Lipocalin, mineralocorticoid receptor
Brief summary
Aldosterone and its target the mineralocorticoid receptor are implied in development of cardiovascular disease such as arterial high blood pressure or cardiac failure. Serum aldosterone level is insufficient to know if the mineralocorticoid receptor is activated or not. The aim of this study is to identify biomarkers of mineralocorticoid receptor activity. The first candidate biomarker is Neutrophil gelatinase-associated lipocalin (NGAL) or lipocalin which being measured in blood or in the urine. According to scientific knowledge's evolution, others biomarkers could be tested later thanks to the blood or urinary samples taken during study.
Detailed description
This study is broken up into 5 groups: The first is a pre-analytical study to determinate optimum conditions for lipocalin samples. The second focuses on intra-individual variations of lipocalin levels in blood and urine. The third determinate the normal values of lipocalin in blood and urine. Fourthly, we study the role of renal function on serum and urines lipocalin levels. Fifthly, we study the role of anti-aldosterone treatment on patients who suffer of primary hyperaldosteronism.
Interventions
Blood test on an empty stomach. Urinary taking on arrival in the service
For the group 5, at the time of the V0 visit, a treatment by aldactone will be set up (posology: 1 to 2 mg/kg).
