Active clinical trials for "Hyperaldosteronism"

To evaluate the effect of anti-hypertensive medication on efficiency of primary aldosteronism screening test, and to determine the appropriate diagnostic cutoff value for Chinese hypertension patients during antihypertensive drugs therapy.

Prevalence of primary aldosteronism (PA) in resistant hypertension is not clear. In addition, emerging evidence supports the role of elevated serum aldosterone in promoting cardiovascular disease, independently from high blood pressure (BP) levels, but current data on this issue are heterogeneous.

The mission of this project is to increase the detection of Primary Aldosteronism (PA), the most common cause of secondary hypertension, which can either be cured surgically or treated with targeted medications.

The purpose of our research is to evaluate the value of ACTH stimulation in AVS especially in lateralization is still controversial.

WHYSKI is a prospective within-patient observational clinical study designed to test the hypothesis that alterations of Na+, K+, water, and the lympho-angiogenetic transcription factor Tonicity Enhancing Binding Protein (TonEBP) mRNA take place in the interstitium of the skin compartment of patients with arterial hypertension due to primary aldosteronism in whom hypertension can be surgically cured.

The study investigators are interested in learning more about how drugs, that are given to children by their health care provider, act in the bodies of children and young adults in hopes to find the most safe and effective dose for children. The primary objective of this study is to evaluate the PK of understudied drugs currently being administered to children per SOC as prescribed by their treating provider.

The human gut microbiome has been associated with many health factors but variability between studies limits the exploration of effects between them. This study aims to systematically characterize the gut microbiota of various critical chronic diseases, compare the similarities and differences of the microbiome signatures linked to different regions and diseases, and further investigate their impacts on microbiota-based diagnostic models.

Elevated aldosterone levels were also shown to contribute to the excess morbidity and mortality. Literature shows aldosterone and renin levels differ between ethnicity and gender. There is no established reference intervals for these two hormone levels in Asian community. We aim to establish reference intervals for plasma aldosterone and direct renin concentrations among Malaysians residing in Sarawak using the chemiluminescent immunoassay (CLIA). This is a cross-sectional study which will be conducted among ambulatory patients, healthy blood donors and healthy volunteers. 300 participants who fulfil study criteria will be recruited after informed consent. Socio-demographic data and anthropometric measurements will be recorded. Blood will be taken for plasma aldosterone, renin, serum potassium and creatinine. Urine will be collected for estimation of 24-hour sodium excretion. Aldosterone and renin reference intervals will be established partitioned for gender.

Primary aldosteronism (PA) is thought to be the most common secondary endocrine form of hypertension. Compared with patients with essential hypertension with similar blood pressure, patients with PA have significantly higher atrial fibrillation, myocardial infarction, heart failure, stroke, deterioration of renal function and all-cause mortality. Therefore, early and systematic implementation of effective surgical or medical treatment is essential to prevent or reverse the excess vascular events and mortality of these patients. The patients with bilateral PA were mainly treated with mineralocorticoid receptor antagonists (MRAs). The MRA spironolactone is effective at lowering BP and reversing the harmful metabolic consequences, but its use is limited by adverse effects such as gynaecomastia, mastodynia, menstrual abnormalities and impotence due to its agonist activity at the progesterone receptor and antagonist activity at the androgen receptor. Finerenone is claimed to be a more selective blocker of the mineralocorticoid receptor than spironolactone being associated with fewer antiandrogenic side-effects. In this study, we will compare the efficacy, safety and tolerability of finerenone versus spironolactone in patients with hypertension associated with primary aldosteronism.

The study aims to assess the effect of superselective adrenal arterial embolization on vascular endothelial function in patients with primary aldosteronism based on brachial artery flow-mediated relaxation
