Clinical Scorecard: Evaluating the Safety and Effectiveness of Nafamostat Mesylate Compared to Citrate for Anticoagulation in Continuous Renal Replacement Therapy: A Systematic Review and Meta-Analysis

At a Glance

CategoryDetail
ConditionContinuous Renal Replacement Therapy (CRRT)
Key MechanismsNafamostat mesylate (NM) acts as a synthetic serine protease inhibitor, providing anticoagulant effects with a low bleeding risk.
Target PopulationCritically ill patients receiving CRRT.
Care SettingIntensive care units managing acute kidney injury.

Key Highlights

  • NM reduced the risk of bleeding events compared to citrate (RR = 0.54, p = 0.003).
  • No significant differences in filter lifespan or clotting events between NM and citrate.
  • Subgroup analyses indicated NM's effectiveness in high-risk bleeding scenarios.
  • Overall certainty of evidence is low to very low; further high-quality RCTs are needed.
  • NM is widely used in Asia, particularly Japan, for patients with high bleeding risk.

Guideline-Based Recommendations

Diagnosis

    Management

    • Consider NM as an alternative anticoagulant for CRRT in patients with contraindications to citrate.

    Monitoring & Follow-up

      Risks

      • Monitor for bleeding events, especially in patients at high risk.

      Patient & Prescribing Data

      Critically ill patients with acute kidney injury requiring CRRT.

      NM may be preferred in patients with a high risk of bleeding or contraindications to citrate.

      Clinical Best Practices

      • Prioritize regional citrate anticoagulation (RCA) over heparin when possible.
      • Evaluate individual patient risk factors when selecting anticoagulation strategies.
