ACTA ENDOCRINOLOGICA (BUC)

Primary Hyperaldosteronism is one of the causes of secondary hypertension. Primary Hyperaldosteronism is characterised by an increase in the production of aldosterone and the inhibition of the secretion of renin. We described here a case with rhabdomyolysis and severe hypokalemia as a cause of primary hyperaldosteronism. The creatine kinase, aldosterone were very high. Cortisol values and midnight salivary cortisol values were within normal range. The patient had been under treatment for high blood pressure for more than six years, with ARBs and calcium channel blockers. During this time the potassium values measured frequently every year were below normal range, but primary hyperaldosteronism was not suspected.
