Plasma renin activity in diabetes mellitus
Clinical Science (London, England : 1979)
|March 1, 1979
Summary
Diabetic patients, both with and without hypertension, exhibit elevated plasma renin activity (PRA). This suggests hypersecretion of renin may contribute to hypertension in diabetes.
Area of Science:
- Endocrinology
- Nephrology
- Cardiovascular Medicine
Background:
- Diabetes mellitus is associated with various complications, including hypertension and renal disease.
- The renin-angiotensin system plays a crucial role in blood pressure regulation.
- Elevated plasma renin activity (PRA) has been implicated in hypertensive disorders.
Purpose of the Study:
- To investigate plasma renin activity (PRA) levels in diabetic patients.
- To compare PRA in diabetic patients with and without hypertension and diabetic complications.
- To explore the potential role of renin hypersecretion in diabetic hypertension.
Main Methods:
- Plasma renin activity (PRA) was measured in 76 diabetic patients attending an outpatient clinic.
- Patients included those with untreated hypertension and various diabetic complications.
- Comparisons were made with age- and sex-matched normotensive and hypertensive control subjects.
Main Results:
- Both normotensive and hypertensive diabetic patients showed significantly higher PRA compared to normotensive controls (P < 0.001).
- Hypertensive diabetic patients had higher PRA than matched hypertensive controls (P < 0.005).
- No significant differences in PRA were observed between diabetic patients with or without hypertension/complications.
Conclusions:
- Diabetic patients exhibit elevated plasma renin activity (PRA), irrespective of hypertension status.
- Hypersecretion of renin is the most probable explanation for the observed elevation in PRA.
- These findings suggest a potential link between renin-angiotensin system dysregulation and diabetes-associated hypertension.

01:16Antihypertensive Drugs: Action of Diuretics
Diuretics are antihypertensive drugs used to treat hypertension resulting from sodium and water retention. Sodium, vital for fluid balance and nerve or muscle function, is regulated by the kidneys through millions of nephrons. Blood enters nephrons via afferent arterioles, which branch into capillaries called glomeruli. These filter blood plasma, allowing water and solutes, like sodium ions, to pass through capillary walls into Bowman's capsule. The filtrate then flows through various tubules...
01:17Antihypertensive Drugs: Action of β1 Blockers
β1-receptors are primarily located in the heart and kidneys. In cardiac myocytes, these receptors interact with neurotransmitters released by the sympathetic nervous system during heightened activity or danger. As a result, β1-receptors get activated, initiating a series of biochemical processes. Excessive activation of beta receptors due to chronic stress can abnormally increase heart rate and contractility, resulting in high blood pressure or hypertension. To counteract this, β1-blockers...
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,...
01:28Diabetic 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...
