Insights

Chronic kidney disease (CKD) is rising, with current treatments often insufficient. Targeting the endothelin (ET) system, particularly ET-1 via endothelin-A receptors, shows promise for slowing disease progression by reducing blood pressure and proteinuria.

Area of Science:

  • Nephrology
  • Pharmacology
  • Endocrinology

Background:

  • Chronic kidney disease (CKD) incidence and prevalence are increasing globally.
  • Current therapies for CKD often fail to adequately control blood pressure and proteinuria, leading to progressive renal dysfunction.
  • The endothelin (ET) system has emerged as a significant factor in CKD pathogenesis.

Purpose of the Study:

  • To review the current literature on the role of the endothelin system in nondiabetic chronic kidney disease.
  • To evaluate the therapeutic potential of targeting the ET system for managing CKD progression.

Main Methods:

  • Literature review of experimental models and clinical studies.
  • Analysis of the involvement of ET-1 and its receptor, endothelin-A, in renal injury.
  • Examination of data on endothelin receptor antagonists in slowing CKD progression.

Main Results:

  • Experimental models demonstrate ET-1's role in proteinuria, glomerular injury, fibrosis, and inflammation in CKD.
  • Endothelin receptor antagonists have shown potential in preclinical and early clinical studies.
  • Therapies targeting the ET system may slow CKD progression, primarily by lowering blood pressure and proteinuria.

Conclusions:

  • The endothelin system is a critical mediator in the progression of nondiabetic CKD.
  • Targeting the endothelin system, specifically endothelin-A receptor antagonism, represents a promising therapeutic strategy.
  • Further research and clinical application of ET-targeting therapies are warranted for CKD management.

Chronic Kidney Disease I: Introduction

Chronic Kidney Disease (CKD) arises when the kidneys progressively lose their ability to function, ultimately leading to end-stage renal disease. At this advanced stage, the kidneys can no longer filter waste or maintain essential body functions, requiring renal replacement therapy (RRT) through dialysis or a kidney transplant for survival.Early-stage chronic kidney disease and detection challengesIn CKD's early stages, symptoms often remain absent because healthy nephrons compensate for...

Chronic Kidney Disease II: Clinical Manifestations

Chronic Kidney Disease (CKD) progressively impairs multiple body systems due to the accumulation of uremic toxins, which disrupt cellular functions across various organs.Neurologic symptomsNeurologic symptoms often arise early in CKD, as uremic toxin buildup drives changes in cognitive and motor functions. Patients frequently experience fatigue, headache, confusion, difficulty concentrating, and, in severe cases, seizures. Peripheral neuropathy commonly manifests as burning sensations in the...

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...

Acute Kidney Injury II: Pathophysiology

Acute kidney injury (AKI) causes are categorized into three primary categories based on the location of the injury: prerenal, intrarenal (or intrinsic), and postrenal causes. This classification guides clinical management and illustrates how different pathways can impair kidney function.Etiology and Pathophysiology of Acute Kidney Injury1. Prerenal causesEtiology: Prerenal Acute Kidney Injury, the most common type, occurs when reduced blood flow to the kidneys decreases filtration capacity...

Chronic Kidney Disease IV: Nursing Management

Nursing management is essential for preventing complications, maintaining stability, and improving patients' quality of life in chronic kidney disease (CKD). By using a structured approach, nurses help slow CKD progression and support effective patient care​.1. Comprehensive patient assessmentEffective management begins with nurses reviewing the patient’s medical history, and identifying key risk factors like diabetes, hypertension, and nephrotoxic drug use. Nurses assess signs of...
