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.
