Normal Delivery Following an Uneventful Pregnancy in a Japanese Acromegalic Patient after Discontinuation of Octreotide Long Acting Release Formulation at an Early Phase of Pregnancy

We report a 35-year-old woman with active acromegaly despite pituitary surgery and irradiation who received continuous octreotide LAR treatment for the control of GH excess until discovery of her pregnancy. The patient delivered a healthy boy following an uneventful pregnancy after discontinuing octreotide LAR as soon as possible at the early phase of pregnancy. Despite a substantial maternal-fetal transfer of octreotide, postnatal development was normal at 3 years of age. In almost all previously described cases, octreotide was discontinued after pregnancy was confirmed. No side-effects of mother or fetus have been reported. Octreotide treatment in pregnancy seems to be feasible and safe. Due to the still-limited number of reported cases treated with octreotide LAR, the potential benefits of octreotide LAR treatment should be weighed carefully against its possible risks.
