High-risk pregnancy management in women with hypopituitarism

K Kübler et al. J Perinatol. 2009 Feb.

Abstract

Pregnancy after complete loss of pituitary function is uncommon. However, advances in fertility treatment have led to increased pregnancy rates in hypopituitary women. We hereby present a literature review of pregnancies affected by hypopituitarism, including a comparison with published controls; further, we add one case report of severe hypopituitarism where third-trimester oxytocin supplementation was performed. As only limited information is available on management and outcome, our purpose was to determine obstetric complications associated with deficiency of pituitary hormones. The analysis of 31 pregnancies in 27 women revealed that hypopituitary women are at increased risk: postpartum hemorrhage occurred in 8.7%, transverse lie in 16%; 42.4% of the newborns were small for gestational age. These findings are supposedly the result of uterine dysfunction caused by hormone deficiency. Oxytocin supplementation was performed with the aim to establish physiologic conditions and to prevent postpartum uterine inertia. In this case substitution may have contributed to correct fetal presentation but did not prevent postpartum hemorrhage. Further investigations into both oxytocin-dependent and -independent mechanisms regulating uterine contractions and contractility are necessary to develop strategies for prevention of uterine inertia in oxytocin-deficient pregnancies.
