not only improve the clinical care of pregnant women in underdeveloped countries, but also provide a platform for research during pregnancy. Multicenter and even global registries supported by European cardiac societies have been formed recently that are beginning to bring forth much-needed data regarding pathological states, such as peripartum cardiomyopathy and pregnancy in congenital heart disease. Such studies are largely confined to non-US countries and have started seeing participation from underdeveloped countries. Studies on pregnancy in connective tissue disorders, older women, post-chemoradiation therapy or organ transplantation and in the HIV state remain limited.
