Objective: Adrenal crisis (AC) is a life-threatening complication of adrenal insufficiency (AI), which according to retrospective data represents a significant clinical complication. Here we aimed to prospectively assess incidence of AC and mortality associated with AC in patients with chronic AI. Methods: Atotal of 423 patients with AI (primary AI, n = 221; secondary AI, n = 202) were prospectively followed up for 2 years. Baseline assessment included a general questionnaire and detailed written instructions on glucocorticoid dose adaptation during stress. Patients received follow-up questionnaires every 6 months and were contacted by phone in case of reported adrenal crisis. Results: A total of 423 data sets were available for baseline analysis, and 364 patients (86%) completed the whole study. Sixy-fourAC in 767.5 patient-years were documented (8.3 crises per 100 patient-years). Precipitating causes were mainly gastrointestinal infection, fever, and emotional stress (20%, respectively) but also other stressful events (eg, major pain, surgery, strenuous physical activity, heat, pregnancy) or unexplained sudden onset of AC (7%) were documented. Patients with a previous AC were at higher risk of crisis (odds ratio 2.85, 95% confidence interval 1.5-5.5, P < .01). However, no further risk factors could be identified. Ten patients died during follow-up; in four cases death was associated with AC (0.5 AC related deaths per 100 patient-years). Conclusion: Even in educated patients with chronic adrenal insufficiency, AC occurs in a substantial proportion of cases. Furthermore, we identified AC-associated mortality in approxoimately 6% of AC. Our findings further emphasize the need for improved management of AC in patients with chronic AI.
