Study to Investigate Adrenal Crisis (Six-year Follow-up)

Despite established hormone replacement therapy, patients with chronic adrenal insufficiency are at risk of suffering from life threatening adrenal crisis with a considerable mortality. A former prospective study revealed a frequency of about 8 adrenal crisis/ 100 patient years and a crisis associated mortality of 0.5 per 100 patient years for patients; furthermore, patients with a previous adrenal crisis were at higher risk of crisis. The aim of the current trial was to reevaluate the frequency of adrenal crisis and risk factors by contacting the patients of the initial prospective study (see above) within a six-years follow-up. Patients are contacted by questionnaire and additionally by phone (in case of an adrenal crisis or implausible statements).
