Steroid profiling characteristics in pediatrc adrenal diseases

Probl Endokrinol (Mosk). 2022 Nov 3;68(6):110-120. doi: 10.14341/probl13166.


BACKGROUND: Adrenocortical adenomas are often followed with steroid hormones hyperproduction, and therefore determination of their concentration plays an important role in the differential diagnosis of adrenal diseases. Steroid profiling by tandem mass spectrometry is one of the main diagnostic methods in steroidogenesis characterization. Currently plasma and urinary steroid profiling is of particular interest in differential diagnosis and subtyping patients with adrenocortical adenomas.

AIM: Steroid profiling of pediatric patients with adrenal diseases (incidentalomas, ACTH-secreting pituitary adenoma, ACTH-independent Cushing syndrome, premature adrenarche).

MATERIALS AND METHODS: We conducted a retrospective analysis of steroid profile of 41 pediatric patients with adrenal diseases who were observed between 2005 and 2020 at the Endocrinology Research Centre.

RESULTS: All patients were divided into groups due to diagnosis: with ACTH-secreting pituitary adenoma [n=7], ACTH-independent Cushing syndrome (autonomous cortisol secretion by an adrenal adenoma) [n=4], with incidentaloma [n=7] and premature adrenarche [n=23]. In group of patients with ACTH-independent Cushing syndrome identified statistically significant higher levels of 11-deoxycortisol (р=0, 0035) and significant lower levels of 17-hydroxypregnenolone (р=0, 0026) and DHEA (р=0, 0047) compared to other groups. Statistically significant differences in steroid profiles between other groups were not identified.

CONCLUSION: Results of our study steroid profiling can be used as additional differential diagnosis method in patients with adrenocortical adenomas with or without hormonal hyperproduction (ACTH-independent Cushing syndrome and incidentaloma). Further studies are needed to identify steroid markers for subtyping pediatric adrenal diseases.
