[Salivary steroid profile investigation by high performance liquid chromatography-tandem mass spectrometry in children with congenital adrenal hyperplasia]
Tiulpakov et al.
The finding, in our words
Salivary concentrations of 17OH-progesterone, androstenedione, dehydroepiandrosterone, testosterone and progesterone showed strong positive correlations with serum in both prepubertal and pubertal children with congenital adrenal hyperplasia, supporting saliva as a minimally invasive alternative to venipuncture for diagnosis and therapy monitoring.
A paraphrase to the Library’s standard, never the abstract. The source is one link away and is always the authority.
During ACTH stimulation, salivary cortisol correlated only weakly with serum and gave modest accuracy: saliva does not reliably replace serum cortisol for adrenal insufficiency. A concrete limit.
A liquid chromatography-tandem mass spectrometry method was successfully validated for measuring androstenedione, 17α-hydroxyprogesterone, and 11-ketotestosterone in dried blood samples collected via volumetric absorptive microsampling. The dried samples remained stable at room temperature for up to a week and after postal transit, and plasma concentrations could be reliably estimated from the microsamples when adjusting for haematocrit.
This study used home self-collected saliva samples to successfully monitor cytokines and cortisol in mothers and infants, finding that a community singing intervention significantly reduced salivary interleukin-6 levels in mothers with postnatal depression.

Self-collected salivary progesterone and the ratio of estradiol to progesterone showed strong agreement with serum levels, supporting the use of saliva as a noninvasive matrix for monitoring the menstrual cycle.

This study found that salivary 11-dehydrodexamethasone correlates strongly with serum dexamethasone, unlike salivary dexamethasone which shows poor agreement. This validation suggests patients could self-collect saliva samples at home to verify dexamethasone absorption for the overnight suppression test.
