This is an open-label, non-randomized crossover design feasibility trial comparing oral hydrocortisone treatment with interval bolus delivery (pulsatile) of subcutaneous hydrocortisone via infusion pump in children with congenital adrenal hyperplasia. Eight children, ages 4-18 yrs, will have 24-hr pharmacokinetic and pharmacodynamic profiles of cortisol, 17-hydroxyprogesterone and androstenedione concentrations while on oral hydrocortisone therapy (admission 1), during an initial trial of the subcutaneous hydrocortisone pump (admission 2), and after 6 weeks of subcutaneous hydrocortisone pump treatment (admission 3). An integrated pharmacokinetic and pharmacodynamic model will be used to determine cortisol, 17-hydroxyprogesterone and androstenedione parameters to compare the duration of time subjects have these concentrations outside acceptable ranges.
