Filter by: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.
Elevated aldosterone causes moderate to severe increase in blood pressure, and leads to various target organ damage including cardiovascular ones. Aldosterone has been considered one of the important risk factors for cardiovascular and cerebrovascular diseases. Currently, the use of mineralocorticoid receptor antagonists(MRA) has been proven to reduce blood pressure levels, but long-term prognostic data are lacking in hypertensive patients. Therefore, the purpose of this clinical trial is to assess the effect of MRA on cardiovascular disease in patients with Hypertension and Hyperaldosteronemia.
The goal of this pilot, open-label prospective study is to evaluate if the effect of calcium channel blockade on plasma aldosterone levels in people with primary aldosteronism (PA) is due primarily to Cav1.3 blockade. This will be tested by treating participants who have PA with both cinnarizine (Cav1.3 blocker) and nifedipine (Cav1.2 blocker) and evaluating effect on aldosterone levels and blood pressure over a two week course of treatment.
This study aim to understand whether the length of preoperative supine time would affect the AVS outcome.
This study was a single-center randomized controlled trial which lasted 14 days and consisted of two stages (run-in period (stage I) and intervention period (stage II) each contain 7 days without potassium supplement. If participants meet the enrollment criteria at the end of stage I, they were assigned to the low sodium group (50mmol/d) or normal sodium group (100mmol/d), and then continued to finish stage II. The primary outcome was the change in serum potassium after exposure to normal sodium / low sodium diet and the secondary outcome was the assessment of BP change following a normal sodium / low sodium diet. Patients were given nifedipine controlled-release tablets 30 mg/d to lower blood pressure and were not provided any potassium supplements during the two stages. If the subject has an increase in BP (>180/110 mmHg), the dose of nifedipine controlled-release tablets will be increased to 60 mg/d. Patients will be withdrawn from the study if they cannot tolerate the diet or their serum potassium were below 2.8 mmol/L.
collaborative work within 2 hospitals at the CHU of Caen, at the CHRU of Lille, concerning the evaluation of the biological markers of primary hyperaldosteronism (PAH) with the dosage of aldosterone in LC -MS/MS, which is performed in both centers, with two different techniques. The main objective is to define the range of Aldosterone concentrations in LC MS/MS, of renin in an automated method, in populations of healthy volunteers, essential hypertensives, and hypertensives with primary hyperaldosteronism. , in order to establish a threshold for the screening of PAH by the RAR, and for the confirmation of PAH by a dynamic test with an Aldosterone threshold post salt load test.
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.
Primary hyperaldosteronism confers a higher risk of cardiovascular complications compared to essential hypertension. Preliminary data is controversial in regards of excessive maternal fetal and neonatal excessive risks in pregnancy. This study aims at establishing the prevalence of PHA in an population with a recent episode of hypertensive disorder of pregnancy (HDP). The goal is to determine if a universal screening for PHA after a HDP is worthed. The investigators also wish to evaluate the complication rate in pregnant women with PHA compared to women without PHA. This is a prospective cohort study where all eligible women will be screened for PHA after a HDP episode in the last pregnancy. We will then compare PHA women to non PHA women according to pregnancy complications.
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
The study aims to assess the effect of superselective adrenal arterial embolization on ventricular remodeling in primary aldosteronism without lateralized aldosterone secretion by comparing it with spironolactone therapy.
