Pregnancy after Lung Transplant

Pregnancy and fertility in people with cystic fibrosis following lung transplantation

PURPOSE OF REVIEW

The purpose of this review is to summarize available data on fertility, fertility preservation, pregnancy and parenthood following lung transplantation for people with cystic fibrosis (pwCF).

RECENT FINDINGS

In the era of cystic fibrosis transmembrane conductance regulator (CFTR) modulator use, oral therapies that positively impact fundamental CFTR protein abnormalities, the number of pregnancies has increased dramatically with a concomitant decrease in lung transplantation. Nonetheless, some pwCF still require lung transplantation as a life-saving measure, and a fraction of those individuals desires parenthood. Cystic fibrosis (CF) providers infrequently discuss fertility preservation with pwCF, and pwCF feel uneducated about their fertility options posttransplant. However, because the immunosuppression required to successfully maintain lung allografts may impact future fertility, pwCF should receive genetic and reproductive counseling prior to lung transplantation. While pregnancies posttransplantation are high-risk, selected females with CF may be able to pursue this path to parenthood.

SUMMARY

Although there is a paucity of data specific to pwCF who have undergone lung transplantation, recently developed general guidelines should inform discussions regarding fertility, pregnancy and parenthood in pwCF who desire parenthood following lung transplantation for optimal shared decision-making.

First Successful Pregnancy After Lung Transplantation in Poland-Case Report

INTRODUCTION

Lung transplantation is well-established treatment for patients with advanced lung dysfunction in cystic fibrosis (CF). Pregnancy in CF lung transplant recipients is feasible, although it still remains challenging for even professionals and demands a multidisciplinary approach.

CASE REPORT

We report the case of pregnancy in a 22-year-old woman after lung transplantation (LTx) due to end-stage respiratory failure in the course of CF. The interval from transplant to conception was 2.5 years. In 2019, orthotopic LTx was performed and a 3-drug immunosuppressive scheme was used-tacrolimus, mycophenolate mofetil, and prednisolone. There were no complications in the postoperative course. In April 2022, the patient was confirmed pregnant. All fetotoxic or teratogenic drugs were discontinued. Throughout the whole pregnancy, the patient was regularly monitored in the transplant and obstetrics centers. Due to the vaginal bleeding and irregular contractions at the 33 weeks of pregnancy, the course of steroids was administered. At 38 weeks and 5 days of gestation, she presented premature rupture of membranes. The caesarean section was performed because of breech presentation of the fetus. A live, term daughter was born and according to the screening test she does not have CF. Currently, 12 months after the delivery, the mother's lung function is good.

CONCLUSIONS

Getting pregnant and having a safe pregnancy after LTx is possible, but it requires a specialized and individual approach. The patient should be well informed about possible complications and risks including graft failure. The patient's attitude and her cooperation with doctors play a major role.

A single center Israeli experience in pregnancy post lung transplantation: Feasibility of successful two or more full-term pregnancies in individual lung transplant recipients

INTRODUCTION

Female lung transplant recipients (LTRs) of reproductive age are increasingly considering pregnancy due to advances in post-transplant management and improved survival. We report our experience with pregnancy in LTRs, with an emphasis on two or more successful full-term pregnancies in individual transplant recipients.

METHODS

We conducted a retrospective analysis of pregnancies in LTRs at our transplant center and collected maternal and fetal outcomes.

RESULTS

In our patient cohort, eight female LTRs conceived a total of 17 pregnancies, resulting in 13 newborns, 12 at full term, and 11 with a birth weight > 2.5 kg. Three of the LTRs had two or more successful full-term pregnancies. LTRs required a significant tacrolimus dose increase to maintain target trough levels during pregnancy. Six recipients are currently clinically stable and active, three with lung function comparable to pre-pregnancy values, and three with evidence of chronic lung allograft dysfunction (CLAD), but stable lung function. Two of the eight LTRs died subsequent to childbirth secondary to chronic respiratory failure due to CLAD, at a mean of 11 years post-transplantation and a mean of 4.5 years after childbirth.

CONCLUSION

Pregnancy following lung transplantation is feasible and can be achieved with acceptable maternal and newborn outcomes. Importantly, LTRs can successfully have two or more full-term pregnancies.

