Abstract/OtherAbstract:
Normotensive primary hyperaldosteronism is exceedingly rare. We report two new cases of this syndrome in two middle-aged women, one of Asian origin. The presenting signs were tetany in one case and an adrenal mass in the other. Neither patient had hypertension, despite repeated measurements with a manual armlet. A typical biological profile of primary hyperaldosteronism was demonstrated in both patients, including hypokalemia with inappropriate kaliuresis, elevated resting plasma aldosterone, and undetectable plasma renin activity. The circadian rhythm of blood pressure was studied by ambulatory monitoring pre- and post-operatively. It confirmed the lack of hypertension, but the circadian rhythm of blood pressure was lost before surgery in one patient. Surgical removal of the histologically typical aldosterone-producing adenomas normalized the kalemia. The main finding in these two patients was spontaneously low blood pressure in the post-operative period. This suggests that excess aldosterone induced relative hypertension in these patients whose blood pressure was spontaneously very low. Genetic screening for dexamethasone-sensitive hyperaldosteronism was negative in both patients.
