Angiotensin-converting enzyme in sarcoidosis: a British study
British Journal of Diseases of the Chest
|October 1, 1979
Summary
Serum angiotensin-converting enzyme (ACE) activity is significantly elevated in active sarcoidosis patients compared to controls. This finding aids in understanding sarcoidosis biomarkers and disease activity.
Area of Science:
- Biochemistry
- Immunology
- Pulmonary Medicine
Background:
- Serum angiotensin-converting enzyme (ACE) is an enzyme involved in various physiological processes.
- Elevated ACE levels have been associated with certain granulomatous diseases, including sarcoidosis.
Purpose of the Study:
- To investigate serum ACE activity in patients with active and inactive sarcoidosis.
- To compare ACE activity between sarcoidosis, tuberculosis, and healthy controls.
- To explore correlations between ACE activity, sex, age, and disease stage in sarcoidosis.
Main Methods:
- Serum samples were collected from healthy controls, active sarcoidosis patients, inactive sarcoidosis patients, and tuberculosis patients.
- Serum ACE activity was measured using a standardized biochemical assay.
- Statistical analyses were performed to compare ACE levels across groups and assess correlations.
Main Results:
- Serum ACE activity was significantly higher in patients with active sarcoidosis compared to healthy controls, inactive sarcoidosis patients, and tuberculosis patients.
- No significant differences in ACE activity were observed between males and females in control or sarcoidosis groups.
- A correlation between ACE activity and age was noted only in the female active-sarcoidosis group.
- ACE activity did not significantly differ across disease Stages I, II, and III in sarcoidosis patients.
Conclusions:
- Elevated serum ACE activity is a significant indicator of active sarcoidosis.
- Serum ACE levels may serve as a biomarker for disease activity in sarcoidosis.
- Further research is warranted to explore the clinical utility of ACE activity in managing sarcoidosis.

01:30Antihypertensive Drugs: Angiotensin-Converting Enzyme Inhibitors
Angiotensin-converting enzyme (ACE), a vital component of the renin-angiotensin-aldosterone system, is abundant in lung endothelial cells. ACE converts the inactive decapeptide, angiotensin I, into the active octapeptide, angiotensin II. This potent vasoconstrictor narrows blood vessels, increasing resistance to blood flow and elevating blood pressure. Angiotensin II also stimulates aldosterone production, encouraging kidney cells to reabsorb more sodium and water from urine, thereby increasing...
01:30Antihypertensive Drugs: Angiotensin II Receptor Blockers
In the renin-angiotensin-aldosterone system, a hormone called angiotensin II plays a crucial role. It binds to the AT1 receptors in vascular smooth muscles coupled with Gq proteins. The activation of these receptors activates an enzyme called phospholipase C, which releases two molecules: inositol trisphosphate and diacylglycerol. These molecules cause a chain reaction that leads to the phosphorylation of myosin light chains and promotes interaction between actin and myosin, leading to smooth...
01:26Heart Failure Drugs: Inhibitors of Renin-Angiotensin System
The activation of the sympathetic nervous system and the renin-angiotensin-aldosterone system (RAAS) contributes to cardiac remodeling, and inhibiting the RAAS is a pharmacological target in heart failure management. As a result, neurohumoral modulation is a crucial treatment principle for managing heart failure. This approach involves using medications like ACE inhibitors (ACEIs), angiotensin receptor blockers (ARBs), β-blockers, mineralocorticoid receptor antagonists (MRAs), and neutral...