Reproductive health after thoracic transplantation: An ISHLT expert consensus statement

Pregnancy after thoracic organ transplantation is feasible for select individuals but requires multidisciplinary subspecialty care. Key components for a successful pregnancy after lung or heart transplantation include preconception and contraceptive planning, thorough risk stratification, optimization of maternal comorbidities and fetal health through careful monitoring, and open communication with shared decision-making. The goal of this consensus statement is to summarize the current evidence and provide guidance surrounding preconception counseling, patient risk assessment, medical management, maternal and fetal outcomes, obstetric management, and pharmacologic considerations.

A survey of solid organ transplant recipient attitudes and concerns regarding contraception and pregnancy

INTRODUCTION

Many women who are solid organ transplant (SOT) recipients wish to have children after transplantation. Contraception is an important component of post-transplant planning and care, given the increased risk associated with post-transplant pregnancies. We sought to understand patient attitudes and concerns about post-transplant contraception and pregnancy.

METHODS

Following a comprehensive literature review, our team developed a survey that was administered to female SOT recipients of childbearing age. We used descriptive and inferential statistics to characterize participant views RESULTS: A total of 243 transplant recipients completed the survey (80.7% response rate). The mean age of respondents was 37.5 years (±8.1 years), 66.7% were kidney recipients, and 40.7% were within the first year after transplant. The most common concerns among respondents included fetal and maternal health complications. Participants generally did not agree that transplant recipients should be advised to avoid pregnancy. There was strong support for shared decision-making about pregnancy after transplantation CONCLUSION: Understanding patient perspectives can help transplant providers make better care recommendations and support patient autonomy in reproductive decisions post-transplant. Given that there are some differences in views by transplant type, individualized conversations between patients and providers are needed.

Pregnancy in Cystic Fibrosis-Past, Present, and Future

The introduction of mutation-specific therapy led to a revolution in cystic fibrosis (CF) care. These advances in CF therapies have changed the disease profile from a severe incurable disease with limited survival to a treatable disease with improved quality of life and survival into adulthood. CF patients are now able to plan their future, including marriage and parenthood. Side by side with the optimism, new issues and concerns are arising, including fertility and preparation for pregnancy, maternal and fetal care during pregnancy, and post-partum care. While cystic fibrosis transmembrane regulator (CFTR) modulators show promising results for improving CF lung disease, data on their safety in pregnancy are still limited. We performed a literature review on pregnancy in CF from the past, with the first described pregnancy in 1960, through the current fascinating changes in the era of CFTR modulators, to ongoing studies and future directions. Current advances in knowledge give hope for improved outcomes of pregnancy, towards the best possible prognosis for the mother and for the baby.

The obstetric implications of pulmonary hypertension and lung transplant

Pulmonary hypertension (PH) is present when the mean pulmonary artery pressure is elevated to >20 mmHg as determined by right heart catheterization. It is categorized into five groups according to the underlying causes. Its presence is considered a contraindication to pregnancy for which therapeutic termination is usually advised due to grave maternal prognosis and pregnancy outcome. Nevertheless, pregnancies in affected women are increasingly reported, about half of which were unplanned, and two-thirds resulted in live births without increased foetal anomalies, notwithstanding increased risks of preterm birth, low birth weight, pre-eclampsia, other obstetric complications, and medical comorbidities, when managed under a multidisciplinary team in specialized centres. Successful lung transplant, the ultimate treatment for PH and other progressive lung diseases, restores fertility, and pregnancy is increasingly encountered, but there is a higher risk of graft rejection and mortality, compared with recipients of other organs. Preconception assessment is vital in optimizing maternal and pregnancy outcomes.

