Filter by:The goal of this clinical trial is to exploring the role of tubeless after adrenalectomy surgery. The main questions it aims to answer are: 1. The safety of tubeless laparoscopic adrenalectomy； 2. The role of tubeless therapy in rapid recovery after adrenalectomy surgery Participants will be randomly divided into two groups: the non drainage group and the drainage group after laparoscopic adrenal surgery, and their pain, first time out of bed, and intestinal recovery time will be observed.
Screening potential candidates who may benefit from surgery remains challenging for patients diagnosed with primary aldosteronism (PA) accompanied by bilateral adrenal lesions. Although adrenal venous sampling is currently the gold standard, it is a technically cumbersome, challenging, and difficult-to-interpret invasive procedure that requires a cutting-edge facility and radiologists with a high level of expertise, which restricts its widespread use. The present study aimed to assess the comprehensive effect of 68Ga-pentixafor positron emission tomography/computer tomography (PET/CT) on guiding surgical treatments for PA patients with bilateral adrenal lesions.
Background: The adrenal glands are 2 small organs that sit on top of each kidney. They release hormones; these are chemicals that control how the body works. Tumors on or outside the adrenal glands are called functional if they release hormones; they are called nonfunctional if they do not. Doctors who treat adrenal tumors need to know which type a person has. Researchers want to find better ways to learn whether an adrenal tumor is functional. Objective: To see if a new radioactive tracer ([68Ga]Ga-PentixaFor) can make it easier to identify functional adrenal tumors with positron emission tomography (PET) scans. Eligibility: People aged 18 years and older with 1 or more adrenal tumors. They must have increased levels of the hormones aldosterone or cortisol. They must also be enrolled in at least 1 other related NIH study (protocols 19-DK-0066, 18-CH-0031, or 09-C-0242). Design: Participants will be screened. They may have imaging scans. Their ability to perform normal activities will be reviewed. Participants will have one PET scan with the study tracer. The tracer will be given through a tube attached to a needle inserted into a vein. Participants will receive the tracer 1 hour before the scan. They will lie still on a bed while a machine captures images of the inside of their body. The scan will take 45 to 90 minutes. Participants heart rate, blood pressure, and rate of breathing will be checked before, during, and after the scan. Participants will have a follow-up visit 3 days after their scan. This visit can be by phone, email, or in person.
To compare the 68Ga-Pentixafor PET/CT and adrenal vein sampling on the long-term outcomes of primary aldosteronism (PA) patients with adrenal nodule (≥1cm)
This is an observational study to define the cut-off value of 24-hour urinary aldosterone for screening primary aldosteronism in hypertensive patients in our center. Plasma aldosterone and renin measurements are subject to significant intra-individual variability, including variation related to posture, time of day and sodium balance. Aldosterone secretion is not constant and may be subject to diurnal variation. As such one-off testing of ARR, does not consider the salt status of the individual necessitating repetition of tests to ensure false negative or false positive test results are ruled out. The value of accumulated aldosterone in a 24-hour sample has the advantage that it does not depend on circadian variation. This study will help establish the positivity rates of 24-hour urine aldosterone, and test the robustness of current standard guidelines for primary aldosteronism screening and case confirmation. Previous studies reported that primary aldosteronism is associated with a higher risk of CV complications and a higher prevalence of target organ damage. Also, previous studies reported on the association of echocardiographic parameters with circulating or urinary aldosterone. Therefore, we intent to investigate the independent associations of different target organ damage with the urinary excretion of aldosterone.
This research aims to establish clinical evidence for optimal treatment guidelines for adrenal diseases using real-world data. The approach involves building prospective and retrospective patient registries, which will be utilized to develop and conduct research on disease-specific protocols for adrenal disorders. The study targets patients with primary aldosteronism, pheochromocytoma, adrenal cancer, adrenal incidentalomas, and mild autonomous cortisol secretion. Registries for patients with adrenal diseases will be obtained from Seoul National University Hospital and Asan Medical Center, along with securing a common data model. The ultimate goal is to conduct research to generate clinical evidence for adrenal diseases using these resources.
To explore the relationship between perioperative blood pressure and catecholamine concentrations in adrenal venous blood and peripheral venous blood in hypertensive patients with primary aldosteronism (PA) who underwent percutaneous selective adrenal artery embolization (SAAE). In order to elucidate the related phenomena and possible mechanisms of blood pressure fluctuations caused by SAAE treatment in hypertensive patients with PA.
The proposed study is this. Short- and long-term outcomes of adrenalectomy for Primary Aldosteronism (PA) in a single centre. PA is a relatively common problem and considers as the commonest cause of secondary hypertension and can be successfully treated by adrenalectomy. The investigators aim to gather clinical data routinely collected on participants with primary aldosteronism pre-operatively and post-operatively for a short and long term follow up.
This multicenter study intends to combine retrospective analysis and prospective registry to evaluate the success rate and safety of adrenal venous sampling (AVS) via antecubital and femoral approach for patients with primary aldosteronism. The consistency of AVS with pathological results and clinical outcomes, the factors affecting the success of AVS, and the optimal population for AVS will be aslo analyzed in this study.
The aim of this protocol is to assess the presence and severity of primary aldosteronism pathophysiology in patients with type 2 diabetes who have, or are at-risk for developing, chronic kidney disease.
