Introduction: Primary hyperparathyroidism (PHP) has been postulated to be a cause of primary hyperaldosteronism (PHA). In fact, PTH receptors have been detected in aldosteronoma tissue. Hyperaldosteronism can also induce elevation of PTH levels, as increased circulating volume increases calciuria, with secondary elevation of PTH levels as serum calcium levels rise. We studied the prevalence of PHP in a group of patients diagnosed with PHA either following or simultaneously wit...

Introduction: Primary hyperaldosteronism (PH) is characterized by autonomous adrenal aldosterone (A) hypersecretion. Unilateral adrenalectomy is the treatment of choice, when adrenal vein sampling (AVS) indicates lateralization of A secretion. To assure that each adrenal vein (AV) has been correctly sampled, cortisol levels in each adrenal vein must be higher than in the inferior vena cava. The adrenal gland cortisol/vena cava cortisol ratio is referred to as the selectivity i...