Pregnancies and Gynecological Follow-Up after Solid Organ Transplantation: Experience of a Decade

In recent years, solid organ transplantations, such as kidney or lung grafts, have been performed worldwide with an improvement of quality of life under immunosuppressive therapy and an increase in life expectancy, allowing young women to consider childbearing. In the current study, we conduct a retrospective study in two French centers for kidney and lung transplantations to evaluate the rate and outcomes of pregnancies, contraception and gynecological monitoring for women under 40 years old who underwent solid organ transplantation. Among 210 women, progestin was the most widely used contraceptive method. Of the 210 women, 24 (11.4%) conceived 33 pregnancies of which 25 (75.8%) were planned with an immunosuppressant therapy switch. Of the 33 pregnancies, 7 miscarried (21.2%) and 21 (63.7%) resulted in a live birth with a high rate of pre-eclampsia (50%). No graft rejections were observed during pregnancies. Among the deliveries, 19 were premature (90.5%, mostly due to induced delivery) and the C-section rate was high (52.4%). No particular pathology was identified among newborns. We conclude that pregnancies following solid organ transplantation are feasible, and while they are at an increased risk of pre-eclampsia and prematurity, they should still be permitted with close surveillance by a multidisciplinary care team.

Follow-Up of Offspring Born to Parents With a Solid Organ Transplantation: A Systematic Review

Pregnancy after solid organ transplantation (SOT) has potential risks for the offspring. Most existing research focused on short-term pregnancy outcomes. The aim of this systematic review was to evaluate available data concerning longer term outcomes (>1 year) of these children. A systematic literature search, following PRISMA guidelines, of PubMed and Embase was performed from the earliest date of inception through to 6th April 2022. Publications on all types of (combined) SOT were eligible for inclusion. In total, 53 articles were included. The majority assessed offspring after kidney (78% of offspring) or liver transplantation (17% of offspring). 33 studies included offspring aged >4 years and five offspring aged >18 years. One study was included on fathers with SOT. The majority of the 1,664 included children after maternal SOT had normal intellectual, psychomotor, and behavioral development. Although prematurity and low birth weight were commonly present, regular growth after 1 year of age was described. No studies reported opportunistic or chronic infections or abnormal response to vaccinations. In general, pregnancy after SOT appears to have reassuring longer term outcomes for the offspring. However, existing information is predominantly limited to studies with young children. Longer prospective studies with follow-up into adulthood of these children are warranted.

Management of pregnancy in cystic fibrosis

With recent therapeutic advances in care, people with cystic fibrosis (CF) are living longer and healthier lives. Development of the cystic fibrosis transmembrane conductance regulator (CFTR) modulator therapies has led to improved function of the CFTR protein resulting in improved lung function, decreased rates of pulmonary exacerbations and improved nutritional status for the majority of people with CF. Given improved quality and quantity of life, more people with CF are considering becoming pregnant than ever before. Since the first reported pregnancy in a woman with CF in 1960, the management of pregnancy in CF has been of increased interest and is an active field of research. In this review, we aim to discuss the management of pregnancy in CF. We discuss the optimisation of preconception health, management of maintenance CF therapies, and use of CFTR modulators during pregnancy and lactation. We also describe the management of pulmonary exacerbations during pregnancy as well as the unique management of pregnancy in a post-transplant patient with CF.

Educational aims

To describe considerations for optimisation of preconception health.To describe the management of chronic CF therapies including CFTR modulators during pregnancy and lactation.To describe treatment of an acute pulmonary exacerbation during pregnancy.To describe the management of pregnancy in individuals with CF following organ transplantation.

[Parenthood challenged by cystic fibrosis. Experience of affected parents]

INTRODUCTION

Medical progress affords patients with cystic fibrosis (CF) the opportunity to become parents.

OBJECTIVE

To assess the psychological issues of parenthood in persons with cystic fibrosis.

MATERIAL AND METHODS

Semi-structured interviews on parenthood, conducted by a psychologist with CF parents treated at the Cystic Fibrosis Center and the Transplantation Center of Foch hospital (Suresnes, France).

RESULTS

Twenty-one (21) fathers and 22 mothers participated ; 84 % had become parents through pregnancy, 14% via adoption and one woman by means of surrogacy; 73% of the women and 67% of the men had done so prior to lung transplantation, while 25% had achieved parenthood without or against medical advice. As parents, they suffered from a lack of familial and medical support for their parental projects and a lack of recognition of their reproductive difficulties.

CONCLUSION

While the desire for a child may be initially repressed by potentially life-threatening risks, a loving couple with a satisfying sexual life may in many instances surmount the repression and express the desire, which is not only the desire for a potentially life-bearing body, but also the desire to start a family.

