Insights

Serum complement C3 (C3) levels correlate with the severity of renal arteriolosclerosis in chronic kidney disease (CKD) patients. This finding suggests C3 may be a useful marker for assessing kidney damage in CKD.

Area of Science:

  • Nephrology
  • Immunology
  • Cardiovascular Medicine

Background:

  • Complement C3 (C3) is a key mediator of inflammation.
  • Elevated serum C3 levels are linked to atherosclerosis.
  • Renal arteriolosclerosis is a significant complication in chronic kidney disease (CKD).

Purpose of the Study:

  • To investigate the association between serum C3 levels and the severity of renal arteriolosclerosis in CKD patients.
  • To determine if serum C3 can serve as a biomarker for renal arteriolosclerosis.

Main Methods:

  • Study included 208 non-diabetic CKD patients (stages 1-3) who underwent renal biopsy.
  • Renal arteriolosclerosis was assessed based on hyaline changes and vessel wall thickening.
  • Serum C3 levels were analyzed against arteriolosclerosis severity using univariate and multiple regression analyses.

Main Results:

  • Serum C3 levels positively correlated with age, BMI, blood pressure, triglycerides, LDL, and CRP.
  • Serum C3 levels were inversely correlated with HDL cholesterol.
  • Serum C3 was independently associated with the severity of renal arteriolosclerosis, alongside age, uric acid, and eGFR.

Conclusions:

  • Serum C3 level is a reliable marker for renal arteriolosclerosis in CKD patients.
  • Metabolic syndrome components correlate with serum C3 levels.
  • Inflammation and metabolic syndrome may drive CKD progression via renal arteriolosclerosis.

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...
Chronic Kidney Disease I: Introduction01:25

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...
Diabetic Nephropathy01:28

Diabetic Nephropathy

Definition Diabetic nephropathy is a chronic kidney complication that results from prolonged hyperglycemia.Prevalence It is the most common cause of chronic kidney disease (CKD) and end-stage renal disease (ESRD) worldwide, affecting up to half of individuals with diabetes.Pathophysiology • Sustained hyperglycemia triggers multiple hemodynamic and metabolic changes in the kidney. • Early in the disease, increased renal blood flow and glomerular hyperfiltration occur due to afferent arteriolar...
Renal Corpuscle01:20

Renal Corpuscle

The glomerulus and Bowman's capsule are two essential components of the nephron, which is the functional unit of the kidney. These microscopic structures play a critical role in the process of blood filtration to produce urine.
Glomerulus: Structure and Function
The glomerulus is a tiny, intricate network of capillaries located at the beginning of the nephron. It's enveloped by the Bowman's capsule and receives its blood supply from an afferent arteriole, which divides into numerous capillaries...

Serum Studies: Renal Function Tests

Renal function tests are crucial for assessing kidney health, monitoring disease progression, and evaluating the kidneys' efficiency in waste elimination, fluid balance, and electrolyte regulation. These tests offer critical insights into kidney function, even though routine measurements may appear normal until there is a significant decline in the glomerular filtration rate or GFR. Typically, signs of kidney impairment only become evident when the GFR falls to about 50% of its normal level.

Drug Dosing in Renal Diseases: Estimation of Glomerular Filtration Rate Based on Serum Creatinine Concentration

Glomerular filtration rate (GFR) can be estimated from serum creatinine using the modification of diet in renal disease (MDRD) formula or the chronic kidney disease–epidemiology collaboration (CKD–EPI) equation. Both methods are widely used in clinical practice to assess kidney function and guide treatment decisions.The MDRD equation does not require weight or height measurements and is normalized to the body surface area of 1.73 m², considered the average adult surface area. This equation is...
