During three consecutive days of prazosin treatment in a patient with pheochromocytoma, urinary catecholamine metabolite levels were correlated with plasma renin activity. Suppression of renin plasma activity resulted in sustained hemodynamic and clinical improvement, while no remarkable changes were observed in urinary catecholamine metabolite levels. This suggests that prazosin may interrupt ...
Introduction: Catecholamines are charged neurotransmitters found in the neuroendocrine cells called chromaffins. The release of catecholamine, through a narrow fusion pore of a chromaffin cell requires a charge compensation by other ions to maintain an osmotic balance of charges. The aim of this research is to show that the exocytotic catecholamine release is not associated with the cation flux...
Pheochromocytoma is a tumor originating from chromaffin tissue. It commonly presents with symptoms and signs of catecholamine excess, such as hypertension, tachycardia, headache and sweating. Cardiovascular manifestations include catecholamine-induced cardiomyopathy, which may present as severe left ventricular dysfunction and congestive heart failure. We report a case of pheochromocytoma which...
