Insights

Coronary artery disease (CAD) in chronic kidney disease (CKD) patients is deadly due to calcification and inflammation. MicroRNAs (miRNAs) show promise as diagnostic biomarkers for this challenging comorbidity.

Area of Science:

  • Biomedical science
  • Cardiovascular research
  • Nephrology

Background:

  • Coronary artery disease (CAD) is a serious complication in chronic kidney disease (CKD).
  • CKD-associated CAD involves medial calcification, inflamed plaques, chronic inflammation, endothelial dysfunction, and vascular calcification, accelerating atherosclerosis.
  • Delayed diagnosis of CAD in CKD patients due to non-specific symptoms and unreliable diagnostic tools contributes to increased mortality.

Purpose of the Study:

  • To explore the role of microRNAs (miRNAs) as potential biomarkers for CAD in CKD patients.
  • To investigate the potential of circulating miRNAs as stable messengers in extracellular vesicles for cell-to-cell communication relevant to CAD pathophysiology.
  • To assess the translational potential of miRNAs from basic research to clinical practice for diagnosing CAD in CKD.

Main Methods:

  • Literature review on CAD in CKD pathophysiology.
  • Analysis of miRNA biogenesis and function as post-transcriptional regulators.
  • Examination of circulating miRNAs within extracellular vesicles as potential diagnostic markers.

Main Results:

  • miRNAs are implicated in the complex pathophysiologic mechanisms of CAD within the CKD context.
  • Extracellular vesicle-encapsulated miRNAs in circulation offer stability and act as intercellular messengers.
  • miRNAs present a promising avenue for advancing diagnostic capabilities for CAD in CKD.

Conclusions:

  • Circulating miRNAs hold significant potential as non-invasive biomarkers for early CAD detection in CKD patients.
  • Further research into miRNA-based diagnostics could improve patient outcomes by enabling timely intervention.
  • Translational studies are crucial to integrate miRNA analysis into clinical practice for managing CKD comorbidities.

Chronic Kidney Disease I: Introduction

Chronic Kidney Disease (CKD) arises when the kidneys progressively lose their ability to function, ultimately leading to end-stage kidney disease (ESKD). 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...

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 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 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...

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...

Nephrons01:10

Nephrons

The kidneys are intricate organs with millions of working units known as nephrons. Each nephron features two major structures: the renal corpuscle, which facilitates blood plasma filtration, and the renal tubule, which handles the glomerular filtrate. Blood supply is directly linked to the nephrons. The renal corpuscle consists of the glomerulus, a capillary network, and the Bowman's capsule, a double-walled epithelial structure that encases the glomerulus. The filtering of blood plasma...
