NCT02756754
The aim of the study is to evaluate the novel use of adrenal radiofrequency ablation on a prospective cohort of patients with primary aldosteronism and unilateral adrenal adenoma concerning the efficacy on blood pressure control. The safety of the procedure is one of the secondary outcomes.
NCT04605549
This is a multicenter, open-label study in adult patients with PA to evaluate the effectiveness and safety of CIN-107 after up to 12 weeks of treatment (Part 1), and then for eligible, consenting patients follow patients in Part 2 for up to 74 weeks for evidence of long-term safety and tolerability.
NCT05405101
The primary objective of WAVE is to test the hypothesis that thermal ablation (microwave or RFA) is non-inferior to surgery in the biochemical (and if so, in the clinical) cure of unilateral PA, according to the international consensus PASO criteria. Secondary objectives are to determine whether either intervention is superior to the other in relation to the following outcomes. Where no superiority of either intervention is established, non-inferiority of thermal ablation against adrenalectomy will be sought. * Frequency and severity of adverse events * Length of inpatient stay * Patient satisfaction * Quality of life * Return to activities of daily living An additional secondary objective in the thermal ablation group alone will be anatomical efficacy of ablation.
NCT06833437
To validate the accuracy of 68Ga-Pentixafor PET/CT and adrenal venous sampling (AVS) in subtype diagnosis of PA/ACS patients with adrenal nodules, based on biochemical and clinical remission outcomes, and to determine whether the diagnostic accuracy of 68Ga-Pentixafor PET/CT is non-inferior to AVS.
NCT07378176
Primary aldosteronism (PA) is the most common cause of secondary hypertension, and patients with PA have a significantly higher risk of developing cardiovascular and renal complications compared with those with essential hypertension. However, PA remains substantially underdiagnosed and undertreated in clinical practice, and relevant research data on the short-term and long-term prognosis of PA patients in the Chinese population are particularly scarce. This is a multicenter, prospective cohort study designed to systematically collect real-world clinical data of PA patients, including baseline clinical characteristics, etiological subtypes, diagnostic and therapeutic strategies, and long-term follow-up outcomes. Through 5 years of standardized follow-up, this study will analyze the differences in treatment efficacy among PA patients with different pathological subtypes (e.g., adrenal adenoma, adrenal hyperplasia), evaluate the short-term therapeutic efficacy and long-term prognosis of PA patients undergoing different treatment modalities including pharmacotherapy, surgery and interventional therapy, and explore the risk factors for adverse clinical outcomes. Ultimately, it will provide high-quality real-world evidence-based data to optimize the clinical diagnosis and management of PA and improve the long-term prognosis of affected patients.
NCT06941116
This prospective, single-center observational study aims to evaluate whether a steroid-based screening method can more accurately identify Primary Aldosteronism (PA) in hypertensive patients who remain on their usual antihypertensive medications, compared with the conventional aldosterone-to-renin ratio (ARR). PA is a common, potentially curable subtype of secondary hypertension that carries increased cardiovascular risk when undiagnosed or untreated. However, current screening protocols recommend "medication washout" or switching to minimally interfering drugs, which may pose safety concerns and add complexity. In this study, approximately 406 participants (ages 18-75) with diagnosed hypertension and on at least one interfering antihypertensive drug (such as ACE inhibitors, ARBs, beta-blockers, diuretics, or calcium channel blockers) will be enrolled at the Department of Endocrinology, The First Affiliated Hospital of Chongqing Medical University. Each participant will undergo two rounds of blood sampling-first while continuing their usual antihypertensive regimen (the "on-medication" state) and second following a standardized washout/switch period (the "standard state"), if medically feasible. At both stages, levels of plasma aldosterone, renin, and a broad panel of adrenal steroid hormones will be measured by liquid chromatography-tandem mass spectrometry. By comparing diagnostic performance (e.g., sensitivity, specificity, and area under the receiver operating characteristic curve) of the steroid-based screening versus the ARR, the study seeks to determine whether steroid profiling improves accuracy under real-world treatment conditions. Findings may help refine PA screening strategies, reduce the need for extensive medication adjustments, and contribute to better clinical management of hypertension.
NCT07298954
This study is a prospective, multicenter, randomized clinical trial aimed to compare the impact of three AVS diagnostic strategies on the clinical outcomes of patients with primary aldosteronism. The strategies include sequential combined AVS (non-ACTH-stimulated followed by ACTH-stimulated AVS), non- ACTH-stimulated AVS alone, and ACTH-stimulated AVS alone. The findings of this study will provide critical evidence for the clinical practice standards of AVS.
NCT07111351
Primary aldosteronism is a prevalent yet underdiagnosed cause of secondary hypertension, contributing to significant cardiovascular morbidity and renal dysfunction. Despite affecting up to 20% of hypertensive patients, PA is frequently missed because it lacks distinctive clinical features and often presents with nonspecific symptoms like resistant hypertension or subtle electrolyte imbalances. The diagnostic pathway involves a stepwise approach: initial screening via the aldosterone-to-renin ratio, confirmatory testing (e.g., saline suppression or captopril challenge), and subtype differentiation using adrenal venous sampling to distinguish unilateral adenoma from bilateral hyperplasia. This complexity, combined with clinician unfamiliarity and variable access to specialized centers, perpetuates underdiagnosis. Early identification and tailored treatment are paramount in improving outcomes for patients with primary aldosteronism. In this study, we will conduct a comprehensive multi-omics analysis on three sample types: 1) blood and urine samples from patients with primary aldosteronism, primary hypertension, and healthy controls; and 2) adrenal tissue samples from patients undergoing adrenalectomy for aldosterone-producing adenomas. We aim to systematically identify differentially expressed biomarkers that could serve as potential early diagnostic markers for primary aldosteronism. The findings may provide new insights into disease pathogenesis and contribute to improving early detection and personalized treatment strategies for this condition.
