Insights

Plasma exchange therapy (PE) effectively prevents coronary artery lesions in Kawasaki disease (KD) cases resistant to intravenous immunoglobulin (IVIG). Early PE treatment within 10 days of onset is recommended for optimal outcomes in pediatric patients.

Area of Science:

  • Pediatric Cardiology
  • Immunology
  • Critical Care Medicine

Context:

  • Kawasaki disease (KD) affects 600-800 Japanese children annually, with coronary artery lesions (CALs) being a significant complication.
  • Intravenous immunoglobulin (IVIG) is the standard treatment, but some cases are refractory.

Purpose:

  • To evaluate the efficacy and safety of plasma exchange therapy (PE) as an alternative treatment for KD cases refractory to IVIG.
  • To determine if early intervention with PE can prevent CALs in high-risk KD patients.

Summary:

  • Plasma exchange therapy (PE) was administered to approximately 130 refractory KD cases since 1995.
  • Multivariate analysis showed PE significantly reduced the risk of CALs (odds ratio 0.052, p = 0.0012).
  • PE was found to be a safe and effective prophylactic measure against CALs when initiated early.

Impact:

  • PE is a viable, safe, and effective treatment option for preventing CALs in IVIG-refractory KD.
  • Early initiation of PE (within 10 days of onset) is crucial for maximizing its prophylactic benefits.
  • This study supports the integration of PE into treatment protocols for severe or refractory KD cases.

Extracorporeal Removal of Drugs: Hemoperfusion and Hemofiltration

Hemoperfusion and hemofiltration are critical techniques in medical treatments to eliminate accumulated drugs, metabolites, and electrolytes from the bloodstream. These methods are particularly vital in cases of accidental poisoning and drug overdose.Hemoperfusion involves passing blood through an adsorbent material to remove unwanted substances. The main adsorbents used in hemoperfusion include activated charcoal and Amberlite resins. Activated charcoal can adsorb both polar and nonpolar...

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...

Acute Kidney Injury V: Interprofessional Care

Acute Kidney Injury (AKI) requires a collaborative healthcare approach to restore renal function and prevent complications. Essential management strategies involve monitoring fluid and electrolyte balance, adjusting medications, initiating dialysis when necessary, and providing nutritional support.Fluid and Electrolyte ManagementFluid Monitoring: Regularly monitoring body weight, central venous pressure, and urine output helps detect fluid imbalances early. Patient intake and output are...

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...

Pulmonary Embolism II: Diagnostic Studies and Interprofessional Care

Diagnosing Pulmonary EmbolismDiagnosing pulmonary embolism (PE) involves clinical assessment and advanced imaging tests. The preferred diagnostic tool is the spiral (helical) CT scan or CT angiography (CTA), which uses intravenous contrast media to visualize the pulmonary vasculature and identify emboli.A ventilation-perfusion (V/Q) scan is an alternative for patients unable to receive contrast media. This scan includes both perfusion and ventilation scanning. Perfusion scanning involves...
