E.5 End points |
E.5.1 | 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. |
|
E.5.1.1 | 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. |
|
E.5.2 | 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 |
|
E.5.2.1 | 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) |