Family-building and parenting considerations for people with cystic fibrosis

As people with cystic fibrosis (CF) live longer and healthier lives, increasing numbers are considering the full range of reproductive options for their futures, including parenthood, pregnancy, or pregnancy prevention. As the face of CF changes, the CF care model must adapt to meet the reproductive health needs of both parents and nonparents with CF. This article summarizes the reproductive goals and family-building concerns faced by people with CF, including fertility, pregnancy, and alternative paths to parenthood, the impact of parenthood on mental and physical health, and important future research.

Bilateral lung transplantation during pregnancy after ECMO for influenza-A caused ARDS

Pregnant women with influenza-A have an increased risk of developing acute respiratory distress syndrome (ARDS). Extracorporeal membrane oxygenation (ECMO) can be used as salvage therapy, with lung transplantation as a therapeutic option. However, successful bilateral lung transplantation during pregnancy has never been reported before. We herein report the case of a 34-year-old primipara, who was diagnosed with ARDS caused by influenza-A-induced pneumonia at early gestation. After considering all possible therapeutic options and being fully dependent on VV-ECMO support, she underwent bilateral lung transplantation. The transplantation with intraoperative central VA-ECMO support was successfully performed with good recovery after an initial primary graft dysfunction. The pregnancy was prolonged until 29⁺⁵  gestational weeks. The newborn exhibited growth retardation and was initially stabilized, but later died due to severe, hypoxic respiratory failure and pulmonary hypertension. In conclusion, lung transplantation is a possible salvage therapy for patients with severe lung failure following ARDS during pregnancy. However, it places the mother and unborn child at risk. A multi-professional approach is warranted to diagnose and treat complications at an early stage.

Pregnancy in cystic fibrosis: Review of the literature and expert recommendations

Cystic fibrosis (CF) was historically a disease largely afflicting children. Due to therapeutic advancements, there are now more adults with CF than children. In the past decade, medications including Cystic Fibrosis Transmembrane conductance Regulator (CFTR) modulators became available that treat the underlying cause of CF and are dramatically improving lung function as well as quality and quantity of life for people with CF. As a result, more women with CF are becoming pregnant. We gathered a panel of experts in CF care, family planning, high risk obstetrics, nutrition, genetics and women with CF to review current literature on pregnancies and to provide care recommendations for this unique population.

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.

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.

Cystic fibrosis foundation consensus statements for the care of cystic fibrosis lung transplant recipients

Cystic fibrosis (CF) is the indication for transplantation in approximately 15% of recipients worldwide, and Cystic Fibrosis Lung Transplant Recipients (CFLTRs) have excellent long-term outcomes. Yet, CFLTRs have unique comorbidities that require specialized care. The objective of this document is to provide recommendations to CF and lung transplant clinicians for the management of perioperative and underlying comorbidities of CFLTRs and the impact of transplantation on these comorbidities. The Cystic Fibrosis Foundation (CFF) organized a multidisciplinary committee to develop CF Lung Transplant Clinical Care Recommendations. Three workgroups were formed to develop focused questions. Following a literature search, consensus recommendations were developed by the committee members based on literature review, committee experience and iterative revisions, and in response to public comment. The committee formulated 32 recommendation statements in the topics related to infectious disease, endocrine, gastroenterology, pharmacology, mental health and family planning. Broadly, the committee recommends close coordination of care between the lung transplant team, the cystic fibrosis care center, and specialists in other disciplines with experience in the care of CF and lung transplant recipients. These consensus statements will help lung transplant providers care for CFLTRs in order to improve post-transplant outcomes in this population.

ERS/TSANZ Task Force Statement on the management of reproduction and pregnancy in women with airways diseases

This European Respiratory Society/Thoracic Society of Australia and New Zealand statement outlines a review of the literature and expert opinion concerning the management of reproduction and pregnancy in women with airways diseases: asthma, cystic fibrosis (CF) and non-CF bronchiectasis. Many women with these diseases are now living into reproductive age, with some developing moderate-to-severe impairment of lung function in early adulthood. The statement covers aspects of fertility, management during pregnancy, effects of drugs, issues during delivery and the post-partum period, and patients' views about family planning, pregnancy and parenthood. The statement summarises current knowledge and proposes topics for future research, but does not make specific clinical recommendations.

