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.

Pregnancy Outcomes Following Cardiac Transplantation.

OBJECTIVE: This study sought to report pregnancy outcomes in women following cardiac transplantation. METHODS: This was a descriptive retrospective cohort study of women with pregnancies following cardiac transplantation managed at two large tertiary centres in Canada and Belgium between 2001 and 2017. RESULTS: Sixteen women had 17 singleton pregnancies following cardiac transplantation. The mean maternal age was 28 ± 5.8, and the transplant-to-pregnancy interval was 7.3 ± 4.0 years. There were two first trimester terminations, one for teratogenicity concerns and the other because of a maternal cardiac condition. There was one spontaneous miscarriage. All women had normal left ventricular function at the start of pregnancy. Graft rejection occurred in two women. Other maternal complications included anemia requiring blood transfusion (n = 5), renal failure or deterioration (n = 4), preeclampsia (n = 2), and urine infections (n = 2). The mean GA at delivery was 35 ± 3.5 weeks. Six infants were born preterm, and two were small-for-gestational-age. Fetal anomalies were identified in two pregnancies. Women were followed after pregnancy for a median of 5.6 years (range, 10 months to 15 years). Although there were no deaths during pregnancy, two women died at 10 and 18 months after delivery. CONCLUSION: With appropriate multidisciplinary care, women with cardiac transplants can have successful pregnancies. Although rates of fetal loss are low, these women continue to be at risk for graft rejection, preterm birth, other pregnancy-related complications, and cardiovascular death.
