Primary aldosteronism with concurrent primary hyperparathyroidism: clinical case load in a single centre.

OBJECTIVE: Primary aldostero - nism (PA) represents the main cause of en - docrine secondary arterial hypertension in which aldosterone production is inappropriate - ly elevated. Primary hyperparathyroidism (PH - PT) is an endocrine disease characterized by hypercalcemia due to overproduction of parathyroid hormone (PTH). Although these two endocrine pathologies are secondary to hypertension in middle aged population, the occurrence of the PHPT in PA patients has rarely reported in the literature. The aim of the study was to describe some PA patients with concurrent PHPT, referred in a tertiary center of arterial hypertension. PATIENTS: We performed a retrospective study. In particular, the registry of 306 patients with PA seen in our center since 2004 was exam - ined and revealed 8 patients (2.6%) with concur - rent PHPT. CONCLUSIONS: There are several possible ex - planations for the association of these two en - docrine disorders, including the combination was a random finding that PA inheres PHPT or vice versa .