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

Pulmonary Complications of Obstetric and Gynecologic Conditions

The respiratory and the female reproductive systems are not embryologically or functionally related. However, the reproductive system can exert significant effects on the respiratory system as a result of the various hormonal changes that occur during a woman’s menstrual cycle and especially during pregnancy. In addition, there are several unique gynecologic and/or obstetric conditions that can directly affect the respiratory system. The following chapter reviews the effects of pregnancy on the respiratory system, as well as the special issues concerning the management of common respiratory conditions (e.g., pneumonia, asthma) during pregnancy. In addition it reviews several gynecologic disorders with unique pulmonary complications.

Pregnancy after lung transplant

Improved survival now means that more women with lung transplants than ever before, many of whom have a diagnosis of cystic fibrosis, may be able to consider pregnancy. However, lung transplant recipients have increased risk of maternal and neonatal complications associated with pregnancy [1]. These pregnancies should be planned in advance and closely monitored. Pregnancy should be avoided for a minimum of 1–2 years after transplant to minimise episodes of acute rejection and achieve the lowest possible doses of immunosuppressive drugs. Immunosuppression with mycophenolate mofetil and mammalian target of rapamycin (mTOR) inhibitors should be avoided because of teratogenic effects. Immunosuppression based on prednisolone, azathioprine and calcineurin inhibitors should be established before conception. Vaginal delivery is encouraged due to the lower risk of infection and adverse events of general anaesthesia that may occur with caesarean delivery. Breast feeding is discouraged because of the risk of infant exposure to immunosuppressive drugs via breast milk, though remain a controversial recommendation. We present a patient who had successful pregnancy after lung transplant for cystic fibrosis.

Pregnancy and cystic fibrosis: Approach to contemporary management

Over the previous 50 years survival of patients with cystic fibrosis has progressively increased. As a result of improvements in health care, increasing numbers of patients with cystic fibrosis are now considering starting families of their own. For the health care professionals who look after these patients, the assessment of the potential risks, and the process of guiding prospective parents through pregnancy and beyond can be both challenging and rewarding. To facilitate appropriate discussions about pregnancy, health care workers must have a detailed understanding of the various important issues that will ultimately need to be considered for any patient with cystic fibrosis considering parenthood. This review will address these issues. In particular, it will outline pregnancy outcomes for mothers with cystic fibrosis, issues that need to be taken into account when planning a pregnancy and the management of pregnancy for mothers with cystic fibrosis or mothers who have undergone organ transplantation as a result of cystic fibrosis.

Outcomes after pregnancy in living lobar lung transplantation

Pregnancy after lung transplantation has been described, but pregnancy after living donor lobar lung transplantation (LDLT) has not been reported. The aim of this study was to evaluate outcomes after pregnancy with LDLT and discuss current recommendations regarding pregnancy and lung transplantation. A total of four LDLT patients and five pregnancies were identified, all from our institution. No patient has developed worsening pulmonary function or acute or chronic rejection. The complications of pulmonary hypertension and rejection may be overestimated in this population, and recommendations for preventive sterilization at transplantation or abortion at the time of conception are likely unwarranted and unnecessary.

Pregnancy after heart and lung transplantation

Patients awaiting transplantation should be counseled regarding posttransplant contraception and the potential adverse outcomes associated with posttransplant conception. Pregnancy should be avoided for at least 1-2 years post transplant to minimize the risks to allograft function and fetal well-being. Transplant patients, particularly lung transplant recipients, have an increased risk of maternal and neonatal pregnancy-related complications, including prematurity and low birth weight, postpartum graft loss, and long-term morbidity and mortality compared to other solid-organ recipients. Therefore, careful monitoring by a specialized transplant team is crucial. Maintenance of immunosuppression is recommended, except for mycophenolate and mammalian target of rapamycin inhibitors (mTORi), which should be replaced before conception. Immunosuppressants must be regularly monitored and dosing adjusted to avoid graft rejection. Monitoring during labor is mandatory and epidural anesthesia recommended. Vaginal delivery should be standard and cesarean delivery only performed for obstetric reasons. Breastfeeding poses risks of neonatal exposure to immunosuppressants and is generally contraindicated.

