Adrenal insufficiency attributable to adrenal hemorrhage: long-term follow-up with reference to glucocorticoid and mineralocorticoid function and replacement.

OBJECTIVE: To describe the long-term follow-up of acute adrenal insufficiency attributable to bilateral adrenal hemorrhage.

METHODS: We performed a retrospective review of medical records of four patients who underwent follow-up for 6(1/2) to 19 years.

RESULTS: Despite published reports of more than 500 patients with bilateral massive adrenal hemorrhage through 2001, no long-term data assessing the continuing requirements for glucocorticoid and mineralocorticoid replacement are available. After follow-up of four patients with acute bilateral adrenal hemorrhage and glucocorticoid insufficiency for 6(1/2) to 19 years, we document the absence of need for long-term mineralocorticoid replacement on the basis of no occurrence of postural hypotension, normal electrolytes, normal baseline or cosyntropin-stimulated serum aldosterone levels, and generally, though not invariably, normal plasma renin activity levels. We further document the improvement in either or both baseline and cosyntropin-stimulated serum cortisol levels in three of the four patients and the ability of one patient to function normally without cortisol replacement for 4 years. Adrenal histologic findings in this last-mentioned patient revealed previously undescribed changes consistent with regeneration and myelolipoma. Finally, we confirm bilateral atrophic adrenal glands by computed tomography 5(1/2) to 11(1/2) years after bilateral adrenal hemorrhage in three of the four patients.

CONCLUSION: Long-term follow-up of patients with acute adrenal insufficiency attributable to adrenal hemorrhage demonstrates, for the first time, absence of need for prolonged mineralocorticoid replacement and some improvement in endogenous glucocorticoid function in at least some of these patients.
