BACKGROUND: Even in the setting of chronic glucocorticoid substitution in hypocortisolaemic patients, severe side-effects will eventually occur when the dosage is inappropriately high. This study evaluates the effect of usual hydrocortisone substitution dosages on the well-being of the patients and on parameters of the bone metabolism to establish an optimum substitution dosage. DESIGN: In a double blind study nine patients with secondary hypocortisolism, being divided in three groups of three, received different doages of hydrocortisone (15, 20, 30 mg per day). Well-being was assessed using three different, validated questionnaires. Markers of bone metabolism were measured in blood and urine. RESULTS: The patients' quality of life was not impaired even at low dosages of hydrocortisone (15 or 20 mg per day). Of all laboratory parameters only osteocalcin significantly changed, decreasing at higher dosages. CONCLUSIONS: Our study shows that a risk of bone loss may be avoided with a substitution dosage of 20 mg or even 15 mg hydrocortisone per day, without influencing the well-being of the patient.
