The urinary steroids excreted by three newborn infants with 21-hydroxylase deficiency and by 15 healthy newborns aged two days have been compared after analysis by gas liquid chromatography (GLC). The identity of each steroid was carefully checked by gas chromatography/mass spectroscopy (GC-MS). The enzyme deficiency leads to the elevated excretion of urinary precursor metabolites, mainly 3alpha,17alpha,20alpha-trihydroxy-5beta-pregnan, 3alpha,17alpha,20alpha-trihydroxy-5beta-pregnan-11-one and 3alpha,17alpha-dihydroxy-5beta-pregnan-20-one. In the search for a quick and firm confirmation of suspected 21-hydroxylase deficiency in a newborn baby by means of a GLC-profile of urinary steroids, most attention has up to now been paid to 3alpha,17alpha,20alpha-trihydroxy-5beta-pregnan. However, 3alpha,17alpha-dihydroxy-5beta-pregnan-20-one is a better indicator, as it enables one to confirm the existence of this disease soon after birth directly from the GLC-profile without further analyses by GC-MS.
