Outcomes after medical treatment for primary aldosteronism: an international consensus and analysis of treatment response in an international cohort.

Background: Primary aldosteronism can be treated medically but there is no standardised method to evaluate treatment outcomes. We aimed to develop criteria for assessing the outcomes of targeted medical treatment of primary aldosteronism, analyse outcomes across an international cohort, and identify factors associated with a complete treatment response.

Methods: An international panel of 31 primary aldosteronism experts used the Delphi method to reach consensus on the definition of complete, partial, or absent biochemical and clinical outcomes of medical treatment of primary aldosteronism.

Sex-dependent modulation of T and NK cells and gut microbiome by low sodium diet in patients with primary aldosteronism.

Background: High dietary sodium intake is a major cardiovascular risk factor and adversely affects blood pressure control. Patients with primary aldosteronism (PA) are at increased cardiovascular risk, even after medical treatment, and high dietary sodium intake is common in these patients. Here, we analyze the impact of a moderate dietary sodium restriction on microbiome composition and immunophenotype in patients with PA.

Impact of confirmatory test results on subtype classification and biochemical outcome following unilateral adrenalectomy in patients with primary aldosteronism.

Context: Primary aldosteronism (PA) is the most common form of endocrine hypertension. According to the Endocrine Society Practice Guidelines, the diagnosis of PA requires a pathological screening test result and non-suppressible aldosterone levels during confirmatory testing. Sequential testing with more than one confirmatory test may result in discordant test results.

Impact of Cortisol-Cosecretion on Adrenal Venous Sampling Results in Primary Aldosteronism: Study of 225 Cases.

: Mild autonomous cortisol secretion (MACS) can coexist with primary aldosteronism (PA). The purpose of our study was to evaluate whether (MACS) influences parameters analyzed during adrenal venous sampling (AVS) in patients with PA. : Patients with PA from the SPAIN-ALDO Registry and the German Conn's Registry with available 1 mg-dexamethasone suppression test (DST) and AVS were included.

Synthesis of 4-(Phenylamino)quinazoline-2(1H)-thiones Using Green Solvents.

Given the importance of quinazolines and quinazolinethiones in therapeutic and Food and Drug Administration (FDA)-approved molecules, we thought interesting to consider their synthesis in green solvents. We have shown that obtain 4-(arylamino)quinazoline-2-(1H)-thiones and 4-(arylamino)pteridine-2-(1H)-thiones analogues was efficient in green solvents derived from biomass, especially eucalyptol. Although reaction times are somewhat long to achieve good yields, the products were obtained by simple filtration.

Moderate salt restriction in primary aldosteronism improves bone metabolism through attenuation of urinary calcium and phosphate losses.

Accumulating evidence links osteoporosis and dietary salt consumption. Primary aldosteronism (PA) is a model disease with increased dietary salt intake and constitutes an independent risk factor for osteoporosis. We, thus, assessed whether a short-term moderate reduction in salt intake in PA results in detectable osteoanabolic effects.

Sleep disturbances in primary aldosteronism are associated to depressive symptoms - Could specific mineralocorticoidreceptors be a common pathway?

Symptoms of depression and anxiety are frequent in patients with primary aldosteronism (PA) and are supposed to be independent risk factors for cardiovascular diseases (CVD). As patients with PA have an increased cardiovascular risk compared to patients with essential hypertension, sleep disturbances, which often accompany depressive and anxiety symptoms, may be an additional contributor to the cardiometabolic consequences of PA. To clarify this possible link we investigated 132 patients with PA at baseline and after one year after initiation of treatment either by adrenalectomy (ADX) or mineralocorticoid-receptor-antagonist (MRA).

Effect of mild cortisol cosecretion on body composition and metabolic parameters in patients with primary hyperaldosteronism.

Objective: To investigate the effects of simultaneous cortisol cosecretion (CCS) on body composition in computed tomography (CT)-imaging and metabolic parameters in patients with primary aldosteronism (PA) with the objective of facilitating early detection.

Design: Retrospective cohort study.

Patients: Forty-seven patients with PA and CCS confirmed by 1-mg dexamethasone suppression test (DST) with a cutoff of ≥1.

Long-Term Follow-Up of Patients With Elevated Aldosterone-to-Renin Ratio but Negative Confirmatory Test: The Progression of Primary Aldosteronism Phenotypes.

Background: About 10% of patients with arterial hypertension have a positive screening test for primary aldosteronism (PA) and 50% to 70% of them have a negative confirmatory test: the appropriate follow-up of these patients is currently unknown. We investigated the incidence of PA in patients with previous negative confirmatory testing, after at least a 2-year follow-up.

Methods: One hundred eighty-four patients with a previously elevated aldosterone-to-renin ratio followed by a negative confirmatory test were recruited in 2 hypertension centers (Torino and Munich).