Risk of obstetrical complications in organ transplant recipient pregnancies

Pregnancy after kidney and liver transplantation is becoming relatively common, although, in both groups, maternal complications are higher than in the general population. Both mean gestational age and mean birthweight seems significantly greater for liver transplant versus kidney transplant recipients and the risk of hypertension during pregnancy seems also lower for liver transplant than kidney transplant recipients. Thus, sequelae of chronic kidney diseases have stronger adverse effects on pregnancy, leading to a higher occurrence of adverse neonatal complications. Also, gestation in heart recipients may be complicated and preeclampsia seems to occur more frequently. However, the transplanted heart seems to adapt well to changes caused by pregnancy, such as increased cardiac workload and output, and elevated maternal oxygen consumption. More problematic is pregnancy in lung transplant recipients. Spontaneous pregnancy and healthy childbirth after bone marrow grafting is relatively rare due to irradiation, but, if gestation occurs, no specific problems have been identified. Obstetrical syndromes associated with transplantation reflect the pathology of defective deep placentation, where conversion of uterine spiral arteries remains largely restricted to the decidual segment. The myometrial segments of the uteroplacental arteries have a unique vascular memory and are at great risk to develop obstructive, atherosclerotic lesions. A similar increased risk of complications already existed in pregnancies during the years before transplantation. The effect of immunosuppressive therapy remains speculative. Therefore, the main target for improving the outcome of pregnancy in women at risk is the strict antihypertensive treatment from the earliest stage of pregnancy.

Practical guidelines: lung transplantation in patients with cystic fibrosis

There are no European recommendations on issues specifically related to lung transplantation (LTX) in cystic fibrosis (CF). The main goal of this paper is to provide CF care team members with clinically relevant CF-specific information on all aspects of LTX, highlighting areas of consensus and controversy throughout Europe. Bilateral lung transplantation has been shown to be an important therapeutic option for end-stage CF pulmonary disease. Transplant function and patient survival after transplantation are better than in most other indications for this procedure. Attention though has to be paid to pretransplant morbidity, time for referral, evaluation, indication, and contraindication in children and in adults. This review makes extensive use of specific evidence in the field of lung transplantation in CF patients and addresses all issues of practical importance. The requirements of pre-, peri-, and postoperative management are discussed in detail including bridging to transplant and postoperative complications, immune suppression, chronic allograft dysfunction, infection, and malignancies being the most important. Among the contributors to this guiding information are 19 members of the ECORN-CF project and other experts. The document is endorsed by the European Cystic Fibrosis Society and sponsored by the Christiane Herzog Foundation.

Ciclosporin use during pregnancy

Ciclosporin (cyclosporine) is an immunosuppressive drug first approved for use in organ transplantation to prevent rejection. Ciclosporin is also known to be used for the treatment of psoriasis, rheumatoid arthritis, systemic lupus erythematosus and inflammatory bowel disease, among other indications. While it is recommended that all medications that are not absolutely necessary should be avoided during pregnancy, this may not be an option for many women whose quality of life is significantly impacted without treatment, or for those who must continue immunosuppressive therapy to avoid organ rejection. The purpose of this review is to provide a comprehensive report from the literature of ciclosporin exposure during pregnancy. PubMed, MEDLINE and the Cochrane Database of Systematic Reviews were searched for English-language articles published from 1970 to 2012 that included reports of pregnant women treated at any time during pregnancy with ciclosporin. On an initial search, it was evident that much of the available information is limited to pregnancy after transplant, which suggests that ciclosporin use during pregnancy appears to be associated with premature delivery and low birthweight infants. Comorbidities such as hypertension, pre-eclampsia and gestational diabetes mellitus are also reported at higher incidences than the general population. Medical literature concerning women with autoimmune disorders exposed to ciclosporin during pregnancy are currently limited to case reports and registry data, and, as such, it is difficult to determine if any risks associated with ciclosporin therapy during pregnancy are due to exposure to the drug alone or to pre-existing maternal comorbidities. The literature suggests that ciclosporin therapy during pregnancy should be carefully considered by the treating physician, but may be a safe alternative for patients with autoimmune disease refractory to conventional treatment. Continued monitoring of this patient population remains a key component to understanding the risk factors associated with ciclosporin exposure during pregnancy.
