Insights

Greater blockade of the renin-angiotensin-aldosterone system (RAAS) may offer renal protection in chronic kidney disease. However, current evidence is insufficient to routinely recommend this approach, especially with proteinuria.

Area of Science:

  • Nephrology
  • Pharmacology
  • Public Health

Background:

  • Chronic kidney disease (CKD) is a global health issue, affecting nearly 15% of the population, driven by hypertension, diabetes, and obesity.
  • Renin-angiotensin-aldosterone system (RAAS) inhibitors are primary treatments for hypertension and proteinuria in CKD patients, slowing disease progression.
  • Proteinuria is a key indicator of CKD progression and a target for RAAS inhibition.

Purpose of the Study:

  • To review the evidence for enhanced RAAS blockade in renal protection for CKD patients.
  • To discuss the practical implications of pharmacological RAAS disruption for kidney health.
  • To evaluate the potential benefits and limitations of intensified RAAS inhibition.

Main Methods:

  • Systematic review of current literature on RAAS inhibition in chronic kidney disease.
  • Analysis of studies investigating combined RAAS inhibitors or supramaximal doses.
  • Examination of evidence related to proteinuria and renal protection.

Main Results:

  • Enhanced RAAS blockade, through combined drugs or higher doses, shows potential for greater renal protection.
  • Proteinuria is a key factor considered in the context of intensified RAAS inhibition.
  • Insufficient evidence currently exists to support routine recommendation of intensified RAAS blockade in CKD.

Conclusions:

  • While enhanced RAAS blockade may offer benefits, further research is needed.
  • The current evidence does not support routine use of intensified RAAS inhibition in CKD.
  • Clinical decisions regarding RAAS inhibition should be individualized based on patient factors and available evidence.

Antihypertensive 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,...

Heart 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...

Antihypertensive 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...
Antihypertensive Drugs: Angiotensin II Receptor Blockers01:30

Antihypertensive 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...
Renal Regulation of Acid-Base Balance01:29

Renal Regulation of Acid-Base Balance

Metabolic reactions in the body produce nonvolatile acids, such as sulfuric acid, which generate an acid load of approximately 1 mEq of H+ per kilogram of body weight daily. Excreting H+ in the urine is essential to balance this acid load.
In the kidneys, cells within the proximal convoluted tubules (PCT) and the collecting ducts secrete hydrogen ions (H+) into the tubular fluid. Specifically, in the PCT, Na+/H+ antiporters secrete H+ while reabsorbing Na+.
However, the intercalated cells in...