NCT06100367
* 10% of patients with hypertension potentially have the treatable condition - primary aldosteronism (PA). This is caused by either bilateral adrenal disease (\~40%), managed with lifelong medications; or unilateral disease (\~60%), cured with laparoscopic surgery (adrenalectomy). Current diagnosis of PA includes a screening test with aldosterone-renin ratio, followed by a confirmatory salt loading test (in most patients) to demonstrate unsuppressed aldosterone levels. Of note, some patients with suppressed aldosterone after confirmatory tests (also termed low-renin hypertension) may also have unilateral adrenal tumors. * The difficulty with identifying curable unilateral disease is due to adrenal vein sampling (AVS): an invasive, and technically-difficult procedure. An alternative novel imaging, 11C-Metomidate Positron emission tomography-computed tomography (PET-CT), can detect adrenal tumors which are over-producing aldosterone. It is non-invasive, non-operator-dependent, and potentially may identify more patients with curable unilateral disease. The results from our pilot study in 25 patients with confirmed PA (ClinicalTrials.gov NCT03990701, PA\_CURE) showed that 11C-Metomidate PET-CT exhibited comparable performance to AVS in subtyping PA, and this should be validated in a larger study. * In addition, 11C-Metomidate is also able to differentiate adrenocortical lesions in the adrenal gland from other lesions found in adrenal tissue, such as adrenomedullary lesions (e.g. pheochromocytoma). * Hence, the investigators hypothesize that 11C-metomidate PET-CT can accurately (1) identify patients with surgically curable unilateral adrenal disease among hypertensive Asians with primary aldosteronism (PA\_CURE 2 / PA\_MTO EH study) and (2) differentiate adrenocortical lesions from other lesions in patients with adrenal tumors (PA\_MTO AT study)
NCT07182175
The main goal of this study is to follow patients with functional adrenal tumors during the time before and after their surgery. The main questions it aims to answer are: * What heart and blood pressure changes do patients with different types of adrenal tumors have before surgery? * What factors affect how the heart and blood pressure recover after surgery? * Do the heart and blood pressure conditions before surgery influence recovery and the risk of heart or brain problems after surgery? Patients will have heart ultrasound checks and health monitoring before and after surgery. The results will help doctors choose the right medicines before surgery, better understand possible risks during the operation, and make safer treatment plans for patients with functional adrenal tumors.
NCT07137364
The goal of this observational study is to learn about the optimal dose of spironolactone treatment and the long-term outcomes on cardiovascular and cerebrovascular events in patients with lateralized PA who are unwilling to undergo surgery. The main question it aims to answer is: 1. What is the long-term effect of spironolactone treatment for lateralized PA? 2. What is the optimal dose of spironolactone treatment for the relief of renin inhibition in patients with lateralized PA? Participants will receive spironolactone treatment as part of their regular medical care for more than 12 months, and their clinical indicators, including blood pressure, biochemical remission, cardiovascular and renal damage, and the incidence of cardiovascular and cerebrovascular events, will be analyzed.
NCT04991961
To evaluate the effect of anti-hypertensive medication on efficiency of primary aldosteronism screening and confirmatory test, and to determine the appropriate diagnostic cutoff value for Chinese hypertension patients during antihypertensive drugs therapy.
NCT07027254
This study is a randomized controlled trial to assess the clinical utility of gallium-68 pentixafor PET/CT in the management of primary aldosteronism (PA). We aim to evaluate whether the addition of 68Ga-pentixafor PET/CT to standard adrenal venous sampling (AVS) improves surgical outcomes in patients with unilateral PA.
NCT05765786
The goal of this observational study is to see if there is a cyclical or exaggerated diurnal variation in aldosterone production in people with Primary Aldosteronism.
NCT06569589
The study aims to provide quantitative facts on the pathophysiological changes in tissue Na+ content during Na+/K+ redistribution disorders in patients with PA in response to standard therapy. The investigators hypothesize that patients with primary aldosteronism have excessive Na+ storage in the muscle, which can now be quantified non-invasively using 23NaMRI. In analogy to the role of HbA1c as a metabolic long-term marker in diabetes, the quantifiable changes in muscle Na+ content may deliver the data evidence necessary to justify and conduct randomized diagnostic endpoint outcome trials in the future, with the ultimate aim to improve PA detection rate and treatment.
NCT06980753
The goal of this project is to provide novel technology that will pave the way from the present single-point (analogue) endocrinology towards continuous cortisol and aldosterone monitoring with full time resolution. Current endocrine practice relies on occasional and often random determination of hormone level or functional tests that require a clinical setting. These measurements include sample extraction and analysis in a clinical laboratory rendering such tests laborious and expensive. Most importantly, through the individual variations of hormone oscillation and spatiotemporal distribution of hormones, infrequent hormone measurements have limited diagnostic and prognostic value as the dynamic changes are not captured and relevant intra-individual variability occurs. A requirement for this vision are sensing solutions capable to track hormone dynamics over prolonged periods at high patient comfort (e.g., at home), as targeted by this research proposal. This project has the overarching goals of (1) establishing dynamic interstitial aldosterone and cortisol monitoring as reliable diagnostic tool for cortisol and aldosterone excess or deficiency, and (2) develop a wearable molecular sensing device to detect them accurately.
