<p></p><p>Introduction: Monitoring
of hormonal control represents a key part in the management of congenital
adrenal hyperplasia (CAH). It remains suboptimal and relies on frequent blood
tests, which are traumatising in children and young persons. We aimed to establish
a non-invasive test for monitoring of adrenal-specific androgens in CAH.</p><p> Objective: To establish the correlation between plasma and salivary androgens
in children with CAH. </p><p>Patients and Methods: Patients (n=78) and matched
controls (n=62) were recruited in a multicentre prospective study of children
with CAH across the United Kingdom. Using liquid chromatography tandem mass
spectrometry, we measured plasma and salivary concentrations for five steroid
hormones: 17-hydroxyprogesterone, androstenedione, testosterone,
11-hydroxyandrostenedione and 11-ketotestosterone and established the
correlation between plasma and salivary steroids to assess their usefulness in
clinical practice. </p><p>Results: Plasma and salivary steroid concentrations show a
good correlation, with androstenedione and 11-ketotestosterone. In addition, a
high correlation was found in patients with CAH when analysing subgroups based
on gender and age. Clear differences can be found for all plasma and salivary
steroids between patients and controls. </p><p>Conclusions: We have established the
close correlation between plasma and salivary concentrations of steroid
hormones assessed for therapy control CAH patients. Importantly, the best
correlations were found for the adrenal-derived 11oxygenatedC19 androgen
11-ketotestosterone as well as 17-hydroxyprogesterone and androstenedione,
which are widely used for CAH monitoring. Thus, we believe that this novel and
improved combination of salivary steroid hormones can serve as non-invasive
monitoring tool in CAH providing a significant amount of additional information
and will ultimately improve management and outcomes in CAH.</p><p></p><p>The following files are
