Pregnancy after liver transplantation: a case series and review of the literature

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

BACKGROUND

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

CASE PRESENTATION

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

CONCLUSION

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

Type of donor liver transplant does not affect pregnancy outcomes-a systematic review and meta-analysis

Liver transplant (LT) has become increasingly common among reproductive-aged women. The effect of the type of liver donor, either a living donor LT (LDLT) or a deceased donor LT, on pregnancy outcomes is unknown. As such, we aim to review the available literature and assess obstetric, pregnancy, or delivery outcomes in LDLT. We conducted a comprehensive literature review of MEDLINE, EMBASE, Cochrane, and Scopus databases. Random-effect meta-regression assessed the association between the percentage of women who underwent LDLT (independent variable) and the proportion of outcomes. Meta-regression results were expressed as a regression coefficient, which transforms the proportion of outcomes of interest associated with a 1% increase in the percentage of LDLT patients. A value of 0 denotes no relationship between the outcomes and LDLT. A total of 6 articles (438 patients) were included, with a total of 806 pregnancies. Eighty-eight (20.09%) patients underwent LDLT. None of the studies segregated the data based on the type of donor LT. The median time from LT to pregnancy was 4.86 (4.62-5.03) years. Twelve (1.5%) stillbirths were reported. LDLT was statistically significantly associated with a higher rate of stillbirths (coefficient 0.002, p < 0.001; I 2 0%). The type of donor LT was not associated with an increased risk of other obstetric, pregnancy, or delivery complications. This is the first meta-analysis to evaluate the effect of the type of donor LT on pregnancy outcomes. This study highlights the lack of robust literature addressing this important topic. The results suggest that pregnancy outcomes after LDLT and deceased donor LT are comparable. Despite LDLT being statistically significantly associated with a higher rate of stillbirths, the association is weak and is unlikely to be clinically significant.

Surgical management of colon cancer in ulcerative colitis patients with orthotopic liver transplant for primary sclerosing cholangitis. A systematic review

INTRODUCTION

Colon cancer in ulcerative colitis patients with liver transplant (UCCOLT) due to primary sclerosing cholangitis carries significant treatment challenges. Aim of this literature search is to review management strategies and provide a framework to facilitate the decisional process in this clinical setting.

METHODS

PRISMA-compliant systematic search was followed by critical expert commentary of the results and development of a surgical management algorithm. Endpoints included surgical management, operative strategies, functional and survival outcomes. Technical and strategics aspects with particular regard to the choice of reconstruction were evaluated to tentatively develop an integrated algorithm.

RESULTS

Ten studies reporting treatment of 20 UCCOLT patients were identified after screening. Nine patients underwent proctocolectomy and end-ileostomy (PC) and eleven had restorative ileal pouch-anal anastomosis (IPAA). Reported results for perioperative outcomes, oncological outcomes, and graft loss were comparable for both procedures. There were no reports of subtotal colectomies and ileo-rectal anastomosis (IRA).

CONCLUSIONS

Literature in the field is scarce and decision-making is particularly complex. PC and IPAA have been reported with good results. Nevertheless, IRA may also be considered in UCCOLT patients in selected cases, reducing the risks of sepsis, OLT and pouch failure; furthermore, in young patients, it has the advantage of preserving fertility or sexual function. The proposed treatment algorithm may represent a valuable support in guiding surgical strategy.

Evaluation of the Effects of Immunosuppressive Drugs Following Liver Transplantation on Pregnancy Outcomes: A Retrospective Study

BACKGROUND

Liver transplantations can be safely performed in women of reproductive age. Women with chronic liver disease may have infertility for various reasons, although fertility returns after recovering >90% of sexual disorders following liver transplantation. The present study examined the effects of immunosuppressive drugs used by women of reproductive age undergoing liver transplantation in our clinic on pregnancy and pregnancy outcomes and evaluated mortality and morbidity in this patient population.

METHODS

Among the patients undergoing liver transplantation in our clinic between 1997 and 2020, those conceiving after liver transplantation were evaluated in the present study. Demographic data on maternal and newborn health, as well as mortality and morbidity, were recorded. Maternal transplant indications, graft type, the interval between transplantation and pregnancy, maternal age at pregnancy and the number of pregnancies, the number of living children, complications, delivery mode, immunosuppressive drugs, and blood levels were investigated.

RESULTS

A total of 615 liver transplantations (353 from a living donor, 262 from a cadaveric donor) were performed in our clinic. Furthermore, 33 pregnancies occurred in 22 women following transplantation (17 living donor liver transplantations, 5 deceased donor liver transplantations), and the data of these patients were recorded. Tacrolimus and mycophenolate mofetil were used as immunosuppressive therapy.

CONCLUSIONS

Liver transplantations can be safely performed in women of reproductive age if indicated, and these patients can be safely followed up throughout the pregnancy and during labor by a multidisciplinary team.

Domino liver transplant from a donor with maple syrup urine disease into a recipient with phenylketonuria

Classical phenylketonuria (PKU) presents a unique challenge for women of child-bearing age. In the context of pregnancy, poorly controlled hyperphenylalaninemia can result in a devastating constellation of outcomes for the baby referred to as the maternal PKU Syndrome. We present the case of a woman with classical PKU unable to maintain a restricted diet and refractory to pharmacological therapies. She elected to undergo a domino liver transplant, receiving an organ from a donor with classical branched chain ketoacid dehydrogenase deficiency (maple syrup urine disease). Plasma phenylalanine concentrations normalized within a few days after transplant and remained so on an unrestricted diet during the first year of follow-up. The patient reports subjective improvements in mood, energy level, and overall quality of life. In the appropriate clinical setting, liver transplant should be considered to provide metabolic stability for PKU patients, particularly women of childbearing age.

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.

Immunologic and Infectious Concerns in Uterus Transplantation

Pharmacologic immunosuppression is required for the success of uterus transplantation but can provoke several complications for the transplant recipient. In this review, we discuss the immunologic complications that can occur in the uterus transplant recipient. First, we provide the latest update on immunosuppression regimens used by programs throughout the world. Next, we discuss the prevalence, mechanisms, treatment, and outcome of rejection in uterus transplant recipients. Finally, we discuss infectious complications of varying severity alongside their treatment and impact.

A Long-term Evaluation of Treatment Results of Pregnant Patients Following a Liver Transplant

INTRODUCTION

Transplantation is not only the best method for treating end-stage failure of many organs but also the way to improve the quality of life of patients. For women of childbearing age, an organ transplant often brings a restoration of regular reproductive functions, which means, among other things, the possibility of having biological offspring.

OBJECTIVES

The aim of the study was to analyze the medical records and assess the impact of a liver transplant on the course of pregnancy and labor.

MATERIALS AND METHODS

The research was carried out from March to May 2019 in the Nephrology and Transplant Clinic Medical University of Warsaw. The study group consisted of 19 women after liver transplantation. Medical records were analyzed, and laboratory test results routinely performed on patients were also used for the study.

RESULTS

The mean age of conception of the patients following transplantation was 30 ± 4 years old. In the analyzed period, 6 patients gave birth to 2 children each, and 8 patients to 1 child each. Only 3 patients experienced premature birth. Twelve patients gave birth by caesarean delivery. Fourteen patients took tacrolimus.

CONCLUSIONS

Pregnancy is possible in patients following a liver transplant and does not appear to have a damaging effect on liver functionality. There is an increased risk of pre-eclampsia, intensified hypertension, and premature birth among patients following a transplant, which is why it is essential for these patients to remain under the care of a specialistic therapeutic team.
