[Adrenocortical insufficiency in renal amyloidosis].
Renal involvement in amyloidosis leads to chronic renal failure. Prognosis is poor. Although amyloid deposits are frequent in adrenal glands, symptomatic adrenal dysfunction is uncommon. We report the case of a 63-year-old man with chronic renal failure (serum creatinine: 202 micromol/L) subsequent to amyloidosis who was referred to our unit for vomiting, dehydration despite a persistent nephrotic syndrome, acidosis, hyponatremia (121 mmol/l) and hyperkaliemia (7.1 mmol/l). A synacthen test was performed and disclosed adrenal insufficiency. Despite the initiation of substitution therapy, the patient died one month later from Addisonian crisis. Features of adrenal insufficiency may be masked by those of chronic renal failure, emphasizing the importance of adrenal explorations in patients with chronic renal failure due to amyloidosis.
