PTH and primary aldosteronism: However, compared to men without likely primary aldosteronism, those with likely primary aldosteronism had lower vitamin D. For the group of men meeting the definition for possible primary aldosteronism, there was a trend towards elevated parathyroid hormone and lower vitamin D. Similar observations with elevated parathyroid hormone and reduced vitamin D for individuals with primary aldosteronism have also been reported in other studies [6, 9, 10].
