Background: Acromegaly is well known to induce hypertrophic and hyperplastic changes in various organs and is commonly accompanied by arterial hypertension. In our study, we assess the adrenal morphology and function in a series of patients with acromegaly and possible associations with the activity of the disease and arterial hypertension.
Materials And Methods: Sixty patients with acromegaly, admitted to two endocrinology departments in the time period 2005-2010, were studied prospectively.
Background: Previous studies based on standard endocrine testing have generally shown a low prevalence of primary aldosteronism, a form of autonomous aldosterone secretion (AAS), in hypertensive individuals. The purpose of this case-control study was to evaluate whether use of appropriately defined controls and combined testing reveal previously undetected AAS in hypertensives.
Materials And Methods: We investigated aldosterone secretion in 180 hypertensives with (n = 44) and without (n = 136) adrenal adenomas on computerized tomography (CT) and 72 matched nonhypertensive individuals with normal adrenal CT.
Objectives: Previous studies based on standard endocrine testing have shown a variable incidence of autonomous cortisol secretion (ACS) or autonomous aldosterone secretion (AAS) in patients with single adrenal adenomas (SAA). We tested whether the use of appropriate controls and modification of standard testing, aiming at eliminating interference from endogenous ACTH, reveals previously undetected subtle ACS and AAS by SAA.
Design: Case control study.
