Physiologic Interactions Between the Adrenal- and the Parathyroid Glands


Brief description of study

To investigate possible physiologic interactions between the adrenal- and the parathyroid glands in patients with secondary hyperparathyroidism.

Detailed Study Description

In primary hyperparathyroidism, chronic-elevated PTH levels seem to stimulate the renin-angiotensin-aldosterone system (RAAS) which may explain the increased risk of cardiovascular disease. In addition to increased PTH levels, vitamin D has been shown to inhibit the RAAS. However, a possible physiologic interaction needs further investigation.

The purpose of the study is to investigate changes in the RAAS in otherwise healthy postmenopausal women with secondary hyperparathyroidism due to vitamin D deficiency when p-PTH is normalized.

Furthermore, we will evaluate whether an angiotensin 2 receptor blocker can lower PTH in patients with secondary hyperparathyroidism.

Clinical Study Identifier: NCT02572960
