Characterization of persistent and recurrent Cushing’s disease

Pituitary, 09/25/2013  Review Article

Sundaram NK et al. – A case of possible recurrent Cushing’s disease (CD) is presented and data on current definitions of CD remission, persistence, and recurrence are reviewed.

The number and degree of abnormal test results needed to define recurrence, and the determination of which biochemical test has more significance when there are discrepancies between markers is inconsistent among studies. Further inquiry is warranted to examine if patients in apparent CD remission who have subtle hypothalamic pituitary adrenal (HPA) axis abnormalities represent distinctive remission subtypes versus mild or early recurrence.

Additional investigation could also explore the degree to which these HPA axis abnormalities, such as alterations in cortisol circadian rhythm or partial resistance to dexamethasone, are associated with persistence of CD morbidities, including neuropsychiatric impairments, alterations in body composition, and cardiovascular risk.
