Insights

Vasohibin-1 (VASH-1), an angiogenesis regulator, is newly found in chronic kidney disease (CKD) kidneys. Its levels correlate with inflammation and kidney damage, suggesting a role in CKD progression.

Area of Science:

  • Nephrology
  • Vascular Biology
  • Renal Pathology

Background:

  • Angiogenesis-related factors are implicated in chronic kidney disease (CKD) progression.
  • The role and distribution of Vasohibin-1 (VASH-1), a negative regulator of angiogenesis, in CKD remain uninvestigated.

Purpose of the Study:

  • To investigate the distribution and clinical significance of VASH-1 in the kidneys of CKD patients.
  • To evaluate the correlation between renal VASH-1 expression and clinicopathological parameters in CKD.

Main Methods:

  • Analysis of renal tissues from 54 Japanese CKD patients and 6 controls.
  • Evaluation of VASH-1 expression in renal cells, glomerular, and interstitial compartments.
  • Correlation analysis between VASH-1 levels and clinical/histological parameters, including crescent formation, interstitial infiltration, and VEGFR-2 expression.

Main Results:

  • VASH-1 was detected in renal endothelial cells, mesangial cells, glomerular crescents, and interstitial inflammatory cells.
  • Significant positive correlations were found between VASH-1+ cell counts and crescent formation, interstitial infiltration, and glomerular VEGFR-2 area.
  • Renal VASH-1 levels showed significant associations with glomerular (r=0.48, p=0.001) and cortical (r=0.64, p<0.0001) crescent formation.

Conclusions:

  • Renal VASH-1 expression is associated with key pathological features of CKD, including inflammation and crescentic lesions.
  • These findings suggest that VASH-1 may be influenced by local inflammation and VEGFR-2 signaling in the context of CKD.
  • VASH-1 warrants further investigation as a potential biomarker or therapeutic target in chronic kidney disease.

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...

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 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...

Renal Drug Excretion: Tubular Secretion

Active tubular secretion is a robust, energy-demanding process that utilizes carrier systems to transport drugs into renal tubules. The active renal secretion systems include the organic anion transporter (OAT) for weak acids and the organic cation transporter (OCT) for weak bases. Structurally similar drugs can compete for the same transporter, potentially leading to drug accumulation and toxicity. However, this principle can be exploited therapeutically. One example is probenecid (Probalan),...

Acute Kidney Injury I: Introduction

Introduction:Acute Kidney Injury (AKI) describes a swift decrease in kidney function occurring over hours to days, characterized by the kidneys' failure to remove waste products from the bloodstream. This leads to dangerous complications like metabolic acidosis, fluid overload, and electrolyte imbalances, such as hyperkalemia, which can cause life-threatening arrhythmias. AKI is common in both hospital and outpatient settings, often triggered by dehydration, sepsis, or exposure to nephrotoxic...

Renal Drug Excretion: Tubular Reabsorption01:25

Renal Drug Excretion: Tubular Reabsorption

Tubular reabsorption, a process occurring post-glomerular filtration of drugs in the renal tubule, is a critical determinant of drug half-life. During the process of renal excretion, as the glomerular filtrate progresses to the distal convoluted tubule (DCT), drugs that are highly permeable, lipophilic, and nonionized undergo passive reabsorption from the tubular fluid into the surrounding peritubular capillaries. This reabsorption process restricts their elimination through the kidneys. This...
