Prevalence and Clinical Manifestations of Primary Aldosteronism Encountered in Primary Care Practice.

Background: Despite being widely recognized as the most common form of secondary hypertension, among the general hypertensive population the true prevalence of primary aldosteronism (PA) and its main subtypes, aldosterone-producing adenoma (APA) and bilateral adrenal hyperplasia (BAH), remains a matter of debate.

Objectives: This study sought to determine the prevalence and clinical phenotype of PA in a large cohort of unselected patients with hypertension, consecutively referred to our hypertension unit, by 19 general practitioners from Torino, Italy.

Methods: Following withdrawal from all interfering medications, patients were screened for PA using the ratio of serum aldosterone to plasma renin activity.

Long-term cardio- and cerebrovascular events in patients with primary aldosteronism.

Background: Aldosterone plays a detrimental role on the cardiovascular system and PA patients display a higher risk of events compared with EH.

Objectives: The objectives of the study were to compare cardio- and cerebrovascular events in patients with primary aldosteronism (PA) and matched essential hypertension (EH).

Methods: We retrospectively compared the percentage of patients experiencing events at baseline and during a median follow-up of 12 years in 270 PA patients case-control matched 1:3 with EH patients and in PA subtypes [aldosterone-producing adenoma (n = 57); bilateral adrenal hyperplasia (n = 213)] vs matched EH.

Diagnosis and treatment of unilateral forms of primary aldosteronism.

Primary aldosteronism (PA) is now recognized as the most frequent form of secondary arterial hypertension. The importance of a correct and prompt diagnosis of PA is determined by its relevant prevalence, its increased cardiovascular risk compared to essential hypertension and by the possibility of reversing this increased risk with a targeted therapy. Surgical treatment of unilateral forms of PA (mainly aldosterone-producing adenomas) is at present recommended in well-selected patients because of its cost-effectiveness.

KCNJ5 mutations in European families with nonglucocorticoid remediable familial hyperaldosteronism.

Primary aldosteronism is the most frequent cause of endocrine hypertension. Three forms of familial hyperaldosteronism (FH) have been described, named FH-I to -III. Recently, a mutation of KCNJ5 has been shown to be associated with FH-III, whereas the cause of FH-II is still unknown.

Prevalence and characteristics of familial hyperaldosteronism: the PATOGEN study (Primary Aldosteronism in TOrino-GENetic forms).

Primary aldosteronism (PA) is the most frequent cause of secondary hypertension, and patients display an increased prevalence of cardiovascular events compared with essential hypertensives. To date, 3 familial forms of PA have been described and termed familial hyperaldosteronism types I, II, and III (FH-I to -III). The aim of this study was to investigate the prevalence and clinical characteristics of the 3 forms of FH in a large population of PA patients.

Concurrent primary aldosteronism and subclinical cortisol hypersecretion: a prospective study.

Background: Primary aldosteronism is the most frequent cause of secondary hypertension and is responsible for an increased risk of cardiometabolic complications. A concomitant subtle cortisol hyperproduction could enhance cardiovascular risk. We prospectively estimated the occurrence of subclinical hypercortisolism in primary aldosteronism patients.

Evaluation of primary aldosteronism.

Purpose Of Review: The purpose of this review is to briefly summarize current knowledge on diagnosis and treatment of primary aldosteronism, the most frequent cause of endocrine hypertension.

Recent Findings: The prevalence of primary aldosteronism increases with the severity of hypertension, from 2% in patients with grade 1 hypertension to 20% among resistant hypertensives. The detection of primary aldosteronism is of particular importance, not only because it provides an opportunity for a targeted treatment but also because it has been extensively demonstrated that patients affected by primary aldosteronism are more prone to cardiovascular events and target organ damage than patients with essential hypertension.

Differential diagnosis of primary aldosteronism subtypes.

Primary aldosteronism (PA) is the most frequent endocrine form of secondary hypertension. The recognition of this disease has dramatically increased with the widespread use of a screening test in most hypertensive patients, including those who are normokalemic. Interest in PA has grown since the demonstration that aldosterone has deleterious effects that are, at least in part, independent from its effects on blood pressure.
