METHOD FOR DIAGNOSING OBLITERATED FORMS OF CONGENITAL SUPRARENAL GLAND CORTEX HYPERPLASIA Russian patent published in 2005 - IPC

FIELD: medicine.

SUBSTANCE: method involves applying high effectiveness liquid chromatography for determining cortisol, cortisone 11-deoxycorticosterone, 11-deoxycortisone concentration in blood and free cortisol and free cortisone excretion with urine. Ratios of F/E and FF/FE are calculated, where F is the cortisol level in blood; E is the cortisone level in blood; FF is the free cortisol excretion with urine and FE is the free cortisone excretion with urine. The cortisol level in blood not exceeding norm and at least two of three signs: F/E ratio reduction by 25% and more, FF/FE ratio reduction by 25% and more, free cortisol excretion with urine being equal to 25% and more, obliterated forms of congenital suprarenal gland cortex hyperplasia is diagnosed. Corticosterone level in blood growing by 50% and higher, 21-hydroxylase defect is considered to be the case. 11-deoxycorticosterone and/or 11-deoxycortisone concentration in blood being et or greater than 50%, 11β-hydroxylase defect is considered to be the case.

EFFECT: high accuracy of early stage diagnosis.
