Design outcomes

Primary

MeasureTime frame
Main Objective: To compare the hormonal responses of patients with Addison's disease and congenital adrenal hyperplasia on standard oral and pulsatile subcutaneous hydrocortisone replacement therapy.;Secondary Objective: To compare the metabolic, psychological (cognitive and emotional processing) and quality of life measures of patients with Addison's disease and congenital adrenal hyperplasia on standard oral replacement and pulsatile subcutaneous hydrocortisone replacement therapy.;Primary end point(s): The primary outcome measure is to achieve a physiological cortisol circadian and ultradian rhythms with adequate suppression of ACTH on waking in both AD and CAH patients, and of morning 17-OHP levels in CAH.;Timepoint(s) of evaluation of this end point: Baseline and 6 week blood samples for ACTH, cortisol and 17-OHP/androstenedione (CAH only) 24 hour blood samples for ACTH, cortisol and cortisone (10 minute all patients), POMC (hourly all patients), 17-OHP (1-3 hourly CAH only) profiles. This is an optional study during week 6-7.

Secondary

MeasureTime frame
Secondary end point(s): The secondary objective is to be able to demonstrate this intervention improves metabolic parameters, health related quality of life, fatigue, general well being, working memory and emotional and cognitive processing;Timepoint(s) of evaluation of this end point: In each study arm Metabolic parameters - metabolic blood profile (baseline and week 6), weekly body composition, BP and weight. Standardized patient questionnaires for subjective assessment of well-being (main outcome in comparison to baseline) Beck’s inventory of depression scale (baseline only) SF36, Chalder Fatigue Scale, ICFS and AdQuoL (at week -1, 1 and 6) PANAS (at week -1, 1 and 6 ) PSQI (at week -1, 1 and 6 ) and LSEQ (weekly) Ecological Momentary assessment (main outcome, to be collected daily ) Laboratory based psychological tests and fMRI scan (main outcome, week 6) N-Back task (main outcome in comparison to baseline, week 1 and 6) Actigraphy and sleep diary (main outcome, in comparison to baseline and transition of treatment)
