A retrospective single centre audit was conducted on the effects of polycythaemia in trans-male and native male.Polycythaemia is a recognised side effect of testosterone treatment. It could be viewed as a maker of excess testosterone action. We examined whether lipid profiles as a marker of cardiovascular risk differed in a population of polycythaemic transmen (TM) and native males (NM).Forty-six NM and 12 TM were identified to hav...

Background: Cortisol is inactivated to cortisone in the salivary gland by 11β-HSD type 2. Concentrations of cortisone and cortisone in saliva correlate strongly with serum cortisol concentrations (1). Only free, biologically active hormone is measured in saliva, testing is non-invasive and can be performed at home/school, reducing cost and inconvenience to families and NHS resources. We previously reported pilot data from healthy children and young people (CYP) (1). Here we de...

Background: Hypoglycaemia, possibly due to non-physiological hormone replacement, and poor cardiovascular outcomes are described in patients with adrenal insufficiency (AI), particularly in the adult population. In this study, we describe glucose profiles and risk factors for premature cardiovascular disease (CVD) in children with secondary AI (SAI).Methods: Participants underwent continuous glucose monitoring (CGM), for seven days (blinded Dexcom G6 mon...

Background: Increased hair cortisol concentrations are reported in Turner Syndrome (TS) patients compared to healthy controls (HC).(1) Increased cortisol exposure could contribute to cardiovascular, metabolic and bone morbidity in TS. Hair cortisol concentrations give no information about the circadian profile of cortisol, which is important for cardiovascular health. Cortisol is inactivated to cortisone by 11β hydroxysteroid dehydrogenase (11βHSD) type-2 and regener...

Background: Saliva is ideal for measuring free, biologically active hormones. Measurements of salivary androgens may be valuable in diagnosis and monitoring of adrenal disorders, however the diurnal profile and robust reference ranges in healthy children are currently undefined. We report salivary testosterone, androstenedione (A4), 11-ketotestosterone (11-KT), 11-β hydroxyandrostenedione (11β-OHA4) concentrations measured throughout the day in healthy children.<...
