Integrated concentrations of catecholamines in phaeochromocytoma
Lancet (London, England)
|October 16, 1976
Summary
A new blood-sampling system enables catecholamine measurement. This suggests phaeochromocytoma crises stem from active hormone synthesis, not stored release.
Area of Science:
- Endocrinology
- Biochemistry
- Medical Diagnostics
Background:
- Phaeochromocytomas are tumors producing excess catecholamines.
- Understanding catecholamine release mechanisms is crucial for diagnosis and treatment.
- Previous methods limited integrated catecholamine concentration measurements.
Purpose of the Study:
- To introduce a novel blood-sampling system for measuring integrated catecholamine concentrations.
- To investigate the origin of catecholamine crises in patients with phaeochromocytoma.
Main Methods:
- Development and application of a new blood-sampling system.
- Measurement of integrated catecholamine concentrations in three patients with phaeochromocytoma.
Main Results:
- The new system successfully enabled integrated catecholamine measurements.
- Data from three patients indicate catecholamine crises result from active hormone synthesis.
- Findings suggest hormone release is not primarily from a stored pool.
Conclusions:
- The novel blood-sampling system is effective for catecholamine assessment.
- Catecholamine crises in phaeochromocytoma are likely driven by de novo hormone synthesis.
- This challenges the traditional view of crisis etiology, emphasizing active production over release from stores.

01:27Transducer Mechanism: Enzyme-Linked Receptors
Enzyme-linked receptors are cell-surface receptors acting as an enzyme or associating with an enzyme intracellularly. They make excellent drug targets. Drugs can bind to the extracellular ligand-binding domain or directly affect their enzymatic domain and alter their activity.
Major types that are helpful drug targets include:

01:30Classification of Neurotransmitters
Neurotransmitters play a crucial role in the communication between neurons in the autonomic nervous system. Neurons in the autonomic nervous system can be cholinergic or adrenergic depending on the neurotransmitters synthesized. Cholinergic neurons use acetylcholine as their primary neurotransmitter. This includes all the preganglionic fibers of the sympathetic and pre- and postganglionic fibers of the parasympathetic nervous systems. In addition, neurons of the somatic nervous system also use...
01:27Adrenergic Neurons: Neurotransmission
Postganglionic sympathetic fibers (except those supplying the sweat glands) releasing noradrenaline or norepinephrine are called noradrenergic or adrenergic neurons. Noradrenaline, dopamine, adrenaline, or epinephrine are collectively called "catecholamines" as they contain a catechol moiety and an amine side chain. The five stages of neurotransmitter release involve their synthesis, storage, release, reuptake and metabolism.

01:26Adrenergic Receptors: β Subtype
β-adrenoceptors have varied sensitivities towards adrenaline, noradrenaline, and isoprenaline. The order of agonist potency is as follows:
Isoprenaline > Adrenaline > Noradrenaline
Neurotransmitter binding to these receptors causes activation of adenylyl cyclase resulting in increased concentrations of cAMP and modulation of calcium ion channels within the cell. They are further classified into β1, β2, and β3 subtypes.
β1-adrenoceptors: β1-adrenoceptors have equal affinities for...

01:26Cushing Syndrome I: Introduction
Cushing syndrome refers to the collection of clinical manifestations that arise when tissues are exposed to excessive amounts of cortisol or cortisol-like medications over an extended period. Cortisol, a glucocorticoid produced by the adrenal cortex, regulates metabolism, immune responses, and the body’s adaptation to stress. When its concentration remains chronically elevated, these physiological pathways become dysregulated, resulting in the characteristic features of the syndrome.Exogenous...
01:19Cushing Syndrome II: Pathophysiology
Cortisol production is normally governed by the hypothalamic–pituitary–adrenal (HPA) axis, which maintains hormonal balance through tightly regulated feedback mechanisms. Disruption of this regulatory system is central to the development of Cushing syndrome, whether the excess cortisol originates from external medications or internal pathology. Persistent cortisol elevation alters metabolism, immune function, and endocrine signaling, producing the characteristic clinical features of the...