Postoperative ACTH-stimulated aldosterone predicts biochemical outcome in primary aldosteronism.

Objective: Primary aldosteronism (PA) is the most common surgically curable cause of hypertension. Unilateral aldosterone-producing adenoma can be treated with adrenalectomy. Clinical and biochemical outcomes are assessed 6-12 months after adrenalectomy according to primary aldosteronism surgical outcome (PASO) consensus criteria.

A novel LC-MS/MS-based assay for the simultaneous quantification of aldosterone-related steroids in human urine.

Objectives: Primary aldosteronism is the most common cause of endocrine hypertension and is associated with significant cardiovascular morbidities. The diagnostic workup depends on determinations of plasma aldosterone and renin which are highly variable and associated with false-positive and false-negative results. Quantification of aldosterone in 24 h urine may provide more reliable results, but the methodology is not well established.

Integration of clinical parameters and CT-based radiomics improves machine learning assisted subtyping of primary hyperaldosteronism.

Objectives: The aim of this study was to investigate an integrated diagnostics approach for prediction of the source of aldosterone overproduction in primary hyperaldosteronism (PA).

Methods: 269 patients from the prospective German Conn Registry with PA were included in this study. After segmentation of adrenal glands in native CT images, radiomic features were calculated.

Salt and Aldosterone - Reciprocal and Combined Effects in Preclinical Models and Humans.

Primary aldosteronism is an endocrine disorder caused by excessive production of aldosterone by the adrenal glands, and is recognized as the most important cause of endocrine hypertension. With specific therapy, this type of hypertension is potentially curable. In the general population, high salt intake increases the risk for cardiovascular diseases like stroke.

Fatty acid desaturase 2 determines the lipidomic landscape and steroidogenic function of the adrenal gland.

Corticosteroids regulate vital processes, including stress responses, systemic metabolism, and blood pressure. Here, we show that corticosteroid synthesis is related to the polyunsaturated fatty acid (PUFA) content of mitochondrial phospholipids in adrenocortical cells. Inhibition of the rate-limiting enzyme of PUFA synthesis, fatty acid desaturase 2 (FADS2), leads to perturbations in the mitochondrial lipidome and diminishes steroidogenesis.

Moderate dietary salt restriction improves blood pressure and mental well-being in patients with primary aldosteronism: The salt CONNtrol trial.

Background: Primary aldosteronism (PA) is a frequent cause of hypertension. Aldosterone excess together with high dietary salt intake aggravates cardiovascular damage, despite guideline-recommended mineralocorticoid receptor antagonist (MRA) treatment.

Objectives: To investigate the antihypertensive impact of a moderate dietary salt restriction and associated physiological changes, including mental well-being.

Differential central regulatory mineralocorticoidreceptor systems for anxiety and depression - Could KCNJ5 be an interesting target for further investigations in major depression?

The mineralocorticoid receptor (MR) is suggested to play a role in the pathophysiology of depression and anxiety. Main support comes from studies in patients with primary aldosteronism (PA) which suggested different central pathways for depression and anxiety mediated via the MR and gender differences. We investigated 118 patients with PA over 3 years using self-rating questionnaires for anxiety (GAD-7) and depression (PHQD) at baseline and once a year under specific treatment with adrenalectomy (ADX; n = 48) or a MR antagonist (MRA; n = 70).

Influence of cortisol cosecretion on non-ACTH-stimulated adrenal venous sampling in primary aldosteronism: a retrospective cohort study.

Objective: Cortisol measurements are essential for the interpretation of adrenal venous samplings (AVS) in primary aldosteronism (PA). Cortisol cosecretion may influence AVS indices. We aimed to investigate whether cortisol cosecretion affects non-adrenocorticotrophic hormone (ACTH)-stimulated AVS results.

[Conn's syndrome-Frequent and still too rarely diagnosed to underdiagnosed].

Conn's syndrome represents the most common cause of endocrine hypertension and is associated with an increased cardiovascular risk, a series of comorbidities (including type 2 diabetes mellitus) and with their frequent occurrence. Therefore, a correct and rapid diagnosis is of essential importance. Measurement of the aldosterone-renin ratio is used as a first screening test for primary aldosteronism.

Renin, a marker for left ventricular hypertrophy, in primary aldosteronism: a cohort study.

Context: Primary aldosteronism (PA) causes left ventricular hypertrophy (LVH) via hemodynamic factors and directly by aldosterone effects. Specific treatment by mineralocorticoid receptor antagonists (MRA) or adrenalectomy (ADX) has been reported to improve LVH. However, the cardiovascular benefit could depend on plasma renin concentration (PRC) in patients on MRA.
