Cushing’s Syndrome during Pregnancy: Personal Experience and Review of the Literature

Abstract

Cushing's syndrome (CS) occurs rarely during pregnancy. We investigated and treated four patients with pituitary-dependent Cushing's syndrome during pregnancy over a 15-yr period at the National Institutes of Health. Except for preservation of menses before conception, our patients presented with typical clinical features, increased urinary free cortisol, and loss of diurnal variation of cortisol. The diagnosis was facilitated, without complications, by the use of CRH testing and inferior petrosal sinus sampling in three women. Transsphenoidal pituitary surgery achieved remission in three women, but there were two fetal/neonatal deaths. This experience and review of 136 previous reports suggest that: 1) urinary free cortisol in CS patients overlaps the normal pregnant range; 2) ACTH levels are not suppressed in adrenal causes of CS, which may be identified by the 8-mg dexamethasone test; 3) inferior petrosal sinus sampling and transsphenoidal pituitary surgery, the optimal diagnostic test and treatment for nonpregnant patients with pituitary-dependent Cushing's syndrome, can safely facilitate the management of pregnant patients; and 4) surgery may achieve remission during pregnancy, but the prognosis for the fetus remains guarded. It is likely that earlier recognition and treatment would improve outcome. There is a need for development of criteria for interpretation of diagnostic tests and increased consideration of CS in pregnancy.

  • During the second trimester, UFC increases approximately 1.4-fold, and during the third trimester, approximately 1.6-fold.

    “During the second trimester, UFC also increases, leading to an approximately 1.4-fold increase during the second trimester and a 1.6-fold increase during the third trimester.”

  • The biochemical diagnosis of CS during pregnancy can be more challenging because of normal physiologic changes that occur during pregnancy, including activation of the HPA axis.

  • Suppression of serum and plasma cortisol by dexamethasone is blunted during pregnancy, making the DST difficult to interpret.

    “Suppression of serum and plasma cortisol by dexamethasone is blunted during pregnancy; therefore, making the DST difficult to interpret in these patients (3, 90, 92).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
