    Abstract:
    CONTEXT: Current guidelines on how to divide the daily cortisol substitution dose in patients with primary adrenal insufficiency (PAI) are controversial and mainly based on empirical data. OBJECTIVE: To assess how an equal dose of hydrocortisone (HC) given either four times daily or twice daily influence diurnal profiles of cortisol and ACTH, patient preferences and health-related quality of life (HRQoL). DESIGN: Double blind, crossover. METHODS: Fifteen patients with PAI (six women) were included. Capsules of HC or placebo were given at 07:00, 12:00, 16:00 and 22:00 h in 4-week treatment periods: either one period with four doses (10 + 10 + 5 + 5 mg) or one period with two doses (20 + 0 + 10 + 0 mg). Diurnal profiles of cortisol and ACTH were collected, and area under the curve (AUC) was calculated. Questionnaires were used to evaluate patient preferences and HRQoL. RESULTS: The four-dose regimen gave a higher serum cortisol before tablet intake in the morning (P = 0·027) and a higher 24-h cortisol(AUC) (P < 0·0001) compared with the two-dose period. In contrast, a lower median plasma ACTH in the morning before tablet intake (P = 0·003) and a lower 24-h ln(ACTH(AUC) ) were found during the four-dose period. The patients preferred the four-dose regimen (P = 0·03), and the HRQoL scores tended to be higher (high score indicates better HRQoL) for the four-dose period. In summary, a four-dose regimen gives increased availability of cortisol and an enhanced effect with a less elevated ACTH in the morning in comparison with a two-dose regimen but the effect on HRQoL remains inconclusive.
