ALDOSTERONISMO SECUNDARIO PDF

Juxtaglomerular tumours are rare causes of secondary hypertension. They typically present with difficult-to-manage hypertension, hypokalemia, hyperreninemia and secondary hyperaldosteronism. The authors describe a clinical case of a 45 years old female patient, with personal history of difficult-to-manage hypertension and hypokalemia since age 35, medicated with four types of anti-hypertensive agents. An analytical study was performed, which revealed secondary hyperaldosteronism [aldosterone

Santiago de Chile. Primary aldosteronism PA is a known cause of hypertension. In the kidney, aldosterone promotes sodium and water reabsorption, increasing the intravascular volume and blood pressure BP. In the cardiovascular system, aldosterone modifies endothelial and smooth muscle cell response, increasing cardiovascular risk in a blood pressure-independent way.

This ratio increases along with the severity ofthe hypertensive disease. The diagnostic work up of PA should confirm the autonomy of aldosterone secretion from the renin-angiotensin system and should differentiate the clinical subtypes of the disease. Other causes are familial hyperaldosteronism FH type I glucocorticoid-remediable aldosteronism , FH-II non glucocorticoid-remediable aldosteronism , primary adrenal hyperplasia and adrenal carcinoma.

This article reviews the prevalence, diagnosis and treatment of PA and also the clinical, biochemical and genetic characteristics ofits different subtypes. Key words: Aldosterone; Hyperaldosteronism; Hypertension. Estos datos apuntan a un nuevo rol de la aldosterona frente al metabolismo de los hidratos de carbono. Otras causas son el hiperaldosteronismo familiar tipo I HF-I aldosteronismo remediable por glucocorticoides y el HF-II aldosteronismo no remediable por glucocorticoides , la hiperplasia adrenal primaria y el carcinoma suprarrenal ACTH , por lo cual los pacientes afectados pueden ser tratados con glucocorticoides.
