Summary

The analysis of 24-h excretion profiles of urinary steroids in 18 patients suffering from Cushing's syndrome or adrenocortical tumors revealed typical patterns when compared to 37 healthy control persons, 24 patients with obesity, and 6 patients with hirsutism. The validation of eight criteria — increased excretion of free cortisol, 6β-hydroxycortisol, 20α-dihydrocortisol, 11β-hydroxyandrosterone, and 3β-hydroxy-5-en steroids, decreased ratio of tetrahydrocortisone (THE) to tetrahydrocortisol (THF), and increased ratios of THF to allotetrahydrocortisol (a-THF) and metabolites of androgens (AM) to metabolites of cortisol (CM) — afforded reliable detection of disorders in steroid biosynthesis. The analysis of urinary steroid profiles can therefore be recommended as a screening procedure in patients with clinical symptoms of disorders in steroid production and/or metabolism.
