Insights

High serum uric acid (UA) and high-sensitivity C-reactive protein (hs-CRP) predict cardiovascular death in continuous ambulatory peritoneal dialysis (CAPD) patients. These biomarkers offer valuable insights for risk stratification in CAPD populations.

Area of Science:

  • Nephrology
  • Cardiology
  • Biomarker Research

Background:

  • Cardiovascular disease is a leading cause of mortality in patients undergoing continuous ambulatory peritoneal dialysis (CAPD).
  • Identifying reliable predictors of cardiovascular mortality is crucial for improving patient outcomes in CAPD.
  • Serum uric acid (UA) and high-sensitivity C-reactive protein (hs-CRP) are potential inflammatory and metabolic markers associated with cardiovascular risk.

Purpose of the Study:

  • To evaluate the predictive value of serum uric acid (UA) and high-sensitivity C-reactive protein (hs-CRP) concentrations for three-year cardiovascular-related mortality in CAPD patients.
  • To assess the association of elevated UA and hs-CRP levels with cardiovascular mortality risk in this specific patient cohort.

Main Methods:

  • A cohort of 267 CAPD patients were enrolled, with measurements of serum UA and hs-CRP.
  • Serum UA was determined using an enzymatic colorimetric assay, and hs-CRP was measured via a high-sensitivity particle-enhanced immunoturbidimetric assay.
  • Patients were followed for three years, with cardiovascular-related mortality adjudicated by cardiologists and stroke specialists.

Main Results:

  • Elevated serum UA (mean 415.16 ± 84.28 µmol/L) was observed in 58.4% of patients, and elevated hs-CRP (median 2 [1-4] mg/L) in 12.4%.
  • During the 36-month follow-up, 41 patients (15.4%) experienced cardiovascular-related mortality.
  • Cox regression analysis identified hypertension, diabetes, high serum UA, and high hs-CRP as significant risk factors for cardiovascular mortality (p<0.05). ROC analysis indicated predictive value for both UA (AUC=0.822) and hs-CRP (AUC=0.834).

Conclusions:

  • Elevated serum uric acid and hs-CRP levels are significant predictive factors for cardiovascular-related mortality in patients undergoing CAPD.
  • These biomarkers can aid in identifying CAPD patients at higher risk of cardiovascular events.
  • The findings underscore the importance of monitoring UA and hs-CRP in CAPD patients for cardiovascular risk assessment.

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...

Extracorporeal Removal of Drugs: Continuous Renal Replacement Therapy

Continuous Renal Replacement Therapy (CRRT) is an essential intervention for patients experiencing severe kidney dysfunction. This therapy offers a continuous mechanism for removing fluids and toxins from the bloodstream, leveraging the patient’s blood pressure to facilitate filtration through a specialized filter. This method contrasts with intermittent dialysis, providing a gentler and more consistent removal of waste products and excess fluid, which is particularly beneficial in...

Blood Studies for Cardiovascular System II: CRP, Hcy, and Cardiac Natriuretic Peptide Markers

Cardiac biomarkers are critical in diagnosing, prognosing, and managing cardiovascular diseases. Routine measurement of specific biomarkers such as B-type natriuretic peptide (BNP), C-reactive protein (CRP), and homocysteine (Hcy) is common practice in clinical settings to evaluate heart function and predict cardiovascular events.
These markers indicate stress or strain on the heart muscle:

Continuous Renal Replacement Therapy

Continuous Renal Replacement Therapy, also known as CRRT, is a procedural treatment for acute kidney injury (AKI) that gradually removes uremic toxins and fluids while maintaining acid-base balance and stabilizing electrolytes. It is particularly useful for hemodynamically unstable patients. Unlike intermittent hemodialysis, which is faster, CRRT provides a gentler approach over 24 hours, closely mimicking the function of natural kidneys. However, CRRT is not ideal for patients with...

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.
