Background
Pregnancy in acromegaly is uncommon and still in debate for fear of tumor progression or potential threat to both mother and fetus’s health. Besides, the data for pregnancy complications in uncontrolled acromegaly is limited. Thus, the objective of this study was to summarize pregnancy safety and disease courses after pregnancy in acromegalic patients and review their clinical characteristics based on disease activity in the literature.
Methods
An evaluation of eight acromegalic women from Peking Union Medical College Hospital (PUMCH) with 11 pregnancies was conducted. We also summarized a literature review of 82 disease-active pregnancies and 63 disease-controlled pregnancies with acromegaly. A second analysis was conducted to compare pregnancy courses and outcomes in different disease activities.
Results
Before pregnancy, all patients had macroadenomas and underwent pituitary surgery. Pregnancy occurred at a median of 6 years (4–10) after the diagnosis of acromegaly. Assisted reproductive therapy was needed in 42.9% of participants. No cases had a premature birth or congenital malformations. Biochemical control was achieved in 50% of females before pregnancy and 75% at the last follow-up after delivery. Data analysis showed no differences in the prevalence of gestational diabetes mellitus (GDM) or pregnancy-induced hypertension (PIH) between acromegaly-active or acromegaly-controlled groups. The GDM prevalence in patients diagnosed during pregnancy (33.3%) was higher than that in patients diagnosed before pregnancy (4.8%) (p = 0.001).
Conclusion
Pregnancy without biochemical control in acromegaly and receiving medical treatment during pregnancy are not rare and generally safe for the fetus. There could be a higher prevalence of PIH in acromegalic pregnancies. The treatment of acromegaly and related complications can be managed with regular follow-up after pregnancy.
