Serum angiotensin-converting enzyme: elevations in diabetes mellitus
Annals of Internal Medicine
|December 1, 1980
Summary
Elevated serum angiotensin-converting enzyme (ACE) levels were found in 24% of diabetes patients, strongly linked to severe retinopathy. This suggests diabetes must be considered when using ACE levels to diagnose sarcoidosis.
Area of Science:
- Biochemistry
- Endocrinology
- Ophthalmology
Background:
- Serum angiotensin-converting enzyme (ACE) is a key enzyme in the renin-angiotensin system.
- Elevated ACE levels are a known marker for sarcoidosis.
- Diabetes mellitus is a complex metabolic disorder with various systemic complications.
Purpose of the Study:
- To investigate the prevalence of elevated serum ACE levels in patients with diabetes mellitus.
- To determine the correlation between elevated serum ACE levels and diabetic retinopathy.
- To assess the clinical implications of elevated serum ACE in the context of diabetes.
Main Methods:
- Serum samples were collected from 265 patients diagnosed with diabetes mellitus.
- Serum angiotensin-converting enzyme (ACE) levels were measured.
- Patients were assessed for the presence and severity of retinopathy.
- Statistical analysis was performed to evaluate correlations.
Main Results:
- Elevated serum ACE levels were detected in 24% of the studied diabetic patients.
- A strong correlation was observed between elevated ACE levels and severe diabetic retinopathy.
- These findings suggest a potential link between diabetes and increased ACE activity.
Conclusions:
- Diabetes mellitus is associated with elevated serum angiotensin-converting enzyme (ACE) levels.
- The presence of severe retinopathy in diabetic patients may predict higher ACE levels.
- Clinicians should consider diabetes mellitus as a potential confounding factor when interpreting serum ACE levels for sarcoidosis diagnosis.

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...
01:25Antihypertensive Drugs: Direct Renin Inhibitors
The renin-angiotensin-aldosterone system (RAAS) is an intricate physiological pathway involving numerous enzymes and hormones, including renin, angiotensin-converting enzyme (ACE), angiotensin I and II, and aldosterone. Imbalances within this system increase the production of angiotensin II and aldosterone. Increased angiotensin II levels promote vasoconstriction and blood pressure elevation. Concurrently, higher aldosterone levels stimulate sodium and water reabsorption in the kidneys,...
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...
01:24Serum Studies: Renal Function Tests
Renal function tests are crucial for assessing kidney health, monitoring disease progression, and evaluating the kidneys' efficiency in waste elimination, fluid balance, and electrolyte regulation. These tests offer critical insights into kidney function, even though routine measurements may appear normal until there is a significant decline in the glomerular filtration rate or GFR. Typically, signs of kidney impairment only become evident when the GFR falls to about 50% of its normal level.
01:28Diabetic Nephropathy
Definition Diabetic nephropathy is a chronic kidney complication that results from prolonged hyperglycemia.Prevalence It is the most common cause of chronic kidney disease (CKD) and end-stage renal disease (ESRD) worldwide, affecting up to half of individuals with diabetes.Pathophysiology • Sustained hyperglycemia triggers multiple hemodynamic and metabolic changes in the kidney. • Early in the disease, increased renal blood flow and glomerular hyperfiltration occur due to afferent arteriolar...
