Unexpected hypotension in catecholamine reversal: a case report
Journal of Medical Case Reports, 2017 Background Catecholamine agents are commonly used to support circulation; however, they may cause unexpected hypotension in a special situation. Here we describe the first unexpected case of hypotension in response to catecholamine agents.

Dietary flavonols contribute to false-positive elevation of homovanillic acid, a marker of catecholamine-secreting tumours [PDF]
, 2011 Background: Urinary homovanillic acid (HVA) measurement is used routinely as a marker of the first test for the screening of catecholamine-secreting tumors and dopamine metabolism, but generates a large number of false-positive results.

Catecholamines in neuroblastoma: Driver of hypertension, or solely a marker of disease?
Cancer Reports, 2022 Background Neuroblastoma is a common solid tumor of childhood and is often associated with hypertension. Potential etiologies contributing to hypertension include renal compression, pain, volume overload, and catecholamine secretion. Cases We completed a

Histamine H1 receptor antagonist attenuates catecholamine surge and organ injury after severe burns
Frontiers in Endocrinology, 2023 Severe burns induce a catecholamine surge, causing severe damage to the organism and raising the possibility of multisystem organ failure. Few strategies are generally acceptable to reduce catecholamine surge and organ injury post-burn.

Frontiers in Behavioral Neuroscience, 2019 Alterations in cortical catecholamine signaling pathways can modulate acute and enduring responses to trauma. Heritable variation in catecholamine signaling is produced by a common functional polymorphism in the catechol-O-methyltransferase (COMT), with ...
