Insights

Intermediate monocytes, a specific immune cell type, are linked to cardiovascular disease (CVD) in chronic kidney disease (CKD) patients. Targeting these cells may offer a new therapeutic strategy for reducing CVD risk in this population.

Area of Science:

  • Immunology
  • Nephrology
  • Cardiology

Background:

  • Chronic kidney disease (CKD) is associated with a high burden of cardiovascular disease (CVD).
  • Monocyte activation and chronic microinflammation are key contributors to CVD in CKD.
  • Monocytes are heterogeneous, with three main subsets: classical, intermediate, and nonclassical.

Purpose of the Study:

  • To investigate the role of intermediate monocytes in the development of atherosclerosis in CKD patients.
  • To explore intermediate monocytes as a potential therapeutic target for CVD in CKD.

Main Methods:

  • Analysis of monocyte subset populations (CD14, CD16 expression).
  • Review of epidemiological and laboratory data linking monocyte subsets to CKD and CVD outcomes.
  • Assessment of chemokine receptor expression and cytokine secretion patterns of intermediate monocytes.

Main Results:

  • Intermediate monocytes (CD14(++)CD16(+)) show unique chemokine receptor expression and are prone to secreting proinflammatory cytokines.
  • Numbers of intermediate monocytes increase with declining renal function in CKD.
  • High counts of intermediate monocytes predict adverse outcomes in both early and advanced CKD stages.

Conclusions:

  • Intermediate monocytes play a significant role in atherogenesis and CVD development in CKD patients.
  • The abundance of intermediate monocytes correlates with renal function and clinical outcomes.
  • Targeting intermediate monocytes presents a promising therapeutic avenue for managing CVD in the CKD population.

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 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 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 fluid...

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...

Acute Kidney Injury IV: Diagnostic Studies and Prevention

Accurate diagnosis and effective prevention are critical in managing Acute Kidney Injury (AKI), which is linked to high mortality rates ranging from 10% to 80%. Timely recognition of at-risk patients and careful monitoring can significantly reduce the likelihood of kidney damage.Diagnostic Assessments:The diagnostic process starts with a comprehensive medical history to identify prerenal, intrarenal, and postrenal causes.Prerenal causes, such as dehydration, hypotension, or blood loss, should...
