Introduction: Impairment of the hypothalamic–pituitary–adrenal (HPA) axis has been reported widely in children treated with inhaled corticosteroids (ICS). The integrity of HPA axis has been assessed using low (500 ng/1.73 m2 body surface area) and standard (250 mg) dose short synacthen tests (SST). Serum cortisol is measured at 0, 15, 20, 25, 30 and 35 min intervals in the low dose SST (LDSST) and at 0, 30 and 60 min in the standard dose SST (SDSST). The L...

Background: Low thyroid hormone concentrations in the first few weeks of life in preterm infants may be linked with poor neurodevelopment. We conducted a multi-centred randomised controlled trial of thyroxine (T4) supplementation in babies born under 28-weeks’ gestation (TIPIT study). A post hoc subgroup analysis was undertaken to examine brain growth and development.Methods: Seventy-eight infants received T4 supplementation an...
