Abstract

Insights

Renin inhibitors like aliskiren lower blood pressure and reduce albuminuria in kidney disease patients. However, their impact on hard renal and cardiovascular outcomes in chronic kidney disease (CKD) requires further investigation.

Area of Science:

  • Nephrology
  • Cardiology
  • Pharmacology

Background:

  • Chronic kidney disease (CKD) affects millions globally, increasing cardiovascular risk.
  • Hypertension is a major driver of CKD progression and cardiovascular events.
  • Renin inhibitors represent a therapeutic class targeting the renin-angiotensin-aldosterone system (RAAS).

Purpose of the Study:

  • To review evidence on renin inhibitors for hypertension control in CKD patients.
  • To assess their efficacy in slowing kidney disease progression.
  • To evaluate their role in reducing cardiovascular risk within this population.

Main Methods:

  • Literature review focusing on studies of renin inhibitors, primarily aliskiren.
  • Analysis of preclinical (animal models) and clinical (human) trial data.
  • Examination of effects on blood pressure, renal injury markers, and cardiovascular events.

Main Results:

  • Aliskiren demonstrated efficacy in blood pressure control in normal renal function and reduced albuminuria in early diabetic nephropathy.
  • Animal studies showed improved survival and reduced renal injury with aliskiren.
  • Limited data exists on blood pressure control specifically in CKD patients, though aliskiren has been used safely.

Conclusions:

  • Renin inhibitors, exemplified by aliskiren, effectively reduce albuminuria.
  • The definitive role of renin inhibitors in improving hard renal endpoints and cardiovascular outcomes in CKD remains to be established.
  • Further research is ongoing to clarify their long-term benefits in CKD management.

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...

Chronic Kidney Disease III: Interprofessional Care

Chronic kidney disease (CKD) requires collaborative and comprehensive management. CKD progresses through stages and can lead to end-stage kidney disease (ESKD) if untreated. Interprofessional collaboration and patient education are crucial, enabling patients to manage their health and improve their quality of life.Diagnostic approach for chronic kidney diseaseThe diagnosis of CKD primarily focuses on the glomerular filtration rate (GFR), which assesses kidney function by measuring how well...
Antihypertensive Drugs: Angiotensin-Converting Enzyme Inhibitors01:30

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...

Heart Failure Drugs: Diuretics

Heart failure and kidney perfusion are interconnected in a complex way. Reduced renal perfusion and venous congestion are two significant factors that contribute to renal dysfunction in heart failure. The kidneys, primarily responsible for fluid balance in the body, are adversely affected due to compromised cardiac output and increased venous pressure. In response to reduced renal perfusion, the kidneys activate neurohumoral mechanisms to restore balance. However, these mechanisms can be...
